摘要：Many poor people living in Africa depend on their small farms for survival. There has been a lot of interest in trying to reduce poverty in the region by supporting these farmers to produce more and make a profit from their farms. Such interventions include training farmers and introducing them to new farming techniques and products, such as new crop types or fertilisers. Although a substantial amount of money has been invested in these approaches by governments and international donors, the effects of these interventions on food security and economic outcomes are unclear. This review examines the effectiveness of training, innovation and new technology interventions on the economic outcomes and food security of smallholder farmers in Africa. Interest has grown in interventions to support smallholder farmers because such interventions have the potential to improve both household income and food security. This review confirms providing smallholders with new biological or chemical inputs, particularly orange‐fleshed sweet potato, can lead to improved income and nutrition status. More high‐quality studies are needed to assess other types of training, innovation, and new technology interventions. Research is also needed to assess whether such interventions have sustainable, long‐term effects and whether they may cause harm to farmers or their communities.
