CIMMYT’s work in Africa helps farmers access new maize and wheat systems-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains. Our activities in Africa are wide ranging and include: breeding maize for drought tolerance and low-fertility soils, and for resistance to insect pests, foliar diseases and parasitic weeds; sustainably intensifying production in maize- and wheat-based systems; and investigating opportunities to reduce micronutrient and protein malnutrition among women and young children.
Nominations are now open for the 2019 MAIZE Youth Innovators Awards – Africa! These awards are part of the efforts that the CGIAR Research Program on Maize (MAIZE) is undertaking to promote youth participation in maize-based agri-food systems. These awards recognize the contributions of young women and men below 35 years of age who are implementing innovations in African maize-based agri-food systems, including research for development, seed systems, agribusiness, and sustainable intensification.
Young people are the key to ensuring a food-secure future and agricultural sustainability. However, rural youth face many challenges related to unemployment, underemployment and poverty. According to the Food and Agriculture Organization (FAO) of the United Nations, facilitating young people’s participation in agriculture has the potential to drive widespread rural poverty reduction among young people and adults alike. In Africa, where over 300 million smallholder-farming families grow and consume maize as a staple crop, the human population stands at 1.2 billion people, 60 percent of whom are below the age of 25.
The MAIZE Youth Innovators Awards aim to identify young innovators who can serve to inspire other young people to get involved in maize-based agri-food systems. Part of the vision is to create a global network of young innovators in maize-based systems from around the world.
Award recipients will be invited to attend the annual Stress Tolerant Maize for Africa (STMA) project meeting in Lusaka, Zambia, from May 7 to May 9, where they will receive their awards and will be given the opportunity to present their work. The project meeting and award ceremony will also allow these young innovators to network and exchange experiences with MAIZE researchers and partners. Award recipients may also get the opportunity to collaborate with MAIZE and its partner scientists in Africa on implementing or furthering their innovations.
MAIZE invites young innovators to apply and CGIAR researchers and partners to nominate eligible applicants for any of the following three categories:

Many Kenyan maize farmers are busy preparing their seed stock for the next planting season. Sowing high quality seeds of stress-tolerant varieties is a cost-effective way for African smallholder farmers to boost their harvests while being resilient to evolving crop pests and diseases as well as an erratic climate. However, even if a majority of farmers buy their seeds, they are often of dubious quality or of old, outdated varieties, which do not cope well against increasing drought and heat shocks or emerging diseases.
Insufficient seed quality control
The African seed sector has long been plagued by counterfeit seeds and a complex and costly certification process, which hampers access to better, higher-yielding, wide-ranging varieties for farmers.
Since the 1990s, national agencies could not keep up with the seed trade growth to handle the certification processes. Backlogs of certification requests and erroneous seed checks make it costly for private seed companies to produce and commercialize new varieties. As a result, maize varieties grown by farmers in sub-Saharan Africa are old: 28 years old on average for hybrids and up to 40 years old for open-pollinated varieties.
“A lot of the national certification systems in the region are overwhelmed. They do not have enough seed inspectors with proper training and tools to carry out compliance checks effectively and in a timely manner. The licensing, labeling and branding protocols and regulations are equally not in full force, and much of the work still needs to be digitized. This slows the entire process,” said Kate Fehlenberg, Drought Tolerant Maize for Africa Seed Scaling (DTMASS) Project Manager at the International Maize and Wheat Improvement Center (CIMMYT), at a recent Common Market for Eastern and Southern Africa (COMESA) seed policies’ harmonization event in Nairobi.
Go digital
To solve this certification bottleneck, seed actors are looking at digital solutions for faster, more accurate seed quality checks for both seed producers and regulators. One Kenyan company, Cellsoft Ltd., has developed SeedAssure, a cloud-based platform that enables digital seed inspections. Data necessary for quality seed production, pest and disease surveillance, and the required checks to apply for a commercial license can be shared in real-time on a common platform that links seed companies, inspectors and local authorities. Such a tool not only enables optimal quality in seed production, but expedites the licensing, certification and trade processes with traceable data records.
SeedAssure is rapidly being rolled out across eastern and southern Africa with support across the seed value chain. This includes regional trade bodies like COMESA and the Southern African Development Community (SADC), national regulators such as the Seed Control and Certification Institute (SCCI), to research and development organizations like CIMMYT and the Alliance for a Green Revolution in Africa (AGRA). So far, 15 seed companies in seven countries in the region have been testing SeedAssure.
Transboundary data-sharing to boost regional seed trade

To boost regional seed trade, all actors along the seed value chain and across the region must embrace this digital revolution and “speak the same language”. This means adopting the same rules to identify and register a new variety, and using a common platform to easily share data between countries.
Currently, despite efforts to harmonize seed trade policies across the region, such as the COMESA Seed Harmonization Implementation Program (COMSHIP), passed in 2014, most countries still use different protocols to name and register seed varieties. One variety could have a different name in each country it is sold in. Data used for quality control are still often on paper rather than online, with each country performing its own tests. Seed companies must apply for new variety registration, with new data for each country they operate in. This all costs them time and money.
Adopting a unique identifier for seed products and digitalization can help alleviate this harmonization issue, easing comparable data sharing across border. Since November 2017, CIMMYT has adopted a Variety Identification Number (VIN) system. It is like a unique barcode for each variety which contains information about the organization that produced the variety, the year of release, the crop and specific traits such as drought-tolerance, the country where it is produced, etc. SADC and COMESA have just adopted this VIN system. COMSHIP is setting digital seed variety catalogues using the VIN, and soon regional seed labels. It will facilitate cross-border seed trade and help track seed fraud.
The 2019 Global Forum for Food and Agriculture (GFFA) held this week in Berlin is debating how digitalization is transforming the farming sector. This is particularly relevant for the African seed sector as digital innovations could make seed certification and quality control cheaper, faster and more transparent, while narrowing the space for fake seed. Seed companies would then be encouraged to release more new improved varieties, and ultimately accelerate our research impact for African farmers.

