India transforms wheat for the world

Written by Mike Listman on . Posted in Features.

India can applaud a hallmark in national food production: in 2023, the harvest of wheat—India’s second most important food crop—will surpass 110 million tons for the first time.

This maintains India as the world’s number-two wheat producer after China, as has been the case since the early 2000s. It also extends the wheat productivity jumpstart that begun in the Green Revolution—the modernization of India’s agriculture during the 1960s-70s that allowed the country to put behind it the recurrent grain shortages and extreme hunger of preceding decades.

“Newer and superior wheat varieties in India continually provide higher yields and genetic resistance to the rusts and other deadly diseases,” said Distinguished Scientist Emeritus at CIMMYT, Ravi Singh. “More than 90 percent of spring bread wheat varieties released in South Asia in the last three decades carry CIMMYT breeding contributions for those or other valued traits, selected directly from the Center’s international yield trials and nurseries or developed locally using CIMMYT parents.”

Wheat grain yield in Indian farmers’ fields rose yearly by more than 1.8 percent—some 54 kilograms per hectare—in the last decade, a remarkable achievement and significantly above the global average of 1.3 percent. New and better wheat varieties also reach farmers much sooner, due to better policies and strategies that speed seed multiplication, along with greater involvement of private seed producers.

“The emergence of Ug99 stem rust disease from eastern Africa in the early 2000s and its ability to overcome the genetic resistance of older varieties drove major global and national initiatives to quickly spread the seed of newer, resistant wheat and to encourage farmers to grow it,” Singh explained. “This both protected their crops and delivered breeding gains for yield and climate resilience.”

CIMMYT has recently adopted an accelerated breeding approach that has reduced the breeding cycle to three years and is expected to fast-track genetic gains in breeding populations and hasten delivery of improvements to farmers. The scheme builds on strong field selection and testing in Mexico, integrates genomic selection, and features expanded yield assays with partner institutions. To stimulate adoption of newer varieties, the Indian Institute of Wheat and Barley Research (IIWBR, of the Indian Council of Agricultural Research, ICAR) operates a seed portal that offers farmers advanced booking for seed of recently released and other wheat varieties.

Private providers constitute another key seed source. In particular, small-scale seed producers linked to the IIWBR/ICAR network have found a profitable business in multiplying and marketing new wheat seed, thus supporting the replacement of older, less productive or disease susceptible varieties.

Farm innovations for changing climates and resource scarcities

Following findings from longstanding CIMMYT and national studies, more Indian wheat farmers are sowing their crops weeks earlier so that the plants mature before the extreme high temperatures that precede the monsoon season, thus ensuring better yields.

New varieties DBW187, DBW303, DBW327, DBW332 and WH1270 can be planted as early as the last half of October, in the northwestern plain zone. Recent research by Indian and CIMMYT scientists has identified well-adapted wheat lines for use in breeding additional varieties for early sowing.

Resource-conserving practices promoted by CIMMYT and partners, such as planting wheat seed directly into the unplowed fields and residues from a preceding rice crop, shave off as much as two weeks of laborious plowing and planking.

“This ‘zero tillage’ and other forms of reduced tillage, as well as straw management systems, save the time, labor, irrigation water and fuel needed to plant wheat, which in traditional plowing and sowing requires many tractor passes,” said Arun Joshi, CIMMYT wheat breeder and regional representative for Asia and managing director of the Borlaug Institute for South Asia (BISA). “Also, letting rice residues decompose on the surface, rather than burning them, enriches the soil and reduces seasonal air pollution that harms human health in farm communities and cities such as New Delhi.”

Sustainable practices include precision levelling of farmland for more efficient irrigation and the precise use of nitrogen fertilizer to save money and the environment.

Science and policies ensure future wheat harvests and better nutrition

Joshi mentioned that increased use of combines has sped up wheat harvesting and cut post-harvest grain losses from untimely rains caused by climate change. “Added to this, policies such as guaranteed purchase prices for grain and subsidies for fertilizers have boosted productivity, and recent high market prices for wheat are convincing farmers to invest in their operations and adopt improved practices.”

