As a fast growing region with increasing challenges for smallholder farmers, Asia is a key target region for CIMMYT. CIMMYTâs 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.

El BATAN, Mexico (CIMMYT) â International scientists are on high alert as they develop tactics to fight a deadly wheat disease that has emerged in Bangladesh, affecting a large portion of the countryâs wheat growing area.
Wheat blast, first identified in Brazil in 1985 and widespread throughout South America, deforms grain, causing it to bleach, shrivel and shrink. At its worst, the fast-moving disease can decimate a crop, leading to the urgent need for a multi-pronged approach to fight it.
The recent appearance of the disease, which is caused by the plant fungus pathogen Magnaporthe oryzae, in six districts in southern Bangladesh is estimated to have affected 15 percent of the countryâs total wheat growing area of 436,000 hectares (1.08 million acres).
âWe need to fight this disease on various fronts â both in the short and long term,â said Etienne Duveiller, principal scientist and wheat pathologist with the International Maize and Wheat Improvement Center (CIMMYT), adding that strategies include preventing the distribution of infected seed, sowing seed at designated optimal times, introducing foliar spray of triazole fungicides and developing disease-resilient seed.
âItâs paramount that infected seeds are identified and that seeds are sown at the best time to avoid rains at the sensitive stage when wheat plants develop the spike where grains form, but weâve also been working to identify resistant genetic materials â germplasm â for use in developing new varieties, a vital part of the longer term fight against the disease,â he said.
CIMMYT scientists are working with national agriculture programs on this work, setting up germplasm exchanges and testing genotypes in hot spot areas where the disease occurs, Duveiller said, adding that a smallholder farmer in one of the worst-hit areas said he expected to harvest 80 percent less wheat as a result of the disease. The problem compounds over time because farmers keep seed and replant it in subsequent years.
Scientists believe wheat blast spreads by various means, including airborne distribution, from crops planted in rotation with wheat and sexual hybridization.
âWeâre not sure what the potential scale of wheat blast spread might be because weâre still trying to understand how it survives from wheat crop to wheat crop, we urgently need investments to understand it,â said Hans Braun, director of CIMMYTâs Global Wheat Program.
âIt takes only a few days from the first symptoms occurring until major damage is caused by the fungus,” he added. “This short window makes chemical interventions difficult and prophylactic application of fungicides is too expensive for smallholder farmers. Breeding resistant varieties is the best and possibly the only option to control the disease in the long term.â

NEW DELHI (CIMMYT) — Rice-wheat rotation is practiced by farmers on over 13 million hectares of farmland in South Asia, providing the primary source of food security in the region. However, climate change is projected to have a huge impact and reduce agricultural production 10 to 50 percent by 2050. Complex and local impacts from climate change and other challenges require solutions to risks that can be readily-adapted. Representatives from Bayer Crop Science recently visited the International Maize and Wheat Improvement Center (CIMMYT) offices in India to discuss the potential for developing jointly managed sustainable approaches and technologies to address such challenges.
Sustainable intensification, which involves such conservation agriculture practices as minimal soil disturbance, permanent soil cover and the use of crop rotation to increase profits, protect the environment, maintain and boost yields, is a potential solution that has worked to address the impact of climate change in South Asia. Such practices contribute to improved soil function and quality, which can improve resilience to climate variability.
âSystems research with conservation agriculture practices like direct seeded rice, no-till wheat and recycling crop residues have shown tremendous potential to address the challenges of water and labor scarcity, conserve natural resources and lower the environmental footprint of South Asiaâs food bowl,â said M.L. Jat, CIMMYT senior cropping systems agronomist and the South Asia coordinator for the CGIAR Research Program on Climate Change, Agriculture and Food Security, collaboratively managed by the CGIAR consortium of international agricultural researchers.
During the Bayer meeting, challenges and opportunities were identified for direct seeded rice — which requires less labor and tends to mature faster than transplanted crops — and sustainable intensification programs throughout South Asia, particularly in India. Discussions were based on the success of other CIMMYT-Bayer collaborations across South Asia that aim to address agricultural challenges through sustainable intensification — including direct seeded rice — quantifying mitigation potential of conservation agriculture-based management in rice-wheat rotation and smart farm mechanization to make farm management more efficient and productive.
Moving forward, CIMMYT and Bayer will focus on agricultural systems research to ensure even more effective interventions with higher yields, collaborate to develop new sustainable technology and increase uptake throughout the region. Sustainable intensification practices are expected to continue to grow in the region thanks to these and other collaborations, along with the advent of technological advancements and increased adoption.

