This manuscript presents a multidisciplinary study that proposes a methodology for delineating and categorizing vulnerability at rockfall risk areas to avoid human injuries and infrastructure damage caused by rockfalls. The presented workflow includes (i) classical geological mapping, (ii) the interpretation of high-resolution satellite data for observing the spatial distribution of fallen boulders, (iii) analytical hierarchy processing of spatial information within a Geographical Information System (GIS) platform, (iv) close-range remote sensing campaigns with Unmanned Aerial Systems (UASs), and (v) integrated simulation of rockfall events. This methodology was applied to Kalymnos Island, which belongs to the Dodecanese Islands complex of the southeastern Aegean Sea in Greece. It is characterized by unique geomorphological features, including extensive vertical limestone cliffs that span the island. These cliffs make it one of the world’s most densely concentrated areas for sport climbing. The results highlighted the areas that the local authorities need to focus on and suggested measures for increasing the safety of climbers and infrastructure. Full article

Improving geo-information decision evaluation is an important part of geospatial decision support research, particularly when considering vulnerability, risk, resilience, and sustainability (V-R-R-S) of urban land–water systems (ULWSs). Previous research enumerated a collection of V-R-R-S conceptual component commonalties and differences resulting in a synthesis concept called VRRSability. As a single concept, VRRSability enhances our understanding of the relationships within and among V-R-R-S. This paper reports research that extends and deepens the VRRSability synthesis by elucidating relationships among the V-R-R-S concepts, and organizes them into a VRRSability conceptual framework meant to guide operationalization within decision support systems. The core relationship within the VRRSability framework is ‘functional performance’, which couples land and water concerns within complex ULWS. Using functional performance, we elucidate other significant conceptual relationships, e.g., scale, scenarios and social knowledge, among others. A narrative about the functional performance of green stormwater infrastructure as part of a ULWS offers a practical application of the conceptual framework. VRRSability decision evaluation trade-offs among land and water emerge through the narrative, particularly how land cover influences water flow, which in turn influences water quality. The discussion includes trade-offs along risk–resilience and vulnerability–sustainability dimensions as key aspects of functional performance. Conclusions include knowledge contributions about a VRRSability conceptual framework and the next steps for operationalization within decision support systems using artificial intelligence.

This study proposes planning for children’s independent mobility through geoinformation technologies by listening to children. This research assumes that children’s values and expectations must be considered in city planning. A bibliographic review identified 15 indicators which make spaces safe and attractive for children to circulate and play. Thematic maps of the indicators were prepared and integrated by a multicriteria analysis by the weights of the evidence according to the hierarchical importance of each variable. The definition of the weights considered the opinions of the children and technicians. The consultation with children was carried out by mapping volunteers (VGI), a consultation on hierarchy, the geodesign of ideas for the area, and an artistic workshop. In the technical study, the query applied the Delphi method. It used the VGI—Volunteered Geographic Information—web-based platform, where children recorded places of topophilia and topophobia, while technicians mapped the presence of 15 indicators. The set of information was made available on a web-based platform called SDI—Spatial Data Infrastructure—in which there are resources for a geodesign workshop where ideas for the area were elaborated through negotiation and cocreation. The product is a transformational design for the area through urban design and the parameterization of its uses. Full article

The need for addressing the adverse impacts of transport infrastructure on public spaces and human activities (TSH) emphasizes the importance of designing integrated TSH system, thereby necessitating tailored planning support systems (PSS). This study begins by assessing the demand for PSS using surveys and interviews to uncover the need for robust analysis and evaluation support, particularly through the use of geographical information systems (GIS). On this basis, a prototype GIS platform is proposed for analyzing and evaluating the integration of the TSH system at the block scale. This user-friendly geodesign tool encompasses a customizable evaluation index (includes seven KPAs and KPIs), allowing for combined quantitative and qualitative assessments. Notably, it introduces a buffer effect index to quantify transport–space interaction. The proposed tool serves as a dedicated platform for evaluating TSH systems, offering 2D/3D visualization capabilities and two analysis units and facilitating cross-platform collaboration. Applied to a case study in Nanjing, China, it effectively assessed the interdependence among different TSH system components and block integration around expressways, railways, and main roads. This tool holds promise in offering invaluable insights into urban planning and (re)development, thereby enhancing the integration of transport infrastructure and public spaces. Full article

