Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

‘The 50 PACT’ Conference: collaborate for better food security in South Asia

Written by on September 3, 2013. Posted in Features.

The-50-PACT Farmers need to be more involved in developing and refining technology. This was one of the key conclusions of a technology working group comprised of leading Asian scientists, representatives of farmer groups and entrepreneurs who met during “The 50 Pact,” an international conference jointly organized by the Borlaug Institute for South Asia (BISA) and the Indian Council of Agricultural Research (ICAR) to celebrate 50 years of Dr. Norman Borlaug’s first visit to India. Held in New Delhi during 16-17 August, the event brought together more than 200 participants from agriculture institutions, the government, think tanks, industry, and civil society of various countries including Afghanistan, Bangladesh, Belgium, Germany, India, Malaysia, Mexico, Nepal, Sri Lanka, and the United States.

South Asia is the most populous region in the world and several models predict that this region is going to be dramatically impacted by climate change. “We must devise new ways to feed more people with less land, less water and under more difficult climate change conditions,” said Thomas Lumpkin, Director General of CIMMYT, highlighting a significant challenge that requires critical innovations, collaborations and commitments to solve food insecurity and strengthen agriculture in South Asia. This sentiment was echoed by others in the opening session of the conference, including S. Ayyappan, director general of ICAR, government of India, R.S. Paroda, president of Trust for Advancement of Agricultural Sciences (TAAS), R.B. Singh, president of the National Academy of Agricultural Sciences (NAAS), Swapan Datta, ICAR and Marianne Bänzinger of CIMMYT. Remembering their personal interactions with Dr. Borlaug, “the Nobel laureate with a heart for the poor,” and his association with CIMMYT and India, they also felt the need to make a pact to bring about a second green revolution in the South Asia region. M.S. Swaminathan, a legendary figure in Indian agriculture, paid tribute to Dr. Borlaug for his immense contribution in agriculture during the opening ceremony. “From Bengal famine to Right to Food Act of India, it has been a historic transition and Dr. Borlaug played a very important role in this transition through his work in the last 50 years,” Swaminathan said. Jeanie Laube Borlaug, chairperson of BGRI and the daughter of Dr. Norman Borlaug, presented Swaminathan with the Dr. Norman Borlaug Award.

Technology and innovations will play a key role
Bangladesh, India, Nepal, and Sri Lanka will have to work together to find regional solutions to food insecurity. Representatives from these countries talked about different agricultural developments during the post-green revolution period and emerging challenges and opportunities. They also highlighted how the BISA, with its mandate, furthers research on farming systems in addition to focusing on an eco-regional approach involving other CG centers. Utilizing all technologies, including molecular breeding, biotechnology, precision agronomy, and mobile-based decision making will be crucial. The session on technology highlighted this and also pushed for greater involvement of farmers at every step of new technology development. It is important to capture the process of adoption of innovation by farmers and use new technology to provide feedback to the researchers. The group advocated for increased political will and a better policy environment on the adoption of GM crops. Making agriculture profitable is important for producers and the entire agricultural value chain. Ramesh Chand of ICAR said that his recent analysis in India shows the real farm income is not declining, but the income gap between agricultural and non-agricultural income is widening. Agricultural infrastructure is not well developed, investments are low and land fragmentation is increasing. These are major concerns for this sector. The participants talked about a need for an enhanced cyber infrastructure for crop research, open access to agriculture database, and strengthening the value chain balancing the role of market, price, and technologies.

Greater regional synergy needed
More emphasis on synergy, partnerships, farmer’s welfare, productivity, profitability, and nutrition will be critical to address the problem of hidden hunger and food security in this region. Other areas to focus on include providing access to and the use of cutting edge research and new technologies that are not yet available in the region, ensuring commitments from governments and other donors for investments in agricultural research, advocating for a policy environment that embraces new technologies and invests in agricultural research, building a regional platform of collaboration with partners from all sectors, research centers, governments, the scientific world, and the farming community who share our mandate to transform farmers’ lives in the region.

Farming systems design: to feed a changing world

Written by on September 2, 2013. Posted in News.

Farming-systems2 Farming systems all over the world face complex problems in terms of production, such as natural resource depletion, climate change, increasing food demand, and volatile prices. Farmers have to adapt to continuously changing conditions to produce food. ‘Farming systems design’ is an approach that aims at modifying designs of farming systems to sustainably increase the overall productivity and profitability of the systems—and, hopefully, the welfare of individual farming families—while considering interactions in the system. Interactions are important features of farm system structure and operation. They may occur between the various components, including crop-crop, crop-livestock, and farm-household as well as on-farm-off-farm activities as they compete for the same resources.

More than 70 papers on systems research were recently presented at the 4th International Farming Systems Design Symposium in Lanzhou, China. CIMMYT researchers were represented by Bruno Gérard, director of the Conservation Agriculture Program, and CIMMYT agronomists Santiago López Ridaura, Tek Sakpota, Isaiah Nyagumbo, and Jack McHugh. The conference took place from 19- 22 August and was organized by WHEAT CRP Chinese partner Gansu Academy of Agricultural Sciences and others. Research with a farming systems perspective can have various objectives ranging from increasing the amount of knowledge about farming systems to solving specific problems in the farming system. If it is commonly agreed that cross-links between disciplines and participatory approaches are needed to provide solutions, “there is no silver bullet approach to be expected,” said keynote speaker David Norman, professor emeritus of agricultural economics at Kansas State University and pioneer in the field of Farming Systems Research (FSR). “The most important is to take into account the whole farming system and bring together all stakeholders,” Norman explained. “If a project works on one crop, like CIMMYT on maize for instance, FSR would look at how maize impacted if they have livestock, the influence on livestock components, etc. The reductionist approach would look at how improving productivity of one item without considering the whole farming system.”

