Better together: Partnership around zinc maize improves nutrition in Guatemala

Written by Jennifer Johnson on October 16, 2018. Posted in Features.

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.”

Fighting hidden hunger from the ground up: the powerful link between soils and nutritious food

Written by on October 15, 2018. Posted in News.

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.

CIMMYT has key role to address global nutrition challenges, says maize quality specialist

Written by Emma Orchardson on October 15, 2018. Posted in News.

Exposure to more frequent and intense climate extremes is threatening to reverse progress towards ending hunger and malnutrition. New evidence points to rising world hunger. A recent FAO report estimated the number of undernourished people worldwide at over 800 million. Severe food insecurity and undernourishment are increasing in almost all sub-regions of Africa, as well as across South America.

“It’s very important to ensure food security,” says CIMMYT maize quality specialist Natalia Palacios. “But we also have to focus on food nutrition, because increasing yields doesn’t always mean that we’re improving food quality.” Food quality, she explained, is affected not only by genetics, but also by crop and postharvest management practices. As head of CIMMYT’s maize nutritional quality laboratory, Palacios’ work combines research on all three.

As she prepares to attend the World Food Prize in Des Moines, Iowa – which this year recognizes the contributions of those working to combat malnutrition and ensure food and nutrition security – Palacios discusses ways in which she and CIMMYT colleagues work to address health and nutrition challenges.

What role can CIMMYT play in addressing global nutrition challenges?

Nutrition is an interdisciplinary issue, so there are several ways for CIMMYT to engage. In breeding, there’s a lot we can do in biofortification—which means to increase grain nutrient content. The CIMMYT germplasm bank, with its more than 175,000 unique collections of maize and wheat seed, is an invaluable source of genetic traits to develop new nutritious and competitive crops.

CIMMYT also addresses household nutrition challenges, including food availability, proper storage, and consumer behavior and choice. In cropping systems, the Center studies and promotes diversification, agroforestry, and improved soil health and farming practices, and at the landscape level it examines the role of agricultural practices. Gender research and foresight allow us to identify our role in the evolving setting of agri-food systems and rural transformation. We are prioritizing areas where CIMMYT can play a key role to address global nutrition challenges and partner effectively with leading nutrition groups worldwide.

How does the biofortification of staple crops like maize and wheat help to improve nutrition?

CIMMYT biofortification research has focused on micronutrients such as provitamin A in maize and zinc in both maize and wheat, to benefit consumers whose diets depend on those crops and may lack diversity. Biofortification must be complemented by enhanced dietary diversification and education for better nutrition.

How important are processing and post-harvest storage in terms of ensuring high-nutritional quality?

Research on post-harvest processing and storage is key to our work. A critical topic in maize is monitoring, understanding, and controlling aflatoxins—poisonous toxins produced by molds on the grain. CIMMYT has worked mainly to develop aflatoxin-tolerant maize, but recent funding from the Mexican food industry has enabled us to launch a small, more broadly-focused study.

In the past, aflatoxins showed up every three or four years in Mexico, and even then at fairly low levels. Aflatoxin incidence has lately become more frequent, appearing almost every year or two, as climate changes expose crops to higher temperatures and fungi are more likely to develop in the field or storage, especially when storage conditions are poor.

What are the implications of high aflatoxin incidence for health and nutrition?

The implications for health and nutrition are huge. High consumption can affect the immune system and lead to pancreatic and liver cancers, among other grave illnesses.

How easy is it to tell if a kernel is contaminated?

It’s impossible to tell whether grain is contaminated without doing tests. The chemical structure of the toxin includes a lactone ring that fluoresces under UV-light, but this method only tells you whether or not the toxin is present, and results depend contamination levels and kernel placement under the lamp.

We’re spreading the lamp method among farmers so they can detect contamination in their crops, as well as making other of our other methods more accessible and less expensive, for use by farmers and food processors.

New publications: Exploring the gendered rules shaping agricultural innovation

Written by Emma Orchardson on October 12, 2018. Posted in Publications.

How do gender norms, agency and agricultural innovation interlink? How can we research this question comparatively to better understand patterns without overlooking the specificities of different contexts and the people who occupy them? These questions set the stage for the new special issue in the Journal of Gender, Agriculture and Food Security (Agri-Gender) on the GENNOVATE research initiative.

Ahead of the International Day of Rural Women (October 15), researchers from across CGIAR drew on the voices of over 7,000 rural women and men across diverse regional contexts to demonstrate why understanding and addressing gender norms is critical for achieving sustainable and equitable development.

Gender norms comprise the social rules that differentiate what a society considers a man and a woman should be in their lives. The papers published in the GENNOVATE special issue provide new empirical and methodological contributions to the literature on gender, agricultural innovation and rural transformation. The testimonies gathered across 137 communities in 26 countries illuminate how agricultural innovation processes are regularly constrained by gender norms. These norms prescribe women’s deference to men’s authority and in turn assign women with heavy household and care work burdens. They also limit their access to resources, physical mobility and social interactions.

