TEXCOCO, Mexico (CIMMYT) — More nutritious crop varieties developed and spread through a unique global science partnership are offering enhanced nutrition for hundreds of millions of people whose diets depend heavily on staple crops such as maize and wheat, according to a new study in the science journal Cereal Foods World.

From work begun in the late 1990s and supported by numerous national research organizations and scaling partners, more than 60 maize and wheat varieties whose grain features enhanced levels of zinc or provitamin A have been released to farmers and consumers in 19 countries of Africa, Asia, and Latin America over the last 7 years. All were developed using conventional cross-breeding.

Farmer and consumer interest has grown for some 60 maize and wheat varieties whose grain features enhanced levels of the essential micronutrients zinc and provitamin A, developed and promoted through collaborations of CIMMYT, HarvestPlus, and partners in 19 countries (Map: Sam Storr/CIMMYT).

“The varieties are spreading among smallholder farmers and households in areas where diets often lack these essential micronutrients, because people cannot afford diverse foods and depend heavily on dishes made from staple crops,” said Natalia Palacios, maize nutrition quality specialist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the study.

More than 2 billion people worldwide suffer from “hidden hunger,” wherein they fail to obtain enough of such micronutrients from the foods they eat and suffer serious ailments including poor vision, vomiting, and diarrhea, especially in children, according to Wolfgang Pfeiffer, co-author of the study and head of research, development, delivery, and commercialization of biofortified crops at the CGIAR program known as “HarvestPlus.”

“Biofortification — the development of micronutrient-dense staple crops using traditional breeding and modern biotechnology — is a promising approach to improve nutrition, as part of an integrated, food systems strategy,” said Pfeiffer, noting that HarvestPlus, CIMMYT, and the International Institute of Tropical Agriculture (IITA) are catalyzing the creation and global spread biofortified maize and wheat.

“Eating provitamin A maize has been shown to be as effective as taking Vitamin A supplements,” he explained, “and a 2018 study in India found that using zinc-biofortified wheat to prepare traditional foods can significantly improve children’s health.”

Six biofortified wheat varieties released in India and Pakistan feature grain with 6–12 parts per million more zinc than is found traditional wheat, as well as drought tolerance and resistance to locally important wheat diseases, said Velu Govindan, a breeder who leads CIMMYT’s work on biofortified wheat and co-authored the study.

“Through dozens of public–private partnerships and farmer participatory trials, we’re testing and promoting high-zinc wheat varieties in Afghanistan, Ethiopia, Nepal, Rwanda, and Zimbabwe,” Govindan said. “CIMMYT is also seeking funding to make high-zinc grain a core trait in all its breeding lines.”

Pfeiffer said that partners in this effort are promoting the full integration of biofortified maize and wheat varieties into research, policy, and food value chains. “Communications and raising awareness about biofortified crops are key to our work.”

Emergency seed fuels quick farm recovery in drought-affected Ethiopia

In response to Ethiopia’s worst drought in 50 years and the country’s critical shortage of maize and wheat seed for sowing in 2016, Ethiopian organizations, seed producers, and the International Maize and Wheat Improvement Center (CIMMYT) partnered to deliver over 3,400 tons of high quality seed to farmers, which was sown on more than 100,300 hectares.

“This effort helped rescue the food security and livelihoods of more than 271,000 rural households and 1.6 million individuals in Ethiopia’s Amhara, Oromia, Tigray, and SNNP regions, and strengthened seed systems to address future climate, disease, and pest crises,” said Bekele Abeyo, CIMMYT wheat scientist who led the seed relief initiative.

Funded by the U.S. Agency for International Development (USAID) and Office of Foreign Disaster Assistance (OFDA) of the U.S. Ethiopia mission, seed relief complemented international and national food aid, helping farm families to quickly grow crops after several seasons of erratic or failed rains in Ethiopia and the catastrophic 2015-16 El Niño droughts. At that time, more than 10 million people struggled to find food, as eastern Ethiopia faced crop losses from 50 to 90 percent of expected yields.

