AMES, IOWAâThe Council for Agricultural Science and Technology (CAST) has announced the 2023 Borlaug CAST Communication Award goes to Alison Bentley.
While Bentley is known for her global research on wheat genetics, she is also recognized for her proficiency in science communication. Bentley has a passion for delivering practical applications from innovation to farmers, extensive reach through communicating and influencing, and mentoring and support of individuals and community efforts. Bentley’s exceptional work in raising awareness about the importance of wheat as a food crop is also evidenced by her wide-ranging list of communication activities.
In 2022 alone, Bentley delivered 20 scientific presentationsâincluding five international keynote talks and 15 additional invited talks. Bentley focused her communication efforts around two major areas. The first area was her rapid, science-led response to the impact of the Russian/Ukraine war on global wheat production through a communication article in Nature, followed with a social media campaign and numerous presentations and invited policy briefings. Her second area of focus was a major communications campaign by initiating and leading the Women in Crop Science network. This network was developed to address key issues such as the promotion and championing of females throughout their research careers, creating equal opportunities, and increasing visibility of members.
The extensive breadth of Bentleyâs outreach ranges from classic science presentations and open access articles to blogs, podcasts, YouTube videos, and Twitter campaigns. All these formats demonstrate her commitment to science communication and reaching as wide an audience as possible in an accessible way to engage with important, current topics regarding wheat supplies and plant breeding.
The official presentation of the award will take place at a special side event during the World Food Prize Borlaug Dialogue event in Des Moines, Iowa, in October. The Borlaug CAST Communication Award honors the legacy of Norman Borlaug, a Nobel Prize winner and author of the first CAST publication, and Dr. Charles A. Black, the first executive vice president of CAST. It is presented annually for outstanding achievement by a scientist, engineer, technologist, or other professional working in the agricultural, environmental, or food sectors for contributing to the advancement of science through communication in the public policy arena.

The International Maize and Wheat Improvement Center (CIMMYT) is an international organization focused on non-profit agricultural research and training that empowers farmers through science and innovation to nourish the world in the midst of a climate crisis. Applying high-quality science and strong partnerships, CIMMYT works to achieve a world with healthier and more prosperous people, free from global food crises and with more resilient agri-food systems. CIMMYTâs research brings enhanced productivity and better profits to farmers, mitigates the effects of the climate crisis, and reduces the environmental impact of agriculture.
CIMMYT is a member of CGIAR, a global research partnership for a food secure future dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources.
Public and private crop research organizations worldwide have worked behind the scenes for decades, bolstering the resilience of staple crops like maize and wheat to fight what is shaping up to be the battle of our time: feeding humanity in a biosphere increasingly hostile to crop farming.
In the case of wheat â which provides some 20% of carbohydrates and 20% of protein in human diets, not to mention 40% of total cereal exports â harvests spoiled by heat waves, droughts, and crop disease outbreaks can send food prices skyrocketing, driving world hunger, poverty, instability, human migration, political instability, and conflict.
Century-high temperature extremes and the early onset of summer in South Asia in 2022, for example, reduced wheat yields as much as 15% in parts of the Indo-Gangetic Plains, a breadbasket that yearly produces over 100 million tons of wheat from 30 million hectares of crop land.
Around half the worldâs wheat crop suffers from heat stress, and each 1 °C increase in temperature reduces wheat yields by an average 6%, according to a 2021 review paper âHarnessing translational research in wheat for climate resilience,â published in the Journal of Experimental Botany, which also outlines nine goals to improve the climate resilience of wheat.

