Researchers urged to use common gender keywords to improve data impact
A common approach toward data structuring is needed to improve access to gender research across agriculture data repositories, a recent report by the CGIAR Platform on Big Data in Agriculture suggests.
Simply adding the keyword ‘gender’ in database descriptions will improve the findability of gender agricultural research, which currently is hard to find due to the inconsistent use of keywords and tagging, said the report’s author Marcelo Tyszler, a (gender) data expert with the Royal Tropical Institute (KIT) in the Netherlands.
“The data is there. We just can’t find it all! A lack of consistent keywords when tagging research is leading to holes in searches for gender research across CGIAR, the world’s largest network of agricultural researchers,” he says.
“A more systematic and sharper use of keywords when describing datasets will improve findability in searches,” Tyszler states.
As part of the Findability of Gender Datasets report, researchers used a range of keywords, including ‘gender’, ‘women’ and ‘female,’ to search repositories for gender-based data across CGIAR agricultural research centers and compared the search results with a reference list of gender datasets provided by scientists. The results showed that a number of the datasets in the reference list were not found using these search terms.
The results uncovered important inconsistencies in the description of gender research, especially in terms of how data is structured and the detail of documentation provided in CGIAR repositories, says co-author Ewen Le Borgne, a KIT gender researcher.
“Poor data management limits the impact of research to be found, read and incorporated into new research projects,” Le Borgne says, invoking the age old saying, “If a tree falls in a forest and no one is around to hear it, does it make a sound?”
The researchers used the findings to promote a standardized approach to tagging and describing their research.
“To improve findability and the impact of data, the gender community should develop a list of commonly agreed keywords that can be used to consistently describe gender research data sets,” Le Borgne explains.
Any dataset containing ‘sex-disaggregated’ data should indicate so in the keywords, said Tyszler. This is also important for non-gender researchers, to broaden the scope of their impact.
“By facilitating the tagging, findability and accessibility of quantitative and qualitative gender data we hope to facilitate mixed methods research by providing opportunities for both qualitative and quantitative researchers to exchange insights and create a stronger dialogue,” he explains.
Moreover, across the CGIAR there is a wealth of gender specific qualitative data collected through focus groups, interviews and other participatory research. As CGIAR continues to advance gender research efforts, big data is unearthing exciting opportunities for understanding and acting on the relationships among gender, agriculture, and rapidly digitizing economies and societies. However, varied approaches to data management is restricting access, thus limiting the impact data can have when other researchers aim to reuse results to gain deeper insights.
Moving beyond the ‘gender’ tag
Not surprisingly, ‘gender’ was the most common keyword used to describe data found in the study. Although it is essential for researchers to add the ‘gender’ keyword to research descriptions they must also go further in describing what the dataset represents, the researchers indicated.
“‘Gender’ is not precise enough a keyword to find all relevant gender-focused datasets. However, our search shows very few details as to what, about gender, is studied in each project,” says Tyszler.
Studies in other fields, for example nutrition, seem to have much more granularity in the description, with keywords including, nutrient intake, nutrition policy, micronutrient deficiencies, etc. We need a movement like this in gender research, he explained.
Better keywords should be a minimum, but it is also possible to consider the identification of a set of smart ‘gender metadata fields’. These would be input elements that need to be filled in that could ensure all CGIAR datasets properly assess gender dimensions, which would boost the visibility of gender research.
Working as part of the CGIAR Socio-Economic Data Community of Practice, the gender researchers support the exchange of gender-focused data collection tools, with standardized focus groups and interview questions, to improve the potential for comparing different datasets.
Since 2018, the CGIAR Platform for Big Data in Agriculture and CGIAR Collaborative Platform for Gender Research have been collaborating out of mutual interest, to identify ways to unlock the big data potential of gender research.
Together they aim to take a much more active role in shaping up how gender data can be better analysed and reveal new insights, said Gideon Kruseman, the lead of the CGIAR Socio-Economic Data Community of Practice.
“We are promoting a standardized approach by bringing together gender data experts with other socio-economic and even biophysical scientists that may not know how to best engage with gender research and data,” Kruseman explains.

Reaping the benefits of innovation
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 diversify crops in their fields and food on their plates
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.

Small but mighty
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 many colors of maize, the material of life
Tonahuixtla, a small town located in Mexico’s state of Puebla, had suffered extreme environmental degradation due to deforestation and erosion. Agricultural land was in poor condition and the town had stopped producing many of their heirloom maize varieties, a loss to both biodiversity in the region and local culture. Poverty had increased, forcing many to migrate to bigger cities or to the United States for work. Those who were left behind, most of them women, had few ways to generate income to support their families.
Today, the story of Tonahuixtla is different. The town actively participates in reforestation and erosion-prevention activities. Landrace maize production is increasing, preserving the town and region’s biodiversity and customs. The residents have job opportunities that allow them to stay in their town and not migrate, all while preserving local biodiversity and protecting the environment.
What caused this change?
Corn husks.
Long considered a waste product, corn husks have been given a new lease on life through the Totomoxtle project. Named for the traditional indigenous Nahuatl word for corn husk, Totomoxtle turns the husks of native maize, found in a variety of colors, into a beautiful and sustainable veneer for furniture and walls. Founded by Mexican graphic designer Fernando Laposse, Totomoxtle has given farmers an incentive to plant native maize again, preserving invaluable biodiversity for future generations.
When Denise Costich, head of the maize collection of the germplasm bank at the International Maize and Wheat Improvement Center (CIMMYT), heard about the Totomoxtle project she knew she wanted to help. Passionate about preserving native maize, she and her team identified 16 landrace varieties from the CIMMYT maize collection that would produce husks in interesting colors and could grow well in the altitude and climate conditions of Tonahuixtla. She invited Laposse and project members to come visit the genebank and learn about CIMMYT’s work, and provided them with seed of the landraces they had identified.
“This is what we normally do in our work at the germplasm bank, we give people seed,” Costich said. “But this turned into a closer collaboration.”
Colorful collaboration
The maize germplasm bank team arranged for Totomoxtle project members to receive training in how to make controlled pollinations in the native maize varieties, at one of CIMMYT’s experimental stations.
“The technicians at CIMMYT’s Agua Fria station loved meeting the project members from Tonahuixtla, and immediately became passionate about the Totomoxtle project,” Costich said. “To this day, the technicians still save all of the colored corn husks from CIMMYT maize trials and send them to Tonahuixtla to provide them with additional material for their project.”
In the village of Tonahuixtla, project members — many of them women — work to iron the corn husks flat and glue them on to a stiff backing, then send them via courier to Laposse’s workshop in London where he uses them to create beautiful furniture and wall panels. This work allows the residents of Tonahuixtla to stay in their village and not be forced to migrate, all while preserving maize biodiversity and protecting the environment.
“Part of what this project is doing is also helping to keep families together — providing livelihoods so that people can stay in their communities, so that they don’t have to send all of their young people off to Mexico City or to the United States. To me, it’s really all connected,” Costich said.

