Post-harvest losses — which can range between 10-20% in major cereals — cause not only the loss of economic value of the food produced, but also the waste of scarce resources such as labor, land, and water, as well as non-renewable resources such as fertilizer and energy.
“High postharvest losses imply reduced grain yield, but with the same total greenhouse gas emission,” says Rabé Yahaya, a CIM/GIZ Integrated Expert working at the International Maize and Wheat Improvement Center (CIMMYT). “Reducing these losses reduces the yield-scaled global warming potential — total greenhouse gas emission per kilogram of grain — and contributes to climate change mitigation, as well as food security.”
A significant proportion of these losses are caused by late harvest due to labor shortages, with crops languishing in the field before farmers can retrieve them. Small and medium-sized machinery may seem like the answer, but many one or two-axe machines are often unable to reach the inner sections of rice and wheat fields because of limited road access, or the fact that they are simply too heavy to carry.
“As mechanized land preparation works outwards, inner fields get ready for harvest first, but without any applicated technical solution,” he explains.
Could motorized scythes be the answer? Yahaya thinks so.
The other scythe
Motorized scythes are hand-operated tools used for mowing grass or reaping crops. Though largely replaced by horse-drawn and tractor-mounted implements, they are still commonly used in some areas of Asia and Europe.
Models specifically adapted for harvesting rice and wheat have been commercially available in Africa for over two decades and currently sell for $150-350, presenting the lowest initial investment cost of all engine-driven solutions on the market. The motor scythe also boasts the lowest harvest cost per hectare and is portable enough to reach inner fields.
Despite its relative affordability, uptake in much of West Africa has been slow, as many farmers have found the 10kg machinery too heavy for sustained use.
“Studies carried out in Benin, Burkina Faso, Cote d’Ivoire and Mali show that this rapid fatigue is caused by incorrect handling of the machinery, including flawed posture,” Yahaya explains. “This is simply because most operators have never undertaken official training for operating the tool.”
In a bid to address this challenge, Yahaya has been collaborating with Elliott Dossou, Sali Atanga Ndindeng and Ernst Zippel — all scientists at AfricaRice — to design and test potential solutions. Their proposal for the development of a Service Provider Harvest (SPH) model has been shortlisted for the GIZ Innovation Fund 2020 award, from a GIZ/BMZ-supported Innovation Fund.

Cut for service
The approach focuses heavily on capacity development, with an initial nucleus group of trainers taking the lead on activities such as recruiting and contracting service providers, providing training on harvesting and threshing, supporting aftersales services such as machine maintenance and repair, and helping to determine the optimum harvest time.
Under the proposed model, each trainer will be responsible for a group of around 50 service providers, who will receive guidance on understanding their role, finance, creating a network of client farmers, machine maintenance and use.
In addition to the financial rewards and aftersales services, the training opportunities will make this technology accessible to young entrepreneurs in rural areas. Earning up to $18 a day for harvesting and weeding services, those using the tool can expect to see a return on their initial investment in one to two months.
“Young people are the main prospective clients for this initiative,” says Yahaya. “With the motor scythe and related training, they can start earning serious money.” He stresses, however, that all farmers – regardless of age or gender – will be able to benefit from the job creation opportunities this initiative provides.
The initiative has been shortlisted for the GIZ Innovation Fund 2020. If selected, funding from the accelerator program would support testing, the integration of GPS sensors into the tools, creation of a platform for bank security and Carbon Credit earning, other technical activities.
Farmers in the Bale area, in Ethiopia’s Oromia region, mainly produce wheat and barley. Temam Mama was no different — but some six years ago, the introduction of the two-wheel tractor offered him additional opportunities. This was part of an initiative of the International Maize and Wheat Improvement Center (CIMMYT) and the Africa RISING project.
Selected as one of the two farmers in the region to test the technology, Temam took a five-day training course to understand the technology and the basics behind operating calibrating and maintaining the equipment.
The two-wheel tractor is multipurpose. By attaching various implements to a single engine, farmers can use it for ploughing, planting, water pumping, transportation, harvesting and threshing. For Temam, who had always relied on a rainfed agricultural system, the technology has high importance — he will be able to use the nearby river as a source of water for irrigation purposes.
To start off, Temam allocated 0.25 hectare from his four hectares of land for irrigation and planted potatoes for the first time. He was delighted with his harvest and the income he collected afterwards.
“From the first harvest, I was able to collect 112 quintals of potato and made roughly $1,529 in total,” said Temam.

Eternal returns
His productive journey had just started. This income allowed Temam to keep growing his business. He bought a horse and cart for $550 and taking the advice from the project team, he constructed a Diffused Light Storage (DLS) system to store his potatoes for longer.
To diversify his income, Temam occasionally provides transport services to other farmers. Over time, Temam’s financial capital has continued to grow, bringing new ideas and a desire to change. He went from a wooden fence to a corrugated iron sheet, to an additional three rooms by the side of his house for rentals.
He is fortunate for having access to the river and the road, he explains. He also sees new opportunities emerging as the demand for potato in the market continues to grow. The price for one quintal of potato sometimes reaches $76 and matching the demand is unthinkable without the two-wheel tractor, he says.
In addition to the two-wheel tractor, he has also bought a water pump to enable him to increase the area that he can grow irrigated potato, garlic and pepper on. His target is to have two hectares irrigated soon.

