Having research that is high-impact is not only critical to doing excellent science that has meaning, but also a premier way to let the research community know what you are doing and reach a broader audience, according to Catherine Potenski, Senior Editor at Nature Genetics, one of the more than 70 high-quality academic journals of publishing company Springer Nature.
“Plant genomics is an exciting field that is a priority for Nature Genetics given climate change and other challenges,” said Potenski. “We look for studies with novelty, a genetics scope and resource value.”
Nature Genetics is highly selective and publishes approximately 200 papers per year. Potenski wants to make the editorial review process more productive and simple for researchers so they can share their best work.
“You should organize your paper to highlight the impact of the findings and write a cover letter that places your work in context, highlighting what gap of knowledge it fills and how others will use this research,” explained Potenski. In addition, scientists should target the right journal for their research. In case of doubt, they can send a pre-submission inquiry and work with editors.
Impact is not always immediate, and the impact factor is not necessarily a good or proven metric. “The first CRISPR articles published in the early 2000s are now very impactful, but nobody knew the impact they would have then. Just because it is not in a high-impact journal, it does not mean it is not high-impact,” she said.
Potenski shared the six questions plant researchers should ask themselves when submitting research to Nature Genetics.
Is my main approach genetic?
Your main analyses should be based on genetic screens, Quantitative Trait Locus (QTL) mapping, genome re-sequencing or other genetic approaches. If the main analysis of a paper is in transcriptomics, imaging or biochemistry, this could be considered off scope (but fine if they are secondary analyses).
Are the findings highly novel?
Your research should reflect a new method or finding that is really groundbreaking. Findings that just provide insight into a known process, are confirmatory or incremental do not meet Nature’s standards. If the finding is only new for a specific crop, that might also not be sufficiently novel.
Is there a large user group for the data?
Bigger is usually always better; you want your research to apply to or benefit as many people as possible. If the crop you are studying is widely consumed like wheat, or you have a large study scope such as large-scale GWAS (Genome-Wide Association Study) analysis, that will impact many more people than if you are studying watermelons using single QTL mapping.
Is this a very large or unique dataset?
You want large, high-quality datasets and analyses that are unique and other groups cannot easily repeat. Ideally this leads to a new approach in your field. Data that are open and easily available, and studies using the latest technologies also get priority.
Do the findings provide biological insights?
You want people reading your study to learn something new about plant biology. Instead of merely reporting domestication patterns, you want something new about the mechanisms of evolution or adaptation. Editors look for comprehensive, molecular mechanistic insight into the processes studied.
Is there evidence for crop improvement?
Editors prioritize studies with potential for crop improvement, especially in the context of climate change and food security. You want your research to be demonstrated in a crop plant, ideally in the physical plant and not in a model simulation.
A new study shows Earth Overshoot Day – the point at which the consumption of earth’s resources exceeds the capacity of nature to regenerate – is arriving faster. Thirty years ago, Earth Overshoot Day was October 15. Twenty years ago, it was September 30, and ten years ago, it was August 15. This year, August 1 marked the earliest date ever recorded.
In “How changing the world’s food systems can help to protect the planet,” CGIAR System Organization Executive Director Elwyn Grainger-Jones says one of the greatest pressure points pushing the planet to its limits is the food system. The way food is grown, produced, transported and consumed has serious consequences on the quantity and quality of earth’s natural resources. Grainger-Jones says there are numerous initiatives around the world working to transform food systems to have lower environmental footprints.
In a major wheat growing region of Mexico, CIMMYT researchers are studying how to more precisely apply nitrogen to significantly lower emissions and runoff without affecting yield.

CIMMYT staff share lessons learned at UNLEASH innovation labs with colleagues

Four young staff members from the International Maize and Wheat Improvement Center (CIMMYT) are working to bring home lessons learned at UNLEASH to foster innovation across CIMMYT programs. UNLEASH is a global innovation lab that brings together people from all over the world to transform personal insights into hundreds of ideas and build lasting global networks around the Sustainable Development Goals (SDGs). The annual event, which began in 2017 and is scheduled to occur each year until 2030, brings together 1,000 selected young talents for 10 immersive days of co-creation and problem solving.
Innovation is key to finding solutions to major global challenges such as hunger, climate change and sustainability. However, innovation cannot occur in a vacuum – the strongest and most inclusive solutions are often interdisciplinary approaches developed by a wide range of people from diverse backgrounds and perspectives. What sets UNLEASH apart from other innovation labs and processes is this commitment to diversity, as well as its focus on the Sustainable Development Goals.
While at UNLEASH 2017 in Denmark, CIMMYT staff Aziz Karimov, Daniela Vega and David Guerena were part of 200 teams that were split across 10 ‘folk high schools’ in the Danish countryside. There, they worked through an innovation process with facilitators and experts, refined their ideas to contribute to the SDGs and finally reconvened in the city of Aarhus to pitch the solutions they had developed.
Jennifer Johnson, Maize Communications Officer at CIMMYT, attended the UNLEASH Innovation Lab 2018 in Singapore last June. She worked alongside a diverse team of young people to develop solutions to improve nutrition for adolescent girls in Nepal.
The UNLEASH innovation process has five main phases: problem framing, ideation, prototyping, testing and implementing. “UNLEASH is really about finding and framing the problem,” said Vega, a projects coordinator and liaison officer for the Americas at CIMMYT and UNLEASH 2017 alumna. “Innovation is 90 percent about understanding the problem. Once you get that right, everything that follows becomes easier,” she explained.

