Global demand for food is expected to grow rapidly leading up to 2050, and the ability to meet such demand is of the utmost importance in order to maintain food security. However, a recent study shows projected climate change threatens to compromise the world’s ability to meet this demand – especially in global cereal yields – as soon as the next 10 years, given that the bulk of the demand will occur in the next two decades.

The authors emphasize the importance of this information for organizations that deal in international food prices, stability and peace. The study “Getting caught with our plants down: the risks of a global crop yield slowdown from climate trends in the next two decades,” published in Environmental Research Letters by David Lobell, an associate director at Stanford University’s Center on Food Security and the Environment, and Claudia Tebaldi, a research scientist at the National Center for Atmospheric Research, used computer models to examine the potential impact of climate change on food yields in the next 20 years, particularly of wheat and maize.

The models combined global climate trends with data on weather patterns and crops in order to estimate the likelihood that global agriculture would be able to keep up with increased demand under a changing climate. According to the study, under natural climate shifts the likelihood that agricultural production will take a downturn in the next 20 years is very low, but when projected climate change is factored into the equation the results are quite different. “Climate change has substantially increased the prospect that crop production will fail to keep up with rising demand in the next 20 years,” stated Tebaldi. The study found that “because of global warming, the chance of climate trends over a 20-year period causing a 10 percent yield loss has increased from a less than 1 in 200 chance arising from internal climate variability alone, to a 1 in 10 chance for maize and 1 in 20 chance for wheat.” Maize faces a greater threat from climate change than wheat due to the fact that its main production areas are more geographically concentrated, meaning that “large regional trends can have more influence on global maize than wheat.” It is important to remember that one of the major assumptions of the study is that methods to adapt to climate change are not implemented on a large scale in the next 20 years, i.e. “the locations and seasons of maize and wheat production do not change.”

The study suggests that shifting production to cooler regions could help to offset the impacts of climate change on yield, but implies that at the present moment these shifts “are not occurring fast enough to significantly alter the global pattern of maize or wheat production.” While the likelihood of climate change having a devastating impact on wheat and maize yields is not very high, at one in 10 and one in 20 respectively, it is a concern that the odds are considerably higher under “human-induced global warming” than under “natural climate shifts.” It is for this reason that the authors recommend that anyone concerned with food security or international stability be aware of the potential risk climate change poses to global food production.

Go back to Conservation Agriculture

The primary purpose of the CIMMYT Global Conservation Agriculture Program (GCAP) is to co-develop sustainable intensification options for and with smallholder farmers in maize- and wheat-based farming systems in Latin America, Africa and Asia. Doing so contributes to CGIAR intermediate development outcomes on food security and poverty reduction. GCAP initially focused on conservation agriculture (CA) principles and high-quality, site-specific field agronomy research in a wide range of agro-ecosystems. Over the past few years, GCAP broadened its research portfolio in close collaboration with the CIMMYT Socio-Economics Program (SEP) to more holistically address sustainable intensification pathways and tackle adoption and adoptability of technical innovations.

In short, sustainable intensification of agriculture seeks to increase farming enterprises’ productivity in regard to land, water, labor and input productivity of farming enterprises in a socially equitable manner while preserving the natural resource base and the environment. This is easier said than done as the sustainable intensification paradigm requires understanding of the complex interactions (synergies and trade-offs) between bio-physical, environmental and socio-economic/market/policy factors at different scales/levels (field, farm, landscape, regions) in order to develop viable options in changing rural environments.

Not being ‘lost in, but dealing with complexity’ is GCAP staff members’ primary concern in order to achieve impact at scale and propose site- and farm-specific integrated adoptable solutions. This requires the use of systems research approaches and the development and use of conceptual frameworks. An example of this is the partnership with Wageningen University funded by the MAIZE and WHEAT CRPs.

Reaching impact at scale also requires strategic partnerships with a wide range of stakeholders – from advanced research institutions to government and private extension agencies, non-governmental organizations (NGOs) and the private sector. GCAP’s flagship projects in South Asia (CSISA), Africa (SIMLESA) and Mexico (MasAgro/TTF) were all designed specifically to use agricultural research for development (AR4D) to intensify farming systems. At the same time, these projects implement innovative approaches with effective methodological use of gender and innovation. A specific program to backstop gender and innovation in GCAP projects is led by the Royal Institute of the Tropics (KIT) of the Netherlands and funded by the MAIZE and WHEAT CRPs.

GCAP operates on the principles that technical innovations and scientific progress have great potential to help smallholder farmers when properly put in context. Therefore, a large part of the GCAP research portfolio is still focused on technical innovations and on the following themes:

• Conservation agriculture and its contribution to sustainable intensification (i.e. the Nebraska Declaration).
• Small-scale mechanization and labor saving technologies (i.e. the FACASI project).
• Decision support tools (DSTs) for site-specific nutrient/water management and precision agriculture/remote sensing for smallholders farmers.
• Effective use of information and communication technologies.

Genetic resources and bioinformatics are the responsibility of the Genetic Resources Program (GRP). It contributes to CIMMYT’s overall mission of increasing crop productivity to improve food security and improve livelihoods by storing, analyzing and disseminating the world’s largest collection of maize and wheat genetic resources, which are contained in the Wellhausen-Andersen Genetic Resources Center. The Center is one of only three ISO-certified seed banks in the world and the only one in North America. In its maize and wheat gene banks, seeds are held in trust for humanity under the framework of the International Treaty on Plant Genetic Resources for Food and Agriculture. Moreover, CIMMYT seed is made freely available to researchers and national agriculture institutions around the globe.

