Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

Tracing maize landraces, 50 years later

Written by Carolyn Cowan on . Posted in Features. 2 Comments on Tracing maize landraces, 50 years later

Maize is more than a crop in Mexico. While it provides food, feed and raw materials, it is also a bloodline running through the generations, connecting Mexico’s people with their past.

The fascinating diversity of maize in Mexico is rooted in its cultural and biological legacy as the center of origin of maize. Landraces, which are maize varieties that have been cultivated and subjected to selection by farmers for generations, retaining a distinct identity and lacking formal crop improvement, provide the basis of this diversity.

As with any cultural legacy, the cultivation of maize landraces can be lost with the passage of time as farmers adapt to changing markets and generational shifts take place.

Doctoral candidate Denisse McLean-Rodríguez, from the Sant’Anna School of Advanced Studies in Italy, and researchers from the International Maize and Wheat Improvement Center (CIMMYT) have undertaken a new study that traces the conservation and abandonment of maize landraces over the last 50 years in Morelos, Mexico’s second smallest state.

The study is based on a collection of 93 maize landrace samples, collected by Ángel Kato as a research assistant back in 1966-67 and stored in CIMMYT’s Maize Germplasm Bank. Researchers traced the 66 families in Morelos who donated the samples and explored the reasons why they abandoned or conserved their landraces.

Tracing landrace abandonment

In six cases, researchers were able to interview the original farmers who donated the samples to CIMMYT. In other cases, they interviewed their family members, most frequently the sons or daughters, or alternatively their grandchildren, siblings, nephews or widows.

The study reveals that maize landrace cultivation has diminished significantly within the families. Only 13 of the 66 families are still cultivating the same maize seed lots as in 1966-67 and there was consensus that the current social, economic and physical environments are unfavorable for landrace cultivation.

Among the reasons for abandonment are changes in maize cultivation technologies, shifting markets for maize and other crops, policy changes, shifting cultural preferences, urbanization and climate change.

“By finding out about landrace continuity in farmers’ fields and the factors driving change, we were able to better understand the context in which these landraces are currently cultivated,” said McLean-Rodríguez. “Our study also allowed us to evaluate the importance of ex situ conservation in facilities like CIMMYT’s Germplasm Bank.”

Maize biodiversity conservation

Maize landraces can be conserved “in situ” in farmers’ fields and “ex situ” in a protected space such as a germplasm bank or community seed bank.

“These conservation strategies are complementary,” explained McLean-Rodríguez. “Ex situ conservation helps to secure landraces in case of unpredictable conditions that threaten their conservation in the field, while in situ cultivation allows the processes that generated maize’s diversity to continue, allowing the emergence of mutations and the evolution of new potentially beneficial traits.”

The loss of landraces in farmers’ fields over 50 years emphasizes the importance of ex situ conservation. CIMMYT’s Maize Germplasm Bank holds 28,000 samples of maize and its wild relatives from 88 countries, spanning collections dating back to 1943. Safeguarded seed stored in the Germplasm Bank is protected from crises or natural disasters, and is available for breeding and research. Traits found in landraces can be incorporated into new varieties to address some of the world’s most pressing agriculture challenges like changing climates, emerging pests and disease, and malnutrition.

McLean-Rodríguez recalls an aspect of the study that she found particularly rewarding: “Many of the families who had lost their landrace for one reason or another were interested in receiving back samples of their maize from the CIMMYT Germplasm Bank. Some were interested due to personal value, while others were more interested in the productive value. They were very happy to retrieve their maize from the Germplasm Bank, and it would be very interesting to learn whether the repatriated seed is cultivated in the future.”

A family tradition

One of the families to take part in the study was farmer Roque Juarez Ramirez and his wife, Ventura Oliveros Garcia, whose father was one of the donor farmers from Morelos. “I was so happy to hear the name of my father, [Santos Oliveros],” recalls Oliveros, remembering the moment McLean-RodrĂ­guez contacted her. “He had always been a maize farmer, as in his day they didn’t cultivate anything else. He planted on his communal village land [ejido] and he was always able to harvest a lot of maize, many ears. He planted an heirloom variety of maize that we called arribeño, or marceño, because it was always planted in March.”

