Rajendra Kathariya, a 41-year-old resident of Joshipur-2 in Kailali district, far-west of Kathmandu, has transformed his life and that of his family of five through commercial agriculture. Despite many challenges, Rajendra has remained committed to achieving financial sustainability through enhanced farming practices. Over the last two years, his partnership with Nepal Seed and Fertilizer (NSAF) and CIMMYT, in collaboration with Nisrau Multipurpose Cooperative, a partner cooperative of NSAF, has been instrumental in his success.
Moving from traditional to modern farming
Previously, Rajendra cultivated cereal crops using traditional methods which often led to food crises for his family. However, he has now shifted to cultivating various crops throughout the year using modern farming techniques on his 1.02 ha of land and an additional 2.71 ha which he has leased.
“Before NSAF’s support, we only cultivated two crops per year. Now we harvest three crops and are considering commercial maize production,” Rajendra said.
Remarkable achievements in crop production
Last year, Rajendra cultivated rice on 3.72 ha, yielding 8.8 metric tons (t) worth NPR 250,000 (US $1,880.71). Similarly, he sold 3.8t of spring maize from 1.35 ha, earning NPR 110,000 (US $827.51). This year, he expanded maize cultivation to 2.03 ha, with an expected income of NPR 200,000 (US $1,504.57). His potato crop yielded 5.5t worth NPR 125,000 (US $940.35), with an additional 5.5t stored for future sale.
In addition to crops, Rajendra has established a pig farm, earning NPR 400,000 (US $3,009.13) in 2023 from selling pigs. He received a feed-making machine for pigs from NSAF, under its support to agribusiness Micro, Small and Medium Enterprises (MSMEs).
Embracing modern technology and techniques
Rajendra uses both organic and chemical fertilizers and follows improved farming techniques such as hybrid seeds, line sowing, and machinery use. He owns a mini tiller and rents other machinery as needed. This year, with support from NSAF, he used a drone to spray fertilizer on his spring maize, significantly reducing labor and time.
“I have viewed videos of drones spraying fertilizer but never imagined it happening on my spring maize land. As a demonstration, 0.57 ha was used for nano urea spraying. The task was completed within five minutes of the drone taking flight. Similarly, I was astonished to learn that a drone can cover 2.02 ha in a mere 20 minutes,” he shared.
Intercropping and future plans
Rajendra has also implemented intercropping, combining maize with legumes on a 0.10-hectare plot. “Spring maize-legume intercropping is productive and effective for farmers such as me. We can make a profit from legumes, as well as spring maize. I will continue using this practice in the future,” he said.
Financial investments and community impact
The profits from agriculture have helped Rajendra to manage his household comfortably. He can now provide education for his four children, manage household expenses, and also pay the loan that he had taken for his household expenses. In addition, he recently invested NPR 250,000 (US $1,880.71) to build a new pig shed. He also sells his produce in local markets at Joshipur, Kailali.
“I have travelled a long way from being a subsistence farmer to engaging in commercial farming. This shift from traditional to improved farming technologies has been made possible with the support of NSAF/CIMMYT. I am grateful for their assistance and encouragement,” Rajendra said.
Vision for sustainability
Rajendra’s story reflects his dedication and hard work. “I was working as a daily wage laborer in India, hoping to secure a promising future for my children. Today, I can achieve complete sustainability through agriculture and provide quality education and a better life for my children,” he shared.

Farmers, stakeholders, and partners, including seed companies, Hamara Chicks, PHI Commodities, the International Livestock Research Institute (ILRI), BioHUB Trust (BHT), Kurima Machinery and Technology, and Zimplow Limited, participated in the Seed and Livestock Fair in the Mbire and Murewa districts of Zimbabwe, which showcased indigenous and improved seed varieties and different technologies to strengthen crop and livestock value chain systems.
Initiated by CIMMYT in 2022, as the CGIAR Initiative on Agroecology, these series of fairs have become instrumental in bringing agrodealers closer to farmers and showcasing sustainable technologies and innovations that have the potential to strengthen production systems. It was also an opportunity for the agroecology initiative team to provide feedback to farmers and stakeholders on ongoing activities and technologies that were being tested since the initiative’s inception in Zimbabwe. By adopting a multi-partner approach, these fairs bring local food systems actors together to ensure food and nutrition security and improved income for farmers.
“The agroecology initiative has been collaborating with an array of organizations and institutes that can support our mission towards promoting agroecology and improving farming production, including other CGAIR entities like IWMI and ILRI, Hamara Group, Ecolyfe, and PHI Commodities,” said Dorcas Matangi, research associate at CIMMYT.
This year’s edition of the seed and livestock fair “Fostering Synergies: Diverse Crops, Livestock and Inclusive Communities” advocated for enhancing synergies within the farm to foster sustainable agroecology transitions for resilient food and nutrition outcomes. With over 800 farmers and stakeholders participating, the event provided a vibrant platform for knowledge sharing, exploration of indigenous and improved seed varieties, and sensitization of innovative technologies.
“The seed and livestock fairs hosted by the agroecology initiative bring together farmers and food system actors from all walks of life to foster learning around agroecology, which includes the importance of diversity (crop and livestock) while also appreciating local innovations in the respective area,” said Jesca Mapfinya, a Murewa farmer.
The right seed, assures a good harvest
Various seed companies participated in the fair to showcase different seeds which are well adapted in Murewa and Mbire districts. Each agroecological region in Zimbabwe is unique, with adaptable seed varieties that are either landrace or improved. Local landraces and many underutilized crop species are adapted to weather and climate variability, climate change, and extreme weather such as drought and heat stress. Farmers indicated that their motivations for growing landraces are related to sustainable farming systems suitable for social, cultural, nutritional, and agronomic traits. Their place in rural communities remains important, providing much-needed functional diversity and social capital. Including improved varieties within the basket of options can further intensify production systems in these communities.
“Primarily, we sell seed varieties and build farmer capacity around appropriate agronomic practices. The seed fairs are a good platform to match seeds and systems and allows a farmer to provide feedback about our seed varieties and how they are performing in the respective areas,” said Onesmous Satenga, SeedCo.

