Designing and Evaluating Urban Green Spaces for Climate Adaptation

Thesis Abstract

Urban areas are increasingly vulnerable to the impacts of climate change, including intense heatwaves, flooding, and declining air quality, necessitating the integration of sustainable and resilient urban infrastructure. This study aims to design and evaluate urban green spaces (UGS) as adaptive strategies for mitigating climate-related challenges in metropolitan settings. The specific objectives include assessing the current state of green space provision, identifying optimal design features for climate resilience, and evaluating the socio-ecological benefits of implemented green infrastructure. The research adopts a mixed-methods approach, combining quantitative spatial analysis with qualitative stakeholder perceptions to generate comprehensive insights. The study population comprises urban residents, local planners, and environmental experts within a mid-sized metropolitan area with a population of approximately 1.2 million residents, from which a stratified random sample of 400 residents and 30 key informants was selected. Data collection tools include Geographic Information System (GIS) mapping, structured questionnaires, interviews, and focus group discussions. Validity and reliability of the instruments were ensured through pilot testing, expert validation, and iterative refinement, with Cronbach's alpha exceeding 0.85 for survey items. Quantitative data are analyzed using regression analysis to determine the relationship between green space variables and microclimate parameters, while thematic analysis is employed to interpret qualitative responses. The conceptual framework integrates the Biophilic Design Theory, emphasizing the importance of human-nature connectivity, and the Social-Ecological Systems Theory, highlighting the interaction between ecological processes and social dynamics. The expected findings include identification of key design features—such as canopy cover, water features, and planting diversity—that significantly reduce urban heat islands and enhance flood resilience. Additionally, the study anticipates demonstrating a positive correlation between well-designed green spaces and residents’ perceptions of thermal comfort and environmental health. The research is expected to contribute new insights into the spatial configuration and socio-ecological functions of urban green infrastructure, filling existing gaps related to context-specific design guidelines and community engagement strategies. The findings will inform policymakers and urban planners on effective interventions for climate adaptation, emphasizing the integration of participatory planning processes with ecological design principles. The study concludes that strategically designed green spaces play a critical role in enhancing urban climate resilience and promoting sustainable city living. Based on these results, recommendations include adopting integrated green infrastructure planning at city-wide levels, prioritizing community involvement in green space design, and establishing monitoring frameworks to evaluate ongoing climatic benefits. Furthermore, the study advocates for incorporating climate resilience objectives into urban development policies and encourages further research on innovative green technologies and cost-benefit analyses of green infrastructure investments. Overall, this research advances theoretical understanding of climate-adaptive green space design and provides empirically grounded strategies for fostering resilient urban environments amidst climate uncertainties.
