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.

NEW DELHI (CIMMYT) – India’s Krishi Unnati Melanational agriculture fair, which was hosted by India’s Department of Agriculture and the Indian Agricultural Research Institute in March, attracted thousands of farmers who attended to learn about the latest agricultural innovations.
The fair was inaugurated by the country’s Prime Minister Shri Narendra Modi, who urged farmers to adopt a “three pillars” support system to insulate themselves from crop losses by farming sustainably. The prime minister recommended growing timber on extra land while adopting animal husbandry and other activities. Modi also presented awards to the best performing states of 2014-2015 and visited exhibitions demonstrating the latest advancements in India’s agriculture sector.

Delegates had the opportunity to visit some 500 stalls set up by public and private sector companies to display new crop varieties, modern technologies and inputs. The Borlaug Institute for South Asia and the International Maize and Wheat Improvement Center displayed joint research activities underway at sites across India.
Farmers and researchers visiting the display learned about farming practices and technology from interpretive staff and through information brochures, which were made available in regional languages.
Climate change is likely to have a huge impact on cereal farmers in India. CIMMYT/Emma Quilligan
EL BATAN, Mexico (CIMMYT) – Developing cereal crops that can withstand the effects of climate change will require global, integrated efforts across crops and disciplines, according to a recent research paper published in the journal “Global Food Security.”
The authors of “An integrated approach to maintaining cereal productivity under climate change” argue that cropping systems could become more resilient in the face of climate change through better coordination. Needs include characterizing target agro-ecosystems, standardization of experimental protocols, comparative biology across cereals (and possibly other crops) and data sharing.
Better integration of research effort across the major cereal crops – including wheat, rice, maize, pearl millet and sorghum – is expected to boost productivity under heat and drought stress, thus helping to increase food security for people in less developed countries, many of which will be severely affected by climate change.
“Most of the big challenges in crop improvement are transnational, therefore a better globally integrated research effort is a triple win scenario,” according to Matthew Reynolds, head of wheat physiology at the International Maize and Wheat Improvement Center (CIMMYT), and lead author of the paper. “It’s more efficient since duplication of effort is reduced, it’s synergistic since we learn simultaneously from multiple crops and environments [or cropping systems], and it’s fasterto achieve impacts because outputs are disseminated more broadly.”
The paper itself is the result of a workshop held in New Delhi in November 2013, which was the first of its kind to bring together researchers from leading universities, CGIAR agricultural research centers, national agricultural research systems and the private sector – working across the five crops – to discuss areas of common interest and potential collaboration.
Wheat, rice, maize, pearl millet, and sorghum make up nearly 45 percent of calories consumed per capita worldwide and about 55 percent in least developed countries, according to the Food and Agricultural Organization of the United Nations. Cereal production is under threat from climate change, which subjects crops to heat and drought stress. Diminishing water supplies, increasing populations, urbanization, shifting diets and increasing demand for fodder and fuel is also putting pressure on cereal production. Taking all these factors into account, researchers project that yield growth rates of 1.2 percent to – 1.7 percent will be required to meet global demand and reduce malnutrition.
The authors of the paper, including representatives from the U.S. Agency for International Development and the Bill & Melinda Gates Foundation, identified priority traits for heat and drought tolerance across the cereal crops, and also called for more effective collaborations so that these traits can be modelled, tested at common phenotyping platforms and the resulting data shared with other researchers worldwide as global public goods.
“This paper has provided a baseline about what needs to be done,” said O.P. Yadav, director of the Central Arid Zone Research Institute at the Indian Council of Agricultural Research. “It has also shown what is achievable, once various institutes decide to work together with a common goal and become collaborative stakeholders in increasing the resilience of diverse cropping systems.”

ISLAMABAD (CIMMYT) — Development and agricultural professionals attending a planning meeting in Islamabad in March discussed the importance of follow-up surveys for project evaluation and intervention impact, particularly in relation to the Agricultural Innovation Program for Pakistan (AIP).
“This is the right time to assess AIP’s performance, and we need to focus on the demands of the farmers, their challenges and work out a way forward for them to improve their agricultural productivity,” said Imtiaz Muhammad, CIMMYT country representative in Pakistan.
Nazim Ali, AIP activity manager, explained the importance of follow-up surveys and their significance in project evaluation and impact assessment. AIP primary partners shared lessons learned from baseline surveys and presented a work plan for follow-up surveys.
Akhter Ali, CIMMYT agricultural economist, spoke about the methodology used in follow-up surveys, sampling techniques, geographic spread and data analysis techniques.
Participants reached consensus on the following points:
Follow-up survey questionnaires must be aligned with indicators, which AIP is currently reporting to USAID
Follow-up survey questionnaires will be refined internally
Women enumerators should collect sex-disaggregated data sets
For all AIP interventions, samples need to be representative
Agreed time frame for completion of the follow up surveys is tentatively December
For all interventions, AIP partners agreed on documentation of impact through follow up surveys.
These joint efforts will enable smallholder farmers to improve agricultural productivity and livelihoods across different agro-ecological regions of Pakistan.