Bayer representatives at the meeting included: Hartmut van Lengerich, head of cereals and fungicides; Juergen Echle, global segment manager of rice herbicides; Christian Zupanc, global segment manager of rice fungicides; Mahesh Girdhar, global crop manager of rice and Rajvir Rathi, vice president of public and government affairs. CIMMYT representatives included: Tek Sapkota, mitigation specialist; Balwinder Singh, crop modeling specialist and Alwin Keil, senior economist.

SINDHULPALCHOWK, Nepal (BGRI) — Farming the terraced hillsides above the Indrawati River Valley of Nepal, Nabaraj Sapkota and his wife Muthu Dei experience the impacts of climate change on an almost daily basis. Erratic rains make planting difficult. Warm, misty conditions and prolonged winter temperatures increase the incidence of wheat rusts that reduce yield. Unpredictable hailstorms flatten wheat and rice before they can be harvested.
âWhen we need rain, there is no rain. And when we donât need rain, there is plenty of rain,â says Nabaraj. âWe used to only have rain from May through July, now we have rain and mist from November.â
Khim lal Bastola grows wheat, maize and rice in rotation and sustains four generations in his 12-person household near Pokhara. âThe change is obvious: man produces something with his hard labor but strong winds and hailstorms destroy it,â he said.
âThe climate change scenario for Nepal â where temperature are likely to increase and precipitation is likely to be more erratic â will disproportionally affect smallholder farmers,â said Dhruba Thapa, a senior scientist with the Nepal Agricultural Research Council. âFor Nepal, the cost of not adapting to climate change will be high.â
Like many farmers in Nepal, Bastola and the Sapkotas need technical assistance to help them adapt to climate change. They eagerly soak up the education offered by people like Thapa, Sarala Sharma, and Sunita Adhibari, NARC scientists who distribute disease resistant varieties of wheat and help farmers learn to identify diseases.
Scientists and farmers also soak up training from the Borlaug Global Rust Initiative (BGRI), and specialists like Dave Hodson, a wheat surveillance specialist with CIMMYT, who shows them how to scout for wheat rust and upload data into the global RustTracker monitoring system.
FARMING PERVASIVE BUT DIFFICULT IN NEPAL
Farming in Nepal is hard, backbreaking labor predominantly done by hand in fields rarely more than one-quarter of an acre in size. Men plow the small plots on the terraced hillsides with oxen. Women break up the clods with heavy adzes. Although rarely above subsistence level, small farms are of vital importance in sustaining the multi-generational communities scattered throughout the Himalayas in the high hills to the north, the temperate mid-hills, and the subtropical terai to the south.
The livelihoods of more than 75 percent of the people in Nepal are based on agriculture and forestry, and almost 65 percent of the agriculture is rainfed, Nepal is among the 25 nations in the world with the lowest GDP per person and also ranks among the 25 with the greatest decrease in forested land. Rural populations are heavily clustered in river basins whose annual monsoon-fed flood cycles are likely to be exacerbated by warming. Deforestation adds to the problem, intensifying flooding and contributing to the likelihood of landslides.
HELPING FARMERS ADAPT TO CLIMATE CHANGE
Using disease resistant and improved seeds, and adopting different planting and harvesting calendars helps farmers adapt to climate change.
In Chhampi, north of Kathmandu, Krishna Bahadur Ghimire and the local farmersâ cooperative of which he is president, are now producing improved rice, wheat and maize on 140 ropanis of land. Ghimere supplies beans, rice, eggplant, soybeans, wheat and vegetable seeds to his neighbors. He started farming on one ropani of land (~ 500 sq.m) in 1997 but switched to the seed business when he found himself having to drive two hours to Kathmandu to get the improved varieties he needed.
âOur local varieties were not climate smart. We went to Kathmandu to get improved seeds from the Nepalese Agricultural Research Center because their seeds are more disease resistant, higher yielding, and higher quality,â said Ghimire, who has worked with Thapa for 11 years. Â âNew varieties are less lodging and scattering during storms and high winds than the local ones.â