GRP scientists and staff work to provide healthy, viable seed and reliable information from the maize and wheat genetic resources collections and are responsible for more than 175,000 accessions. Their work enhances the use of maize and wheat genetic resources through research and technology, excellence in data stewardship and the creation of tools and methods that enable CIMMYT and its partners to readily use the available information.

The GRP consists of various units that work in tandem to achieve CIMMYT’S goals:

The Seed Health Laboratory staff members work on the safe exchange of wheat and maize seed around the world and are responsible for thousands of exchanges of maize and wheat samples annually.

The Biometrics and Statistics Unit provides service, research and training for CIMMYT and its partners, including methodology-model solutions, statistical analyses and experiment designs. A data stewardship approach strives for responsible stewardship and provides open access to CIMMYT’s seed data and the knowledge derived from it. Through this approach data standards, documentation, curation processes and timelines are established to coordinate the receipt, storage, manipulation and quality control of field and molecular data. It also enables accurate data documentation and storage throughout the analysis pipeline, versatile institutional databases and repositories, interfaces, output and informatic tools that are used by scientists and research assistants, reporting back the user requirements to CIMMYT’s software engineers in order to achieve continuous improvement of these tools.

CIMMYT recognizes that sustainably meeting the growing global demand for food may require the responsible use all of the available technologies, including genetically modified (GM) varieties of maize and wheat. Applying the practice of “sovereignty and safety first,” each nation will determine when and how GM crops will be used in their territory and this will require a legal and regulatory framework to be in place before any work can be done in this area (see CIMMYT’s guiding principles). CIMMYT is a member of “Excellence Through Stewardship,” which “promotes the universal adoption of stewardship programs and quality management systems for the responsible use and management of biotechnology-derived plant products.”

The Seeds of Discovery (SeeD) initiative systematically explores and mobilizes genetic variation in CIMMYT’s and other gene bank collections into maize and wheat breeding programs to increase productivity resistance to biotic and abiotic stresses such as heat, drought and disease.

The GRP’s activities can be summarized as:

• Conservation, characterization, distribution and use of genetic resources.
• Safe distribution of seed.
• Stewardship and ensuring open-access to CIMMYT’s data and derived information.
• Creation of quality, open-source software.
• Development and validation of new tools and methods for gene mining and crop improvement.
• Capacity building in all of these areas.

Silvano Ocheya is no stranger to the challenges developing countries face in improving agricultural production.

A native of Kenya, Ocheya’s interest in agricultural science started at an early age, growing up on a small farm that his mother ran by herself after his father’s death. “I saw how people back home are struggling, and their lack of knowledge, and thought if we can impact here, we will have an effect on a great number of families, and that is how the country can develop. We can’t think of industrialization until we have enough to feed our families,” said Ocheya.

Now, thanks to his excellent training and education in agricultural science and plant breeding as well as internships and research completed at CIMMYT, Ocheya is gaining the tools he will need to realize his dream of giving back. Ocheya received an undergraduate degree at the University of Nairobi, followed by an internship at CIMMYT-Kenya where he researched maize under his mentors, Dr. Dan Makumbi and Dr. Alpha Diallo. This research would eventually form the backbone of the thesis for his M.Sc. in genetics and plant breeding at the same university. Ocheya is currently pursuing his Ph.D. at Texas A&M University and is a member of Monsanto’s Beachell-Borlaug International Scholars Program, working with CIMMYT to research drought tolerance in wheat and resistance to wheat streak mosaic virus.

After earning his degree he hopes to utilize the skills he has gained to help improve agriculture in a developing country, perhaps his native Kenya. “That’s where I feel I am most relevant. I’ll make more impact if I apply the knowledge I’ve learned in a developing country, to make a difference in the lives of farmers and their families.” For Ocheya, the biggest challenges to agricultural production in Kenya are drought and disease, made even worse by climate change. These challenges inspire him to work to develop drought-resistant seed varieties that also give farmers high yields.

Ocheya also considers lack of information to be a setback for farmers in developing countries, especially for women. “We need to empower women by giving them information. There is a great deal of information out there but it is not accessible, including information like the right seed or amount of fertilizer to buy. Unless we empower them with that information, I think it will be very difficult to make a breakthrough in agricultural productivity,” said Ocheya. He cited the influx of mobile technology in developing countries as a potential platform to build agriculture-based apps that can be translated into local languages, providing a possible solution to this information gap. When asked about his plans for the future,

Ocheya mentioned that in addition to continuing his research he would also like to train young people using the knowledge he has gained. “If you look at the success of Norman Borlaug, for example, he trained thousands of scientists, and that’s how his impact was felt across the developing world. While he wasn’t able to do it himself (in Africa), he had people he could help and he trained them, and I think that’s the approach I will take.”

When traveling from Chimoio to Tete along one of the main roads in central Mozambique, one inevitably passes through Malomue, a small rural village in Báruè District. Since 2008, conservation agriculture (CA) technologies and improved drought-tolerant maize varieties have been promoted to farmers through various donor-funded projects, including a USAID-funded Feed the Future initiative.