DHAKA, Bangladesh (CIMMYT) — On a recent visit to Bangladesh, Martin Kropff , director general of the International Maize and Wheat Improvement Center (CIMMYT) held discussions with partners and government officials on combating wheat blast disease and other aspects of maintaining food security in the country.
Meetings were held with Bangladesh’s agriculture minister and member of Parliament Begum Matia Chowdhury and Secretary of Agriculture Mohammad Moinuddin Abdullah, where CIMMYT’s activities in Bangladesh were also discussed. Wheat blast is one of the most feared and intractable wheat diseases.
A new, severe outbreak of the disease in Bangladesh validated the prediction of the spread of the disease beyond its origins in Latin America to Africa and South Asia. The spread of wheat blast could be devastating to South Asia, which is home to 300 million undernourished people and whose inhabitants consume over 100 million tons of wheat each year.

During a two day field visit, Kropff saw the impacts of wheat blast in the Bangladesh Agricultural Research Institute’s (BARI) research station in Jessore and farmers’ fields. He also spent the visit meeting Bangladeshi farmers, observing mechanization scaling efforts and visiting a range of CIMMYT varietal and agronomic research trials and demonstrations funded by the U.S. Agency for International Development and the Australian Centre for International Agricultural Research in Jessore and Dinajpur districts. In addition he held discussions with scientists from BARI and visited the organization’s headquarters in Gazipur and

One of the side-effects of the Green Revolution, which began in the 1960s and led to large increases in crop production, has been a change in the cropping patterns in many parts of India.
Farmers have shifted to crops with higher yields. In the Indo-Gangetic plains, for example, rice and wheat have replaced many other crops. This has reduced crop diversity, affected dietary patterns, and led to malnutrition due to a poor supply of proteins, vitamins, iron and zinc.
Wheat is the staple diet in Uttar Pradesh and Bihar. Farmers in those states typically have very small landholdings and consume about 70 per cent of the food they produce. One essential mineral missing from their diet is zinc. A zinc deficiency leads to malfunctioning of several proteins and enzymes, and manifests itself in a variety of diseases, including diarrhea, skin and respiratory disorders.
One way of making up for this kind of deficiency is to provide fortification by adding missing nutrients to food, but this is complex for several reasons, including price increases, the problem of quality control, and the possibility of adulteration.
We tested the genetic bio-fortification technology for enhancing the zinc content in wheat crops under the HarvestPlus project of CIMMYT and the International Center for Tropical Agriculture, funded by the Bill & Melinda Gates Foundation. Bio-fortification is a seed-driven technology that enables crops to extract a higher amount of zinc from the soil and store it in the edible parts.
Through cross-breeding, we produced several thousand wheat genotypes and screened them for high zinc content and high yield. In India, a new variety would be unacceptable if it does not deliver a higher yield than the varieties already under cultivation. We isolated several of these cross-bred varieties that had both high zinc and high yield, and put them through field trials. The existing varieties of wheat crop had 29 parts per million (ppm) of zinc and the varieties we selected had 40 to 45 ppm of zinc.
These field trials were conducted at 70 different locations. Two specific varieties of wheat were then distributed to about 5,000 farmers for cultivation.
The next stage is national trials, which will be conducted by the Indian Council of Agricultural Research (ICAR). The first thing that ICAR does is to put the recommended varieties to disease trial. The ICAR tests take about three years. One of the varieties, BHU-35, has recently cleared the disease-testing stage and is ready to be released in Uttar Pradesh for cultivation, after a few more regulatory clearances.
Seven other varieties are currently undergoing disease testing, and in the next few years, many other zinc-rich wheat crops will be ready for cultivation.

Research shows conservation agriculture increases the income of farmers, moderates canopy temperatures, improves irrigation productivity and reduces greenhouse gas emissions in cereal systems in the Indo-Gangetic plains.
In an August 2015 article in the Journal of Integrative Agriculture, researchers report that a comprehensive literature review and evidence collected from on-farm trials showed that conservation agriculture – defined as minimal soil disturbance and permanent soil cover combined with appropriate rotations – improved farmers’ income, helped crops sustain or adapt to heat and water stresses, and reduced agriculture’s contribution to greenhouse gas emissions in cereal systems in South Asia.