Building crop and livestock synergies
For the first time since the inception of the fairs, livestock such as cattle, sheep, goats, chicken and rabbits were displayed. Partners, including ILRI and the Hamara Chicks, who are into sasso chicken and feed production, reiterated the importance of crop diversity for improved livestock nutrition. ILRI and the Grasslands Research Institute exhibited various local feedstocks and alternative livestock feed grasses and also presented several feed formulations. Farmers also provided feedback on the feeding strategies employed for different livestock.
“We feed cattle with poultry litter, maize grain, maize stover, and groundnut shells in various proportions depending on the availability of these feed sources. Forage legumes such as velvet bean (mucuna pruriens) and lablab (lablab purpureus) have been introduced, and we have started to grow these for feed,” said Samson Tashaya, Murewa farmer.

Of keen interest to farmers and stakeholders was the sasso breed of chickens that the Hamara Group was promoting.
“We have recently joined as partners with CIMMYT and are promoting hybrid chicken production, especially sasso, here in Murewa ward 27 and 4. This is our first time coming to this seed fair, and it was a learning opportunity. The interactions with farmers were really good,” said Alan Norton, team leader at Hamara Chicks.
Modernizing smallholder production systems
Mechanization experts from Kurima Machinery and Zimplow shared their recommendations at the fair. They acknowledged that farmers rely heavily on scarcely available labor and production activities that are backbreaking. They advocated for modern production systems to produce more food and support economic transformation. Experts from Kurima Machinery and Zimplow demonstrated several machines that could aid farmers in various on-farm activities.
“This fair has come at the right time as I begin land preparation for my pfumvudza (conservation agriculture plots). I have seen how the basin digger works, and I am keen to purchase an instrument to make my work much easier,” said Chief Chisunga, Mbire.
“This crop season’s outlook is still unclear, but weather experts have warned of an intense El Nino event likely to happen in the second half of the season. Technologies such as conservation agriculture can ensure good moisture retention in crop fields, and it needs to be paired with good agronomic practices,” said Tafadzwanashe Mabhaudhi, climate and food systems expert.

Smallholder mechanization out scaling depends upon the availability of skilled mechanics who are fully oriented with machinery operation. However, this crucial skillset is often identified as a missing link. In many instances, lack of care or regular checks and the absence of readily available mechanics has led to the failure of mechanization projects in sub-Saharan Africa, with frequent machine breakdowns and equipment left sitting idle long after a project intervention. Across smallholder farming communities, this phenomenon can be seen through the presence of obsolete and abandoned machinery often serving as breeding grounds for birds.
The Feed the Future Zimbabwe Mechanization and Extension Activity, funded by the United States Agency for International Development (USAID), aims to break this vicious cycle by improving the skillset of local mechanics and helping them stay in tune with evolving innovations in farm machinery. Implemented by CIMMYT, this activity targets existing mechanics across ten districts in Zimbabwe, offering specialized maintenance services to providers who own machinery. Through investing in their training, local capacity to troubleshoot, service and repair machinery will increase.

Gaining practical experience
The program approaches training through full immersion and a deep dive into the individual components of key equipment. Workstations are set up to include a diesel engine—which forms the core of most of the machinery—a two-wheel tractor and post-harvest machines such as the multi-crop thresher, feed-chopper grinder and peanut butter machine. For most of the participants, the workshop presents them with first-hand experience of handling such machinery.
Andy Chagudhuma and Tendai Machonesa—from Bikita and Chiredzi, respectively—were among the first ten mechanics to participate in the five-day training. “I learned about all the machines here,” says Chagudhuma, “breaking them apart and fixing them. We worked through different scenarios while perfecting our knowledge on the operation of all the machinery.” With new skills gained, they eagerly await the opportunity to offer their expertise to service providers in their local areas, and a newfound confidence fuels their commitment to providing support through repair and maintenance work.
However, one remaining challenge is the notable absence of female participants in the training. While the field of mechanics is often male-dominated, the Mechanization Activity seeks to promote a gender-inclusive environment for local mechanics and service providers through awareness meetings and skills training. In the future, more machinery and technical trainings will be targeted specifically towards women as a way to redress this imbalance.
Overall, the benefits of the training echo far beyond the workshop itself. Through the skills acquired, opportunities for additional income generation increase, and the participation of rural youths in mechanization-oriented businesses and a thriving local economy are possible. By empowering local mechanics, the Mechanization Activity not only breathes life into their communities and the machinery sector but also paves the way for one of the project’s key objectives—the establishment of successful and entrepreneurial service providers.
Mathuli drew attention to the innovations that are making her life easier, such as drought-tolerant maize seed varieties developed by the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agriculture and Livestock Research Organization (KALRO). She also cited her mobile phone as a vital tool, allowing her access essential information, such as weather forecasts, market prices, and technical farming support.
“In sub-Saharan Africa, more than half of the population works in agriculture,” explains Gates. “Together, they produce about 80 percent of the continent’s food supply. And most of the people doing the backbreaking farm work—like the chores I performed—are women.”
In addition to managing her farm, Mathuli is a model farmer and Village Based Advisor with the Cereal Growers Association, encouraging other farmers to adopt new practices that will improve their productivity. “She is clearly doing a good job in this role because more than 90 percent of farmers in her area have embraced one of the new adaptation practices,” said Gates.

Smallholder farmers in resource-poor communities of Zimbabwe and much of the Global South have been experiencing low crop productivity due to many factors, including inappropriate seeds and seed varieties, labor shortages, loss of agro-biodiversity, insufficient inputs, degrading soils, and recurrent droughts. These threats are now amplified by climate change.
This has resulted in broken food systems rendering food and nutrition insecurity commonplace. The One CGIAR initiative, Transformational Agroecology Across Food, Land, and Water Systems, led by the International Maize and Wheat Improvement Center (CIMMYT) in Zimbabwe, is designed to bring agroecological advances to smallholder famers in an effort to strengthen local food systems.
Smallholder farmers in the Mbire and Murehwa Districts of Zimbabwe were introduced to innovative agroecology interventions, premised on harnessing nature’s goods and services while minimizing adverse environmental impacts and improving farmer-consumer connectivity, knowledge co-creation, and inclusive relationships among food system actors.

