India has conferred posthumously upon Sanjaya Rajaram, 2014 World Food Prize laureate and former wheat breeder and Director of the Wheat Program at the International Maize and Wheat Improvement Center (CIMMYT), its prestigious 2022 Padma Bhushan Award in “Science and Engineering” in recognition of “distinguished service of high order.”
Among the most successful crop breeders in history, Rajaram, who passed away in 2021, personally oversaw the development of nearly 500 high-yielding and disease-resistant wheat varieties that were grown on at least 58 million hectares in over 50 countries, increasing global wheat production by more than 200 million tons and especially benefiting hundreds of millions of the resource-poor whose diets and livelihoods depend on this critical crop. In India and the neighboring South Asian nations of Bangladesh, Nepal, and Pakistan, inhabitants consume more than 120 million tons of wheat and wheat-based foods each year.
“Dr. Rajaram was a true titan of wheat breeding and an inspiration for young researchers, training and mentoring more than 700 scientists from developing countries worldwide,” said Bram Govaerts, CIMMYT director general. “He was also a complete gentleman, comporting himself with modesty and grace despite his many honors and accomplishments; his first priority was helping and crediting others. Rajaram is an example today for all of us to keep working with the final stakeholder — the farmer — in mind.”
The rise from rural beginnings
Born on a small farm in District Varanasi, Uttar Pradesh, India, in 1943, Rajaram studied genetics and plant breeding at the Indian Agricultural Research Institute in New Delhi. After receiving his Ph.D. from the University of Sydney, he joined CIMMYT in 1969, working as a wheat breeder alongside Nobel Prize Laureate and CIMMYT scientist Norman Borlaug in Mexico. Recognizing his talent and initiative, Borlaug appointed Rajaram as head of CIMMYT’s wheat breeding program at just 29 years of age.
The Padma Bhushan Award was announced by President Ram Nath Kovind of India on the country’s Republic Day, January 26. In 2015, Rajaram received the Pravasi Bharatiya Samman award, the highest honor conferred on Indians overseas. In 2001 he accepted the Padma Shri award from the government of India and, in 1998, the Friendship Award from the government of China.

Though a plant breeder and scientist by profession, Rajaram used the platform of his 2014 World Food Prize to promote an expansive, integrated vision for agricultural development. “If we want to make a change, research won’t do it alone; we need to work directly with farmers and to train young agronomists, ensuring they have a broad vision to address the problems in farmers’ fields,” Rajaram said at a news conference in Mexico City in 2014.
Rajaram also served as Director of the Integrated Gene Management Program at the International Center for Agricultural Research in the Dry Areas (ICARDA) before formally retiring in 2008. In his retirement, he continued as a special scientific advisor to CIMMYT and ICARDA.
Longstanding partners pushing forward for farmers
“India’s agricultural research community is proud of the distinguished achievements of Dr. Rajaram,” said Trilochan Mohapatra, Director General of the Indian Council of Agricultural Research (ICAR) and Secretary of the Department of Agricultural Research and Education (DARE), of India’s Ministry of Agriculture and Farmers’ Welfare. “ICAR greatly appreciates its valuable collaborations with CIMMYT to help farmers grow better crops and conserve resources under increasingly challenging conditions.”
The partnership of India with CIMMYT harks back to the 1960s-70s, when Indian farmers tripled national wheat yields in a few years by growing Borlaug’s high-yield wheat varieties and adopting improved farming practices.
In 2011, India and CIMMYT jointly launched the Borlaug Institute for South Asia (BISA) to improve cropping systems and food security, helping farmers to confront climate change and natural resource scarcities, among other challenges.
S. Ayyappan, former ICAR Director General who signed the joint declaration of intent for BISA’s establishment in India, has been honored with the 2022 Padma Shri Award.
CIMMYT is a non-profit international agricultural research and training organization focusing on two of the world’s most important cereal grains, maize and wheat, and related cropping systems and livelihoods. Wheat varieties derived from CIMMYT and ICARDA research cover more than 100 million hectares — nearly two-thirds of the area sown to improved wheat worldwide — and bring benefits in added grain worth as much as $3.8 billion each year.
Several recent studies document the long-term health and economic benefits from the “Green Revolution” — the widespread adoption of high-yielding staple crop varieties during the last half of the 20th century — and argue for continued investment in the development and use of such varieties.
“Our estimates provide compelling evidence that the health benefits of broad-based increases in agricultural productivity should not be overlooked,” the authors state. “From a policy perspective, government subsidies for inputs leading to a green revolution as well as investments in extension and R&D programs seem to be important.”

The COVID-19 pandemic exposed the fragility of the global food system and the need to transform it, increasing its environmental and economic resilience to withstand future threats, and underpinning healthier diets. The studies suggest that improved versions of cereal crops such as rice, wheat, and maize can play a key role.
“Our work speaks to the importance of supporting innovation and technology adoption in agriculture as a means of fostering economic development, improved health, and poverty reduction, said author Jan von der Goltz. “It also suggests that it is reasonable to view with some alarm the steady decline in funding for cereal crop improvement over the last few decades in sub-Saharan Africa, the continent with least diffusion of modern varieties.”
Likewise, a study co-authored by Prashant Bharadwaj of the University of California, San Diego, concluded that farmer adoption of high-yielding crop varieties (HYVs) in India reduced infant mortality dramatically across the country. Between 1960 and 2000, infant deaths dropped from 163.8 to 66.6 per 1,000 live births, and this occurred during the decades of India’s wheat productivity leap from 0.86 to 2.79 tons per hectare, as a result of HYV adoption and improved farming practices.
“What both of these papers do is to carefully establish a causal estimate of how HYVs affect infant mortality, by only comparing children born in the same location at different points in time, when HYV use was different, and by checking that mortality before arrival of HYVs was trending similarly in places that would receive different amount of HYVs,” Bharadwaj said.
“In the absence of a randomized control trial, these econometric techniques produce the best causal estimate of a phenomenon as important as the spread of HYVs during and after the Green Revolution,” he added. These thoughts were echoed by University of California San Diego professor Gordon McCord, a co-author of the global study.
Recent studies indicate that the Green Revolution also had long-term economic impacts, which also affected health outcomes.
In a 2021 update to the 2018 paper “Two Blades of Grass: The Impact of the Green Revolution,” Douglas Gollin, Professor of Development Economics at Oxford University and co-authors found that, in 90 countries where high-yielding varieties were adopted between 1965 and 2010, food crop yields increased by 44% and that, had this adoption not occurred, GDP per capita in the developing world could be half of what it is today.
Even a 10-year delay of the Green Revolution would, in 2010, have cost 17% of GDP per capita in the developing world, with a cumulative GDP loss of $83 trillion, equivalent to one year of current global GDP.
These GDP and health impacts were boosted by a related reduction in population growth. By observing causal inference at country, regional and developing world levels, and using a novel long-term impact assessment method, the study authors detected a trend: as living standards improved for rural families, they generally wanted to invest more in their children and have fewer.
“Our estimates suggest that the world would have contained more than 200 million additional people in 2010, if the onset of the Green Revolution had been delayed for ten years,” Gollin and his co-authors stated. This lower population growth seems to have increased the relative size of the working age population, which furthered GDP growth.