Farmers reap economic benefits
Conservation agriculture recommends minimal soil disturbance, most commonly tillage. Farmers who practiced zero tillage saved 23 percent in production costs by avoiding preparatory tillage and reducing the number of times fields were irrigated, while reaping the same or slightly higher yields.
Minimizing heat stress
High temperatures during the maturity stage cause wheat to decrease grain size, lowering overall yields, a phenomenon known as “terminal heat effect.” Farmers who practice conservation agriculture avoid this heat stress because residues left on the surface of the field conserve soil moisture, enhancing transpiration and creating a cooling effect – thus avoiding reduced yields caused by terminal heat effect.
Efficient use of water resources
Researchers found multiple examples that the zero tillage component of conservation agriculture led to significant water savings in both rice and wheat systems. Water savings accrued across systems. In rice-wheat systems, retention of wheat residues reduces water use in rice, and retention of rice residues causes reduced water use in wheat. Non-requirement of preparatory tillage advances the planting times thereby increasing rainwater-use efficiency and utilizing residual moisture from the previous crop.
Decrease in greenhouse gas emissions
Minimizing soil disturbance allows for soil carbon to accumulate, causing a net soil carbon gain. Although scientists are still debating the extent of soil carbon sequestered through conservation agriculture, indirect emissions reductions are numerous: less power and fuel consumption due to decreased tillage in conservation agriculture, decreased labor from machines and humans, and slower depreciation of equipment.
Business-as-usual production practices such as conventional tillage and farmers’ nutrient and irrigation management systems are greenhouse gas-intensive, while zero tillage reduces energy consumption in land preparation and crop establishment and efficient use of water resources reduces energy needs from pumping. Leaving residues in the field increases soil health and fertility, thereby reducing the need for chemical fertilizers.
Researchers found that, on average, farmers could save 36 liters of diesel per hectare, equivalent to a reduction in 93 kg CO2 emission per hectare per year by practicing zero tillage for land preparation and crop establishment in the rice-wheat system typical on the Indo-Gangetic Plain. Given that 13.5 million hectares are under rice-wheat system cultivation in the region, this represents a reduction of 12.6 megatons of CO2 equivalent.
New technologies increase uptake of conservation agriculture
Despite excellent productivity, economic gains and environmental benefits, adoption of conservation agriculture in South Asia is still relatively slow, most likely due to various technological and socio-economic factors. It takes years and ample evidence for farmers to change the entrenched habit of tillage with planting. And it is a process.
For example, some farmers have adopted zero-tillage in wheat production, primarily to facilitate early planting, lower production costs and increase yields (and therefore profitabilitiy). However, these same farmers still prefer to practice tillage and puddling (wet-tillage) in their rice crops for weed control and reduction in percolation loss of water/nutrient. Also, farmers tend to burn crop residues to facilitate planting with the zero-tillage drill. To realize the full potential of conservation agriculture, all crops in rotation have to be brought under zero tillage, and crop residues will have to be used as soil surface mulch.
Due to the recent development of the “Turbo Happy Seeder,” which can drill seed and fertilizer directly through loose and anchored crop residues, farmers are gradually moving towards zero tillage across the agriculture system.
Farmers who practice conservation agriculture also must adjust their nutrient management systems in order to maximize crop productivity decrease costs. Conventional fertilizer recommendations have been calibrated based on tillage-based systems are thus not necessarily appropriate for conservation agriculture systems, including nutrient stewardship (applying the right source of fertilizer at the right time in right place using right method).
Crop residue management is essential for continuous coil cover, an important component of conservation agriculture, but farmers are faced with competing uses of crop residue as livestock feed, fuel, mulch and compost. Local adaptive research is needed to address strategic residue and nutrient management, weed control and scale-appropriate machinery development.
Such a paradigm shift in crop management requires a mindset transition among farmers and other value chain actors, including researchers, extension agents, market players and other institutions. Though it is recognized that transition takes time, recent progress and development in weed control and nutrient management systems signal that practice of conservation agriculture is growing across the region, including among different socio-economic groups and farm typologies.

United States Agency for International Development (USAID) Mission Director John Groarke presented new varieties of maize seed to Pakistani research organizations and private-sector seed companies on 17 February at the National Agricultural Research Center in Islamabad, according to a U.S. embassy press release.
These varieties were developed by the Agricultural Innovation Program (AIP), a joint effort led by CIMMYT and supported by USAID, to jump-start the production of quality hybrid maize seed in Pakistan. The varieties distributed are resistant to drought and heat, have enhanced nutritional quality and increased tolerance to insect attacks and low soil nitrogen.
AIP for Pakistan is working to sustainably increase agricultural productivity and incomes in the agricultural sector through the promotion and dissemination of modern technologies/practices in the livestock, horticulture (fruits and vegetables) and cereals (wheat, maize and rice) sector. The $30 million initiative also collaborates with the International Livestock Research Institute (ILRI), the World Vegetable Center (AVRDC), the International Rice Research Institute (IRRI), the University of California – Davis and the Pakistan Agricultural Research Council (PARC).

NEW DELHI — The International Maize and Wheat Improvement Center (CIMMYT) Director General Martin Kropff presented the organization’s draft strategy with its unifying vision of ‘One CIMMYT’ at the staff session in the Delhi office during his India visit from 24 February to 3 March. Kropff highlighted that CIMMYT’s excellent scientific work, global presence, partnerships and people are its strengths. However, the organization needs to focus on engaging with new donors and increasing organizational effectiveness in the future.
In the meeting, Kropff shared reflections on his eight months at CIMMYT, emphasizing that improving integration among different projects, teams and geographies through shared values and teamwork will help to achieve a common mission: “Maize & Wheat Science for Improved livelihoods.”

