Abstract

New trends in wetland management, analysis, and conservation are based on remote sensing techniques and geographical information systems (GIS).Present study investigates the LULC (land use land cover) analysis of Okhla Bird Sanctuary, with the help of LISS III (2008) and Sentinel-2 (2021)satellite data. A comparison study involving all three categories (water, barren land, and vegetation) has been carried out as part of the process of monitoring the change in land use and land cover. From 2008 to 2021, there were big changes in the barren land, which grew by 50.77%, and in the amount of vegetation cover, which went down by 36.87%. The results of regression analysis indicate that LULC classes was influenced by precipitation, 88.7% in 2008 and 64.9% in 2021.Wetlands are one ecosystem where governments around the world should focus their attention to help recharge groundwater and control the amount of water, which will also help solve the problem of drinking water scarcity.
