ABSTRACT
Post World War II, technological and political factors prioritized economic efficiency
in food production, distribution and access. Although this currently delivers benefits such as
the doubling of caloric production and food availability despite geographic constraints, the
food system is becoming implicated both directly and indirectly with a host of environmental
and social issues.
This thesis re-frames food system issues as “wicked problems” (Buchanan, 1992, 15)
and develops a framework of design tactics. The framework is used as a matrix for analyzing
past and current theory and practice based design approaches that engage the food system
and two university food systems. The analysis reveals the practical potential in design tactics
for creating incremental shifts towards holistic food systems that have environmental and
social components, thereby addressing contemporary food system issues.

CHAPTER 1: INTRODUCTION
By re-framing the food system as a wicked problem, this thesis develops a
framework of design thinking tactics that have potential to incrementally shift the
industrial food paradigm towards holistic food systems.
The contemporary U.S. industrial food system is becoming directly and
indirectly linked with a host of environmental and social issues (Wallinga, 2009, 258;
Horrigan et al., 2002, 445; Lobao and Stofferahn, 2007). This is because currently the
food system prioritizes economic efficiency over environmental and social
considerations. For example, over the last forty years, the use of chemical fertilizers
and pesticides has been critical in doubling of caloric food production (Tilman, 1999,
5995). While the increase in food production help meet per capita food demand
(Waggoner, 2005, 17), the use of pesticides and fertilizers also contributes to
increased oil-dependence, water contamination and loss of soil productivity (Berry,
2009, 24; Pollan, 2008, 2; Horrigan et al., 2002, 447). Likewise, in the stage of food
distribution, long distance transportation of food provides benefits such as year round
food supply while also overcoming constraints of geography and seasonality
(Halweil, 2002, 6). This comes, however, at costs such as increasing GHG emissions,
limiting potential for self-sufficiency and prioritizing food shelf life over nutrition and
freshness (Hill, 2008, 2; Pirog et al., 2001, 6). These environmental and social costs
are interconnected and complex and are not addressed by the current food system goal
of maximizing economic efficiency. These costs are discussed in detail in Chapter 2.
Chapter 3 re-frames food system issues as “wicked problems” (Buchanan,
1992, 15) that are defined as “complex, interacting issues evolving in a dynamic
social context. Often, new forms of wicked problems emerge as a result of trying to
2
understand and treat one of them” (Ritchey, 2005, 2). By re-framing food system
issues as wicked, this thesis investigates how design thinking can be involved in
developing and implementing holistic food systems. This is done by synthesizing
methods from designers who apply design thinking strategies, such as Tim Brown,
Bruce Mau and William McDonough. The synthesis creates a framework composed
of five strategies: asking innovative questions, developing holistic goals, building
participatory systems, designing for future upcycling and testing prototypes.
This framework is used as a matrix in Chapter 4 to analyze past and current
theory and practice-based design approaches that engage the food system. The past
examples analyzed are Ebenezer Howard’s Garden Cities of To-morrow, Frank Lloyd
Wright’s Broadacre City, Ludwig Hilberseimer’s New Regional Pattern, and Andrea
Branzi’s Agronica. The current approaches are Urban Agriculture, Agricultural
Urbanism and Continuous Productive Urban Landscapes. The analysis reveals that
Howard’s Garden Cities and Bohn and Viljoen’s CPULs best incorporate holistic
food system goals. Following this is a discussion of common patterns and obstacles
faced by current design approaches in practical implementation.
In order to better understand the role of design in overcoming obstacles faced
by current approaches in practical implementation, two university food system case
studies are analyzed in Chapter 5 through the design thinking framework: SEED
Wayne at Wayne State University, Detroit, Michigan and UMass Initiative at
University of Massachusetts, Amherst, Massachusetts. Universities are uniquely
positioned to develop and apply holistic food systems that contribute to local
economic development and community engagement while also improving local food
accessibility and thus providing economic, environmental and social benefits. This
analysis connects back to Agricultural Urbanism and CPULs and demonstrates how
3
holistic food systems proposed by designers can be incorporated into contemporary
conditions by using the various design thinking tactics in order to to begin addressing
food system issues and incrementally shifting the paradigm towards holistic food
systems.

CHAPTER 2: U.S. INDUSTRIAL FOOD SYSTEM
This chapter introduces a summary of technological and political factors that
contributed to the post world war II industrialization of the food system. Following
this is a discussion on the benefits and issues resulting directly and indirectly from the
food system stages of food production, distribution and access. These stages are
investigated because design can have an immediate impact on them. The discussion of
the food system benefits focuses on the goal of maximizing efficiency. Whereas the
discussion on issues focuses on environmental and social costs. The benefits and costs
are supported by examples derived from multiple disciplines. Next is a summary of
how primary issues lead to secondary issues. This discussion is important for reframing the food system problems as “wicked” and for introducing the need for
“design thinking” tactics to begin addressing them.
Development of the U.S. Industrial Food System
Post World War II, key political and technological factors contributed to the
industrialization of the food system with the intent of maximizing efficiency (Ikerd,
2010, 1; Pollan, 2008, 4). For example, the munitions industry was adapted to develop
fertilizer and pesticide technology with ammonia being the common ingredient both in
bombs and fertilizer (Figure 1). Likewise, there was a shift from manual labor to
mechanized input. Earl Butz, who was President Nixon’s agricultural secretary from
1971-76, supported these changes in response to the challenge of cheaply feeding the
growing middle class and with the intent of expanding U.S. exports in the international
food market (Philpott, 2008, 1). The agricultural secretary envisioned a hyper-efficient
food system that could produce an abundant supply of commodity
5

crops like corn and soy and manipulate them to create inexpensive food options.
These change also allowed the U.S. to increase grain export to foreign markets. This
proved lucrative for U.S exports in 1972 as unfavorable climatic conditions in Russia
led to food shortages (Ganzel, 2009, 1). As a result, the U.S and Russia settled upon
the Russian Food Purchase of 1972, which has since been the largest grain deal
between two nations in the history of the world. In order to achieve his goal of
boosting food production efficiency, Butz promoted farmers to consolidate farmland
6
to “get big or get out” and to grow commodity crops “fence row to fence row”
(Pollan, 2008, 4).
As a result, farmers abandoned traditional land stewardship practices that
“balanced extractive activities with the regenerative capacities of the land” (Elmquist
et al., 2013, 7). Instead they adopted highly specialized crop monocultures (Ikerd,
2008, 1). Monocultures are defined as “fields planted with a single crop species over a
given season, typically over a very large area” (Picone, 2002, 1). Each farmer adopted
the principle that “he could limit his investment to the equipment and routine skills
needed to perform his sole task more efficiently” (Ikerd, 2008, 1).
Likewise, the stage of food distribution saw technological innovations under
President Dwight D. Eisenhower who authorized the construction of the National
Highway System by passing the Federal Aid Highway Act of 1956 (Weingroff, 1996,
1). This provided efficient transportation of food via trucks over long distances
(Halweil, 2002, 6). The stage of food access also saw technological innovations that
maximized efficiency. For example, the overabundance of calories derived from corn
and soy monocultures were manipulated to supply the food market with inexpensive
food options. The idea of eating pre-packaged meals such as “TV Dinners” emerged
during this time.
This model of development prioritized economic efficiency but did not factor
in environmental capital- the ecological systems that support life and social capitalour relationships with each other. It calculated efficiency by factoring in “built
capital” such as machinery, factories and other built infrastructure (Costanza, 2008,
32). At the time, it was assumed that natural and social capital would remain
abundant. However, over time, along with delivering economic efficiency, the food
7
system has become implicated with a host of environmental and social or health
issues.
Current Food System Issues
Following is a discussion on the costs associated with the food system stages
of food production, distribution and access.
Food Production
The advantage of industrial food production is the increase in efficient caloric
output, given the minimal input of labor (Kirschenmann, 2007, 373). Caloric
production has doubled over the last forty years (Tilman, 1999, 5995), and has been
an critical factor in meeting with per capita food demand (Waggoner, 2005, 17). As
mentioned earlier, this efficiency has been made possible by adopting practices such
as monocultures and fertilizer and pesticide application.
However, these practices are contributing to a host of environmental and
social issues (Figure 2). For example, monoculture practices imply absence of crop
rotation, which tend to erode biodiversity, deplete soil nutrients and increase the risk
of pest outbreak (Horrigan et al., 2005, 445). As a result, “modern agriculture has also
come to rely heavily on nutrient inputs obtained from or driven by fossil-fuel based
sources” (Pretty, 2008, 454) to maintain soil fertility. Wendell Berry, environmental
activist, cultural critic and farmer, argues this dependence to be a major drawback:
[…] chemical fertilizers are required in vast amounts, they are increasingly
expensive, and most of them come from sources that are not renewable.
Industrial agriculture is absolutely dependent on them, and this dependence is
one of its fundamental weaknesses (Berry, 2009, 24).

