Farmers, environment, and carbon markets to profit from more precise fertilizer management, study shows

EL BATÁN, MEXICO – 24 APRIL 2018–Farmers of irrigated wheat can increase profits and radically reduce greenhouse gas emissions by applying fertilizer in more precise dosages, according to a new study.

Published today in the journal Agriculture, Ecosystems and Environment, the study shows that farmers in the Yaqui Valley, a major breadbasket region in northwestern Mexico that covers over 1.5 times the area of the Mexico City, are applying significantly more nitrogen fertilizer than they need to maximize wheat yields.

Lower application of nitrogen fertilizer would cut the region’s yearly emissions of nitrous oxide, a potent greenhouse gas, by the equivalent of as much as 130,000 tons of carbon dioxide, equal to the emissions of 14 million gallons of gasoline, according to Neville Millar, a senior researcher at Michigan State University (MSU) and first author of the published paper.

“Our study is the first to isolate the effect of multiple nitrogen fertilizer rates on nitrous oxide emissions in wheat in the tropics or sub-tropics,” Millar said. “It shows that applying fertilizer to wheat at higher than optimal economic rates results in an exponential increase in nitrous oxide emissions.”

Yaqui Valley wheat farming conditions and practices are similar to those of huge wheat cropping expanses in China, India, and Pakistan, which together account for roughly half of worldwide nitrogen fertilizer use for wheat, according to study co-author Iván Ortíz-Monasterio, a wheat agronomist at the International Maize and Wheat Improvement Center (CIMMYT), whose Yaqui Valley experiment station was the site of the reported research.

“The recommendations are thus globally relevant and represent a potential triple win, in the form of reduced greenhouse gas emissions, higher income for farmers and continued high productivity for wheat cropping,” Ortíz-Monasterio said.

Measuring nitrous oxide after nitrogen fertilizer applications in spring durum wheat crops during two growing seasons, Millar and an international team of scientists found an exponential increase in emissions from plots fertilized at greater than economically-optimal rates—that is, when the extra nitrogen applied no longer boosts grain yield.

They also found that grain quality at the economically optimal N rates was not impacted and exceeded that required by local farmer associations for sale to the market. They examined five different nitrogen fertilizer dosages ranging from 0 to 280 kilograms per hectare.

“In our study, the highest dosage to get optimum wheat yields was 145 kilograms of nitrogen fertilizer per hectare in the 2014 crop,” said Millar. “Yaqui Valley farmers typically apply around 300 kilograms. The wheat crop takes up and uses only about a third of that nitrogen; the remainder may be lost to the atmosphere as gases, including nitrous oxide, and to groundwater as nitrate.”

Promoting profitable, climate-friendly fertilizer use

Farmers’ excessive use of fertilizer is driven largely by risk aversion and economic concerns, according to Ortíz-Monasterio. “Because crops in high-yielding years will require more nitrogen than in low-yielding years, farmers tend to be optimistic and fertilize for high-yielding years,” said Ortíz-Monasterio. “At the same time, since farmers don’t have data about available nitrogen in their fields, they tend to over-apply fertilizer because this is less costly than growing a crop that lacks the nitrogen to develop and yield near to full potential.”

Ortíz-Monasterio and his partners have been studying and promoting management practices to help farmers to use fertilizer more efficiently and take into account available soil nitrogen and weather. This technology, including Greenseeker, a handheld device that assesses plant nitrogen needs, was tested in a separate study for its ability to advise farmers on optimal rates of fertilizer use.

“Sensing devices similar to Greenseeker but mounted on drones are providing recommendations to Yaqui Valley farmers for wheat crops grown on more than 1,000 acres in 2017 and 2018,” Ortiz-Monasterio notes.

Part of a research partnership between CIMMYT and MSU’s W.K. Kellogg Biological Station (KBS) Long-Term Ecological Research program to reduce greenhouse gas impacts of intensive farming, a key aim of the present study was to generate new emission factors for Mexican grain crops that accurately reflect nitrous oxide emissions and emission reductions and can be used in global carbon markets, according to Millar.

