This week, the world’s eyes are upon global leaders gathered in Madrid for COP25 to negotiate collective action to slow the devastating impacts of climate change.
According to the UN, the world is heading for a 3.2 degrees Celsius global temperature rise over pre-industrial levels, leading to a host of destructive climate impacts including hotter and drier environments and more extreme weather events. Under these more extreme conditions, the world’s staple food crops are under threat.
A new video highlights the work of the Heat and Drought Wheat Improvement Network (HeDWIC), a global research and capacity building network under the Wheat Initiative, that harnesses the latest technologies in crop physiology, genetics and breeding to help create new climate-resilient wheat varieties. With the help of collaborators and supporters from around the world, HeDWIC takes wheat research from the theoretical to the practical by incorporating the best science into real-life breeding scenarios.
Wheat research leaders from the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agriculture in the Dry Areas (ICARDA) recently traveled to Turkey to discuss continued collaboration among Turkey’s Ministry of Agriculture and Forestry and the two institutions.

Two scientists working in the world’s leading public wheat breeding program at the International Maize and Wheat Improvement Center (CIMMYT) have been recognized with awards and fellowships this week at the annual meeting of the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America.
Hans-Joachim Braun, director of CIMMYT’s Global Wheat Program and the CGIAR Research Program on Wheat, has been honored with the American Society of Agronomy’s International Agronomy Award.
Alexey Morgunov, CIMMYT principal scientist and head of the Turkey-based International Winter Wheat Improvement Program (IWWIP) received the distinction of Fellow from the Crop Science Society of America. Braun was also distinguished with this fellowship.
Excellence in agronomy
The American Society of Agronomy’s International Agronomy Award recognizes outstanding contributions in research, teaching, extension, or administration made outside of the United States by a current agronomist. Braun received the distinction during an awards ceremony and lecture on November 12, 2019. The award committee made its selection based on criteria including degrees, professional positions, and contributions and service to the profession such as publications, patents, and efforts to develop or improve programs, practices, and products.
The award recognizes Braun’s achievements developing and promoting improved wheat varieties and cropping practices that have benefited hundreds of millions of farmers throughout Central Asia, South Asia and North Africa. Nearly half the world’s wheat lands overall — as well as 70 to 80% of all wheat varieties released in Central Asia, South Asia, West Asia, and North Africa — are derived from the research of CIMMYT and its partners.
“I am honored to be recognized by my fellow agronomists,” Braun said. “This award highlights the importance of international research collaboration, because the food security challenges we face do not stop at national borders.”
Braun began his 36-year CIMMYT career in Mexico in 1983. From 1985 to 2005, he led the International Winter Wheat Improvement Program in Turkey, implemented by CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA). As director of CIMMYT’s Global Wheat Program since 2004 and the CGIAR Research Program on Wheat since 2014, he is responsible for the technical direction and implementation of a program that develops and distributes wheat germplasm to more than 200 collaborators in more than 100 countries, grown on over half the spring wheat area in developing countries.
Braun and Morgunov were also chosen as Fellows, the highest recognition bestowed by the Crop Science Society of America. Members of the society nominate worthy colleagues based on their professional achievements and meritorious service. Fellows are a select group: only three out of every 1,000 of the society’s more than 4,000 active and emeritus members receive the honor.
Morgunov joined CIMMYT in 1991 as a spring wheat breeder, working with former Global Wheat Program Director and World Food Prize laureate Sanjaya Rajaram. In 1994, he moved to Turkey to work as winter wheat breeder, and then to Kazakhstan, where he worked to develop and promote new wheat varieties for the Central Asia and the Caucasus region. He has led the International Winter Wheat Improvement Program in Turkey since 2006. In this role, he has been responsible for the release of more than 80 varieties in the region. He also completed a national inventory for wheat landraces in Turkey.
“I am pleased to be recognized as [a Crop Science Society of America] Fellow,” Morgunov said. “I hope this award brings more attention to the importance of finding, saving and using the vast diversity of crop varieties in the world, for resilient crops and healthy food for all.”
Braun and Morgunov were formally recognized as Fellows on November 13.
The annual meeting of the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America convenes around 4,000 scientists, professionals, educators, and students to share knowledge and recognition of achievements in the field. This year’s meeting was held in San Antonio, Texas.