Farming-systems3 For Peter Carberry, chair of the Program Committee and deputy director at the Commonwealth Scientific and Industrial Research Organization (CSIRO), “this conference is about bringing those who are interested in a more integrative science together, and have all the different disciplines articulating possibilities for the future in terms of agriculture and farming.” One of the benefits of the conference for him is that among the 300 participants, there were 200 Chinese researchers and students, some who may not have been exposed to this thinking before. “We have a mix of people who are familiar with Farming Systems Design and others who are just starting learning about it; it is a great opportunity,” Carberry said. LingLing Li, professor at Gansu Agricultural University and keynote speaker, shared a similar point of view. “This platform is a really good start for all experts and students involved in Farming Systems Design, as we do not yet have many scientists doing this type of research in China,” Li said.

On day one and two, there were several presentations on Africa and on the Sustainable Intensification of Maize-Legume Systems for Food Security in Eastern and Southern Africa (SIMLESA) program led and mentored by CIMMYT. “SIMLESA has been innovating in so many different ways, firstly about systems and farming systems, participatory approaches and new experiments in research methodology by targeting not only productivity but also reduced risks, which we have heard a lot in this conference. Because for farmers risks are sometimes more important than total yields,” said John Dixon, senior advisor in the Australian Center for International Agricultural Research (ACIAR) and principal regional coordinator for Africa. Important questions raised throughout the conference included how to get better participation with farmers, how to get the private sector involved for marketing through innovation platforms, how to manage risks and how scientists can work much better at systems productivity to understand better nutrition, as one of the outcomes, “to better feed our future farmers,” Dixon insisted. On the last day, a special session brought together Australian and Chinese farmers to discuss farming operations. This opportunity to exchange information and share experiences related to climate risks, prices or yields created enthusiasm on both parts.

Announcing Borlaug100

Written by on August 28, 2013. Posted in News.

On 25 March 1914, a man who would change the face of agriculture around the world was born. Dr. Norman Borlaug, tireless hunger fighter and one of only six people to have won the Presidential Medal of Freedom, the Congressional Gold Medal, and the Nobel Peace Prize, would celebrate his 100th birthday next year.

To celebrate his life and legacy and inspire a new generation to carry on his work, CIMMYT is holding Borlaug Summit on Wheat for Food Security at the Universidad de La Salle, Ciudad Obregón, Sonora, Mexico, from 25-28 March 2014. Dr. Borlaug’s 100th birthday presents an opportunity to not only celebrate his legacy, but also discuss the present and launch a new agricultural renaissance.

Dr. Borlaug began working in Mexico in the 1940s. He lead CIMMYT’s Wheat Program from 1963 to 1979 and remained a resident part-time consultant until his death. He spent most of his working life in Mexico researching and developing new types of high-yielding, disease-resistant wheat varieties. It is here that he became known as the “Father of the Green Revolution.”

The summit will bring together thought leaders, policymakers, and representatives of leading agricultural research-for-development organizations, both public and private. This premier gathering brings together science, policy, and business from developed and emerging markets to illustrate wheat’s potential. Borlaug100 participants will visit the Campo Experimental de Norman E. Borlaug (CENEB) and celebrate Dr. Borlaug’s 100th birthday with a traditional carne asada—as Dr. Borlaug loved—on 25 March. The birthday celebrations will be followed by a conference at the Universidad de La Salle (26-28 March) during which participants will hear inspiring and insightful talks about the history and future of wheat as a crop.

Howard Buffett is the keynote speaker for the event. Other confirmed speakers include Louise Fresco, Catherine Bertini, Per Pinstrup-Andersen, Robert Paarlberg, Rachel Laudan, Steve Jennings, Peter Raven, David Nyameino, and Ronnie Coffman. These events will be preceded by the Borlaug Global Rust Initiative Technical Workshop during 23-24 March. Registration for the event will open in September.

For more information and updates, visit the newly launched Borlaug100 website and follow hashtag #Borlaug100 on Twitter and other social media. We would like to thank Jenny Nelson and Petr Kosina, the main organizers of the event, for their hard work! borlaug100_logo-new

CIMMYT welcomes new partner in MasAgro

Written by on August 26, 2013. Posted in News.

CIMMYT and leading agribusiness Syngenta México signed an agreement this month to work together in efforts aimed at sustainably increasing crop production in Mexico while protecting the environment and contributing to food security.

Syngenta will collaborate with CIMMYT to do research on conservation agriculture in four experimental platforms. The new project follows the same logic and goals of MasAgro, the Sustainable Modernization of Traditional Agriculture, which CIMMYT implements in coordination with Mexico’s Ministry of Agriculture, Livestock, Rural Development, Fisheries, and Food (SAGARPA). MasAgro aims to build the capacities of small-scale farmers to encourage the adoption of sustainable farming practices and technologies that may help increase maize and wheat output, in line with Mexico’s recently announced “Crusade Against Hunger.”

The three-year agreement will focus on improving maize productivity, generating more income for farmers, protecting natural resources, and combining Syngenta’s expertise with local knowledge to work directly with farmers. Syngenta and CIMMYT will also develop joint research protocols and offer courses in crop protection and adequate use of agrochemicals.

Soil conservation and protecting the biodiversity of undergrowth, small animals and beneficial insects will be another focus of the agreement. Both organizations have also expressed their interest in improving communication and information technologies (ITCs) in the agricultural sector.

