As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.
Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

EL BATAN, Mexico (CIMMYT) — A new study shows that dietary diversity is highest in areas close to forests, even when people don’t collect forest food and don’t generate income from forest products.
Dietary diversity reflects the variety of foods you eat and is strongly associated with adequate nutrition you receive. Increasing dietary diversity is a key element in combatting malnutrition. In areas near forests, people typically have high-producing home gardens, fed by manure from the livestock they let graze in the woods.
Throughout the world, and particularly in the tropics, remaining forests are cut down to make way for farmland in order to feed a growing global population. However, even in areas of high food availability, children may struggle to get enough vitamins and minerals if they only eat calorically dense, nutrient sparse cereal crops, a phenomenon called hidden hunger. The authors state that while cereal crops will no doubt remain crucial to meet the caloric needs of the global population, it is important to maintain – and restore in places – high dietary diversity when facing hidden hunger. They recommend taking a holistic approach to agricultural development that maintains landscape diversity, as opposed to the current trend toward mono-cropping – growing a single crop year after year – and landscape simplification.

EL BATAN, Mexico (CIMMYT) – Education and partnership are essential to improve food security and ensure lasting world peace, two next generation hunger fighters interning at the International Maize and Wheat Improvement Center (CIMMYT) said in an interview for International Youth Day.
Research into agricultural innovation and cross-sectoral partnerships are the stepping-stones to overcome challenges that threaten our ability to produce enough nutritious food to meet growing global demand, said Jorge Del’Angel, an agricultural engineering student.
Del’Angel along with fellow intern Jonathan Poole are spending two-months at CIMMYT learning from some of the world’s top agricultural minds as part of the prestigious Borlaug-Ruan Internship program supported by the World Food Prize (WFP).
“I believe that education can fix a lot of global problems,” Del’Angel said. “We all understand that food security is a challenge but to understand that it’s a global problem we’ve got to build connections that allow people to learn and work together.”
With our ability to feed ourselves facing intensifying pressures from resource depletion, mounting inequality and the challenges of climate change, the internship program provides important training for a new generation of agricultural champions, said CIMMYT cropping systems agronomist Ravi Gopal Singh.
“Exposing youth to agriculture early is crucial to shaping their careers,” said Singh, who supervises Del’Angel at CIMMYT.
By taking an interest in agri-food systems, youth learn about challenges facing the world, and become ambassadors for spreading the word about how agriculture builds livelihoods and ensures peace, said Poole, who is shadowing nutrition experts at CIMMYT.
“No matter what age you are you can help tackle food insecurity,” he added.
Achieving a world free of hunger and eliminating poverty are essential conditions to pave the way for lasting world peace and are an essential part of the U.N. 2030 Agenda for Sustainable Development. The World Bank estimates economic growth from agriculture is up to four times more effective at reducing poverty as growth originating from other sectors.
The United States based internship program is unique in that it engages high school and college students in hands-on contemporary research at world-class institutions addressing food security issues at the a time when they are deciding their academic pursuits and careers, said Lisa Fleming, the Director of International Internships and Career Development at the WFP.

“We endeavor to involve youth participants in ways that allow them to approach food security with a feeling of personal responsibility, understanding and engagement in a fashion that does not bore, frighten or leave them feeling hopeless or fearful for their future,” Fleming said. She added that for interns hosted at CIMMYT in Mexico, “it is evermore inspiring for our young interns to have the opportunity to walk the halls and test fields in Dr. Borlaug’s footsteps.”
Norman Borlaug, 1970 Nobel Peace Prize laureate and original hunger fighter, dedicated his life to working against food insecurity as a lead researcher at CIMMYT and with groups around the world. The Borlaug-Ruan internship stems from his legacy and places youth in real-world science, agricultural and food security issues, helping to build an effective succession plan for identifying and developing new, innovative leaders to feed the world.
CIMMYT has hosted Borlaug-Ruan interns since the inception of the program in 1998, annually hosting numerous summer interns in Mexico with additional students mentored over the years in Turkey and Thailand.
EL BATAN, Mexico (CIMMYT) – Maize lethal necrosis (MLN) disease is putting maize production at risk in eastern Africa, escalating food insecurity in the region.
First reported in Kenya in 2011, it has subsequently spread rapidly to neighboring countries and has now been confirmed in six eastern African countries, including the Democratic Republic of Congo, Ethiopia, Rwanda, Tanzania and Uganda.
The disease, caused by a combination of the maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV), causes irreversible damage that kills maize plants before they can grow and yield grain. If a maize field is infected early in the cropping cycle, total yield losses may occur.
Scientist L.M. Suresh of the International Maize and Wheat Improvement Center (CIMMYT) plays a central role in efforts to keep the disease in check. He contributes significantly to the screening of maize germplasm against MLN/MCMV, and to the identification of maize hybrids with tolerance/resistance to the disease.
In 2013, CIMMYT and the Kenya Agricultural and Livestock Research Organization established an MLN screening facility in Naivasha, Kenya, northwest of the capital Nairobi. The center serves as a centralized platform for screening maize germplasm under artificial inoculation from CIMMYT as well as public and private sector partners.
Suresh joined CIMMYT in 2015 as maize pathologist for sub-Saharan Africa. He is also manager of the MLN screening facility. As almost all of the commercial maize varieties currently grown in eastern Africa are susceptible to MLN, it is crucial to identify and develop germplasm with tolerance/resistance to the disease.
His work involves identifying sources of resistance to MLN and its component viruses MCMV and SCMV, and he works closely with other scientists on the genetic basis of MLN resistance. In addition, he contributes to the identification of elite maize hybrids that offer tolerance/resistance to MLN.
The use of advanced phenotyping technology makes it possible to quickly make physical observations of the plants on a large scale without painstaking manual scoring.
Another major component of Suresh’s work focuses on epidemiological factors related to MLN disease transmission, particularly seed transmission of MLN-causing viruses.
While focusing on MLN, he also works on other foliar – or leaf – diseases that are a threat to maize. As manager of the MLN screening facility, Suresh is responsible for the screening and indexing of about 84,000 rows of maize trials each year in three to four planting cycles at the Naivasha facility.
As of 2016, nearly 100,000 germplasm entries have been screened against MLN. To date, nine first generation MLN-tolerant elite maize hybrids have been released in East Africa. Several second-generation, CIMMYT-derived, MLN-resistant hybrids are currently being tested under national performance trials in Kenya, Tanzania and Uganda.
Born in Madasuru-Lingadahalli, a rural village in southern India, Suresh grew up on a farm where he worked in the fields during school holidays helping with weeding, picking areca nuts and harvesting.
In the 1970s and 1980s, his father was recognized by the State Department of Agriculture as a “progressive farmer” for undertaking various innovative approaches to increase rice paddy yields. However, the family continued to face several challenges, including low yielding varieties, diseases, pests, water scarcity and volatile prices.
To try and overcome some of these hardships, Suresh decided to further his education in agriculture.
“I believe that a deeper knowledge of science might offer alternatives, and that we should explore these options to help smallholder farmers like my father get better yields without increasing costs,” Suresh said. “My family always supported me to pursue higher education in the field of agriculture.”
Before joining CIMMYT, Suresh worked for 19 years at seed companies, including 14 years for Monsanto in India, where he led a team of plant health scientists focusing on diseases in vegetables. Additionally, he supported teams working on maize and cotton to harmonize various disease screening protocols.
“Working in agriculture gives me the best opportunity to contribute to efforts to help smallholder farmers improve their livelihoods,” Suresh said. “CIMMYT is a place full of scientific rigor and experts who work collaboratively with partners and thus bring impact. A major disease like MLN brings researchers from various organizations and institutions from different parts of the world together to accelerate efforts to not only understand the disease and establish effective surveillance, but also to engage stakeholders to commercially scale up disease-resistant hybrids developed by CIMMYT.”
The MLN web information portal, to which Suresh contributes, provides comprehensive information on various initiatives to tackle the MLN challenge. This website and information management system was developed with the objective of providing a one-stop resource for all the relevant information on MLN to interested stakeholders.

