HARARE (CIMMYT) — In its continuing efforts to increase the productivity of maize systems in southern Africa, CIMMYT held seed fairs in two districts of Zimbabwe in September to promote the sharing of information and knowledge about new seed options for farmers and to encourage farmer-to-farmer information exchange.

At the seed fairs, which are like trade fairs, farmers, seed companies, government agencies and non-governmental organizations displayed seed and technological products. The idea of the seed fairs arose out of the problem of suitable dryland crop varieties for the climate in most parts of Zimbabwe.

The main aim of the seed fairs, held in Mutoko and Murewa districts in Mashonaland East Province, was to help smallholder farmers access information that would help them make informed decisions in coping with drought and climate change adaptation. This included awareness on various drought tolerant seeds, and a new variety of nutritious pro-vitamin A maize seed available on the market. Another focus of the seed fairs was to promote good agricultural practices, including sustainable intensification practices such as conservation agriculture.

Funded by the Technical Centre for Agricultural and Rural Cooperation (CTA), the seed fairs were attended by more than 1,400 smallholder farmers from the two districts, eight seed companies, traditional leaders, local government officials, non-governmental organizations and policy makers, as well as CIMMYT’s regional partners from Malawi, South Africa and Zambia. Regional participation is an important component of CIMMYT’s information exchange initiative.

The seed fairs helped establish linkages among farmers, seed companies, researchers, extension agents and agro-dealers. In addition, the seed fairs provided an important avenue for stakeholders to share critical information for informed decision-making at different levels. This has boosted the farmers’ confidence and increased the sense of ownership of their own activities.

“By bringing multiple stakeholders together, the fairs helped stimulate information sharing networks that are beneficial to all stakeholders,” said Peter Setimela, CIMMYT senior seed systems specialist. He added: “Planting wrong seeds lowers harvests and threatens food and nutritional security of the smallholder farmers. In our breeding for stress tolerance, we have tested and evaluated maize varieties from different areas of Zimbabwe under local conditions, incorporated various desirable traits and developed suitable varieties for local climatic conditions.”

Mutoko and Murewa districts were selected as the first beneficiaries of this information dissemination initiative. The fairs sought to build on progress achieved in the CIMMYT on-farm trials conducted in the two districts under a different project – Drought Tolerant Maize for Africa.

Although the main focus was drought tolerant and pro-vitamin A maize, other crop seeds such as finger millet, pearl millet, sorghum, beans, Bambara nuts, pumpkin and ground nut, were also exhibited by farmers.

The farmers were given space to exhibit their own seeds. This was critical in providing an avenue for farmers to exchange seeds that are not marketed through the formal systems but which farmers like. The objective of these demonstrations was to revive local seed varieties, share information on them and acknowledge that these crops thrive in local conditions, and that they could contribute to food and nutritional security.

Mutoko smallholder farmer Anna Chirere, who actively participated in the seed fair, said: “We now know that knowledge is power. So we are going to copy this knowledge from our fellow farmers and seed houses here present.”

CIMMYT plans to make the seed fairs an annual event. This would help the farmers to continue learning from one another and enhance cooperation among the community members. Maize seed on exhibition was drought-tolerant and also included the newly released pro-vitamin A maize that is orange in color, hence the name ‘orange maize’.

In Zimbabwe, nearly one in five children under the age of five is vitamin A deficient. This deficiency can lead to lower IQ, stunting, blindness, increased susceptibility to diseases and higher health risks to mothers – and their infants – during childbirth. According to the World Bank, malnourished children are more likely to drop out of school, and have lower incomes as adults, reducing overall economic growth.

Thokhozile Ndhlela, CIMMYT maize breeder, said many people in rural Zimbabwe cannot afford expensive vitamin A-rich foods such as yellow, orange and red pigmented fruits, dark leafy vegetables, or animal products such as milk, eggs, liver and cheese.

Pro-vitamin A maize, when eaten as a staple, could provide half of the average daily requirement of vitamin A for women and children. In addition to its nutritional benefits, pro-vitamin A maize is bred to yield higher than conventional varieties and is disease resistant and drought tolerant.

Ndhlela said there were 11 varieties of the pro-vitamin A maize in southern African, six of which were already in commercial production in Zambia after a successful launch of an initial three hybrids in 2012.

NEW DELHI (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) will participate in the first International Agrobiodiversity Congress (IAC) from November 6 to 9, 2016 in New Delhi. The IAC aims to provide a common platform for stakeholders, including farmers, scientists, policymakers and industry leaders to share their experiences and knowledge in agrobiodiversity management and genetic resource conservation. The Congress is being hosted by the Indian Society of Plant Genetic Resources and Bioversity International, and co-organized by CIMMYT and the Borlaug Institute for South Asia.

“Multiple challenges in future wheat production – including heat stress, changes in rainfall and a growing threat of increased virulent diseases – will increase the demand for new varieties that can cope with stress and changing environment,” said Arun Joshi, CIMMYT’s regional representative in Asia. “This congress will focus on advances that can be made through increased diversity and targeted use of genetic resources to produce improved varieties.”

Martin Kropff, director general of CIMMYT, will give a keynote address on why effective partnerships and agrobiodiversity are needed to feed nine billion people. He will also chair a plenary session on “Agrobiodiversity for Sustainable Development Goals.” Other key themes for plenaries include agrobiodiversity for adaptation to and mitigation of climate change, intellectual property rights, access and benefit sharing, farmers’ rights, quarantine, biosafety and biosecurity and science-led innovation for agrobiodiversity management and sustainable use.

CIMMYT is also organizing a satellite session titled “Harnessing Biodiversity for Food Security and Sustainable Development.” This session will bring together numerous partners of the SeeD initiative, which seeks to unlock the genetic potential of maize and wheat genetic resources by providing breeders with a toolkit to improve targeted use in the development of high-yielding, climate-ready and resource-efficient cultivars. The session will also cover the importance of enhancing the use of genetic resources for improved agriculture, and how doing so can help meet several of the 17 U.N. Sustainable Development Goals by 2030. SeeD is a pioneering partner in the Diversity Seek initiative, which seeks synergies among projects to harness the diversity of crop species to feed humankind.

