This paper adds to the sparse literature on irrigation-diet linkages by contributing fresh evidence from Afghanistan and addresses the lacuna regarding the pathways through which such linkages may operate. Using data from the latest round of the nationally representative Afghanistan Living Condition Survey (2013-14), this study explores the role of irrigation in dietary diversity in Afghanistan. Results show that possession of irrigated land and garden plots are positively associated with household dietary diversity. Two pathways underlie this relationship. On the one hand, irrigation facilities are positively correlated with diversity of food intake from own production.