Staff discussed different elements of the strategy in smaller group breakout sessions and suggested various steps to raise scientific excellence, increase capacity building and to achieve the One CIMMYT objective across all regions. The groups agreed that the “will play a key role in bringing innovative ideas and developing the next generation of well-trained scientists.
During his first visit to the state of Bihar, Kropff visited BISA research farm at Pusa, where he was accompanied by Hari S. Gupta, Director General of BISA, senior officials from Rajendra Agriculture University and CIMMYT scientists. Raj Kumar Jat, BISA cropping systems agronomist, explained the positive impacts of long-term conservation agriculture research on productivity, profitability and soil health at the farm. Kropff saw demonstrations of small farm mechanization, climate-smart practices and the latest research tools and techniques for breeding crop varieties.
The team visited the research platform of the Cereal Systems Initiative for South Asia (CSISA) project in Patna. R.K. Malik, CIMMYT cropping systems agronomist, highlighted that research results have shown that using shorter hybrid rice varieties can help facilitate an early rice harvest and advance wheat sowing. This will help combat the adverse effects of climate change such as rising heat during the wheat ripening phase and will increase wheat productivity in Bihar. Kropff also interacted with women farmers and service providers to understand their business development services around service provision model.
Kropff and the CIMMYT-BISA team then met with Nitish Kumar, Bihar Chief Minister to discuss how CIMMYT and BISA’s work on new technologies could be helpful to double the productivity in the state with less cost and less water while improving the soil quality. The meeting was also attended by the senior officials of the state government and the Agricultural Production Commissioner of Bihar.

FOR IMMEDIATE RELEASE
Findings can help to boost wheat’s climate resilience worldwide
For the first time ever, a research team from China, India, Mexico, Uruguay, and the USA has genetically characterized a collection of 8,400 centuries-old Mexican wheat landraces adapted to varied and sometimes extreme conditions, offering a treasure trove of potential genes to combat wheat’s climate-vulnerability.
Published today in Nature Scientific Reports and led by scientists from the Mexico-based International Maize and Wheat Improvement Center (CIMMYT), the study details critical genetic information about Mexican landraces for use in breeding to boost global wheat productivity.
This is essential, given the well-documented climate effects that imperil key wheat-growing areas, according to Sukhwinder Singh, CIMMYT wheat scientist and co-author of the report.
“The landraces, known as Creole wheats, were brought to Mexico as early as the 16th Century,” said Singh, who also credited the study to MasAgro, a long-term rural development project between Mexico and CIMMYT. “Wheat is not native to Mexico, but this gave the Creoles time to toughen in zones where late-season temperatures can hit highs of 40 degrees Centigrade (104 degrees Fahrenheit).”
Heat can wreak havoc with wheat’s ability to produce plump, well-filled grains. Research has shown that wheat yields plummet 6 percent for each 1-degree-Centigrade rise in temperature, and that warming is already holding back yield gains in wheat-growing mega-regions such as South Asia, home to more than 300 million undernourished people and whose inhabitants consume over 100 million tons of wheat each year.
“Typically, massive seed collections constitute ‘black boxes’ that scientists have long believed to harbor useful diversity but whose treasures have remained frustratingly inaccessible,” Singh explained. “New technology is helping to change that. As part of MasAgro’s ‘Seeds of Discovery Component,’ the team used the latest genotyping-by-sequencing technology and created unique sets of the landrace collections that together capture nearly 90 percent of the rare gene variants, known as ‘alleles.’ ”
According to Kevin Pixley, director of CIMMYT’s genetic resources program and an expert crop breeder, wheat scientists will be able to home in on groups of landraces from regions with conditions similar to those they presently target or will target in coming decades. “The next step is for breeders to identify seed samples and genes for their programs; say, alleles common to a set of landraces from a heat-stressed area, providing a valuable starting point to exploit this newly-revealed diversity.”
A pillar for global food security, wheat provides 20 percent of protein and calories consumed worldwide and up to 50% in developing countries. A 2015 World Bank report showed that, without action, climate change would likely spark higher agricultural prices and threaten food security in the world’s poorer regions.