Droughts and shrinking aquifers pose equally worrying threats for wheat, said Matthew Reynolds, a wheat physiologist at the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the study. âWater availability is the biggest factor influencing potential yield in a majority of wheat environments globally,â Reynolds explained. âStudies predict severe water scarcity events for up to 60% of the worldâs wheat-growing areas by the end of this century.â
Science and sources to toughen wheat
Along with modernized, more diverse cropping systems and better farm policies, more resilient varieties are crucial for sustainable wheat production, according to Reynolds and a wheat breeder colleague at CIMMYT, Leo Crespo, who added that breeders have been working for decades to stiffen wheatâs heat and drought tolerance, long before climate change became a buzzword.
âBreeding and selection in diverse environments and at targeted test sites characterized by heat and natural or simulated drought has brought farmers wheat varieties that perform well under both optimal and stressed conditions and weâre implementing new technologies to speed progress and lower costs,â said Crespo, mentioning that the Centerâs wheat nurseries SAWYT and HTWYT target semi-arid and heat-stressed environments respectively and are sent yearly to hundreds of public and private breeders worldwide through the International Wheat Improvement Network (IWIN). “Retrospective analysis of IWIN data has shown that heat tolerance has been increasing in recent years, according to a 2021 CIMMYT study.”
âClimate change is a serious driver of potential disease epidemics, since changeable weather can increase selection pressure for new virulent pathotypes to evolve,â said Pawan Singh, a CIMMYT wheat pathologist. âWe must be ever vigilant, and the IWIN is an invaluable source of feedback on potential new disease threats and changes in the virulence patterns of wheat pathogens.â
In the quest to improve climate resilience in wheat, CIMMYT âpre-breedingâ â accessing desired genetic traits from sources like wheatâs grassy relatives and introducing them into breeding lines that can be crossed with elite varieties â focuses on specific traits. These include strong and healthy roots, early vigor, a cool canopy under stress, and storage of water-soluble carbohydrates in stems that can be used as stress intensifies to complement supplies from photosynthesis, as well as an array of traits that protect photosynthesis including âstay-greenâ leaves and spikes and pigments that protect the delicate photosynthetic machinery from oxidative damage caused by excess light.

Though elite breeding lines may contain genetic variation for such traits, in pre-breeding researchers look further afield for new and better sources of resilience. The vast wheat seed collections of CIMMYT and other organizations, particularly seed samples of farmer-bred heirloom varieties known as âlandraces,â are one potential source of useful diversity that cutting-edge genetic analyses promise to help unlock.
Rich diversity for wheat is still found in farmersâ fields in India, in the northern states of the Himalayan region, the hill regions, and the semi-arid region of Rajasthan, Gujarat, Karnataka. The landraces there show tolerance to drought, heat, and saline soils.
The so-called âsynthetic wheatsâ represent another plentiful source of resilience genes. Synthetics are the progeny of crosses of tetraploid wheat (having four chromosomes, like the durum wheat used for pasta) with wild grass species. CIMMYT and other organizations have been creating these since the 1980s and using them as bridges to transfer wild genes to bread wheat, often for traits such as disease resistance and heat and drought tolerance.
Lines with new sources of heat- and drought-tolerance from CIMMYTâs pre-breeding are also distributed to public and private breeders worldwide via the IWIN for testing as the Stress Adapted Trait Yield Nurseries (SATYNs), according to the paper. These special nurseries are grown by national and private breeders throughout South Asia, for example in Afghanistan, Bangladesh, India, Iran, Nepal, and Pakistan. Lines from the nursery have on occasion been released directly as varieties for use by farmers in Afghanistan, Egypt, and Pakistan.
A critical challenge in pre-breeding is to identify and keep desirable wild genes while culling the undesirable ones that are also transferred in crosses of elite breeding lines with landraces and synthetics. One approach is through physiological pre-breeding, where complementary crosses are made to improve the crop performance under drought and heat stress. The second approach is using genomic prediction, on the basis of seeds, or accessions, in the gene bank collection that have gone through genomic and phenotyping analysis for target traits such as heat and drought tolerance. These approaches can also be combined to boost the speed and effectiveness of selecting strong varieties.
Breeding revolutions
Wheat breeding is being revolutionized by advances in âhigh-throughput phenotyping.â This refers to rapid and cost-effective ways to measure wheat performance and specific traits in the field, particularly remote sensing â that is, crop images taken from vehicles, drones, or even satellites. Depending on the wavelength of light used, such images can show plant physiochemical and structural properties, such as pigment content, hydration status, photosynthetic area, and vegetative biomass. Similarly, canopy temperature images from infrared photography allow detection for crop water status and plant stomatal conductance. Â âSuch traits tend to show better association with yield under stress than under favorable conditionsâ, said Francisco Pinto, a CIMMYT wheat physiologist who is developing methods to measure roots using remote sensing. âA remotely sensed âroot indexâ could potentially revolutionize our ability to breed for root traits, which are critical under heat and drought stress but have not been directly accessible in breeding.â
Innovative statistical analysis has greatly increased the value of field trials and emphasized the power of direct selection for yield and yield stability under diverse environments.
Initial results from genomic selection programs, particularly where combined with improved phenotyping techniques, also show great promise. The potential benefits of combining a range of new technologies constitute a valuable international public good.
New initiatives
Launched in 2012, the Heat and Drought Wheat Improvement Consortium (HeDWIC) facilitates global coordination of wheat research to adapt to a future with more severe weather extremes, specifically heat and drought. It delivers new technologies â especially novel wheat lines  to wheat breeders worldwide via the International Wheat Improvement Network (IWIN), coordinated for more than half a century by CIMMYT.
HeDWIC is supported by the Foundation for Food and Agriculture Research (FFAR) and is part of the Alliance for Wheat Adaption to Heat and Drought (AHEAD), an international umbrella organization set up by the Wheat Initiative to bring the wheat research community together and to exchange new germplasm, technologies and ideas for enhancing tolerance to heat and drought.