Water-sensitive urban design (WSUD) is a subset of nature-based solutions (NbSs) that are implemented worldwide. However, the WSUD guidelines in some local contexts, such as Southeast Asia, remain unclear both for ecological and cultural reasons. This study aims to gather collaborations between researchers, designers, and laypeople in WSUD, which have the potential to be implemented to address water quality issues. The study consisted of three stages: site selection, a design workshop, and public interviews. Utilizing geo-design principles and geographical data, the potential pilot site was identified: a vacant space next to the Tha Phae Gate Plaza. A two-day workshop with landscape design experts yielded six conceptual designs, focusing on diverse themes such as water treatment, plant-based solutions, educational opportunities, and cultural enrichment. Public interviews provided insights into the community’s perspectives on stormwater management, desired amenities, environmental considerations, and governance concerns. The results highlighted a collective interest in using NbSs for stormwater treatment and enhancing the area’s recreational and educational potential. This study offers a comprehensive approach to addressing water quality issues in urban settings while considering local cultural, recreational, and environmental needs. Full article

The sense of place is a multidimensional construct that evokes an emotional commitment to a specific geographic setting. It can be a crucial aspect of cultural ecosystem services. While social media has gained popularity as a tool for assessing ecosystem services, its effectiveness in capturing a sense of place, its impact on cultural ecosystem services, and its role in the landscape design process remains less certain. This study investigates the role of urban parks in shaping the sense of place by analyzing user-generated content from a specific social media platform (Twitter). We gathered tweets from 30 diverse urban parks in Chicago, covering various park types, sizes, shapes, and management styles. Our analysis reveals multiple facets of the sense of place associated with urban parks. We suggest that a sense of place is not solely rooted in the attachment to physical surroundings but also in the personal experiences individuals encounter within these spaces. Residents residing near parks tend to develop a sense of ownership and responsibility, leading to stronger emotional bonds with their environment. Urban parks foster community engagement, enhance social cohesion, and offer opportunities for nature-based experiences. Furthermore, this study underscores the significance of diverse park features, accessibility, and size in bolstering place attachment. Our research demonstrates the potential for geoinformation analysis in the geodesign process as a cost-effective and scalable approach for understanding the person–place connection. Full article

Resilient cities have emerged as novel urban ecosystems that respond to the increasing challenges of contemporary urban development. A new methodological approach is needed to measure and assess the degree of resilience of the urban landscape during the ongoing planning process, considering different planning and design scenarios. Based on this consideration, the first attempt of this study was to develop a resilience index that summarizes the application of resilience theory in urban landscape planning. Is geodesign an appropriate tool to assess urban resilience? This was the main research question and the topic of the workshop ’’IGC—Resilient City of Belgrade’’ at the Faculty of Forestry, University of Belgrade (Master Landscape Studio). The main result of this research is a model for urban resilience assessment with IGC geodesign, which allows to measure scenario changes through developed resilience indicators (index), which are determined by a set of parameters (area, redundancy, diversity, porosity, carbon sequestration, edge type, edge length, etc.). The methodological approach allows quantifying the impact of adopted innovations in geodesign scenario proposals, which plays a crucial role in strengthening the connection between landscape planning and design. In the context of the novel urban ecosystem, future urban landscape planning should focus on resilience as a measure to achieve sustainable development goals, supported by geodesign as a collaborative and spatially explicit negotiation tool.

