As a fast growing region with increasing challenges for smallholder farmers, Asia is a key target region for CIMMYT. CIMMYT’s work stretches from Central Asia to southern China and incorporates system-wide approaches to improve wheat and maize productivity and deliver quality seed to areas with high rates of child malnutrition. Activities involve national and regional local organizations to facilitate greater adoption of new technologies by farmers and benefit from close partnerships with farmer associations and agricultural extension agents.

ANKARA, Turkey (CIMMYT) – In a world of rapidly changing climates and related threats to agriculture and food production, including the emergence and spread of deadly crop pathogens and pests, Turkey’s Ministry of Food, Agriculture and Livestock (MFAL) has for the first time allocated funding to establish a world-class center for research on soil borne pathogens.
The announcement was made at an international workshop on soil borne pathogens (SBP) organized at MFAL in Ankara in October by the Directorate of Turkey’s Plant Protection Central Research Institute, Ankara (PPCRI). The new SBP research center will be located at that PPCRI, according to Dr. Nevzat BİRİŞİK, Director General, MFAL General Directorate of Agricultural Research and Policies.
“Among other things, the new center will focus on controlling the expansion of soil borne pathogens to new cropping areas, as well as linking to international research and experts on the pathogens, which cause massive damage each year to agriculture in Turkey,” BİRİŞİK said.
More than 147 delegates from across the ministry of agriculture and representatives of private companies gathered at this workshop, bringing together senior government officials and high-level experts to review and discuss scientific and technical activities in the management of soil borne pathogens in cereals.
The Turkish Ministry of Agriculture has given ongoing support to the International Maize and Wheat Improvement Center (CIMMYT)-led SBP program in Turkey to fight against diseases affecting cereal crops, which occupy 65 percent of Turkey’s farmland.

Soil borne pathogens cause significant damage in cereals, with global yield potential losses in wheat of up to 20 percent. Changing climates that are reducing growing conditions in tropical areas are also enabling the spread of SBPs into northern regions at increasing rates. This spread presents the risk of areas previously unaffected by SBPs having serious issues. Climate change may also affect the resistance of crops to specific soil pathogens through impacts of warming or drought and through the increased pathogenicity of organisms by mutation induced by environmental stress.
The SBP program is also involved with the use of chemical control on soil pathogens, with regard to the outlook and future expectations of pioneering pesticide producers in the world. The SBP program at CIMMYT-Turkey is using seed treatment to investigate whether or not it can synergistically reduce diseases populations. Seed treatment is absolutely required where diseases are present or where farmers do not accept changing their local, highly susceptible varieties with the resistant and modern ones.

EL BATAN, Mexico (CIMMYT) — In conjunction with recent state regulations outlawing the use of fire to destroy field crop waste in northwest India, some farmers are benefitting from technological innovations that can help prevent damaging smog levels in the capital Delhi and other areas, according to scientists.
Currently, the majority of farmers in northwest India burn leftover vegetation residue to prepare fields for planting in cyclical rice-wheat crop rotations, leading to negative consequences for soil quality, the environment, animal and human health. Rice-wheat crop rotations make up 84 percent of burned crops, a key source of atmospheric pollution.
“Farmers need access to appropriate machinery and training to implement change to discourage burning,” said M.L. Jat, a systems agronomist who works in New Delhi with the International Maize and Wheat Improvement Center (CIMMYT). “Using crop residue in a sustainable and eco-friendly manner could benefit all stakeholders.”
Many farmers keep costs low by burning residue on the farm, rather than paying for its removal for other uses, which could include animal feed, biofuel, incorporating it into the soil or retaining it in the field as mulch, according to a research paper titled “Burning issues of paddy residue management in northwest fields of India.” Fire is also used to eliminate weeds, pests, disease and remaining field stubble after harvest.
Ash left on the fields after residue burning increases the availability of some nutrients, while depleting others and negatively affecting soil health in the long term. During burning, soil temperature increases, bacteria and fungi are killed off, regenerating in a matter of days. Residue burning can damage plants and trees on field edges with negative implications for the overall ecosystem.
Residues can be used as a renewable energy source to improve air, soil quality, climate change and reduce global warming, provided these are economically viable options for farmers. Incentives could also help encourage farmers to leave residues on their fields for use as fertilizer.
If residue is mulched into the soil, nutrient levels improve and carbon sequestration capacity increases, lowering the release of greenhouse gases into the environment. Additionally, residue retention reduces evaporation and increases soil moisture by as much as 10 percent during the wheat-growing season.
Farmers can benefit from the Happy Seeder, a machine that can plant wheat seed directly into the soil by boring through crop residue. The Straw Management System (SMS) machine spreads straw residue thinly on the soil surface allowing seeding.
“Residues are also of great economic value as livestock feed, fuel and industrial raw materials, but of the total rice residues produced in northwestern India, only around 15 percent can potentially be used for these purposes and the rest must be managed with in-situ (on site) management technologies,” said Jat, who conducted the research in collaboration with the CGIAR research programs on maize (CRP Maize), wheat (CRP Wheat) and climate change, agriculture and food security (CCAFS).
“Although farmers are aware of the adverse affects of crop burning, they rely on it due to the lack of economically viable and acceptable machinery and alternatives to dispose of residue.”
However, deploying advanced technology, including the concurrent use of straw management systems, fitted combine harvesters and Happy Seeders for direct drilling is a viable solution to eliminate burning, he added.
With these advancements and aggressive campaigns, within a period of a couple of months in Punjab state alone, over 1,000 combine owners have launched a “Super SMS.”
Additionally, nearly 2,000 happy seeders are being manufactured, which will lead to large-scale adoption of conservation agriculture techniques in the upcoming wheat season, Jat said.
Index insurance is one of the top 10 innovations for climate-proof farming. Photo: P. Lowe/ CIMMYT
What stands between a smallholder farmer and a bag of climate-adapted seeds? In many cases, it’s the hesitation to take a risk. Farmers may want to use improved varieties, invest in new tools, or diversify what they grow, but they need reassurance that their investments and hard work will not be squandered.
Climate change already threatens crops and livestock; one unfortunately-timed dry spell or flash flood can mean losing everything. Today, innovative insurance products are tipping the balance in farmers’ favor. That’s why insurance is featured as one of 10 innovations for climate action in agriculture, in a new report released ahead of next week’s UN Climate Talks. These innovations are drawn from decades of agricultural research for development by CGIAR and its partners and showcase an array of integrated solutions that can transform the food system.
Index insurance is making a difference to farmers at the frontlines of climate change. It is an essential building block for adapting our global food system and helping farmers thrive in a changing climate. Taken together with other innovations like stress-tolerant crop varieties, climate-informed advisories for farmers, and creative business and financial models, index insurance shows tremendous promise.
The concept is simple. To start with, farmers who are covered can recoup their losses if (for example) rainfall or average yield falls above or below a pre-specified threshold or ‘index’. This is a leap forward compared to the costly and slow process of manually verifying the damage and loss in each farmer’s field. In India, scientists from the International Water Management Institute (IWMI) and the Indian Council of Agricultural Research (ICAR), have worked out the water level thresholds that could spell disaster for rice farmers if exceeded. Combining 35 years of observed rainfall and other data, with high-resolution satellite images of actual flooding, scientists and insurers can accurately gauge the extent of flooding and crop loss to quickly determine who gets payouts.
The core feature of index insurance is to offer a lifeline to farmers, so they can shield themselves from the very worst effects of climate change. But that’s not all. Together with my team, we’re investigating how insurance can help farmers adopt new and improved varieties. Scientists are very good at developing technologies but farmers are not always willing to make the leap. This is one of the most important challenges that we grapple with. What we’ve found has amazed us: buying insurance can help farmers overcome uncertainty and give them the confidence to invest in new innovations and approaches. This is critical for climate change adaptation. We’re also finding that creditors are more willing to lend to insured farmers and that insurance can stimulate entrepreneurship and innovation. Ultimately, insurance can help break poverty traps, by encouraging a transformation in farming.
Insurers at the cutting edge are making it easy for farmers to get coverage. In Kenya, insurance is being bundled into bags of maize seeds, in a scheme led by ACRE Africa. Farmers pay a small premium when buying the seeds and each bag contains a scratch card with a code, which farmers text to ACRE at the time of planting. This initiates coverage against drought for the next 21 days; participating farms are monitored using satellite imagery. If there are enough days without rain, a farmer gets paid instantly via their mobile phone.

