Farewell to the “Father of the Green Revolution in India”, M.S. Swaminathan

CIMMYT joins with members of the international development community to mourn the passing of renowned wheat geneticist and “Father of the Green Revolution in India,” Monkombu Sambasivan Swaminathan who died on September 27 at the age of 98.

Swaminathan devoted his life to sustainably feeding the world. His vision reshaped India almost overnight to a breadbasket for South Asia, through adoption of innovative high-yield wheat varieties and efficient farming techniques for Indian farmers. TIME magazine acclaimed him as one of the twenty most influential Asians of the 20th Century, making him one of three from India to be named alongside Mahatma Gandhi and Rabindranath Tagore.

Swaminathan began his career in the world of academia. After earning his Ph.D. in plant genetics from Cambridge University in 1952, he moved to the United States to continue his research as a professor; however, his home country India eventually called him back home. With the crisis of a rapidly increasing population and low food production, Swaminathan returned to become a scientist at the Indian Agricultural Research Institute (IARI), where he later served as Director from 1961 to 1972.

It was during this time that he began his collaboration scientist Norman Borlaug, future Nobel Prize laureate and soon to be leader of CIMMYT wheat research. Swaminathan saw the value of the Mexican semi-dwarf wheat varieties, which were developed by Borlaug, for wheat production in India and requested that Borlaug send him a range of breeding materials containing the Norin dwarfing genes. The seeds arrived in 1963 along with Borlaug and the pair travelled the wheat-belt of India. Swaminathan arranged multi-location trials for the varieties and established an inter-disciplinary team to adapt the new varieties for Indian conditions.

The next step was convincing local farmers to grow the varieties. By 1966, Swaminathan had established 2,000 model farms where farmers could see for themselves the benefits of the new wheats. Swaminathan’s final act in kickstarting the Green Revolution in India was to successfully lobby the Indian government to import 18,000 tons of the Mexican seed.

Just 4 years later India’s wheat harvest had doubled to 20 million tons, ending the nation’s dependence on wheat imports and saving millions from starvation. Swaminathan continued to work with the Indian government to maintain food security and long-term self-sufficiency across the country and the impact of his work earned him the first World Food Prize in 1987.

Swaminathan held a number of leadership roles in world agricultural and conservation organizations over his lifetime, including the FAO council, the International Union for the Conservation of Nature and Natural Resources, the World Wide Fund for Nature (India), and the National Academy of Agricultural Sciences. He also served as Director General of the Indian Council of Agricultural Research (ICAR), and Secretary to the Government of India at the Department of Agricultural Research and Education from 1972-79, as well as Director General of the International Rice Research Institute in the Philippines from 1982-88.

A humanitarian at heart

Not just a scientist, Swaminathan was an advocate and humanitarian. Shortly after winning the World Food Prize, he used the award funds to establish a research center, the M.S. Swaminathan Research Foundation (MSSRF), in Chennai, India. The MSSRF allowed him to work on his other passion, sustainable development, where he coordinated research and action on conservation of endangered species, protection of coastal ecosystems, precision farming, ecotechnology, community education and technical training, and programs for rural internet access.

He has received 84 honorary doctorate degrees from universities around the world and multiple awards including the Padma Shri (1967), Padma Bhushan (1972) and Padma Vibushan (1989) – the fourth, third and second highest civilian awards in India. He has also won numerous international awards including the 1994 UNEP Sasakawa Environment Prize, the UNESCO Gandhi Gold Medal in 1999 and the Franklin D. Roosevelt Four Freedoms Award in 2000.

“He was a real gentleman with a sharp memory,” recalls CIMMYT distinguished scientist Ravi Singh. “I always admired his capacity and his ability to link complicated topics into a nice synthesis.”

He was an inspiration to thousands and will be greatly missed for his scientific brilliance, his pioneering advocacy and humanitarianism, and his life mission to reduce world hunger through improved technology for citizens from all levels of society.