A new study explores how conservation agriculture in southern Africa supports spider populations and diversity in fields, which could help mitigate pest damage and potentially lead to higher yields for farmers. According to the Food and Agriculture Organization of the United Nations (FAO), herbivorous insects such as aphids, caterpillars and weevils destroy about one fifth of the world’s total crop production each year. Spiders can help keep voracious pests in-check, but conventional farming practices (e.g. tilling, crop residue removal and monoculture) can harm or drastically reduce these beneficial bio-control agents.
There are more than 45,000 identified spider species around the world. From glaciers to tropical rainforests, they inhabit every terrestrial ecosystem on earth. Some can even live in tidal zones, and at least one species inhabits fresh water. While we tend to associate spiders with webs, only about 50 percent of the species catch their prey this way; the rest hunt on plants, on the ground or below it, using a variety of tactics such as stalking, stabbing, crushing – even seduction.
Although spiders have been around for 300 million years, some species are at risk of extinction due to habitat loss and fragmentation. Drastic reductions in vegetation – whether from a new parking lot or a tilled field – removes the food source that attracts their prey. Bare ground exposes their nesting sites and themselves, which makes it harder to hunt and easier to be hunted by birds and small mammals.
At the Chinhoyi University of Technology experimental farm in Zimbabwe, a team of researchers aimed to determine the response of spiders under different agricultural practices. Conventional farmers often prepare their fields for planting by physically breaking up and inverting the top 6-10 inches of soil. This practice of ploughing prepares a fine soil tilth, which makes it easier to plant; it breaks up and buries weeds, and reduces soil compaction to aerate the soil. But tilling also increases topsoil erosion from wind and water. It accelerates soil carbon decomposition, reduces soil water infiltration and disrupts microorganisms living in the soil, including beneficial insects and spiders.
The researchers conducted two experiments over the 2013/2014 and 2014/2015 cropping seasons to see how tilling, crop residue retention (i.e. leaving stalks and post-harvest organic matter in the field), fertilizer application and weeding affected ground- and plant-wandering spider species. They hypothesized that spider abundance and diversity would increase with lower levels of soil disturbance and more plant cover.
The results showed direct seeding into no-till soil increased the abundance of spiders and the diversity of species. Mulching also showed a positive effect. Contrary to their hypotheses and results from temperate regions, the application of fertilizer and intense weeding did not affect the spider community. The researchers attributed this to the difference in climatic conditions (tropical vs. temperate) of this study in southern Africa.
“Often the government’s and farmer’s immediate reaction to a crop pest issue is to apply a pesticide, but we can make use of biological control agents, which may be cheaper and less damaging for the environment,” says Christian Thierfelder, a co-author of the study. Thierfelder is a cropping systems agronomist and conservation agriculture specialist with the International Maize and Wheat Improvement Center (CIMMYT) with long-term experience in sustainable intensification.
“Spiders, ants and beetles all do a really good job with little or no cost to the farmer,” he adds. “For us, it’s quite fascinating to see simple agronomic practices to affect and control crop pests. This also provides new avenues of dealing with the fall armyworm, an invasive species which has devastated crops across the majority of sub-Saharan Africa countries.”
A robust number of studies from Europe, Australia and North America have shown the link between conservation agriculture and biodiversity, but Thierfelder says that research on biodiversity in agronomic systems is relatively new in southern Africa. While the study in Zimbabwe helps fill this gap, more research is needed to show the connection between the abundance of spiders, beetles and ants with the suppression of insect pest activity.
This research was jointly funded by Chinhoyi University of Technology (CUT) and the German Academic Exchange Program (DAAD). The CGIAR Research Program on Maize (MAIZE) supported this study through Christian Thierfelder’s contributions.

Ethiopia is Africa’s third largest producer of maize, after Nigeria and South Africa. Although the country produces around 6.5 million tons annually, the national average maize yield is relatively low at 3.5 tons compared to the attainable yield of 8.5 tons. This high yield gap — the difference between attainable and actual yields — can be attributed to a number of factors, including crop varieties used, farm management practices, and plant density.
The Taking Maize Agronomy to Scale (TAMASA) project aims to narrow maize yield gaps in Ethiopia, Nigeria and Tanzania through the development and scaling out of decision-support tools, which provide site-specific recommendations based on information held in crop and soil databases collected from each country. These help farmers to make decisions based on more accurate variety and fertilizer recommendations, and can contribute to improving maize production and productivity.
One such tool is Nutrient Expert, a free, interactive computer-based application. It can rapidly provide nutrient recommendations for individual farmers’ fields in the absence of soil-testing data. The tool was developed by the International Plant Nutrition Institute in collaboration with the International Maize and Wheat Improvement Center (CIMMYT), the International Institute of Tropical Agriculture (IITA), and research and extension service providers.