Farmers everywhere are businesspeople who seek to increase yields and profits while minimizing risk and losses. As such, insurance has widespread appeal. We’ve seen successful initiatives grow rapidly in India, China, Zambia, Kenya and Mexico, which points to significant potential in other countries and contexts. The farmers most likely to benefit from index insurance are emergent and commercial farmers, as they are more likely than subsistence smallholder farmers to purchase insurance on a continual basis.
It’s time for more investment in index insurance and other innovations that can help farmers adapt to climate change. Countries have overwhelmingly prioritized climate actions in the agriculture sector, and sustained support is now needed to help them meet the goals set out in the Paris Climate Agreement.

India needs to tackle greenhouse gas emissions from its rice and livestock sectors according to a study by CIMMYT and partners. Researchers say this can and must be done in ways that improve yields, and sustain food and nutrition security.
Paradoxically, India is also the world’s second largest food producer, and agriculture is a vital part of the country’s economy. Indian agriculture also accounts for about 18% of the country’s greenhouse gas emissions, making agriculture a key sector for climate action. In fact, India’s government has already indicated willingness to reduce emissions from agriculture as part the Paris Climate Agreement, in an effort to keep global warming below the 2-degree target. To take action, the country’s leaders need to know where to focus their efforts, and find ways to reduce emissions without compromising food and nutrition security.
Indian agriculture’s climate ‘hotspots’
A new study uncovers some answers to this question, and offers insights into how dietary shifts might influence future emissions. The study, Greenhouse gas emissions from agricultural food production to supply Indian diets: Implications for climate change mitigation, was done by researchers from the International Maize and Wheat Improvement Center (CIMMYT) and partners at the University of Aberdeen and the London School of Hygiene & Tropical Medicine. Using the empirical model Cool Farm Tool, researchers analyzed the farm-level greenhouse gas emissions of 20 major food commodities in India, and two types of food products emerged as the worst culprits: rice and animal products such as meat, milk and eggs.
When looking at the level of emission per unit of area and unit of product, rice was the top source of emissions in agriculture. Continuously flooded paddies release huge amounts of methane, especially compared to intermittently flooded or irrigated rice land. The scientists found that the total global warming potential of rice on a per hectare basis was even higher than what was being reported in existing literature and at the national level.
Meat, eggs and milk were also found to have high emissions per unit of production. The authors warn that animal products will contribute an increasing share to overall emissions as India’s middle class grows, traditions evolve, and diets shift towards consumption of more animal products. That said, it will probably not match the rapid trajectory towards meat consumption of other large countries like China, due to India’s cultural preference for a lacto-ovo-vegetarian diet.
No tradeoff between mitigation and food security
The revelation of India’s agricultural emission ‘hotspots’ are a crucial step towards action. “These findings can help farmers, researchers and policy makers to understand and manage these emissions, and identify mitigation responses that are consistent with India’s food security and economic development priorities,” according to CIMMYT scientist Tek Sapkota, who co-authored the paper. “Agriculture is an important sector of the economy,” he said. “If India is to reduce its total emissions then agriculture has to play its part,” he explained, mentioning that emissions from agriculture must decline worldwide in order to meet the 2°C warming target.
In the UN climate discussions on agriculture, there has been ongoing resistance among some countries about promoting mitigation in agriculture, due to fears that this could compromise food security and nutrition. This is a “misconception” according to Dr. Sapkota. “Many agricultural practices advocated to increase production and increase the capacity of a system to cope with climate change also happen to reduce emissions,” he explained. The paper’s authors emphasize that mitigation must be a co-benefit of improved and more efficient agronomic practices, and interventions will need to consider the nutritional and health implications. Negotiators at the upcoming UN climate talks in Bonn should take note as they mull a decision on agriculture.
Sustainable solutions
There are many approaches and technologies in agriculture that can contribute to food and nutrition security and at the same time deliver climate change adaptation and mitigation services. Dr. Sapkota is part of a team undertaking a detailed analysis of mitigation options, their national level mitigation potential and associated cost of their adoption to come up with total technical mitigation potential sector of Indian agriculture. This study is coming out very soon, and will help build a more complete picture of the solutions available.

