Boddupalli Prasanna, director of the global maize program at the International Maize and Wheat Improvement Center (CIMMYT), a global research body, called on scientists to help countries in finding faster solutions to the effects of COVID-19 on food security.
“I am particularly worried about farmers, especially smallholder farmers, who are quite vulnerable to the ongoing challenge,” Prasanna said in a statement.
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.

A first outbreak of maize lethal necrosis was found in Kenya in 2011 and researchers immediately became active because they knew that timely action was needed to prevent irreparable damage. This viral disease was decimating maize fields and spreading rapidly in east Africa through contaminated insects and seeds.
When a maize lethal necrosis (MLN) outbreak happened in Kenya in 2011, scientists knew they needed to act fast. This viral disease, new to Kenya, was decimating maize fields. Within a few years, the viral disease spread rapidly in eastern Africa, through both insect vectors and contaminated seeds. If the virus were to spread into southern or West Africa, it would spell disaster for the smallholder farmers across the continent who depended on maize as a staple crop and for their family’s income and livelihoods.
The International Maize and Wheat Improvement Center (CIMMYT) and its partners immediately took action to impose a strict seed quarantine and restrict the movement of seed between eastern Africa and other regions in Africa. In addition, they worked intensively on developing and disseminating improved maize cultivars with tolerance or resistance to MLN, undertook extensive surveillance efforts, and sensitized partners on the importance of producing and commercializing MLN-free seed.
Due to these efforts, in the last nine years MLN has not been reported in sub-Saharan Africa outside of eastern Africa.
On the occasion of a recent publication on Virus Research about how MLN was contained, we interviewed B.M. Prasanna, director of the Global Maize Program at CIMMYT and the CGIAR Research Program on Maize (MAIZE), to discuss the MLN success story, the global COVID-19 crisis, and the similarities in the challenge to tackle plant and human viral diseases.

What were some of the extreme measures CIMMYT had to take to stop the spread of MLN?
The first step that we had to take in the fight against MLN was to rigorously analyze seed for any possible contamination with MLN-causing viruses and restrict movement of seed from eastern Africa to southern Africa.
The second most important step was to sensitize the national partners and the commercial seed sector about the danger of seed contamination with MLN-causing viruses, and how seed contamination can lead to the proliferation or spread of the disease.
The third important step was to build a new MLN quarantine facility in Zimbabwe, in partnership with the National Plant Quarantine Institute. Only when that quarantine facility was functional in 2017, we reinitiated transfer of research material from CIMMYT’s breeding hub in Kenya to CIMMYT in Zimbabwe. Only when the materials were certified to be MLN-free both in Kenya and Zimbabwe, through plant-by-plant analysis using immunodiagnostic kits, the seed was multiplied and further distributed to partners. So, the principle of containment and effective management is extremely important, whether it is a plant viral disease or a human viral disease.
We must note here that in terms of scale and intensity, as well as global effects and implications, any plant disease, including MLN, cannot be compared with a pandemic like COVID-19, which has affected every aspect of our lives.

How do you think the COVID-19 pandemic is going to impact our food systems?
We are indeed in a grim situation. The pandemic will undoubtedly have a serious effect on food security.
Many countries which do not have enough food reserves or those where the food systems are vulnerable to shocks like this are suffering. The people’s capacity to procure inputs for agriculture, including seed, is going to be affected too, as the markets are affected. This is really a serious situation that we all should be concerned about. The CGIAR has an important role to play, in terms of working closely with national partners and mitigating the impact of COVID-19 on agriculture.
We should be particularly worried about farmers, especially smallholder farmers, who are quite vulnerable to the ongoing challenge. Even without COVID-19, agriculture in many developing countries worldwide has been already under distress. Small and marginal farmers were often unable to find a market for their produce and earn sufficient income to support their families. Their livelihoods are fragile, and vulnerable to climate change and volatile market prices. The ongoing COVID-19 crisis is unfortunately compounding the crisis.

What lessons can agricultural research learn from this pandemic?
What do these pandemics or epidemics teach us? They remind us that systems need to be in place to prevent the proliferation of such diseases, whether it is plant diseases or animal diseases or human diseases. No country can be considered completely safe, and such diseases do not discriminate between a developed and a developing country, or the rich and the poor.
The second most important lesson is emergency preparedness. Whenever such devastating transboundary viral diseases show up, how quickly the country can respond — containing that infected area and not allowing the disease to spread, and then mitigating the damage systematically and quickly — is key. This is not the first time that a disease like MLN has emerged. There could be more serious viral or fungal diseases that could emerge in the future due to various reasons, including changing climates, international trade, movement of human beings, air currents, etc. There are multiple ways that diseases can go across continents, across countries within a continent, and within countries. Therefore, the key is how well we can capacitate the national systems to be able to proactively prevent, detect, and intervene very fast.
Another big lesson here for agricultural systems is that a problem that happens in some other continent cannot be ignored because you work in a different continent. What COVID-19 shows is that the world is far more connected than we think.

