New publications: Identifying common genetic bases for yield, biomass and radiation use efficiency in spring wheat

UAV_HiBAP2017

For plant scientists, increasing wheat yield potential is one of the most prevalent challenges of their work. One key strategy for increasing yield is to improve the plant’s ability to produce biomass through optimizing the conversion of solar radiation into plant structures and grain, called radiation use efficiency (RUE). Currently, the process is 30-50% less efficient in wheat than in maize.

International Maize and Wheat Improvement Center (CIMMYT) wheat physiologist Gemma Molero, in collaboration with Ryan Joynson and Anthony Hall of the Earlham Institute, has been studying the association of RUE related traits with molecular markers to identify specific genes associated with this trait.

In December 2018, her team published their results in the article “Elucidating the genetic basis of biomass accumulation and radiation use efficiency in spring wheat and its role in yield potential,” shedding light on some of the genetic bases of biomass accumulation and RUE in a specially designed panel of lines that included material with diverse expression of RUE over the wheat crop cycle.

Over the course of two years, Molero and fellow researchers evaluated a panel of 150 elite spring wheat genotypes for 31 traits, looking for marker traits associated with yield and other “sink”-related traits, such as, grain number, grain weight and harvest index, along with ‘’source’’-related traits, such as RUE and biomass at various growth stages.  Many of the elite wheat lines that were tested encompass “exotic” material in their pedigree such as ancient wheat landraces and wheat wild relatives.

The scientists found that increases in both net rate of photosynthesis and RUE have the potential to make a large impact on wheat biomass, demonstrating that the use of exotic material is a valuable resource to help increase yield potential. This is the first time that a panel of elite wheat lines has been assembled using different sources of yield potential traits, and an important output from a large global endeavor to increase wheat yield, the International Wheat Yield Partnership (IWYP).

“We identified common genetic bases for yield, biomass and RUE for the first time. This has important implications for wheat researchers, breeders, geneticists, plant scientists and biologists,” says Molero.

The identification of molecular markers associated with the studied traits is a valuable tool for wheat improvement. Broadly speaking, the study opens the door for a series of important biological questions about the role of RUE in yield potential and in the ability to increase grain biomass.

In order to accommodate worldwide population increases and shifts in diet, wheat yield needs to double by 2050 — and genetic gains in wheat, specifically, must increase at a rate of 2.4 percent annually. Increasing biomass through the optimization of RUE along the wheat crop cycle can be an important piece in the puzzle to help meet this demand.

MEXICO CITY (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT) was invited to discuss the findings of the EAT-Lancet Commission report and its implications for Mexico, during a launch event hosted by Mexico’s Health Department on March 4, 2019.

The report, published earlier this year, aims to offer an in-depth scientific analysis of the world’s food production systems and their impact on the planet and human health. It proposes a “planetary health diet” that balances nutrition with sustainable food production.

“Our first objective was to develop healthy diets for the 10 billion people who will inhabit the planet in 2050”, said Juan Ángel Rivera Dommarco, Director General of Mexico’s Public Health Institute and member of the EAT-Lancet Commission. According to Dommarco, the healthy diet recommended for Mexico had to increase the intake of fruits, vegetables, legumes and whole grains to avert chronic diseases and combat malnutrition and obesity.

The report also makes several recommendations to reduce the environmental impact of food production, taking into account planetary boundaries. “The world needs to sustainably intensify food production and to produce basic foodstuffs of higher nutritional value”, said Fabrice DeClerck, EAT’s Science Director.

“If anybody is able to manage the complex systems that will sustainably yield the volume of nutritious food that the world needs, that’s the farmer”, said Bram Govaerts, Director of Innovative Business Strategies at CIMMYT. “In Mexico, more than 500 thousand farmers already innovate every day and grow maize, wheat and related crops under sustainable intensification practices that CIMMYT and Mexico’s Agriculture Department promote with MasAgro”.