“The emission calculations from our work can be incorporated by carbon market organizations into carbon market protocols, to help compensate farmers for reducing their fertilizer use,” he said.

“This study shows that low emissions nitrogen management is possible in tropical cereal crop systems and provides important guidance on the optimal levels for large cropping areas of the world,” said Lini Wollenberg, an expert in low-emissions agriculture for the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), which helped fund the research. “With these improved emission factors, countries will be able to better plan and implement their commitments to reducing emissions.

CIUDAD OBREGÓN, Mexico (CIMMYT) – As more than 200 wheat science and food specialists from 34 countries gathered in northwestern Mexico to address threats to global nutrition and food security, 9 outstanding young women wheat scientists among them showed that this effort will be strengthened by diversity.

Winners of the Jeanie Borlaug Laube Women in Triticum (WIT) Early Career Award joined an on-going wheat research training course organized by the International Maize and Wheat Improvement Center (CIMMYT), 21-23 March.

“As my father used to say, you are the future,” said Jeanie Borlaug Laube, daughter of the late Nobel Peace Prize laureate, Dr. Norman E. Borlaug, and mentor of many young agricultural scientists. Speaking to the WIT recipients, she said, “You are ahead of the game compared to other scientists your age.”

Established in 2010 as part of the Delivering Genetic Gain in Wheat (DGGW) project led by Cornell University, the WIT program has provided professional development opportunities for 44 young women researchers in wheat from more than 20 countries.

The award is given annually to as many as five early science-career women, ranging from advanced undergraduates to recent doctoral graduates and postdoctoral fellows. Selection is based on a scientific abstract and statement of intent, along with evidence of commitment to agricultural development and leadership potential.

Women who will change their professions and the world

Weizhen Liu, a 2017 WIT recipient and postdoctoral researcher at Cornell University, is applying genome-wide association mapping and DNA marker technology to enhance genetic resistance in tetraploid and bread wheat to stripe rust, a major global disease of wheat that is quickly spreading and becoming more virulent.

“I am eager to join and devote myself to improving wheat yields by fighting wheat rusts,” said Liu, who received her bachelors in biotechnology from Nanjing Agricultural University, China, in 2011, and a doctorate from Washington State University in 2016. “Through WIT, I can share my research with other scientists, receive professional feedback, and build international collaboration.”

Mitaly Bansal, a 2016 WIT award winner, currently works as a Research Associate at Punjab Agricultural University, India. She did her PhD research in a collaborative project involving Punjab Agricultural University and the John Innes Centre, UK, to deploy stripe and leaf rust resistance genes from non-progenitor wild wheat in commercial cultivars.

“I would like to work someday in a position of public policy in India,” said Bansal, who received the Monsanto Beachell-Borlaug scholarship in 2013. “That is where I could have the influence to change things that needed changing.”

Networking in the cradle of wheat’s “Green Revolution”

In addition to joining CIMMYT training for a week, WIT recipients will attend the annual Borlaug Global Rust Initiative (BGRI) technical workshop, to be held this year in Marrakech, Morocco, from 14 to 17 April, and where the 2018 WIT winners will be announced.

The CIMMYT training sessions took place at the Norman Borlaug Experiment Station (CENEB), an irrigated desert location in Sonora State, northwestern Mexico, and coincided with CIMMYT’s 2018 “Visitors’ Week,” which took place from 19 to 23 March.

An annual gathering organized by the CIMMYT global wheat program at CENEB, Visitors’ Week typically draws hundreds of experts from the worldwide wheat research and development community. Participants share innovations and news on critical issues, such as the rising threat of the rust diseases or changing climates in key wheat farmlands.