In addition to Kropff, CIMMYT speakers at the conference include Ravi Singh, distinguished scientist and head of bread wheat improvement and Kevin Pixley, director of CIMMYT’s genetic resources program. Other researchers working to improve the genetic potential of maize and wheat will also participate. CIMMYT will also host an evening reception on Nov. 7 to mark CIMMYT’s achievements over the last 50 years.

National maize stem borer mass rearing laboratory inaugurated in Pakistan

Islamabad (CIMMYT) — CIMMYT, in partnership with the Pakistan Agricultural Research Council (PARC), inaugurated the first national maize stem borer (Chilo partellus) mass rearing laboratory at the National Agricultural Research Center in Islamabad on 25 October 2016.

Maize stem borer (Chilo partellus) is a destructive insect pest of maize in Pakistan. Yield losses because of this pest are estimated to reach 10-40% and in some severe incidences up to 60% losses have been reported. Application of insecticides is one of the practices mostly used by resource-rich farmers. However, cash-trapped small scale farmers have to face the yield losses unless they apply cultural practices which vary from place to place. The other alternative, perhaps the better option, is the use of tolerant varieties. Maize germplasms that have inherent resistance/tolerance to maize stem borer not only save farmers money from the lower use of pesticides, but also help to have a greener agriculture by reducing greenhouse gas emissions.

Identification of host-plant resistance in maize is part of the commissioned projects under the Agricultural Innovation Program (AIP) for Pakistan. Under AIP, stem borer resistance maize varieties sourced from the International Institute of Tropical Agriculture (IITA) are being screened to identify the varieties best adapted to Pakistan’s maize growing ecology.

To accelerate this screening process, it was necessary to have a stem borer mass rearing facility where larvae could be produced in mass and thereafter released in maize varieties as a form of artificial infestation. “Until recently, it was not possible to conduct such activities in Pakistan due to the non-availability of such a facility. Thanks to the collaboration of PARC and CIMMYT and the generous support from USAID, we are now officially opening the first stem borer mass rearing laboratory in Pakistan,” said M. Imtiaz, CIMMYT’s Country Representative and AIP Project Leader, during his inaugural speech.

Nadeem Amjad, acting Chairman of PARC, said: “During the last couple of years, we have seen very promising results under the AIP maize program. The introduction of high yielding climate resilient maize germplasm, the distribution of protein enriched maize seeds to farmers, testing of pro-vitamin A and zinc enriched maize hybrids and the introduction of biotic stress tolerant maize varieties are among the unique interventions which were not well addressed by Pakistan’s maize sector for long.” During his concluding remarks, Amjad also added that the inauguration of the laboratory will further cement PARC’s decade’s long collaborations with CIMMYT. He thanked CIMMYT and USAID for their generous support.

The field screening under artificial infestation is showing encouraging results where some entries show more than 90% survival rate by resisting the pest attack. “We need to document the results and further check in upcoming seasons to confirm these preliminary results so that tolerant germplasm can be available to end users in the shortest time possible,” says AbduRahman Beshir, CIMMYT’s Maize Improvement and Seed Systems Specialist. The inauguration ceremony was attended by scientists and stakeholders from the public and private sector and USAID. During the inauguration, it was announced that the national laboratory will serve as a training and research center for students and researchers from the public and private sector of Pakistan.

DES MOINES, Iowa (CIMMYT) – Transforming subsistence agriculture and unsustainable farming systems into productive and sustainable operations has been the key focus of scientist Bram Govaerts, 2014 recipient of the Norman Borlaug Award for Field Research and Application at the World Food Prize

Govaerts manages the Sustainable Modernization of Traditional Agriculture (MasAgro) program at the International Maize and Wheat Improvement Center (CIMMYT), which aims to enable farmers to produce high quality staple grains in sufficient quantities to meet the needs of the Mexican market.

“Starting five years ago, MasAgro and, in particular, its work on technological innovation in farmers’ fields, have been acting upon the infamous instructions of Dr. Norman Borlaug, founder of CIMMYT and of the World Food Prize,” said Govaerts, Latin America Regional Representative of the International Maize and Wheat Improvement Center (CIMMYT)  while participating in the  Borlaug Dialogue panel “Borlaug–Rockefeller: Inspiring a new generation,” coordinated by the World Food Prize Foundation.

“Borlaug told his acolytes to ‘take it to the farmer,’ which is exactly what we have been doing through MasAgro,” Govaerts said.

On the panel hosted by Rockefeller Foundation President Judith Rodin, which included three other young researchers who are also Norman Borlaug Award for Field Research and Application laureates, Govaerts added that MasAgro has produced successful results because its applied field research and capacity building activities transfer technologies to the farm sector through decision-making processes based on reliable and objective data.

“We demand scientific excellence of ourselves because agriculture can only be transformed through innovation networks, mechanisms and smart tools that enable farmers to realize their full potential,” Govaerts said.

Each year, more than 1,000 private and public sector leaders from the international community meet in Des Moines, the state capital of Iowa in the United States, to participate in the Borlaug Dialogue. The conference precedes the presentation of the World Food Prize, which was established by Borlaug, who reached the pinnacle of his career when he was awarded the 1970 Nobel Peace Prize, in recognition of exceptional leaders who have contributed to the fight against world hunger.

Previously, three CIMMYT researchers—Evangelina Villegas, Surinder Vasal and Sanjaya Rajaram—have been awarded this important prize. This year, the World Food Prize Foundation recognized  Maria Andrade from Cape Verde, Robert Mwanga from Uganda, and Jan Low and Howarth Bouis, both from the United States, for their work developing and disseminating  micronutrient-rich crops, including the biofortified, vitamin A-enriched orange-fleshed sweet potato.

Andrew Mude received the 2016 Norman Borlaug Award for Field Research and Application for developing an insurance program for previously uninsured communities whose livelihoods depend on herding cattle, goats, sheep and camels in the remote, arid and drought-prone lowlands of the Horn of Africa. The field award is sponsored by the Rockefeller Foundation.

