As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.
Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.
Nominations are now open for the 2019 MAIZE Youth Innovators Awards – Africa! These awards are part of the efforts that the CGIAR Research Program on Maize (MAIZE) is undertaking to promote youth participation in maize-based agri-food systems. These awards recognize the contributions of young women and men below 35 years of age who are implementing innovations in African maize-based agri-food systems, including research for development, seed systems, agribusiness, and sustainable intensification.
Young people are the key to ensuring a food-secure future and agricultural sustainability. However, rural youth face many challenges related to unemployment, underemployment and poverty. According to the Food and Agriculture Organization (FAO) of the United Nations, facilitating young people’s participation in agriculture has the potential to drive widespread rural poverty reduction among young people and adults alike. In Africa, where over 300 million smallholder-farming families grow and consume maize as a staple crop, the human population stands at 1.2 billion people, 60 percent of whom are below the age of 25.
The MAIZE Youth Innovators Awards aim to identify young innovators who can serve to inspire other young people to get involved in maize-based agri-food systems. Part of the vision is to create a global network of young innovators in maize-based systems from around the world.
Award recipients will be invited to attend the annual Stress Tolerant Maize for Africa (STMA) project meeting in Lusaka, Zambia, from May 7 to May 9, where they will receive their awards and will be given the opportunity to present their work. The project meeting and award ceremony will also allow these young innovators to network and exchange experiences with MAIZE researchers and partners.

The developing world’s appetite for wheat is growing swiftly, driven in part by rising incomes, rapid urbanization and the expansion of families where both spouses work outside the house, according to a recent seminar by two international experts.
“Our research is picking up significant shifts in demand among cereals, including the increasing popularity of wheat in Asia and sub-Saharan Africa,” said Khondoker Mottaleb, socioeconomist for the International Maize and Wheat Improvement Center (CIMMYT), speaking at a seminar at the center on December 11, 2018.
In preliminary results of a study using household data from six countries in Asia and five in sub-Saharan Africa, Mottaleb and his associate, Fazleen Binti Abdul Fatah, senior lecturer at the University of Technology MARA, Malaysia, found that the households of both regions will eat more wheat by 2030, mainly in place of rice in Asia and of maize and other coarse grain cereals in Africa.
Speedy urbanization, higher incomes, population growth, and allied lifestyle changes are all driving this trend, said Fazleen. “Many urban women are working, so families are transitioning to bread and other convenient wheat-based foods and processed foods.”
A typical case according to Mottaleb is that of Bangladesh, a country whose population at 160 million is half that of the United States but with a geographical area equivalent to the US state of Ohio. The per capita GDP of Bangladesh grew from US$360 to US$1,516 during 2000-2017, and more than 35 percent of the country’s inhabitants now live in cities.
Meeting demand for wheat in Bangladesh
A 2018 paper by Mottaleb and fellow CIMMYT researchers shows that wheat consumption will increase substantially in Bangladesh by 2030 and the country needs to expand production or increase imports to meet the growing demand.
“The country purchases nearly 70 percent of its wheat at an annual cost near or exceeding US$1 billion, depending on yearly prices,” said Mottaleb. “Wheat prices are relatively low and wheat markets have been relatively stable, but if yields of a major wheat exporting country suddenly fall, say, from pest attacks or a drought, wheat markets would destabilize and prices would spike, as occurred in 2008 and 2011.”
In a 2018 study, the United Kingdom’s Agriculture and Horticulture Development Board (AHDB) cautioned that declining wheat cropping area worldwide and significant stockpiling by China — which holds nearly half the world’s wheat stocks but does not export any grain — were masking serious risk in global wheat markets.
A recent report ranked Bangladesh as the world’s fifth largest wheat importer. Since 2014-15 domestic wheat consumption there has increased by 57 percent from 4.9 million metric ton to 7.7 million metric tons. Last December, the Food and Agriculture Organization (FAO) of the United Nations forecast Bangladesh wheat import requirements of 6 million tons for this year — 34 percent above the previous five-year average following steady increases since 2012-13.
“The prevailing narrative has wealthier and more urban consumers shifting from basic foods to higher value foods, and this is doubtless occurring,” said Fazleen, “but our work shows a more nuanced scenario. In the traditional rice consuming economies in Asia, rural households are also eating more wheat, due to rapid dietary transformations.”
For Bangladesh, the researchers propose growing additional wheat on fallow and less-intensively-cropped land, as well as expanding the use of newer, high-yielding and climate-smart wheat varieties.
“Our work clearly shows the rising popularity of wheat across Asia and Africa,” said Mottaleb. “We urge international development agencies and policymakers to enhance wheat production in suitable areas, ensuring food security for the burgeoning number of people who prefer wheat and reducing dependence on risky wheat grain markets.”