Farmer to farmer collaboration at seed fairs
In response to challenges related to lack of appropriate seeds and eroding agrobiodiversity and, as a way to transition prevailing food systems to more sustainable ones, farmers were invited to take part in seed fairs. The seed fair’s objective was to enable smallholder farmers to access improved and locally adapted seeds of food crops originating from the private sector and fellow farmers. In addition, the seed fairs provided a platform for learning about agroecological practices. Farmers were also given a chance to see different machinery that could aid in land, food, and feed preparation, and address their labor shortage challenges.
At the opening of the seed fair in Mbire, Dorcas Matangi, CIMMYT research associate, acknowledged that smallholder farmers operate in challenging and complex ecological, social, and economic systems and there is a need for interventions that address the natural resource base without ignoring the social and economic dynamics within communities.
“The communal culture of sharing and trading between community members can be capitalized on for a collective benefit, said Matangi. “One such case is through events such as seed fairs where we encourage farmers to showcase and sell seeds they know perform very well.”
She further explained to the participating farmers how increasing their crop diversity and using practices such as conservation agriculture techniques benefit the environment and improves food security and nutrition.
“I am grateful for these efforts,” said Grace Musandaira, supervisor of the Agriculture Advisory and Rural Development Service. “Our region is arid, and as such, it is very difficult for our farmers to achieve significant yields to assure them there is enough food for the year. In addition, the knowledge provision relating to preserving and improving agrobiodiversity through agroecological practices is set to improve rural livelihoods.”
Senzeni Nyagonye, a farmer in Mbire, said “This initiative is teaching and exposing us to so many new concepts such as conservation agriculture with mechanization. If we can apply conservation agriculture with the seeds we bought at this seed fair, we are optimistic about a great harvest.”
A total of 1,058 farmers attended two seed fairs in Mbire and Murehwa. Farmers had the opportunity to access a variety of crop seeds ranging from maize, to sorghum, millets, groundnuts, bambara groundnuts, and sunflowers. More than 200 farmers exhibited local seeds that were available for sale or exchange. Private seed companies also showcased and sold certified drought-tolerant maize, sorghum, bean and cowpea varieties.
“The seed fairs in Mbire and Murehwa were very successful”, said Matangi. “And we feel these efforts will serve as a useful case study to guide a national scale-up.”
In the summer monsoon season preceding planting in the winter, farmers typically use low-density polyethylene (LDPE) bags contained within woven polypropylene bags to store their wheat seed. Seed quality typically deteriorates over the monsoon as a result of increased seed moisture and pests that are associated with high humidity and temperature.
After initially being consulted by survey and detailed focus group interactions on the design of the trial, 80 wheat farming households participated in a 30-week action research process by conducting trials to compare seed storage methods. This included comparing hermetic SuperGrainbags® (Premium RZ) against LDPE bags, both with and without the addition of dried neem tree leaves (Azadirachta indica), the latter representing a common method used by farmers in Bangladesh to improved stored seed.
Results of the trials demonstrated that seed germination and seedling coleoptile length were greater, and that seed moisture was maintained at levels close to before storage in SuperGrainbags® compared to LDPE bags. The use of neem however had no effect on these factors.
Furthermore, hermetic bags were more effective in lessening seed damage caused during the storage process, but neem slightly reduced damage rates for seeds stored using traditional methods compared to SuperGrainbags®.
In relation to diseases and pests, SuperGrainbags® suppressed Coleopteran pests and blackspot, while storing neem alongside the seeds in LDPE bags had a slight additional pest suppressive effect.
Scoring by both men and women farmers revealed their preference for SuperGrainbags® hermetic storage. The study recommends actions for value chain development to increase farmers’ access to improved hermetic storage options at low cost.

The paired challenges of population growth and climate change have put smallholder farmers in Zambia in a squeeze. In the Southern Province, the center of agricultural production for the nation, smallholder dairy farmers struggle to increase their production of fodder to commercially viable levels in the face of a long dry season that climate change is intensifying.
Smallholder farmers looking to support their families, enhance the local food supply, and sustain economic growth in their areas are at a distinct disadvantage because agriculture in Zambia is dominated by massive commercial operations with plentiful capital, large tracts of land, and expensive machinery, with most of their output marked for export.
The International Maize and Wheat Improvement Center (CIMMYT) is partnering with the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the University of Hohenheim to identify key barriers and sustainable pathways to smallholder farmer success through a mechanization working group. This work is being carried out through the global initiative One World No Hunger, which launched Green Innovation Centers for the Agriculture and Food Sector (GIC) in 15 member countries in 2014.
“Mechanization is a critical aspect of responding to these problems and the core business of the GIC is to develop knowledge,” said Chimuka Mulowa, a GIC cooperative development advisor based in Choma, Zambia. “Our efforts provide training to smallholder farmers with a focus on adaptive mechanization as a critical ingredient in a holistic approach. Projects in the past have purchased equipment, but we integrate knowledge with existing infrastructure.”

In Zambia, the GIC works with 22 cooperatives to reach 10,000 small-scale farmers with training sessions on fencing land to grow grass, climate smart breeding, irrigation, and more. The GIC has reached their training goal, but implementation of new practices has been more difficult, with only about half the farmers adopting what they have learned so far.
To better understand the challenges smallholder farmers face in Zambia, Mulowa and the GIC partnered with researcher Vuyo Maphango, who was completing his master’s degree in agricultural economics at the University of Hohenheim under the supervision of Lennart Woltering, a senior scientist at CIMMYT. Woltering developed a tool called Scaling Scan which analyzes barriers to growth for successful innovations in the pilot stage and brings focus to key ingredients for expansion.
Mulowa and Maphango used Scaling Scan to assess the progress of the GIC efforts in Zambia. As they expected, for smallholder farmers trying to get into commercial fodder production, financing was a challenge. At $35,000 USD for a machinery like hay balers used once per year, it can take a farmer up to a decade to recoup such an investment. But Scaling Scan also identified surprising challenges, such as a lack of collaboration and uneven dissemination of knowledge and skills.
“There was a lot of progress coming out of the Scaling Scan process,” Maphango said. “Growing the cooperatives of farmers is a critical GIC focus now, and this helps with the finance issues as well. Where farmers can’t afford to buy or develop high-quality seed, they can come together, share which seeds are working best for them, and help each other adopt best practices. Staying close as a cooperative also gives farmers stronger bargaining power with the ability to pool together finances.”
More affordable equipment will also help. Smaller, less expensive choppers and chuff cutters ($1500-2000 USD) are already available for silage production, but there is not a well-established tradition of employing silage production in Zambia, and farmers there have struggled to adopt it. Similar machines are making their way onto the market for fodder production and will require farmers to develop a new set of technical skills.
Mulowa and Maphango are also rethinking approaches to training. As an incentive, non-government organizations (NGOs) often pay participants for their time when they attend training sessions, but government ministries can’t sustain this practice beyond the end of a project due to lack of funding. For a deeper level of skill and knowledge development, GIC wants to help farmers see the benefit of training as providing its own incentive–continuing professional education will pay off, both in terms of better agricultural and business practices, and better financial outcomes. The key to this transition is results. When farmers see their yield improving because of skills and practices they developed in training, they will be hungry for more.
Success, for Zambian smallholders, is a door that is opening slowly but surely. “Early adopters are making progress,” Maphango said. “Some are growing their own grass, others are fencing their land and developing irrigation.” As these practices take root, and farmers share victories with cooperative members; the value of ongoing training becomes clear, and the door may open further for others to walk through.