Víctor Villalobos Arámbula, Mexico’s Secretary of Agriculture, said that the EAT-Lancet Commission report recommendations were very much in line with the strategic public policies that Mexico plans to implement in the coming years.

International Women’s Day 2019: Women in seed systems in Africa

The maize seed sector in eastern and southern Africa is male-dominated. Most seed companies operating in the region are owned and run by men. Access to land and financial capital can often be a constraint for women who are keen on investing in agriculture and agribusiness. However, there are women working in this sector, breaking social barriers, making a contribution to improving household nutrition and livelihoods by providing jobs and improved seed varieties.

The Gender team within the International Maize and Wheat Improvement Center’s (CIMMYT) Socioeconomics Program conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies. The resulting stories will be published as a report in May 2019.

These women in leading roles serve as mentors and examples to both male and female employees. In honor of International Women’s Day, held March 8, 2019, CIMMYT would like to share some of their stories to recognize these women — and many others like them — and the important work they do in seed systems in Africa.

Sylvia Horemans started Kamano Seeds in April 2004 together with her late husband Desire Horemans. The company derives its name from a stream that runs through their farm in Mwinilinga, Zambia. Kamano means a stream that never dries, aptly describing the growth the company has enjoyed over the years, enabling it to capture 15 percent of the country’s seed market share.  Sylvia became the company’s Chief Executive Officer in 2016.

“The initial business was only to sell commercial products but we realized there was a high demand for seed so we decided to start our own seed business,” says Sylvia. “We work with cooperatives which identify ideal farmers to participate in seed production.”

The company takes pride in the growth they have witnessed in their contract workers. “Most farmers we started with [now] have 20 to 40 hectares. Some are businessmen and have opened agrodealer shops where they sell agricultural inputs,” Sylvia announced.

Kamano prides itself in improving the lives of women smallholders and involving women in decision-making structures. “We empower a lot of women in agriculture through our out-grower scheme,” says Sylvia. She makes a deliberate effort to recruit women farmers, ensuring they receive payment for their seeds. “We pay the women who did the work and not their husbands.”

Zubeda Mduruma, 65, is a plant breeder. She took to agriculture from a young age, as she enjoyed helping her parents in the family farm. After high school, Zubeda obtained a bachelor’s degree in Agriculture. Then she joined Tanzania’s national agriculture research system, working at the Ilonga Agricultural Research Institute (ARI-Ilonga) station. She then pursued her master’s in Plant Breeding and Biometry from Cornell University in the United Stations and obtained a doctorate in Plant Breeding at Sokoine University of Agriculture in Tanzania, while working and raising her family. “I wanted to be in research, so I could breed materials which would be superior than what farmers were using, because they were getting very low yields,” says Zubeda. In the 22 years she was at Ilonga, Zubeda was able to release 15 varieties.

Aminata Quality Seeds is a family business that was registered in 2008, owned by Zubeda, her husband and their four daughters. Aminata entered the seed market as an out-grower, producing seed for local companies for two years. The company started its own seed production in 2010, and the following year it was marketing improved varieties. “I decided to start a company along the Coast and impart my knowledge on improved technologies, so farmers can get quality crops for increased incomes,” says Zubeda.

Zubeda encourages more women to venture into the seed business. “To do any business, you have to have guts. It is not the money; it is the interest. When you have the interest, you will always look for ways on how to start your seed business.”

Grace Malindi, 67, started Mgom’mera in Malawi in 2014 with her sister Florence Kahumbe, who had experience in running agrodealer shops. Florence was key in setting up the business, particularly through engagement with agro-dealers, while Grace’s background in extension was valuable in understanding their market. Grace has a doctoral degree in Human and Community Development with a double minor in Gender and International Development and Agriculture Extension and Advisory from the University of Illinois Urbana-Champaign in the United States. Mgom’mera is a family-owned enterprise. Grace’s three children are involved in the business, serving as directors.