About CIMMYT
The International Maize and Wheat Improvement Center (CIMMYT), is the global leader in research for development in wheat and maize and wheat- and maize-based farming systems. From its headquarters in Mexico and 14 global offices, CIMMYT works throughout the developing world with hundreds of partners to sustainably increase the productivity of maize and wheat systems, thus contributing to better food security and livelihoods. CIMMYT is a member of the 15-member CGIAR Consortium and leads the CGIAR Research Programs on Wheat and Maize. CIMMYT receives support from national governments, foundations, development banks and other public and private agencies.
This story is one in a series of features written during CIMMYT’s 50th anniversary year to highlight significant advancements in maize and wheat research between 1966 and 2016.
EL BATAN, Mexico (CIMMYT) – The International Maize and Wheat Improvement Center (CIMMYT) stepped onto the global stage during the “Swinging Sixties.” The decade was defined by social upheaval dominated by left-right political tensions provoked in large measure by Cold War rivalries between the United States and the former Soviet Union.
It was 1966 when Mexico’s Office of Special Studies, formed in the 1940s as an agency of the country’s Ministry of Agriculture and Livestock in partnership with the Rockefeller Foundation to improve bean, maize, potatoes and wheat crops, became CIMMYT.
That same year, civil war exploded in Chad, China’s cultural revolution began, Indira Gandhi became India’s first woman prime minister and musician John Lennon met his future wife Yoko Ono. In the United States, the feminist National Organization for Women (NOW) was formed. Throughout the decade, as the Vietnam War rumbled and more than 30 countries declared independence in Africa, women in many developing countries struggled to gain basic human rights, including the chance to vote.
In wealthy western nations, the “Women’s Liberation Movement,” ultimately known as second-wave feminism, emerged, supplanting women’s suffrage movements and deepening debates over women’s rights.
At CIMMYT, efforts to meet agricultural needs of women farmers and those in charge of nutritional wellbeing within the household to bolster global food security took shape.
Women make up 43 percent of the agricultural labor force in developing countries, according to the U.N. Food and Agriculture Organization (FAO). However, rural women suffer systematic discrimination with regard to their ability to access resources for agricultural production and socio-economic development.
Now referred to as “gender issues” and “gender relations,” debates over how to address inequity on farms and in the workplace are ongoing at CIMMYT. Rather than focusing specifically on women’s rights, gender studies focus on how notions of women or men are determined through characteristics societies attribute to each sex. Gender relations consider how a given society defines rights, responsibilities, identities and relationships between men and women.
As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to one-quarter of the world’s daily energy intake, and contributing 27 percent of the total calories in the diets of people living in developing countries, according to FAO.
Globally, if women had the same access to agricultural production resources as men, they could increase crop yields by up to 30 percent, which would raise total agricultural output in developing countries by as much as 4 percent, reducing the number of hungry people by up to 150 million or 17 percent, FAO statistics show.
SCIENTIFIC CONTRIBUTIONS
From the outset, women scientists played a key role as maize and wheat researchers at CIMMYT.
Evangelina Villegas, who in 2000 became the first woman to win the World Food Prize, joined CIMMYT in 1967. She shared the prestigious award with CIMMYT colleague Surinder Vasal for efforts and achievements in breeding and advancing quality protein maize to improve productivity and nutrition in malnourished and impoverished areas worldwide.
Maize scientist Marianne Bänziger joined CIMMYT in 1992. When she was transferred to Zimbabwe in 1996 to lead the Southern African Drought and Low Soil Fertility Project (SADLF), she became the first woman scientist at CIMMYT posted to a regional office.
“In the good old days, women scientists were considered an oddity – women were considered something special, even though a scientist like Eva Villegas was very well integrated into CIMMYT,” said Bänziger, who now serves as CIMMYT’s deputy director general.
Bänziger’s work was centered on eastern and southern Africa, where the livelihoods of about 25 million people depend directly on agriculture and maize is the staple crop of choice. Drought and poor soil quality often erode food security and increase socio-economic pressures in the region.
Bänziger became known as “Mama Mahindi,” Swahili for “Mother Maize,” for her work developing stress-tolerant maize and for fostering the widespread access of seed producers and farmers to improved drought-tolerant maize now grown by at least 2 million households.
Denise Costich manages the world’s biggest maize gene bank at CIMMYT headquarters near Mexico City. She joined CIMMYT to work closely with farmers. She now holds farmer field days to help improve seed distribution. Her aims include understanding how best to move genetic resources from gene bank to field through breeding, so they become products that help improve food security.
“I was always encouraged to go as far as I could,” Costich said. “The way I prove that women can be scientists is by being a scientist. Let me get out there and do what I can do and not spend a lot of time talking about it.”
Wheat physiologist Gemma Molero spent two years inventing a hand-held tool for measuring spike photosynthesis, an important part of the strategy for developing a high-yielding plant ideotype. Now, Bayer Crop Science is interested in joining a collaborative project with CIMMYT, which will focus around use of the new technology.
Wheat scientist Carolina Saint Pierre has made important contributions towards obtaining the first permits for growing genetically modified wheat in open field trials in Mexico. The trials have allowed the identification of best-performing genetically modified wheat under water stress and helped understand the genetic control of physiological mechanisms related to drought.
WORKPLACE EQUITY
Despite a daycare at headquarters and other efforts to encourage gender equity, women scientists at CIMMYT continue to face different burdens than men in maintaining a work-life balance.
“Whether you are a western woman in a white-collar job worrying about a daycare or a woman farmer in a developing country worrying about her aging parents, women have a different level of responsibility,” said Jenny Nelson, manager of the Global Wheat Program.
A lot of women drop out of agricultural science after earning their doctoral degrees once they have a family, said Costich, acknowledging a challenge many women working in agricultural science face related to long hours and travel requirements.
“As a young woman I have to work very hard – I have to work even harder than men in the field to demonstrate my abilities and gain respect,” Molero said.
Overall, economists concur that gender inequity and social disparities have a negative impact on economic growth, development, food security and nutrition.
Through various projects, CIMMYT aims to address the challenges of gender equity to improve development potential. For example, CIMMYT researchers are among the leaders of a global push to encode gender into agricultural research in tandem with other international research partnerships.
In more than 125 agricultural communities in 26 countries, a field study of gender norms and agricultural innovation, known as “Gennovate,” is underway. The aim is to help spur a transformation in the way gender is included in agricultural research for development. Gennovate focuses on understanding how gender norms influence the ability of people to access, try out, adopt or adapt new agricultural technology.