Through her interaction with Visitors’ Week peers, Liu said she was impressed by the extensive partnering among experts from so many countries. “I realized that one of the most important things to fight world hunger is collaboration; no one can solve food insecurity, malnutrition, and climate change issues all by himself.”

A strong proponent and practitioner of collaboration, Norman E. Borlaug worked with Sonora farmers in the 1940-50s as part of a joint Rockefeller Foundation-Mexican government program that, among other outputs, generated high-yielding, disease-resistant wheat varieties. After bringing wheat self-sufficiency to Mexico, the varieties were adopted in South Asia and beyond in the 1960-70s, dramatically boosting yields and allowing famine-prone countries to feed their rapidly-expanding populations.

This became known as the Green Revolution and, in 1970, Borlaug received the Nobel Peace Prize in recognition of his contributions. Borlaug subsequently led CIMMYT wheat research until his retirement in 1979 and served afterwards as a special consultant to the Center.

When a new, highly virulent race of wheat stem rust, Ug99, emerged in eastern Africa in the early 2000s, Borlaug sounded the alarm and championed a global response that grew into the BGRI and associated initiatives such as DGGW.

“This is just a beginning for you, but it doesn’t end here,” said Maricelis Acevedo, a former WIT recipient who went on to become the leader of DGGW. Speaking during the training course, she observed that many WIT awardees come from settings where women often lack access to higher education or the freedom to pursue a career.

“Through WIT activities, including training courses like this and events such as Visitors’ Week and the BGRI workshop,” Acevedo added, “you’ll gain essential knowledge and skills but you’ll also learn leadership and the personal confidence to speak out, as well as the ability to interact one-on-one with leaders in your field and to ask the right questions.”

CIMMYT is the global leader in publicly-funded maize and wheat research and related farming systems. Headquartered near Mexico City, CIMMYT works with hundreds of partners throughout the developing world to sustainably increase the productivity of maize and wheat cropping systems, thus improving global food security and reducing poverty. CIMMYT is a member of the CGIAR System and leads the CGIAR Research Programs on Maize and Wheat and the Excellence in Breeding Platform. The Center receives generous support from national governments, foundations, development banks and other public and private agencies.

Funded by the Bill & Melinda Gates Foundation and the UK’s Department for International Development (DFID) under UK aid, the DGGW project aims to strengthen the delivery pipeline for new, disease resistant, climate-resilient wheat varieties and to increase the yields of smallholder wheat farmers.

 

First blast resistant, biofortified wheat variety released in Bangladesh

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.

Asian scientists join cross-continental training to restrain wheat blast disease

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 groups 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). “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.

ISLAMABAD, Pakistan (June 30, 2017) – Farmers in Pakistan are eagerly adopting a nutrient-enhanced wheat variety offering improved food security, higher incomes, health benefits and a delicious taste.

Known as Zincol and released to farmers in 2016, the variety yields harvests as high as other widely grown wheat varieties, but its grain contains 20 percent more zinc, a critical micronutrient missing in the diets of many poor people in South Asia.

Due to these benefits and its delicious taste, Zincol was one of the top choices among farmers testing 12 new wheat varieties in 2016.

“I would eat twice as many chappatis of Zincol as of other wheat varieties,” said Munib Khan, a farmer in Gujar Khan, Rawalpindi District, Punjab Province, Pakistan, referring to its delicious flavor.

Khan has been growing Zincol since its release. In 2017, he planted a large portion of his wheat fields with the seed, as did members of the Gujar Khan Seed Producer Group to which he belongs.

The group is one of 21 seed producer associations established to grow quality seed of new wheat varieties with assistance from the country’s National Rural Support Program (NRSP) in remote areas of Pakistan. The support program is a key partner in the Pakistan Agricultural Innovation Program (AIP), led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the U.S. Agency for International Development.

“Over the 2016 and 2017 cropping seasons, 400 tons of seed of Zincol has been shared with farmers, seed companies and promotional partners,” said Imtiaz Muhammad, CIMMYT country representative in Pakistan and a wheat improvement specialist.