As an example, Dr. Sapkota points to conservation agriculture, which is based on the principles of minimum soil disturbance, continuous soil cover and diversified crop rotation. Conservation agriculture techniques can increase production in a sustainable way, by improving water use efficiency, reducing fertilizer consumption and reducing machinery use and fuel consumption. Through this approach, “you can reduce production costs, without compromising yield. In some instances you can increase yields. It’s a win-win from every perspective,” he says. Farmers are already getting more precise at managing nutrients, using several tools like the GreenSeeker and the , and techniques such as drilling fertilizer into the soil instead of broadcasting it. They are also using decision support systems like Nutrient expert and the Crop Manager, to help them determine how much fertilizer to apply, at the right time and in the right place. These approaches have been shown to reduce the amount of fertilizer needed while maintaining and even increasing yields.
In a similar vein, Alternative Wetting and Drying of rice fields, which otherwise remain continuously flooded, can reduce methane emissions substantially. In Vietnam and the Philippines, farmers have successfully used this method and reduced methane emissions by 48% without reducing yield.
In the livestock sector, there several ways to address emissions, including improved manure management, changing feed rations, growing feed crops in a more sustainable way, and feeding animals crop residues that would otherwise be burned.
Although the study points out food products with a particularly high climate footprint, it’s important not to think about solutions on a commodity-by-commodity or crop-by-crop basis, according to Dr. Sapkota. “Farmers grow crops in a system and we need system-based solutions,” he says. “For example, in the rice-wheat system in Indo-Gangetic Plains, if you want to go for conservation agriculture you cannot just focus on one crop. The way you manage water, energy,nutrients and other resources for one crop will have repercussions on other crops,” he explains.
The results of this study are an important starting point. “India is moving in the right direction,” says Dr. Sapkota. “Now there needs to be more research to show the effectiveness of technical mitigation options which can reduce emissions without compromising yield and profit,” he says. The government must also work closely with people on the ground: “There must be more awareness among extension workers and farming communities that they are part of this movement to tackle climate change,” he adds.

SAMBALI, India (CIMMYT) – In the 1960s, India became the center of the Green Revolution by adopting high-yielding crop varieties and new technologies and practices that staved off famine for millions.
Today, India needs a new Green Revolution.
The country’s combination of high greenhouse gas emissions, vulnerability to climate change and pressure to feed nearly 2 billion people by 2050 is driving farmers to find ways to grow more food in harsher environments.
Climate-smart agriculture is a new approach to farming that combines adaptation options that sustainably increase productivity, enhance resilience to climatic stresses and reduce greenhouse gas emissions. This option is becoming increasingly popular among smallholder farmers, who make up nearly 80 percent of India’s farmers and produce more than 40 percent of its food.
Harynana is a north-western state in India, and part of the Indo-Gangetic Plain, which covers an area of over 2.5 million square kilometers and feeds 500 million people. The village of Sambali, in Haryana, is one of the first communities in India to officially become “climate-smart” as part of the CGIAR Research Program on Climate Change, Agriculture and Food Security project (CCAFS), which is helping smallholder farmers globally find practical adaptation options to improve food security and resilience to climate change effects like drought, flooding and other extreme weather events.
In Sambali, more than 60 percent of the population depends on agriculture for their livelihoods. For over 50 years, farmers from the village have worked with Indian Council of Agricultural Research-Central Soil Salinity Research Institute (ICAR-CSSRI), this long-term knowledge exchange and exposure has resulted in 45 percent of the farming community practicing climate smart farming.
However, residue burning – the burning of excess residue on fields after a crop is harvested, as a means to clear the area to plant the next crop – remains a common practice in highly cultivated regions in India. Sambali becoming a residue-burning free village is setting an example of a model village contributing towards a healthier environment.
Besides triggering costly respiratory ailments in humans and animals in farm regions and urban centers, burning rice residues has negative agricultural implications. For example, residue burning depletes soil nutrients, with estimated yearly losses in Punjab alone of 3.9 million tons of organic carbon, 59,000 tons of nitrogen, 20,000 tons of phosphorus and 34,000 tons of potassium, according to M.L. Jat, a principal scientist at the International Maize and Wheat Improvement Center (CIMMYT), who leads CIMMYT’s contributions to CCAFS’ climate-smart villages in South Asia.
In response, a CIMMYT-CCAFS campaign was recently organized in Sambali to eliminate residue burning and combat its harmful effects to the environment, soil and human health.
It is advisable to have one percent organic matter in soil to assist conservation and increase productivity. According to Sunil Mann, the State Development Officer of the Department of Agriculture in Haryana, there has been a decline in organic matter in this region due to burning from one percent to less than half of one percent, highlighting a significant threat to soil health and productivity. The challenges of burning are exacerbated by the risk of areas turning into ‘dark zones,’ areas where groundwater has been over-exploited, due to the declining water table.
Hanuman Sahay Jat, a Scientist at CIMMYT, expressed concerns about the amount of chemicals released while burning crop residue and emphasized the need to stop this practice and adopt residue and nutrient management strategies. One way to achieve this is by using technologies like the GreenSeeker, a compact sensor that quickly assesses crop vigor and calculates optimal fertilizer dosages, to reduce dependency on chemical fertilizers and improve soil health.