For you, what is the biggest takeaway from the MLN success story?
I won’t say it is still a complete success. Through intensive partnerships and efforts, we were able to prevent the disease from devastating maize production in millions of smallholder farmers’ fields in sub-Saharan Africa. Since 2014, there has been no new country in Africa — outside eastern Africa — that has reported an outbreak of MLN. That, to me, is a tremendous success.
The work is still not over. The journey has to continue. And we still need to make sure that countries are continuously protected from devastating diseases like MLN. MLN is still not eradicated from eastern Africa. It may not be even possible to completely eradicate this disease, as the two viruses that together cause it can survive not just on maize but on multiple grasses. We can however contain the disease and limit its impact through continued efforts, like what we have done for the past 7 or 8 years. But if we lower our guard, there is a very high likelihood that the disease can still spread to other countries in sub-Saharan Africa, especially the major maize-growing countries in southern Africa or West Africa. Efforts need to continue. So, let us continue to maintain a high vigil to protect the smallholders in Africa from transboundary diseases like MLN.
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.
“COVID-19 will make African governments identify agriculture as an essential sector that deserves maximum support and protection,” explains Stephen Mugo, Africa regional representative at the International Maize and Wheat Improvement Center, Kenya. “Urgent action is needed to ensure that adequate credit and other support are available when and where needed to strengthen farmers’ ability to deliver.”

World’s leading food security think-tank and research centres have recommended Bangladesh to ensure transportation of food from rural to urban areas and the flow of crucial inputs to farmers through market systems so that risk to food system during Covid-19 pandemic can be averted.
Of the 6,000 plant species that have been cultivated by humans, just nine of them account for 66% of cultivated crops, according to the FAO’s 2019 report from the Commission on Genetic Resources for Food and Agriculture. Of the 7,774 local breeds of livestock worldwide, 26% are in danger of becoming extinct.
That poses dangers for the robustness of the environment, the safety of our food supply chain, and even our potential exposure to pandemics, due to diseases that jump from animals to humans. It also makes our food less nutritious, less interesting—and less unique.
The COVID-19 crisis could offer a chance to reassess the way we eat—to revamp the diversity of our diets and our food systems, revisiting local and forgotten foods, particularly when it comes to fruits and vegetables.

Alarmed by the risk of global and regional food shortages triggered by the COVID-19 pandemic, a coalition of businesses, farmers’ groups, industry, non-governmental organizations, and academia has called on world leaders urgently to maintain open trade of their surplus food products.
Published by the Food and Land Use Coalition (FOLU) on April 9, 2020, and signed by 60 experts, the call to action urges world leaders to keep food supplies flowing, specially support vulnerable people, and finance sustainable, resilient food systems.
Covered by major world media, the declaration encourages governments to treat food production, processing, and distribution as an essential sector — similar to public health care — and thus to support continued, safe, and healthy activities by farmers and others who contribute to the sector, according to Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT) and a signatory of the call to action.
“Consumers in low-income countries face the greatest threat of food insecurity,” said Kropff. “Their tenuous access to nutritious food is jeopardized when surplus food-producing nations choose to close trade as a defensive measure.”
Kropff added that many households in low-income countries depend on agriculture or related activities for their food and livelihoods. Their productivity and food security are compromised by illness or restrictions on movement or working.
“The call to action resonates with the findings of a landmark 2015 study by Lloyd’s of London,” he explained. “That work highlighted the fragility of global food systems in the event of coinciding shocks, an outcome that seems entirely possible now, given the health, cultural, and economic impacts of the COVID-19 pandemic.”
At the same time, the work of CIMMYT, other CGIAR centers, and their partners worldwide helps to stabilize food systems, according to Kropff.
“Our research outputs include high-yielding, climate-resilient crop varieties and more productive, profitable and sustainable farming methods,” he said. “These give farmers — and especially smallholders — the ingredients for more efficient and effective farming. They are grounded in reality through feedback from farmers and local partners, as well as socioeconomic studies on markets and value chains for food production, processing, and distribution.”
“Today, 7.8 billion humans exploit almost each and every ecosystem of the planet. Livestock have followed humans in most of these ecosystems and are now far more numerous than wild vertebrates,” Frederic Baudron, a systems agronomist at the International Maize and Wheat Improvement Centre, said in an interview. For example, there are 4.7 billion cattle, pigs, sheep and goats and 23.7 billion chickens on Earth. “We live on an increasingly ‘cultivated planet’, with new species assemblages and new opportunities for pathogens to move from one species to another.”
However, the biodiversity crisis is seldom considered a global issue and often not a pressing one, and conservationists say it isn’t written about as often as it should be. “Media coverage for the biodiversity crisis is eight-times lower than for the climate crisis”, according to Baudron. “We need to reduce the frequency of pandemics like COVID-19 by conserving and restoring biodiversity globally, most crucially in disease hotspots.”

