Integrated Farming Systems (IFS) have been implemented in Benin to enhance agricultural productivity among resource-poor farmers. The analysis employs a random-effects meta-regression model with robust standard errors to aggregate study findings across various IFS interventions in Benin. A thematic review identified consistent themes of improved crop yields (by an average of 30%) and enhanced soil health, although variability exists between specific farming practices. IFS have demonstrated significant potential for improving resource-poor farmers' economic outcomes and environmental conditions in Benin. Further localized and diversified IFS initiatives are recommended to address regional-specific challenges and maximise benefits for diverse farmer groups.