The future is bright
With his wife and four children, Temam is now living a well-deserved, healthy and exemplary life. Tomato, chilli and onion now grow on his farm ensuring a healthy diet, as well as diversified and nutritious food for the family. His economic status is also enabling him to support his community in times of need. “As part of my social responsibility, I have contributed around $152 for road and school constructions in our area,” noted Temam.
Under the Africa RISING project, Temam has proven that irrigation of high-value crops using two-wheel tractor pumping really works, and that it increases production and the profitability of farming. He has now stepped into a new journey with a bright future ahead of him.
“I plan to sell my indigenous cows to buy improved breeds and, in two to three years’ time, if I am called for refreshment training in Addis Ababa, I will arrive driving my own car,” concluded Temam.

Nearly 65,000 farmers in Nepal, 40% of which were women, have benefited from the Agronomy and Seed Systems Scaling project, according to a comprehensive new report. This project is part of the Cereals Systems Initiative for South Asia (CSISA), led by the International Maize and Wheat Improvement Center (CIMMYT) and supported by USAID.
One of the project’s most recent successes has been in accelerating the adoption of the nutritious and stress-tolerant mung bean in rice-wheat farming systems.

Rice-wheat is the dominant cropping system in the lowland region of Nepal. Farmers typically harvest wheat in March and transplant rice in July, leaving land fallow for up to 100 days. A growing body of evidence shows, however, that planting mung bean during this fallow period can assist in improving farmers’ farming systems and livelihoods.
“The mung bean has multiple benefits for farmers,” says Narayan Khanal, a researcher at CIMMYT. “The first benefit is nutrition: mung beans are very rich in iron, protein and are easily digestible. The second benefit is income: farmers can sell mung beans on the market for a higher price than most other legumes. The third benefit is improved soil health: mung beans fix the nitrogen from the atmosphere into the soil as well as improve soil organic content.”
Commonly used in dishes like dahl, soups and sprout, mung beans are a common ingredient in Asian cuisine. However, prior to the project, most farmers in Nepal had never seen the crop before and had no idea how to eat it. Encouraging them to grow the crop was not going to be an easy task.
Thanks to dedicated efforts by CIMMYT researchers, more than 8,000 farmers in Nepal are now cultivating mung bean on land that would otherwise be left fallow, producing over $1.75 million of mung bean per year.
The newfound enthusiasm for growing mung bean could not have been achieved without the help of local women’s farming groups, said Timothy J. Krupnik, CIMMYT senior scientist and CSISA project leader.

Bringing research and innovations to farmers’ fields
Introducing the mung bean crop to farmers’ fields was just one of the successes of Agronomy and Seed Systems Scaling, which was an added investment by USAID in the wider CSISA project, which began in 2014. The project aims to move agronomic and crop varietal research into real-world impact. It has helped farmers get better access to improved seeds and machinery and strengthened partnerships with the private sector, according to Khanal.
CSISA support in business mentoring and capacity building of seed companies to popularize newly released, biofortified and stress-tolerant wheat varieties has led to seed sales volumes tripling between 2014 to 2019. The project also led to a 68% increase in the number of new improved wheat varieties since the inception of the project.
Nepal’s National Wheat Research Program was able to fast track the release of the early maturing variety BL 4341, by combining data generated by the project through seed companies and the Nepal Agricultural Research Council (NARC) research station. Other varieties, including Borlaug 100 and NL 1327, are now in the pipeline.
Empowering women and facilitating women’s groups have been critical components of the project. Nepal has seen a mass exodus of young men farmers leaving the countryside for the city, leaving women to work the farms. CIMMYT worked with women farmer groups to expand and commercialize simple to use and affordable technologies, like precision seed and fertilizer spreaders.
Over 13,000 farmers have gained affordable access to and benefited from precision agriculture machinery such as two-wheel ‘hand tractors’ and ‘mini tillers.’ This is a major change for small and medium-scale farmers in South Asia who typically rely on low horsepower four-wheel tractors. The project also introduced an attachment for tractors for harvesting rice and wheat called the ‘reaper.’ This equipment helps to reduce the costs and drudgery of manual harvesting. In 2019, Nepal’s Terai region had almost 3,500 reapers, versus 22 in 2014.
To ensure the long-term success of the project, CSISA researchers have trained over 2,000 individuals from the private and public sector, and over 1,000 private organizations including machinery manufacturers and agricultural input dealers.
Researchers have trained project collaborators in both the public and private sector in seed systems, resilient varieties, better farming practices and appropriate agricultural mechanization business models. These partners have in turn passed this knowledge on to farmers, with considerable impact.
“The project’s outcomes demonstrates the importance of multi-year and integrated agricultural development efforts that are science-based, but which are designed in such a way to move research into impact and benefit farmers, by leveraging the skills and interests of Nepal’s public and private sector in unison,” said Krupnik.
“The outcomes from this project will continue to sustain, as the seed and market systems developed and nurtured by the project are anticipated to have long-lasting impact in Nepal,” he said.
The Cereal Systems Initiative for South Asia (CSISA) is led by the International Maize and Wheat Center (CIMMYT), implemented jointly with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI). CSISA is funded by the U.S. Agency for International Development (USAID) and the Bill & Melinda Gates Foundation.