âFarmers need climate smart crops that have been improved for yield and disease resistance, but they also need seeds adapted for variable weather conditions whether we have drought or excess rainfall,â said Thapa. âNARC screens many lines and then provides seeds of promising lines to farmers for participatory variety selection trials, like with Ghimireâs group.â
Naparaj, the Sindhulpalchowk farmer, initially received 300 grams of seven varieties of improved wheat from Thapa. âI was thinking how I could uplift them (my neighbors),â said Naparaj. âI thought to myself, the lives of these people must be uplifted through improved seeds which would give them good production. We used to get one muri (~3.5 liters or 70 kg) of wheat per one ropani (~ 500 sq.m.). Now we are threshing three or four times more. It is a huge profit.â
Ghimereâs 25-year-old nephew Saroj Kumar Bista, speaks of another problem affecting farmers that requires gender-sensitive initiatves. âMany young men are going to the Middle East to work and not moving into the farming sector,â he said.
Nowhere is this more evident than in Godhavari, where Manju Khavas, Radha Basnet and Janaki Silwalâs sons have gone to the Middle East or Japan to work. Their husbands work off the farm, leaving them in charge. âAt first we were overwhelmed,â said the 52-year-old Khavas. âWe could not find someone to dig the fields. Now it is easier because of the handheld tractor.â
Thapa introduced improved eight or nine varieties of wheat to their community as well as agronomic practices like planting in rows, incorporating manure for fertilizer, and using handheld tractors (similar to heavy duty rototillers).
How does Khavas count improvement? âWhen we were 7 or 8 members in the family, the produce of this land was not enough. Now the produce is enough for 13 to 14 people,â she said. Wheat yields are so improved that she and her friends want a wheat threshing machine so they donât have to thresh the greater quantities by hand.
Although the women said they have yet to âevaluateâ climate change, they noted the âenvironment has been spoilt.â
âDuring the harvesting season of the wheat, we suffer from the fear of rain,â said Khavas. âHailstorms also scare us. The moment the wheat becomes yellow, we begin to feel afraid whether we will be able to harvest it or not. And then when the wheat is harvested amid the fear of rain, in the paddy rice planting time, there is no rain.â
MORE TRAINING FOR CLIMATE CHANGE ADAPTATION
Dave Hodson, a surveillance expert with CIMMYT and the BGRI, travels to countries like Nepal to train scientists on using handheld tablets to scout for disease and input data into global disease tracking and monitoring systems that can help to predict disease outbreaks.
Since 2008, the BGRI has held five 2-week training sessions on the âArt and Science of Rust Pathology and Wheat Breedingâ in Asia for scientists in the South Asian Association for Regional Cooperation (SAARC), including scientists from Nepal, India, Pakistan, Afghanistan, Bangladesh and Bhutan. The course is slated to be on-line this summer.
Nepalese farmers lack understanding of meteorological data and how to reduce risks in agriculture and farming. Sushila Pyakurel, who works with ICDO Lalitpur, has helped initiate Climate Field Schools in Nepal where farmers learn the effects of climate change, identifying crops most suitable to grow, seed selection, scheduling farm operations/farm management practices, and adaptation strategies/methodologies.
One of the new areas of expansion for the BGRI is the new Delivering Genetic Gain in Wheat project, a $24M effort funded by the Bill & Melinda Gates Foundation to make wheat for smallholder farmers around the world more heat tolerant and disease resistant in the face of climate change. It builds on the successes of the 2008-2015 Durable Rust Resistance in Wheat project, which initiated and funded the SAARC training courses.
DEDICATION: April 25, 2016: For smallholder farmers in Nepal, the challenges of climate change are disastrous enough. A 7.8 magnitude earthquake devastated Nepal on 25 April 2015, less than one month after the Borlaug Global Rust Initiative team visited. More than 9,000 people died and almost 900,000 homes were destroyed. Some of the hardest hit areas were Sindhulpalchowk and Chhampi. This Earth Day blog is dedicated to the resilient farmers of Nepal. It is the BGRIâs sincerest hope that their families are well on their way to recovery.

