Investing in drought-tolerant maize is good for Africa

Written by Jérôme Bossuet on November 26, 2019. Posted in News. 1 Comment on Investing in drought-tolerant maize is good for Africa

Zambia’s vice-president has recently called to reduce maize dominance and increase crop and diet diversification in his country. The reality is that maize is and will remain a very important food crop for many eastern and southern African countries. Diet preferences and population growth mean that it is imperative to find solutions to increase maize production in these countries, but experts forecast 10 to 30% reduction in maize yields by 2030 in a business-as-usual scenario, with projected temperature increases of up to 2.7 degrees by 2050 and important drought risks.

Knowing the importance of maize for the food security of countries like Zambia, it is crucial to help maize farmers get better and more stable yields under erratic and challenging climate conditions.

To address this, the International Maize and Wheat Improvement Center (CIMMYT) and its partners have been developing hundreds of new maize varieties with good drought tolerance across sub-Saharan Africa. Stakeholders in the public research and African seed sectors have collaborated through the Drought Tolerant Maize for Africa (DTMA) project and the Stress Tolerant Maize for Africa (STMA) initiative to develop drought-tolerant seed that also incorporates other qualities, such as nutritional value and disease resistance.

A groundbreaking impact study six years ago demonstrated that drought-tolerant maize significantly reduced poverty and food insecurity, particularly in drought years.

A new study from CIMMYT and the Center for Development Research (ZEF) in the main maize growing areas of Zambia confirms that adopting drought-tolerant maize can increase yields by 38% and reduce the risks of crop failure by 36%.

Over three quarters of the rainfed farmers in the study experienced drought during the survey. These farming families of 6 or 7 people were cultivating 4 hectares of farmland on average, half planted with maize.

Another study on drought-tolerant maize adoption in Uganda estimated also good yield increases and lower crop failure risks by 26 to 35%.

A balancing act between potential gains and climate risks

Drought-tolerant maize has a transformational effect. With maize farming becoming less risky, farmers are willing to invest more in fertilizer and other inputs and plant more maize.

However, taking the decision of adopting new farm technologies in a climate risky environment could be a daunting task. Farmers may potentially gain a lot but, at the same time, they must consider downside risks.

As Gertrude Banda, a lead farmer in eastern Zambia, put it, hybrid seeds have a cost and when you do not know whether rains will be enough “this is a gamble.” In addition to climate uncertainty, farmers worry about many other woes, like putting money aside for urgent healthcare, school fees, or cooking nutritious meals for the family.

Information is power

An additional hurdle to adoption is that farmers may not know all the options available to cope with climate risks. While 77% of Zambia households interviewed said they experienced drought in 2015, only 44% knew about drought-tolerant maize.

This inequal access to knowledge and better seeds, observed also in Uganda, slows adoption of drought-tolerant maize. There, 14% of farmers have adopted drought-tolerant maize varieties. If all farmers were aware of this technology, 8% more farmers would have adopted it.

Because farmers are used to paying for cheap open-pollinated varieties, they are only willing to pay half of the hybrid market price, even though new hybrids are performing very well. Awareness campaigns on the benefits of drought-tolerant maize could boost adoption among farmers.

According to the same study, the potential for scaling drought-tolerant maize could raise up to 47% if drought-tolerant varieties were made available at affordable prices at all agrodealers. Several approaches could be tested to increase access, such as input credit or subsidy schemes.

How a disease without borders was contained

Written by Rodrigo Ordóñez on November 25, 2019. Posted in Features.

It’s been eight years since maize lethal necrosis (MLN) was first reported on the African continent. When it appeared in Kenya’s Bomet County in 2011, a sense of panic swept across the maize sector. Experts quickly realized that all maize varieties on the market were susceptible to this viral disease, which could wipe out entire maize fields.

Spearheaded by the International Maize and Wheat Improvement Center (CIMMYT), a rapid regional response involving national agriculture research systems (NARS), national plant protection organizations and seed sector partners was set up. The response involved multiple approaches: rigorous surveillance, epidemiology research, disease management across the seed value chain, and screening and fast-tracking of the MLN-tolerant maize breeding program.

Now, CIMMYT and its partners are reflecting on the tremendous impact of transboundary coalition to contain the devastating disease.

“Country reports show there are now much less incidents of MLN in the region. We have effectively contained this disease as no new country in sub-Saharan Africa reported MLN since Ethiopia in 2014. This is a great achievement of an effective public private partnership,” noted B.M. Prasanna, Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.

He was speaking at the closure workshop for the MLN Diagnostics and Management project and the MLN Epidemiology project on October 15-17, 2019, in Nairobi, Kenya. Experts from research, plant health and seed sector organizations from eastern and southern Africa reflected on the tremendous impact of the transboundary coalition to contain MLN across the region.

“The outbreak of the disease in Uganda in 2012 was a huge challenge as all the maize varieties and hybrids on the market were susceptible. With the support of CIMMYT and other partners in the national agriculture research systems, we got access to Bazooka, a high-yielding, drought- and MLN-tolerant maize variety that has helped in containing the disease,” said Godfrey Katwere, marketing manager for NASECO.

Until now, 19 MLN-tolerant and -resistant hybrids have been released, helping to keep the disease away from farmers’ fields and to stop its spillover to non-endemic countries in sub-Saharan Africa.

Science in action

The MLN screening facility, established in Naivasha in 2013, has been key to a better understanding of the disease and to setting up MLN hybrid tolerance and resistance breeding efforts. The facility, funded by the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture, has supported public and private partners to screen over 200,000 germplasm with around 300,000 rows of maize.

State-of-the-art epidemiology research has been carried out to identify how the disease could be transmitted and the best diagnostics methods along the seed value chain.

MLN is caused by the combination of the maize chlorotic mottle virus (MCMV) and any of the viruses belonging to the Potyviridae family.

As part of the project, studies showed that moist soil had higher MCMV virus loads than dry soil. The studies — conducted by Benham Lockhart of University of Minnesota and Peg Redinbaugh, a professor at Ohio State University and Research Leader and Research Plant Molecular Geneticist at USDA — indicated that MCMV can stay active in runoff water, and helped in understanding how the disease is transmitted and how to define management protocols.

“Crop debris may also act as source of MCMV inoculum but for a limited period of up to two months,” said L.M. Suresh, CIMMYT Maize Pathologist, in reference to soil transmission studies conducted by CIMMYT. “A host-free period of two months is, therefore, recommended for effective management of MLN,” he noted.

Rapid and low-cost MLN-causing virus detection methods such as immunostrips and ELISA-based tests were adopted at scale.

“After optimizing the protocols for MLN viruses’ diagnosis suitable for African systems, we transferred these technologies to [national plant protection organizations] and seed companies, not just within the endemic countries but also to the non-endemic countries in southern and west Africa, through intensive trainings,” Prasanna explained. “We created a digital MLN surveillance tool under the Open Data Kit (ODK) app for NPPOs and other stakeholders to effectively carry out MLN surveillance on the ground. The survey information is captured in real time in farmers’ and seed production fields coupled with rapid immunostrips MLN tests,” he remarked.

According to Francis Mwatuni, Project Manager of the MLN Diagnostics and Management project, this proactive and collaborative surveillance network has been an important outcome that helped curb MLN from spreading to non-endemic regions. “In 2016, we only had 625 surveillance points. By 2019, the surveillance points in all the target countries stood at 2,442, which intensified the alertness on MLN presence and how to effectively deal with it,” Mwatuni said. In total, 7,800 surveillance points were covered during the project implementation period.

Over 100 commercial seed firms have also been trained on how to produce MLN-free seed to facilitate trade within the endemic nations and to ensure the disease is not transferred to the non-endemic countries via contaminated seeds.

