摘要

Globally, land cover change poses a serious threat to biodiversity and climate change. Anthropogenic actions have been the dominant force among all natural and human forces shaping the Land use and Land cover, causing dramatic changes to the global Landuse and Land cover. The Rajparian Wildlife Sanctuary in the Kashmir Himalayas has undergone substantial changes over the past few decades, but lacks extensive assessment. A multispectral remotely sensed dataset was used to assess changes in land use and land cover of the Sanctuary over almost 27 years (1993–2021). A maximum likelihood algorithm was used to classify Landsat images for the years 1993, 2006, and 2021 and geometric correction were rectified in Earth Resources Data Analysis System (2014) software. The results of the present study indicate that the study area has undergone major changes between 1993 and 2020. Forest and snow-covered areas have shrunk, while non-forested areas like grassland, barren, scrub, built-up areas, and river beds have shown positive growth in the sanctuary. Within the studied time period, a total loss of 5.9 km2 was recorded for the forest areas and 1.5 km2 for the snow covered areas. The main threats driving the Land use and Land cover change in the Sanctuary were grazing pressure, natural resource exploitation, poaching, and development projects. The results of this study may potentially provide information to planners, and decision-makers for the sustainable management of natural resources and implementing important management decisions in order to preserve the rich biodiversity of the Sanctuary.