While all eyes are on Lombardy, Madrid, New York and Wuhan, what do we know about the impact of COVID-19 on the rural poor and on food security in developing countries? How can the impact of the crisis be moderated? What positive breakthroughs could be provoked by this shock to move us into a better “new normal”? What can donors and implementing organizations do to support low- and middle-income countries during and beyond this crisis?
Members of the Agriculture and Rural Development working group of the international Scaling Up community of practice held a virtual meeting to discuss these questions and how scaling-up innovations could help to recover from the current crisis and mitigate future ones.
Poor rural communities are particularly vulnerable
When it comes to a highly contagious disease, being in a rural area sounds better than being in a busy city, but that is a deceptive impression. Smallholder farmers often are older than average and hence more vulnerable to the virus, and they have less access to health services.
They also depend on field laborers that are not able to travel from surrounding villages to help with planting, weeding and harvesting. To process crops, smallholder farmers need to transport crops to processing centers, which may be closed, as are the markets where they obtain agricultural inputs or sell farm products. Large international agrobusiness firms, which supply inputs and purchase local famers’ products may withdraw, at least temporarily, from the rural economies. There are already reports of farmers feeding cattle strawberries and broccoli in India, as they are unable to get their goods to the market.
Most farmers also depend on non-farm and off-farm activities for their livelihoods, as they may be field laborers for other farmers, work in the processing industry or work in construction. Interrupted transportation and closures pose serious challenges to maintain safe business continuity throughout the rural economy. The risk is not only that immediate rural production, food deliveries, exports, employment and incomes will collapse, but also that planting for next year’s crops will be disrupted.
It is key to differentiate between global and local supply chains, which will suffer in different ways. For example, in Uganda, supermarkets are open but small, informal markets are closed. In past crises, governments have focused on the survival of global value chains over local ones. Small, rural businesses are more likely to close permanently than large international ones.
Globally, international support for agriculture and rural development has been lagging in recent years. Today, the international support from aid agencies and NGOs is interrupted, as travels are restricted and community meetings are prohibited. With increased donor attention to a domestic and international health crisis, aid for rural communities may drop precipitously.

Opportunities for an improved “new normal” as we respond to the crisis
The short-term response to help minimize the impact of the COVID-19 crisis on the rural poor is critical, but we also need to support the shaping of a “new normal” where rural food systems are resilient, profitable and inclusive for poor rural communities. Members of the Scaling Up community of practice explored various ideas.
First, the COVID-19 pandemic could present opportunities to break silos and show how closely health and agriculture are related.
“COVID-19 cuts across sectors and jurisdictions in ways that single organizations and established governance structures are ill-equipped to accommodate,” said Larry Cooley, Scaling Expert and Founder and President Emeritus of Management Systems International (MSI)
For example, rural agricultural extension networks could be used to disseminate information on health awareness and education around COVID-19 and collect data on local impacts. This may cause and provide relief in the short term, but may also provide opportunities for collaboration in the long run.
“Our agricultural networks go deep into the rural areas and we are training our agri-entrepreneurs in India to disseminate health messages, products and services to help address COVID-19,” said Simon Winter, Executive Director of the Syngenta Foundation.
“At the African Development Bank we are providing emergency relief finance and re-purposing funding to have a link with COVID-19,” said Atsuko Toda, the bank’s Director of Agricultural Finance and Rural Development.
Second, a “new normal” could also mean an even stronger independence from externally funded projects, experts and solutions to more local ownership and expertise in rural areas, something that the community of practice has been promoting strongly. We could help to support more autonomy of the farmer, a strong local market and scale-up local value chains. Strengthening the capacity of small and medium enterprises linking farmers to urban markets could help ensure stability in future economic shocks.
“Governments and donor ‘projects’ looked too much at export and global value chains. I see great opportunities to scale up local and regional input and output value chains that benefit local farmers and small and medium enterprises,” said Margret Will, expert on value chains.
Third, the COVID-19 pandemic presents an opportunity to accelerate the scaling of innovations.
“Lack of access to labor could be disrupting harvesting and planting in our Feed the Future countries, accelerating an already predominant trend of migration, especially among the young, to urban areas. We see a looming need for mechanization of farms at scale, using mini-tillers, planters, harvesters and other time- and labor-saving equipment,” said Mark Huisenga, Senior Program Manager for the USAID Bureau for Resilience and Food Security.

