This EGM assesses the availability of rigorous evidence on the impact of interventions in the agricultural sector in L&MICs. The results suggest that there are large quantities of evidence on the impact of interventions designed to disseminate technologies and knowledge to farmers, increase access to financial and insurance services, and establish formal land rights. However, there is limited availability of evidence on interventions designed to strengthen agricultural markets, particularly those interventions targeting non-producer actors in these markets. There is a need for impact evaluation research to remedy these gaps. The reliability of evidence from systematic reviews in this sector is limited, and the field may benefit from up-to-date, high-quality syntheses of evidence on such topics as land rights reform and access to financial and insurance services.
