Young children remain the most vulnerable population to food insecurity--low birthweight and stunting continue to be among the most visible effects of malnutrition. Helen Keller International (HKI) implemented an Enhanced Homestead Food Production program to increase access to and availability of diverse diets. This paper reviews the evolution and impact of HKI’s Enhanced Homestead Food Production (EHFP) programme and identifies core components of the model that address the underlying determinants of stunting.