In the past, farmers in the area would cultivate their land, clear the surface of all protective cover and burn the residue from the previous cropping season. The main food security crop in the area is maize, and due to lack of access to improved seed, lowyielding landraces were often planted. The introduction of improved agriculture technologies developed and tested by the Platform of Agriculture Research and Innovation (PARTI) and the Collaborative Research Support Program (CRSP) of the Sustainable Agriculture and Natural Resource Management Lab (SANREM) at Virginia Polytechnic Institute and State University (Virginia Tech) implemented in collaboration with the University of Tennessee, have brought significant change to Malomue. Farmers have been exposed to improved seed, fertilizers, improved weed management practices and more sustainable planting techniques based on conservation agriculture principles and practices.

Josè Leuane Dicane, a rural farmer from the community with approximately 15 hectares of cultivated land, said, “The first lesson I learned is that no fire should enter my plots, and I have managed to avoid burning grass from my neighbors.” Dicane also appreciates the reduced labor required when chemical weed control options and direct seeding techniques are used, as well as the increased moisture retention and fertility increases when legume crops are rotated and crop residues are kept on the soil surface. Improved drought-tolerant maize varieties, developed by CIMMYT and extended through Mozambican private seed companies, have further increased the yields on the fields of farmers such as Dicane. Dicane and his large family have become food self-sufficient. He has planted a garden where he produces higher value horticulture crops under small-scale irrigation, and has become an emerging commercial farmer by successfully selling his produce at a profit in the nearby town of Catandica.

The project has identified him as one of the most visionary and successful farmers in central Mozambique, worthy of sharing his experiences with others in the world. With support from USAID, Dicane and his wife were invited to go to the United States to attend a meeting of SANREM/CRSP. On 16 May, Dicane and his wife Judisse boarded an airplane on their way to the U.S. Neither had ever flown, stayed in a hotel or seen the world outside of Mozambique. This was the experience of a lifetime for them. During the SANREM/CRSP meeting on 20 May, they shared their new farming expertise with other participants and farmers. They spoke as if they had presented to an audience many times. Their very impressive report on the lives of rural farmers from Mozambique made a difference to many of the participants. The farmers from Malomue have been given a voice and the opportunity to describe the gradual changes in their lives. The changes might be small, but viewed through another lens, they are also groundbreaking.

A study funded by the Climate Change, Agriculture and Food Security (CCAFS) CRP involving three CIMMYT staff and an international team of scientists has just been published in the journal Nature Climate Change.

The authors of “Limited Potential of No- Till Agriculture for Climate Change Mitigation” conclude that claims relating to no-till agriculture’s role in slowing climate change may be overstated. No-till and reduced tillage are methods of establishing crops with minimum soil disturbance, in contrast to conventional tillage involving plowing or other cultivation practices.

No-till agriculture can deliver benefits in many, though not all, situations; these benefits include improved soil quality and retention of water in soil for use by crops. Therefore the technologies have a clear advantage in dry regions of the world. No-till usually leads to an increase in the concentration of organic matter near the soil surface. This is often interpreted as an absolute accumulation or “locking up” of carbon in soil, termed carbon sequestration; this has led to no-till being promoted as a form of climate change mitigation. This claim was recently restated in the 2013 Emissions Gap Report of the United Nations Environmental Programme (UNEP).

The review found that there was sometimes a genuine, but small, net accumulation of organic carbon in soil under no-till conditions compared with conventional tillage. However, much of the observed effects result from a redistribution of organic carbon with depth – extra organic carbon near the surface but less carbon in deeper soil. In addition, the soil sampling methods normally used tend to exaggerate the effect. Consequently the climate change mitigation achievable from converting to no-till agriculture is likely to be overstated. The authors of the new paper conclude that no-till agriculture has a role to play as one of the strategies contributing to global food security and the protection of soils, and thus to climate change adaptation (through building agricultural systems that are more resilient to climate and weather variability).

In regions where no-till or reduced tillage is agriculturally appropriate it should be promoted on these grounds, but not on the basis of equivocal evidence for climate change mitigation. Climate change mitigation is a small, but useful, additional benefit, not the key policy driver for its adoption. The review also states that those who promote no-till as a means of combating climate change frequently refer to the potential amount of additional carbon that may be stored, or sequestered, in soil. However, in the UNEP report and elsewhere, the barriers to adoption of no-till tend to be ignored.

The authors argue that there are numerous social, practical and infrastructural factors that can make its adoption difficult for farmers, particularly smallholder and resource-poor farmers in developing countries. These issues are being addressed by CIMMYT and others but progress in overcoming the barriers is often slow. Thus, even where there is a real potential for mitigating climate change, it is often difficult to achieve in practice.

Clare Stirling, CIMMYT-CCAFS Project Leader, said, “Overstating the climate change mitigation benefits of no-till is serious because it gives a falsely optimistic message of the potential to reduce climate change through altered agricultural practices.” She added, “Given that the climate change mitigation achievable through adoption of no-till is likely to be far less than claimed, there is even more pressure to decrease greenhouse gas emissions from other agricultural areas. In regard to wheat and maize – the two staple crops CIMMYT focuses on – improved nitrogen management is the key to low-carbon development.”

The Ethiopian government has embarked on a new initiative to improve nutritional security in the country through the widespread demonstration and use of quality protein maize (QPM), a type of maize that contains enhanced levels of protein. The new government initiative is a high-level endorsement of CIMMYT’s five-year Nutritious Maize for Ethiopia (NuME) project.