monoculture productivity. Collaged by author, 2015.
The industrial food system’s oil dependence implies that each calorie of food
is backed up by calories of oil, and hence obstructs the food system’s sustainability
post the peak oil period. Food activist, Michael Pollan writes:
[…] chemical fertilizers (made from natural gas), pesticides (made from
petroleum), farm machinery, modern food processing and packaging and
transportation have together transformed a system that in 1940 produced 2.3
calories of food energy for every calorie of fossil-fuel energy it used into one
that now takes 10 calories of fossil-fuel energy to produce a single calorie of
modern supermarket food (Pollan, 2008, 2).
The heavy fossil fuel dependence of industrial food production poses urgent
concern for the food system’s future sustainability, because as Manning puts it, “as
there is more oil in our food, there is less oil in our oil” (2004, 51). While the global
demand for fossil fuels rises, the global production capacity of fossil fuels has peaked
or will do so shortly (Kirschenmann, 2005, 1).
Other environmental issues due to industrial food production include excessive
water consumption, pollution and soil degradation. Research reports that irrigating
9
industrial agricultural fields contributes to water scarcity as it consumes excessive
water with little concern for the natural hydrological cycle that maintains water
availability (V.Gold, 1999, 1). Additionally, Horrigan et al. (2002, 447) state that the
U.S. Environmental Protection Agency has blamed current farming practices for 70%
of the pollution in the nation’s rivers and streams, reporting that more than 173,000
miles of waterways have been polluted by runoff of chemicals, silt and animal waste
from U.S. farmland. This has led to high levels of toxicity in ground and surface
waters, which is turn are connected to water purification costs and other expenses
related to health and decreased recreational opportunities (Tilman et al, 2002, 671).
Water contamination due to chemical run-off from farmland has gained concern on
the national scale, as the Mississippi River and its various tributaries are blamed to be
a major contributor to the dead zone in the Gulf of Mexico. This has led to a condition
called hypoxia in the Gulf, characterized by oxygen depletion, which is “killing off
immobile sea dwellers and driving off mobile sea life such as fish and shrimp”
(Horrigan et al, 2002, 446). In its largest size, the Gulf’s dead zone has been recorded
to be 20,000 square kilometers (Heller, Keoleian, 2000, 22).
Additionally, the industrial food production is documented to have negative
impacts on the soil. On the topic of soil erosion, Berry states that, “it has been
estimated, for instance, that at the present rate of cropland erosion Iowa’s soil will be
exhausted by the year 2050” (2007, 23). The Environmental Working Group states
that even by 1975, Iowa had lost one-half of its topsoil to erosion because of bad
tillage practices. In addition, research suggests that industrial agricultural practices
have caused a decline is soil productivity due to soil compaction, loss of soil organic
matter, water holding capacity, biological activity and soil salination (Horrigan et al,
10
2002, 447; Tilman et al, 2001, 671), which collectively inhibit the long-term selfregulating capacity of the ecosystem.
Berry comments also on industrial agriculture’s impact on community welfare, “I
have seen no attempt to calculate the human cost of such [industrial] farming- by
attrition, displacement, social disruption, etc- I assume because it is incalculable”
(2007, 23). In an extensive case study analysis, Labao and Stofferahn evaluate a pool
of 51 case studies investigating the effects of industrialized farming on community
well being from 1930s to 2007. The conclusion of the investigation stated that that
57% of the communities suffered largely detrimental impacts, 25% suffered mixed
impacts and 18% experienced no detrimental impacts due to industrial farming in the
community. The authors summarize their research as follows “these studies provide a
great deal of evidence over many years by researchers using different research
designs, about the risks of industrialized farming on community well-being” (Labao
and Stofferahn, 2007, 19).
Food Distribution
Technological advances in the transportation sector have enabled the
distribution of greater quantities of food over longer distances. The national and
global food transportation routes have created a “global vending machine” (Halweil,
2002, 6) where foods from around the world travel across centralized production,
processing, distribution and access centers to reach their consumers, while at the same
time overcoming previous constraints of geography and seasonality (Figure 3). As a
result, the average distance travelled by produce from farm to plate is 1500 miles
(Mariola, 2008, 194). Long distance food distribution provides benefits such as
11

transportation sector has improved food availability by overcoming geographic and
seasonality constraints. Collaged by author, 2015.
supplying food to densely populated areas, which are otherwise unable to secure
enough food locally.
However, despite the advantages, long-distance distribution of food is
implicated with environmental and social issues, such as GHG emissions, global
warming, climate change, peak oil, concern over food freshness, local food selfsufficiency and economic and communal instability of small-scale farming
communities. Long distance food transportation is associated with food miles, which
12
is a term for the distance food travels from the location of production to consumption
(Pirog et al, 2001, 9). As mentioned earlier, average fresh produce travels an
estimated 1500 miles from field to plate before being consumed. The farther away
food travels, the more fossil fuel is burnt to transport it. Burning fossil fuels
contributes to GHG emissions, which in turn contribute to concerns over peak oil,
global warming and climate change (Hill, 2008, 2). Moreover, because food has to
travel farther away from where it is grown, food is engineered for long distance travel
and a longer shelf life. This prioritizes food preservation over food taste, freshness
and nutrition (Hill, 2008, 2). Producing food for trade via long distance transportation
limits potential for self-sufficiency and increases dependence on outside sources for
food. For example, research illustrates this trend with the example of apple
consumption in Iowa. In 1870, Iowa farmers grew all apples consumed in Iowa, but
by 1999, 85% of apples consumed in Iowa were imported from outside the state
(Pirog et al., 2001, 6). Additionally, long distance transportation of food is indirectly
connected to the consolidation of large-scale distributors, who have greater buying
power and demand steady and year round supply of products in greater quantity and
at low prices (Kaufman, Baikley, 2000, 65). These distributors generally contract with
far away producers who can meet their demands, steadily all around the year. These
contracts, made lucrative by economies of scale, negatively impact the economic
viability and communal stability of small-scale growers (Ghandour, Goché, 2007, 7).
Food Access
The industrial food system provides the market with a diverse range of lowcost and convenient processed foods. This abundance of inexpensive food options is
connected to the goals of efficiency that drive the food system. The U.S. food system
13
has become the “most efficient in the world, at least in terms of the dollar and cent
costs of production” (Ikerd, 1996, 1). What it does well is “precisely what it was
designed to do, which is to produce cheap calories in great abundance” (Pollan, 2008,
3). The abundance of cheap calories has made its way up the food chain and driven
down the price of processed foods (Figure 4). As a result, Americans spend less on
food than any other country in the world (Gates, 2012, 5). U.S. spending on food has
been declining since 1930s, when a quarter of the disposable American income was
spent on food. Today, the fraction has been reduced to a tenth (Pollan, 2008, 3). This
reduction has been made possible because of the abundant supply of calories derived
from monocultures of corn and soy, which are keystone ingredients in pre-packaged
meals, soda, cereal and other processed foods.
Figure 4: Collage of post World War II (left) and present (right) fast food
advertisements. Collaged by author, 2015
14
However, in an interview, the food activist and journalist, Michael Pollan
points out that the diversity of food items is rather superficial, “there’s really just a
small handful of ingredients being reconfigured into this astounding abundance of
seemingly different things—lots of them have corn and soy and the same sweet food
additives” (Platt, 2013, 1). In other words, the abundant supply of cheap calories is
processed to flood the market with inexpensive food options, rich in salt, sugar and fat
contents but poor in providing nutrition. The consumption of such food items, which
may be out of choice or affordability, is associated with increased risk of several
diseases such as coronary heart disease, cancer, stroke, diabetes, hypertension,
overweight and osteoporosis (Frazao, 1999, 5). According to Pollan, since the 1960,
the percentage of personal income spent on food has plunged from 18% to 9.5% while
percentage of national health care spending has inversely peaked from 5% to 17-18%
(2008, 2). The negative health impacts are expected to continue into the future. The
Journal of the American Medical Association predicted that a child born in 2000 has a
one-in-three chance of developing diabetes and because of diabetes, obesity and other
accompanied health problems (Woolston, 1). These trends imply that as we have
spent less on food, we have spent more on healthcare, suggesting that inexpensive
food has external costs. Pollan aptly recognizes the achievement of a food system that
targets economic efficiency as its end goal, “What an extraordinary achievement for a
civilization: to have developed the one diet that reliably makes its people sick!”
(2009, 3). The negative implications of the industrial food diet are particularly severe
for future generations.
In summary, industrial food production, distribution and access are
technologically and politically supported by goals that prioritize economic efficiency.
While the food system achieves this goal, it directly and indirectly contributes to a
15
host of environmental and social issues. These issues need to be addressed for
ensuring the long-term sustainability of the food system. For the 21st century, the
industrial food system and its myriad of complex problems pose great concern,
suggesting that “we might have to reinvent the food system altogether if we want the
world’s population to stay fed and healthy for another century” (De la Salle, Holland,
2010, 12).
In designing a sustainable food system for the future, a holistic approach that
takes into consideration the complex and interconnected nature of the food system
issues is needed. With respect to the current development model, ecological
economist Robert Costanza holds the view that the future will require the
reconceptualization of criteria that factor into measuring human welfare. This will
require “new vision, new measures, and new institutions” that allow us to see “the
interconnections between built, human, social, and natural capitals, and build real
well-being in a balanced and sustainable way” (2009, 373). This will require the
paradigm to shift from goals that primarily focus on maximizing economic efficiency
to include goals that are more holistic and also account for environmental and social
welfare.

CHAPTER 3: REFRAMING THE ISSUE: DESIGN THINKING
Wicked Problems
Food system issues are complex, interconnected and have broad economic,
environmental and social implications (Wallinga, 2009, 258; Horrigan et al., 2002,
445; Lobao and Stofferahn, 2007). The previous chapter exposes the complexity of
these issues by illustrating how prioritizing short-term economic benefits harbors
long-term environmental and social problems. Complex, interconnected issues with
widespread consequences, such as those associated with the U.S. industrial food
system, are what Horst Rittel and Melvin Webber (1973, 160) call “wicked problems”
(Figure 5). Rittel and Webber developed the wicked problem concept while seeking
an alternative to linear, step-by-step problem solving. Richard Buchanan later brought
the concept into the field of design and defines it as “a class of social system
problems that are ill-formulated, with confusing information, where clients and
decision-makers have conflicting values and the ramifications in the system are
confusing” (1992, 15).
As a result, wicked problems cannot be successfully treated with “traditional
linear, analytical approaches” (Ritchey, 2005, 1). Wicked problems are different from
“tame” problems (Table 1). Tame problems have a relatively well-defined problem
statement, a definite starting point, an objective wrong or right solution and they
belong to a class of similar problems and therefore can be solved in a pre-defined
manner (Buchanan, 1992, 16). On the contrary, wicked problems, by definition are:
Ill-defined, ambiguous and associated with strong moral, political and
professional issues. Since they are strongly stakeholder dependent, there is
often little consensus about what the problem is, let alone how to deal with it.
Above all, wicked problems won’t keep still: they are sets of complex,
interacting issues evolving in a dynamic social context. Often, new forms of
wicked problems emerge as a result of trying to understand and treat one of
them (Ritchey, 2005, 2).
17

supporting the case that food system issues are wicked. By author, 2015
18
Traditional, linear and analytical problem solving approaches using
conventional tools and methods are more suited to solving “tame” problems, while
complex and interconnected problems require an entirely new approach to problem
solving (Ritchey, 2005, 2). Wicked problems, such as the problems in the industrial
food system, therefore require alternative, non-linear design approaches. The theory
of design thinking offers one such non-linear method.

1992, 16).

