ITHACA, N.Y. — Cornell University will receive a $10.5 million investment from the United Kingdom to help an international consortium of plant breeders, pathologists and surveillance experts overcome diseases hindering global food security efforts.
The funds will be used for “Delivering Genetic Gain in Wheat (DGGW),” a four-year project that enlists national partners in Kenya and Ethiopia as well as scientists at international agricultural research centers that focus on wheat, including the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA). Advanced research laboratories in the United States, Canada, India, Turkey, Denmark and South Africa collaborate on the project.
The U.K. aid investment will build on a $24 million grant Cornell received from the Bill and Melinda Gates Foundation in March 2016.

“Wheat provides 20% of the calories and protein consumed by people globally, but borders in Africa, South Asia and the Middle East are porous when it comes to disease pathogens and environmental stressors like heat and drought that threaten the world’s wheat supply,” said Ronnie Coffman, international plant breeder and director of international programs at Cornell University, who leads the global consortium. “We are using the modern tools of comparative genomics and big data to develop new varieties of wheat for smallholder farmers that incorporate resilience to abiotic stresses and diseases such as rust and septoria.”
Cornell said the U.K. aid investment builds on the successes of the Borlaug Global Rust Initiative (BGRI) and the Durable Rust Resistance in Wheat (DRRW) project, which were funded jointly by the British people and the Gates Foundation from 2008 to 2016.
“Over the last nine years, we have built a global community of wheat scientists whose efforts have so far prevented the global epidemics of Ug99 stem rust anticipated by Dr. Norman Borlaug back in 2005,” Mr. Coffman said. “Working with national and international partners, we have delivered more than 65 varieties of wheat with improved resistance to rust and increased wheat yields globally.”
Mr. Coffman said wheat provides most of the food for the poorest people in Africa and southern Asia, and it is those people who have benefitted the most from the DRRW and the BGRI’s successes developing new strains of wheat that are high yielding, rust resistant and nutritious.
“Smallholder farmers will benefit further under the DGGW,” he added.
The global consortium involved in the project includes more than 2,500 scientists from 35 international institutions spread across 23 countries. Agricultural scientists from 37 countries contribute data to a surveillance network coordinated by Dave Hodson, senior scientist with the International Maize and Wheat Improvement Center (CIMMYT), based in Ethiopia, who directs the rusttracker.org global wheat rust monitoring system.
“Deadly wheat pathogens have been moving from the wheat fields of East Africa into the Middle East,” Mr. Hodson said. “Thirteen countries are now infected with 13 variants of the highly virulent Ug99 stem rust. Other dangerous stem and yellow rust race groups are also emerging. We need effective and responsive surveillance and early warning systems in place because it’s not just Ug99 that we have to worry about. New threats are coming up. We’re seeing a dramatic expansion in geographical range and new variants emerging within key race groups. Ug99 was a wakeup call, and we’ve benefitted from the investments that have been made in rust surveillance. But there’s no room for complacency because new threats are emerging. We need to be flexible and address any new concerns that arise.”
The four-year grant also will allow the DGGW to focus on capacity building and training the next generation of hunger fighters.
“Collaborative agreements with national governments and agencies are in place to improve the in-country capacity to screen thousands of wheat samples from every continent to identify disease- and heat-resistant lines,” said Maricelis Acevedo, wheat rust pathologist and senior research associate at Cornell and the associate director for science for the DGGW project. “And resources are being invested to strengthen the pipeline to train young scientists in at-risk countries, both men and women.”
According to the Food and Agriculture Organization, world demand for wheat is expected to increase up to 60% by 2050, as the global population reaches or exceeds 9 billion people.“Globally, we need to produce more wheat with limited natural resources and in more sustainable ways,” Ms. Acevedo said. “Breeding, surveillance, capacity building, training and advocacy are critical.”