The principal goal of NuME is to improve the food and nutritional security of Ethiopians through the widespread application and use of QPM and improved agronomic practices that increase productivity. NuME project leader Adefris Teklewold said, “The new government initiative will play a major role in making the QPM technology and inputs available to a larger number of maize farmers living beyond NuME target woredas (districts).”

The key aspects of NuME are in the government QPM scale-out plan, “Strengthening Quality Protein Maize Promotion and Seed Supply Systems in Ethiopia.” The plan sets a target to increase the area producing QPM in Ethiopia to 200,000 hectares in 2015-2017, roughly 10 percent of the total land currently devoted to maize production in the country.

After critical review and enrichment by key stakeholders, the initiative was approved by Ato Wondirad Mandfero, State Minister of Agriculture, as “an initiative that links agriculture and nutrition.” Mandfero issued directives for the initiative’s immediate implementation in high-potential maize growing areas in the country, as well as the inclusion of QPM technology dissemination in the regular government extension program starting this year. The Ethiopian government’s agricultural extension program focuses primarily on assisting small-scale farmers to improve their productivity by disseminating research-generated information and technologies.

An alliance of key government institutions engaged in the agriculture sector, including the Ethiopian Agricultural Transformation Agency, the Ethiopian Ministry of Agriculture (MoA), other key development partners and CIMMYT support the scale-out plan and will work together to help execute a variety of initiatives to fulfill the food and nutritional security of Ethiopians.

The government initiative will create synergies with NuME and expand QPM through more field demonstrations and field days. NuME is achieving success with these methods, but the government expansion will make the QPM technology and inputs available to a larger number of maize farmers living beyond NuME project woredas. The government initiative will also create opportunities for more collaborators to participate in the effort and thus for more experience-sharing and impact on the ground. According to Teklewold, “The ultimate winner will be small-scale Ethiopian farmers who will have access to the technology through a wide variety of outlets and extension services.”

A sizable number of Ethiopian families depend on maize as their staple food source. However, a maize-based diet is generally deficient in the essential amino acids lysine and tryptophan. This can leave families — and particularly children — at risk for protein deficiency, especially in circumstances where intake of alternative protein sources is limited.

NuME promotes QPM, maize varieties developed by CIMMYT scientists through conventional breeding that contains enhanced levels of protein compared to common maize varieties. Two CIMMYT scientists (Dr. Evangelina Villegas and Dr. Surinder Vasal) who worked to develop QPM in the 1980s and 1990s were awarded the World Food Prize in 2000 for their work. QPM helps to fill the lysine intake gap in circumstances where maize is the dominant source of calories and protein and intake of alternative protein sources is limited. This analysis is strongly supported by various studies conducted in West Africa, Latin America and Asia, which concluded that children in vulnerable environments could benefit nutritionally from QPM consumption¹.

Key objectives outlined in the scale-out proposal include:

• Identifying options to enhance seed businesses and impact pathways by identifying constraints and opportunities in the seed value chain.
• Enhancing the capacity of regulatory agencies and developing systems to track improved seed use and impact.
• Demonstrating and creating awareness of seed companies and farmers regarding the performance and nutritional superiority of QPM varieties.
• Providing sufficient quantities of quality of QPM varieties to farmers in a sustainable manner.
• Supporting seed companies and community-based organizations to improve their capacity in seed production skills, post-harvest seed handling and seed business management to enable them to absorb available QPM varieties and increase quality seed.

The government initiative notes that five QPM varieties have already been officially released by Ambo, Bako and Melkassa Research Centers. Basic and adaptive research activities are being conducted concurrently by different centers of the Ethiopian Institute of Agricultural Research (EIAR) in collaboration with CIMMYT, to develop new improved QPM varieties adapted to different maize production environments and evolving stresses in the country.

As part of the initiative, a strategy will be developed to start QPM adoption by ensuring a sufficient QPM seed supply by:  improving access to credit and coordinated production of all seed categories (breeder, pre-basic, basic and certified) along the value chain; testing and demonstrating a stockist distribution plan for more efficient seed distribution; and providing seed business management and production training to emerging seed producers.

Target areas selected under the initiative include Agricultural Growth Program (AGP) woredas, most of which are in high-potential maize growing areas. An estimated 2.4 million people, comprising some 400,000 households in AGP woredas in Amhara, Oromia, SNNPR and Tigray regions, are expected to benefit from this initiative.

The NuME project is implemented by CIMMYT and funded by Canada’s Department of Foreign Affairs, Trade and Development (DFATD). Among CIMMYT’s partners helping to implement NuME are EIAR, the Sasakawa Africa Association/ Sasakawa Global 2000; MoA; the Ethiopian Ministry of Health; the Ethiopian Health and Nutrition Research Institute; Farm Radio International; Harvard School of Public Health; universities; agricultural, technical, vocational and educational training centers; and numerous seed companies.

Georgia has high soil fertility and good agro-environmental conditions for growing wheat, yet the country imports most of the grain it needs. To help make Georgia’s agriculture sector more self-sufficient, a small workshop and Wheat Field Day were held 7 June at Lomtagora Farm in Marneuli County.

The farm is a focal point in Georgia for the testing and adoption of winter wheat germplasm supplied by the International Winter Wheat Improvement Program, a joint project of the government of Turkey, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA). Several high-yielding varieties have been identified, multiplied and delivered to the farming communities in the country. During the field day, participants saw more than 70 varieties and breeding lines demonstrated on big plots and submitted seed requests for the ones they liked. Traditional Georgian bread was baked from different genotypes including the landraces, and samples were offered to the visitors.

