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.

EL BATAN, Mexico (CIMMYT) – Scientists involved in a major global initiative aimed at increasing wheat yields as much as 60 percent by 2050 got a recent boost when the U.S. government announced $3.4 million in new research funds.

Researchers affiliated with the International Wheat Yield Partnership (IWYP), focused on developing new high-yielding varieties of wheat to meet demand that will be generated by a projected 33 percent increase in population growth from 7.3 billion people today to 9.5 billion by 2050, will be eligible to apply for the grant money.

“This opens up new opportunities for scientists in the United States to provide invaluable input to the overall project of increasing yields, improving our potential to tackle this vital work to achieve global food security,” said Matthew Reynolds, wheat physiologist at the Mexico-based International Maize and Wheat Improvement Center (CIMMYT), one of the founding members of IWYP.

Awards for the new funds announced last Monday by Tom Vilsack, the U.S. agriculture secretary, will be made available through the U.S. Department of Agriculture National Institute of Food and Agriculture (NIFA) Agriculture and Food Research Initiative (AFRI).

“Wheat is one of the world’s most important staple crops, providing a significant amount of daily calories and protein throughout the world,” Vilsack said.

“By 2050, the demand for wheat as part of a reliable, affordable, and nutritious diet will grow alongside the world population, and continued wheat research will play an important role in ensuring its continued availability.”

IWYP, which targets partner investments of up to $100 million, supports the G20 Wheat Initiative in its efforts to enhance the genetic component of wheat yield and develop new wheat varieties adaptable to different geographical regions and environments.

CLIMATE RISKS

Wheat yields face threats from global warming. Findings in a report from the Intergovernmental Panel on Climate Change (IPCC) state that it is very likely that heat waves will occur more often and last longer throughout the 21st century and rainfall will be more unpredictable.

Mean surface temperatures could potentially rise by between 2 to 5 degrees Celsius or more, the report said.

“Wheat currently provides 20 percent of calories and protein consumed worldwide and current models show that a 2 degree increase in temperature would lead to 20 percent reduction in wheat yield and that a 6 degree increase would lead to a 60 percent reduction,” Reynolds said.

“If we have a 40 percent yield reduction due to climate change, the risks to food security will be increased because wheat production has to increase by 60 percent just to keep up with population projections.”

In addition to CIMMYT, IWYP members include Britain’s Biotechnology and Biological Sciences Research Council (BBSRC), Mexico’s Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), the U.S. Agency for International Development (USAID), the Grains Research and Development Corporation of Australia (GRDC), the Department of Biotechnology of India (DBT), Agriculture and Agri-Food Canada (AAFC), the Institut National de la Recherche Agronomique (INRA) in France and the Syngenta Foundation for Sustainable Agriculture (SFSA) in Switzerland.

Applications are due May 3, 2016 and more information is available via the NIFA-IWYP request for applications.

CIMMYT upgrades Pakistan’s national germplasm collection and distribution facility

Written by on December 18, 2015. Posted in News.

As a step towards modernizing and strengthening Pakistan’s national coordinated breeding programs, CIMMYT upgraded the seed storage facility of the National Agricultural Research Center (NARC) to meet international standards. The state-of-the-art facility offers a number of services such as damage control of stored wheat including avoiding both quantitative and qualitative losses, maintaining a record of incoming and outgoing seed, and tracking it until it reaches its destination.

Funded by the Wheat Productivity Enhancement Program (WPEP), the germplasm collection and distribution facility was formally inaugurated by Shahid Masood, member of the plant science division, Pakistan Agricultural Research Council (PARC), on 20 November 2015. CIMMYT Country Representative Imtiaz Muhammad, PARC Chairman Nadeem Amjad, NARC DG Muhammad Azeem Khan, and agricultural experts from national and international organizations graced the occasion with their presence.

Upon unveiling the foundation stone, Shahid spoke about the intention behind setting up the facility, which is to provide an international standard for maintaining the quality of wheat seed and seed of other crops and keep track of national and international germplasm.

Atiq Ur Rehman Rattu, National Wheat Coordinator, PARC, briefed the group on the system that will be used to stop seed mixing, fumigate, package the seed, and record services before distributing seed packets to collaborators across Pakistan.

“This establishment will substantially improve grain quality in Pakistan. It will connect the international seed sector with national partners to conduct trials after maintaining a record of the incoming material and trace it to the end delivery points,” said Imtiaz. The attendees acknowledged the efforts of the WPEP and especially of CIMMYT in enhancing Pakistan’s national breeding facilities. Azeem highlighted the importance of quality seed for increased productivity and said that the new facility will maintain and distribute pure, high-quality seed to national collaborators.