The value of sustainability
The project also shows the intersection between biodiversity conservation and protecting the local environment. The maize husks used for the project are a sustainable and biodegradable material, and any residue from the maize husks that are not used for the Totomoxtle project are either fed to animals in the dry season or used to make fertilizer, which is then returned to the maize fields, a completely circular cycle in which nothing is wasted.
“I think that many of the communities that we work in really do understand the value and the importance of biodiversity,” Costich said. “In Tonahuixtla, the people are trying to reforest the hillsides in their region. They understand the connection between having no vegetation on the hills and having the rain water just roll right off the hills and into the temporary streams, thus losing that critically important resource. Over the years, as a result of the work they have done there, they have seen with their own eyes the improvement in the environment, not only that the hills are now covered with vegetation, but also they see a lot less runoff and erosion. I think that’s a really important lesson for everyone. I come from an ecology background, so I am always very excited to get involved in projects where it’s not just about maize, it’s about everything. It’s also about people’s lives, and nutrition, and the connections between them.”
Preserving local maize biodiversity is not just important for Tonahuixtla — it is important to all of humanity. Native maize varieties have adapted for thousands of years in farmers’ fields across Mesoamerica, developing natural resistance to local plant pests and diseases, as well as climatic conditions such as heat or drought. These native maize seeds, passed down generation to generation, could hold the key to developing improved maize varieties that can resist emerging maize diseases or extreme weather events related to climate change. If this biodiversity is lost, it represents a loss to global food security as a whole.
CIMMYT works to protect many of these native maize varieties in their germplasm bank, which is home to over 28,000 different collections of maize. Kept in cold storage under optimum conditions in the CIMMYT seed vault, these seeds are preserved for future generations and are available to anyone who needs them, including farmers such as those in Tonahuixtla, who had lost much of their native maize diversity.
“The biodiversity of cultivated plants is basically the guarantee for the future,” Costich said. “This is our security backup. Seed security is food security.”

Two decades of illustrious service
After a long and distinguished service as a maize breeder and senior manager at the International Maize and Wheat Improvement Center (CIMMYT), Stephen Mugo has retired from the organization. A Principal Scientist and Maize Breeder at CIMMYT’s Global Maize Program, Mugo also served as CIMMYT’s Country Representative for Kenya and CIMMYT’s Regional Representative for Africa.
He joined CIMMYT in 1998 as a post-doctoral fellow and his last day of work was on May 31, 2020. His colleagues honored him with memorable tributes at an online meeting held on May 21, 2020.
“Mugo has always demonstrated his commitment and determination, even in the most challenging times, for the benefit of CIMMYT and its staff. He has been a very productive scientist, maize breeder and project leader of several projects that have had great impact in the past. We are proud of what he has been doing and still does for CIMMYT,” said Director General Martin Kropff.
In his illustrious career, Mugo led the Stress Tolerant Maize for Africa Supplement Project (STMA-SUP) and the TELA Maize Project, both of which aimed at improving maize for drought tolerance and insect pest resistance in five countries in eastern and southern Africa. He was also the CIMMYT leader for the Water Efficient Maize for Africa (WEMA) project (2008-2018), Insect Resistant Maize for Africa (IRMA) project (1999-2004) and the Strengthening Seed Systems project in Kenya and Uganda (2001-2003).
“I leave CIMMYT with fond memories and with my head held high. I sincerely wish to thank my colleagues for being a wonderful team that continues to work hard to ensure that we get the right seed to the farmer,” Mugo said. “I have enjoyed every bit of my time at the organization. What I would request is that for us to continue working well together, we need to respect and treat one another the way you would like to be treated. This way, the organization would move from strength to strength,” he expressed.
Mugo holds a PhD in Plant Breeding and Genetics from Cornell University and has published extensively in peer reviewed journals, with several book chapters to his name.
B.M. Prasanna, Director of the Global Maize Program at CIMMYT and the CGIAR Research Program on Maize (MAIZE) acknowledged the tremendous contribution that Mugo has made over the years in the projects he led.
“His work on the Insect Resistant Maize for Africa (IRMA) project has been phenomenally important, especially some of the germplasm that we are now finding as native genetic resistant to the fall armyworm,” Prasanna remarked. “He is a great champion and tremendous ambassador for CIMMYT’s work in Africa. I am sure he will continue to contribute to CIMMYT for years to come.”
Even though he leaves the stage, Mugo will provide consultancy support to CIMMYT, particularly on the MLN Gene Editing and TELA Maize projects.
Farm mechanization under COVID-19
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.
