KATHMANDU, Nepal (CIMMYT) – Four Nepalese seed companies are showing signs of significant growth, with seed sales increasing nearly 60 percent since 2014.
About 70 percent of Nepal’s population is employed in the agriculture and forestry sector, accounting for 34 percent of the country’s gross national product. While farmers still face many challenges in accessing new technology, market opportunities and other inputs, Nepal’s seed industry is beginning to grow thanks to new investments in seed company operations and facilities. There are currently 20 locally registered seed companies that provide about 50 % of the nation’s formal seed supply system.
The four companies – New Shreeram, Lumbini Seed Company, GATE Nepal Pvt. Ltd. and Unique – are part of a group of 10 Nepalese companies that have worked with the International Maize and Wheat Improvement Center (CIMMYT) through the Cereal Systems Initiative for South Asia (CSISA) since 2014 to improve their marketing and sales strategies, business development, product range and quality.
This growth is notable in Nepal’s emerging cereal seed industry, which is composed primarily of small- to medium-scale enterprises that often lack business plans, have relatively low operating capital and have limited processing and storage facilities. These companies produce open-pollinated crop varieties, which are then released and registered by Nepal’s National Seed Board.
Half of the companies working with CIMMYT have so far been able to secure financial resources of up to $200,000 each from Nepal’s Ministry of Agricultural Development.
“These additional funds have allowed the seed companies to expand their facilities to include seed storage buildings, processing plants and laboratories,” said Upadhaya. “They have also included newly released iron- and zinc-rich varieties in their product lines.”
Some companies have also introduced innovative incentives for their producers by bearing the transportation costs of seed from the farmers’ fields to the company stores as a way to boost sales, according to Upadhaya.
The Seed Entrepreneurs’ Association of Nepal (SEAN) – the seed companies’ umbrella organization – has increased its membership from 600 in 2014 to 1,000 in 2016, formed three regional chapters and contributed a unified voice to discussions around agricultural policies of interest to the seed industry, said Laxmi Kanta Dhakal, SEAN Chairman.
Tons of seed sold from 2014 to 2016.
As a result of these new technologies and investments, seed sold by these companies increased significantly and reached marginal areas of the country through new development networks and private sector traders.
New contractual agreements have since been signed between seed companies, informal groups and cooperatives for the production of seed. As outlined in Nepal’s Agricultural Development Strategy (2015-2025), these initiatives will help promote inclusive growth and an effective seed sector in Nepal.
CIMMYT launched the CSISA in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems. CIMMYT operates rural “innovation hubs” in Bangladesh, India and Nepal to increase the adoption of various resource-conserving and climate-resilient technologies, and to improve farmer access to market information and enterprise development.

Breaking Ground is a regular series featuring staff at CIMMYT
MEXICO CITY (CIMMYT) – As a child helping out on his family’s farm in rural India, Vijay Chaikam dreamed of helping farmers increase the hard won returns of their agricultural labor to improve their livelihoods. Today, he works as a scientist and manager at the International Maize and Wheat Improvement Center (CIMMYT) doubled haploid (DH) facility in Kiboko, Kenya.
He produces DH maize lines, which are highly uniform, genetically pure and stable, making the maize breeding process more intuitive and efficient by simplifying logistics. The outcome of this work is that breeders can develop improved maize varieties faster than ever before so that they can be delivered to the smallholder farmers that need them the most.
“I grew up in a rural village in the state of Andhra Pradesh, India, where my family depended on agriculture for their livelihood,” Chaikam said. “During my childhood, I used to work in the fields, planting, weeding and harvesting alongside my family members to save labor costs. I realized that despite their backbreaking work, most farming families suffer economically. This inspired me to pursue a career in agriculture that would allow me to contribute to reduce the efforts of the farmers and increase their farm income.”
After receiving his doctorate in genetics at West Virginia University in the United States, Chaikam worked at Purdue University and then moved to CIMMYT headquarters in Mexico in 2011 as an associate scientist. His work involved conducting research on developing and implementing maize DH production technology for tropical breeding programs.
In 2016, he moved to CIMMYT’s office in Kenya to manage the Maize DH Facility at KALRO-Kiboko Center, where he assists maize scientists from CIMMYT and partner organizations in the development of DH lines. The efficiency of the DH procedure in maize cuts the time it takes to develop parental lines from six to eight seasons to just two or three seasons.
“My work allows farmers to receive improved maize varieties much quicker,” Chaikam said. “Time is of the essence for farmers planting improved maize varieties in regions affected by stresses such as drought or maize lethal necrosis (MLN). DH technology can drastically cut short the time it takes to derive parental lines in a hybrid maize breeding program.”
CIMMYT’s work on DH has greatly expanded in the past few years. Between 2012 and 2016, CIMMYT scientists produced over 100,000 DH lines, up from less than 5,000 in 2011. However, adoption of the technology is lagging behind in tropical maize breeding programs due to the lack of adapted haploid inducers with high haploid induction rates. The haploid inducers enable generations of haploids – maize varieties containing only one set of chromosomes instead of the usual two sets of chromosomes found in normal diploid maize – at a high frequency. These haploids are then detected using a color marker on the kernel, and the chromosome complement is doubled artificially using treatment with a chromosome doubling agent to derive doubled haploid plants, and consequently seed from those plants.
Chaikam’s current research is aimed at improving the adoption of DH technology in tropical maize breeding programs by developing improved haploid inducers for tropical maize breeding programs, developing novel methods of haploid identification and efficient protocols for chromosomal doubling, and optimizing the agronomic management for deriving doubled haploids. He works closely with breeders to develop ways of using DH lines more efficiently in maize breeding programs. This research could be valuable in the development and deployment of improved maize varieties that benefit smallholder farmers in the developing world. In addition to his work in the DH facility, Chaikam has published several journal articles and book chapters. He has also coordinated scientific training courses.
“I always wanted my work to be relevant to the needs of farmers,” he said, explaining the factors that drew him to work at CIMMYT. “CIMMYT offered such an incredible opportunity, where my day-to-day activities have a direct impact on the development and deployment of improved maize varieties needed by farming communities. I also enjoy working with, talking to and listening to my passionate colleagues who love the work they do to improve the livelihoods of smallholder farmers.”

