For decades, rice stubble has been burned in India to clear fields and prepare for wheat sowing. The easiest way of getting rid of rice crop residue is to burn it in bulk, but this poses a serious threat to the entire biosystem, from soil nutrition to human health. Deteriorating soil health results in lower crop yields, increased dependence on fertilizers, and increased water volume requirements for irrigation, all of which have negative impacts on farmer incomes.
“Earlier when rice harvesting was manual, crop residues were taken out from fields and farmers benefited from selling them,” explains M.L. Jat, principal scientist and systems agronomist at CIMMYT. “Later, when agriculture included more mechanical operations for harvesting with the increase in the production to the tune of millions of tons, crop residue became a hazard in terms of disposal that would involve huge money, labor, and logistics.”
Farmland distributions are rapidly evolving in many parts of sub-Saharan Africa, as data from the World Bank’s Tanzanian Living Standards Measurement Study-Integrated Surveys in Agriculture (LSMS-ISA) shows. Between 2009 and 2013, farms under 5 hectares have increased in absolute numbers – from 5.4 to 6.1 million – as smallholdings became increasingly fragmented due to demographic and land inheritance patterns. But farms greater than 5 hectares also grew in number, and their share in the rural landscape, in terms of land area, grew quickly. The share of total farmland held by “small” farms of less than 5 hectares declined from 62% to 56% over the period while the share of farmland under farms of 10 or more hectares grew by 6%. So, what are the implications of such rapid changes in farm structure and concentration of land under larger farms?
CIMMYT spatial economist Jordan Chamberlin is using household survey data in innovative ways to reveal how changing patterns of land access and farm size distributions are influencing farmers’ livelihoods. He is investigating whether medium- and large-scale farms generate benefits for nearby smallholder farmers. In a case study in Tanzania, Chamberlin and his colleague, T.S. Jayne, estimated how rural incomes are affected by land concentration measures, such as the Gini coefficient, after controlling for other household and geographical factors, including market access, population density, and rainfall.

Another important finding was the lack of evidence for positive impacts of farmland concentration when such concentration was measured as the share of land in farms of 10 or more hectares. The intuitive explanation of this result is that the larger the farm, the less likely it is to generate benefits for surrounding smallholders. This may be because medium-scale farms, relative to larger commercial farming enterprises, are more likely to employ labor from surrounding households, and may also provide services such as mechanized traction.
More research is needed to identify these spillover mechanisms, and to understand the conditions under which larger farms generate positive impacts for smaller neighbors. As the farmland landscape is evolving quickly in sub-Saharan Africa, understanding these mechanisms could be instrumental to drive more inclusive rural development. Such research could help to add nuance to the current debate in agricultural and land policy circles about whether the de facto expansion of medium-scale and larger farms are a boon or a threat to the smallholder majority within the region’s agrifood systems.
This research was carried out in collaboration with T.S. Jayne, Michigan State University, with support from USAID’s Feed the Future Innovation Lab on Food Security Policy, the BMGF-funded Guiding Investments in Sustainable Agricultural Intensification in Africa (GISAIAA) initiative, the CGIAR Research Program on Policies, Institutions, and Markets (PIM).

Research partners to develop new maize hybrid seed production system to help smallholder farmers access modern, high quality maize hybrid seed.
Pretoria, South Africa, 26 October 2018– An initiative launched in 2016 seeks to provide African smallholder farmers with better quality and high yielding hybrid maize seed. The Seed Production Technology for Africa (SPTA) initiative strives to improve seed production systems to ensure that high-quality hybrid maize seed is available to smallholder farmers, as well as to deliver new hybrids with a high yield potential adapted for low fertility areas common in sub-Saharan Africa (SSA).
SPTA will utilize a technology provided by Corteva Agriscience, and implemented by the Agricultural Research Council of South Africa (ARC) alongside the International Maize and Wheat Improvement Center (CIMMYT), and the Kenya Agricultural and Livestock Research Organization (KALRO). Funded by the Bill & Melinda Gates Foundation, the four-year initiative will cost US$ 6.4 million.
“As Africa faces significant challenges of low maize yields, climatic extremes and variability, costly farm inputs, threats due to pests and diseases, and growing demand for food, it is critical to provide smallholder farmers with access to high quality and stress resilient modern maize hybrids to allow them to increase yields and incomes,” said Kingstone Mashingaidze, Senior Research Manager at ARC.
The SPTA process will address pressing seed production concerns in the region that include insufficient genetic purity due to pollen contamination resulting from improper or incomplete detasseling practices. As a result, small and medium seed companies are expected to produce greater volume of hybrid maize seed at lower cost. Partner seed companies in the region will access the technology royalty free.
Maize productivity in Africa lags behind other maize producing regions, and through SPTA more smallholders will improve their yield. Average maize yield in much of Africa is approximately 2 metric tons per hectare, which is less than 20 percent of the yield level in more productive parts of the world. Farmers cannot access or afford high quality seed. Only 57 percent of the SSA maize growing area is planted with recently purchased seed; a lot of hybrids grown in the region are obsolete – 15 years or older compared to an average of less than 5 years in highly productive regions. In many situations, seeds of these older varieties are no longer suited for the climate and cropping environments that exist today.
Hybrid maize seed delivered through SPTA will have higher yield in low fertility environments. This will enable resource-constrained farmers to harvest more despite limited inputs like fertilizer. This means stronger livelihoods coupled with improved professionalism in the maize seed value chain for farmers, seed companies, consumers, and governments to deliver a more food-secure future.
SPTA originated from the Improved Maize for African Soils (IMAS) project that concluded in 2015. IMAS focused on developing maize hybrids that could use nitrogen fertilizer more efficiently to deliver higher yields under low fertility conditions prevalent in Africa. The IMAS project was funded by the Bill & Melinda Gates Foundation together with the United States Agency for International Development.

