摘要

Land use and land cover change strongly influences hydrological processes and watershed functioning in rapidly transforming landscapes. This study modeled future land use and land cover change and its hydrological implications in the Dabus watershed of southwest Ethiopia for the period 2019–2029. Historical land use and land cover data from 2019 were used to simulate the 2029 scenario using an empirical and dynamic land use modeling framework implemented in the TerrSet Geospatial Monitoring and Modeling System. The projected land use and land cover distribution for 2029 indicates expansion of shrubland to 510.9 km² (25.9%), water bodies to 149.3 km² (7.6%), and built up areas to 980.5 km² (49%), while forest land declines to 31.1 km² (1.6%), cultivated land to 199.2 km² (10.1%), barren land to 85.4 km² (4.3%), and grassland to 18.6 km² (0.9%). Relative to 2019, shrubland, water bodies, and built-up areas increase by 35.7 km², 13.1 km², and 0.9 km², respectively, whereas forest land, cultivated land, barren land, and grassland decrease by 5.5 km², 31.3 km², 11.6 km², and 1.3 km². These changes, except for barren land, are likely to accelerate surface runoff and increase flood susceptibility in the watershed. The expansion of built-up areas and the continued loss of forest and cultivated land highlight the need for immediate land and water resource management interventions. The integrated empirical and dynamic modeling approach provides a valuable decision support framework for sustainable watershed management in southwest Ethiopia.
