Sweet potato boosts health and incomes. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Associated with Projects R6508 (in part), R7498 and R8282. Simple techniques for improved sweet potato transport, curing, packaging and storage can help farmers, market traders and consumers to cut their post-harvest losses. This crop's hardiness and, more recently, its promise for combating vitamin A deficiency have rightfully gained it a reputation as a lifesaver. Yet problems after the harvest limit its contribution to incomes, food security and health. These technologies, which have enormous potential for saving lives and improving livelihoods, have been tested in Tanzania with good results and are now ready for wide dissemination. Consumers also have shown their approval of new vitamin A-rich orange fleshed varieties, which are being promoted in Kenya, Tanzania, Uganda, Mozambique, Ghana, Nigeria, Rwanda, Ethiopia and Zambia.