Mgom’mera distinguishes itself from other seed companies because of its focus on maize varieties that have additional nutritive value. The company uses the tagline “Creating seed demand from the table to the soil.” It educates farmers not only on how to plant the seed they sell, but also on how to prepare nutritious dishes with their harvest. The company stocks ZM623, a drought-tolerant open-pollinated variety, and Chitedze 2, a quality protein maize. In the 2019 maize season it will also sell MH39, a pro-vitamin A variety. In addition, they are looking forward to beginning quality protein maize hybrid production in the near future, having started the process of acquiring materials from CIMMYT.

Grace observes that women entrepreneurs are late entrants in seed business. “You need agility, flexibility and experience to run a seed business and with time you will improve,” says Grace, advising women who may be interested in venturing into this male-dominated business.

A new beginning for CIMMYT’s Seed Health Unit

Twenty years flew by for Monica Mezzalama, now former Pathologist and Head of the Seed Health Unit at the International Maize and Wheat Improvement Center (CIMMYT). At the end of January 2019, she made her way back to her hometown of Turin, Italy. Looking back at her tenure, Monica told us she felt “overwhelmed” by the opportunities that CIMMYT has given her.

Founded in 1988, the CIMMYT Seed Health lab began with five employees, eventually expanding to eight people. With Mezzalama at the helm since 2001, the unit has become a crucial part of CIMMYT’s operation in conducting global and national germplasm exchanges. Some would say that seed distribution is the “lifeblood” of CIMMYT.

Around the world, CIMMYT is known as a reliable distributor of seeds. According to Mezzalama, this is crucial not only for farmers but for other researchers. Without proper regulatory precautions, one can jeopardize the work of others when handling pathogens that can affect seeds.

CIMMYT distributes seed in collaboration with more than 100 countries worldwide, many of which don’t receive support or seed from any other institution. According to Mezzalama, “CIMMYT’s reputation is on the line,” if healthy, quality seed is not delivered. Under Mezzalama’s watch there were never such problems with CIMMYT seeds.

Seeds are judged on appearances and must be good-looking as well as healthy. “Presentation standards are key because genetics aren’t immediately seen when the seeds are delivered,” Mezzalama states. If unattractive seed is discarded, then money is metaphorically being thrown away. Beyond saving money, quality seed control conducted by the Seed Health Unit helps keep data fresh and research up to date.

Good seed health depends on leadership like that from Mezzalama. Among the accomplishments of her two-decade tenure at CIMMYT, she formed and led a team that has responded quickly and effectively to emerging maize and wheat disease epidemics. In the midst of finding solutions to phytosanitary and biosafety challenges, she also took time to mentor young scientists and colleagues.

Monica Mezzalama will be moving on to the University of Turin in Italy to take on a new challenge in the academic world as a professor of Phytopathology. She expressed sadness at leaving CIMMYT, but gratitude at the opportunities CIMMYT has given her to grow professionally and the freedom to explore and experiment within her laboratory.

Mezzalama’s work and the team she leaves behind provide a strong base for continued safeguarding of CIMMYT’s international seed distribution efforts under her successor’s leadership. Down the road, Mezzalama hopes to maintain collaboration with CIMMYT in sustainable agricultural efforts.

Drought-tolerant hybrid seed offers farmers reprieve from hunger

MACHAKOS, Kenya (CIMMYT) — The scorching heat from the sun does not stop Mary Munini, a middle-aged smallholder farmer in Vyulya, Machakos County, from inspecting her distressed maize crop. Traces of worry cloud her face. “I will not harvest anything this season,” she says, visibly downcast.

Like many other smallholder farmers spread across the water-stressed counties of Machakos, Makueni and Kitui, in Kenya’s lower eastern region, Munini is staring at a massive crop loss. Prolonged dry spells have for years threatened the food security and livelihoods of many rural families in the region who depend entirely on rain for their agricultural production. Here, most smallholder farmers typically plant farm-saved maize seeds, which lack the attributes to tolerate harsher droughts, extreme heat or water stress. With such conditions, farmers can hardly harvest any maize.