Sustaining the fight

Researchers continue to work to lessen MLN’s resurgence or new outbreaks. In 2018, incidents in all endemic countries, except Ethiopia, declined sharply. One suggested explanation for the upsurge in Ethiopia, especially in the northwestern region, was reduced use of pesticide for fall armyworm control, as compared to previous years where heavy application of these pesticides also wiped out MLN insect vectors, such as maize thrips and aphids.

At the end of the projects, partners urged for the scale-up of second-generation MLN-tolerant and -resistant varieties. They explained farmers would fully benefit from recent genetic gains of the new improved varieties and its protection against MLN.

“Despite the success registered, MLN is still a major disease requiring constant attention. We cannot rest as we redirect our energies at sustaining and building on the gains made,” said Beatrice Pallangyo, principal agricultural officer in Tanzania’s Ministry of Agriculture, Food Security and Cooperatives.

After the success containing MLN, stakeholders suggested the need to stay alert on other transboundary pests and diseases such as the tar spot complex, which could be a major threat to Africa’s food security in case of an outbreak.

Breaking Ground: Pieter Rutsaert looks to better marketing for faster adoption of climate-smart maize in Africa

Written by Matthew O'Leary on November 22, 2019. Posted in Features.

Ever wondered why farmers prefer a certain maize variety over another? What crop traits different farmers value? How they make their seed selections at the market? Pieter Rutsaert, an expert in markets and value chains with the International Maize and Wheat Improvement Center (CIMMYT), analyzes the important factors that African farmers consider when purchasing maize varieties at agro-dealers and the implications for how the seed industry can better meet farmers’ needs.

Maize is the most important cereal crop in Africa, grown on over 29 million hectares of rainfed farmland and consumed daily by around 50% of the population. However, increasingly erratic weather patterns threaten the performance the maize varieties grown, putting household food security at risk.

“African smallholders typically plant maize seeds they are familiar with, but these varieties often lack the attributes to tolerate harsher weather including droughts, extreme heat or disease stress,” Rutsaert explains.

“Despite the existence of maize varieties bred to stand up to harsher weather, their intrinsic attributes alone are not enough to convince farmers to leave their preferred varieties. These stress-tolerant varieties need to be properly marketed to be competitive and increase their market share.”

With previous experience as a marketing consultant in the food industry, Rutsaert brings unique skills and approaches to CIMMYT’s Stress Tolerant Maize for Africa (STMA) project, to help businesses develop new seed distribution and marketing strategies to get climate-resilient varieties into farmers’ fields.

Market intelligence on climate-smart seed

Rutsaert sees local agro-dealers as a strategic entry point for researchers to gather information on the varying farmer interests and conditions as information about seed demand is revealed at the point of purchase.

Despite large investments to support seed systems in sub-Saharan Africa, including investments to upgrade agro-dealer capacity, there is limited evidence into how women and men take decisions on maize seed purchases to support development initiatives.

“The agro-dealer space is where farmers decide what inputs to buy. In addition to providing farmers access to inputs at competitive prices, front-line agro-dealers offer technical assistance, such as advice on input use and production practices, and short-term credit for input purchases.”

Thus, agro-dealers offer the chance to learn about farmers’ unique conditions and ensure they adopt the right variety. Gathering these insights has the potential to support locally owned small and medium enterprises that produce stress-tolerant varieties, suited for local conditions, says the marketing expert.

Marketing strategies for agro-dealers

Compared to multinational seed companies, local seed businesses are expected to show greater willingness to seek out traditionally underserved segments of the seed market, such as poorer farmers or those located in less-favored production regions. However, local seed producers and retailers generally lack marketing capabilities and have a limited understanding of the costs and benefits of different approaches to market their seed, Rutsaert says.

“Without effective marketing strategies responding to the needs of different clients, farmers will stick to the seeds that they know, even when this might not be the best for their situation,” he continues.

Based on the market information gathered, Rutsaert works with agro-dealers to develop retail strategies, such as targeted marketing materials, provision of in-store seed decision support, and price incentives, to help women and men farmers get the inputs that work best.

Rutsaert says he is committed to use his private sector experience to improve CIMMYT’s understanding of the seed sector and build the capacity of local agro-dealers to distribute climate-resilient maize varieties throughout the African region.

The Stress Tolerant Maize for Africa (STMA) project seeks to develop maize cultivars with tolerance and resistance to multiple stresses for farmers, and support local seed companies to produce seed of these cultivars on a large scale. STMA aims to develop a new generation of over 70 improved stress tolerant maize varieties, and facilitate the production and use of over 54,000 metric tons of certified seed. The STMA project is funded by the Bill & Melinda Gates Foundation and USAID.

A major step toward seed self-sufficiency

Written by Rodrigo Ordóñez on November 22, 2019. Posted in News.

In an historical first, during the 2018-19 season Nepal’s National Maize Research Program (NMRP) coordinated the production of 4 tons of seed of a leading maize hybrid, as part of national efforts to boost maize production and meet rising demand for the crop.

NMRP oversaw production of Rampur Hybrid-10 seed, in collaboration with the Heat Tolerant Maize for Asia (HTMA) project funded by the USAID Feed the Future Initiative and led by the International Maize and Wheat Improvement Center (CIMMYT), the Nepal Seed and Fertilizer (NSAF) project, and local seed companies and farmer cooperatives.

“Producing hybrid maize seed and getting quality seed to farmers at a reasonable price involves multiple stakeholders,” said P.H. Zaidi, CIMMYT maize physiologist and HTMA leader. “NMRP is pursuing a public-private partnership model to have key value chain components in place for this. The success this year may encourage other companies to switch from producing seed of open-pollinated maize varieties to that of hybrids, which are higher yielding.”

Lumbini Seed Company alone harvested 2.5 tons of hybrid seed from one hectare of land, helping to debunk the common myth that production of maize hybrid seed was impossible in Nepal, according to Zaidi.

“Lumbini did good groundwork to identify a suitable season and site for seed production, helping them to achieve a good hybrid seed harvest in their first-ever attempt,” said Zaidi. “The NMRP and other seed companies contributed valuable knowledge and advice to improve and scale up hybrid maize seed production.”

Maize is a critical food, feed and fodder crop in Nepal, providing nearly 20% of people’s food energy and accounting for around 33% of all cereal production in the high hills regions, 39% in the mid-hills region, and 9% in the Terai. Over two-thirds of hill-region maize is eaten directly as food on farm homesteads, whereas 80% of maize in the Terai and neighboring regions is used as feed.

Demand for feed maize is skyrocketing, as consumers switch from starch-based foods to animal protein and dairy products. Current national maize production satisfies less than a third of feed industry demand, requiring maize grain imports that reached 4.8 million tons in 2017-18.

Against this backdrop, many smallholder farmers still grow local or open-pollinated maize varieties, which are usually low yielding.

Based in Rampur, Chitwan, and established in 1972, the NMRP has developed and released 29 open-pollinated and 5 hybrid maize varieties, including Rampur Hybrid-10, with technical support from CIMMYT. Multinational companies have registered 54 other maize hybrids for marketing in Nepal. To date, nearly all hybrid seed is imported.

Other partners in efforts to produce hybrid seed in Nepal include the farmer cooperatives Namuna Sahakari and Jhapa, as well as the companies SEAN Seed in Kathmandu and Unique Seed Company in Dhangadi. NMRP is also developing and registering new high-yielding hybrids. Some nucleus and breeders seed is being produced by the Agricultural Research Station (ARS) and Regional Agricultural Research Station (RARS) of the Nepal Agricultural Research Council (NARC).

The NMRP and participating seed companies expect to meet half of Nepal’s hybrid maize seed requirements through such domestic seed production within five years, with the objective to achieve complete seed self-sufficiency later on.

Stress-resilient maize, a big relief for Indian farmers

Small-scale maize farmers beset by erratic rainfall in the state of Karnataka, India, who adopted a new, drought- and heat-tolerant maize hybrid are harvesting nearly 1 ton more of grain per hectare than neighboring farmers who sow other maize varieties.

