This review examines the effectiveness of these preventive interventions in achieving their aims, as well as identifying factors behind successful implementation in low and middle-income countries.

  • PLS Title Training, innovation and technology interventions can improve livelihoods for smallholder farmers in Africa, but there are few rigorous studies
  • PLS Description 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.