Harisankar Nayak, a CIMMYT supported PhD student, received significant honors from the Government of India for his PhD thesis. The Indian Council for Agricultural Research (ICAR) – Indian Agricultural Research Institute (IARI) recognized Nayak’s exceptional academic performance and thesis work during the 61st convocation ceremony held in New Delhi on February 24, 2023. The Vice President of India, Shri Jagdeep Dhankhar, presided over the ceremony. Nayak was awarded the IARI Merit medal for his thesis, âMachine learning evidence-based agronomic practices for higher yield and lower emission in rice-wheat system,â published in the esteemed journal Field Crops Research.
Nayak’s research involved comparing multiple machine learning methods to identify the primary drivers and causes of wheat yield variability in northwestern India. His findings provide important methodology to identify variables involved when one farm’s yield is less than a similar farm in the same area. With these variables classified, policymakers, government ministries, and farmers themselves can take steps to raise yield, sustainably, across the entire north-western Indo-Gangetic Plain.
Timothy Krupnik, Country Representative for Research and Partnerships and Systems Agronomist at CIMMYT-Bangladesh, and Nayak’s PhD supervisor from CIMMYT, expressed his pride in Nayak’s achievements. âI saw first-hand how much work he put into his research, and he richly deserves this honor. The same was opined by Dr C. M. Parihar, Nayakâs supervisor from IARI, Dr. M.L. Jat, former principal scientist, CIMMYT-India and Dr T B Sapkota, senior scientist, Agricultural System/Climate Change, CIMMYT. In addition, this is an excellent example of the capacity development work arising from CIMMYT’s collaborations with ICAR and IARI.â
Nayak also led research examining the sustainability of rice production in the same area of India, which determined that nitrogen use could be reduced without impacting rice yields. “To be recognized by ICAR and IARI, among many other worthy students, is a great honor,” said Nayak. “CIMMYT provided crucial material support, helping me facilitate my research. Just as important were the opportunities to collaborate with CIMMYT scientists.” Nayak’s work is vital for addressing the challenges posed by a changing climate and feeding a growing population.
Like other crops, wheat â which makes up 20 percent of the human diet â is affected by threats to the global food system from persistent population growth and economic and climate pressures. These challenges are further exacerbated by the fallout from the COVID-19 pandemic and the war in Ukraine. There is an urgent need to prioritize climate resilient wheat varieties to protect this food staple.
Some five years after HeDWIC was launched in 2014 to incorporate the most advanced research technologies into improving heat and drought tolerance of wheat, the Intergovernmental Panel on Climate Change reported that climate change was having an impact on food security through increasing temperatures, changing precipitation patterns and greater frequency of extreme weather events in its Special Report on Climate Change and Land.
âWhile some areas are becoming more conducive to wheat growing, crop yields are suffering in other regions around the world traditionally known as bread baskets,â said wheat physiologist Matthew Reynolds, who leads HeDWIC at the International Maize and Wheat Improvement Center (CIMMYT).
âWheat is one of our fundamental crops, and we must spare no effort in protecting it from current and future challenges,â said Saharah Moon Chapotin, FFAR executive director. âGlobal collaborations are necessary to address global concerns, and these grants are bringing together international teams to share and build the science and research that will ensure the stability of this crop.â
To boost new ideas in âclimate-proofingâ crops, HeDWIC conducts virtual meetings that include all awarded research teams to take advantage of the collective global expertise in heat and drought resilience, leading to cross-pollination of ideas and further leverage of resources and capabilities.