In Ethiopia, regional fertilizer recommendations are widely used, but soil fertility management practices can vary greatly from village to village and even between individual farmers. This can make it difficult for farmers or extension agents to receive accurate information tailored specifically to their needs. Nutrient Expert fills this gap by incorporating information on available fertilizer blends and giving customized recommendations for individual fields or larger areas, using information on current farmer practices, field history and local conditions. It can also provide advice on improved crop management practices such as planting density and weeding, thereby helping farmers to maximize net returns on their investment in fertilizer.
Data calibration was based on the results of 700 multi-location nutrient omission trials conducted in major maize production areas in Ethiopia, Nigeria and Tanzania. These trials were designed as a diagnostic tool to establish which macro-nutrients are limiting maize growth and yield, and determine other possible constraints.
In Ethiopia, CIMMYT scientists working for the TAMASA project conducted nutrient omission trials on 88 farmer fields in Jimma, Bako and the Central Rift Valley in 2015 to produce a version of Nutrient Expert suitable for the country. Researchers trialed the app on six maize-belt districts in Oromia the following year, in which Nutrient Expert recommendations were compared with soil-test based and regional ones.
Researchers found that though the app recommended lower amounts of phosphorus and potassium fertilizer, overall maize yields were comparable to those in other test sites. In Ethiopia, this reduction in the use of NPK fertilizer resulted in an investment saving of roughly 80 dollars per hectare.
Results from Nutrient Expert trials in Ethiopia, Nigeria and Tanzania showed improved yields, fertilizer-use efficiency and increased profits, and the app has since been successfully adapted for use in developing fertilizer recommendations that address a wide variety of soil and climatic conditions in each of the target countries.
The World Bank’s 2016 Digital Dividends report states that we are currently “in the midst of the greatest information and communications revolution in human history.” This shifting digital landscape has significant implications for the ways in which stakeholders in the agricultural sector generate, access and use data. Amidst Africa’s burgeoning technology scene, CIMMYT’s TAMASA project demonstrates the transformative power of harnessing ICTs for agricultural development.

Maize is the most important staple food crop in sub-Saharan Africa, providing food security and a source of income to more than 200 million households. Nonetheless, maize yields in this region rank among the lowest worldwide.
The International Maize and Wheat Improvement Center (CIMMYT) launched the International Maize Improvement Consortium for Africa (IMIC-Africa) in May 2018, to better engage with a committed set of partners from the public and private sector, and to achieve enhanced maize yields in Africa.
Members of IMIC-Africa share a vision: meeting the challenges of maize production by scaling out and fully exploiting the potential of improved climate-resilient and stress-tolerant varieties in sub-Saharan Africa.
Cultivated on over 35 million hectares of typically rainfed land across sub-Saharan Africa, maize is subject to the vagaries of climate, suffering occasional to frequent drought stress. Other regional challenges include poor soil quality, characterized by nitrogen deficiency, and the ongoing threat of transboundary pathogens and pests, such as the voracious fall armyworm. In addition, farmers generally have inadequate access to improved seed that could help them achieve higher yields.
Although the challenges are complex, the effective use of improved, climate-resilient and multiple-stress-tolerant maize varieties has achieved tangible results in this region. Elite drought-tolerant (DT) maize hybrids developed by CIMMYT have demonstrated at least 25-30 percent grain yield advantage over non-DT maize varieties in sub-Saharan Africa under drought stress. CIMMYT has also derived elite heat-tolerant maize hybrids for sub-Saharan Africa, and during the recent outbreak of maize lethal necrosis (MLN), the rapid development and deployment of elite MLN-resistant hybrids was instrumental in the containment of this threat to eastern Africa.
Modelled on its successful counterpart initiatives in Asia (IMIC-Asia) and Latin America (IMIC-LatAm), there is hope that IMIC-Africa will follow a similar pattern of success.
The consortium is comprised of a diverse array of member institutions, including seed companies, national programs and foundations.
Its key objective is to enhance members’ capacity for germplasm development in their own breeding programs through provision of early generation or advanced maize lines. The subsequent multi-location testing of elite pre-commercial maize hybrids throughout sub-Saharan Africa by members will serve to identify products that can advance to commercialization and deployment.
“IMIC-Africa has a growing membership aimed at formalizing the sharing of maize lines under development with public and private maize breeding programs,” said CIMMYT scientist and Africa regional representative Stephen Mugo. “The consortium will also support a vibrant germplasm testing network, offer opportunities for training and cross learning among members, and grant access to other special services offered by CIMMYT including MLN testing, doubled haploid development and molecular quality assurance/quality control.”
The work of the consortium will ultimately benefit the farming community through the targeted development of maize varieties that express traits jointly identified and prioritized by consortium members and that are specifically adapted to the suite of agro-ecologies in sub-Saharan Africa. Traits of relevance include tolerance to abiotic stresses, disease and insect-pest resistance and higher yielding hybrids.
“IMIC-Africa will contribute to food security in Africa by broadening access to and use of stress-tolerant improved maize germplasm as well as strengthening maize breeding programs, thus improving farmers’ access to improved maize varieties,” Mugo explained.
Membership of IMIC-Africa is open to all organized and registered private commercial seed companies, corporations, and organized and registered public agencies or organizations involved in maize crop research and improvement, hybrid seed production or maize seed marketing.

The International Maize and Wheat Improvement Center’s (CIMMYT) gender team joined African Women in Agricultural Research and Development (AWARD) to celebrate its ten years of empowering women with essential skills and knowledge.
The AWARD program advocates for a more gender-responsive agricultural research ecosystem. This is key in driving a more sustainable and inclusive agricultural growth in Africa.
The tenth anniversary event took place in Nairobi on November 29, 2018. Rahma Adam, Gender and Development Scientist, and Kristie Drucza, Gender and Social Inclusion Researcher, showcased the work that CIMMYT’s gender team has done on maize and wheat-based farming systems, not just in Africa, but globally.
“Our participation at AWARD’s anniversary celebrations was not an end in itself, but rather relevant for other organizations within and outside the CGIAR system to learn from CIMMYT’s gender strategic and inclusive research work and draw lessons from it,” Adam said. “We especially appreciate the work done by AWARD, including the leadership trainings offered to promising young women at academic and research institutions, and at international organizations across Africa and beyond.”
Several researchers at CIMMYT have participated in AWARD’s initiatives, both getting mentorship or training and mentoring fellow scientists, thereby nurturing the next crop of researchers and leaders in agriculture.
“These courses are useful in helping one to strike a balance between being a good researcher and a good leader at the workplace and beyond,” Adam said.
Drucza commented on the leadership training she participated in: “They provide opportunities for leaders (some of whom are heads of research institutes across Africa) to understand common leadership challenges women face, engage in thought-provoking conversations and create lasting networks, among other issues.”