Juarez senses his responsibility as a maize farmer: “I feel that the importance [of maize farming] is not small, but big. We are not talking about keeping 10 or 20 people alive; we have to feed a whole country of people who eat and drink, apart from providing for our families. We, the farmers, generate the food.”

Filling vessels of champurrado, a Mexican maize-based sweet drink, and presenting samples of the family’s staple maize — maíz colorado and the Ancho landrace — Oliveros describes what maize means to her: “Maize is very important to my family and me because it is our main source of food, for both humans and animals. We use our maize variety to make pozole, tortillas, tamales, atole, quesadillas, picadas and many other foods.”

The Juarez-Oliveros family substituted the Ancho seed lot from Olivero’s father with another seed lot from the Ancho landrace obtained from her husband’s family. The Ancho landrace is used to make pozole, and continues to be widely cultivated in some municipalities of Morelos, including Totolapan, where the family resides. However, researchers found other landraces present in the 1966-67 collection, such as Pepitilla, were harder to trace 50 years later.

The study shows that landrace abandonment is common when farming passed from one generation to the next. Older farmers were attached to their landraces and continued cultivating them, even in the face of pressing reasons to change or replace them. When the younger generations take over farm management, these landraces are often abandoned.

Nonetheless, young farmers still value the cultural and culinary importance of landraces. “Maize has an important traditional and cultural significance, and is fundamental to our economy,” said Isaac Juarez Oliveros, son of Roque and Ventura. “I have been planting [maize landraces] since I was around 15 to 20 years old. I got my maize seed from my parents. I believe it is important for families to keep planting their maize, as it has become tradition passed down through many generations.”

The legacy for future generations

Global food security depends on the maintenance of high genetic biodiversity in such key staple food crops as maize. Understanding the causes of landrace abandonment can help to develop effective landrace conservation strategies. The authors suggest that niches for landrace conservation and even expansion can be supported in the same manner that niches have been created for improved maize and other commercial crops. Meanwhile, management of genetic resources is vital, both in the field and in germplasm banks, especially in developing countries where broader diversity exists.

For Oliveros, it is a matter of family legacy: “It means a lot to me that [my family’s seed] was preserved because it has allowed my family’s maize and my father’s memory to stay alive.”

“Farmers who cultivate landraces are providing an invaluable global public service,” state the authors of the study. “It will be key to encourage maize landrace cultivation in younger farmers. Tapping into the conservation potential of the current generation of farmers is an opportunity we should not miss.”

The research team behind the MARPLE (Mobile And Real-time PLant disEase) diagnostic kit won the International Impact category of the Innovator of the Year 2019 Awards, sponsored by the United Kingdom’s Biotechnology and Biological Sciences Research Council (BBSRC).

The team — Diane Saunders of the John Innes Centre (JIC), Dave Hodson of the International Maize and Wheat Improvement Center (CIMMYT) and Tadessa Daba of the Ethiopian Institute for Agricultural Research (EIAR) — was presented with the award at an event at the London Science Museum on May 15, 2019. In the audience were leading figures from the worlds of investment, industry, government, charity and academia, including the U.K.’s Minister of State for Universities, Science, Research and Innovation, Chris Skidmore.

The BBSRC Innovator of the Year awards, now in their 11th year, recognize and support individuals or teams who have taken discoveries in bioscience and translated them to deliver impact. Reflecting the breadth of research that BBSRC supports, they are awarded in four categories of impact: commercial, societal, international and early career. Daba, Hodson and Saunders were among a select group of 12 finalists competing for the four prestigious awards. In addition to international recognition, they received ÂŁ10,000 (about $13,000).

“I am delighted that this work has been recognized,” Hodson said. “Wheat rusts are a global threat to agriculture and to the livelihoods of farmers in developing countries such as Ethiopia. MARPLE diagnostics puts state-of-the-art, rapid diagnostic results in the hands of those best placed to respond: researchers on the ground, local government and farmers.”

On-the-ground diagnostics

The MARPLE diagnostic kit is the first operational system in the world using nanopore sequence technology for rapid diagnostics and surveillance of complex fungal pathogens in the field.