Representatives from Syngenta and SAGARPA visited CIMMYT’s El Batán campus to see its conservation agriculture trial plots and germplasm bank before signing the agreement on 14 August 2013. Javier Valdés, Director General of Syngenta México, said during the ceremony that the agreement shows the company’s commitment to food security and sustainability. “We will continue to promote the formation of important publicprivate partnerships like the one we’re celebrating today to increase the productivity of crops like maize and wheat, which will help with economic, social and environmental development in rural communities in the country,” he said.

CIMMYT has worked on projects with Syngenta in the past. This new collaboration has been developing for years and is an example of cooperation between an international research organization and a private business. Scientific collaboration is essential for making maize production in Mexico sustainable and profitable for resource-constrained farmers, said Bram Govaerts, Deputy Director of CIMMYT’s Global Conservation Agriculture Program.

Govaerts said he thought the new partnership would have the same success as other CIMMYT programs worldwide. Belisario Domínguez, the director general of productivity and technological development for SAGARPA, said the vision of MasAgro is essential to the government’s national fight against hunger. Domínguez congratulated the two groups for forming the alliance and said that similar projects will promote the growth of the agricultural sector.

The struggle of maize against climate change in Zimbabwe

Written by on August 21, 2013. Posted in News.

usar-esta-foto-Foto-2 “Maize production is likely to suffer the most due to climate change compared to other crops in Southern Africa,” said CIMMYT physiologist Jill Cairns, who presented on CIMMYT work under the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) at the FAO Agriculture Coordination & Information Forum in Harare, Zimbabwe, on 25 July 2013. During her presentation on future climate scenarios in Zimbabwe, Cairns focused on adaptation strategies to climate change, temperature and rainfall projections for 2050, and climate change implications for maize production.

CIMMYT’s ongoing research in Zimbabwe shows an increase in extreme temperature events and the intensity of droughts, which are conditions likely to reduce harvests and affect the suitability of current crops. Discussing the key adaptation strategies for Zimbabwe, including improved varieties, redefined agro-ecological zones, new policies, and better management, Cairns stressed that the initial climate change projections are not downscaled enough to make decisions at the country level. This is important as agricultural responses to climate change cannot be determined and priorities for adaptation strategies cannot be set without the ability to accurately predict future climate scenarios.

The major climate-related threats to maize in Zimbabwe right now are low rainfall and drought stress under high temperatures. “CIMMYT research in Southern Africa has shown that maize production linearly decreases with every accumulated degree above 30 degrees,” said Cairns. “While the amount of rainfall during the maize growing season in the drought-prone areas may increase slightly, it is unlikely to translate into higher yields as evapotranspiration will increase under higher temperatures.”

The challenges are not easy to tackle, but there are opportunities to offset losses. To mitigate the effect of increased temperature, maize lines with tolerance to combined drought and heat stress need to be developed. Such lines have been already identified and can be used to adapt maize production to climate change in Southern Africa.

The presentation, prepared by Cairns with significant input from CIMMYT specialist in geographic information systems, Kai Sonder, was well received by the FAO representatives.

Strengthening CIMMYT cooperation with Russia

CIMMYT Global Wheat Program director Hans-Joachim Braun and winter wheat breeder Alex Morgounov attended the G-20 Meeting of Agricultural Chief Scientists in Moscow, Russia, on 24-25 July 2013 where they presented on CRP WHEAT and the cooperation between CIMMYT and Russia. The G-20 meeting adopted a declaration stating the importance of cooperation in agricultural research and defining future priority areas and directions for this cooperation. The meeting also emphasized the involvement of the Russian Federation in international agricultural research and development. In 2013, Russia supported CRP WHEAT with US$1.1 million, part of which was allocated to the Kazakhstan-Siberian Network on Wheat Improvement (KASIB) for spring wheat improvement and part to Strategic Initiatives related to biotic and abiotic stresses. The funds utilization and strengthening of cooperation with Russian scientists were discussed with Sergey Kiselev, director of Eurasian Center of Food Security at Lomonosov Moscow State University, and Ivan Savchenko, vice president of the Russian Academy of Agricultural Sciences.

Following the meeting, Braun and Morgounov visited Omsk in Western Siberia on 26 July to sign a sub-grant agreement between CIMMYT and Omsk State Agrarian University on technical coordination of KASIB activities; development of shuttle breeding germplasm for Russian cooperating institutions; and expansion of training and visits between the university and CIMMYT, and attendance of regional and international conferences for Russian scientists.

The subsequent field visits to the university and Siberian Agricultural Research Institute demonstrated the value of regional germplasm exchange and improved adaptation of the shuttle germplasm developed for the region in Mexico and Turkey. “The shuttle breeding program, initiated in early 2000s to incorporate rusts resistance into local material, finally bears fruit as several advanced lines competitive with local checks have been identified and will be considered as variety candidates in the near future,” said Morgounov. As Northern Kazakhstan and Western Siberia jointly cultivate almost 20 million hectares of high latitude spring-planted wheat, this area plays a significant role in global wheat supply.

Impressive adoption of metal silos in western Kenya

Written by on August 13, 2013. Posted in Features.

metal-silos1 “When Richard Pamo, the then Caritas Development Coordinator [Homa Bay] introduced the metal silo technology to me in 2008, I felt I had received the solution to my perennial problems of storing my grains, particularly maize that was prone to weevil attack,” said Bishop Philip Anyolo of the Catholic Diocese of Homa Bay, Kenya, to a visiting team from the Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP-II). “I instantly ordered two silos, of 1- and 1.8-ton capacity. And I have never been disappointed. I was so satisfied with the ability of the metal silos to protect my maize against weevils that I acquired another 720-kg capacity metal silo for my mother in 2009.”