Rural communities that use more ecological intensive practices, such as conservation agriculture and push-pull farming or safe storage practices are less dependent on external inputs and labor.
The current crisis forces us to use digital communication systems, replace human work with digital tools where possible and use technology to help target interventions. Both the public and private sector could build on this opportunity to invest in increased access to internet, electricity and other digital resources, including in impoverished areas. All these technological innovations can help farmers to better cope with the constraints of COVID-19 and any future crises or stresses to the food system, while also making agriculture more productive and more attractive to the young.
“The pandemic creates an opportunity to accelerate the use of digital technologies in smallholder agriculture, not only for extension advice but to crowdsource information about COVID-19 impacts,” said Julie Howard, Senior Advisor for the Center for Strategic and International Studies (CSIS).
Finally, COVID-19 will change our global governance system, and the agriculture, research and development sector has a role to play in this transformation. A systems change must focus on dietary diversity and food safety and security, paying attention to the rural poor in low- and middle-income countries. We can work together to scale cross-sector platforms to build solid networks and scale-up innovations to strengthen sustainable and resilient food systems.
Systems change beyond the agricultural sector, sustainability through local ownership and uptake of innovations that support profitable and resilient agricultural and related rural activities are key components of how the Scaling Up Community of Practice approaches scaling. A systems change is imminent, and it is important to support a transformation in a direction where local markets, rural labor and regional economies come out stronger in the long term. This requires vision, expertise, mobilization of resources, information sharing and crowdsourced leadership, and the network of scaling experts can contribute to this.
The Agriculture and Rural Development working group of the international Scaling Up community of practice is made up of individuals from more than 100 official donors, foundations, think tanks, research and development organizations united by their interest in scaling the impact of innovations on food security and rural poverty. Areas of particular interest for the group include designing for scale, using scaling frameworks, learning about scaling, responsible scaling, sustainability and system thinking. Members of the working group include professionals with vast experience from the field, and the group explicitly tries to learn from the application of complex concepts such as sustainability, systems change and scaling in real world settings by local actors. In addition to quarterly virtual meetings, the working group encourages and supports exchanges among its members on a variety of subjects. Participation in, and management of, the Agriculture and Rural Development working group is done on a purely voluntary basis.

While the world’s attention is focused on controlling COVID-19, evidence points at the biodiversity crisis as a leading factor in its emergence. At first glance, the two issues might seem unrelated, but disease outbreaks and degraded ecosystems are deeply connected. Frédéric Baudron, systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT) and Florian Liégeois, virologist at the Institut de Recherche pour le Développement (IRD) share their insights on the current COVID-19 crisis and the link between biodiversity loss and emerging infectious diseases.
What trends are we seeing with infectious diseases like COVID-19?
We see that outbreaks of infectious diseases are becoming more frequent, even when we account for the so-called “reporting bias”: surveillance of such events becoming better with time and surveillance being better funded in the North than in the South.
60% of infectious diseases are zoonotic, meaning that they are spread from animals to humans and 72% of these zoonoses originate from wildlife. COVID-19 is just the last in a long list of zoonoses originating from wildlife. Other recent outbreaks include SARS, Ebola, avian influenza and swine influenza. As human activities continue to disturb ecosystems worldwide, we are likely to see more pathogens crossing from wildlife to humans in the future. This should serve as a call to better manage our relationship with nature in general, and wildlife in particular.