Researcher Tamaya Peressini performs disease evaluations 10 days post infection at CIMMYT’s glasshouse facilities.
In 2018, Tamaya Peressini, from the Queensland Alliance for Agriculture and Food Innovation (QAAFI), a research institute of the University of Queensland (UQ), travelled to CIMMYT in Mexico as part of her Honours thesis research, focused on a disease called tan spot in wheat.
Tan spot is caused by the pathogen Pyrenophora triciti-repentis (Ptr) and her project aimed to evaluate the resistance of tan spot in wheat to global races to this pathogen.
“The germplasm I’m studying for my thesis carries what is known as adult plant resistance (or APR) to tan spot, which has demonstrated to be a durable source of resistance in other wheat pathosystems such as powdery mildew,” Peressini said.
Symptoms of tan spot on wheat plants.
Tan spot is prevalent worldwide, and in Australia causes the most yield loss out of the foliar wheat diseases. In Australia, there is only one identified pathogen race that is prevalent, called Ptr Race 1. For Ptr Race 1, the susceptibility gene Tsn1 in wheat is the main factor that results in successful infection in Ptr strains that carry Toxin A. However, globally it is a more difficult problem, as there are seven other pathogen races that consist of different combinations of necrotrophic toxins. Hence, developing cultivars that are multi-race resistant to Ptr presents a significant challenge to breeders, as multiple resistant genes would be required for resistance to other pathogens.
“At CIMMYT, I evaluated the durability of APR I identified in plant material in Australia by inoculating with a local strain of Ptr and also with a pathogen that shares ToxA: Staganospora nodorum,” Peressini explained.
“The benefit of studying this at CIMMYT was that I had access to different strains of the pathogen which carry different virulence factors of disease, I was exposed to international agricultural research and, importantly, I was able to create research collaborations that would allow the APR detected in this population to have the potential to reach developing countries to assist in developing durably resistant wheat cultivars for worldwide deployment.”
Recent work in Dr Lee Hickey’s laboratory in Queensland has identified several landraces from the Vavilov wheat collection that exhibited a novel resistance to tan spot known as adult plant resistance (APR). APR has proven to be a durable and broad-spectrum source of resistance in wheat crops, namely with the Lr34 gene which confers resistance to powdery mildew and leaf stem rust of wheat.
“My research is focused on evaluating this type of resistance and identifying whether it is resistant to multiple pathogen species and other races of Ptr. This is important to the Queensland region, as the northern wheat belt is significantly affected by tan spot disease. Introducing durable resistance genes to varieties in this region would be an effective pre-breeding strategy because it would help develop crop varieties that would have enhanced resistance to tan spot should more strains reach Australia. Furthermore, it may provide durable resistance to other necrotrophic pathogens of wheat,” Peressini said.
The plant material Peressini studied in her honors thesis was a recombinant inbred line (RIL) population, with the parental lines being the APR landrace — carries Tsn1 — and the susceptible Australian cultivar Banks — also carries Tsn1. To evaluate the durability of resistance in this population to other strains of Ptr, this material along with the parental lines of the population and additional land races from the Vavilov wheat collection were sent to CIMMYT for Tamaya to perform a disease assay.
“At CIMMYT I evaluated the durability of APR identified in plant material in Australia by inoculating with a local strain of Ptr and also with a pathogen that shares ToxA: Staganospora nodorum. After infection, my plant material was kept in 100 per cent humidity for 24 hours (12 hours light and 12 hours dark) and then transferred back to regular glasshouse conditions. At 10 days post infection I evaluated the resistance in the plant material.”
From the evaluation, the APR RIL line demonstrated significant resistance compared to the rest of the Australian plant material against both pathogens. The results are highly promising, as they demonstrate the durability of the APR for both pre-breeding and multi-pathogen resistance breeding. Furthermore, this plant material is now available for experimental purposes at CIMMYT, where further trials can validate how durable the resistance is to other necrotrophic pathogens and also be deployed worldwide and be tested against even more strains of Ptr.
“During my visit at CIMMYT I was able to immerse myself in the Spanish language and take part in professional seminars, tours, lab work and field work around the site. A highlight for me was learning to prepare and perform toxin infiltrations for an experiment comparing the virulence of different strains of spot blotch,” Peressini said.
During her stay in Mexico, Peressini had a chance to visit the pyramids of Teotihuacán and other cultural landmarks.
“I also formed valuable friendships and research partnerships from every corner of the globe and had valuable exposure to the important research underway at CIMMT and insight to the issues that are affecting maize and wheat growers globally. Of course, there was also the chance to travel on weekends, where I was able to experience the lively Mexican culture and historical sites – another fantastic highlight to the trip!”
“I would like to thank CIMMYT and Dr Pawan Singh for hosting me and giving the opportunity to learn, grow and experience the fantastic research that is performed at CIMMYT and opportunities to experience parts of Mexico. The researchers and lab technicians were all so friendly and accommodating. I would also like to thank my supervisor Dr Lee Hickey for introducing this project collaboration with CIMMYT. Lastly, I would like to thank the Crawford Fund Queensland Committee for funding this visit; not only was I able to immerse myself in world class plant pathology research, I have been given valuable exposure to international agricultural research that will give my research career a boost in the right direction,” Peressini concluded.
A new report by more than 30 world-leading experts in health and environmental sustainability offers a roadmap for a global food system that provides a healthy, sustainable diet for the world’s 10 billion people by 2050.
Published jointly by EAT, a global non-profit foundation founded to catalyze a food system transformation, and The Lancet, the world’s leading medical journal, the report links diets with human health and environmental sustainability. It lays out five global scientific strategies to achieve healthy diets and sustainable food production by the year 2050: shifting diets, producing healthy food, sustainably intensifying food production, improving land and water governance, and reducing food loss and waste.
The report urges substantial dietary shifts and specific courses of action from consumers, policymakers, businesses and government agencies alike to transform the world’s food system. As the report states, “Without action, the world risks failing to meet the UN Sustainable Development Goals (SDGs) and the Paris Agreement, and today’s children will inherit a planet that has been severely degraded and where much of the population will increasingly suffer from malnutrition and preventable disease.”
The report emphasizes eating diets heavy in fruits, nuts, vegetables and whole grains and light on meat, as current Western-style diets are already straining the global food system’s environmental impact and pushing planetary limits. According to CIMMYT consultant and leading nutritionist Julie Miller Jones of St. Catherine University, USA, eating whole grain foods reduces obesity and the risk of almost all chronic diseases.
Given that the food system drives nearly 30 percent of greenhouse gas emissions, occupies 40 percent of land and causes 80 percent of biodiversity loss, increasing healthy, resource-saving foods and reducing unhealthy and unsustainably produced foods is an essential step in securing future environmental sustainability.
The founder and executive chair of EAT, Gunhild Stordalen, commented at the report’s launch event January 17 in Olso, Norway: “No single sector, technology or entity can fix it alone but, for the first time, we have a clear direction and initial targets to align and guide our actions.”
As the world heats up and water grows scarce, threatening the productivity of humankind’s preferred crops, breeder Marcela Carvalho Andrade and her colleagues at the International Maize and Wheat Improvement Center (CIMMYT) are working to toughen maize, drawing resilience traits from landraces, the forerunners of modern maize.
For decades, scientists have sought to utilize the hardiness of maize landraces, which evolved over millennia of farmer selection for adaptation to diverse and sometimes harsh local settings in Mexico, Central and South America.
But crossing elite varieties with landraces brings along wild traits that are difficult and costly to purge, including lower grain yields, excessive tallness or a tendency to fall over in strong winds. For this and for their genetic complexity, landraces are seldom used directly in breeding programs, according to Andrade.
Crosses that home in on genetically complex traits
“Our strategy is to cross selected landraces with elite maize lines, thus developing improved lines that can be directly incorporated and recycled in breeding programs,” explained Andrade, who joined CIMMYT in 2016.
The traits sought include better resilience under high temperatures, drought conditions or the attacks of rapidly-evolving crop diseases. “All these features will be critical for the future productivity of maize,” said Andrade.
One of the world’s three most important crops, maize contributes over 20% of the calories in human diets in 21 low-income countries, as well as being used in industry, biofuels, and feed for livestock and poultry.
Andrade and the maize breeding team develop new lines that carry a 75 percent genetic contribution from the elite source and 25 percent from a landrace. The aim she said is to get the good components from both sides, while broadening maize’s genetic diversity for use by breeders and ultimately farmers.
The resulting lines and hybrids are tested for yield, resilience and overall agronomic performance, under both normal growing conditions and “stressed” environments; for example, in plots grown at sites with high temperatures or reduced water availability.
“We can thus identify landraces that offer traits of interest, as well as generating improved breeding lines to strengthen the resilience of elite maize without reducing its yield,” said Andrade, noting that the research employs conventional cross-pollination and selection.
According to Andrade, CIMMYT has carried out large-scale molecular analysis of its maize seed collections, which number around 28,000 and comprise landraces from 70 countries.
“Over the past years, CIMMYT has used genetic diversity analyses of its maize collections to select landraces for use in drought tolerance breeding or for finding lines that are resistant to newly important diseases such as Maize Lethal Necrosis or Tar Spot,” she explained. “Genetic diversity analysis allows us to narrow the number of candidate landrace sources that we need to cross and assess in the field.”
The viral disease Maize Lethal Necrosis (MLN) has devastated crops in eastern Africa since its appearance there in 2011.
The researchers have also found landrace sources of resilience against Tar Spot Complex, a maize disease of the Americas that can cause 50 percent or greater yield losses in infected crops.
Benefiting breeding and farmers
Andrade said the breeding team expects to release a first wave of landrace-derived, improved maize lines in 2019, some featuring enhanced drought tolerance and others that provide better resistance to Tar Spot.
“The lines we offer will be freely available to breeders worldwide and must yield well and show superior resilience,” Andrade explained. “They will have reasonable agronomics—ear and plant height and standability, for example. The lines will not be perfect, but breeders won’t hesitate to use them because we’ve ensured that they are superior for at least one crucial trait and reasonably competitive for most other traits.”
From Brazil to the world
Growing up in a small town and having direct contact with her father’s dairy farm in Minas Gerais, a mainly rural state in Brazil, Andrade finds her CIMMYT work enormously satisfying. “My dad and a few uncles were farmers and complained some years that their crops didn’t yield well,” she says. “I knew I wanted to help them somehow.”
Andrade obtained Bachelor and Master’s degrees in agronomy/plant science from the Universidade Federal de Lavras (UFLA), one of Brazil’s premier institutions of higher education. She later completed a Doctorate in Genetics and Plant Breeding at UFLA, in partnership with Ohio State University.
She credits CIMMYT maize scientist Terry Molnar, her supervisor and mentor, with teaching her the complex ins and outs of maize breeding. “I am a plant breeder and worked previously with vegetables, but I learned the practical aspects of maize breeding from Terry.”
Looking ahead, Andrade sees herself continuing as a plant breeder. “I don’t see myself working in anything else. I would eventually like to lead my own program but, at this point in my career, I’m happy to help transfer landrace traits to modern maize varieties.”