Dr. Kakha Lashki, head of the farm, emphasized the need for technological innovations and varieties to improve farms and increase wheat production. Dr. Alexei

Morgounov of CIMMYT-Turkey presented some of those technological solutions. He also addressed the challenges facing wheat farmers globally. Dr. Ram Sharma of ICARDA-Tashkent spoke about the outcomes of regional cooperation with ICARDA and how they can be applied in Georgia.

This was the fifth year for the Wheat Field Day, and it attracted around 100 participants from across the country.

Dr. Thomas Lumpkin/CIMMYT Director General Mexico is seen by many as one of the strongest emerging economies, with a high GDP and strong purchasing power parity. Yet a commonly overlooked fact is that nearly 23 percent of Mexicans, some 27.4 million citizens, still suffer from food shortages and insecurity1. In late 2010, CIMMYT and the Mexican Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) launched the Sustainable Modernization of Traditional Agriculture project (MasAgro) to raise farm community living standards and foster sustainable food security through research, development, training and the transfer of technology —ultimately to make a difference to the lives of these millions.

From an initial budget of US$ 3 million to a budget of nearly US$ 20 million in 2014, MasAgro has been seen as a success and was described by the G20 Mexico Agriculture Group as “an experience that could serve as a model for coordinating research and development, innovation, transfer of technology, as well as public-private links in the agri-food sector.” Nonetheless, since the 2012 elections and change of government, as is typical, there has been a shift in priorities within SAGARPA with an increased focus on impact and downstream research. These changes also resulted in a changing vision for MasAgro, including new administrative rules. As a result, after months of extended negotiations, the technical annex between CIMMYT and the new SAGARPA administration was agreed upon by both parties, and signed last week.

For many across CIMMYT, the past few months have been a period of uncertainty, and I am grateful to all our staff for their patience during this difficult process. We are now entering a new phase of MasAgro with a broader vision and broader host of donors. MasAgro’s work, scientific research and innovation are integrated into CIMMYT’s strategy. MasAgro is an instrument to achieve a goal — to raise maize and wheat production in a sustainable manner in Mexico and perhaps other countries within Latin America — and this goal will remain beyond the parameters of a project’s lifespan.

CIMMYT’s mission — to increase the productivity of maize and wheat systems for global food security and reduce poverty — means that we must develop capacities across the entire value chain. Our challenge remains to accelerate the delivery of results but also to convince taxpayers, development agencies and policymakers that it is essential to invest in research. New crop varieties, good agronomic technologies and efficient value chains are the key drivers of growth in agricultural productivity.

Looking beyond the CIMMYT-SAGARPA relationship, CIMMYT is expanding MasAgro’s innovation and partnership model directly to Mexican state governments and to other Latin American countries.

For example, the Mexican state of Guanajuato has committed MX 10 million pesos (US$ 760,000) for 2014 to the Take It to the Farmer initiative, and there have been requests from the governments of Guatemala and Bolivia to replicate parts of the MasAgro model. Key innovations — ICT in agriculture, precision agriculture, post-harvest management, maize landrace improvement and conservation agriculture — are readily available for transfer to other countries. MasAgro and its many partners have achieved impressive results in just three short years (see box on page 2). Knowledge and insight gained from this pioneering project are serving as a blueprint for other CIMMYT projects and indeed other countries.

MasAgro’s Achievements and Impacts:

• 200,000 farmers are linked to MasAgro activities.

• 166 communities are engaged as part of the National Crusade Against Hunger.

• GreenSeekerTM technology has generated farmer savings in fertilizer application of US$ 1.7 million.

• 13 prototypes of agricultural machinery have been developed.

• 181 technicians have been certified in training on conservation agriculture.

• A network of more than 2,000 technicians is providing technical assistance to more than 60,000 farmers.

• Maize farmers applying MasAgro technologies have achieved an average yield increase of 25.4 percent. • More than 3,700 farmers are receiving agronomic and climate information via the MasAgro Móvil phone service.

• 40,000 ultra-high-density genetic profiles of wheat varieties and 20,000 of maize landraces have been generated.

• The largest search for heat and drought tolerance undertaken in any crop has been initiated, evaluating more than 70,000 wheat varieties for these traits.

• 4,000 landraces are being used to establish the relationship between genome-based information and traits such as drought tolerance and disease resistance. This is the most complete genome-wide association study (GWAS) in the history of maize research.

New Leadership for MasAgro

Dr. Bram Govaerts, Associate Director for the Global Conservation Agriculture Program, will assume the leadership of MasAgro, with responsibility for coordinating the evolution of related projects in Latin America. Bram joined CIMMYT in 2007 and since 2010 has been the leader for the MasAgro Take It to the Farmer initiative. Bram received his bachelor’s degree, master’s degree and Ph.D. from the Katholieke Universiteit Leuven in Belgium in bioscience engineering and agricultural production systems.

