Background: Climate change and associated prolonged meteorological drought have affected crop productivity and food security for decades across the world. Most developing counties including Uganda are majorly affected due to their limited social, economic and technical capacity in climate change mitigation. Isingiro district for instance, is located in the Ugandan dry cattle corridor and has been affected by prolonged meteorological drought resulting in limited crop productivity and food insecurity for the last four decades. The extent to which meteorological drought has affected Isingiro district is not well documented hence the need for this study. The study aimed at mapping meteorological drought-vulnerable extent for the selected six sub-counties of Isingiro District, South Western Uganda. Methods: Precipitation datasets from 1982-2022 were downloaded from NASA powers website. SPI calculator, QGIS 3.4 and ArcGIS10 software were used to calculate SPI values and map the extent of meteorological drought in the selected sub counties. Result: Results show increasing average annual negative and extreme meteorological vulnerability following the order: Masha -2.57 greater than Mbaare -2.40 greater than Kikagate -2.28 greater than Isingiro Town Council -2.26 = Rushasha -2.26 greater than Kashumba -2.05 indicating extremely high vulnerability of the study sub counties to meteorological drought. Results are discussed, conclusions and recommendations are provided in the manuscript.
