摘要

The landscape is a direct manifestation of the ecosystems in a region, and its changes can act directly or indirectly on a region’s ecological, economic, and environmental systems. Therefore, understanding dynamic landscape changes and risk assessment is essential for conserving and managing landscapes and the sustainability of their biotic and abiotic components. This study illustrates the use of geospatial technology for landscape characterization, change analysis, and ecological risk assessment. The Chambal landscape in India hosts various endemic and globally threatened species within its riverine, ravine, and forest ecosystems, making it the focus of this study. The study employed geospatial technologies to understand land use and land cover status and its changes at three base years: 2009-10, 2015-16, and 2021-22. The goal was to assess the impact of previous management practices and understand the current status to determine appropriate management interventions to be carried out in the landscape. In addition, the study examined various factors negatively affecting the landscape, including land degradation, fire, forest degradation, flood susceptibility, moisture stress, sand mining, waterlogging, and the conversion of ravine lands into agricultural areas. These factors were evaluated along with climatic data to address ongoing challenges and propose actions for improvement. The study documented the present and past conditions of the landscape features and its impacts and hotspots of positive and negative changes, analyzed the drivers of these changes, and assessed the threats the ecosystem faces for landscape planning to minimize adverse environmental impacts and enhance positive effects to the ecosystem.