EL BATAN, Mexico (CIMMYT) – With Syria torn apart by civil war, a team of scientists in Mexico and Morocco are rushing to save a vital sample of wheat’s ancient and massive genetic diversity, sealed in seed collections of an international research center formerly based in Aleppo but forced to leave during 2012-13.
The researchers are restoring and genetically characterizing more than 30,000 unique seed collections of wheat from the Syrian genebank of the International Center for Agricultural Research in the Dry Areas (ICARDA), which has relocated its headquarters to Beirut, Lebanon, and backed up its 150,000 collections of barley, fava bean, lentil and wheat seed with partners and in the Global Seed Vault at Svalbard, Norway.
In March 2015, scientists at ICARDA were awarded The Gregor Mendel Foundation Innovation Prize for their courage in securing and preserving their seed collections at Svalbard, by continuing work and keeping the genebank operational in Syria even amidst war.
“With war raging in Syria, this project is incredibly important,” said Carolina Sansaloni, genotyping and DNA sequencing specialist at the Mexico-based International Maize and Wheat Improvement Center (CIMMYT), which is leading work to analyze the samples and locate genes for breeding high-yield, climate resilient wheats. “It would be amazing if we could be just a small part of reintroducing varieties that have been lost in war-torn regions.”
Treasure from wheat’s cradle to feed the future
Much of wheat seed comes from the Fertile Crescent, a region whose early nations developed and depended on wheat as the vital grain of their civilizations. The collections could hold the key for future breeding to feed an expanding world population, according to Sansaloni.
“An ancient variety bred out over time could contain a gene for resistance to a deadly wheat disease or for tolerance to climate change effects like heat and drought, which are expected to become more severe in developing countries where smallholder farmers and their families depend on wheat,” she explained.
Cross-region partners, global benefits
Sansaloni’s team has been sequencing DNA from as many as 2,000 seed samples a week, as well as deriving molecular markers for breeder- and farmer-valued traits, such as disease resistance, drought or heat tolerance and qualities that contribute to higher yields and grain quality.
They are using a high-end DNA sequencing system located at the Genetic Analysis Service for Agriculture (SAGA), a partnership between CIMMYT and Mexico’s Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), and with the support of a private company from Australia, Diversity Arrays Technology.
The sequencer at SAGA can read 1600 samples of seed at once and develops more data than ever before. The HiSeq 2500 boils down data and shows the information at a “sequence level”, for example, height variations among wheat varieties.
Worldwide, there are few other machines that produce this kind of data and most are owned by private companies, explained Sansaloni. This was the first non-Latin American based project used by the HiSeq 2500.
“The success of this project shows what a fantastic opportunity for international collaboration we now have,” Sansaloni said. “I can’t even put a value on the importance of the data we have collected from this project. It’s priceless.”
After data has been collected, seed samples will be “regenerated” by ICARDA and CIMMYT. That is, the process of restoring old seed samples with healthy new seeds.
ICARDA and CIMMYT will share seed and data from the project and make these results available worldwide.
“With these new seeds, we hope to reconstruct ICARDA’s active and base collection of seeds over the next five years in new genebank facilities in Lebanon and Morocco,” said Fawzy Nawar, senior genebank documentation specialist, ICARDA.
Funded through the CGIAR Research Program on Wheat, the effort benefits both of the international centers, as well as wheat breeding programs worldwide, said Tom Payne, head of CIMMYT’s Wheat Germplasm Bank. “ICARDA is in a difficult situation, with a lack of easy access to their seeds and no facilities to perform genotyping,” he explained. “This was the perfect opportunity to collaborate.”
M.L. Jat shows resilient cropping system options for eastern Indo-Gangetic plains at BISA farm
CIMMYT Senior Scientist M.L. Jat has received India’s National Academy of Agricultural Sciences (NAAS) fellowship in Natural Resource Management for his “outstanding contributions in developing and scaling” conservation agriculture-based management technologies for predominant cereal-based cropping systems in South Asia.
Research such as M.L.’s is more important every day, as we learn to do more with less on a planet with finite resources and changing climate. Sustainable innovation, including climate-smart agriculture, is a major theme at the ongoing COP21 climate talks where global leaders are gathered to decide the future of our planet. M.L. tells us below how CA can play a part in climate change mitigation and adaptation, and the future of CA in South Asia.
What are the major threats global climate change poses to South Asian agriculture?
South Asia is one of the most vulnerable regions in the world to climate change. With a growing population of 1.6 billion people, the region hosts 40% of the world’s poor and malnourished on just 2.4% of the world’s land. Agriculture makes up over half of the region’s livelihoods, so warmer winters and extreme, erratic weather events such as droughts and floods have an even greater impact. Higher global temperatures will continue to add extreme pressure to finite land and other natural resources, threatening food security and livelihoods of smallholder farmers and the urban poor.
How does CA mitigate and help farmers adapt to climate change?
In South Asia, climate change is likely to reduce agricultural production 10‐50% by 2050 and beyond, so adaptation measures are needed now. Climate change has complex and local impacts, requiring scalable solutions to likewise be locally-adapted.
Climate-smart agriculture (CSA) practices such as CA not only minimize production costs and inputs, but also help farmers adapt to extreme weather events, reduce temporal variability in productivity, and mitigate greenhouse gas emissions, according to numerous data on CA management practices throughout the region.
What future developments are needed to help South Asian farmers adapt to climate change?
Targeting and access to CA sustainable intensification technologies, knowledge, and training – such as precision water and nutrient management or mechanized CA solutions specific to a farmer’s unique landscape – will be critical to cope with emerging risks of climate variability. Participatory and community-based approaches will be critical for scaled impact as well. For example, the climate smart village concept allows rural youth and women to be empowered not only by becoming CA practitioners but also by serving as knowledge providers to the local community, making them important actors in generating employment and scaling CA and other climate-smart practices.
Where do you see your research heading in the next 10-15 years?
Now that there are clear benefits of CA and CSA across a diversity of farms at a regional level, as well as increased awareness by stakeholders of potential challenges of resource degradation and food security in the face of climate change, scaling up CA and CSA interventions will be a priority. For example, the Government of Haryana in India has already initiated a program to introduce CSA in 500 climate smart villages. Thanks to this initiative, CA and CSA will benefit 10 million farms across the region in the next 10-15 years.
Climate-Smart Villages
Climate-Smart Villages are a community-based approach to adaptation and mitigation of climate change for villages in high-risk areas, which will likely suffer most from a changing climate. The project began in 2011 with 15 climate-smart villages in West Africa, East Africa and South Asia, and is expanding to Latin America and Southeast Asia. CIMMYT is leading the CCAFS-CSV project in South Asia.
“CIMMYT is famous for helping farmers all over the world, but what fewer people know is that they also help Mexican researchers and students who will become the next generation of researchers through the courses and workshops they offer,” said Alejandro Ledesma, maize researcher at Mexico’s National Forestry, Agricultural and Livestock Research Institute (INIFAP).

