Owing to persistent challenges of food and nutritional insecurity, recent literature has focused on the role diversity of farm production has on food consumption diversity, particularly for smallholder households. Yet, the relationship between farm production diversity and household food consumption diversity remains complex and empirical evidence is, so far, mixed. The present article assesses this relationship using two districts-Kilosa and Chamwino-with contrasting agro-ecological and market contexts in rural Tanzania. These districts represent the majority of farming systems found in Tanzania as well as in several countries within the region. We used household data and employed descriptive as well as multivariate regression analyses. The results indicated a positive role of farm production diversity for food consumption diversity in the district with relatively harsh climatic and agro-ecological characteristics and poor access to markets. Furthermore, increased farm production diversity was generally associated with seasonal food consumption diversity. However, results suggested a lesser role of farm production diversity in the presence of better agro-ecological and market access characteristics. These findings imply that promoting farm production diversity should consider the existing agro-ecological and market characteristics. In addition, achieving increased food consumption diversity among rural households may require effective market related infrastructure and institutions.
