<strong>Overview</strong> This dataset on trees covers Dublin City, Ireland. It indicates the locations of over 300,000 trees which were acquired using a point-and-click methodology using a high-quality aerial image (resolution of 12.5 cm) taken in June 2018. Each x,y location represents the tree canopy centre. The database also includes the estimated height of these trees based on a Digital Elevation Model (horizontal resolution of 1m, vertical resolution *m). This information is complemented with detailed information on individual trees, where available. This includes, for example, data on 2440 street trees (species and dimensions) gathered in 2008/2009. The dataset will be updated at regular intervals as information on individual trees is acquired. <em>* to be updated</em> <strong>Purpose</strong> Information on trees (location, species, age, and health) in urban areas is needed to assess the green infrastructure and the ecosystem, environmental and social services that they provide. These data were acquired to support greening strategies and actions in the Dublin City Council area. <em>Additional comments</em> The creation of the Dublin tree database was supported in part by a research grant from Ireland's Environmental Protection Agency (EPA) and using databases acquired by the School of Geography at UCD. The tree database is part of the Mapping Green Dublin project and is being used by the Curio app, which allows citizens to add data on individual trees.

Concerns for environmental quality and its impact on people’s welfare are fundamental arguments for the adoption of environmental legislation in most countries. In this paper, we analyse the relationship between air quality and subjective well-being in Europe. We use a unique dataset that merges three waves of the European Social Survey with a new dataset on environmental quality including SO2 concentrations and climate in Europe at the regional level. We find a robust negative impact of SO2 concentrations on self-reported life satisfaction.

One of the great challenges in urban climate research is to transfer the results of this work to planning and design practitioners. In order to handle the complexity of the urban environment much research was carried out using very simple configurations (e.g. symmetrical street canyons). However, such experimental work often requires specialized knowledge and often has little obvious correspondence to real-city environments. Ideally, urban climate knowledge could be integrated into the working context of these practitioners. This is most effectively done through an urban GIS model where the planner's local knowledge of places can be linked with environmental quality. Recent advances in both the availability of urban 3-D data and in GIS software could provide this link. For example, detailed building topography allows us to estimate variables such as solar access and sky-view factors, which exert considerable influence on micro-scale climates, on a city scale.

Poor air quality is a pervasive problem in cities and is associated with a suite of air pollutants that include gases and particulate matter (PM). Managing the concentration of these pollutants in the atmosphere near the ground is the objective of air quality management plans that compare measured values against health guideline values to design policy responses. However, the spatial and temporal variation in pollutant concentrations can be very large such that values measured at a fixed station may have little relevance to specific urban environments. This work examines the distribution of PM near roads in Dublin using the materials that accumulate on the leaves of nearby trees measured using saturation isothermal remenant magnetization (SIRM). Following a dry period from 25th to 28th June, 2013, approximately 200 leaves of street trees of a variety of species were collected in Dublin; these were picked at head height, from locations with varying traffic densities and land use cate...

Communication is the lifeline to progress in any civilization and can be expressed verbally, literally, numerically or graphically. Graphic communication involves the use of symbology, via signs and symbols to convey messages to enhance visualization. In Papua New Guinea (PNG) the main form of communication before colonization (just before the First World War) was verbal or by “word-of-mouth”. Verbal cartographic communication has been the norm and many societies describe metes and bounds or make references verbally. ...

Particulate matter (PM) deposited on Platanus acerifolia tree leaves has been sampled in the urban areas of 28 European cities, over 20 countries, with the aim of testing leaf deposited particles as indicator of atmospheric PM concentration and composition. Leaves have been collected close to streets characterised by heavy traffic and within urban parks. Leaf surface density, dimensions, and elemental composition of leaf deposited particles have been compared with leaf magnetic content, and discussed in connection with air quality data. The PM quantity and size were mainly dependent on the regional background concentration of particles, while the percentage of iron-based particles emerged as a clear marker of traffic-related pollution in most of the sites. This indicates that Platanus acerifolia is highly suitable to be used in atmospheric PM monitoring studies and that morphological and elemental characteristics of leaf deposited particles, joined with the leaf magnetic content, ma...

Urban areas profoundly alter the local atmosphere, hydrology and biology, usually for the worse. Increasing the vegetative cover in urbanised areas is considered an effective way of offsetting many of the undesirable outcomes of urbanisation and is often incorporated as Green Infrastructure into urban development plans. In this paper we present a first assessment of the green cover in Irish city centres (Belfast, Cork, Derry, Dublin, Galway, Limerick and Waterford) and evaluate the environmental benefits of trees for air quality using the i-Tree Canopy software. This online software is used to conduct a spatial sample of the urban landscape and estimate tree canopy cover from which potential air quality benefits are calculated. The results show significant differences between and within city centre areas in terms of vegetative (and tree) cover; Belfast and Dublin, with less than 10% vegetative cover are in marked contrast to other cities where the average is close to 30%. Based on t...