In its initial work in Ethiopia, the suitcase-sized field test kit has positioned the country — one of the region’s top wheat producers — as a world leader in pathogen diagnostics and forecasting. Generating results within 48 hours of field sampling, the kit represents a revolution in plant disease diagnostics. Its use will have far-reaching implications for how plant health threats are identified and tracked into the future.

MARPLE is designed to run at a field site without constant electricity and with the varying temperatures of the field.

“This means we can truly take the lab to the field,” explained Saunders. “Perhaps more importantly though, it means that smaller, less-resourced labs can drive their own research without having to rely on a handful of large, well-resourced labs and sophisticated expertise in different countries.”

In a recent interview with JIC, EIAR Director Tadessa Daba said, “we want to see this project being used on the ground, to show farmers and the nation this technology works.”

Sustaining the production and demand of Quality Protein Maize in Ethiopia

Written by JĂ©rĂŽme Bossuet on . Posted in News.

The International Maize and Wheat Improvement Center (CIMMYT) and Ethiopia’s Ministry of Agriculture held a workshop on March 23, 2019, with the main stakeholders of the agricultural research and seed sectors to discuss how Quality Protein Maize (QPM) production and demand could be expanded, to ensure lasting nutrition benefits for consumers and incomes for farmers.

Maize is the second most cultivated cereal in Ethiopia, with 66% of cereal-farming households cultivating maize on 2.1 million hectares. It is a primary staple food in the major maize-growing areas as well as a source of feed for animals and a raw material for industries. With increasing pressures from climate change and population growth, maize is likely to be key to meeting the challenges of food and income security.

Despite its high productivity, maize grain does not provide balanced protein for human consumption. It is deficient in two essential amino acids, lysine and tryptophan, putting those who consume maize without alternative protein sources at risk of malnutrition and stunted growth and development. Infants and young children are especially at risk. Complementary and alternative sources of protein such as legumes or animal products — meat, eggs and milk – are often inaccessible or unaffordable to the poorest households.

QPM is a type of maize, developed through conventional breeding, that contains nearly twice the amount of tryptophan and lysine compared to common varieties. Research shows that eating QPM can improve quality protein intake among young children and QPM is nutritionally advantageous over conventional maize, especially for families with an undiversified diet dominated by maize.

Since 2012, CIMMYT has been working with the Ethiopian Institute of Agricultural Research (EIAR), the Ministry of Agriculture and other strategic partners like the Ethiopian Public Health Institute (EPHI), Sasakawa Global 2000 (SG2000) and Farm Radio International, to improve food and nutritional security in Ethiopian farming communities through the promotion and expansion of QPM under the Nutritious Maize for Ethiopia (NuME) project. This project built on the achievements of a previous project called Quality Protein Maize Development (QPMD). Both projects were financed by the government of Canada.

Ethiopians are willing to pay for QPM

During the workshop, CIMMYT senior scientist and NuME project leader Adefris Teklewold talked about the favorable conditions that had contributed to the project’s success and which are also grounds for sustainability: government policies and strategies, technical knowledge and technology, and the productive collaboration among partners.

The NuME project operated in 36 woredas, or districts, of the Amhara, Oromia, SNNP and Tigray regions. More than 68% of the target population is now aware of the nutritional benefits of QPM, boosting the demand for the nutritious maize.

Four QPM varieties have been released since the beginning of the project and at least two promising varieties are in the pipeline. Figures show an adoption rate of 11% in the project’s target areas. Today, the main issue to reach out more people is shortage of seed.

Consumers are willing to pay up to 15-20% more for QPM grain compared to non-QPM maize, which can encourage farmers, seed suppliers and other stakeholders to invest on QPM.

The project team trained people in food preparation and organized events to demonstrate the benefits of QPM. One fifth of the 1,788 QPM demonstrations were managed entirely by women. Through demonstrations and blind tastings, people could check that QPM maize did not affect the taste or functional properties of traditional foods like dabo bread or injera flatbread. For instance, they realized that injera using QPM also stayed moist and could be rolled easily. In addition, a recent study on school feeding revealed that dishes made from QPM received wider acceptance.