Problem can be solved using pre-existing
disciplinary data
Complexity of data gathering and
analysis leads to “analysis paralysis”
According to IDEO President and Chief Executive Officer Tim Brown, design
thinking begins with the integrative ability to reshape existing constraints in order to
create innovative solutions (2009, 1). This requires an holistic understanding of the
relationships within a system as a whole (Mascarenhas, 2009, 15). In order to
facilitate a system’s holistic understanding, design thinking involves the creation of a
project “brief.” Brown describes the project brief as “a set of mental constraints that
19
gives the project team a framework from which to begin, benchmarks by which they
can measure progress, and a set of objectives to be realized” (2010, 33).
The project brief in design thinking is composed of design constraints and
creates a framework of specific project goals. At the same time, the framework is
flexible enough to allow breakthrough ideas to emerge (Brown, 2009, 1). This
flexibility is needed for engaging wicked problems, which by definition have no
objective solution and tend to evolve over time. The benefit of creating a project brief
or framework is that it allows for “integrative thinking,” defined as:
[...] the ability to constructively face the tensions of opposing models, and
instead of choosing one at the expense of the other, generating a creative
resolution of the tension in the form of a new model that contains elements of
the individual models, but is superior to each (Rotman School of
Management).
Within the context of the U.S. industrial food system, integrative design
thinking requires understanding the food system as a whole across its different stages
as opposed to an isolated approach to each stage. As mentioned earlier, a major
benefit of the holistic design thinking approach is that it allows the designer to view
interconnections and re-shape existing constraints to create innovative design
solutions (Figure 6). For example, with a linear problem solving approach, the
application of oil-based fertilizers during food production and the disposal of food
waste in landfills during waste management are treated as two separate problems in
two distinct stages of the food system. As a result, in 2010 food and packaging
containers accounted for an estimated 45% of landfill waste (United States
Environmental Protection Agency, 2002, 1) and fertilizer production consumes about
40% of energy in industrial agriculture (Heller, Keoleian, 2000, 40).
20
Figure 6: Diagram contrasting isolated versus an integrative design thinking
approach to the food system. By author, 2015.
Design thinking approaches the same scenario by linking the issues of
fertilizer and waste. For example, food waste can be used to create organic compost
that can then be used in the food production stage as fertilizer, thereby reducing the
need for chemical fertilizers as well as landfill size. The benefit of this holistic
approach addresses not only the immediate problems in the food production and food
waste stages, but also mitigates related problems such as GHG emissions due to
rotting food in landfills and the production of oil-based fertilizers.
This example illustrates the benefits of a holistic and integrative design
thinking framework that is integrative and holistic. This approach has potential for
managing short-term and related long-term problems by re-shaping existing
constrains to create innovative and sustainable food systems.
Design Thinking Tactics
Derived from the work of design thinking strategists Tim Brown’s Change by
Design (2014), William McDonough’s Cradle to cradle: Remaking the way we make
21
things (2002) and Bruce Mau’s Massive Change (2004), the following list represents
key characteristics of design thinking as a problem-solving tool:

These characteristics correspond to the characteristics of wicked problems,
formulating a strategy for addressing these problems (Table 2):

Innovative Questions
Tim Brown, in his TED Talk, Designers- Think Big! encourages designers to
“start asking the right questions” (2009, 1). Brown’s view is supported by the
Canadian designer Bruce Mau’s statement that “it’s not about the world of design, but
the design of the world” (2004, 11). Mau calls upon designers to ask questions that
view design’s adaptability as a way of thinking by fundamentally reassessing existing
systems and processes. This ability to ask questions about accepted processes is
especially critical in addressing wicked problems, which by definition cannot be
solved using pre-defined approaches. Brown argues that, “When we face intractable
social ills we are doomed to failure if we simply ask the same questions over and over
again, expecting to receive different answers.” The benefit in asking new questions is
supported by Brown’s argument that, “the greatest entrepreneurs and creative
23
problem-solvers exhibit an ability to ask surprising and insightful questions” (2011,
2).
Brown provides another important reason for designers to ask creative
questions. He argues that with the progress of industrial society, design’s focus has
been reduced to an ever-smaller canvas (2009, 1). For example, design is becoming
limited to the design of objects as opposed to the design of larger issues such as world
hunger, environmental degradation, and health crises. Brown argues that design can
have a much bigger impact if designers apply design thinking to address wicked
problems.
In the context of the food system, “asking the right questions” encourages the reevaluation of where and how food is grown, processed, distributed, accessed,
consumed and finally disposed. This also includes the re-evaluation of processes,
geographic scales of operations, and the long-term impacts of production inputs and
outputs. These questions re-evaluate food system goals, asking whether or not results
are satisfactory in terms of social, health, and environmental as well as economic
outcomes.
Holistic Goals
Brown (2009, 1) also encourages
designers to take a series of
“divergent” steps (Figure 8) to ensure
that they do not default to conventional
choices but instead make innovative
explorations. The intent here is to
broaden the scope of considerations to

24
develop more holistic goals. Brown’s steps of divergence are similar to the Cradle to
Cradle author and architect William McDonough’s approach of “considering a variety
of isms” (2002, 147) and “diversifying” the scope of design considers (2002, 123).
McDonough emphasizes the expansion of design considerations beyond
immediate economic benefits. According to McDonough, economics alone is too
narrow of an indicator for a system or society’s overall prosperity and success. He
writes:
[…] if prosperity is judged only by increased economic activity, then car
accidents, hospital visits, illnesses (such as cancer), and toxic spills are all signs of
prosperity. Loss of resources, cultural degradation, negative social and
environmental effects, reduction of quality of life- these ills can all be taking
place, an entire region can be in decline, yet they are negated by a simplistic
economic figure that says economic life is good (McDonough, 2002, 36).
This is supported by Brown who anticipates that, “more forms of value beyond
simply cash... is going to be the major theme, not only for design, but also for our
economy as we go forward” (2002, 1).
McDonough points out the drawbacks of placing value exclusively on economic
benefits. He argues that in the race for economic prosperity, other forms of value such
as long-term social activity, environmental impact and cultural activity are being
overlooked. In McDonough’s words, the neglect of environmental and social benefits
is the “consequence of outdated and unintelligent design” (2002, 43).
While encouraging designers to broaden design considerations, McDonough takes
the position that focusing on a singular goal for a project creates instability in the big
picture. He gives the example that businesses focusing on economic benefits alone
miss out on creating value in other sectors. According to McDonough, the real magic
begins when the project begins with pronounced concerns for environment or social
equity, and eventually turns out to be “tremendously productive financially in ways
that would have never been imagined if you’d started from a purely economic
25
perspective” (2002, 154). McDonough
calls upon designers to abandon the
economic gain oriented “strategy of
tragedy” and to implement “a strategy of
change” by broadening the scope of
design considerations and developing
more holistic project goals (2002, 42).
In order to facilitate this strategy of
change, McDonough creates a
Figure 9: Sketch by William
McDonough.

(New York: North Point Press, 2002.)
visualization tool in the shape of a
triangular fractal and designates the each vertex for one of three project goals:
ecology, economy and social equity (Figure 9). McDonough actively applies this to
individual products and buildings as well as effects on towns, cities and countries.
McDonough describes his design process: “as we plan a product or system, we move
around the fractal [visualizing tool], asking questions and looking for answers” (2002,
151). The designer asserts that, “ultimately it is the agenda with which we approach
the making of things that must be truly diverse” (McDonough, 2002, 138).
Developing holistic goals has similar value in the context of the food system. The
industrial food system currently measures benefits primarily through increased
economic efficiency. Developing holistic food system goals means accounting for
environmental and social costs.
Participatory Systems
Design thinking explores the “potential of participation” by encouraging
collaboration across a diverse range of stakeholders in the decision-making process.
26
In order to facilitate this collaboration, Brown proposes that designers develop
“participatory systems” that invite clients and consumers to cross boundaries between
public, for-profit and non-profit sectors. Brown makes the case that design can have
the greatest impact when it is taken out of the hands of designers and put in the hands
of consumers (Brown, 2009, 1).
According to Brown, the benefit of facilitating participatory systems is that it can
shift design from being a “passive relationship between consumer and producer to the
active engagement of everyone in experiences that are meaningful, productive and
profitable” (2009, 1). An added benefit is that developing participatory systems can
incorporate user-feedback into the decision-making process. The direct involvement
of the end-users of a product or a system helps more effectively “address the needs of
the people who will consume a product or service and the infrastructure that enables
it” (Brown, 2011, 1). In this way, developing participatory systems also facilitates
grass-roots solutions as “high-impact solutions bubble up from below rather than
being imposed from the top” (Brown, Wyatt, 2010, 3).
Developing participatory systems creates interdependence among the various
stakeholders involved. McDonough holds the view that recognizing interdependence
within a system promotes diversity and makes the system more resilient, especially
when responding to change. McDonough illustrates the value of creating resilience
through diversity and interdependence through his discussion of ecosystems:
The vitality of ecosystems depends on relationships: what goes on between
species, their uses and exchanges of materials and energy in a given place […]
In such a setting, diversity means strength, and monoculture means weakness.
Remove the threads, one by one, and an ecosystem becomes less stable, less
able to withstand natural catastrophe and disease, less able to stay healthy and
to evolve over time. The more diversity there is, the more productive
functions- for the ecosystem, for the planet- are performed (2010, 121).
27
Developing interdependent participatory systems is especially critical for longterm sustainability. McDonough argues that simplified systems that ignore diversity
create more underlying problems, impeding the system’s long-term sustenance.
Building participatory systems through consumer involvement and between
different stakeholders is especially important for wicked problems in the food system,
For example, it is widely accepted that national and global food industry decisions are
controlled by a handful of transnational corporations (TNCs) that are self-regulating
and driven by goals of maximizing economic efficiency. These corporations have
control over the various stages of the food system through vertical integration (Clapp,
Fuchs, 2009, 160).
By developing participatory systems, however, new kinds of food systems can
encourage civic involvement by inviting consumers to join the decision-making
process. This has potential for expanding food system goals to include environmental
and social benefits. It can also build local resilience in the event of a global market
failure. For example, a distributed set of small but many local food system players
such as co-ops, community gardens and farm-to-institution programs is more resilient
because they are regulated through local consumer participation (Viljoen et al., 2005,
218). The distributed local food system can also recover more effectively from shocks
and changes such as the energy transformations that are expected to occur during the
post peak-oil period.
Designing for the Future
Buchanan writes that the essential problem for designers managing wicked
problems is that they are designing for an unknown result. This implies that the
designer has to “conceive and plan what does not yet exist, and this occurs in the
28
context of the indeterminacy of wicked problems, before the final result is known”
(Buchanan, 1992, 15). McDonough refers to a similar concept called “feed
forwarding” (McDonough, 2002, 145) which adds a temporal dimension to his design
approach. He describes this as a process of “asking ourselves not only what has
worked in the past and present, but what will work in the future. What kind of world
do we intend, and how might we design things in keeping with that vision”
(McDonough, 2002, 145).
Designing for an unknown future involves thinking through the environmental
and social life-cycle impact of a design. With respect to environmental “future
upcycling” (2002, 140), McDonough refers to the concept of eliminating waste by
discussing how nutrient flow and metabolism in nature eliminate the idea of waste
altogether (Figure 10). He argues that it is the responsibility of designers to imitate
natural systems that do not produce waste but in turn replenish interconnected
Figure 10: Cradle to Cradle Principle.