Bram Govaerts, Director of CIMMYT’s Integrated Development Program, says Mexico already has projects like MasAgro whose potential can be activated and integrated as an investment.
MasAgro develops capacities in Mexican producers through the socialization of scientific knowledge and the use of rural knowledge to increase their yields and conserve natural resources.
On June 5, 2020, the world celebrates World Environment Day as COVID-19 continues to cause challenges and restrictions. Existing threats of climate change with the new challenges of a global pandemic adversely affect the agricultural sector, a mainstay of most sub-Saharan African economies. This situation calls for increased attention to how agriculture is practiced and natural resources — such as soil and water — are cared for.
Smallholder farmers in Zimbabwe are custodians of these natural resources, yet climate variability of shifting rainfall seasons, El Niño and droughts threaten successful rain-fed farming. Coupled with conventional farming practices such as tillage and deforestation, the soil structure and chemical quality are gradually degrading. Each passing year has resulted in declining yields, food insecurity and increased household vulnerabilities, particularly in drought-prone, low rainfall areas of southern Zimbabwe.
With support from the Swiss Agency for Development and Cooperation (SDC), the R4 Rural Resilience Initiative, led by the World Food Programme (WFP), aims to enable vulnerable, smallholder farmers to increase their food security, income and resilience by managing climate-related risks. Building on R4, WFP has just launched the Zambuko Livelihoods Initiative, focusing on social cohesion of communities, improved crop and livestock production and improved access to finance, with support from the United States Agency for International Development (USAID). The International Maize and Wheat Improvement Center (CIMMYT) is a partner to implement the project component on appropriate seeds and agricultural practices.
We discuss the R4 Rural Resilience Initiative with Christian Thierfelder, the Principal Cropping Systems Agronomist and a Strategic Leader for Africa at CIMMYT, and Munaye Makonnen, the Project Lead from WFP in Zimbabwe.

How is the R4 Rural Resilience Initiative responding to climate change challenges in the sites of intervention – Chebvute and Mwenezi?
Thierfelder: The R4 and Zambuko initiatives pursue an integrated approach to increase resilience of smallholder farming communities. Different partner organizations have come together in these projects to pursue different interventions such as building dams and vegetable gardens as community assets, financial education, promotion of improved climate-smart technologies such as drought-tolerant seed in combination with conservation agriculture, insurance, and linking farmers to markets. The combined actions address all needs and shortfalls in the target communities. We see a transformational change from mere subsistence farming to a more commercially oriented farming by targeted smallholders.
Makonnen: Recognizing the need to address livelihoods holistically, R4 offers farmers a set of integrated tools so that communities can better manage climate risks. Farmers participate in activities that enhance the natural resource base at watershed level, helping them adapt to climate change. They also benefit from a weather index insurance cover that protects them against drought and incentivizes them to engage in high-risk high-return investments. In the case of minor shocks, farmers have their savings groups to draw up on and can access small credit for income generating activities. With the aim of increasing productivity and income, conservation agriculture practices are promoted. For their surplus production, participants are also supported in accessing markets. The project also plans to include a component on climate services that will allow communities to mitigate the impacts of disaster risk, increase production and enhance adaptation to climate change.
Since inception, how have the farming communities responded to the technologies and practices introduced in their respective sites?
Thierfelder: Farming communities were very skeptical initially about this new approach. However, the varieties and cropping systems displayed in our 10 mother trials showed dramatically higher yields than farmers observed in their own fields, so it was not difficult to get 200 baby trial farmers to experiment with the technology. During the 2019/2020 cropping season, farmers got even more excited to see maize and legume yields thrive in their baby trials while crops planted under conventional agriculture failed. In the next cropping season, we hope to reach the tipping point of farmers trying and experimenting with these climate-smart agriculture technologies to achieve a transformational change towards more resilience.
Makonnen: Looking at the performance of the trials, farmers can see for themselves that the agricultural practices promoted by the project result in higher yields. They also get practical experience by trying these out on their own fields. Such an approach has worked well in terms of getting farmers to become interested in and eventually adopt conservation agriculture principles because it is not just based on theory — farmers can actually see and experience the change for themselves.
Even in times of COVID-19, the work must continue, observing social distancing and using facemasks. Christian Thierfelder outlines trials with farmers in Mwenezi, Zimbabwe.
In the wake of the COVID-19 pandemic and disturbance to agri-food systems, how is the R4 Rural Resilience Initiative addressing the emerging challenges?
Thierfelder: We have created the base of more resilient farming systems that should positively respond to all external shocks – droughts, floods and maybe a virus as well. In our technology package we do promote self-pollinating legumes such as cowpea and groundnuts which can be grown even when farmers are cut off from supply chains for seed and fertilizer. We therefore hope that this can be a contribution to reducing the negative impact of the COVID-19 crisis.
Makonnen: As COVID-19 is compromising food security, it is now more important than ever to ensure that agricultural production continues to function smoothly. R4 continues to provide all the services in its integrated risk management package despite the pandemic. As farmers face challenges in production, including limited access to labor, we hope that high yielding and less labor-intensive conservation agriculture practices promoted by R4 really come into their own. Ensuring the safety of our beneficiaries, staff and partners is a priority for WFP so we have developed guidelines for R4 implementation in the context of COVID-19. For instance, trainings are taking place in smaller groups, social distancing is observed in all activities, messages on COVID-19 prevention are shared with beneficiaries and we are also looking into digital solutions to continue implementation during these unprecedented times.
Looking ahead, how will the adoption of appropriate agricultural practices and seed varieties strengthen the resilience of the farming communities?
Thierfelder: Our approach has been multi-faceted addressing different areas of concern to the farmers: income generation, credit, improved productivity, insurance and marketing. We believe that with this mix of interventions farming can more effectively withstand external stresses. However, we also realize that adoption does not happen overnight and requires a significant experimentation and learning process with farmers. WFP has seen the need for longer term investments, and this is now beginning to pay off.
Makonnen: Adoption of appropriate agricultural practices and seeds is just one of the components of R4. We know resilience requires a holistic approach which is why we have a set of interventions within R4 involving multiple partners. R4 will continue to work across the entire value chain bringing together natural resource management, access to financial services, access to inputs and markets and promotion of appropriate agricultural practices so that the farmers we work with are well equipped to manage risks and become resilient to the changing climate and risks to their food security.