In 2018, Drucza, mentored a gender unit director at the Ethiopian Institute for Agricultural Research (EIAR). “As part of the AWARD program, my mentee attended a leadership development course as well as a scientific writing course. This improved her confidence and skills as a researcher and leader,” Drucza said.
As a beneficiary of the AWARD mentorship program in 2014-2015, Pauline Muindi, a research associate at CIMMYT’s gender unit, honed her communication and public speaking skills, which have proved useful for her work.
“These skills have enabled me to train several seed companies in eastern and southern Africa on the integration of gender in the seed value chains as well as gender integration in the workplace,” she said. Her mentor was a previous AWARD fellow. The program also helped her set realistic yet attainable goals for her career growth. “At CIMMYT, I have an opportunity to learn and gain new experiences, while at the same time build sustainable networks that are important in my professional life.”
The keynote speaker was Ameenah Gurib-Fakim, former president of Mauritius. “Women have a special power to be advocates for themselves and each other. We must become aware of that power and unleash it. Ultimately, it will be for we women to open the doors so that others may live and prosper,” Gurib-Fakim concluded.
For small-scale farmers, mechanization and other appropriate technologies have a big impact in agricultural production and yield. However, they might lack the resources to buy these tools. Hello Tractor is trying to improve this.
Dubbed the “Uber for the farm”, the company’s app easily allows tractor owners to rent their machinery to farmers and includes features that can help enhance a tractor owner’s business and operations. In this episode, we’re talking to Martha Haile, Chief Operations Officer at Hello Tractor, about the company’s success and social innovation in agriculture.
Support for smallholder farmers to trial and select sustainable practices suited to their varying conditions is essential to build resilient farms needed to feed Africa’s soaring population, said economist Paswel Marenya at the Second African Congress on Conservation Agriculture in Johannesburg this October.
Farmers face different agroecological, socioeconomic and institutional environments across Africa. The mounting challenges brought by climate change also vary from place to place. Family farmers are born innovators, with government and industry support they can develop a resilient farming system that works for them, said the researcher from the International Maize and Wheat Improvement Center (CIMMYT).
One of the emerging paradigms of sustainable agriculture resilient to climatic changes is conservation agriculture — defined by minimal soil disturbance, crop residue retention and diversification through crop rotation. Although not a one-size-fits-all approach, it is a promising framework to be applied and adapted to meet farmers’ unique contexts, he said.
“Conservation agriculture’s potential to conserve soils, improve yields and limit environmental impacts makes it one of the elements that should be given prominence in efforts to secure sustainable and resilient farming in Africa,” he told audiences at the conference dedicated to discuss conservation agriculture systems as the sustainable basis for regional food security.
“Research shows that with a network of appropriate support, farmers can access the tools and knowledge to experiment, learn, adapt and adopt these important principles of conservation agriculture,” he said.
“Their farming can thus evolve to practices that have low environmental impacts, diversify their cropping including intercropping maize with legumes, and test affordable machinery for efficient, timely and labor-saving operations. In the end, each farmer and farming community have the ability to tailor a conservation agriculture-based system based on what works best given their unique socioeconomic settings,” said Marenya.
Trialing sustainable practices leads to adoption
Through the project over 235,000 farming households in the region have trialed sustainable practices reporting positive results of improved soil fertility, reduced labor costs, and increased food production and maize yields despite erratic weather, said collaborating investigator Custudio George from the Mozambique Institute of Agricultural Research.
“The majority of these farmers have gone on to adopt their preferred practices throughout their whole farm and now actively promote conservation agriculture to other farmers,” he added
Women undertake the majority of agricultural activities in sub-Saharan Africa. When they are empowered to try sustainable practices they overwhelmingly adopt those technologies identifying them as an economically viable way to overcome challenges and increase household food security, said Maria da Luz Quinhentos, who is an agronomist with the Mozambique Institute of Agricultural Research.

Forming networks to support farmer resilience
The research project took a multidisciplinary approach bringing together sociologists, economists, agronomists and breeders to study how maize-legume conservation agriculture-based farming can best benefit farmers in seven countries; including Ethiopia, Kenya, Malawi, Mozambique, Tanzania and Uganda.
In this vein, the project sought to connect farmers with multi-sector actors across the maize-legume value chain through Innovation platforms. Innovation Platforms, facilitated by SIMLESA, are multi-stakeholder forums connecting farmer groups, agribusiness, government extension, policy makers and researchers with the common goal to increase farm-level food security, productivity and incomes through the promotion of maize-legume intercropping systems.
“Having a network of stakeholders allows farmers to test and adopt conservation agriculture-based techniques without the risk they would have if they tried and failed alone,” said Michael Misiko who studies farmer adoption as part of SIMLESA.
“Farmers form groups to work with governments to gain access to improved seed, learn new farming practices and connect with local agribusinesses to develop markets for their produce,”
“When new problems arise stakeholders in local and regional innovation platforms can diagnose barriers and together identify mutual solutions,” he said.
Researchers and governments learn from innovation platforms and can use results to recommend productive climate-smart practices to other farmers in similar conditions, Misiko added.
Climate-smart agriculture key to achieve Malabo Declaration
The results from SIMLESA provide African governments with evidence to develop policies that achieve the Malabo Declaration to implement resilient farming systems to enhance food security in the face of a growing climate risks, said Marenya.
If these smallholders are to keep up with food demand of a population set to almost double by 2050 while overcoming challenges they need productive and climate-resilient cropping systems.
CIMMYT research identifies that the defining principles of conservation agriculture are critical but alone are not enough to shield farmers from the impacts of climate change. Complementary improvements in economic policies, markets and institutions — including multi-sectoral linkages between smallholder agriculture and the broader economy — are required to make climate-resilient farming systems more functional for smallholder farmers in the short and long term, said Marenya.

