Determinants of Crop Diversification and Its Effects on Household Food Security in Northern Ghana

This study analyses factors that determine smallholder farmers’ crop diversification decisions and their effects on household food security in Northern Ghana. A total of 1,284 households were sampled across the five northern regions of Ghana. Herfindahl Index for measuring crop diversification was used. The study found average crop diversity to be 0.55 and about 61 per cent of the sampled farmers had values above the average which indicated high crop diversification in the study area. The study also estimated the determinants of crop diversification and their effects on household dietary food security using the conditional mixed process model. Upon examining the determinants of crop diversification, occupation, technology adoption, labour, extension contact and farm size were identified as significant determinants. The study also computed the Household Food Consumption Score as a proxy for measuring food security. The result indicated that crop diversification contributes significantly to improving household food security status in Northern Ghana.