The new maize lethal necrosis (MLN) online portal provides up-to-date information and surveillance tools to help researchers control and stop the spread of the deadly disease.
MLN was first reported in Kenya in 2011 and has since then been reported in several countries in eastern Africa, especially the Democratic Republic of the Congo, Ethiopia, Kenya, Rwanda, Tanzania and Uganda. The disease kills plants before they can grow, and the pathogens are transmitted by insects or contaminated seed. Serious damage to the region’s maize production from MLN has impacted household food security.
The online portal, found at mln.cimmyt.org, details the spread of MLN, where the disease has been managed and controlled, and how to identify it in the field. It also provides key MLN publications, surveillance software, MLN incidence maps, information on the MLN Screening Facility, and MLN-tolerant hybrids that are either released or in pipeline.
One tool on the portal is the MLN surveillance and monitoring system that provides real-time data to identify the presence and spread of the disease across five endemic countries in eastern Africa, and three selected non-endemic countries in southern Africa. The system was developed by scientists collaborating with the International Maize and Wheat Improvement Center (CIMMYT), with support from the United States Agency for International Development (USAID).
In 2016, MLN surveillance was successfully conducted in Malawi, Zambia and Zimbabwe – three major seed producing countries in Africa – and the data is presented in the portal, detailing MLN’s status across 652 surveyed maize fields. Future data gathered in other affected countries will also be uploaded to the portal as surveillance teams conduct fieldwork using Global Positioning System online survey tools, to assess the spread and severity of the disease in these countries. Ongoing surveillance in endemic countries allows stakeholders to see real-time updates on the spread of MLN.

Since the disease was first reported, collaborative efforts have resulted in the establishment of a MLN Screening Facility at the Kenya Agricultural & Livestock Research Organization (KALRO) center at Naivasha in 2013. The facility, managed by CIMMYT, has so far screened nearly 100,000 maize germplasm entries — 56 percent from CIMMYT — against MLN under artificial inoculation over the last four years.
Nine CIMMYT-derived MLN-tolerant hybrids have been already released in three countries – seven in Kenya, one in Uganda and one in Tanzania. Eleven second generation hybrids are currently in national performance trials in these countries. Intensive efforts are currently being made by seed companies in Kenya, Tanzania and Uganda to expand the delivery of MLN-tolerant maize seed to the smallholders.
The MLN portal enables researchers to comprehensively assess the situation with regard to MLN, helps strengthen the national disease monitoring and diagnostic systems by providing faster and accurate data, and offers access to CIMMYT-offered MLN phenotyping services.