Thomas Payne, head of the Wheat Germplasm Bank at the International Maize and Wheat Improvement Center (CIMMYT), was awarded the Frank N. Meyer Medal for Plant Genetic Resources this morning at the annual meeting of the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America in San Antonio, Texas.
The Frank N. Meyer
Medal recognizes contributions to plant germplasm collection and use, as well
as dedication and service to humanity through the collection, evaluation or
conservation of earth’s genetic resources. The award was presented by Clare
Clarice Coyne, U.S. Department of Agriculture (USDA) research geneticist.
As an award recipient, Thomas Payne delivered a lecture that touched on the philosophy, history and culture surrounding plant genetic diversity and its collectors, and CIMMYT’s important role in conserving and sharing crop diversity.
Thomas Payne has focused his career on wheat improvement and conservation. In addition to leading CIMMYT’s Wellhausen-Anderson Wheat Genetic Resources Collection, one of the world’s largest collection of wheat and maize germplasm, he manages the CIMMYT International Wheat Improvement Network. He is the current Chair of the Article 15 Group of CGIAR Genebank Managers, and has served as Secretary to the CIMMYT Board of Trustees. His association with CIMMYT began immediately after obtaining a PhD at the University of Nebraska-Lincoln in 1988, and he has held positions for CIMMYT in Ethiopia, Mexico, Syria, Turkey and Zimbabwe.
“CIMMYT is the largest
distributor of maize and wheat germplasm worldwide, with materials emanating
from its research and breeding programs, as well as held in-trust in the
germplasm bank. The Meyer Medal is a
reflection of the impact CIMMYT makes in the international research community
— and in farmers’ fields throughout the
developing world,” he said.
Located at CIMMYT headquarters outside Mexico City, the CIMMYT Wheat Germplasm Bank contains nearly 150,000 collections of seed of wheat and related species from more than 100 countries. The collections preserve the diversity of unique native varieties and wild relatives of wheat and are held under long-term storage for the benefit of humanity, in accordance with the 2007 International Treaty on Plant Genetic Resources for Food and Agriculture. They are also studied and used as a source of diversity to breed for crucial traits such as heat and drought tolerance, resistance to crop diseases and pests, grain yield productivity and grain quality. Seed is freely shared on request to researchers, students, and academic and development institutions worldwide.
In his remarks, Thomas Payne also highlighted the story of Frank N. Meyer, for whom the award is named. Meyer, an agricultural explorer for the USDA in the 1900s, spent a decade traveling under harsh conditions through China to collect new plant species suitable for production on America’s expanding farmland. Among more than 2,500 plants that he introduced to the U.S. — including varieties of soybeans, oats, wild pears, and asparagus — the Meyer lemon was named in his honor. As Payne pointed out, Meyer worked during a historical period of great scientific discoveries, including those by his contemporaries Marie Curie and the Wright brothers.
Among those attending the ceremony were Thomas Payne’s sister, Susan Payne and CIMMYT colleagues Kevin Pixley, director of Genetic Resources; Denise Costich, head of the CIMMYT Maize Germplasm Bank; and Alexey Morgunov, head of the Turkey-based International Winter Wheat Improvement Program.
The head of CIMMYT’s Global Wheat Program Hans-Joachim Braun and CIMMYT scientist Alexey Morgunov are also receiving honors or awards this week at the annual meeting of the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America. The meeting convenes around 4,000 scientists, professionals, educators, and students to share knowledge and recognition of achievements in the field.
Highlights from the International Conference on Wheat Diversity and Human Healthwhich took place in Istanbul this week
Istanbul hosted a milestone conference this week convening experts
from the region and the globe to examine the link between wheat and human
health. Although wheat is the second
most popular food crop in the world, and a vital source of food and nutrition
for humans dating from the earliest days of agriculture, its reputation as a
health food has taken a hit in western popular culture in recent times.
Beyond the well-publicized benefits of consuming fiber from whole grain wheat products – including lower risk of coronary disease, diabetes, hypertension, obesity, Type 2 diabetes and colon cancer – scientists at the conference affirmed that wheat also contains compounds such as phenolics, flavonoids and carotenoids that:
have antioxidant and anti-inflammatory
reduce the risk of cancer and chronic diseases,
have a beneficial effect on the working memory,
can prevent neurological diseases such as Alzheimer’s
and Parkinson’s diseases,
can delay aging and
can prevent Vitamin A deficiency, among many
As remarkable as these benefits may be, wheat’s potential for improving
nutrition and health worldwide is even greater.