The Bishop, who was among the first people to use metal silos after the project introduction in Kenya, noted how widely appreciated the technology has become: “Since I acquired the metal silos, word about its effectiveness has spread within and beyond my home county of Bungoma, which was not even in the project target area. Like in Homa Bay, farmers there are making all efforts to acquire the metal silos.” And it is not just the farmers who use the technology these days; Rose Owanda in the poultry business has acquired six 2.7-ton capacity metal silos. “I intend to be buying grains from the market during times of glut. This will not only ensure that I buy the grains at the lowest prices, I am assured of enough grain for making the feeds for the birds throughout the year.” The success of the silo has also created brisk business for trained metal silo artisans who are receiving orders from beyond the Homa Bay County.

metal-silos2 Impressed with the technology, the Bishop has advised all schools and institutions sponsored by the Catholic Church in Homa Bay to acquire metal silos for grain storage. His advice has since caught the attention of other institutions, including St. Vincent De Paul Boys Boarding School in Kisii County who acquired seven 2.7-ton metal silos in December 2011 after the Nyambururu Teachers College, Kisii County, bought ten 1.8-ton silos earlier in the year; the College had learned of the technology from the Kokwaro Secondary School in Homa Bay Diocese who had acquired eight 2.7-ton silos in 2010. Since the launch of EGSP-II in October 2012 in Kenya, Homa Bay farmers have acquired 230 metal silos, and institutions in the area, particularly boarding schools and colleges, have bought 47 more, according to Beautrice Otieno, Livelihoods Program Manager at Caritas Homa Bay and the site coordinator for western Kenya.

metal-silos3 “Production is all in vain if farmers cannot store the harvested produce. Effective storage is even more critical at these times of climate change, where the associated weather vagaries adversely affect production. Whatever little that we produce should be well managed, and that includes being well stored for use at the desired time,” stressed Jennifer Ndege, Chief Officer, Agriculture, Livestock and Fisheries at Homa Bay County. Tadele Tefera, CIMMYT entomologist and EGSP-II coordinator, agrees: “A lot of agencies focus on increasing productivity but very few on the management of what has been harvested. Yet this is a very important aspect in any food security chain.” The information was collected during an assessment tour of Homa Bay and surrounding counties conducted by the EGSP-II Kenyan team during 15-19 July 2013; the team consisted of Tefera, Isaac Mutabai (CIMMYT), Wandera Ojanji (CIMMYT science writer/editor), Zachary Gitonga (CIMMYT Socioeconomics Program research associate), Addis Teshome (CIMMYT entomologist), Jackson K. Njana (Caritas-Embu), Everastus Okumu (Caritas-Homa Bay director), Otieno, Paddy Likhayo (Kenya Agricultural Research Institute, KARI), and Kimondo Mutambuki (KARI and EGSP-II Kenya national coordinator).

Wheat-for-Africa gains momentum

Written by on August 2, 2013. Posted in News.

Wheat-for-Africa Wheat was not a traditional staple in much of Africa, but urbanization, a growing middle class, and changing lifestyles are driving a rapid increase in demand for it. The urban and rural poor in Africa eat wheat, as do more prosperous consumers, and demand is burgeoning with rising populations. But leading wheat producing countries in Africa grow enough to meet at most 40% of their demand, so the continent imports more than US$ 15 billion-worth of grain each year.

Efforts to put wheat on the food and trade agenda in Africa recently came together at the Forum for Agricultural Research in Africa (FARA) meeting in Accra during 15–20 July 2013, when senior research, development, and policy experts met with representatives of CGIAR’s WHEAT research program to develop a strategy for promoting African wheat production. “The idea is to put together all the actors—the production side, the legislation, the demand and markets,” said Victor Kommerell, manager of the CIMMYT-led WHEAT Program. “Initially the strategy should focus on gathering more evidence of production and market potential, particularly regarding smallholder farmers’ chances to grow wheat as a cash crop, and then looking at future consumption and regional trade.”

The connections made at FARA in July followed the release of a key study in late 2012 at the ground-breaking conference Wheat for Food Security in Africa in Addis Ababa. Shortly after that conference, African Union agriculture ministers endorsed wheat as a strategic crop for Africa. Their heads of government, at African Union level, endorsed this a few months later.

“As a rough-and-ready estimate, most countries are fulfilling less than a quarter of their wheat production potential,” said CIMMYT socioeconomist Bekele Shiferaw, a key author of the wheat study. “There are many opportunities both to expand the area devoted to wheat and to increase yields from existing acreage.”

According to Shiferaw, this will require a fundamental change in the way participants look at the entire wheat value chain—from farm to market and from government office to donor boardroom. More research is needed on potential constraints on improved wheat production, including issues related to markets, land, labor, and how food aid is distributed.

Challenges affecting farming at different scales in different country contexts must be carefully considered—from small farms’ lack of mechanization, labor, and access to markets, to problems that have undermined large-scale wheat farming projects in Africa in the past. The aim is to ensure the best mix of small, medium, and large farms, as well as fitting options to the differing conditions of high- versus low-population density nations and current highland wheat-growing areas. The 2012 study focused on rainfed wheat, according to Kommerell. Irrigated wheat also has great potential—and unique challenges—in Africa. Release of a report by WHEAT on irrigated wheat for Africa is planned for September 2013.

Metal silos: a timely intervention in curbing postharvest losses

Written by on August 2, 2013. Posted in News.