NEW YORK (CIMMYT) – Food and agriculture have the potential to be major drivers in helping the international community achieve the U.N. Sustainable Development Goals (SDGs) by 2030, but are currently underutilized, said experts at a side event during the high-level political forum on sustainable development held this month in New York City.
Some 70 percent of the world’s poor live in rural areas where agriculture provides the main source of family income, directly impacting the food security, nutrition and livelihoods of millions, said delegates the Agriculture and Food Day to Implement the Sustainable Development Goals, hosted by the International Agri-Food Network on July 13.
Although agriculture is up to three times more effective than other sectors in boosting incomes of the world’s poorest, it only receives 4 percent of global aid, according to Michael Grant, deputy permanent representative of Canada to the U.N.
The session was organized to draw attention to the many challenges that still exist to prevent the realization of SDG2 “Zero Hunger” – which establishes a framework to end hunger, achieve food security, improve nutrition and promote sustainable agriculture – and consequently several other SDGs. Agriculture is deeply connected to all SDGs that aim to eradicate poverty and promote prosperity, a topic that was discussed by the high-level political forum on sustainable development July 10-19, as the international community took stock of achievements at the two-year mark.
“700 million people continue to live in extreme poverty,” said Peter Thomson, president of the U.N. General Assembly. “We must support global movements that work towards SDG2 so that come 2030, nobody is left behind in hunger or poverty,” he added.
“Despite advances, stunting in children has risen over 20 percent since 1990 in Africa,” said Yemi Akinbamijo, executive director of the Forum for Agricultural Research in Africa. Adding that malnutrition results in an 11 percent loss in GDP each year.
Additionally, the sector is the second largest emitter of global greenhouse gas emissions and the largest driver of deforestation, making agriculture one of the top contributors to climate change and biodiversity loss. At the same time, youth globally are turning away from agriculture, just as the world needs to set its sights on doubling food production over the next three decades.
“The United States needs to fill 60,000 agriculture-related jobs, but universities are only suppling about 60 percent of that demand,” said Jaine Chisholm Caunt, director general of the Grain and Feed trade Association.
How the development community addresses these challenges in our agri-food systems will have a significant impact on the success or failure of other SDGs, including those targeting resource management, ending poverty and malnutrition, building resilient infrastructure and empowering women and girls, argued the delegates.
David Nielson, co-chair of the Global Forum for Rural Advisory Services, cited former wheat breeder and Nobel Peace Prize laureate Norman Borlaug’s philosophy of knowledge sharing as a critical solution. Often the solution to agricultural development doesn’t lie in new technology, but can be as simple as sharing appropriate knowledge that works and is useful to farmers on their land, he said.
However, critical changes in the way farming communities access land and other resources – currently only 1 percent of women and 9 percent of men own land in Africa – must be made at the policy level so that these solutions can be successful in permanently bringing people out of poverty in the long-term, he added.
“When Kenya’s dairy industry became liberalized, my husband and I were able to build our own processing plant,” said Margaret Munene, co-founder and general manager of Palmhouse Dairies Limited Kenya, a dairy processing plant that has grown into a grassroots foundation of “Kenyans helping Kenyans.”
“The processing plant provided a market to farmers,” said Munene. “Before working there many women didn’t have bank accounts in their own names. We worked with microcredit organizations to improve their grazing units, buy better cows and other inputs. We also provided training to improve milk processing, to integrate dairy farming with other crops and other skills that improve income.”
Delegates at the conference also called for different sectors to work together and approach different aspects of the food security puzzle from a holistic perspective. Akinbamijo credited much of Africa’s food and nutrition challenges to the poor integration of science and production systems, with the latest research often failing to translate into the market.
“Governments and other public institutions must work better with the private sector,” added Rocco Renaldi, secretary general, International Food & Beverage Alliance. “Drawing on the expertise of non-state actors can help create novel solutions to agriculture’s challenges.”
“Farming communities can successfully develop without damaging the environment,” said Maria Beatriz Giraudo, a fifth-generation farmer from Argentina and advocate of no-till farming, an agricultural practice that retains soil moisture, builds up nutrients and improves biodiversity.
The International Maize and Wheat Improvement Center (CIMMYT) supports the SDG agenda to create a new global partnership based on solidarity, cooperation and mutual accountability to eradicate extreme poverty by 2030 and deliver on the promise of sustainable development. See how CIMMYT contributes to 10 of the 17 SDG goals in the Strategic Plan 2017-2022.

Islamabad (CIMMYT) — The United States Agency for International Development (USAID) and along with local and national media recently toured agricultural initiatives led by the International Maize and Wheat Improvement Center (CIMMYT) at the National Agricultural Research Centre (NARC).
Yusuf Zafar, Chairman of the Pakistan Agriculture Research Council (PARC), highlighted the Agricultural Innovation Program’s (AIP) aim to improve farming practices and livelihoods in farming communities – especially for smallholders – across Pakistan.
Funded by USAID and led by CIMMYT, AIP has helped boost agricultural productivity by bringing new technologies to the sector while of sustainable practices, which has helped improve Pakistan’s overall economy, Zafar added. Agriculture is the largest sector of Pakistan’s economy, supporting half of the country’s labor force.

Muhammad Imtiaz, CIMMYT country representative in Pakistan and AIP project leader, briefed media representatives about the collaboration between USAID and CIMMYT along with the NARC and other partners. He highlighted key AIP successes, such as such as the introduction of new planting machineries and drip irrigation systems.
The tour also visited to maize fields at NARC where AIP initiatives in improved livestock, maize and wheat were showcased. AIP scholars – students who have completed their master’s degree in the U.S. with AIP funds – were also present and provided information on their experiences and accomplishments.
AIP will continue to scale out successful technologies, encourage innovation through national agricultural research systems and secure resources to combat climate change effects in agriculture.
Like many scientists at the International Maize and Wheat Improvement Center (CIMMYT) who grew up in smallholder farm households, Dagne Wegary draws inspiration from recollections of adversity and has found in science a way to make things better.
“I saw how my community struggled with traditional crop and livestock husbandry and, at an early age, started to wonder if there was a science or technology that might ease those hurdles,” Wegary said, referring to his childhood in a village in Wollega, a western Ethiopian province bordering South Sudan.
“I chose to study and work in agriculture,” Wegary explains. “Even though the farming system in my home village has not changed significantly, I am happy that the community is now among Ethiopia’s top maize producers and users of improved seed and other agricultural inputs.”
As a maize seed system specialist, Wegary works at the nexus between breeding science and actual delivery of improved seed to farmers. He interacts regularly with diverse experts, including CIMMYT and Ethiopia’s breeders and members of the national ministries of agriculture, the Ethiopia Agricultural Transformation Agency (ATA), non-governmental organizations including Sasakawa Global-2000 and World Vision, and especially public, private or community-based seed producers.
Quality seed is farmers’ principal means to improve productivity and secure food, according to Wegary, who calls it “the carrier of complementary production technologies, which in combination with improved agronomy can significantly increase crop yields.”
“I am most happy with Ethiopia’s increased maize productivity and self-sufficiency, which is due partly to the use of improved technologies to which we all contribute,” he said, noting that maize grain yields in Ethiopia had more than doubled since the 1990s, reaching 3.7 tons per hectare in 2016, a level second only to that of South Africa, in sub-Saharan Africa.
According to Wegary, these improvements are the result of strong government support for maize research and development, along with the strong partnership between CIMMYT and the national program that has led to the release of high-yielding, stress tolerant and nutritionally-enriched maize varieties. He said that farmers’ have also increased their use of improved technologies and that public, private and community-based companies now market seed.
“Supplying seed used to be highly-centralized, but farmers’ main sources of seed now are cooperatives that buy from seed companies or companies that market directly to farmers” Wegary explained. “Many companies have their own stockists and dealers who directly interact with farmers.”
Before joining CIMMYT, as a scientist with the Ethiopian Institute of Agricultural Research (EIAR), Wegary helped to implement a number of CIMMYT-led projects. “These allowed me to know CIMMYT very well and sparked my interest in joining the Center and working with its high-caliber and exemplary scientists.”
A plant breeder by training with a doctoral degree in breeding from the University of the Free State, South Africa, soon after joining CIMMYT Wegary began to contribute to projects to develop and disseminate seed of improved maize varieties with high levels of drought tolerance and enhanced protein quality.
He has been involved since the early 2000s in promoting quality protein maize (QPM). The grain of QPM features enhanced levels of lysine and tryptophan, amino acids that are essential for humans and certain farm animals. Wegary took part in a CIMMYT project that supported the release of five new QPM varieties.
“Many companies are now producing and marketing QPM in Ethiopia,” Wegary said. A 2009 study in the science journal Food Policy found that eating QPM instead of conventional maize resulted in 12 and 9 percent increases in growth rates for weight and height, respectively, in infants and young children with mild-to-moderate undernutrition and where maize constituted the major staple food.
Wegary believes sub-Saharan Africa’s biggest challenges include climate change-induced heat and drought, natural resource depletion, and pest and disease outbreaks, coupled with increasing populations. In combination these factors are significantly reducing food security and the availability of resources.
“I want to be a key player in the battle towards the realization of food and nutritional security, as well as the economic well-being of poor farmers, through sustainable and more productive maize farming systems.”