A number of wheat scientists from the International Maize and
Wheat Improvement Center (CIMMYT) presented evidence this week on new paths to further
increase and promote these traits in wheat.
CIMMYT senior scientist and wheat breeder Velu Govindan explained the progress and potential of breeding wheat with enhanced levels of grain zinc and iron as a cost-effective, sustainable solution to malnutrition. To date, more than 12 biofortified high zinc wheat varieties have been released, reaching close to 1 million households in target countries such as India and Pakistan. With the help of advanced genomics and speed breeding these varieties have the potential to become the standard for farmers, particularly in developing countries.
CIMMYT cropping systems agronomist ML Jat and
his co-authors demonstrated how farming techniques that improve soil health,
diversify production and enhance growing environments also increase the
nutritional quality of wheat – critical in the face of climate change
and higher CO2 concentrations that are projected to reduce the protein content
of rice and wheat by almost 8% by 2050.
Maria Itria Ibba, head of CIMMYT’s wheat
quality lab, shared an idea for helping improve global dietary fiber consumption
without radically changing eating habits: develop wheat with increased Arabinoxylans
(AX) — fiber components associated with reduced risk of diabetes, cholesterol,
cardiovascular disease and colon cancer located in the endosperm, the part of
the grain most often used in refined flour. Her preliminary findings suggest
that AX content is controlled by a relatively small number of genes, which
could be identified through molecular markers to effectively select for this
trait in the breeding process.
and promoting wheat diversity
Many presenters discussed ways to protect and promote wheat’s wide
diversity – from modern varieties, traditional landraces, ancient
grains, colored wheat and different species – all of which have huge
potential to enrich our diet.
Alex Morgunov, leader of the International
Winter Wheat Improvement Program and a conference organizer, described his
research in Afghanistan – where wheat is the life-sustaining food grain and no
meal is complete without a slice of wheat bread — to protect, improve, and
distribute its rare and numerous valuable wheat landraces. These ancient
varieties bring diversity, distinct baking characteristics and nutrition from
farmer fields to bakeries and to research stations, where they are employed in
breeding efforts to capture their unique desirable traits.
As Tom Payne, head of CIMMYT’s Wheat Germplasm Collections pointed
out, diversity is a crucial element to health, and genebanks such as
CIMMYT’s safeguard some of the largest and most widely used collections of crop
diversity in the world, critical to ending hunger and improving food and
Hans-Joachim Braun, director of CIMMYT’s global wheat program and co-chair of the event concluded the conference with remarks on future perspectives for wheat diversity and human health. He highlighted how 830 million people in the world – 11% of the population- still do not have enough to eat.
We live in an era that calls for large-scale social and environmental transformation. But society has taken only meager steps towards producing the unprecedented changes needed to achieve the Sustainable Development Goals. Those of us working on sustainable rural development understand that we face enormous challenges: from ending hunger and improving nutrition, to preserving vital ecosystems, tackling climate change, empowering women and ending poverty. But we are still caught up in a 20th century paradigm that sees the world as a logical, linear, technology-centric system. This approach has hardly worked in the past, and it will certainly fail in the future. We need to change the underlying system. We need a new way of working.
In a new paper, my colleagues and I at the International Maize and Wheat Improvement Center (CIMMYT) joined up with development experts to argue that agricultural development projects should stop focusing narrowly on changing farming conditions within a specific project context. For too long, the dominant approach has been to develop new agricultural practices and technologies, prove that they work, spread them to a few hundred farmers through controlled pilot projects, and then hope this is enough to convince governments, industry and millions of smallholder farmers to do things differently. This is akin to inventing the mobile phone but ignoring the need for electricity, cellular towers, network providers, or any of the other supporting elements that enable the use of the phone.
Instead, we argue that projects should be seen as vehicles for changing the underlying system that enables a technology to be successfully used by millions. This means acknowledging and engaging with the complex array of real-world elements that comprise these systems, such as infrastructure, market forces, politics, people and power relationships. We do not suggest that project implementers become experts in all of these things, but rather that they need to take them into account when developing scalable solutions, by studying the best scaling process for a particular context, and positioning their contributions within that wider context.
