An international team of scientists has provided a sweeping new analysis of the benefits of conservation agriculture for crop performance, water use efficiency, farmers’ incomes and climate action across a variety of cropping systems and environments in South Asia.

The analysis, published today in Nature Sustainability, is the first of its kind to synthesize existing studies on conservation agriculture in South Asia and allows policy makers to prioritize where and which cropping systems to deploy conservation agriculture techniques. The study uses data from over 9,500 site-year comparisons across South Asia.

According to M.L. Jat, a principal scientist at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the study, conservation agriculture also offers positive contributions to the Sustainable Development Goals of no poverty, zero hunger, good health and wellbeing, climate action and clean water.

“Conservation agriculture is going to be key to meet the United Nations Sustainable Development Goals,” echoed JK Ladha, adjunct professor at the University of California, Davis, and co-author of the study.

Scientists from CIMMYT, the Indian Council of Agricultural Research (ICAR), the University of California, Davis, the International Rice Research Institute (IRRI) and Cornell University looked at a variety of agricultural, economic and environmental performance indicators — including crop yields, water use efficiency, economic return, greenhouse gas emissions and global warming potential — and compared how they correlated with conservation agriculture conditions in smallholder farms and field stations across South Asia.

Results and impact on policy

Researchers found that many conservation agriculture practices had significant benefits for agricultural, economic and environmental performance indicators, whether implemented separately or together. Zero tillage with residue retention, for example, had a mean yield advantage of around 6%, provided farmers almost 25% more income, and increased water use efficiency by about 13% compared to conventional agricultural practices. This combination of practices also was shown to cut global warming potential by up to 33%.

This comes as good news for national governments in South Asia, which have been actively promoting conservation agriculture to increase crop productivity while conserving natural resources. South Asian agriculture is known as a global “hotspot” for climate vulnerability.

“Smallholder farmers in South Asia will be impacted most by climate change and natural resource degradation,” said Trilochan Mohapatra, Director General of ICAR and Secretary of India’s Department of Agricultural Research and Education (DARE). “Protecting our natural resources for future generations while producing enough quality food to feed everyone is our top priority.”

“ICAR, in collaboration with CIMMYT and other stakeholders, has been working intensively over the past decades to develop and deploy conservation agriculture in India. The country has been very successful in addressing residue burning and air pollution issues using conservation agriculture principles,” he added.

With the region’s population expected to rise to 2.4 billion, demand for cereals is expected to grow by about 43% between 2010 and 2050. This presents a major challenge for food producers who need to produce more while minimizing greenhouse gas emissions and damage to the environment and other natural resources.

“The collaborative effort behind this study epitomizes how researchers, policy-makers, and development practitioners can and should work together to find solutions to the many challenges facing agricultural development, not only in South Asia but worldwide,” said Jon Hellin, leader of the Sustainable Impact Platform at IRRI.

Include small indigenous production systems to improve rural livelihoods

Researchers from the Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee, United States, and the International Maize and Wheat Improvement Center (CIMMYT) in Texcoco, Mexico, describe why it is important for technical assistance to build upon indigenous farming knowledge and include women if programs are to succeed in tackling poverty and hunger in rural, Mesoamerican communities. Their findings, describing recent work in the Guatemalan Highlands, are recently published in Nature Sustainability.

According to government figures, 59% of Guatemalans live in poverty, concentrated in indigenous rural areas, such as the Western Highlands. Many factors contribute to pervasive malnutrition and a lack of employment opportunities for people in the Highlands. Recent crop failures associated with atypical weather events have exacerbated food shortages for Highland farm communities.

In early 2019, 90% of recent migrants to the southern border of the United States were from Guatemala, a majority of those from regions such as the Western Highlands. When they are unable to produce or purchase enough food to feed their families, people seek opportunities elsewhere. Historically, sugar cane and coffee industries offered employment but as prices for these commodities fall, fewer options for work are available within the region.

Indigenous peoples in the Highlands have been using a traditional agricultural production system called milpa for thousands of years. The milpa system involves growing maize together with climbing beans, squash, and other crops on a small plot of land. The maize plants support the growth of the climbing beans; the beans enrich soil through biological nitrogen fixation; and squash and other crops protect the soil from erosion, retain water, and prevent weeds.

However, frequent crop failures, declining farm sizes, and other factors result in low household production, forcing families to turn to non-agricultural sources of income or assistance from a family member working abroad. Studies have shown that as household income declines, dietary diversity decreases, which exacerbates undernutrition.

In prior decades, technical assistance for agriculture in Central America focused on larger farms and non-traditional export crops. The researchers recommend inclusion of indigenous communities to enhance milpa systems. Nutrition and employment options can be improved by increasing crop diversity and adopting improved seed varieties that are adapted to the needs of the local communities. This approach requires investments that recognize and advance ancestral knowledge and the role of indigenous women in milpa systems. The Nature Sustainability commentary highlights that technical assistance needs to include women and youth and should increase resilience in production systems to climate change, related weather events, pests, and disease.

“Improving linkages among local farmers, extensionists, students, and researchers is critical to identify and implement opportunities that result in more sustainable agricultural landscapes,” said Keith Kline, senior researcher at Oak Ridge National Laboratory. “For example, improved bean varieties have been developed that provide high-yields and disease resistance, but if they grow too aggressively, they choke out other milpa crops. And successful adoption of improved varieties also depends on whether flavor and texture meet local preferences.”

Strengthening institutions to improve agricultural development, health care, security, education can help create stronger livelihoods and provide the Western Highlands community with a foundation for healthier families and economic stability. As more reliable options become available to feed one’s family, fewer Guatemalans will feel pressured to leave home.

New international partnership to identify and develop resistance to dangerous wheat disease

CIMMYT and JAAS representatives signed the agreement to establish a screening facility for Fusarium head blight in Nanjing, China.
CIMMYT and JAAS representatives signed the agreement to establish a screening facility for Fusarium head blight in Nanjing, China.