The CIMMYT family extends its deepest condolences to the Swaminathan family.

Harnessing new high-resolution satellite imagery to plant breeding

In plant breeding, efforts to increase the rate of genetic gains and enhance crop resilience to the effects of climate change are often limited by the inaccessibility and costs of phenotyping methods. The recent rapid development of sensors, image-processing technology and data analysis has provided new opportunities for multiple scales phenotyping methods and systems. Among these, satellite imagery may represent one of the best ways to remotely monitor trials and nurseries planted in multiple locations, while standardizing protocols and reducing costs.

This is because relevant data collected as part of crop phenotyping can be generated from satellite images. For instance, the sensors onboard the SkySat satellite constellation of Planet Labs have four spectral bands—blue, green, red, and infrared—which can be used to calculate the normalized difference vegetation index (NDVI), which is a measure of vegetation and its greenness, and various canopy traits like ground cover, leaf area index and chlorosis. It can also be used to monitor plot establishment and phenological parameters.

The use of satellite-based phenotyping in breeding trials has typically been restricted by low resolution, high cost and long intervals between fly-overs. However, the advent of a new generation of high-resolution satellites—such as the SkySat constellation—now offers multispectral images at a 0.5m resolution with close to daily acquisition attempts on any place on Earth. This could be a game changer in terms of the scale at which yield trials can be conducted, enabling more precise variety placement and thereby increasing genetic diversity across farmer’s fields and reducing the probability of disease epidemics. It could also revolutionize the capacity for research in realistic field conditions, since traits can be measured throughout the cycle in a highly standardized way, over multiple sites at low cost. For example, an image which covers 25 km2 can monitor an entire research station at a cost of about US$300.

To test the suitability of this technology, a team of researchers from CIMMYT set out to evaluate the reliability of SkySat NDVI estimates for maize and wheat breeding plots of different sizes and spacing, as well as testing its capacity for detecting seasonal changes and genotypic differences.

Both their initial findings, recently published in Frontiers in Plant Science, and more recently acquired data, show that the SkySat satellites can be used to monitor plots commonly used in wheat and maize nurseries. While wheat yield plots usually are 1.2m wide, maize plots tend to consist of at least two rows, resulting in a width of 1.5m. Plot length ranges from 2-4m. The authors also discuss on other factors to be considered when extracting and interpreting satellite data from yield trials, such as plot spacing.

Through the successful collection of six satellite images in Central Mexico during the rainy season and parallel monitoring of a maize trial in Zimbabwe, the researchers demonstrate the flexibility of this tool. Beyond the improvement of spatial resolution, the researchers suggest that the next challenge will be the development and fine-tuning of operational procedures that ensure high quality, standardized data, allowing them to harness the benefits of the modern breeding triangle, which calls for the integration of phenomics, enviromics and genomics, to accelerate breeding gains.

CIMMYT announces 2030 Strategy

The world’s food systems are under threat by escalating armed conflicts, economic stagnation, the effects of the climate crisis and natural resource degradation. Against this backdrop, the next seven years are crucial in meeting the challenges of keeping the world’s growing population fed and secure.

Recognizing that business as usual will not be sufficient, CIMMYT has embarked on a journey to proactively face the new challenges of the 21st century. This novel approach to agrifood systems is the core of CIMMYT’s 2030 Strategy, which has the potential to shape the future of agriculture.

“We understand that the challenges facing food security are complex, varied and rapidly changing. For instance, the effects of COVID-19 and Ukraine-Russia conflict on food systems are still being felt today. With that in mind, we set out to develop a strategy that is both robust and nimble. The best way to create a sustainable and inclusive strategy was to engage directly with CIMMYT scientists and staff, the people on the front lines of this effort to deliver food and nutrition security to the world,” said CIMMYT Director General Bram Govaerts.