A long-term investment in system transformation
It takes time from the point of an intervention to when broad health impacts can be observed in the population, the authors note. For example, although the development of modern high-yielding varieties began in the 1950s and 60s, the rate of adoption did not speed up until the 1980s, 1990s, and even into the 2000s, with evidence from sub-Saharan Africa showing that variety adoption has increased by as much in the 2000s as in the four preceding decades.
In addition, any nutrition and food security strategy which aims to reach the second Sustainable Development Goal of feeding 9 billion by 2050 must incorporate wider system transformation solutions, such as zero-emissions agriculture, affordable, diverse diets and increased land conservation.
As Gollin explained, “The Green Revolution taught us that we need to approach productivity increases, especially in staple crop yields, differently. The challenge now is more complex: we need to get the same productivity increases, with fewer inputs and resources, more environmental awareness, and in larger quantities for more people.”
In part, this means increasing productivity on existing agricultural land with positive environmental and social impacts, according to Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT).
“Breeding and sharing more productive, hardy crop varieties is as important as ever,” Govaerts said, “but also engaging farmers — in our case, smallholders — in shared research and innovation efforts to bridge yield gaps, build climate-resilient farming systems, and open access to better nutrition and market opportunities.”

A five-year partnership being launched by the Innovative Genomics Institute (IGI)—a non-profit founded by Nobel Laureate Jennifer Doudna—and CGIAR, the world’s largest publicly-funded agricultural research partnership, will harness the power of science to help millions of people overcome poverty, hunger and malnutrition.
One in four people globally, and rising, are unable to afford a healthy diet. COVID-19 has exacerbated this trend by disrupting food production and distribution, driving up by 20 percent the number of people threatened by hunger in 2020. The pandemic is unfolding amidst an environmental and climate crisis which is undermining food production and our ability to nourish the world.
But global consensus is building for urgent action. At the COP26 meetings in November, 45 nations committed to shifting to more sustainable ways of farming and accelerate the deployment of green innovations. Similarly, in late September, many government representatives at the United Nations Food Systems Summit committed to accelerating the transformation of how we grow, transport, process, and consume food. Recognizing the centrality of science and innovation for driving that transformation, United Nations Secretary-General António Guterres called on the world to scale public and private investment in research for food.
According to Barbara Wells, Global Director for Genetic Innovation at CGIAR: “World-class science is vital for facilitating farmer adaptation and mitigating our food system’s contribution to climate change. Plant-breeding innovations can help ramp up food production while making farms more climate resilient, profitable and environmentally friendly”.
“Technologies such as gene editing, which enable scientists to make targeted changes to a crop’s DNA, can accelerate the development of more disease-resistant, water-efficient varieties that can improve food production and nutrition in areas that are especially vulnerable to climate change,” Dr. Wells explained.
CGIAR has produced and promoted innovations that are boosting the sustainable production of nutritious food in Africa, Asia and Latin America. Over the past five decades, CGIAR scientists and national partners have developed and disseminated robust and highly productive crop varieties and livestock breeds tailored to the needs of local men and women. Those innovations have helped hundreds of millions of people across the Global South overcome hunger and poverty.
The IGI is a collaboration of the University of California, Berkeley and the University of California, San Francisco with a mission to develop revolutionary genome-editing tools that enable affordable and accessible solutions in human health, climate, and agriculture. The IGI’s Climate & Sustainable Agriculture program focuses on developing crops that are resistant to pests and diseases, resilient to a changing climate, and less dependent on farmer inputs. Whereas the IGI is a pioneer in applied genomic research, CGIAR focuses on translating discoveries into improved crop varieties and cropping systems. This partnership provides an accelerated pipeline from upstream innovation to real-world impact.
“The IGI is testing technologies with great potential to benefit people in the countries where CGIAR is active, such as a way of removing the cyanide found in cassava—a staple upon which nearly a billion people depend—and fighting diseases in economically important crops like wheat, rice and bananas,” said Brian Staskawicz, the IGI Director of Sustainable Agriculture.
“The IGI is also pioneering new ways to reduce methane emissions from rice farming, which accounts for 2.5 percent of humanity’s contribution to global warming, by using genomic approaches to reduce methane production by soil microbes,” he added.
“By partnering with CGIAR, the IGI can ensure that the products of its research will benefit farmers and consumers in some of the world’s poorest countries, where CGIAR has been working for 50 years and has extensive partner networks,” said Dr. Melinda Kliegman, Director of Public Impact at the IGI. “Together we can accelerate the development and delivery of more climate-resilient, productive and nutritious crops for resource-poor farmers and consumers.”
Over the next five years, the IGI and CGIAR will use the latest breakthroughs in genomic science to enhance the resilience and productivity of farmers in low- and middle-income countries and improve the wellbeing and livelihoods of women and men in some of the world’s poorest communities.