To safeguard India’s wheat crops from the fearsome disease wheat blast, native to the Americas but which struck Bangladesh’s wheat fields in 2016, CIMMYT and partners from Bangladesh and Bolivia have quickly identified and cross-bred resistance genes into wheat and launched wheat disease monitoring and early warning systems in South Asia.

“More than a dozen wheat blast resistant varieties have been deployed in eastern India to block the disease’s entry and farmers in areas adjoining Bangladesh have temporarily stopped growing wheat,” said Pawan Singh, head of wheat pathology at CIMMYT.

Building on wheat’s use in many Indian foods, under the HarvestPlus program CIMMYT and Indian researchers applied cross-breeding and specialized selection to develop improved wheats featuring grain with enhanced levels of zinc, a micronutrient whose lack in Indian diets can stunt the growth of young children and make them more vulnerable to diarrhea and pneumonia.

“At least 10 such ‘biofortified’ wheat varieties have been released and are grown on over 2 million hectares in India,” said Velu Govindan, CIMMYT breeder who leads the Center’s wheat biofortification research. “It is now standard practice to label all new varieties for biofortified traits to raise awareness and adoption, and CIMMYT has included high grain zinc content among its primary breeding objectives, so we expect that nearly all wheat lines distributed by CIMMYT in the next 5-8 years will have this trait.”

A rigorous study published in 2018 showed that, when vulnerable young children in India ate foods prepared with such zinc-biofortified wheat, they experienced significantly fewer days of pneumonia and vomiting than would normally be the case.

Celebrating joint achievements and committing for continued success

The April-June 2018 edition of the “ICAR Reporter” newsletter called the five-decade ICAR-CIMMYT partnership in agricultural research “…one of the longest and most productive in the world…” and mentioned mutually beneficial research in the development and delivery of stress resilient and nutritionally enriched wheat, impact-oriented sustainable and climate-smart farming practices, socioeconomic analyses, and policy recommendations.

Speaking during an August 2022 visit to India by CIMMYT Director General Bram Govaerts,  Himanshu Pathak, secretary of the Department of Agricultural Research and Education (DARE) of India’s Ministry of Agriculture and Farmers Welfare and Director General of ICAR, “reaffirmed the commitment to closely work with CIMMYT and BISA to address the current challenges in the field of agricultural research, education and extension in the country.”

“The ICAR-CIMMYT collaboration is revolutionizing wheat research and technology deployment for global food security,” said Gyanendra Singh, director, ICAR-IIWBR. “This in turn advances global peace and prosperity.”

According to Govaerts, CIMMYT has concentrated on strategies that foster collaboration to deliver greater value for the communities both ICAR and the Center serve. “The way forward to the next milestone — say, harvesting 125 million tons of wheat from the same or less land area — is through our jointly developing and making available new, cost effective, sustainable technologies for smallholder farmers,” he said.

Wheat research and development results to date, challenges, and future initiatives occupied the table at the 28th All India Wheat & Barley Research Workers’ Meeting, which took place in Udaipur, state of Rajasthan, August 28-30, 2023, and which ICAR and CIMMYT wheat scientists attended.

Generous funding from various agencies, including the following, have supported the work described: The Australian Centre for International Agricultural Research (ACIAR), the Bill & Melinda Gates Foundation, the Federal Ministry for Economic Cooperation and Development of Germany (BMZ), the Foreign, Commonwealth & Development Office of UK’s Government (FCDO), the Foundation for Food & Agricultural Research (FFAR), HarvestPlus, ICAR, the United States Agency for International Development (USAID), funders of the One CGIAR Accelerated Breeding Initiative (ABI), and the Plant Health Initiative (PHI).

Former CIMMYT wheat scientist, Mohan Kohli, receives Paraguay’s National Order of Merit award

Written by Mike Listman on . Posted in News.

