Environmental health and biodiversity

The world needs better management of water, soil, nutrients, and biodiversity in crop, livestock, and fisheries systems, coupled with higher-order landscape considerations as well as circular economy and agroecological approaches.

CIMMYT and CGIAR use modern digital tools to bring together state-of-the-art Earth system observation and big data analysis to inform co-design of global solutions and national policies.

Our maize and wheat genebanks preserve the legacy of biodiversity, while breeders and researchers look at ways to reduce the environmental footprint of agriculture.

Ultimately, our work helps stay within planetary boundaries and limit water use, nutrient use, pollution, undesirable land use change, and biodiversity loss.

Researchers use genome-wide association mapping approach to identify new regions with resistance to the disease.


Global networks present unified and transdisciplinary strategy to protect key crops from devastating pests and diseases.

As climate breakdown and worldwide conflict continue to place the food system at risk, seed banks from the Arctic to Lebanon try to safeguard biodiversity.


Ram Kanwar Malik named Honorary Member by the Weed Science Society of America for research on herbicide-resistant weed Phalaris minor affecting wheat crops.


Over millennia, natural selection and humans have systematically adapted the plant species that provide food and other vital products, changing their physical and genetic makeup for enhanced productivity, nutrition and resilience. Plant breeders apply science to continue improving crop varieties, making them more productive and better adapted to climate extremes, insects, drought and diseases.


Researchers evaluate the use of genomic selection in wheat breeding against deadly fungal disease.

A new article in the New Yorker praises the cutting-edge technology CIMMYT, CGIAR and other scientists are developing to produce a second Green Revolution that doesn’t repeat the mistakes of the first, putting the experiences and challenges of farmers at the heart of it.


Researchers hypothesized that many wild wheat accessions in genebanks feature useful traits that can help diversify breeding programs.