Beyond the NuME project

Germame Garuma, Director General of Extension at the Ministry of Agriculture, said that “QPM is an important solution to help us improve the nutrition situation in the country.” The Ethiopian government now aims to ensure 10% of the total maize growing area is planted with QPM. Ethiopia has included QPM as a key intervention in national strategies and programs, such as the Agriculture Growth Program-II and the Seqota Declaration.

Garuma called on all government offices at various levels and NGOs working in the agriculture and nutrition sector to continue the promotion of QPM. Workshop participants drew a roadmap with four focus areas: overall coordination, dissemination, technology generation and seed production. With the leadership of the Ministry of Agriculture, more families will be able to improve their diet with QPM in the future.

Dagmo Nour, Project Manager at Global Affairs Canada, expressed interest in engaging further with CIMMYT and its partners to ensure the sustainability and scaling of QPM efforts by addressing critical issues with Ethiopian seed systems.

CIMMYT and GOAL team up to help farmers in Zimbabwe fight fall armyworm

Written by Mary Donovan on . Posted in Press releases.

DUN LAOGHAIRE, Ireland and TEXCOCO, Mexico — Irish humanitarian aid agency GOAL has joined CIMMYT (the International Maize and Wheat Improvement Center) in the fight against fall armyworm, a devastating insect pest that experts say threatens the food security of millions of people in Africa.

The fall armyworm has caused significant damage to maize crops in sub-Saharan Africa since its arrival to the region in 2016.

A study on the impact of the fall armyworm in eastern Zimbabwe reveals that nearly 12 percent of crops are lost annually due to the infestation. And the study states that if the problem spreads throughout the entire country tonnes of grain to the value of $32 million could be lost.

GOAL Zimbabwe has now teamed up with CIMMYT to identify conditions that promote fall armyworm infestation in order to educate farmers on best practices to fight the problem.

Regular weeding, conservation agriculture, use of manure and compost, and ending pumpkin intercropping have been found to help prevent infestation.

Mainassara Zaman-Allah, co-author of the study and abiotic stress phenotyping specialist at CIMMYT said, “Given the limited coverage of the study in terms of area and season, it would be interesting to replicate it all over the country through the involvement of governmental agricultural departments, so that we get the full picture around the fall armyworm problem at a larger scale.”

Gift Mashango from GOAL Zimbabwe, said, “The fall armyworm has further worsened the food security situation of smallholder farmers who are already coping with an ailing economy and climate change. Besides the adverse effects posed to the environment by chemical methods of combating the pest, the smallholder farmer cannot afford to meet the associated costs, hence the need to come up with innovative cost-effective farming systems like climate smart agriculture.”

Book launch: Lead farmers in eastern and southern Africa

Written by Carolyn Cowan on . Posted in News. 1 Comment on Book launch: Lead farmers in eastern and southern Africa

Tackling the challenges of climate change and increasing scarcity of resources like arable land and water requires that farming and food systems around the world undergo fundamental shifts in thinking and practices. A new book draws on experiences of men and women farmers across eastern and southern Africa who have been associated with the Sustainable Intensification of Maize-Legume Systems for Food Security in Eastern and Southern Africa (SIMLESA) project. The inspiring and moving accounts tell the story of how these farmers have bravely embraced change to improve their farming methods and consequently the lives and livelihoods of their families.

The maize-growing regions of southern and eastern Africa face many challenges, including lower than average yields, crop susceptibility to pests and diseases, and abiotic stresses such as droughts that can be frequent and severe. There is also widespread lack of access to high-yielding stress resilient improved seed and other farming innovations, presenting a need for scalable technologies, adapted to farmers’ growing conditions.

Maize is the most important staple crop in the region, feeding more than 200-300 million people across Africa and providing food and income security to millions of smallholder farmers. Prioritization of cost reducing, yield enhancing and resource conserving farming methods is vital to catalyze a shift towards sustainable and resilient maize agri-food systems. Conservation agriculture (CA) is one promising approach.