The climate-resilient hybrid RCRMH2 was developed in 2015 by the University of Agriculture Sciences, Raichur (UAS-R), Karnataka, as part of the Heat Tolerant Maize for Asia (HTMA) project. It was marketed in 2018 under the commercial name MRM4070 by Maharashtra Hybrid Seeds Company (Mahyco) in hot and dry areas of Karnataka, where crops are watered exclusively by rainfall.

“This hybrid is made for our stress-prone areas, as it gives guaranteed yields in a bad year and is inferior to none under good rainfall conditions,” said Hanumanthappa, a farmer and adopter of the variety in Gadag District. “In bad years, it can not only feed my family but also my cattle,” he added, referring to the hybrid’s “stay-green” trait, which allows use of the leaves and stems as green fodder for livestock, after harvesting the cobs.

Droughts and high temperatures are a recurring problem in Karnataka, but suitable maize varieties to protect yields and income loss in the state’s risk-prone agroecologies had been lacking.

Mahyco marketed some 60 tons of hybrid seed of MRM4070 in Karnataka in 2018 and, encouraged by the overwhelming response from farmers, increased the seed offering to 140 tons — enough to sow about 7,000 hectares.

A 2018-19 farmer survey in the contrasting Gadag District — with poor rainfall — and Dharwad District — good rainfall — found that farmers in Gadag who grew MRM4070 harvested 0.96 tons more grain and earned $190 additional income per hectare than neighbors who did not adopt the hybrid. In Dharwad under optimal rainfall, MRM4070 performed on a par with other commercial hybrids.

In addition to providing superior yields under stress, MRM4070 had larger kernels than other hybrids under drought conditions, bringing a better price for farmers who sell their grain.

Led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with national maize programs, agriculture universities, and seed companies, and with funding from the United State Agency for International Development (USAID) Feed the Future Initiative, HTMA was launched in 2012 to develop stress-resilient maize hybrids for the variable weather conditions and heat and drought extremes of Bangladesh, India, Nepal and Pakistan.

Seeds of hope

Written by Rodrigo Ordóñez on November 15, 2019. Posted in Features. 1 Comment on Seeds of hope

Seed of drought-tolerant maize developed through long-running global and local partnerships in Africa is improving nutrition and food security in northern Uganda, a region beset by conflicts and unpredictable rainfall.

The International Maize and Wheat Improvement Center (CIMMYT) has been working with Uganda’s National Agricultural Research Organization (NARO) and local seed companies to develop and disseminate maize seed of improved stress-tolerant varieties. Under the Drought Tolerant Maize for Africa (DTMA) and the Stress Tolerant Maize for Africa (STMA) projects, farmers are now using varieties such as the UH5051 hybrid, known locally as Gagawala, meaning “get rich.”

For two decades, most of the population in northern Uganda has lived in internally displaced people’s camps and depended on food aid and other relief emergencies for their livelihoods due to the insurgency by the Lord’s Resistance Army (LRA).

Gulu, one of the affected districts, has been on a path to recovery for the past few years. With the prevailing peace, Geoffrey Ochieng’ and his wife can now safely till their 4.5 acres of land to grow maize and other staples. They are able to feed their family and sell produce to meet other household needs.

However, farmers in this region, bordering South Sudan, are facing more erratic rains and the uncertain onset of rainfall. Thanks to new drought-tolerant and disease-resistant maize varieties, the Ochieng’ family can adapt to this variable climate and secure a good maize harvest even in unreliable seasons.

Tolerance is key

“The popularity of this drought-tolerant variety among the farmers has been growing thanks to its good yield and reliability even with poor rains and its resistance to common foliar diseases like northern corn leaf blight and gray leaf spot, plus good resistance to the maize streak virus,” explained Daniel Bomet, a NARO maize breeder. “Maturing in slightly over four months, Gagawala can produce two to three maize cobs, which appeals to farmers.”

Ochieng’ has been planting UH5051 maize since 2015. Before adopting the new hybrid, Ochieng’ was growing Longe 5, a popular open-pollinated variety that is less productive and not very disease-resistant.

“What I like about UH5051 is that even with low moisture stress, it will grow and I will harvest something,” Ochieng’ said. Under optimal conditions, he harvests about 1.2 metric tons of maize grain on one acre of UH5051 hybrid.

With the old Longe 5 variety, he would only harvest 700 kg. “If the rains were delayed or it didn’t rain a lot, I would be lucky to get 400 kg per acre with the Longe 5, while I get twice as much with the hybrid,” Ochieng’ explained.

Thanks to this tolerant maize variety, he can pay his children’s school fees and provide some surplus grain to his relatives.

Out with the old, in with the new

“One key strategy to improve our farmers’ livelihoods in northern Uganda is to gradually replace old varieties with new varieties that can better cope with the changing climate and problematic pests and diseases,” said Godfrey Asea, the director of the National Crops Resources Research Institute (NaCRRI) at NARO. “Longe 5 for instance, has been marketed for over 14 years. It has done its part and it needs to give way to new improved varieties like UH5051.”

The Gulu-based company Equator Seeds has been at the core of the agricultural transformation in northern Uganda. From 70 metrics tons of seed produced when it started operations in 2012, the company reached an annual capacity of about 7,000 to 10,000 metric tons of certified seed of different crops in 2018. Working with dedicated out-growers such as Anthony Okello, who has a 40-acre piece of land, and 51 farmer cooperatives comprising smallholder farmers, Equator Seeds produces seed of open-pollinated hybrid maize and other crops, which reaches farmers through a network of 380 agro-dealers.

“80% of farmers in northern Uganda still use farm-saved or recycled seed, which we consider to be our biggest competitor,” Tonny Okello, CEO of Equator Seeds remarked. “Currently, about 60% of our sales are in maize seed. This share should increase to 70% by 2021. We plan to recruit more agro-dealers, establish more demonstration farms, mostly for the hybrids, to encourage more farmers to adopt our high yielding resilient varieties.”

The two-decade unrest discouraged seed companies from venturing into northern Uganda but now they see its huge potential. “We have received tremendous support from the government, non-governmental organizations, UN and humanitarian agencies for buying seed from us and distributing it to farmers in northern Uganda and South Sudan, to aid their recovery,” Okello said.

Social impact

The Ugandan seed sector is dynamic thanks to efficient public-private partnerships. While NARO develops and tests new parental lines and hybrids in their research facilities, they have now ventured into seed production and processing at their 2,000-acre Kigumba Farm in western Uganda through NARO Holdings, their commercial arm.

“Because the demand for improved seed is not always met, NARO Holdings started producing certified seed, but the major focus is on production of early generation seed, which is often a bottleneck for the seed sector,” Asea said.

Another innovative collaboration has been to work with the Uganda Prisons Service (UPS) establishments to produce maize seed. “When we started this collaboration with UPS, we knew they had some comparative advantages such as vast farmland, ready labor, mechanization equipment and good isolation, which are important for high-quality hybrid maize seed production,” Asea explained. The UPS facility in Lugore, Gulu, which has 978 hectares of land, produces foundation seed of UH5051.

“Prisons offer a big potential to support the growing seed industry,” he said. “Together with CIMMYT, we should build further the capacity of UPS to produce foundation and certified seeds. It provides much-needed income for the institutions. The inmates, in addition to being remunerated for farm labor, are engaged in positive outdoor impactful activities. This skill is helpful for their future reintegration in the society.”

Fight against fall armyworm in Asia benefits from experience in other regions

Written by Rodrigo Ordóñez on October 31, 2019. Posted in Features. 2 Comments on Fight against fall armyworm in Asia benefits from experience in other regions

When the destructive fall armyworm arrived in Asia in the summer of 2018, scientists were not taken by surprise. They had been anticipating its arrival on the continent as the next stage of its aggressive eastward journey, driven by changing climatic conditions and international trade routes. The pest, native to North and South America, had invaded and spread throughout most of sub-Saharan Africa within two years, severely damaging billions of dollars of maize crops and threatening food security for millions of people. Asian countries would have to mobilize quickly to cope with this new threat.

