MEXICO CITY (CIMMYT) – While genetically modified (GM) foods continue to be a topic of debate in much of the developed world, few studies have focused on consumers’ acceptance of GM food in developing countries.

A new study from researchers at the International Maize and Wheat Improvement Center (CIMMYT) used a comprehensive primary dataset collected from 320 consumers in 2013 from Pakistan to analyze the determinants of consumer acceptability of GM foods in the country.

The researchers found that GM foods were more accepted among female consumers as compared to male consumers. In addition, older consumers were more willing to accept GM food compared to young consumers. The acceptability of GM foods was also higher among wealthier households. Low price is the key factor leading to the acceptability of GM foods.

NEW DELHI (CIMMYT) – If women were given the same access to land, seed and other resources as men, they could increase yields on their farm up to 30 percent, reducing the number of hungry people in the world by 150 million. However, large gender disparities in agriculture continue to make it difficult for rural women to access resources and make their own farming decisions.

In response, the International Maize and Wheat Improvement Center (CIMMYT) and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) began initiatives to empower rural women such as campaigns to eliminate residue burning, build partnerships with local organizations and more.

Climate-smart agriculture (CSA) addresses the interlinked challenges of food security and climate change by sustainably increasing agricultural productivity, building resilience in food-production systems and reducing greenhouse gas emissions in agriculture.

In celebration of International Women’s Day, two events promoting the adoption of CSA technologies and practices among women farmers – like the GreenSeeker sensor, zero tillage farming and others – were organized in the states of Bihar and Haryana, India, representing contrasting agro-ecological and socio-economic regions.

“Linking with CIMMYT-CCAFS, I’ve learned advanced farming techniques, which support better agriculture with increased productivity and profits,” said Ms. Suman, a young farmer from Bastara village in Karnal, India. Suman’s success with climate-smart agriculture inspired women from other villages to begin practicing sustainable farming as well. Photo: CIMMYT

In Bihar, the event was held in collaboration with the Indian Council of Agricultural Research (ICAR)-Research Complex for Eastern Region, Patna and the Borlaug Institute for South Asia and was attended by 80 women farmers from climate smart villages (CSVs), areas that integrate CSA technologies and practices into village development plans, using local knowledge and expertise and supported by local institutions, to help communities adapt to and mitigate the effects of climate change.

Usha Singh, professor of home science at Dr. Rajendra Prasad Central Agriculture University, Bihar, highlighted the role of women in Bihar’s agriculture sector and their contribution to sustainable food production, nutrition and livelihoods. Singh shared home remedies to overcome malnutrition among children and women in rural areas by using their farm produce to prepare balanced diet. R.K. Asthana, animal husbandry scientist with the agricultural extension center Krishi Vigyan Kendra (KVK) in Biroli, emphasized the important role training activities for livestock management can have in improving the socioeconomic status of women in the area.

In Haryana, the event was organized at a climate smart village in Bastara, Karnal in collaboration with the ICAR-Central Soil Salinity Research Institute, which was attended by over 70 women farmers from across several villages. Women shared their experiences under CSVs, discussed ways to increase productivity and profitability, and raise awareness among other women farmers in the area.

HS Jat, CIMMYT senior scientist in Karnal, provided an overview of CIMMYT-CCAFS activities in Haryana and emphasized strengthening and formalizing women groups to enhance knowledge and increase access to resources. CIMMYT event organizers and assistant research associates Munmun Rai and Deepak Bijarniya, and assistant research scientist JM Sutaliya, collectively emphasized the positive impact of CSA interventions in India, which have built farmer resilience to climate change while increasing their productivity and incomes. Deepa Chandra and DK Gosain, program coordinators for National Dairy Research Institute’s KVK in Haryana, also spoke at the event.

Bangladesh urges $500 million in funds to intensify surface water irrigation

EL BATAN, Mexico (CIMMYT) – Most current food security projections show that staple crop production must double by 2050 to keep up with global need, which will continue to expand due to population growth and changing dietary demands.

In South Asia, where population pressures pose a significant food security challenge, yields of major cereal crops have not changed dramatically since the Green Revolution of the 1970s and 1980s. This has prompted regional governments and development practitioners to focus instead on efforts to expand double cropping – the practice of growing at least two crops per year on the same piece of land – in order to boost productivity on an annual basis.

This approach is in line with sustainable intensification techniques, which aim to boost production, rather than encroach on natural ecosystems and harm the environment by expanding farmland into limited natural areas.

Scientists with the International Maize and Wheat Improvement Center (CIMMYT) are researching how best to increase double cropping in Bangladesh, which, as South Asia’s most densely populated country, poses unique food security challenges.

In the northwest of the country, farmers already rotate at least two crops in the same field each year using groundwater irrigation to overcome drought risks during the dry winter season.

“Most development initiatives favor the use of groundwater resources for irrigation, although in Bangladesh, ground water extraction can result in high energy costs and in some areas can present a health risk due to natural arsenic contamination of groundwater,” said Timothy Krupnik, systems agronomist at CIMMYT.

“In support of government programs recommending the conjunctive use of surface water as an irrigation alternative, we investigated the available land in Bangladesh that could be reliably cropped to wheat, maize, or rice in double cropping patterns,” Krupnik said, adding that the effort resulted in a new online geospatial tool that can be used by water resource planners and policymakers to target the use of surface water in support of sustainable intensification. It helps identify surface water irrigation resources and land area most suited for double cropping and sustainable intensification.