Over 70% of rural women in India are engaged in agriculture. Women carry out a large portion of farm work, as cultivators and agricultural laborers, but in most cases they are not even counted and recognized as farmers. Millions of Indian rural women also carry the burden of domestic work, a job that is undervalued and unrecognized economically.
On the International Day of Rural Women, October 15, the focus is on their contributions to growing food and feeding families. The often invisible hands of rural women play a pivotal role in food security and sustaining rural communities.
Today, we have a glimpse at the daily life of farmer Anita Naik.
She hails from the village of Badbil, in the Mayurbhanj district of India’s Odisha state, surrounded by small hills and the lush greenery of Simlipal National Park.
Naik belongs to a tribal community that has long lived off the land, through farming and livestock rearing. Smallholder farmers like her grow rice, maize and vegetables in traditional ways — intensive labor and limited yield — to ensure food for their families.
Married at a young age, Naik has a son and a daughter. Her husband and her son are daily-wage laborers, but the uncertainty around their jobs and her husband’s chronic ill health means that she is mostly responsible for her family’s wellbeing. At 41, Naik’s age and her stoic expression belie her lifelong experience of hard work.
The small hours
Naik’s day begins just before dawn, a little past 4 a.m., with household chores. After letting out the livestock animals — goats, cows, chicken and sheep — for the day, she sweeps the house’s, the courtyard and the animal shed. She then lights the wood stove to prepare tea for herself and her family, who are slowly waking up to the sound of the crowing rooster. Helped by her young daughter, Naik feeds the animals and then washes the dirty dishes from the previous evening. Around 6:30 or 7 a.m., she starts preparing other meals.
During the lean months — the period between planting and harvesting — when farm work is not pressing, Naik works as a daily-wage worker at a fly ash brick factory nearby. She says the extra income helps her cover costs during emergencies. “[I find it] difficult to stay idle if I am not working on the farm,” she says. However, COVID-19 restrictions have affected this source of income for the family.
Once her morning chores are over, Naik works on her small plot of land next to her house. She cultivates maize and grows vegetables, primarily for household consumption.
Naik started growing maize only after joining a self-help group in 2014, which helped her and other women cultivate hybrid maize for commercial production on leased land. They were supported by the International Maize and Wheat Improvement Center (CIMMYT) through the Cereal Systems Initiative for South Asia (CSISA) maize intensification program.
Every year from June to October, Naik also work on this five-acre leased farmland, along with the other group members. She is involved from planting to harvest — and even in marketing.
“There are eleven women members in our self-help group, Biswa Jay Maa Tarini. Thanks to training, awareness and handholding by CSISA and partners, an illiterate like me is currently the president of our group,” said an emotional Anita Naik.

Not quite done yet
A little further away from her house, Naik has a small field where she grows rice with the help of her husband and son. After checking in on her maize crop on the leased land, Naik works in her paddy the rest of the day. She tends to her land diligently, intent on removing the weeds that keep springing up again and again in the monsoon season.
“It is back-breaking work, but I have to do it myself as I cannot afford to employ a laborer,” Naik laments.
Naik finally takes a break around 1 p.m. for lunch. Some days, particularly in the summer when exhaustion takes over, she takes a short nap before getting back to removing weeds in the rice fields.
She finally heads home around 4 p.m. At home, she first takes the animals back into their shed.
Around 6 p.m., she starts preparing for dinner. After dinner, she clears the kitchen and the woodstove before calling it a night and going to bed around 8 or 9 p.m.
“The day is short and so much still needs to be done at home and in the field,” Naik says after toiling from early morning until evening.
Tomorrow is a new day, but chores at home and the work in the fields continue for Naik and farmers like her.

Paradigm change
Traditionally farmers in and around Naik’s village cultivated paddy in their uplands for personal consumption only, leaving the land fallow for the rest of the year. Growing rice is quite taxing as paddy is a labor-intensive crop at sowing, irrigating, weeding and harvesting. With limited resources, limited knowledge and lack of appropriate machinery, yields can vary.
To make maximum use of the land all year through and move beyond personal consumption and towards commercial production, CIMMYT facilitated the adoption of maize cultivation. This turned out to be a gamechanger, transforming the livelihoods of women in the region and often making them the main breadwinner in their families.
In early 2012, through the CSISA project, CIMMYT began its sustainable intensification program in some parts of Odisha’s plateau region. During the initial phase, maize stood out as an alternative crop with a high level of acceptance, particularly among women farmers.
Soon, CIMMYT and its partners started working in four districts — Bolangir, Keonjhar, Mayurbhanj and Nuapada — to help catalyze the adoption of maize production in the region. Farmers shifted from paddy to maize in uplands. At present, maize cultivation has been adopted by 7,600 farmers in these four districts, 28% of which are women.
CIMMYT, in partnership with state, private and civil society actors, facilitated the creation of maize producers’ groups and women self-help groups. Getting together, farmers can standardize grain quality control, aggregate production and sell their produce commercially to poultry feed mills.
This intervention in a predominantly tribal region significantly impacted the socioeconomic conditions of women involved in this project. Today, women like Anita Naik have established themselves as successful maize farmers and entrepreneurs.
In a small workshop in Ethiopia’s Oromia region, mechanic Beyene Chufamo and his technician work on tractor repairs surrounded by engines and spare machinery parts.
Established in Meki in 2019, Beyene’s workshop provides maintenance, repair and overhaul services for two-wheel tractors and their accessories, and it acts as a point of sale for spare parts and implements such as planters, threshers and water pumps. Beyene also works as a tractor operation instructor, providing trainings on driving, planter calibration and how to use threshers and shellers.
The city already had a well-established mechanics and spare parts industry based around four-wheel tractors and combine harvester hire services, as well as motorcycle and tricycle transportation services. But now, as market demand for two-wheel tractor hire services rises among smallholder farming communities and entrepreneurial youth race to become local service providers, business is booming.

Building a business
Beyene’s business has benefitted from support from the International Maize and Wheat Improvement Center (CIMMYT) and the German development agency GIZ since its formation. Beyene was initially trained as a mechanic through the Innovative Financing for Sustainable Mechanization in Ethiopia (IFFSMIE) project, which promotes small-scale mechanization in the area through demand creation, innovative financing mechanisms and the development of private sector-driven business. He went on to receive additional technical and business skills development training to enable him to run his own enterprise.
His ongoing association with the project and its new leasing scheme has helped Beyene establish connections with local service providers, while also improving his own skills portfolio. Currently, he helps maintain the smooth operation of machinery and equipment at CIMMYT project sites in Amhara, Oromia and Tigray. This involves everything from training other local mechanics and troubleshooting for service providers, to facilitating the delivery of aftersales services in project areas.
In addition to this, Beyene receives orders for maintenance, repair and overhaul services for two-wheel tractors and implements. He sources replacement parts himself, though the cost of purchase is covered by his clients. In some cases — and depending on the distance travelled — CIMMYT covers the transport and accommodation costs while Beyene services equipment from service providers and sources equipment from local distributors. When individual parts are not readily available, he often purchases whole two-wheel tractors from the Metals and Engineering Corporation (METEC) and breaks them down into individual parts.

The way forward for sustainable mechanization
“Mechanization take-off relies heavily on skilled staff and appropriate infrastructure to perform machinery diagnostics, repair and maintenance,” said Rabe Yahaya, a CIMMYT agricultural mechanization expert based in Ethiopia.
“Agricultural machinery should be available and functional any time a famer wants to use it — and a workshop can support this. Beyene’s work in Meki reflects the way forward for sustainable mechanization success in Ethiopia.”
Creating an agricultural machinery workshop from scratch was a challenging task, Rabe explained, but support and guidance from partners like CIMMYT and GIZ helped to make it happen. “Also, Beyene’s commitment and flexibility to travel to CIMMYT project sites anywhere and at any time — even on bad roads in difficult weather conditions — really helped him achieve his goal.”