After reaching India in 2018, the pest spread to other parts of Asia, including Bangladesh, mainland China, Indonesia, Laos, Myanmar, Nepal, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.

Fall armyworm is a major threat to Asia’s maize farmers, many of whom derive a crucial source of household income by selling maize as feed grain for the growing poultry sector. What is not sold is paramount for subsistence and daily nutrition in communities in the hills of Nepal, in the tribal regions of India, in the mountainous provinces of southern China, and in parts of Indonesia and the Philippines.

The pest is here to stay

Fall armyworm cannot be eradicated — once it has arrived in an agro-ecosystem, farmers must learn how to cope with it. Farmers in the Americas have lived with this pest for the last two hundred years, but their tools and management techniques cannot be simply applied in Africa or Asia. Solutions need to be tailored to specific countries and local contexts, to account for the vast differences in local ecologies, practices, policies and other conditions.

Timothy J. Krupnik and B.M. Prasanna are two of the scientists responding to fall armyworm in Asia. Both are with the International Maize and Wheat Improvement Center (CIMMYT). As a long-established organization with global presence, CIMMYT had decades of experience managing fall armyworm in its native lands before the global spread started. These scientists see the enormous threat to maize crops in Asia, and the negative impact it could have on the income and wellbeing of smallholders and their families, but they also point to opportunities to develop, validate and deploy effective solutions.

In South Asia, farmers have developed intensive agricultural techniques to produce food for rapidly growing populations, meaning agricultural inputs such as seeds, fertilizer and pesticides are more readily available than in much of Africa. The private sector is generally good at getting solutions to farmers, who are often willing and able to adopt new ways of farming. “The private sector in South Asia is in a good position to exchange and transfer technologies across the region,” explains Prasanna, who leads CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.

The accessibility of pesticides also has its risks, says Krupnik, a senior scientist based in Bangladesh. “If used incorrectly, pesticides can be unsafe, environmentally damaging and even ineffective,” he says. Krupnik’s team is currently engaging with pesticide companies in Bangladesh, helping them develop an evidence-based response to fall armyworm. “We want to encourage effective, environmentally safer solutions such as integrated pest management that cause least harm to people and ecosystems,” he explained.

A global effort

The global nature of the challenge may have a silver lining. “Over the last three years, we have learned important lessons on fall armyworm management in Africa, including what technologies work and why,” says Prasanna. “With the pest now a global problem, there is great potential for cooperation among affected countries, especially between Africa and Asia.”

Researchers emphasize that a collective effort is needed to respond to the fall armyworm in Asia. CIMMYT is working with partners around the world to help leverage and share expertise and technologies across borders.

China has as much acreage of maize as the whole African continent, and has tremendous institutional expertise and capacity to deal with new challenges, explains Prasanna. His team is in discussions with Chinese researchers to share knowledge and solutions across Asia.

Bangladesh and Nepal are among the countries seeking linkages with international experts and researchers in other countries.

In Africa, CIMMYT was part of a global coalition of scientists and governments who joined forces in 2017 to tackle the fall armyworm threat and develop scientific solutions. The researchers want to see this approach expand into Asia, supported by the donor community.

As the pest continues its relentless expansion in the region, extensive work is ahead for both research and development institutions. Researchers need to identify and promote best management practices. Technologies will have to be environmentally sustainable, durable and inclusive, says Prasanna.

Joining hands

“To achieve this, we need a multidisciplinary team including breeders, pest management experts, seed specialists, agronomists and socioeconomists, who can share science-based evidence with development partners, governments and farmers,” Prasanna says.

CIMMYT researchers are on the path towards developing improved maize varieties with native genetic resistance to fall armyworm. They are also engaging with farming communities to make sure other integrated pest management solutions are available.

In addition to developing agronomic practices and technologies, scientists are reaching out to farming communities with the right messages, Krupnik explains. “As well as being technical experts, our scientists are embedded in the countries where we work. We’ve lived here for a long time, and understand how to engage with local partners,” he says.

Cross-border collaboration and knowledge transfer is already happening. Partners in Laos enthusiastically adapted fall armyworm informational materials from Bangladesh for local dissemination. Krupnik and his team have also collaborated on a video with guidance on how to identify and scout for fall armyworm in a field, developed by Scientific Animations without Borders.

Fall armyworm will continue its spread across Asia, and researchers will have many questions to answer, such as how fall armyworm interacts with very diverse Asian agro-ecosystems, the pest population dynamics, and measuring the economic impacts of interventions. Solutions need to be developed, validated and deployed for the short, medium and long term. Krupnik and Prasanna hope that international cooperation can support these crucial research-for-development activities.

“Fall armyworm is here to stay. We are running a marathon and not a 100-meter sprint,” proclaimed Prasanna. “Let’s work collectively and strategically so that the farmer is the ultimate winner.”

Climate, nutrition and security challenges require global food system transformation

Written by Mary Donovan on October 25, 2019. Posted in Features.

“Can we sustainably feed the nine to ten billion people in our planet in 30 years?” asked Kenneth M. Quinn, president of the World Food Prize Foundation. “This question becomes even more challenging with two current game changers: conflict and climate change.”

Food and agriculture experts met in Des Moines, Iowa, to discuss these issues at the Borlaug Dialogue and awarding of the 2019 World Food Prize.

The focus has shifted over the last few years from food to food systems, now including health and nutrition. “We need an integrated agri-food systems approach for food security, nutrition, nature conservation and human security,” said Bram Govaerts, director of the Integrated Development program at the International Maize and Wheat Improvement Center (CIMMYT).

Speakers agreed that to meet the current challenges of nutrition and climate change, we need a transformation of the global food system. “We have something very positive — this narrative of food system transformation,” said Ruben Echeverría, Director General of the International Center for Tropical Agriculture (CIAT).

In the discussions, speakers highlighted several areas that must be taken into consideration in this transformation.

Food security for peace and development

The theme of this year’s Borlaug Dialogue was “Pax Agricultura: Peace through agriculture.” Panels addressed the interconnected issues of food security, conflict and development.

In the keynote address, USAID Administrator Mark Green issued a call to action and challenged participants “to take on the food and economic insecurity issues that are emerging from this era’s unprecedented levels of displacement and forced migration.” Ambassadors, ministers and development experts gave examples of the interdependence of agriculture and peace, how droughts and floods could create conflict in a country, and how peace can be rebuilt through agriculture.

“Agriculture could root out the insurgency better than anything we did,” said Quinn about the Khmer Rouge surrender in Cambodia, where he served as an ambassador.

In the 1994 genocide in Rwanda, more than 1 million people died in 100 days. Geraldine Mukeshimana, Rwanda’s minister of Agriculture and Animal Resources, explained that in the country’s rebuilding process, all policies centered on agriculture.

“Almost no country has come out of poverty without an agricultural transformation,” said Rodger Voorhies, president of Global Growth and Opportunity at the Bill & Melinda Gates Foundation, in a fireside chat with 2009 World Food Prize Laureate Gebisa Ejera.

Agriculture is vital because without food, we cannot build institutions, processes or economies. “You cannot talk about human rights if you don’t have any food in your stomach,” said Chanthol Sun, Cambodia’s minister of Public Works and Transportation.

Josette Sheeran, president and CEO of Asia Society, echoed this thought, “Nothing is more important to human stability than access to food.”

In a luncheon keynote, Víctor M. Villalobos, Mexico’s Secretary of Agriculture and Rural Development, spoke about CIMMYT, the MasAgro project, and the need to improve food systems and agriculture to fight violence and forced migration. “Agriculture, prosperity and peace are inextricably linked together.”

How to make technological innovations work

Innovations and technology can support a global food system transformation and help to achieve the Sustainable Development Goals.

In a panel on food security in the next decade, speakers shared the agricultural technologies they are excited about: data, gene editing, synthetic biology, data science and precision farming.