Metal-silos The metal silo technology promoted by CIMMYT for maize storage has been hailed in Kenya as the ultimate solution to high maize postharvest losses caused by the maize weevil (Sitophilus zeamais) and large grain borer (Prostephanus truncatus), two major destructive insects of stored maize causing 30% losses and more than 80% damage to stored maize in Kenya and other countries in sub-Saharan Africa. The real losses are even bigger: when considering their environmental impact, the subsequent losses in nutritional value, industrial input, market opportunities, and the possible adverse effects on health of populations consuming poor-quality products, the need for interventions becomes even more apparent and pressing. “Addressing waste across the entire food chain must therefore be a critical pillar of future national food strategies,” said Ngari Nyaga, Crop Post Harvest Division head at the Kenyan Ministry of Agriculture, during the official opening of a national Stakeholders Workshop on Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP-II) held in Nakuru, Kenya, on 28 June 2013.

Tadele Tefera, CIMMYT entomologist and EGSP-II coordinator, outlined the workshop objectives: provide a forum to exchange ideas, information, and research outputs on EGSP-II among stakeholders in Kenya; raise awareness on postharvest losses and dissemination of effective grain storage technologies among stakeholders; consult stakeholders on policy environment and market issues for the purpose of refining, updating, and implementing EGSP-II; engage in policy dialogue on matters related to storage; find means of enhancing the technology adoption; and acquaint key stakeholders in the country with the technology and how they could enhance its adoption among the farmers they are supporting through their activities.

With the annual average production of about 33 million 90-kilogram bags, postharvest losses of about 20% translate into 540 million kilograms. “The metal silo technology being promoted by CIMMYT is a timely and critical element in the quest to promote food security,” stated Nyaga, pointing out that about two million Kenyans are considered food insecure. The technology will “lower postharvest losses, assist farmers to save on dusting labor, have healthy and tradable grains, and allow the farmers to wait for better prices instead of selling immediately after harvest for fear of losing their grains to weevils, larger grain borer, and poor storage.” The technology will also help to address an issue recently reported in a Ministry of Agriculture survey: the incorrect use of pesticides. According to Nyaga, metal silos will “lead to zero usage of storage pesticides, hence result in better health and stoppage of illegal use of restricted pesticides by farmers.”

As other forms of storage – traditional granaries and sisal and gunny bags – have proven ineffective, and chemical control unsuccessful (only half of Kenyan maize farmers use storage pesticides), Nyaga welcomed the decision of Kenya, Uganda, Tanzania, Rwanda, and Burundi to work together to develop technologies and policies to reduce crop postharvest losses in the region.

The workshop gave stakeholders a chance to update themselves on the project, appreciate the magnitude of the postharvest losses and the effectiveness of alternative postharvest technologies being used, and better understand the economics of postharvest management. It also provided the latest news from onstation trials on metal silo technology and super grain bags.

Tefera thanked the Swiss Agency for Development and Cooperation for funding EGSP II, a project aiming to reduce postharvest losses, enhance food security, and improve incomes of resource-poor farmers in Kenya.

Stepping up the fight against maize lethal necrosis in Eastern Africa

Written by on August 1, 2013. Posted in News.

MLN-Eastern-Africa1 “I can now identify with accuracy plants affected with maize lethal necrotic disease,” stated Regina Tende, PhD student attached to CIMMYT, after attending the CIMMYT-Kenya Agricultural Research Institute (KARI) “Identification and Management of Maize Lethal Necrosis” workshop in Narok, Kenya, during 30 June-3 July 2013. This was not the case a few weeks ago when Tende, who is also a senior research officer at KARI-Katumani, received leaf samples from a farmer for maize lethal necrosis (MLN) verification.

Tende is one of many scientists and technicians who experienced difficulty in differentiating MLN from other diseases or abiotic stresses with similar symptoms. According to Stephen Mugo, CIMMYT Global Maize Program (GMP) principal scientist and organizer of the workshop, this difficulty encouraged CIMMYT and KARI to organize this event to raise awareness about MLN among scientists, technicians, and skilled field staff; provide training on MLN diagnosis especially at field nurseries, trials, and seed production fields; train on MLN severity scoring to improve the quality of data generation in screening trials; and introduce MLN management in field screening sites to scientists, technicians, and skilled staff. The workshop brought together over 80 scientists and technicians from CIMMYT, KARI, and other national agricultural research systems (NARS) partners from Tanzania, Uganda, Rwanda, and Zimbabwe.

“It is important that all the people on the ground, particularly the technicians who interact daily with the plants and supervise research activities at the stations, understand the disease, are able to systematically scout for it, and have the ability to spot it out from similar symptomatic diseases and conditions like nutrient deficiency,” stated GMP director B.M. Prasanna.

Proper and timely identification of the MLN disease, which is a pre-requisite for effective control, is not easy. CIMMYT maize breeder Biswanath Das explains: “First of all, the disease is caused by a combination of two viruses, Maize chlorotic mottle virus (MCMV) and Sugarcane mosaic virus (SCMV). Secondly, its symptoms –severe mottling of leaves, dead heart, stunted growth (shortened internode distance), leaf necrosis, sterility, poor seed set, shriveled seeds– are not always unique to MLN but could be due to other fungal diseases and abiotic conditions.” The training workshop was one of CIMMYT/KARI initiatives to combat the disease threatening all the gains made so far in maize breeding. “With nearly 99% of the commercial maize varieties so far released in Kenya being susceptible to MLN, it is important that institutions like CIMMYT and KARI, in strong collaboration with the seed sector, develop and deploy MLN disease resistant varieties in an accelerated manner,” stated Prasanna. One of the key initiatives in this fight is the establishment of a centralized MLN screening facility under artificial inoculation for Eastern Africa at the KARI Livestock Research Farm in Naivasha. Plans are also underway to establish a network of MLN testing sites (under natural disease pressure) in the region to evaluate promising materials from artificial inoculation trials in Naivasha. The state of the art maize doubled haploid (DH) facility currently under construction in Kiboko will also play a crucial role in accelerating MLN resistant germplasm development. “The DH technology, in combination with molecular markers, can help reduce by half the time taken for developing MLN resistant versions of existing elite susceptible lines,” stated Prasanna.

