Impact of improved rice varieties on household food security in Northern Ghana: A doubly robust analysis

Abstract

AbstractThis study determines the impact of the adoption of improved rice varieties on household food security using farm‐level data from 900 households in Northern Ghana. We employed the doubly robust inverse probability weighted regression adjustment procedure complementary with a propensity score matching approach on two indicators of food security (household dietary diversity score and subjective food security). Across all the various estimation procedures, we observed consistent positive effects of the adoption of improved rice varieties on household food security. Policies that enhance diffusion and adoption of improved rice varieties should be encouraged to improve food security among farm households.