World. By Katrin Geist. At: http://wakeup-world.com/2014/11/26/cradle-to-cradledesign-how-a-biochemist-and-an-architect-are-changing-the-world/
29
systems. He anticipates that, “Ultimately, we want to be designing processes and
products that not only return the biological and technical nutrients they use, but pay
back with interest the energy they consume” (McDonough, 2002, 138).
Eliminating or reducing waste within the food system creates “closed-loop” food
systems that imitate natural systems and are self-regulating (Viljoen et al., 2005, 39).
They neither require external inputs such as chemical and oil-based fertilizers and
pesticides nor produce externalities such as water and soil pollution and health costs.
Instead, they contribute positively to environmental health.
In considering the future social impact of the food system through “feed
forwarding,” designers can consider how food proceeds from one stage of the system
to another and how consumers interact with it. This is important because 81% of the
U.S. population currently resides in urban areas and as a result is disconnected from
most food system stages (The World Bank, 2014, 1). Most consumers are unaware of
where their food comes from or goes after it is disposed of as waste (Berry, 2009, 23).
The present disconnect of consumers from food can be potentially repaired if
designers apply “feed forwarding” (McDonough, 2002, 24) and envision not only
how people eat but also how they interact with food across all stages of the food
system.
Testing Prototypes
Rittel and Webber’s definition of a wicked problem states that wicked problems
cannot be defined without solving them, or by solving part of them (McConnell,
2004, 345). This paradox implies that the problem must be solved once to define it
and then solved again to create solutions that work. It requires an open-ended
30
approach that allows for uncertainty where designers engage the problem by choosing
a starting point, knowing that there is degree of uncertainty involved in this choice.
Brown’s design thinking resolves this paradox through the testing of “prototypes” so
that instead of, “thinking about what to build, [designers can] build in order to think”
(Brown, 2009, 1).
The benefit of this step is that prototypes speed up the process of innovation.
Brown states that, “it is only when we put our ideas out into the world that we really
start to understand their strengths and weaknesses. And the faster we do that, the
faster our ideas evolve.” In this way, prototypes help designers learn about the
viability of their ideas. This is especially applicable for addressing wicked problems,
which by definition do not have an objective solution and require an experimental
approach. In this way, the testing of prototypes helps evolve the design hypothesis
towards “fitter solutions” (Brown, 2009, 1).
Prototypes or experiments can be useful in testing the viability of alternative food
systems as an incremental transition towards alternative systems is more practical
than an abrupt change. In the context of the food system, prototypes can occur at the
various stages of the food system and can range from food growing techniques to
participatory systems that revise measures of progress.
In summary, food system issues are wicked problems that can best be addressed
through design thinking as articulated by Brown, McDonough and Mau. Since
industrialization in the nineteenth century began to change urban/rural relationships
including the food system, designers have articulated a range of approaches that deal
with these new relationships. Considering these through a design thinking framework
provides opportunity to evaluate these methods and adapt components of them to
proposals for alternative, holistic food systems.

CHAPTER 4: DESIGN THINKING ANALYSIS
The previous chapter identifies five design thinking tactics. This chapter utilizes
the design thinking tactics as a theoretical framework and analyses past and current
theory and practice based design approaches that engage the food system. The past
examples analyzed are: Ebenezer Howard’s Garden Cities of To-morrow, Frank
Lloyd Wright’s Broadacre City, Ludwig Hilberseimer’s New Regional Pattern,
Andrea Branzi’s Agronica. The current approaches analyzed are: Urban Agriculture,
Agricultural Urbanism and Continuous Productive Urban Landscapes. The aim of the
analysis is to understand how these approaches apply design thinking tactics and to
understand the role of design in developing holistic food system goals and in their
implementation.
Past Design Approaches: Agrarian Utopias
Twentieth Century designers have typically engaged the food system through the
spatial reconceptualization of the relationship between the “urban” and the “agrarian”
(Waldheim, 2010, 1). Designers have proposed agrarian-utopian models that explore
the possibility of a decentralized form combining components of the urban with the
agrarian.
Following is a brief summary of four agrarian-utopian models proposed by
eminent twentieth century designers: Ebenezer Howard (1898), Frank Lloyd Wright
(1932), Ludwig Hilberseimer (1944) and Andrea Branzi (1995). Apart from Andrea
Branzi’s proposal, the rest of the proposals were in response to uncontrolled urban
growth and congestion since the Industrial Revolution. The uncontrolled urban
growth had caused a “pervasive fear of and revulsion from the nineteenth-century
32
metropolis” (Fishman, 1982, 10). Fishman further explains that the “uncontrollable
forces unleashed” by the industrial revolution and growth were perceived as a
“frightening and unnatural” phenomenon (1982, 10). In response to the negative
social perception of the industrial city, these designers proposed a “radical
reconstruction” (Fishman, 1982, 4) of cities with the belief that physical
reconstruction would not only solve the urban crisis, but also the social crisis of the
time.
These design proposals considered various aspects of urban planning such as
social equity, architecture, transportation, communication and other infrastructure.
However, these proposals were specifically chosen because they engage the food
system either in extensive detail or at least to some extent. In order to keep the
discussion focused on the role of design thinking in developing holistic food systems,
each approach is analyzed through the design thinking theoretical framework outlined
in the previous chapter.
Garden Cities of To-morrow by Ebenezer Howard
The Garden City concept was proposed by the English town planner Sir Ebenezer
Howard in 1898 (Figure 11). Howard’s statement summarizes the core Garden City
concept: “Town and country must be married, and out of this joyous union will spring
a new hope, new life, a new civilization” (Fishman, 1976, 209). In order to visually
communicate this concept, Howard proposed a town magnet and country magnet
diagram and combined them to create a town-country magnet. The town magnet was
associated with advantages such as high wages, opportunities for employment and
free of disadvantages such as “excessive hours of toil, distance from work […] fearful
slums that are the strange, complementary features of modern cities” (Howard, 1898,
33
47). The country magnet was associated with
nature’s beauty and wealth, “beautiful vistas,
lordly parks, violet-scented woods, fresh air,
sounds of rippling water” (Howard, 1898,
470). By combining the town-country magnet,
Howard held the view that:
“Human society and the beauty of nature
are to be enjoyed together. The two
magnets must be made one […] Town is a
symbol of society […] and country is a
symbol of God’s love and care for man”
(Howard, 1898, 48).
The town-country union resulted in the
Garden Cities. The City’s design by Howard
would be a circular form, 1,240 yards from
center to circumference, composing of 6
magnificent boulevards, each 120 feet wide.
The centers were circular spaces dedicated to
beautiful gardens and public buildings, the
rings away from the centers had excellent built
houses with ample surrounding grounds.
Sometimes, the houses had common gardens
and co-operative kitchens for local food
production, preparation and consumption

(Reps. 1). The outer ring of the town was programmed with factories, warehouses,
markets, coal yards, timbre yards et cetera.
In summary, Howard’s Garden City devoted systematic attention to food issues,
by addressing food production, distribution, collective preparation and consumption
(Pothukuchi, 2000, 114). Howard’s proposal was successful in asking insightful
questions about uniting town with country (Fishman, 1976, 209) and facilitating
participatory systems through agricultural cultivation, which according to Howard
would require co-operation amongst farmers and other processionals. The city was
designed to self-regulate for the future as it considered organization of labor,
recycling of urban waste and water. The city’s various residents gained employment
by supplying labor for food production. All the fertilizer input was supplied by
composting the city’s food waste and urban waste water was recycled to provide
agricultural irrigation. The environmental and social components of the Garden City
created a self-regulating and local food system.
Broadacre City by Frank Lloyd Wright
Broadacre City was proposed by the American architect, interior designer, writer
and educator, Frank Lloyd Wright (Figure 12). Wright proposed Broadacre in 1932 as
part of his book The Disappearing City. In his article, Notes Towards a History of
Agrarian Urbanism, Charles Waldheim writes that Broadacre was regarded as the
“clearest crystallization of Wright’s damning critique of the modern industrial city”
(2010, 3). It important to note that Broadacre was conceived by Wright during the
Great Depression when owners of family farms were abandoning their mortgaged
fields and migrating elsewhere (Waldheim, 2010, 4).
35
Perhaps in response to the urban and
agrarian economic crisis, Wright proposed
an organic settlement model across an
“essentially boundless plain of cultivated
landscape” (Waldheim, 2010, 3). Wright
utilized the Jeffersonian grid as its principal
ordering system within which, he designed
varying scales of modern houses which were
interspersed with light industry, small
commercial centers, markets, civic
buildings, communication and transportation
infrastructure (Waldheim, 2010, 3). Wright
envisioned Broadacre residents “to enjoy
houses sited amidst ample subsistence
gardens and small-scale farms” (Waldheim,
2010, 4). The architect believed that human
rights included the right “to the ground
itself” (Wright, 1932, 345).

36
thinking strategy was in asking innovative questions that seek to resolve complex
social problems. The project aimed to resolve the urban and agrarian economic crisis
that was happening at the time of its proposal. Wright’s Broadacre combined the
urban-rural economic constraints to design a new pattern of agro-urban integration
characterized by economic self-subsistence. This economic self-subsistence was made
possible through land-ownership and agricultural involvement in Broadacre
(Waldheim, 2010, 4). Wright allotted a one-acre (4,000 sq meters) plot of land from
federal land reserves to each resident of the city. Through this, Wright encouraged
universal participation in local food production. Wright also engaged the stage of food
distribution. The architect envisioned a “system of roadside markets [which would]
enable the trade, sale, and distribution of personally produced food” (Lapping, 1979,
11). Through landownership and agricultural involvement, Broadacre also fulfilled
the step of building “participatory systems”. However, Broadacre failed to design for
the future. The city’s plan based off of the Jeffersonian grid rarely relented to extant
environmental features such as waterways and topography, thereby not accounting for
future environmental impact. Additionally, Broadacre’s ubiquitous highway, which
encouraged automobile transportation failed to consider designing for the future as it
did not account for the future possibility of running out of non-renewable oil reserves
(Waldheim, 2010, 4).
The New Regional Pattern by Ludwig Hilberseimer
Ludwig Hilberseimer, who was a German architect and urban planner, proposed
the New Regional Pattern (Figure 13). Hilberseimer aimed for an urban
decentralization as a remedy for the ills of the industry city. He proposed for the
“ruralization of the city and an urbanization of the country.” The proposal intended to
37
replace the “figure” or “hierarchy” of the industrial city with the creation of a new
development pattern of dispersed “settlement units” (Bevz, Papoullas, 2014, 4).
In his book, The New City: Principles of Urban Planning (1944), Hilberseimer
presented a settlement pattern with a series of arterial roads, flanked by residential
and work units on either side (1955, 267). Similar to Broadacre, the New Regional
Pattern’s residential units were “adjacent to fields and facilities of recreation [...] with
small farms and vegetable gardens” (Bevz, Papoullas, 2014, 5). Like Wright and
Howard, Hilberseimer highlighted the mutual benefit of bringing together the city and
country:
What is pleasant in the city life
could be combined with the
pleasantness of country life.
The disadvantages of each way
of life would disappear. The
woods and forests along the
river and around the lakes
penetrating into the settlements
would become better recreation
spots than costly recreation
parks. With the adjoining fields
and meadows they would form
a productive landscape
(Hilberseimer, 1955, 267).
However, Hilberseimer’s
scheme differed from Wright’s
abstraction of the Jeffersonian grid,
which did not relent to
environmental features. Instead,
Figure 13: New Regional Pattern
the New Regional Pattern
combined “infrastructural systems