The COVID-19 pandemic continues to transform the way the world operates, and agricultural production systems are not exempt.
Even in countries that have identified the agricultural sector as an essential one, ongoing restrictions on transport and freedom of movement are causing disruptions across the value chain — with potentially devastating impact on already fragile food systems in Latin America, sub-Saharan Africa and South Asia.
With this in mind, systems agronomists and mechanization specialists at the International Maize and Wheat Improvement Center (CIMMYT), discuss the impact of restrictions on agricultural labor and production, and the role farm mechanization can play in addressing new challenges.
What are the implications of the agricultural labor shortages that are emerging in Africa and Latin America as a result of COVID-19 restrictions?

Frédéric Baudron: The pandemic has demonstrated that food production systems around the world — even in countries where agriculture is thought to be highly mechanized — are highly dependent on farm labor.
Africa is often presented as being dominated by farms which rely mainly on the labor of family members. Therefore, one could expect that Africa would be spared from the consequences of unavailability and/or unaffordability of hired labor. However, a recent CIMMYT study shows that farming systems in Africa are far more dependent on hired labor than commonly thought, and that the quasi total dependence of smallholder farming on family labor is a myth. Depending on the farming system, a complete loss of hired labor could lead to a productivity decrease of up to 20% in Eastern and Southern Africa. Hired labor is also likely to be replaced by child labor.
Because most production on the continent is rainfed during a single season, most farmers only plant and harvest once per year, making the timing of each task critical. A delay in planting because of labor shortages — as will soon occur Ethiopia — could lead to dramatically reduced yields. A delay in harvesting — as is currently experienced in Zimbabwe — means a large fraction of the crop is likely to be spoilt in the field.
Jelle Van Loon: The situation is similar for Mexico and the general Central American corridor, although the main production cycle is only just starting. Proper land preparation and timely sowing are critical, not only in terms of food production and achieving proper yields, but also to ensure that farmers have a stable income at the end of the year. This is especially important now, as financial and food reserves are shrinking at a faster pace due to COVID-19 restrictions that heavily affect demand on informal markets.

Are you seeing a similar situation in South Asia?
Timothy Krupnik: Depending on the country, we’ve seen either abrupt interruptions in the movement of agricultural laborers — for example in India where millions of migrant laborers have not been able to travel home during lockdown — or an influx of people from urban areas who fled to their villages when lockdown began.
In the latter case, one might expect this to increase labor availability for farming, but we tended to observe the reverse. People remain largely frightened of coming out of their homes, so even in rural areas which saw an influx of people, labor availability has not necessarily increased. Where laborers are willing to work, our initial scan of the evidence indicates that daily wage labor costs have also increased considerably due to risks of infection spreading. In either situation, smallholder farmers who need to hire labor to assure crucial crop management activities like planting or harvesting are suffering. There are reports emerging also of increased child labor in the region as schools are closed and resource-poor farmers are allocating family members and children to work where they can’t afford to hire labor.
M.L. Jat: I would like to cite the specific example of intensive rice-wheat rotation in India’s breadbasket and the Green Revolution corridors in the western Indo-Gangetic plains, which provide the bulk of cereals to the national food basket. An ex-ante analysis on the consequences of the reverse migration of the agricultural workforce and social distancing due to COVID-19 revealed that a delay in the transplanting of rice seedlings by two weeks is likely, which will delay rice harvesting and consequently delay the planting of wheat. This will potentially lead to rice and wheat production losses of 10-25%, worth up to $1.5 billion.
In addition, the shorter turn around between harvesting rice and planting wheat may further increase the incidence of rice residue burning. This is a major problem which creates significant health issues and may exacerbate the threat of COVID-19 by increasing both infection rates and disease severity.
Krupnik: The situation has increased interest and policy to support use of scale-appropriate machinery for operations like harvesting. In Bangladesh, for example, there was a recent and very serious risk of losing much of the rice harvest as the monsoon has started early and flash flooding has been a concern. Without manual laborers to harvest the crop, CIMMYT-led projects like the Cereal Systems Initiative for South Asia – Mechanization and Extension Activity (CSISA-MEA) have played a key role in assisting the movement of combine harvesters and crop reapers to areas at risk of crop losses and helping to assure the rice crop is harvested on time.