Beyene is excited about how quickly the local two-wheel tractor market has grown in the past few years. He currently has 91 service providers as regular clients at CIMMYT project sites — up from just 19 in 2016.
Trends show that — with support from local microfinance schemes and the removal of domestic taxes on imported machinery — aftersales services will continue to evolve, and the number of service providers will rise alongside increased market demand for mechanization services, both at farm level and beyond.
With this in mind, Beyene aims to remain competitive by diversifying the services offered at his workshop and expanding his business beyond CIMMYT project sites. As a starting point he plans to hire more staff, altering his organizational structure so that each mechanic or technician is dedicated to working with a specific type of machinery. Longer term, he hopes to transform his workshop into one that can also service four-wheel tractors and combine harvesters, and establish a mobile dispatch service team that can reach more locations in rural Ethiopia.
For now, however, he simply remains grateful for CIMMYT’s support and investment in his business. “I am happy that I have been able to secure an income for myself, my family and my staff through this workshop, which has changed our lives in such a positive way.”

It is a laborious and time-consuming process: chopping plant matter by hand to feed to livestock. In Cox’s Bazar district, in eastern Bangladesh, it is common practice. A mechanized fodder chopper can do the job more quickly and efficiently — yet this simple but effective machine has not seen much use in the region.
To address this, a collaboration between the International Maize and Wheat Improvement Center (CIMMYT) and aid organizations in the region is creating networks between farmers, agriculture service providers and the businesses that make and distribute the machines.
The Cox’s Bazar region is host to around 900,000 Rohingya refugees who were displaced from Myanmar. The influx of refugees has put a strain on resources in the region. This collaborative effort took place near the camps, in an effort to support capacity and economic development in the host communities nearby.
Though this collaboration has only been around for a few months, it has already seen early success, and received an award from the United States Agency for International Development (USAID). The award recognized the organizations’ “outstanding collaboration that contributed to increased and efficient livestock production through mechanization in the host communities impacted by the influx of Rohingya refugees.”
Mechanization and livestock collaboration
The project — funded by USAID — is a partnership between two existing efforts.
The first is Cereal Systems Initiative for South Asia – Mechanization Extension Activity (CSISA-MEA), which aims to boost the country’s private agricultural machinery industry while supporting local farmers. This initiative supports the mechanization of agriculture in Bangladesh, through increased capacity of the private sector to develop, manufacture and market innovative new technologies. CSISA-MEA is implemented by the International Maize and Wheat Improvement center (CIMMYT) in partnership with iDE and Georgia Institute of Technology.
The second is the Livestock Production for Improved Nutrition (LPIN) Activity, which works to improve nutrition and income generation among rural households in the region.
“We made a great collaboration with LPIN,” said Jotirmoy Mazumdar, an agriculturalist working with CSISA-MEA. “We’re very happy that our initiative helped us achieve this award. In this short time period, a new market opportunity was created.”
Nonstop chop
There are numerous benefits to using fodder choppers, according to Muhammad Nurul Amin Siddiquee, chief of party of LPIN. For one, having access to the choppers can save farmers around $7 (600 Bangladeshi taka) in labor costs per day, and reduce the amount of feed wasted by 10–15%. On average, a farmer can hand-chop 500 kg of forage or fodder each day, while the machines can process around 1,000 kg of the material per hour.
According to Siddiquee, giving chopped feed to livestock improves their productivity. One farmer’s herd of 17 crossbreed cows produced 115 liters of milk per day — he expects this to increase to 130 liters per day after feeding them fodder produced with a mechanized chopper.
“He can now save labor costs and four hours of his time per day by using the fodder chopping solutions,” he said, adding that the collaborative effort is “fostering increased livestock productivity and [farmer] incomes.”
However, Cox’s Bazar is far away from the center of Bangladesh, where most of these machines are produced. For example, there are more than 30 small engineering workshops in the more centrally located Khulna Division and they have cumulatively made 7,470 choppers.
“In Cox’s Bazar, it was almost impossible for those livestock farmers to get to know the chopper machines, and actually get access to them,” said Khaled Khan, team lead with iDE, who also aided in private-sector engagement.
So, the collaboration between CSISA-MEA and LPIN began connecting farmers and agriculture service providers with these fodder chopper producers and distributors. Moreover, it worked to increase knowledge of how to operate the machines among the farmers.
“Fodder choppers are an entirely new technology in Cox’s Bazar,” said Zakaria Hasan, CSISA team lead in the district.
Though it is still early days, the partnership has been met with a warm reception. Farmers and agriculture service providers cumulatively purchased 12 of the choppers within two weeks — each machine can support its owner and five other farmers — and three dealers are now selling the machines to meet farmer demand. In the region, 60 dairy farms are now purchasing chopped fodder for their livestock.
According to Khan, engaging the private sector in this project was essential. He explained that increasing the connectivity between the buyers and the sellers will help make the market larger and more stable.
“We found the perfect opportunity of supply and demand because their partners are demanding our partners’ service. The role of the private sector was the most important for the sustainability of this marriage of demand and supply,” Khan said.
“We want to establish a linkage between these two private entities. Our project’s job is to facilitate that, so that even after the project is over this networking continues in the future.”

