The Role of Urban Green Spaces in Mitigating the Urban Heat Island Effect: A Case Study of Metropolitan Cities in India
Urbanization has led to significant alterations in natural landscapes, resulting in the emergence of urban heat islands (UHIs), where urban areas exhibit substantially higher temperatures than surrounding rural environments. This phenomenon contributes to increased energy consumption, air pollution, and health risks for urban populations. In response, urban green spaces—parks, gardens, and urban forests—have been recognized as an effective, nature-based solution to combat the adverse impacts of UHIs. This study investigates the role of urban green spaces in mitigating UHIs within five major metropolitan cities of India: Delhi, Mumbai, Kolkata, Bengaluru, and Chennai.
Using a combination of remote sensing data, geographic information systems (GIS), and on-ground temperature monitoring, this research analyzes the spatial distribution of green spaces and correlates them with land surface temperatures. The study finds a strong inverse relationship between the density of urban vegetation and the intensity of the UHI effect. Areas with higher tree canopy cover exhibit surface temperatures 2–4°C lower than adjacent non-green zones during peak summer months. Furthermore, the cooling effect is found to extend beyond the boundaries of the green spaces, providing benefits to surrounding urban neighborhoods.
The findings highlight the critical importance of incorporating green infrastructure into urban planning strategies to enhance thermal comfort and reduce energy demands in tropical megacities. Moreover, this research emphasizes the need for policy frameworks that prioritize the preservation and expansion of urban green spaces as a cost-effective and sustainable approach to climate adaptation. In conclusion, this study contributes to the growing body of evidence supporting the multifunctional benefits of urban nature in building resilient and livable cities amid accelerating climate change.
