Identification of Multipurpose Greenway Networks for Ecological Resilience Using Geospatial Technology: Case Study of South Delhi District in India

Urban greenways counter ecological fragmentation and enhance urban sustainability. This study proposes a multipurpose greenway network in South Delhi District to improve ecological connectivity and urban liveability amidst rapid urbanization. Key areas such as Asola Bhatti Wildlife Sanctuary, Hauz Khas, and Saket were identified using geospatial analysis, considering factors like land availability, road density, protected areas, demand, and topography through a Rating and Weighting (RAW) method. The findings reveal the potential of greenways to connect fragmented green spaces, integrate recreational zones, and preserve natural habitats while linking cultural and historical landmarks. Comparative analysis with greenway projects in Bangalore and Singapore highlights scalability and best practices. Bangalore’s initiatives focus on linking urban lakes and parks, showcasing the use of local ecological features as anchors. Singapore’s Park Connector Network demonstrates the benefits of cohesive urban ecosystems. These examples emphasize the importance of phased implementation and institutional support for success. The proposed greenways not only enhance biodiversity but also mitigate urban heat islands, improve air quality, and promote public health through accessible recreational spaces. Policymakers and urban planners can adopt this model to address environmental challenges, improve urban liveability, and drive sustainable development in other urbanizing regions. The research underscores greenways as a blueprint for creating ecologically and socially resilient urban environments.