Launched in 2010, SIMLESA is led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the Australian Center for International Agricultural Research (ACIAR). The project supports farmers and partner organizations to achieve increased food production while minimizing pressure on the environment by using smallholder farmers’ resources more efficiently through CA approaches. SIMLESA is implemented by national agricultural research systems, agribusinesses and farmers in partner countries including, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Tanzania and Uganda.

The farmers’ words in this book drive home the core philosophy of SIMLESA: that critical paradigm shifts in smallholder farming are possible and can lead to positive and potentially lasting impacts.

The candid accounts of the benefits yielded from adopting new practices like CA are a testimony to this idea:  “Now we have seen with our own eyes these new methods are beneficial, and we want to continue what we are doing
.my field is a school where others can learn,” said Maria Gorete, a farmer in Mozambique.

Policy makers and scientists from eastern and southern Africa met in Uganda at a regional forum convened by the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA), on 3-4 May 2019. The forum discussed ways to scale up the learnings of SIMLESA and a joint communique recommending policy actions was signed by the Ministers of Agriculture of the Republic of Burundi, the Republic of the Congo, the Democratic Republic of Congo, the State of Eritrea, the Federal Democratic Republic of Ethiopia, the Republic of Kenya, the Republic of Madagascar,  the Republic of Rwanda, the Republic of South Sudan, the Republic of the Sudan, the United Republic of Tanzania, the Republic of Uganda, the Republic of Malawi and the Republic of Mozambique of the high level Ministerial Panel on Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA).

New role in Nepal is “a dream come true”

Written by Emma Orchardson on . Posted in Features.

Cynthia Carmona will always remember the directive her supervisor gave to a researcher panicked by mounting paperwork: You go and work on the science. We’ll take care of the admin part.

“They already have their hands full with research and building partnership strategies. They shouldn’t have to be concerned about whether or not an invoice has been sent,” she says.

Growing up in the Mexican state of Sonora, Carmona was aware of the International Maize and Wheat Improvement Center’s (CIMMYT) Obregon experimental station from a young age. “It was an organization that I knew existed, but all I knew was that they worked on wheat.”

After studying international relations at Tecnológico de Monterrey in Mexico City, Carmona spent a couple of years working in government and the private sector but she remained on the look-out for global-facing opportunities. Drawn to the opportunity to work with donors, Carmona joined CIMMYT’s Project Management Unit (PMU) six years ago.

“When I first arrived it was more of a grant management unit and we were divided by grant cycle. One person would work on proposals, another on contracts and so on, so you didn’t really get to see the whole process from start to finish.”

The unit has evolved since then, and growing responsibility means that the team is now divided by specialty, from donor relations and resource mobilization to grant management and monitoring and evaluation. “The structure we have now definitely gives you a broader understanding of each project.”

Carmona stresses that even though PMU staff don’t work in the field or in laboratories, they do make significant contributions to project implementation by encouraging smoother processes, alleviating administrative problems and ‘speaking a common language’ between researchers and management. When she took on the role of grant management coordinator, she impressed upon her team the extent to which their action or inaction could affect the projects they support. “Making things happen was my favorite part of the role, and I saw my job as that of an ‘issue solver’.”

Carmona is currently based in Kathmandu, Nepal, where she is serving as interim project manager on CIMMYT’s Cereal Systems Initiative for South Asia (CSISA) project.

“I’m very excited about this new opportunity. CSISA has always been a flagship project for CIMMYT, so when they invited me to help them it was like a dream come true.”

She first visited Nepal in December 2018, where she spent time shadowing the outgoing manager who provided her with an introduction to the country, the region and the project itself.

“It was like a two-week bootcamp. But even though it was intense, I didn’t feel overwhelmed.”

Working in PMU, Carmona explains, provides a solid background for project management and an understanding of how CIMMYT projects work, from start to finish, as well as how to communicate with funders and build shared knowledge by bringing people together, from scientists and researchers to program and service unit staff.

Besides learning about how a project is run on-the-ground, Carmona is most looking forward to gaining field experience while in Nepal. “Talking to farmers and project teams, listening to their experiences and witnessing CIMMYT’s work on-the-ground really gives you a sense of belonging and a connection to our mission.”