Challenging the norms

Nevertheless, women and men find ways to challenge and redefine these norms, and village practices are often different from normative expectations. In a large majority of GENNOVATE research communities, women influence important household decisions and innovate in their rural livelihood activities, albeit often close to their homesteads and on a smaller scale than rural men. Some gender norms are beginning to relax to accommodate women’s and men’s changing lives, but these processes vary greatly across the types of norms, the groups of people concerned — young or unmarried women, widows, resource-constrained women, etc. — and the places where they live. By and large, women continue to face a myriad of barriers trying to expand their economic initiatives.

Two of the papers in the special issue explore gender norms in circumstances where farmer innovation and community development are particularly prevalent. CIMMYT researcher Lone Badstue and co-authors present findings from 336 semi-structured interviews with rural women and men from 19 countries who are known in their villages for agricultural innovation. While finance and physical assets emerge as important enablers of innovation, the testimonies stress that factors related to personality and agency are key drivers for both women’s and men’s capacity to innovate. Compared to men, women innovators are far more likely to detail how supportive spouses, parents, siblings, in-laws or children can help them learn about and adopt new farming techniques or otherwise actively innovate in their rural livelihoods.

In another paper focused on 79 community case studies, Patti Petesch and co-authors focus on a small set of “transforming” villages, where participants in the GENNOVATE study widely reported accelerated processes of empowerment and poverty reduction in their communities. Case studies and comparative evidence are able to show that more equitable gender norms play a crucial role in catalyzing inclusive agricultural innovation and development processes.

Other papers in the issue emphasize concerns over innovation processes that reinforce gender inequality and marginalize specific social groups. For example, Marlène Elias and co-authors focus on rural youth in seven countries to demonstrate how norms that discriminate against women in agriculture are key for understanding young women’s limited aspirations in agricultural work. Petesch and co-authors also introduce the concept of local normative climate to shed light on the contextual and fluid ways in which norms operate, such as why in one community only men perceive their village to be an enabling climate for their agency and agricultural innovation, while in another community only women perceive this.

A large-scale endeavor

Two papers describe GENNOVATE’s methodology and conceptual framework. The authors reflect on the challenges and opportunities faced in carrying out the large-scale qualitative study. They highlight the need to be attentive to the complexities of various local social contexts and women’s and men’s own understanding of their lives, while looking for patterns to make broader claims that can contribute to agricultural research and development. They also discuss GENNOVATE’s research protocols for sampling, data collection and analysis, and reflect on challenges that correspond with their application.

The GENNOVATE papers make evident that gender norms set the stage for agricultural innovation and that some people and places find pathways to forge ahead far faster than others. The special issue makes an important contribution to the development of strategies that are meaningfully informed by social realities while also allowing for comparisons across various contexts. This insight is relevant to research and development beyond the field of agriculture and natural resource management.

The GENNOVATE special issue in the Journal of Gender, Agriculture and Food Security (Agri-Gender) was published on September 2018, Volume 3, Issue 1.

The GENNOVATE research initiative is a collaboration of 11 CGIAR research programs.

The feminizing face of wheat farming in South Asia

Written by Courtney Brantley on October 12, 2018. Posted in Features.

In wheat systems throughout South Asia, the gender myth that “wheat is a man’s crop” is still pervasive. To debunk this myth, the International Maize and Wheat Improvement Center (CIMMYT) is combatting stereotypical norms of women in agriculture through GENNOVATE, a project carried out by 11 CGIAR Research Programs. Led by CIMMYT, this global comparative research initiative strives to address the questions of how gender norms influence men, women and youth to adopt innovative practices and technologies in agriculture and natural resource management.

Surprisingly, there was little knowledge and little literature on the intersection of wheat farming and gender before 2013. What was peculiar about the narrative of women wheat farmers in South Asia was that they were described — by rural advisory services, research organizations and even farmers themselves — as if they had never set foot in a field. On the ground, however, the local reality has long been different. Women, typically from particular castes and income groups, are involved in field operations.

South Asia is experiencing a rise in innovative undertakings by women in agriculture. This change, fueled by strong male outmigration in some locations, has been promoted by equality narratives created through social and women’s movements, NGOs and education. They have all contributed to strengthen women’s desire to have a voice in decision-making. “The face of agriculture in South Asia, particularly wheat farming, is feminizing,” says Cathy Rozel Farnworth. She is a social inclusion, gender and agriculture expert working with CIMMYT’s Gender Research Unit to analyze interactions between changing gender norms and agricultural innovation.

This shift was one of the findings in a series of comparative studies conducted through GENNOVATE in three research hotspots in South Asia: Bangladesh, India and Nepal. Farnworth and co-authors from the region, CIMMYT and Glasgow Caledonian University analyzed the similarities and distinctions in each country.