“Using satellite data for irrigation technology targeting in Bangladesh enabled us to identify areas that are under low input and output crop production in a region with abundant surface water,” said Urs Schulthess, CIMMYT’s remote sensing scientist involved in developing the geospatial tool. “This is an example of sustainable intensification that does not deplete water resources.”

Instead of extracting water from underground aquifers, surface water irrigation involves deploying water through low-lift irrigation pumps and canal distribution networks managed by water sellers who direct water to farmers’ fields. Although Bangladesh is likely to remain largely reliant on groundwater irrigation, use of available surface water presents a low-energy and low-carbon emissions alternative in select areas of the country, Krupnik said.

The research conducted by scientists funded by the CIMMYT-led Cereal Systems Initiative for South Asia (CSISA) project, provides initial evidence to support a government of Bangladesh policy aimed at stimulating a $500 million investment in development aid from donors to help farmers transition from rice-fallow or rainfed systems to surface water irrigation and double cropping. The funds form part of an overall request for investment of over $7 billion to support agricultural development in southern Bangladesh.

After mapping rivers and freshwater canals in southern Bangladesh with the new tool, the scientists conservatively estimate that at least 20,800 of fallow and 103,000 hectares of rainfed cropland could be intensified through surface water irrigation to substantially increase cereal crop production through double cropping. These figures account for land set into non-crop reserves to limit risks of nitrate or phosphorous contamination of rivers and canals.

Groundwater irrigation techniques have been difficult to implement in the south of the country due to high energy pumping costs for groundwater, and additional challenges posed by saline shallow water tables. Currently, about 1.7 million farming households in Bangladesh simply leave cropland fallow and unproductive after the monsoon season, according to the World Bank.

By integrating the use of groundwater with lower-cost surface water irrigation, farmers could benefit from increased cropping intensity.

To evaluate potential land productivity resulting from conversion from fallow or rainfed crops to surface water irrigated maize, wheat, and rice, CIMMYT scientists measured yields produced by farmers on their own farms and in farmer-managed demonstrations implemented by the CSISA project.

The three crops are among the most important cereals grown in Bangladesh for food security and income.

Based on analysis, CIMMYT’s scientists estimate that if 25 to 75 percent of fallow or low-intensity land is converted to irrigated maize, production could increase from 10 to 14 percent or from 29 to 42 percent, respectively. Conversion to wheat could increase production from 9 percent to 10 percent or from 26 percent to 31 percent. On the other hand, rice is projected to increase only about 3 percent under such conditions.

Overall, increasing maize and wheat production through double cropping could generate revenues from $36 to $108 million each year for farmers, Krupnik said.

Breaking Ground: Akhter Ali helps transform agriculture sector in Pakistan

AkhterAliBreaking Ground is a regular series featuring staff at CIMMYT

EL BATAN, Mexico (CIMMYT) – Akhter Ali always knew he wanted to have an impact on the livelihoods of farmers in Pakistan.

“I come from a farmer family – the poverty and inequality of rural communities always disturbed me,” said Ali, who was born in Multan district, Pakistan. “I knew from a young age I wanted to do something to help my community and the rural poor throughout my country.”

Ali, an agricultural economist at the International Maize and Wheat Improvement Center (CIMMYT), is working to sustainably increase agricultural productivity and incomes for farmers through the Agricultural Innovation Program (AIP), an initiative funded by the U.S. Agency for International Development to build up the country’s agriculture sector through the development and dissemination of new agriculture technologies.

“Agriculture supports nearly half of Pakistan’s population – more than two thirds for those living in rural areas –  and accounts for over 20 percent of Pakistan’s gross domestic product” Ali said. “Strengthening this sector by connecting and addressing the needs of different actors in rural markets is key to poverty reduction and achieving food security.”

Despite the significant role of agriculture to the economy, the sector has only grown 2.8 percent in recent years due to weak market structures, resource depletion and other challenges. Ali, along with other researchers, is analyzing how maize and wheat farmers can access the best seed, technology and practices to sustainably increase crop yields across the country.

“If we want to boost farmer livelihoods, we need to change how farmers work by ensuring they know how to sustainably manage their land, water and other resources,” Ali said. “We then need to ensure that the markets in which these farmers operate are stable so that they have easier access to agricultural inputs like seed.”

Ali’s research over the past four years at CIMMYT has focused on making these goals a reality, from conducting comprehensive surveys, which are expected to help develop the durum wheat market in Pakistan, to adoption and impact studies of such sustainable technology as zero tillage machines and precision land levelers, now used by thousands of farmers throughout Pakistan.

“There are 80,000 farmers – 20 percent of which are women, whose numbers are growing – working with AIP who have adopted these new, sustainable technologies,” said Ali. In the future, Ali hopes to see his work continue to be used as a tool by policy makers, extension workers and others.

“We still face challenges with farmer access to seed, from engaging women to market constraints, so it’s critical we create policies that facilitate sustainable development in rural communities,” Ali said.

Shifting trends in Pakistan from urbanization to climate change will make it even more necessary to understand how rural communities operate in the coming years, he said, adding that policies supporting its development will be key to feeding the country and alleviating rural poverty.

Small machinery provides affordable options for women farmers in Nepal

EL BATAN, Mexico (CIMMYT) – Small-scale mechanization is becoming more important on smallholder farms in Nepal as young people, particularly men, migrate away from rural areas in large numbers, leaving women to take on even bigger responsibilities.

Some 13 million people – about 50 percent of Nepal’s population – live in the hills and mountains where most subsistence farming takes place. Women traditionally contribute more agricultural labor than men in these rural areas, typically undertaking time-consuming tasks such as weeding, harvesting, threshing and milling in addition to household chores. Two-thirds of women in Nepal are self-employed or engaged in unpaid family labor.