EL BATAN, Mexico (CIMMYT) — A new study from The International Maize and Wheat Improvement Center (CIMMYT) evaluates how elite lines of maize in tropical conditions throughout Latin America perform under abiotic stresses like drought, nitrogen (N) deficiency and combined heat and drought stress.

By 2050, demand for maize is predicted to double in the developing world, and cereal production will need to greatly rise to meet this demand. However, drought and N deficiency are common detrimental factors towards achieving this goal throughout the developing world. The development of new maize germplasm able to tolerate these stresses is crucial if productivity in maize-based farming systems is to be sustained or increased in tropical lowlands in Latin America and elsewhere.

The authors found that only a few lines were tolerant across these conditions, which re-emphasizes the need to separately screen germplasm under each abiotic stress to improve tolerance. Based on high best linear unbiased predicted general combining ability, they found it will be possible to develop hybrids tolerant to multiple abiotic stresses without incurring any yield penalty under non-stressed conditions using these inbred lines. These elite lines can immediately be used in tropical breeding programs in Mexico, Central and South America, and sub-Saharan Africa to improve tolerance to abiotic stress to ensure food security in a changing climate.

Growing more with less: Improving productivity, resilience and sustainability in Africa

HARARE, Zimbabwe (CIMMYT) – “Rain patterns have changed tremendously,” says Dyless Kasawala, a smallholder farmer in Kasungu district, Malawi. “It’s different from the old days when you would be sure of a great harvest after the rains.”

For more than three decades now, life has not been easy for Kasawala and thousands of other smallholder farmers in this harsh, dry environment. Kasawala’s story is common throughout eastern and southern Africa. Observations by smallholder farmers confirm scientific evidence that shows climate change is occurring at an alarming rate, and could leave 50 million people in the region hungry by 2050.

From 1900 to 2013, droughts killed close to one million people in Africa, with economic damages of about $3 billion affecting over 360 million people. Such droughts are a clear sign of the high yield variability that impedes escape from poverty and hunger for millions of Africans. Climate change could also result in a 40 percent increase in the number of malnourished people in sub-Saharan Africa by 2050, according to the Alliance for a Green Revolution in Africa.

Sub-Saharan Africa must become resilient to climate change effects like variable and severe drought and rainfall to ensure future food security. Practicing sustainable farming techniques can help small-scale farmers adapt to these challenges.

Across the world, more farmers are beginning to practice sustainable intensification (SI), which offers the potential to simultaneously adapt farming systems to climate change, sustainably manage land, soil, nutrient and water resources, improve food and nutrition security, and ultimately reduce rural poverty.

In practice, SI involves such conservation agriculture (CA) practices as minimal soil disturbance, permanent soil cover and the use of crop rotation to simultaneously maintain and boost yields, increase profits and protect the environment. It contributes to improved soil function and quality, which can improve resilience to climate variability. The cropping systems CIMMYT promotes can be labelled as climate-resilient, according to the U.N. Intergovernmental Panel on Climate Change.

“We received little rain this year, but we’ll still have enough food,” says Kasawala, who is participating in a project led by the International Maize and Wheat Improvement Center (CIMMYT), which aims to increase farm-level food security and productivity through SI.

Kasawala was one of the first farmers to practice sustainable intensification in her district in 2010. She has managed to improve soil fertility in her fields, increase her maize yield and improve her household food security.

“Farmers have a number of technological options, but ultimately they have to make informed decisions on which technologies to adopt,” said Eric Craswell, co-chair of CIMMYT’s Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project steering committee. Such farmers as Kasawala who practice CA through SIMLESA participate in on-farm trials, which compare CA to conventional farming practices, test different levels of herbicide use and maize-legume crop rotations.

According to SIMLESA’s project leader Mulugetta Mekuria, there is evidence that shows new drought-tolerant maize varieties when coupled with SI bring even greater benefits to farmers. For example, combining elite drought-tolerant maize with direct seeding systems can improve the performance of maize by more than 80 percent. Now, nearly 650 maize and legume varieties, approved by farmers and selected by over 40 local seed companies, are being commercially distributed in the five SIMLESA countries (Ethiopia, Kenya, Malawi, Mozambique and Tanzania).

Zero tillage – a CA practice that directly sows seeds into unplowed soil and the residues of previous crops – has helped farmers cut planting time in half, allowing them to engage in other economic activities.

“Sustainable intensification is the only option to feed the extra two billion people by 2050, when resources are limited,” said John Dixon, principal advisor/research and program manager for the Australian Centre for International Agricultural Research (ACIAR)’s Cropping Systems and Economics program. ‘’Now is the time to scale-up by taking our research to farmers through extension, non-governmental organizations and farmers’ associations.”

Through 2018, CIMMYT will focus on bringing sustainable intensification to even more farmers throughout eastern and southern Africa. Collaborative work with farmers, extension agencies, non-governmental organizations, universities and agribusiness is expected to improve maize and legume productivity by 30 percent and reduce expected yield risk by 30 percent in about 650,000 rural households over a period of 10 years.

CIMMYT’s Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project is funded by the Australian Centre for International Agricultural Research (ACIAR) with strong collaboration from National Agricultural Research Systems (NARS) and a wide range of private, university, public sector and non-governmental organizations. It aims at increasing farm-level food security and productivity in the context of climate risk and change.

Strategizing for the future: adapting to a changing agricultural landscape

Forging major change is never simple, but one of my top priorities upon taking the helm at the International Maize and Wheat Improvement Center (CIMMYT) as director general last year was to develop a new five-year institutional strategy. CIMMYT must continuously change in order to adapt to an increasingly complex world and address urgent agricultural challenges. Not only do almost 800 million go to bed hungry each night, but to cite just a few examples, this year severe drought in southern Africa exacerbated by an El Niño weather system took its toll on crops, deadly wheat blast disease emerged in South Asia for the first time and scientists ratcheted up the fight against virulent maize lethal necrosis disease.