Shifting rules

In Nepal, women are traditionally seen as destitute and far from equals in the farming community. However, migration of men to urban areas and to other countries has given way to more opportunities in agriculture for women in rural communities. “This translates to a fundamental change in the social structure of communities and the roles of men and women, due to the absence of men,” says Farnworth. Women in the community are increasingly taking on the challenging managerial roles that men once occupied. While women in Nepal support themselves and their families, they rarely have institutional support from rural advisory services, for example, training on new wheat technologies. On occasion, support comes from individual male extension workers, and women report that NGOs have been critical to building their sense of empowerment and entitlement. Learning networks between women farmers are also important. Overall, the gender myth that “wheat is a man’s crop” is shifting in Nepal, but extension services, researchers, the private sector and others need to catch up quickly with this new reality to help provide women with adequate support.

Wheat is also increasingly becoming a women’s crop in India, despite limited institutional support and neglect. In some locations, women are responding to male outmigration not only by increasing their work in the field, but also taking key decisions, for example on hiring labor and machinery. Some women are also driving machinery themselves. In other locations, women, though not involved in fieldwork, are trying to strengthen their participation in decision-making around wheat technologies. They have an understandable interest in what happens on the farm and in how investments will impact family income. Overall, the GENNOVATE data shows that, “Women are limited by, working with and increasingly renegotiating gender and caste identities,” says Farnworth.

In Bangladesh, a women-only agricultural organization dominated by the Santal indigenous community is strongly innovating in wheat. Interestingly, the organization is drawing in and supporting low-income Muslim women innovators as well. This case study is particularly valuable in relation to achieving Sustainable Development Goals because it shows that even though Santal women are truly “left behind” in Bangladesh, very small institutional modifications have enabled them to take charge of the organization and inspire a whole community.

Taking decisions and innovating

*Women use a mini-tiller for direct seeding in Ramghat, Surkhet, Nepal. (Photo: P. Lowe/CIMMYT)*

The driving force surrounding these cases in South Asia is the gender equality narrative. The narrative is not driven by men or external partners; rather, it is being transformed by women from within. Women have been long working in the fields; they have always been part of the wheat story. Now many women are demonstrably taking more decisions about wheat, giving them more control over their own lives and households.

GENNOVATE researchers are now looking for ways to work with women themselves, with their partners, with rural advisory sectors, the private sector, community leaders and others to address the demand for technological advances to improve their wheat harvest, including machinery. The starting point is that women need to be seen as capable farmers. Partners need to get on board and start working the new realities of “who does what,” “who decides” and “who benefits,” rather than continue subscribing to old myths. Rural women farmers have critical interests in wheat, whether they farm in the field or not. Women want and are seeking inclusion. Women are collectively expressing, “We have the right to be interested, and participate in innovating around wheat,” Farnworth states.

Avoiding the next Aral Sea: Scaling responsibly

Written by on October 11, 2018. Posted in Features.

The Aral Sea was once the world’s fourth largest inland body of water. But in 1959, Soviet premier Nikita Khruschev unfurled a plan for industrialized agriculture across Central Asia. The government constructed irrigation canals to divert water from the Amu Syr and Amu Darya rivers, the two primary feeders for the Aral Sea, to thirsty cotton fields in Uzbekistan. Today, only about two-fifths of the sea remain. Evaporation exasperated by climate change and pesticide runoff have left the remaining body of water salty and polluted.

The disappearance of the Aral Sea is a tragic story about scaling gone wrong. Larry Cooley, one of the top scaling experts in the world, describes scaling as the attempt to overcome a gap between the need for something and the extent to which that need is being met. In the case of the Aral Sea, the Soviet Union saw a need for more robust cotton production and decided to overcome the gap through large-scale irrigation.

They were successful in reaching their scaling ambition but at a high and unsustainable cost. Would Kruschev still go ahead with his development scheme if he knew it would cause irreversible ecological damage in the future? Would he still prioritize high cotton yields if he knew it would decimate the local fishing industry and leave thousands unemployed?

At the recent Scale Up Conference at Purdue University, over 200 researchers and practitioners gathered to discuss effective approaches to scaling up agricultural technologies and innovations in the developing world. The tagline read “Innovations in agriculture: Scaling up to reach millions.” Several of the presenters, however, argued development organizations should think about potential tradeoffs before trying to reach the biggest impact.

Finding the optimal scale

*CIMMYT’s scaling advisor Lennart Woltering (left) and mechanization specialist Jelle van Loon led a session. (Photo: Rachel Cramer/CIMMYT)*

CIMMYT’s scaling advisor Lennart Woltering and mechanization specialist Jelle van Loon led a session on the opportunities and challenges to scaling two-wheeled tractors in Africa, Asia and Latin America. Van Loon explained how mechanization can decrease labor costs, improve livelihoods and help farmers stay locally and internationally competitive, but he acknowledged a few potential downsides. Small tractors of this kind require fossil fuels and maintenance, and introducing mechanization to a rural community has the potential to displace jobs and shift gender roles.

Woltering explained a new tool can help researchers and development organizations think through these tradeoffs in a systematic way. The Scaling Scan, which he developed in a collaboration with The PPPLab, guides users through a series of questions and prompts them to reflect on what scaling means, what it takes to take a project to scale and what the unintended consequences could be in a particular context.

