Abstract

This study presents a model to estimate potential benefits of drought-tolerant varieties of maize, sorghum and millet in Kenya, Uganda and the Amhara region of Ethiopia. In addition to the benefits from mean yield increases, the model takes into account risk benefits associated with yield-stabilising varieties. Ex ante estimates provided for different drought zones and for different household types within drought zones of each country suggest that drought resistance generates substantial benefits from both mean yield improvements and yield variance reductions for both consumers and small, medium and large producers.