Agricultural mechanization highlighted at farmers’ field day in Bangladesh

Written by on December 18, 2015. Posted in News. 3 Comments on Agricultural mechanization highlighted at farmers’ field day in Bangladesh

Shahidul Haque Khan

To introduce modern agricultural machines to farmers of Jhenaidah, Bangladesh, a farmers’ field day (FFD) was held on 17 November 2015 at the M.K. High School, Kulfadanga, Maharajpur, Jhenaidah. The FFD was jointly organized by CIMMYT and IRRI under the USAID funded projects Cereal System Initiative for South AsiaMechanization and Irrigation (CSISA-MI) and Rice Value Chain (RVC).

Sk. Nazim Uddin, Mechanization Project Director at Bangladesh’s Department of Agricultural Extension (DAE), said that farmers need modern agricultural machinery and proper training, which is being provided by CIMMYT.

While addressing farmers, chief guest Hamidur Rahman, DAE Director General, pointed out that USAID funded agricultural projects are playing a vital role in introducing agricultural mechanization in Bangladesh and said, “Our population is increasing, whereas the cultivable land is decreasing day by day; we need to adopt complete mechanized systems in agriculture to meet the challenge of producing more food from less land. In this context, CIMMYT and IRRI are doing a great job that everybody should know about.” He also expressed his satisfaction with the public-private partnership initiated by CIMMYT’s CSISA-MI project. William J. Collis, CSISA-MI Senior Project Leader, expressed his hope that mechanization will push forward the agriculture of Bangladesh within the next 10 years and thanked the private sector for its continuous support of the country’s agricultural machinery sector.

At the field day, participating farmers learned about modern agro-machinery and mechanized cropping systems that help reduce tillage to conserve soil health, while saving time, labor, and expenses, and maximizing profit. Detailed discussions were held on how to make tillage options accessible at a lower price, and increase the use of machines through local service providers (LSP). A significant number of farmers expressed their willingness to become LSPs and earn extra income. They also requested subsidies for purchasing the agro-machines and starting their own business.

Farmers and guests later visited field plots where they witnessed demonstrations of several machines, such as a rice transplanter and reaper, a new planter called the hand crank spreader, and the power tiller operated seeder. These demonstrations were presented by private sector companies RFL, Metal, ACI, and Janata Engineering as part of their agro-machinery promoting activities. Afterward, a feedback session was conducted where farmers and LSPs expressed their opinions of the machines, their use and profitability.

Other special guests at the field day were Muhammad Nuruzzaman, Project Management-Coordinator, Economic Growth, USAID Bangladesh; Md. Sirajul Islam, Chief Scientific Officer, RARS, Bangladesh Agricultural Research Institute, Jessore; Subrata Kumar Chakrabarty, Project Manager, CSISA-MI, CIMMYT; and Kevin Robbins, Deputy Project Manager, CSISA-MI, iDE-Bangladesh. The program was chaired by Khairul Abrar, Additional Director, DAE, Jessore. Also present were Deputy Directors of DAE from Jessore, Magura, Jhenaidah, Chuadanga, Meherpur and Kushtia districts; the Chairman and members of Kulfadanga Union Parishad, local elites, school teachers, and large numbers of farmers.

CIMMYT maize varieties in high demand in Pakistan

Written by on December 18, 2015. Posted in News.

AbduRahman Beshir and M. Imtiaz

Pakistan imports more than 85% of its hybrid maize seed, which costs the country about US$ 60 million each year. Due to importation and other factors, the price of hybrid maize seed ranges from US$ 6-8 per kg, the highest in south Asia.

During a NARC-CIMMYT maize field day held on 25 November 2015, Muhammad Azeem Khan, Director General of Pakistan’s National Agricultural Research Center (NARC), said, “We are seeing valuable and precious contributions from the AIP [Agricultural Innovation Program] maize program which will help to lessen the dependency on imported hybrid maize seeds.” In his welcoming address to about 200 participants, the NARC DG mentioned the importance of reopening the CIMMYT office and reviving its activities after a gap of more than two decades.

CIMMYT’s maize activities in Pakistan are being implemented more widely under the recently launched AIP. M. Imtiaz, CIMMYT’s Country Representative and AIP project leader, welcomed the delegates and urged stakeholders to make an all-out effort to deliver maize varieties and hybrids particularly to resource-poor farmers.

Seerat Asghar, Federal Secretary for National Food Security and Research, reminded participants about the role CIMMYT played in helping Pakistan to become self-sufficient in wheat, and described the collaboration between Norman Borlaug and Pakistani scientists. He stressed that this type of collaboration must continue in order to achieve similar results in maize. The Federal Secretary also highlighted AIP’s maize activities, which have introduced a wide range of maize germplasm to Pakistan including vitamin A enriched, biofortified maize hybrids and stem borer resistant open-pollinated varieties (OPVs), among others.

Under the AIP maize program, which started its field evaluation work in February 2014, CIMMYT has evaluated about 100 set of trials consisting of more than 1000 maize hybrids and OPVs in all provinces and regions of Pakistan. In less than two years, the national agricultural research system has identified about 50 hybrids and OPVs suitable for further validation and commercial production. “Pakistan can be taken as CIMMYT’s new frontier for maize where positive impacts can be achieved sustainably,” said AbduRahman Beshir, CIMMYT’s maize improvement and seed systems specialist. “Such fast results are not happening inadvertently; rather, they are creating strong collaborations, and developing confidence and trust in national partners will result in meeting set targets effectively.”