As the world turns its attention to the policy-shaping discussions during this week’s Pre-Summit of the UN Food System Summit, the need for science and innovation to advance the transformation of food, land and water systems is clear.
The International Maize and Wheat Improvement Center (CIMMYT), with its 50-year track record of impact, success and high return on investment, is essential to these efforts.
Our new institutional brochure, Maize and wheat science to sustainably feed the world, links CIMMYT’s mission, vision and excellence in science to the urgent needs of a world where an estimated tenth of the global population — up to 811 million people — are undernourished.
CIMMYT is also a crucial wellspring of response capacity to CGIAR — the largest global, publicly funded research organization scaling solutions for food, land and water system challenges.
Maize and wheat science to sustainably feed the world explains why we do what we do in light of these challenges.
CIMMYT leads maize and wheat research for food systems that deliver affordable, sufficient, and healthy diets produced within planetary boundaries.
Our research is focused on smallholder farmers in low- and middle-income countries and on improving the livelihoods of people who live on less than $2 a day.
CIMMYT science reaches them through innovation hubs, appropriate technologies, sustainable sourcing, and helps to address their needs and challenges through public policy guidance.
Applying high-quality science and strong partnerships, CIMMYT works for a world with healthier and more prosperous people, free from global food crises and with more resilient agri-food systems.
We began 2020 with grim news of the COVID-19 pandemic spreading from country to country, wreaking havoc on national economies, causing countless personal tragedies, and putting additional pressure on the livelihoods of the poor and hungry.
The global crisis exposed the enormous vulnerability of our food system.
If we have learned anything from the past year, it is that we need to urgently invest in science for renewed food systems that deliver affordable, sufficient, and healthy diets produced within planetary boundaries.
During this time, the dedication and resilience of the CIMMYT community allowed us to continue making important advances toward that vision.
We hope you enjoy reading our stories and will join us in actively working towards resilience, renewal and transition in our agri-food systems, to ensure that they are strong in the face of current and future crises.
In the plains area of Nepal’s Terai and in larger valleys in the hills, many parts of rice and wheat grain production process are nearly 100% mechanized. The second half of wheat and rice harvesting –– threshing and cleaning –– was mechanized as early as the 1960s. By the mid-1990s nearly 100% of wheat in the Terai was being threshed mostly by stand-alone threshers that were powered by 5-8 horsepower (HP) diesel pumpset engines.
Rice threshing began first in the far eastern Terai in early 2000s with similarly small-sized rice threshers with pumpset engines. However, by the 2010s as 4WTs became ubiquitous in the Terai, the larger horsepower tractor power take-off (PTO) driven wheat and rice threshers became prominent
However, one of the main parts of the production process, the field harvesting of grain, is still not yet fully mechanized even though it is has one of the largest labor requirements. Grain harvesting machinery entered Nepal from India in the late 1990s with the introduction of large 90+ horsepower self-propelled combines in central Terai (Parasi, Rupandehi and Kapilvastu Districts), mainly for wheat. Machines for rice harvesting were introduced in the Western Terai by the 2010s.
In the last decade, the types and numbers of powered or mechanized harvest technologies in Nepal has greatly increased in size. With advent of many new machines from China and elsewhere, the market for grain harvest machinery has become very dynamic. Nevertheless, various bottlenecks limit access and usage far below demand.
A new study by researchers from the Cereal Systems Initiative for South Asia (CSISA), a project led by the International Maize and Wheat Improvement Center (CIMMYT), provides the results of a study on the value chains of rice, wheat and maize harvesting equipment that are used in Nepal by farmers and service providers. It documents the movement of the various new technologies into the value chain, characterizing the whole harvesting machinery market.
The study also provides a detailed value chain map of the various reaper-harvesters, threshers, shellers and combine harvesters that are now widely available for sale in Nepal with the overall goal of providing recommendations for policy makers and development agencies to promote greater access to and usage of such machinery.
A multi-disciplinary team of agricultural researchers and development practitioners is proposing a new approach to tackle the shortcomings of global food production systems that degrade the environment, greatly contribute to climate change and fail to deliver healthy diets for a growing population.
The new methodology developed by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) aims to transform national food systems by achieving consensus between multiple stakeholders and building on successful participatory agricultural research experiences.
According to a peer-reviewed paper published today in the journal PLOS ONE, the Integrated Agri-food System Initiative (IASI) “is designed to generate strategies, actions, and quantitative, [Sustainable Development Goals] SDGs-aligned targets that have [a significant] likelihood of supportive public and private investment”.
The IASI methodology is based on successful integrated development projects implemented by CIMMYT in Mexico and Colombia, the latter in partnership with the Alliance Bioversity-CIAT, which engaged multiple public, private and civil sector collaborators in local maize systems enhancement. These initiatives took advantage of sociopolitical “windows of opportunity” that helped build multiple stakeholder consensus around health, nutrition, food security and development aspirations in both countries.
“CIMMYT’s integrated development approach to maize systems transformation in Mexico and Colombia laid the foundations of the IASI methodology by overcoming government transitions, annual budget constraints and win-or-lose rivalry between stakeholders in favor of equity, profitability, resilience and sustainability,” said Bram Govaerts, chief operating officer and Integrated Development Program director at CIMMYT.
Ultimately, the IASI methodology offers public officials and development practitioners the possibility to transform food systems by scaling out innovative farming practices and technologies that lead to sustainably managed natural resources and improved nutrition and food security.
The main steps to implement the IASI methodology are:
Diverse experts examine the current status and the business-as-usual scenario based on analysis of the socioeconomic, political, and sectoral context and model-based projections;
Stakeholders determine a preferred future scenario based on assessment of national implications, and define drivers of change toward a desired scenario;
Defined criteria are applied to stakeholder and expert inputs to validate drivers of change and to identify strategies and actions — for example, public policies, value chain and market interventions, and biotechnology applications — that can steer toward the preferred future scenario, which are then reviewed and prioritized by high-level decision makers;
Stakeholders agree on measurable targets and tangible, time-bound actions toward the preferred future scenario;
Stakeholders build shared commitment to a tactical implementation plan among traditional, non-traditional, and new partners;
Ongoing stakeholder engagement is organized around an online dashboard that tracks actions and progress toward targets and supports course correction and coordinated investment.
Following these steps, the authors of the IASI methodology propose to build a “global food systems transformation network” to co-design and co-implement agricultural development projects that bring together multiple partners and donors for global agricultural systems transformation.
As the approach is refined and further applications are built, it is expected that this network will harness efforts to initiate a new field of research and global practice on “integrated methodologies for food system transformation and innovation” — analogous to the fields of business administration and organizational development.
IASI serves as the backbone of new CGIAR Regional Integrated Initiatives, which draw on capacities from regional international agricultural research centers and programs to deliver global agri-food system transformation.
The state of Odisha, in the east of India, ranks sixth in rice production in the country. Agriculture in Odisha’s tribal-dominated plateau region, however, is characterized by depleted soils along with low and variable rice yields. During the monsoon season, more than 60,000 hectares of land are left fallow, due to lack of knowledge and to farmers’ low risk tolerance.
In districts like Mayurbhanj, over 50% of the population belongs to tribal groups. Women there are mostly engaged in traditional roles: being at home looking after family, farm and livestock while their men are away as migrant laborers or with menial jobs. Women working on farming used to be considered daily wage laborers, as if they were only supporting their husband or family who were officially the farmers.
The last few years, with the introduction of maize cultivation and its promotion predominantly for women farmers, a significant change in the perception of women’s role is unfolding in the region.
In 2013, the International Maize and Wheat Improvement Center (CIMMYT) began working in the plateau region through the Cereal Systems Initiative for South Asia (CSISA), improving farming systems for higher yields and providing sustainable livelihood options for tribal farmers. Since then, farmers in the region have achieved considerable production of maize in the monsoon season — and women have particularly led this transformation.
Farmers from this region — 28% of which were women — converted 5,400 hectares of fallow lands into successful maize cultivation areas. Not only has this new opportunity helped improve family income, but also women’s identity as resilient and enterprising farmers.
This impact was possible through the applied research efforts of the CSISA project along with partners like Odisha’s State Department of Agriculture, the Odisha Rural Development and Marketing Society (ORMAS), the Integrated Tribal Development Agency (ITDA) and two federations of women’s self-help groups supported by PRADAN.
On International Women’s Day, we share the story of these successful farmers who have made maize cultivation a part of their livelihoods and a tool for socioeconomic development.
Transforming fallow lands into golden maize fields
Women working in the fields used to be considered daily wage laborers, but today they are acknowledged as enterprising farmers who transformed fallow lands into golden maize fields.
In the season 2019/2020 alone, in all four districts where CSISA is actively engaged — Bolangir, Keonjhar, Mayurbhanj and Nuapada — improved maize cultivation was adopted by 7,600 farmers — 28% of which were women — in 5,400 hectares of fallow land, resulting in considerable production of quality maize in the region. Since many of the women in the districts are smallholder farmers or without agriculture land, farming also happens on leased land through self-help groups.
Learning and implementing best maize cultivation practices
CSISA supports the farmers all the way from sowing to crop harvesting, ensuring the produce is shiny and golden. Through self-help groups, farmers have access to fertilizers and machines to weed and earth-up their fields. Researchers have introduced seed cum fertilizer drills for maize sowing, which make fertilizer placement more uniform and crop establishment easier, saving time and helping these women manage both household responsibilities and the farm.
Quality knowledge for quality grain
To strengthen the capacity of farmers, the project team trains them continuously on grain quality parameters like moisture level, foreign matters, infestation rate. Most of the participants are farmers from women collectives and self-help groups. They have gradually advanced in their knowledge journey, going from general awareness to subject-specific training.
Marketing gurus
Even though many large poultry feed mills operate in Odisha, most of their maize comes from outside the state. Women self-help groups are bridging that gap. In collaboration with the State Department of Agriculture and Farmers’ Empowerment, the CSISA project has cultivated a network of market actors including producers, providers of agricultural inputs and development partners. Market access to these value chains will help women, all the way from planting to produce marketing.
Extending the collaboration, in the four districts of Odisha and beyond
A considerable increase in maize production has improved incomes for families across the regions, as well as their food security. It has also created opportunities for women to raise their social and economic standing.
There are opportunities for CSISA and its partners to continue collaborating in the project region and beyond. CIMMYT has worked with Odisha’s State Department of Agriculture, the Odisha Rural Development and Marketing Society (ORMAS), the Integrated Tribal Development Agency (ITDA), women’s self-help groups, farmers’ producer groups, private seed companies and many other collectives.
Weathering the crisis
Women have shouldered the responsibility and led their families out of the COVID-19 crisis. When men were left jobless and stranded as migrant workers during lockdown, many women associated with the CSISA project began generating income by selling green corn. This small income helped ensure food to feed their families and wellbeing in this critical period.
The road ahead
With the purpose of advocating this positive transformation in similar conditions, CSISA is committed to expand maize intensification in the plateau region of Odisha and engaging more farmers. Ongoing research and studies are focusing on improving the outreach, to help women increase their maize area and productivity with better-bet agronomy. This will contribute to secured income in coming years and the sustainability of the initiative.