In March, Reynolds led in-person discussions with some of the collaborating researchers at CIMMYTâs experimental research station on the outskirts of Ciudad Obregon, a city in Mexicoâs Sonoran Desert, during CIMMYTâs annual Visitorsâ Week.
Projects awarded in 2022
Exploring the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat (FluoSense4Wheat)
âThe HeDWIC mini proposal allows us to explore the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat. The controlled irrigation conditions for wheat grown in Obregon give us the opportunity to quantify photosynthesis by fluorescence while drought develops. Detecting a drought-specific fluorescence response and/or the interaction between active and passive fluorescence is relevant for breeding selecting purposes as well as large spatial scale detection of drought by monitoring the plant.â â Onno Muller, Forschungszentrum JĂźlich, Institute of Bio- and Geosciences, Germany
Physiological basis of amelioration of heat stress through nitrogen management in wheat
âHeat stress during grain filling can restrict the availability of carbohydrates needed for grain development. India has been experiencing sudden spikes in both minimum and maximum temperatures by 3 to 5 degrees above normal from late-February onwards, which is an important time for wheat grain-filling and has resulted in declining wheat productivity. Our team is examining the ability of pre-flowering nitrogen applications to support biomass accumulation and overcome the grain-filling source (carbohydrate) limitation during heat spikes. If successful, the results could have broad-reaching benefits given that farmers are familiar with and well-skilled in using nitrogen applications regimes in crop management.â â Renu Pandey, Division of Plant Physiology, Indian Agricultural Research Institute
Can reproductive development be protected from heat stress by the trehalose 6-phosphate pathway?
âThe HeDWIC funding provides a unique opportunity to test how the regulatory sugar, trehalose 6-phosphate (T6P) can protect wheat yields against increasingly common chronic and acute heat stress events. We have already shown that T6P spray increases wheat yields significantly in field conditions under a range of rainfall in wet and dry years. With increasing likelihood of heat stress events in the years ahead, in unique facilities at CIMMYT, we will test the potential of T6P to protect reproductive development from catastrophic yield loss due to chronic and acute heat.â â Matthew Paul, Rothamsted Research, UK
Investigating tolerance of heat resilient wheat germplasm to drought
âOver the last decade, we have developed heat tolerant wheat germplasm at the University of Sydney that maintains yield under terminal heat stress. In our new HeDWIC project, this material will be tested under combined drought and heat stress under field conditions. This will provide plant breeders with highly valuable information on field tested germplasm for use in accelerated breeding programs targeting combined heat and drought tolerance. The work is critical for future food security considering the inextricable link between temperature and plant water demand, and the increased frequency and intensity of heat and drought events under projected climate change.â â William Salter, University of Sydney, Australia
Novel wheat architecture alleles to optimize biomass under drought
âWheat Rht-1 dwarfing genes were an essential component that led to spectacular increases in grain yields during the Green Revolution. Although Rht1 and Rht2 are still used widely in wheat breeding 50 years after they were introduced, they are suboptimal under drought conditions and are often associated with a yield penalty. Using a more extensive range of Rht-1 dwarfing alleles that were developed at Rothamsted, we will introduce them into CIMMYT germplasm to optimize biomass and ultimately increase grain yields under drought stress.â â Steve Thomas, Rothamsted Research, UK