The Seeds of Discovery (SeeD) project seeks to empower the next generation of Mexican scientists to use maize and wheat biodiversity to effectively meet the needs of Mexican agriculture in the future. By providing professional agricultural research and development opportunities for current and future maize and wheat scientists, SeeD works to ensure that the materials they develop will reach those who need it most. For this reason, SeeD is developing a platform of publicly available data and software tools that enable the efficient use of maize and wheat genetic resources. These genetic resources, or biodiversity, include more than 28,000 maize and 140,000 wheat samples, known as accessions, that are conserved in CIMMYT’s seed bank and available to researchers worldwide.
Genetic resources are the raw materials or building blocks used to develop new maize and wheat varieties needed to meet the demands of a growing population in a changing climate. Many of these maize and wheat accessions contain positive traits such as drought tolerance or disease resistance, which if bred into new varieties have the potential to improve food security and livelihoods in countries such as Mexico in the global south.
However, the specific potential impact of SeeD on Mexican agriculture and society will only be realized if breeders and scientists effectively use the products resulting from the project. By inviting researchers, professors and students to participate in workshops, training courses and diverse research projects, a growing cadre of scientists is learning how to use the databases and software tools developed by SeeD and validating their utility.

“Sharing the knowledge generated by SeeD and making it available to the scientific community will help accelerate the development of new varieties that will benefit long-term food security in Mexico and the world,” said Cynthia Ortiz, a graduate student in biotechnology at the Center for Research and Advanced Studies of the National Polytechnic Institute (CINVESTAV) in Mexico City.
Ortiz is conducting research for her Master of Science thesis mentored by SeeD scientist Sukhwinder Singh, who is helping her map the quantitative trait loci (QTL) for phenological and grain yield-related traits in wheat varieties created by crossing synthetic wheat varieties with elite lines. She has participated in two SeeD workshops focusing on wheat phenotyping for heat, drought and yield as well as on the use of the maize and wheat molecular atlas, where she learned to use SeeD software such as Flapjack and CurlyWhirly to visualize the results of genetic diversity analyses.
“The materials SeeD has developed have opened the door for identifying genetic resources with positive traits such as heat and drought tolerance, or resistance to pests and diseases that affect crops all over the world,” Ortiz said. “And the best part is that at the same time, they have sought to protect the genetic diversity of these crops, using the native biodiversity we have in Mexico and the world to confront the challenge of ensuring food security.”
David Gonzalez, a recent graduate of the Chapingo Autonomous University in Texcoco, a city about 30 km (20 miles) from Mexico City, agrees. He worked with SeeD scientists Sarah Hearne and Terence Molnar on his Master of Science thesis, identifying genetic resources with resistance to the maize leaf disease “tar spot complex” (TSC) by using genome-wide association study (GWAS) and genomic selection.