DES MOINES (Iowa) — Hundreds of food and agriculture leaders from around the world gathered last week in Iowa, USA, for the 2018 edition of the Borlaug Dialogue. Much of the conversation this year was centered on how to “take it to the farmer,” as Norman Borlaug famously said. Experts discussed how to build sustainable seed systems, grounded on solid science, so improved varieties reach smallholder farmers.

Louise Sperling, senior technical advisor at Catholic Relief Services, presented a study on the sources of seed for smallholder farmers in Africa. She explained that 52.2 percent of households receive new varieties, but only 2.8 percent of the seed comes through agro-dealers. The biggest source is local markets and own stock, the so-called informal channels.
Quality and variety of seed should be the focus, emphasized Jean Claude Rubyogo, seed systems specialist at CIAT. In his view, we need to integrate formal and informal seed distribution channels, using the competitive advantages of each.
“When we take good seed, we address all African soil,” said Ruth Oniang’o, board chair at the Sasakawa Africa Foundation. Oniang’o explained access to financing is a major hurdle for smallholders to access better seed and other innovations. In her view, current financial products are inadequate. “Why should we get a farmer to pay 20 percent interest rates on a small loan?”
B.J. Marttin, member of the managing board of Rabobank Group, recommended financial institutions to partner with farmers through every stage, from production to sale, so they better understand risk and the whole value chain. Simon Winter, executive director of the Syngenta Foundation for Sustainable Agriculture, captured the main points from the session on financing for agricultural entrepreneurs. “We have to have the farmer at the center. The farmer is the ultimate customer,” Winter said. “If we are not serving farmer needs, we are not really solving the problems.”
Research to feed the world
The 2018 Global Agricultural Productivity (GAP) Report, presented at the Borlaug Dialogue, shows the growing gap between future food supply needs and agricultural production, particularly in low-income countries. To meet the projected food needs of nearly 10 billion people in 2050, global agricultural productivity must increase by 1.75 percent annually, the report states, but has only increased 1.51 percent annually since 2010.
A plenary session led by CGIAR explored the role of research in tackling this and other complex challenges. “We have to talk about food and agriculture research,” said former U.S. Secretary of Agriculture Dan Glickman. People need to understand research is not abstract academic knowledge, but rather useful innovation that goes “from the farm, to the table and to the stomach,” he explained.
“Innovation, no matter where you are in the world, is key to moving forward,” said Patience Koku, a farmer from Nigeria part of the Global Farmer Network. “I don’t think the farmers in Africa or in Nigeria need a lot of convincing” to adopt innovation, Koku noted. If someone is able to explain what a new technology can do, “farmers see that science can make their life better and embrace it.”
Rising to the challenge
Agricultural research is also crucial to confront global threats like pests, conflict and climate change.

Two separate sessions, hosted by Corteva Agriscience and CIMMYT, shared the latest approaches in the fight against fall armyworm and other pests and diseases. The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, explained how organizations are working together to respond to the rapid spread of fall armyworm in Africa and Asia. “We have to solve the problem based on science, and then develop, validate and deploy integrated pest management approaches,” Kropff said.
As part of the World Food Prize outreach program, Bram Govaerts, director of innovative business strategies at CIMMYT, gave a lecture to students at Brody Middle School about the importance of agriculture and food. “When people can’t grow crops or pay for food to feed their families, desperation turns to conflict.”
At a side event, the Economist Intelligence Unit presented the Global Food Security Index 2018, which ranks food systems in 113 countries based on affordability, availability, and quality and safety. Senior consultant Robert Powell explained that the index now includes an adjustment factor based on each country’s natural resource risks and resilience to the impacts of a changing climate. “All countries will experience the impact of climate change,” Powell said.
The pernicious effects of climate change were also evident to the 2018 World Food Prize winners, David Nabarro and Lawrence Haddad, who have led global efforts to curb child malnutrition. “There is no evidence to me that [this] crisis is going to stop, because climate change is here,” Nabarro declared. “The foods we choose to grow and eat have a large impact on emissions,” Haddad said. “Food has a lot to offer” on climate mitigation and “diversity is the secret sauce” for climate adaptation. “We need food systems that are diverse: in crops, locations, organizations involved in them…”
Less biodiversity translates into “less resilience and worse nutrition,” according to the Vice President of Peru, Mercedes Aráoz. Through improved health and nutrition services, the country more than halved malnutrition among children under five, from 28 percent in 2008 to 13.1 percent in 2016.