It sounds like these machines were instrumental in avoiding crop losses. Does this mean that mechanization has a key role to play in lessening the impact of these labor shortages?
Krupnik: During the COVID-19 crisis, scale-appropriate machinery has become even more important for mitigating labor shortages. We work to facilitate the availability of scale-appropriate machinery not only so that farmers can buy and use equipment, but also by encouraging those who own machineries to become entrepreneurial service providers who offer efficient and mechanized land preparation, planting, irrigation, harvesting and post-harvesting to other farmers on an affordable fee-for-service basis.
This is a win-win situation for farmers who can’t access or afford the escalating costs of labor. In the COVID-19 crisis, these arrangements assist in responding to the labor crunch in locations where resource-poor farmers are most in need, and also allow farmers to get crucial work done while maintaining and encouraging social distancing.
Baudron: Over the past seven years, CIMMYT and its partners have fine-tuned technologies and developed delivery models — based on rural service providers supported by private sector companies — to scale the use of small machines in East and Southern Africa. These are profitable for both farmers and service providers and reduce labor requirements tremendously.
In Zimbabwe, we found that labor requirements were 15 times lower when establishing a maize field with a direct seeder pulled by a two-wheel tractor, and 23 times lower using a similar technology for establishing wheat in Rwanda, compared to the conventional method based on labor and draft power. A ton of maize that would take 12 people a full day to shell manually, can be shelled in one hour using a small double-cob sheller that costs about $300.
Jat: Rapid policy decisions by sub-national and national governments on facilitating more mechanized operations in labor intensive rice-wheat production regions will address labor availability issues while contributing to productivity enhancement of succeeding wheat crop in rotation, as well as overall system sustainability. Our ex-ante analysis on the implications of labor shortages in rice-wheat rotation in the western Indo-Gangetic plains due to COVID-19 indicates that adoption of scale-appropriate farm mechanization has the potential to stabilize the food production as well as reducing the income losses and air pollution surges in northwest India.

The situation in the regions each of you have mentioned is unique, but are there any global trends that you’ve noticed? And if so, can other regions learn from these localized experiences?
Krupnik: A huge part of what we do as a research and training institute is facilitate exchanges of information across continents and countries. Different types and designs of machinery that can be used in similar circumstances can be shared, as can business models supporting service providers.
Importantly, part of the concept of ‘scale-appropriate mechanization’ is also learning when and where machinery makes sense — where labor is not scarce and rural communities are highly dependent on income from labor to sustain their communities, some forms of mechanization may not be appropriate. We work to understand these dynamics and target the right machines in the right time and right places.
Van Loon: In addition to reducing pressure on available labor and alleviating drudgery, modern farm equipment tailored to the needs of smallholders can also increase competitiveness, as it allows for higher precision and efficiency.
In this sense, scale-appropriate mechanization can stimulate rural transformation incentivizing short and efficient value chains while ensuring stable food provision — aspects that have become essential to navigating the present crisis.
Has the current pandemic brought up any new perspectives in terms of how you consider labor and mechanization?
Baudron: We often look at yield and area planted in staple crops to assess the food security situation of a country during a particular year. This pandemic has shown us that we need to pay more attention to labor productivity. In many countries, policy-makers and development agents fear that mechanization will displace labor, but the dependency of staple crops on labor is a threat to food security, as we currently see in Africa and South Asia.
If the production of fruit, vegetables, cash crops, and so on will continue to depend on manual labor, it is essential in my view for critical tasks in the production of staples to be mechanized — particularly planting and harvesting. This will ensure the resilience of national food systems in the case of a future disruption similar to the COVID-19 pandemic.

Not only is it the origin of maize – one of CIMMYT’s focus crops – it also inspired the birth of its headquarters, which has served as the institute’s mothership since its establishment in 1966.
CIMMYT’s crop-breeding research begins with its genebank, a remarkable living catalog of genetic diversity comprising over 28,000 unique seed collections of maize and over 150,000 of wheat. The genebank was established at CIMMYT’s headquarters in 1986 and to date is the world’s largest and most diverse collection of maize and wheat. Like clockwork, every year, more than 1,500 maize and wheat seed shipments leave Mexico to reach as many as 800 recipients in over 100 countries.
In one way or another, the world’s maize and wheat have a link back to Mexico: be it through pest-resistance trials in the Agua Fria or Tlaltizapan hub or heat-resilient wheat trials in the scorching fields of Obregon. The country’s diverse ecosystems which allowed for Norman Borlaug’s shuttle breeding in the 1940s remain instrumental for today’s researchers’ work to develop innovative crops and sustainable farming systems worldwide.

CIMMYT has been working hand in hand with Mexico’s Secretariat of Agriculture and Rural Development (SADER) on MasAgro, a project that promotes the sustainable production of maize and wheat in Mexico.
In the conversation below, Martin Kropff, Director General of CIMMYT, and Bram Govaerts, CIMMYT Representative for the Americas and Director of the Integrated Development Program, explore topics such as Mexico’s food security and agriculture while COVID-19 disrupts the nation’s status quo.
Has the COVID-19 pandemic exposed any vulnerabilities in Mexican food security?
Kropff: Albeit Mexico produces a lot of food – in fact, I believe that it currently ranks 11th in food production globally – it still imports food from other countries, particularly staples such as maize, wheat and rice from the U.S. The current pandemic poses a threat to open trade, and Mexico could also be affected by trade restrictions that other countries impose to protect their people and internal markets from food shortages.
Govaerts: At the same time, the pandemic is reducing economic activities everywhere to minimum levels. This poses a threat to food production given that farmers and agricultural workers in Mexico, and most of the northern hemisphere, are just about to begin the growing spring/summer season. Mexico’s fields need to be prepared for sowing and farmers need certainty as they take risks by investing today for a harvest that will come within several months.
How is CIMMYT helping to reduce these vulnerabilities?
Govaerts: CIMMYT is working with Mexico’s Agriculture Department (SADER) and the private and social sector to address these threats.
Kropff: In fact, we see that Mexico is already answering to a CIMMYT-endorsed Call to Action For World Leaders, which was published on the Food and Land Use Coalition website. This call to action urges countries to implement three key measures to avert a global food crisis that could increase the number of people suffering from chronic hunger by millions: keep the supply of food flowing across the world; scale support to the most vulnerable; and invest in sustainable, resilient food systems.