Josephine Okot, managing director of Victoria Seeds Ltd said, “We must have mechanization.” She described the fact that Ugandan women farmers still rely on hand tools as a “disgrace to humanity.”

The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) organized a session where panelists discussed how to realize a transformation in food systems through next generation technologies, highlighting the role regulatory frameworks and policies play in the adoption of new technologies.

Making innovations work is about more than developing the product. “It takes a lot more than just a good seed to get a farmer to use it,” said 2019 World Food Prize Laureate Simon Groot. “It includes good distribution, good marketing, good training, etcetera.”

Technology adoption requires a human emphasis and cultural element in addition to technology development.

Breeding demand-driven crops for all

“The real enemy of farmers is lousy seeds,” said Simon Groot in his speech after receiving the World Food Prize.

CGIAR took the occasion of the World Food Prize to launch a new initiative, Crops to End Hunger. “We are looking for big solutions at CGIAR. Crops to End Hunger is one of them,” said CIMMYT Director General Martin Kropff. This program aims to meet the food, nutrition and income needs of producers and consumers, respond to market demands and increase resilience to challenges of the climate crisis.

“CGIAR released 417 new varieties last year. However, we can do more. Crops to End Hunger will rapidly excel breeding cycles,” said Elwyn Grainger-Jones, CGIAR Executive Director.

Felister Makini, deputy director general for Crops at Kenya Agricultural & Livestock Research Organization (KALRO), explained that focusing on the end users is what will have real impact. “It is important to develop technologies that are demand-driven so that farmers want to grow them and consumers want to buy and eat them.”

In a session to unpack the Crops to End Hunger initiative hosted by Corteva Agriscience and CGIAR, Marco Ferroni, Chair of the CGIAR System Management Board, said that CGIAR is shifting toward a more demand-driven agenda for plant breeding, where markets dictate what the research priorities should be.

“We must consider the human aspect in breeding,” said Michael Quinn, Director of the CGIAR Excellence in Breeding Platform (EiB). “This is where success will really come.”

Panelists discussed gender-conscious breeding, or taking both women and men’s desired traits into account.

The theme of gender was also emphasized by 2019 Norman Borlaug Field Award winner Hale Ann Tufan. She asked the Dialogue attendees to question gender biases and “not only to ‘take it to the farmer’ but take it to all farmers.”

Pulses, cobs and a healthy soil prove the success of a rural innovator

Written by Shiela Chikulo on October 14, 2019. Posted in Features. 2 Comments on Pulses, cobs and a healthy soil prove the success of a rural innovator

Mary Twaya is an exemplary farmer in Lemu, a rural drought-prone community in southern Malawi, near Lake Malombe. On her one-hectare farm she grows cotton, maize, and legumes like groundnut and cowpea, which she just picked from her fields. Since agriculture is Twaya’s sole livelihood, it is important for her to get good harvests, so she can support her three children and her elderly mother. She is the only breadwinner since her husband left to sell coffee in the city and never returned.

Agriculture is critically important to the economy and social fabric of Malawi, one of the poorest countries in the World. Up to 84% of Malawian households own or cultivate land. Yet, gender disparities mean that farmland managed by women are on average 25% less productive than men. Constraints include limited access to inputs and opportunities for capacity building in farming.

Climate change may worsen this gender gap. Research from the International Maize and Wheat Improvement Center (CIMMYT) shows that there are multidimensional benefits for women farmers to switch to climate-smart agriculture practices, such as planting drought-tolerant maize varieties and conservation agriculture with no tillage, soil cover and crop diversification.

Twaya was part of a CIMMYT project that brought climate-smart agriculture practices to smallholder farmers in Malawi, Zambia and Zimbabwe.

She was enthusiastic about adopting climate-smart agriculture practices and conservation agriculture strategies in her plot. “I have always considered myself an active farmer, and when my husband left, I continued in the project around 2007 as part of the six lead ‘mother farmers’ with about 30 more ‘baby farmers’ learning through our field trials,” Twaya explained.

“We worked in Lemu since 2007 with Patrick Stanford, a very active and dedicated extension officer who introduced conservation agriculture to the village,” said CIMMYT agronomist Christian Thierfelder. “Farmers highlighted declining yields. The Lemu community was keen to transform their farming system, from conventional ridge tillage to more sustainable and climate-adapted cropping systems.” This was an ideal breeding ground for new ideas and the development of climate-smart solutions, according to Thierfelder.

Mulching, spacing and legume diversification

Showing her demonstration plot, which covers a third of her farm, Twaya highlights some of the climate-smart practices she adopted.

“Mulching was an entirely new concept to me. I noticed that it helps with moisture retention allowing my crops to survive for longer during the periods of dry spells. Compared to the crops without mulching, one could easily tell the difference in the health of the crop.”

“Thanks to mulching and no tillage, a beneficial soil structure is developed over time that enables more sustained water infiltration into the soil’’, explained Thierfelder. “Another advantage of mulching is that it controls the presence of weeds because the mulch smothers weeds unlike in conventional systems where the soil is bare.”

Research shows that conservation agriculture practices like mulching, combined with direct seeding and improved weed control practices, can reduce an average of 25-45 labor days per hectare for women and children in manual farming systems in eastern Zambia and Malawi. This time could be used more productively at the market, at home or in other income-generating activities.

After 12 years of practicing conservation agriculture, Twaya confirms that she does not spend too much time in the field because she just uproots the weeds with no need for using a hoe. This makes the weeding task less laborious and allows her to spend her time on other chores such as fetching water, washing laundry or cleaning her homestead. “I have time to also go to the village banking and loan savings club to meet with others”.

Adopting optimum plant density, instead of throwing in three seeds in each planting hole was another transformational change. The “Sasakawa spacing” — where maize seeds are planted 25 centimeters apart in rows spaced every 75 centimeters — saves seed and boosts yields, as each plant receives adequate fertilizer, light and water without competing with the other seeds. This practice was introduced in Malawi in the year 2000 by Sasakawa Global.

Twaya pays more attention to the benefits of planting nitrogen-fixing crops alongside her maize, as she learned that “through crop rotation, legumes like pigeon pea improve the nutrition of my soil.” In the past she threw pigeon pea seeds loosely over her maize field and let it grow without any order, but now she practices a “double-up legume system,” where groundnut and pigeon pea are cropped at the same time. Pigeon peas develop slowly, so they can grow for three months without competition after groundnut is harvested. This system was introduced by the Africa RISING project, funded by USAID.

A mother farmer shows the way

Switching to climate-smart agriculture requires a long-term commitment and knowledge. Some farmers may resist to the changes because they initially find it new and tedious but, like Twaya observed, “it may be because they have not given themselves enough time to see the long-term benefits of some of these practices.”

With all these innovations — introduced in her farm over the years with the support of CIMMYT and the Ministry of Agriculture, Irrigation and Water Development of Malawi — Twaya reaped important economic and social benefits.

When Twaya rotates maize and pigeon pea, the maize stalks are healthy and the cobs are big, giving her higher yields. Passing-by neighbors will often exclaim ‘‘Is this your maize?’’ because they can tell it looks much more vigorous and healthier than what they see in other fields.

For the last season, Twaya harvested 15 bags of 50kg of maize from her demo plot, the equivalent of five tons per hectare. In addition to her pigeon pea and groundnut crops, she was able to feed her family well and earned enough to renovate her family home this year.

This new way of managing her fields has gained Twaya more respect and has improved her status in the community.

Through surplus sales of maize grain, pigeon pea and groundnuts over the past 12 years, Mary has generated enough income to build a new home. Nearing completion, she has purchased iron sheets for roofing this house by the end of 2019. (Photo: Shiela Chikulo/CIMMYT)

A fresh look at the genes behind grain weight in spring bread wheat

Written by Marcia MacNeil on October 9, 2019. Posted in News.