We need to change course and embrace new attitudes, new skills and new ways of collaborating if we want to produce sustainable systems change at scale. And one important part of this process involves reconsidering our approach to pilot programs.
Pilots never fail, pilots never scale Most pilots test whether an innovation works in a particular context. We liken this to building a greenhouse (a controlled environment) within a landscape (the real world). Pilot projects rely heavily on external resources and expertise, and are shielded from real world challenges like politics, regulations, market forces and finance. A crucial feature of pilot programs, and a key limitation, is that they don’t face the same pressure as actual programs to reach as many people as possible within a limited timeframe. That means they aren’t generating important lessons about the conditions needed to enable sustainable long-term adoption.
As a result, when the time comes to scale up a successful pilot project, we generally take one of two paths:
One path involves building a bigger greenhouse, which means expanding the controlled environment by doing more of the same with more money. But this approach is expensive, and unlikely to produce lasting change. The expanded project may indeed reach an impressive number of households, but this is no guarantee that they can and will continue to use a technology after the project ends. And this also doesn’t guarantee that adoption will spread.
The other conventional approach to scaling a pilot program is to simply remove the greenhouse and assume the innovation is so good that it will spontaneously scale itself. But as any gardener knows, a plant will not easily survive under real conditions once a greenhouse is removed. Likewise, farming communities are unlikely to continue using a new practice or technology if the surrounding system remains unchanged, since it is this very system that shaped their conventional way of farming.
Steps for achieving large scale – and lasting – change So what would a more effective approach to scale look like? We reviewed decades of experience and insights from a number of sectors, including agriculture, health, education, nutrition and urban planning. We identified the following strategies that can help rural development projects change their approach towards achieving impact:
Adopt a new mindset: Understand that overlapping economic social, technical and political systems shape peoples’ choices and behaviors. Recognize the stakeholder dynamics that determine the present situation. You need to understand the key players and rules of the game in order to engage with – and influence – them.
Design for scale from the start: Asking “Does the pilot project work?” is not enough. Start by asking “What happens beyond the pilot project, if it works?” Then work with strategic local partners that are willing and able to provide public/private funding and leadership to sustain the initiative once the pilot project ends. But keep in mind: This also means considering – and planning for – the unintended consequences that come along with big change initiatives.
Clarify your role: Scaling means intervening into a range of elements within a system, and implementing institutions need to recognize their strengths and limitations in doing so. If they find that they lack any key capabilities that could reduce a program’s effectiveness, they should collaborate strategically with others to better influence the many different parts of the system.
See pilots as building blocks: Rather than viewing pilot projects as distinct entities, see them as part of a bigger ecology of initiatives to achieve long-term change – for example, as elements of a sector or country development strategy, or of other emerging market-led initiatives.
The global agricultural development community is starting to come to grips with this new mindset and way of working. For instance, in Zimbabwe, CIMMYT and its partners are taking a fresh approach to encouraging small-scale farm mechanization. We are working on strengthening a wide range of functions that are needed to support a market for two-wheeled tractors. This includes creating demand for machinery among local smallholders through farmer-to-farmer demonstrations, field days and ICT solutions. The initiative also offers technical and business development training to service providers, mechanics, artisans and manufacturers, and develops the capacity of existing vocational training centers to provide ongoing machinery trainings. Private sector partners can access valuable insights and intelligence on the performance of different machines and their costs and benefits, and can also access profiles of potential customers, thus spurring demand. And aspiring service providers are connected to financial institutions that can provide loans for machinery purchase. This approach goes far beyond the typical technology-oriented pilot project, and shows the positive steps being taken to engage with, and ultimately disrupt, the different elements of the underlying system.
Pilot projects last 2-4 years, but scaling a successful pilot to national application can take 15 years. While we are seeing more initiatives move away from the technology transfer mindset focused only on products, end users and numbers, and towards a more systems-focused approach, critical mass is a long way off. Agricultural development organizations and their funders need to urgently change course and position themselves as key players in changing the system at scale, rather than pushing an innovation into the rigid, incumbent system. This requires linking up with the right partners on the ground, who can help make this broader approach to sustainable development into the “new normal.”

The Arab Women Leaders in Agriculture (Awla) fellowship program, the first of its kind, is designed to develop a cadre of aspiring Arab women researchers who are equipped with the knowledge and skills to make a positive difference in agriculture sustainability, in their countries in particular and the Arab region as a whole.
