Biodiversity in the Caspian Basin: Ecogeographical Challenges, Ecological Restoration and Pathways toward Sustainable Development

Abstract

The Caspian Basin represents one of the most ecologically complex and geographically diverse regions of Eurasia, characterized by unique ecosystems, rich biological resources, and significant environmental gradients. However, increasing anthropogenic pressure, rapid urbanization, industrial pollution, unsustainable land use, climate change, and hydrological alterations have intensified ecological degradation across the region. These processes have led to habitat fragmentation, biodiversity loss, soil and water contamination, and declines in endemic and economically important species. This study evaluates the major ecogeographical risks affecting biodiversity within the Caspian Basin and explores ecological restoration approaches to support sustainable regional development. The research integrates ecological observations, geospatial analysis, biodiversity assessment, and environmental monitoring data collected from different ecosystems surrounding the Caspian region. The findings show that ecosystem restoration, landscape-level conservation planning, and sustainable environmental management strategies are essential to improving ecological resilience. The study also highlights the importance of interdisciplinary scientific cooperation, modern remote sensing technologies, and ecosystem-based management approaches to preserve biodiversity and maintain ecological stability within the Caspian Basin. The obtained results provide a scientific framework for future conservation planning and sustainable development initiatives in ecologically vulnerable regions