38
with built landscapes and used environmental conditions to produce a radically
reconceived type North American settlement” (Waldheim, 2010, 5). As a result, the
New Regional Pattern was informed by environmental considerations of topography,
hydrology, vegetation and wind patterns.
From the design thinking framework, Hilberseimer’s integration of agriculture as
a source of food production and recreation incorporates the design thinking tactic of
developing holistic goals. Additionally, the New Regional Pattern incorporates the
strategy of designing for the future as the design is environmentally responsive.
Agronica by Andrea Branzi
The Italian architect and designer, Andrea Branzi, proposed Agronica (Figure 14).
Agronica was part of Branzi’s search for models of “weak urbanization” (Waldheim,
2010, 6). The radical utopia proposed the introduction of permeable and weak urban
infrastructure into the landscape for facilitating “fluid urban activities” (Bevz,
Papoullas, 2014, 6). In other words, Branzi proposed a productive agricultural
territory in which “single elements of architecture (roofs, walls, platforms) would
flow and group together or were dispersed according to necessity. In this way, a semi
agricultural territory would be created where temporary service structures could
coagulate” (Bevz, Papoullas, 2014, 6).
Branzi’s Agronica delineated the potential in infrastructure and ecology as nonfigurative drivers of the urban form. Both Branzi and Hilberseimer chose to illustrate
the city as a “continuous system of relational forces and flows as opposed to a
collection of objects” (Bevz, Papoullas, 2014, 6). Implying that Branzi’s work, in
some ways, prefigured the current interest in mapping how financial and ecological
flows shape the modern low-density metropolis (Waldheim, 2014, 8).
39
According to Waldheim, Agronica also explored the potential relationship
between agricultural and energy
production to give way to a “territory for
the new economy” (2014, 8) in which
agricultural production would shape the
urban form. Branzi compared the new
landscape of Agronica to the idea of a
three dimensional agriculture which
would “guarantee the penetration of
territory and space, no longer marked by
closed confines” (Branzi, 2006, 10).
Agronica proposed a weak urban
landscape, which like agriculture would
be free and have no insurmountable
barriers “where architecture [would]
become a free availability of
components and no longer coincided
with the concept of buildings and stable
typologies” (Branzi, 2006, 132).
Branzi’s explorations on the need for
weak urbanism is supported by Juhani
Pallasma’s view on the impact of strong
and weak design principles:
Figure 14: Agronica

The dominant trends of town planning have been based on strong strategies and
strong urban form, whereas the medieval townscape as well as the urban settings
of traditional communities have grown on the basis of weak principles. Strong
strategies are reinforced by the eye, the sense of distant control, whereas weak
principles give rise to the haptic townscape of intimacy and participation
(Pallasmaa, 2000, 5).
By proposing a weak urbanism where the most resilient feature is participation,
Branzi’s Agronica fulfills the design thinking tactic of building participatory systems
and designing for the future. Branzi compares Agronica’s weak urbanism to the
traditional Indian urban landscape, which is:
made up not of architecture but rather of people’s bodies, colorful textiles and the
decorations of their dress, which create[s] a lively fluctuating backdrop that is
seemingly fragile, but in reality very resistant to the impact of the cultural and
technological changes in society” (2006, 26).
In this way, Branzi’s Agronica considers designing for the future by anticipating
the future need for flexible systems that can remain resilient through cultural and
technological changes in society.