What is the role of CIMMYT’s collaboration with Mexican government bodies in this process?
Govaerts: In the fields there is potential to respond and avoid that today’s health crisis becomes tomorrow’s food crisis. CIMMYT is working with SADER and Mexico’s National Research System (INIFAP) to contribute to a stable supply of basic grains grown sustainably in Mexico by offering technical advice to the more than 300,000 farmers that participate in MasAgro, CIMMYT’s bilateral collaboration project with Mexico for sustainable maize and wheat production.
Currently, MasAgro technicians and extension agents are working with smallholder farmers in the center and south of the country to prepare soils for sowing, advising on optimal sowing densities and use of high-yielding improved varieties, agro-ecological pest management, fertilization, irrigation, among other activities that are essential to begin the crop production cycle in time.
Mexico and CIMMYT are also working with the agri-food sector to build farmers’ capacities to increase grain production sustainably and to sell the surplus to local and multi-national agri-food companies in Mexico. This is part of wider country plans which are called Maize for Mexico and Wheat for Mexico.
Kropff: These plans are very much in line with the call for governments to work with the philanthropic and private sectors to strengthen and scale out targeted food programs by linking them to foods that promote health and sustainable production. Currently we work with Nestlé, The Kellogg Company, Grupo Bimbo, and Walmart Foundation, among others, to create a pull from the market for sustainable agriculture for smallholder farmers. We call this sustainable sourcing.
How can we strengthen Mexico as a country of agricultural crops research and design activities?
Kropff: CIMMYT has been instrumental to public policy formulation in Mexico and has been positioned as one of Mexico’s most trusted partners over the past 10 years.
Govaerts: Exactly, and the numbers speak for themselves. As a result of the collaboration with more than 150 collaborators from the public, private and social sector, MasAgro has had a positive impact in the lives of more than 300 thousand farmers who have adopted conservation agriculture, improved seeds and sustainable farming technologies on more than 1 million hectares across Mexico.
Kropff: It would be great if Mexico continued investing in integrated development projects like MasAgro, and scaled out sustainable farming practices and technologies with innovative approaches like responsible local sourcing, which I mentioned just before while it promotes the replication of the MasAgro model in other countries.

How can we strengthen farmer’s access to better crops and better farming techniques?
Kropff: It is imperative to CIMMYT to improve farmers’ economic opportunity. This cannot be done without essential ingredients such as access to markets, capacity development, technology, and inputs like seeds and fertilizer. And most importantly, better crops and farming technologies are worthless without the national agricultural research systems’ buy in and trust.
Govaerts: This is very much at the heart of what we do together with maize farmers in Mexico in MasAgro. CIMMYT breeds maize hybrids with conventional technologies and improves native maize seed in collaborative projects with farmers. Then this improved maize seed is tested in collaboration with the local seed sector that, in turn, commercializes the best adapted materials in Mexico’s growing regions. These seed companies are small and medium enterprises that generate economic development in the center and south of the country.
Kropff: Similarly, in a project that started in 2019 in eastern and southern Africa, we reach farmers in Malawi, and soon in Rwanda and Tanzania, with our improved seeds through small seed companies which play the key role of ‘connector’ in intricate and complicated markets which often are ignored by large seed companies. Then, CIMMYT researchers undertake varietal trials and track genetic gains in farmers’ fields and share the findings with the broader agricultural community.
What changes can we expect in the nation’s food supply chain management after COVID-19?
Kropff: All crises bring challenges and opportunities. I believe that Mexico could take this opportunity to make its supply and value chains more integrated, resilient and flexible.
Govaerts: Mexico can become the leader of innovation that integrates traditional and scientific knowledge.
What role does CIMMYT want to play in the future?
Kropff: I see CIMMYT working even closer to the farming communities but especially along the whole value chain with science and data towards improved decision-making.
Govaerts: CIMMYT can be a catalyst of integrated programs. We want to keep discovering and helping to implement new solutions for the world’s poor and food insecure and work toward achieving the Sustainable Development Goals.

“Agricultural research for development is increasingly being held accountable to demonstrate that research goes beyond successful pilots,” said Iain Wright, deputy director general of research and development at the International Livestock Research Institute (ILRI).
In a bid to scale impact of its research outputs, ILRI has recently undertaken a systematic review of the scaling tools and processes available to help guide and improve the organization’s efforts.
The Scaling Scan has been incorporated into a new scaling framework for ILRI projects and for the CGIAR Research Program on Livestock (Livestock CRP). The Scaling scan, developed in 2017 by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with PPPLab at SNV, is one of three tools that have been identified as most suitable for the ILRI and CGIAR operational contexts.
“ILRI’s scaling framework applies the Scaling Scan and the USAID Scaling Pathway methodology before diving deep using the RTB/Wageningen Scaling Readiness methodology,” explained CIMMYT Scaling Coordinator Maria Boa. “It’s exciting because it aligns some of the best available tools to scale impact with a systems view.”
Designed for use by anyone involved in pro-poor and sustainable development programs looking to scale impact, the CIMMYT Scaling scan is found to be user-friendly and quick to help project implementation teams understand and define their scaling ambitions and asses their scaling environment. Though it is often applied as part of annual project review meetings, the tool can in fact be used at any stage of a project’s lifecycle. This helps stakeholders understand the multiple dimensions of scaling and the significant role nontechnical factors play in a scaling mindset.
CIMMYT shared lessons on how the methodology can be applied in a workshop setting and the Livestock CRP team has already used these to organize two workshops around improving productivity and incomes in Uganda’s pig value chain. The workshops, held in November 2019 and February 2020, brought together value chain actors, CRP researchers and project staff to better understand the multiple dimensions of scaling, develop realistic scaling goals, and identify key bottlenecks and opportunities using the Scaling Scan.