The CGIAR Research Program on Wheat (WHEAT), led by the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agriculture in the Dry Areas (ICARDA), recently announced a partnership with the Jiangsu Academy of Agricultural Sciences (JAAS) in China to open a new screening facility for the deadly and fast-spreading fungal wheat disease Fusarium head blight, or FHB.

The new facility, based near the JAAS headquarters in Nanjing, aims to capitalize on CIMMYT’s world-class collection of disease-resistant wheat materials and the diversity of the more than 150,000 wheat germplasm in its Wheat Germplasm Bank to identify and characterize genetics of sources of resistance to FHB and, ultimately, develop new FHB-resistant wheat varieties that can be sown in vulnerable areas around the world.

“The participation of JAAS in the global FHB breeding network will significantly contribute to the development of elite germplasm with good FHB resistance,” said Pawan Singh, head of wheat pathology for CIMMYT.

“We expect that in 5 to 7 years, promising lines with FHB resistance will be available for deployment by both CIMMYT and China to vulnerable farmers, thanks to this new station.”

Fusarium head blight is one of the most dangerous wheat diseases. It can cause up to 50% yield loss and produce severe mycotoxin contamination in food and feed, which affects farmers in the form of increased health care and veterinary care costs, and reduced livestock production.

Even consuming low to moderate amounts of Fusarium mycotoxins may impair intestinal health, immune function and fitness. Deoxynivalenol (DON), a mycotoxin the fungus inducing FHB produces, has been linked to symptoms including nausea, vomiting, and diarrhea. In livestock, Fusarium mycotoxin consumption exacerbates infections with parasites, bacteria and viruses — such as occidiosis in poultry, salmonellosis in pigs and mice, colibacillosis in pigs, necrotic enteritis in poultry and swine respiratory disease.

In China, the world’s largest wheat producer, Fusarium head blight is the most important biotic constraint to production.

The disease is extending quickly beyond its traditionally vulnerable wheat growing areas in East Asia, North America, the southern cone of South America, Europe and South Africa — partly as a result of global warming, and partly due to otherwise beneficial, soil-conserving farming practices such as wheat-maize rotation and reduced tillage.

“Through CIMMYT’s connections with national agricultural research systems in developing countries, we can create a global impact for JAAS research, reaching the countries that are expected to be affected the expansion of FHB epidemic area,” said Xu Zhang, head of Triticeae crops research group at the Institute of Food Crops of the Jiangsu Academy of Agricultural Sciences.

The new collaborative effort will target Fusarium head blight research but could potentially expand to research on other wheat diseases as well. Wheat blast, for example, is a devastating disease that spread from South America to Bangladesh in 2016. Considering the geographical closeness of Bangladesh and China, a collaboration with CIMMYT, as one of the leading institutes working on wheat blast, could have a strong impact.

Although the platform is new, the two institutions have a longstanding relationship. The bilateral collaboration between JAAS and CIMMYT began in early 1980s with a shuttle breeding program between China and Mexico to speed up breeding for Fusarium head blight resistance. The two institutions also conducted extensive germplasm exchanges in the 1980s and 1990s, which helped CIMMYT improve resistance to Fusarium head blight, and helped JAAS improve wheat rust resistance.

Currently, JAAS and CIMMYT are working on Fusarium head blight under a project funded by the National Natural Science Foundation of China called “Elite and Durable Resistance to Wheat Fusarium Head Blight” that aims to deploy resistance genes/QTL in Chinese and CIMMYT germplasm and for use in wheat breeding.

Healthy diets feature both whole- and refined-grain foods, new study shows

Grain-based foods — both whole-grain and refined, from which the bran has been removed — are a key part of healthy diets, according to a study published in the science journal Advances in Nutrition.

The study, co-authored by Julie Miller Jones of St. Catherine University, Carlos Guzman of the Universidad de Córdoba and Hans-Joachim Braun of the International Maize and Wheat Improvement Center (CIMMYT), reviewed findings of more than 100 research papers from nutrition and medical journals as well as national health recommendations. It presents evidence for positive health impacts from diverse diets that include not more than 50% carbohydrates and the right mix of grain-based foods.

“Epidemiological studies consistently show that eating three 30-gram portions of whole-grain foods — say, half a cup of oats — per day is associated with reduced chronic disease risk,” said Miller Jones, Professor Emerita at St. Catherine University and first author of the study. “But refined-grain foods — especially staple, enriched or fortified ones of the ‘non-indulgent’ type — also provide key vitamins and minerals that are otherwise lacking in people’s diets.”

“Cereal grains help feed the world by providing millions of calories per hectare and large amounts of plant-based protein,” said Braun, director of CIMMYT’s Global Wheat Program and the CGIAR Research Program on Wheat. “They are affordable, shelf stable, portable, versatile, and popular, and will play a key role as the world transitions to plant-based diets to meet future food needs.”

Folate fortification of refined grains has helped reduce the incidence of spina bifida, anencephaly, and other birth defects, according to Miller Jones. “And despite contributing to high sugar intake, ready-to-eat breakfast cereals are typically consumed with nutritious foods such as milk, yogurt, and fruit,” she added.

All grain-based foods, refined and whole, are good sources of dietary fiber, which is essential for sound health but critically lacking in modern diets. “Only 4 percent of the U.S. population, for example, eats recommended levels of dietary fiber,” she said.

Obesity, Type 2 diabetes, high blood pressure, and other illnesses from unbalanced diets and unhealthy habits are on the rise in countries such as the U.S., driving up health care expenditures. The annual medical costs of obesity alone there have been estimated at nearly $150 billion.

“Dietary choices are determined partly by lifestyle but also co-vary with daily habits and personal traits,” Miller Jones explained. “People who eat more whole-grain foods are more likely to exercise, not smoke, and have normal body weights, as well as attaining higher levels of education and socioeconomic status.”