M.L. Jat also highlighted the need for all stakeholders to do cost-benefit analyses before adopting new technologies. Farmers should ensure that profits will be worth investments in new technologies and researchers should ensure the efficiency and environmental impact of new technologies. For example in Basmati rice growing areas, zero-till machines, which help farmers plant new seeds directly in the residue of their previous crop’s harvest, are half the cost of the traditionally used “turbo happy seeder,” saving farmers money.
A positive result from Sambali will gain political attention and is likely to contribute to the development of new policies favoring climate-smart agriculture and their efficient utilization.
A “Climate Smart Van” was also launched during the campaign, which will drive through villages to spread knowledge, garner support and clarify the aspects of climate smart agriculture.
Sambali and other villages are taking steps towards integrated farming, with stakeholders’ engagement focusing sustainable development and scaling climate-smart agriculture practices while including women in decision making and engaging youth with profit-making opportunities.

KATHMANDU, Nepal (CIMMYT) — Nepal will benefit from a new project that will strengthen the country’s seed and fertilizer sectors, boost farmer income and increase the country’s food security through 2021.
More than 70 percent of Nepal’s population works in agriculture, yet a profound lack of resources, infrastructure and networks have weakened rural economies, increased urban and international migration and strained the ability of families to avoid malnutrition. Two out of every three Nepalese suffer from food insecurity at some time during the year and the prevalence of stunting is nearly 40 percent.
“With right seeds, resources and practices Nepalese farmers could produce 50 percent more food on their land, enough to not only eliminate domestic food insecurity but even become a food surplus country,” said Dyutiman Choudhary, coordinator and market development specialist for the five-year Nepal Seed and Fertilizer project (NSAF).
Research has shown the better application of fertilizer and planting improved hybrid seeds are the two most impactful steps Nepalese maize farmers can take to boost income and grain yields in their fields. Adopting just these two practices can increase grain yields 1.8 and 1.4 tons per hectare, respectively.
Launched on August 1, NSAF will build competitive and vibrant seed and fertilizer systems that significantly expand seed production, marketing and distribution by enhancing the capacity and role of public, private and community sectors in seed and fertilizer value chains. It is funded by the United States Agency for International Development (USAID) and led by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with the Ministry of Agricultural Development (MOAD) and private sector.
During an event for the project’s launch in Kathmandu, Choudhary presented an overview of the project’s overarching strategy and key approaches being implemented to increase adoption of quality seed and integrated soil fertility management technologies for more than 100,000 smallholder farmers in 25 of Nepal’s 75 districts.
MOAD Secretary and Program Chair Suroj Pokharel and Deputy Chief of Mission to the United States Embassy in Nepal Michael C. Gonzales also acknowledged the contribution of robust agriculture projects that support the Government of Nepal’s Agriculture Development Strategy through the promotion of innovations in digital technology and market research development to improve farming practices. Other event invitees included government representatives, the U.S Embassy, USAID, partner organizations, local media, project beneficiaries and other private stakeholders.