Women’s involvement in maize production is often shrouded in assumptions. One might assume that women have minimal say in management decisions, especially regarding jointly managed plots, due to rigid gender norms that prioritize men’s decisions on farming-related matters. However, operating under such assumptions about women’s role in the management of maize farms risks confining women to specific roles and not meeting their needs in the maize seed system.
To break these assumptions, Rachel Voss, Gender Specialist at the International Maize and Wheat Improvement Center (CIMMYT), and a team of fellow researchers are conducting a study, “Unpacking maize plot management roles of women and men in smallholder households in Kenya.” The study, part of the Accelerating Genetic Gains in Maize and Wheat (AGG) project, aims to asses the gender dynamics of maize management in Kenya in order to categorize plots and households, analyzing intrahousehold decision-making and evaluating which women have the power and agency to apply their preferences for seed on their farms — and which ones do not.
Challenging perceptions
Take, for example, Sofa Eshiali, a 60-year-old farmer from Ikolomani, western Kenya, who participated in the study. She defies the stereotype of women having a limited role in maize farming, as she is deeply involved in decision-making on maize production in her household and represents an important client for new breeding efforts and more inclusive seed distribution programs. Together with her husband, she has grown maize primarily for family consumption since getting married, getting involved in all matters concerning their half acre farm. “For us, when we want to plant [our maize seeds], we sit together and discuss the cash we have at hand and decide if we can get two hands to help us work our half acre of land,” she says.
Eshiali and her husband make a joint decision on the maize seed variety they plant every season based on performance of the previous planting season. “We previously used the H614D [maize seed variety] and it did well in our farm — except when it gets very windy, as our crops fall and our bean crop gets destroyed before it is ready for harvest. Last season, we decided to use the H624 because it remains there even when it is windy,” she said, demonstrating her knowledge of maize seed variety.
In addition to seed choice and farm labour, Eshiali and her husband also discuss what fertilizer to use and when they need to shift to a new choice, and they make decisions together concerning their farm and farm produce. This includes deciding what amount of harvest they can sell and what to do with the sale proceeds. For a household like Eshiali’s, new maize varieties need to appeal to — and be marketed to — both spouses.

Farming roles
Eshiali’s reality of equitable engagement in the farm may not be the case for other households in her community and across Kenya, meaning that reaching women with new varieties is not always simple.
As Voss points out, women are often less involved in major household decisions than men, frequently due to longstanding social norms. However, there is little understanding of how decisions are negotiated at the household level, particularly when crops are jointly produced. Furthermore, in many places, men are perceived to be the “real” farmers, while women are viewed to only play a supportive role within household farming. This can lead to the exclusion of women from extension activities, trainings and input marketing efforts.
Against this background, Voss notes that the ongoing study aims to identify in which types of households women have control over seed choice and in which households other constraints might be more important.
“To get new maize varieties into men’s and women’s fields, we need to identify the bottlenecks to reaching women. This means understanding, among other things, how decisions about seed are made within households and how households source their seed,” she explains.

Best-case scenario
To overcome the challenge of discussing the sensitive topic of decision-making roles between spouses and to encourage more culturally unbiased, candid responses, the study uses vignettes, or short stories, to describe various scenarios. This enables farmers to relate with different farm management decision making scenarios without pointing fingers at their spouses.
The study’s coauthor and research team leader, Zachary Gitonga, explains that the use of vignettes is still a relatively new method, especially in agricultural research, but enables digging deeper into sensitive topics.
Data collection involved a joint survey with both men and women household heads about maize plot management before breaking into separate discussions using the vignettes. These presented five possible decision-making scenarios with fictitious husband and wife characters. The five scenarios were then used to discuss strategic seed choices, operational decisions related to issues such as planting date and hiring farm labor, and financial decisions such as the use of the income from the maize sales.
“By presenting a set of short stories, a farmer can determine what scenario they relate with. In the study, farmers can talk about sensitive interaction without having to assign responsibility to their spouse, especially negatively, in the way decisions are made,” Gitonga said.
The vignettes also made it easier for both the enumerators to explain the scenarios and the farmers to understand and freely give their feedback. Sometimes, he pointed out, what men and women perceive as joint decision-making might not be the same. For instance, some men may think informing their wives that they are going to buy a particular seed means involving them. Here, the vignette activity aims to unpack the reality of joint decision-making in households.
From East Africa to Asia
During a recent field visit to the study area in Kakamega, Kenya, Hom Gartaula, Gender and Social Inclusion Research Lead at CIMMYT, noted the study’s importance to the inclusion of women in the farming cycle. “We urgently need to better understand the reality of women’s and men’s situation in terms of access to maize seed and other needed inputs and services. Otherwise, we risk designing breeding and seed systems that do not address the needs of the most vulnerable farmers, including women,” he said, adding that data from the study will enable insights into and comparison with the gender dynamics of wheat production in South Asia through cross-regional learning.
Gartaula also noted that, even though men predominantly manage South Asia’s wheat agriculture, women significantly contribute to it, especially in smallholder farming systems. In recent years, women’s contribution to providing labor and decision-making in wheat agriculture has increased due to the feminization of agriculture and livelihood diversification among smallholders.
Since women’s contributions to wheat farming are often vital to pre- and post-harvest processes, Gartaula notes they ought to be part of the entire maize and wheat value chain. That includes building more equitable seed delivery systems. “It is therefore important to have seed products that address the needs of different users and include home consumption and commercial sales,” he says.
The study will inform future efforts to ensure equitable seed access for both men and women farmers. Ultimately, if both men and women farmers access the best seed based on their needs and priorities, incomes will rise, households will be better sustained, and communities will become more food secure.
For over a decade, the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT) have been at the forefront of research-for-development benefiting maize and wheat farmers in the Global South, especially those most vulnerable to the shocks of a changing climate.
From 2012 to 2021, MAIZE has focused on doubling maize productivity and increasing incomes and livelihood opportunities from sustainable maize-based farming systems. Through MAIZE, scientists released over 650 elite, high-yielding maize varieties stacked with climate adaptive, nutrition enhancing, and pest and disease resistant traits.
The WHEAT program has worked to improve sustainable production and incomes for wheat farmers, especially smallholders, through collaboration, cutting-edge science and field-level research. Jointly with partners, WHEAT scientists released 880 high-yielding, disease- and pest-resistant, climate-resilient and nutritious varieties in 59 countries over the life of the program.
To document and share this legacy, the MAIZE and WHEAT websites have been redesigned to highlight the accomplishments of the programs and to capture their impact across the five main CGIAR Impact Areas: nutrition, poverty, gender, climate and the environment.
We invite you to visit these visually rich, sites to view the global impact of MAIZE and WHEAT, and how this essential work will continue in the future.
CIMMYT’s relationship with Mexico is one of a kind: in addition to being the birthplace of the wheat innovations that led to the Green Revolution and the founding of CGIAR, Mexico is also where maize originated thousands of years ago, becoming an emblem of the country’s economy and identity.
Honoring this longstanding connection and celebrating Mexico’s key contribution to global wheat and maize production, Mexico City will host a photo exhibition from December 1, 2021, to January 15, 2022, in the Open Galleries Lateral, located on Paseo de la Reforma, one of city’s most iconic promenades.
Titled “Maize and Wheat Research in Focus: Celebrating a Decade of Research for Sustainable Agricultural Development Under the CGIAR Research Programs on Maize and Wheat,” the exhibition illustrates the impact of MAIZE and WHEAT over the last ten years. The selection of photographs documents the challenges faced by maize and wheat smallholders in different regions, and showcases innovative interventions made by national and regional stakeholders worldwide.
From pathbreaking breeding research on climate-smart varieties to helping farming families raise their incomes, the photos — taken by CGIAR photographers before the COVID-19 pandemic — capture both the breadth of the challenges facing our global agri-food systems and the spirit of innovation and cooperation to meet them head on.
Don’t miss the chance to visit the exhibition if you are in Mexico City!