Looking back to move forward

The first step in crafting the 2030 Strategy was looking at where does CIMMYT want the world to be in 2100. In answering this question, CIMMYT crafted a long-term vision of how it wants to engage in a changing world and achieve the transformation to a food and nutrition secure world within planetary boundaries. CIMMYT has integrated the use of foresight and specifically a set of 2030 Food and Agriculture scenarios to explore potential changes in intervention areas over the strategic period and help prepare engagements in different contexts across the globe. These scenarios are a decision-making tool that has underpinned the development of the strategy to ensure that it is context-driven and focused on the most pressing challenges facing the agrifood systems in which CIMMYT operates.

From the future CIMMYT looks back at its history and examines how its core business has evolved over the years to proactively meet ever-changing needs across the world.

At each stage of CIMMYT’s evolution, it has taken its strengths and the skills it has built and added to its experience, and expanded on what it delivers while maintaining the core strengths.

In CIMMYT’s earliest days, the mission was developing and improving germplasm and agronomic practices, then CIMMYT began working more closely with farmers (1980s), broadened emphasis in genetic improvements (2000), embarked on sustainable multidisciplinary projects (2010s), and most recently, advancing technologies in participatory innovation systems (2015-2022). All leading to the mission codified in the 2030 Strategy: accelerating food systems transformation by using the power of collective action.

Now, in 2023, CIMMYT’s progress is being shaped by the CGIAR mission statement: “To deliver science and innovation that advance the transformation of food, land, and water systems in a climate crisis.”

Building the Strategy

To define the 2030 Strategy, CIMMYT responded to the following core questions:

  • What does success look like?
  • Where can CIMMYT deliver the most value?
  • How can CIMMYT deliver value for communities?

“As an organization, we have concentrated on strategies that foster collaboration and adapt them for a non-profit international organization whose vision is not to grow as an institution but to deliver greater value for the communities they serve, to innovate for the end users of their products and to ensure a better future for our global community,” said Govaerts.

The tools used to develop the elements of this strategic plan leveraged the framework provided in the CGIAR Research and Innovation Strategy to guide the process. Staff from across the Center engaged in a consultative process to develop the objectives for following strategic components: Excellence in Science and Innovation, Excellence in Operations, Talent Management, Resource Mobilization, Partnership, and Influence.

Developing the Excellence in Science and Innovation component serves as an example of this collaborative, bottom-up approach. Planning was led by the Emerging Thought Leaders Group, made up of 24 early and mid-career scientists across the breadth of CIMMYT’s global and program portfolio. The group worked collaboratively with CIMMYT researchers and staff to first delineate the challenges facing agri-food systems and then workshopped solutions which now serve as the foundation of the 2030 Strategy.

“Each component complements the others,” said Govaerts. “This is our answer to the core questions. Only by working collectively can we initiate sustainable solutions that reach everyone.”

Together, the components create a network to support CIMMYT’s three pillars: Discovery (research and innovation), SystemDev (working collaboratively to innovate foundational systems), and Inc. (incubating startups and new ways of doing business in the agri-food system space).

CIMMYT is leading the way in shaping a sustainable and prosperous agricultural landscape

The goal to facilitate food security where sustainable agriculture is part of the solution to the climate crisis and agriculture provides an avenue to build household resilience and enables communities to pull themselves out of poverty requires the strategic use of resources. CIMMYT’s 2030 Strategy, built from the bottom up on a foundation over 50 years’ experience and the expertise of scientists, staff, and farmers maximizes resources, enhances dynamic partnerships, and both retains and recruits a world-class staff in a world of growing challenges to food security.

Country moving forward from wheat importer to self-sufficiency

Wheat is critical to millions of households in Pakistan as it serves a dual role as a foundational part of nutritional security and as an important part of the country’s economy. Pakistan’s goal to achieve self-sufficiency in wheat production is more attainable with the release of 31 wheat varieties since 2021.

These new seeds will help the country’s 9 million hectares of cultivated wheat fields become more productive, climate resilient, and disease resistant—a welcome development in a region where climate change scenarios threaten sustained wheat production.