“We just had a little rain at the start of planting. Since then, we have not had any more rain. As you can see, my maize could not withstand the extended dry spell,” says Munini. Like her, over 80 percent of Kenyans depend on maize as their main staple food to supply their dietary requirements, especially in rural areas.

In a neighboring farm, the situation is different. The owner, Gitau Gichuru, planted the SAWA hybrid, an improved maize seed variety designed to withstand drought conditions. This variety was developed by scientists at the International Maize and Wheat Improvement Center (CIMMYT) and promoted to Kenyan farmers by Dryland Seed, a local seed company. This initiative to improve maize farmers’ climate resilience in the region was possible thanks to the support of the Bill & Melinda Gates Foundation under the Stress Tolerant Maize for Africa (STMA) project. With the right agronomic practices, the SAWA hybrid can return a yield advantage of up to 20 percent compared to other popular drought-tolerant hybrids in the region, according to Dryland Seed’s managing director, Ngila Kimotho.

“This variety has become so popular in this region that we have decided to make it our flagship brand. There are occasions when the demand is so high that we run out of stock,” Kimotho says.

Reaping the benefits

The company distributes improved seeds through a network of about 100 agrodealers across Kenya. One of the most effective ways to promote drought-tolerant hybrids such as SAWA is demonstration plots managed by lead farmers, who can showcase to their peers the hybrid’s performance under recommended agronomic practices. Most of the demo farms are located by the roadside for better visibility to road users, who frequently stop and ask about the healthy-looking maize crop. Field days have also had a positive effect of creating awareness and getting farmers to adopt the SAWA hybrid and other improved seed varieties. Farmers attending field days are ordinarily issued with small seed packs as samples to try out on their farms.

Gichuru, who planted the SAWA hybrid maize seed for the first time last season, is happy with the results. “I decided to try it on a portion of the land that is sandy. We have only had some little rain, twice or so, at the time of planting and during the vegetative state. To be honest, I didn’t expect the crop to amount to anything. But, as you can see, I am looking forward to a good harvest,” Gichuru says.

Doris Muia, a mother of three who has planted the hybrid for two years at her farm, is equally happy with the outcome. She says her household will never lack food and she hopes to get additional income from the sale of the surplus maize produce.

“When we see how the varieties that we have developed such as the SAWA hybrid are putting smiles on farmers’ faces, this makes us very happy,” expresses Stephen Mugo, CIMMYT Regional Representative for Africa.

For some farmers, however, it is hard to gather the money to buy improved seed varieties. The little income Munini earns from her small shop goes towards supporting her children’s education, and she often has nothing left to buy improved hybrid seed varieties, despite being aware of the advantages. In other instances, some farmers often buy small portions of the improved maize variety and mix it with farm-saved seed stock or poor-quality seeds from informal sources.

“The expectation is that if one variety succumbs to drought or severe heat, the next variety may survive. However, with proper agricultural practices, hybrids such as SAWA can cope well against such climate stresses, thereby improving the smallholders’ livelihood and food security,” concludes Mugo.

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 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.

New publications: Gender and agricultural innovation in Oromia region, Ethiopia

Despite formal decentralization, agricultural services in Ethiopia are generally “top-down,” claim the authors of a recently published paper on gender and agricultural innovation. “Extension services,” they explain, “are supply-driven, with off-the-shelf technologies transferred to farmers without expectation of further adaptation.”

Drawing on GENNOVATE case studies from two wheat-growing communities in Ethiopia’s Oromia region, the authors examine how a small sample of women and men smallholders attempt to innovate with improved wheat seed, row planting, and the broad bed maker, introduced through the Ethiopian agricultural extension system. They also introduce the concept of tempered radicals, an analytic lens used to understand how individuals try to initiate change processes, and assess whether this can have validity in rural settings.

As the authors demonstrate through their literature review on cultural norms in the region, there are powerful institutional gender constraints to change processes, which can be punitive for women.

