The effects of food systems interventions on food security and nutrition outcomes in low- and middle-income countries - 3ie Evidence gap map report 16, 2021

3ie evidence gap maps are thematic collections of information about impact evaluations and systematic reviews that measure the effects of international development policies and programmes. This present evidence gap map relates to the effects of food systems interventions on food security and nutrition outcomes. A total of 1,838 impact evaluations and 178 systematic reviews were identified.

The research questions were the following:

  • What are the extent and characteristics of existing empirical evidence regarding the effects of selected food systems interventions on food security and nutrition outcomes in L&MICs?
  • What are the major primary and synthesis evidence gaps in the literature that could be prioritised for primary research and/or evidence synthesis?

Based on the results presented in this review, two recommendations are made to policymakers:

  • Make use of high-quality systematic reviews when designing and developing new policies and programmes: A total of 34 high-quality systematic reviews were identified
  • Consider investing in under-researched areas: The map identified several intervention-outcome combinations where there is relatively little impact evaluation evidence
