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.
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.

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.

In an interview, Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), highlights the challenges facing crop cultivation management and agricultural product trade in Mexico and the rest of the world.
“At present, one of the most pressing challenges [in Mexico] is water scarcity exacerbated by la Niña’s occurrence,” explains Govaerts. “The global average of freshwater consumption for food production is 70 percent. However, Mexico ranks 24 in a global Water Stress Index facing high levels of stress by consuming between 40 and 80 percent of water supplies available in any given year.”
The article explores successful local sustainable grain sourcing projects in Mexico, research into sustainable global agricultural development, genetically-modified crops and their connection to biodiversity, and soil health.

In the sultry spring-summer heat of Bihar, India, the landscape is yellow with wheat grains ready for harvest. Here, in Nagma village farmer Ravi Ranjan attends to his fields — mostly wheat, with some pulses in the adjoining plots. The harvest this year will be a little less than anticipated, he explains, as receding monsoon rains left the soil too moist to begin sowing on time.
Ranjan’s grandfather and father were both farmers who owned sizable land. His father used to say that the land was productive but required a lot of hands, sweat, and time to sustain the yields. Agriculture was all that the family had known and depended on for decades before Ranjan’s father left the sector for the civil service. After the early demise of his grandfather in 2003, and with his father in a secure government job, it fell to Ranjan to shoulder the responsibility of managing the family farm.
As a young man, Ranjan had sometimes helped his grandfather in the fields, but now, as the owner of a hydraulic mechanical service firm working hundreds of kilometers away in Chhattisgarh, he had never imagined becoming a farmer himself. Though reluctant to begin with, Ranjan decided there was no alternative but to take on the challenge and do his best, and while initially he had little success with the new venture, slowly and steadily he began to change the fortune of his inherited land.
Today Ranjan is one of the local area’s success stories, as a progressive and influential farmer with ties to the Cereal Systems Initiative for South Asia (CSISA) project. Researchers on the CSISA team have been working with farmers like him in the region for over a decade and are proud of the ongoing collaboration. Ranjan’s fields are regularly used as CSISA trial plots to help demonstrate the success of new technologies and conservation agriculture practices that can enhance productivity and sustainability. For example, in the 2021-2022 winter cropping season — locally known as Rabi — he harvested 6.2 tons per hectare – while a separate acre plot as demonstration site was harvested publicly with officials from CSISA and the Krishi Vigyan Kendra Network (KVK), JEEViKA, and farmers from neighboring villages for improving yield sustainably.
As India celebrates Kisan Diwas (Farmer’s Day) on December 23, we speak to Ranjan about his hopes for the future and the continuity of farming in his family after he hangs his boots.
Farming has seen a sea of change since your grandfather’s time. What do you think has been the most transformative change in the years you have been involved in farming?
I think using mechanized tools and technology to ensure good cropping practices has tremendously reduced manual work. Furthermore, today with innovations and digitization in agriculture science, farming is not just recognized as a noble profession, but also an enterprising one. I am happy I came into it right when things were changing for good. I have no regrets.
Though not by choice that I came into it, I am now fully invested and devoted to farming. From being an entrepreneur to farming, it has been a transformational journey for me. I am unsure whether my daughters — I have three, the eldest turns 18 next year — will choose to be involved in agricultural farming. But I will encourage and fully support them if they choose to take it up. After all, they will inherit the land after me.
Extreme climate effects are challenging agricultural practices and output. How are you preparing to reduce the impact of these in your fields?
It is worrying to see how extreme climatic effects can be challenging for agriculture, particularly for smallholder farmers in the region. Erratic rains, drought at times, and increasing temperatures have all harmed our cereal and vegetable farms and affected yield in wheat crops significantly. The adoption of new technologies like direct seeded rice (DSR) to avoid puddled rice transplanting, early wheat sowing (EWS) to avoid terminal heat at maturity, zero tillage technology (ZTT), and better-quality seeds, are interventions introduced and supported by CSISA and other agricultural organizations from the state that has helped combat some of these climate-induced problems.
In my own fields, I have also introduced proper irrigation systems to reduce the impact of limited water availability. I hope to stay ahead of the curve and make sure I am aware of all that is possible to keep my farm productive and sustainable.
How did you begin your association with CSISA? What has been your experience of working with them to make your agriculture resilient and productive?
I was initially approached by one of their scientists working in the area. And because of my interest, they slowly began informing me of various technologies I could try. With these technologies implemented in my field, the yield and productivity improved.