Ethiopian women smallholders are particularly disadvantaged because they have limited access to productive assets such as irrigation water, credit and extension services. Therefore, they find it harder to implement innovations. The study asserts that strategies to support innovators, and women innovators in particular, must be context-specific as well as gender-sensitive.

For many small farmers across sub-Saharan Africa, the crop yields their livelihoods depend on are affected by low-quality inputs and severe challenges like climate change, pests and diseases. Unsustainable farming practices like monocropping are impacting soil health and reducing the productivity of their farms.

Sustainable intensification practices based on conservation agriculture entail minimal soil disturbance, recycling crop plant matter to cover and replenish the soil, and diversified cropping patterns. These approaches maintain moisture, reduce erosion and curb nutrient loss. Farmers are encouraged and supported to intercrop maize with nitrogen-fixing legumes — such as beans, peas and groundnuts — which enrich the soil with key nutrients. Farmers are equally advised to cultivate their crops along with trees, instead of deforesting the land to create room for farming.

These practices result in higher incomes for farmers and better food and nutrition for families. Adopting conservation agriculture also improves farmers’ climate resilience. Combined with good agronomic practices, conservation agriculture for sustainable intensification can increase yields up to 38 percent.

Since 2010, the Sustainable Intensification of Maize and Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project has promoted effective ways to produce more food while protecting the environment across Eastern and Southern Africa. In particular, the SIMLESA project aims at sustainably increasing the productivity of maize and legume systems in the region.

The SIMLESA project demonstrated the advantages of deploying low-carbon and low-cost mechanization adapted to smallholder farming: it addresses labor shortages at critical times like planting or weeding, boosting farmers’ productivity and yields. The SIMLESA project introduced mechanization in different phases: first improved manual tools like the jab planter, later draft power machinery innovations such as rippers, and finally motorized mechanization in the form of small four-wheel tractors.

From proof of concept to nation-wide adoption

In Mozambique, conservation agriculture-based sustainable intensification practices have significantly expanded: from 36 farmers in six villages in four districts in 2010, to over 190,000 farmers in more than 100 villages in nine districts by the end of 2018. This remarkable result was achieved in collaboration with partners such as the Mozambican Agricultural Research Institute (IIAM), extension workers, communities and private companies.

“Smallholder agriculture mechanization reduced the amount of labor required for one hectare of land preparation, from 31 days to just 2 hours. This enabled timely farming activities and a maize yield increase of about 170 kg per hectare, reflecting an extra 3-4 months of household food security,” said the national coordinator for SIMLESA in Mozambique, Domingos Dias.

Following its successes, SIMLESA and its partners have embarked on a series of meetings to discuss how to leverage public-private partnerships to expand conservation agriculture practices to other regions.

Throughout February and March 2019, a series of policy forums at sub-national and national levels will be held across the seven SIMLESA countries: Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Tanzania and Uganda.

The first policy dialogue took place on February 7 in Chimoio, in Mozambique’s district of Manica. Key agriculture stakeholders attended, including representatives from CIMMYT, IIAM, the Ministry of Agriculture, as well as policy makers, private sector partners and international research institutes.

“We are delighted at SIMLESA’s unique strategy of involving multiple partners in implementing conservation agriculture for sustainable intensification practices. This has, over the years, allowed for faster dissemination of these practices and technologies in more locations in Mozambique, thereby increasing its reach to more farmers,” said Albertina Alage, Technical Director for Technology Transfer at IIAM. “Such policy forums are important to showcase the impact of conservation agriculture to policy makers to learn and sustain their support for scaling up conservation agriculture for sustainable intensification,” she added.

Forum participants called for better coordination between the public and the private sector to deliver appropriate machinery for use by smallholders in new areas. They recommended adequate support to enable farmers to better integrate livestock and a diverse cropping system, as well as continue with conservation agriculture trials and demonstration activities. Besides involving farmers, their associations and agro-dealer networks in scaling conservation agriculture initiatives, participants agreed to promote integrated pest and disease management protocols. This is considering the recent outbreak of the fall armyworm, which devasted crops in many countries across sub-Saharan Africa.