DHAKA, Bangladesh (CIMMYT) — As wheat farmers in Bangladesh struggle to recover from a 2016 outbreak of a mysterious disease called “wheat blast,” the country’s National Seed Board (NSB) released a new, high-yielding, blast-resistant wheat variety, according to a communication from the Wheat Research Centre (WRC) in Bangladesh.
Called “BARI Gom 33,” the variety was developed by WRC using a breeding line from the International Maize and Wheat Improvement Center (CIMMYT), a Mexico-based organization that has collaborated with Bangladeshi research organizations for decades, according to Naresh C. Deb Barma, Director of WRC, who said the variety had passed extensive field and laboratory testing. “Gom” means “wheat grain” in Bangla, the Bengali language used in Bangladesh.
“This represents an incredibly rapid response to blast, which struck in a surprise outbreak on 15,000 hectares of wheat in southwestern Bangladesh just last year, devastating the crop and greatly affecting farmers’ food security and livelihoods, not to mention their confidence in sowing wheat,” Barma said.
Caused by the fungus Magnaporthe oryzae pathotype triticum, wheat blast was first identified in Brazil in 1985 and has constrained wheat farming in South America for decades. Little is known about the genetics or interactions of the fungus with wheat or other hosts. Few resistant varieties have been released in Brazil, Bolivia and Paraguay, the countries most affected by wheat blast.
The Bangladesh outbreak was its first appearance in South Asia, a region where rice-wheat cropping rotations cover 13 million hectares and over a billion inhabitants eat wheat as main staple.
Many blast fungal strains are impervious to fungicides, according to Pawan Singh, a CIMMYT wheat pathologist. “The Bangladesh variant is still sensitive to fungicides, but this may not last forever, so we’re rushing to develop and spread new, blast-resistant wheat varieties for South Asia,” Singh explained.
The urgent global response to blast received a big boost in June from the Australian Centre for International Agricultural Research (ACIAR), which funded an initial four-year research project to breed blast resistant wheat varieties and the Indian Council of Agricultural Research (ICAR), which also provided grant to kick-start the work in South Asia. Led by CIMMYT, the initiative involves researchers from nearly a dozen institutions worldwide.
Chemical controls are costly and potentially harmful to human and environmental health, so protecting crops like wheat with inherent resistance is the smart alternative, but resistance must be genetically complex, combining several genes, to withstand new mutations of the pathogen over time.
Key partners in the new project are the agricultural research organizations of Bangladesh, including the Bangladesh Agricultural Research Institute (BARI), and the Instituto Nacional de Innovación Agropecuaria y Forestal in Bolivia, which will assist with large-scale field experiments to select wheat lines under artificial and natural infections of wheat blast.
Other partners include national and provincial research organizations in India, Nepal and Pakistan, as well as Kansas State University (KSU) and the U.S. Department of Agriculture-Agricultural Research Services (USDA-ARS). The U.S. Agency for International Agricultural Development (USAID) has also supported efforts to kick-start blast control measures, partnerships and upscaling the breeding, testing and seed multiplication of new, high-yielding, disease resistant varieties through its Feed the Future project.
BARI Gom 33 was tested for resistance to wheat blast in field trials in Bolivia and Bangladesh and in greenhouse tests by the USDA-ARS laboratory at Fort Detrick, Maryland. International partnerships are critical for a fast response to wheat blast, according to Hans-Joachim Braun, director of CIMMYT’s Global Wheat Program.
“Worldwide, we’re in the middle of efforts that include blast surveillance and forecasting, studies on the pathogen’s genetics and biology, integrated disease management and seed systems, as well as raising awareness about the disease and training for researchers, extension workers, and farmers,” said Braun.
With over 160 million people, Bangladesh is among the world’s most densely populated countries. Wheat is Bangladesh’s second most important staple food, after rice. The country grows more than 1.3 million tons each year but consumes 4.5 million tons, meaning that imports whose costs exceed $0.7 billion each year comprise more than two-thirds of domestic wheat grain use.
WRC will produce tons of breeder’s seed of BARI Gom 33 each year. This will be used by the Bangladesh Agricultural Development Corporation (BADC) and diverse non-governmental organizations and private companies to produce certified seed for farmers.
“This year WRC will provide seed to BADC for multiplication and the Department of Agricultural Extension will establish on-farm demonstrations of the new variety in blast prone districts during 2017-18,” said Barma.
As an added benefit for the nutrition of wheat consuming households, BARI Gom 33 grain features 30 percent higher levels of zinc than conventional wheat. Zinc is a critical micronutrient missing in the diets of many of the poor throughout South Asia and whose lack particularly harms the health of pregnant women and children under 5 years old.
With funding from HarvestPlus and the CGIAR Research Program on Agriculture for Nutrition, CIMMYT is leading global efforts to breed biofortified wheat with better agronomic and nutritional quality traits. The wheat line used in BARI Gom 33 was developed at CIMMYT, Mexico, through traditional cross-breeding and shared with Bangladesh and other cooperators in South Asia through the Center’s International Wheat Improvement Network, which celebrates 50 years in 2018.
Stable window 1 and 2 (W1W2) funding from CGIAR enabled CIMMYT and partners to react quickly and screen breeding lines in Bolivia, as well as working with KSU to identify sources of wheat blast resistance. The following W1 funders have made wheat blast resistance breeding possible: Australia, the Bill & Melinda Gates Foundation, Canada, France, India, Japan, Korea, New Zeland, Norway, Sweden, Switzerland, the United Kingdom and the World Bank. The following funders also contributed vital W2 funding: Australia, China, the United Kingdom (DFID) and USAID.

EL BATAN, Mexico (CIMMYT) — New research shows improved wheat raises the quality of life for men and women across rural communities in Afghanistan.
A recent report from Gennovate, a major study about gender and innovation processes in developing country agriculture, found that improved wheat varieties emerged overwhelmingly among the agricultural technologies most favored by both men and women.
In one striking example from Afghanistan, introducing better wheat varieties alone reduced women’s work burden, showing how the uptake of technology – whether seeds or machinery – can improve the quality of life.
“Local varieties are tall and prone to falling, difficult to thresh, and more susceptible to diseases, including smuts and bunts, which requires special cleaning measures, a task normally done by women,” said Rajiv Sharma, a senior wheat scientist at the International Maize and Wheat Improvement Center (CIMMYT) and country liaison officer for CIMMYT in Afghanistan. “Such varieties may comprise mixes of several seed types, including seed of weeds. They also give small harvests for which threshing is typically manual, with wooden rollers and animals, picking up sticks, stones, and even animal excrement that greatly complicates cleaning the grain.”
Both women and men spoke favorably about how improved wheat varieties have eased women’s wheat cleaning work. “Improved seeds can provide clean wheat,” said an 18-year old woman from one of the study’s youth focus groups in Panali, Afghanistan. “Before, we were washing wheat grains and we exposed it to the sun until it dried. Machineries have [also] eased women’s tasks.”
Finally, Sharma noted that bountiful harvests from improved varieties often lead farmers to use mechanical threshing, which further reduces work and ensures cleaner grain for household foods.
Gennovate: A large-scale, qualitative, comparative snapshot
Conceived as a “bottom-up” idea by a small gender research team of CGIAR in 2013, Gennovate involves 11 past and current CGIAR Research Programs. The project collected data from focus groups and interviews involving more than 7,500 rural men and women in 26 countries during 2014-16.
According to estimates of the Food and Agriculture Organization of the United Nations (FAO), if women farmers had the same access to resources as men, agricultural output in developing countries would rise by an estimated average of as high as 4 percent. Photo: CIMMYT archives
Some 2,500 women and men from 43 rural villages in 8 wheat-producing countries of Africa and Asia participated in community case studies, as part of the CGIAR Research Program on Wheat.
“Across wheat farm settings, both men and women reported a sense of gradual progress,” said Lone Badstue, gender specialist at CIMMYT and Gennovate project leader. “But women still face huge challenges to access information and resources or have a voice in decision making, even about their own lives.”
According to estimates of the Food and Agriculture Organization of the United Nations (FAO), if women farmers, who comprise 43 per cent of the farm labor force in developing countries, had the same access to resources as men, agricultural output in 34 developing countries would rise by an estimated average of as high as 4 percent.
“Gender-related restrictions such as limitations on physical mobility or social interactions, as well as reproductive work burden, also constitute key constraints on rural women’s capacity to innovate in agriculture,” Badstue explained.
Gender equity drives innovation
The Gennovate-wheat report identified six “positive outlier communities” where norms are shifting towards more equitable gender relations and helping to foster inclusiveness and agricultural innovation. In those communities, men and women from all economic scales reported significantly higher empowerment and poverty reductions than in the 37 other locations. Greater acceptance of women’s freedom of action, economic activity, and civic and educational participation appears to be a key element.
“In contexts where gender norms are more fluid, new agricultural technologies and practices can become game-changing, increasing economic agency for women and men and rapidly lowering local poverty,” Badstue said.
The contributions and presence of CIMMYT in Afghanistan, which include support for breeding research and training for local scientists, date back several decades. In the last five years, the Agricultural Research Institute of Afghanistan (ARIA) of the country’s Ministry of Agriculture, Irrigation & Livestock (MAIL) has used CIMMYT breeding lines to develop and make available to farmers seed of 15 high-yielding, disease resistant wheat varieties.