Why are we seeing more cases of diseases crossing from animals to humans? Where are they coming from?
Evidence points to bushmeat trade and consumption as the likely driver for the emergence of COVID-19. The emergence of SARS and Ebola was also driven by bushmeat consumption and trade. However, when looking at past outbreaks of zoonoses caused by a pathogen with a wildlife origin, land use changes, generally due to changes in agricultural practices, has been the leading driver.
Pathogens tends to emerge in well known “disease hotspots,” which tend to be areas where high wildlife biodiversity overlaps with high population density. These hotspots also tend to be at lower latitude. Interestingly, many of these are located in regions where CIMMYT’s activities are concentrated: Central America, East Africa and South Asia. This, in addition to the fact that agricultural changes are a major driver of the emergence of zoonoses, means that CIMMYT researchers may have a role to play in preventing the next global pandemic.

How exactly does biodiversity loss and land use change cause an increase in zoonotic diseases?
There are at least three mechanisms at play. First, increased contact between wildlife and humans and their livestock because of encroachment in ecosystems. Second, selection of wildlife species most able to infect humans and/or their livestock — often rodents and bats — because they thrive in human-dominated landscapes. Third, more pathogens being carried by these surviving wildlife species in simplified ecosystems. Pathogens tend to be “diluted” in complex, undisturbed, ecosystems.
The fast increase in the population of humans and their livestock means that they are interacting more and more frequently with wildlife species and the pathogens they carry. Today, 7.8 billion humans exploit almost each and every ecosystem of the planet. Livestock have followed humans in most of these ecosystems and are now far more numerous than wild vertebrates: there are 4.7 billion cattle, pigs, sheep and goats and 23.7 billion chickens on Earth! We live on an increasingly “cultivated planet,” with new species assemblages and new opportunities for pathogens to move from one species to another.
Wildlife trade and bushmeat consumption have received a lot of attention as primary causes of the spread of these viruses. Why has there been so little discussion on the connection with biodiversity loss?
The problem of biodiversity loss as a driver of the emergence of zoonoses is a complex one: it doesn’t have a simple solution, such as banning wet markets in China. It’s difficult to communicate this issue effectively to the public. It’s easy to find support for ending bushmeat trade and consumption because it’s easy for the public to understand how these can lead to the emergence of zoonoses, and sources of bushmeat include emblematic species with public appeal, like apes and pangolins. Bushmeat trafficking and consumption also gives the public an easy way to shift the blame: this is a local, rather than global, issue and for most of us, a distant one.
There is an inconvenient truth in the biodiversity crisis: we all drive it through our consumption patterns. Think of your annual consumption of coffee, tea, chocolate, sugar, textiles, fish, etc. But the biodiversity crisis is often not perceived as a global issue, nor as a pressing one. Media coverage for the biodiversity crisis is eight times lower than for the climate crisis.

Agriculture is a major cause of land use change and biodiversity loss. What can farmers do to preserve biodiversity, without losing out on crop yields?
Farming practices that reduce the impact of agriculture on biodiversity are well known and form the foundation of sustainable intensification, for which CIMMYT has an entire program. A better question might be what we can do collectively to support them in doing so. Supportive policies, like replacing subsidies by incentives that promote sustainable intensification, and supportive markets, for example using certification and labeling, are part of the solution.
But these measures are likely to be insufficient alone, as a large share of the global food doesn’t enter the market, but is rather consumed by the small-scale family farmers who produce it.
Reducing the negative impact of food production on biodiversity is likely to require a global, concerted effort similar to the Paris Agreements for climate. As the COVID-19 pandemic is shocking the world, strong measures are likely to be taken globally to avoid the next pandemic. There is a risk that some of these measures will go too far and end up threatening rural livelihoods, especially the most vulnerable ones. For example, recommending “land sparing” — segregating human activities from nature by maximizing yield on areas as small as possible — is tempting to reduce the possibility of pathogen spillover from wildlife species to humans and livestock. But food production depends on ecosystem services supported by biodiversity, like soil fertility maintenance, pest control and pollination. These services are particularly important for small-scale family farmers who tend to use few external inputs.
How can we prevent pandemics like COVID-19 from happening again in the future?
There is little doubt that new pathogens will emerge. First and foremost, we need to be able to control emerging infectious diseases as early as possible. This requires increased investment in disease surveillance and in the health systems of the countries where the next infectious disease is most likely to emerge. In parallel, we also need to reduce the frequency of these outbreaks by conserving and restoring biodiversity globally, most crucially in disease hotspots.
Farming tends to be a major driver of biodiversity loss in these areas but is also a main source of livelihoods. The burden of reducing the impact of agriculture on biodiversity in disease hotspots cannot be left to local farmers, who tend to be poor small-scale farmers: it will have to be shared with the rest of us.