According to the study, recommendations for grain-based foods need to encourage a healthy number of servings and replacing half of refined-grain foods with whole-grain products, as well as providing clearer and unbiased definitions of both types of grain-based foods.

TEXCOCO, Mexico — Using field and mobile phone surveillance data together with forecasts for spore dispersal and environmental suitability for disease, an international team of scientists has developed an early warning system which can predict wheat rust diseases in Ethiopia. The cross-disciplinary project draws on expertise from biology, meteorology, agronomy, computer science and telecommunications.

Reported this week in Environmental Research Letters, the new early warning system, the first of its kind to be implemented in a developing country, will allow policy makers and farmers all over Ethiopia to gauge the current situation and forecast wheat rust up to a week in advance.

The system was developed by the University of Cambridge, the UK Met Office, the Ethiopian Institute of Agricultural Research (EIAR), the Ethiopian Agricultural Transformation Agency (ATA) and the International Maize and Wheat Improvement Center (CIMMYT). It works by taking near real-time information from wheat rust surveys carried out by EIAR, regional research centers and CIMMYT using a smartphone app called Open Data Kit (ODK).

This is complemented by crowd-sourced information from the ATA-managed Farmers’ Hotline. The University of Cambridge and the UK Met Office then provide automated 7-day advance forecast models for wheat rust spore dispersal and environmental suitability based on disease presence.

All of this information is fed into an early warning unit that receives updates automatically on a daily basis. An advisory report is sent out every week to development agents and national authorities. The information also gets passed on to researchers and farmers.

Timely alerts

“If there’s a high risk of wheat rust developing, farmers will get a targeted SMS text alert from the Farmers’ Hotline. This gives the farmer about three weeks to take action,” explained Dave Hodson, principal scientist with CIMMYT and co-author of the research study. The Farmers’ Hotline now has over four million registered farmers and extension agents, enabling rapid information dissemination throughout Ethiopia.

Ethiopia is the largest wheat producer in sub-Saharan Africa but the country still spends in excess of $600 million annually on wheat imports. More can be grown at home and the Ethiopian government has targeted to achieve wheat self-sufficiency by 2023.

“Rust diseases are a grave threat to wheat production in Ethiopia. The timely information from this new system will help us protect farmers’ yields, and reach our goal of wheat self-sufficiency,” said EIAR Director Mandefro Nigussie.

Wheat rusts are fungal diseases that can be dispersed by wind over long distances, quickly causing devastating epidemics which can dramatically reduce wheat yields. Just one outbreak in 2010 affected 30% of Ethiopia’s wheat growing area and reduced production by 15-20%.

The pathogens that cause rust diseases are continually evolving and changing over time, making them difficult to control. “New strains of wheat rust are appearing all the time — a bit like the flu virus,” explained Hodson.

In the absence of resistant varieties, one solution to wheat rust is to apply fungicide, but the Ethiopian government has limited supplies. The early warning system will help to prioritize areas at highest risk of the disease, so that the allocation of fungicides can be optimized.

The cream of the crop

The early warning system puts Ethiopia at the forefront of early warning systems for wheat rust. “Nowhere else in the world really has this type of system. It’s fantastic that Ethiopia is leading the way on this,” said Hodson. “It’s world-class science from the UK being applied to real-world problems.”

“This is an ideal example of how it is possible to integrate fundamental research in modelling from epidemiology and meteorology with field-based observation of disease to produce an early warning system for a major crop,” said Christopher Gilligan, head of the Epidemiology and Modelling Group at the University of Cambridge and a co-author of the paper, adding that the approach could be adopted in other countries and for other crops.

“The development of the early warning system was successful because of the great collaborative spirit between all the project partners,” said article co-author Clare Sader-Allen, currently a regional climate modeller at the British Antarctic Survey.

“Clear communication was vital for bringing together the expertise from a diversity of subjects to deliver a common goal: to produce a wheat rust forecast relevant for both policy makers and farmers alike.”

Microsatellite data can help double impact of agricultural interventions

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 of 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 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 the International Maize and Wheat Improvement Center (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.

Large-scale genomics will improve the yield, climate-resilience, and quality of bread wheat, new study shows

Using the full wheat genome map published in 2018, combined with data from field testing of wheat breeding lines in multiple countries, an international team of scientists has identified significant new chromosomal regions for wheat yield and disease resistance and created a freely-available collection of genetic information and markers for more than 40,000 wheat lines.

Reported today in Nature Genetics, the results will speed up global efforts to breed more productive and climate-resilient varieties of bread wheat, a critical crop for world food security that is under threat from rising temperatures, rapidly-evolving fungal pathogens, and more frequent droughts, according to Philomin Juliana, wheat scientist at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new study.

“This work directly connects the wheat genome reference map with wheat lines and extensive field data from CIMMYT’s global wheat breeding network,” said Juliana. “That network in turn links to over 200 breeding programs and research centers worldwide and contributes to yield and other key traits in varieties sown on nearly half the world’s wheat lands.”

The staple food for more than 2.5 billion people, wheat provides 20% of human dietary calories and protein worldwide and is critical for the nutrition and food security of hundreds of millions of poor persons in regions such as North Africa and South Asia.

“Farmers and societies today face new challenges to feed rising and rapidly-urbanizing populations, and wheat epitomizes the issues,” said Ravi Singh, CIMMYT wheat breeder and corresponding author of the study. “Higher temperatures are holding back yields in major wheat-growing areas, extreme weather events are common, crop diseases are spreading and becoming more virulent, and soil and water are being depleted.”

Juliana said the study results help pave the way to apply genomic selection, an approach that has transformed dairy cow husbandry, for more efficient wheat breeding.

“Molecular markers are getting cheaper to use; meanwhile, it’s very costly to do field testing and selection involving many thousands of wheat plants over successive generations,” Juliana said. “Genome-wide marker-based selection can help breeders to precisely identify good lines in early breeding generations and to test plantlets in greenhouses, thereby complementing and streamlining field testing.”