Policy outreach to mainstream SIMLESA learning: Q&A with Paswel Marenya

Written by JĂ©rĂŽme Bossuet on . Posted in News. 1 Comment on Policy outreach to mainstream SIMLESA learning: Q&A with Paswel Marenya

The Sustainable Intensification of Maize-Legume Systems for Food Security in Eastern and Southern Africa project (SIMLESA), led by the International Maize and Wheat Improvement Center (CIMMYT), has completed a series of country policy forums. The forums focused on maize-legume intercropping systems, Conservation Agriculture based on Sustainable Intensification (CASI) and other innovations that can help farmers in target countries shift to more sustainable farming practices resulting in better yields and incomes.

Policy makers and scientists from eastern and southern Africa will meet in Uganda at a regional forum convened by the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA), 3-4 May, 2019. The forum will discuss ways to scale up the learnings of SIMLESA.

In the following interview, Paswel Marenya, CIMMYT scientist and SIMLESA leader, reflects on 8 years of project learning, what CASI means for African smallholder farmers, the dialogue between scientists and policy makers and next steps.

Q: What does sustainable intensification of the maize-legume systems mean in the African context? Why is this important for smallholder farmers?

A: Sustainable intensification is the ability to produce more food without having a negative impact on the environment and the natural resource base, but in an economically profitable, and socially and politically acceptable way. In eastern and southern Africa (ESA), maize is the most important staple and the population’s main calorie source. In Kenya, Malawi, Tanzania and Ethiopia annual per capita consumption of maize is around 100, 130, 70 and 50 kg respectively. This important cereal is at the center of nutrition and food security in the countries where SIMLESA has been working.

Legumes and cereals go hand-in-hand. In ESA the majority of agriculture producers – typically over 70 percent – are small farmers who farm on less than 5 hectares of land. Smallholders need sustainable diversification by intercropping maize with legumes. They get their calories from the cereals and derive proteins from the legumes. If they get marketable surplus, legumes are lucrative crops that typically fetch twice the price of maize.

Currently, the average legume yield in ESA is about 0.5 tons per hectare (t/ha). With the practices and the new varieties that SIMLESA tested, legume yield increased by 1-1.5 t/ha. Such significant yield improvement can have a huge impact on household income, food and nutritional security. For maize, the average yield in the region is about 1 t/ha, although in Ethiopia average yield is 2-2.5 t/ha. Using SIMLESA-recommended CASI practices yields of up to 3.5-4 t/ha were achieved in research-managed fields. Under farmer conditions, the yield can increase from 1-1.5 t/ha to about 2-2.5 t/ha.

SIMLESA has enabled farmers to significantly increase the productivity of maize and legumes without undermining soil health, and allowed farmers to become more resilient, especially in the face of erratic and harsh climate conditions.

Integration of small mechanization in CASI practices, particularly in Tanzania, is another positive outcome of SIMLESA. Farm labor tends to fall disproportionately on women and children in traditional systems, so the integration of machinery that can eliminate labor drudgery might alleviate the labor burden away from women.

Q: How did SIMLESA identify the best approaches to improve yields and incomes in a sustainable way in each target country?

A: Africa has not experienced the green revolution that South and Southeast Asia experienced in the 1960s and 1970s, with improved varieties, irrigation and government support. Africa’s heterogenous environment calls for a different approach that is more systems oriented. The integration of disciplines from agronomy, soil science, breeding, economics and social science – including market studies and policy analysis – are part of the approach SIMLESA has used. This interdisciplinary approach is something you seldom see in many projects.

To identify best approaches, SIMLESA has conducted adaptive agronomy research, which involves scientists replicating successful experiments done in agricultural institutes or research stations in farmers’ fields under farmer resources and local conditions.

SIMLESA also promotes the notion of conservation agriculture to shift thinking in farmer practices. Conservation agriculture involves farmers growing maize and legumes in minimally tilled fields, retaining crop residue on fields without burning or discarding and implementing crop diversification.

Q: What are some of the key takeaways from the policy dialogues SIMLESA initiated in the project countries?