A new study explores how conservation agriculture in southern Africa supports spider populations and diversity in fields, which could help mitigate pest damage and potentially lead to higher yields for farmers. According to the Food and Agriculture Organization of the United Nations (FAO), herbivorous insects such as aphids, caterpillars and weevils destroy about one fifth of the world’s total crop production each year. Spiders can help keep voracious pests in-check, but conventional farming practices (e.g. tilling, crop residue removal and monoculture) can harm or drastically reduce these beneficial bio-control agents.
There are more than 45,000 identified spider species around the world. From glaciers to tropical rainforests, they inhabit every terrestrial ecosystem on earth. Some can even live in tidal zones, and at least one species inhabits fresh water. While we tend to associate spiders with webs, only about 50 percent of the species catch their prey this way; the rest hunt on plants, on the ground or below it, using a variety of tactics such as stalking, stabbing, crushing – even seduction.
Although spiders have been around for 300 million years, some species are at risk of extinction due to habitat loss and fragmentation. Drastic reductions in vegetation – whether from a new parking lot or a tilled field – removes the food source that attracts their prey. Bare ground exposes their nesting sites and themselves, which makes it harder to hunt and easier to be hunted by birds and small mammals.
At the Chinhoyi University of Technology experimental farm in Zimbabwe, a team of researchers aimed to determine the response of spiders under different agricultural practices. Conventional farmers often prepare their fields for planting by physically breaking up and inverting the top 6-10 inches of soil. This practice of ploughing prepares a fine soil tilth, which makes it easier to plant; it breaks up and buries weeds, and reduces soil compaction to aerate the soil. But tilling also increases topsoil erosion from wind and water. It accelerates soil carbon decomposition, reduces soil water infiltration and disrupts microorganisms living in the soil, including beneficial insects and spiders.
The researchers conducted two experiments over the 2013/2014 and 2014/2015 cropping seasons to see how tilling, crop residue retention (i.e. leaving stalks and post-harvest organic matter in the field), fertilizer application and weeding affected ground- and plant-wandering spider species. They hypothesized that spider abundance and diversity would increase with lower levels of soil disturbance and more plant cover.
The results showed direct seeding into no-till soil increased the abundance of spiders and the diversity of species. Mulching also showed a positive effect. Contrary to their hypotheses and results from temperate regions, the application of fertilizer and intense weeding did not affect the spider community. The researchers attributed this to the difference in climatic conditions (tropical vs. temperate) of this study in southern Africa.
“Often the government’s and farmer’s immediate reaction to a crop pest issue is to apply a pesticide, but we can make use of biological control agents, which may be cheaper and less damaging for the environment,” says Christian Thierfelder, a co-author of the study. Thierfelder is a cropping systems agronomist and conservation agriculture specialist with the International Maize and Wheat Improvement Center (CIMMYT) with long-term experience in sustainable intensification.
“Spiders, ants and beetles all do a really good job with little or no cost to the farmer,” he adds. “For us, it’s quite fascinating to see simple agronomic practices to affect and control crop pests. This also provides new avenues of dealing with the fall armyworm, an invasive species which has devastated crops across the majority of sub-Saharan Africa countries.”
A robust number of studies from Europe, Australia and North America have shown the link between conservation agriculture and biodiversity, but Thierfelder says that research on biodiversity in agronomic systems is relatively new in southern Africa. While the study in Zimbabwe helps fill this gap, more research is needed to show the connection between the abundance of spiders, beetles and ants with the suppression of insect pest activity.
This research was jointly funded by Chinhoyi University of Technology (CUT) and the German Academic Exchange Program (DAAD). The CGIAR Research Program on Maize (MAIZE) supported this study through Christian Thierfelder’s contributions.

