Abstract

Urban neighborhoods are increasingly affected by climate-related stresses such as flooding, heatwaves, and deteriorating air quality challenges that traditional gray infrastructure alone cannot effectively address. This study investigates the role of green infrastructure (GI), including bioswales, green roofs, urban trees, and permeable pavements in enhancing climate resilience within dense urban environments. The research aims to evaluate both the environmental and social benefits of GI and to identify key factors that influence its successful implementation. A mixed-methods approach was employed, combining GIS-based spatial analysis, climate vulnerability assessments, and stakeholder interviews conducted in three climate-vulnerable neighborhoods in Cambridge, Massachusetts. Comparative case studies from cities such as Copenhagen and Portland were also analyzed to extract transferable strategies. Results indicate that neighborhoods with well-integrated GI systems experienced surface temperature reductions of up to 4°C, a 30–50% decrease in stormwater runoff, and increased local biodiversity. Additionally, residents in these areas reported greater satisfaction with their local environment and an improved sense of safety and well-being. Despite these benefits, several barriers were identified, including inconsistent maintenance, limited funding, and inequitable distribution of GI, especially in low-income communities. The study concludes that green infrastructure presents a viable and sustainable solution for enhancing urban climate resilience, provided it is supported by inclusive planning, policy integration, and long-term investment. Key recommendations include prioritizing GI implementation in underserved, high-risk areas; incorporating GI into zoning and land-use regulations; fostering community partnerships for ongoing maintenance; and utilizing spatial data tools to ensure equitable distribution and monitoring.