AIP maize is a multi-stakeholder platform consisting of 20 public and private partners who are directly involved in Pakistan’s maize evaluation and validation network. The number of stakeholders is expected to increase as the program further expands product testing and deployment in different parts of the country. During the field visit, Umar Sardar, R&D manager at Four Brothers Seed Company, noted the performance of different maize hybrids and expressed his company’s interest in marketing white kernel varieties in KPK provinces. Similarly, Jan Masood, Director of the Cereal Crops Research Institute (CCRI), asked CIMMYT to allocate some of the entries for the benefit particularly of small-scale farmers in the mountain areas of Pakistan.

During the field day, CIMMYT principles for allocating products to partners were also announced. Ten private and public institutions have submitted applications to CIMMYT’s Global Maize Program to obtain CIMMYT maize germplasm for further validation and commercialization in Pakistan; those requests are now being reviewed by a panel of maize experts working with CIMMYT in Asia.

After visiting demonstration plots and trials, the chief guest, Federal Minister for National Food Security and Research Sikandar Hayat Khan Bosan applauded CIMMYT’s efforts to foster the production and delivery of affordable quality seed. In his concluding remarks, the Minister said, “The country is importing a huge amount of hybrid maize seed, which contributes to the high input price for maize farmers, particularly those with limited resources. We need to strengthen our local capacity especially in hybrid maize seed production in order to enhance availability, accessibility, and affordability of quality seeds to our farmers.” Minister Bosan also noted the role of PARC, CIMMYT, and USAID under AIP.

PARC Chairman Nadeem Amjad expressed his gratitude to all the stakeholders and organizers of this national event. Former PARC Chairman Iftikhar Ahmad and Shahid Masood, former member of PARC’s plant science division, received awards from the chief guest in recognition of their contributions under the AIP program.

Representatives of local and multinational seed companies, public research institutes, relevant government institutions, and USAID, as well as progressive farmers and policymakers attended the field day.

Balancing economy and ecology: agriculture vs. nature

Written by on December 17, 2015. Posted in Blogs.

“The prosperous still have a strong carbon footprint. And, the world’s billions at the bottom of the development ladder are seeking space to grow,” said Indian Prime Minister Narendra Modi during his opening speech at the COP21 climate talks in Paris, where world leaders recently gathered to come to an agreement that will slow and eventually stop global emissions of greenhouse gases that threaten the survivability of our planet.

Modi and other leaders have called for climate solutions that reconcile the right of developing countries to grow and environmental protection. If implemented correctly, a solution exists in the Intended Nationally Determined Contributions (INDCs), essentially “blueprints” for what post-2020 climate actions each country intends to take based on past contributions, future development needs, and opportunities to exploit alternative energies to fossil fuels. This allows the developing world to balance the need to grow while moving to clean energy by soliciting support through climate finance and other measures from developed countries.

Reconciliation of the right to develop and environmental protection must move beyond global dialogue, and be put into practice in every community struggling with the effects of environmental degradation and poverty.

Seventy percent of the “billions at the bottom” Modi refers to live in rural areas. A majority of these people suffer from land degradation – the long-term loss of an ecosystem’s services – due to climate change in combination with unsustainable crop and livestock management practices.

“Agriculture undermines the very resources it depends on,” says Frédéric Baudron, CIMMYT Systems Agronomist. “A new paradigm is needed to sustainably achieve global food security.” Baudron is a lead author of the chapter “Response Options Across the Landscape” in the recently released global assessment report “Forests, Trees and Landscapes for Food Security and Nutrition.”

Like the INDCs, landscape approaches may offer a compromise to achieve food production, natural resource conservation, and livelihood security goals, according to the report’s chapter. “Landscape configurations exist not only to minimize tradeoffs between conservation and food security and nutrition, but also to create synergies between these two goals,” argue Baudron and his fellow authors.

“Cultivated fields are not green deserts but may be part of the habitat of several species of importance for conservation,” says Baudron. “In many human-dominated ecosystems, some species can be dependent on agricultural practices such as extensive grazing in Europe or shifting cultivation in tropical forests. Conversely, biodiversity may contribute to crop and livestock productivity through the ecosystem services it provides, such as pollination or pest control.”

According to recent research conducted by CIMMYT and its partners in southern Ethiopia, diets of rural families living in diverse landscapes where trees are retained tend to be more diverse than diets of rural families living in simplified landscapes dominated by annual crops.

“Ongoing research conducted by CIMMYT and its partners in southern Ethiopia’s maize- and wheat-based farming systems suggests that maintaining trees and forest patches in production landscapes is not only good for the environment and biodiversity, but contributes to the maintenance of farming system productivity and resilience,” according to Baudron. “Farms embedded in diverse landscape mosaics also produce much more diverse and nutritious food.”