(Photo: Rachel Cramer/CIMMYT)*

The first step of the Scaling Scan is “Defining a realistic scaling ambition.” It contains a responsibility check, prompting users to consider how an intervention could affect power equity and natural resources if that scaling ambition is indeed reached. “We tried to make this check as simple as possible, but still have people anticipate what unintended consequences their scaling effort might have ten years down the line,” said Woltering.

The responsibility check includes questions like: Who are the winners and who are the losers when the innovation is adopted at a large scale? Will the scaling of the innovation affect the availability of important natural resources, such as water and land?

Woltering emphasized that development organizations should try to identify the scale that optimizes tradeoffs. “We want people to be aware that bigger is not always better,” he said.

“You might think you’re benefitting the irrigation farmers, but at the same time, the fishermen or other people might be paying the price for that,” Woltering explained. “If you’re only focused on those irrigation farmers and not the whole system, it’s easy to think, ‘Oh, we’re doing a fantastic job,’ when you’re not.”

The reasons to scale up responsibly

At the conference, Tricia Wind and Robert McLean of the International Development Research Center (IDRC) presented some of their lessons learned about responsible scaling.

“If you’re working on the problem at different scales, you need to think about the problem differently and think about the solutions differently,” said Wind. “The first principle is thinking about what scale you are starting with and what the optimal scale would be for the problems that you’re focused on solving.”

The second principle is the justification for scaling. “So stepping back from the how and thinking about the why,” she explained. “What difference would this make?” Similar to the responsibility check in the Scaling Scan, the second principle explores the issue of equity. Who would be reached by this solution, and who would be left out or even negatively affected by it?

The third principle is about coordination. McLean said, “This is about accepting that all scaling happens in a system. Are the alternative solutions? How do you displace solutions that might already exist if you try to scale something? What about the cultural norms and the institutions that exist in the area where you’re scaling, and how do you coordinate to scale responsibly?”

The fourth principle is dynamic evaluation. Maclean said an organization should learn as it scales. “It’s never going to be a 1-2-3 step process that’s going to get you from innovation to impact at scale,” he explained. “Scaling itself is also an intervention. So you have your intervention you’re trying to scale, and as you scale, systems change.”

Johannes Linn, Nonresident Senior Fellow with the Brookings Institute and another one of the world’s top scaling experts, emphasized, “Scaling is not a linear process. It is iterative with feedback loops to learn and adapt.”

During the opening reception, Woltering and van Loon congratulated Seerp Wigboldus, a senior advisor and researcher with Wageningen University, on his recently completed PhD thesis, published as a book: To scale, or not to scale – that is not the only question.

Someone asked, “What do you do if 40 people are going to be harmed by an intervention while 50 people benefit?” Wigboldus replied, “Well, unfortunately, there’s no formula for this kind of thing. There will always be tradeoffs, but hopefully we can get people to slow down a bit. We need to be transparent and justify our decisions.”

Nearly all of humanity’s greatest challenges originate from the scaling of innovations. The depletion of the Aral Sea in order to scale cotton production is just one example. Climate change and industrialization is another. By adopting a responsible scaling approach, the agricultural development sector can minimize negative impacts and side effects and seek optimal solutions.

The full version of the Scaling Scan contains detailed practical information on how and when to use this tool. A condensed, two-page version is also available. We also recommend the companion Excel sheet, which generates average scores and results automatically.

NAIROBI (Kenya) — More than 20 representatives of eastern and southern African seed companies and regulatory agencies recently took part in the demonstration of a new seed certification application that can help get quality seed to market more quickly and curb sales of counterfeit seed.

As part of an event organized by the International Maize and Wheat Improvement Program (CIMMYT) at the Kiboko research station of the Kenya Agricultural & Livestock Research Organization (KALRO) on September 17, 2018, participants field-tested a beta version of SeedAssure, a digital platform that gives automatic feedback on compliance and seed production management, along with remedy options.

SeedAssure was developed by Cellsoft, a supply chain management software company, with input from the Alliance for a Green Revolution in Africa (AGRA), the Qualibasic Seed Company, the Kenya Plant Health Inspectorate Service (KEPHIS) and CIMMYT.

“This is very useful for companies like ours, spread as we are over different countries, to manage at a distance our seed growers,” said Andy Watt of QualiBasic Seed Company, who has been testing SeedAssure on the company’s farms. “The application’s dashboard will point out which farms to visit quickly for corrections.”

Mobile innovations enhance quality and speed

For over a decade, the region’s seed sector has sought fast, cost-effective and transparent seed quality control and certification approaches for use across the value chain and the region. Seed companies often rely on under-staffed national certification agencies that may miss critical inspections or give inaccurate reports. Registration of new varieties can take many years, discouraging investment in improved seed and impeding regional trade.

Worse, by some estimates as much as 40 percent of the seed sold in eastern and southern Africa is falsely labelled or not what farmers are told they are buying. KEPHIS recently confiscated over 13 tons of “fake” seeds.

