Land use land cover is dynamically changing in Ethiopia, with far-reaching implications onrnrecurrent droughts and land suitability status. The central highlands in particular are recognizedrnfor a unique precipitation pattern, intensive cultivation, periodic droughts, and land degradation.rnThe study intends to use satellites (mainly Landsat) to map land-use dynamics, droughtrnsusceptibility, and agricultural suitability and comparative analysis in Basona Werana districtrn(Woreda). The land use land cover seemed to be dominated by cultivated land with approximatelyrn74.34 percent (3/4th) of the area in 2021. Non-dominant LULC types share the rest 25.66% in thernfollowing percentage. Shrub and Bush (15.37%), Forests (5.2%), Built-up and settlement (2.87%),rnWetlands (1.22%), and water bodies, pasture land, and bare land collectively account for 1% ofrnthe area. While cultivated land, grassland, shrubland, built-up and settlement areas, and waterrnbodies have had rising land cover change trends over the last 32 years, forests, bare land, andrnwetlands have witnessed a decreasing trend. The Vegetation Condition Index (VCI) andrnNormalized Difference Drought Index (NDDI), among other indices, were used to estimaternhistorical and non-temporal droughts respectively. While VCI estimated that extreme droughtrnconditions affected 30.18%, 7.34%, 22.55%, and 1.77% of the area in 1989, 2000, 2010, and 2021rnrespectively, NDDI estimated it to be 35.91%, 40.58, 39.23, and 53.87% in those same years. Tornsee the real context of cropland suitability constraints such as elevation, slope, soil type, SoilrnAdjusted Vegetation Index (SAVI), Normalized Difference Water Index (NDWI), and riverrnproximity were weighted by various degrees of influence. The result demonstrates 5.35% of thernarea is highly suitable, 49.9% is moderately suitable, 28.72% is marginally suitable, 13.46% is lessrnsuitable and 2.56% is not suitable for agriculture. In this particular study, UAV imagery wasrnparticularly useful for ground-truthing satellite-based classification. It does, however, haverninherent limitations when it comes to addressing standardized drought indices and land suitabilityrnevaluations. Choosing the path of sustainable development would provide a long-term solution tornBasona Werana's drought susceptibility. In agrarian areas like Ethiopia, LULC and droughtrnconditions must be closely monitored.
