Abstract Background In diverse agroecological settings, determining the magnitude and intensity of drought conditions is crucial for enhancing food security climate resilience. However, in regions with bimodal agroecology, specific growing season characterized by frequent severe droughts remains uncertain. This study aimed to assess spatiotemporal dynamics Welmel watershed southeastern Ethiopia from 2000 2022 using standard precipitation index (SPI) vegetation condition (VCI). The investigation utilized data Moderate Resolution Imaging Spectroradiometer Climate Hazards Group Infrared Precipitation Stations, accessed through Google Earth Engine cloud computing platform. Results analysis SPI VCI demonstrated that experienced mild extreme throughout period. Between two seasons, March–May (MAM) September–November (SON), MAM was found be more susceptible than SON both indices. SPI-12 annual assessments identified 2011, 2019 as years events. spatial distribution severity pronounced lowland highland regions. Sen’s slope revealed varied trends, annual, values decreasing 1.47, 0.28 0.14, respectively. A strong significant correlation observed between seasonal SPI-3 ( r = 0.68), while weak not statistically 0.36). Conclusions research provides insights rain-fed agricultural sectors policymakers, highlighting importance minimizing potential drought-related catastrophes cultivation crops. future, an in-depth examination extent rainy seasons may prove paramount sector policymakers.
