Spatiotemporal Analysis Land Use Land cover changes in South Kashmir Region of North-western Himalayas Using Landsat data

Abstract

Abstract This paper presents a comprehensive analysis of land use changes in South Kashmir from 2000 to 2022, revealing significant transformations in various land cover classes. Leveraging remote sensing and geographic information systems (GIS), the study examines the spatial patterns and temporal dynamics of land use and land cover, offering valuable insights into the region's landscape dynamics. Using supervised classification techniques, satellite imagery was analyzed to identify 10 major land use classes. The findings demonstrate notable increases in horticulture and built-up areas, accompanied by declines in agricultural land, glaciers and snow, exposed rock, and water bodies. The expansion of horticultural lands, covering approximately 7% of the study area, has been attributed to the conversion of agricultural lands. This shift, coupled with the encroachment of settlements to accommodate the growing human population, has resulted in a substantial loss of approximately 757 km2 of farmland agriculture, representing a total percentage change of about 13% during the study period. The implications of these changes extend beyond the local region, highlighting the urgent need for comprehensive and sustainable solutions to address human-induced challenges at a global scale. Furthermore, the study underscores the cost-effectiveness and efficacy of geospatial technologies in conducting spatiotemporal analyses and formulating evidence-based policies for the sustainable management of natural resources. The insights gained from this study offer a solid foundation for informed decision-making and the development of targeted land management strategies in South Kashmir and other similar regions facing similar challenges.