Nepal has the lowest ratio of men to women in all of South Asia and the proportion of rural households headed by women jumped from 15 to 25 percent between 2001 and 2011. As a result, rural women face many challenges, their potential curtailed in part due to the difficulty accessing credit. Despite a 2002 amendment to the country’s Land Act, the practice of male succession means that women only own property in a fifth of rural households.

“Almost everywhere there are changes, but maybe particularly so in the mountains,” said Scott Justice, a rural mechanization specialist with the Cereal Systems Initiative for South Asia project in Nepal (CSISA-NP), who works with smallholders as part of efforts to help improve livelihoods. “Tasks like the upkeep of terraces, plowing or service hiring are getting delayed or passed on to women, at the same time as the prices of hiring are going up.”

Following the April 2015 earthquake in Nepal, CSISA-NP was contracted by the United States Agency for International Development (USAID) to help affected farming communities recover by providing grain storage tools, farm machinery and training, reaching 33,150 earthquake-affected households.

CSISA-NP, a project led by the International Maize and Wheat Improvement Center (CIMMYT) with the International Rice Research Institute and the International Food Policy Research Institute and funded by USAID, aims to address the gender imbalance by increasing access to affordable machinery options to increase farm income while reducing drudgery for women.

An as yet unpublished study on the spread of mini-tillers has shown approximately 7,000 mini-tillers sold in hill districts, Justice said.

“A key priority for the government and projects like ours is getting owners to use the [mini-tiller] engine to power other machinery like wheat and rice threshers, mini-maize shellers, pumps and maybe even reapers and planter-seeder attachments,” said Justice.

“A small cadre of machinery importers who, along with CIMMYT’s market development efforts, are increasingly attuned to small farmers’ needs, bringing in a new generation of small and inexpensive machinery ideas and products emerging from China,” he said. “These qualities make it easier for women and their households to access and use such technologies.”

One of the technologies identified by CSISA-NP is a small, lightweight, precision hand cranked fertilizer spreader, which is growing in popularity because it can increase rice and wheat yields by 5 to 10 percent while cutting labor by half or more. CSISA has trained 150 service providers to use the fertilizer spreader, while cooperating private sector partners have imported over 500 of these spreaders in advance of the 2016-2017 wheat season.

CSISA focuses on the creation of a sustainable private machinery and service sector that serves farmers’ needs. A core group of approximately 15 to 20 (mostly) small businesses are constantly traveling and scouring the markets in China for new machinery and new ideas. One challenge is to encourage them to look more broadly in Asia for innovative scale appropriate technologies that meet the needs of both women and men in Nepal.

“Our activities are based on more than two decades of CIMMYT experience of small-scale mechanization in Nepal’s Terai area – rather than joining farmers’ experiments, we join in small and mid-sized machinery importers’ marketing experiments,” explained Justice.

CSISA is led by CIMMYT with the International Rice Research Institute and the International Food Policy Research Institute and funded by USAID. It was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems. 

Breaking Ground: Xuecai Zhang prepares future generation of crop breeders

TwitterBG8Breaking Ground is a regular series featuring staff at CIMMYT

EL BATAN (CIMMYT) — Xuecai Zhang wants to merge traditional maize breeding methods with new software and other tools to help improve farmers’ yields faster than ever.

“In the next three decades we need to increase agricultural production by 70 percent to meet projected food demand,” said Zhang, a maize genomic selection breeder at the International Maize and Wheat Improvement Center (CIMMYT). “However, crop yields, while improving, are not increasing quickly enough to meet this challenge. We must explore new methods and technologies that can speed up our crop breeding processes if we hope to feed a world with over 2.3 billion more people by 2050.”

Growing up in Henan province, China, Zhang’s mother was a teacher who instilled a love of science in him from a young age.

“I loved exploring outside and seeing how plants grew — I always wanted to know how they worked,” said Zhang. “Maize was naturally interesting to me because it’s the second most grown crop in Henan, and is becoming a very important crop in China overall.”

Zhang first arrived at CIMMYT in 2009 while completing a doctorate in applied quantitative genetics. He subsequently returned as a postdoctoral fellow in 2011 to undertake molecular breeding and coordinate CIMMYT’s maize genomic selection program.

Since his return, he has focused mainly on helping breeders and statisticians work together to create new tools that can help accelerate the breeding process through genomic selection.

“It’s crucial that as breeders, we’re able to use genomic selection in our work,” Zhang said. “Not only does it speed up the breeding process to deliver better, faster results to farmers in the field, applied well it’s also a more cost-effective option.”

Conventional plant breeding is dependent on a researcher going into the field, observing the characteristics of a plant based on how its genotype interacts with the environment, then painstakingly selecting and combining those materials that show such favorable traits such as high yield or drought resistance.  This process is repeated again and again to develop new varieties.

Genomic selection adds DNA markers to the breeder’s toolkit. After initial field evaluation breeders are able to use DNA markers and advanced computing applications to select the best plants and predict the best combinations of plants without having to wait to evaluate every generation in the field. This speeds up the development of new varieties as more cycles of selection and recombination can be conducted in a year compared with field selection alone.

The cost of hiring a human to go and collect phenotypic data for conventional breeding is increasing, while conversely the costs associated with genomic selection are getting lower as genotyping and computing technology becomes more affordable, according to Zhang.

“Breeders need to think about where the technology is pushing our field,” he said. “They will increasingly have to be versed statisticians and computer scientists to effectively apply genomic selection to their work, and I want to help ensure they have the skills and tools to make the most of the technology.”

