This report summarises a systematic review by Oya and colleaguesthat assesses the impact of agriculture certification schemes on improving socio-economic conditions for workers and farmers in low- and middle-income countries. The authors found that the impact of certification schemes on yields is mixed. Prices for some certified products increased and farmer income from the sale of the certified product was slightly higher. However, the average household incomes and asset ownership of farmers did not increase. They also found that the average workers’ wages were no different or slightly lower. There was a significant impact on school attendance in Africa, but not in Asia and Latin American and the Caribbean.
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.