Paraguay’s Minister of Foreign Affairs, Ambassador Julio César Arriola, recently bestowed on Man Mohan Kohli, retired wheat geneticist of CIMMYT the “Comendador” award of the country’s National Order of Merit, highlighting the scientist’s “…exceptional contribution to Paraguayan agriculture and economy.”

A dedicated field specialist, on 2 August 2023 retired CIMMYT wheat geneticist Man Mohan Kohli was recognized as “Comendador” of the Paraguay’s National Order of Merit. In his acceptance speech, Kohli cited the benefits of public-private partnerships to profit farmers and catalyze food grain value chains. (Photo: CIMMYT)

A native of India, where he completed schooling including a Ph.D. in wheat genetics, Kohli worked at CIMMYT during 1971-2004 on topics including spring x winter wheat crosses, resistance in wheat to the rust and other diseases, and the improvement and promotion of triticale, a wheat x rye hybrid.

In 1978 he was assigned to a CIMMYT regional program involving wheat breeding, development and training in collaboration with countries of the Southern Cone of South America, which included facilitating the regional testing and exchange of wheat breeding lines and selection data.

As of 2004, Kohli has been an active part-time consultant with Paraguay’s national wheat program and the Bioceres Group in Argentina.

“Funding ended for CIMMYT wheat research in Paraguay in 1993,” Kohli said. “In 2003 we started direct cooperation again through a joint venture including the Ministry of Agriculture and Livestock, the Paraguayan Chamber of Cereals and Oilseeds Exporters, and CIMMYT.”

“Back in 2003, Paraguay was producing about 320,000 tons of wheat each year and importing over 200,000 tons. Now, yearly output is around 1 million tons and the country exports almost a third of that.”

Kohli said the joint initiative had promoted higher-yielding wheat varieties and farming methods, lowered the costs of agrochemicals, and helped form associations involving farmers and millers—the complete cycle from sowing to marketing for wheat.

Paraguayans eat an average of over 85 kilograms of wheat each year as pasta, bread and other bakery products.

Kohli’s career has led him to work with science luminaries such as M.S. Swaminathan, Glenn Anderson, Joe Rupert, Cal Qualset, Warren Kronstad, Frank Zillinsky, and Sanjaya Rajaram, among others.

“I met CIMMYT scientist and eventual Nobel Peace laureate, Dr. Norman E. Borlaug, in 1967,” Kohli said. “We continued to meet every year on his visits to India and, when I was about to finish my Ph.D. in 1970, he invited me to join the team at CIMMYT.”

“It has been a privilege and honor to have worked alongside many dedicated colleagues at CIMMYT and national programs who have contributed significantly to building research capacities and global food security over the last 50 years. This award is dedicated to all of them and the farmers who have been the primary source of inspiration for our work”.

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

Written by Julian Bañuelos-Uribe on . Posted in News.

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

Written by Julian Bañuelos-Uribe on . Posted in Publications.

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

Written by Julian Bañuelos-Uribe on . Posted in Features.

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

Written by mcallejas on . Posted in Features.

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

Written by Julian Bañuelos-Uribe on . Posted in News.

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

Written by Julian Bañuelos-Uribe on . Posted in Publications.

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

“It is important to understand how high temperature limits crop growth and yield and to identify genetic variation that can be used for breeding climate resilient crops. This project has already begun to develop new methods for rapidly screening growth and physiological processes in genetically diverse panels which we hope will be invaluable to researchers and breeders.” – Erik Murchie, University of Nottingham, UK

“This project will provide novel phenotyping screens and germplasm to breeders and lay the groundwork for genetic analysis and marker development.” – John Foulkes, University of Nottingham, UK

Wheat Disease Early Warning Advisory System (DEWAS)

Written by Sarah McLaughlin on . Posted in Uncategorized.

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

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

The Challenge

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

The Response

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

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

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