The new study found that genomic selection could be particularly effective in breeding for wheat end-use quality and for resistance to stem rust disease, whose causal pathogen has been evolving and spreading in the form of highly-virulent new races.

The new study also documents the effectiveness of the global public breeding efforts by CIMMYT and partners, showing that improved wheat varieties from this work have accumulated multiple gene variants that favor higher yields, according to Hans-Joachim Braun, director of CIMMYT’s global wheat program.

“This international collaboration, which is the world’s largest publicly-funded wheat breeding program, benefits farmers worldwide and offers high-quality wheat lines that are released directly to farmers in countries, such as Afghanistan, that are unable to run a full-fledged wheat breeding program,” Braun explained.

The study results are expected to support future gene discovery, molecular breeding, and gene editing in wheat, Braun said.

Together with more resource-efficient cropping systems, high-yielding and climate-resilient wheat varieties will constitute a key component of the sustainable intensification of food production described in Strategy 3 of the recent EAT-Lancet Commission recommendations to transform the global food system.

Extensive use of wild grass-derived “synthetic hexaploid wheat” adds diversity and resilience to modern bread wheat

In a new study, scientists have found that genome segments from a wild grass are present in more than one in five of elite bread wheat lines developed by the International Maize and Wheat Improvement Center (CIMMYT).

Scientists at CIMMYT and other research institutes have been crossing wild goat grass with durum wheat — the wheat used for pasta — since the 1980s, with the help of complex laboratory manipulations. The new variety, known as synthetic hexaploid wheat, boosts the genetic diversity and resilience of wheat, notoriously vulnerable due to its low genetic diversity, adding novel genes for disease resistance, nutritional quality and heat and drought tolerance.

The study, which aimed to measure the effect of these long-term efforts using state-of-the-art molecular technology, also found that 20% of CIMMYT modern wheat lines contain an average of 15% of the genome segments from the wild goat grass.

“We’ve estimated that one-fifth of the elite wheat breeding lines entered in international yield trials has at least some contribution from goat grass,” said Umesh Rosyara, genomic breeder at CIMMYT and first author of the paper, which was published in Nature Scientific Reports. “This is much higher than expected.”

Although the synthetic wheat process can help bring much-needed diversity to modern wheat, crossing with synthetic wheat is a complicated process that also introduces undesirable traits, which must later be eliminated during the breeding process.

“Many breeding programs hesitate to use wild relatives because undesirable genomic segments are transferred in addition to desirable segments,” said Rosyara. “The study results can help us devise an approach to quickly eliminate undesirable segments while maintaining desirable diversity.”

CIMMYT breeding contributions are present in nearly half the wheat sown worldwide, many of such successful cultivars have synthetic wheat in the background, so the real world the impact is remarkable, according to Rosyara.

“With this retrospective look at the development and use of synthetic wheat, we can now say with certainty that the best wheat lines selected over the past 30 years are benefiting from the genes of wheat’s wild relatives,” he explained. “Even more, using cutting-edge molecular marker technology, we should be able to target and capture the most useful genes from wild sources and better harness this rich source of diversity.”

Modern breeders tread in nature’s footsteps

The common bread wheat we know today arose when an ancient grain called emmer wheat naturally cross-bred with goat grass around 10,000 years ago. During this natural crossing, very few goat grass genes crossed over, and as a result, current bread wheat is low in diversity for the genome contributed by goat grass. Inedible and considered a weed, goat grass still has desirable traits including disease resistance and tolerance to climate stresses.

Scientists sought to broaden wheat’s genetic diversity by re-enacting the ancient, natural cross that gave rise to bread wheat, crossing improved durum wheat or primitive emmer with different variants of goat grass. The resulting synthetic wheats were crossed again with improved wheats to help remove undesirable wild genome segments.

Once synthetic wheat is developed, it can be readily crossed with any elite wheat lines thus serving as a bridge to transfer diversity from durum wheat and wild goat grass to bread wheat. This helps breeders develop high yielding varieties with desirable traits for quality varieties and broad adaption.

CIMMYT is the first to use wheat’s wild relatives on such a large scale, and the synthetic derivative lines have been used by breeding programs worldwide to develop popular and productive bread wheat varieties. One example, Chuanmai 42, released in China in 2003, stood as the leading wheat variety in the Sichuan Basin for over a decade. Other synthetic derivative lines such as Sokoll and Vorobey appear in the lineage of many successful wheat lines, contributing crucial yield stability — the ability to maintain high yields over time under varying conditions.

The successful, large-scale use of genes from wheat’s wild relatives has helped broaden the genetic diversity of modern, improved bread wheat nearly to the level of the crop’s heirloom varieties. This diversity is needed to combat future environmental, pest, and disease challenges to the production of a grain that provides 20% of the calories consumed by humans worldwide.

Scientists use DNA fingerprinting to gauge the spread of modern wheat in Afghanistan

Wheat is Afghanistan’s number-one staple crop, but the country doesn’t grow enough and must import millions of tons of grain each year to satisfy domestic demand.
Wheat is Afghanistan’s number-one staple crop, but the country does not grow enough and must import millions of tons of grain each year to satisfy domestic demand.

Despite the severe social and political unrest that constrain agriculture in Afghanistan, many farmers are growing high-yielding, disease resistant varieties developed through international, science-based breeding and made available to farmers as part of partnerships with national wheat experts and seed producers.

These and other findings have emerged from the first-ever large-scale use of DNA fingerprinting to assess Afghanistan farmers’ adoption of improved wheat varieties, which are replacing less productive local varieties and landraces, according to a paper published yesterday in the science journal BMC Genomics.

