This four-year mixed-methods study examined the effect that agroecological farming practices can have on food security and dietary diversity in Malawi. Intercrops and crop diversification increased household food security. Use of organic soil amendments, which lessen the chance of metal accumulation by plants, resulted in increased dietary diversity. The researchers also found that when spouses discuss farming, they are 2.4 times more likely to have both food security and dietary diversity. Participatory agroecology research approaches that promote farmer experimentation and community-based education on gender equity can improve food security and nutrition.