Zhang has helped demonstrate to breeders in Latin America, Africa and Asia of the value of genomic selection by showing that the technique can improve the prediction accuracy of successful varieties in comparison to conventional breeding. He also credits joint efforts like the GOBII project, a large-scale public-sector effort supported by the Bill & Melinda Gates Foundation, to apply genomic selection techniques to crop breeding programs across the developing world, as key towards curating the necessary data for genomic breeding programs.

“In the future, I hope to continue to help build better tools for breeders to move towards genomic selection,” Zhang said. “I chose to breed maize because of the potential impact it has to help smallholder farmers globally. Compared with other crops the yield potential of maize is very high, so I want to ensure we are using the best resources available that will help maize reach its full potential.”

EL BATAN, Mexico (CIMMYT) – A scientist who has advanced the development of nutrient-rich millet and wheat varieties with higher yield potential, disease resistance and improved agronomic traits has won the 2016 Young Scientist Award for Agriculture presented by India’s Society for Plant Research.

Velu Govindan, a wheat breeder from India working with the HarvestPlus project at the International Maize and Wheat Improvement Center (CIMMYT), received the award last week for high-yielding, nutritious wheat varieties tolerant to rust diseases and climate change-induced heat and drought stress.

“I’m so honored,” said Govindan. “It’s a terrific vote of confidence for the work we’re doing at CIMMYT and through HarvestPlus to develop nutritious staple crops that significantly reduce hidden hunger and help millions of people lead better, more productive lives in the global south.”

CIMMYT scientists tackle micronutrient deficiency or “hidden hunger” by biofortifying crops to boost nutrition in poor communities where nutritional options are unavailable, limited or unaffordable. About 2 billion people worldwide suffer from hidden hunger, which is characterized by iron-deficiency anemia, vitamin A and zinc deficiency.

The wheat component of HarvestPlus, which is part of the Agriculture for Nutrition and Health program managed by the CGIAR global agricultural research project, involves developing and distributing wheat varieties with high zinc levels.

Govindan has been actively involved in the recently released wheat variety Zinc Shakthi – meaning “more power” – which has been adopted by some 50,000 smallholder farmers in India. In addition, two new varieties are projected soon to be widely adopted throughout the fertile northwestern Indo-Gangetic Plains of India.

“We’ve released ‘best bet’ varieties in India and Pakistan to ensure fast-track adoption of high zinc wheat,” Govindan said. “Farmers are adopting it, not only for its nutritional benefit, but also for its superior agronomic features like competitive yield, rust resistance and other farmer preferred traits.”

Before joining CIMMYT eight years ago, Govindan worked at the International Crops Institute for the Semi-Arid Tropics (ICRISAT), where he initiated the development of an iron-rich pearl millet called Dhanashakti – meaning “prosperity and strength” – which was commercialized in 2012 in the Indian state of Maharashtra, where it is now used by more than 100,000 smallholder farmers.

In addition to his primary responsibility of breeding nutrient-rich wheat varieties, Govindan works with the Global Wheat Program’s spring wheat breeding team at CIMMYT. The spring bread wheat program develops high yielding and climate resilient varieties, which are distributed to more than 80 countries in the wheat growing regions of the developing world.

Through its annual awards ceremony, the Society for Plant Research, which has also produced the international journal Vegetos since 1988, recognizes individual contributions from across a broad spectrum of plant-based research, including agriculture, biotechnology, industrial botany and basic plant sciences.

Pakistan releases first quality protein maize varieties

ISLAMABAD (CIMMYT) – For the first time, Pakistan will release quality protein maize (QPM) varieties for commercial consumption, which could help boost nutrition across the country where nearly half of all children are chronically malnourished.

In January 2017, Pakistan’s maize variety evaluation committee approved QPHM200 and QPHM300, two QPM hybrids, for large-scale cultivation in Pakistan. Developed by the International Maize and Wheat Improvement Center (CIMMYT) in Colombia and evaluated and selected in Pakistan by the National Agricultural Research Center (NARC), these QPM hybrids can potentially yield up to 15 tons per hectare (ha) – over three times the national average – and can be provided to farmers for less than half the price of currently imported hybrid seeds.

Maize is Pakistan’s third most important cereal following wheat and rice, producing one of the highest average grain yields in South Asia. While the majority of Pakistan’s maize is used for poultry feed, it is a major food source in Khyber Pakhtunkhwa, Gilgit Baltistan and the territories of Azad Jammu and Kashmir (AJK). These areas experience some of the highest rates of child malnutrition.

Normal maize is deficient in essential amino acids lysine and tryptophan, key protein building blocks that can’t be synthesized by human body and must be acquired from food sources. As a result, when human diets are comprised mainly of maize, consumers face a risk of malnutrition, particularly those with high protein requirements like young children, pregnant or lactating women. Conventionally bred QPM grain, which has been shown to improve nutritional status, has enhanced levels of lysine and tryptophan while the kernels have a favorable texture and flavor.

QPM was recently introduced to Pakistan through the CIMMYT-led Agricultural Innovation Program (AIP) in collaboration with national partners with support from the United States Agency for International Development. The commercialization of the two QPM hybrids was aimed at boosting nutrition by alleviating protein deficiency, particularly for low income communities where affording protein rich diets is difficult.

In addition, providing low cost feed like QPM to the poultry industry can also enhance the nutritional status of the country, an industry that is growing 8 to 10 percent annually.