The varieties, a selection of 30 bread wheat and 1 durum wheat, 26 of which developed from wheat germplasm provided by the International Maize and Wheat Improvement Center (CIMMYT) were selected after rigorous testing of international nurseries and field trials by partners across Pakistan. During this period, three bread wheat varieties were also developed from local breeding programs and two varieties (one each of durum and bread wheat) were also developed from the germplasm provided by the ICARDA. These efforts are moving Pakistan closer to its goal of improving food and nutrition security through wheat production, as outlined in the Pakistan Vision 2025 and Vision for Agriculture 2030.

Over multiple years and locations, the new varieties have exhibited a yield potential of 5-20% higher than current popular varieties for their respective regions and also feature excellent grain quality and attainable yields of over seven tons per hectare.

The new crop of varieties exhibit impressive resistance to leaf and yellow rusts, compatibility with wheat-rice and wheat-cotton farming systems, and resilience to stressors such as drought and heat.

Battling malnutrition

Malnutrition is rampant in Pakistan and the release of biofortified wheat varieties with higher zinc content will help mitigate its deleterious effects, especially among children and women. Akbar-2019, a biofortified variety released in 2019, is now cultivated on nearly 3.25 million hectares. Farmers like Akbar-2019 because of its 8-10% higher yields, rust resistance, and consumers report its good chapati (an unleavened flatbread) quality.

“It is gratifying seeing these new varieties resulting from collaborative projects between Pakistani wheat breeding programs and CIMMYT along with funding support from various donors (USAID, Bill & Melinda Gates Foundation, HarvestPlus, and FCDO) and the government of Pakistan,” said Ravi Singh, wheat expert and senior advisor.

Closing the yield gap between research fields and smallholder fields

Releasing a new variety is only the first step in changing the course of Pakistan’s wheat crop. The next step is delivering these new, quality seeds to markets quickly so farmers can realize the benefits as soon as possible.

Increasing evidence suggests the public sector cannot disseminate enough seeds alone; new policies must create an attractive environment for private sector partners and entrepreneurs.

“Pakistan has developed a fast-track seed multiplication program which engages both public and private sectors so the new varieties can be provided to seed companies for multiplication and provided to farmers in the shortest time,” said Javed Ahmad, Wheat Research Institute chief scientist.

Strengthening and diversifying seed production of newly released varieties can be done by decentralizing seed marketing and distribution systems and engaging both public and private sector actors. Marketing and training efforts need to be improved for women, who are mostly responsible for household level seed production and seed care.

A concerted effort to disseminate the improved seed is required, along with implementing conservation agriculture based sustainable intensification, to help Pakistan’s journey to self-sufficiency in wheat production.

CIMMYT Director General reaffirms commitment to Zambia

Honoring a legacy of innovative development in Zambia and looking forward to meeting the nation’s goals for food security, Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT), along with CGIAR Board Chair Lindiwe Sibanda, visited facilities and met with southern Africa collaborators of the Southern Africa AID-I Rapid Delivery Hub on June 2 and 3, 2023.

“CIMMYT’s work in Zambia and the region is geared to help national governments build resilience to climate change, diversify maize-based farming systems and improve productivity and production to address reduce hunger and poverty,” said Govaerts.
Southern Africa AID-I Rapid Delivery Hub aims to provide critical support to over 3 million farming households in Malawi, Tanzania and Zambia via targeted interventions for demand driven seed scaling, improved soil health and fertilizer use efficiency, and rapid delivery of critical agricultural advisory services deep into rural communities.

CIMMYT research and innovation supports Zambia’s medium-term goal of “Socio-Economic Transformation for Improved Livelihoods” and its 2030 Vision of becoming “A Prosperous Middle-Income Nation by 2030.”