Scientists at the International Maize and Wheat Improvement Center (CIMMYT) are helping to scale up wheat production and productivity in Malawi.
The political conflict between Russia and Ukraine has disrupted food supply chains globally and Malawiâs wheat supply has been adversely affected. As a response, Pyxus Trading, the biggest agribusiness private company in Malawi, has endeavored to partner with CIMMYT to accelerate the growth of wheat production in the country.
At a recent visit by CIMMYTâs Director General Bram Govaerts, the executive management of Pyxus provided detailed updates of how CIMMYT has facilitated access to 100 improved wheat varieties now undergoing trials in Malawi. The visit was part of the Accelerated Innovation Delivery Initiative (AID-I), a new project funded by the United States of Agency for International Development (USAID).
Attending the Pyxus field visit was United States Department of State Special Envoy for Global Food Security Cary Fowler, Dina Esposito, Assistant to the Administrator at USAID Bureau of Resilience and Food Security, and other USAID staff.
Speaking at a field tour this January at the Pyxus farm headquarters, Commercial Manager John Gait expressed the importance of achieving self-sufficiency in countries like Malawi.
âItâs become very apparent with the global supply chain disruptions of wheat and related commodities that countries like Malawi should rise to a level of self-sufficiency for strategic commodities such as wheat,â Gait said. âThrough the help of CIMMYT, we managed to obtain materials for 100 varieties which we have put under trial. Our objective is to select varieties that are most adapted to our agroecology and provide us with satisfactory yields and grain quality sufficient for our processing ambitions.â
CIMMYT Sustainable Agrifood Systems (SAS) Director Sieg Snapp affirmed CIMMYTâs support for private sector companies like Pyxus.
âWhen they told me they were searching for high performing genetic materials I told them about the Global Wheat Program and how such material could easily be obtained from our headquarters in Mexico,â Snapp said. âI immediately facilitated linkages between Pyxus and CIMMYT headquarters which saw the quick delivery of the varieties. Considering that it was quite recent, I am impressed to see that the trials are already so well established.â

