Uganda is one of the fastest economically growing nations in sub-Saharan Africa and is in the midst of socio-economic transition. Over the past two decades the countryâs GDP has expanded, on average, by more than 6% each year, with per capita GDP reaching $710 in 2019. Researchers project that this will continue to rise at a rate of 5.6% each year for the next decade, reaching approximately $984 by the year 2031.
This growth is mirrored by a rising population and rapid urbanization within the country. In 2019, 24.4% of the Ugandaâs 44.3 million citizens were living in urban areas. By 2030, population is projected to rise to 58-61 million, 31% of whom are expected to live in towns and cities.
âChanges in population, urbanization and GDP growth rate all affect the dietary intake pattern of a country,â says Khondoker Mottaleb, an economist at the International Maize and Wheat Improvement Center (CIMMYT). âEconomic and demographic changes will have significant impacts on the agricultural sector, which will be challenged to produce and supply more and better food at affordable prices.â
This could leave Uganda in a precarious position.
In a new study, Mottaleb and a team of collaborators project Ugandaâs future food demand, and the potential implications for achieving the United Nations Sustainable Development Goal of zero hunger by 2030.
The authors assess the future demand for major food items, using information from 8,424 households collected through three rounds of Ugandaâs Living Standards Measurement Study â Integrated Surveys on Agriculture (LSMS-ISA). They focus on nationwide demand for traditional foods like matooke (cooking banana), cassava and sweet potato, as well as cereals like maize, wheat and rice â consumption of which has been rising alongside incomes and urbanization.

The study findings confirm that with increases in income and demographic changes, the demand for these food items will increase drastically. In 2018, aggregate consumption was 3.3 million metric tons (MMT) of matooke, 4.7 MMT of cassava and sweet potato, 1.97 MMT of maize and coarse grains, and 0.94 MMT of wheat and rice. Using the Quadratic Almost Ideal Demand System (QUAIDS) estimation approach, the authors show that in 2030 demand could be as high as 8.1 MMT for matooke, 10.5 MMT for cassava and sweet potato, 9.5 MT for maize and coarse grains, and 4 MMT for wheat and rice.
Worryingly, Mottaleb and his team explain that while demand for all the items examined in the study increases, the overall yield growth rate for major crops is stagnating as a result of land degradation, climate extremes and rural out-migration. For example, the yield growth rate for matooke has reduced from +0.21% per year from 1962-1989 to -0.90% from 1990-2019.
As such, the authors call for increased investment in Ugandaâs agricultural sector to enhance domestic production capacity, meet the growing demand for food outlined in the study, improve the livelihoods of resource-poor farmers, and eliminate hunger.

Smallholder farmers are often torn between maize seed varieties that have multiple desirable traits. Since they cannot always have it all â there are limits on what traits breeders can integrate in any given variety â 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 farmersâ 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 farmersâ 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 studyâs 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 farmersâ needs and then segmenting the seed markets.
While Marenya argues that prioritization is important for balancing commercial realities and farmersâ diverse interests, he is quick to add that âmarket segmentation has limits imposed by the commercial viability of each segment.â
âAt 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,â Marenya said. âAt 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.â

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.
âThese 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,â 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 âmulti-criteria evaluationsâ 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.

Every year, the spores of the wheat blast fungus lie in wait on farms in South America, Bangladesh, and beyond. In most years, the pathogen has only a small impact on the countriesâ wheat crops. But the disease spreads quickly, and when the conditions are right thereâs a risk of a large outbreak â which can pose a serious threat to the food security and livelihood of farmers in a specific year.
To minimize this risk, an international partnership of researchers and organizations have created the wheat blast Early Warning System (EWS), a digital platform that notifies farmers and officials when weather conditions are ideal for the fungus to spread. The team, which began its work in Bangladesh, is now introducing the technology to Brazil â the country where wheat blast was originally discovered in 1985.