Soon after expanding my agriculture output, I got 50 acres of land on lease in the village to grow more crops like pulses, along with rice and wheat. Today, CSISA has started using my fields as their demonstration plots for new technologies and best practices, and to spread awareness and bring in more farmers from neighboring villages to encourage adoption.
CSISA and others call me a progressive and innovative farmer. I am proud that many farmers and other agricultural agencies in the area have appreciated our efforts to continue making agriculture productive and sustainable.
About CSISA:
Established in 2009, the Cereal Systems Initiative for South Asia (CSISA) is a science-driven and impacts-oriented regional initiative for increasing the productivity of cereal-based cropping systems. CSISA works in Bangladesh, India, and Nepal. CSISA activities in India focus on the eastern Indo-Gangetic Plains, dominated by small farm sizes, low incomes, and comparatively low agricultural mechanization, irrigation, and productivity levels.

Scientists from the All India Coordinated Research Project (AICRP) on Wheat and Barley, part of the Indian Council of Agricultural Research (ICAR), and the Mountain Research Centre for Field Crops at Sher-e-Kashmir University of Agricultural Sciences and Technology visited the International Maize and Wheat Improvement Center (CIMMYT) facility in Türkiye on November 14-17.
This trip was an extension of their visit to the Türkiye Akdeniz University, Antalya, under the ICAR-NAHEP overseas fellowship program. The trip to CIMMYT program in Türkiye was with the objective to get exposure to CIMMYT’s germplasm and other new developments in wheat improvement that may be helpful for wheat production in the Northern Hill zone of India, which grows wheat on around 0.8 million hectares.
Ajaz Ahmed Lone, Principal Scientist, Genetics and Plant Breeding at the Dryland Agricultural Research Station, and Shabir Hussain Wani, Scientist, Genetics and Plant Breeding and Principal Investigator, aimed to learn more about CIMMYT’s wheat improvement systems.
After a brief introduction on CIMMYT’s international and soil borne pathogens program in Türkiye by Abdelfattah Dababat, CIMMYT Country Representative for Türkiye and program leader, the visitors met with General Directorate of Agricultural Research and Policies (TAGEM) representative Fatma Sarsu and her team to discuss possible collaboration and capacity building between the two institutions.
Wheat improvement in Türkiye
Lone and Wani also visited the GenBank in Ankara to meet its head, Senay Boyraz Topaloglu, who gave a presentation about the GenBank and highlighted the site’s various facilities.
They then visited the Transitional Zone Agricultural Research Institute (TZARI) in Eskisehir, located in Central Anatolian Plateau of Türkiye, to hear about historical and current studies, particularly within the national wheat breeding program delivered by Head of the Breeding Department, Savas Belen. Belen briefed the visitors about the institute’s facilities, and the collaboration with CIMMYT scientists on wheat breeding activities and germplasm exchange.
Dababat and Gul Erginbas-Orakci, research associate at CIMMYT, presented an overview of soil borne pathogens activities in TZARI-Eskisehir.
Before the visitors departed to Konya, Director of TZARI, Sabri Cakir, welcomed the visitors in his office.
On the final day, the scientists were briefed about Bahri Dagdas International Agricultural Research Institute (BDIARI) through a presentation given by Murat Nadi Tas and Musa Turkoz. Bumin Emre Teke from the animal department presented a European project report on animal breeding, and Mesut Kirbas provided an overview of a European project on e-organic agriculture, as well as visits to the institute’s laboratory and field facilities and the newly established soil borne pathogens field platform.
Dababat said, “It was a fruitful short trip which enabled scientist from SKUAST-Kashmir and CIMMYT-Türkiye to share knowledge about wheat improvement activities and will give way to a road map for future research collaborations between the three institutions.”
Smallholder farmers, the backbone of food systems around the world, are already facing negative impacts because of climate change. Time to adapt climate mitigation strategies is not a luxury they have. With that in mind, the Agriculture Innovation Mission for Climate (AIM4C) facilitates innovation sprints designed to leverage existing development activities to create a series of innovations in an expedited timeframe.
At the UN COP27 in Egypt, AIM4C announced its newest round of innovation sprints, including one led by the International Center for Maize and Wheat Improvement (CIMMYT) to enable smallholder farmers to achieve efficient and effective nitrogen fertilizer management. From 2022 to 2025, this sprint will steer US $90 million towards empowering small-scale producers in Africa (Kenya, Malawi, Morocco, Tanzania, and Zimbabwe), Asia (China, India, Laos and Pakistan), and Latin America (Guatemala and Mexico).
