Abstract
expansion of urban areas and establishing new agricultural lands in the vicinity of lakes have contributed to changes in land cover. The conversion of natural habitats into urban settlements and farmlands has led to the degradation and loss of wetland ecosystems surrounding the lakes. The most notable change in land cover is the shrinking of lakes due to the increasing water demands for irrigation and the gradual drying up of water bodies. El-Burullus Lake is one of the most important wetlands as they contain a rich biodiversity and many water bird species. This study aims to evaluate the change in land cover using three different scenes of satellite data from 2015 to 2023. Using Landsat 8, Landsat 9, and Sentinel-2 images for acquiring information about land use and land cover (LULC). Processing by GIS system and program ERDAS imagine. Accurate and frequent updates of surface water have been made possible by remote sensing technology. Index methods are mostly used for surface water estimation. Normalized Difference Vegetation Index (NDVI)and Normalized Difference Water Index (NDWI) are used to assess these area changes. Results indicated that vegetated land has increased significantly with a concomitant shrinkage in the water body and open soil during the study period. The study suggests the need for urgent attention on the conservation of remaining wetland resources for sustainable utilization for the next generation.