The International Maize and Wheat Improvement Center (CIMMYT), the Brazilian Agricultural Research Corporation (EMBRAPA), Â Brazilâs University of Passo Fundo (UPF) and others developed the tool with support from USAID under the Cereal Systems Initiative for South Asia (CSISA) project.
Although first developed with the help of Brazilian scientists for Bangladesh, the EWS has now come full circle and is endorsed and being used by agriculture workers in Brazil. The team hopes that the system will give farmers time to take preventative measures against the disease.
Outbreaks can massively reduce crop yields, if no preventative actions are taken.
âIt can be very severe. It can cause a lot of damage,â says MaurĂcio Fernandes, a plant epidemiologist with EMBRAPA.
Striking first
In order to expand into a full outbreak, wheat blast requires specific temperature and humidity conditions. So, Fernandes and his team developed a digital platform that runs weather data through an algorithm to determine the times and places in which outbreaks are likely to occur.
If the system sees a region is going to grow hot and humid enough for the fungus to thrive, it sends an automated message to the agriculture workers in the area. These messages â texts or emails â alert them to take preemptive measures against the disease.
More than 6,000 extension agents in Bangladesh have already signed up for disease early warnings.
In Brazil, Fernandes and his peers are connecting with farmer cooperatives. These groups, which count a majority of Brazilian farmers as members, can send weather data to help inform the EWS, and can spread alerts through their websites or in-house applications.
Wheat blast can attack a plant quickly, shriveling and deforming the grain in less than a week from the first symptoms. Advance warnings are essential to mitigate losses. The alerts sent out will recommend that farmers apply fungicide, which only works when applied before infection.
âIf the pathogen has already affected the plant, the fungicides will have no effect,â Fernandes says.
A blast from the past
Because wheat had not previously been exposed to Magnaporthe oryzae, most wheat cultivars at the time had no natural resistance to Magnaporthe oryzae, according to Fernandes.  Some newer varieties are moderately resistant to the disease, but the availability of sufficient seed for farmers remains limited.
The pathogen can spread through leftover infected seeds and crop residue. But its spores can also travel vast distances through the air.
If the fungus spreads and infects enough plants, it can wreak havoc over large areas. In the 1990s â shortly after its discovery â wheat blast impacted around three million hectares of wheat in South America. Back in 2016, the disease appeared in Bangladesh and South Asia for the first time, and the resulting outbreak covered around 15,000 hectares of land. CGIAR estimates that the disease has the potential to reduce the regionâs wheat production by 85 million tons.
In Brazil, wheat blast outbreaks can have a marked impact on the countryâs agricultural output. During a major outbreak in 2009, the disease affected as many as three million hectares of crops in South America. As such, the EWS is an invaluable tool to support food security and farmer livelihoods. Fernandes notes that affected regions can go multiple years between large outbreaks, but the threat remains.
âPeople forget about the disease, then you have an outbreak again,â he says.
Essential partnerships
The EWS has its roots in Brazil. In 2017 Fernandes and his peers published a piece of research proposing the model. After that, Tim Krupnik, a senior scientist and country representative with CIMMYT in Bangladesh, along with a group of researchers and organizations, launched a pilot project in Bangladesh.
There, agriculture extension officers received an automated email or text message when weather conditions were ideal for wheat blast to thrive and spread. The team used this proof of concept to bring it back to Brazil.
According to Krupnik, the Brazil platform is something of a âhomecomingâ for this work. He also notes that cooperation between the researchers, organizations and agriculture workers in Brazil and Bangladesh was instrumental in creating the system.
âFrom this, we’re able to have a partnership that I think will have a significant outcome in Brazil, from a relatively small investment in research supplied in Bangladesh. That shows you the power of partnerships and how solutions can be found to pressing agricultural problems through collaborative science, across continents,â he says.

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 â 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 Coxâs 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’ âoutstanding collaboration that contributed to increased and efficient livestock production through mechanization in the host communities impacted by the influx of Rohingya refugees.â
Mechanization and livestock collaboration
The project â funded by USAID â 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.
