Wheat Disease Early Warning Advisory System (DEWAS)

The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the world’s largest and most advanced crop pathogen surveillance systems. With Wheat DEWAS, researchers are building an open and scalable system capable of preventing disease outbreaks from novel pathogen strains that threaten wheat productivity in food vulnerable areas of East Africa and South Asia.

The system builds from capabilities developed previously by multi-institutional research teams funded through long-term investments in rust pathogen surveillance, modelling, and diagnostics. Once fully operationalized, the project aims to provide near-real-time, model-based risk forecasts for governments. The result: accurate, timely and actionable advice for farmers to respond proactively to migrating wheat diseases.

The Challenge

Farmers growing wheat face pathogen pressures from a range of sources. Two of the most damaging are the fungal diseases known as rust and blast. Rust is a chronic issue for farmers in all parts of the world. A study in 2015 estimated that the three rust diseases — stem, stripe and leaf — destroyed more than 15 million tons of wheat at a cost of nearly $3 billion worldwide. Wheat blast is an increasing threat to wheat production and has been detected in both Bangladesh and Zambia. Each of these diseases can destroy entire harvests without warning, wiping out critical income and food security for resource-poor farmers in vulnerable areas.

The Response

Weather forecasts and early-warning alerts are modern technologies that people rely on for actionable information in the case of severe weather. Now imagine a system that lets farmers know in advance when dangerous conditions will threaten their crop in the field. Wheat DEWAS aims to do just that through a scalable, integrated, and sustainable global surveillance and monitoring system for wheat.

Wheat DEWAS brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Together, the researchers are focused on six interlinked work packages:

One year of Women in Crop Science at CIMMYT

To mark International Women’s Day 2023, Nele Verhulst, cropping systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT), shares progress from the Women in Crop Science group and how their work tries to contribute to gender equality in agriculture and science.

Growing up in the nineties in Belgium, I was interested in feminism, but I also assumed that the fight for equal rights for women and men had been fought and won. Studying bioscience engineering in the 2000s, more than half of the students were women, so this demonstrated to me that we were all set (although the large majority of professors were men, it seemed to be just a matter of time for that to be resolved). I have now been working in Latin America as an agronomist and researcher for more than 15 years and have come to realize that there is still a lot of work to do to achieve equal opportunities for female farmers, farm advisors, scientists, and other professionals in agriculture.

At CIMMYT, between 20 and 25 percent of staff in the science career track – careers involving field, lab, data, and socioeconomic work – are female. Because of that, Alison Bentley and I started a group of women in crop science at CIMMYT about one year ago on the International Day of Women and Girls in Science in 2022. In our first meeting, we aimed to connect, discussed how to build a network (we did not even have a list of all women in science at CIMMYT, so it was hard to know who to invite), and decided whether we wanted to commit to additional actions to achieve a more inclusive environment at CIMMYT.

Since that first meeting, we have organized coffee mornings and other events, and have split into smaller working groups to draft action plans on ten topics: gender in the workplace strategy development, advancement for locally recruited staff, mentorship, recruitment processes, microaggressions, harassment policies, work-life balance, family friendly work environment, raising external awareness about women in agriculture, and ensuring internal visibility.

Our group is also linked to the worldwide network of Women in Crop Science and the One CGIAR Women in Research and Science (WIRES) group.

I have enjoyed being able to make some first small changes – who knew sanitary facilities would turn out to be a recurring topic! – but most of all I have loved the opportunities over the past year to connect with women with a shared passion for crop science in all its aspects. That passion and the opportunities it creates to improve the lives of farmers and rural communities is the most important thing we are celebrating today.

Ethiopia’s Experience of Wheat Production Exemplary to African Countries: CIMMYT

Rabe Yahaya, agricultural mechanization expert at the International Maize and Wheat Improvement Center (CIMMYT), spoke to the Ethiopian News Agency (ENA) about the country’s wheat production.

Ethiopia is the second largest wheat grower in Africa and has high levels of demand for the crop. Shortages of grains, cereals and agricultural inputs such as fertilizer caused by the Russia-Ukraine conflict are leading the Ethiopian government to focus heavily on increasing the country’s productivity to rely less on imports.

Prime Minister Abiy Ahmed recently launched national exports of wheat/ “We have made Ethiopia’s wheat export dream a reality,” he said.