Common patterns
Howard, Wright, Hilberseimer and Branzi form a “coherent intellectual
genealogy” (Waldheim, 2010, 2), which offer possibilities for agro-urban integration
for designing holistic food systems. The common pattern across all four models is the
radical decentralization of the urban form. These designers are opposed to the
possibility of “gradual improvement” (Fishman, 1982, 4) and propose the design of a
completely new landscape. This new landscape is designed with no particular site
context, implying that, “the setting of these ideal cities was never any actual location,
but an empty, abstract plain where no contingencies existed” (Fishman, 1982, 6).
As a result, the common and primary drawback across these models is that
they do not pay attention to retrofitting existing cities of their time. This lack of
attention to a particular site is problematic because it does not allow the design to
address a given site’s unique constraints and requirements arising out of distinct
characteristics such as socio-cultural demographics, environmental features, economic
situation et cetera.
Contemporary Design Approaches
This section discusses three currently available theory and practice-based
design approaches that engage the food system. They are urban agriculture (UA),
agricultural urbanism (AU) and continuous productive urban landscapes (CPULs).
This section reviews each design approach through its definition, goal, geographic
scale of operation and extent of food system involvement. Following this is an
analysis of UA, AU and CPULs through the design thinking framework in order to
better understand how these they utilize design thinking tactics for developing holistic
42
food systems. This is followed by a discussion on limitations and obstacles of each
approach.
Urban Agriculture
Urban agriculture has been defined in a variety of ways over time. For the
purpose of this thesis, urban agriculture will be referred to as an umbrella term that
covers a wide range of food growing and distributing practices that can occur in urban
areas (Kauffman, Baikley, 2000, 3).
The history of urban agriculture in the United States dates back to a century.
As early as 1890s, cities like Detroit, New York and Philadelphia were converting
vacant lots into community gardens to grow food for local residents. During
historically critical periods such as the Great Depression (1930s) and post World War
II (1945), communities were producing their own food for gaining employment and
ensuring food security respectively. During the 1970s also, community gardens were
being encouraged as a sign of urban renewal, again with the intent of providing food,
but also for recreational and other social benefits (Lawson, 2005, 195).
Today, urban agriculture in the United States focuses on providing
opportunities to improve food security and access to healthy, culturally appropriate
food (Hodgson, 2003, 14) both economically and geographically. Geographically,
urban agriculture provides healthy food access in “food deserts” (Whelan et al., 2002
2083), where food retail outlets stock only processed foods and do not carry fresh
fruits and vegetables. Economically, urban agriculture provides food affordability for
individuals and families living in poverty (Golden, 2013, 8). Healthy food
accessibility is critical for society’s health. In the city of Detroit which is currently a
leader in urban agriculture initiatives, Dan Carmody, who runs Detroit’s thriving
43
Eastern (food) Market comments on the importance of healthy food accessibility as
follows:
Food is typically one of the central organizing elements. Food is where justice
meets economic viability and environmental sustainability. If you don’t have
those three things, you can’t have a society that endures […] You can’t have a
food system where 20% of the people at the lower end of the economic totem
pole eat only one seventh of the amount of fresh fruits and vegetables that the
people at the top eat. Society can’t afford the healthcare costs of treating
diabetes and hypertension and coronary disease because of their poor diet. We
as a society have to figure out a way that people of all incomes can afford and
access healthy eating. Urban agriculture provides opportunities to create and
increase healthy food accessibility by exploring the potential of food
production and distribution within urban boundaries (Viljoen, Bohn, 2014,
131).
In order to better understand how urban agriculture delivers its goals,
following is a review of urban agriculture through the design thinking framework.
The review explores the adaptability features and the environmental and social
benefits of urban agriculture.
Figure 15: Examples of various urban agriculture typologies
Urban agriculture can be implemented in a variety of typologies (Figure 15)
such as institutional farms and gardens (university, hospital, schools) to commercial
farms, community gardens and farms (Five Borough Farm, 2015, 1). These typologies
can be further categorized into demonstration gardens, food pantry gardens, learning
44
gardens, edible school gardens, restaurant gardens, victory gardens, wellness gardens
et cetera (Phillips, 2013, 94). Moreover, urban agriculture can be prototyped through
a range of physical features, such as in-ground planters, rooftop gardens, portable
panels, greenhouses, hydroponic and aeroponic systems, vertical gardens and so on.
These features can be adapted and installed in indoor as well as outdoor spaces
(Figure 16). The range of prototypes and typologies offered by urban agriculture
advance the design thinking tactic of testing prototypes. Through the testing of
prototypes, unlike past design approaches, urban agriculture can better adapt to a
given site’s constraints.
Figure 16: Examples of various indoor and outdoor urban agriculture prototypes
Additionally, urban agriculture advances the design thinking tactic of
developing holistic goals by offering a range of environmental and social benefits.
The socio-cultural benefits include supplying low-income residents with healthier and
45
more nutritious foods, improving the image of troubled neighborhoods, and
developing self-sufficiency and “civic ownership” among urban residents who grow
their own food (Kaufman, Baikley, 2000, 69). In this way, urban agriculture
initiatives help foster community revitalization and social resilience. The
environmental benefits include local and organic growing of food in urban areas,
thereby minimizing chemical run-off and water pollution (Viljoen et al., 2005, 39).
Growing food close to where it will be eaten reduces food miles, as food has to travel
significantly less distance, thereby cutting down on GHG emissions. Moreover, urban
agriculture provides a positive use for urban waste, by composting and using it as
fertilizer for urban food production (Viljoen et al., 2005, 39). It offers environmental
services such as increasing urban biodiversity, reducing heat-island effects, filtering
and slowing run-off, and aiding in storm-water management (McClintock, Cooper,
2010, 5).
However, despite the site-adaptability features and the range of social and
environmental benefits urban agriculture offers, it faces limitations and obstacles in
practical implementation (Kaufman, Baikley, 2010, 54). The primary limitation of
urban agriculture is that it cannot fully supply the food requirements of a given city or
region. Even the best and most innovative practices of urban agriculture will fall short
of being able to produce enough food for subsistence (De la Salle, Holland, 2010, 23).
Cities will always need to import food from outside sources, however, they will do
“less of it, (and) in a more focused, need oriented way” (Viljoen et al., 2005, 12). The
contributors of urban agriculture’s limitations range from social, institutional and
technical obstacles, discussed as follows. Moreover, “insufficient infrastructure and
supporting services” greatly limit the widespread implementation of urban
agriculture. Successful implementation of urban agriculture requires supporting
46
services beyond just production sites, such as local distribution and access (Lovell,
2010, 2512). However, these supporting services are currently lacking due to lack of
government policy and institutional support. For example, local foundations,
community development corporations, neighborhood organizations, and key state and
federal government agencies tend to offer little support to urban agriculture. This is
because the representatives of these institutions are generally unaware about urban
agriculture’s benefits and are skeptical about long-term durability and significance
(Kaufman, Baikley, 2000, 6). The lack of infrastructure and institutional support calls
for the building of participatory systems between urban agriculture proponents and
key institutional leaders and organizations. Another obstacle in implementing urban
agriculture is the limited access to land on short and long-term basis. This is because
urban agriculture has to compete with other land uses such as industrial, commercial
or residential development, which offer more lucrative incentives for landowners
(Lovell, 2010, 2500). However, the payback needs to expand beyond finances to
include health benefits. For example, research at Rutgers University reveals that under
certain conditions, increase in consumption of vegetables grown in Trenton’s
community gardens saved approximately $500,000 per year in cancer treatment costs
(Baikley, Kaufman, 2000, 71). This supports the need for expanding urban agriculture
results to value health improvement. Finally, lack of successful management and
business skills impedes urban agriculture. Typically, urban agriculture projects tend to
operate too independently and fail to work together to promote the value of urban
agriculture on a larger scale (Kaufman, Baikley, 2000, 73). This lack of cooperation
suggests the need for building participatory systems among various urban agriculture
proponents to increase connectivity and cooperation to give way to a more coherent
urban agriculture movement.
47
In summary, urban agriculture aims to provide geographic and economic
access to healthy foods through urban food production and distribution. It offers a
range of typologies and features by which it can adapt to serve a given site’s
constraints and opportunities. This adaptability component advances the design
thinking tactic of testing prototypes. Urban agriculture also advances the development
of holistic goals by providing environmental and social benefits. However, despite the
wide range of environmental and social benefits urban agriculture can potentially
deliver, it faces various obstacles in practical implementation. The obstacles and
limitations faced by urban agriculture imply the need for building participatory
systems and for making visible the environmental and social benefits offered by urban
agriculture. The most pressing obstacles are lack of institutional and government
policy support, uncertainty about economic returns, lack of food production and
distribution skills, limited access to land and lack of coordination among various
urban agriculture initiatives.
Agricultural Urbanism
The originators of agricultural urbanism terminology, Janine de la Salle and
Mark Holland define it in their book Agricultural Urbanism as a “planning, policy
and design framework for developing a wide range of sustainable food and agriculture
systems” (2010, 30). While urban agriculture focuses on the stages of food production
and distribution alone, agricultural urbanism is more holistic and engages food
production, processing, distribution, access and waste management. Another key
distinction between urban agriculture and agricultural urbanism is that urban
agriculture typically operates in urban areas whereas agricultural urbanism operates
on the urban and regional scales (De la Salle, Holland, 2010, 31).
48
Agricultural urbanism asks design thinking’s innovative question of how to
“re-invite food back into the city to re-forge connections to the rural hinterland” (De
la Salle, Holland, 2010, 29). It attempts to forge these connections to create a
vertically integrated local food system that captures the value of local food as an
economic driver. Vertical integration means that all stages of the local food system,
from production to waste management, are coordinated by a singular business entity
(Jurevicius, 2013, 1). Through the development of vertical integration, agricultural
urbanism advances development of participatory systems. Moreover, agricultural
urbanism proponents highlight that vertical integration of local food systems can
contribute to the local economy and thereby ensure future food security (De la Salle,
Holland, 2010, 34). By contributing to the local economy, agricultural urbanism has
potential to overcome urban agriculture’s drawback of economic viability.
Agricultural urbanism also applies the tactic of designing for the future. For example,
in the scenario that environmental or economic factors disrupt the global food market,
agricultural urbanism provides future resilience and food security (De la Salle,
Holland, 2010, 40).
Agricultural urbanism also improves environmental sustainability by creating
“closed loops” between urban and rural infrastructure. Currently, the urban rural
disconnect has created “open loops” where “large material flows” such as biomass
and biosolids are being inefficiently managed. For example, biomass or corn is grown
in rural areas, shipped to urban areas (which contributes to GHG emissions).
Likewise, biosolids or food wastes from urban areas are landfilled or incinerated (to
further emit GHG emissions). Agricultural urbanism aims to bridge this disconnect
through creating closed-loop cycling of material flows between urban and agricultural
lands, thereby opening up opportunities for “integrated resource management” where
49
“energy, water and organic resources can be exchanged, transformed, and used in
ways that benefit both the food growing and the surrounding area” (De la Salle,
Holland, 2010, 103). In a closed-loop urban rural cycle, food grown in rural areas
would travel less for urban consumption and urban food waste could supply compost
for rural food production.
Therefore, through the creation of a vertically integrated food system that
provides economic resilience and the creation of closed loop food systems that
provide environmental benefits, agricultural urbanism advances the design thinking
tactic of developing holistic goals. Despite these benefits, agricultural urbanism faces
obstacles in practical implementation due to the lack of participatory systems between
public, private, non-profit, and academic groups (De la Salle, Holland, 2010). The key
barrier to agricultural urbanism’s long-term sustainability is that these partnership
systems are complex and constantly in flux. Therefore, in order to ensure long-term
sustainability, agricultural urbanism targets the cooperation of government policy at
the federal and state level (De la Salle, Holland, 2010).
In summary, agricultural urbanism asks the innovative question of how to reinvite food back to the cities and build urban-rural connections. It also expands the
design thinking tactic of developing holistic goals that provide economic and
environmental benefits. It provides economic benefits by promoting vertically
integrated local food systems that are economically viable and which also promote the
design thinking tactic of building participatory systems. It provides environmental
benefits through the creation of closed-loop connections between urban and rural
infrastructure for more efficient and “integrated resource management” (De la Salle,
Holland, 2010, 103). The closed-loop food system mitigates the problem of food
50
waste and minimizes the need for external fertilizer inputs, thereby addressing
environmental issues in industrial food production.
Continuous Productive Urban Landscapes (CPULs)
Continuous Productive Urban Landscapes (Acronym: CPULs, Pronounced:
See-Pulse) is an urban design theory proposed in 2005 by architects and educators
Katrin Bohn and Andre Viljoen. According to the authors, CPULs result from
overlaying the spatial concept of “continuous landscapes” with the sustainable
concept of “productive urban landscapes” (Viljoen et al., 11). The goal of the CPULs
is to be productive in economic, socio-cultural and environmental terms. The primary
generator of “productivity” in CPULs is implementation of food system related
activities such as food production, processing, distribution, access and waste
management in both urban and rural landscapes.
A basic step-by-step
implementation of CPULs can be
understood as follows (Bohn,
Viljoen, Howe, 2005, 13).

Viljoen, A., & Bohn, K. (2014). Second Nature Urban Agriculture: Designing Productive Cities. Routledge
Like agricultural urbanism, CPULs aim to develop urban-rural connections
and engage all the stages of the food system. They expand beyond the urban core and
stretch across peri-urban, sub-urban and rural landscapes. Programmatically, they
provide a range of functions such as parks, urban forests, green lungs, movement axis
et cetera. By doing so, they enable activities typically associated with the rural such as
52
agricultural productivity to occur in the urban and activities of leisure and escape
associated with the rural to take place in the urban. However, CPULs are distinct as
they offer “city traversing open spaces and walking landscapes” (Viljoen et al, 2005,
11) that are activated with food system related activities (Figure 18).
CPULs advance the design thinking strategies of developing holistic goals.
They provide environmental, economic as well as social or educational benefits.
Parallel to agricultural urbanism, CPULs attempt to develop “closed-loop” food
circuits and reduce the embodied energy in food. The growing of food in urban and
peri-urban areas offers potential to “establish a healthy and sustainable balance of
production and consumption [...] It is an effective, practical, but at the same time selfbeneficial way of reducing the embodied energy in contemporary western food
production” (Viljoen et al., 2005, 12). The creation of a closed-loop system provides
environmental benefits at every stage of the food system:
•
Local and organic food production: No pesticide and fertilizer is used in production,
therefore no there is no associated water, soil and air contamination.
•
Local distribution: Local food distribution results in significant reduction of food
miles and GHG emissions. This also helps gain energy independence in the context of
peak oil and reduce embodied energy in food.
•
Local access: CPULs produce abundance of fresh fruits and vegetables and help in
realizing fresh food accessibility for urban residents, both geographically and
financially (Figure 19).
•
Waste: Since food is produced and consumed in and around the city, food wastes are
cycled back into urban and rural food production as compost, thereby reducing the
need for external inputs (chemical fertilizer and pesticides) and cutting down on
environmental costs associated with landfills.
53