A: One of the things we have done in the final year of SIMLESA is policy outreach. Having done all the adaptive agronomy, socio-economic and gender studies, it is time to mainstream the results. One way of doing this is to share specific, concrete results with decision makers and explain the implication of those results to them. To do that, we organized a series of workshops in seven target countries in the region, at both the local and national levels. We shared ideas on what can be done to mainstream SIMLESA in development and research programs and in knowledge systems.

For SIMLESA practices to become the norm, more farmers need to use conservation agriculture systems, adopt improved, drought-tolerant varieties, integrate and improve legume production and where possible, practice crop rotation. At a minimum, they should do optimal and resource-conserving intercropping, conserve crop biomass for extended periods in order to recycle nutrients and organic matter and move away from aggressive tillage.

Across the seven countries, research on CASI practices should continue with proper knowledge systems put in place. Curated agronomy and socio-economic research data are easily accessible to a range of actors – scientists, farmers or agribusinesses – in a repository. Policy recommendations at country level have been summed up in a series of policy briefs.

The need to strengthen the training and mainstreaming of conservation agriculture in the curriculum at the tertiary-education level was stressed in Kenya and Tanzania. Developing the machinery value chain was recommended in Uganda, Tanzania and Mozambique. Such tools as the hoe, jab planter, riplines and the two-wheel tractor are suitable for implementing conservation agriculture practices like planting seed on untilled or minimally tilled land with crop residue. Another suggestion from Uganda, Tanzania and Mozambique was the need to focus on training of technicians who can provide machinery after-sales services and promote machinery hire to help farmers access the basic tools. Incubating businesses in custom hire services, provision of seed capital, and a focus on multi-functional mechanization also featured prominently. Another idea was to support small last-mile agribusinesses such as agro-dealers to aid scaling efforts.

Workshops also highlighted a need for government to work closely with extension services and industry associations to show the benefits of agricultural inputs on a consistent and long-term basis. This can help create markets and therefore the business case for agribusinesses to expand their distribution networks.

Q: How relevant is the issue of indigenous or local knowledge in the implementation and scale up of CASI approaches?

A: CASI principles are compatible with traditional African farming practices, especially the diversification element. African agro-ecologies are not conducive to monocropping as such, especially in areas with poor markets. If you don’t have good linkages with the markets, you will lose out, especially on the nutritional aspects. Where will you, for instance, get your proteins? African indigenous agriculture was a more self-containing system and self-regenerative in the sense that people did fallow farming, there was strong crop-livestock integration and mixed cropping systems.

Q: What are some of the adoption constraints that relate to the implementation or scale-up of CASI approaches?

A: Some of the constraints include the availability of appropriate machinery and suitable weed management. Currently, for weed management, the suggestion is to use herbicides. This is facing resistance in countries such as Kenya and Rwanda owing to the environmental effects of widespread herbicide use. The challenge is to find weed management technologies that minimize or eliminate herbicide use. The other constraint relates to markets. When you succeed in raising legume and maize production, you must find markets for them.

Another constraint concerns educating farmers on implementing the practices in the right way on a large scale. This expensive undertaking requires a public-private sector partnership. To have impact, you need large-scale farmer education and demonstrations.

Q: One of the key constraints is labor intensive activities that are inefficient and time wasting. This can be fixed with access to small mechanization. What are some of the approaches that enable smallholders’ access to farm machinery? How sustainable are these approaches?

A: This is one  area that needs more work. Although machinery was not an integral part of the project design, SIMLESA scientists and national implementers found ways of assimilating machinery testing, including leveraging other CIMMYT projects such as the Farm Mechanization and Conservation Agriculture for Sustainable Intensification project (FACASI), which was a SIMLESA collaborator on the farm mechanization component. Two-wheel tractors and other conservation agriculture machinery that were tested to promote the agronomy that SIMLESA was working on, especially in Tanzania, came from the FACASI project.

Q: SIMLESA stakeholders will gather at the ASARECA regional forum in early May to discuss actionable CASI programs for the public and private sector alike. What do you expect from this regional forum? If there were two or so policy recommendations to give, what would they be?