“We went three years without rain,” says farmer Usman Kadir, whose 1.5-hectare homestead in Wanjo Bebele village, Halaba Special Woreda, supports a household of 11 persons. “We were able to eat thanks to emergency food programs.” In 2017, Kadir used emergency maize seed to sow half a hectare and harvested 3 tons, getting his farm back on its feet. “If more new improved varieties come, we want to work with you and expand our farming operation.”

Wheat and maize: Mainstays of food security

Agriculture provides 42 percent of Ethiopia’s GDP, 77 percent of employment, and 84 percent of exports. Subsistence, smallholder farmers predominate, making their living from less than two hectares of land. Wheat and maize are the most important crops for food security; they are also at the center of Ethiopia’s increasingly vibrant agricultural output markets and have been the focus in recent years of public investment to raise national production.

Maize and wheat production in Ethiopia depends on rainfall, making the unpredictable weather patterns caused by climate change exceptionally detrimental here. Various studies predict an average 30 percent reduction in farm incomes due to climate change impacts, including greater extremes in temperatures and rainfall (floods, droughts) and the emergence of new pest and disease strains. Research shows that reduced precipitation is already holding back wheat yields.

To address this, experts identified maize and wheat varieties suitable for drought-affected areas and highly resistant to prevalent crop diseases. Of the maize varieties, some 10 percent were quality protein maize, which carries enhanced levels of key amino acids for protein synthesis in humans.

“This effort also provided training for district and zonal development agents in crop protection, agronomy, drought mitigation practices, and seed systems,” said Abeyo. “Finally, five women seed producer associations received wheat seed threshers and a large union of farmer seed producer cooperatives received a maize sheller through the initiative. This equipment will greatly expedite their operations and contribute to the expanded and more reliable access of farmers to affordable, quality seed in the future.”

Partners and contributors

Emergency relief seed was sourced through diverse CIMMYT partnerships, including producers in the USAID-funded “Drought Tolerant Maize for Seed Scaling Project” (DTMASS) and “Wheat Seed Scaling Initiative.” Stakeholders included the Ministry of Agriculture and Natural Resources (MoANR), the Bureau of Agriculture and Natural Resources (BoANR), public and private seed companies/enterprises, farmer cooperative unions, federal and regional research institutes, and non-government organizations working in target areas. With funding from the Bill & Melinda Gates FoundationEthiopia’s Agricultural Transformation Agency (ATA) helped deliver seed to drought-affected districts and jointly organized training and workshops.

Strengthening Results-based Management in the MAIZE and WHEAT CRPs

By Michelle Guertin/CIMMYT

EL BATAN, Mexico (September 18, 2015)- Recognizing the importance of managing for results and learning from experience, the MAIZE and WHEAT CGIAR Research Programs (CRPs) have been taking steps to strengthen results-based management (RBM) within the CRPs. In the last several months, both CRPs held multiple participatory workshops (see details below) to develop theories of change (ToCs) for their diverse research areas. These ToCs map out how and why a given research area will lead to specific results. ToCs are often used as a framework for testing hypotheses, where evidence is collected to validate the pathway of change.

The participatory nature of these workshops allowed the research teams to come together and develop consensus-based and aligned theories of change. This process was important to build buy-in and ownership. It was also recognized that change maps can support the development of research strategies and contribute to strengthening proposal development and results reporting by ensuring alignment and consistency across projects and programs.

Alignment is important not only at the project and program levels. Theories of change were clearly linked to attaining higher and global level results from the new CGIAR Strategy and Results Framework 2016-2030 and the upcoming Sustainable Development Goals. It was important for both CRPs to demonstrate how their programs contribute to global issues of poverty reduction, food security, improved nutrition, promotion of sustainable agriculture, and the achievement of gender equality.