Urban growth models are increasingly being used to generate scenarios within city and regional planning support systems (PSS). However, their usefulness in land use planning applications, particularly in city resilience planning, is not fully understood. Thus, we developed a cellular automata model using Metronamica PSS for the Greater Sydney region and assessed its usefulness as perceived by planning and policy practitioners. The study was implemented through a collaborative geodesign workshop where participants (n = 19) were guided to an understanding of the modelling process and to create and validate alternative policy scenarios for 2050 that reflected Business-As-Usual, Bushfire resilience, Flood resilience, and Combined resilience. We conducted two surveys and a SWOT analysis to assess the usefulness of the PSS and its outputs. We found that the PSS created credible scenarios using collaborative inputs from the participants. The PSS had perceived value for informing participants about land use changes in the resilience planning contexts with high flexibility and granularity. The plausibility of the scenario outputs, a usefulness parameter, was readily accepted, but the model’s transparency (another parameter) was seen as potentially inhibiting application in real-world planning. Future research should involve a broader audience, including the local community, in analysing the usefulness of PSS. Full article

Around the world, human populations and their supporting infrastructures are concentrated in coastal areas. With rising sea levels, these settlements and urban infrastructures are at risk of service interruptions, lasting damage and frequent climate-related hazards. Wastewater systems are especially vulnerable due to their proximity to coastlines. Despite the seriousness of sea-level-rise-induced challenges, a clear understanding of the risks and potential adaptations of coastal wastewater treatment systems and their associated landscapes in Australia has been overlooked. Further, there is a lack of urgency and awareness concerning this issue. In this study, we consider how scenario-based landscape design approaches might enhance current debates and approaches related to coastal change with particular reference to wastewater treatment systems and associated environmental landscapes. Adelaide is used as a case study, and a range of landscape planning exploratory scenarios are developed and evaluated to assess the possible consequences of different courses of action in uncertain contexts. We find that whilst wastewater treatment plants are threatened by climate-related hazards, there is an opportunity for landscape-scale environmental planning to manage risks and opportunities and improve ecological and economic outcomes. We also find that for wicked multidimensional problems, such as sea level rise, landscape scenario design testing can assist in identifying a number of creative adaptation approaches that are not immediately apparent. We find that approaches such as retreat, defense and accommodation are not mutually exclusive but can each share elements and strategies. The strategic potential of a more creative, scenario-based approach can therefore form a productive part of the sea level rise adaptation of coastal infrastructure landscapes in Australia and elsewhere.

As growth in the western U.S. continues to lead to the development of land, pressure is being exerted on agricultural production, and could lead to the loss of prime agricultural land. A wide array of perspectives concerning agricultural protection requires a variety of possible solutions. Diverse and plausible scenarios, driven by stakeholders, can be modeled by researchers to guide potential solutions to address key challenges within a region. This paper addresses one stakeholder-defined social-ecological system (SES) solution in the context of southern Idaho, one of the fastest-growing states in the U.S.: agricultural protection zoning. This project demonstrates a method for incorporating an Agriculture Protection Zone (APZ) within a suite of scenarios showing land protection opportunities across a range of future conditions and challenges. The results, by way of a Geodesign framework, entail suitability analyses through a series of weighted raster overlays to analyze scenario-based solutions. The suite of scenario solutions was compared to demonstrate effective proportions of the APZ. The analysis of the results, as a solution gradient, aim to inform policy makers, planners, and developers about the efficiencies of various APZ delineations as well as a methodology to demonstrate the impact of solutions based on assumptions of stakeholder-informed future scenarios.