A rallying cry for nutrition
The impact of nutrition on the first 1,000 days of life lasts a lifetime, explained Haddad. “For young kids, these are permanent shocks.”
“If a person is not nourished in those very important weeks and months of life, the long-term consequences are likely to be irreversible,” Nabarro added. According to him, nutrition needs to be the target in the 2030 agenda, not only hunger.
“Nutrition-based interventions present us a new lens through which to create and assess impact as agricultural researchers,” said Elwyn Grainger-Jones, the executive director of the CGIAR System Organization. “Our future success must come not only from ensuring an adequate supply of calories for the global population, but also the right quality and diversity of foods to tackle hidden hunger as well.”
“We are not going to resolve the challenges of undernutrition without the ag sector stepping up in a big way and differently,” argued Shawn Baker, director of nutrition at the Bill & Melinda Gates Foundation. “Nutrition needs you,” Baker told other participants. “Welcome to the nutrition family.”
DES MOINES (Iowa) — At the plenary of the 2018 Borlaug Dialogue, a global panel of experts gave an overview of the origins of the fall armyworm, how it is spreading around the world, and how governments, farmers and researchers are fighting against this pest.
Pedro Sanchez, research professor in tropical soils at the University of Florida and 2002 World Food Prize Laureate, shared background information on the history of the fall armyworm and the early attempts to neutralize it, decades ago. He pointed out that once-resistant varieties were eventually affected by this pest.
The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, shared the most recent developments and explained how organizations are working together to respond to this pest. “We want to have science-based, evidence-based solutions,” Kropff said. “We have to solve the problem based on science, and then to develop and validate and deploy integrated pest management technologies.”
The director general of the Ethiopian Institute of Agriculture, Mandefro Nigussie, reminded that in addition to affecting people and the environment, fall armyworm “is also affecting the future generation,” as children were pulled out of school to pick larvae.
The response against fall armyworm cannot be done by governments alone, panelists agreed. It requires the support of multiple actors: financing the research, producing research, promoting the results of the research and implementing appropriate measures.
Rob Bertram, chief scientist at USAID’s Bureau for Food Security predicted the fall armyworm will continue to be a “serious problem” as it moves and migrates.
The director general and CEO of the Kenya Agricultural & Livestock Research Organization, Eluid Kireger, emphasized the importance of global collaboration. “We need to borrow the technologies that are already working”.
The fall armyworm was also discussed during the Corteva Agriscience Forum side event, on a session on “Crop security for food security”. The Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize, B.M. Prasanna, was optimistic about the efforts to tackle this voracious pest. “I’m 100 percent confident that the pest will be overcome, but it requires very solid synergistic and coordinated actions at the national level, at the regional level and at the continental level.”
CIMMYT is co-leading the Fall Armyworm R4D International Consortium. “Fall armyworm is not going to be the only threat now and forever; there will be more insects, pests and pathogens moving around,” Prasanna said. “Global connectedness is exacerbating this kind of problem, but the solution lies also in global connectedness.”
Despite significant efforts to control the spread of the invasive Fall Armyworm, first detected in Africa in 2016, the pest keeps advancing to new areas in sub-Saharan Africa and beyond.
The effects of its insatiable appetite continue to be felt across the continent as it feeds on many crops in addition to maize, with for instance an increasingly growing appetite for sorghum and millet. Without appropriate action, the Fall Armyworm threatens to cause billions of dollars in annual damage to African food staples.
The international consortium members will hold their first face-to-face meeting on October 29-31, 2018, at the African Union Commission in Addis Ababa, Ethiopia.
Agricultural research for development has tremendous potential for widespread impact in poverty alleviation and food security. However, achieving real benefits for farmers is challenging and many well-intentioned projects fail to achieve large-scale impact. According to Brendan Brown, a postdoctoral research fellow with CIMMYT’s socioeconomics program in Nepal, this is where his work can help.
“There have been decades of work trying to improve agricultural livelihoods, but many of these interventions are yet to have tangible impacts for farmers,” Brown said. “My research seeks to help address this gap, using novel frameworks and applying participatory methods.”
Socioeconomic research at CIMMYT plays a key role at the nexus of agricultural innovations, helping to enhance interventions and initiatives for greater impact. Knowledge from such studies helps to prioritize and target resources, optimizing research capacity and accelerating the uptake of innovations.
“I attempt to understand constraints and opportunities at various scales from farms all the way up to institutional levels,” Brown explained. “I then seek to find pathways to catalyze change that lead to improved farmer livelihoods. Such research is integral to getting agronomic research into farmers’ fields.”
This area of research calls for a mixture of qualitative and quantitative tools and expertise, for which Brown is well suited. He has a bachelor’s degree in Agricultural Science with a major in Soil Science. “However, after working in agricultural research and development for a few years, I saw a gap in linking agronomy to the contextual realities of smallholder farming, so I opted to pursue a career that bridges the gap between the physical and social sciences.”
A desire to help
Brown grew up in Australia, between Sydney and a family farm on the south coast of New South Wales. He enjoyed being outdoors, “preferably barefoot,” participated in hobby farming, and from an early age showed an interest in social justice issues. A career aptitude test taken towards the end of high school revealed he was suited to be one of three things: a ship captain, a nurse or an agricultural scientist. He opted for the latter.
It was at university that Brown gained the insight of applying his agricultural knowledge to helping smallholder farmers. During a backpacking trip from Cape Town to Cairo, which incorporated some agricultural volunteering, he witnessed first-hand the difficulties farmers face in sub-Saharan Africa. Upon returning to his studies, he resolved to pursue a career that would enable him to help smallholders and, at the same time, address some of the world’s biggest ethical dilemmas.
Research with impact
Newly graduated, Brown worked with the Australian Centre for International Agricultural Research (ACIAR), based in Canberra, and the Food and Agriculture Organization of the United Nations (FAO), based in Ghana, where he gained hands-on experience working in agricultural systems in developing countries across Asia, Africa and the Middle East. It also inspired his PhD, which explored the disconnect between development work at research stations and the reality experienced by African farmers.
“During my PhD, I collaborated with CIMMYT through the Sustainable Intensification of Maize Legume Systems in Eastern and Southern Africa (SIMLESA) initiative. I developed a more nuanced approach to what ‘adoption’ actually means in terms of uptake and impact assessments. I also studied communities’ attitudes to conservation agriculture practices and diagnosed key institutional bottlenecks within research and extension systems.”
Brown’s studies allowed him to develop novel mixed methods and participatory impact pathways to promote new farming practices, such as conservation agriculture, to smallholder farmers in Africa. “My work with CIMMYT allows me to contribute to solving some of the world’s biggest issues. Through interacting with smallholders, facilitating conversations and creating new understanding, I hope to contribute to real change.”