The study is part of an activity supported between 2003 and 2018 by the Australian Department of Foreign Affairs and Trade, through which the Agricultural Research Institute of Afghanistan and the International Maize and Wheat Improvement Center (CIMMYT) introduced, tested, and released improved wheat varieties.

“As part of our study, we established an extensive ‘reference library’ of released varieties, elite breeding lines, and Afghan wheat landraces,” said Susanne Dreisigacker, wheat molecular breeder at CIMMYT and lead author of the new paper.

“We then compared wheat collected on farmers’ fields with the reference library. Of the 560 wheat samples collected in 4 provinces during 2015-16, farmers misidentified more than 40%, saying they were of a different variety from that which our DNA analyses later identified.”

Wheat is the most important staple crop in Afghanistan — more than 20 million of the country’s rural inhabitants depend on it — but wheat production is unstable and Afghanistan has been importing between 2 and 3 million tons of grain each year to meet demand.

Over half of the population lives below the poverty line, with high rates of malnutrition. A key development aim in Afghanistan is to foster improved agronomic practices and the use of high quality seed of improved wheat varieties, which together can raise yields by over 50%.

“Fungal diseases, particularly yellow rust and stem rust, pose grave threats to wheat in the country,” said Eric Huttner, research program manager for crops at the Australian Centre for International Agricultural Research (ACIAR) and co-author of the present paper. “It’s crucial to know which wheat varieties are being grown where, in order to replace the susceptible ones with high-performing, disease resistant varieties.”

Varietal adoption studies typically rely on questionnaires completed by breeders, extension services, seed producers, seed suppliers, and farmers, but such surveys are complicated, expensive, and often inaccurate.

“DNA fingerprinting resolves uncertainties regarding adoption and improves related socioeconomic research and farm policies,” Huttner explained, adding that for plant breeding this technology has been used mostly to protect intellectual property, such as registered breeding lines and varieties in more developed economies.

This new study was commissioned by ACIAR as a response to a request from the Government of Afghanistan for assistance in characterizing the Afghan wheat gene bank, according to Huttner.

“This provided the reference library against which farmers’ samples could be compared,” he explained. “Accurately identifying the varieties that farmers grow is key evidence on the impact of introducing improved varieties and will shape our future research

Joint research and development efforts involving CIMMYT, ACIAR, the Food and Agriculture Organization (FAO) of the United Nations, the International Centre of Agricultural Research in Dry Areas (ICARDA), French Cooperation, and Afghanistan’s Ministry of Agriculture, Irrigation and Livestock (MAIL) and Agricultural Research Institute (ARIA) have introduced more than 400 modern, disease-resistant wheat varieties over the last two decades. Nearly 75% of the wheat grown in the areas surveyed for this study comes from these improved varieties.

“New sequencing technologies are increasingly affordable and their cost will continue to fall,” said Dreisigacker. “Expanded use of DNA fingerprinting can easily and accurately identify the wheat cultivars in farmers’ fields, thus helping to target breeding, agronomy, and development efforts for better food security and farmer livelihoods.”

A research paper published in the world’s leading scientific journal, Science Magazine, indicates that using the Happy Seeder agriculture technology to manage rice residue has the potential of generating 6,000-11,500 Indian rupees (about US$85-160) more profits per hectare for the average farmer. The Happy Seeder is a tractor-mounted machine that cuts and lifts rice straw, sows wheat into the soil, and deposits the straw over the sown area as mulch.

The paper “Fields on fire: Alternatives to crop residue burning in India” evaluates the public and private costs and benefits of ten alternate farming practices to manage rice residue, including burn and non-burn options. Happy Seeder-based systems emerge as the most profitable and scalable residue management practice as they are, on average, 10%–20% more profitable than burning. This option also has the largest potential to reduce the environmental footprint of on-farm activities, as it would eliminate air pollution and would reduce greenhouse gas emissions per hectare by more than 78%, relative to all burning options.

This research aims to make the business case for why farmers should adopt no-burn alternative farming practices, discusses barriers to their uptake and solutions to increase their widespread adoption. This work was jointly undertaken by 29 Indian and international researchers from The Nature Conservancy, the International Maize and Wheat Improvement Centre (CIMMYT), the University of Minnesota, the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) and other organizations.

Every year, some 23 million tonnes of rice residue is burnt in the states of Haryana, Punjab and Western Uttar Pradesh, contributing significantly to air pollution and short-lived climate pollutants. In Delhi NCR, about half the air pollution on some winter days can be attributed to agricultural fires, when air quality level is 20 times higher than the safe threshold defined by WHO. Residue burning has enormous impacts on human health, soil health, the economy and climate change.

“Despite its drawbacks, a key reason why burning continues in northwest India is the perception that profitable alternatives do not exist. Our analysis demonstrates that the Happy Seeder is a profitable solution that could be scaled up for adoption among the 2.5 million farmers involved in the rice-wheat cropping cycle in northwest India, thereby completely eliminating the need to burn. It can also lower agriculture’s contribution to India’s greenhouse gas emissions, while adding to the goal of doubling farmers income,” says Priya Shyamsundar, Lead Economist at The Nature Conservancy and one of the lead authors of the paper.

“Better practices can help farmers adapt to warmer winters and extreme, erratic weather events such as droughts and floods, which are having a terrible impact on agriculture and livelihoods. In addition, India’s efforts to transition to more sustainable, less polluting farming practices can provide lessons for other countries facing similar risks and challenges,” explains M.L. Jat, CIMMYT cropping systems specialist and a co-author of the study.

“Within one year of our dedicated action using about US$75 million under the Central Sector Scheme on ‘Promotion of agriculture mechanization for in-situ management of crop residue in the states of Punjab, Haryana, Uttar Pradesh and NCT of Delhi,’ we could reach 0.8 million hectares of adoption of Happy Seeder/zero tillage technology in the northwestern states of India,” said Trilochan Mohapatra, director general of the Indian Council of Agricultural Research (ICAR). “Considering the findings of the Science article as well as reports from thousands of participatory validation trials, our efforts have resulted in an additional direct farmer benefit of US$131 million, compared to a burning option,” explained Mohapatra, who is also secretary of India’s Department of Agricultural Research and Education.