Although geodesign techniques have been studied and developed worldwide, there is still a lack of in-depth application of geodesign workflows for redesigning urban river wetlands with characteristics of ecologically engineered landscaping (EEL). The study mainly aims at putting forward a proper approach in the methodological foundation for EEL practices in river wetlands. A typical EEL-oriented project of river restoration in Hangzhou, China, was conducted in this study. Based on in-situ geodata and tools within QGIS, individual geological factors analysis, with the hierarchical analysis method (AHP) and ecological vulnerability evaluation (EVE), was conducted by experts’ voting and the weighted linear combination (WLC) method. Analysis of hydrological-related factors proceeded. This GIS-based analysis with expert knowledge provided comprehensive redesign solutions for the redesign project, i.e., restoration of the riverbed, spatial restoration in the horizontal and vertical dimensions, and integration with the multifunctional design. Detailed three-dimensional models for design practices were developed to present redesigned topology and space accordingly. Terrain, inundation, and visibility analysis proceeded with parametric mapping programs within Grasshopper to check the feasibility. The adapted geodesign-based workflow in the study also applies to the site analysis, sustainable assessment and landscape planning for urban wetlands EEL projects. Full article

Hostplant limitation is a key focus of the spatial interaction between a phytophagous butterfly and a hostplant. The possible drivers related to the hostplants are species richness, abundance, or availability, but no consensus has been reached. In this study, we investigated the butterfly–hostplant interaction using the case of the forest canopy butterfly T. aureus in Asia, whose narrow distribution is assumed to be limited by its exclusive hostplant, Magnoliaceae, in tropic and subtropic regions. We recorded the Magnoliaceae species, as well as plant and butterfly individuals in transect, and we collected tree traits and topography variables. The results confirm that this butterfly is limited by the hostplants of their larval stage. The hostplants occurred exclusively in the middle-mountain region, with preference only for primeval forests. The hostplant resource was superior in the middle-mountain region, particularly concentrating in primeval forests. The hostplant’s abundance, together with altitude and habitat types, was critical to this butterfly’s occurrence, while those hostplant trees with an exposed crown, which are demanded by this butterfly in its oviposition, were the best drivers of positive butterfly–hostplant interactions. Therefore, the hostplant’s limitation was mainly determined by the availability of the hostplant. This case study supports the hypothesis that the limitation on this butterfly’s occurrence was driven by the hostplant’s availability, and it suggests that protecting high-quality forests is a valuable activity and essential in the conservation of canopy butterflies.

In recent times, cities have increasingly promoted bicycling as a mode of transport as part of their strategy to develop a more sustainable transportation system. Australia is one of the countries that seeks to promote bicycling in a significant manner. There are two primary barriers faced in this effort. The first is the organizational complexity of planning and of implementing cycling-related projects, which can span across different agencies in government at various levels, from federal to local. Second is the lack of a clear framework for effectively planning a bicycling network using multiple data and tools available to these agencies within a limited budget. This study investigates the use of a geo-design-based, collaborative, and data-driven framework for planning bicycling networks, which brings various stakeholders, such as transport planners, urban designers, and academics, into the planning practice, thus overcoming the mentioned barriers. Geo-design is an environmental design framework for complex problems involving the collaboration of different teams and stakeholders, supported by digital computing and communication technologies. To the best of our knowledge, there is no study in the literature applying the geo-design approach for bicycling planning. Therefore, this study aims to develop and test a geo-design framework for planning bicycling networks to examine possible design scenarios and facilitate decision-making processes. In this regard, this study developed a geo-design framework for planning for bicycling using various bicycling-related datasets and digital tools, such as the Agent-Based Model. Then, it applied the framework to design a real-world bicycle network through a geo-design workshop while examining the usefulness and effectiveness of the developed procedures and tools. Policymakers attended the geo-design workshop from the local government authority of the case study area, Penrith, and post-graduate level urban planning students from UNSW. Due to COVID-19-related restrictions, the workshop was held in a hybrid format, with half of the participants joining online. The results of this study revealed that by facilitating collaboration and applying data-driven approaches, the proposed geo-design bicycling framework could improve the process of planning for bicycling infrastructure. This study also enabled the research team to understand the strengths and limitations of the developed framework and associated tools, which will help to optimize them for other planning practices in the future.
