Undernutrition and low dietary diversity remain big problems in many developing countries. A large proportionof the people affected are smallholder farmers. Hence, it is often assumed that further diversifying small-farmproduction would be a good strategy to improve nutrition, but the evidence is mixed. We systematically reviewstudies that have analyzed associations between production diversity, dietary diversity, and nutrition insmallholder households and provide a meta-analysis of estimated effects.

Enhancing the diversity of agricultural production systems is increasingly recognized as a potential

means to sustainably provide diversified food for rural communities in developing countries, hence

ensuring their nutritional security. However, empirical evidences connecting farm production

diversity and farm-households’ dietary diversity are scarce. Using comprehensive datasets of

market-oriented smallholder farm households from Indonesia and Kenya, and subsistence farmers
