Summary

Analysts estimate that nearly 2 million of Uganda's 31 million people experience food insecurity due to supply problems or rising prices. Nearly 80% of the people in some regions depend on food aid to survive. Such problems could worsen as Uganda's population, which has been increasing at more than 3% per year, surges to an estimated 100 million by 2050. To keep pace, Uganda's farmers will need to at least triple current harvests. Scientists can play an important role in boosting yields by helping farmers get the most from fundamental resources, such as water (see p. 800), soil (see p. 801), and seeds (see p. 802). But complex social, economic, and psychological challenges are raised by food insecurity; science alone won't transform fields from brown to green.