Landscape approaches are also closely associated with the concept of food sovereignty, which promotes the right of people to define their own food production and consumption at the local, national, and global level. Community level engagement with local food and agricultural systems also creates an ideal setting to engage communities for more sustainable management of food and agricultural systems.

“Ultimately, this is about acknowledging diversity as a fundamental property in the design of more sustainable farming systems,” says Baudron. “The question is: what configurations are optimal in different contexts? Answering this question will require a much higher level of partnership between conservation organizations and agricultural agencies.”

Direct seeding with two-wheel tractors increases wheat yield and saves time in the Ethiopian highlands

Agronomic practices that can close the wheat yield gap in the Ethiopian highlands are well known: row planting, precise fertilizer application, timely planting, etc. But their implementation generally increases the demand for human labor and animal draft power. And the availability of farm power in the Ethiopian highlands is stagnating, or even declining. The cost of maintaining a pair of oxen is becoming prohibitive for most farmers. Also, the rural population is aging as a result of young people migrating to the fast-growing cities of Ethiopia in search of more rewarding livelihood opportunities than farming.

Precision levelers are climate-smart machines equipped with laser-guided drag buckets to level fields so water flows evenly into soil, rather than running off or collecting in uneven land. This allows much more efficient water use and saves energy through reduced irrigation pumping, compared to traditional land leveling which uses animal-powered scrapers and boards or tractors. It also facilitates uniformity in seed placement and reduces the loss of fertilizer from runoff, raising yields. (Photo: CIMMYT)

Agriculture can help the world meet climate change emission targets

Written by on December 11, 2015. Posted in Director General's corner.

As world leaders meet in Paris this week to agree on greenhouse gas emission targets, we in the field of agricultural research have a powerful contribution to make, by producing both robust estimates of the possible effects of climate change on food security, and realistic assessments of the options available or that could be developed to reduce agriculture’s contribution to greenhouse gas emissions.

Agriculture is estimated to be responsible for about a fifth of global greenhouse gas emissions, and this share is increasing most rapidly in many developing countries; it may even increase as fossil fuels become scarcer and phased out in other sectors.

The solution being put forward today is climate-smart agriculture (CSA), which involves three components: adaptation, mitigation, and increased productivity. Adaptation is essential to cope with the impacts that cannot be avoided and to maintain and increase the global food supply in the face of resource constraints; mitigation can lessen but not prevent future climate changes.

Though CSA has been held up as an answer to the challenges presented by climate change, some would argue that it is no more than a set of agricultural best practices. Indeed, this is what lies at the heart of the approach.

In addition to making agriculture more efficient and resilient, the overall purpose remains to sustainably increase farm productivity and profitability for farmers. This is why over the last few years we have begun talking about the ‘triple win’ of CSA: enhanced food security, adaptation, and mitigation. But those who dismiss CSA as mere best practice ignore the value of seeing through the climate change lens, and guiding research to respond to expected future challenges.

To begin with, crop performance simulation and modeling, in combination with experimentation, has an important role to play in developing CSA strategies for future climates.

In a publication titled “Adapting maize production to climate change in sub-Saharan Africa,” several CIMMYT scientists concluded that temperatures in sub-Saharan Africa will likely rise by 2.1°C by 2050 based on 19 climate change projections. This is anticipated to have an extreme impact for farmers in many environments. Because it takes a long time to develop and then deploy adaptation strategies on a large scale, they warned, there can be no delay in our work.

This explains why CIMMYT is taking the initiative in this area, seeking support to develop advanced international breeding platforms to address the difficulty of developing drought-tolerant wheat, or bringing massive quantities of drought- and heat-tolerant maize to farmers through private sector partners in Africa and Asia.

Our insights into the causes and impacts of climate change lead us to important research questions. For example, how can farmers adopt practices that reduce the greenhouse gas footprint of agriculture while improving yield and resilience?

Colleagues at CIMMYT have challenged the idea that the practice of no-till agriculture (which does not disturb the soil and allows organic matter to accumulate) contributes significantly to carbon sequestration. I think it is important that we, as scientists, explore the truth and be realistic about where opportunities for mitigation in agriculture lie, despite our desire to present major solutions. It is also important to take action where we can have the greatest impact, for example by improving the efficiency of nitrogen fertilizer use.

Nitrous oxide emissions from agriculture have a climate change potential almost 300 times greater than carbon dioxide, and account for about 7% of the total greenhouse gas emissions of China. Improved nutrient management could reduce agricultural greenhouse gas emissions by the equivalent of 325 Mt of carbon dioxide in 2030. Overall, supply-side efficiency measures could reduce total agricultural emissions by 30%.

Some practices, such as laser land leveling, fall into both the adaptation and mitigation categories. Preparing the land in this way increases yields while reducing irrigation costs, the amount of water used, nutrients leached into the environment, and emissions from diesel-powered irrigation pumps.