The cornerstones of the Awla fellowship are team-based capstone projects designed to put the skills, tools and knowledge gained during the program to practical use. Diverse teams of Fellows from varying nationalities and backgrounds are expected to produce a solution to a key challenge to women in agriculture, guided by the mentors, the Awla Steering Committee and selected stakeholders nominated by the Fellows. Fellows can choose from a variety of interdisciplinary topics as well as agriculture specific, as long as their topic of choice has a convincing value proposition. At the end of the fellowship program, the teams will present their capstone projects to relevant stakeholders to seek funding.
The first cohort of Awla Fellows — which includes researchers from Algeria, Egypt, Jordan, Lebanon, Morocco and Tunisia – met from June 30 to July 7 in Tunisia for an introductory workshop to kick off their 10-month fellowship. WHEAT is funding two students in this cohort.
The Awla Fellows are a highly successful group of agricultural engineers, professors, wheat breeders and working researchers in agronomy, biotechnology, soil sciences and other technical agricultural fields. The orientation workshop gave them the opportunity to get to know each other and their selected mentors, participate in trainings designed to build their leadership and project management capacity, and gain an understanding of the online coursework and assignments that will make up their training.
Leadership and guidance The workshop began with 6 days of training in positive psychology applications in leadership – a course that covered how to integrate concepts of resilience, creativity, finding meaning and purpose and more into both their interpersonal relationships and their organization management.
Next came a 3-day course to introduce the concepts of design thinking, a process for creative problem solving that encourages organizations to focus on the human needs of the people for whom they are creating. The Awla Fellows were encouraged to use these concepts to brainstorm notes for their team-based capstone projects, which involved addressing a key challenge faced by women in agriculture.
Mentorships An important objective of the Tunisia workshop was to clarify roles and set expectations for the Fellows’ relationships with their mentors. Awla mentors, nearly all of whom joined their mentees in Tunisia, ranged from laboratory directors, lead professors, and government officials. A 2-day mentoring orientation helped to establish the semi-structured mentoring relationship, whereby mentors will share their knowledge, skills and experience with the Fellows to help their development during the course of the Awla program and beyond.
Coursework The Awla Fellowship consists of a series of online courses ranging from project planning to science writing, research methods and data management. Awla administrators ensured each Fellow had full access to the customized set of courses. Senior Fellows who complete the Awla program will have access to more than 3000 other courses across domains.
Support Throughout the program, Awla administrators will continue to support the Fellows both virtually, by following up their on-line courses and capstone projects and seeking funding for conference participation, and in person during an upcoming workshop in Tunis from October 28 to November 4, 2019. A final closing workshop, hosted by the International Center for Biosaline Agriculture in the United Arab Emirates, will take place in February 2020. The Awla funders will then plan another cycle of the program, with a new cohort of Fellows.
The MENA region faces critical and urgent agricultural challenges related to improved food security and nutrition, a better research and development landscape, and economic and social benefits of a narrowed gender gap that will require both innovative and inclusive solutions. With this strong foundation, the Awla Fellows are poised to become leaders that can take on these challenges.
The world urgently needs a transformation of the global food system, leading to healthier diets for all and a drastic reduction in agriculture’s environmental impact. The major cereal grains must play a central role in this new revolution for the benefit of the world’s poorest people.
Pioneering research on our three most important cereal grains — maize, rice, and wheat — has contributed enormously to global food security over the last half century, chiefly by boosting the yields of these crops and by making them more resilient in the face of drought, flood, pests and diseases. But with more than 800 million people still living in chronic hunger and many more suffering from inadequate diets, much remains to be done. The challenges are complicated by climate change, rampant degradation of the ecosystems that sustain food production, rapid population growth and unequal access to resources that are vital for improved livelihoods.
In recent years, a consensus has emerged among agricultural researchers and development experts around the need to transform global food systems, so they can provide healthy diets while drastically reducing negative environmental impacts. Certainly, this is a central aim of CGIAR — the world’s largest global agricultural research network — which views enhanced nutrition and sustainability as essential for achieving the Sustainable Development Goals. CGIAR scientists and their many partners contribute by developing technological and social innovations for the world’s key crop production systems, with a sharp focus on reducing hunger and poverty in low- and middle-income countries of Africa, Asia and Latin America.