Yahaya highlighted the role of CIMMYT in improving Ethiopia’s wheat production; around 70 percent of varieties grown in the country come from the organization’s germplasm. He also praised Ethiopia’s tax free imports on agricultural machineries and strong extension system, saying that other countries could learn from the success of these initiatives.

The interview took place at a working group on mechanization organized by the Green Innovation Centers (GIC) and CIMMYT to promote the use of machinery in agriculture.

India will have record wheat production, must plan for export, says Arun Kumar Joshi

A scientist from the International Maize and Wheat Improvement Center (CIMMYT) spoke to The Hindu about current challenges in wheat cultivation in India.

Arun Kumar Joshi, CIMMYT Country Representative for India, CIMMYT Regional Representative for South Asia and Managing Director of the Borlaug Institute for South Asia (BISA), predicted a bumper year for wheat in India.

“The feedback so far I am getting is that there will be record production of wheat,” he said. “The reason is that the area of cultivation has increased. According to government estimates, wheat has been sown in more than 34 million hectares so far in this rabi season.”

Reasons for this include no current threat from locusts or diseases, appropriate levels of soil moisture and humidity, and farmers shifting to planting crops earlier, explained Joshi.

Xiplomacy: China, LAC countries embrace new era of win-win cooperation

An article in the Big News Network examines opportunities for collaboration between China and Latin America and the Caribbean, referencing work between China and the International Maize and Wheat Improvement Center (CIMMYT).

Bram Govaerts, director general of CIMMYT, said the collaboration with China can be regarded as one of the mutually beneficial examples of working together to safeguard the world’s food security.

CIMMYT and China together can be partners,” said Govaerts. “CIMMYT can work with China for new wheat varieties that can fight climate change, for new maize varieties that can sustain new diseases.”

Pravasi Bharatiya Samman winner, scientist Dr Ravi Singh is working towards food security for all

As he retires from his illustrious career, a new interview with Ravi Singh, Head of Global Wheat Improvement at CIMMYT, by the Global Indian reveals his motivations for becoming a scientist and his desire to ensure people all over the world had access to food.

“I retired quite recently, however, I have a lot to do. I wish to mentor young scientists about on how to increase food production. I also look forward to working on several high-profile projects with farmers to tackle future issues they might face due to the climate changes on a crop like wheat,” shares the scientist.

Singh was honored with the Pravasi Bharatiya Samman by the Government of India in January 2021, recognizing his outstanding achievements by non-resident Indians, persons of Indian origin, or organizations or institutions run by them either in India or abroad. He received this for his role in the development, release, and cultivation of more than 550 wheat varieties over the past three decades.

Singh has also been included among the top one percent of highly-cited researchers, according to Clarivate Analytics-Web of Science every year since 2017.

How a new generation of women are changing wheat science

by Krisy Gashler 

For Charlotte Rambla, winning the 2022 Jeanie Borlaug Laube Women in Triticum (WIT) Early-Career Award was an “incredible, unreal experience.”

Each year, the Borlaug Global Rust Initiative (BGRI) honors five to six female early-career wheat researchers with the WIT award in recognition of scientific excellence and leadership potential. With the award, women scientists receive leadership training and professional development opportunities meant to support them as they join the community of scholars who are fighting hunger worldwide.​

“The training I’ve received with this award has been one of the best experiences of my professional life,” said Rambla, an Italian native who recently completed her Ph.D. at the Queensland Alliance for Agriculture and Food Innovation in Australia and has begun a postdoctoral appointment at the Salk Institute for Biological Studies. “Meeting these incredible women working in the same field, sharing our knowledge and experiences, it felt like we belonged together and were working toward one shared purpose; We are all joined by this same passion for agriculture and science.”

The 2022 awards honored six early-career scientists from Morocco, Indonesia, Ethiopia, Italy, Pakistan and China. Since 2010, the WIT awards have recognized 66 early-career scientists from 29 different countries. The training and development opportunities offered to each year’s cohort varies, based on the needs and interests of the winners, said Maricelis Acevedo, director for science for the BGRI, research professor in the Department of Global Development at Cornell University, and a 2010 WIT awardee. The 2022 WIT cohort visited the World Food Prize Foundation in October, just before the foundation announced the winner of this year’s World Food Prize, widely considered the Nobel Prize for food and agriculture.

“The role of the WIT award is to recognize emerging scientific leadership and provide training and support for women working in wheat to create a cohesive group of hunger-fighters who have the skills to lead the next generation of scientists and create the solutions that we need at such a critical time,” Acevedo said. “As these women receive the award, we hope that they continue to support other women and other early-career scientists, and to train their students in a more open, diverse network.”