EL BATAN, Mexico (CIMMYT) – Maize nutritionally enhanced with vitamin A can bring significant health benefits to deficient populations, but recent modeling studies in Zambia suggest that its impact is being cut short by the low retention of provitamin A carotenoids – a naturally occurring plant pigment also found in many orange foods that the body then converts into vitamin A – during storage and postharvest grain loss.
Up to 30 percent of grain is lost in African countries when maize is stored using common storage methods, such as artisanal silos or woven bags, due mostly to insect, rodent or fungi infestations and accumulation of poisonous chemical compounds called mycotoxins, which are produced by certain fungi.
A recent study evaluated the impact of carotenoid retention in orange maize using different storage methods to assess the most efficient way to store grain without losing vitamin A carotenoids. The researchers specifically evaluated how hammer and breakfast meal – the two most widely consumed grains in Zambia – age in metal silos, multilayer polyethylene and common woven bags, as well as single and multilayer polyethylene bags.
The researchers found significant differences between grain storage methods after 6 months of storage. Across all methods, hammer meal retained more carotenoid than breakfast meal after 4 months, though there was no difference in provitamin A carotenoid loss when using single and multilayer polyethylene bags.
Potential contribution of stored orange maize to the estimated average provitamin A requirement of children and women was around 25 percent – 26.5 and 24.3 percent for children and women, respectively – suggesting that orange maize meal can provide significant amounts of provitamin A to Zambian diets, even after 4 months of storage.

HARARE, Zimbabwe (CIMMYT) – More farmers in Zimbabwe are demanding high-yielding, highly nutritious and drought tolerant provitamin A maize.
In Zimbabwe, nearly one in every five children under the age of five years are vitamin A deficient. These deficiencies can lead to lower IQ, stunting and blindness in children, and increased susceptibility to disease across all ages. While vitamin A is available from a variety of sources, such as fruit, green leafy vegetables and animal products, these are often too expensive or unavailable to the more than 10 million people living in Zimbabwe’s rural areas.
Zimbabwe’s ZS242 – an orange provitamin A maize variety released on the market by the government in October 2015 – is particularly popular with farmers due to its nice aroma and good taste. Consuming foods made from orange maize, which is rich in beta-carotene, can provide maize-dependent populations with up to half their daily vitamin A needs, according to HarvestPlus.
Orange vitamin A maize has been conventionally bred to provide higher levels of provitamin A carotenoids, a naturally occurring plant pigment also found in many orange foods such as mangoes, carrots and pumpkins, that the body then converts into vitamin A.
These varieties are also high-yielding, disease resistant and drought tolerant, presenting an opportunity for farmers to not only increase yields but also enhance the availability of vitamins and minerals for people whose diets are dominated by micronutrient-poor staple food crops.
Mary Sikirwayi, a farmer from Murewa District, Zimbabwe, bought provitamin orange maize seed during a seed fair organized by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with the Technical Centre for Agricultural and Rural Cooperation.
The maize grew and matured so fast that by the time her family wanted to try the fresh cobs for cooking and roasting, they had already started to dry. After harvesting the grain, she decided to make sadza, a porridge-like staple food consumed in Zimbabwe. When her family ate the sadza, everyone was so excited about the good taste and flavor of the food.
In addition to the good taste of the sadza from the provitamin A maize, Sikirwayi said the yield from the orange maize is more than five times higher than the national maize average yield. In the coming year, she plans to double the planted area of orange maize, due to its high demand both on the market and in her household.
CIMMYT and HarvestPlus have been working with Zimbabwe’s Department of Research and Specialist Services, Ministry of Health and Child Care, universities, seed companies, processors, retailers and the Food and Agriculture Organization of the United Nations, to demonstrate the benefits of orange maize since 2012. The Zimbabwe government has expressed strong support for enriching the micronutrient content of plants and other crops, including maize.