Ethiopia is Africa’s third largest producer of maize, after Nigeria and South Africa. Although the country produces around 6.5 million tons annually, the national average maize yield is relatively low at 3.5 tons compared to the attainable yield of 8.5 tons. This high yield gap — the difference between attainable and actual yields — can be attributed to a number of factors, including crop varieties used, farm management practices, and plant density.
The Taking Maize Agronomy to Scale (TAMASA) project aims to narrow maize yield gaps in Ethiopia, Nigeria and Tanzania through the development and scaling out of decision-support tools, which provide site-specific recommendations based on information held in crop and soil databases collected from each country. These help farmers to make decisions based on more accurate variety and fertilizer recommendations, and can contribute to improving maize production and productivity.
One such tool is Nutrient Expert, a free, interactive computer-based application. It can rapidly provide nutrient recommendations for individual farmers’ fields in the absence of soil-testing data. The tool was developed by the International Plant Nutrition Institute in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), the International Institute of Tropical Agriculture (IITA), and research and extension service providers.
Nutrient Expert user interface.
In Ethiopia, regional fertilizer recommendations are widely used, but soil fertility management practices can vary greatly from village to village and even between individual farmers. This can make it difficult for farmers or extension agents to receive accurate information tailored specifically to their needs. Nutrient Expert fills this gap by incorporating information on available fertilizer blends and giving customized recommendations for individual fields or larger areas, using information on current farmer practices, field history and local conditions. It can also provide advice on improved crop management practices such as planting density and weeding, thereby helping farmers to maximize net returns on their investment in fertilizer.
Data calibration was based on the results of 700 multi-location nutrient omission trials conducted in major maize production areas in Ethiopia, Nigeria and Tanzania. These trials were designed as a diagnostic tool to establish which macro-nutrients are limiting maize growth and yield, and determine other possible constraints.
In Ethiopia, CIMMYT scientists working for the TAMASA project conducted nutrient omission trials on 88 farmer fields in Jimma, Bako and the Central Rift Valley in 2015 to produce a version of Nutrient Expert suitable for the country. Researchers trialed the app on six maize-belt districts in Oromia the following year, in which Nutrient Expert recommendations were compared with soil-test based and regional ones.
Researchers found that though the app recommended lower amounts of phosphorus and potassium fertilizer, overall maize yields were comparable to those in other test sites. In Ethiopia, this reduction in the use of NPK fertilizer resulted in an investment saving of roughly 80 dollars per hectare.
Results from Nutrient Expert trials in Ethiopia, Nigeria and Tanzania showed improved yields, fertilizer-use efficiency and increased profits, and the app has since been successfully adapted for use in developing fertilizer recommendations that address a wide variety of soil and climatic conditions in each of the target countries.
The World Bank’s 2016 Digital Dividends report states that we are currently “in the midst of the greatest information and communications revolution in human history.” This shifting digital landscape has significant implications for the ways in which stakeholders in the agricultural sector generate, access and use data. Amidst Africa’s burgeoning technology scene, CIMMYT’s TAMASA project demonstrates the transformative power of harnessing ICTs for agricultural development.

Maize is the most important staple food crop in sub-Saharan Africa, providing food security and a source of income to more than 200 million households. Nonetheless, maize yields in this region rank among the lowest worldwide.
The International Maize and Wheat Improvement Center (CIMMYT) launched the International Maize Improvement Consortium for Africa (IMIC-Africa) in May 2018, to better engage with a committed set of partners from the public and private sector, and to achieve enhanced maize yields in Africa.
Members of IMIC-Africa share a vision: meeting the challenges of maize production by scaling out and fully exploiting the potential of improved climate-resilient and stress-tolerant varieties in sub-Saharan Africa.
Cultivated on over 35 million hectares of typically rainfed land across sub-Saharan Africa, maize is subject to the vagaries of climate, suffering occasional to frequent drought stress. Other regional challenges include poor soil quality, characterized by nitrogen deficiency, and the ongoing threat of transboundary pathogens and pests, such as the voracious fall armyworm. In addition, farmers generally have inadequate access to improved seed that could help them achieve higher yields.
Although the challenges are complex, the effective use of improved, climate-resilient and multiple-stress-tolerant maize varieties has achieved tangible results in this region. Elite drought-tolerant (DT) maize hybrids developed by CIMMYT have demonstrated at least 25-30 percent grain yield advantage over non-DT maize varieties in sub-Saharan Africa under drought stress. CIMMYT has also derived elite heat-tolerant maize hybrids for sub-Saharan Africa, and during the recent outbreak of maize lethal necrosis (MLN), the rapid development and deployment of elite MLN-resistant hybrids was instrumental in the containment of this threat to eastern Africa.
Modelled on its successful counterpart initiatives in Asia (IMIC-Asia) and Latin America (IMIC-LatAm), there is hope that IMIC-Africa will follow a similar pattern of success.
The consortium is comprised of a diverse array of member institutions, including seed companies, national programs and foundations.
Its key objective is to enhance members’ capacity for germplasm development in their own breeding programs through provision of early generation or advanced maize lines. The subsequent multi-location testing of elite pre-commercial maize hybrids throughout sub-Saharan Africa by members will serve to identify products that can advance to commercialization and deployment.
“IMIC-Africa has a growing membership aimed at formalizing the sharing of maize lines under development with public and private maize breeding programs,” said CIMMYT scientist and Africa regional representative Stephen Mugo. “The consortium will also support a vibrant germplasm testing network, offer opportunities for training and cross learning among members, and grant access to other special services offered by CIMMYT including MLN testing, doubled haploid development and molecular quality assurance/quality control.”
The work of the consortium will ultimately benefit the farming community through the targeted development of maize varieties that express traits jointly identified and prioritized by consortium members and that are specifically adapted to the suite of agro-ecologies in sub-Saharan Africa. Traits of relevance include tolerance to abiotic stresses, disease and insect-pest resistance and higher yielding hybrids.
“IMIC-Africa will contribute to food security in Africa by broadening access to and use of stress-tolerant improved maize germplasm as well as strengthening maize breeding programs, thus improving farmers’ access to improved maize varieties,” Mugo explained.
Membership of IMIC-Africa is open to all organized and registered private commercial seed companies, corporations, and organized and registered public agencies or organizations involved in maize crop research and improvement, hybrid seed production or maize seed marketing.