MLN-Eastern-Africa2 During his opening speech, Joseph Ng’etich, deputy director of Crop Protection, Ministry of Agriculture, noted that about 26,000 hectares of maize in Kenya were affected in 2012, resulting in an estimated loss of 56,730 tons, valued at approximately US$ 23.5 million. Seed producers also lost significant acreages of pre-basic seed in 2012: Agriseed lost 10 acres in Narok; Kenya Seed lost 75; and Monsanto 20 at Migtyo farm in Baringo, according to Dickson Ligeyo, KARI senior research officer and head of Maize Working Group in Kenya.

While this loss represents only 1.7%, Ligeyo assured everyone that Kenya is not taking any chances and has come up with a raft of measures and recommendations: farmers in areas where rainfall is all year round or maize is produced under irrigation are advised to plant maize only once a year; local quarantine has been enforced and farmers are to remove all infected materials from the fields and stop all movement of green maize from affected to non-affected areas; seed companies must ensure that seeds are treated with appropriate seed dressers at recommended rates, they must also promote good agricultural practices, crop diversification, and rotation with non-cereal crops.

Throughout the workshop, participants learned about theoretical aspects of MLN, such as the disease dynamics, management of MLN trials and nurseries, and identification of germplasm for resistance to MLN. They also participated in practical sessions on artificial inoculation, and identification and scoring. Several CIMMYT scientists played an active role in organizing the workshop, including breeders Stephen Mugo, Biswanath Das, Yoseph Beyene, and Lewis Machida; entomologist Tadele Tefera; and seed systems specialist Mosisa Regasa. They were accompanied by KARI scientist Bramwel Wanjala, KEPHIS regulatory officer Florence Munguti, and NARS maize research leaders Claver Ngaboyisonga (Rwanda), Dickson Ligeyo (Kenya), Julius Serumaga (Uganda), and Kheri Kitenge (Tanzania). During his closing remarks, KARI Food Crops program officer Raphael Ngigi, on behalf of KARI director, urged participants to rigorously implement what they had learnt during the workshop in their respective countries or Kenya regions to help combat MLN at both research farms and farmers’ fields.

Commenting on the usefulness of the workshop, technical officer at KARI-Embu Fred Manyara stated: “I will no longer say I do not know or I am not sure, when confronted by a farmer’s question on MLN.”

“You go to the field.” U.S. Borlaug Fellows in Global Food Security

Written by on August 1, 2013. Posted in News.

When asked how you become a successful wheat breeder, Dr. Norman E. Borlaug replied, “Well, you go to the field. You go to the field again, and then you go to the field. When the wheat plants start to talk to you, you know you have made it.” The Nobel Peace Prize, the Congressional Gold Medal, and the Presidential Medal of Freedom were awarded to Dr. Borlaug for saving the lives of over one billion through his efforts. Borlaug’s legacy continues today through the U.S. Borlaug Fellows in Global Food Security Program at the Center for Global Food Security, Purdue University, providing graduate students the opportunity to “go to the field” and become successful scientists in their own right.

Funded by USAID, the Borlaug Fellowship provides graduate students the opportunity to collaborate with agricultural scientists in developing nations. The program fosters connections between scientists internationally, while furthering research and developing community around important agricultural themes, such as production, natural resource conservation, and development. With a focus on interdisciplinary and cross-cultural experiences, students benefit from the ability to practice their science on the ground in an international setting, preparing them to become important members of the global scientific community. Doctoral candidates Ariel N. Rivers of Pennsylvania State University and Sean M. Thompson of Texas A&M University were given the opportunity to “go to the field” during the 2013 field season in partnership with CIMMYT.

Of the dual-title program, Entomology and International Agriculture and Development at Pennsylvania State University, Rivers (pictured above) is mid-way through her six-month tenure at CIMMYT’s El Batán station. By studying the three practices of conservation agriculture —crop rotation, minimal soil disturbance, and retention of crop residues on the soil surface— Rivers hopes to better understand which of these practices augment beneficial insect communities and how. In high enough numbers, beneficial insects can contribute to pest control, nutrient cycling, and soil aeration, all of which are essential to agricultural production in low-input developing country agriculture.

Thompson (pictured right), of the Department of Soil and Crop Sciences at Texas A&M University, is working with Ground Penetrating Radar (GPR) to non-destructively assess wheat root biomass. This technology could allow for rapid, non-destructive assessment of populations and selection for traits undetectable by traditional methods. The primary objective of this research is to define the capability of GPR to phenotype below ground crop biomass, in the context of higher yield and quality stability in wheat during drought stress. GPR is one of the many field-based high-throughput phenotyping technologies being tested in CIMMYT’s Wheat Physiology program.

Both Rivers and Thompson plan to collaborate internationally after they complete their doctoral studies. “We have benefitted from the opportunity to practice that skill at CIMMYT,” they both agree. “Thanks to the example set by Borlaug, we are better prepared to take our science ‘to the field’.” Further information about the research or the U.S. Borlaug Fellowship in Global Food Security can be obtained by contacting the Purdue Center for Global Food Security.

CIMMYT’s work highly appreciated in Ethiopia

Written by on July 19, 2013. Posted in News.