âWe made a great collaboration with LPIN,â said Jotirmoy Mazumdar, an agriculturalist working with CSISA-MEA. âWe’re very happy that our initiative helped us achieve this award. In this short time period, a new market opportunity was created.â
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 10â15%. 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 â he expects this to increase to 130 liters per day after feeding them fodder produced with a mechanized chopper.
âHe can now save labor costs and four hours of his time per day by using the fodder chopping solutions,â he said, adding that the collaborative effort is âfostering increased livestock productivity and [farmer] incomes.â
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.
âIn Cox’s Bazar, it was almost impossible for those livestock farmers to get to know the chopper machines, and actually get access to them,â 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.
âFodder choppers are an entirely new technology in Cox’s Bazar,â 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 â each machine can support its owner and five other farmers â 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.
âWe 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,â Khan said.
âWe 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.â

As the world turns its attention to the policy-shaping discussions during this weekâs 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 CIMMYTâs mission, vision and excellence in science to the urgent needs of a world where an estimated tenth of the global population â up to 811 million people â are undernourished.
CIMMYT is also a crucial wellspring of response capacity to CGIAR â 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.
Back-to-back droughts followed by plagues of locusts have pushed over a million people in southern Madagascar to the brink of starvation in recent months. In the worst famine in half a century, villagers have sold their possessions and are eating the locusts, raw cactus fruits, and wild leaves to survive.
Instead of bringing relief, this yearâs rains were accompanied by warm temperatures that created the ideal conditions for infestations of fall armyworm, which destroys mainly maize, one of the main food crops of sub-Saharan Africa.
Drought and famine are not strangers to southern Madagascar, and other areas of eastern Africa, but climate change bringing warmer temperatures is believed to be exacerbating this latest tragedy, according to The Deep South, a new report by the World Bank.
Up to 40% of global food output is lost each year through pests and diseases, according to FAO estimates, while up to 811 million people suffer from hunger. Climate change is one of several factors driving this threat, while trade and travel transport plant pests and pathogens around the world, and environmental degradation facilitates their establishment.
Crop pests and pathogens have threatened food supplies since agriculture began. The Irish potato famine of the late 1840s, caused by late blight disease, killed about one million people. The ancient Greeks and Romans were well familiar with wheat stem rust, which continues to destroy harvests in developing countries.
But recent research on the impact of temperature increases in the tropics caused by climate change has documented an expansion of some crop pests and diseases into more northern and southern latitudes at an average of about 2.7 km a year.
Prevention is critical to confronting such threats, as brutally demonstrated by the impact of the COVID-19 pandemic on humankind. It is far more cost-effective to protect plants from pests and diseases rather than tackling full-blown emergencies.
One way to protect food production is with pest- and disease-resistant crop varieties, meaning that the conservation, sharing, and use of crop biodiversity to breed resistant varieties is a key component of the global battle for food security.
CGIAR manages a network of publicly-held gene banks around the world that safeguard and share crop biodiversity and facilitate its use in breeding more resistant, climate-resilient and productive varieties. It is essential that this exchange doesnât exacerbate the problem, so CGIAR works with international and national plant health authorities to ensure that material distributed is free of pests and pathogens, following the highest standards and protocols for sharing plant germplasm. The distribution and use of that germplasm for crop improvement is essential for cutting the estimated 540 billion US dollars of losses due to plant diseases annually.
Understanding the relationship between climate change and plant health is key to conserving biodiversity and boosting food production today and for future generations. Human-driven climate change is the challenge of our time. It poses grave threats to agriculture and is already affecting the food security and incomes of small-scale farming households across the developing world.