The main focus of the Sustainable and Resilient Farming Systems Intensification (SRFSI) project is on conservation agriculture technologies. Since farmers may face an increase in weeds after adopting zero-till planters, however, more research is needed about how farmers are dealing with weed.
One of the research objectives of the project is to understand farmers’ knowledge, perception, and practices of conservation agriculture. To this end, researchers are using the Photovoice methodology in Cooch Behar (West Bengal, India), Rongpur (Bangladesh) and Sunsari (Nepal) to collect relevant data on weed management practices.
Photovoice is a visual qualitative research method that allows people to express their perspectives through photographs. Photography can be used for evaluation purposes, through storytelling exercises.
On December 6-7, 2019, field technicians in Bangladesh, India and Nepal participated in a training about this methodology. They learned the rationale of Photovoice, its technical and logistic aspects, as well as the ethical considerations and the need to collect consent forms.
Participants also learned how to take pictures of inter-row cultivation and weeds on the farm, and how to confirm the geolocation of the farm.
Worth a thousand words
Using the Photovoice method, 30 households will be explored, including their labor allocation and decision-making dynamics around the implementation of conservation agriculture practices.
The effectiveness of this approach will emerge as smallholder farmers present their perspectives through photographs accompanied by their narratives.
Activities will be monitored on weekly basis.
The SRFSI project, funded by the Australian Centre for International Agricultural Research (ACIAR) and led by the International Maize and Wheat Improvement Center, is set to improve the productivity, profitability and sustainability of smallholder agriculture in the Eastern Gangetic Plains of Bangladesh, India and Nepal, by promoting sustainable intensification based on conservation agriculture technologies.
Visiting researcher Fazleen Abdul Fatah is studying the growing importance of maize and wheat in emerging economies.
Fazleen Abdul Fatah credits a number of factors for her interest in agricultural research, from a childhood spent in a small town in one of Malaysia’s main rice farming areas, where the neighborhood revolved around agriculture, to supporting lecturers and professors who encouraged her interests during her undergraduate studies. “My experiences as an intern in the Philippines and visiting commercial farms in Germany and Japan as a student also shaped my motivation to work in sustainable agriculture and rural development, and ultimately I’d like to be able to influence food and agriculture policy,” she says.
Now a senior lecturer in the Faculty of Plantation and Agrotechnology at Universiti Teknologi MARA (UITM) in Malaysia, where she specializes in agricultural economics, trade and policy. For the past three months she has been based at the global headquarters of the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, where she is conducting research into food consumption patterns.
Having previously completed an internship with the International Rice Research Institute (IRRI) in the Philippines, Abdul Fatah was keen to gain more experience within the CGIAR system. After graduating from the University of Gottingen, Germany, with a PhD in Agriculture Trade Policy, her interest in the growing importance of maize and wheat in emerging economies prompted her to apply for a research opportunity at CIMMYT.
“I’m very interested in understanding how current shifts in food consumption patterns might affect the consumption of cereals in Indonesia and Malaysia.” Her previous research focused on the shift to cereals from food items such as meat, fish, or vegetables, but Abdul Fatah notes that few studies document shifts between cereals. “Rice is typically the main staple food crop for Malaysians,” she explains, “but changes in diets, incomes, and urbanization mean that people are shifting towards maize and wheat. What I’ve found more striking from my research is that in some areas people are actually consuming more wheat than rice, which means there are going to be some interesting decisions for policy makers to consider in the near future, especially in terms of import strategies.”
Abdul Fatah presented her initial research findings at CIMMYT, where she updated colleagues on her efforts to analyze consumption patterns for major cereals in 11 developing countries in Africa and Asia using government household surveys and World Bank datasets. She hopes to continue this line of research once she returns to UITM and is currently working on a paper based on case studies from Indonesia and Malaysia.
In 2018, our editors continued to cover exciting news and events related to maize and wheat science around the world. Altogether, we published more than 200 stories.
It is impossible to capture all of the places and topics we reported on, but here are some highlights and our favorite stories of the year.
Thank you for being a loyal reader of CIMMYT’s news and features. We are already working on new stories and platforms for 2019. Stay tuned!
In response to the spread of the fall armyworm across Africa, CIMMYT and its partners published a technical guide for integrated pest management. Produced by international experts, it offers details on the best management practices to help smallholder farmers effectively and safely control the pest while simultaneously protecting people, animals and the environment.
This year we launched our new podcast, Cobs & Spikes, where you can listen to stories from the field, interviews and explainers.
The most popular episode so far was about blue maize, a distinctive feature of Mexico’s food culture. Valued for its rich flavor and texture, it is also catching the attention of some food processing companies and high-end culinary markets. CIMMYT researchers are helping Mexican farmers tap into two emerging markets that could boost incomes while conserving culture and biodiversity.
A review of scientific studies on cereal grains and health showed that gluten- or wheat-free diets are not inherently healthier for the general populace and may actually put individuals at risk of dietary deficiencies.
Based on a compilation of 12 reports, eating whole grains is actually beneficial for brain health and associated with reduced risk of diverse types of cancer, coronary disease, diabetes, hypertension, obesity and overall mortality.
Mechanized agricultural services have traditionally only been used by large-scale farmers who could afford them, but small and medium-sized machines are fast becoming affordable options for family farmers through the advent of service providers. An increasing number of young people across eastern and southern Africa are creating a stable living as entrepreneurs, providing agricultural mechanization services.
CIMMYT is offering training courses to promote mechanization in Ethiopia, Kenya, Tanzania and Zimbabwe. Trainings equip entrepreneurs with essential business skills and knowledge, tailored to rural environments, so they can support farmers with appropriate mechanization services that sustainably intensify their production.