Findings such as this offer real hope of reducing the severity of climate change in the future, and help us build a case for more investment in critical areas of agricultural research.

For climate-smart agriculture, the challenge of feeding more people and reducing emissions and environmental impact is not a contradiction but a synergy. We are improving our ability to predict the challenges of climate change, and proving that it is possible to greatly reduce agricultural emissions and contribute to global emission goals.

To face challenges such as climate change, we need high quality multi-disciplinary science combined with approaches to address problems at the complex systems level. Since my involvement in early large-scale studies, such as Modeling the Impact of Climate Change on Rice Production in Asia (CABI/IRRI, 1993), I am pleased to see that so much progress has been made in this regard and encouraged that our research is contributing to greater awareness of this vital issue and solutions to address it.

Interview with CIMMYT Director General Martin Kropff in Pakistan

Written by on December 8, 2015. Posted in Features.

From 23 – 26 August, 2015, CIMMYT’s Director General Martin Kropff visited Pakistan to attend the Agricultural Innovation Program’s (AIP) annual conference in Islamabad. Following the conference Kropff met with the CIMMYT team to talk about his observations, suggestions and way forward for continued impact in Pakistan.

Q: Is there room for improvement in the agricultural sector in Pakistan?

A: With an average wheat yield of nearly three tons per hectare, Pakistan’s agricultural sector is in a good position but there are still many opportunities to grow. As highlighted by the Federal Minister for National Food Security and Research, Sikandar Hayat Khan Bosan, technologies such as precision agriculture and hand-held technologies for soil testing, to increase yields present new opportunities. Many farmers’ I met at this year’s AIP conference are not using these improved technologies, and AIP can help ensure they have access.

Q: What is the role of public-private partnerships in agricultural development?

A: The private sector is essential for scaling up new technologies. CIMMYT, United States Agency for International Development (USAID), and heads of international and national companies in Pakistan and other AIP partners are discussing opportunities for future collaborations. This won’t be just a project on maize or wheat – but a full systems approach incorporating the entire value chain.

Q: How can we improve the seed industry’s capacity?

A: When I was Director at Wageningen University, we established an African Agribusiness Academy. Ambassadors from the university would organize groups of young entrepreneurs from across Africa to innovate and learn from our scientists, and vice versa. This type of partnership and co-learning could help AIP improve the industry and farmers’ lives as well as build relationships with the private sector.

Q: What has been your experience with Pakistani scientists and how can they continue to grow?

A: Pakistani CIMMYT scientists are at a really good level. At CIMMYT we are not just conducting research but also applying it in the field, and we need to keep innovating with Pakistan’s national centers and scientists. We also need to continue training and mentoring Pakistan’s future scientists – students from national universities that are an incredible asset to future development.

African maize farmers get support to mitigate impact of poor soils

Written by on December 3, 2015. Posted in Features.

NAIROBI, Kenya (CIMMYT) – As the global community marks World Soil Day, African smallholder farmers are contending with low yields due to low-fertility soils prevalent in most parts of sub-Saharan Africa. This situation has affected the food security of over 300 million people in the region who depend on maize as their staple food.

For the majority of these smallholder farmers, access to inputs like fertilizers to boost soil productivity has been restricted due to their high cost. The reality is that in Africa fertilizers cost up to six times more than in any other continent.

As a result, nearly three quarters (about 70 percent) of eastern and southern Africa’s maize is grown without fertilizers. As the International Maize and Wheat Improvement Center (CIMMYT) and partners work to give farmers a partial solution to this enor

mous challenge, efforts must be intensified to protect and maintain soil resources for sustainable development in Africa and the globe.

The Improved Maize for African Soils (IMAS) Project addresses the problem of low nitrogen in soils. Smallholder farmers can expect to harvest up to 25 percent more from new maize varieties developed by the IMAS project.

These varieties are nitrogen use efficient (NUE), which means they utilize more efficiently the small amount of fertilizer that farmers can afford to apply (typically less than 20 kilograms per hectare) compared to varieties currently on the market. The IMAS project is a public-private partnership involving CIMMYT, the Kenya Agricultural and Livestock Research Organization, South Africa’s Agricultural Research Council and DuPont Pioneer.

In two years – between 2014 and 2015 – 21 NUE hybrids were successfully released in Tanzania, Malawi, Mozambique, South Africa, Uganda and Zimbabwe. In addition, IMAS helped to increase seed production and distribution of three existing NUE varieties. According to Michael Olsen, IMAS Project Leader, these varieties are expected to reach approximately 84,000 farmers.

“Giving smallholder farmers practical solutions within their environmental conditions is a sustainable means to not only preserve soil resources but address key challenges in maize farming, which is a major livelihood for millions in Africa,” Olsen said.

Many of the released NUE hybrids carry additional traits that are important in the region, such as tolerance to drought and maize lethal necrosis, a devastating viral disease that is new in the region. Donasiana Limo, a farmer from Olkalili village in northern Tanzania, attests to the good performance of HB513, a drought-tolerant and NUE variety he planted during the main cropping season between January and March 2015.

