DFID funds the development of new crop varieties which are high yielding, climate and disease resilient, and have improved nutritional value. This includes flood tolerant rice that reduces risks for 10 million smallholders in South Asia, and drought tolerant maize that delivers more stable yields under climate stress being grown by 3 million households in Africa. DFID also supports the development and delivery of biofortified crops, which are conventionally bred with higher levels of zinc, iron and Vitamin A, as well as climate-resilient traits such as drought and pest tolerance. By 2018, DFID had reached over 8 million households with these climate-resilient and nutritious crops such as high iron beans and pearl millet, and orange sweet potato (high in Vitamin A).

DFID plans to reach 13.5 million households in countries with high levels of nutrition insecurity by 2022 with these new biofortified crops. DFID tracks outcomes closely through its international research partners, and invests in the generation of high quality evidence to measure impact and cost-effectiveness of such interventions.