Activating the gene power in seeds to boost wheat’s climate resilience

As part of varied approaches at the International Maize and Wheat Improvement Center (CIMMYT) to unleash the power of wheat biodiversity, researchers from India and Mexico have been mobilizing native diversity from ancestral versions of wheat and related grasses to heighten the crop’s resilience to dryness and heat—conditions that have held back wheat yields for several decades and will worsen as earth’s climate changes. Now their results are beginning to reach breeders worldwide.

DINAJPUR, Bangladesh (February 17,2017)- Wheat blast, a devastating fungal disease that appeared in South Asia for the first time in 2016, was the focus of a surveillance workshop in Bangladesh where international experts trained 40 top wheat pathologists, breeders, and agronomists from Bangladesh, India and Nepal.

The two-week program, “Taking action to mitigate the threat of wheat blast in South Asia: Disease surveillance and monitoring skills training,” was held at the Bangladesh Agricultural Research Institute (BARI) Wheat Research Center (WRC) in Dinajpur, Bangladesh, February 4-16, 2017.

Wheat researchers from BARI, Cornell University, the International Maize and Wheat Improvement Center (CIMMYT), Kansas State University (KSU), and the Bangladesh Agricultural University (BAU) led the workshop, training participants to recognize, monitor, and control wheat blast.

Advice for India’s rice-wheat farmers: Put aside the plow and save straw to fight pollution

By Mike Listman/CIMMYT 

ths

The Turbo Happy Seeder allows farmers to sow a rotation crop directly into the residues of a previous crop—in this case, wheat seed into rice straw—without plowing, a practice that raises yields, saves costs and promotes healthier soil and cleaner air.

EL BATAN, Mexico (November 28,2016) – Recent media reports show that the 19 million inhabitants of New Delhi are under siege from a noxious haze generated by traffic, industries, cooking fires and the burning of over 30 million tons of rice straw on farms in the neighboring states of Haryana and Punjab.

However, farmers who rotate wheat and rice crops in their fields and deploy a sustainable agricultural technique known as “zero tillage” can make a significant contribution to reducing smog in India’s capital, helping urban dwellers breathe more easily.

Since the 1990s, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been working with national partners and advanced research institutes in India to test and promote reduced tillage which allows rice-wheat farmers of South Asia to save money, better steward their soil and water resources, cut greenhouse gas emissions and stop the burning of crop residues.

The key innovation involves sowing wheat seed directly into untilled soil and rice residues in a single tractor pass, a method known as zero tillage. Originally deemed foolish by many farmers and researchers, the practice or its adaptations slowly caught on and by 2008 were being used to sow wheat by farmers on some 1.8 million hectares in India.

Click here to read more about how scientists and policymakers are promoting the technique as a key alternative for residue burning and to help clear Delhi’s deadly seasonal smog.

 

 

Deadly disease wheat blast reaches South Asia

By Mike Listman/CIMMYT

EL BATAN, Mexico (April 7,2016)- One of the most fearsome and intractable wheat diseases in recent decades is wheat blast, caused by the fungus Magnaporthe oryzae.

First sighted in Brazil in 1985, blast is widespread in South American wheat fields, affecting as much as 3 million hectares in the early 1990s and seriously limiting the potential for wheat cropping on the region’s vast savannas.

EL BATAN, Mexico (December 18,2016)- 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.

Jat’s research on conservation agriculture (CA) – sustainable and profitable agriculture that improves livelihoods of farmers via minimal soil disturbance, permanent soil cover, and crop rotations – has guided improvements in soil and environmental health throughout South Asia. His work has led to policy-level impacts in implementing CA practices such as precision land leveling, zero tillage, direct seeding, and crop residue management, and he has played a key role in building the capacity of CA stakeholders throughout the region.

Sustainable innovation, including climate-smart agriculture, were a major theme at the COP21 climate talks .