CIMMYT Country Representative Imtiaz, Muhammad during the presentation of a working paper on ICT in agricultural extension said, âThis new era of technology is leading to new horizons in agricultural research. The trends indicate powerful impact of information communication technology on improving the farmerâs productivity and these innovative practices will ultimately improve the Pakistani agricultural sector.â
Praising the efforts of AIP, Federal Secretary for National Food Security and Research Abid Javed pointed out that the continuous support of the American people is reshaping Pakistanâs agricultural sector, particularly farmers.
“ICT, like never before, offers us unprecedented opportunities to connect people and make useful information available to poor farmers. We have to find out how to better turn that potential into reality,” said Mark Bell, leader of AIPâs e-Pak Ag.

As PARC Chairman Nadeem Amjad indicated, today the use of ICT is essential and AIPâs efforts will make it easy to convey relevant and credible information to extension staff and, through them, to farmers.
The United States is committed to working hand in hand with Pakistan to develop and modernize the agricultural sector. As a global center of excellence in the improvement of maize and wheat systems, CIMMYT has maintained a long and highly productive relationship with the Pakistani government and national partners, with the invaluable support of U.S. government agencies. AIPâs E-Pak Ag activities are capturing science and research innovations led by UC Davis, which has a rich history of working with and strengthening research, education and extension programs around the world.
Launched in 2013, the USAID-funded Agricultural Innovation Program for Pakistan (AIP) works to increase agricultural productivity and incomes by promoting and disseminating modern practices in the cereal and cereal systems (wheat, maize and rice), livestock, fruit, and vegetable sectors; enhancing the capacity of agricultural scientists and researchers through short-term and long-term training such as M.Sc. and Ph.D. scholarships at U.S. land grant universities; establishing Provincial Agricultural Research for Development (AR4D) Boards to support expansion of provincial linkages to national, regional and international communities through a mechanism of coordination; and improving agricultural growth and research in Pakistan through a Competitive Grants System. Project management is vested in a unique consortium of Consultative Group for International Agricultural Research (CGIAR) centers, US land grant universities, non-CGIAR centers, and the Pakistan Agricultural Research Council (PARC), led by the International Maize and Wheat Improvement Center (CIMMYT).