To learn more about the CIMMYT work environment, I sent an email to our key donors and partners seeking answers to some simple questions: What is CIMMYT doing well? What can CIMMYT do better? What new areas of research or collaboration should we explore? I met with staff at headquarters near Mexico City and visited regional offices to get a well-rounded set of responses. The answers I received have become the basis for the new CIMMYT Strategic Plan 2017-2022: “Improving Livelihoods through Maize and Wheat Science.”

From crops to agri-food systems

The new strategy marks a shift in thinking of maize and wheat simply as crops, recognizing that they play a major role in agri-food systems in which they operate. Modern agriculture is increasingly diverse, complex and unpredictable and we need to look beyond science alone to understand the ecological, economic and social forces that are driving change in farming systems. The shift from commodity-based research to an integrated approach centering on agri-food systems is a critical change allowing our community to work more effectively to strengthen food security, reduce poverty and enhance human nutrition.

Contributing to international development goals

Simultaneously, as CIMMYT has been undergoing changes, the CGIAR system of agricultural research centers is also going through a transition. The aim is to improve efficiency, benefiting relationships with our global network of donors and partners. These changes build on past successes, articulating  an ambitious new direction known as the “CGIAR Strategy and Results Framework 2016-2030” We have gone through a process of refining our strategy to ensure alignment with the CGIAR strategy and the U.N. Sustainable Development Goals. The strategies emphasize the need to assign higher priority to reducing malnutrition, empowering female farmers, developing new public-private partnerships and sharing knowledge with partners and farmers.

A new strategic direction

The new strategy identifies four interlinked areas of work, each highlighting CIMMYT’s strengths: scientific excellence; impact through partnerships; capacity building and the “ONE CIMMYT” concept, which reflects efforts to synthesize both internal and external activities. To achieve scientific excellence we will further develop our practice of conducting research of the highest quality and create innovations that farmers can readily put to use. CIMMYT will steadily improve the scope and quality of partnerships to accelerate the adoption of technology. CIMMYT’s leadership of the CGIAR Research Programs on MAIZE and WHEAT and the Excellence in Breeding Platform, which will help modernize breeding programs in the developing world by providing access to cutting-edge tools, services, best practices, application-oriented training and practical advice.

These initiatives will form a key part of a new partnership strategy. By creating agricultural knowledge communities, CIMMYT develops capacity and empowers collaborators to help farmers advance to a more food-secure, sustainable future. Finally, “ONE CIMMYT” values have far reaching implications on the way we work, unifying teams and building a common understanding across regions.

Launching this strategy marks the beginning of an evolutionary way of working, which will continue over the next five years to 2022. Its successful implementation requires collaboration across disciplines and the involvement of our vast network of partners. As we move forward, I will continue to consult with key stakeholders to gather insights and assessments about how we can continue to create even more impact in farmers’ fields.

I hope that you will join us.

Gazing into the crystal ball at the future of food: Nutrient-dense maize and wheat

Gideon Kruseman is CIMMYT’s ex-ante and foresight specialist.

Over the next few decades, projections indicate global population will grow from more than 7 billion to more than 9 billion people by 2050. A large proportion of that world population will be living in low- and middle-income countries in urban environments – often huge — cities.

In India, the country with the largest rural population, for instance, the percentage of urban population is expected to increase from 37 percent in 2011 to 56 percent by 2050. Globally it will grow from 55 percent in 2011 to 70 percent in 2050. The trends we anticipate in India are comparable to Africa as a whole where urban population is projected to increase from less than 40 percent to around 55 percent, although there are differences between countries and regions.

Meeting the sustainable development goals (SDGs) established in 2015 by the United Nations and the global community will be challenging. The 17 goals with 169 targets aim to solve problems related to climate change, hunger, education, gender equality, sanitation, jobs, justice and shared peace by 2030.

In particular, SDG 2, which aspires to eliminate hunger, and SDG 3, which aims to establish good health and well-being, will be challenging even if we concentrate only on climatic, environmental and biophysical constraints. If we also take into account all the implications of urbanization and economic growth on diets and dietary change a new dimension of complexity becomes apparent.

Whether model calculations are based on current consumption patterns and trends, healthy diets or a variety of ecological sustainability criteria, maize and wheat will play a significant dietary role. Currently, these two staple crops feed two-thirds of the world population and will continue to be the main supply of energy in human diets in all scenarios.

However, scenarios for maize and wheat will not ensure decrease in quantitative and qualitative malnutrition unless we act upon projected future demands now. Diets, dietary change and their effects on health and nutritional status form complex interactions with socio-economic and environmental drivers.

In the future, diets will inevitably change as they have in previous decades. Basic commodities in food consumed in urban areas require different traits than food consumed in rural areas where the chain between production and consumption is shorter. The reason for this is that in rural areas in low and middle income countries staple grains are milled and processed locally, while in urban areas people tend to eat industrialized processed or pre-processed food.

In urban areas in Africa and South Asia wheat-based products are starting to replace traditional staples such as maize and rice to some extent. Moreover, research reveals that in urban centers people tend to eat energy dense food, which can help prevent quantitative malnutrition in terms of calorie intake, but does not ensure a healthy diet. Healthy eating requires a wide range of nutrients that traditionally are found in diverse foods. When people opt for less diversity and more convenience, this requires nutrient-dense as well as calorie-dense food. A significant trend that points to convenience food is the increased consumption levels of snacks and fast food, in low- and middle-income countries.

Maize-based snacks are important components of urban diets. Moreover, maize is a key ingredient found in convenience food made by the food industry in the form of starch and syrup. Ensuring that maize and wheat can meet nutritional demands in less diverse diets requires the introduction of new traits into the varieties comparable to the ongoing efforts of maize and wheat biofortification at the International Maize and Wheat Improvement Center (CIMMYT).

The development of nutrient-dense varieties takes time since they must also incorporate traits that address environmental conditions, climate change and resistance to pests and diseases as well as feature favorable post-harvest characteristics such as milling and processing quality.

Crucial to this process are the genetic resources that allow the traits to be combined in the breeding done at CIMMYT.