HARARE, Zimbabwe (CIMMYT) – Delegates at a conference in June called for a new focus and increase in investment to ensure eastern and southern Africa’s farming systems can withstand the impacts of climate change.
Africa is likely to be the continent most vulnerable to climate change, according to the UN Framework Convention on Climate Change. Smallholders produce around 80 percent of all food in sub-Saharan Africa, and rely primarily on rainfall for irrigation – a source that is becoming scarcer and unpredictable under climate change. Farming is also often practiced in marginal areas like flood plains or hillsides, where increasing and more intense weather shocks cause severe damage to soil and crops.
Tanzania’s Minister for Agriculture, Food Security and Cooperatives Charles Tizeba said during a conference on the future of the Sustainable Intensification of Maize-Legume Based Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project, an initiative led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the Australian Centre for International Agricultural Research (ACIAR), that a paradigm shift in agricultural development is needed to enable smallholder farmers, especially those in rural areas, to produce enough to feed themselves and to sell.
Sustainable agricultural practices, improved seed varieties, use of fertilizers and better infrastructure are all technologies and practices that have been successfully tested by SIMLESA and have the potential to be expanded across the region, said Tizeba. He also called on governments in eastern and southern Africa to develop agricultural agendas based on farmer needs and opportunities SIMLESA identified through the project’s research efforts.
Over 100 people representing different governments, research institutions, development agencies and the private sector gathered in Tanzania to participate in the taking stock on sustainable intensification research for impact in eastern and southern Africa conference. Since 2010, SIMLESA has successfully tested locally-adapted sustainable farming systems throughout eastern and southern Africa. The project began its second phase in July 2014 and will focus on expanding climate-resilient technologies and practices throughout the region.

To date, a total of 268 and 378 maize and legume on-farm participatory variety selections were conducted by SIMLESA, where best performing maize and legume varieties that met farmer preferences were selected and scaled up by partner seed companies. The project has influenced over 235,000 farmers who adopted at least one sustainable intensification technology or practice.
CIMMYT Director General Martin Kropff called for the adoption of “climate-smart agriculture” that will make crops more resilient to continuing extreme weather events.
“For our farmers to be productive and ensure food security, we need to build resilience to climate change…we need to invest in new agricultural innovation now,” said Kropff.
Andrew Campbell, ACIAR chief executive officer, said climate change has already had a powerful negative effect on agriculture and food security for the world’s most vulnerable, and that these effects will become even worse in the future.
“It’s critical to integrate research into development initiatives,” said Campbell. “In this regard, SIMLESA’s work, in partnership with national agricultural research systems, becomes even more critical.”
At the project level, SIMLESA will aim to scale its sustainable intensification technologies to 650,000 farm households by 2023 in eight target countries through different partnership arrangements.
Many of the speakers at last week’s event said smallholder farmers must be part of discussions on climate change and food security as they are often among those most touched by the impacts of climate change, and they play an integral role in global agriculture systems.
To achieve the best results, SIMLESA will channel its experiences and lessons learned since its inception in 2010 and scale out its work through shared analysis, common research questions and learning through the monitoring, evaluation and learning portfolio, communications and knowledge sharing and a lean project management structure.
SIMLESA’s positive assessment of conservation agriculture-based sustainable intensification in the region suggests that policies that strengthen national and local institutions, build infrastructure for sustainable farming, improve financial investment in agriculture and increase access for innovative private investors, play a key role in alleviating poverty and food insecurity in the region.
The Sustainable Intensification of Maize-Legume Based Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project was launched in 2010. Funded by the Australian Centre for International Agricultural Research (ACIAR), SIMLESA aims to improve the livelihoods of smallholder farming communities in Africa through productive and sustainable maize–legume systems and risk management strategies that conserve natural resources. It is managed by CIMMYT and implemented by partners in Ethiopia, Kenya, Malawi, Mozambique and Tanzania.

MEXICO CITY (CIMMYT) – The International Maize and Wheat Improvement Center (CIMMYT) has grown 150 tons of renewed, improved maize seed that will be sent to Haitian farmers to help jump-start the country’s seed sector, improve local food security and decrease malnutrition. This will be the largest seed shipment to any country in CIMMYT’s history.
In 1998, CIMMYT, together with the Organization for the Rehabilitation of the Environment, introduced a new quality protein maize variety in Haiti. Named “Hugo” for CIMMYT maize breeder Hugo Córdova, the variety grew well under the island’s agro-ecological conditions and can decrease malnutrition and stunting among children that consume it. The product of decades of maize research in Haiti and Latin America, Hugo quickly became a favorite among farmers, but over time lost its genetic purity due to a lack of certified seed production and yields began to drop.
Now, CIMMYT is working to help Haiti build their seed sector from the ground up, from developing improved seed to replace old varieties to providing capacity development at every level of the maize seed value chain, with incredible results.
Haiti is the poorest country in Latin America and the Caribbean, with the lowest maize yields in the continent, and roughly 50 percent of the population is undernourished. These conditions have been exacerbated by a crippling earthquake in 2010, what is emerging as a longstanding drought, and devastating Hurricane Matthew in 2016 that affected 2 million people. According to the United States Agency for International Development (USAID), Haiti cannot achieve economic growth and national stability if food security is not addressed.
However, improving food security in Haiti is complicated by the fact that there are no formal seed companies, said Alberto Chassaigne, maize seed system specialist at CIMMYT.
“Farmers often sell their entire crop at harvest, leaving nothing for the next season, forcing them to plant simple maize grain that they buy from local markets rather than certified seed, drastically reducing yield over time,” said Chassaigne.
In 2015, CIMMYT launched the Mayi Plus initiative with the support of USAID-Haiti Feed the Future (FTF) to identify the most promising varieties for the future of maize farming in Haiti. The project would also work to produce a “renewed” Hugo to farmers in Haiti with greater genetic purity and yield, and provide capacity development to Haitians in the production and processing of seed of these improved varieties. This renewed Hugo, known as “Hugo Plus,” can produce up to seven tons per hectare, in comparison to traditional varieties currently planted in Haiti that produce on average less than one ton per hectare.
Through a systemic series of maize trials, scientists also found that new CIMMYT germplasm is already available that outperforms any other maize available in Haiti in both irrigated and rain-fed conditions. These resilient varieties, named “Mayi Plus I” and “Mayi Plus II” are currently under multiplication to be introduced to Haitian farmers as soon as possible.