While technology and data analysis have revolutionized farming in high-income countries, farmers in low-income nations have often been left out. New tools developed by CGIAR centers are narrowing the digital divide for smallholder farmers. These tools are increasingly gaining international notice beyond the field of agriculture, as a recent international award attests.
The 2020 Innovative Applications in Analytics Award (IAAA) was awarded to the International Maize and Wheat Improvement Center (CIMMYT), the Alliance of Bioversity International and CIAT, and the International Institute for Applied Systems Analysis (IIASA). Their tools, which help farmers to increase productivity, use more sustainable practices and access markets, topped bids from international technology companies and universities with projects applied to various fields.
“The award from this collaboration highlights the strengths of bringing together our research centers under One CGIAR,” said Daniel Jiménez, an Alliance scientist who was part of the winning team. “It shows that we can collaborate and compete at the highest level when it comes to applying science to global challenges.”
CIMMYT, CIAT and the IIASA won with their ‘Integrated Analytics for Sustainable Agriculture in Latin America’ projects. Finalists included projects focused on a wide range of analytics tools used in pricing, optimizing gas transmission, taxi guidance and management of hospital discharges.

“The IAAA award emphasizes novelty and creativity in analytics applications along with real-world impact,” said Pallav Chhaochhria, Director of Equities Trading at Citigroup and co-chair of the IAAA selection committee, during the virtual award ceremony.
The winning submission recognizes groundbreaking data systems and tools by publicly funded researches and field technicians who advise more than 150,000 farmers who participate in MasAgro, CIMMYT’s bilateral collaboration project with Mexico for sustainable maize and wheat production.
The multi-disciplinary team developed a system to track over 500 variables during the growing cycle at each plot monitored. These variables are subsequently analyzed in combination with geographic, weather and market data obtained from open sources of information. Data analysts and researchers mine these databases to find correlations or patterns that help identify limiting factors and the best management practices for each plot.
The resulting analytics feed an application called AgroTutor — available on Android and iOS — which offers free information to farmers, including historic yield potential, local benchmarks, windows of opportunity, recommended agricultural practices and commodity price forecasting.
“Although sophisticated data analyses have been used in agriculture before, small and medium-sized farmers have seldom benefited from a combination of systems and tools that offer predictive and prescriptive site-specific analytics,” said Andrea Gardeazabal, Information and Communication Technology for Agriculture, Monitoring & Evaluation Manager for CIMMYT’s Integrated Development program. “MasAgro and AgroTutor have proven that resource-constrained farmers can benefit from high-end innovative analyses.”
A major farmer survey is gathering data to understand how smallholders in Laos are responding to fall armyworm invasion and develop agroecological management options to control its spread.
The study, led by the International Maize and Wheat Improvement Center (CIMMYT) in partnership with the Lao Farmer Network (LFN) and the National Agriculture and Forestry Research Institute (NAFRI), is CIMMYT’s first official research initiative in the country.
Farmer surveys are being conducted in some of the country’s key maize farming areas, recording attempts to manage the pest and laying the groundwork to raise awareness on sustainable best-bet agroecological strategies that promote a healthy system approach to maize farming, says Horst Weyerhaeuser, a scientific program consultant working with CIMMYT.
“Currently, researchers, policy makers and extension officers possess little information on fall armyworm pest management and control in Laos,” he explains. “The survey is working to build a knowledge-base.”
In June 2019, CIMMYT and national research scientists confirmed that fall armyworm, a global pest that affects the food security of millions of maize farmers, was present in the country.
Working with CIMMYT, LFN trained lead farmers to conduct surveys and collect data from farmers in their local areas. The network has also been distributing a series of infographics and videos in local languages, developed by CIMMYT and translated with major support from HELVETAS Swiss Intercooperation and the Lao Farmer Rural Advisory Project, to describe appropriate pesticide use and sustainable farming practices to limit impact on harvests.
“The survey data explores how farmers respond to the armyworm in their maize fields, so that integrated pest management strategies can be promoted for successful pest control and especially to limit excessive use of harmful pesticides,” says Phoutthasinh Phimmachanh, who leads the LFN secretariat. “The survey also asks about farmers’ plans for the upcoming rainy season and if they experienced a fall armyworm infestation in 2019 will it change their crop selection and planting schemes.”
The initiative is part of a larger strategy to work with government and farmers in southeast Asia to build a knowledge base on sustainable maize farming through the CGIAR program on MAIZE. Due to the impact of COVID-19, researchers are currently exploring options to continue these and additional surveys digitally and via telephone.
As maize farming increases, so does the risk fall armyworm poses to farmer livelihoods