ISLAMABAD â The maize sector in Pakistan is benefiting from an upsurge in investments leading to new varieties from the International Maize and Wheat Improvement Center (CIMMYT) that have the potential to increase production, enhance nutrition and strengthen national industry.
Maize is the third most important cereal crop in Pakistan, which at a production rate of four tons per hectare, has one of the highest national yields in South Asia. Maize productivity in Pakistan has increased almost 75 percent from levels in the early 1990s due to the adoption and expansion of hybrid maize varieties. The crop is cultivated both in spring and autumn seasons and grows in all provinces throughout the country.
However, the lack of a strong national seed system has caused Pakistan to import more than 85 percent of its hybrid maize seed at a cost averaged about $50 million annually since 2011. When coupled with other factors including a limited source of seed providers and non-relaxation of duties on imported seed, this causes the unit price of hybrid maize seed to be the most expensive in South Asia.
PROJECTÂ BOOSTSÂ SEED
A project launched in 2013, CIMMYTâs Agricultural Innovation Program (AIP) funded by the U.S. Agency for International Development (USAID), led to a large-scale evaluation of maize varieties, which have since resulted in more than 1,000 diverse genotypes tested for favorable traits across Pakistan. Currently, 20 public- and private-sector companies are partnering with CIMMYT to test new varieties and deploy locally-adapted products.

In just two years since the launch of this initiative, more than 80 CIMMYT-derived hybrids and open pollinated varieties of maize have been identified and adapted to diverse ecologies in Pakistan. In the first phase, CIMMYT allocated 49 maize products for registration, commercial release, further seed scale-up and delivery in the target geographies in Pakistan. This maize germplasm was sourced from CIMMYTâs regional maize breeding hubs mainly from Colombia, Mexico and Zimbabwe. With the help of national partners, these improved varieties are being put in the hands smallholder farmers throughout the country.
Seed businesses in Pakistan now have the leverage to run a competitive domestic market for maize seed, thanks to these new varieties. Diverse new lines are also more nutritious, mature earlier and are more tolerant to drought. They can also be delivered at an affordable price which is a huge step forward compared to the limited options smallholder farmers had before AIP started.
Biofortification, or the enhancement of the nutritional value of a crop, has been a cornerstone of CIMMYTâs work in developing improved varieties. Quality Protein Maize (QPM) was the first new hybrid product to reach farmers in Pakistan. Â Demonstration seeds from the first two biofortified maize hybrids in Pakistan were officially distributed to farmers this February by the National Agricultural Research Center (NARC), one of the national partners to AIP. The two QPM hybrids, originally from CIMMYT-Colombia, will reach about 300 farmers this season and further distribution is expected by 2017.

âWe know how precious (CIMMYTâs) parental seeds are,â said Muhammad Hashim Popalzai from Pakistanâs Ministry of National Food Secuirity and Research. Â âAt times it will take up to eight years to develop inbred lines and another 3-4 years to constitute hybrid seeds, however, we are getting them easily under the AIP program.â
Although developing new seeds takes time, the benefits could make a huge contribution to Pakistanâs economy, health and livelihoods for farmers across the country.
âThese parental seeds will help us to produce the seed locally,â said Faiysal Hayat, deputy manager of seed company Jullundur Private Ltd., adding that they will also âenable us to provide quality seed at an affordable price to farmers.â
In reviewing the progress of AIP maize activities, Abdu Rahman Beshir, CIMMYTâs maize improvement and seed systems specialist said: âThe overwhelming interest and collaborations from public-private stakeholders of Pakistanâs maize sector are the main thrust for CIMMYTâs maize varietal deployment drive in Pakistan.â
Subsequent activities in quality seed production and enhanced product positioning will further reinforce the encouraging gains of AIP which aims to have a vibrant maize seed system in Pakistan, according to Beshir.
NEW DELHI (CIMMYT) — Ram Kanwar Malik, senior agronomist at the International Maize and Wheat Improvement Center (CIMMYT), has received the 2015 Derek Tribe Award from the Crawford Fund, for his âoutstanding contributions to making a food secure world by improving and sustaining the productivity of the rice-wheat system of the northwestern and eastern Indo-Gangetic Plains.”
The award recognizes Malikâs more than 30 years of work in agricultural research and development dedicated to improving the livelihoods of millions of small and marginal farmers in India. He led the development of a management solution for herbicide resistant Phalaris minor, a major wheat weed. This pioneering research is estimated to have prevented farmers from losing nearly 1 million hectares (2.5 million acres) of wheat and to have raised wheat productivity in the grain basket states of Haryana and Punjab, between 1992 and 2000.
âFor developing countries like India where farmers are smallholders and marginalized and investment in research is low, the development of new technologies and the process of delivery are inseparable,â said Malik, highlighting his life-long passion for understanding the need for farmer participation in research. âIn fact, a top-down approach could put up barriers to the adoption of new technologies. Listening to farmers and tailoring technologies to serve their needs thus become paramount.â
Malikâs collaborative work with national and international partners and farmer participatory approaches has also led to achievements in the adoption and spread of climate-resilient technologies such as zero-tillage, laser land leveling and direct-seeded rice, as well as policy changes at the government level.
Recently, Malik played an instrumental role in advocating for the early sowing of wheat in Bihar, which can double a farmerâs yield and avoid crop failure caused by higher temperatures and an early summer. Malikâs team has created a network of more than 2,000 service providers to provide easy access for smallholder farmers to machinery and modern farming technologies.

