ABSTRACT: Climate variability has become a major constraint to agricultural productivity in Sudan, particularly in rain-fed regions such as Gedaref State. This study analyzes the impacts of temperature and rainfall variability on sorghum yield using long-term climate data (1961-2014) and sorghum production records (1970-2007). Mann-Kendall trend tests, correlation, and multiple regression analyses were applied to assess climate-yield relationships. The FAO AquaCrop model was used to project future yield changes under changing climate conditions. Results revealed significant increases in maximum and minimum temperatures (p