The seed sector has sought mobile innovations such as tablet-based field inspections whose data load to centralized, cloud-based dashboards.

With SeedAssure’s “traffic light” system, field inspection results for factors such as plant population will score green (complied – good quality), amber (needs improvement) or red (reject) and be readily visible to key actors in the seed certification and supply chain, according to David Laurence-Brown, SeedAssure co-developer.

“This quality assurance system can help seed companies get licenses faster, speeding product to market and greatly reducing the financial risk of getting new varieties to farmers,” said Laurence-Brown. “The vision is that all actors have access to timely and accurate data on products, licensing and trade movements, with quality control checks along the value chain.”

He said that SeedAssure features 260 critical questions in 13 seed production checklists. “Putting the right questions in the right order is crucial to determine how sustainable your seed production is,” Laurence-Brown explained.

Fixing the bugs

Participants emphasized that national and regional regulatory bodies needed to be on board.

“Advocacy has to be done at different levels, from COMESA, national plant protection organizations, big and small seed companies, and research institutes and donors,” said Kinyua Mbijjewe, a well-known figure in the African seed industry and co-creator of SeedAssure, adding that this has been underway for a year now with a positive response, and public engagement is now ramping up with partners like AGRA and USAID.

Participants also suggested simplifying SeedAssure by reducing the number of questions and the subjectivity of certain data fields. For example, they observed that a more objective method was needed for scoring pest infestations, rather than SeedAssure’s current approach of rating infestations as low, moderate or intense via visual estimation.

“This will not be adopted if it’s too complex,” said Nicolai Rodeyns, NASECO seed company, Uganda.

Developers are addressing these issues, as well as comments that the application should not mix compliance and seed production management features.

CIMMYT announced that it would offer members of the International Maize Improvement Consortium (IMIC) a one-year trial subscription to SeedAssure.

Finally, AFSTA, AGRA, CIMMYT, COMESA, USAID, and other partners are forming a SeedAssure Alliance to support testing and rollout with companies and public organizations in eastern and southern Africa.

CIMMYT shows partners in Kenya new breakthroughs in maize and wheat research

Written by Jérôme Bossuet on October 10, 2018. Posted in News.

NAIROBI (Kenya) — Members of the International Maize Improvement Consortium (IMIC) and other partners had a chance to go on a field visit to the Kiboko and Naivasha research stations in Kenya on September 18 and 19, 2018. The International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agriculture & Livestock Research Organization (KALRO) held their annual partner field days to share the latest developments in maize and wheat research.

On the first day, CIMMYT invited IMIC researchers to evaluate Material Under Development at the Kiboko site. These maize lines are not publicly released yet but are available to IMIC partners, so they can select the most promising ones for their research and crop improvement work.

Each seed company was looking for certain traits to develop new hybrid varieties. For instance, Samit Fayek, from Fine Seeds Egypt was looking for ‘erect type’ maize, as he wants higher crop density and grains that look big. Christopher Volbrecht, from Lake Agriculture in South Africa, was looking for “cobs that stick out as this is what farmers want.” Josephine Okot, from Victoria Seeds in Uganda, said that “seed companies often look at drought tolerance only, but we need now to integrate resistance to Maize Lethal Necrosis.”

Using Doubled Haploid breeding in Kiboko

Next on the tour to Kiboko, partners visited various stress-tolerant breeding materials, sustainable intensification cropping demonstrations and the Doubled Haploid facility. Vijaya Chaikam, Maize Doubled Haploid Scientist, explained how CIMMYT uses this methodology to cut down breeding time from six to two cycles, which drastically reduces costs.

According to B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program MAIZE, doubled haploid breeding is possibly the biggest innovation to speed up genetic gain since the inception of hybrid technology a century ago. “In the next 4 or 5 years, CIMMYT aims at 80 percent use of double haploid lines for new hybrid development; breeding will be faster and much cheaper that way,” Prasanna said. “For now, breeders and seed companies need to know how to use double haploid lines to cost-efficiently crossbreed with their varieties for high-quality hybrids.”

At the end of the visit to Kiboko, CIMMYT officially opened a new maize seed storage cold room. This facility will serve to keep seeds in good condition and to better manage inventory. At the opening were the director of KALRO’s Food Crops Research Institute, Joyce Malinga, CIMMYT’s Africa Regional Representative, Stephen Mugo, and CIMMYT’s Technical Lead for the Global Maize Program, Aparna Das.

Fighting Maize Lethal Necrosis and rust in Naivasha

On the second day, partners visited the Naivasha research station. There, CIMMYT presented the latest efforts to contain Maize Lethal Necrosis (MLN), a devastating maize viral disease first reported in Kenya in 2011 which caused severe crop losses across Eastern Africa, causing severe crop losses. The Naivasha research station is home to a world-class facility to screen for Maize Lethal Necrosis, jointly managed by CIMMYT and KALRO.

At the facility, maize lines are evaluated for MLN resistance. The best lines and varieties are nominated for further development and shared with partners. National Agriculture Research partners can request MLN screening at no cost, while private seed companies are charged for the service. In the last four years, more than 150,000 germplasm have been screened.