High input costs, depleted and degraded natural resources, indiscriminate and imbalanced use of chemical fertilizers and adverse effects from climate change make South Asia – home to about 1.766 billion people (one fourth of the world’s population) – one of the most food insecure regions in the world.
A region-wide shift from conventional agriculture to more sustainable technologies and practices, such as no-till farming or precision land leveling, is critical towards combating these challenges.
Raj Paroda, TAAS chairman, highlighted this need during the dialogue by calling for increased agricultural development assistance from international donors that focuses on mainstreaming sustainable agriculture, a key element in achieving the Sustainable Development Goals (SDGs), a set of 17 global goals spearheaded by the United Nations to end poverty, protect the planet, and ensure prosperity for all.
“The adaptation of conservation agriculture in South Asia, specifically in the Eastern Gangetic Plains, has shown impressive results in terms of saving costs and resources, and boosting income,” said John Dixon, Principal Advisor of ACIAR. “However, the widespread adaptation of conservation agriculture is held back by policy barriers. Institutions and policies have yet to be optimized in a way that facilitates and encourage [its] spread.”
According to Dixon, the regional policy dialogue allowed delegates to share experiences from their own countries and identify which policy changes, institutions and regulations can be adapted in a way that accelerates the widespread adoption of sustainable practices like conservation agriculture.
Paroda closed the dialogue by suggesting that delegates work towards enabling policies to increase funding, coordination and convergence of international private and public funder interest. He suggested the development of an active regional platform that would suggest a roadmap based on the current status, would help share knowledge, initiatives and advocate for policies relating to opportunities for capacity building and regional partnerships. He also identified that the promotion of new innovations through a network of young entrepreneurs and service providers and strong public-private partnerships as key elements to mainstreaming the adoption of sustainable agriculture across the region.
In agrarian countries like Bangladesh, agriculture can serve as a powerful driving force to not only raise family income, but also the nation’s entire economy.
Bangladesh is now threatened by increasing droughts, flooding and extreme weather events due to climate change. In response, rural communities are adapting through innovative, localized solutions that combine sustainable practices and technologies.
Below we detail how these three technologies are transforming farming across Bangladesh.
Axial flow pumps
The axial flow pump is an inexpensive surface water irrigation technology that can reduce costs up to 50 percent at low lifts – areas where the water source is close to the field surface, and therefore is easy to pump up to irrigate fields. Surface water irrigation involves deploying water through low-lift irrigation pumps like the axial flow pump and canal distribution networks managed by water sellers who direct water to farmers’ fields.
For example, 24-year old Mosammat Lima Begum, who lives in a village in Barisal District in Bangladesh, gained access to an axial flow pump and training on its use through CIMMYT’s Cereal Systems Initiative for South Asia (CSISA). After the training, Begum started a business providing irrigation services to her neighbors, boosting her household income by nearly $400 in one year.
Groundwater extraction – a common approach to irrigation in much of South Asia – can result in high energy costs and present health risks due to natural arsenic contamination of groundwater in Bangladesh. Surface water offers a low-energy and low-carbon emissions alternative.

Reapers
Reapers allow farmers to mechanically harvest and plant the next season’s crops, and can save farmers 30 percent their usual harvesting costs. The two-wheeled mechanical reaper is particularly popular in Bangladesh, especially among women since it’s easy to maneuver. It also helps farmers cope with increasing labor scarcity — a trend that has continued to rise as the country develops economically and more people leave rural areas for off-farm employment.
Like the axial flow pump, local service providers with reapers – entrepreneurs who purchase agricultural machinery and rent out their services – are now offering their harvesting services to smallholder farmers at an affordable fee.