We need to improve the tools and innovations available to farmers. Rice production is both a driver and victim of climate change. Extreme weather events menace the livelihoods of 144 million smallholder rice farmers. Yet traditional cultivation methods such as flooded paddies contribute approximately 10% of global man-made methane, a potent greenhouse gas. By leveraging rice genetic diversity and improving cultivation techniques we can reduce greenhouse gas emissions, enhance efficiency, and help farmers adapt to future climates.

We also need to be cognizant that gender relationships matter in crop management. A lack of gender perspectives has hindered wider adoption of resistant varieties and practices such as integrated pest management. Collaboration between social and crop scientists to co-design inclusive innovations is essential.
Men and women often value different aspects of crops and technologies. Men may value high yielding disease-resistant varieties, whereas women prioritize traits related to food security, such as early maturity. Incorporating womenâs preferences into a new variety is a question of gender equity and economic necessity. Women produce a significant proportion of the food grown globally. If they had the same access to productive resources as men, such as improved varieties, women could increase yields by 20-30%, which would generate up to a 4% increase in the total agricultural output of developing countries.
Practices to grow healthy crops also need to include environmental considerations. What is known as a One Health Approach starts from the recognition that life is not segmented. All is connected. Rooted in concerns over threats of zoonotic diseases spreading from animals, especially livestock, to humans, the concept has been broadened to encompass agriculture and the environment.
This ecosystem approach combines different strategies and practices, such as minimizing pesticide use. This helps protect pollinators, animals that eat crop pests, and other beneficial organisms.
The challenge is to produce enough food to feed a growing population without increasing agricultureâs negative impacts on the environment, particularly through greenhouse gas emissions and unsustainable farming practices that degrade vital soil and water resources, and threaten biodiversity.
Behavioral and policy change on the part of farmers, consumers, and governments will be just as important as technological innovation to achieve this.
The goal of zero hunger is unattainable without the vibrancy of healthy plants, the source of the food we eat and the air we breathe. The quest for a food secure future, enshrined in the UN Sustainable Development Goals, requires us to combine research and development with local and international cooperation so that efforts led by CGIAR to protect plant health, and increase agricultureâs benefits, reach the communities most in need.

The International Maize and Wheat Improvement Center (CIMMYT) is contributing to make Mexicoâs agriculture more productive, sustainable and resilient, according to a new report by The Economist Intelligence Unit and Barilla Foundation.
The study focuses on food loss and waste, sustainable agriculture, and nutritional challenges to assess how sustainable and resilient are the food systems of the 20 largest and most advanced economies of the world, which could lead the way to achieve the United Nationâs Sustainable Development Goals (SDGs) by 2030.
The authors discuss the intricacies between national food systems and progress towards SDGs as a cross-cutting issue: âThe challenge for the agricultural sectors in the G20 countries is to make their production processes more efficient so that they are growing sufficient food for their populations and their exporters, but doing so in a way that is decoupled from resource use, repairs the damage that has already been done to the planet, helps to raise nutritional standards, and in the wake of the pandemic, rebuilds our resilience to the emergence of diseases.â
Against this backdrop, the data systems of CIMMYTâs MasAgro project are identified as an innovation or best practice that helps cut agricultureâs carbon footprint in Mexico. Under Masagro, CIMMYT monitors over 150,000 farmers and more than 500 variables of the growing cycle per farming plot.
âFarmers can then access data analysis via an app which provides them with a range of information to help them improve productivity, use more sustainable practices and access markets,â the report states.

The authors conclude that G20 leaders still have a narrow opportunity to adopt a systems approach to reducing food loss and waste, mitigating the impact of food production on the environment, and increasing the nutritional content of global diets to achieve the SDGs by 2030.
However, the policy responses needed to trigger a transformational change in global food systems require political will and leadership. âInvolving different stakeholders in improving the sustainability of agriculture is key, according to Bram Govaerts of the International Maize and Wheat Improvement Center (CIMMYT),â reads the report.
Today the Board of Trustees of the International Maize and Wheat Improvement Center (CIMMYT) announced leadership changes.