How do we do this? Billions of seeds, expertly and carefully conserved for humankind, are housed in our seed bank. They are freely available to breeders and other researchers around the world who may use them to uncover solutions to some of the challenges that face humanity in the future. Any one seed could help secure the food of our future.

While the potentially desirable traits hidden in the seeds in the seed bank are very valuable, there are costs involved in maintaining this diversity. Diversity is important for finding traits that will allow maize and wheat to be more nutritious than they are already today and so aid in meeting the demands of the future. Today, everyone can be part of this future by joining the “save a seed movement.”

Changing the conversation surrounding food and agriculture with Tamar Haspel

MEXICO CITY (CIMMYT) — A few hands jabbed into the air. Tamar Haspel, a columnist for the Washington Post, had asked a room of more than 1,000 scientists, researchers, economists and agriculture experts a simple question: “Who here has changed their mind on an issue in the past year?”

SAMSUNG CSC
Tamar Haspel, Washington Post columnist, addresses the crowd during her keynote speech at the CIMMYT 50 conference.

Haspel, author of “Unearthed,” a column in the Washington Post newspaper that focuses thematically on the intersection between food and science, was delivering a keynote address at a three-day conference hosted by the International Maize and Wheat Improvement Center (CIMMYT) to celebrate the nonprofit’s 50th anniversary.

Haspel’s speech urged those in the science-agricultural industry to take a closer look at opinions unlike their own and to have constructive conversations in hopes to improve and change the current public conversation about agriculture.

Q: When did you first start writing about food, science and agriculture?

I’ve been writing about food for 20 years, really focusing on nutrition and health, but about five years ago my husband and I moved from New York City to Cape Cod (Massachusetts) and we started raising livestock, growing food and fishing. We even started a commercialized farm and because of that I know what it’s like to lose 80 percent of a crop. It behooves anybody who writes about growing food to stay connected to the idea that it has to come from somewhere and to understand the hard work and risk.

Q: What is the key message you try to push at conferences?  

The thing that I increasingly believe to be most important and really push is to get people who disagree in the same room. The best thing in the world is to be proven wrong – it means you won’t make the same mistake again. In agriculture there are so many issues people disagree on. Take the green revolution, for example, it is widely discussed within the scientific community with people on both sides of the argument giving compelling statements. Both sides may not have equal truth to them, but certainly there is some truth on both sides. I think we have to engage with people who don’t see the world the way we do, especially in the agricultural community. We have an urgent problem right now trying to feed a growing population. It’s very important we get past these stupid disagreements.

Q: Why do you think your message is received so well by scientists?  

I personally think that scientists are in the business of trying to find out what’s true. If you present something that resonates with them and they think they haven’t thought about it before it brings them some happiness. I know that for me, coming to grips with the fact that I’m an imperfect decision maker helped me and I thought that this message would resonate well within the scientific community.

Q: When did you first realize you were an imperfect decision maker?

I read “The Righteous Mind” five years ago and it was very compelling and persuasive. It completely changed the way I think about my opinions. It made me extremely careful when canvassing information and made me much more tolerant of opinions I disagree with, even if they are beyond the scientific pale.

I don’t think you can go out in the world and credibly say that genetically modified crops are dangerous to eat. But I do think the people going out in the world saying that are among the most concerned about our food system. I would love to have a constructive conversation with those people. We need people who care because honestly the road to an environmentally unfriendly food system is consumers who do not care.

We seek sources of information that share our values and confirm our views. So I say find the smartest person who disagrees with you and listen.

Weeding out the losses: Striga challenges in Kenya

SIAYA, Kenya (CIMMYT) — Every planting season presents a different kind of challenge for smallholder farmers, and for those in Siaya’s Alego sub-county in Western Kenya, the nightmare of a recurring crop-killing weed is all too real. Known by its local name kayongo, the Striga weed is one of the leading causes of crop loss, a significant dent to farmers’ livelihoods and major hindrance to food security in the area.

Over 20 million hectares (ha) of crop land in sub-Saharan Africa is Striga-infested, resulting in a whopping $ 1 billion in annual yield loss, affecting more than 100 million people. Over 1.4 million ha of East Africa’s farmland is affected by Striga, with over 340,000 ha of farmland affected in Kenya alone.

Striga, also referred to as “witch weed,” damages the crop long before it appears above ground, adding to its destructive qualities, further complicating its management. This parasitic weed attaches itself to the roots of host plants – usually cereals like maize and sorghum – then extracts essential nutrients and moisture meant for growth, causing stunted growth and crop loss. Once above ground, the Striga flower produces between 50,000-200,000 seeds, which are released into the soil and triggered to germinate when close to potential host crop roots. In the absence of host crops, the seeds remain dormant in the soil for over 20 years, only to attack in subsequent maize planting seasons when conditions become favorable.

Early signs of Striga infestation in maize include folded leaves and wilting, even when there is sufficient soil moisture. Ironically, the appearance of Striga’s beautiful purple flowers at full bloom signals the impending death of the affected maize plant.

Striga is especially prevalent in low soil fertility environments where insufficient use of agricultural inputs such as fertilizer, and cereal mono-cropping is evident. Kenya’s lake region is most affected, with at least nine species of Striga been reported in the country and Striga hermonthica – considered the most lethal of them all – is widespread in densely populated regions.

For decades, hand weeding or pulling has been practiced as a method for Striga control, however this is very labor intensive, translating to huge costs for the farmer, and is not minimally effective since damage is caused at the root of the plant.

“I learned about intercropping from an extension agent and decided to try it out on a small plot, before planting in the larger plot,” Hellen Owino shares, adding, “I think I’m now ready to plant on the larger piece of land. Even though some Striga plants emerge, I’m able to weed them out before they flower, and my yield is not severely affected.” Photo: K. Kaimenyi/CIMMYT

So, what hope is there for farmers in Striga-prone areas?

Inter-cropping, which is the simultaneous planting of two or more crops in the same field, is one of the most widely practiced Striga control measures.

“Unlike cereal roots, legume roots do not stimulate weed growth, so even though Striga seeds will remain in the soil, growth will not occur,” according to Leonard Rusinamhodzi, an agronomist with The International Maize and Wheat Improvement Center (CIMMYT), who says that growing legumes alongside maize reduces the emergence of Striga.