“I did not do much to prepare my land because the rains came very late and ended early. With no fertilizer and failed rains, I did not expect to harvest the seven bags of 50 kilograms from eight kilograms of HB513 seed,” Donasiana said.

“If I had time to prepare my land and added fertilizer, the harvest would have been so much more.”

Many more farmers from this remote village have benefited immensely from HB513, including Valeria Pantaleo.

Sustainable solutions for African farmers need to be addressed during World Soil Day deliberations. Efforts to facilitate smallholders’ access to inputs like fertilizers are critical. In addition, to help arrest further soil deterioration emphasis must be placed on adopting correct agronomic practices and appropriate crop varieties available on the market that are well suited to different soil management systems.

Policymakers must formulate strategies for adopting universal practices that maintain soil resources and are adapted to farming environments across Africa. Kenya has already set the pace for maize breeding in Africa by including performance in low-nitrogen soils as a special prerequisite for maize variety release, a step that will help enhance healthy soils in Africa if adopted by other regulatory agencies.

Buena Milpa is the Sustainable Intensification Strategy for Latin America promoted by CIMMYT in Guatemala. It aims to foster innovation to reduce poverty and malnutrition, and enhance the sustainability of maize systems in the Guatemalan highlands.

Recently the Buena Milpa Project took an active role in the XX Lamb and VII Agrobiodiversity Fairs held in the Cuchumatanes Sierra, Chiantla, Huehuetenango, Guatemala, which brought together different social organizations and inhabitants from several departments (states) in the country’s western region.

Each year, the Association of Cuchumatan Organizations (ASOCUCH), Buena Milpa’s social institution, holds agrobiodiversity fairs where farmers exhibit and exchange varieties of maize, potato, bean, yam, and other crops that they grow on their farms. The objective is to promote the protection and conservation of agricultural and livestock diversity (especially of native maize). During the event, there were tables with displays on themes such as agrobiodiversity to support food security, climate change, and the environment.

During the fair, Buena Milpa made presentations on the work being done in the western region, where the general objective is to foster innovation to reduce poverty and malnutrition, while enhancing the sustainability of maize systems. Maize fields there are diversified by sowing amaranth, which is an important component of the region’s human diet. Amaranth tastings were held to emphasize that it’s also important to consume it. Informative materials were distributed and the participants were made aware of the importance of conserving and protecting native maize, in the Mayas’ native tongues (mam and popti’).

The Buena Milpa team also provided a space where girls and boys of different ages could take part in learning exercises with seeds of maize and other crops in order to teach them to protect and conserve nature and the native maize varieties. The reason for holding these activities for girls and boys was to allow the women to participate actively in the events. The social and economic reality of rural native women is complex, and they have no one to look after their children. For this reason, they are forced to take them along to these events, where they cannot pay full attention to the presentations because they are keeping an eye on their children.

These CIMMYT-led activities raised awareness among the region’s inhabitants of the importance of conserving and protecting native maize, adopting crop diversification, and conserving soil and water as a vital part of sustainable native farming in Guatemala’s highlands. The participants were also made aware of the value of women as agents of change, as well as the importance of fostering love for nature and protection of native seeds in young children.

Of maize farmers, coming calves, waxing oxen, and comely camels

About her last maize harvest in August 2015, Valeria Pantaleo, a 47-year-old wife and mother of four from Olkalili village, northern Tanzania, waxes lyrical: “I finally managed to buy a calf to replace my two oxen that died at the beginning of the year due to a strange disease.” Valeria relies on the oxen to plow her two-acre land.

Valeria beams as she looks at her newly acquired calf. From her joy, one would be forgiven for assuming that the village enjoyed a good season. More so since Valeria had a handsome harvest that gave her a surplus four 50-kilogram bags of maize which she sold to buy the calf.

But nothing could be further from the truth. Farmers from her village suffered from exceptionally low rains during the main planting season in January–February 2015. To make matters worse, the rains were very late and poorly distributed. And as Olkalili is semi-arid, scanty rains are the biggest challenge for farming. “The rains came in late February, fell for just one day and only came back towards end of March for a few days,” laments Valeria.

For this reason, many farmers did not anticipate any substantial harvest even from an improved new maize variety – HB513 – introduced to them by Anthony Mwega, a community leader. The variety is locally known as ngamia, Kiswahili for ‘camel’, a testimonial moniker coined by ngamia suppliers, Meru Agro Tours and Consultant Limited, to symbolize the variety’s proven resilience during drought, compared to other varieties.

A boon in drought

“We heard about this new seed from Mwega who also sells hybrid seeds. But since it was my first time to use it, and given that the rains were really low, I did not expect much,” explains Valeria. “This of course was a big worry for me and my family,” she adds.