Govaerts and Sibanda toured Afriseed’s factory in Lusaka and its wheat field trials in Ngwerere. They also attended a field demonstration of Purdue Improved Crop Storage bags in the nearby district of Chongwe organized by the Catholic Relief Services, a local partner promoting low-cost post-harvest technologies for small-scale farmers in Zambia.
The delegation visited private partner Zamseed, a company commercializing and releasing CIMMYT-bred, Fall Armyworm tolerant maize seeds.

Southern Africa AID-I Rapid Delivery Hub has enabled the release of nearly 10,000 metric tons of certified maize and legume seed, which have been harvested by Zambian seed companies and community-based seed organizations, directly benefiting a million semi-subsistence farmers.

Govaerts also hailed Zambia’s commitment to creating a transparent seed system. “Thanks to this conducive policy environment, Zambia is a major hub in sub-Saharan Africa for hybrid maize seed production and export in Africa.”

Besides Southern Africa AID-I Rapid Delivery Hub, CIMMYT and the Zambia Agricultural Research Institute have been collaborating for over two decades along with public and private partners in Zambia through different investments designed to create sustainable interventions that strengthen food systems and directly reach small-scale farmers.

Wheat output in Africa and South Asia will suffer severely from climate change by 2050, modelling study shows

Leading crop simulation models used by a global team of agricultural scientists to simulate wheat production up to 2050 showed large wheat yield reductions due to climate change for Africa and South Asia, where food security is already a problem.

The model predicted average declines in wheat yields of 15% in African countries and 16% in South Asian countries by mid-century, as described in the 2021 paper “Climate impact and adaptation to heat and drought stress of regional and global wheat production,” published in the science journal Environmental Research Letters. Climate change will lower global wheat production by 1.9% by mid-century, with the most negative impacts occurring in Africa and South Asia, according to the research.

“Studies have already shown that wheat yields fell by 5.5% during 1980-2010, due to rising global temperatures,” said Diego N.L. Pequeno, wheat crop modeler at the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the paper. “We chose several models to simulate climate change impacts and also simulated wheat varieties that featured increased heat tolerance, early vigor against late season drought, and late flowering to ensure normal biomass accumulation. Finally, we simulated use of additional nitrogen fertilizer to maximize the expression of these adaptive traits.”

The wheat simulation models employed — CROPSIM-CERES, CROPSIM, and Nwheat within the Decision Support System for Agrotechnology Transfer, DSSAT v.4.6 — have been widely used to study diverse cropping systems around the world, according to Pequeno.

“The DSSAT models simulated the elevated CO2 stimulus on wheat growth, when N is not limiting,” he said. “Our study is the first to include combined genetic traits for early vigor, heat tolerance, and late flowering in the wheat simulation.”

Several factors, including temperature, water deficit, and water access, have been identified as major causes in recent wheat yield variability worldwide. The DSSAT wheat models simulate the impact of temperature, including heat stress, water balance, drought stress, or nitrogen leaching from heavy rainfall.

“Generally, small and low-volume wheat producers suffered large negative impacts due to future climate changes, indicating that less developed countries may be the most affected,” Pequeno added.

Climate change at high latitudes (France, Germany, and northern China, all large wheat-producing countries/region) positively impacted wheat grain yield, as warming temperatures benefit wheat growth through an extended early spring growing season. But warmer temperatures and insufficient rainfall by mid-century, as projected at the same latitude in Russia and the northwestern United States, will reduce rainfed wheat yields — a finding that contradicts outcomes of some previous studies.

At lower latitudes that are close to the tropics, already warm, and experiencing insufficient rainfall for food crops and therefore depending on irrigation (North India, Pakistan, Bangladesh), rising heat will damage wheat crops and seriously reduce yields. China, the largest wheat producer in the world, is projected to have mixed impacts from climate change but, at a nation-wide scale, the study showed a 1.2% increase in wheat yields.