“On the other hand, legumes like cowpea are called trap crops because they stimulate growth of Striga, but the weed has no roots to attach to, and subsequently dies. Legumes also fix nitrogen into soils, a deterrent for Striga, which thrives in low nitrogen environments,” says Rusinamhodzi.

Two years ago, Hellen Akinyi Owino, a farmer and mother of six had given up on maize farming following consistent poor yields from her Striga-stricken farm. Even when the rains stopped mid-season, she expected to harvest up to eight 90-kilogram bags from her 0.8 ha plot, but with Striga choking up her crop, she just harvested just one bag. With her family’s livelihood in jeopardy, Owino was forced to seek alternative income generating activities. She stripped her plot of all maize and Striga plants, and put up a tree nursery instead, from which she makes money selling seedlings.

“I am a maize farmer first, so I had to figure out a way to get back to it while reducing losses from Striga,” Owino shares, adding, “I learned about intercropping from an extension agent and decided to try it out on a small plot, before planting in the larger plot.” For two years now she has planted beans alongside maize, consistently applying organic fertilizer, and stuck to a regular weeding schedule.

Another even more effective solution to Striga is planting herbicide-resistant maize.

StrigAwayℱ, or Ua Kayongo as it is known in Western Kenya, is described on Feed the Future’s Partnering for Innovation website as an Imidazolinone-Resistance (IR) maize technology package, comprising conventionally bred herbicide resistant maize varieties and Imazapyr seed treatment, an herbicide seed coating.

Since herbicide is applied to the seed coat, the recommended eïŹ€ective dose for controlling Striga is low, which is both environmentally friendly and aïŹ€ordable. Moreover, the herbicide dissipates easily from the soil before the next planting season, without any eïŹ€ect on subsequent crops.

However, if farmers were to recycle the seed, they would need to coat it again with the herbicide to control Striga, a practice which is neither feasible nor advisable at the farm level. Another challenge to uptake is that the IR maize starts off poorly, often looking as if it is nitrogen deficient, and may discourage farmers from taking up IR technology.

CIMMYT and partners’ efforts towards Striga management include both good agronomic practices and promotion of herbicide-resistant maize. So far, 12 herbicide resistant varieties have been released in East Africa, and seven hybrids released in Kenya and Tanzania. On-farm experimental trials give farmers first-hand experience of how these varieties perform, and hope that the lethal weed will be contained.

HARYANA, India (CIMMYT) — In the intensively cropped region of northwest India, poor management practices – especially residue burning after the rice season – often results in environmental degradation, severely affecting soil and human health. Residue burning is a major issue not only for agriculture, but for society as a whole. It cannot be dealt with in isolation and technology alone is not sufficient to address this challenge.

Arpana Services, a leading NGO in Haryana involved in promoting micro-enterprise programs by motivating women’s self-help groups, is working together with the International Maize and Wheat Improvement Center (CIMMYT) to generate awareness among women about climate-smart practices. In view of the forthcoming wheat sowing season, two field days aimed at discouraging residue burning were held by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) on 18 and 25 September 2016 in the Taprana and Sangoi villages of Haryana, India. The events brought together around 2,000 women from villages across the state.

Aiming to foster climate-smart agriculture, the events promoted zero-tillage wheat and highlighted the adverse effects that residue burning has on soil physiochemical and biological properties. Demonstrations showed how the Happy Seeder and other zero-tillage machines reduce production costs, save water and increase yields. The field days also focused on reducing soil degradation and human health hazards by improving soil nutrient content and decreasing hazardous gas emissions. Citing the success of 27 climate-smart villages across Haryana, H.S. Jat, CIMMYT scientist, stressed the need to conserve natural resources and develop climate-resilient cropping systems.

Another part of the collaboration involves ensuring women farmers are financially independent. For example, Aruna Dayal, director of Arpana Services, stated that working together with CIMMYT will provide innovative solutions to women farmers who need to repay loans, while diversifying income and promoting savings. At the end of the field days, the highly motivated women took an oath not to burn crop residues on their fields and to educate other fellow farmers about the harm burning can do.

Tackle food insecurity with homegrown education, Food Prize delegates say

DES MOINES, Iowa (CIMMYT) – Africa must develop a strong educational infrastructure to address the challenges of poverty, malnutrition and food insecurity, said experts at the World Food Prize Borlaug Dialogue in Des Moines, Iowa, recommending reforms at both the institutional and individual level to help smallholder farmers.

Almost 220 million people of the 1.2 billion people who live in Africa are undernourished. In sub-Saharan Africa, which lags behind regional and global trends, hunger affects about one out of every four people, according to the U.N. Food and Agriculture Organization.

“African countries must become more self-reliant when it comes to education, building on historical achievements to establish a strong infrastructure – not focused only on academic research, but with a practical ‘science for impact’ component as well,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT).

“Many people think education and capacity building are just about training or earning a doctoral degree, but it’s more extensive than that. It’s important to develop a proper framework for training individuals and institutions to ensure countries can achieve development goals.”

CIMMYT trains scientists throughout the developing world to become maize and wheat breeders. In Africa, where CIMMYT conducts 40 percent of its work, a screening facility for maize lethal necrosis disease and a center for double haploid breeding are also used as training facilities for capacity building, also helping to bolster national agricultural systems.

Kropff, who served as rector of Wageningen University and Research Center in the Netherlands before joining CIMMYT in 2015, is laying the groundwork for a “CIMMYT Academy.” The academy will pull together a range of existing training programs, uniting them into a coherent set of activities affiliated with universities throughout Africa to help breeders learn a variety of skills that can broaden their knowledge base.

“The key is to take a unified approach, sometimes a maize or wheat breeder needs also to learn technological and socioeconomic aspects of the work — we need integration – a more well-rounded approach – to really have impact,” Kropff said, adding that each innovation has a socioeconomic component and technological component.

“If we want to help countries in Africa struggling to establish a functional seed distribution system, we have to involve the private sector, so we also need to train people to become entrepreneurs,” he added.