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya, will begin its phenotyping (screening/ indexing) cycle of 2019 at the beginning of January 2019 and in other four intervals throughout the year. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.
In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.
MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields.
CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing the risk of MLN on maize production through screening and identifying MLN-resistant germplasm. The MLN screening facility supports countries in sub-Saharan Africa to screen maize germplasm (for hybrid, inbred and open pollinated varieties) against MLN in a quarantined environment.
This is the largest dedicated MLN screening facility in East Africa. Since its inception in 2013, the facility has evaluated more than 180,000 accessions (more than 270,000 rows of maize) from more than 15 multinational and national seed companies and national research programs.
Partners can now plan for annual MLN Phenotyping (Screening / Indexing) during 2019 with the schedule below. The improved and streamlined approach for MLN phenotyping should enable our partners to accelerate breeding programs to improve resistance for Maize MLN for sub-Saharan Africa.
The Ethiopian government announced recently that the country should become wheat self-sufficient over the next four years. Why is boosting domestic wheat production important for this country in the Horn of Africa, and could wheat self-sufficiency be attained in the next four years? The Ethiopian Institute for Agricultural Research (EIAR), with the support of International Maize and Wheat Improvement Center (CIMMYT), gathered agriculture and food experts from the government, research and private sectors on November 23, 2018, to draw the first outlines of this new Ethiopian wheat initiative.
The low-tech domestic wheat farming and price support issue
Despite a record harvest of 4.6 million metric tons in 2017, Ethiopia imported 1.5 million tons of wheat the same year, costing US$600 million. Population growth, continuous economic growth and urbanization over the last decade has led to a rapid change in Ethiopian diets, and the wheat sector cannot keep up with the growing demand for pasta, dabo, ambasha and other Ethiopian breads.
The majority of Ethiopia’s 4.2 million wheat farmers cultivate this cereal on an average of 1.2-hectare holdings, with three quarters produced in Arsi, Bale and Shewa regions. Most prepare the land and sow with draft animal power equipment and few inputs, dependent on erratic rainfall without complementary irrigation. Yields have doubled over the last 15 years and reached 2.7 tons per hectare according to the latest agricultural statistics, but are still far from the yield potential.
According to data from the International Food Policy Research Institute (IFPRI), wheat is preferred by wealthier, urban families, who consume 33 percent more wheat than rural households. Ethiopia needs to rethink its wheat price support system, which does not incentivize farmers and benefits mostly the wealthier, urban consumers. Wheat price support subsidies could, for instance, target bakeries located in poor neighborhoods.
Where to start to boost wheat productivity?

Ethiopia, especially in the highlands, has an optimum environment to grow wheat. But to make significant gains, the wheat sector needs to identify what limiting factors to address first. The Wheat initiative, led by Ethiopia’s Agricultural Transformation Agency (ATA), has targeted 2,000 progressive farmers across 41 woredas (districts) between 2013 and 2018, to promote the use of improved and recommended inputs and better cropping techniques within their communities. A recent IFPRI impact study showed a 14 percent yield increase, almost enough to substitute wheat imports if scaled up across the country. It is, however, far from the doubling of yields expected initially. The study shows that innovations like row planting were not widely adopted because of the additional labor required.
Hans Braun, WHEAT CGIAR research program and CIMMYT’s Global Wheat Program director, believes Ethiopian farmers can achieve self-sufficiency if they have the right seeds, the right agronomy and the right policy support.
One priority is to increase support for wheat improvement research to make wheat farmers more resilient to new diseases and climate shocks. Drought and heat tolerance, rust resistance and high yields even in low-fertility soils are some of the factors sought by wheat farmers.
International collaboration in durum wheat breeding is urgently needed as the area under durum wheat is declining in Ethiopia due to climate change, diseases and farmers switching to more productive and resilient bread wheat varieties. Braun advises that Ethiopia set up a shuttle breeding program with CIMMYT in Mexico, as Kenya did for bread wheat, to develop high-yielding and stress-resistant varieties. Such a shuttle breeding program between Ethiopia and Mexico would quickly benefit Ethiopian durum wheat farmers, aiming at raising their yields similar to those of Mexican farmers in the state of Sonora, who harvest more than 7 tons per hectare under irrigation. This would require a policy reform to facilitate the exchange of durum germplasm between Ethiopia and Mexico, as it is not possible at the moment.
Ethiopia also needs to be equipped to respond quickly to emerging pests and diseases. Five years ago, a new stem rust (TKTTF, also called Digalu race) damaged more than 20,000 hectares of wheat in Arsi and Bale, as Digalu — the popular variety used by local farmers — was sensitive to this new strain. The MARPLE portable rust testing lab, a fast and cost-effective rust surveillance system, is now helping Ethiopian plant health authorities quickly identify new rust strains and take preventive actions to stop new outbreaks.

Invest in soil health, mechanization and gender
In addition to better access to improved seeds and recommended inputs, better agronomic practices are needed. Scaling the use of irrigation would certainly increase wheat yields, but experts warn not to dismiss adequate agronomic research — knowing the optimal water needs of the crop for each agroecological zone — and the underlying drainage system. Otherwise, farmers are at risk of losing their soils forever due to an accumulation of salt.
‘’2.5 billion tons of topsoil are lost forever every year due to erosion. A long-term plan to address soil erosion and low soil fertility should be a priority,” highlights Marco Quinones, adviser at ATA. For instance, large-scale lime application can solve the important issue of acid soils, where wheat does not perform well. But it requires several years before the soil can be reclaimed and visible yield effects can be seen.

