Abstract

For effective natural resource planning and management, land use/land cover change is necessary. The current study is an effort to identify changes in LULC in district Ziarat through Temporal and spatial extents. This research was carried out using Geographic Information Systems (GIS) and Remote Sensing (RS). The official USGS website was used to collect three LANDSAT satellite images. These are LANDSAT-7 and LANDSAT-8 satellites.  The data were collected for the years 2002, 2012, and 2022. ArcMap 10.8 was used to examine satellite images, and maximum likelihood supervised image classification was utilized to find the LULC. Results showed that the barren land increased by 3.2%, vegetation decreased by -4.2%, the built-up area increased by 1.4% and water bodies decreased by -04%. The increase in barren land and built-up regions in the research area was attributed to the loss of vegetation. This study highlighted changes that have occurred in the district of Ziarat during the past 20 years, it is crucial for future planning in the study area. Responsible authorities must have jurisdiction over deforestation and tree cutting for the construction of homes and burning. To prevent the water bodies in the research area from shrinking, the competent authorities must build minor storage dams and set up contemporary water supply systems.