The “boom-bust cycle” of resistance genes refers to the widespread use of a single resistance gene that protects multiple varieties of a grain from a disease (boom). When the disease overcomes this resistance gene many varieties simultaneously become susceptible (bust). The wheat cultivar Mianmai 37, released in 2004, has always had high levels of resistance to yellow rust. However, in the 2013-14 season in China’s Chengdu basin, this cultivar has high levels of the disease, indicating a new rust pathotype has likely evolved. CIMMYT researchers are awaiting investigations by pathologists to confirm the presence of a new race. Mianmai 37 has been extremely popular in western China and has been used as the high-yielding check in the government-run provincial yield trials for several years. It is also used extensively in breeding programs throughout the region, but with the outbreak of this new pathotype, several breeders have reportedly lost between 60 percent and 80 percent of their breeding stocks. About 60 percent of entries in the government trials have also showed susceptibility this year, despite testing last year that showed they were all highly resistant. It is unknown which resistance gene has been overcome.

This new virulence comes on top of the V26 pathotype that first appeared in 2011-12. This pathotype took out the widely used gene Yr24/26, rendering many varieties susceptible. Of major concern was the apparent loss of resistance in the CIMMYT derived cultivar Chuanmai 42, the world’s first commercially released variety with a synthetic background, which showed a 15 to 20 percent leap in yield potential compared with the best non-synthetic lines in the region. Fortunately, Chuanmai 42 was segregated for resistance to V26, and reselections were quickly made and seed was bulked up so that this high-yielding variety can still be grown. The new yellow rust pathotypes have had virtually no effect on the CIMMYT nurseries in the region, where the vast majority of lines are maintaining their durability.

CIMMYT is collaborating with the Sichuan Academy of Agricultural Sciences (SAAS) and the Chinese Government State Affairs for Foreign Expert Administration, which partially funds Dr. Garry Rosewarne’s work, on various projects to improve China’s wheat yields. Over the past three years, in conjunction with Dr. Yang Ennian, a breeding program has been established that focuses solely on the use of adult plant resistances. This program is also virtually unaffected by the arrival of new pathotypes. This year, fixed lines were selected from the most advanced material, and these will be grown on small observation plots next year. Not only is the use of slow-rusting genes having an effect in this program, but the change from pedigree breeding to selected bulk generation advancement is resulting in much more efficient field operations. This, combined with extensive use of summer nurseries, will see an increase in efficiency of up to 50 percent in the breeding program.

Dr. Zhu Huazhong of SAAS is also using slow-rusting genes from CIMMYT, albeit for a different reason. Chinese material is generally completely susceptible to the wheat stem rust lineages of Ug99. Although stem rust is rare in China, Dr. He Zhonghu recognized that it would be prudent to employ a pre-emptive breeding strategy in preparation for a potential incursion of Ug99. To this end, Dr. Zhu has been making crosses between Sichuan material and several of the CIMMYT stem rust nurseries in China. Not only are these lines showing good yellow rust resistance in yield trials, there appears to be an increase in lodging tolerance.

CIMMYT’s Sichuan office also is testing machine harvesting of yield trials using a Chinese-built small plot harvester that costs about US $6,000, with hopes of implementing multi-location yield trials so lines can be more rigorously tested for yield stability. Collaborative breeding and research activities throughout China are also being driven by the Sichuan office, where slow-rusting germplasm is being distributed to selected key breeding programs to use in their hybridizations. Genetic populations have also been distributed for multiple environment testing against yellow rust, leaf rust, powdery mildew and fusarium head blight. Other research is focusing on quantifying the value of slow-rusting genes under epidemic conditions, using molecular markers to pyramid slow-rusting genes behind major seedling resistances and identifying novel resistance genes to yellow rust.

Varietal uptake by farmers is particularly difficult in China, where new seed can cost up to US$ 1,000 per ton. In a novel venture for this region, a seed company is being paid by the provincial government to grow another CIMMYT synthetically derived cultivar, Chuanmai 104, and the seed will be given directly to farmers in an effort to improve yields in the region.

Co-authored by three former CIMMYT scientists and officially released at the recent Borlaug Summit on Wheat for Food Security, this book concludes that further, sustainable intensification of agriculture can produce enough food to meet the demand of a growing world population to 2050. Achieving this will require greater effort and investment in agricultural research, development and extension, especially in the developing world.

Moreover, the increased-but-efficient (i.e., environmentally friendly) use of inputs will challenge scientists and farmers alike, particularly in high-potential, high-input environments. The authors focus on the major grains maize, rice, soybean and wheat, but touch briefly upon 20 or so other crops. They see special potential in Sub-Saharan Africa, where intensification has barely begun and there is large scope for closing the “yield gap” – the difference between farmers’ yields and those obtained on research stations.

The three authors coincided at CIMMYT in the late 1980s-early 1990s and afterward continued eminent careers in agricultural research for development. Byerlee headed socioeconomics research at CIMMYT and later led the team at the World Bank that produced the agency’s influential 2008 World Development Report Agriculture for Development. Edmeades coordinated maize physiology research at CIMMYT and, notably, studies on drought and low-nitrogen tolerance whose principles were applied to develop maize varieties that benefit an estimated 3 million households in Sub-Saharan Africa.

A wheat physiologist, Fischer served as leader of CIMMYT’s global wheat program and subsequently as a program manager in crops and soils at ACIAR in Canberra, Australia. His research publications are widely cited, he has received numerous science and development awards and, in 2007, he was elected a Member of the Order of Australia.

Dr. Thomas A. Lumpkin, CIMMYT director general, welcomed members of the CGIAR Fund Council to the El Batán campus on 9 May by promising them “a taste of the new CIMMYT.”