Mechanization could also boost Ethiopian wheat production and provide youth with new job opportunities. Recent research showed smallholder farmers can benefit from six promising two-wheel tractor (2WT) technologies. Identifying the right business models and setting up adapted training programs and financial support will help the establishment of viable machinery service providers across the country.
Better gender equity will also contribute significantly to Ethiopia becoming self-sufficient in wheat production. Women farmers, especially female-headed households, do not have the same access to trainings, credit, inputs or opportunities to experiment with new techniques or seed varieties because of gender norms. Gender transformative methodologies, like community conversations, can help identify collective ways to address such inequalities, which cost over one percent of GDP every year.
‘’With one third better seeds, one third good agronomy and one third good policies, Ethiopia will be able to be wheat self-sufficient,” concluded Braun. A National Wheat Taskforce led by EIAR will start implementing a roadmap in the coming days, with the first effects expected for the next planting season in early 2019.
TEXCOCO, Mexico (CIMMYT) — Food security is heavily dependent on seed security. Sustainable seed systems ensure that a variety of quality seeds are available to farming communities at affordable prices. In many developing countries, however, farmers still lack access to the right seeds at the right time.
In the past, governments played a major role in getting improved seed to poor farmers. These days, however, the private sector plays a leading role, often with strong support from governments and NGOs.
“Interventions in formal seed systems in maize have tended to focus on improving the capacity of seed producing companies, which are often locally owned small-scale operations, to produce and distribute quality germplasm,” says Jason Donovan, Senior Economist at International Maize and Wheat Improvement Center (CIMMYT). “These local seed companies are expected to maintain, reproduce and sell seed to underserved farmers. That’s a pretty tall order, especially because private seed businesses themselves are a fairly new thing in many countries.”
Prior to the early 2000s, Donovan explains, many seed businesses were partially or wholly state-owned. In Mexico, for example, the Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) produced seed and supplied it to a market-oriented entity which was responsible for distribution. “What we’re seeing now is locally owned private seed businesses carving out their space in the maize seed market, sometimes in direct competition with multinational seed companies,” he says. In Mexico, around 80 locally owned maize seed producing businesses currently exist, most of which have been involved in CIMMYT’s MasAgro Maize project. These are mostly small businesses selling between 150,000 and 500,000 kg of hybrid maize per year.
In the following Q&A, Donovan discusses new directions in research on value chains, the challenges facing private seed companies, and how new studies could help understand their capacities and needs.

How does research on markets and value chains contribute to CIMMYT’s mission?
We’re interested in the people, businesses and organizations that influence improved maize and wheat seed adoption, production, and the availability and quality of maize and wheat-based foods. This focus perfectly complements the efforts of those in CIMMYT and elsewhere working to improve seed quality and increase maize and wheat productivity in the developing world.
We are also interested in the nutrition and diets of urban and rural consumers. Much of the work around improved diets has centered on understanding fruit and vegetable consumption and options to stimulate greater consumption of these foods. While there are good reasons to include those food groups, the reality is that those aren’t the segments of the food market that are immediately available to or able to feed the masses. Processed maize and wheat, however, are rapidly growing in popularity in both rural and urban areas because that’s what people want and need to eat first. So the question becomes, how can governments, NGOs and others promote the consumption of healthier processed wheat and maize products in places where incomes are growing and tastes are changing?
This year, CIMMYT started a new area of research in collaboration with A4NH, looking at the availability of processed maize and wheat products in Mexico City — one of the world’s largest cities. We’re working in collaboration with researchers form the National Institute of Public Health to find out what types of wheat- and maize-based products the food industry is selling, to whom, and at what cost. At the end of the day, we want to better understand the variation in access to healthier wheat- and maize-based foods across differences in purchasing power. Part of that involves looking at what processed products are available in different neighborhoods and thinking about the dietary implications of that.
Your team has also recently started looking at formal seed systems in various locations. What direction is the research taking so far?
Our team’s current priority is to advance learning around the private sector’s role in scaling improved maize varieties. We are engaged with three large projects: MasAgro Maize in Mexico, Stress Tolerant Maize for Africa (STMA) and the Nepal Seed and Fertilizer Project (NSFP). We are looking to shed light on the productive and marketing capacities of the privately owned seed producing businesses and their ability to get more seed to more farmers at a lower cost. This implies a better understanding of options to better link seed demand and supply, and the business models that link seed companies with agro-dealers, seed producing farmers, and seed consumers.
We are also looking at the role of agro-dealers — shops that sell agricultural inputs and services (including seed) to farmers — in scaling improved maize seed.
At the end of the day, we want to provide evidence-based recommendations for future interventions in seed sectors that achieve even more impact with fewer resources.

This research is still in its initial stages, but do you already have an idea of what some of the key limiting factors are?
I think one of the main challenges facing small-scale seed producing businesses is the considerable expense entailed in simultaneously building their productive capacities and their market share. Many businesses simply don’t have a lot of capital. There’s also a lack of access to specialized business support.
In Mexico, for example, a lot of people in the industry are actually ex-breeders from government agencies, so they’re very familiar with the seed production process, but less so with options for building viable businesses and growing markets for new varieties of seed.
This is a critical issue if we expect locally owned seed businesses to be the primary vehicle by which improved seeds are delivered to farmers at scale. We’re currently in the assessment phase, examining what the challenges and capacities are, and hopefully this information will feed into new approaches to designing our interventions.
Is the study being replicated in other regions as well?
Yes, in East Africa, under the Stress Tolerant Maize for Africa (STMA) project. We’re working with seed producing businesses and agro-dealers in Ethiopia, Kenya, Tanzania, and Uganda to understand their strategies, capacities, and needs in terms of providing improved seed to more farmers. We’re using the same basic research design in Mexico, and there is also ongoing work in the Nepal Seed and Fertilizer Project. Given that we are a fairly small team within CIMMYT, comparable cross-regional research is one way to punch above our weight.
Why is this research timely or important?
The research is critical as CIMMYT’s impact relies, in part, on partnerships. In the case of improved maize seed, that revolves around viable seed businesses.
Although critical, no one else is actually engaged in this type of seed sector research. There have been a number of studies on seed production, seed systems and the adoption of improved seed by poor farmers. A few have focused on the emergence of the private sector in formal seed systems and the implications for seed systems development, but most have been pretty broad, examining the overall business environment in which these companies operate but not much beyond that. We’re trying to deepen the discussion. While we don’t expect to have all the answers at the end of this study, we hope we can shift the conversation about options for better support to seed companies and agro-dealers.