“When we talk to farmers, they tell us they want validated farming practices tailored to their specific conditions to achieve greater productivity and increase their climate resilience,” said Sieg Snapp, CIMMYT Sustainable Agrifood Systems (SAS) program director who is coordinating the sprint. “This sprint will help deliver those things rapidly by focusing on bolstering organic carbon in soil and lowering nitrous oxide emissions.”
Nitrogen in China
Working with the Chinese Academy of Agricultural Sciences (CAAS), the sprint will facilitate the development of improved versions of green manure crops, which are grown specifically for building and maintaining soil fertility and structures which are incorporated back into the soil, either directly, or after removal and composting. Green manure can significantly reduce the use of nitrogen-based fertilizers, which prime climate culprits.
“There are already green manure systems in place in China,” said Weidong Cao from CAAS, “but our efforts will integrate all the work being done to establish a framework for developing new green manure crops aid in their deployment across China.”
Triple wins in Kenya
The Kenya Climate Smart Climate Project, active since 2017, is increasing agricultural productivity and building resilience to climate change risks in the targeted smallholder farming and pastoral communities. The innovation sprint will help rapidly achieve three wins in technology development and dissemination, cutting-edge innovations, and developing sets of management practices all designed to increase productive, adaption of climate smart tech and methods, and reduce greenhouse gas (GHG) emissions.
Agricultural innovations in Pakistan
The Agricultural Innovation Program (AIP), a multi-disciplinary and multi-sectoral project funded by USAID, led by CIMMYT, and active in Pakistan since 2015, fosters the emergence of a dynamic, responsive, and competitive system of science and innovation that is ‘owned’ by Pakistan and catalyzes equitable growth in agricultural production, productivity, and value.
“From its beginning, AIP has been dedicated to building partnerships with local organizations and, smallholder farmers throughout Pakistan, which is very much in line with the objectives and goal as envisioned by Pakistan Vision 2025 and the Vision for Agriculture 2030, as Pakistan is a priority country for CIMMYT. However, a concerted effort is required from various players representing public and private sectors,” said Thakur Prasad Tiwari, senior scientist at CIMMYT. “Using that existing framework to deliver rapid climate smart innovations, the innovation sprint is well-situated to react to the needs of Pakistani farmers. “
Policies and partnerships for innovations in soil fertility management in Nepal
The Nepal Seed and Fertilizer (NSAF) project, funded by USAID and implemented by CIMMYT, facilitates sustainable increases in Nepal’s national crop productivity, farmer income, and household-level food and nutrition security. NSAF promotes the use of improved seeds and integrated soil fertility management technologies along with effective extension, including the use of digital and information and communications technologies. The project facilitated the National Soil Science Research Centre (NSSRC) to develop new domain specific fertilizer recommendations for rice, maize, and wheat to replace the 40 years old blanket recommendations.
Under NSAFs leadership, the Ministry of Agriculture and Livestock Development (MOALD) launched Asia’s first digital soil map and has coordinated governmental efforts to collect and analyze soil data to update the soil map and provide soil health cards to Nepal’s farmers. The project provides training to over 2000 farmers per year to apply ISFM principles and provides evidence to the MOALD to initiate a balanced soil fertility management program in Nepal and to revise the national fertilizer subsidy policy to promote balanced fertilizers. The project will also build efficient soil fertility management systems that significantly increase crop productivity and the marketing and distribution of climate smart and alternative fertilizer products and application methods.
Public-private partnerships accelerate access to innovations in South Asia
The Cereal Systems Initiative for South Asia (CSISA), established in 2009, has reached more than 8 million farmers by conducting applied research and bridging public and private sector divides in the context of rural ‘innovation hubs’ in Bangladesh, India, and Nepal. CSISA’s work has enabled farmers to adopt resource-conserving and climate-resilient technologies and improve their access to market information and enterprise development.
“Farmers in South Asia have become familiar with the value addition that participating in applied research can bring to innovations in their production systems,” said Timothy Krupnik, CIMMYT systems agronomist and senior scientist. “Moreover, CSISA’s work to address gaps between national and extension policies and practices as they pertain to integrated soil fertility management in the context of intensive cropping systems in South Asia has helped to accelerate farmers’ access to productivity-enhancing innovations.”
CSISA also emphasizes support for women farmers by improving their access and exposure to improved technological innovations, knowledge, and entrepreneurial skills.