Communication is the lifeline to progress in any civilization and can be expressed verbally, literally, numerically or graphically. Graphic communication involves the use of symbology, via signs and symbols to convey messages to enhance visualization. In Papua New Guinea (PNG) the main form of communication before colonization (just before the First World War) was verbal or by “word-of-mouth”. Verbal cartographic communication has been the norm and many societies describe metes and bounds or make references verbally. The receiver or map-user stores the verbal message as visualized temporal mental map and executes the instructions. The present generation in PNG is in a period of transition between the old and the new systems of communication. This paper emphasizes the importance of graphic communication in PNG. Traditional methods of space perception are discussed. Current status in general cartographic communication, cartographic institutions, their functions and datasets available ...

The relation between human population growth and land use change is much debated. Here we present a case study from Papua New Guinea where the population has increased from 2.3 million in 1975 to 5.2 million in 2000. Since 85% of the population relies on subsistence agriculture, population growth affects agricultural land use. We assessed land use change in the Morobe province (33,933 km2) using topographic maps of 1975 and Landsat TM images of 1990 and 2000. Between 1975 and 2000, agricultural land use increased by 58% and population grew by 99%. Most new agricultural land was taken from primary forest and the forest area decreased from 9.8 ha person(-1) in 1975 to 4.4 ha person(-1) in 2000. Total population change and total land use change were strongly correlated. Most of the agricultural land use change occurred on Inceptisols in areas with high rainfall (>2500 mm year(-1)) on moderate to very steep slopes (10-56%). Agricultural land use changes in logged-over areas were in the vicinity of populated places (villages), and in close proximity to road access. There was considerable variation between the districts but districts with higher population growth also had larger increases in agricultural areas. It is concluded that in the absence of improved farming systems the current trend of increased agriculture with rapid population growth is likely to continue.

Air quality can be an important contributory factor to individuals’ wellbeing.  Analysis of European Social Survey (ESS) data finds a significant negative relationship between regional concentrations of sulphur dioxide (SO2) in the atmosphere and life satisfaction across Europe.

Several European countries are currently undertaking fundamental revisions of their energy
policies. Many of these activities are motivated by concerns about environmental
sustainability (in particular with respect to climate change), energy security (in particular in
relation to import dependence), energy costs (in particular the costs and prices of electricity),
and nuclear safety (in particular after the nuclear disaster at Fukushima, Japan).
The project entitled “Using Subjective Well-Being Data for Energy Policy Analysis – Energy
for Well-Being” aims at an assessment of such concerns in terms of citizens’ individual
welfare or utility. The specific approach pursued in this project is to operationalize utility as
subjective well-being (SWB) or ‘happiness’. The encompassing question is what utility people
derive from energy. More specific research questions include the following: How do the costs
of energy consumption affect SWB? What are citizens’ preferences for alternative
configurations of the energy supply system in terms of SWB? What are the consequences for
SWB of living close to energy facilities? Are there effects of the Fukushima accident on
European/Swiss citizens’ SWB? The project has addressed such questions by means of
SWB regressions with energy costs and parameters of the energy system as independent
variables. It has used Geographic Information Systems (GIS) to combine regionally
disaggregated micro data from five rounds of the European Social Survey (ESS) and the
Swiss Statistics on Income and Living Conditions (SILC) with data on energy prices, the
energy mix, and the location of energy facilities from the International Energy Agency (IEA)
and the International Atomic Energy Agency (IAEA). It was found that citizens’ SWB is
systematically and significantly related that energy prices, the energy mix, the proximity to
energy facilities and that the relationship between SWB and the electricity mix changed at
the time of the Fukushima nuclear accident.

street trees of a variety of species were collected in Dublin; these were picked at head height, from
locations with varying traffic densities and land use categories, after a dry weather, on weekdays during
growing season. The highest SIRM values observed were on trees that line busy streets with high traffic
densities and at traffic intersections. The results show the potential for trees to act as filters, screening
pedestrians from busy roads and that bio-magnetic monitoring can provide data at a high temporal and
spatial resolution at low cost.

While urban areas are often considered to be comprised chiefly of artificial surfaces, they can contain a substantial portion of green space and a great diversity of natural habitats. These spaces include public parks, private gardens and street trees, all of which can provide valuable environmental services, such as improved air quality. Trees play a particular role in cities as they are often placed along roadsides and in the median strip of busy streets. As such they regulate access to sunshine, restrict airflow, provide shelter, scavenge air pollutants and manage noise at the street level. A tree planting policy can be an important part of a broader environmental strategy aimed at improving the quality of life in urban areas but this requires up-to-date knowledge of the current tree stock, which does not exist for Dublin. This article presents an inventory of trees in Dublin’s city centre, defined as the area between the Grand and Royal canals. The results show that there are over 10,000 trees in the study area representing a density of 684 trees km
2 or one tree to approximately every 50 residents of the city centre. The tree canopy extent when in full foliage was nearly 1 km2 in extent or 6% of the study area. A more detailed analysis of those trees planted along streets shows little species variation but clear distinction in the sizes of trees, which is indicative of the age of planting. These data are used to estimate the carbon stored in Dublin’s trees.