In a scientific breakthrough, the International Wheat Genome Sequencing Consortium presented an annotated reference genome with a detailed analysis of gene content among subgenomes and the structural organization for all the chromosomes. The research was published on Science.
Over 46 percent of children under five in Guatemala suffer from chronic malnutrition. More than 40 percent of Guatemala’s rural population is deficient in zinc, an essential micronutrient that plays a crucial role in pre-natal and post-natal development and is key to maintaining a healthy immune system.
CIMMYT is working with partners HarvestPlus and Semilla Nueva to reduce malnutrition and zinc deficiency in the country, through the development and deployment of Guatemala’s first biofortified zinc-enriched maize.
CIMMYT was present at the African Green Revolution Forum in Kigali, Rwanda. Leaders discussed practical ways to transform policy declarations into impact on the ground, at a time when farmers are facing the challenge of climate change and the threat of emerging pests and diseases.
On the occasion of this event, CIMMYT’s Director General, Martin Kropff, and the Regional Representative for Africa, Stephen Mugo, authored an op-ed on agricultural innovation in Africa, published by Thomson Reuters (in English) and Jeune Afrique (in French).

An international team of scientists applied genome-wide association analysis for the first time to study the genetics that underlie grain zinc concentrations in wheat.
Analyzing zinc concentrations in the grain of 330 bread wheat lines across diverse environments in India and Mexico, the researchers uncovered 39 new molecular markers associated with the trait, as well as two wheat genome segments that carry important genes for zinc uptake, translocation, and storage in wheat.

A study in Ethiopia found that wheat grown in areas closer to the forest had more nutrients, like zinc and protein. Soils in these areas are rich in organic matter — about 1% higher — due to decomposing trees and plants, as well as manure of livestock grazed in the forest.
Increasing organic matter by 1 percent was associated with an increase in zinc equivalent to meet the daily needs of 0.2 additional people per hectare and an increase in protein equivalent to meeting the daily needs of 0.1 additional people per hectare. These modest increases in soil organic matter contribute a small, but important, increase in nutrients found in wheat.
Although these nutrient increases are not enough to address hidden hunger on their own, they reveal how healthy soils are an additional tool — alongside diet diversity and the biofortification of food — to fight malnutrition.
In 2018 we published our latest annual report, highlighting CIMMYT’s global work and collaboration with partners. It features infographics and case studies from Bangladesh, Ethiopia, Haiti, Mexico and Pakistan.
It is a good way to understand how CIMMYT’s science improves livelihoods around the world.

A man in his early 20s walked the winding roads of Sajiara village, Dumuria upazila, Khulna District in Bangladesh. His head hanging low, he noticed darkness slowly descending and then looked up to see an old farmer wrapping up his own daily activities. With traditional tools in hand, the farmer looked exhausted. The young man, Raju Sarder, considered that there had to be a better way to farm to alleviate his drudgery and that of others in the community.
Determined to act, Raju set out to meet Department of Agricultural Extension (DAE) officials the very next day. They informed him about the Mechanization and Irrigation project of the Cereal Systems Initiative for South Asia (CSISA MI). They also introduced him to the project’s most popular technologies, namely the power tiller operated seeder, reaper and axial flow pumps, all of which reduce labor costs and increase farming efficiency.
Raju found the reaper to be the most interesting and relevant for his work, and contacted a CSISA representative to acquire one.
The first challenge he encountered was the cost — the equivalent of $1,970 — which as a small-scale farmer he could not afford. CSISA MI field staff assured him that his ambitions were not nipped in the bud and guided him in obtaining a government subsidy and a loan of $1,070 from TMSS, one of CSISA MI’s micro financing partners. Following operator and maintenance training from CSISA MI, Raju began providing reaping services to local smallholder rice and wheat farmers.
He noticed immediately that he did not have to exert himself as much as before but actually gained time for leisure and his production costs dwindled. Most remarkably, for reaping 24 hectares Raju generated a profit of $1,806; a staggering 15 times greater than what he could obtain using traditional, manual methods and enough to pay back his loan in the first season.
“There was a time when I was unsure whether I would be able to afford my next meal,” said Raju, “but it’s all different now because profits are pouring in thanks to the reaper.”
As a result of the project and farmers’ interest, field labor in Raju’s community is also being transformed. Gone are the days when farmers toiled from dawn to dusk bending and squatting to cut the rice and wheat with rustic sickles. Laborious traditional methods are being replaced by modern and effective mechanization. Through projects such as CSISA MI, CIMMYT is helping farmers like Raju to become young entrepreneurs with a bright future. Once poor laborers disaffected and treated badly in their own society, these youths now walk with dignity and pride as significant contributors to local economic development.
The importance of maize in Asian cropping systems has grown rapidly in recent years, with several countries registering impressive growth rates in maize production and productivity. However, increasing and competing demands — food, feed, and industry — highlight the continued need to invest in maize research for development in the region. Maize experts from around the world gathered to discuss these challenges and how to solve them at the 13th Asian Maize Conference and Expert Consultation on Maize for Food, Feed, Nutrition and Environmental Security, held from October 8 to 10, 2018, in Ludhiana, Punjab, India.
More than 280 delegates from 20 countries attended the conference. Technical sessions and panel discussions covered diverse topics such as novel tools and strategies for increasing genetic gains, stress-resilient maize, sustainable intensification of maize-based cropping systems, specialty maize, processing and value addition, and nutritionally enriched maize for Asia.
The international conference was jointly organized by the Indian Council of Agricultural Research (ICAR), the International Maize and Wheat Improvement Center (CIMMYT), the Indian Institute of Maize Research (ICAR-IIMR), Punjab Agricultural University (PAU), the CGIAR Research Program on Maize (MAIZE), and the Borlaug Institute for South Asia (BISA).
In Asia, maize is rapidly growing in its importance, due to high demand. Maize productivity in the region is growing by 5.2 percent annually compared to a global average of 3.5 percent. However, this is not enough. “Asia produces nearly 80 million tons of maize annually, but demand will be double by the year 2050,” said Martin Kropff, CIMMYT director general, in his opening address at the conference. “We need to produce two times more maize in Asia, using two times less inputs, including water and nutrients. Climatic extremes and variability, especially in South and South East Asia, will make this challenge more difficult. Continued funding for maize research is crucial. We need to work together to ensure that appropriate innovations reach the smallholder farmers.”