Viljoen, A., & Bohn, K. (2014). Second Nature Urban Agriculture: Designing Productive Cities. Routledge
The unique feature of CPULs that makes it distinct from previous approaches is
the emphasis on utilizing food as an educational tool that integrates various aspects of
food sustainability into daily life (Viljoen et al., 2005, 58). According to the authors,
the introduction of food system related activities into daily experiences has potential
to bring people closer to the very processes of the food system that sustain us.
Implying that such integration has not only environmental but also educational
benefits to offer.
The educational benefits have value because a large percentage of the urban
population is so far removed from food related processes (Berry, 2005, 20) and is
unaware of food-related issues. However, urban-rural connections provide
educational opportunities to bridge this disconnect. An example of food education is
how people can make informed food choices by considering their food’s
54
environmental impact. For example, some foods such as processed and meat foods
have higher embodied energy (Horrigan et al, 2002, 445). For example, 1 kg of beef
requires 7 kg of grain and 7000 tons of water to grow the feed-grain. This implies that
cattle have an enormous environmental footprint and are most energy inefficient in
converting grain calories into meat (Horrigan et al, 2002, 445). Such food education
has value in informing eaters about the environmental impact of their food choice.
Another example of educational value is in making informed food choices with
respect to human health. For example, high intake of saturated fats in processed and
meat foods is linked to chronic degenerative diseases (Frazao, 1999, 5). The CPULs
authors also support the argument that unhealthy diets are to be blamed for chronic
diseases as they “generally contain excessive amounts of fat and sugar and
insufficient vitamin and mineral-rich fresh fruit and vegetables or carbohydrate-rich
staples such as bread and potatoes” (Viljoen et al., 2005, 59). The CPULs authors
argue that poor-dietary patterns are due to the lack of education, and the lack of
economic and geographic access to stores providing a range of healthy produce. In
response, the CPULs authors propose that integrating the food system into daily life
experiences is likely to improve dietary pattern by providing access to fresh fruits and
vegetables and by providing education about “where, how and when crops are grown”
(Viljoen et al., 2005, 60).
Another important component of CPULs is a focus on implementing urban
agriculture into key institutions. For example, CPULs authors hold the view that
incorporating food growing activities into schools for educational purposes has
potential to supplement traditional subjects like sciences, geography and newer crosscurriculum subjects like environmental sciences. The benefit of food integration into
academic institutions has potential to enhance “quality of life of students and citizens
55
by providing a change of environment and a heightened sensual experience, which is
not reliant upon the trappings of consumerism” (Viljoen et al., 2005, 58). From the
design thinking framework, such integration could help overcome food system
obstacles and build participatory systems across different food system stakeholders.
In addition to environmental and educational benefits, CPULs offer avenues for
generating income through food related business opportunities. The CPULs authors
propose that the main CPULs food production will occur on small to large crop fields
as per the unique CPULs fragment, which will be worked on by “local occupants who
rent the land and work on it commercially within an individually defined local
framework” (Viljoen et al., 2005, 12). This implies that CPULs can potentially offer
commercially viable business and job opportunities for local urban residents.
However CPULs face obstacles in implementation due to lack of sufficient
models documenting the widespread benefits of urban agriculture. Although there is
plenty of research and practical models demonstrating the life-cycle impact due to
embodied and operational energy in buildings (Viljoen, 1997, 1), “few studies have
examined the nature or recognition and integration of agriculture into regulative
frameworks for urban land-use” (Viljoen et al., 2005, 61). Consequently, there is lack
of documented models supporting the citywide application of urban agriculture and
CPULs that highlight benefits. Another major obstacle is that cost-benefit analysis of
land-use proposals tend to prioritize immediate economic benefit (Kaufman, Baikley,
2000, 54). Because of this, landowners tend to prioritize land-uses such as housing,
commerce and industry over agricultural use (Viljoen et al., 2005, 62). In order to
utilize land and infrastructure for urban food integration, cost-benefit analysis need to
expand to include environmental and socio-cultural benefits offered by CPULs.
56
In summary, CPULs ask the innovative question of developing continuous urban
rural traversing landscapes that are activated with agricultural productivity through
agriculture prototypes. It focuses on developing holistic goals that offer
environmental, social and economic benefits. Through providing environmental
benefits, CPULs advance the strategy of designing for the future. By implementing
urban agriculture into key institutions, CPULs help realize the design thinking tactic
of building participatory systems. As a result, the CPULs approach fulfills all the
steps in the design thinking framework.

Common Patterns and Obstacles in Implementation
From the analyzed past and current approaches that engage the food system,
Garden Cities and CPULs best excel at engaging the various design thinking
strategies and in developing holistic food systems. This is because the Garden Cities
concept has a well-developed social component of building participatory systems
between farmers and other professionals for local food system engagement.
57
Moreover, the Garden Cities design includes communal food preparation and dining
areas, through which food can be used as a tool for building social integration,
thereby further advancing participatory systems. The Garden Cities concept is also
well developed from the environmental sustainability perspective because it
elaborates on how urban waste and water can be recycled to provide fertilizer and
irrigation for local food production. The CPULs strategy advances the step of building
participatory systems by engaging key institutions with the food system. It also
provides environmental, economic and social benefits and advances holistic food
systems. Through providing environmental benefits, CPULs help in the advancing the
design thinking tactic of designing for the future. Both Garden Cities and CPULs
excel at engaging the design thinking strategies and developing holistic food systems.
However, these design approaches have limitations and face obstacles in
practical implementation (Kaufman, Baikley, 2000, 54):
•
Obstacles due to lack of visibility of successful models
•
Obstacles due to goals that prioritize economic returns and do not consider
environmental and social benefits
•
Obstacles due to lack of food system related skills
•
Lack of highlighting local food system benefits
•
Lack of government policy support
•
Lack of collaboration across non-profit and for-profit local food system
groups, institutional leaders and other key stakeholders

CHAPTER 5: UNIVERSITY FOOD SYSTEMS
The previous chapter analyzed past and current design approaches that engage the
food system. It also identified limitations and obstacles that current design approaches
face in practical implementation. This chapter explores the benefits of developing
sustainable university food systems that advance holistic goals. It goes on to discuss
the unique position of universities in overcoming obstacles faced by current design
approaches in practical implementation. Following this is a case study analysis of
university food systems: SEED Wayne at Wayne State University, Detroit, Michigan
and UMass Initiative at University of Massachusetts, Amherst, Massachusetts. These
case studies are analyzed in terms of how they engage the design thinking tactics and
implement components of current design approaches, thereby improving local food
access, community engagement, supporting local economic development, in order to
address contemporary food system issues.
Benefits in Developing Holistic University Food Systems
Universities have a unique role in developing holistic food systems for several
reasons. They are uniquely positioned for helping students develop healthy dietary
behaviors through “experiential learning” (Bartlett, 2011, 101), through theoretical
and applied inter-disciplinary research (Feenstra, 2002, 99) and through increasing
“institution-wide commitment to environmentally sustainable practices” (Horwitz,
2011, 142). Moreover, by creating healthy food environments, institutions have
potential to “influence and promote healthy dietary behaviors and to help ensure
appropriate nutrient intake” (Dietz, 2009, 1). In this way, universities can educate
students and staff about the broader environmental and social impact of food choices.
59
Given this influence, universities have the responsibility and opportunity for “building
the next generation of workers, citizens, and leaders, and [universities] need to take to
heart the dictum that healthy minds require healthy bodies, and ensure that healthy
food choices are available on their campuses” (Pothukuchi, 1999, 194).
Universities are also an active catalyst of inter-disciplinary research and
application by “integrating theoretical work with the applied and the pragmatic”
(Feenstra, 2002, 99). This makes universities the ideal experimental ground for
developing holistic food systems which require collaborations across various
disciplines such as nutrition, sociology, philosophy, economics, community
development, planning et cetera and which bring students and professors across the
campus together to offer interdisciplinary research and education (Pothukuchi, 2011,
194).
Along with supporting inter-disciplinary research, university food systems can
contribute to local economic development. Given a university’s institutional scale of
purchasing and marketing capacity, universities have potential to connect local
growers with eaters and make a significant contribution to their local economy. For
example, university initiatives such as on-campus food production, campus farmers
markets and local food procurement have potential to be utilized as strategies for local
economic development. Pothukuchi confirms that, “capturing even a fraction of these
dollars and targeting them toward local and regional producers through a campus
farmers market could make a significant difference” (2011, 194).
Finally, universities can bring both public and academic attention to the food
system through a variety of medias such as conferences, research papers, university
courses et cetera, thereby adding visibility to holistic food systems initiatives. This
visibility component is extremely important in institutionalizing current food system
60
initiatives and in ensuring their long-term implementation. Additionally, universities
have the commitment to the production of knowledge and many are also committed to
engaging partnerships with their community. Therefore, by building universitycommunity engagement, universities can potentially engage their larger community in
developing holistic food systems.
In order to better understand the role of universities in developing holistic food
systems, two university food systems are analyzed: Wayne State University and
University of Massachusetts as they are active in advancing holistic food systems and
their initiatives are well documented in journal articles, websites and documentaries.
Wayne State University, Detroit, MI
SEED Wayne is a model for collaboratively building sustainable food systems on
the university campus and in Detroit neighborhoods, through activities in teaching,
research, community engagement, and campus operations (Pothukuchi, 1). Kami
Pothukuchi who is an associate professor in the planning department at Wayne State
University founded it. The program has strong educational components as it actively
engages “students and others to examine the broader implications of their food
choices. It calls for a critical assessment of the problems posed by the industrial food
system to the health of local communities, economies, environments, and cultures,
even as it makes cheap food abundant” (Pothukuchi, 1). A primary goal of SEED
Wayne is to improve local food accessibility, actively engage the community and
utilize food as a tool for local economic development. The program’s activities
include on campus food production in gardens, rooftops, parking lot, food distribution
through cafeteria collaboration, campus weekly farmers market and food waste
61