Four tons of renewed Hugo were produced in 2015, 2.7 tons of which were produced in Haiti.
In the winter cropping season of 2016-2017, CIMMYT produced 150 tons of renewed Hugo seed in Mexico to send to Haiti, 50 percent more than the 100 tons they had planned to send. “This is the largest seed shipment ever sent by CIMMYT,” said Arturo Silva Hinojosa, leader of the International Maize Improvement Consortium in Latin America. “An additional 15 tons of seed will be harvested in Haiti, up from 0-3 tons in previous years.”
20 of the 150 tons of renewed “Hugo Plus” have already arrived in Haiti, where they will be sold to farmers at affordable prices in “agricultural input boutiques” established by FTF and partners. The remaining 130 tons will be used by CIMMYT and FTF to develop a strategic seed reserve in Haiti that will serve as a backup in case of natural disasters so that the country has immediate availability of seed stock for re-planting. The CIMMYT team in Haiti is currently working to find the best locations to store the strategic maize seed reserve.
To ensure that the genetic purity of renewed Hugo and other improved maize varieties will be maintained, CIMMYT is providing capacity development to help start Haiti’s seed sector from scratch. Project partners identified entrepreneurs interested in establishing a seed enterprise, and CIMMYT has been providing these entrepreneurs with in-depth training in seed processing and marketing, guidance on the infrastructure for a seed processing plant, and contacts throughout the world of equipment appropriate for Haitian conditions.
In addition, CIMMYT established a two-week course in seed production and seed processing with a FTF partner to train 13 Haitian technicians, who will now be able to train other Haitians interested in working in the country’s maize seed sector. A training manual is being prepared in French and Creole, and replication workshops will be conducted in target food security corridors of USAID in Haiti.
“This improved seed, and a self-sustaining seed sector capable of producing and marketing it, can contribute towards improved foreign exchange savings and will create local employment,” said Huntington Hobbs, former leader of strategic planning and research coordination for CIMMYT’s MasAgro project. “Increased maize production will bolster Haiti’s economy by providing feed for emerging industries in poultry and egg production, as well as the main staple of Haitian food security.”

CIMMYT researchers returned to Haiti in early June to advise seed companies on the installation of a seed processing plant, as well as to supervise trials and evaluations of new varieties and coordinate trainings in Haiti with trainers trained last February in Mexico.
In order to introduce local farmers to the new Hugo Plus maize variety and recognize CIMMYT’s contribution to Haiti’s food security through the Mayi Plus project, the USAID-Haiti Feed the Future Chanje Lavi Plante (CLP) project held a special event on June 21, 2016. The event was attended by farmers, agricultural input store managers and local partners, as well as staff from the Haitian Ministry of Agriculture and USAID who thanked CIMMYT for the recent 20 ton seed shipment.
“Hugo Plus is the result of many years of applied research work of CIMMYT in Haiti, and is a valuable alternative to the current varieties available in Haiti with such low yields,” said Micheal Wyzan, head of the office of economic growth and development at the Haiti mission of USAID. “We highly appreciate the fruitful collaboration between CIMMYT and the CLP project that allow farmers to increase their maize yields in the region.”
In his address to the audience, Alain Thermil, main liaison of Haiti’s Ministry of Agriculture with USAID, stated that, “CIMMYT is a very important organization in the world, and it is vital to Haiti that we establish and maintain a close relationship with CIMMYT.”
Jean Robert Estime, director of the CLP project in Haiti, agreed. “Through CIMMYT interventions, good quality seed is now available to farmers in Haiti. We are very grateful to CIMMYT, a great international organization with a mandate to do research on maize and wheat worldwide that is doing very important work in Haiti.”

ISLAMABAD (CIMMYT) – Farmers in Pakistan are eagerly adopting a nutrient-enhanced wheat variety offering improved food security, higher incomes, health benefits and a delicious taste.
Known as Zincol and released to farmers in 2016, the variety provides harvests as abundant as those for other widely grown wheat varieties, but its grain contains 20 percent more zinc, a critical micronutrient missing in the diets of many poor people in South Asia.
Due to these benefits and its delicious taste, Zincol was one of the top choices among farmers testing 12 new wheat varieties in 2016.
“I would eat twice as many chappatis of Zincol as of other wheat varieties,” said Munib Khan, a farmer in Gujar Khan, Rawalpindi District, Punjab Province, Pakistan, referring to its delicious flavor.
Khan has been growing Zincol since its release. In 2017, he planted a large portion of his wheat fields with the seed, as did members of the Gujar Khan Seed Producer Group to which he belongs.
The group is one of 21 seed producer associations established to grow quality seed of new wheat varieties with assistance from the country’s National Rural Support Program (NRSP) in remote areas of Pakistan. The support program is a key partner in the Pakistan Agricultural Innovation Program (AIP), led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the U.S. Agency for International Development (USAID).
“Over the 2016 and 2017 cropping seasons, 400 tons of seed of Zincol has been shared with farmers, seed companies and promotional partners,” said Imtiaz Muhammad, CIMMYT country representative in Pakistan and a wheat improvement specialist.
Zincol resulted from the CIMMYT’s “biofortification” breeding research, focused on enhancing nutrient levels in the grain of key food crops. Scientists develop biofortified crops using diverse genetic resources, including wheat landraces and wild relatives with the genetic potential to accumulate zinc in the grain.
Genes for enhanced grain zinc content from those sources are crossed into adapted, high-yielding varieties, over repeated cycles of selection involving many thousands of plants.
“One year after the release of Zincol, wheat farmers on more than 320 hectares are sowing the variety,” Imtiaz said.
He also noted that 15 tons of Zincol seed was shared free of charge for testing with 600 farm families in Sukkar District, Sindh Province, through an initiative of World Vision-Canada and HarvestPlus, a CGIAR research program dedicated to the study and delivery of biofortified foods.