Maize is becoming an increasingly important cash crop in southeast Asia as diets change and consumer preferences for white meat and pork drive a transition from subsistence to commercial maize feed production. Farmer focus groups in northern Laos suggest that maize sales deliver more than 60% of smallholders’ annual cash income.
“Maize is the only cash crop for thousands of smallholder farmers in Laos. Fall armyworm poses a credible threat to their livelihoods and could push them to a vicious circle of poverty and damage to the environment,” explains CIMMYT economist Amjath Babu.
“We want to confirm anecdotal accounts suggesting uninformed farmers are buying whatever pesticides they can get their hands on in a bid to control the pest’s impact on harvests. This reaction mimics that of initial farmer responses in sub-Saharan Africa when the pest first broke out there in 2016.” In this sense, he adds, CIMMYT’s partnership with LFN helps to measure the implications of fall armyworm and the potential for this pest to reduce farmers’ profit margins while encouraging unsustainable pesticide use.
Pesticides must be used with extreme caution and only appropriately if they are to be a part of any fall armyworm management regime, warns CIMMYT Senior Scientist Tim Krupnik.
“The pest has particular habits — like living under leaves, hiding in hard to reach places of the plant, and feeding mainly at night,” he explains. “This makes indiscriminate application of insecticides relatively less useful.” It could also inadvertently contribute to the loss of biodiversity and ecosystem services through overuse of pesticides that cause mortality for natural enemies and parasitoids.
Scientists want to explore whether the higher production costs farmers may incur through additional insecticide purchase is encouraging a shift from maize cash crop monocultures to a more diverse production including replacement or rotations with cassava, fodder crops, and rotational grazing, where feasible.
“By building an evidence base we can work with the National Agriculture and Forestry Research Institute,the agricultural department and farmers to build sustainable, resilient maize farming systems that ensure farmers continue to cash in on maize while diversifying production into sensible alternative crops, with emphasis on protecting their health and the environment,” Babu adds.
Fall armyworm survey part of a larger increase in maize research in southeast Asia
The expansion of maize in Laos has been accompanied by a progressive decrease in landscape and agricultural biodiversity, as farmers respond to opportunities to export maize at relatively profitable prices, largely to neighboring Vietnam and China, by resorting to an expansion of slash-and-burn agriculture with shortened fallows. The rapidly growing demand for maize has resulted in unsustainable farming systems intensification, explains Krupnik, with many farmers clearing forests to plant, and using excessive amounts of herbicides to keep weeds at bay.
“Combined with the fall armyworm invasion, potentially dangerous pesticides have been added to this scenario, with quite concerning potential consequences for further biodiversity loss and contamination of mountain streams by agrochemicals,” he says.
“Projects run by Helvetas, which has helped support our research through coordination and convening efforts, have measured dangerous levels of pesticides in the blood of samples taken from farmers and their families and government officials.”
Maize is important for income generation, but more sustainable and diverse cropping systems are needed to reduce the impact on biodiversity, while avoiding the worst pesticides that comprise human health. The data generated from this research will help design strategies to respond to these problems with more appropriate agricultural practices.
The ministry of agriculture has welcomed support from CIMMYT’s maize systems experts to aid in building a base of knowledge to inform the development of agricultural policy, says Chay Bounphanousay, director general of the National Agriculture and Forestry Research Institute. “With the rise of maize farming and the associated challenges and opportunities it brings, an increase in research will inform agricultural policy to improve farmer livelihoods while protecting the environment.”

Highland maize production systems in Southeast Asia are crucial in that they generate considerable income for otherwise impoverished farmers in remote upland areas. However, they are largely unsustainable, involving destructive slash and burn agriculture, with increasingly short fallow times between crops. Additionally, and in response to historically favorable maize markets, many farmers now plan to expand maize cultivation areas, which is anticipated to have serious consequences for biodiversity loss and ecosystem services.
The arrival of fall armyworm adds additional pressures that could lead to intensification of management practices and over-use of insecticides; a partial transition away from maize as farmers respond to the pest by growing other crops and initiating new land use practices; and increased use of sustainable intensification practices that employ agroecological options for fall armyworm management.
Responding to fall armyworm (Spodoptera frugiperda J.E. Smith) with data, evidence and agroecological management options in Lao PDR is a research project funded through the CGIAR Research Program on Maize (MAIZE). It sees CIMMYT partner with the Laos Farmer Network (LFN) and the National Agriculture and Forestry Research Institute (NAFRI) to understand how smallholders in the country are responding to fall armyworm invasion and develop agroecological management options to control its spread.
Working with CIMMYT, LFN will train lead farmers to conduct surveys and collect data from farmers in their local areas. The network will also distribute a series of infographics and videos in local languages, developed by CIMMYT and translated with major support from HELVETAS Swiss Intercooperation and the Lao Farmer Rural Advisory Project, to outline appropriate pesticide use and sustainable farming practices to limit impact on harvests. An estimated 2,000 farmers will receive information on research results and fall armyworm management advice.
The results will offer evidence-based insights allowing LFN and the Lao Upland Rural Advisory Service (LURAS) project to plan future extension and development activities more effectively, while also identifying crucial additional research needs given these urgent issues and circumstances.
This research will yield actionable lessons and position LFN and the LURAS project to provide farmers with context-specific and agroecological fall armyworm management advice that responds to insights derived from farmer surveys that characterize pest incidence and severity, and relates them to farmers’ management practices, farm- and landscape-biodiversity, and location.