“The taste of the cob is unique, it’s good quality,” said Muhammad Hafiz, a QPM grower from Pindi Bhattain area in central Punjab who participated in pre-commercialization trials of the hybrids.

The QPM hybrids were primarily selected based on their yield advantage. Farmers were open to adopting them since they performed better in many locations than normal commercial hybrids. The added benefit of quality protein will also help promote the hybrids while combating malnutrition.

The continued production of quality seed through retention of protein quality complemented by effective delivery mechanisms to farmers are important steps to scale up use of the hybrids. An active role by NARC and other value chain actors in Pakistan can help make seeds more easily accessible and available.

Scientists in Afghanistan set new program to raise wheat harvests

KABUL (CIMMYT) – Inadequate access to new disease-resistant varieties and short supplies of certified seed are holding back wheat output and contributing to rising food insecurity in Afghanistan, according to more than 50 national and international wheat experts.

Wheat scientists and policymakers discussed challenges to the country’s most-produced crop during a two-day meeting at Agricultural Research Institute of Afghanistan (ARIA) headquarters in Kabul, as part of the 5th Annual Wheat Researchers’ Workshop in November 2016. They took stock of constraints to the 2017 winter wheat crop, including dry autumn weather and rapidly-evolving strains of the deadly wheat disease known as yellow rust.

“Old wheat varieties are falling prey to new races of rust,” said Qudrat Soofizada, director for Adaptive Research at ARIA, pointing out that the country’s 2016 wheat harvest had remained below 5 million tons for the second year in a row, after a record harvest of more than 5.3 million tons in 2014.

The workshop was attended by 51 participants belonging to several ARIA research stations and experts from the International Maize and Wheat Improvement Center (CIMMYT), the Australian Center for International Agricultural Research (ACIAR) and World Bank’s Afghanistan Agriculture Input Project (AAIP).

Afghanistan has been importing around 2.5 million tons of cereal grain — mainly wheat — in the last two years, with most of that coming from Kazakhstan and Pakistan, according to recent reports from the Food and Agriculture Organization (FAO) of the United Nations.

“Most wheat farmers save grain from prior harvests and use that as seed, rather than sowing certified seed of newer, high-yielding and disease resistant varieties,” said Rajiv Sharma, CIMMYT senior scientist and representative at the center’s office in Afghanistan. “This is holding back the country’s wheat productivity potential.”

Sharma explained that CIMMYT has been supporting efforts of Afghanistan’s Ministry of Agriculture, Irrigation and Livestock (MAIL) to boost supplies of certified seed of improved varieties and of critical inputs like fertilizer.

“CIMMYT has worked with Afghanistan wheat scientists for decades and more than 90 percent of the country’s certified wheat varieties contain genetic contributions from our global breeding efforts,” Sharma explained.

Since 2012, the center has organised more than 1,700 wheat variety demonstrations on farmers’ fields and trained over 1,000 farmers. CIMMYT scientists are also conducting field and DNA analyses of Afghan wheats, which will allow faster and more effective breeding.

The FAO reports showed that the government, FAO and diverse non-governmental organizations had distributed some 10,000 tons of certified seed of improved wheat varieties for the current planting season. With that amount of seed farmers can sow around 67,000 hectares, but this is only some 3 percent of the country’s approximately 2.5 million-hectare wheat area.

“We have been informing the National Seed Board about older varieties that are susceptible to the rusts,” said Ghiasudin Ghanizada, head of wheat pathology at MAIL/ARIA, Kabul, adding that efforts were being made to take such varieties out of the seed supply chain.

After discussions, Ghanizada and MAIL/ARIA associates M. Hashim Azmatyar and Abdul Latif Rasekh presented the technical program for breeding, pathology and agronomy activities to end 2016 and start off 2017.

Zubair Omid, hub coordinator, CIMMYT-Afghanistan, presented results of wheat farmer field demonstrations, informing that grain yields in the demonstrations ranged from 2.8 to 7.6 tons per hectare.

T.S. Pakbin, former director of ARIA, inaugurated the meeting and highlighted CIMMYT contributions to Afghanistan’s wheat improvement work. M.Q. Obaidi, director of ARIA, thanked participants for traveling long distances to attend, despite security concerns. Nabi Hashimi, research officer, CIMMYT-Afghanistan, welcomed participants on behalf of CIMMYT and wished them good luck for the 2016-17 season.

Wheat breeding trial results were presented by Zamarai Ahmadzada from Darulaman Research Station, Kabul; Aziz Osmani from Urad Khan Research Station, Herat; Shakib Attaye from Shisham Bagh Research Station, Nangarhar; Abdul Manan from Bolan Research Station, Helmand; Said Bahram from Central Farm, Kunduz; Najibullah Jahid from Kohkaran Research Station, Kandahar; and Sarwar Aryan from Mulla Ghulam Research Station, Bamyan.

Agronomy results from the research stations of Badakhshan, Herat, Kabul, Kunduz, Helmand and Bamyan were also presented and summarized by Abdul Latif Rasikh, head of Wheat Agronomy, ARIA headquarters, Badam Bagh, Kabul

ISLAMABAD (CIMMYT) — Public and private sector maize stakeholders came together to discuss the International Maize and Wheat Improvement Center’s (CIMMYT) maize interventions and innovations in Pakistan during a recent radio talk show hosted by the Pakistan Broadcasting Corporation.

The radio talk show was organized by the United States Agency for International Development (USAID) and focused on maize development under the CIMMYT-led Agricultural Innovation Program (AIP), supported by USAID in collaboration with national partners. The Pakistan Broadcasting Corporation conducted the show in Urdu and English and aired it throughout the country.