The importance of transforming food systems is also the message of the influential EAT-Lancet Commission report, launched in early 2019. Based on the views of 37 leading experts from diverse research disciplines, the report defines specific actions to achieve a “planetary health diet,” which enhances human nutrition and keeps the resource use of food systems within planetary boundaries. While including all food groups — grains, roots and tubers, pulses, vegetables, fruits, tree nuts, meat, fish, and dairy products — this diet reflects important shifts in their consumption. The major cereals, for example, would supply about one-third of the required calories but with increased emphasis on whole grains to curb the negative health effects of cheap and abundant supplies of refined cereals.
This proportion of calories corresponds roughly to the proportion of its funding that CGIAR currently invests in the major cereals. These crops are already vital in diets, cultures, and economies across the developing world, and the way they are produced, processed and consumed must be a central focus of global efforts to transform food systems. There are four main reasons for this imperative.
1. Scale and economic importance
The sheer extent of major cereal production and its enormous value, especially for the poor, account in large part for the critical importance of these crops in global food systems. According to 2017 figures, maize is grown on 197 million hectares and rice on more than 167 million hectares, mainly in Asia and Africa. Wheat covers 218 million hectares, an area larger than France, Germany, Italy, Spain and the UK combined. The total annual harvest of these crops amounts to about 2.5 billion tons of grain.
Worldwide production had an estimated annual value averaging more than $500 billion in 2014-2016. The prices of the major cereals are especially important for poor consumers. In recent years, the rising cost of bread in North Africa and tortillas in Mexico, as well as the rice price crisis in Southeast Asia, imposed great hardship on urban populations in particular, triggering major demonstrations and social unrest. To avoid such troubles by reducing dependence on cereal imports, many countries in Africa, Asia and Latin America have made staple crop self-sufficiency a central element of national agriculture policy.
2. Critical role in human diets
Cereals have a significant role to play in food system transformation because of their vital importance in human diets. In developing countries, maize, rice, and wheat together provide 48% of the total calories and 42% of the total protein. In every developing region except Latin America, cereals provide people with more protein than meat, fish, milk and eggs combined, making them an important protein source for over half the world’s population.
Yellow maize, a key source of livestock feed, also contributes indirectly to more protein-rich diets, as does animal fodder derived from cereal crop residues. As consumption of meat, fish and dairy products continues to expand in the developing world, demand for cereals for food and feed must rise, increasing the pressure to optimize cereal production.
In addition to supplying starch and protein, the cereals serve as a rich source of dietary fiber and nutrients. CGIAR research has documented the important contribution of wheat to healthy diets, linking the crop to reduced risk of type 2 diabetes, cardiovascular disease, and colorectal cancer. The nutritional value of brown rice compared to white rice is also well known. Moreover, the recent discovery of certain genetic traits in milled rice has created the opportunity to breed varieties that show a low glycemic index without compromising grain quality.
The major cereals have undergone further improvement in nutritional quality during recent years through a crop breeding approach called “biofortification,” which boosts the content of essential vitamins or micronutrients. Dietary deficiencies of this kind harm children’s physical and cognitive development, and leave them more vulnerable to disease. Sometimes called “hidden hunger,” this condition is believed to cause about one-third of the 3.1 million annual child deaths attributed to malnutrition. Diverse diets are the preferred remedy, but the world’s poorest consumers often cannot afford more nutritious foods. The problem is especially acute for women and adolescent girls, who have unequal access to food, healthcare and resources.
It will take many years of focused effort before diverse diets become a reality in the lives of the people who need them most. Diversified farming systems such as rice-fish rotations that improve nutritional value, livelihoods and resilience are a step in that direction. In the meantime, “biofortified” cereal and other crop varieties developed by CGIAR help address hidden hunger by providing higher levels of zinc, iron and provitamin A carotenoids as well as better protein quality. Farmers in many developing countries are already growing these varieties.
A 2018 study in India found that young children who ate zinc-biofortified wheat in flatbread or porridge became ill less frequently. Other studies have shown that consumption of provitamin A maize improves the body’s total stores of this vitamin as effectively as vitamin supplementation. Biofortified crop varieties are not a substitute for food fortification (adding micronutrients and vitamins during industrial food processing). But these varieties can offer an immediate solution to hidden hunger for the many subsistence farmers and other rural consumers who depend on locally produced foods and lack access to fortified products.
