From a total of 391,000 known plant species, 5,538 are known to have been used for human food since the origin of agriculture. Out of these, just three—rice, wheat, and maize—provide more than 50% of the world’s plant-derived calories.

The reduction of agricultural biodiversity in global food systems is of increasing concern—leading to a lack of available foods to constitute diversified diets, particularly in the developing world.

Bioversity International leverages the potential of diverse crop species and varieties in order to strengthen food security, increase access to nutritionally-adequate diets, build resilience to crop production, and help communities to diversify local food production.

We work with farmers to increase their food security, both directly and indirectly, and improve their access to markets. By increasing the markets for diverse species, farmers perceive the incentives to cultivate them and expand their livelihoods. Along with this indirect strengthening of food security, communities also benefit directly from consumption of diverse and nutritious species and varieties.

Where we work

Our work in marketing diversity is focused in Bolivia, Benin, Guatemala, Peru, Mali, India, Kenya, Botswana, Cameroon, Senegal and Zimbabwe, with research approaches that can be adapted to other regions. 

Millets in India

Bioversity International has been working with partners for 15 years to promote millet use and conservation. The inclusion of millet as one of the grains subsidized by the government in India’s National Food Security Act—which guarantees a quantity of grain per person at low prices—has also served to highlight the grain. Bioversity International’s efforts have contributed to improved markets for millet-based dishes, and a switch from white rice to minor millets has resulted in the haemoglobin levels of school children to increase up to 37% within 3 months.

What's next?

We are working in Mali, India and Guatemala to build the capacity of farmers, researchers and government actors to integrate nutrition, resilience and income considerations in the development of more sustainable farm and livelihood systems.

CGIAR partnership


This research area contributes to CGIAR Research Program on Policies, Institutions and Markets – our role is to address key research questions relating to the role of agricultural biodiversity in value chains and how market strategies based on the conservation and use of agricultural biodiversity can help improve income for people living in rural poverty. It also contributes to the CGIAR Research Program on Climate Change, Agriculture and Food Security