The Board approved the appointment of Martin Kropff, current Director General of CIMMYT, as Global Director of Resilient Agrifood Systems of CGIAR. He will play a critical role in enabling an effective transition to the new structure of CGIAR and implementing the CGIAR 2030 Research and Innovation Strategy. In this role, Kropff will be hosted by the CGIAR System Management Organization and will be based in Montpellier, France.
âWe congratulate Dr. Kropff on his new position. We are convinced that he will bring to CGIAR the same excellence in science, innovation and effective management that he brought to CIMMYT,â said Board of Trustees Outgoing Chair Nicole Birrell, who completes her term in October this year.
âThrough my tenure as CIMMYT Director General, we built a strong and committed team. I am sure that â with the support of the Management Committee, the Executive Committee, the Board, and the three CGIAR Science Group directors â the work of CIMMYT will find a good place in CGIAR,â said Martin Kropff.
New Director General ad interim
Effective July 1, 2021, in accordance with CIMMYTâs Constitution, the Board of Trustees appointed Bram Govaerts as CIMMYTâs Director General ad interim.
Govaerts has been part of the CIMMYT family since 2007. He is Chief Operating Officer and Deputy Director General for Research (Sustainable Production Systems and Integrated Programs) ad interim. He is also the director of CIMMYTâs Integrated Development Program.
Govaerts is renowned for pioneering, implementing and inspiring transformational changes for farmers and consumers in meeting sustainable development challenges. He brings together multi-disciplinary science and development teams to integrate sustainable, multi-stakeholder and sector strategies that generate innovation and change in agri-food systems.
âOn behalf of the full Board, we want to thank Dr. Govaerts for his leadership and willingness to ensure that the Center, our research and our operations continue to run smoothly to serve our mandate and mission, as well as the broader One CGIAR vision,â said Board of Trustees Incoming Chair Margaret Bath.
âThe world needs CIMMYT and our mission now more than ever, to respond to the challenges that are ahead. We are ready to take up this role, as CIMMYT has done ever since Norman Borlaug and his talented team started their work in the service of the poorest. Let us continue celebrating his legacy by generating further impact through our science,â Govaerts said.
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.
A paper titled “Fields on fire: Alternatives to crop residue burning in India” and published in the prestigious journal Science found that working with the Happy Seederâa machine that cuts and lifts the paddy straw while simultaneously sowing the wheat crop and spreading the cut straw as mulch over fieldsâis not just the least polluting, but also the most scalable solution that can be adopted by farmers en masse.
A new guidance note shines a brighter light on the role of women in wheat-based farming systems in the Indo-Gangetic Plains and provides actionable recommendations to researchers, rural advisory services, development partners, and policymakers on how to support working communities more effectively and knowledgeably. The publication, Supporting labor and managerial feminization processes in wheat in the Indo-Gangetic Plains: A guidance note, is based on a literature review, including work by researchers at and associated with the International Maize and Wheat Improvement Center (CIMMYT) and Pandia Consulting.
âFeminization of agriculture is happening in wheat-based systems in South Asia, but these processes are under-researched and their implications are poorly understood. This guidance note, focusing on Bangladesh, India, Nepal and Pakistan, highlights some of the commonalities and differences in feminization processes in each country,â said Hom Gartaula, gender and social inclusion specialist at CIMMYT, and one of the lead authors of the study.
This eight-page publication is based on research funded by the CGIAR Collaborative Platform on Gender Research, the International Development Research Centre (IDRC) and the CGIAR Research Program on Wheat (WHEAT).
How great innovations miss critical opportunities by ignoring women
Even the most well-intentioned agricultural interventions can have external costs that can hinder economic development in the long run. The guidance note cites a study that reveals, during Indiaâs Green Revolution, that the introduction of high-yielding varieties of wheat actually âled to a significant decline in womenâs paid hired labor because wheat was culturally defined as suited to male laborers. Male wages rose, and womenâs wages fell.â Importantly, most women did not find alternative sources of income.