However, despite the patchy rains, Valeria managed to harvest 10 bags of 50 kilograms each from the one acre on which she planted 10 kilograms of HB513 seed – half of her farm. “I got so much harvest and yet I planted this seed very late, and with no fertilizer,” exclaims Valeria. What is special about HB513 seed is that it is both drought-tolerant and nitrogen-use efficient (see Kenya equivalent). So, compared to other varieties, it not only yields more during moderate drought, but also utilizes what little nitrogen there is in the soil more efficiently. HB513 is one of the 16 hybrid varieties developed for Tanzania by the Drought Tolerant Maize for Africa Project. Besides giving farmers the benefit of nearly 49 percent more grain during moderate drought, this hybrid seed offers them an opportunity to make best use of what little fertilizer they can afford to apply.

More enriching than just meat, and reaching more

For Valeria, it means that her family has enough maize to last them until February 2016. And a ‘meaty’ more: at sowing and growing time, since Valeria did not anticipate such a good harvest given the devastation drought portends, she resolved to work extra-hard in her small grocery business to raise enough money for the calf. “Even then, it would have taken me at least nine months to raise enough money for the calf,” she recalls. “But thanks to my unexpected bonus maize harvest, I got the calf within five months! This was such a huge relief and a blessing to me. Now I will have the much-needed help to plow my land in the next planting season.”

Through partnership with the Improved Maize for Africa Project, in 2015 alone, Meru Agro produced and sold 427 tons of ngamia seed. The result? Approximately 65,000 smallholder farmers across major maize-growing areas in northern, southern highland, central and northwest regions of Tanzania including Valeria’s village have benefited from this variety. And the good news is that the plan is to reach even more farmers in the coming years with the ‘gospel’ of ngamia.

What is the bigger picture for Tanzanian maize farmers? Meru Agro has committed to increase production of ngamia seed in 2016. “We foresee a much higher demand for ngamia because farmers are now more aware of this seed. Our plan is to produce more than 1,000 tons,” says Chacha Watanga, Meru Agro Managing Director.

Meru Agro will not be working alone. CIMMYT, through its Drought Tolerant Maize for Africa Seed Scaling (DTMASS) Project, will continue to partner with Meru Agro and other small- and medium-scale seed companies to increase production of improved maize varieties such as ngamia to reach 2.5 million people in seven target countries across eastern and southern Africa (Ethiopia, Kenya, Malawi, Mozambique, Tanzania, Uganda and Zambia). “Within its three-year lifespan, DTMASS will support production of about 12,000 metric tons of certified seed to reach smallholders who need this seed to overcome the big challenge of drought,” adds Tsedeke Abate, DTMASS Project Leader.

EL BATAN, Mexico (CIMMYT) – Scientist Ravi Singh has been named a Fellow of the American Association for the Advancement of Science (AAAS) this week for his “distinguished contributions to the field of agricultural research and development, particularly in wheat genetics, pathology and breeding.”

Singh, who leads wheat improvement and rust resistance research at the International Center for Maize and Wheat Improvement (CIMMYT), is among 347 members awarded the honor this year by the scientific organization AAAS, which also publishes the journal “Science.”

The fellows were honored due to their scientifically or socially distinguished efforts to advance science or its applications.

During more than 30 years at CIMMYT, Singh has made significant contributions to enhancing food security throughout the developing world. His work has led to the application of durable resistance to control fungal wheat rust diseases, which result in almost $3 billion in crop losses a year. As a result of this work, many farmers do not need to protect their crops with costly fungicides, boosting the potential for organic farming.

Singh’s research has shown that globally effective, durable resistance to leaf, yellow and stem rust fungi in wheat involves interactions of slow rusting genes that have additive effects and that the accumulation of four or five of these genes results in a level of resistance comparable to immunity.

His research group has identified 11 diverse slow rusting genes and discovered that some slow rusting genes confer partial resistance to multiple diseases. These include genes Lr34/Yr18/Sr57/Pm38, Lr46/Yr29/Sr58/Pm39, Lr67/Yr46/Sr55/Pm46 for leaf, yellow and stem rusts, and powdery mildew, respectively.

Singh was a co-investigator for research that led to the cloning of pleiotropic geneLr34, a landmark in understanding the genetic mechanism for slow rusting resistance that is conferred by a unique gene belonging to ABC (ATP Binding Cassette) transporter of PDR (Pleiotropic Drug Resistance) subfamily.

His research team have identified and designated 25 genes in wheat, including: Sr8b, Sr55, Sr57 and Sr58 for stem rust resistance; Lr31, Lr46, Lr61, Lr68 and Lr72 for leaf rust resistance; Yr18, Yr27, Yr28, Yr29, Yr30, Yr31, Yr46, Yr54 and Yr60 for yellow rust resistance; Pm39 and Pm46 for powdery mildew resistance; Bdv1 for barley yellow dwarf virus tolerance; SuLr23 for suppression of leaf rust resistance; Sb1 for spot blotch resistance; and Ltn1, Ltn2 and Ltn3 for leaf tip necrosis.