MEXICO CITY (CIMMYT) — A common platform through which data on genetic resources can be disseminated to both crop researchers and breeders can strengthen research communities, according to authors of a soon to be published Crop Science study.
Conservation and exploitation of crop wild relative species is a key component in ensuring food security and improving current agricultural output. By identifying traits that express resistance or tolerance to stresses like pests or drought, breeders can incorporate this genetic material into genetic background stocks, which could help mitigate problems imposed by climate change, land degradation and population pressure. This is particularly important in countries that will be more severely affected by the threat of reduced yields.
While the underlying species differ, the approach taken ensured that tools were compatible across all database instances. The researchers found that Germinate offers a common platform that can improve the exploration and wider use of genetic resources in breeding programs globally.

DHAKA, Bangladesh (CIMMYT) – A delegation of USAID representatives recently visited southern Bangladesh to learn about sustainable agriculture activities in the area and emerging challenges to wheat production.
Agriculture employs nearly two-thirds of Bangladesh’s population, with a majority of farmers owning land of less than half an acre, putting intense pressure on farmland while having to adapt to various environmental challenges from flooding and rising temperatures due to climate change, to increasing labor scarcity and production costs.
Despite these challenges, Bangladesh has successfully adopted sustainable technologies that conserve natural resources, improve productivity and increase profits, particularly with the two-wheeled tractor that is used by around 80 percent of farmers due to its versatility and ability to be fitted with a variety of additional equipment for planting, threshing and irrigation.
Challenges to widespread adoption of these innovations, however, remain a challenge.

“Much of this innovation has not reached farmers at scale because commercialization has been impeded by the lack of standardization,” according to Andrew McDonald, cropping systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT) and project leader of the CIMMYT-led Cereal Systems Initiative for South Asia (CSISA). “Most workshops create a unique machine every time a new piece is fabricated, which drives up costs to both manufacture and repair the machinery. Quality control is also an issue.”
From March 16-19, the USAID delegation visited farmers and agricultural machinery service providers in the Barisal, Jessore and Jhenaidah districts of Bangladesh, seeing firsthand how CIMMYT is working with NGOs, public and private sector partners to ensure that machinery is scaled, available and affordable to the most marginalized farmers.
The delegation, comprising USAID Senior Program Analyst Charisse Adamson, Water and Irrigation Advisor Biniam Iyob and Food Security Advisor Christopher Chibwana, also learned about various sustainable technologies from axial flow pumps that irrigate crops at reduced cost, to two-wheeled tractors developed by Janata Engineering; a small-scale but rapidly growing agricultural machinery manufacturer, importer and dealer that has been working closely with CSISA over the past seven years.

The visitors also observed how farmers are growing healthy rice seedlings for higher yields in community based seedbeds. Farmer-friendly learning videos are jointly produced by the project with the Bangladesh Rice Research Institute and shown by the Agricultural Advisory Society, with over 35,000 farmers learning about healthy rice seedlings between November 2016 and January this year.
The USAID team then visited the Bangladesh Agricultural Research Institute in Jessore to learn about wheat blast mitigation efforts in the region, which emerged in early 2016. The spread of wheat blast could be devastating to South Asia, which is home to 300 million undernourished people and whose inhabitants consume over 100 million tons of wheat each year.
“I have learned so much…I think you are doing a great job in making research outputs sustainable through strategic value chain pathways,” said Iyob at the end of the visit.