Johnson, Guerena and Vega held a session on innovation and lessons learned at UNLEASH at CIMMYT’s Science Week 2018. Participants were walked through an abridged version of the UNLEASH innovation process to develop creative solutions to real-world problems relating to agriculture. The session emphasized diversity, respect and creativity, which are central tenets of both CIMMYT and UNLEASH.
“One of the key takeaways I got from UNLEASH was the power of diversity and collaboration,” said Guerena, a soil scientist and systems agronomist at CIMMYT who participated in UNLEASH 2017. “The diversity of the participants and collaboration lead to better solutions.”
Vega agreed. “People come from different backgrounds, geographically and professionally, and the level of cooperation and openness with no judgement is essential. We all share a similar value set, we are here because we want to make the world a better place by solving problems on a very hands-on level.”
In just one hour, participants of the CIMMYT session formed diverse teams, developed problem framings, brainstormed potential solutions and gave a three-minute pitch presenting their solution to the audience. Participants expressed extreme satisfaction with what they had learned and the innovation process they had been guided through, as well as interest in participating in similar programs in the future.
“This is a great idea, a very good experience. Often creativity doesn’t get enough attention,” said Lennart Woltering, CIMMYT scaling expert.
“This is fantastic and I’m going to adopt it. This is a great way to introduce concepts such as gender,” said Rahma Adam, CIMMYT gender and development specialist.
In the future, CIMMYT’s UNLEASH alumna hope to continue sharing their experience with colleagues and implementing lessons learned within their work.
“Unleash helps young people to think freely and differently,” said Karimov, a CIMMYT development economist whose team won second place in UNLEASH 2017’s ‘Sustainable Consumption & Production’ category which targeted Goal 12 of the SDGs. “We think innovation is something very complicated but by attending UNLEASH I realized that very simple moves can make a big change. You start believing that what is not possible is actually very possible. You just have to have will and strong desire.”

In the rural Chiweshe Communal Area, about two hours north of Zimbabwe’s capital Harare, 18-month-old Ashley Muzhange tucks into a bowl of vitamin A orange maize sadza. Sadza, a thickened porridge made from finely ground maize grain with a side of stewed vegetables, is the staple dish for rural families.
Ashley’s sadza is made from biofortified maize, conventionally bred by researchers at the International Maize and Wheat Improvement Center (CIMMYT) under the work of HarvestPlus to contain a higher amount of nutritious vitamin A.
Recent prolonged drought pushed malnutrition to levels not seen in over 15 years, with almost 33,000 children in need of urgent treatment for severe acute malnutrition, according to the United Nations Children’s Fund (UNICEF). Many experience micronutrient deficiencies, since their diets lack the vitamins and minerals required for growth and development.

According to the World Health Organization, 35.8 percent of preschool aged children suffer from vitamin A deficiency. The leading cause of preventable blindness in children, it compromises the immune system increasing the risk of death from diseases like measles, diarrhea and respiratory infections.
Biofortification increases the density of vitamins and minerals in a crop through conventional plant breeding or agronomic practices. When consumed regularly, biofortified crops generate measurable improvements in health and nutrition. The process develops crops rich in nutrients for consumers as well as the agronomic characteristics like drought and disease resistance valued by farmers. It is considered a sustainable way to bring micronutrients to populations with limited access to diverse diets.
Even though baby Ashley is unaware her sadza not only fills her stomach, but also provides her with a dose of vitamin A, her family is conscious of the benefits.
“This orange maize assures me that my daughter gets a nutritious meal and means we don’t only rely on the supplements provided by the government,” said Lilian Muzhange, her mother.
Orange the color of health
The farming family first began trialing the biofortified vitamin A orange maize in 2015 and are now growing it in place of traditional white maize. The nutritious variety contains high levels of beta-carotene, a vitamin A precursor that produces the rich orange color and once ingested is converted into the micronutrient, acting as an antioxidant to protect cells.
“Our family now prefers the new vitamin A orange maize over the white maize, as it has great health benefits for my children and granddaughter and the taste is delicious. The sadza truly is better,” said Ashley’s grandfather Musonza Musiiwa. “I was also pleased the variety is drought tolerant. Despite a dry spell in January my maize was able to yield a good harvest.”

Rural diets mainly consist of what farming families can grow, which is predominantly maize, said CIMMYT maize breeder Thokozile Ndhlela. The majority of rural households do not meet minimum dietary diversity, reliant on a cereal-based diet where meat is a rarity, the Zimbabwe Food and Nutrition Council finds.
“White maize traditionally used for the staple sadza is predominantly starch and very low in nutritional value,” said Ndhlela, who leads CIMMYT’s biofortified breeding efforts in Zimbabwe. “Biofortifying this staple crop ensures consumers have access to nutritious food season after season as farmers continue to grow it.”
Musiiwa not only sees the health and agronomic benefits of vitamin A orange maize, but has also identified its economic opportunity. The farmer is planning to increase the amount he grows to capitalize on the market he believes is set to grow.

For the new biofortified maize to be part of the food system it must be commercialized creating a full value chain, said Sakile Kudita, a demand creation researcher with HarvestPlus, a program improving nutrition and public health by developing and promoting biofortified food crops.
“Vitamin A orange maize needs to be a product millers take up and processed foods are made of, so that seed companies have an incentive to keep producing seed and farmers have an incentive to grow more than just for consumption but also sale in order to generate income,” she said.
The efforts of HarvestPlus and CIMMYT to engage government, food processors and seed companies at field days, where they learn about the nutritional and agronomic benefits and taste the orange maize have yielded success, said Kudita. Working with the government, four biofortified varieties have been commercialized since 2015.
Prime Seed Co, a subsidiary of the regional certified seed company Seed Co, was the first company commissioned by the government to commercialize vitamin A orange maize in Zimbabwe and now sells the variety Musiiwa uses in his field.