“The software and databases SeeD develops for analyzing genotypic and phenotypic data are novel tools that can be used for research as well as academic purposes,” Gonzalez said. “They are a valuable resource that can be utilized by academic institutions to train students in genetic analysis.”
Gonzalez attended the CIMMYT training course “Technologies for Tropical Maize Improvement,” where he learned about new tools for field trial design, data analysis, doubled haploid technology, molecular markers, GWAS and genomic selection.
“This training, as well as the valuable help and support from CIMMYT scientists, really helped me develop myself professionally,” he said. “It was exciting to work with such an ambitious project, doing things that have never been done before to discover and utilize maize and wheat genetic diversity for the benefit of farmers. I look forward to using what I’ve learned in my future career to develop varieties that meet the needs of farmers in Latin America.”
SeeD is a joint initiative of CIMMYT and the Mexican Ministry of Agriculture (SAGARPA) through the MasAgro project. SeeD receives additional funding from the CGIAR Research Programs on Maize (MAIZE CRP) and Wheat (WHEAT CRP), and from the UK’s Biotechnology and Biological Sciences Research Council (BBSRC).

The recent 7.6 magnitude earthquake that struck Nepal on 25 April, followed by a 7.3 magnitude aftershock on 12 May and several hundred additional aftershocks, has had huge negative impacts on the country’s agriculture and food security. Around two-thirds of Nepal’s population rely on agriculture for their livelihoods, and agriculture contributes 33% of Nepal’s GDP. It is estimated that about 8 million people have been affected by the earthquakes, with smallholders in hilly regions being the hardest hit.
The earthquakes damaged or destroyed agricultural assets, undermining the longer-term food production capacity of farm families and disrupting critical input supply, trade, and processing networks. Farmers lost grain and seed stocks, livestock, agricultural tools and other inputs, and are facing significant labor shortages. Widespread damage to seed and grain storage facilities has affected smallholder farmers’ ability to secure their harvested crops during the rainy season.
In response to the devastation, USAID-Nepal has provided US$1 million to the CIMMYT-led Cereal Systems Initiative for South Asia in Nepal (CSISA-NP) for earthquake relief and recovery. The Earthquake Recovery Support Program will be implemented for a period of 13 months in close coordination with the Ministry of Agricultural Development (MoAD), Department of Agriculture, Department of Livestock Services, Nepal Agricultural Research Council, and District Disaster Relief Committee. The districts that will receive support include Dolkha, Kavre, Khotang, Makwanpur, Nuwakot, Ramechap, Sindhupalchowk, and Solukhumbu, which suffered particularly high levels of damage.
According to Andrew McDonald, CIMMYT Principal Scientist and CSISA Project Leader, “Even if seed is available, farmers’ ability to plant and harvest crops has been severely diminished due to the loss of draft animals and the exacerbation of labor shortages.” To aid them, the earthquake recovery program will provide more than 33,000 farming households with 50,000 grain storage bags, 30 cocoons for community grain storage, 400 mini-tillers and other modern agriculture power tools (e.g., seeders, reapers, and maize shellers), 800 sets of small agricultural hand tools, and 20,000 posters on better-bet agronomic practices for rice and maize.
“First we will focus on getting horse-powered mini-tillers into affected communities, and subsequently broadening the utility of these machines to power a host of essential agricultural activities including seeding, reaping, threshing, and shelling, as well as driving small pumps for irrigation,” said Scott Justice, Agricultural Mechanization Specialist, CSISA-NP.

At the program’s inception workshop on 28 August, Beth Dunford, USAID-Nepal Mission Director, remarked that USAID-Nepal has arranged for a special fund to help earthquake-affected people. Beyond the devastation of houses and public infrastructure such as roads, the earthquake has seriously disrupted agriculture and the rural economy in the impacted districts. Re-establishing vital agricultural markets and services is key to how quickly these communities will recover from the earthquake, underlined Dunford.
To coordinate and monitor program activities effectively, management committees at the central, district, and local levels have been formed with the purpose of identifying the earthquake-affected areas within a district and ensuring efficient and transparent distribution of aid items.
MoAD Joint Secretary Rajendra Adhikari highlighted that the Ministry feels a real sense of ownership over this program and is committed to implementing program activities through its network. The farm machinery support program will be a perfect platform for MoAD to expand its farm mechanization program into other areas of the country. The Earthquake Recovery Support Program also aligns with the Nepalese Government’s agricultural development strategies, which focus on community-wide inclusive development.