Seed fertilizer drills
Seed fertilizer drills till, plant and fertilize crops in lines simultaneously and with greater precision. These drills are frequently used as attachments on two-wheeled tractors.
Around 66 service providers in Barisal, Bangladesh have cultivated more than 640 hectares of land using seed drills for over 1,300 farmers since 2013. These drills cut 30 percent of their fuel costs compared to traditional power tillers, saving them about $58 and 60 hours of labor per hectare. In south-western Bangladesh where USAID’s Feed the Future initiative operates, 818 service providers have cultivated more than 25,500 hectares of land using seed drills for 62,000 small holder farmers till to date.
These drills can also allow farmers to plant using conservation agriculture practices like strip tilling, a system that tills only small strips of land into which seed and fertilizer are placed, which reduces production costs, conserves soil moisture and help boost yields.
Since 2013, CIMMYT has facilitated the sale of over 2,000 agricultural machines to more than 1,800 service providers, reaching 90,000 farmers. Through the CSISA Mechanization and Irrigation project, CIMMYT will continue to transform agriculture in southern Bangladesh by unlocking the potential productivity of the region’s farmers during the dry season through surface water irrigation, efficient agricultural machinery and local service provision.
KATHMANDU, Nepal (CIMMYT) – Members of the Nepal Seed and Fertilizer project (NSAF) met representatives from eleven seed companies at a recent meeting held in Kathmandu, Nepal. Representatives at the meeting discussed progress, challenges, lessons and implementation activities for 2016-17 and developed a work plan for 2107-18.
The discussion added to the Nepal Seed Vision 2013-2025 – a holistic, long-term vision for the country’s seed sector development – which calls for the local development of 40 hybrid vegetable, maize and rice seeds. The plan also encourages the development of products by the private sector and set a target to develop and promote an additional 20 hybrids by the end of 2025.
Nepal’s seed sector is dominated by an informal seed system where farmers produce, retain and exchange their own seeds for subsequent seasons planting. The formal seed system covers about 10 percent of seed transactions, and the country currently imports nearly all its hybrid maize and vegetable seed to meet the increasing demand for high-yielding crop varieties.
The NSAF, led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the United States Agency for International Development, will provide public and private seed companies with parental lines of hybrid maize and other crops that are uniquely adapted to Nepal’s environment. The project also assists local seed companies to have strong R&D as well as facilitates business and market opportunities.
Dyutiman Choudhary, NSAF project coordinator, highlighted the important role of the private sector in developing and disseminating NSAF products and services to farmers and other end users during the meeting. Yagya Prasad Giri , director for crop and horticulture research at the Nepal Agricultural Research Council (NARC), emphasized the importance of collaboration between public and private partners to bridge the demand and supply gap in quality seed production and marketing.
“Enhancing the capacity of local seed institutions is critical in order for the country to achieve its 2025 seed vision,” said Giri while opening the meeting.
Various departments of NARC also discussed progress under NSAF. In addition, CIMMYT and other NSAF representatives travelled to various districts in Nepal to evaluate project activities with various stakeholders.
The Nepal Seed and Fertilizer project (NSAF) is a five year flagship project under the U.S. government’s Feed the Future initiative. NSAF aims to increase agricultural productivity and household income by helping farmers access improved seeds together with best management practices.

With generous funding from the Australian Centre for International Agricultural Research (ACIAR) over the last 15 years, Afghanistan research organizations and the International Maize and Wheat Improvement Center (CIMMYT) have helped supply Afghan farmers with improved varieties and farming practices to boost production of maize and wheat.
“As of 2012, the start of the most recent phase of ACIAR-funded work, Afghanistan partners have developed and released 12 high-yielding and disease resistant bread wheat varieties, as well as 3 varieties of durum wheat, 2 of barley and 3 of maize,” said Rajiv Sharma, a senior wheat scientist at CIMMYT and country liaison officer for CIMMYT in Afghanistan.
Sharma spoke at a workshop, which took place on August 28, with partners from the Agricultural Research Institute of Afghanistan (ARIA) of the country’s Ministry of Agriculture, Irrigation & Livestock (MAIL). The event was organized to review accomplishments and facilitate MAIL’s takeover of all activities, when the project ends in October 2018.
“The pedigrees of all new varieties feature contributions from the breeding research of CIMMYT and the International Winter Wheat Improvement Programme based in Turkey, both responsible for introducing more than 9,000 new wheat and maize lines into the country since 2012,” Sharma added. The International Winter Wheat Improvement Programme (IWWIP) is operated by Turkey, CIMMYT, and ICARDA (the International Center for Agricultural Research in the Dry Areas).
Sharma noted that CIMMYT’s presence in Afghanistan, which includes support for breeding research and training for local scientists, dates back several decades and that the latest achievements with ARIA and other partners and ACIAR support include:
The delineation of wheat agro-climatic zones.
Forecasting climate change impacts on the Afghan wheat crop.
Strategizing to raise wheat production.
Characterization of Afghanistan’s wheat genetic resource collection.
Training abroad for 64 Afghan researchers and in-country for 4,000.
Launching research on wheat hybridization.
In direct partnership with farmers, more than 1,800 farmer field demonstrations, 80 field days, and introduced machinery like seed drills and mobile seed cleaners.
Shared research on and promotion of conservation agriculture, genomic selection, wheat bio-fortification, quality protein maize, climate change, crop insurance and wheat blast resistance and control.
In good years Afghan farmers harvest upwards of 5 million tons of wheat, the country’s number-one food crop, but in some years annual wheat imports exceed 1 million tons to satisfy domestic demand, which exceeds 5.8 million tons.
Multiple partners map avenues to fortify cereal farming
The workshop attracted 45 participants representing ARIA, MAIL, ICARDA, CIMMYT, Michigan State University, ACIAR, the Food and Agriculture Organization of the United Nations (FAO), the Embassy of Australia, and several provincial Directorates of Agriculture, Irrigation & Livestock (DAIL) of Afghanistan.

Among other participants, Mahboobullah Nang, Director of Seed Certification, and Akbar Waziri, Director of the Cereal Department, both from MAIL, offered the Ministry’s support for the continuation of CIMMYT’s longstanding efforts in Afghanistan, particularly in breeding and varietal testing and promotion.
Representing ACIAR, Syed Mousawi commended capacity development activities organized by CIMMYT since the 1970s, which have raised the quality of crop research in Afghanistan and provided a vital link to the global science community over the years.
Participants also recommended extending CIMMYT outreach work, offering training in extension, introducing advanced technologies, and support for and training in varietal maintenance, conservation agriculture, experimental designs, research farm management, data analysis and data management.
With backing from leading international donors and scientists, nine South Asia wheat researchers recently visited the Americas for training on measures to control a deadly and mysterious South American wheat disease that appeared suddenly on their doorstep in 2016.