“Through our partnership with CIMMYT and HarvestPlus we are developing a market for vitamin A orange maize in Zimbabwe,” said Masimba Kanyepi, a sales manager at Prime Seed Co. “We have seen our sales improve since launching the first variety and expect an increase.”
Kanyepi is confident the market will grow following a new government regulation requiring all processed maize products to contain added micronutrients, including vitamin A, through fortification.

“Adding vitamin A to maize at the processing stage is expensive for food companies due to the cost of importing the vitamin from overseas,” said Kanyepi. “Buying vitamin A orange maize grown by local farmers already biofortified at the same price as the white variety makes economic sense.”
Food companies see the saving with Zimbabwe manufacturer, Cairns Foods, confirming it’s taking steps to include biofortified maize in its cereals and biofortified beans in its canned products.
With food processors and millers buying vitamin A orange maize there is demand for farming families like the Musiiwas to grow more, ensuring not only a boost to their health but also their livelihood, said Kudita.
Breeding for a more nutritious future

The crop diversity found in the maize species is key to nutritional gain. The plant grows in distinct environments and has developed a diverse range of valuable traits including nutritional properties.
Following a lengthy analysis of thousands of samples in the CIMMYT Maize Germplasm Bank researchers discovered native landraces and varieties from South and Central America containing increased levels of beta-carotene, explained Ndhlela. These were included in breeding programs in Africa and crossed with local varieties to ensure they were fit for the subtropical climate and were tolerant to local biotic and abiotic stresses.
Working alongside Zimbabwe’s national breeding program Ndhlela continually monitors, improves and combines dozens of characteristics, which include high yield potential, nitrogen use efficiency, and tolerance to drought, into new varieties that meet farmers’ preferences.
The most recent biofortified varieties contain about 39 percent more vitamin A compared to the first, she said.
“CIMMYT’s support through free access to maize germplasm and breeding expertise has allowed us to continue developing this nutritious maize,” said Prince Matova, a maize breeder with the Zimbabwe Ministry of Agriculture. “In the next few years we expect to release two more varieties.”
At the end of the day, farming is a business and farmers value varieties with high yield, adapted to stress conditions. The breeders are currently trialing new vitamin A maize varieties with the hope of identifying those with the potential to yield as much as the traditional white varieties and are already garnering positive feedback from farmers.

CIMMYT’s biofortified vitamin A maize breeding is supported by HarvestPlus. HarvestPlus improves nutrition and public health by developing and promoting biofortified food crops that are rich in vitamins and minerals, and providing global leadership on biofortification evidence and technology. HarvestPlus is part of the CGIAR Research Program on Agriculture for Nutrition and Health (A4NH). CGIAR is a global agriculture research partnership for a food secure future. Its science is carried out by its 15 research centers in collaboration with hundreds of partner organizations. The HarvestPlus program is coordinated by two of these centers, the International Center for Tropical Agriculture (CIAT) and the International Food Policy Research Institute (IFPRI).
HarvestPlus’ principal donors are the UK Government; the Bill & Melinda Gates Foundation; the US Government’s Feed the Future initiative; the European Commission; and donors to the CGIAR Research Program on Agriculture for Nutrition and Health. HarvestPlus is also supported by the John D. and Catherine T. MacArthur Foundation.
Despite the rising interest in advanced methods to discover useful genes for breeding in crops like wheat, the role of crop physiology research is now more important than ever, according to Gemma Molero, a wheat physiologist at the International Maize and Wheat Improvement Center (CIMMYT).
“Physiology starts with the physical, observable plant,” Molero said. “It attempts to understand plant traits and processes and, ultimately, to provide breeders with selectable traits. Take for example the plant’s ability to capture and use sunlight. This is a complex trait and there are no useful DNA markers for it, so we have to analyze how it works and then help breeders to select plants that use sunlight better and yield more grain.”
A key goal of breeders and physiologists is to boost wheat’s genetic yield potential dramatically. Progress through current breeding is less than 1 percent each year. Molero said that needs to go to 1.7 percent yearly, to meet the demand expected by 2050 from expanding and urbanizing populations.
“Science must also adapt wheat to rising temperatures, less water, and mutating disease strains, and physiology is contributing,” she added.
Applied science and fieldwork drew Molero to CIMMYT
Molero grew up near Barcelona, Spain, in a family that included a folk-healing grandmother and a grandfather whose potato fields and orchards she recalls helping to tend as a child, during summers in Granada.
“My family called me ‘santurrona’ — something like ‘goody-two-shoes’ in English — because I was always trying to help people around me,” Molero explained.
Molero completed bachelor’s and master’s degrees in biology at the University of Barcelona, Spain, by 2006. She then pursued a doctorate in eco-physiology under the supervision of José Luis Araus, a University of Barcelona professor who was also working as a CIMMYT maize physiologist around the same time.
“Araus was an example of persistence and enthusiasm for me,” Molero explained. “He sent me to the CIMMYT research station near Ciudad Obregón, in northwestern Mexico, for fieldwork as part of my Ph.D. research. That sealed the deal. I said ‘This is the type of work where I can have impact, in an interdisciplinary setting, and with fieldwork.’ ”
She joined CIMMYT in 2011 as a post-doctoral fellow with Matthew Reynolds, a CIMMYT distinguished scientist who leads wheat physiology research.
Wheat spikes hold grain and catch light
Molero has quickly made a mark in CIMMYT wheat physiology research. Among other achievements, she has spearheaded studies on photosynthesis in wheat spikes — the small ears that hold the grain — to increase yield.
“In elite wheat varieties, spike photosynthesis adds an average 30 percent to grain yield,” she said. “In wheat wild relatives and landraces, that can go as high as 60 percent. This has put wheat spike photosynthesis in the science limelight.”
Practical outputs of this work, which involves numerous partners, include molecular markers and other tools that breeders can use to select for high spike photosynthesis in experimental lines. “We have a project with Bayer Crop Science to refine the methods,” Molero said.
Molero is also collaborating with plant biologists Stephen Long, University of Illinois, and Elizabete Carmo-Silva, Lancaster University, UK, to understand how quickly wheat returns to full photosynthesis after being shaded — for example, when clouds pass overhead. According to Molero, wheat varies greatly in its response to shading; over a long cropping season, quick recoveries can add 20 percent or more to total productivity.
“This is a breakthrough in efforts to boost wheat yields,” explained Molero, who had met Long through his participation in the International Wheat Yield Partnership (IWYP), an initiative that aims to raise wheat’s genetic yield potential by 50 percent over the next two decades. “I was fortunate to arrive at CIMMYT at just the right time, when IWYP and similar global partnerships were being formalized.”
Training youth and improving conditions for young women
From a post-doctoral fellow to her current position as a full scientist at CIMMYT, Molero has supervised 13 Ph.D. students and post-doctoral fellows, as well as serving as an instructor in many training courses.
“During my first crop cycle at Ciudad Obregón, I was asked to coordinate the work of five Ph.D. students,” she said. “I’d arrive home exhausted from long days and fall asleep reading papers. But I love supervising students and it’s a great way to learn about diverse facets of wheat physiology.”
Regarding the challenges for women and youth in the scientific community, Molero believes a lot needs to change.
“Science is male-dominated and fieldwork even more,” she observed. “It’s challenging being a woman and being young — conditions over which we have no control but which can somehow blind peers to our scientific knowledge and capacity. Instances of what I call ‘micro-machismo’ may appear small but they add up and, if you push back, the perceived ‘feminism’ makes some male scientists uncomfortable.”
Molero also believes young scientists need ample room to develop. “The most experienced generation has to let the new generation grow and make mistakes.”
ROME — A new training manual is set to provide practical guidance for agricultural mechanization entrepreneurs in rural areas, where family farmers commonly lack capital to invest in the farm power required to increase food production.
The five-module training manual targeted at farm mechanization hire service providers, including youth and women, was developed by researchers at the International Maize and Wheat Improvement Center (CIMMYT) and the UN Food and Agriculture Organization (FAO) and official launched July 13 at FAO’s Rome headquarters.

