The study estimated the average annual soil loss for sustainable crop production in the Upper East of Ghana, using the Revised Universal Soil Loss Equation, sensitivity, correlation and regression analyses to understand the factors driving erosion in the area. Rainfall data from Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) was used to determine the rainfall erosivity, soil erodibility from the Harmonized World Soil Database, the Slope Length and Steepness from the Shuttle Radar Topographic Mission data, the Cover Management and Control Practices from Landsat satellite data from the years 2000, 2010 and 2020. The northeastern region was identified as the most susceptible to soil loss. The region recorded an annual average soil loss of 50.26 tons/ha/yr, 56.50 tons/ha/yr and 39.61 tons/ha/yr in 1990–2000, 2001–2010 and 2013–2020, respectively. A sensitivity analysis showed that C and R factors profoundly impact soil loss in the region. The regression analysis (R-squared = 0.686, n = 1374) revealed that the significant factors influencing soil erosion are slope (p |