Moving to Asia
After spending nearly a decade in and out of Africa, he joined the CIMMYT team in Nepal earlier this year and is relishing the opportunity to explore new contexts in South Asia.
“So much potential exists within the food systems of South Asia given the existence of multiple cropping seasons and diverse markets, as well as exciting developments in the use of mechanization and irrigation that have potential for delivering large-scale benefits, driving improved food security and profits.” However, he points out the integration of such innovations in this part of the world can be challenging due to inherent complex social hierarchies and caste systems. “I still have much to learn within such complex systems.”
Brown’s work in South Asia focusses on understanding the adoption, scaling and impact of sustainable intensification technologies and practices. He is primarily working with the Sustainable and Resilient Farming Systems Intensification (SRFSI) initiative, which aims to reduce poverty by making smallholder agriculture more productive, profitable and sustainable while safeguarding the environment and involving women in agriculture.
By studying the portfolio of CIMMYT-led initiatives in the region, he is also developing his understanding of prevailing sustainable intensification practices and the issues farmers face when implementing them. In addition to his work with SRFSI, Brown is soon to embark on a new ACIAR-funded research project aiming to enhance sustainable mechanization of farming systems in two provinces of Nepal by mobilizing strategic planning and collaboration.
“I look forward to sitting down with local agricultural service providers to understand how they run their businesses and how they structure their livelihoods,” Brown expressed. “This will then be paired with the perspectives of farmers, as well as extension officers, researchers and policymakers to build theories of change and pathways to maximize the uptake and impact of sustainable intensification practices.”
He highlights how local ownership of change can be fostered by implementing participatory methods during this process. This can result in transformative change, felt from the institutional level all the way to the smallholder farmer. Brown hopes his work in South Asia will deliver widespread impact for smallholder farmers and he welcomes collaboration and sharing of ideas and approaches with others working towards similar objectives.
This month’s report from the United Nations’ scientific panel on climate change highlights worsening food shortages as one of the key impacts of global warming.
Tackling the monumental challenges set out in the report may seem like a mountain to climb, given the policy changes and rapid government action required. Yet, on her 4-acre farm on the foothills of Mount Kenya in Embu county, 65-year-old Purity Gachanga proves it is possible to fight eroding soils, enrich farmland, and increase and diversify food production.
What’s more, she shares her methods with 60 women making up a “merry-go-round” group that meet regularly in her front garden. They each contribute a small sum of money which forms their communal savings system. “Many have put the money towards their farms but we also use it for other things we want like blankets, utensils or chairs,” explains Gachanga.
The group also helps the women share new methods, she adds. “I have learnt many techniques from scientists during training days and I am always one of the first to try these out on my farm. So when we get together for the merry-go-round meetings, I show the others what I am doing and how well it works. They then want to try on their own farms.”
Gachanga points to neat rows of fodder plants on the edges of her farm. “Before I would lose all this topsoil when it rained heavily. I learnt that planting certain varieties of fodder plants with deep roots holds the soil together. The plants also add fertility to the soil and give me good feed for my goats.”
Her goats are very precious as besides providing milk and meat, they helped her pay the school fees for nine of her children. The animals are an essential part of her sustainable farming system as they provide fertilizer for her fields.
The farm is flourishing with beans, kale, amaranth, tomatoes and pumpkins. Gachanga rotates the crops so the soil is never left exposed. “I get a profit from each patch so it makes sense to plan how to use it. I make money, keep my soil and animals in good health and we have a varied diet ourselves.”
The training she has received is part of an initiative called the Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA), whose goal is to scale up proven soil conservation and food production techniques. Its demonstration sessions bring researchers, extension agents, the private sector, and farmers together to discuss and share expertise, and Gachanga is a keen learner.
Richer soils, more food
Continual farming and mono-cropping of maize along with minimal fertilizer and manure use has rapidly depleted African soil nutrients and resulting yields. Farmers are also used to feeding their livestock with crop remnants from their fields which leaves the soils exposed, further worsening erosion and soil fertility. To address this, farmers are encouraged to leave either all or some crop residues on the field and add nitrogen-fixing legume crops in rotations with cereal crops and forages.
SIMLESA is on target to achieve its overall goal of reaching 650,000 farmers and increasing farm productivity in Eastern and Southern Africa by 30 percent by 2023.
Rahma Adam, gender specialist at the International Maize and Wheat Improvement Center (CIMMYT) which is leading SIMLESA, said rural women can access better opportunities by being part of a farming innovation group.
The Liganwa women farmers group in Siaya County in Kenya’s Nyanza Province, started in 2007 to help widows in the community get capital to start micro-businesses, and also uses the rotating ‘merry-go-round’ credit and savings system.
After initial challenges in raising capital, as some members were unable to pay their contribution, they joined SIMLESA as part of an agriculture innovation platform. “By experimenting with the demonstrated conservation agriculture techniques, the Liganwa women have since transformed their farming and incomes,” says Adams.
The platform has also enabled women as a group to negotiate better prices to buy inputs and sell produce. Better yields and markets mean members bring money to the group from the surplus maize they sell. So, the merry-go-round now turns with 3 to 5 times more borrowing capacity and 100 percent repayment rates.
One priority of the United Nations’ International Day of Rural Women on October 15 each year is to foster women’s empowerment through climate-resilient agriculture, as with Gachanga and the merry-go-round farmers groups. The challenge is making sure governments put policies and systems in place to ensure other farmers can, and want to, follow suit.

Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) is an eight-year food security program supported by the Australian Centre for International Agricultural Research (ACIAR).
Launched in 2010, SIMLESA is managed by the International Maize and Wheat Improvement Center (CIMMYT) and implemented by national agricultural research systems in Ethiopia, Kenya, Malawi, Mozambique and Tanzania. In Kenya, CIMMYT is working closely with the Kenya Agriculture and Livestock Research Organization (KALRO).
Over two billion people across the world suffer from hidden hunger, the consumption of a sufficient number of calories, but still lacking essential nutrients such as vitamin A, iron or zinc. This can lead to severe health damage, blindness, or even death, particularly among children under the age of five. Furthermore, a recent FAO report estimates the number of undernourished people worldwide at over 800 million, with severe food insecurity and undernourishment increasing in almost all sub-regions of Africa, as well as across South America.
In recognition of World Food Day and the focus of the 2018 World Food Prize on nutrition, the CGIAR Research Centers and Programs reflect on the significance and global impact of biofortification and climate resilient crops – key components in achieving Sustainable Development Goals 2: Zero Hunger and 3: Good Health and Wellbeing by 2030.
Biofortification enables scientists to fortify staple crops with micronutrients to address hidden hunger. There are now 290 new varieties of 12 biofortified crops – including maize, wheat and potatoes – being grown in 60 countries, reaching an estimated 10 million farming households.
The first biofortified maize variety was quality protein maize (QPM), developed by International Maize and Wheat Improvement Center (CIMMYT) scientists Evangelina Villegas and Surinder Vasal. QPM features enhanced levels of lysine and tryptophan, essential amino acids, which can help reduce malnutrition in children. Villegas and Vasal would later go on to win the World Food Prize in 2000 for this groundbreaking work, and genetic variation found in QPM would serve as the baseline for developing further biofortified products, such as zinc-enriched maize and vitamin A orange maize.

Several key factors have contributed to the success of biofortification. One is partnership. The CGIAR Centers work with hundreds of partners around the world, from national governments and research institutes through to non-governmental organizations and farmers on the ground. Other factors include the ability to build evidence and conduct thorough monitoring and evaluation, the maintenance of a clear vision on how research will have impact, and coordinated investment.
In considering the future role of biofortification in our evolving agricultural landscape, the article highlights the need to tie up with meeting global goals on sustainable development in terms of food security and improved nutrition, and the importance of ‘future proofing’ new varieties in the face of climate change.
In further support of biofortification, the UK’s Department for International Development (DFID) recognized the importance of CGIAR’s world-renowned agricultural research in the fight to end global hunger. Support from DFID has been crucial to biofortification work in Africa as well as in the development of drought-tolerant maize by CIMMYT and the CGIAR Research Program on Maize (MAIZE), which has increased farmers’ yields by up to 30 per cent, benefitting 20 million people in 13 African countries. Over 300 drought tolerant maize varieties were released by CIMMYT under the Drought Tolerant Maize for Africa (DTMA) project, which ran from 2006 to 2015, and continue to be scaled out and provide benefits to smallholder farmers in the region today. DFID also highlighted the impact of their support to CIMMYT and the CGIAR Research Program on Wheat (WHEAT) in the development of disease resistant wheat varieties that help avoid food shortages and exacerbated hunger worldwide.
After a prolonged decline in global hunger, findings pointing to a recent increase are alarming. Coupled with uncertainties surrounding food supply due to challenges like changing climates and ever-present crop pests and diseases, the challenges we face are significant. The development and deployment of crops biofortified with nourishing micronutrients and equipped to cope with abiotic and biotic stresses is of fundamental importance. The work of the CGIAR Centers and Research Programs is vital to improve the livelihoods of smallholder farmers and to fuel the fight towards zero hunger by 2030.

FOR IMMEDIATE RELEASE
MEXICO CITY — Breeders of spring wheat for North America and Russia need to adapt their varieties to the regions’ changing climates, which are bringing longer and wetter whegrowing seasons, according to a scientific paper published yesterday.
Published by a five-country team of wheat researchers, the study analyzed changes in wheat yields, along with air temperatures and precipitation, on farms and research stations in Canada, Kazakhstan, Russia, and the USA, from 1981 to 2015.
The 22 million hectare study area — nearly the size of the United Kingdom — accounts for as much as 10 percent of global wheat production and exports nearly all its wheat, making it a big contributor to world food markets, according to Alexey Morgounov, wheat scientist at the International Maize and Wheat Improvement Center(CIMMYT) and first author of the paper.
“June, when the grain-holding wheat spike begins to form, turned out to be the critical month for spring wheat,” Morgounov said. “Maximum temperatures for that month rose over the 35 years studied, which hurt yields, but average rainfall increased and boosted grain yield, offsetting the temperature effect.”
Still, breeding for adaptation to higher temperatures will be critical to increasing spring wheat yields, according to Morgounov, who added that there were substantial changes in the dates of planting and harvesting, normally leading to longer growing seasons in the regions studied. “New varieties should be able to take advantage of the longer wheat growing seasons that warming brings.”
Overall, climate changes were more favorable for spring wheat in North America than in Kazakhstan and Russia, with greater precipitation in Canada and the USA and less exposure to extreme, high temperatures. Growing season precipitation increased as much as 15 percent at North American locations.
The two regions covered in this study represent distinct environments. The Kazakhstan and Russia locations are more than 500 kilometers further north than the North American latitudes and experience colder winters, hotter summers, and less precipitation.
“Interestingly, the two regions appear to complement each other, over the period we studied,” Morgounov said. “Higher-than-average wheat yields in one were normally associated with lower yields in the other, helping to foster stability in grain markets.”
“The whole high-latitude, continental climate spring wheat area certainly presents a huge potential for global wheat production,” he added, “and both can benefit from germplasm exchange and cooperation, with emphasis on the climate change challenges and opportunities presented in this paper.”
Morgounov acknowledged contributions for the study from the Prairie Recommending Committee on Wheat, Rye and Triticale, Canada, and other Canadian partners; the USDA-ARS Plant Science Research Unit; the Samara Agricultural Research Institute, the Agricultural Research Institute of Southeast Saratov, the Altay Agricultural Research Institute at Barnaul, the Siberian Agricultural Research Institute at Omsk, the Shortandy Variety Testing Site, and the Siberian Crop Production Research Institute at Novosibirsk, Russia; and the Karabalyk Agricultural Research Station, Kostanay, Kazakhstan. Finally, Morgounov thanked the CGIAR Research Program on Wheat for its support.

