Urban green spaces (UGSs) are integral to urban planning and impact various facets of urban quality of life.

This study utilizes geospatial techniques to analyze green equity through analyzing the distribution of UGSs in built areas of a city in India.

Technical tools such as remote sensing and geographic information systems (GIS) are used to map and analyze the availability of UGSs at various spatial scales, which may then be employed successfully in urban planning.

The intra-city evaluation of the distribution of green spaces at the ward level and availability in built form is used to measure the equitable distribution of UGSs.

摘要

Urban green spaces (UGSs) are integral to urban planning and impact various facets of urban quality of life. However, the distribution and governance of urban vegetation are inequitable in many cities worldwide. This study utilizes geospatial techniques to analyze green equity through analyzing the distribution of UGSs in built areas of a city in India. The urgency of this research is underscored by the inequitable distribution of UGSs. Technical tools such as remote sensing and geographic information systems (GIS) are used to map and analyze the availability of UGSs at various spatial scales, which may then be employed successfully in urban planning. Further indices like the normalized difference vegetation index (NDVI) are used to identify the ratio of the vegetated surface to non-vegetated surface in urban areas. The intra-city evaluation of the distribution of green spaces at the ward level and availability in built form is used to measure the equitable distribution of UGSs. Based on the above, critical wards that need immediate interventions are identified. The study confirms the use of robust geospatial techniques for planning recommendations for creating justifiable green spaces in urban areas.
