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.
This report summarises a systematic review that examines which promotional approaches are effective in changing handwashing and sanitation behaviour and which implementation factors affect the success or failure of such interventions.
Safe water, sanitation and hygiene (WASH) behaviours, such as treating drinking water, washing hands at key times or using a latrine rather than defecating in open spaces, are cornerstones of building strong, healthy communities and reducing mortality due to diarrhoea and other preventable diseases. 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.
This systematic review summary by Benjamin-Chung and colleagues tries to identify mechanisms that trigger spillover through geographic or social proximity, learning or imitation, norm-shaping, income and substitute effects, general equilibrium effects and relative deprivation.
This report by Lemmi and colleagues is based on a systematic review that looked at the impact of community-based rehabilitation (CBR) on health, education, livelihoods, social inclusion and empowerment.