To meet the demand for wheat from a rising and quickly urbanizing population, wheat yields in farmers’ fields must increase by an estimated 1.5% each year through 2030.

Of all the factors that influence yield, grain weight is the trait that is most stable and heritable for use in breeding improved wheat varieties. Breeders measure this by thousand grain weight (TGW).

Over the years, molecular scientists have made efforts to identify genes related to increased TGW, in order to speed up breeding through marker-assisted selection (MAS). Using MAS, breeders can select parents that contain genes related to the traits they are looking for, increasing the likelihood they will be passed on and incorporated in a new variety.

There have been some limited successes in these efforts: in the past years, a few genes related to increased TGW have been cloned, and a set of genetic markers have been determined to be used for MAS. However, the effects of most of these candidate genes have not yet been validated in diverse sets of wheat germplasm throughout the world that represent the full range of global wheat growing environments.

A group of wheat geneticists and molecular breeders from the International Maize and Wheat Improvement Center (CIMMYT) has recently conducted a thorough study to confirm the effects of the favorable alleles reported for these genes on TGW in CIMMYT wheat, and to identify new genetic determinants of this desired trait.

They found some good news and some bad news.

First, the good news: focusing on more than 4,000 lines of CIMMYT wheat germplasm they found 15 haplotype blocks significantly associated with TGW. Four haplotype blocks associated with TGW were also associated with grain yield — a grand prize for breeders, because in general the positive association of grain yield with TGW is less profound and sometimes even negative. However, of the 14 genes that had been previously reported to increase TGW, only one in CIMMYT’s 2015-2016 Elite Yield Trial and two in Wheat Associative Mapping Initiative panel were shown to have significant TGW associations.

The scientists also found that the alleles — pairs of genes on a chromosome that determine heredity — that were supposedly favorable to TGW actually decreased it. These candidate genes also appear to vary in their TGW effects with genetic background and/or environment.

Thus, these findings also provide a foundation for more detailed investigations, opening the door for more studies on the genetic background dependence and environment sensitivity of the known candidate genes for TGW.

“Our findings indicate that it will be challenging to use MAS based on these existing markers across individual breeding programs,” said Deepmala Sehgal, CIMMYT wheat geneticist and the primary author of the study.

However, efforts to identify new genetic determinants of TGW were promising. The authors’ study of CIMMYT germplasm found one locus on chromosome 6A that showed increases of up to 2.60 grams in TGW and up to 258 kilograms per hectare in grain yield.

This discovery expands opportunities for developing diagnostic markers to assist in multi-gene pyramiding — a process that can derive new and complementary allele combinations for enhanced wheat TGW and grain yield.

Most of all, the study highlights the strong need for better and more validation of the genes related to this and other traits, so that breeders can be sure they are using material that is confirmed to increase wheat grain weight and genetic yield.

“Our findings are very promising for future efforts to efficiently develop more productive wheat in both grain weight and grain yield,” said Sehgal. “This ultimately means more bread on household tables throughout the world.”

New publications: Do market shocks generate gender-differentiated impacts?

Written by Emma Orchardson on September 24, 2019. Posted in Publications.

Female-headed households are likely to experience higher welfare losses due to commodity price hikes than their male-headed counterparts, as they tend to spend a larger percentage of their income on food items. However, the full extent of this impact of market has not been widely examined in the empirical literature.

Applying the difference-in-difference estimation procedure to data collected from more than 22,000 households in Bangladesh in 2005 and 2010, researchers at the International Maize and Wheat Improvement Center (CIMMYT) set out to examine the gender-differentiated impacts of the commodity price hikes during the food price crisis of 2008 on food and non-food consumption behavior based on the sex of the household head.

They found that, in general, the commodity price hikes had more adversely affected female-headed households, which reduced their expenditure on food and non-food items such as cereals and education at a greater rate than their male-headed counterparts did.

However, their study also reveals that the welfare impacts on these households varied greatly depending on socio-economic conditions. Results showed that households headed by women who were relatively better educated, who owned larger pieces of land and received remittances were buffered to a certain extent and their expenditure was affected less.

Understanding these buffering factors, the authors argue, is crucial when designing policy interventions in developing countries. The study provides a number of recommendations for government and international donor agencies to help female-headed households better cope with market shocks. For example, they could improve the reach of general education, increase women’s access to land and agricultural assets and remove barriers to the in-flow of remittances for female-headed households. Extending the reach of social protection and microcredit programs could further complement market shock buffering capacity, as could providing targeted capital.

Read more results and recommendations in the study, “Do market shocks generate gender-differentiated impacts? Policy implications from a quasi-natural experiment in Bangladesh” in Women’s Studies International Forum, Volume 76, September–October 2019.

This study was made possible through the support provided by the United States Agency for International Development (USAID) to the Cereal Systems Initiative for South Asia – Mechanization and Irrigation (CSISA-MI) project, and the Bill & Melinda Gates Foundation to the CSISA Phase II project.

Large-scale genomics will improve the yield, climate-resilience, and quality of bread wheat, new study shows

Written by Mike Listman on September 23, 2019. Posted in Press releases. 2 Comments on Large-scale genomics will improve the yield, climate-resilience, and quality of bread wheat, new study shows

Using the full wheat genome map published in 2018, combined with data from field testing of wheat breeding lines in multiple countries, an international team of scientists has identified significant new chromosomal regions for wheat yield and disease resistance and created a freely-available collection of genetic information and markers for more than 40,000 wheat lines.

Reported today in Nature Genetics, the results will speed up global efforts to breed more productive and climate-resilient varieties of bread wheat, a critical crop for world food security that is under threat from rising temperatures, rapidly-evolving fungal pathogens, and more frequent droughts, according to Philomin Juliana, wheat scientist at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new study.

“This work directly connects the wheat genome reference map with wheat lines and extensive field data from CIMMYT’s global wheat breeding network,” said Juliana. “That network in turn links to over 200 breeding programs and research centers worldwide and contributes to yield and other key traits in varieties sown on nearly half the world’s wheat lands.”

The staple food for more than 2.5 billion people, wheat provides 20% of human dietary calories and protein worldwide and is critical for the nutrition and food security of hundreds of millions of poor persons in regions such as North Africa and South Asia.

“Farmers and societies today face new challenges to feed rising and rapidly-urbanizing populations, and wheat epitomizes the issues,” said Ravi Singh, CIMMYT wheat breeder and corresponding author of the study. “Higher temperatures are holding back yields in major wheat-growing areas, extreme weather events are common, crop diseases are spreading and becoming more virulent, and soil and water are being depleted.”

Juliana said the study results help pave the way to apply genomic selection, an approach that has transformed dairy cow husbandry, for more efficient wheat breeding.

“Molecular markers are getting cheaper to use; meanwhile, it’s very costly to do field testing and selection involving many thousands of wheat plants over successive generations,” Juliana said. “Genome-wide marker-based selection can help breeders to precisely identify good lines in early breeding generations and to test plantlets in greenhouses, thereby complementing and streamlining field testing.”

The new study found that genomic selection could be particularly effective in breeding for wheat end-use quality and for resistance to stem rust disease, whose causal pathogen has been evolving and spreading in the form of highly-virulent new races.

The new study also documents the effectiveness of the global public breeding efforts by CIMMYT and partners, showing that improved wheat varieties from this work have accumulated multiple gene variants that favor higher yields, according to Hans-Joachim Braun, director of CIMMYT’s global wheat program.

“This international collaboration, which is the world’s largest publicly-funded wheat breeding program, benefits farmers worldwide and offers high-quality wheat lines that are released directly to farmers in countries, such as Afghanistan, that are unable to run a full-fledged wheat breeding program,” Braun explained.

The study results are expected to support future gene discovery, molecular breeding, and gene editing in wheat, Braun said.

Together with more resource-efficient cropping systems, high-yielding and climate-resilient wheat varieties will constitute a key component of the sustainable intensification of food production described in Strategy 3 of the recent EAT-Lancet Commission recommendations to transform the global food system. Large-scale genomics will play a key role in developing these varieties and staying ahead of climate- and disease-related threats to food security.