DES MOINES (Iowa) — As winners of the 2018 World Food Prize, Lawrence Haddad and David Nabarro are being recognized today for their individual work in unifying global nutrition efforts and reducing child malnutrition during the first 1,000 days of life. With this award, food and agriculture leaders highlight the importance of linking food production and nutrition.
Haddad’s and Nabarro’s efforts were crucial in uniting food security policy and programs in the wake of the 2008 global food crisis, when wheat, maize and rice prices doubled. Haddad and Nabarro leapt into action, each rallying a broad group of food system stakeholders and development champions and pushing for the implementation of evidence-based policies.
Using economic and medical research, Haddad convinced leaders to make child and maternal nutrition a priority in the global food security agenda. Nabarro, a champion of public health at the United Nations, was directly responsible for uniting 54 countries and one Indian state under the Scaling Up Nutrition Movement.
The 2018 laureates’ work significantly improved nutrition for mothers and children in the critical first 1,000 days of life — the period from pregnancy to a child’s second birthday. Their relentless leadership and advocacy inspired efforts by countless others to reduce childhood malnutrition. Between 2012 and 2017, the world’s number of stunted children dropped by 10 million.
“I would like to personally congratulate Haddad and Nabarro for putting nutrition and healthy diets on the global agenda,” expressed Martin Kropff, the Director General of the International Maize and Wheat Improvement Center (CIMMYT). “Together, we have to strive to develop resilient agri-food systems that provide nutritious cereal-based diets.”
Food and agriculture leadership
The World Food Prize has been referred to as the “Nobel Prize for food and agriculture.” Awarded by the World Food Prize Foundation, it recognizes individuals who have advanced human development by improving the quality, quantity or availability of food in the world. Winners receive $250,000 in prize money.
The World Food Prize was founded in 1986 by Norman Borlaug, recipient of the 1970 Nobel Peace Prize.
Over the last two decades, a significant number of rural Bangladeshis – especially youth – have migrated to urban centers, looking for higher paying jobs and an escape from agricultural labor. Conor Riggs is the Global Director of Markets and Entrepreneurship at iDE. He says smallholder farmers in Southern Bangladesh are increasingly struggling to find and afford farm labor to help harvest crops and perform a variety of other on-farm activities.
Riggs says small-scale mechanization, such as two-wheeled tractors fitted with intensification machinery and surface irrigation pumps, can help farmers make up for this labor gap and increase productivity, while boosting the local economy by supporting micro- and small enterprises.
But as Riggs discussed at the recent Scale Up Conference at Purdue University, designing the perfect machine or technology is not enough to create sustainable, far-reaching impact. On the International Day for the Eradication of Poverty, we’re following up with him to learn more about the role of markets and partnerships in bringing small-scale mechanization to rural Bangladesh.
Q: Five years ago, CIMMYT and iDE co-designed and began implementing the USAID Cereal Systems Initiative for South Asia – Mechanization and Irrigation (CSISA-MI) project. What were the goals when you began?
Our goal was to establish a new industry for attachments in two-wheel tractors in agricultural mechanization, technologies like seeders, reapers and high-volume irrigation pumps for surface water. We wanted to help farmers access services through a fee-for-service model – small entrepreneurs buy machines and rent out those machines to farmers or directly provide that service themselves. There wasn’t really a market naturally growing for these machines in ways that included smallholders while being commercially viable, so we aimed to build it as best we could.
The results of this effort to date have been strong: 191,000 farmers can now access machinery services from a growing network of nearly 3,000 local microenterprise service providers, representing improved cultivation across 92,000 hectares in Southern Bangladesh. And we see abundant evidence that this market is scaling organically now that it’s established a model that works for both firms and farms.
Q: How did you create a market?
We incentivized several large conglomerates in the agri-business space to co-invest with us on several container-loads of these machines, which we imported from Thailand and China. We helped them find some early adopter dealers and local service providers who would actually buy them. Then we developed short-term smart subsidies to drive down the costs of supply chain development, accelerated customer adoption of the machines, and overall market growth.
An important aspect of our strategy is that we did not present these accelerating investments as typical subsidies; rather, we worked with our private partners to offer commercial discounts so that service providers and farmers would recognize the true value of the product and the short-term opportunity to adopt the technology in its initial commercialization phase.
We first implemented this strategy with two leading firms in the market who concurrently launched a very proactive marketing campaign. Then we started pulling back those discounts overtime, year by year, as the initial partner firms found the market opportunity, and redirected this acceleration process with an additional group of interested companies that also wanted to enter the market in an inclusive manner.
Q: So the companies were benefiting from the discount?
Yes, but we created a lot of conditions. Essentially, the more project investment that was committed by the project to discount the cost of the machinery, the more we expected to see both cash and in-kind investment from those companies. In the end, about a dozen companies come into the game with about five that have really driven a lot of heavy investment.
Partnerships have been key throughout this project. What were the different strengths iDE and CIMMYT brought to the table?
iDE is a market development organization. We focus on market-based solutions, technology commercialization, last mile distribution, and market access. Fundamentally, we see our job as de-risking the market for companies to invest in lower income areas and empower the farmer and their family as both consumers and suppliers in the formal economy. To do this, we employ a lot of supply chain development, product re-design and most importantly, we develop networks of micro-entrepreneurs to serve the ‘missing middle’ between the formal and informal economies.
CIMMYT brings leading capabilities in linking science and practice, with an un-paralleled strength in understanding the agronomic rationale and the agronomic and economic combinations of the technologies as they’re applied on the ground.
CIMMYT knew what technologies were needed on the ground in Southern Bangladesh to genuinely improve productivity and efficiency in the face of changing economic circumstances, and understood how to apply them to real world conditions in alignment with market-based diffusion mechanisms. CIMMYT was also instrumental in working closely with the Bangladesh Agriculture Research Institute (BARI) and extension services, key government partners that helped us ensure market development was in alignment with public and social policy.
It can be difficult finding a synergy between two different organizations. Did you run into any challenges?
CIMMYT and iDE have different specializations, and at the beginning, we had natural, friendly debates about how to best integrate them and achieve highly ambitious project objectives. But relatively quickly, we figured out how to learn from each other and synthesize our approaches for the best results. Both CIMMYT and iDE approached the partnership with a mission driven focus and a sense of constant, mutual respect for the value each partner brought to the table.
What do you see for the future?
As for iDE, we’re excited to expand this successful partnership with CIMMYT to figure out how we can further replicate this success in other countries where we both work. While some of the market conditions in Bangladesh have provided us with unique opportunities for technology scaling in mechanization, we’re highly optimistic that the underlying partnership principles and management systems of CSISA-MI can be replicated in other programs and country contexts – even in ostensibly more challenging market environments.
The theme for this year’s International Day for the Eradication of Poverty is: Coming together
with those furthest behind to build an inclusive world of universal respect for human rights and dignity.
Drought is the primary constraint on maize production in the quiet rural village of Songshuwa, in Yunnan province, China.
It serves as a reminder that people living in poverty often are disproportionately affected by human rights violations and global warming.
As climates shift and natural disasters become more common around the world, smallholder farmers and pastoralists face increasing threats to their livelihoods. The risk is particularly high in dryland regions where prolonged droughts or extreme heat can decimate crops and kill livestock. For those just barely hanging on, these shocks are enough to push them into the poverty trap. Uncertainty about what tomorrow brings further discourages farmers, rural financial services, value chain institutions and governments from investing in agriculture.
In a study released earlier this year, a group of researchers reviewed publications from the last decade to assess how agricultural production technologies and practices — for example, crop rotations — and institutional interventions — such as index-based insurance — can mitigate risk and improve farmer welfare. They found that improved crop varieties, conservation agriculture and diversified production systems can reduce adverse impacts of climate-related risk under some circumstances. Insurance and social protections can also create safety nets that enable farmers to manage risk and adopt improved technologies and practices.
The authors point out that there is limited evidence showing these interventions have helped a significant number of very poor farmers escape poverty. Further research is needed to understand what interventions, or combinations of interventions, can create impact at scale.
This work was implemented as part of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), which is carried out with support from CGIAR Fund Donors and through bilateral funding agreements. For details, please visit https://ccafs.cgiar.org/donors.