From October 31 to November 12, all eyes and cameras turned to Glasgow, where the 26th Conference of the Parties of the United Nations Convention against Climate Change (COP26) took place in a hybrid format. With temperatures rising around the world and extreme weather events becoming increasingly frequent, country leaders and climate experts came together in Scotland to discuss the next steps in the fight against climate change.
Together with other CGIAR Centers, the International Maize and Wheat Improvement Center (CIMMYT) took part in this crucial conversation, drawing attention to the impact of climate change on smallholder agriculture and echoing CGIAR’s call for increased funding for agricultural research and innovation.
Here’s a summary of the events in which CIMMYT researchers and scientists participated.
“Because farmers feed us all: using climate for a resilient food system”
November 6, 2021
Sponsored by the UK Met Office, this event focused on the effects of climate change on the resilience of food systems and how this impact is factored into decision-making. Speakers discussed the real-life application of climate risk information, highlighting the importance of global collaboration and multi-stakeholder partnerships in developing context-specific climate services.
Focusing on CIMMYT’s work in Ethiopia, research associate Yoseph Alemayehu and senior scientist Dave Hodson provided some insights on the wheat rust early warning system. This revolutionary mechanism developed by CIMMYT and partners helps farmers in developing countries predict this disease up to a week in advance.
“COP26 highlighted the vulnerability of different agriculture sectors to climate change, including increased threats from pests and pathogens. From the work in Ethiopia on wheat rust early warning systems, strong partnerships and the application of advanced climate science can play an important role in mitigating some of the effects.” – Dave Hodson
“Developing Climate Resilient Food Systems Pathways: Approaches From Sub-Saharan Africa”

Putting an emphasis on participatory governance and community-centered technologies, this event showcased innovative approaches to strengthen the resilience of African food systems, calling for increased investment in the scale-up of climate-smart agriculture practices to meet growing demand.
Joining from Zimbabwe, Christian Thierfelder, Principal Cropping Systems Agronomist gave an overview of CIMMYT’s work in southern Africa, explaining how the introduction of conservation agriculture back in 2004 helped farmers overcome low crop yields and boost their incomes.
“If one thing was made clear at COP26, it is the urgent need for a change in the way we do agriculture. The status quo is not an option and we, as CIMMYT and part of the One CGIAR, will continue to generate the scientific evidence and climate-smart solutions to accelerate this change and address the climate challenges ahead of us, with farmers at the core of our work.” – Christian Thierfelder
“4 per 1000” Initiative Day
November 10, 2021
The “4 per 1000” Initiative, a multi-stakeholder partnership of more than 650 members on food security and climate change, held a day-long hybrid event to explore how healthy soils can help agriculture and forestry adapt to and mitigate climate change.
At the Partner Forum, Bram Govaerts, Director General of CIMMYT, stressed the urgent need to fund soil science to achieve its carbon sequestration potential, reiterating CIMMYT’s commitment to supporting this science with results-oriented actions that scale out sustainable practices and technologies.
“For me, the main take-away of the summit is the growing consensus and understanding that we need to transform agriculture and food systems to achieve global emissions targets on time.” – Bram Govaerts

Given the very heterogeneous conditions in smallholder agriculture in sub-Saharan Africa, there is a growing policy interest in site-specific extension advice and the use of related digital tools. However, empirical ex ante studies on the design of this type of tools are scant and little is known about their impact on site-specific extension advice.
In partnership with Oyakhilomen Oyinbo and colleagues at KU Leuven, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have carried out research to clarify user preferences for tailored nutrient management advice and decision-support tools. The studies also evaluated the impact of targeted fertilizer recommendations enabled by such tools.
Understanding farmers’ adoption
A better understanding of farmers’ and extension agents’ preferences may help to optimize the design of digital decision-support tools.
Oyinbo and co-authors conducted a study among 792 farming households in northern Nigeria, to examine farmers’ preferences for maize intensification in the context of site-specific extension advice using digital tools.
Overall, farmers were favorably disposed to switch from general fertilizer use recommendations to targeted nutrient management recommendations for maize intensification enabled by decision-support tools. This lends credence to the inclusion of digital tools in agricultural extension. The study also showed that farmers have heterogeneous preferences for targeted fertilizer recommendations, depending on their resources, sensitivity to risk and access to services.
The authors identified two groups of farmers with different preference patterns: a first group described as “strong potential adopters of site-specific extension recommendations for more intensified maize production” and a second group as “weak potential adopters.” While the two groups of farmers are willing to accept some yield variability for a higher average yield, the trade-off is on average larger for the first group, who have more resources and are less sensitive to risk.
The author recommended that decision-support tools include information on the riskiness of expected investment returns and flexibility in switching between low- and high-risk recommendations. This design improvement will help farmers to make better informed decisions.