“The SIMLESA project is and will always be a reference point for our research institute and the Ministry of Agriculture in our country. The good progress of SIMLESA and the results of this forum will help to draw strategies for continuity of this program implemented by government and other programs with the aim to increase production and productivity of farmers,” Alage concluded.

The SIMLESA project is a science for development alliance, funded by the Australian Centre for International Agricultural Research (ACIAR) and led by the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with national research institutes in Ethiopia, Kenya, Malawi, Mozambique and Tanzania.

The missing seed market

In Ethiopia, a World Bank study found that female farm managers produce 23 percent less yield per hectare compared to their male counterparts. This difference is explained partly by unequal access to information on improved seed varieties and what best agricultural practices to use. Despite half the farming workforce being women, the seed companies do not typically adapt their seed marketing strategy according to gender.

The “Gender-Responsive Approaches for the Promotion of Improved Maize Seed in Africa” guidebook, developed by the International Maize and Wheat Improvement Center (CIMMYT), is filling this gap. Designed for seed companies, extension workers and development organizations, it explains how best to package information about improved seed and farming technologies for men and women, with the goal of increasing adoption rates.

“Since seeing is believing, the field demonstrations approach allows farmers to witness firsthand how well improved seed varieties perform on their farms right from planting to harvesting, compared to old or other varieties,” said Rahma Adam, gender and development specialist at CIMMYT. “But too often, not enough care is given in the selection of women as lead farmers. This minimizes opportunities for reaching out to more women.”

Based on research, the guidebook recommends that half of the demonstration plots should be managed by women. In fact, the panel of lead farmers should be diverse, representing different age, socioeconomic status and ethnic groups, among others. Indeed, an understanding and importance of the various agronomic practices from the time of planting, weed control or fertilizer application would vary across gender, age and socioeconomic groups.

“Given the turnover of seed varieties due to genetic improvements, men and women extension workers need to keep abreast not only of new technologies, but also of new ways of fostering awareness and encouraging adoption, for instance using digital platforms for faster and cheaper outreach,” the guidebook concludes.

Tools for field days and budgeting

A complementary handbook, “Gender-responsive tools for demos and field days data collection”, is under preparation. It will guide seed companies and extension workers on how to consider the diversity of the public attending farmer field days.

Another toolkit, “Gender-Responsive Budgeting Tool for the Promotion of Improved Maize Seed in Africa”, proposes how to efficiently allocate resources to reach out to targeted farmers to promote new varieties and farming practices. If, for instance, women farmers do not know as much as men farmers about certain improved maize varieties, then the best approach would be to direct the resources towards promoting the seed varieties among the women. Better still, since women are involved in making decisions about purchasing improved seeds in both male-headed and female-headed households, it is logical to allocate more resources targeting women farmers. An effective strategy would be to allocate a portion of the budget to field days, farm demonstrations, distribution of small seed packs, informational leaflets, showcase videos and disseminate radio messages, among others. “In fact, local radio is quite effective in informing farmers about upcoming field days or farm demonstration days,” said Simon Kiio, a field officer at Dryland Seed Ltd, a Kenyan seed company which distributes drought-tolerant SAWA and VIGA maize hybrids, among others, across Kenya.

“Whenever we make announcements on local radio to inform farmers about dates and locations for demo farm activities, we usually get more women attending than men. These women act as good marketing ambassadors for our products within their networks or groups,” Kiio explained.

Ultimately, by building gender-sensitive and cost-effective seed promotion programs, seed companies would generate more seed sales of improved maize varieties: seeds that are more tolerant to major stresses, better adapted to poor soils, and yielding more than the local, older varieties on the market.

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 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.

Assessing the effectiveness of a “wheat holiday” for preventing blast in the lower Gangetic plains

Wheat blast — one of the world’s most devastating wheat diseases — is moving swiftly into new territory in South Asia.