Sustainable agriculture in Zambia
The Sustainable Intensification of Smallholder Farming systems in Zambia (SIFAZ) is a research project jointly implemented by the UN Food and Agriculture Organization (FAO), Zambia’s Ministry of Agriculture and CIMMYT designed to facilitate scaling-up of sustainable and climate smart crop production and land management practices within the three agro-ecological zones of Zambia. “The Innovation Sprint can take advantage of existing SIFAZ partnerships, especially with Zambia’s Ministry of Agriculture,” said Christian Thierfelder, CIMMYT scientist. “Already having governmental buy-in will enable quick development and dissemination of new sustainable intensification practices to increase productivity and profitability, enhance human and social benefits while reducing negative impacts on the environment.”

Breeding is a vital part of the global agrifood system, enabling scientists to adapt crops to developing environmental factors, support improved crop management, and inform policy interventions on global food production. The challenge to crop breeding increases every year, as farmers experience more of the effects of climate change, while the population and food demand continue to rise.
Research by the International Maize and Wheat Improvement Center (CIMMYT) has determined that climate change is affecting the objectives, efficiency, and genetic gains of current plant breeding, causing limitations to the breeding approach of the next generation.
The study found that climate change necessitates a faster breeding cycle and must drive changes in breeding objectives by putting climate resilience as the top priority.
“The risk of multiple crop failure due to climate change is very real. Breeding must become more deterministic in terms of adaption if we are to avert food price-hikes, hunger, and social unrest,” said Matthew Reynolds, Distinguished Scientist and Head of Wheat Physiology at CIMMYT.
Challenges in developing climate-ready crops originate from the paradox between urgent breeding requirements prompted by climate change and the limited understanding of how different genotypes interact with the climates. Integrating multiple disciplines and technologies including genotyping, phenotyping, and envirotyping can contribute to the development and delivery of climate-adapted crops in a shorter timeframe.

Three scientists from the International Maize and Wheat Improvement Center (CIMMYT) are included in Clarivate’s 2022 Analysis of the most highly cited academic papers.
Maize Physiologist Jill Cairns, Distinguished Scientist and Head of Wheat Physiology Matthew Reynolds, and Biometrician José Crossa, all from CIMMYT, were recognized in the 2022 analysis.
This year, 7,255 Highly Cited Researcher (HCR) designations were issued to 6,938 individuals globally. The award is given to scientists with papers that rank in the top 1% by citations. Matthew was awarded for his contribution to scientific literature in plant and animal sciences, while José and Jill were awarded for their contributions to scientific literature across several fields of research (cross fields).
Of the world’s population of scientists and social scientists, Highly Cited Researchers are 1 in 1,000.
The analysis highlights disparities in the locations of top cited scientists. For example, 82.9% of recipients are from just ten countries and regions, out of a possible 70, and 71.4% are from the United States of America, China, the United Kingdom, Germany, or Australia. While the recognition is only given to individual scientists, Matthew, José, and Jill’s success is related to strong scientific collaborations worldwide.
SP Poonia is a Lead Researcher with CIMMYT’s Global Wheat Program and Sustainable Agrifood Systems (SAS) program in India.
Through his work, he aims to feed nutritionally rich and safe food globally through best collective efforts for enhancing farming systems’ productivity with efficient resource use and the adoption of conservation agriculture-based preferred technologies at grassroot level.
The International Maize and Wheat Improvement Center (CIMMYT) and Join Hope have cemented their partnership at a research cooperation agreement signing ceremony on November 14.
Join Hope produce seed products including maize, wheat, cotton, and soybean, as well as fertilizers, agricultural films and other products. The company will be providing some funding for five years and will receive access to CIMMYT’s international wheat nurseries and some maize inbred lines, in addition to training and other services. The funding will strengthen CIMMYT’s research efforts in China and create opportunities for training in Pakistan.
“CIMMYT and China have developed a win-win partnership that was established back in 1974,” said CIMMYT Director General Bram Govaerts. “Over 48 years, we have collaborated and advanced research for agricultural development in the areas of breeding, genomic research, and sustainable farming systems.”
Through this partnership, as much as 10.7 million tons of grain has been added to China’s wheat output. More than 26,000 CIMMYT wheat accessions were introduced and stored in China, and more than 300 wheat cultivars derived from CIMMYT germplasm have been released in China and are currently grown on nearly 10 percent of the Chinese wheat production area.
“The cooperation agreement that we sign today is another step in the right direction,” continued Govaerts. “It will bring us closer to the Chinese farmer and grain consumers who we all aim to serve.”