The Government of India subsidy in 2018 for onsite rice residue management has partly addressed a major financial barrier for farmers, which has resulted in an increase in Happy Seeder use. However, other barriers still exist, such as lack of knowledge of profitable no-burn solutions and impacts of burning, uncertainty about new technologies and burning ban implementation, and constraints in the supply-chain and rental markets. The paper states that NGOs, research organizations and universities can support the government in addressing these barriers through farmer communication campaigns, social nudging through trusted networks and demonstration and training. The private sector also has a critical role to play in increasing manufacturing and machinery rentals.

Top scientists from CGIAR to present latest research at International Wheat Congress in Canada

FOR IMMEDIATE RELEASE

SASKATOON, Canada (CIMMYT) — Amid global efforts to intensify the nutritional value and scale of wheat production, scientists from all major wheat growing regions in the world will gather from July 21 to 26, 2019 at the International Wheat Congress in Saskatoon, the city at the heart of Canada’s western wheat growing province, Saskatchewan. The CGIAR Research Program on Wheat (WHEAT), led by the International Maize and Wheat Improvement Center (CIMMYT), is a founding member of the G20 Wheat Initiative, a co-host of the conference.

Wheat provides 20% of all human calories consumed worldwide. In the Global South, it is the main source of protein and a critical source of life for 2.5 billion people who live on less than $2 (C$2.60) a day.

In spite of its key role in combating hunger and malnutrition, the major staple grain faces threats from climate change, variable weather, disease, predators and many other challenges. Wheat’s vital contribution to the human diet and farmer livelihoods makes it central to conversations about the rural environment, agricultural biodiversity and global food security.

More than 800 delegates, including researchers from the CGIAR Research Program on Wheat, CIMMYT, the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Wheat Yield Partnership (IWYP), Cornell University’s Delivering Genetic Gain in Wheat project (DGGW), the University of Saskatchewan and many other organizations worldwide will discuss the latest research on wheat germplasm.

“We must solve a complex puzzle,” said Martin Kropff, CIMMYT’s director general. “Wheat must feed more people while growing sustainably on less land. Wheat demand is predicted to increase 60% in the next three decades, while climate change is putting an unprecedented strain on production.”

“The scientific community is tackling this challenge head-on, through global collaboration, germplasm exchange and innovative approaches. Researchers are looking at wheat’s temperature response mechanisms and using remote sensing, genomics, bio-informatics and other technologies to make wheat more tolerant to heat and drought,” Kropff said.

The congress is the first major gathering of the wheat community since the 2015 International Wheat Conference in Sydney, Australia.

CGIAR and CIMMYT scientists will share the latest findings on:

  • State-of-the-art approaches for measuring traits to speed breeding for heat and drought tolerance
  • Breeding durum (pasta) wheat for traits for use in bread products
  • New sources of diversity — including ancient wheat relatives — to create aphid-resistant wheat and other improved varieties
  • DNA fingerprinting to help national partners identify gaps in improved variety adoption

For more details on schedule and scientists’ presentations, click here.

Research shows that more than 60% of wheat varietal releases since 1994 were CGIAR-related.

Low- and middle-income countries are the primary focus and biggest beneficiaries of CGIAR wheat research, but high-income countries reap substantial rewards as well. In Canada, three-quarters of the wheat area is sown to CGIAR-related cultivars and in the United States almost 60% of the wheat area was sown to CGIAR-related varieties, according to the research.

Groundwater conservation policies help fuel air pollution crisis in northwestern India, new study finds

Groundwater conservation policies are contributing to the air pollution crisis in northwestern India by concentrating agricultural fires into a narrower window when weather conditions favor poor air quality, according to a new study by the International Maize and Wheat Improvement Center (CIMMYT) published on Nature Sustainability.

Facing severe groundwater depletion from intensive crop cultivation, the state governments of Haryana and Punjab introduced separate legislation in 2009 to prohibit early rice establishment in order to reduce water consumption. The study revealed that later rice planting results in later rice harvest, leading to a delayed and condensed period when residues are burned prior to wheat establishment. Consequently, more farmers are setting fire to crop residues at the same time, increasing peak fire intensity by 39%, contributing significantly to atmospheric pollution.

“Despite being illegal, the burning of post-harvest rice residues continues to be the most common practice of crop residue management in northwestern India, and while groundwater policies are helping arrest water depletion, they also appear to be exacerbating one of the most acute public health problems confronting India,” said CIMMYT scientist Balwinder Singh.

“Burning agricultural waste dominantly releases PM2.5 aerosols, a type of fine particulate matter that is particularly harmful to human health,” he explained.

Air pollution in India kills an estimated 1.5 million people every year, with nearly half of these deaths occurring in the Indo-Gangetic Plains, the northernmost part of the country that includes New Delhi.

A holistic view of policies to support sustainable development

The research results shed light on the sustainability challenges confronting many highly productive agricultural systems, where addressing one problem can exacerbate others, said Andrew McDonald, a professor at Cornell University and co-author of the study.

“Identifying and managing tradeoffs and capitalizing on synergies between crop productivity, resource conservation, and environmental quality is essential,” McDonald said.

“To devise more effective agricultural development programs and policies, integrative assessments are required that meld groundwater, air quality, economic, and technology scaling considerations in common frameworks,” he explained.

The current policy environment in India encourages productivity maximization of cereals and very high levels of residue production especially in the western Indo-Gangetic Plains, according to Bruno Gerard, another author of the study and head of CIMMYT’s Sustainable Intensification Program.

“If these policies are changed, companion efforts must facilitate sustainable intensification in areas such as the Eastern Gangetic Plains, where water resources are relatively abundant and closer coupling of crop-livestock systems provides a diverse set of end-uses for crops residues,” Gerard said.