Meriem Aoun, a 2018 WIT awardee and native of Tunisia, was a postdoctoral associate at Cornell University when she won her award. Her cohort received a month-long training at the International Maize and Wheat Improvement Center (CIMMYT) – the center where Norman Borlaug did the research that earned him the 1970 Nobel Peace Prize –  and attended the 2018 international BGRI conference in Morocco. Aoun believes that the WIT award supported her professional career development and gave her the opportunity to connect with other WIT winners from many countries.  “I am thrilled to see more and more ambitious and career-interested wheat scientists and that our community of WIT winners is growing each year,” she said.

Now an assistant professor of wheat pathology at Oklahoma State University (OSU), Aoun studies the genetics of disease resistance to wheat pathogens. She is a key member of OSU’s wheat improvement team developing disease-resistant wheat varieties suited for Oklahoma and the Southern Great Plains of the U.S.

For 2013 winner and Swiss-Argentinian Sandra Dunckel, the fact that BGRI chooses a cohort of women each year, rather than a single winner, is one of the strengths of the award. Now head of Breeding Barley, Special Crops and Organics at KWS Group, a multinational seed company headquartered in Germany, Dunckel said the networking opportunities were among the most beneficial aspects of her WIT award training.

“There is this group of women who are working on a common goal, and even if you aren’t in touch for several years, you can contact someone from your year, or really any year, and say, ‘Hello, fellow WIT winner, I’m looking for a breeder with great potential for one of my teams, can you recommend someone, or  I need help with this question.’ It’s always there to fall back on,” she said.

Dunckel won her WIT award while completing her PhD at Kansas State, then worked for two years as a wheat breeder in Australia before moving to her current role at KWS, where she oversees nine breeding teams across Europe who are working to develop new barley, peas, oats and protein crop varieties that are more tolerant to drought and heat, have desired quality profiles and can be grown more sustainably globally.

Paula Silva, a 2020 WIT awardee, also won her award while completing her PhD at Kansas State. She has since returned to her native Uruguay, where she leads the breeding team developing disease resistant varieties of barley and wheat for Uruguay’s National Institute of Agricultural Research (INIA). From 2019-2022, she coordinated breeding efforts with CIMMYT by leading the Precision field-based Phenotyping Platform (PWPP) for Multiple Resistance to Wheat Diseases.

One of the purposes of the WIT award is to help achieve gender parity among wheat scientists, and Silva said she believes the award “is playing a big part in building gender equality.”

Silva said that as a student, she was encouraged to apply for the WIT award by Sarah Evanega, who, along with Ronnie Coffman, international professor emeritus of plant breeding and genetics at Cornell, lobbied for the establishment of the WIT award. The BGRI now annually presents WIT honors to early-career scientists and a mentor award for excellence in advising of women working in wheat and its nearest relatives.​

“Sarah was always advocating for young, female participation,” Silva said. “I remember her counting how many females there were in conference pictures, and I do that now, too. You can see, year by year, the female representation gets bigger and bigger.”

Full gender equality in science is still lacking, but progress is being made. The gains are seen in wider perspectives that challenge orthodoxy and improve scientific possibilities.

“The WIT awards are a fantastic way to recognize and support emerging leaders in our community. The impressive cohort of past and present WIT recipients are actively contributing to global efforts to improve crop production and food security,” said Alison Bentley, who now leads the Global Wheat Program at CIMMYT.

Part of Acevedo’s leadership role for BGRI is helping choose each year’s winner, as part of a panel that includes previous WIT awardees and globally recognized wheat scientists, and working with each cohort to develop appropriate training opportunities. Acevedo said as she progressed in her career, she realized how important it was to help young female scientists not only with traditional training and networking opportunities, but also with leadership, communication, and work-life balance.

“It’s really tough to be an isolated scientist: science can be very individualistic. It can be competitive. As women in science, we feel particularly isolated because a lot of our colleagues are males. So you may feel like, ‘This is only happening to me, I’m the only one struggling with this,’” Acevedo said. “In these trainings, we celebrate professional and personal successes but also share  our challenges, normalize struggles, and find support. As we think about a more collaborative and open science, we need to be talking more about humbleness, the positive impact of recognizing and making peace with weakness, and seeking support from one another to thrive as a diverse research community.”