One of the show panelists, Zahid Shafique, program leader from Pakistan’s National Agricultural Research Center, gave an overview of AIP’s interventions and expressed the hope that the program will help Pakistan develop affordable hybrid maize seed, which is currently sold for $6-8 per kilogram, one of the highest prices in South Asia.

Faisal Hayat, deputy manager of the seed company Jullundur Private Limited, noted that CIMMYT’s joint evaluation of hybrids and open-pollinated varieties (OPVs) with AIP maize partners has helped the private sector develop improved hybrids and OPVs that are better adapted to Pakistan’s diverse climates. Capacity building efforts to ensure quality seed production is key to ensuring the sustainability of AIP after its completion said Nazim Ali, an agricultural economist with USAID.

CIMMYT was represented by maize improvement and seed systems specialist AbduRahman Beshir, who briefed the panelists about the introduction and nationwide testing of diverse germplasm and the allocation of well adapted maize hybrids and OPVs to partners.

DINAJPUR, Bangladesh (CIMMYT) — Responding to a 2016 outbreak of the deadly and little-understood crop disease “wheat blast” in Bangladesh, 40 wheat pathologists, breeders and agronomists from Bangladesh, India and Nepal have gathered to hone their skills through surveillance exercises in farmers’ fields and molecular analysis of the causal fungus in laboratories of the Bangladesh Agricultural Research Institute (BARI) at Gazipur.

Entitled “Taking action to mitigate the threat of wheat blast in South Asia: Disease surveillance and monitoring skills training,” the 13-day program was launched on 4 February at BARI’s Wheat Research Center (WRC), Bangladesh Agriculture Research Institute (BARI), Dinajpur, in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), the CGIAR research program on wheat, the Delivering Genetic Gain in Wheat (DGGW) project led by Cornell University, and Kansas State University (KSU).

The 2016 Bangladesh outbreak was the first time wheat blast has appeared in South Asia. The disease struck 15,000 hectares in 7 southwestern and southern districts of Bangladesh, with crop losses averaging 25-30 percent and reaching 100 percent in some cases.

In response the Bangladesh Ministry of Agriculture formed a task force through the Bangladesh Agricultural Research Council (BARC) to help develop and distribute resistant cultivars and pursue integrated agronomic control measures. A factsheet distributed to wheat farmers is raising awareness about the disease and particularly its identification and management.

Caused by the fungus Magnaporthe oryzae pathotype Triticum (MoT) and first discovered in Paraná State, Brazil, in the mid-1980s, wheat blast constitutes a major constraint to wheat production in South America. The sudden appearance of a highly virulent MoT strain in Bangladesh presents a serious threat for food and income security in South Asia, home to 300 million undernourished people and whose inhabitants consume over 100 million tons of wheat each year.

Experts from CIMMYT, Cornell University and Kansas State University, along with scientists from BARI and Bangladesh Agricultural University (BAU), are serving as instructors and facilitators.

“This training will increase the capacity of Bangladesh and neighboring country scientists, thereby strengthening research on wheat blast and monitoring disease through intensive surveillance,” said the Additional Secretary (Research), Ministry of Agriculture Md. Fazle Wahid Khondaker, chief guest in the inaugural session. Arun K. Joshi, CIMMYT-India country representative, T.P. Tiwari, CIMMYT-Bangladesh country representative, Prof. Dr. Bahadur Meah from BAU, Mymensingh, and Additional Director, Department of Agricultural Extension, and Md. Julfikar Haider were present as special guests. Dr. N.C.D. Barma, WRC, BARI chaired the session, and BARI Director General Dr. Abul Kalam Azad took part.

The training program is funded by BARI, CIMMYT, DGGW, the United States Agency for International Development (USAID) and the Bill & Melinda Gates Foundation through the CIMMYT-led Cereal Systems Initiative for South Asia (CSISA) and CSISA- Mechanization projects, as well as the Australian Center for International Agricultural Research (ACIAR). The DGGW project is funded by the Bill & Melinda Gates Foundation and the United Kingdom’s Department for International Development (DFID) through UK Aid.

JESSORE, Bangladesh (CIMMYT) — USAID’s Deputy Administrator Gary Lindon visited Bangladesh in November 2016 to learn how the International Maize and Wheat Improvement Center (CIMMYT) engages with partners to help smallholder farmers uptake sustainable agriculture practices, as well as to observe the private sector’s role in producing farm machinery that is faster, more environmentally friendly and affordable for smallholder farmers.

One example of sustainable, smallholder-friendly machinery being promoted by CIMMYT with national partners is the two-wheeled mechanical reaper, a tool that’s proven to save farmers time and money, and helps them cope with increasing labor scarcity in Bangladesh — a trend that has continued to rise as Bangladesh develops economically and more people leave rural areas for off-farm employment, according to Timothy Krupnik, systems agronomist at CIMMYT.

“Mechanical harvesting also allows farmers to more quickly clear the field and sow the next crop, which has yield advantages for planting crops like wheat,” said Krupnik.

Lindon also met with service providers — entrepreneurial farmers turned businessmen — who have purchased the two-wheeled mechanical reapers and are now offering their harvesting services to smallholder farmers at an affordable fee.

“The local service provision business model is key to unlocking agricultural and entrepreneurial capacity in rural Bangladesh,” said Kevin Robbins, director of programs at International Development Enterprises, one of CIMMYT’s partners in Bangladesh. “We’ve seen just over 1,000 local service providers provide agricultural machinery services to over 40,000 farmers — catalyzing a level of impact that would not have been possible if we had promoted a traditional model where every farmer buys his or her own machine.”