NEW DELHI (CIMMYT) â India’s Krishi Unnati Mela national agriculture fair, which was hosted by Indiaâs 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 countryâs 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 Indiaâs 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 âAn integrated approach to maintaining cereal productivity under climate changeâ argue that cropping systems could become more resilient in the face of climate change through better coordination. Needs include characterizing target agro-ecosystems, Â standardization of experimental protocols, comparative biology across cereals (and possibly other crops)Â and data sharing.
Better integration of research effort across the major cereal crops â including wheat, rice, maize, pearl millet and sorghum â 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.
âMost of the big challenges in crop improvement are transnational, therefore a better globally integrated research effort is a triple win scenario,â according to  Matthew Reynolds, head of wheat physiology at the International Maize and Wheat Improvement Center (CIMMYT), and lead author of the paper. âItâs more efficient since duplication of effort is reduced, itâs synergistic since we learn simultaneously from multiple crops and environments [or cropping systems], and itâs faster to achieve impacts because outputs are disseminated more broadly.â
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 â working across the five crops â 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.
âThis paper has provided a baseline about what needs to be done,â said O.P. Yadav, director of the Central Arid Zone Research Institute at the Indian Council of Agricultural Research. âIt 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.â

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).
âThis is the right time to assess AIPâs 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,â 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 Bangladeshâs agriculture minister and member of Parliament Begum Matia Chowdhury and Secretary of Agriculture Mohammad Moinuddin Abdullah, where CIMMYTâs 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 Instituteâs (BARI) research station in Jessore and farmersâ 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 organizationâs 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)Â 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 farmersâ income, helped crops sustain or adapt to heat and water stresses, and reduced agricultureâs 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 âterminal heat effect.â 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 â 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 farmersâ 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 âTurbo Happy Seeder,â 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.

NEW DELHI — The International Maize and Wheat Improvement Center (CIMMYT) Director General Martin Kropff presented the organizationâs draft strategy with its unifying vision of âOne CIMMYTâ at the staff session in the Delhi office during his India visit from 24 February to 3 March. Kropff highlighted that CIMMYTâs 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: âMaize & Wheat Science for Improved livelihoods.â

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 âwill 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 BISAâs 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 wheatâs 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 wheatâs 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.
âThe landraces, known as Creole wheats, were brought to Mexico as early as the 16th Century,â said Singh, who also credited the study to MasAgro, a long-term rural development project between Mexico and CIMMYT. âWheat 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).â
Heat can wreak havoc with wheatâs 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.
âTypically, massive seed collections constitute âblack boxesâ that scientists have long believed to harbor useful diversity but whose treasures have remained frustratingly inaccessible,â Singh explained. âNew technology is helping to change that. As part of MasAgroâs âSeeds of Discovery Component,â 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 âalleles.â â
According to Kevin Pixley, director of CIMMYTâs 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. âThe 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.â
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 worldâs poorer regions.