The negative effects of climate change on food systems are felt across political boundaries, so creating sustainable remediation steps are best accomplished through global collaboration. In that spirit, the International Maize and Wheat Improvement Center (CIMMYT) and the Chinese Academy of Agricultural Sciences (CAAS) convened the China-CIMMYT Workshop on Climate Change & Food Crops Production on December 6, 2022.

Participants included principal investigators of China’s National Key Technology Research and Development Program, representatives of Chinese agricultural universities, CIMMYT scientists and representatives from a variety of international organizations. The agenda featured discussions regarding research priorities, efforts to establish best practices in classifying and prioritizing climate risks and identifying potential crucial points for future cooperation between CIMMYT and China.

After the welcome address from Wheat Breeder and Country Representative for China Zhongzhu He, Thomas Lumpkin, CIMMYT Director General Emeritus provided the introduction to global climate issues and their effects on agriculture, particularly staple crops like wheat.

“All climate change mitigation strategies must account for their effect on food production systems, the aim of this convening was to facilitate discussions among climate change scientists, crop breeders and agronomists,” said Lumpkin. “Global issues require global solutions and so collaboration among institutions is pivotal.”

Tek Sapkota, CIMMYT Agricultural Systems and Climate Change Scientist, presented a framework for quantifying GHG emissions and mitigation potential for food systems, key research objectives of the One CGIAR initiative MITIGATE+, an initiative aimed to reduce annual global food systems emissions by 7% by 2030.

Three other CIMMYT scientists presented at the workshop. Wei Xiong, Senior Scientist, Crop Modeler, focused on genotype-environment interactions and its implication on breeding. Urs Schulthess, Remote Sensing Scientist, presented state-of-the-art results on the effects of temperature and vapor pressure deficit on radiation use efficiency of wheat. Huihui Li, Scientist, Quantitative Geneticist, discussed expanding genome wide association mapping and genomic selection to include climatic factors, highlighting novel methods to bring genes and climate together to accelerate breeding cycles.

In the workshop’s closing remarks, Wei reiterated CIMMYT’s commitments to continued collaboration with Chinese institutions and outlined next steps, such as CIMMYT’s commitment to increasing global agricultural resilience via novel research, partnerships, and increased engagement. Wei also detailed methods to identify new mechanisms and funding channels to promote global cooperation, such as One CGIAR initiatives and funding from national partners, including the CAAS.

Closing the investment gap for sustainable agriculture

The conflict between Russia and Ukraine has impacted exports of wheat, barley and fertilizers, affecting food security in many regions that rely heavily on imports to access these products. The UN Food and Agricultural Organization (FAO) and the World Food Programme predict that acute food insecurity will affect up to 205 million people by early 2023, with conditions deteriorating further in 19 countries.

Redesigning agricultural systems to solve this challenge must also take climate change into account: research published in Nature Food suggests that food systems cause a third of global greenhouse gas (GHG), while use and misuse of fertilizers, pesticides, energy, and water damages biodiversity.

The private sector is missing out on opportunities to invest in the agricultural sector and be part of the solution due to the challenges of putting a price on something like ‘protecting biodiversity’.

Director of CIMMYT’s global wheat program Alison Bentley says that while overseas development assistance and national governments provide significant support to the organization, private finance does play a role. “We have some really nice collaborations with the private sector, which allow us to access technology. The private sector, in the space of plant genetics and plant breeding, has pioneered some methodologies and technologies,” she tells GTR.

Exotic wheat DNA helps breed ‘climate-proof’ crops

A new study has determined that wheat with exotic DNA from wild relatives benefits from up to 50 percent higher yields in hot weather, compared with elite lacks lacking these genes.

The study by the International Maize and Wheat Improvement Center (CIMMYT) and the Earlham Institute examined how exotic alleles contribute to wheat heat tolerance in different field conditions based on field trials in Sonora, Mexico.

“Crossing elite lines with exotic material has its challenges,” said Matthew Reynolds, co-author of the study and leader of Wheat Physiology at CIMMYT. “There’s a well-recognized risk of bringing in more undesirable than desirable traits, so this result represents a significant breakthrough in overcoming that barrier and the continued utilization of genetic resources to boost climate resilience.”

These results can be used to improve crop resilience and food security in the face of the challenges posed by climate change, as well as emphasizing the importance of genetic diversity in key crops where selective breeding has reduced adaptability.