Shafiqul Islam, CIMMYT’s Jessore hub coordinator, also explained that through mechanical harvesting, farmers save $48 per hectare, while service providers earn approximately $31 per hectare.

“In Bangladesh, private sector companies are working hard to promote agricultural machinery that develops the sector,” said Mohammad Jamil, managing director at Metal Pvt. Ltd., a leading private company in Bangladesh that sells reapers. “We want to do more business — the kind of business that changes the lives of farmers through increasing the sales of appropriate agricultural machinery. There’s a strong incentive for us to endorse the adoption of new technologies, which in turn increases food production, boosts farmer income and supports our economy. It’s a win-win business model and a sustainable way to develop our country.”

The team later visited lentil and maize fields that had been seeded directly with seeders, affordable machines that can attach directly to two-wheeled tractors, which are increasingly being used by farmers in Bangladesh. Farmers attending the USAID field visit commented that through the use of two-wheel tractor attachable seeders they can save $60 per hectare by avoiding recurring tillage and manual seeding costs.

“This machine also helps farmers to sow seeds on time, as recommended by agronomists, because direct sowing saves farmers’ 7-10 days compared to full tillage and manual sowing systems,” explained Islam.

CIMMYT launched the Cereal Systems Initiative for South Asia (CSISA) program in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems. Through this program, CIMMYT is operating rural “innovation hubs” in Bangladesh, India and Nepal to increase the adoption of various resource-conserving and climate-resilient technologies, and to improve farmer access to market information and enterprise development.

CIMMYT scientist cautions against new threats from wheat rust diseases

EL BATAN, Mexico (CIMMYT) – Scientists are concerned over the proliferation of highly virulent fungal wheat diseases, including two new races of yellow rust – one in Europe and North Africa, the other taking hold in East Africa and Central Asia – and a new race of stem rust emerging in Europe.

The collaborative Global Rust Reference Center (GRRC) hosted by Aarhus University in Denmark and including the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA), was instrumental in identifying the new races of yellow and stem rust.

A strategic tool developed by David Hodson, a senior scientist with CIMMYT plays a key role in monitoring the movement of wheat-rust pathogens, helping farmers combat the disease in time to save crops and prevent food insecurity.

“We see an alarming increase in severe disease, more disease diversity and rapid spread,” said Hodson, who invented the Rust Tracker field surveillance tool.

Last year, the Italian island of Sicily was badly hit by a strain of wheat stem rust – an event not seen in Europe since the 1950s, following concerted efforts by wheat breeders to eliminate it.

Stem rust appears as a reddish-brown fungal build-up on wheat stems or leaves, stunting and weakening plants, preventing kernels from forming, leading to shriveled grain and potential crop losses of 50 to 100 percent.

Dispersal modeling, undertaken by the University of Cambridge and the UK Met Office, which forecasts weather and climate change, indicates that spores from the Sicilian outbreak could potentially have spread within the Mediterranean wheat growing region, but scientists are unsure whether they will successfully over-winter, surviving and proliferating, according to a recent story in the journal Nature.

EARLY WARNING

“Several factors may be influencing the changes and rapid spread: increased travel and trade; increasing pathogen populations; more uniform cropping systems and also climate change, but the rapid changes we are observing highlight the need for an enhanced early-warning system,” said Hodson, a member of an international team of scientists collaborating under the Delivering Genetic Gain in Wheat (DGGW) project administered by Cornell University through the Borlaug Global Rust Initiative (BGRI).

Scientists engaged with the major four-year international project – which has a budget of $34.5 million due to grants equalling $24 million from the Bill & Melinda Gates Foundation and a recent $10.5 million grant from UK Aid (Britain’s Department for International Development, or DFID) – use comparative genomics and big data to develop new wheat varieties. The aim is to help governments provide smallholder farmers in the developing world with seeds incorporating resilience to environmental stresses and diseases through local entrepreneurial distributors.

“The sooner farmers are notified of a potential rust outbreak, the better chance they have to save their crops through fungicides or by planting resilient wheat varieties,” Hodson said.

“It’s a constant challenge. We’re always on the lookout for new diseases and variants on old diseases to put the wheels in motion to aid governments who can distribute seeds bred specifically to outsmart rusts.”

However, the long-term sustainability of these vital disease-monitoring systems is uncertain. Despite the significant investments, challenges remain, Hodson said.

“It’s worrying that just as stem rust is re-appearing in Europe we’re at risk of losing the only stem rust pathotyping capacity in Europe at GRRC, due to a funding shortfall. Given the threats and changes we are observing, there really is a critical need for a long-term strategy to address major crop diseases.”

TRACKER ORIGINS

The online Rust Tracker was originally conceived as a tool to battle stem rust, including the lethal Ug99 race, which since its discovery in 1998 has spread from Uganda into the Middle East and is now found in 13 countries. If Ug99 takes hold in a field it can completely wipe out a farmer’s crop. In developing countries, farmers have more difficulty accessing and affording fungicides, which can potentially save a crop.

Under the Durable Rust Resistance in Wheat project, the predecessor to the DGGW project, BGRI-affiliated scientists aimed to prevent the spread of Ug99 into the major global breadbaskets of China and India. So far, they have succeeded in keeping it in check and raising awareness among governments and farmers of its potentially devastating impact.

“Researchers and farmers are connected in the global village,” Hodson said. “Plant pathogens know no borders. We must leave no stone unturned in our efforts to understand the dynamics of wheat rusts, how they’re changing, where they’re spreading and why. If wheat scientists can help prevent a food crisis, we’re doing our job to help maintain political and economic stability in the world.”