“Our results showed that the adaptive traits could help alleviate climate change impacts on wheat, but responses would vary widely, depending on the growing environment and management practices used,” according to Pequeno. This implies that wheat breeding for traits associated with climate resilience is a promising climate change adaptation option, but its effect will vary among regions. Its positive impact could be limited by agronomical aspects, particularly under rainfed and low soil N conditions, where water and nitrogen stress limit the benefits from improved cultivars.

Extreme weather events could also become more frequent. Those were possibly underestimated in this study, as projections of heat damage effects considered only changes in daily absolute temperatures but not possible changes in the frequency of occurrence. Another limitation is that most crop models lack functions for simulating excess water (e.g., flooding), an important cause of global wheat yield variability.

This study was supported by the CGIAR Research Program on Wheat agri-food systems (CRP WHEAT; 2012-2021), the CGIAR Platform for Big Data in Agriculture, the International Wheat Yield Partnership (IWYP115 Project), the Bill & Melinda Gates Foundation, the World Bank, the Mexican government through the Sustainable Modernization of Traditional Agriculture (MasAgro) project, and the International Treaty of Plant Genetic Resources for Food and Agriculture and its Benefit-sharing Fund for co-funding the project, with financial support from the European Union.

Research awards to tackle challenge of fortifying wheat against heat and drought

As part of its crucial mission to accelerate wheat adaptation to rapidly changing climate conditions due to global warming, the Heat and Drought Wheat Improvement Consortium (HeDWIC) with the support of the Foundation for Food & Agriculture Research (FFAR) has granted 10 awards since 2021, crowdsourcing innovative research from around the world.

Like other crops, wheat – which makes up 20 percent of the human diet – 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.

“While some areas are becoming more conducive to wheat growing, crop yields are suffering in other regions around the world traditionally known as bread baskets,” said wheat physiologist Matthew Reynolds, who leads HeDWIC at the International Maize and Wheat Improvement Center (CIMMYT).

“Wheat is one of our fundamental crops, and we must spare no effort in protecting it from current and future challenges,” said Saharah Moon Chapotin, FFAR executive director. “Global 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.”

The 10 recipient projects are under the umbrella of the HeDWIC project Harnessing Translational Research Across a Global Wheat Improvement Network for Climate Resilience, funded by FFAR. The first five awardee projects were identified in 2021, and an additional five projects were awarded in 2022.

To boost new ideas in “climate-proofing” 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 CIMMYT’s experimental research station on the outskirts of Ciudad Obregon, a city in Mexico’s Sonoran Desert, during CIMMYT’s annual Visitors’ Week.

Projects awarded in 2022

  • Exploring the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat (FluoSense4Wheat)

“The 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.” – Onno Muller, Forschungszentrum Jülich, Institute of Bio- and Geosciences, Germany

  • Physiological basis of amelioration of heat stress through nitrogen management in wheat

“Heat 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.” – Renu Pandey, Division of Plant Physiology, Indian Agricultural Research Institute

  • Can reproductive development be protected from heat stress by the trehalose 6-phosphate pathway?

“The 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.” – Matthew Paul, Rothamsted Research, UK

  • Investigating tolerance of heat resilient wheat germplasm to drought

“Over 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.” – William Salter, University of Sydney, Australia

  • Novel wheat architecture alleles to optimize biomass under drought

“Wheat 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.” – Steve Thomas, Rothamsted Research, UK

Additional comments from 2021 awardees

“This opportunity has enabled the collection of significant amounts of data that will contribute to the advancement of knowledge in crop physiology and root biology. It has also provided early career researchers with opportunities to gain hands-on experience, develop important skills, and grow their networks. Additionally, this initiative has stimulated further ideas and collaborations among researchers, fostering a culture of innovation and cooperation that is essential for progress.” – Hannah Schneider, Wageningen University & Research, Netherlands

“The project is a unique opportunity for research groups from around the world to coordinate efforts on identifying ways to improve heat tolerance of wheat.” – Owen Atkin, Australian National University, Australia

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.