This is not to say that the high-yielding varieties were a poor intervention themselves; these varieties helped India and Pakistan stave off famine and produce record harvests. Rather, the lack of engagement with social norms meant that the economic opportunities from this important innovation excluded women and thus disempowered them.

A closer look at labor feminization and managerial feminization processes
The guidance note points out that it is not possible to generalize across and within countries, as gender norms can vary, and intersectionalities between gender, caste and other identities have a strong impact on womenâs participation in fieldwork. Nevertheless, there seem to be some broad trends. The fundamental cross-cutting issue is that womenâs contribution to farming is unrecognized, regardless of the reality of their work, by researchers, rural advisory services and policymakers. A second cross-cutting issue is that much research is lodged in cultural norms that reflect gender biases, rather than challenge them, through careful, non-judgemental quantitative and qualitative research.
In Bangladesh, womenâs participation in agriculture is slowly increasing as off-farm opportunities decline, though it remains limited compared to women in the other countries examined. Hired agricultural work is an important income source for some women. Emerging evidence from work from CSISA and CIMMYT shows that women are becoming decision-makers alongside their husbands in providing mechanization services. Nevertheless, technical, economic and cultural barriers broadly constrain womenâs effective participation in decision-making and fieldwork.
In India, agricultural labor is broadly feminizing as men take up off-farm opportunities and women take up more responsibilities on family farms and as hired laborers. Yet information derived from CIMMYT GENNOVATE studies cited in the guidance note shows that external actors, like rural advisory services and researchers, frequently make little effort to include women in wheat information dissemination and training events despite emerging evidence of women taking managerial roles in some communities. Some researchers and most rural advisory services continue to work with outdated and damaging assumptions about âwho does the workâ and âwho decidesâ that are not necessarily representative of farmersâ realities.
Women in Nepal provide the bulk of the labor force to agriculture. With men migrating to India and the Gulf countries to pursue other opportunities, some women are becoming de-facto heads of households and are making more decisions around farming. Still, women are rarely targeted for trainings in on-farm mechanization and innovation. However, there is evidence that simple gender-equality outreach from NGOs and supportive extension agents can have a big impact on womenâs empowerment, including promoting their ability to innovate in wheat.
In Pakistan, male out-migration to cities and West Asia is a driving force in womenâs agricultural involvement. Significant regional differences in cultural norms mean that womenâs participation and decision-making varies across the country, creating differences regarding the degree to which their increased involvement is empowering. As in the other three countries, rural advisory services primarily focus on men. This weakens womenâs ability to make good farming decisions and undermines their voice in intra-household decision-making.

Recommendations
Research should be conducted in interdisciplinary teams and mindsets, which helps design both qualitative and quantitative research free of assumptions and bias. Qualitative and quantitative researchers need to better document the reality of womenâs agricultural work, both paid and unpaid.
National agricultural research systems, rural advisory services and development partners are encouraged to work with local partners, including womenâs groups and NGOs, to develop gender-transformative approaches with farmers. Services must develop more inclusive criteria for participation in field trials and extension events to invite more women and marginalized communities.
Policymakers are invited to analyze assumptions in existing policies and to develop new policies that better reflect womenâs work and support womenâs decision-making in the agricultural sector. Researchers should provide policymakers with more appropriate and up-to-date gender data to help them make informed decisions.
These recommendations name a few of many suggestions presented in the guidance note that can ensure agricultural feminization process are positive forces for everyone involved in wheat systems of the Indo-Gangetic Plains. As a whole, acknowledging the reality of these changes well underway in South Asia â and around the world â will not just empower women, but strengthen wheat-based agri-food systems as a whole.

In the plains area of Nepalâs 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 ââ threshing and cleaning ââ 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 number of readily-available farming methods could allow Bangladeshâs agriculture sector to decrease its greenhouse gas emissions while increasing productivity, according to a new study by the International Maize and Wheat Improvement Center (CIMMYT) and partners.
