Resumen
Descripción
Supply chains for nutritious (“protective”) foods in Africa south of the Sahara are often poorly developed, especially for perishable crops that are vulnerable to wastage. We used LSMS-ISA surveys and geographic information system (GIS) data to explore which factors predict production patterns of four protective food crops (pulses, nuts and seeds, vegetables, and fruits) relative to cereals and starchy roots and tubers (grouped under staples) in Ethiopia, Malawi, Tanzania, and Uganda, with a focus on potential inter-ventions to improve production, trade, and consumption of these foods. Plot-level irrigation adoption is the strongest predictor of fruit and vegetable production, along with precipitation, suggesting that water availability is a major precondition for pro-ducing these protective foods. In contrast, pulses and nuts and seeds can be grown in drier and warmer conditions. Better market access is also associated with higher production of fruits and vegetables, but the association is weaker than that of water access. Investing in and expanding irrigation-especially small-scale irrigation-has strong poten-tial to yield high returns in East Africa, especially for poor households that cannot afford to invest in capital-intensive irrigation technologies. Irrigation investments may need to be complemented by investments in roads, rural elec-trification, and cold storage chains to promote efficiency of postharvest supply chains and reduce marketing costs.