Wheat: Vehicle for enhanced nutrition
Pakistan produces more than 25 million tons of wheat a year. The country has an annual per capita consumption averaging around 124 kilograms — among the highest in the world and providing over 60 percent of inhabitants’ daily caloric intake. The staple wheat-based foods are chappatis or a flat bread baked on the walls of large, cylindrical clay ovens.
Particularly in remote areas of Pakistan, human diets too often lack essential micronutrients such as zinc. According to a 2011 nutrition survey, 39 percent of children in Pakistan and 48 percent of pregnant women suffer from zinc deficiency, leading to child stunting rates of more than 40 percent and high infant mortality.
Zinc deficiency is also known to cause diarrheal disease, lower respiratory tract infections, malaria, hypogonadism, impaired immune function, skin disorders, cognitive dysfunction and anorexia, according to the World Health Organization.
“Given its role as a key food staple, wheat with enhanced levels of zinc and other micronutrients can contribute to better nutrition,” said Velu Govindan, a CIMMYT wheat breeder who specializes in biofortification and helped develop Zincol.
“Zincol also carries the genetic background of NARC 2011, a popular, high-yielding Pakistan wheat variety that resists wheat stem rust, a deadly disease that threatens wheat worldwide,” Govindan added.
As part of AIP and HarvestPlus, as well as with numerous public and private partners and farmer seed production groups in Pakistan, CIMMYT is leading the extensive evaluation, distribution and seed production of Zincol, said Krishna Dev Joshi, a former CIMMYT wheat improvement specialist who worked on the project.
“With modest resources and limited amounts of seed, we tested and promoted Zincol over the last two years in Balochistan, Punjab, and Sindh, covering 15 districts and engaging nearly 700 farmers,” Joshi explained.
Joshi said farmer seed producers and private seed companies were able to provide another 100 tons of seed in 2016, enough to sow more than 2,500 hectares in 2017 and over half a million hectares in 2018.
“Zincol reached farmers nine years after the initial breeding cross in 2007, several years more quickly than is the norm in Pakistan, partly because it was tested simultaneously in national and provincial trials,” Joshi added. “Zincol is part of a suite of new, micronutrient-enhanced wheat varieties bred by CIMMYT and partners for use in South Asia, a region whose inhabitants consume 100 million tons of wheat each year.”
For India, Govindan and partners created a new biofortified wheat variety using synthetic parents crossed onto WH1105, a CIMMYT-derived high-yielding variety grown in India’s Northwestern Plain Zone. The new variety out-yields other popular varieties by as much as 8 percent and has a 20 percent higher zinc content, as well as good resistance to yellow rust disease. Another new Indian variety, Zinc Shakti, has a 40 percent greater grain zinc content and is being marketed by the private sector and spread via farmer-to-farmer seed sharing.

Vitamin A deficiency is considered a major public health problem in Tanzania affecting over 30 percent of the population, mostly children in preschool and women of reproductive age. It can result in morbidity, loss of vision or blindness and even death.
Provitamin A maize (PVA) is a special type of biofortified maize that contains high levels of beta-carotene. Beta-Carotene is an organic, red-orange pigment abundant in plants and fruits and gives PVA maize an orange color. It is converted to vitamin A in the body after consumption to provide additional nutritional benefits.
Biofortification enhances the nutritional value of staple food crops by increasing the density of vitamins and minerals in a crop through either conventional plant breeding, agronomic practices or biotechnology. This can significantly reduce the prevalence of “hidden hunger” due to micronutrient deficiency.
Maize – a staple food in Tanzania – can serve as a cheap and sustainable source of vitamin A, especially for vulnerable populations. Stores of vitamin A in 5 to 7 year old children improved when they ate PVA maize, according to HarvestPlus research.
PVA maize was recently introduced in Tanzania through the Building Nutritious Food Baskets Project (BNFB), a joint effort by the Government of Tanzania, Tanzania Official Seed Certification Institute, the International Maize and Wheat Improvement Center and national seed companies. Two Provitamin A maize varieties – Meru VAH517 and Meru VAH519 – were released for commercial production by Meru Agro Tours and Consultants in September 2016.
To catalyze efforts to increase planting and consumption of PVA maize, different actors along the maize value chain launched a PVA maize platform for Tanzania. The platform will serve as an information and knowledge center on PVA maize in the country by linking different stakeholders to relevant authorities on matters relating to PVA maize, as well as provide capacity development opportunities for members on critical gaps relating to PVA maize knowledge and biofortification in general.
Membership of the platform is expected to become multi-sectoral and multi-disciplinary and include actors such as the ministry of health, school feeding programs and academic institutions. The platform will be led by national partners.
The International Potato Center is collaborating with a consortium of CGIAR research centers, the governments of Nigeria and Tanzania and national partners on BNFB, which is addressing hidden hunger by catalyzing sustainable investments for the production and utilization of biofortified crops. The project mainly targets rural populations, especially young children under the age of five and women of reproductive age, in Nigeria and Tanzania.
Breaking Ground is a regular series featuring staff at CIMMYT
EL BATAN, Mexico (CIMMYT) – In Pakistan, maize is the third most important cereal crop after wheat and rice and it is the first in productivity among all the cereals. However, Pakistan imports about 90 percent of the hybrid seeds used to produce the crop, costing the country as much as $60 million annually. Furthermore, the genetic diversity of the currently available maize varieties is not diverse enough to adapt to the varied agro ecologies of Pakistan.
“Pakistan can be considered as a new frontier for CIMMYT’s maize impacts,” Beshir said. “Except for some limited maize activities in the early 1980s, there were no coordinated research activities in the past 32 years. I am glad to revitalize and breathe new life into Pakistan’s maize sector.”
Almost half of children under age 5 are reportedly malnourished, Beshir said, adding that protein, vitamin A, and other micronutrient deficiencies in Pakistan are rampant, while the mortality rate is among the highest in South Asia.
Beshir’s work targets these underprivileged groups and in the foreseeable future, he hopes to see nutritional benefits improve significantly.
Throughout his life, Beshir has witnessed how small scale farmers are often unable to fulfill their basic needs as they struggle to get fair market prices for produce, in part due to middlemen and a lack of information in the market.
He grew up in Ethiopia, a country where agriculture is the mainstay of the economy, accounting for 80 percent of employment, according to UNDP. The livelihoods of Beshir’s grandparents and most of his relatives were dependent on agriculture, but his parents switched to a sideline business selling agricultural and food related products.
“I was brought up observing my parents’ entrepreneurial skills and efforts, but they wanted their children to pursue a career in science,” Beshir said, explaining how his parents encouraged him to attend university. “My father used to call me ‘doctor’ when I was a fourth grade pupil to inspire me in my education.”
Earning an undergraduate degree in agriculture and plant sciences was a life changing experience for Beshir, serving as an eye opener to the dire need for educated agricultural professionals to transform the livelihoods of rural farmers.
“Since then, I developed a passion on how to increase profits for rural farmers through technology promotion and targeted intervention.”
Beshir earned a Ph.D. in plant breeding from the University of the Free State, Bloemfontein, in South Africa, and was awarded a gold medal for his research project highlighting the severity of malnutrition in parts of sub-Saharan Africa and the ways quality protein maize seeks to address the issue.
Before joining CIMMYT in 2013, Beshir was the national partner in Ethiopia for a CIMMYT-led project on quality protein maize development and drought-tolerant maize for Africa.
“My involvement in these projects gave me a good grasp of how CIMMYT’s impact-oriented interventions practically change the life of farmers and brought a maize revolution in my country, in partnership with local institutions,” he said.
His current work in Pakistan mainly involves extensive testing of various maize products sourced from CIMMYT breeding hubs in Colombia, Mexico, Zimbabwe and the International Institute of Tropical Agriculture (IITA). Since 2014, more than 2,200 maize entries have been tested through the project.
Test samples consist of biofortified maize, as well as maize varieties that can tolerate major biotic and abiotic stresses, and they have been evaluated on more than 300 different sites in Pakistan. Such large scale testing is unprecedented in the history of maize in Pakistan.
Beshir’s led efforts resulted in the allocation of 49 market ready maize products (hybrids and OPVs) to partners in less than three years, a process that would otherwise have taken eight to 10 years to develop even a single product. The allocation of the new maize products has also given partners access to CIMMYT’s parental lines and breeder seeds, so that they can continue to lead sustainable seed businesses even after the project ends.
The facility will help national programs develop maize germplasm tolerant to maize stem borer attacks.
“As imported hybrid seeds are simply unaffordable to millions of small scale maize farmers, our research will enable local companies to provide affordable options to farmers,” he said.

