What Works in Agriculture?

Key findings from our new Policy Brief, ‘Programs Promoting Sustainable Agriculture for Smallholders’:

a. Formal land titling has positive effects on agricultural productivity and incomes of freehold land titles in Asia and Latin America, but not in Africa

b. Technological innovations such as improved crop varieties are particularly effective in boosting production and have a positive impact on household food security. However, there is no evidence that training on its own is effective in promoting sustainable agriculture.

c. Farmer Field Schools can help to improve farmer knowledge, the adoption of improved practices, farm yields, and incomes for farmers who participate in small-scale pilot programs. However, neighbouring farmers do not benefit from a diffusion of knowledge.

d.  Payment for Environmental Service schemes have only modest effects and may not be cost-effective

In our new Policy Brief, Hugh Waddington summarizes evidence from five systematic reviews covering the following interventions: land titling, training and technology, farmer field schools, payment for environmental services, and decentralized forest management.

This new series is designed to inform social policy and practice decisions by summarizing evidence from a range of Campbell systematic reviews in specific subject areas.

Each Policy Brief describes what has been learned in key topic areas, what questions remain, and presents ideas for future research and policy work.