Funders of this work include USAID’s Feed the Future Innovation Lab for Applied Wheat Genomics. Contributing to the research described are research teams engaged in wheat improvement at CIMMYT, and the lab of Jesse Poland, Associate Professor at Kansas State University and Director of the USAID Applied Wheat Genomics Innovation Lab.

Collaborative product profiling captures farmers’ demand for greater impact

Written by Jérôme Bossuet on September 17, 2019. Posted in Features.

The International Maize and Wheat Improvement Center (CIMMYT) organized its first ever Maize Product Profile-based Breeding and Varietal Turnover workshop for eastern Africa in Nairobi, on August 29 and 30, 2019. The workshop, funded by USAID, was attended by maize breeders from national research institutes in Kenya, Uganda, Tanzania, Rwanda, Ethiopia and South Sudan, and by several partner seed companies including Seedco, Kenya Seeds, Western Seeds, Naseco and Meru Agro.

A product profile is defined as a list of “must-have” maize characteristics or traits that are the unique selling points for the target beneficiaries who are looking for these qualities. The breeders also consider additional traits in their breeding strategy, “value-added” or desirable traits that could be future unique selling points.

“A product profile is not a secret sauce” nor a checkbox to tick, explained Georges Kotch, a renowned expert in the seed industry and lead for Module 1 of the Excellence in Breeding (EiB) platform on product profiling. A product profile is a blueprint to help maize breeding programs ensure their new varieties released respond to a true need with a clear comparative advantage for seed companies and ultimately for maize farmers. This demand-driven process “starts with the end in mind” by understanding what the customers want. The end goal is to replace leading old varieties on the market with better ones that will improve farmers’ livelihoods, for example, with greater climate resilience and productivity.

Steering the breeding program through “healthy tensions”

Breeders may have had the tendency to focus on optimum yield for a certain agroecology, yet their priority traits may not reflect exactly the market or what farmers want. In addition to good yield, drought or disease resistance, grain color, taste, nutritional value, and appearance of plants and cobs are important in farmers’ choice of seed. Socio-economic research tools like participatory varietal selection (PVS) or willingness-to-pay experiments help us weigh the importance of each trait to trigger adoption.

There may be tensions between farmers’ needs, what suits seed companies like the seed reproducibility ratio, and what is possible and cost-effective from a breeder’s perspective. CIMMYT does not only look through the lens of economic return. The social impact new varieties could have is also considered, for example developing provitamin A or quality protein maize (QPM) as a solution to combat malnutrition even if there is not a major demand from private seed companies in Africa for nutritious maize.

Qualities valued by some actors may be overlooked by others. For example, some maize varieties have leafy ears with deceptively small cobs, which may protect the grain against pests but could be rejected by farmers.

It is important to have a wide array of expertise from breeding, market research and socio-economic analysis so that the different trait choices are weighed according to different lenses and a clear strategy for varietal turnover is defined.

High performing hybrids may not be enough for large-scale adoption

In southern Africa, climate experts warn that farmers could face drought every three years. CIMMYT has rightly prioritized drought tolerance (DT) over the last decade under the Stress Tolerant Maize for Africa initiative. Recently developed DT maize hybrids often outperform the popular varieties on the market, yet the varietal turnover has been slow in some regions. Farmers’ perceptions of what is a good maize may influence the success or rejection of a new variety. The risk for farmers and seed companies to try out a new variety is an important factor in adoption as well.

An appropriate seed marketing strategy is key, often seen only as the responsibility of private seed companies, but should be considered by public research as well.

CIMMYT has been selecting maize that can withstand drought during the critical phase just before and during the flowering stage, when the silks of the future cobs form. Even if rains stop at this stage, farmers growing DT maize will harvest some decent grain. If a long dry spell occurs just after planting, the crop will fail regardless of drought-tolerant breeding efforts. Farmers may then reject DT maize after such failure if the messaging is not clear.

Product profiling is a collaborative process, not an imposing one

Redefining the breeding strategy through product profiling is not set in stone. Kotch recommends annual review as a vehicle for constant improvement. B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize (MAIZE) explained that the product profiles could vary among various partners, as each partner looks at their own comparative advantage to reach success.

It is important to have everyone from the maize seed value chain on board to succeed. Regina Tende, maize breeder and entomologist at the Kenya Agricultural & Livestock Research Organization (KALRO), warned that regulatory bodies who review and authorize new varieties to reach the market must be integrated in the discussion “as their interest, primarily yield, may not be the final requirement for the target market.”

Seed systems specialists are also crucial to operationalize a successful breeding and delivery strategy, to address the different scaling bottlenecks and identify “the market changer.”

According to Kotch, CGIAR and national research organizations should avoid developing products too similar to the popular varieties on the market. Adoption occurs when something very different, for example new resistance to the devastating maize lethal necrosis, gives an innovation edge to seed companies. In Ethiopia, the replacement of an old popular variety BH660 by climate resilient BH661 was successful for various reasons including superior hybrid seed production with grey leaf spot resistance built in the seed parent population.

This demand-driven, multi-lens approach of product profiling including breeding, gender, socio-economic and policy dimensions will help to ensure that new varieties are more likely to be picked by farmers and partner seed companies, and increase the impact of CIMMYT’s Global Maize Program.

Bottlenecks between basic and applied plant science jeopardize life-saving crop improvements

Written by Marcia MacNeil on September 3, 2019. Posted in News.

Visitors at CIMMYT’s experimental station in Obregon, Mexico, where elite wheat lines are tested for new traits.

For a number of reasons, including limited interdisciplinary collaboration and a dearth of funding, revolutionary new plant research findings are not being used to improve crops.

“Translational research” — efforts to convert basic research knowledge about plants into practical applications in crop improvement — represents a necessary link between the world of fundamental discovery and farmers’ fields. This kind of research is often seen as more complicated and time consuming than basic research and less sexy than working at the “cutting edge” where research is typically divorced from agricultural realities in order to achieve faster and cleaner results; however, modern tools — such as genomics, marker-assisted breeding, high throughput phenotyping of crop traits using drones, and speed breeding techniques — are making it both faster and cost-effective.

In a new article in Crop Breeding, Genetics, and Genomics, wheat physiologist Matthew Reynolds of the International Maize and Wheat Improvement Center (CIMMYT) and co-authors make the case for increasing not only funding for translational research, but the underlying prerequisites: international and interdisciplinary collaboration towards focused objectives and a visionary approach by funding organizations.

“It’s ironic,” said Reynolds. “Many breeding programs have invested in the exact technologies — such as phenomics, genomics and informatics — that can be powerful tools for translational research to make real improvements in yield and adaptation to climate, disease and pest stresses. But funding to integrate these tools in front-line breeding is quite scarce, so they aren’t reaching their potential value for crop improvement.”

Many research findings are tested for their implications for wheat improvement by the International Wheat Yield Partnership (IWYP) at the IWYP Hub, a centralized technical platform for evaluating innovations and building them into elite wheat varieties, co-managed by CIMMYT at its experimental station in Obregon, Mexico.

IWYP has its roots with the CGIAR Research Program on Wheat (WHEAT), which in 2010 formalized the need to boost both wheat yield potential as well as its adaptation to heat and drought stress. The network specializes in translational research, harnessing scientific findings from around the world to boost genetic gains in wheat, and capitalizing on the research and pre-breeding outputs of WHEAT and the testing networks of the International Wheat Improvement Network (IWIN). These efforts also led to the establishment of the Heat and Drought Wheat Improvement Consortium (HeDWIC).

“We’ve made extraordinary advances in understanding the genetic basis of important traits,“ said IWYP’s Richard Flavell, a co-author of the article. “But if they aren’t translated into crop production, their societal value is lost.”

The authors, all of whom have proven track records in both science and practical crop improvement, offer examples where exactly this combination of factors led to the impactful application of innovative research findings.