CIMMYT wheat scientist Mandeep Randhawa explained how to recognize the different types of wheat rust diseases: stem, stripe and leaf rusts. He emphasized the Ug99 black stem rust strain, which appeared in Uganda in 1998 and has since severely impacted wheat production in the region and globally. Randhawa explained how CIMMYT develops varieties resistant to stem rust using a phenotyping platform and marker-assisted selection.

These two field days were a great opportunity to showcase progress in developing more resilient maize varieties in a fast and cost-effective way. This responsiveness is crucial as pests and diseases continue to threaten the livelihoods of African smallholders. Such impact could not happen without the strong collaboration between CIMMYT and KALRO.

The Doubled Haploid Facility in Kiboko and the Maize Lethal Necrosis screening facilty in Naivasha were opened in 2013 with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation.

The International Maize Improvement Consortium (IMIC) is a public-private partnership initiative launched in May 2018 as part of CIMMYT’s mission to ramp up seed breeding and production innovations.

Linear Selection Indices in Modern Plant Breeding

New publications: Book on linear selection indices, first on the subject in thirty years

Written by Courtney Brantley on October 9, 2018. Posted in Publications.

After two years of meticulous work, the book Linear Selection Indices in Modern Plant Breeding has been released by Springer International Publishing for use by plant and animal breeders worldwide. The authors of the book, J. Jesus Céron-Rojas and José Crossa, are scientists with the Biometrics and Statistics Unit of the Genetic Resources Program at the International Maize and Wheat Improvement Center (CIMMYT). The authors saw a window of opportunity to better explain how various types of linear selection indices can be constructed, interpreted, optimized and applied in breeding through the research presented in this book.

As the first book released on the subject in over thirty years, the publisher describes it as “essential reading for plant quantitative geneticists” and “a valuable resource for animal breeders.” Its high-profile scientific contributions are expected to generate an extensive impact in the international community of theoretical and practical plant and animal breeders.

To examine classification more closely, breeders use indices to categorize traits of interest to make complete representations of desired qualities in plants and animals. Focused on the linear selection index theory and its statistical properties, breeders will be able to use phenotypic and genotypic information to assess the genetic merits of the candidates to selection.

The book is published as open access and available online.

This book is the result of financial support from the Bill & Melinda Gates Foundation, the United States Agency for International Development (USAID), the International Maize and Wheat Improvement Center (CIMMYT), the CGIAR Research Program on Maize (MAIZE)and the CGIAR Research Program on Wheat (WHEAT).

13th Asian Maize Conference launched in Ludhiana, India

Written by on October 9, 2018. Posted in Press releases.

LUDHIANA (India) — International experts on maize have gathered in Ludhiana, in the Indian state of Punjab, for the 13^th Asian Maize Conference and Expert Consultation on Maize for Food, Feed, Nutrition and Environmental Security. The conference, held on October 8-10, 2018, has attracted over 280 participants from 20 countries. The delegates come from a broad range of stakeholders, including researchers, policy makers, seed companies, service providers, innovative farmers, and representatives of development organizations and funding agencies.

In the opening ceremony on October 8, the Director of the International Maize and Wheat Improvement Center (CIMMYT) Global Maize Program and the CGIAR Research Program on Maize (MAIZE), B.M. Prasanna, discussed the current situation of maize in Asia as well as the themes of the conference. A diverse range of relevant topics will be covered, from breeding for climate resilience in maize based systems and climate-smart agriculture to socioeconomics for greater impact. “Gender and social inclusion is an important issue not only for Asia, but for the entire world. Women play a very important role in our farming systems, but women’s access to improved inputs such as seed is very low. All communities, regardless of caste or creed, need access to these inputs,” he said. The need for scale-appropriate mechanization and the importance of public-private partnerships will also be discussed.

Another topic of interest is fall armyworm, an invasive insect pest that has spread through 44 countries in Africa and was recently reported in India for the first time. “This pest can migrate very quickly, and doesn’t require visas and passports like we do. It will travel, so Asian nations need to be prepared,” said Prasanna. “However, there is no need for alarm; we will be looking at lessons learned from other regions and will work together to control this pest.”

Maize in Asia has high productivity and high demand, with maize productivity in the region growing by 5.2 percent annually, compared to a global average of 3.5 percent. However, this is not enough. “Asia produces nearly 80 million tons of maize annually, but demand will be double by the year 2050,” said the Director General of International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff. “We need to produce two times more maize in Asia, using two times less inputs, and it needs to be two times more nutritious. Climate change will make this more difficult. Continued funding for maize research is crucial. We need to work together to ensure that this research and innovation gets to farmers,” he explained.

In his welcome remarks, the director of research at Punjab Agricultural University, N.S. Bains, expressed his pleasure that the conference would be held in India for the second time, after 24 years. “What brings us together today is maize, a crop with an evolution bordering on the magical, that belongs even more to the future than to the past. Now maize leads the way in crop genomics. We are looking to use maize to solve many current challenges, which will be the theme of this conference,” he said.