Climate-resilient maize and sustainable intensification
A major theme emphasized at the conference was climate resilience in maize-based systems. South Asia is a hotspot for vulnerability due to climate change and climate variability, which poses great risks to smallholder farmers. “Climate resilience cannot be brought by only a single technology — it has to be through a judicious mix of several approaches,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.
Great advances have been made in developing climate-resilient maize for Asia since the last Asian Maize Conference, held in 2014. Many new heat- and drought-tolerant maize varieties have been developed through various projects, such as the Heat Stress Tolerant Maize for Asia (HTMA), and Affordable, Accessible, Asian (AAA) maize projects. Through the HTMA project, over 50 CIMMYT-derived elite heat-tolerant maize hybrids have been licensed to public and private sector partners in Asia during the last three years, and nine heat-tolerant maize hybrids have been released so far in Bangladesh, India and Nepal.
Sustainable intensification of maize-based farming systems has also helped farmers to increase yields while reducing environmental impact, through conservation agriculture and scale-appropriate mechanization. Simple technologies are now available to reduce harvest time by up to 80 percent and hired labor costs by up to 60 percent. Researchers across the region are also working to strengthen the maize value chains.

Science and appropriate technologies
CIMMYT has been focusing on developing and deploying new technologies that can enhance the efficiency of maize breeding programs; these include doubled haploid (DH) technology, high-throughput field-based phenotyping, and genomics-assisted breeding. The conference emphasized on the need for Asian institutions to adapt such new tools and technologies in maize breeding programs.
Another topic of interest was the fall armyworm, an invasive insect pest that has spread through 44 countries in Africa and was recently reported in India for the first time. “This pest can migrate very quickly and doesn’t require visas and passports like we do. It will travel, and Asian nations need to be prepared,” Prasanna said. “However, there is no need for alarm. We will be looking at lessons learned from other regions and will work together to control this pest.”
In addition to grain for food and feed, specialty maize varieties can provide beneficial economic alternatives for smallholder maize farmers. Conference participants had the opportunity to hear from Indian farmers Kanwal Singh Chauhan and Yugandar Y, who have effectively adopted specialty maize varieties, such as baby corn, sweet corn and popcorn, into life-changing economic opportunities for farming communities. They hope to inspire other farmers in the region to do the same.
On October 10, conference delegates participated in a maize field day organized at the BISA farm in Ladhowal, Ludhiana. Nearly 100 improved maize varieties developed by CIMMYT, ICAR and public and private sector partners were on display, in addition to scale-appropriate mechanization options, decision support tools, and precision nutrient and water management techniques.
The conference concluded with a ceremony honoring the winners of the 2018 MAIZE-Asia Youth Innovators Award. The awards were launched in collaboration between the CGIAR Research Program on Maize and YPARD (Young Professionals for Agricultural Development) to recognize the contributions of innovative young women and men who can inspire fellow youth to get involved in improving maize-based agri-food systems in Asia. Winners of the first edition of the awards include Dinesh Panday of Nepal, Jie Xu of China, Samjhana Khanal of Nepal, and Vignesh Muthusamy of India.

Support for smallholder farmers to trial and select sustainable practices suited to their varying conditions is essential to build resilient farms needed to feed Africa’s soaring population, said economist Paswel Marenya at the Second African Congress on Conservation Agriculture in Johannesburg this October.
Farmers face different agroecological, socioeconomic and institutional environments across Africa. The mounting challenges brought by climate change also vary from place to place. Family farmers are born innovators, with government and industry support they can develop a resilient farming system that works for them, said the researcher from the International Maize and Wheat Improvement Center (CIMMYT).
One of the emerging paradigms of sustainable agriculture resilient to climatic changes is conservation agriculture — defined by minimal soil disturbance, crop residue retention and diversification through crop rotation. Although not a one-size-fits-all approach, it is a promising framework to be applied and adapted to meet farmers’ unique contexts, he said.
“Conservation agriculture’s potential to conserve soils, improve yields and limit environmental impacts makes it one of the elements that should be given prominence in efforts to secure sustainable and resilient farming in Africa,” he told audiences at the conference dedicated to discuss conservation agriculture systems as the sustainable basis for regional food security.
“Research shows that with a network of appropriate support, farmers can access the tools and knowledge to experiment, learn, adapt and adopt these important principles of conservation agriculture,” he said.
“Their farming can thus evolve to practices that have low environmental impacts, diversify their cropping including intercropping maize with legumes, and test affordable machinery for efficient, timely and labor-saving operations. In the end, each farmer and farming community have the ability to tailor a conservation agriculture-based system based on what works best given their unique socioeconomic settings,” said Marenya.
Trialing sustainable practices leads to adoption
Through the project over 235,000 farming households in the region have trialed sustainable practices reporting positive results of improved soil fertility, reduced labor costs, and increased food production and maize yields despite erratic weather, said collaborating investigator Custudio George from the Mozambique Institute of Agricultural Research.
“The majority of these farmers have gone on to adopt their preferred practices throughout their whole farm and now actively promote conservation agriculture to other farmers,” he added
Women undertake the majority of agricultural activities in sub-Saharan Africa. When they are empowered to try sustainable practices they overwhelmingly adopt those technologies identifying them as an economically viable way to overcome challenges and increase household food security, said Maria da Luz Quinhentos, who is an agronomist with the Mozambique Institute of Agricultural Research.