The way forward

Northwestern India is home to millions of smallholder farmers and a global breadbasket for grain staples, accounting for 85% of the wheat procured by the Indian government. Thus, what happens here has regional and global ramifications for food security.

“A sensible approach for overcoming tradeoffs will embrace agronomic technologies such as the Happy Seeder, a seed drill that plants seeds without impacting crop residue, providing farmers the technical means to avoid residue burning,” said ML Jat, a scientist with CIMMYT who coordinates sustainable intensification programs in northwestern India.

“Through continued efforts on the technical refinement and business model development for the Happy Seeder technology, uptake has accelerated,” he added. “Financial incentives in the form of payments for ecosystem services may provide an additional boost to adoption.”

“Additional agronomic management measure such as cultivation of shorter-duration rice varieties may help arrest groundwater decline while reducing the damaging concentration of agricultural burning,” Jat explained.

The researchers suggested that long-term solutions will likely require crop diversification away from rice towards crops that demand less water, like maize, as recently started by the government in the state of Haryana.

STOCKHOLM, Sweden — Millions of families in Africa and South Asia have improved their diet with a special variety of sweet potato designed to tackle vitamin A deficiency, according to a report published today.

A six-year project, launched in 2013, used a double-edged approach of providing farming families with sweet potato cuttings as well as nutritional education on the benefits of orange-fleshed sweet potato.

The Scaling Up Sweetpotato through Agriculture and Nutrition (SUSTAIN) project, led by the International Potato Center (CIP) and more than 20 partners, reached more than 2.3 million households with children under five with planting material.

The project, which was rolled out in Kenya, Malawi, Mozambique and Rwanda as well as Bangladesh and Tanzania, resulted in 1.3 million women and children regularly eating orange-fleshed sweet potato when available.

“Vitamin A deficiency (VAD) is one of the most pernicious forms of undernourishment and can limit growth, weaken immunity, lead to blindness, and increase mortality in children,” said Barbara Wells, director general of CIP. “Globally, 165 million children under five suffer from VAD, mostly in Africa and Asia.”

“The results of the SUSTAIN project show that agriculture and nutrition interventions can reinforce each other to inspire behavior change towards healthier diets in smallholder households.”

Over the past decade, CIP and partners have developed dozens of biofortified varieties of orange-fleshed sweet potato in Africa and Asia. These varieties contain high levels of beta-carotene, which the body converts into vitamin A.

Just 125g of fresh orange-fleshed sweet potato provides the daily vitamin A needs of a pre-school child, as well as providing high levels of vitamins B6 and C, manganese and potassium.

Under the SUSTAIN project, families in target communities received nutritional education at rural health centers as well as cuttings that they could then plant and grow.

For every household directly reached with planting material, an additional 4.2 households were reached on average through farmer-to-farmer interactions or partner activities using technologies or materials developed by SUSTAIN.

The project also promoted commercial opportunities for smallholder farmers with annual sales of orange-fleshed sweet potato puree-based products estimated at more than $890,000 as a result of the project.

Perspectives from the Global South

The results of the initiative were published during the EAT Forum in Stockholm, where CGIAR scientists discussed the recommendations of the EAT-Lancet report from the perspective of developing countries.

“The SUSTAIN project showed the enormous potential for achieving both healthy and sustainable diets in developing countries using improved varieties of crops that are already widely grown,” said Simon Heck, program leader, CIP.

“Sweet potato should be included as the basis for a sustainable diet in many developing countries because it provides more calories per hectare and per growing month than all the major grain crops, while tackling a major nutrition-related health issue.”

At an EAT Forum side event, scientists highlighted that most food is grown by small-scale producers in low- and middle-income countries, where hunger and undernutrition are prevalent and where some of the largest opportunities exist for food system and dietary transformation.

“There are almost 500 million small farms that comprise close to half the world’s farmland and are home to many of the world’s most vulnerable populations,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT).

“Without access to appropriate technologies and support to sustainably intensify production, small farmers — the backbone of our global food system — will not be able to actively contribute a global food transformation.”

Matthew Morell, director general of the International Rice Research Institute (IRRI), added: “If the EAT-Lancet planetary health diet guidelines are to be truly global, they will need to be adapted to developing-world realities — such as addressing Vitamin A deficiency through bio-fortification of a range of staple crops.

“This creative approach is a strong example of how to address a devastating and persistent nutrition gap in South Asia and Africa.”

Biofortified maize and wheat can improve diets and health, new study shows

TEXCOCO, Mexico (CIMMYT) — More nutritious crop varieties developed and spread through a unique global science partnership are offering enhanced nutrition for hundreds of millions of people whose diets depend heavily on staple crops such as maize and wheat, according to a new study in the science journal Cereal Foods World.

From work begun in the late 1990s and supported by numerous national research organizations and scaling partners, more than 60 maize and wheat varieties whose grain features enhanced levels of zinc or provitamin A have been released to farmers and consumers in 19 countries of Africa, Asia, and Latin America over the last 7 years. All were developed using conventional cross-breeding.

Farmer and consumer interest has grown for some 60 maize and wheat varieties whose grain features enhanced levels of the essential micronutrients zinc and provitamin A, developed and promoted through collaborations of CIMMYT, HarvestPlus, and partners in 19 countries (Map: Sam Storr/CIMMYT).

“The varieties are spreading among smallholder farmers and households in areas where diets often lack these essential micronutrients, because people cannot afford diverse foods and depend heavily on dishes made from staple crops,” said Natalia Palacios, maize nutrition quality specialist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the study.

More than 2 billion people worldwide suffer from “hidden hunger,” wherein they fail to obtain enough of such micronutrients from the foods they eat and suffer serious ailments including poor vision, vomiting, and diarrhea, especially in children, according to Wolfgang Pfeiffer, co-author of the study and head of research, development, delivery, and commercialization of biofortified crops at the CGIAR program known as “HarvestPlus.”