It sets out a syllabus which trainers can tailor to local environments to equip entrepreneurs with essential business skills and knowledge to promote appropriate mechanization farmers need to sustainably intensify production, said Josef Kienzle, an agricultural engineer at FAO.
The manual will initially be rolled out in sub-Saharan African rural communities where improved access to agricultural mechanization is crucial, he said.
Small-scale mechanization, such as two-wheel tractor based technologies including direct seed planters, represent a shift away from destructively intensive agriculture. However, the decline of hire tractor schemes means resource-poor farmers often lack the financial means to obtain them, said Bruno Gerard, director of CIMMYT’s sustainable intensification program.
“To increase the productivity, profitability, and sustainability of their farms, family farmers need greater access to affordable yield-enhancing inputs. Hire service providers can improve access to mechanization that reduces labor drudgery and promotes sustainable intensification practices,” he said.
Sustainable intensification seeks to produce more food, improve nutrition and livelihoods, and boost rural incomes without an increase in inputs – such as land and water – thus reducing environmental impacts.
“Inclusive mechanization strategies create an enabling environment and provide a framework for making decisions on how to allocate resources, how to address current challenges, how to take advantage of opportunities that arise while in the meantime emphasize the concept of sustainable crop intensification and the roles of the private and public sectors,” said Kienzle. Farm machinery enables farmers to adopt sustainable crop production intensification practices – such as conservation agriculture – that benefit from greater farm power and precision.
The manual will be initially distributed and courses organized through FAO and CIMMYT field projects in sub-Saharan Africa utilizing local trainers and experts in machinery and agribusiness, he said. The manual is expected to be rolled out to other subregional offices and hubs in the future.

Clara Chikuni, a mother from rural Zimbabwe, has secured a stable income after starting her own mechanized shelling business two years ago. Servicing maize farmers in a 5 kilometer radius of her home, Chikuni has more customers than she says she can handle and has developed reliable employment compared to her previous job buying and selling shoes.
“There is a lot of demand for mechanized maize shelling services. I am happy I can provide a service to the community and make money to support my family,” she said. “I hope with the profits I can move into the two wheel tractor business in the future.”
“The training and support gave me the know-how and confidence to start my business,” said the mother. “Other women now ask me how I did it and I encourage them to also get involved.”
There is a market for farming mechanization services that can make a big difference for a smallholder farm and help it transition from subsistence farming to a more market-oriented farming enterprise, said FAO’s Kienzle.
Apart from hire services, mechanization creates additional opportunities for new business with repair and maintenance of equipment, sales and dealership of related businesses including transport and agro-processing along the value chain.
The knowledge and expertise of both CIMMYT and FAO combined has made this manual unique and very praxis oriented, focused on smallholder mechanization businesses, he said.

