Green Cover Assessment of Delhi National Capital Territory of India

This study conducts a comprehensive assessment of the green cover in the Delhi National Capital Territory (NCT) of India through advanced remote sensing techniques, utilizing the Normalized Difference Vegetation Index (NDVI) derived from high-resolution Sentinel-2 satellite imagery. The methodology involved the preprocessing of multispectral satellite data to accurately compute NDVI values, enabling detailed mapping and quantification of vegetation density across the region. To ensure the robustness of the analysis, the NDVI-derived vegetation metrics were cross-validated against data from the India State of Forest Report 2021 (ISFR), an authoritative source provided by a Government of India agency. The temporal analysis revealed a significant increase in green cover from 2019 to 2022, followed by a marginal decline in subsequent years, highlighting the dynamic nature of urban green spaces. The integration of remote sensing technology and geospatial analysis in this research underscores the potential of quantitative methods in environmental monitoring, offering critical insights into urban ecosystem management and policy formulation.