4. Wide scope for more sustainable production
Cereal crops show much potential not only for enhancing human heath but that of the environment as well. Compared to other crops, the production of cereals has relatively low environmental impact, as noted in the EAT-Lancet report. Still, it is both necessary and feasible to further enhance the sustainability of cereal cropping systems. Many new practices have a proven ability to conserve water as well as soil and land, and to use purchased inputs (pesticides and fertilizers) far more efficiently. With innovations already available, the amount of water used in current rice cultivation techniques, for example, can be significantly reduced from its present high level.
Irrigation scheduling, laser land leveling, drip irrigation, conservation tillage, precision nitrogen fertilization, and cereal varieties tolerant to drought, flooding and heat are among the most promising options. In northwest India, scientists recently determined that optimal practices can reduce water use by 40%, while maintaining yields in rice-wheat rotations. There and in many other places, the adoption of new practices to improve cereal production in the wet season not only leads to more efficient resource use but also creates opportunities to diversify crop production in the dry season. Improvements to increase cereal crop yields also reduces their environmental footprint; using less land, enhancing carbon sequestration and biodiversity and, for rice, reducing methane emissions per kilo of rice produced. Given the enormous extent of cereals cultivation, any improvement in resource use efficiency will have major impact, while also freeing up vast amounts of land for other crops or natural vegetation.
A major challenge now is to improve access to the knowledge and inputs that will enable millions of farmers to adopt new techniques, making it possible both to diversify production and grow more with less. Another key requirement consists of clear signals from policymakers, especially where land and water are limited, about the priority use of these resources — for example, irrigating low-value cereals to bolster food security versus applying the water to higher value crops and importing staple cereals.
Toward a sustainable dietary revolution
Future-proofing the global food system requires bold steps. Policy and research need to support a double transformation, centered on nutrition and sustainability.
CGIAR works toward nutritional transformation of our food system through numerous global partnerships. We give high priority to improving cereal crop systems and food products, because of their crucial importance for a growing world population. Recognizing that this alone will not suffice for healthy diets, we also strongly promote greater dietary diversity through our research on various staple crops and production systems and by raising public awareness of more balanced and nutritious diets.
To help achieve a sustainability transformation, CGIAR researchers and partners have developed a wide array of techniques that use resources more efficiently, enhance the resilience of food production in the face of climate change and reduce greenhouse gas emissions, while achieving sustainable increases in crop yields. At the same time, we are generating new evidence on which techniques work best under what conditions to target the implementation of these solutions more effectively.
The ultimate impact of our work depends crucially on the growing resolve of developing countries to promote better diets and more sustainable food production through strong policies and programs. CGIAR is well prepared to help strengthen these measures through research for development, and we are confident that our work on cereals, with continued donor support, will have high relevance, generating a wealth of innovations that help drive the transformation of global food systems.

Data from microsatellites can be used to detect and double the impact of sustainable interventions in agriculture at large scales, according to a new study led by the University of Michigan (U-M).
By being able to detect the impact and target interventions to locations where they will lead to the greatest increase or yield gains, satellite data can help increase food production in a low-cost and sustainable way.
According to the team of researchers from U-M, the International Maize and Wheat Improvement Center (CIMMYT), and Stanford and Cornell universities, finding low cost ways to increase food production is critical given that feeding a growing population and increasing the yields of crops in a changing climate are some of the greatest challenges of the coming decades.
“Being able to use microsatellite data, to precisely target an intervention to the fields that would benefit the most at large scales will help us increase the efficacy of agricultural interventions,” said lead author Meha Jain, assistant professor at the U-M School for Environment and Sustainability.
Microsatellites are small, inexpensive, low-orbiting satellites that typically weigh 100 kilograms (220 pounds) or less.
“About 60-70% of total world food production comes from smallholders, and they have the largest field-level yield gaps,” said Balwinder Singh, senior researcher at CIMMYT.
To show that the low-cost microsatellite imagery can quantify and enhance yield gains, the researchers conducted their study in smallholder wheat fields in the Eastern Indo-Gangetic Plains in India.
They ran an experiment on 127 farms using a split-plot design over multiple years. In one half of the field, the farmers applied nitrogen fertilizer using hand broadcasting, the typical fertilizer spreading method in this region. In the other half of the field, the farmers applied fertilizer using a new and low-cost fertilizer spreader.
