Current status

Sweet potato is climate-resilient and orange-flesh (OFSP) is vitamin-A rich. Production concentrated in lake basin. CIP-led OFSP varieties scaling for nutrition + drought tolerance.

Future trends

Orange-fleshed sweet potato (OFSP) varieties expanding for child-nutrition programmes. Climate-resilience makes it attractive substitute as maize stresses. Limited urban demand growth.

Needs & gaps

Limited mechanization, fragmented marketing, weak processing. Cold chain absent.