FOUNDATION AND GROWTH

In the 1960s and 1970s, the international community helped set up the first educational development programs throughout Africa creating leadership candidates who subsequently trained many people, said Gebisa Ejeta, the 2009 World Food Prize laureate whose drought-resistant sorghum hybrids have increased food supply for millions of people throughout sub-Saharan Africa. Over time, these programs have provided the necessary foundation upon which to build institutions, he said.

“Nothing is more foundational for development than having native capacity at the human level as well as at the institutional level to really take more experiential learning forward and that way also to benefit greatly from development assistance,” Ejeta added. “Otherwise, it becomes an activity of external programs coming in and out.”

Africa has benefited over the past 10 years from being part of a new global landscape, Ejeta said, pointing to the expansion of infrastructure resulting from assistance from China, the World Bank and the African Development Bank. Simultaneously, Africa is also beginning to invest directly internally.

“Africa needs to benefit from valuable lessons from China, India and Brazil,” Ejeta said. “Each one of them is different, but the common denominator is that they all invested systematically in human and institutional capacity building in their countries to really drive involvement processes taking place to bring about transformative change.”

We need to shift the center of gravity to African governments and scientists, said Joyce Banda, who served as president of Malawi from 2012 to 2014, adding that a major challenge is a lack of extension – many people don’t know how to properly grow crops, use technology or about improved seeds due to a lack of farmer education.

Good agricultural production goes side-by-side with good governance, Banda said. “We need to fight and make sure that our resources are safe for the benefit of agriculture and food security across Africa. Africa needs to educate for change because men are eating first, best and most, but women are growing the food, storing the food, processing the food, cooking the food and eating last and less.”

The average age of an African farmer is 60, but 65 percent of Africans are young people, Banda said, adding that it is a lost opportunity if young people aren’t introduced to agriculture and trained.

CONFRONTING RISKS

Comprehensive individual and institutional capacity building can demonstrate modern agricultural techniques to inspire younger people to embrace farming, said Bram Govaerts, strategy lead for sustainable intensification in Latin America and Latin America Regional Representative at CIMMYT.

“Farmers must be made aware of new farm technology, taught how to apply scientific research to agricultural practices and get opportunities to innovate – education can facilitate the creative process, said Govaerts who won the 2014 Borlaug Award for Field Research and Application endowed by the Rockefeller Foundation and presented by the World Food Prize foundation.

“We need to first make sure partners can produce enough nutritious food for their families and then connect them to networks that can track data and crops all the way from farm to consumer,” he said. “We need to take a holistic approach to innovative post-harvest processes.”

For example, a small sensor placed in a post-harvest storage silo could measure temperature and humidity to protect the crop, but can also connect to a market network, allowing farmers to easily find buyers and prevent food waste.

“Millions of farmers in African countries are suffering from poverty, malnutrition and food insecurity, and a lack of technology prevents them from maximizing their potential contributions to their families and communities,” Govaerts said.

“I’m more and more convinced that change is going to come from innovation networks and the enabling tools that will generate them.”

Biofortification to fight “hidden hunger” in Zimbabwe

HARARE, Zimbabwe (CIMMYT) – Annually, vitamin A deficiency affects between 250,000 and 500,000 vulnerable and malnourished young people with early-life blindness worldwide. Half of these people die, according to the World Health Organization. The goal of completely eradicating vitamin A deficiency – mainly in Africa and Southeast Asia – remains a big challenge.

“There is very good evidence that vitamin A deficiency leads to an impaired immune system and can even have an impact on brain development,” said Thokozile Ndhlela, a CIMMYT maize breeder in southern Africa, addressing about 1,400 people at a seed fair event in Mutoko and Murewa districts of Mashonaland East province in Zimbabwe.

“But effective science can make a huge difference by enriching staple crops such as maize with pro-vitamin A and providing subsistence farming households with nutritionally enhanced food, ” Ndhlela explained to the audience, which included smallholder farmers, private seed companies, non-governmental organization representatives, traditional leaders, members of parliament and government officials.

In Zimbabwe, nearly one in every five children under the age of 5 are Vitamin A deficient. While vitamin A is available from a variety of sources, such as yellow, orange and red pigmented fruits, dark leafy vegetables, or animal products such as milk, eggs, liver and cheese,  these are often too expensive or unavailable in Zimbabwe’s rural areas, where 70 percent of the population live.

As part of efforts to address this nutritional challenge, CIMMYT and the CGIAR HarvestPlus research program are working with Zimbabwean researchers to develop maize varieties with high beta-carotene content.

“Beta-carotene, which is converted in the body to vitamin A is naturally found in maize,” said Ndhlela. Maize that is rich in beta-carotene is also orange in colour.

Since 2002, CIMMYT and CGIAR have been working on biofortification to enhance the micronutrient content of maize to support a fortification strategy launched by the Zimbabwe government in November 2015 through an agro-based initiative managed by farmers.

The improved orange maize varieties are bred to have some of the important traits such as high-yield potential, disease-resistance, and drought-tolerance, thereby reducing farmers’ vulnerability to effects of drought and other stresses, such as heat. This represents one promising strategy to enhance the availability of vitamins and minerals for people whose diets are dominated by micronutrient-poor staple food crops.

Orange maize – when eaten as a porridge-like staple food known as sadza in Zimbabwe – could provide half of the average daily requirement of vitamin A for women and children. This maize is bred specifically for human consumption compared to yellow maize, which is mainly for animal feed.

“Our focus is on hidden hunger, caused by insufficient mineral and vitamins in the diet – that is the major hunger problem Zimbabwe faces today,‘’ says Tendayi Mutimukuru-Maravanyika,’’ HarvestPlus Zimbabwe country manager.

CIMMYT together with HarvestPlus, Zimbabwe’s Department of Research and Specialist Services, and other partners have released the ZS242 maize variety in Zimbabwe. An additional three hybrids are expected to be released in the country by end of October 2016. Regionally, six varieties have been released in Zambia, and four in Malawi.