management through cafeteria composting. In the surrounding community, SEED
Wayne helps with year round food production in a greenhouse and other urban farm
sites. It assists neighborhood corner stores to carry fresh fruits and vegetables. The
program is also involved with the Detroit Food Policy council to foster food security,
justice and sustainability by developing research, planning tools, policies and
programs (Pothukuchi, 1).
SEED Wayne improves local food accessibility through the Wayne State
Wednesday’s Farmers Market. Established in 2008, the market runs from the
beginning of June till the end of October, offering a range of farm-fresh produce,
herbs, flowers, honey and other freshly prepared foods from the city and the region
(Pothukuchi, 2013, 1). From the design thinking framework, the farmers market
serves as a model for building prototypes for testing alternative marketing of locally
grown food. Another SEED Wayne component that improves local food accessibility
is the Detroit FRESH project. The project helps connect local growers to
neighborhood corner stores. Through Detroit FRESH: The Healthy Cornerstone
Project, SEED Wayne canvases to the local community about the community’s
willingness to shop at the local grocery store and their shopping preferences. The
program communicates these findings with the neighborhood stores, provides
linkages to produce distributors, assists in marketing and communicates the store’s
capacity of carrying fresh foods back to the neighbors (Pothukuchi, 2013). In this
way, SEED Wayne helps in building local consumer-supplier partnerships and in
enriching the local economy. In an interview, Pothukuchi narrates her thoughts on
Detroit FRESH and its work with three pilot projects in which she has worked with
three corner stores:
63
These are mostly liquor stores to get them to carry more fruits and vegetables.
We did a lot of canvassing in the neighborhood and talked to them to see if
they’d be willing to shop for fruits and vegetables at the stores and then asked
them what they would like to see and then connected the store with the
distributor (Pothukuchi, 2013).
From the design thinking framework, the Detroit FRESH project also helps in
building participatory systems between food distributors and retailors The building of
participatory systems provides opportunities for community engagement. This is
applicable also to the Wayne State Wednesday farmers market, which is a “flagship
activity for SEED Wayne” and a platform for university-community engagement.
Pothukuchi shares that:
Farmers markets are so important for the community. They help connect
eaters with the sources of their food… Farmers markets are also great for a
neighborhood because they enliven a neighborhood and create all kinds of
buzz. They are like an event, a social event, people come by just to do people
watching, they’ll grab a snack and they’ll sit here for an hour at an end
(Pothukuchi, 2013).
Being the flagship activity, the market creates visibility for SEED Wayne within the
community. It also overcomes obstacles due to lack of food system related skills by
providing a variety of participatory opportunities such as interaction with local
growers, chef demonstrations et cetera. This further helps in building participatory
systems. Another component of community engagement is SEED Wayne’s university
lectures and student led workshops on various food sustainability issues. For example,
lectures held in Pothukuchi’s class, Cities and Food are open to the public and are a
medium for holding university-community based collaborative discussions where
community and nationally based food experts are invited to speak on sustainable food
system topics, thereby furthering the development of participatory systems.
64
Apart from improving local food access, local community engagement, SEED
Wayne utilizes food as a tool for local economic development. For example, the
farmers market connects local and regional food growers to university students and
community members who make up a large consumer population. By hosting the
farmers market, the university campus becomes a connecting platform between
growers and eaters. Moreover, strategies like supporting food stamps, such as SNAP,
ensures that growers and eaters derive full benefits for their dollar value. In
Pothukuchi’s words, “they (farmers markets) help generate what’s called a multiplier
effect, so that for every dollar that is spent in the market, 2 dollars actually get
generated because of the spin off that is created and it helps keep money in the local
economy, much better than a grocery store would” (Pothukuchi, 2013). Not only does
the campus farmers market target food dollars towards local growers and boost the
local economy, but it also helps in creating “green jobs” for the local community.
According to the 2010 economic assessment, Wayne State University’s Farmers
Markets put nearly $30,000 in the hands of local producers, $10,000 in food stamps
and $6,000 in the University’s Double Up Food Bucks Program through Fair Food
network (Pothukuchi, 2011, 196).
Along with local economic development, the farmers market provides
environmental benefits through local food sourcing. As mentioned earlier, locally
sourced foods travel much less to reach the eaters, thereby reducing food miles and
mitigating associated issues such as GHG emissions. Same applies for SEED
Wayne’s farmers market and the Farm to Cafeteria program that connects local
growers with on and off campus cafeterias. In addition to local food sourcing, SEED
Wayne also runs a cafeteria and residence halls composting project with the idea of
building a closed-loop food system and demonstrating a model where food wastes are
65
composted using a variety of methods and are coming back into the soil. The compost
is then used in fertilizing campus vegetable and herb gardens (Warrior Demonstration
Garden and St. Andrews Allotment Garden), which are worked on by student groups
along with staff who lease the plots seasonally to grow vegetables and herbs for their
own use or for distributing produce to food assistance sites (Pothukuchi, --). This
parallels with the agricultural urbanism approach of utilizing food as an economic
driver to build vertically integrated local food systems that are not only provide
economic resilience but are close looped and provide environmental benefits.
In summary, SEED Wayne improves local food accessibility, facilitates
community engagement and utilizes food as a tool for local economic development.
From the design thinking framework, SEED Wayne tests the alternative marketing of
local food through the farmers market prototype. It connects local food distributors to
retailors such as neighborhood corner stores through the Detroit FRESH: Healthy
Cornerstore Project, thereby building participatory systems. SEED Wayne’s
initiatives parallel agricultural urbanism through the creation of vertically integrated
closed loop food systems that are economically and environmentally beneficial.
University of Massachusetts, Amherst, MA
The University of Massachusetts’s UMass Permaculture initiative focuses on
improving local food accessibility, community engagement and local economic
development. The initiative was founded in 2010 by an interdisciplinary student-led
Permaculture Committee, described as “a group of passionate students that engage
and educate the campus community about permaculture and sustainability” (UMass
Permaculture, 1). The co-originator of the term permaculture defines it as as
66
Figure 21: Mapping UMass Initiative analysis. By author, 2015
67
“consciously designed landscapes which mimic the patterns and relationships found
in nature, while yielding an abundance of food, fiber and energy for provision of local
needs” (Holmgren, 2012, 3). In accordance with the definition, the UMass
Permaculture Initiative designed a “unique and cutting edge sustainability program
that transformed grass lawns on the campus into diverse, edible, low-maintenance,
and easily replicable gardens” (Geber, 2012, 1). This idea of converting under-utilized
spaces into agriculturally productive landscapes is similar to the design thinking
strategy of testing prototypes and the design of CPULs. On the university campus, the
initiative has transformed quarter acre of a grass lawn near the Franklin Dining
Commons into the Franklin Permaculture Garden, which now supplies food to UMass
dining services. Since 2010, the initiative has expanded into four on campus
permaculture gardens and two permaculture gardens at local elementary schools in the
surrounding community (UMass Permaculture, 1). Through the permaculture gardens,
the initiative increases local food accessibility and like CPULs, it also provides social
and educational benefits of engaging the local community. For example, 2500
students, staff across various disciplines and local community members have become
involved in the building of the permaculture gardens. From the design thinking
framework, community engagement has helped build participatory systems between
the university and the surrounding community.
Another component of the UMass Permaculture Initiative is how it is
“changing the way students interact with their food and surroundings” (UMass
Permaculture, 1). This connects back to CPULs which integrate food sustainability
into daily life with the intent of bringing about awareness towards environmental
impact of food. The UMass Permaculture Initiative serves as a vehicle for integrating
food sustainability as part of student campus life, with students reporting that they
68
come to volunteer at the garden between classes and the space has become a venue for
“empowering hands-on learning opportunities, beautiful gathering and an educational
space for volunteers, classes, groups, and community events”. Like the CPULs
strategy of building closed loop food systems, the UMass Permaculture Initiative
recycles UMass cardboard and woodchips to create 1.5 million pounds of compost
(UMass Permaculture Initiative, 1). This idea parallels the design thinking tactic of
designing for the future, which in this case means reducing the need for external
inputs and building closed loop food systems. This idea is similar to the CPULs
strategy of reducing embodied energy in food. Another components that reduces food
embodied energy is that since 2010, the UMass Residential Dining has made it a
“priority to source fresh, nutritious, local produce” (Horwitz, 2014, 1). The dining
service collaborates with a local farmer running “Czajkowski Farms”, a reliable and
consistent partner, who in turn expands his network to include other local farmers and
acts as a local aggregation and distribution center for UMass Residential Dining.
From the design thinking framework, this further facilitates community engagement
and the building of participatory systems across different local food system
stakeholders. Another component of community engagement that the UMass initiative
provides is the university’s Revisioning Sustainability Conference, that invites
“change-makers” nationally and internationally to re-envision food sustainability.
Along with improving local food accessibility and community engagement,
the UMass Initiative contributes to the local economy. The UMass dining has signed
on to the Real Food Challenge to commit to reaching 20% real food (which is locally
procured) in their overall food spending by 2020. As of 2013, UMass spent $1.8
million on Real Food which puts the university at an estimated 8% Real Food
(Lavallee, 2014, 1). This indirectly supports local economic development as
69
partnerships between local growers and the university help keep the dollars
circulating in the local economy.
In summary, the UMass Permaculture Initiative asks the innovative question
of converting under utilized grass lawns into agriculturally productive permaculture
gardens, both on campus and in the surrounding community. Through the design and
building of these gardens, the initiative builds participatory systems through
community engagement. These gardens supply produce to the UMass Dining
Services, thereby reducing the embodied energy in food. University cardboard and
other wastes are recycled as compost to fertilize these gardens, thereby further
minimizing embodied energy. The initiative helps real world food system issues by
mitigating chemical run off that pollutes water, depletes soil nutrients. These concepts
parallel the CPULs ideas of reducing embodied energy in food through the
development of closed loop food systems and through integrating experiences of food
sustainability into daily student life.

CHAPTER 6: CONCLUSIONS
This investigation began by considering the role of design in developing and
implementing holistic food systems. The discussion on industrial food system issues
in Chapter 2 revealed that the current food system prioritizes maximizing economic
efficiency and does not factor in environmental and social costs that are directly and
indirectly associated with the industrial food system. The complex and dynamic
nature of these environmental and social issues supported the case that food system
issues are wicked and need an innovative design approach for engaging them.
In order to investigate the role of design in developing and implementing
holistic food systems, a design thinking framework was developed in Chapter 3. The
various design thinking steps identified were: asking innovative questions, developing
holistic goals, building participatory systems, designing for the future and testing
prototypes.
This framework served as a matrix for analyzing past and current design
approaches that engage the food system. The analysis revealed that Ebenezer
Howard’s Garden Cities and Bohn and Viljoen’s CPULs were most effective in
engaging the various strategies in the design thinking framework and in developing
holistic food system goals. Howard’s Garden Cities utilized the strategy of asking the
insightful question of uniting the city with the country, developing participatory
systems between farmers and professionals and considering future upcycling by reusing urban waste and water as fertilizer in local food production. CPULs likewise
utilized the design thinking strategy of asking the innovative question of designing
continuous urban rural traversing landscapes that are activated by agricultural
productivity. CPULs also utilized the strategy of designing for the future by creating
closed loop food systems that convert urban waste into fertilizer. They developed
71
holistic goals for providing environmental, social and economic benefits and
emphasized food education in key institutions. The involvement of key institutions
with local food systems incorporated the design thinking strategy of building
participatory systems. Following this was an identification of obstacles faced by
current design approaches in implementing current design approaches.
In order to better understand the role of design in practical implementation of
holistic food systems, two university food systems were analyzed in Chapter 5:
Wayne State University, Detroit, Michigan and UMass Initiative at University of
Massachusetts, Amherst, Massachusetts. The analysis of Wayne State University
revealed that, like Agricultural Urbanism, SEED Wayne utilized food as a tool for
local economic and community engagement by for example, holding weekly farmers
markets and connecting surrounding corner stores with local growers. The analysis of
University of Massachusetts revealed that, like CPULs, the UMass initiative
converted vacant spaces into food production by, for example, converting underutilized grass lawns into permaculture gardens for food production. The UMass
initiative utilized the design thinking strategy of building participatory systems by
involving students across the university and community members in the building of
the permaculture gardens. UMass Dining further advanced participatory systems by
procuring food from local growers. These case studies demonstrate how holistic food
systems proposed by designers can be incorporated into contemporary reality, using
the various design thinking tactics to begin to address food system issues.
Limitations
While this study investigates many facets of design thinking as an approach to
addressing contemporary food system issues and the case studies present integrated
72
models of holistic food systems, this study is limited in two ways. First, it investigates
only three current design approaches to creating holistic food systems. There are
numerous permutations of these approaches as well as additional methods that were
not investigated. In addition, only two university food systems are analyzed. There are
many other universities and colleges that vary in scale and approach to local food
systems as well as other non-higher education situations that present holistic models
for local food system development.
Future directions
Based on the limitations listed above, future directions could involve the
analysis of more design approaches that engage the food system. Moreover, the study
could expand beyond university institutions and analyze other key institutions such as
elementary schools and hospitals to better understand their roles in overcoming
barriers and shifting the paradigm towards holistic food system goals and
implementation.