Using data from a discrete choice experiment, the study showed that extension agents were generally willing to accept the use of digital decision-support tools for site‐specific fertilizer recommendations. While extension agents in the sample preferred tools with a more user‐friendly interface that required less time to generate an output, the authors also found substantial preference heterogeneity for other design features. Some extension agents cared more about the outputs, such as information accuracy and level of detail, while others prioritized practical features such as the tool’s platform, language or interface.
According to the authors, accounting for such variety of preferences into the design of decision-support tools may facilitate their adoption by extension agents and, in turn, enhance their impact in farmars’ agricultural production decisions.

Impact of digital tools
Traditional extension systems in sub-Saharan African countries, including Nigeria, often provide general fertilizer use recommendations which do not account for the substantial variation in production conditions. Such blanket recommendations are typically accompanied by point estimates of expected agronomic responses and associated economic returns, but they do not provide any information on the variability of the expected returns associated with output price risk.
Policymakers need a better understanding of how new digital agronomy tools for tailored recommendations affect the performance of smallholder farms in developing countries.
To contribute to the nascent empirical literature on this topic, Oyinbo and colleagues evaluated the impact of a nutrient management decision-support tool for maize – Nutrient Expert — on fertilizer use, management practices, yields and net revenues. The authors also evaluated the impacts of providing information about variability in expected investment returns.
To provide rigorous evidence, the authors conducted a three-year randomized controlled trial among 792 maize-producing households in northern Nigeria. The trial included two treatment groups who are exposed to site-specific fertilizer recommendations through decision-support tools — one with and another one without additional information on variability in expected returns — and a control group who received general fertilizer use recommendations.
Overall, the use of nutrient management decision-support tools resulted in greater fertilizer investments and better grain yields compared with controls. Maize grain yield increased by 19% and net revenue increased by 14% after two years of the interventions. Fertilizer investments only increased significantly among the farmers who received additional information on the variability in expected investment returns.
The findings suggest including site-specific decision support tools into extension programming and related policy interventions has potential benefits on maize yields and food security, particularly when such tools also supply information on the distribution of expected returns to given investment recommendations.
The research-for-development community has tried different approaches to optimize fertilizer recommendations. In Nigeria, there are several tools available to generate location-specific fertilizer recommendations, including Nutrient Expert. As part of the Taking Maize Agronomy to Scale in Africa (TAMASA) project, CIMMYT has been working on locally calibrated versions of this tool for maize farmers in Ethiopia, Nigeria and Tanzania. The development was led by a project team incorporating scientists from the African Plant Nutrition Institute (APNI), CIMMYT and local development partners in each country.
Next steps
Some studies have shown that dis-adoption of seemingly profitable technologies — such as fertilizer in sub-Saharan Africa — is quite common, especially when initial returns fall short of expectations or net utility is negative, producing a disappointment effect.
In the context of emerging digital decision-support tools for well-targeted fertilizer use recommendations, it remains unclear whether farmers’ initial input use responses and the associated economic returns affect their subsequent responses — and whether the disappointment effect can be attenuated through provision of information about uncertainty in expected returns.
Using our three-year randomized controlled trial and the associated panel dataset, researchers are now working on documenting the third-year responses of farmers to site-specific agronomic advice conditional on the second-year responses. Specifically, they seek to better document whether providing farmers with information about seasonal variability in expected investment returns can reduce possible disappointment effects associated with their initial uptake of site-specific agronomic advice and, in a way, limit dis-adoption of fertilizer.

Smallholder farmers are often torn between maize seed varieties that have multiple desirable traits. Since they cannot always have it all — there are limits on what traits breeders can integrate in any given variety — they face the dilemma of which seed to pick at the expense of an equally desirable option.
Trait preference trade-offs among maize farmers in western Kenya, published in March 2021, provides evidence of this prioritization and seeks to help breeders, seed companies and other stakeholders set priorities that account for farmers’ needs and their willingness to make preference trade-offs. The researchers evaluated responses from 1,288 male and female farmers in the mid-altitude maize growing areas of western Kenya.
The study argues that farmer-centered seed systems (including seed companies) should be guided by farmers’ priorities and reflect a greater understanding of the tradeoffs these farmers make between traits and varieties. They have two key options, according to Paswel Marenya, the study’s lead researcher and adoption and impact assessment economist at the International Maize and Wheat Improvement Center (CIMMYT). The first involves prioritizing the critical must-have traits in any one variety. The second option entails having multiple varieties that meet diverse farmers’ needs and then segmenting the seed markets.
While Marenya argues that prioritization is important for balancing commercial realities and farmers’ diverse interests, he is quick to add that “market segmentation has limits imposed by the commercial viability of each segment.”
“At every turn, from breeding to farmer varietal preferences to seed company considerations, there have to be trade-offs, as one cannot keep segmenting the market forever,” Marenya said. “At some point, you must stop and choose what traits to prioritize in your breeding or commercially viable market segments, based on the most pressing challenges already identified.”