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.
The food security and livelihoods of smallholder farming families in sub-Saharan Africa depend on maize production. The region accounts for up to two-thirds of global maize production, but is facing challenges related to extreme weather events, climate-induced stresses, pests and diseases, and deteriorating soil quality. These require swift interventions and innovations to safeguard maize yields and quality.
In this Q&A, we reflect on the results and impact of the long-term collaborative work on drought-tolerant maize innovations spearheaded by two CGIAR Research Centers: the International Maize and Wheat Improvement Center (CIMMYT) and International Institute of Tropical Agriculture (IITA). This innovative work has changed guises over the years, from the early work of the Drought Tolerant Maize for Africa (DTMA) and Drought Tolerant Maize for Africa Seed Scaling (DTMASS) projects through later iterations such as Stress Tolerant Maize for Africa (STMA) and the newest project, Accelerating Genetic Gains in Maize and Wheat (AGG).
In this Q&A, three leaders of this collaborative research reflect on the challenges their work has faced, the innovations and impact it has generated for smallholder farmers, and possible directions for future research. They are: B.M Prasanna, director of CIMMYT’s Global Maize Program and of the CGIAR Research Program on Maize (MAIZE); Abebe Menkir, a maize breeder and maize improvement lead at IITA; and Cosmos Magorokosho, project lead for AGG-Maize at CIMMYT.
Briefly describe the challenges confronting small-scale farmers prior to the introduction of drought-tolerant maize and how CIMMYT and IITA responded to these challenges?
B.M.P.: Maize is grown on over 38 million hectares in sub-Saharan Africa, accounting for 40% of cereal production in the region and providing at least 30% of the population’s total calorie intake. The crop is predominantly grown under rainfed conditions by resource-constrained smallholder farmers who often face erratic rainfall, poor soil fertility, increasing incidence of climatic extremes — especially drought and heat — and the threat of devastating diseases and insect pests.
Around 40% of maize-growing areas in sub-Saharan Africa face occasional drought stress with a yield loss of 10–25%. An additional 25% of the maize crop suffers frequent drought, with yield losses of up to 50%. Climate change is further exacerbating the situation, with devastating effects on the food security and livelihoods of the millions of smallholder farmers and their families who depend on maize in sub-Saharan Africa. Therefore, the improved maize varieties with drought tolerance, disease resistance and other farmer-preferred traits developed and deployed by CIMMYT and IITA over the last ten years in partnership with an array of national partners and seed companies across sub-Saharan Africa are critical in effectively tackling this major challenge.
A.M.: Consumption of maize as food varies considerably across sub-Saharan Africa, exceeding 100 kg per capita per year in many countries in southern Africa. In years when rainfall is adequate, virtually all maize consumed for food is grown in sub-Saharan Africa, with a minimal dependence on imported grain. Maize production, however, is highly variable from year to year due to the occurrence of drought and the dependence of national maize yields on seasonal rainfall. One consequence has been widespread famine occurring every five to ten years in sub-Saharan Africa, accompanied by large volumes of imported maize grain as food aid or direct imports.
This places a significant strain on resources of the World Food Programme and on national foreign exchange. It also disincentivizes local food production and may not prevent or address cyclical famine. It also leaves countries ill-equipped to address famine conditions in the period between the onset of the crisis and the arrival of food aid. Investment in local production, which would strengthen the resilience and self-sufficiency in food production of smallholder farming families, is a far better option to mitigate food shortages than relying on food aid and grain imports.
C.M.: Smallholder farmers in sub-Saharan Africa face innumerable natural and socioeconomic constraints. CIMMYT, in partnership with IITA and national agricultural research system partners, responded by developing and catalyzing the commercialization of new maize varieties that produce reasonable maize yields under unpredictable rainfall-dependent growing season.
Over the life of the partnership, more than 300 new climate-adaptive maize varieties were developed and released in more than 20 countries across sub-Saharan Africa where maize is a major staple food crop. Certified seed of over 100 stress-tolerant improved maize varieties have been produced by seed company partners, reaching more than 110,000 tons in 2019. The seeds of these drought-tolerant maize varieties have benefited more than 8 million households and were estimated to be grown on more than 5 million hectares in eastern, southern and west Africa in 2020.