In Bangladesh, women disproportionately face social stigmas regarding appropriate behaviors and working roles which often keep women out of entrepreneurship and leadership roles and limit their roles to household chores like child-rearing and cooking. These restrictions have kept many women from reaching their maximum potential and contributing fully to the economy, especially in the agricultural sector, which has long been limited by the restricted participation of women.
Before the arrival of appropriate-scale machinery, such as the power tiller operated seeder (PTOS), seeding jute had been a daunting venture in Baliadangi in Rajbari District. The fatiguing task of preparing land for seeding, sowing seeds by digging soil and simultaneously planting posed a nearly insurmountable challenge. Today, Dipty Roy, a female LSP from the small village of Taltola, Baliadangi pushes her PTOS forward and effortlessly seeds her jute.
Roy has become a repository of knowledge concerning seeds because of her role in the operations of the seeder. She, like 74 other female LSPs, upon gaining PTOS training from CIMMYT, plans to not just be a machinery owner, but leap onto business ownership. As a successful PTOS service provider with high hopes and ambitions, Roy aspires to build a business where she employs and trains machinery operators and makes a larger contribution to agriculture.
“There is something magnificent about running one’s own business. The overwhelming feeling of taking charge and making an invaluable contribution would speak volumes for my personal growth and economic standing,” says Roy.
The channeling of resources, endeavors, hopes and optimism towards the development of women entrepreneurs has now become paramount. CIMMYT through CSISA-MI in USAID’s Feed the Future zone in Bangladesh empowers rural women to advocate for and serve the needs of their employees, to provide machinery operation training, to estimate costs and benefits and run a viable machinery driven business. The emergence of women entrepreneurs in agriculture is powerful- it can propel the rural population into self- sustaining individuals who can effectively take charge of a business and catalyze the development of the economy.
As they move closer to shattering the once impenetrable glass ceiling – they are now leading the way for a new generation of women LSPs who aspire to hold entrepreneurship roles in Bangladeshi agriculture.
In the tribal belt of Mayurbhanj, Odisha, maize cultivation is becoming increasingly popular. Thousands of acres of fallow upland areas are suitable for maize cultivation during the kharif (monsoon) season due to the availability of rain, a slopy landscape and porous red soil. As maize is considered a ‘women’s crop,’ meaning that it is mainly cultivated by women, the expansion of maize can increase women’s economic opportunities as well. The Cereal Systems Initiative for South Asia (CSISA) has worked in Mayurbhanj since 2013 to increase agricultural productivity and diversify livelihood options for farmers. One way to maximize the productivity of their arable upland areas is to cultivate maize on previously fallowed land during kharif.
In 2017, CSISA held and event in Badbil village at which 130 members of 10 different self-help groups showcased their work on commercial maize cultivation from the previous year. Members of Baitarani Maa Shibani, a women’s self-helf group from Tangabila village with a 12-year history of participating in agricultural programs in the area were impressed with the successes they saw and felt inspired to cultivate maize themselves.
After some discussion within the group, six of the 16 members decided to start cultivating maize as soon as possible. The group allowed these women to take a loan from their joint savings to cover start-up costs. Having also received support from their husbands, despite skepticism in some cases, the six women proceeded to plant maize on fallow land as villagers looked on critically.

The women approached a community resource person from a women’s group in the Sayangsidha Federation to learn how to cultivate maize, as the community resource person had already attended trainings organized by CSISA and the Department of Agriculture. They also sought guidance from other maize farmers, as well as from CSISA. One of the women worked with the state Horticulture Department and was permitted to grow crops during off-season on a 37 acre plot of land. This opportunity gave the women immediate access to land.
CSISA suggested that they only cultivate 10 acres the first year as planting in the last week of July meant they had missed optimal sowing time for maize, which runs from the first week of June until mid-July. CSISA-trained service providers helped the group complete sowing within two days, following best-bet management practices for land preparation and sowing, including integrated weed management using herbicides and power weeders, sensible fertilizer use and post-harvest management to maintain high quality dry grain. The group also visited a large CSISA and Department of Agriculture event in the tribal-dominated village of Kashipal. Interacting with other farmers and seeing their successes boosted the womens’ confidence, especially when they saw what they could achieve the following year if they sowed their crop earlier.
At the end of the season, the women harvested 11 metric tons of good quality dry grain. CSISA, the Department of Agriculture and the district administration facilitated the procurement of this grain by Venkateswara Hatchery, one of the leading poultry production plants in the region, at a price of $223 (INR 14,500) per metric ton. This group of six women farmers had invested $923 (INR 60,000) for maize cultivation and earned $2,453 (INR 159,500). They were able to repay their loan and keep the rest of the profit as savings. The women felt proud and confident knowing they had set an example for other group members and men in the village who did not believe it would work.
Following this success, in the 2018 kharif season, more farmers (both men and women) are planning to utilize fallow land for maize cultivation. This will help farmers increase their income, and improve their collective access to markets, since their total grain production will be larger and better able to meet the needs of local industry.
Unfortunately, Baitarani Maa Shibani has not been given access to the same piece of land this year, so they have planned to cultivate maize on 10 acres of their own land in the plantation area. This change in fortune mirrors the cautionary tale reflected in the experience of maize-cultivating women of Badbil village, who also found it harder to get access to leasable land following their economic success in 2016. However, women in Mayurbhanj are still optimistic. Inspired by the success of Baitarani Maa Shibani, another group, Baitarani Maa Duarsani, is now planning to cultivate maize this season.
A decade earlier in Mayurbhanj, women often did not even step out of their houses. They feared going to the market or to the bank. Now, through opportunities afforded by economic development programs and collaborations such as the one with CSISA, women often hold leadership positions in their groups, go to the bank and are active members of their village. Money earned by self-help groups is frequently used to educate children as members want their daughters to be educated and have better opportunities.
The enthusiastic women who stepped forward to cultivate maize in the face of so much uncertainty are an example of what women can achieve through collective effort, dedication, hard work and determination, as well as by tapping into the potential productivity of the fallow land around them. CSISA will continue to facilitate partnerships, technical trainings and market linkages in Mayurbhanj to support income generation amongst women’s groups and tribal communities through the cultivation of maize and companion crops.
The Cereal Systems Initiative for South Asia (CSISA) was established in 2009 with a goal of benefiting more than 8 million farmers by the end of 2020. The project is funded by the United States Agency for International Development (USAID) and the Bill and Melinda Gates Foundation (BMGF) and is led by the International Maize and Wheat Improvement Center (CIMMYT) and implemented jointly with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI). Operating in rural ‘innovation hubs’ in Bangladesh, India and Nepal, CSISA works to increase the adoption of various resource-conserving and climate-resilient technologies, and improve farmers’ access to market information and enterprise development. CSISA supports women farmers by improving their access and exposure to modern and improved technological innovations, knowledge and entrepreneurial skills. CSISA works in synergy with regional and national efforts, collaborating with myriad public, civil society and private-sector partners.