On World Food Day, October 16, the International Maize and Wheat Improvement Center (CIMMYT) joins the Food and Agriculture Organization of the United Nations and partners around the world in their call to realize Sustainable Development Goal 2: Zero Hunger by 2030. Learn how CIMMYT, HarvestPlus and Semilla Nueva are working together to use biofortified zinc-enriched maize to reduce malnutrition in Guatemala, an important component of Goal 2.
Over 46 percent of children under five in Guatemala suffer from chronic malnutrition. More than 40 percent of the country’s rural population is deficient in zinc, an essential micronutrient that plays a crucial role in pre-natal and post-natal development and is key to maintaining a healthy immune system. CIMMYT, HarvestPlus and Semilla Nueva are working together to change this, through the development and deployment of the world’s first biofortified zinc-enriched maize.
“In Latin America, Guatemala is among the top 3 countries with the highest rates of zinc and iron deficiencies, and it is characterized by a high production and consumption of staple foods such as maize and beans. This made Guatemala, along with Haiti, the top prioritized countries for biofortification in the region, according to the Biofortification Priority Index (BPI) for Latin America,” said Salomón Pérez, the HarvestPlus country coordinator for Guatemala. HarvestPlus developed the BPI in 2013 to select the countries, crops and micronutrients in which to focus their efforts in Latin America. The BPI combines three sub-indexes: production, consumption and micronutrient deficiency level. “As maize is a staple food in Guatemala, with high levels of consumption and production, the development of biofortified maize with enhanced zinc was prioritized for the country,” he said.
Biofortified maize is a unique and efficient way of improving nutrition. As the nutrients occur naturally in the plant, consumers do not have to make any behavioral changes to get results. Rather than having to import supplements or fortify food, seeds and crops are sourced within the country, which makes this option more sustainable and accessible even in remote rural areas. It tastes the same as non-biofortified maize varieties and requires no special preparation methods. This made biofortification the obvious choice for improving zinc deficiency in Guatemala, and CIMMYT the obvious partner.
“CIMMYT has over 50 years of experience in tropical maize breeding for different traits,” said Félix San Vicente, one of the CIMMYT maize breeders leading the project. “Throughout our history we have developed elite materials with important agronomic and nutritional traits, such as Quality Protein Maize (QPM).”
The long lineage of zinc maize
Developed by CIMMYT scientists Evangelina Villegas and Surinder Vasal, QPM has enhanced levels of lysine and tryptophan, essential amino acids, which can help reduce malnutrition in children. Villegas and Vasal would later go on to win the World Food Prize in 2000 for this groundbreaking work, and genetic variation found in QPM would serve as the baseline for developing zinc-enriched maize.