In what ways did the drought-tolerant maize innovation transform small-scale farmers’ ability to respond to climate-induced risks? Are there any additional impacts on small scale farmers in addition to climate adaptation?
B.M.P.: The elite drought-tolerant maize varieties can not only provide increased yield in drought-stressed crop seasons, they also offer much needed yield stability. This means better performance than non-drought-tolerant varieties in both good years and bad years to a smallholder farmer.
Drought-tolerant maize varieties developed by CIMMYT and IITA demonstrate at least 25-30% grain yield advantage over non-drought-tolerant maize varieties in sub-Saharan Africa under drought stress at flowering. This translates into at least a 1 ton per hectare enhanced grain yield on average, as well as reduced downside risk in terms of lost income, food insecurity and other risks associated with crop yield variability. In addition to climate adaptation, smallholder farmers benefit from these varieties due to improved resistance to major diseases like maize lethal necrosis and parasitic weeds like Striga. We have also developed drought-tolerant maize varieties with enhanced protein quality — such as Quality Protein Maize or QPM — and provitamin A, which improve nutritional outcomes.
We must also note that drought risk in sub-Saharan Africa has multiple and far-reaching consequences. It reduces incentives for smallholder farmers to intensify maize-based systems and for commercial seed companies to invest and evolve due to a limited seed market.
Drought-tolerant maize is, therefore, a game changer as it reduces the downside risk for both farmers and seed companies and increases demand for improved maize seed, thus strengthening the commercial seed market in sub-Saharan Africa. Extensive public-private partnerships around drought-tolerant maize varieties supported the nascent seed sector in sub-Saharan Africa and has enabled maize-based seed companies to significantly grow over the last decade. Seed companies in turn are investing in marketing drought-tolerant maize varieties and taking the products to scale.
A.M.: The DTMA and STMA projects were jointly implemented by CIMMYT and IITA in partnership with diverse national and private sector partners in major maize producing countries in eastern, southern and western Africa to develop and deploy multiple stress-tolerant and productive maize varieties to help farmers adapt to recurrent droughts and other stresses including climate change.
These projects catalyzed the release and commercialization of numerous stress-resilient new maize varieties in target countries across Africa. Increasing the resilience of farming systems means that smallholder farmers need guaranteed access to good quality stress resilient maize seeds. To this end, the two projects worked with public and private sector partners to produce large quantities of certified seeds with a continual supply of breeder seeds from CIMMYT and IITA. The availability of considerable amount of certified seeds of resilient maize varieties has enabled partners to reach farmers producing maize under stressful conditions, thus contributing to the mitigation of food shortages that affect poor people the most in both rural and urban areas.
C.M.: The drought-tolerant maize innovation stabilized maize production under drought stress conditions in sub-Saharan Africa countries. Recent study results showed that households that grew drought-tolerant maize varieties had at least half a ton more maize harvest than the households that did not grow the drought-tolerant maize varieties, thus curbing food insecurity while simultaneously increasing farmers’ economic benefits. Besides the benefit from drought-tolerant innovation, the new maize varieties developed through the partnership also stabilized farmers’ yields under major diseases, Striga infestation, and poor soil fertility prevalent in sub-Saharan Africa.
How is the project addressing emerging challenges in breeding for drought-tolerant maize and what opportunities are available to address these challenges in the future?

B.M.P.: A strong pipeline of elite, multiple-stress-tolerant maize varieties — combining other relevant adaptive and farmer-preferred traits — has been built in sub-Saharan Africa through a strong germplasm base, partnerships with national research partners and small- and medium-sized seed companies, an extensive phenotyping and multi-location testing network, and engagement with farming communities through regional on-farm trials for the identification of relevant farmer-preferred products.
CGIAR maize breeding in sub-Saharan Africa continues to evolve in order to more effectively and efficiently create value for the farmers we serve. We are now intensively working on several areas: (a) increasing genetic gains (both on-station and on-farm) through maize breeding in the stress-prone environments of sub-Saharan Africa by optimizing our breeding pipelines and effectively integrating novel tools, technologies and strategies (e.g., doubled haploids, genomics-assisted breeding, high-throughput and precise phenotyping, improved breeding data management system, etc.); (b) targeted replacement of old or obsolete maize varieties in sub-Saharan Africa with climate-adaptive and new varieties; (c) developing next-generation climate-adaptive maize varieties with traits such as native genetic resistance to fall armyworm, and introgressed nutritional quality traits (e.g., provitamin A, high Zinc) to make a positive impact on the nutritional well-being of consumers; and (d) further strengthening the breeding capacity of national partners and small and medium-sized seed companies in sub-Saharan Africa for a sustainable way forward.
A.M.: The DTMA and STMA projects established effective product pipelines integrating cutting-edge phenotyping and molecular tools to develop stress-resilient maize varieties that are also resistant or tolerant to MLN disease and fall armyworm. These new varieties are awaiting release and commercialization. Increased investment in strengthening public and private sector partnerships is needed to speed up the uptake and commercialization of new multiple stress-resilient maize varieties that can replace the old ones in farmers’ fields and help achieve higher yield gains.
Farmers’ access to new multiple-stress-tolerant maize varieties will have a significant impact on productivity at the farm level. This will largely be due to new varieties’ improved response to fertilizer and favorable growing environments as well as their resilience to stressful production conditions. Studies show that the adoption of drought-tolerant maize varieties increased maize productivity, reduced exposure to farming risk among adopters and led to a decline in poverty among adopters. The availability of enough grain from highly productive and stress-resilient maize varieties can be the cheapest source of food and release land to expand the cultivation of other crops to facilitate increased access to diversified and healthy diets.
C.M.: The project is tackling emerging challenges posed by new diseases and pests by building upon the successful genetic base of drought-tolerant maize. This is being done by breeding new varieties that add tolerance to the emerging disease and pest challenges onto the existing drought-tolerant maize backgrounds. Successes have already been registered in breeding new varieties that have high levels of resistance to MLN disease and the fall armyworm pest.
Opportunities are also available to address new challenges including: pre-emptively breeding for threats to maize production challenges that exist in other regions of the world before these threats reach sub-Saharan Africa; enhancing the capacity of national partners to build strong breeding programs that can address new threats once they emerge in sub-Saharan Africa; and sharing knowledge and novel high-value breeding materials across different geographies to immediately address new threats once they emerge.