“Biofortification — the development of micronutrient-dense staple crops using traditional breeding and modern biotechnology — is a promising approach to improve nutrition, as part of an integrated, food systems strategy,” said Pfeiffer, noting that HarvestPlus, CIMMYT, and the International Institute of Tropical Agriculture (IITA) are catalyzing the creation and global spread of biofortified maize and wheat.

“Eating provitamin A maize has been shown to be as effective as taking Vitamin A supplements,” he explained, “and a 2018 study in India found that using zinc-biofortified wheat to prepare traditional foods can significantly improve children’s health.”

Six biofortified wheat varieties released in India and Pakistan feature grain with 6–12 parts per million more zinc than is found traditional wheat, as well as drought tolerance and resistance to locally important wheat diseases, said Velu Govindan, a breeder who leads CIMMYT’s work on biofortified wheat and co-authored the study.

“Through dozens of public–private partnerships and farmer participatory trials, we’re testing and promoting high-zinc wheat varieties in Afghanistan, Ethiopia, Nepal, Rwanda, and Zimbabwe,” Govindan said. “CIMMYT is also seeking funding to make high-zinc grain a core trait in all its breeding lines.”

Pfeiffer said that partners in this effort are promoting the full integration of biofortified maize and wheat varieties into research, policy, and food value chains. “Communications and raising awareness about biofortified crops are key to our work.”

LUSAKA, Zambia (CIMMYT) – The CGIAR Research Program on Maize (MAIZE) officially announced the winners of the 2019 MAIZE Youth Innovators Awards – Africa at an awards ceremony held on May 9, 2019, in Lusaka, Zambia. These awards recognize the contributions of young women and men under 35 to innovation in African maize-based agri-food systems, including research for development, seed systems, agribusiness, and sustainable intensification. The awards, an initiative of MAIZE in collaboration with Young Professionals for Agricultural Research and Development (YPARD), were offered in three categories: farmer, change agent, and researcher.

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. This is the second year of the award, which was launched in 2018 with a first cohort of winners from Asia. Part of the vision is to create a global network of young innovators in maize based systems from around the world.

2019 award recipients were invited to attend the Stress Tolerant Maize for Africa (STMA) project meeting in Lusaka, May 7-9, where they had the opportunity to present their work. The project meeting and award ceremony also allowed these young innovators to network and exchange experiences with MAIZE researchers and partners. Looking forward, award recipients may also get the opportunity to collaborate with MAIZE and its partner scientists in Africa on implementing or furthering their innovations.

This year’s five awardees are:

Hildegarde Dukunde (Rwanda) – Category: Change Agent

Dukunde is a graduate in Human Nutrition and serves as a Sales Associate for Agrifood Business Consulting Ltd. She has been at the forefront of preventing aflatoxin contamination in Rwanda by helping smallholder farmers to access low-cost post-harvest equipment, namely DryCard™ and Purdue Improved Crop Storage (PICS) bags. The DryCard™ is an inexpensive device developed by University of California Davis researchers for determining if dried food is dry enough to prevent mold growth and aflatoxin contamination during storage and reducing post-harvest losses.

Mila Lokwa Giresse (Democratic Republic of the Congo) – Category: Change Agent

Giresse is the CEO of Mobile Agribiz. This company develops the Mobile Agribiz App, an innovative tool to enhance the pest and disease diagnostics of fall armyworm in maize. It uses artificial intelligence and machine learning to easily detect the pest across maize crops at any stage of the production cycle. The app aims to assist farmers, extension workers, and agribusinesses in democratic republic of Congo with early detection and accurate diagnosis. Through SMS and smart alert notifications, the Mobile Agribiz App provides farmers with constant reminders and real-time information on how to detect, manage, and address fall armyworm on maize.

Blessings Likagwa (Malawi) – Category: Farmer

Likagwa lives in Mtunthama, Malawi, where he works on his family’s farm. From a young age he has had an interest in farming and for the past eight years he has been involved in growing a variety of crops, especially maize and cassava. In the future he hopes to use his bachelor’s degree in Community Development and his interest in technology to help smallholder farmers in Malawi and Eastern Africa adapt to the challenges of climate change and rapid population growth. Since 2018, in collaboration with UNICEF and Kyoto University, he has investigated how drone technology can improve agricultural performance and benefit Malawi’s smallholders.

Ismael Mayanja (Uganda) – Category: Researcher

Mayanja is a 2019 graduate of Makerere University with a Bachelor of Science degree in Agricultural Engineering. He is currently assisting research at Makerere University to ascertain and quantify post-harvest losses associated with transportation of agricultural produce in the markets of Kampala district, Uganda. His primary research interest lies in post-harvest handling and technology, motivated by the reported 40% post-harvest loss of agricultural produce by farmers in sub-Saharan Africa. He developed a bicycle-powered maize cleaning machine to increase efficiency and reduce time dedicated to cleaning maize at several primary schools in Uganda.

Admire Shayanowako (Republic of South Africa) – Category: Researcher

Shayanowako is a researcher at the African Centre for Crop Improvement (ACCI) – University KwaZulu-Natal. His research focuses on the parasitic weed Striga, also known as witch weed, which causes severe crop losses to millions of small-scale African maize farmers. The goal of the project is to combine breeding for Striga resistance in maize with a soil fungus, Fusarium oxysporum f.sp. strigae (FOS) that is highly specific in its pathogenicity to Striga and acts as a biological control agent. The breeding approach aims to develop at least partial host resistance in open pollinated maize germplasms that are adapted to the semi-arid regions. When partial host resistance is augmented with biological control agent FOS, parasitic effects of Striga decline overwhelmingly. Currently, the breeding component of the research has embarked on identification of quantitative trait locus (QTL) controlling Striga resistance in maize through genomic based approaches.