After years of breeding work and research, the world’s first biofortified zinc maize hybrid, ICTA HB-18, was released in Guatemala in May 2018. It was developed by CIMMYT, the CGIAR Research Programs on Maize (MAIZE) and Agriculture for Nutrition and Health (A4NH), and Guatemala’s Institute for Agricultural Science and Technology (ICTA) with support from HarvestPlus. Commercialized by Semilla Nueva under the name Fortaleza F3, the biofortified zinc maize hybrid contains 6-12ppm more zinc and 2.5 times more quality protein compared to conventional maize varieties. An open pollinated variety, ICTA B-15, was also released.
Just 100 grams of tortilla made of either of these varieties can provide 2.5 milligrams of zinc, 50 percent of the daily recommended intake for children, making zinc-enriched biofortified maize an excellent tool in the fight against malnutrition and hidden hunger.
As CIMMYT is a breeding organization, it depends on national partners to get seeds to the farmers. That is where Semilla Nueva comes in. This non-profit social enterprise is working to get high yielding biofortified seeds to farmers in Guatemala.

The last mile
“We need to be able to impact farmers with our improved germplasm,” said San Vicente. “Semilla Nueva takes us to the last mile, to the farmers, which alone we could not do, so that our breeding work can achieve impact in farmers’ fields and lives.”
Semilla Nueva targets commercial farmers in Guatemala, as they are the main source of maize consumed in the country. Typically, a quarter of their harvest is consumed at home and surplus is sold in local markets, meaning that the zinc maize not only provides increased income to farmers, but also improves nutrition in their families, communities and country at large.
“CIMMYT, along with partners like HarvestPlus, have provided the technologies and support to allow us to come up with new ways to improve farmers’ lives. Tapping into decades of research from qualified scientists is the only way that an organization of our size can have hope of making an impact in the lives of millions of farmers. That’s what makes the partnership so incredible,” said Curt Bowen, executive director and cofounder of Semilla Nueva. “We provide the innovative way to get technologies to farmers through our social enterprise model. CIMMYT and HarvestPlus come up with the technologies that we never could have come up with on our own. Together, we help thousands of families make huge changes in their lives and take on malnutrition, which is one of the world’s biggest challenges to ending global poverty.”
Semilla Nueva plans to produce 5,000 bags of Fortaleza F3 next year, which will represent 5 percent of the Guatemalan hybrid seed market.

“Farmers have responded very positively to Fortaleza F3. They are convinced of its performance, especially during the dry season,” said Angela Bastidas, senior operations director at Semilla Nueva. “The way we approach farmers is not different than other seed companies; through farm visits, meetings, or field days. We are not reinventing the wheel. The difference with us has been offering farmers exactly what they need in terms of maize performance and price. Additionally, they find that our maize produces soft tortillas that taste better!” she explained.
In the end, the results speak for themselves. Fortaleza F3 increases yields by 13 percent and profits by $164 per bag compared to other mid-priced seeds, which goes a long way in improving farming families’ livelihoods, food security and nutrition.
“With Fortaleza F3, I pay less for the seed compared to other mid-priced competitors that I used to plant. F3 also yields more, giving me a greater profit,” said Rómulo González, a farmer from the southern coast of Guatemala. “With the extra income I’ve gotten since switching to F3, I’ve been paying for my daughter to go to school. Fortaleza F3 not only gave me a good harvest, but also the ability to support my daughter’s education.”
Conserving organic matter in soils improves vital nutrients in wheat, according to new study in Ethiopia. On World Food Day, CIMMYT Systems Agronomist Frédéric Baudron highlights the role of healthy soils as a tool for fighting malnutrition, in an article published on The Conversation.
The study by Baudron and Stephen A. Wood of The Nature Conservancy found that wheat grown on soils rich in organic matter, especially near the forest, had more essential nutrients like zinc and protein. Ethiopia faces varying levels of hidden hunger: a deficiency in vitamins and minerals in food, despite rising yields.
In Ethiopia and many low and middle-income countries, Nitrogen-based fertilizers are out of reach for farmers. But low-cost techniques like agroforestry, minimum tillage, and planting nitrogen-fixing legumes can help African farmers enhance soils, and have been successfully implemented in different African farming systems. The study found that wheat farms near forests had richer soils due to decomposing trees and plants, and more livestock manure, pointing to the benefits of an integrated approach.
The researchers conclude that healthy soils are an important tool for “feeding the world well” and achieving Zero Hunger, one of the Sustainable Development Goals. “The finding offers a new solution in addressing growing malnutrition,” writes Baudron.