When trying to drive change in a global research organization, the science is the easy part, according to Geoff Graham, Vice President for Plant Breeding at Corteva Agriscience, a new company that brings together DuPont Crop Protection, DuPont Pioneer, and Dow AgroSciences.
“The hard thing is to change organizational culture—getting people to stop remembering how they’ve always done things and to think instead about what needs to be done,” said Graham, speaking on the topic to more than 600 international scientists and support staff at the Mexico headquarters of the International Maize and Wheat Improvement Center (CIMMYT) on 25 June 2018.
“Innovation is a process that can be managed, but it takes time and must be prioritized,” he explained, in his keynote talk during the opening session of CIMMYT’s biennial Science Week, which brings together the center’s researchers from 15 offices in Africa, Asia, and Latin America and this year focused on next-generation science and partnerships for impact.
“Innovation may require creativity, but innovation and creativity are different things,” added Graham, whose family lived in Cali, Colombia, until he was 14 and then moved to Minnesota in the U.S.
Responsible for global breeding activities at Corteva, a name derived from a combination of words meaning “heart” and “nature,” Geoff previously worked at DuPont Pioneer. He has Bachelor of Science and Master of Science degrees from the University of Minnesota, and earned a Ph.D. in genetics and plant breeding from North Carolina State University.
Below, watch an interview with Graham regarding the role of research institutions in society, how change can occur in CIMMYT, and how Corteva will support the CIMMYT-led CGIAR Excellence in Breeding Platform.

A new study from the International Maize and Wheat Improvement Center (CIMMYT) and Wageningen University examines the preferences and needs of maize processors and consumers in Sub-Saharan Africa (SSA). According to the authors, the demand for maize, a staple crop in SSA, will triple by 2050 due to rapid population growth. At the same time, the effects of climate change, such as erratic rainfall and drought, threaten agricultural productivity and the ability to meet this growing demand, while persistently high malnutrition pose additional challenges to the region. The authors suggest six objectives to enhance maize breeding programs for better food security and nutrition in SSA.
First, they recommend breeding programs enhance the nutrient density of maize through biofortification to help reduce deficiencies in vitamin A, zinc and protein. Since wheat is difficult to grow in most of SSA and expensive to import, they also suggest that programs breed to enhance the suitability of maize for making bread and snacks. The authors recommend breeding to improve maize for use as ‘green maize’ – the first crop to reach the marketplace after the dry season. If suitable green maize varieties are available, the hunger gap between seasons could be significantly reduced.
The authors’ fourth suggestion is breeding to improve characteristics that enhance the efficiency of local processing. For example, soft maize is preferred for traditional dry and wet milling, but hard maize is usually preferred for pounding or refining processes in the home. Lastly, the authors suggest breeding to reduce waste by maximizing useful product yield and minimizing nutrient losses, and breeding to reduce anti-nutrient concentrations in grains. For example, phytate or phytic acid is a naturally occurring compound found in cereals that binds with minerals and prevents their absorption. Transgenic and gene editing approaches may offer viable options for reducing phytate production.
The authors emphasize that none of these opportunities to enhance breeding strategies are “magic bullet” solutions. Sustainable, diversified crop production and post-harvest management strategies will play an important role in improving nutrition, food security and livelihoods.

