We found a consistent result across models, indicating that adoption increased food security, and that the impact of adoption varied with the level of adoption. On average, an increase of one acre in the area allocated to improved maize varieties reduced the probabilities of chronic and transitory food insecurity from between 0.7 and 1.2 % and between 1.1 and 1.7 %, respectively. Policies that increase maize productivity and ease farmers? adoption constraints can ensure the allocation of more land to improved technologies and, in doing so, enhance the food security of households.Collection: CIMMYT Staff Publications Collection