Breaking Ground: Caixia Lan on identifying building blocks for rust resistant wheat

EL BATAN, Mexico (CIMMYT) – Support for research into breeding crops resistant to wheat rust is essential to manage the spread of the deadly disease, which has caused billions of dollars of yield losses globally in recent years, said Caixia Lan, a wheat rust expert at the International Maize and Wheat Improvement Center (CIMMYT).

Rust disease has historically been a menace to wheat production worldwide. Although agricultural scientists manage the disease by breeding wheat varieties with rust resistant traits, the emergence of new races hinders progress and demands continued research, said the scientist.

With outbreaks of new strands reported in Europe, Africa and Central Asia, wheat rust presents an intensifying threat to the over 1 billion people in the developing world who rely on the crop as a source of food and for their livelihoods.

One of the most recent rust races, Ug99, was detected in 1998 and has since spread across 13 countries, alone causing crop losses of $3 billion in Africa, the Middle East and South Asia, said Lan.

Working with CIMMYT’s Global Wheat Program Lan is identifying and mapping adult-plant resistance genes to different races of rust (leaf, stripe, and stem) in bread and durum wheat and transferring them into new varieties that help secure farmer’s production.

Growing up in an area dependent on agriculture in rural China, Lan knows all too well the impact crop disease and natural disaster has on family food security and livelihoods. The struggles of smallholder farmers to feed and support their families motivated her to pursue a career in agriculture for development, but it was not until university that she became inspired by the improvements made to crop yield through genetic manipulation and breeding, she said.

After completing her doctoral degree at the Chinese Academy of Agricultural Sciences, and working as a wheat molecular breeding lecturer at Huazhong Agricultural University, Lan was named the Borlaug Global Rust Initiative Women in Technology Early Career Winner in 2011. Lan joined CIMMYT in a post-doctoral position and currently works as a scientist to improve wheat’s resistance to rust.

Rust is a fungal disease that uses wheat plants as a host, sucking vital nutrients and sugars from the plant leaving it to wither and die. Without intervention, wheat rust spreads due to the release of billions of spores, which travel by wind to other plants, crops, regions or countries. Spores have the potential to start new infection, ravage crops and threaten global food security.

The science behind building genetic resistance takes two forms known as major (or race-specific) genes and adult-plant resistance based on minor genes. Major resistance genes protect the wheat plants from infection by specific strains of rust. While adult plant resistance, Lan’s area of specialization, stunts the pathogen by reducing the infection frequency and limiting its nutrient intake from the host wheat plant. Some of the longer-lasting adult-plant resistance genes have been shown to provide protection against multiple diseases for decades and have not succumbed to a mutated strain of rust so far.

Replacing wheat crops for varieties bred with several rust-resistant genes acts as a safeguard for occasions when the pathogen mutates to overcome one resistant gene as the others continue the defense, Lan said.

Lan has identified a number of rust resistant genes in CIMMYT germplasm and developed molecular markers, which are fragments of DNA associated with a specific location in the genome. However, as new races of the disease emerge and old ones continue to spread, research identifying durable and multiple rust resistant genes and breeding them into crops is of high importance, she said.

Crop sensors sharpen nitrogen management for wheat in Pakistan

ISLAMABAD (CIMMYT) – Pakistani and the International Maize and Wheat Improvement Center (CIMMYT) scientists are working with wheat farmers to test and promote precision agriculture technology that allows the farmers to save money, maintain high yields and reduce the environmentally harmful overuse of nitrogen fertilizer.

Wheat is planted on more than 9 million hectares in Pakistan each year. Of this, 85 percent is grown under irrigation in farming systems that include several crops.

Farmers may apply nearly 190 kilograms of nitrogen fertilizer per hectare of wheat, placing a third of this when they sow and the remainder in one-to-several partial applications during the crop cycle. Often, the plants fail to take up and use all of the fertilizer applied. More precise management of crop nutrients could increase farmers’ profits by saving fertilizer with no loss of yield, as well as reducing the presence of excess nitrogen that turns into greenhouse gases.

Precision nutrient management means applying the right source of plant nutrients at the right rate, at the right time and in the right place. CIMMYT is working across the globe to create new technologies that are locally adapted to help farmers apply the most precise dosage of fertilizer possible at the right time, so it is taken up and used most effectively by the crop.

CIMMYT and the Borlaug Institute for South Asia (BISA) have developed the application “urea calculator” for cell phones. In this process, a Green Seeker handheld crop sensor quickly assesses crop vigor and provides readings that are used by the urea calculator to furnish an optimal recommendation on the amount of nitrogen fertilizer the wheat crop needs.

Tests with the crop sensor/calculator combination on more than 35 farmer fields during 2016 in Pakistan results showed that 35 kilograms of nitrogen per hectare could be saved without any loss in grain yield. This technology is being evaluated and demonstrated in Pakistan as part of the CIMMYT-led Agricultural Innovation Program (AIP), supported by the United States Agency for International Development in collaboration with Pakistan partners.

CIMMYT recently began work in four provinces of Pakistan, providing Green Seekers and training to AIP research, extension and private partners. Fifty-five specialists in all took part in training events held at the Wheat Research Institute Sakrand, Sind Province; the Rice Research Institute KSK, Punjab Province; and the Model Farm Service Center, Nowshera, Khyber Pakhtunkhwa Province.

Training and new partnerships will help national partners to demonstrate and disseminate sustainable farming practices to wheat farmers throughout Pakistan.
