The International Initiative for Impact Evaluation (3ie) is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding, producing and synthesising high-quality evidence of what works, how, why and at what cost. We believe that better and policy-relevant evidence will make development more effective and improve people's lives. 3ie systematic reviews 3ie systematic reviews examine available high-quality evidence on the effects of social and economic development interventions in low-and middle-income countries. These reviews follow scientifically recognised review methods, and are peer reviewed and quality assured according to internationally accepted standards. 3ie is providing leadership in demonstrating rigorous review methodologies, such as using theory-based designs, for combining different types of evidence suited to respond to the complex and dynamic contexts and challenges of development. 3ie also publishes summary reports based on the full reviews that are designed for use by policymakers and programme managers.

SummaryThe majority of the rural poor in Africa engage in smallholder farming as a livelihood strategy. At the same time, supporting the practice of smallholder agriculture holds the potential to improve farming households' level of food security as well as local economies in rural areas. Agricultural productivity in Africa stands at one-third to half of global productivity and, although the Green Revolution has rapidly improved social and economic livelihoods in other former developing regions, it is by and large absent from the continent.Programmes that support African smallholder agriculture by implementing training programmes and introducing new technologies and agricultural innovations aim to help release the untapped potential of the African agricultural sector. But we know little about which programmes and approaches are most effective at improving smallholders' food security and economic outcomes. This is the first systematic review of the available research evidence to address this issue. Our objectives were to systematically review the evidence on the effects that training, innovation and new technology have had on African smallholder farmers' economic outcomes and food security.