Rapidly emerging and evolving races of wheat stem rust and stripe rust disease—the crop’s deadliest scourges worldwide—drove large-scale seed replacement by Ethiopia’s farmers during 2009-14, as the genetic resistance of widely-grown wheat varieties no longer proved effective against the novel pathogen strains, according to a new study by the International Maize and Wheat Improvement Center(CIMMYT).
Based on two surveys conducted by CIMMYT and the Ethiopian Institute of Agricultural Research(EIAR) and involving more than 2,000 Ethiopian wheat farmers, the study shows that farmers need access to a range of genetically diverse wheat varieties whose resistance is based on multiple genes.
After a severe outbreak in 2010-11 of a previously unseen stripe rust strain, 40 percent of the affected farm households quickly replaced popular but susceptible wheat varieties, according to Moti Jaleta, agricultural economist at CIMMYT and co-author of the publication.
“That epidemic hit about 600,000 hectares of wheat—30 percent of Ethiopia’s wheat lands—and farmers said it cut their yields in half,” Jaleta said. “In general, the rapid appearance and mutation of wheat rust races in Ethiopia has convinced farmers about the need to adopt newer, resistant varieties.”
The fourth most widely grown cereal after tef, maize, and sorghum, wheat in Ethiopia is produced largely by smallholder farmers under rainfed conditions. Wheat production and area under cultivation have increased significantly in the last decade and Ethiopia is among Africa’s top three wheat producers, but the country still imports on average 1.4 million tons of wheat per year to meet domestic demand.
National and international organizations such as EIAR, CIMMYT, and the International Centre for Agricultural Research in the Dry Areas (ICARDA) are working intensely to identify and incorporate new sources of disease resistance into improved wheat varieties and to support the multiplication of more seed to meet farmer demand.
New wheat varieties have provided bigger harvests and incomes for Ethiopia farmers in the last decade, but swiftly mutating and spreading disease strains are endangering wheat’s future, according to Dave Hodson, CIMMYT expert in geographic information and decision support systems, co-author of the new study.

“In addition to stripe rust, highly-virulent new races of stem rust are ruining wheat harvests in eastern Africa,” he explained. “These include the deadly Ug99 race group, which has spread beyond the region, and, more recently, the stem rust race TKTTF.”
As an example, he mentioned the case of the wheat variety Digalu, which is resistant to stripe rust and was quickly adopted by farmers after the 2010-11 epidemic. But Digalu has recently shown susceptibility to TKTTF stem rust and must now be replaced.
“In rust-prone Ethiopia, the risks of over-reliance on a widely-sown variety that is protected by a single, major resistance gene—Digalu, for example—are clearly apparent,” he added. “CIMMYT and partners are working hard to replace it with a new variety whose resistance is genetically more complex and durable.”
Hodson said as well that continuous monitoring of the rust populations in Ethiopia and the surrounding region is essential to detect and respond to emerging threats, as well as to ensure that the key pathogen races are used to screen for resistance in wheat breeding programs.
Hodson and partners at the John Innes Centre, UK, and EIAR are leading development of a handheld tool that allows rapid identification of disease strains in the field, instead of having to send them to a laboratory and lose precious time awaiting the results.
CIMMYT and partners are also applying molecular tools to study wheat varietal use in Ethiopia. “There are indications that yields reported by farmers were much lower than official statistics, and farmer recollections of varietal names and other information are not always exact,” Hodson explained. “We are analyzing results now of a follow-up study that uses DNA fingerprinting to better document varietal use and turnover.”
Eleven years ago this week, Apple Inc. released the iPhone. While it was not the first smartphone on the market, industry experts often credit the iPhone’s groundbreaking design with the launch of the mobile revolution. The device, its competitors and the apps that emerged with them have changed how over two billion people interact with the world on a daily basis.
The success of this revolution, however, goes far beyond the actual technology. At the International Maize and Wheat Improvement Center (CIMMYT) outside Mexico City, scaling expert Lennart Woltering points to a smartphone lying on his desk.
“We have to remember that this phone is just hardware. It is useless if you don’t have a network connection or an outlet in your house with electricity,” he says.
Woltering joined CIMMYT last year as part of the German Development Cooperation’s effort to aid the scaling-up of agricultural innovations. New, improved seeds, small-scale machinery and conservation practices can all play a role in achieving several of the Sustainable Development Goals, but Woltering says many other non-technological factors, such as markets and policies, can prevent these innovations from having significant impact.

“Many research institutes and nongovernmental organizations tend to focus on technology as the solution for everything,” he says. “But we find that 9 out of 10 cases, limiting factors have more to do with financing not being available to people, or poor policies that are hampering the adoption of technology.”
For example, CIMMYT has many initiatives in South Asia to promote conservation agriculture. Adopting no-till practices can help reduce erosion and improve soil health for better yields, but farmers who make this transition often need access to a different kind of machinery, such as the Happy Seeder, to plant their seeds. If government subsidies exist for conventional rototillers but not for the Happy Seeder, it is difficult to persuade farmers to make that economic sacrifice.
“It is a completely different ballgame in the real world, and you have to be honest about whatever fake reality you created in your project,” says Woltering.
Projects are designed in a very controlled way. They have a fixed budget and a fixed end date, and they are often shielded from the social and economic complexities that can propel or hinder an innovation from scaling.
“So if a donor says, ‘We want two million people to be reached,’ well, how are you going to do that? That’s where the Scaling Scan can help,” says Woltering.