Farming households have benefited from the orange maize in 13 districts: Mutare, Makoni, Mutasa, Mount Darwin, Guruve, Shurugwi, Gokwe South, Kwekwe, Mutoko, Murewa, Zaka, Bikita and Marondera. The intention is to have the production and consumption of these crops scaled up to the national level through collaboration with the private sector. In the 2015-2016 cropping season, 73 tons of orange maize seed was distributed to eight districts and about 30,000 households benefited.  Out of the 13 districts, CIMMYT set up demonstration plots in five districts, of which seed fairs were held in two districts.

Demonstrations and field days are organized in various districts to create awareness, educate and train farmers on how to produce the crop and showcase good agricultural practices. “We also train partners to ensure that the product gets to the intended beneficiary, the consumer, in a way that contributes to their health,’’ said Lister Katsvairo, HarvestPlus southern Africa regional manager.

Due to a general preference for white maize, encouraging the acceptance of the orange maize variety remains a challenge often overcome when consumers taste it, according to Katsvairo. Consumers prefer the orange variety once they understand the benefits of vitamin A in their diets. In addition, people believe that yellow and orange maize are the same, but the two breeds are different in taste and colour. “They both have the same nutritional value, but orange maize contains more vitamin A compared to yellow maize, ‘’ Katsvairo said.

Douglas Makuvire, Murewa district agricultural extension officer, says most children in his area suffer from vitamin A deficiency, alluding to consumer fear of eating orange maize as a result of negative previous experiences with yellow maize, but said that efforts involve reassuring people of the nutritional benefit.

Murewa smallholder farmer, Donald Kure, 62, said he had a bad experience with yellow maize during the devastating 1992 drought when the government fed millions of people with it to avert mass starvation. “The taste was pathetic, ‘’ he recalls. Though Kure had mixed feelings about the orange maize he remained optimistic.  “Maybe this orange maize variety would be different,’’ he said after tasting sadza prepared with orange maize meal at the field day.

EL BATAN, Mexico (CIMMYT) — A study from CIMMYT scientists has revealed new insights on the respective benefits of conventional tillage (CT) and zero tillage (ZT) in north-west India.

Degradation of natural resources, increasing farm labor scarcity, and high production costs are major threats to north-west India’s rice-wheat cropping system.

Sustainable intensification practices, like switching from puddling then transplanting of rice to dry seeding, together with changing from CT to ZT for wheat with surface retention of rice residues, have proven to be very effective in maintaining or even boosting crop yields while preserving environmental resources.

However, whether using ZT for both crops brings additional benefits to either crop is not known. The effects of surface retention of rice residues in wheat on the subsequent DSR crop are also unknown, nor how this is affected by tillage for DSR.

In response, a field study was conducted during 2012-2014 to investigate the interactions between CT and ZT for rice and wheat, and both conventional and sustainable rice residue management, on the performance of a dry seeded rice-wheat system.

Researchers found that while surface retention of rice residues improved the growth of ZT wheat and this effect appeared early during the first crop, rice residue retention in wheat had an adverse effect on growth of the subsequent DSR crop in the first year. In addition, tillage treatment for rice did not affect wheat performance, and vice versa, over the first five crops.

Wheat training foundation offers hope to end rural poverty

Roy Cantrell, Jeannie Borlaug Laube, Perry Gustafson, Jessie Dubin, Manel Othmeni , Amor Yahyaoui, panelists from the global wheat community on the "Training for the Future" session at World Food Prize Borlaug Dialogue.
Roy Cantrell, Jeanie Borlaug Laube, Perry Gustafson, Jessie Dubin, Manel Othmeni , Amor Yahyaoui (L to R), panelists from the global wheat community on the “Training for the Future” session at World Food Prize Borlaug Dialogue.

DES MOINES, Iowa (CIMMYT) — In her youth, Tunisian Manel Othmeni developed an interest in interacting with plants, a fascination that later grew into a passion for wheat research.

Now, with the help of the Borlaug Training Foundation and Monsanto’s Beachell-Borlaug International Scholars Program, Othmeni is a doctoral student studying abroad with Ian and Julie King, two top global wheat scientists, at Britain’s University of Nottingham.

“If not for the training funds, I wouldn’t be here today,” said Othmeni on the sidelines of the World Food Prize Borlaug Dialogue conference in Des Moines, Iowa.

“Nowadays a Ph.D. costs a lot of money – the training gives more chances to people from developing countries.”

The Borlaug Training Foundation is an independent, non-profit foundation educating scientists from developing countries to improve food production in vulnerable areas. In the short term, the foundation aims to raise $800,000 to support global training at the International Maize and Wheat Improvement Center (CIMMYT). In the long term, the goal is to raise a $30 million endowment to expand training opportunities to other crops.

“We need to provide hope for eliminating poverty – no child should ever have to go to bed hungry,” said Jeanie Borlaug-Laube, vice president of the foundation and the daughter of the late wheat breeder and Nobel Peace Prize laureate Norman Borlaug.

Scientist Borlaug, who died in 2009 at age 95, led efforts in the mid-20th century to develop high-yielding, disease resistant, semi-dwarf wheat varieties that helped save more than 1 billion lives in Pakistan, India and other areas of the developing world.

“You are the ones who must continue my father’s legacy,” Borlaug-Laube said in an address to conference delegates. “Harness biotechnology, but don’t abandon traditional techniques.”

The foundation also aims to boost training for women scientists, develop partnerships between research institutions and universities in developed nations, provide mentorship opportunities. Wheat studies will focus on plant breeding, genetics, biotechnology, plant pathology, plant physiology and statistics.

“Going out in the field and sweating is one of the best things you can do,” said Jesse Dubin, a plant pathologist who was hired by Borlaug and retired from CIMMYT in 1999 after almost 25 years working with the wheat program.

“This kind of training is critical today and there is no funding for it. The important thing is that we’re working with the whole plant and people, not just the genome.”

Over eight years, Monsanto’s Beachell-Borlaug International Scholars Program has awarded 89 students with rice or wheat breeding fellowships, 52 of them in wheat breeding. The award is named in honor of Borlaug and rice breeder Henry Beachell.
