While summer rains have increased during the past 20 years, temperatures have increased as well, amplifying the effects of droughts. Crop yields are low but the population is growing, pointing to rising food insecurity.
Modest declines in rainfall, accompanied by increases in air temperatures, declining farmland per person, along with trends in population and agriculture could lead to a 30% reduction in per capita cereal production by 2025.
The data shown here depict drying trends in one of the world's most food insecure regions. Decreasing rainfall since 1980 accompanied increases in air temperature greater than global warming.
Long-term reduction in rainfall and increasing temperature threaten Uganda's future food production prospects; combined with rapid population growth these factors could increase the number of people who are at risk during the next 20 years.