The Fund Council, a representative body of donors and other stakeholders, is the decision-making body of the CGIAR Fund. Its first onsite meeting of 2014 was held 7-8 May in Mexico City, hosted by Mexico’s SAGARPA, and many of the members visited the El Batán campus the following day for a series of presentations and tours that gave them a first-hand look at CIMMYT’s work. Lumpkin opened the day with an overview of CIMMYT’s unique history and its value to the international community, reminding the council members that in some developing countries, up to 90 percent of wheat and maize crops are from CIMMYT-derived seeds.

He also outlined some of the challenges and achievements in the regions where CIMMYT operates:

Africa

The continent is spending US $18 billion per year on wheat imports, Lumpkin said, but it is capable of growing enough wheat to meet all its demand with the right farming methods, training and policy environment. High temperatures and droughts brought on by climate fluctuations pose a severe problem, as do epidemics of new diseases. However, the quick response to the appearance of maize lethal necrosis (MLN) provides a model for responding to future diseases —thanks to generous funding from the Bill & Melinda Gates Foundation and ingenious work by CIMMYT scientists, we were able to begin releasing MLN-resistant germplasm in just two years.

Americas

MasAgro is an exciting initiative that has already posted impressive gains in Mexico’s national effort to increase grain production and reduce hunger. In the past year, CIMMYT has reorganized the program to align with the Mexican government’s National Crusade Against Hunger (Cruzada Nacional Contra el Hambre). In addition to ongoing work in Colombia, recent visits by government representatives of Bolivia and Ecuador mean that CIMMYT’s work in Latin America may expand.

South Asia

Constraints to germplasm exchange are a major challenge in the region, and the impact of climate change, population growth and water shortages is most acute here. CIMMYT’s expertise can help farmers make the necessary shift from water-intensive rice to cotton and maize. The Borlaug Institute for South Asia (BISA) is a bright spot in the region, already hosting field days that draw thousands of farmers. Lumpkin then shared some of the recent successes of the CRPs. From MAIZE, he singled out the Striga weed management program; the increase in maize seed fortified with essential nutrients; and small farm mechanization, with a particular focus on developing equipment that women farmers can comfortably use. Highlights from the WHEAT program include the adoption of zero-tillage in Kazakhstan and the wheat boom in Ethiopia, where yields have doubled in a decade.

From there, Lumpkin moved on to the future of CIMMYT, which will continue to undergo rapid growth and change. Exciting new programs and technologies will shape the way we fulfill our mission:

BISA

Launched in 2011 in collaboration with the Indian Council for Agricultural Research (ICAR), the institute now has full UN privileges and is working to improve the region’s agricultural practices. An example of the way BISA is helping Indian farmers is a technique that allows them to seed wheat into standing cotton, saving them a month of growing time. The president of Pakistan has agreed to co-fund the institute in his country, Lumpkin said, and the U.S. ambassador to Pakistan will fund new facilities and a farm.

International Wheat Yield Project (IWYP)

CIMMYT is part of a new international consortium that seeks to improve wheat yield by 50 percent within 20 years. The type of project that IWYP may fund is an effort to increase the photosynthetic efficiency of wheat from 1 percent to 1.5 percent. While the amount of change may seem insignificant, such a breakthrough would have enormous impact, allowing farmers to grow more wheat on the same amount of land using no more water, fertilizer or labor. Seed funding by MasAgro helped begin the funding pledges, which are currently at US $50 million.

Technology

Lumpkin singled out several technologies in use or in the pipeline that will increase yields and help mitigate the effects of climate change, water shortages and disease epidemics: • Doubled haploid maize inducer lines developed for the tropics.

• Use of helicopter- and blimp-mounted drone sensors to take quick, accurate measurements in the fields.

• The GreenSeeker system, which is already saving participating Mexican farmers US $100/hectare.

• Hybrid wheat – The quest for hybrid wheat varieties is so important to the world food supply that big companies have teamed up with CIMMYT to achieve that goal while still looking out for the developing world.

The past and future changes at CIMMYT can perhaps best be summarized by the evolving attitude toward our gene bank, which houses more than 175,000 accessions and is the largest in the world. In the past, Lumpkin said, the gene bank was regarded as a museum. But today, as through projects like Seeds of Discovery, CIMMYT scientists carefully analyze the small variations among the accessions, aware that those might lead to big discoveries. “The gene bank,” Lumpkin said, “is not a museum.”

The quiet Khokwe village in the Chanje Central Block in Chipata district, Zambia, was buzzing with activity on 2 April when six traditional chiefs visited the Sustainable Intensification of Maize-Legume Systems for the Eastern Province of Zambia-Africa Rising (SIMLEZA-Africa Rising) project.

Traditional leaders in African societies hold deep-rooted power in the communities, make important decisions on land use and distribution and guide villagers in times of change and uncertainty. Smallholder farmers in the Eastern Province face high labor costs and low labor availability and are confronted with the negative effects of climate variability, which require climate-resilient, low-cost alternatives to improve farm productivity. Conservation agriculture (CA)- based management practices, combined with drought-tolerant maize varieties, as suggested by SIMLEZA-Africa Rising, can reduce production costs and improve resource-use efficiency, productivity and profitability. Farmers from communities surrounding Khokwe warmly welcomed the six chiefs drawn from Chewa- and Tumbuka-speaking tribes of eastern Zambia.