Known as “wheat blast,” the disease results from a fungus that infects the wheat spikes in the field, turning the grain to inedible chaff. First sighted in Brazil in the mid-1980s, blast has affected up to 3 million hectares in South America and held back the region’s wheat crop expansion for decades.
In 2016, a surprise outbreak in seven districts of Bangladesh blighted wheat harvests on some 15,000 hectares and announced blast’s likely spread throughout South Asia, a region where rice-wheat cropping rotations cover 13 million hectares and nearly a billion inhabitants eat wheat.
“Most commercially grown wheat in South Asia is susceptible to blast,” said Pawan Singh, head of wheat pathology at the International Maize and Wheat Improvement Center (CIMMYT), an organization whose breeding lines are used by public research programs and seed companies in over 100 countries. “The disease poses a grave threat to food and income security in the region and yet is new and unknown to most breeders, pathologists and agronomists there.”
As part of an urgent global response to blast and to acquaint South Asian scientists with techniques to identify and describe the pathogen and help develop resistant varieties, Singh organized a two-week workshop in July. The event drew wheat scientists from Bangladesh, India, Nepal and Mexico, taking them from U.S. greenhouses and labs to fields in Bolivia, where experimental wheat lines are grown under actual blast infections to test for resistance.
The training began at the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) Foreign Disease-Weed Science Research facility at Fort Detrick, Maryland, where participants learned about molecular marker diagnosis of the causal fungus Magnaporthe oryzae pathotype triticum (MoT). Sessions also covered greenhouse screening for blast resistance and blast research conducted at Kansas State University. Inside Level-3 Biosafety Containment greenhouses from which no spore can escape, participants observed specialized plant inoculation and disease evaluation practices.
The group then traveled to Bolivia, where researchers have been fighting wheat blast for decades and had valuable experience to share with the colleagues from South Asia.
“In Bolivia, workshop participants performed hands-on disease evaluation and selection in the field—an experience quite distinct from the precise lab and greenhouse practicums,” said Singh, describing the group’s time at the Cooperativa Agropecuaria Integral Colonias Okinawa (CAICO), Bolivia, experiment station.
Other stops in Bolivia included the stations of the Instituto Nacional de Innovación Agropecuaria y Forestal (INIAF), Asociación de Productores de Oleaginosas y Trigo (ANAPO), Centro de Investigación Agrícola Tropical (CIAT), and a blast-screening nursery in Quirusillas operated by INIAF-CIMMYT.
“Scientists in South Asia have little or no experience with blast disease, which mainly attacks the wheat spike and is completely different from the leaf diseases we normally encounter,” said Prem Lal Kashyap, a scientist at the Indian Institute of Wheat and Barley Research (IIWBR) of the Indian Council of Agricultural Research (ICAR), who took part in the training. “To score a disease like blast in the field, you need to evaluate each spike and check individual spikelets, which is painstaking and labor-intensive, but only thus can you assess the intensity of disease pressure and identify any plants that potentially carry genes for resistance.”
After the U.S.A. and Bolivia, the South Asia scientists took part in a two-week pathology module of an ongoing advanced wheat improvement course at CIMMYT’s headquarters and research stations in Mexico, covering topics such as the epidemiology and characterization of fungal pathogens and screening for resistance to common wheat diseases.

The knowledge gained will allow participants to refine screening methods in South Asia and maintain communication with the blast experts they met in the Americas, according to Carolina St. Pierre who co-ordinates the precision field-based phenotyping platforms of the CGIAR Research Program on Wheat.
“They can now also raise awareness back home concerning the threat of blast and alert farmers, who may then take preventative and remedial actions,” Singh added. “The Bangladesh Ministry of Agriculture has already formed a task force through the Bangladesh Agricultural Research Council (BARC) to help develop and distribute blast resistant cultivars and pursue integrated agronomic control measures.”
The latest course follows on from a hands-on training course in February 2017 at the Wheat Research Center (WRC) of the Bangladesh Agricultural Research Institute (BARI), Dinajpur, in collaboration with CIMMYT, Cornell University, and Kansas State University.
Participants in the July course received training from a truly international array of instructors, including Kerry Pedley and Gary Peterson, of USDA-ARS, and Christian Cruz, of Kansas State University; Felix Marza, of Bolivia’s Instituto Nacional de Innovación Agropecuaria y Forestal (INIAF); Pawan Singh and Carolina St. Pierre, of CIMMYT; Diego Baldelomar, of ANAPO; and Edgar Guzmán, of CIAT-Bolivia.
Funding for the July event came from the Bangladesh Agricultural Research Institute (BARI), the Indian Council of Agricultural Research (ICAR), CIMMYT, the United States Agency for International Development (USAID) and the Bill & Melinda Gates Foundation (through the Cereal Systems Initiative for South Asia), the Australian Centre for International Agricultural Research (ACIAR), and the CGIAR Research Program on Wheat.

EL BATAN, Mexico (CIMMYT) – A new study identifies the key ways to keep up with India’s rising food demand while minimizing greenhouse gas emissions.
Global food production must increase by 70 percent to meet a population of more than 9 billion in 2050. India, with a current population of 1.3 billion and rising, is central to this challenge.
As incomes rise in developing countries, many go through ‘nutrition transition’ away from staple crops towards high greenhouse gas-producing foods like meat and dairy. India, however, has a cultural preference for a lacto-ovo-vegetarian diet — dairy, eggs, and plant-based products — and is likely to differ in this regard from similar developing countries, like China or Brazil.
In India, the majority of greenhouse gas emissions from agriculture are produced from agricultural inputs, farm machinery, soil displacement, residue management and irrigation.
Authors in a recent study from the International Maize and Wheat Improvement Center (CIMMYT) have identified higher emissions from continuously flooded rice, compared to rice which has more frequent periods of water drainage, and a wide range of emissions for other crops due to variation in fertilizer application.
The United Nations Framework Convention on Climate Change has placed emphasis on mitigation of greenhouse gases from agriculture and a number of strategies have been proposed. Measuring emissions from different crops and management systems can help identify the most efficient way to reduce future greenhouse gas emissions while keeping up with food demand.