The study, published in Science of the Total Environment, measured the countryâs emissions due to agriculture, and identified and analyzed potential mitigation measures in crop and livestock farming. Pursuing these tactics could be a win-win for farmers and the climate, and the countryâs government should encourage their adoption, the research suggests.
âEstimating the greenhouse gas emissions associated with agricultural production processes â complemented with identifying cost-effective abatement measures, quantifying the mitigation scope of such measures, and developing relevant policy recommendations â helps prioritize mitigation work consistent with the country’s food production and mitigation goals,â said CIMMYT climate scientist Tek Sapkota, who led this work.
To determine Bangladeshâs agricultural greenhouse gas emissions, the researchers analyzed 16,413 and 12,548 datapoints from crops and livestock, respectively, together with associated soil and climatic information. The paper also breaks down the emissions data region by region within the country. This could help Bangladesh’s government prioritize mitigation efforts in the places where they will be the most cost-effective.
âI believe that the scientific information, messages and knowledge generated from this study will be helpful in formulating and implementing the National Adaptation Plan (NAP) process in Bangladesh, the National Action Plan for Reducing Short-Lived Climate Pollutants (SLCPs) and Nationally Determined Contributions (NDC),â said Nathu Ram Sarker, director general of the Bangladesh Livestock Research Institute.
Policy implications
Agriculture in Bangladesh is heavily intensified, as the country produces up to three rice crops in a single year. Bangladesh also has the seventh highest livestock density in the world. In all, the greenhouse gas output of agriculture in Bangladesh was 76.79 million metric tons of carbon dioxide equivalent (Mt CO2e) in 2014-15, according to the research. This emission is equivalent to the emission from fossil fuel burning by 28 million cars for a year. Â At the going rate, total agricultural emission from Bangladesh are expected to reach 86.87 Mt CO2e by 2030, and 100.44 Mt CO2e by 2050.
By deploying targeted and often readily-available methods, Bangladesh could mitigate 9.51 Mt and 14.21 Mt CO2e from its agriculture sector by 2030 and 2050, respectively, according to the paper. Further, the country can reach three-fourths of these outcomes by using mitigation strategies that also cut costs, a boon for smaller agricultural operations.
Adopting these mitigation strategies can reduce the country’s carbon emissions while contributing to food security and climate resilience in the future. However, realizing the estimated potential emission reductions may require support from the countryâs government.
âAlthough Bangladesh has a primary and justified priority on climate change adaptation, mitigation is also an important national priority. This work will help governmental policy makers to identify and implement effective responses for greenhouse gas mitigation from the agricultural sector, with appropriate extension programs to aid in facilitating adoption by crop and livestock farmers,â said Timothy Krupnik, CIMMYT country representative in Bangladesh and coauthor of the paper.
Mitigation strategies
The research focused on eight crops and four livestock species that make up the vast majority of agriculture in Bangladesh. The crops â potato, wheat, jute, maize, lentils and three different types of rice â collectively cover more than 90% of cultivated land in the nation. Between 64 and 84% of total fertilizer used in Bangladesh is used to cultivate these crops. The paper also focuses on the four major kinds of livestock species in the country: cattle, buffalo, sheep and goats.
For crops, examples of mitigation strategies include alternate wetting and drying in rice (intermittently irrigating and draining rice fields, rather than having them continuously flooded) and improved nutrient use efficiency, particularly for nitrogen. The research shows that better nitrogen management could contribute 60-65% of the total mitigation potential from Bangladeshâs agricultural sector. Other options include adopting strip-tillage and using short duration rice varieties.
For livestock, mitigation strategies include using green fodder supplements, increased concentrate feeding and improved forage/diet management for ruminants. Improved manure storage, separation and aeration is another potential tool to reduce greenhouse gas emissions. The mitigation options for livestock would make up 22 and 28% of the total potential emission reductions in the sector by 2030 and 2050, respectively.