A: At the forum, we will engage with top-level officials from governments, development organizations and the private sector from ASARECA countries including Mozambique and Malawi. We expect to share the key lessons we learned from SIMLESA. The focus is on how to catalyze paradigm shifts in smallholder agronomy and accelerate institutional change that will enable the technologies to get to scale. We hope to see a communiqué, expressing the acceptance and commitment of the conclusions from the forum, developed and signed. That should serve as a lasting record of the commitments and agreements made at the forum.

Some policy recommendations include creating an enabling environment that provides nationwide CASI demonstration sites for farmers. We are encouraging the government, the private sector and community organizations to join forces and find ways of facilitating the funding for multi-year, long-term CASI demonstration and learning sites. While CASI practices are becoming mainstream in the thinking of business and government leaders, these now need to be specifically be budgeted into various agricultural programs. One key program to promote CASI is retraining extension workers to on new systems of production based on CASI principles so they can facilitate knowledge transfer and help farmers act collectively and engage with markets more effectively.

The fall armyworm, an invasive insect-pest native to the Americas, has caused significant damage to maize crops in sub-Saharan Africa since its arrival to the region in 2016. An integrated approach, including improved agronomic practices, is necessary in order to fight against the invasive caterpillar. However, little is known about the most effective agronomic practices that could control fall armyworm under typical African smallholder conditions. In addition, more information is needed on the impact of fall armyworm on maize yield in Africa, as previous studies have focused on data trials or farmer questionnaires rather than using data from farmer fields. In a new study published by researchers with the International Maize and Wheat Improvement Center (CIMMYT), investigators set out to understand the factors influencing fall armyworm damage and to quantify yield losses due to fall armyworm damage.

The study examined damage in smallholder maize fields in two districts of eastern Zimbabwe. “We estimated the yield losses due to fall armyworm damage at 11.57 percent in the study area. Extrapolated to the whole of Zimbabwe, this would amount to a loss of 200,000 tons of grain, or a value of more than $32 million using the average global price of maize of $163 per ton in 2018,” said Frederic Baudron, cropping systems agronomist at CIMMYT and main author of the study.

Practices such as infrequent weeding or planting on land that had previously been fallow were found to increase fall armyworm damage to maize — most likely because they increased the amount of fall armyworm host plants other than maize. Conversely, practices hypothesized to increase the abundance of natural enemies of fall armyworm — such as minimum and zero tillage or the application of manure and compost — were found to decrease fall armyworm damage. Intercropping with pumpkins was found to increase damage, possibly by offering a shelter to moths or facilitating plant-to-plant migration of the caterpillar. Fall armyworm damage was also higher for some maize varieties over others, pointing to the possibility of selecting for host plant resistance.

“Given the limited coverage of the study in terms of area and season, it would be interesting to replicate it all over the country through the involvement of governmental agricultural departments, so that we get the full picture around the fall armyworm problem at a larger scale,” said Mainassara Zaman-Allah, co-author of the study and abiotic stress phenotyping specialist at CIMMYT.

This study is unique in that it is the first to collect information on agronomic practices that can affect fall armyworm damage using data taken directly from smallholder farmer fields. “Many papers have been written on pest incidence-damage-yield relationships, but with researchers often having control over some of the potential sources of variation,” said Peter Chinwada, TAAT Fall Armyworm Compact Leader at the International Institute of Tropical Agriculture (IITA), another co-author of the study.

“Our study was driven by the desire to determine fall armyworm incidence-damage-yield relationships under typical African smallholder farmer conditions which are characterized by a diversity of cropping systems, planting dates and “pest management practices” that may have been adopted for purposes which have nothing to do with managing pests. Unravelling such relationships therefore requires not only institutional collaboration, but the meeting of minds of scientists from diverse disciplines.”

The results of the study suggest that several practices could be promoted to control fall armyworm in its new home of Africa. “Farmers have already been informed of the results by their extension agents; the NGO GOAL, present in Zimbabwe, shared the findings,” Baudron said. “The next step is to test some of the recommendations suggested in the paper to control fall armyworm such as good weed management, conservation agriculture, use of manure and compost, and stopping pumpkin intercropping. These approaches will need to be refined.”