In an attempt to curb the spread of this disease, policymakers in the region are considering a “wheat holiday” policy: banning wheat cultivation for a few years in targeted areas. Since wheat blast’s Magnaporthe oryzae pathotype triticum (MoT) fungus can survive on seeds for up to 22 months, the idea is to replace wheat with other crops, temporarily, to cause the spores to die. In India, which shares a border of more than 4,000 km with Bangladesh, the West Bengal state government has already instituted a two-year ban on wheat cultivation in two districts, as well as all border areas. In Bangladesh, the government is implementing the policy indirectly by discouraging wheat cultivation in the severely blast affected districts.

CIMMYT researchers recently published in two ex-ante studies to identify economically feasible alternative crops in Bangladesh and the bordering Indian state of West Bengal.

Alternative crops

The first step to ensuring that a ban does not threaten the food security and livelihoods of smallholder farmers, the authors assert, is to supply farmers with economically feasible alternative crops.

In Bangladesh, the authors examined the economic feasibility of seven crops as an alternative to wheat, first in the entire country, then in 42 districts vulnerable to blast, and finally in ten districts affected by wheat blast. Considering the cost of production and revenue per hectare, the study ruled out boro rice, chickpeas and potatoes as feasible alternatives to wheat due to their negative net return. In contrast, they found that cultivation of maize, lentils, onions, and garlic could be profitable.

The study in India looked at ten crops grown under similar conditions as wheat in the state of West Bengal, examining the economic viability of each. The authors conclude that growing maize, lentils, legumes such as chickpeas and urad bean, rapeseed, mustard and potatoes in place of wheat appears to be profitable, although they warn that more rigorous research and data are needed to confirm and support this transition.

Selecting alternative crops is no easy task. Crops offered to farmers to replace wheat must be appropriate for the agroecological zone and should not require additional investments for irrigation, inputs or storage facilities. Also, the extra production of labor-intensive and export-oriented crops, such as maize in India and potatoes in Bangladesh, may add costs or require new markets for export.

There is also the added worry that the MoT fungus could survive on one of these alternative crops, thus completely negating any benefit of the “wheat holiday.” The authors point out that the fungus has been reported to survive on maize.

A short-term solution?

In both studies, the authors discourage a “wheat holiday” policy as a holistic solution. However, they leave room for governments to pursue it on an interim and short-term basis.

In the case of Bangladesh, CIMMYT agricultural economist and lead author Khondoker Mottaleb  asserts that a “wheat holiday” would increase the country’s reliance on imports, especially in the face of rapidly increasing wheat demand and urbanization. A policy that results in complete dependence on wheat imports, he and his co-authors point out, may not be politically attractive or feasible. Also, the policy would be logistically challenging to implement. Finally, since the disease can potentially survive on other host plants, such as weeds and maize, it may not even work in the long run.

In the interim, the government of Bangladesh may still need to rely on the “wheat holiday” policy in the severely blast-affected districts. In these areas, they should encourage farmers to cultivate lentils, onions and garlic. In addition, in the short term, the government should make generic fungicides widely available at affordable prices and provide an early warning system as well as adequate information to help farmers effectively combat the disease and minimize its consequences.

In the case of West Bengal, India, similar implications apply, although the authors conclude that the “wheat holiday” policy could only work if Bangladesh has the same policy in its blast-affected border districts, which would involve potentially difficult and costly inter-country collaboration, coordination and logistics.

Actions for long-term success

The CIMMYT researchers urge the governments of India and Bangladesh, their counterparts in the region and international stakeholders to pursue long-term solutions, including developing a convenient diagnostic tool for wheat blast surveillance and a platform for open data and science to combat the fungus.

A promising development is the blast-resistant (and zinc-enriched) wheat variety BARI Gom 33 which the Bangladesh Agricultural Research Institute (BARI) released in 2017 with support from CIMMYT. However, it will take at least three to five years before it will be available to farmers throughout Bangladesh. The authors urged international donor agencies to speed up the multiplication process of this variety.