The director general of the Indian Council of Agricultural Research (ICAR), Trilochan Mohapatra, discussed in detail the situation of maize in India. The country produces 25-27 million metric tons of maize per year, yet low productivity for kharif, or rainfed season, remains a challenge. “We have continuously enhanced maize productivity in India since the times of great food insecurity in the 1950s, and have tremendous scope to improve using new technologies, such as marker-assisted selection for quality in maize,” he said.

The director of the ICAR-Indian Institute of Maize Research, Sujay Rakshit, gave a vote of thanks to the conference organizers and particularly the funders that made the event possible.

At the conclusion of the opening remarks, the organizers presented the vice-chancellor of Punjab Agricultural University, B.S. Dhillon, with the MAIZE Champion for Asia Award for his pioneering work in maize breeding throughout his career. “We are so lucky to work with a crop that has contributed so much to humanity. No other crop can compare,” Dhillon said in his address to participants. He also discussed the importance of climate-resilient maize varieties to help smallholder farmers suffering from the effects of climate variability.

The remainder of the conference will address the main opportunities and challenges for maize in Asia through technical sessions covering diverse topics such as novel tools and strategies for increasing genetic gains, specialty maize, processing and value addition, and nutritionally enriched maize for Asia.

On October 10, conference participants will go on a field trip to the BISA farm in Ladhowal, Ludhiana. Nearly 100 improved maize varieties developed by CIMMYT, ICAR and public and private sector partners will be on display, in addition to scale-appropriate mechanization options, precision nutrient and water management techniques, decision tools, sensors and automation-based management systems.

At the closing of the conference, the 2018 MAIZE-Asia Youth Innovators Awards will be presented, and winners will present their research. The awards were launched in collaboration between the CGIAR Research Program on Maize (MAIZE) and YPARD (Young Professionals for Agricultural Development) to recognize the contributions of innovative young women and men who can inspire fellow young people to get involved with maize-based agri-food systems.

CIMMYT is pleased to announce the release of a set of 26 new CIMMYT maize lines (CMLs). These CMLs were developed by the CIMMYT Global Maize Program’s multi-disciplinary teams of scientists at breeding locations in sub-Saharan Africa, Latin America and Asia. These lines are adapted to the tropical/subtropical maize production environments targeted by CIMMYT and partner institutions. CMLs are freely available to both public and private sector breeders worldwide under the standard material transfer agreement (SMTA).

CIMMYT seeks to develop improved maize inbred lines with superior performance and multiple stress tolerance to improve maize productivity for resource-constrained smallholder farmers. To achieve this aim, CMLs are released after intensive evaluation in hybrid combinations under various abiotic and biotic stresses. Suitability as either seed or pollen parent is also thoroughly evaluated.

Release of a CML does not guarantee high combining ability or per se performance in all environments; rather, it indicates that the line is promising or useful as a hybrid component or parent for pedigree breeding for one or more target mega-environments. The descriptions of the lines include heterotic group classification, along with information on their specific combining ability with widely-used CIMMYT lines.

For a summary of the 26 new CMLs, please click here.

Further details on all CMLs, including the pedigrees, are available here.

A limited quantity of seed of the CMLs can be obtained from the CIMMYT Germplasm Bank. To send a request, please contact Denise Costich, Head of the Maize Genetic Resources Center: d.costich@cgiar.org.

Are advisory apps a solution for collecting Big Data?

Written by Rodrigo Ordóñez on October 2, 2018. Posted in Blogs.

Big Data is transforming the way scientists conduct agricultural research and helping smallholder farmers receive useful information in real time. Experts and partners of the CGIAR Platform for Big Data in Agriculture are meeting on October 3-5, 2018, in Nairobi, Kenya, to share their views on how to harness this data revolution for greater food and nutrition security.

Jordan Chamberlin, Spatial Economist at CIMMYT, will give his insights on best practices on electronic data capture on October 4, 2018.

NAIROBI (Kenya) — Agronomic researchers face several challenges and limitations related to data. To provide accurate predictions and useful advice to smallholder farmers, scientists need to collect many types of on-farm data; for example, field size, area devoted to each crop, inputs used, agronomic practices followed, incidence of pests and diseases, and yield.

These pieces of data are expensive to obtain by traditional survey methods, such as sending out enumerators to ask farmers a long list of questions. Available data is often restricted to a particular geographical area and may not capture key factors of production variability, like local soil characteristics, fertilizer timing or crop rotations.

As a result, such datasets cannot deliver yield predictions at scale, one of the main expectations of Big Data. Digital advisory apps may be part of the solution, as they use crowdsourcing to routinize data collection on key agronomic variables.

The Taking Maize Agronomy to Scale in Africa (TAMASA) project has been researching the use of mobile apps to provide site-specific agronomic advice to farmers through agro-dealers, extension workers and other service providers.