In 1967 Albert O. Hirschman, the pioneering development economist, published Development Projects Observed. Based on an analysis of a handful of long-standing World Bank projects, the book was an effort, as Hirschman writes in the preface, “to ‘sing’ the epic adventure of development — its challenge, drama, and grandeur.” He sang this epic not in the register of high development theory, but rather through the ups and downs and unexpected twists of real-world development projects.
Today, a new group of researchers have taken up a similar challenge. Value Chain Development and the Poor: Promise, delivery, and opportunities for impact at scale, a new book edited by Jason Donovan, Dietmar Stoian and Jon Hellin, surveys over two decades of academic and practical thinking on value chains and value chain development. While value chain development encompasses a broad variety of approaches, it has largely focused on improving the ability of small scale, downstream actors — such as smallholders in agri-food value chains — to capture more value for their products or to engage in value-adding activities. Value chain development approaches have also focused on improving the social and environmental impacts of specific value chains. Donovan, Stoian and Hellin’s book assesses these approaches through careful analysis of real-world cases. The book was published with support from the CGIAR Research Programs on Maize and on Policies, Institutions, and Markets.
Lessons learned
The book takes an unsparing look at what has and hasn’t worked in the field of value chain development. It begins by dissecting the drivers of the high degree of turnover in approaches that characterizes the field. The editors argue that “issue-attention cycles” among project stakeholders, coupled with monitoring and evaluation metrics that are more focused on tracking project implementation rather than producing robust measurements of their social impact, too often lead to the adoption — and abandonment — of approaches based on novelty and buzz.
The unfortunate consequences are that strengths and limitations of any given approach are never fully appreciated and that projects — and even entire approaches — are abandoned before they’ve had a chance to generate deep social impacts. Moreover, the opportunity to really learn from development projects — both in terms of refining and adapting a given approach to local conditions, and of abstracting scalable solutions from real development experiences — is lost.
A recurring theme throughout the book is the tension between the context-sensitivity needed for successful value chain development interventions and the need for approaches that can be scaled and replicated. Programs must develop tools for practitioners on one hand and demonstrate scalability to funders on the other. For example, a chapter on maize diversity and value chain development in Guatemala’s western highlands illustrates how an approach that was successful in Mexico — connecting producers of indigenous maize landraces with niche markets — is ill-suited to the Guatemalan context, where most producers are severely maize deficient. And a chapter reviewing guides for gender-equitable value chain development highlights how — for all their positive impact — such guides often overlook highly context- and culturally-specific gender dynamics. Intra-household bargaining dynamics and local masculinities, for example, can play critical roles in the success or failure of gender-focused value chain development interventions.
This new book takes an unsparing look at what has and hasn’t worked in the field of value chain development.
Finally, while lauding the valuable impact many value chain development initiatives have achieved, the editors warn against an exclusive reliance on market-based mechanisms, especially when trying to benefit the poorest and most marginalized of smallholders. In the case of Guatemala’s maize-deficient highland farmers, for example, the development of niche markets for native maize proved to be a poor mechanism for achieving the stated goal of preserving maize biodiversity and farmers’ livelihoods. Non-market solutions are called for. Based on this and similar experiences, the editors note that, while value chain development can be a valuable tool, to truly achieve impact at scale it must be coordinated with broader development efforts.
“The challenge of ensuring that value chain development contributes to a broad set of development goals requires transdisciplinary, multisector collaboration within broader frameworks, such as integrated rural-urban development, food system transformation, and green recovery of the economy in the post COVID-19 era,” write the editors.
This bracing and clear reflection on the promise and limitations of current development approaches is not only timely; it is perhaps more urgent today than in Hirschman’s time. While tremendous gains have been made since the middle of the 20th century, many stubborn challenges remain, and global climate change threatens to undo decades of progress. Projects like Value Chain Development and the Poor and the ongoing Ceres2030 initiative provide development practitioners, researchers, funders and other stakeholders a much needed assessment of what can be built upon and what needs to be rethought as they tackle these gargantuan challenges.
Embracing uncertainty
At the time Development Projects Observed was published, the study and practice of development was already entering a crisis of adolescence, as it were. Having achieved quasi-independence from its parent discipline of economics, it had to settle on an identity of its own.
Hirschman’s book represented one possible way forward — an understanding of development practice as a blend of art and science. The book’s most famous concept, that of the Hiding Hand, illustrates how planners’ optimism could fuel enormously complex and challenging projects — undertakings that might never have been attempted had all the challenges been known beforehand. At the same time, projects’ inevitable failures and shortcomings could spur creative local responses and solutions, thus ensuring their eventual success and rootedness in their specific context.
As Michele Alacevich points out in the Afterword to the book’s most recent reissue, the World Bank’s response to Hirschman’s book demonstrates the road that development research and practice ultimately took. The book was disregarded, and the Bank turned to the growing literature on cost-benefit analysis instead. “Whereas Hirschman’s analysis had placed uncertainty — an unmeasurable dimension — center stage, cost-benefit analysis assimilated it to risk, therefore turning it into something measurable and quantifiable,” Alacevich writes. Faced with a newfound awareness of the limits to the field’s powers and abilities — a rite of passage for all prodigies — development institutions appeared to try to outrun these limitations through ever-increasing technification.
The issue-attention cycles identified by Stoian and Donovan may represent a new, more frenetic and self-defeating iteration of this discomfort with uncertainty. If so, Value Chain Development and the Poor serves as an urgent call for development institutions and practitioners to make peace with the messiness of their vocation. As Hirschman observed decades ago, only by embracing the uncertainty and art inherent in development work can its students and practitioners further the enormously complex scientific understanding of the endeavor, and, crucially, generate broad and lasting social change.

Maize yields in sub-Saharan Africa are less than a third of what they are in the US—in large part because of drought. A new seed developed by the International Maize and Wheat Improvement Center (CIMMYT) is helping farmers in Africa catch up with their counterparts elsewhere.