El BATAN, Mexico, (CIMMYT) – To celebrate and expand the legacy of the late Evangelina Villegas Moreno, a pioneering Mexican cereal chemist who won the 2000 World Food Prize for co-developing quality protein maize, the International Maize and Wheat Improvement Center (CIMMYT) has named its maize quality laboratory in her honor.
A memorial plaque was unveiled on 6 June by Martin Kropff, CIMMYT’s director general, at the entrance of the CIMMYT lab that generates crucial grain quality data for the center’s global maize breeding efforts.
“What better way to honor Dr. Villegas’ accomplishments than to have a CIMMYT maize quality lab named after her?” Kropff said. “The center is proud to have counted among its ranks a professional like Dr. Villegas, a pioneering Mexican scientist whose contributions to nutrition and food security will continue to resonate in impoverished regions.”
Breeding lines and populations from CIMMYT’s maize program are used in 100 countries and result in high-yielding, resilient varieties and hybrids grown on at least 20 million hectares throughout the tropics and subtropics.
One derivative of that work, known as quality protein maize (QPM), was developed by Villegas and Surinder K. Vasal, another former CIMMYT maize breeder and distinguished scientist, with whom she shared the 2000 World Food Prize.
Maize grain is rich in carbohydrates but poor in protein. In particular, it is lacking in the amino acids lysine and tryptophan, which are key protein building blocks in human diets. QPM grain contains more of those amino acids and so offers better nutrition for people with heavily maize-based diets, as is the case in parts of Latin America and sub-Saharan Africa.
A 2009 study in the science journal Food Policy found that eating QPM instead of conventional maize resulted in respective 12 and 9 percent increases in growth rates for weight and height, in infants and young children with mild-to-moderate undernutrition and where maize constituted the major staple food.
“Today, almost 30 years after Villegas retired from CIMMYT, the chemical and analytical approaches she developed still underpin work to monitor protein quality in QPM,” said Natalia Palacios, CIMMYT maize nutrition quality specialist and current head of the renamed lab. Together with Kropff, Vasal and Villegas’ sister, Juana Villegas Moreno, Palacios helped unveil the new plaque in a ceremony attended by 100 current and former CIMMYT personnel and Villegas’ family members.
Groundbreaker in science and society
Known as “Eva” to colleagues, Villegas, who passed away in April 2017, was born in Mexico City in 1924 and earned a Bachelor of Science degree in chemistry and biology at Mexico’s National Polytechnic Institute, at a time when higher education for women was still a novelty.
In 1950, she began her career as a chemist and researcher at Mexico’s National Institute of Nutrition and at the Office of Special Studies, an initiative funded by the Rockefeller Foundation and the Mexican government that was CIMMYT’s precursor.
She returned to CIMMYT in 1967, after earning a Master of Science degree in cereal technology from Kansas State University and a doctoral degree in cereal chemistry and breeding from North Dakota State University.
Villegas worked with Vasal in CIMMYT’s QPM breeding program, which operated from 1970 to 1985. Requiring the capacity to select for intricate gene combinations before the advent of DNA markers or genetic engineering, the program could not have succeeded without the support of Villegas’ lab and science, according to Vasal.
“I would call it exemplary interdisciplinary work (for) a breeder and a biochemist,” said Vasal. “Her lab analyzed 26,000 grain samples or more a year and provided the data in time for us to sow or pollinate experimental lines. Eva also furnished valuable critical suggestions that improved our breeding work.”
In a message read at the unveiling, Sanjaya Rajaram, 2014 World Food Prize recipient and former CIMMYT wheat scientist and program director, recalled Villegas’s significant contributions to the center’s wheat breeding research, which included establishing the center’s wheat industrial quality lab.
An inspiration in science to improve nutrition
Villegas’ prizes and professional recognitions include the 2000 Woman of the Year award of the Mexican Women’s Association, presented to her by former Mexican President Ernesto Zedillo. In 2001 Villegas was named to Alpha Delta Kappa’s prestigious list of International Women of Distinction and received the Lazaro Cardenas Medal from the National Polytechnic Institute. In 2013 Kansas State University (KSU) honored Villegas with an Outstanding Alumni Award.
“As a scientist, as a woman and as a Mexican, Villegas will continue to inspire future generations working to enhance food security and nutrition for the disadvantaged,” said Palacios.