At CIMMYT, one of the research questions we were interested in was “Why are plant population densities in farmers fields usually well below recommended rates?” From surveys and yield estimates based on crop-cut samples at harvest in Ethiopia, Nigeria and Tanzania, we observed that yields were correlated with plant density.

What was making some farmers not use enough seeds for their fields? One possible reason could be that farmers may not know the size of their maize field. In other cases, farmers and agro-dealers may not know how many seeds are in one packet, as companies rarely indicate it and the weight of each seed variety is different. Or perhaps farmers may not know what plant population density is best to use. Seed packets sometimes suggest a sowing rate but this advice is rather generic and assumes that farmers apply recommended fertilizer rates. However, farmers’ field conditions differ, as does their capacity to invest in expensive fertilizers.

To help farmers overcome these challenges, we developed a simple app, Maize-Seed-Area. It enables farmers, agro-dealers and extension workers to measure the size of a maize field and to identify its key characteristics. Then, using that data, the app can generate advice on plant spacing and density, calculate how much seed to buy, and provide information on seed varieties available at markets nearby.

Maize-Seed-Area is developed using the Open Data Kit (ODK) format, which allows to collect data offline and to submit it when internet connection becomes available. In this case, the app is also used to deliver information to the end users.

Advisory apps usually require some input data from farmers, so advice can be tailored to their particular circumstances. For example, they might need to provide data on the slope of their field, previous crops or fertilizer use. Some additional information may be collected through the app, such as previous seed variety use. All this data entered by the user, which should be kept to a minimum, is routinely captured by the app and retrieved later.

Hello, Big Data!

As the app user community grows, datasets on farmer practices and outcomes grow as well. In this case, we can observe trends in real time, for instance on the popularity of different maize varieties.

In a pilot in western Kenya, in collaboration with Precision Agriculture for Development (PAD), some 100 agro-dealers and extension workers used the app to give advice to about 2,900 farmers. Most of the advice was on the amount of seed to buy for a given area and on the characteristics of different varieties.

Data showed that the previous year farmers grew a wide range of varieties, but that three of them were dominant: DK8031, Duma43 and WH505.

Preferred variety of maize for sample farmers in western Kenya (Bungoma, Busia, Kakamega and Siaya counties), February-March 2018.

A phone survey among some 300 of the farmers who received advice found that most of them anticipated to do things differently in the future, ranging from asking for advice again (37 percent), growing a different maize variety (31 percent), buying a different quantity of seed (19 percent), using different plant spacing (18 percent) or using more fertilizer (16 percent).

Most of the agro-dealers and extension workers have kept the app for future use.

The dataset was collected in a short period of time, just two months, and was available as soon as app users got online.

The Maize-Seed-Area pilot shows that advisory apps, when used widely, are a major source of new Big Data on agronomic practices and farmer preferences. They also help to make data collection easier and cheaper.

TAMASA is supported by the Bill and Melinda Gates Foundation and is implemented by the International Maize and Wheat Improvement Center (CIMMYT), the International Institute of Tropical Agriculture (IITA), the International Plant Nutrition Institute (IPNI) and Africa Soil Information Service (AfSIS).

New publications: What drives capacity to innovate?

Written by Emma Orchardson on September 27, 2018. Posted in Publications.

Involving diverse segments of a target population in agricultural innovation interventions allows for more inclusive and equitable processes while stimulating local innovation and development outcomes. But what are the key characteristics of rural innovators? And how are their experiences similar for women and men, and how are they different?

To examine these questions, a team of researchers from CIMMYT, collaborating CGIAR centers, and Wageningen University and Research conducted individual interviews with 336 rural women and men known in their communities for trying out new things in agriculture. The results of this study are collected in 84 GENNOVATE community case studies from 19 countries across Africa, Asia, and Latin America.

Building on study participants’ own reflections and experiences with innovation in their agricultural livelihoods, the research team combined variable-oriented analysis with analysis of specific individuals’ lived experience. The study provides in-depth knowledge on how the characteristics and experiences of individual innovators interlink with the social setting to facilitate or impede innovation.

Results indicate that factors related to personality and agency are what most drive capacity to innovate. Access to resources is not a prerequisite but an important enabling aspect. Women have great potential for local innovation, but structural inequalities mean that men are often better positioned to access resources and leverage support – as a result when women challenge the status quo, men’s support is important.

Read the full article in the Journal of Gender, Agriculture and Food Security: “What drives capacity to innovate? Insights from women and men small-scale farmers in Africa, Asia, and Latin America”

This paper draws on data collected as part of GENNOVATE case studies funded by the CGIAR Research Programs on Wheat, Maize, Grain Legumes, Humid Tropics and Rice, as well as RTB (Roots, Tubers and Bananas), A4NH (Agriculture for Nutrition and Health) and FTA (Forests, Trees and Agroforestry).

Development of research design and field methodology was supported by the CGIAR Gender & Agricultural Research Network, the World Bank, the governments of Mexico and Germany, and the CGIAR Research Programs on Wheat and Maize. Data analysis was supported by the Bill & Melinda Gates Foundation.