To measure the impact of the intervention, the researchers then collected the crop-cut measures of yield, where the crop is harvested and weighed in field, often considered the gold standard for measuring crop yields. They also mapped field and regional yields using microsatellite and Landsat satellite data.
They found that without any increase in input, the spreader resulted in 4.5% yield gain across all fields, sites and years, closing about one-third of the existing yield gap. They also found that if they used microsatellite data to target the lowest yielding fields, they were able to double yield gains for the same intervention cost and effort.
“Being able to bring solutions to the farmers that will benefit most from them can greatly increase uptake and impact,” said David Lobell, professor of earth system science at Stanford University. “Too often, we’ve relied on blanket recommendations that only make sense for a small fraction of farmers. Hopefully, this study will generate more interest and investment in matching farmers to technologies that best suit their needs.”
The study also shows that the average profit from the gains was more than the amount of the spreader and 100% of the farmers were willing to pay for the technology again.
Jain said that many researchers are working on finding ways to close yield gaps and increase the production of low-yielding regions.
“A tool like satellite data that is scalable and low cost and can be applied across regions to map and increase yields of crops at large scale,” she said.
The study is published in the October issue of Nature Sustainability.

New study provides an extensive field-test validation of existing
genetic markers for thousand grain weight; finds both surprises and promising
To meet the demand for wheat from a rising and quickly
urbanizing population, wheat yields in farmers’ fields must increase by an
estimated 1.5% each year through 2030.
Of all the factors that influence yield, grain weight is the
trait that is most stable and heritable for use in breeding improved wheat
varieties. Breeders measure this by thousand grain weight (TGW).
Over the years, molecular scientists have made efforts to
identify genes related to increased TGW, in order to speed up breeding through
marker-assisted selection (MAS). Using MAS, breeders can select parents that contain
genes related to the traits they are looking for, increasing the likelihood
they will be passed on and incorporated in a new variety.
There have been some limited successes in these efforts: in
the past years, a few genes related to increased TGW have been cloned, and a
set of genetic markers have been determined to be used for MAS. However, the
effects of most of these candidate genes (CGs) have not yet been validated in
diverse sets of wheat germplasm throughout the world that represent the full
range of global wheat growing environments.
A group of wheat geneticists and molecular breeders from the International Maize and Wheat Improvement Center (CIMMYT) has recently conducted a thorough study to confirm the effects of the favorable alleles reported for these genes on TGW in CIMMYT wheat, — and to identify new genetic determinants of this desired trait.
They found some good news and some bad.
First, the good news: focusing on more than 4000 lines of CIMMYT
wheat germplasm they found 15 haplotype blocks significantly associated with
TGW. Four haplotype blocks associated
with TGW were also associated with grain yield – a grand prize for breeders,
because in general the positive
association of grain yield with TGW is less profound and sometimes even
negative. However, of the 14 genes that had been previously reported to
increase TGW, only one in CIMMYT’s 2015-2016 Elite Yield Trial and two in Wheat
Associative Mapping Initiative panel were shown to have significant TGW
The scientists also found that the alleles — pairs of genes
on a chromosome that determine heredity – that were supposedly favorable to TGW
actually decreased it. These candidate
genes also appear to vary in their TGW effects with genetic background and/or
Thus, these findings also provide a foundation for more detailed
investigations, opening the door for more studies on the genetic background
dependence and environment sensitivity of the known candidate genes for
indicate that it will be challenging to use MAS based on these existing markers
across individual breeding programs,” said Deepmala Sehgal, CIMMYT wheat geneticist
and the primary author of the study.
However, efforts to identify new genetic determinants of TGW
were promising. The authors’ study of
CIMMYT germplasm found one locus on chromosome 6A that showed increases of up
to 2.60 grams in TGW and up to 258 kilograms per hectare in grain yield.
This discovery expands opportunities for developing
diagnostic markers to assist in multi-gene pyramiding – a process that can derive
new and complementary allele combinations for enhanced wheat TGW and grain
Most of all, the study highlights the strong need for better
and more validation of the genes related to this and other traits, so that
breeders can be sure they are using material that is confirmed to increase
wheat grain weight and genetic yield.
“Our findings are very promising for future efforts to
efficiently develop more productive wheat in both grain weight and grain yield,”
said Sehgal. “This ultimately means more bread on household tables throughout
