This report is based on a systematic review by Stewart and colleagues that synthesises evidence on the effects of training, innovations and new technology on African smallholder farmers’ income, assets and food security. There is tentative evidence that agricultural input innovations may increase the nutritional status of farming households and, to a lesser degree, the monetary value of farmers’ harvests. There is also evidence that bottom-up training interventions may be able to improve farmers’ income levels.

Many studies have shown the health benefits of WASH, and factors that affect initial adoption of short-term WASH use. Few have assessed the determinants of long-term, sustained WASH practice.