NAIROBI, Kenya (CIMMYT) — The CIMMYT family mourns the demise and honors the valuable contributions of Rwandan crop researcher Theodore Assimwe, who died on November 11, 2018.
An active and dedicated CIMMYT partner and one of eastern Africa’s most promising agricultural scientists, Assimwe was instrumental in Rwanda’s response to Maize Lethal Necrosis (MLN), coordinating pathogen surveillance and characterization and a key project for integrated management of the disease.
He was a pillar of the Rwanda Agriculture Board (RAB), with a well-recognized research track record in maize, cassava, and sweet potato. His capacity-building activities, together with those of CIMMYT, fostered the pursuit of advanced studies by numerous research colleagues.
His passion, commitment, and scientific rigor gained the respect of agricultural researchers, national plant protection organizations, and many other partners, including members of the global scientific community.
The CIMMYT community respectfully extends its sympathies and wishes for peace to the family of Assimwe.
NAIROBI, Kenya (CIMMYT) — Smallholder farmers in sub-Saharan Africa lose up to a third of their grain after harvest because they often use poor grain storage technologies and ineffective drying practices. Staples like maize stored on-farm are exposed to infestation by insects and fungi. These can lead to contamination with mycotoxins, in particular aflatoxins, poisonous food toxins produced by Aspergillus fungi.
At high doses, aflatoxins can kill. Prolonged exposure to aflatoxins can impact consumers’ health, suppressing immune systems, hindering child growth and even causing liver cancer. Kenya is a particular hotspot for aflatoxins, as regular studies show widespread contamination along the food chain, from maize grain to milk and meat.
Preliminary findings of a study by USAID-funded Feed the Future Innovation Lab for Food Processing and Post-Harvest Handling (FPL) suggest that innovative low-cost grain drying and storage technologies such as hermetic bags and hygrometers could prevent post-harvest crop losses and harmful aflatoxin contamination.
The initial results were shared at a workshop in Nairobi on October 25, 2018, as part of the FPL project, which aims to develop and disseminate affordable and effective post-harvest technologies suited to the African smallholder farmer. This project is a collaboration between the International Maize and Wheat Improvement Center (CIMMYT), Kenya Agricultural & Livestock Research Organization (KALRO) and Purdue University.
A study conducted between May 2017 and May 2018 in Kiboko, Kenya, compared the performance of various hermetic storage containers and bags by different manufacturers with farmers’ usual storage practices. Researchers measured maize grain quality parameters such as grain damage, weight loss in storage, fungal growth and mycotoxins, food quality and seed germination. The results showed hermetic bags were highly effective in averting grain loss for up to one year.
“If these bags are sealed properly, oxygen cannot get in or out. This creates an anaerobic environment that suffocates grain-damaging insects and prevents fungi from growing” says CIMMYT economist Hugo De Groote.
Making hermetic storage more accessible
The Africa Technical Research Center (ATRC) is involved in the development of some of the hermetic bags that were tested during the study. ATRC director Johnson Odera noted that most of the insect infestations start in the field. “When the farmer harvests and transports the maize home, the grain is already infested,” Odera explained. “The damage can be extensive depending on the level of infestation. One of the ways to minimize the losses, while keeping the food safe for consumption is to use hermetic bags”.
These bags, however, remain largely unavailable to smallholder farmers, according to the study. This is mainly due to farmers’ low awareness levels and the high cost of hermetic bags. Unlike normal storage bags that cost about $0.7 each, hermetic bags retail for $2 to $2.5.
A second study, conducted with maize producers and traders in Kakamega, western Kenya, suggests that dropping prices by 20 percent had the potential to increase sales by 88 percent.
This study further suggested that farmers can benefit a lot from using low-cost hygrometers to accurately measure moisture content in maize. Grain is quickly spoiled by fungi contamination if it is not dry enough when stored. One or two percent lower moisture levels can make a big difference in reducing aflatoxin contamination.
“Farmers could put maize grain samples in a plastic bag and insert low-cost hygrometers to read moisture content after temperature is stabilized in 15 minutes,” says Purdue University professor Jacob Ricker-Gilbert. “They then know if their grain is safe enough for storage or not. However, standard hygrometers cost around $100, which is out of reach for many small farmers.”
Purdue University, CIMMYT and KALRO conducted a market survey in 2017 among maize farmers and traders in Kenya to assess their willingness to buy low-cost hygrometers. The survey found that farmers were willing to pay an average price of $1.21 for a hygrometer, while traders said they would buy at $1.16 each. The project was able to get cheap and reliable hygrometers at less than one dollar, opening the door for possible commercialization. One company, Bell Industries, has started to market the devices as a pilot.
Raising farmers and policymakers’ awareness on appropriate storage and drying technologies is now a priority for scientists working on the FPL project, which will hopefully lead to less maize spoiled and better food safety.
NJORO, Kenya (CIMMYT) — The International Maize and Wheat Improvement Center (CIMMYT), in collaboration with Kenya Agricultural & Livestock Research Organization (KALRO) and Cornell University, recently trained 29 scientists from 13 countries on wheat rust disease diagnosis and management techniques, as well as innovative wheat breeding practices. The training, part of the Delivering Genetic Gains in Wheat (DGGW) project, took place on October 1-9, 2018, at the KALRO research station in Njoro, Kenya, where CIMMYT’s wheat breeding and rust screening facility is located.
More than 200 scientists have increased their capacity at these annual trainings since CIMMYT started organizing them ten years ago. The trainings focus particularly on studying resistance to black (stem) rust, yellow (stripe) rust and brown (leaf) rust. Future wheat champions in national agricultural research systems (NARS) get new skills on innovative and cost-effective wheat breeding. These trainings are also a chance for CIMMYT’s Global Wheat Program to establish new partnerships and to collaborate on emerging challenges related to wheat breeding in different farming regions.
“The focus of this year’s event was to train the scientists on how to identify and record notes for stem rust occurrences and how to evaluate wheat material in the field, to better understand how wheat rust pathogens keep evolving,” said Mandeep Randhawa, wheat breeder and wheat rust pathologist at CIMMYT.