More recently, his research group identified various Quantitative Trait Loci that confer slow rusting resistance to stem rust including the highly virulent Ug99 stem rust race-group.

Singh was also part of the global research team that isolated the wheat gene Lr67, revealing how it hampers fungal pathogen growth through a novel mechanism. CIMMYT scientists created and field tested genetic mutations of Lr67, to pinpoint the gene’s exact location in the wheat genome.

CIMMYT-derived wheat cultivars with durable rust resistance cover more than 25 million hectares in the developing world, contributing billions of dollars through enhanced yield potential and yield savings in epidemic years.

Singh’s research team has also developed various widely grown current wheat varieties in various countries with enhanced grain yield potential of five to 15 percent combined with heat and drought tolerance and good processing quality.

More recently, the team also initiated breeding wheat with enhanced levels of grain zinc and iron concentration in grain, which are being tested in India and Pakistan to improve the nutrition of women and children with chronic micronutrient deficiency.

Singh has penned 200 peer reviewed journal articles, 26 book chapters/extension publications, 80 published symposia, and 212 symposia abstracts that he has authored and co-authored.

He has also received the “Outstanding CGIAR Scientist Award,” the 2015 China Friendship Award, and awards from China’s provincial governments in Sichuan, Yunnan and Xinjiang. He is a fellow of the American Society of Agronomy, Crop Science Society of America, American Phytopathological Society and the National Academy of Agricultural Sciences of India.

Singh and the other new AAAS fellows will be presented with an official certificate and a gold and blue rosette pin in February during the organization’s 2016 annual meeting in Washington, D.C.

Study reveals challenges in southern Africa’s soil carbon uptake

Written by on November 23, 2015. Posted in Features. 1 Comment on Study reveals challenges in southern Africa’s soil carbon uptake

A new study led by ETH Zürich graduate Stephanie Cheesman, along with CIMMYT senior agronomist Christian Thierfelder, Neal S. Eash from the University of Tennessee, Girma Tesfahun Kassie, ICARDA, and Emmanuel Frossard, professor at ETH Zürich, found limited increase in carbon sequestration under conservation agriculture (CA) after up to seven years of practice. In this interview, Cheesman tells us why carbon sequestration is such a complex issue in Southern Africa and what this study reveals about how it can improve.

Q: Why is increasing soil carbon important?

A: Besides the hype about sequestering carbon to contribute to climate change mitigation, carbon is an integral part of soil organic matter (also referred to as “humus”), which is possibly the most well-known fertility component of a soil. Soil carbon has strong influence on soil structure, water infiltration, as well as the capacity of the soil to retain water and nutrients that are required for plant growth. Degraded soil has only a little soil carbon and, hence, low fertility and nutrient- (and water) holding capacity.

Q: What were you hoping this study would reveal?

A: Although the study trials had been running for only seven years, I was hoping to show a clearer trend towards an increase in soil carbon under CA as compared to conventional practices (CP) in Southern Africa. We were surprised that, in most cases, the carbon under CA was at the same level as the conventional control treatment, with a few exceptions. Nevertheless, this is one of a very few studies where soil carbon stocks in CA systems have been analyzed across a wide range of Southern African agroecologies. I am now very happy to share this data with the wider research community.

Q: What factors limit carbon sequestration in Southern Africa?

A: There are a range of factors that limit carbon sequestration. Our findings suggest low productivity to be one of the main bottlenecks. Farmers have to decide if they should feed the crop residues to the soil or to their livestock. The long dry season from May to November and high temperatures further increase the mineralization of soil carbon, which can be twice as much as in temperate regions. Another factor that may limit carbon sequestration is the limited use of other strategies such as the integration of legumes or agroforestry species as intercrops in maize-based systems.

Q: Given the findings of this study, how can we increase soil carbon in Southern Africa in the future? Is conservation agriculture necessarily the answer?

A: Unfortunately, our study lacks initial carbon stock measurements, as this was tested on a very large set of on-farm trials and we never had enough financial resources to continuously test this from the onset. We could compare the difference between CA and CP but not how carbon stocks changed over time in the respective systems. Although some of the trial sites were up to seven years old, this is a comparably short time to increase the level of carbon in such environments. From other long-term studies (mainly in the Americas), we know that tillage-based agricultural systems decrease carbon stocks. Thus, I would say that a system like CA where tillage is reduced and residues are “fed” to the soil will more likely maintain soil carbon and maybe gradually increase it in the longer term. Tillage-based agricultural systems also have much higher soil erosion loads which further decreases carbon, so CA is definitely an answer to reduce soil degradation.

CIMMYT’s mission is to “sustainably” increase the productivity of maize- and wheat-based systems to reduce poverty and hunger. By combining improved varieties with sustainable intensification practices, CIMMYT does its best to give smallholder farmers options to improve their productivity and livelihoods. Feeding the soil with residues is one strategy to maintain or gradually increase soil carbon but we should not forget the immediate needs of farmers.