Improving the Vitamin A content of maize: A variety of maize with high Vitamin A content has the potential to reduce a deficiency that can cause blindness and a compromised immune system. This development happened as a result of many translational research efforts, including marker-assisted selection for a favorable allele, using DNA extracted from seed of numerous segregating breeding crosses prior to planting, and even findings from gerbil, piglet and chicken models — as well as long-term, community-based, placebo-controlled trials with children — that helped establish that Vitamin A maize is bioavailable and bioefficacious.
Flood-tolerant rice: Weather variability due to climate change effects is predicted to include both droughts and floods. Developing rice varieties that can withstand submergence in water due to flooding is an important outcome of translational research which has resulted in important gains for rice agriculture. In this case, the genetic trait for flood tolerance was recognized, but it took a long time to incorporate the trait into elite germplasm breeding programs. In fact, the development of flooding tolerant rice based on a specific SUB 1A allele took over 50 years at the International Rice Research Institute in the Philippines (1960–2010), together with expert molecular analyses by others. The translation program to achieve efficient incorporation into elite high yielding cultivars also required detailed research using molecular marker technologies that were not available at the time when trait introgression started.

Other successes include new approaches for improving the yield potential of spring wheat and the discovery of traits that increase the climate resilience of maize and sorghum.

One way researchers apply academic research to field impact is through phenotyping. Involving the use of cutting edge technologies and tools to measure detailed and hard to recognize plant traits, this area of research has undergone a revolution in the past decade, thanks to more affordable digital measuring tools such as cameras and sensors and more powerful and accessible computing power and accessibility.

Scientists are now able to identify at a detailed scale plant traits that show how efficiently a plant is using the sun’s radiation for growth, how deep its roots are growing to collect water, and more — helping breeders select the best lines to cross and develop.

An Australian pine at CIMMYT’s experimental station in Texoco, Mexico, commemorates the 4th symposium of the International Plant Phenotyping Network.

Phenotyping is key to understanding the physiological and genetic bases of plant growth and adaptation and has wide application in crop improvement programs. Recording trait data through sophisticated non-invasive imaging, spectroscopy, image analysis, robotics, high-performance computing facilities and phenomics databases allows scientists to collect information about traits such as plant development, architecture, plant photosynthesis, growth or biomass productivity from hundreds to thousands of plants in a single day. This revolution was the subject of discussion at a 2016 gathering of more than 200 participants at the International Plant Phenotyping Symposium hosted by CIMMYT in Mexico and documented in a special issue of Plant Science.

There is currently an explosion in plant science. Scientists have uncovered the genetic basis of many traits, identified genetic markers to track them and developed ways to measure them in breeding programs. But most of these new findings and ideas have yet to be tested and used in breeding programs, wasting their potentially enormous societal value.

Establishing systems for generating and testing new hypotheses in agriculturally relevant systems must become a priority, Reynolds states in the article. However, for success, this will require interdisciplinary, and often international, collaboration to enable established breeding programs to retool. Most importantly, scientists and funding organizations alike must factor in the long-term benefits as well as the risks of not taking timely action. Translating a research finding into an improved crop that can save lives takes time and commitment. With these two prerequisites, basic plant research can and should positively impact food security.

Nepal’s seed sector partners join forces to realize the National Seed Vision 2013-2025

Written by Rodrigo Ordóñez on August 20, 2019. Posted in Features.

Access to affordable quality seed is one of the prerequisites to increase agricultural production and improve the livelihoods of Nepali farmers. However, there are significant challenges to boost Nepal’s seed industry and help sustainably feed a growing population.

Six years ago, Nepal launched its National Seed Vision 2013-2025. This strategic plan aims at fostering vibrant, resilient, market-oriented and inclusive seed systems in public-private partnership modalities, to boost crop productivity and enhance food security.

The Nepal Seed and Fertilizer (NSAF) project, led by the International Maize and Wheat Improvement Center (CIMMYT), is supporting the government to enhance national policies and guidelines, and private seed companies to build competitive seed businesses and hybrid seed production.

Quality seed can increase crop yield by 15-20%. However, there are critical challenges hindering the growth of Nepal’s seed industry. Existing seed replacement rate for major cereals is low, around 15%. About 85% of Nepali farmers are unable to access recently developed improved seeds — instead, they are cultivating decades-old varieties with low yield and low profits. Some of the factors limiting the development of seed systems are the high cost of seed production and processing, the limited reach of mechanization, and the low use of conservation agriculture practices.

The demand for hybrid seeds in Nepal is soaring but research in variety development is limited. Most of the country’s supply comes from imports.

In collaboration with the Nepal Agricultural Research Council (NARC), the NSAF project team is working with seed companies and cooperatives to scale hybrid seed production of maize, tomato and rice. Through this project, CIMMYT collaborated with the Seed Quality Control Center (SQCC) and national commodity programs of the NARC to draft the first hybrid seed production and certification guidelines for Nepal to help private seed companies produce and maintain standards of hybrid seeds.

Extension and promotion activities are essential to bring improved seed varieties to farmers. Standard labelling and packaging also needs to be strengthened.

A joint effort

CIMMYT and its partners organized a two-day workshop to review the progress of the National Seed Vision. The event attracted 111 participants from government institutions, private companies and development organizations engaged in crop variety development, seed research, seed production and dissemination activities.

In the opening remarks, Yubak Dhoj G.C., Secretary of Nepal’s Ministry of Agriculture and Livestock Development, addressed the seed sector scenario and its challenges. He stressed the importance of collaboration among seed stakeholders to meet the targets of the National Seed Vision in the next six years.

During the technical sessions, Madan Thapa, Chief of the SQCC, analyzed the current status of the National Seed Vision and highlighted the challenges as well as the opportunities to realize it.

Laxmi Kant Dhakal, Chairperson of the Seed Entrepreneurs Association of Nepal (SEAN) emphasized the importance of private sector engagement and other support areas to strengthen seed production and marketing of open-pollinated varieties and hybrids.

Tara Bahadur Ghimire, Principal Scientist at NARC, gave an overview of the status of NARC varieties, source seed and resource allocation.

Dila Ram Bhandari, former Chief of SQCC, led a discussion around the assumptions and expectations that arose while developing the National Seed Vision.

Technical leads of maize, rice, wheat and vegetables presented a road map on hybrid variety development and seed production in line with the National Seed Vision’s targets for each crop.

“A large quantity of hybrid seeds, worth millions of dollars, is being imported into Nepal each year,” explained AbduRahman Beshir, Seed Systems Lead of CIMMYT’s NSAF project. “However, if stakeholders work together and strengthen the local seed system, there is a huge potential in Nepal not only to become self-sufficient but also to export good quality hybrid seeds in the foreseeable future. Under the NSAF project we are witnessing a few seed companies that have initiated hybrid seed production of maize and tomato.”

In one of the exercises, workshop participants were divided in groups and examined different topics related to the realization of the National Seed Vision. They looked at genetic resources, hybrid and open-pollinated variety development, source seed production and supply, private sector engagement and marketing, seed extension and varietal adoption by farmers, seed quality control services, and roles of research partners and other stakeholders. The groups presented some of the major challenges and opportunities related to these topics, as well as recommendations, which will be documented and shared.

The outcomes of this mid-term review workshop will inform policy and guide the discussions at the upcoming International Seed Conference to be held in early September 2019.

Regulating hybrid seed production

At the workshop, participants thoroughly discussed the draft hybrid seed production and certification guidelines, developed under the NSAF project.

The guidelines are the first of their kind in Nepal and essential to achieve the targets of the National Seed Vision, by engaging the private sector in hybrid seed production.

Hari Kumar Shrestha, CIMMYT’s Seed Systems Officer, and other seed experts from the SQCC presented the main features and regulatory implications of the guidelines.

After the workshop, the guidelines were sent to the National Seed Board for approval.