Forming networks to support farmer resilience
The research project took a multidisciplinary approach bringing together sociologists, economists, agronomists and breeders to study how maize-legume conservation agriculture-based farming can best benefit farmers in seven countries; including Ethiopia, Kenya, Malawi, Mozambique, Tanzania and Uganda.
In this vein, the project sought to connect farmers with multi-sector actors across the maize-legume value chain through Innovation platforms. Innovation Platforms, facilitated by SIMLESA, are multi-stakeholder forums connecting farmer groups, agribusiness, government extension, policy makers and researchers with the common goal to increase farm-level food security, productivity and incomes through the promotion of maize-legume intercropping systems.
“Having a network of stakeholders allows farmers to test and adopt conservation agriculture-based techniques without the risk they would have if they tried and failed alone,” said Michael Misiko who studies farmer adoption as part of SIMLESA.
“Farmers form groups to work with governments to gain access to improved seed, learn new farming practices and connect with local agribusinesses to develop markets for their produce,”
“When new problems arise stakeholders in local and regional innovation platforms can diagnose barriers and together identify mutual solutions,” he said.
Researchers and governments learn from innovation platforms and can use results to recommend productive climate-smart practices to other farmers in similar conditions, Misiko added.
Climate-smart agriculture key to achieve Malabo Declaration
The results from SIMLESA provide African governments with evidence to develop policies that achieve the Malabo Declaration to implement resilient farming systems to enhance food security in the face of a growing climate risks, said Marenya.
If these smallholders are to keep up with food demand of a population set to almost double by 2050 while overcoming challenges they need productive and climate-resilient cropping systems.
CIMMYT research identifies that the defining principles of conservation agriculture are critical but alone are not enough to shield farmers from the impacts of climate change. Complementary improvements in economic policies, markets and institutions — including multi-sectoral linkages between smallholder agriculture and the broader economy — are required to make climate-resilient farming systems more functional for smallholder farmers in the short and long term, said Marenya.

Nearly 3,000 smallholder wheat farmers throughout Pakistan will begin to sow seed of newer, high-yielding, disease-resistant wheat varieties and spread the seed among their peers in 2019, through a dynamic initiative that is revitalizing the contribution of science-based innovation for national agriculture.
Some 73 tons of seed of 15 improved wheat varieties recently went out to farmers in the provinces of Baluchistan, Gilgit Baltistan, Khyber Pakhtunkhwa, Punjab and Sindh, as part of the Agricultural Innovation Program (AIP), an initiative led by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the US Agency for International Development (USAID).
“Our main goal is to help farmers replace outdated, disease-susceptible wheat varieties,” said Muhammad Imtiaz, CIMMYT scientist and country representative for Pakistan who leads the AIP. “Studies have shown that some Pakistan farmers grow the same variety for as long as 10 years, meaning they lose out on the superior qualities of newer varieties and their crops may fall victim to virulent, rapidly evolving wheat diseases.”
With support from CIMMYT and partners, participating farmers will not only enjoy as much as 20 percent higher harvests, but have agreed to produce and share surplus seed with neighbors, thus multiplying the new varieties’ reach and benefits, according to Imtiaz.
He said the new seed is part of AIP’s holistic focus on better cropping systems, including training farmers in improved management practices for wheat.
Wheat is Pakistan’s number-one food crop. Farmers there produce over 25 million tons of wheat each year — nearly as much as the entire annual wheat output of Africa or South America.
Annual per capita wheat consumption in Pakistan averages over 120 kilograms, among the highest in the world and providing over 60 percent of Pakistanis’ daily caloric intake.
The seed distributed includes varieties that offer enhanced levels of grain zinc content. The varieties were developed by CIMMYT in partnership with HarvestPlus, a CGIAR research program to study and deliver biofortified foods.
According to a 2011 nutrition survey, 39 percent of children in Pakistan and 48 percent of pregnant women suffer from zinc deficiency, leading to child stunting rates of more than 40 percent and high infant mortality.

“I am very excited to be part of Zincol-16 seed distribution, because its rich ingredients of nutrition will have a good impact on the health of my family,” said Munsif Ullah, a farmer from Swabi District, Khyber Pakhtunkhwa province.
Other seed distributed includes that of the Pakistan-13 variety for rainfed areas of Punjab, Shahkar-13 for the mountainous Gilgit-Baltistan, Ehsan-16 for rainfed areas in general, and the Umeed-14 and Zardana varieties for Baluchistan.
All varieties feature improved resistance to wheat rust diseases caused by fungi whose strains are mutating and spreading quickly in South Asia.
CIMMYT and partners are training farmers in quality seed production and setting up demonstration plots in farmers’ fields to create awareness about new varieties and production technologies, as well as collecting data to monitor the varieties’ performance.
They are also promoting resource-conserving practices such as balanced applications of fertilizer based on infrared sensor readings, ridge planting, and zero tillage. These innovations can save water, fertilizer, and land preparation costs, not to mention increasing yields.
“CIMMYT’s main focus in Pakistan is work with national wheat researchers to develop and spread better wheat production systems,” Imtiaz explained. “This includes improved farming practices and wheat lines that offer higher yields, disease resistance, and resilience under higher temperatures and dry conditions, as well as good end-use quality.”
CIMMYT’s partners in AIP include the National Rural Support Program (NRSP), the Lok Sanjh Foundation, the Village Friends Organization (VFO), the Aga Khan Rural Support Program (AKRSP), the National Agricultural Research Council (NARC) Wheat Program, the Wheat Research Institute (WRI) Faisalabad and Sakrand centers, AZRI-Umarkot, Kashmala Agro Seed Company, ARI-Quetta, BARDC-Quetta, and Model Farm Services Center, KP.
A new report by more than 30 world-leading experts in health and environmental sustainability offers a roadmap for a global food system that provides a healthy, sustainable diet for the world’s 10 billion people by 2050.