Bekeles-Ethiopia The third Dialogue on Ethiopian Agricultural Development: Agricultural Research for National Development in the Face of Climate Change and Food Security was held during 4-5 July 2013 at the Haramaya University of Agriculture, Haramaya Harar. The Dialogue aimed to provide a platform for discussion on agricultural research for development and transformation of the sector for food security in Ethiopia.

The Dialogue was attended by World Food Prize Laureate and distinguished professor Gebissa Ejeta; two members of the agricultural standing committee of the Ethiopian parliament; alumni of the Haramaya University working at various national, regional, and international top-level positions, such as Berhane Gebrekidan, Sime Debela, Zemedu Worku, Ephirem Mamo, and Solomon Bekure; senior staff of Haramaya, Jimma, Hawassa, Dire Dawa, and Mekele universities; members of USAID’s Capacity to Improve Agriculture and Food Security (CIAFS); representatives of the Ethiopian Institute of Agricultural Research (EIAR); the Ethiopian Seed Enterprise; CIMMYT; and ILRI.

Panel discussions covered 60 years of agricultural research in Ethiopia; agricultural research at regional institutes and Ethiopian universities; perspectives of users of technologies generated by the national agricultural research system (NARS); linking research at international levels with NARS for greater impact; the Ethiopian experience; presentations on contributions of agricultural research in Ethiopia in terms of food security, foreign earnings, and climate change adaptation; reflections on dialogues and issues deserving special attention; and recommendations for enhancing efficiency and productivity of NARS.

Three CIMMYT scientists –Drought Tolerant Maize for Africa project leader Tsedeke Abate, Bekele Shiferaw from the Socioeconomics Program, and Bekele Abeyo from the Global Wheat Program– presented during the panel discussions. The presentations were followed by a Q&A session, during which CIMMYT was named as top-rated CG center in Ethiopia due to its contributions, along with other institutions and centers, to national agricultural education, research for development, and extension with outputs and impacts. CIMMYT was commended by the current and former EIAR directors general and deputy director general, as well as Haramaya University senior alumni and political representatives, for its long-standing relations and close collaborative work with the NARS in generating technologies, strengthening national capacities, and reaching farmers.

As the meeting assessed the gaps and constraints of agriculture for development, ways forward, and future continuity of the dialogue, Abeyo assured the participants that “CIMMYT is committed to continue and maintain its high-quality contributions to Ethiopia.”

Tackling toxins with aflasafe™

Written by on July 18, 2013. Posted in Features.

Introducing-aflasafe-to-farmers-300dpi-1 “All the maize for my home consumption comes from my aflasafe™-treated field,” says farmer Alhaji Al-Hassan from Nigeria’s Kaduna State. “When I take my maize to the market, buyers rush for it because the quality looks better. The grains look clean.”

First developed by the USDA and adapted for use in Nigeria by the International Institute for Tropical Agriculture (IITA) and the African Agricultural Technology Foundation (AATF), aflasafe™ is fast gaining ground across Africa as a non-toxic and affordable solution to one of the continent’s most serious food safety issues.

Aflatoxins are invisible, tasteless poisons produced by Aspergillus flavus, a mould commonly found infecting crops such as maize and groundnut, both in the field and in storage. While acute exposure to aflatoxins can kill, prolonged exposure leads to impeded growth, liver disease, immune suppression and cancer with women, children and the poor and most vulnerable. Aflatoxins also impact international trade, with African economies losing US$450 million every year from barred exports.

Competitive exclusion

Aflasafe™ works by ‘pushing out’ harmful, toxin-producing strains of A. flavus from the field through the deliberate introduction of indigenous but non-toxic, harmless strains – a process known as ‘competitive exclusion’. Heat-killed sorghum grains are coated with the non-toxic fungal strains and scattered by hand in the field prior to crop flowering. Field tests in Nigeria between 2009 and 2012 showed that use of aflasafe™ consistently reduced aflatoxin contamination in maize and groundnut crops by 80-90%.

In 2012, these findings led to the adoption of the biocontrol product by several extension agencies in Nigeria. IITA is currently constructing a low-cost manufacturing facility at its Ibadan campus in order to optimize the production process for aflasafe™ so that it can be taken up by other developing countries. The facility, which will be able to produce up to five tons of aflasafe™ per hour will also test commercialization models. Market linkages between aflasafe™ users and quality conscious food processors are also being developed, in collaboration with the private sector. With aflatoxin-contaminated maize in poultry feed being a major risk to animal health, links are also being developed with poultry producers.

Spreading the science

The success of aflasafe™ has led to an expansion in biocontrol research in Burkina Faso, Ghana, Kenya, Mali, Senegal, Tanzania, and Zambia. In Kenya, IITA has identified four non-toxic strains of A. flavus in locally grown maize, which are now being used to make a Kenya-specific product called aflasafe™-KE01. Researchers from the Institute are currently gathering efficacy data to determine where the product will be deployed. “We are happy with the innovative scientific solution which has done well in Nigeria,” says Wilson Songa, Kenya’s agriculture secretary. “The ball is now in our court, and we shall move fast… We needed the technology yesterday!”

Senegal is also developing its own version – aflasafe™-SE01, and IITA is optimistic that both Kenya and Senegal will have their own fully registered versions of aflasafe™ in two years, with Burkina Faso reaching the same point in three years and Zambia in four. Meanwhile, at the 2012 G20 meeting in Mexico, G20 leaders announced that aflasafe™ will be one of three initial pilot projects to be supported under the ‘AgResults’ initiative which aims to incentivize the adoption of agricultural technologies by the poor.