Despite its importance for global food security and nutrition, wheat remains susceptible to endemic and highly destructive rust diseases which can lead to 60-100 percent yield losses. Developing and distributing rust resistant wheat varieties is regarded as the most cost-effective and eco-friendly control measure, especially in developing countries, where the majority are resource-poor smallholder farmers with no access to fungicides to control the disease.
As a global leader in wheat and maize breeding systems, CIMMYT has sustained efforts to develop high-yielding, disease-resistant and stress-tolerant varieties. In partnership with KALRO, CIMMYT identified and released over 15 commercial wheat varieties since the establishment of the stem rust screening facility in Njoro in 2008. Despite the appearance of new devastating strains of stem rust over the period, most of these released wheat varieties are high-yielding with stem rust resistance, according to Randhawa.
“Adequate management practices, including timely planting and application of right fungicides, have kept some of the high-yielding varieties such as Kenya Korongo and Eagle10 in production,” Randhawa explained.
Several high-yielding rust resistant wheat lines are in pipeline for national evaluation to release as wheat varieties in Kenya, he said.
The development of a portable, real-time diagnostics tool for wheat yellow rust, namely the Mobile and Real-time Plant DisEase Diagnostics (MARPLE) was another breakthrough in identifying and combating wheat rust. This mobile plant health diagnosis tool helps identify rust strains in three days instead of months. This is a game changer for the wheat sector, as rust control measures could be deployed before new rust becomes a large-scale epidemic. Led by senior scientist David Hodson, MARPLE is the result of the collaboration between CIMMYT, the Ethiopian Institute of Agricultural Research (EIAR) and the John Innes Centre. There are plans to scale up this innovation in Ethiopia, where it is expected to provide five million wheat farmers a lifeline to control wheat yellow rust.
At the training, participants such as Zafar Ziyaev from Uzbekistan, were glad to gain deeper understanding on how to use modern tools for rust surveillance and the control measures. Others acknowledged the importance of sensitizing and supporting farmers to grow rust-resistant wheat varieties.
Emeritus Professor Robert McIntosh, one of the trainers from the Plant Breeding Institute at the University of Sydney, acknowledged the need for wheat scientists to remain vigilant on rust outbreaks globally and the evolving nature of the pathogens.
“As rust pathogens spread from country to country and region to region, such trainings allow national scientists to learn about the need for constant awareness, the basic principles of epidemiology and genetics that provide the basis of breeding for durable resistance, and what the Njoro rust testing platform can offer to the NARS,” McIntosh said.
On October 22, David Campbell, CEO of Mediae, and his team presented their TV and digital education and development programs to International Maize and Wheat Improvement Center (CIMMYT) staff in Nairobi, Kenya. Mediae is a media company producing the iconic Shamba Shape Up, a weekly farming education TV series watched in Kenya, Uganda and Tanzania.
The purpose of the meeting was to explore the possibility of partnership between CIMMYT and Mediae. Farmer education programs like Shamba Shape Up can showcase CIMMYT’s innovations to millions of farmers. Better awareness could lead to increased adoption of innovations and enhance household incomes, as well as food and nutritional security.
Other education and extension programs include Shamba Chef, which targets women with information about nutrition and family finance, and iShamba,an information service that provides over 350,000 farmers with information on market prices, the weather forecast and tips on crop and animal production.
Since 2013,Shamba Shape Up has run weekly episodes in English and Swahili on Kenya’s Citizen TV, reaching an estimated at 3.5 million people, 70 percent of whom live in rural areas. This “edutainment” program highlights challenges smallholders face in their farming activities. Farm advisories range from crop production, animal husbandry and soil fertility, to seeds, pests and diseases, and climate change adaptation strategies. Usually, highlighted farmers narrate the issues on their farm to a TV presenter while an expert from the private or non-profit sector offers advice on remedial measures. This helps the farmer to improve their productivity and livelihood. Campbell believes that “a mix of entertainment and research elements have enabled the program to remain relevant and sustainably serve large, diverse audiences.”

In April 2014, CIMMYT and the African Agricultural Technology Foundation (AATF) were featured in a Shamba Shape Up episode. The broadcast showcased a maize farmer whose crop production had been devastated by striga, a parasitic weed that had infested over 300,000 hectares of maize in western Kenya. Farmers were advised to plant IR maize, a new herbicide-coated seed variety that is immune to striga and can kill it, and this helped to stop the spread of striga in the region. A more recent episode featuring CIMMYT’s efforts to instill sustainable intensification practices among farmers was aired in February 2018.
Campbell and his team have observed that while millions of farmers enjoy their education programs, many fail to continue applying expert advice on good agricultural practices, such as conservation farming, on their own farms. One particular challenge and area with scope for collaboration is to conduct proper impact evaluation of education programs on farming practices changes and livelihoods.