Achieving global food security will require cooperation and collaboration between partners from different sectors. One of CIMMYTâs strategic thrusts is to encourage public-private partnerships where national governments can leverage on the competencies and capabilities of the private sector.
âWe aim to be catalytic in all our functions. We believe we have a critical role in ensuring that countries like Malawi have access to the best genetics to ensure that they meet their food requirements. I am happy Pyxus identified us a strategic partner to work with in their wheat program, and through working hand in hand with the government and other key players, the quest to achieve food self-sufficiency can have a shortened pipeline,â Govaerts said.

In addition to witnessing the wheat trials, Govaerts received a tour of the entire Pyxus operations which included the groundnut and forestry operations. Pyxus staff each took turns explaining the various business models the company was employing to contribute to Malawiâs export earnings and food security.
As a commitment to help Malawi realise increased wheat production, CIMMYT will be closely following the Pyxus trials and providing technical support to ensure that the best varieties adopted are rapidly scaled.

Representatives from Australian Centre for International Agricultural Research (ACIAR) and Bangladesh Agricultural Research Council (BARC) paid a visit to Bangladesh to see the valuable work of the Precision Phenotyping Platform (PPP).
PPP was established in response to the devastating wheat blast disease, which was first reported in the country in 2016.
Technical and financial support from the International Maize and Wheat Improvement Center (CIMMYT), the Australian Commission for International Agricultural Research and the Australian Centre for International Agricultural Research, along with other funders, has contributed to the effort to combat the disease.
This is achieved by generating precise data for wheat blast resistance in germplasm in Bangladesh, as well as other wheat growing countries. This PPP has been used to screen elite lines and genetic resources from various countries.
On February 16 and 17, 2023, two groups of national and international delegations visited the BWMRI-CIMMYT collaborative research platform PPP at the BWMRI regional station in Jashore, Bangladesh.
The first group was made up of representatives from both the Australian Commission for International Agricultural Research and the Australian Centre for International Agricultural Research. This included seven commissioners under the direction of Fiona Simson, along with ACIAR senior officials from Australia and India.
The other group was from BARC, which was led by Executive Chairman Shaikh Mohammad Bokhtiar, along with Golam Faruq, Director General of BWMRI, and Andrew Sharpe, Bangabandhu Research Chair, Global Institute of Food Security (GIFS), University of Saskatchewan in Canada.
Both delegations were welcomed by Muhammad Rezaul Kabir, the Senior Wheat Breeder at BWMRI. Kabir gave a brief presentation about the platform and other wheat blast collaborative research programs in the seminar room.
The delegations then went to the PPP field, where BWMRI researchers Kabir and Robiul Islam, as well as CIMMYT researcher Md. Harun-Or-Rashid, explained further information about the BWMRI-CIMMYT collaborative research. Both commissioners and delegates appreciated seeing the work being conducted in person by the national and international collaborations of BWMRI and CIMMYT on wheat blast research.

âIt is important, innovative work, that is affecting not only Bangladesh but many countries around the world that are now starting to be concerned about the impacts of wheat blast,â commissioner Simson said. âThis study is very important for Australia and we are pleased to be contributing to it.â
Lindsay Falvey, another commissioner, added, âThis is a wonderful experiment, using high-level science and technologies to combat wheat blast in Bangladesh. The experiment is well-planned. Overall, it is an excellent platform.â
ACIAR delegate Eric Huttner added to the praise for the project. âThe platform is performing extremely well for the purpose of evaluating lines, resistance to the disease and thatâs very useful for Bangladesh and rest of the world,â he said. âThis is a gift that Bangladesh is giving to the neighboring countries to protect wheat.â
The delegates pledged to share their expert advice with the Minister of Foreign Affairs in Bangladesh in order to increase investments and improve facilities for agricultural research programs in the country.

âThis is an excellent work,â Executive Chairman of BARC, Bokhtiar said. âWe can get more information from screening activities by using bioinformatics tools and training people through the BARC-GIFS program.â
Pawan Kumar Singh, Head of Wheat Pathology at CIMMYT-Mexico and Project Leader, coordinated the visits virtually and expressed his thanks to the delegations for their visit to the platform. This PPP, within a short span of few years, has been highly impactful, characterizing more than 15,000 entries and releasing several resistant varieties in countries vulnerable to wheat blast.
The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the worldâs 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 â stem, stripe and leaf â 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:Â

On March 2, the China-Pakistan Joint Wheat Molecular Breeding International Lab (“Joint Lab”) was launched, funded by the Science and Technology Partnership Program, Ministry of Science and Technology of China, with the joint support from China‘s Ministry of Agriculture and Rural Affairs, National Agriculture Research Center of Pakistan and the International Maize and Wheat Improvement Center (CIMMYT).
The joint lab aims to develop new varieties with high yield and resistance to disease, enhancing breeding capacity and wheat production in Pakistan, where wheat is the largest food crop.
To mark International Womenâs 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 â careers involving field, lab, data, and socioeconomic work â 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.
I have enjoyed being able to make some first small changes â who knew sanitary facilities would turn out to be a recurring topic! â 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 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.
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.
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.”
“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,â 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.
David Omar Gonzalez Dieguez is a Post-Doctoral Fellow – Molecular Pre-Breeder in the Global Wheat Program at CIMMYT. He leads the application and integration of molecular tools in research and pre-breeding activities in wheat physiology.
In the research context, Dieguez focuses on the genetic basis of physiological traits related to yield components and climate resilience for yield potential, heat, and drought adaptation by performing GWAS analyses for gene/marker/QTL discovery and establishing marker validation for pre-breeding and breeding application to assist stacking of complementary physiological and agronomic traits.
In the pre-breeding context, Dieguez conducts the application and integration of genomic-assisted breeding tools (i.e. MAS/MABC and GS) at appropriate stages of the pre-breeding pipeline to support pre-breederâs decisions for selecting lines for yield potential and tolerance to heat and drought stress and for trait introgression.