Differences in tradeoffs among men and women
From a gender lens, the paper reveals an obvious difference in tradeoffs made by men and women. Whereas the two groups desire some similar traits in their varieties of choice, women seem to be willing to make slightly larger yield sacrifices in favor of tolerance to drought and Striga and good storability. Women also valued good storability over 90-day maturity, while men appeared to place a higher value on the closed tip, a sign of resistance to moisture infiltration which causes grain rotting.
“These results imply that unless the risks of storage or pre-harvest losses are reduced or eliminated, the value of high yielding varieties can be diminished if they are susceptible to production stresses or the grain characteristics make them susceptible to storage pests,” the study states.
The study indicates that farmers may adopt stress tolerant and high yielding varieties with somewhat low storability only if advanced grain storage technologies are available.
Until then, the suggestion to policy makers responsible for maize breeding is to use “multi-criteria evaluations” of new varieties to ensure that traits for stress tolerance and storability are given optimal weighting in variety release decisions.
Additionally, information about farmer preferences should be fed back to breeding programs in national and international institutes responsible for maize genetic improvement.
Mary Nzau enters a mock agrodealer shop set up on a field on the outskirts of Tala town in Machakos County, Kenya. On display are nine 2kg bags of hybrid maize seed. She picks one. By the look of it, her mind is made up. After a quick scan of the shelf, she has in her hand the variety that she has been purchasing for years.
Regina Mbaika Mutua is less lucky. The variety she always buys is not on display in the mock shop. As part of the experiment, the research team has removed from the shelf the variety she indicated she usually buys. The team’s goal is to observe what factors influence her seed purchase decision in the absence of the variety she was expecting to purchase.
“Although I did not find the variety I was looking for, I picked an alternative as I have seen it perform well on a neighboring farm,” Mutua says, adding that she will plant it this season alongside recycled (farm-saved) seed on her one-acre farm.
Michael Mutua passes up the popular variety he has been planting for the previous two years. He picks one that has been advertised extensively on local radio. “I have heard about it severally on radio. I would like to experiment with this new seed and see how it performs on my farm. Should I like the results, I will give it a chance in ensuing seasons,” he says.

The big adoption conundrum
The goal of the out-of-stock study is to improve an understanding of how farmers make their maize seed choices, says Pieter Rutsaert, Markets and Value Chain Specialist at the International Maize and Wheat Improvement Center (CIMMYT).
“We do this by inviting farmers to a mock agrodealer store that we set up in their villages and give them a small budget to purchase a bag of seed. However, not all farmers walk into the same store: some will find their preferred variety, others won’t. Some will have access to additional trait information or see some varieties with price promotions while others don’t.”
Rutsaert acknowledges that breeding programs and their partner seed companies have done a great job at giving farmers access to maize hybrids with priority traits such as drought tolerance and high yield. CIMMYT then works closely with local seed companies to get varieties into the hands of farmers. “We want to extend that support by providing insights to companies and public breeding programs on how to get new varieties more quickly into the hands of farmers,” he says.

The hybrid maize seed sector in Kenya is highly competitive. Amid intensifying competition, new varieties face a daunting task breaking into the market, independent of their quality. While farmers now have more options to pick from, a major challenge has been how to get them to adopt new varieties.
“Moving farmers from something they know to something they don’t is not easy. They tend to stick with what they know and have been growing for years,” Rutsaert says.
Pauline Muindi, gender research associate with CIMMYT, acted as the stand-in clerk at the mock store. She noticed that farmers tend to spend very little time in the shop when their preferred variety is available. However, this all changes in the out-of-stock situation, pushing farmers to step out of their comfort zone and explore new options.
The first step to overcoming this challenge is to entice maize farmers to try a new seed variety, even just once, Rutsaert observes. If it is a good variety, farmers will see that and then the market will work in its favor: farmers will come back to that variety in subsequent years and tell others about it.
“The good news is that many of the varieties we are currently seeing on the market have performed well — that’s why they’re popular. But there are newer varieties that are even better, especially in terms of attributes like drought tolerance. We would like to understand how farmers can be convinced to try out these newer varieties. Is it about the need for more awareness on varietal traits? Can we use price promotions? Or are there other factors?” he says.

Does seed price matter?
“With today’s climate uncertainty, it is better to stick to a variety that is adapted to such climate rather than banking on a variety one is oblivious of. The risk is not worth it,” Nzau says. She adds that she would rather buy a higher-priced seed packet she knows and trusts than a lower-priced one that she has not used in the past. Radio promotions of new or other varieties have limited sway over her decision to make the switch.
Faith Voni, another farmer, agrees. “It is better to purchase a higher-priced variety whose quality I can vouch for than risk purchasing a lower-priced one that I know little about. I do not wish to take such a risk.” Voni says she would also be more inclined to experiment with another variety that she had seen perform well on a neighbor’s farm.
Michael Mutua holds a different view. “If there is an option of an equally good but new variety that is lower-priced than the variety I prefer, my wallet decides,” he says.
Vivian Hoffmann, an economist at the International Food Policy Research Institute (IFPRI) and collaborator on the study, says price can be key for convincing consumers to try a new product. “Our previous research on maize flour choice found that a provisional 10 percent discount boosted sales tremendously,” Hoffmann says. “Of course, that only gets your foot in the door; after that, a new variety will need to win farmers over based on its merits.”
Hoffmann is interested in the extent to which drawing farmers’ attention to key varietal attributes influences their seed choice. “This information is generally already available on seed packets, but we live in a world of information overload. Promoting certain attributes through in-store signage is an approach that is widely used to help consumers make more healthier food choices. Doing the same for new seed varieties makes a lot of sense.”

The value of drought tolerance
Situated on Kenya’s eastern region, Machakos is characterized by persistent water stress. Climate change induced erratic rainfall has pushed traits that can tolerate the unfavorable weather conditions in the favorite’s corner. While other traits such as high yield and disease resistance are equally important, the seed, when planted, must first withstand the effects of droughts or water stress in some seasons and germinate. This is the most crucial step in the long journey to either a decent, bare minimum or no yield. A lot of farmers still plant recycled seed alongside hybrid varieties. But these are no match to water stress conditions, which decimate fields planted with farmer-saved seed.
“If a variety is not climate resilient, I will likely not harvest anything at all,” says Nzau. She has planted a drought-tolerant variety for ten years now. Prior to that, she had planted about three other varieties as well as recycled seed. “The only advantage with recycled seed is that given the right amount of rainfall, they mature fast — typically within two months. This provides my family with an opportunity to eat boiled or roast maize,” she notes.
However, varieties need to do more than just survive harsh weather conditions. Breeders face a daunting task of incorporating as many traits as possible to cater to the overarching and the specific interests of multiple farmers. As Murenga Mwimali, a maize breeder at the Kenya Agricultural and Livestock Research Organization (KALRO) and collaborator in this research says, innovations in breeding technologies are making breeding more efficient.
“It is better to have a diversity of product profiles as different market niches are captured within a particular agroecological zones. This is such that farmers may not just benefit from the minimum traits like drought tolerance, but also more specific traits they are looking for,” Mwimali says.
Smallholder farmers continue to play a central role in the seed development process. Capturing what happens at the point of purchase, for instance, at the agrodealer, and understanding how they purchase seed offers valuable insights on the traits that are deemed essential in the breeding process. This work contributes to CIMMYT’s focus on fast-tracking varietal turnover by turning the levers towards a demand-driven seed system.