CIMMYT scientists in both studies close with an urgent plea for international financial and technical support for collaborative research on disease epidemiology and forecasting, and the development and dissemination of new wheat blast-tolerant and resistant varieties and complementary management practices — crucial steps to ensuring food security for more than a billion people in South Asia.

Wheat blast impacts

First officially reported in Brazil in 1985, where it eventually spread to 3 million hectares in South America and became the primary reason for limited wheat production in the region, wheat blast moved to Bangladesh in 2016. There it affected nearly 15,000 hectares of land in eight districts, reducing yield by as much as 51 percent in the affected fields.

Blast is devilish: directly striking the wheat ear, it can shrivel and deform the grain in less than a week from the first symptoms, leaving farmers no time to act. There are no widely available resistant varieties, and fungicides are expensive and provide only a partial defense. The disease, caused by the fungus Magnaporthe oryzae pathotype triticum (MoT), can spread through infected seeds as well as by spores that can travel long distances in the air.

South Asia has a long tradition of wheat consumption, especially in northwest India and Pakistan, and demand has been increasing rapidly across South Asia. It is the second major staple in Bangladesh and India and the principal staple food in Pakistan. Research indicates 17 percent of wheat area in Bangladesh, India, and Pakistan — representing nearly 7 million hectares – is vulnerable to the disease, threatening the food security of more than a billion people.

CIMMYT and its partners work to mitigate wheat blast through projects supported by U.S. Agency for International Development (USAID), the Bill & Melinda Gates Foundation, the Australian Centre for International Agricultural Research (ACIAR), the Indian Council for Agricultural Research (ICAR), the CGIAR Research Program on Wheat and the CGIAR Platform for Big Data in Agriculture.

Women’s equality crucial for Ethiopia’s agricultural productivity

The Government of Ethiopia recently announced an ambitious goal to reach wheat self-sufficiency by 2022, eliminating expensive wheat imports and increasing food security.

However, a new report based on a four-year research project on gender and productivity in Ethiopia’s wheat sector indicates that a lack of technical gender research capacity, a shortage of gender researchers and low implementation of gender-focused policies is hampering these efforts.

New partnership announced for sustainable maize production in Colombia

Palmira (Colombia), February 14, 2019 — AGROSAVIA, Colombia’s leading not-for-profit organization for agricultural research and technology transfer, the International Center for Tropical Agriculture (CIAT) and the International Maize and Wheat Improvement Center (CIMMYT) have signed a five-year agreement that aims to boost maize production.

The new project will develop maize varieties adapted to the country’s farming conditions, and will promote sustainable intensification technologies and practices among Colombian farmers.

“We should be able to release the first high-yielding maize variety for Colombia in three years”, said Bram Govaerts, CIMMYT’s director of Innovative Business Strategies and regional representative for the Americas.

To achieve this goal, CIMMYT will provide AGROSAVIA’s breeding program with two thousand advanced lines, developed by combining native maize from Colombia with conventionally improved varieties.

“At both institutions we believe that Colombia can increase production to close the big gap between domestic maize consumption and imports”, said AGROSAVIA’s Executive Director, Juan Lucas Restrepo. “With this agreement, we will have more powerful local capacities and once again a Colombian maize research program for Colombians”.

Although experts agree that Colombian farmers could potentially produce more than 10 tons per hectare, the country’s average yield is currently 3.6 tons per hectare.

“With this agreement, the sister CGIAR centers CIMMYT and CIAT give a first step in the implementation of Maize for Colombia, an ambitious plan that will sustainably increase Colombia’s maize output by building on the learnings and achievements of a successful project implemented in Mexico called MasAgro,” said Govaerts.

Colombia’s Minister of Agriculture and Rural Development, Andrés Valencia, CIAT’s Director General, Rubén Echeverría, Juan Lucas Restrepo, and Bram Govaerts participated in the launch ceremony for the new agreement, which was signed at CIAT’s headquarters.