Affordable technology

IITA’s experience in Nigeria suggests that the cost of aflasafe™ – at US$1.5 per kg, with a recommended usage of 10 kg per hectare – is affordable for most farmers in the country. The Institute calculates that adoption of biocontrol with other management practices will reduce aflatoxin contamination by more than 70% in maize and groundnut and increase crop value by at least 25%, as well as improving the health of women and children.

With mass production and commercialization of the technology now imminent in Nigeria, the country’s Minister of Agriculture and Rural Development, Hon. Akinwumi Adesina, has been enthusiastic in his support. “For too many years we have neglected to regulate aflatoxin in the production of food,” Adesina says. “IITA has worked tirelessly to control aflatoxin and educate farmers on the harmful effects of this toxin. When we consider the potential benefits of aflasafe™, it is ultimately smallholders who stand to gain the most,” he concludes.

Curbing maize postharvest losses key to attaining food security in Kenya

Written by on July 15, 2013. Posted in News.

Kenya1-900x674 Kenya has experienced tremendous improvements in maize productivity, rising from 1,530,000 metric tons in 2002 to 3,420,000 in 2011. However, postharvest losses of up to 40% of the harvested grain pose great challenges to attaining food security, as about 80% of Kenyans live in rural areas and derive their livelihoods mostly from agricultural activities. With maize being the main staple crop and agriculture the cornerstone of Kenya’s economy accounting for 27% of GDP and producing over 75% of industrial raw materials, postharvest losses also pose a challenge to the economic development of the country. To address these issues, CIMMYT and the Kenya Agricultural Research Institute (KARI) organized the Improved Postharvest Management Training Course for Extension & Media Personnel in Nakuru, Kenya, during 26-27 June 2013.

“It is pointless to heavily invest in good agricultural practices, attain high yields, and lose 40% of it. Feeding the nation does not only require increased production but also a safeguard of all that is produced,” stated Leonard Ochieng’, Nakuru County director of agriculture, Ministry of Agriculture, presiding over the official opening of the course. The training aimed to build technical capacity in hermetic grain storage technologies, such as metal silos and hermetic bags, among Kenyan extension and media staff.

According to Tadele Tefera, CIMMYT entomologist and coordinator of the Effective Grain Storage for Sustainable Livelihoods of African Farmers Project, the course also intended to create awareness on the importance of grain postharvest management, help extension and media staff gain insights into different factors affecting postharvest management, and explain traditional and improved postharvest technologies and their use in grain loss reduction. According to Nakuru County Crops Protection Officer Hannah Oduor, there is always a surplus of maize in Trans Nzoia, Uasin Gishu, and Nakuru (the Rift Valley counties referred to as the granaries of Kenya), but the country is forced to import more nonetheless. “We cannot afford to continue importing maize, for this is a very expensive and unsustainable affair. Money for development is used to import food that we could have easily safeguarded with appropriate technologies like metal silos,” stated Ochieng’. The problem lies in high incidence of maize weevils and the larger grain borer combined with lack of effective storage technologies. “We need technologies like the metal silos for effective storage of this surplus to cater for periods of scarcity and for redistribution to other parts of the country where production is below consumption,” said Oduor.
Grace Kirui, the Nakuru deputy county director of agriculture in charge of extension and training, lauded CIMMYT and KARI for organizing the course. “It was in line with the Ministry of Agriculture’s renewed efforts in intensifying training and dissemination of appropriate pre- and post- harvest technologies to reduce both quantitative and qualitative losses,” she noted and then called on the trainees to use their newly-acquired knowledge to educate and create awareness among the wider public. “The technologies that reduce postharvest losses, to which you have been exposed during the training, will go a long way in improving food security, creating employment, increasing farm incomes, saving on foreign exchange, and alleviating poverty,” said Kirui. “I call upon you, agricultural extension officers, to work hand in hand with artisans to promote the technology during your normal extension activities, field days, exhibitions, and shows.”

Dealing with a deadly maize disease in eastern Africa: an update

Written by on July 12, 2013. Posted in News.

“Maize is Africa’s most important cereal crop, with more than 300 million of Africa’s most vulnerable people depending on it for their food security and livelihoods,” says B.M. Prasanna, director of CIMMYT’s Global Maize Program. “The emergence of maize lethal necrosis in eastern Africa has dealt a big blow to farming communities and maize-based seed companies.” Maize lethal necrosis (MLN) infection rates and damage can be very high, seriously affecting yields and sometimes causing a complete loss of the crop. Infected plants are frequently barren; ears may be small or deformed and set little or no seed. “There is no maize farmer in the whole of Nyakinywa area in Kaplamai division [Kenya] who has been spared by the disease, which is a danger to food security,” said area chief Francis Morogo in April 2013 in an interview with the Daily Nation newspaper.

Control of MLN is complicated by the fact that it is caused by a combination of two viruses that are difficult to differentiate individually based on visual symptoms. In the past two years, studies undertaken jointly by CIMMYT and KARI have confirmed the vulnerability of most pre-commercial and commercial maize germplasm to MLN under natural disease pressure as well as under artificial inoculation. However, promising CIMMYT inbred lines and pre-commercial hybrids with resistance or moderate resistance to MLN have been identified, which offers considerable hope to combating the disease through breeding efforts.

Together, CIMMYT and KARI are now planning to establish a centralized MLN screening facility for eastern Africa at the KARI Livestock Research Farm in Naivasha to facilitate reliable screening of maize germplasm and deliver MLN-resistant varieties to replace existing susceptible cultivars as quickly as possible. “Besides accelerated development and delivery of elite MLN-resistant products to farmers, our aim is also to build the capacity of regional institutions for developing robust breeding pipelines to incorporate MLN-resistant germplasm, and ensure that farmers have access to such products at the earliest opportunity,” Prasanna adds.