For several decades, the International Maize and Wheat Improvement Center (CIMMYT) has worked with partners and farmers to improve maize and wheat varieties. Packed with “upgrades” such as tolerance to environmental stresses, tolerance to diseases and pests, boosted nutrient content, higher yield potential and storage capabilities, and improved efficiency in using water and fertilizers, these seeds are rolled out by CIMMYT and its partners to create new opportunities for easier and better lives for farmers.
Together with national research partners, farmers, local governments and seed companies, CIMMYT’s work in seed systems has reaped results. Its experts are eager to put this experience into further action as CGIAR embarks on the next ten years of its journey to transform food, land, and water systems in a climate crisis. And rightly so: investments in CGIAR research — mainly through their contributions to enhancing yields of staple food crops — have returned ten-fold benefits and payoffs for poor people in terms of greater food abundance, lower prices of food, reduced food insecurity and poverty and reduced geographical footprint of agriculture. A large part of this impact is the result of CIMMYT’s day to day efforts to create a better world.

Replacing old varieties, not as easy as it sounds
Slow variety turnover — that of more than ten years — makes farmers vulnerable to risks such as climate change and emerging biotic threats. On the other hand, planting improved varieties that match farmers’ needs and the geography they work in, can increase productivity gains and improve the nutritional status of smallholders and their families. This, in turn, contributes to increased household incomes. Indirectly, the benefits can reach the surrounding community by providing increased employment opportunities, wage increases and affordable access to food.
Despite its tremendous benefits, varietal turnover is no small feat.
When it comes to seeds, detailed multi-disciplinary research is behind every new variety and its deployment to farmers. Just as the production of a new snack, beverage or a car requires an in-depth study of what the customer wants, seed systems also must be demand-driven.
Socioeconomists have to work hand-in-hand with breeders and seed system specialists to understand the drivers and bottlenecks for improved varietal adoption, market needs, and gender and social inclusion in seed delivery. Bottlenecks include the lack of access by farmers — especially for resource-poor, socially-excluded ones — to reliable information about the advantages of new varieties. Even if farmers are aware of new varieties, seeds might not be available for sale where they live or they might be too expensive.
Possibly the most complex reason for slow variety turnover is risk vulnerability: some farmers simply can’t afford to take the risk of investing in something that might be good but could also disappoint. At the same time, seed companies also perceive a certain risk: they might not be interested in taking on an improved variety that trumps the seeds from older but more popular varieties they have on stock. For them, building and marketing a new brand of seeds requires significant investments.

New approaches are yielding results
Despite the complexity of the challenge, CIMMYT has been making progress, especially in Africa where slow variety turnover is creating roadblocks for increased food security and poverty alleviation.
Recent analysis of the weighted average age of CIMMYT-related improved maize varieties in 8 countries across eastern and southern Africa reveals that the overall weighted average age has decreased from 14.6 years in 2013 to 10.2 years in 2020. The remarkable progress in accelerating the rate of variety turnover and deploying the improved genetics — with climate resilience, nutritional-enhancement and grain yield — are benefiting more than eight million smallholders in Africa.
In Ethiopia, CIMMYT, EIAR and ICARDA’s work led to the adoption of improved rust-resistant varieties, corresponding productivity gains and economic benefits that, besides the urgent need to fight against the damaging rust epidemic, depended on a combination of enabling factors: pre-release seed multiplication, pro-active policies and rust awareness campaigns. The estimated income gain that farmers enjoyed due to adopting post-2010 varieties in 2016/2017 reached $48 million. For the country itself, the adoption of these varieties could save $65 million that otherwise would be spent on wheat imports.
Bill Gates echoes this in Chapter 9 of his new climate book, How to Avoid a Climate Disaster, as he describes CIMMYT and IITA’s drought-tolerant maize work: “[…] experts at CGIAR developed dozens of new maize varieties that could withstand drought conditions, each adapted to grow in specific regions of Africa. At first, many smallholder farmers were afraid to try new crop varieties. Understandably so. If you’re eking out a living, you won’t be eager to take a risk on seeds you’ve never planted before, because if they die, you have nothing to fall back on. But as experts worked with local farmers and seed dealers to explain the benefits of these new varieties, more and more people adopted them.”

Holistic action needed if we are to reach farmers with genetic innovations
Now more than ever, with increased frequency and intensification of erratic weather events on top of the complications of the COVID-19 pandemic, successful seed systems require the right investments, partnerships, efforts across disciplines, and enabling policies.
Varietal release and dissemination systems rely greatly on appropriate government policies and adoption of progressive seed laws and regulations. CGIAR’s commitment to farmers and the success of national seed systems is described in the recently launched 10-year strategy: “CGIAR will support effective seed systems by helping national governments and private sector companies and regulators build their capacities to play their roles successfully. New initiatives will be jointly designed along the seed distribution chain, including for regional seed registration, import and export procedures, efficient in-country trialing, registration and release of new varieties, and seed quality promotion through fit-for-purpose certification.”
In line with CGIAR’s ambitious goals, to provide farmers with a better service, small- and medium-size seed companies need to also be strengthened to become more market-oriented and dynamic. According to SPIA, helping local private seed dealers learn about new technology increases farm-level adoption by over 50% compared to the more commonly used approach, where public sector agricultural extension agents provide information about new seed to selected contact farmers.
CIMMYT socioeconomics and market experts are putting this in practice through working with agrodealers to develop retail strategies, such as targeted marketing materials, provision of in-store seed decision support and price incentives, to help both female and male farmers get the inputs that work best.
Within the new CGIAR, CIMMYT scientists will continue to work with partners to strongly improve the performance of wheat and maize in smallholder farmers’ fields. Concerted efforts from all actors conforming the entire seed system are essential to achieve our vision: to transform food systems for affordable, sufficient and healthy diets produced within planetary boundaries. Wheat and maize seed systems will form the basis to fulfill that vision and provide a tried and tested roadmap for other crops, including legumes, vegetables and fruits. Together, we can keep a finger on the pulse of farmers’ needs and build healthy diets for a better tomorrow from the ground up.