The Scaling Scan helps an individual analyze, reflect on, and sharpen one’s scaling ambition and approach through a series of questions and prompts. It focuses on ten scaling ‘ingredients’ that need to be considered (e.g. knowledge and skills, public sector governance, awareness and demand) to reach the desired outcome.
“The Scaling Scan helps you figure out what exactly is required, what is possible, and what bottlenecks exist that you need to address in your strategy,” Woltering says.
Woltering collaborated with The PPPLab, a consortium of four Dutch institutes, to release the first version of the Scaling Scan last year. They tested it with project teams in the Netherlands, Mexico, India, Nepal and Kenya, and based on the feedback, they are now releasing a second version, which is available here.
In the trials with the first Scaling Scan, some teams realized the results they wanted to achieve were too ambitious given the circumstances. For other teams, it helped them clarify exactly what they wanted to achieve.
“Having a project objective is not enough to internalize the main goal,” says Woltering. “It also changes over time, especially if it’s a long-term project. The scaling scan can be good for an annual checkup.”
Woltering emphasizes that successful scaling requires multidisciplinary collaboration.
“If you only have a team of agronomists, you will not reach a scale of millions you want to achieve. If you only have a team of policy experts, you will not succeed,” he says. “There are professionals that can really help and add value to what we are doing.”
“It’s hard to get an agronomist and an economist in the same room together, but we’re not going to change the world if we don’t work together with others who have their specific specialty or expertise,” he says.
The Scaling Scan also includes a responsibility check through some very simple but strategic questions.
“Every system has its pros and cons – some people benefit, some do not. Some have power, some do not,” says Woltering. “So what does it mean if your innovation goes to scale? Maybe there’s a whole new power dimension.”
Successfully scaling something may have unintended consequences. There are always tradeoffs and resistance to change. Woltering says the responsibility check can help actors in the development sector to think through these questions and consider what the possible outcomes could be.
For more explanation on how and when to use the tool, we invite you to download the Scaling Scan (also available in Spanish) which contains detailed practical information. We recommend the Excel sheet (also available in Spanish) to have the average scores and results generated automatically. A condensed, two-page PDF is also available.

In an excellent example of scientific collaboration spanning borders and generations, Mustapha El-Bouhssini, entomologist at the International Centre for Agricultural Research in the Dry Areas (ICARDA), screened wheat breeding lines from the International Maize and Wheat Improvement Center (CIMMYT) under glasshouse infestations of Russian wheat aphid (Diuraphis noxia), a major global pest of wheat. At least one of the lines, which were developed through crosses of wheat with related crop and grass species, showed high levels of resistance.
“In our experiments, we did an initial screening with one replication and then a replicated test with a Pavon line and the check,” said El-Bouhssini.
Pavon is a semi-dwarf wheat variety developed by Sanjaya Rajaram, former CIMMYT wheat director and 2014 World Food Prize laureate. The version of Pavon referred to by El-Bouhssini had been crossed with rye by Lukaszewski and entered CIMMYT’s wheat genetic resource collections; the check was a popular high-yielding variety with no resistance to Russian wheat aphid.
The resistant wheat line (center) is green while all others have perished under heavy infestation of Russian wheat aphid, in the ICARDA entomology lab at Rabat, Morocco.
Pavon had been used by Lukaszewski and colleagues as a model variety for wide crosses to transfer pest and disease resistance to wheat from its distant relatives. More recently Leonardo Crespo-Herrera, CIMMYT wheat breeder, pursued this research for his doctoral studies. It was he who provided a selection of wide-cross lines to El-Bouhssini.
“Resistance to pests in wheat is a valuable trait for farmers and the environment,” said Crespo-Herrera. “It can protect yield for farmers who lack access to other control methods. For those with access to insecticides, it can minimize their use and cost, as well as negative impacts on the environment and human health.”
From an early age, Tom Hagen has enjoyed watching plants grow and solving complex problems. Now, as the enterprise breeding system manager at the International Maize and Wheat Improvement Center (CIMMYT), Hagen is combining his expertise in crop breeding and IT to help researchers and farmers be more successful.
“You could say I’m a hybrid scientific consultant – IT system architect,” said Hagen. “I will work with breeding teams to appropriately design software and then manage its development and deployment to facilitate breeding operations at CIMMYT and the International Rice Research Institute.”
The software will help breeders more effectively choose seed varieties, design field trials, collect data and analyze their outcomes. It is intended to assist farmers and extension agents as well.
“It will be able to give them advice about the appropriate seeds to use based on their specific environment and economic situation,” said Hagen. “It can also recommend ways to plant and manage their crop for better yields and higher income.”
Hagen’s interest in using computer programing to analyze large sets of biological data emerged shortly after obtaining a doctorate in plant genetics from the University of Georgia. It was the early 1990s, and bioinformatics was a new frontier. Hagen founded and managed the university’s Center for Scientific Computing and Visualization, and helped create the Bioinformatics Graduate Program.
In 1999, Hagen decided to leave the world of academia for the private sector.
“Universities are about inventing things, not applying them,” he said. “It is important to base your practice on theory, but at the end of the day, I personally think you need to apply it because otherwise – well, what is the point of it all?”
Hagen joined DuPont Pioneer, a large U.S. producer of hybrid seeds, where he and a team of designers created different technologies for breeders. Specifically, they worked on technologies that would help breeders develop a line of drought-resistant maize.
“By being in that group, I was both a scientist trying to invent and validate these methods while also designing and building the IT for that,” said Hagen.
During his last two years at DuPont Pioneer, Hagen was the architect of all analytics software. He also conducted research on crop growth modeling for predicting genotype-environment interactions for maize hybrids. This information has helped breeders, extension agents and farmers choose appropriate seed varieties for their specific environmental conditions.
Hagen joined the CGIAR Excellence in Breeding Platform (EiB) in January 2018. Led by CIMMYT, EiB aims to modernize breeding programs, specifically targeting the developing world for greater impact on food and nutrition security, climate change adaptation and development.
“I’m excited to be part of the work that’s starting to ramp up here at CIMMYT and the other CGIAR centers,” said Hagen. “I’m here to learn and engage, and do whatever I can to help others learn.”
From an early age, Tom Hagen has enjoyed watching plants grow and solving complex problems. Now, as the enterprise breeding system manager at the