Nyao traditional dancers known as “Gule Wankulu” and Ngoni dancers also joined the farmers in welcoming and entertaining the chiefs, who were accompanied by two representatives from the Ministry of Chiefs Affairs, village headmen, councilors and officers from the District Agricultural Coordinator’s Office (DACO). They were invited by the SIMLEZA-Africa Rising project team with representatives from CIMMYT, community agricultural committees, the International Institute of Tropical Agriculture (IITA), the Ministry of Agriculture and Livestock (MAL), the National Agricultural Information Service (NAIS), Total LandCare (TLC) and the Zambia Agricultural Research Institute (ZARI). SIMLEZA-Africa Rising is funded by USAID-Feed the Future. The chiefs visited trial sites in Khokwe, including a maize regional on-farm trial.

Farmers are directly involved in selecting the best maize varieties from the 20 that are being tested, which was emphasized in explaining participatory varietal selection. Most crops appeared stressed by drought, as the area had not received any rain for one month. ‘’These varieties are really drought-tolerant,’’ remarked Chief Magodi as participants left the maize regional on-farm trial to visit a maize mother-baby trial, where 12 drought-tolerant maize varieties are being tested. At the CA trial, the chiefs studied maize crops planted under zero tillage in rotation or intercropped with cowpeas.

The chiefs observed that maize in the ridge and furrow system was severely moisture-stressed while maize on the CA plots was still green and growing well. ‘’I never knew that there are such activities happening in our district,’’ exclaimed Chief Misholo from the Chiparamba block in Chipata district, adding that the visit was an “eye-opener” for him.

CIMMYT’s Walter Mupangwa highlighted environmentally-friendly products used on CA fields and the procedures farmers should follow when using herbicides. for weed control. Next to the CA field, new animal traction seeding equipment was showcased, including the animal traction direct seeder, Magoye ripper tines and a hand-held no-till planter. An agro-dealer from ATS Agro-Chemicals, part of the SIMLEZA-Africa Rising innovation network, displayed the herbicides and pesticides available for smallholder farmers in the region. Farmers were keen on interacting with the traditional leaders on farming-related issues. Main discussion points included the need to improve market links and information flow for soybean and maize crops.

Chief Mban’gombe encouraged farmers to diversify the crops they grow in the face of low prices for maize. The chiefs strongly advocated for SIMLEZA-Africa Rising to set up trials in their areas to help disseminate technology to more farming households within their jurisdiction. The chiefs’ visit is a major breakthrough for the SIMLEZA-Africa Rising project. The support of traditional leaders is a main driver of change toward more sustainable intensification.

In March, CIMMYT celebrated International Women’s Day and lauded the efforts of many. At CIMMYT, we are lucky to work with outstanding female colleagues. Perla Chávez Dulanto, associate scientist for the Global Wheat Program’s (GWP) physiology team, which is led by Matthew Reynolds, is one of those colleagues.

Chávez came to CIMMYT in 2012, inspired by the legacy of Dr. Norman Borlaug, who she describes as “a man who devoted his life and his science to help the poorest but was guided by his heart —a characteristic feature of great scientists and true human beings.” She was also motivated by the opportunity to be part of an interdisciplinary group working to improve food security and livelihoods. After earning a BSc in agricultural engineering at La Molina National Agricultural University in Lima, Peru, she worked for large-scale farm export enterprises and agribusiness, nongovernmental organizations and education-extension institutions. Yet Chávez, who is inspired by the landscapes she admired during her childhood, wanted to develop good crops for poor farmers.

“Though I was raised in Lima, my mother was from Chancay, a coastal city nearby and the largest provider of field crop commodities to Lima. From Chancay, you could see endless maize and potato crop fields with long rows almost reaching the beaches, listen to birds tweet and see whales or sea lions jumping into the water far beyond,” Chávez said. She knew she needed to learn about soil, physics, ecology, pathology and animal life. Chávez has had enough contact with farmers, both wealthy and poor, to realize there are large differences between their livelihoods. Peru produces wheat, barley and sorghum in mountainous areas. Wheat is important to smallholder and subsistence farmers but yields are only 2 to 3 tons per hectare due to the lack of improved materials and the prevalence of pests, disease damage and abiotic stresses like drought. Chávez said Peru and the Andean region could benefit from research, motivating her to continue with science.

She earned a master’s degree in entomology with complementary studies in integrated pest management and horticulture at La Molina and the Wageningen Agricultural University (WAU), The Netherlands. She earned a Ph.D. from the University of the Balearic Islands, Spain, and conducted research for the International Potato Center (CIP) in Peru on a project using remote sensing to detect biotic and abiotic stresses in potatoes. Chávez worked at CIP for eight years, where she had the opportunity to travel across Peru.

Chávez brings this expertise to the wheat physiology group and she says she is lucky for the support of her GWP colleagues. During her tenure at CIMMYT she has organized two courses on plant physiology for national staff at Ciudad Obregón, and edited and coordinated the English-Spanish translation of the manuals Fitomejoramiento Fisiológico volumen I y volumen II. She has also supported Amor Yahyaoui and Pawan Singh during field days in Toluca and coordinated visits by students and children at Ciudad Obregón.

“I am happy to do collaborative research within GWP and CIMMYT as a whole, which involves breeders, pathologists, physiologists, conservation agriculture experts and more,” Chávez said. “If we all work together we can move faster to discover and select genotypes with a very good combination of characteristics. Those genotypes — after several steps — can be released for farmers. We can make an impact on people’s lives.” Chávez will soon start a new stage in her life when she becomes a mother in May. She looks forward to sharing some of her other talents, such as drawing, painting and sculpture, with her baby boy.