EL BATAN, Mexico (CIMMYT) – Agricultural innovations, like climate-resilient crops, sustainable land use practices and farm mechanization options, can go a long way toward achieving several U.N. Sustainable Development Goals.
But ensuring research reaches a significant amount of farmers to have widespread impact is challenging.
Projects, programs and policies can often be like small pebbles thrown into a big pond. They are limited in scope, time bound and therefore might fail to have long lasting impact. Through well thought scaling up strategies, development practitioners expect to implement successful interventions and expand, adapt and sustain them in different ways over time for greater developmental impact.
Understanding the needs and demands of our stakeholders is crucial in the design and implementation of a research portfolio, he added.
As part of a German Development Cooperation (GIZ) effort to aid the scaling up of agricultural innovations, Lennart Woltering recently joined CIMMYT’s Sustainable Intensification Program. With previous experience working in development in Africa and South Asia, Woltering will play a key role in linking CIMMYT’s research to specific development needs, increasing its relevance and impact.
There is no blue-print for scaling, it depends on the institutional and socio-economic environments, which are very diverse in the various regions where CIMMYT works, said Gérard. He hopes Woltering’s experience with both development and research organizations will further contribute to link the right technical innovations with the people who need them.
Bringing a scaling perspective to research projects as early as possible helps keep a focus on what the project actually can and aims to achieve, Woltering said. Understanding what the drivers are that make widespread adoption happen is critical.
“We do this by making sure scaling processes are an integral part of innovation systems. It is important to understand how conducive environments for scaling can be facilitated and how far we can realistically go,” he added.
Woltering will work to provide a coherent approach to scaling that can be used across the program’s projects, said Gérard.
To see real impact from research, initiatives must move beyond the boundaries of a single organization, Woltering said. New forms of collaboration across different sectors and the opening of new communication channels to share lessons of success when scaling should emerge.
Woltering will develop scaling strategies to facilitate the adoption of sustainable intensification options such as conservation agriculture and water/nutrient efficient practices, and contribute to enhance CIMMYT’s partnerships with public and private sectors.
Previously, Woltering worked as a civil engineer focusing on water management with the International Crops Research Institute for the Semi-Arid Tropics in Africa (ICRISAT), then later moved on to work for a consulting development firm in Germany. His experience will allow him to better articulate development needs with CIMMYT’s research, increasing the relevance and impact of the organization’s work.
Woltering is one of five experts working at CIMMYT as part of the GIZ sponsored CIM Integrated Experts program. The CIM program aims to strategically place managers and technical experts in public and private organizations in the developing world to pass on their professional knowledge and contribute to capacity building.

EL BATAN, Mexico (CIMMYT) – Small-scale agricultural mechanization is showing signs it has the potential to fuel rural employment for youth in sub-Saharan Africa, according to researchers at the International Maize and Wheat Improvement Center (CIMMYT).
Across Africa, youth are struggling with high unemployment and working poverty, the International Labor Organization records. However, increased adoption of agricultural mechanization – especially machines that are small, affordable and easy to maintain such as two-wheel tractors – is stimulating jobs and entrepreneurial opportunities for African youth, said Frédéric Baudron, senior systems agronomist at CIMMYT.
“Small-scale mechanization is more equitable than other forms of mechanization as even the poorest and most vulnerable have access to it,” he said.
Youth, along with women, are typically subject to labor intensive farm activities causing them to shun agriculture. But with mechanization improving productivity while reducing drudgery, youth are seeing economic opportunity in agribusiness, on rural farms and as service providers, said Rabe Yahaya, a CIM/GIZ integrated expert specialized in mechanization for sustainable agriculture intensification.
As a result, new jobs along the value chain from mechanics to spare parts providers have been created, he added.
Relatively cheap and easy to operate two-wheel tractors can be used for many different applications. On-farm, the tractors are used to speed up crop establishment while conserving soils through reduced tillage and precision fertilizer application. They allow farmers to tap into surface water for irrigation as well as aid shelling grain to reduce the time taken to get to market. The machinery has also been used to start rural commercial hire and transport services.

24-year-old Beyene Abebe from Ethiopia is one youth benefiting from mechanization. Through CIMMYT managed training, Abebe has developed the skills needed to become a mechanization service provider. He now provides transportation services for an average of 200 households annually and ploughing services for 40 farmers in his village using two-wheel tractors. With the income from his service, Abebe can cover his family’s expenses and he bought farmland with his savings.
National government support for training and innovation is key to bolster agricultural mechanization throughout Africa, said Baudron. By creating a conductive business environment to attract private sector actors, governments can grease the wheels to scale out success.
Both Yahaya and Baudron shared some insights on the opportunities agricultural mechanization can provide rural communities in the following interview.
Q: Why is it important that agricultural research for development targets youth in rural areas?
RY: A growing population and diet change is increasing food demand in Africa, however, the amount of arable land is decreasing. This affects rural areas, where agriculture remains the main source of income and livelihood. Agriculture in the way it is currently practiced in rural areas is no longer attractive to the new generation of youth as it is labor intensive, rudimentary, risky, unproductive and does not support a good livelihood.
In addition, only 2 percent of Africa’s youth are undertaking agricultural curriculum at the university level. Despite young Africans being more literate than their parents, they suffer from increased unemployment. Agriculture could be the solution in tackling youth unemployment in rural areas, therefore providing peace, stability and food security.
FB: Youth unemployment is growing. Agriculture is perceived as a sector that can absorb much of this unemployment, particularly when combined with entrepreneurship.
In my view, an important issue when tackling issues of sustainable development as opposed to simply ‘development,’ is the issue of equity. We must ensure that the largest amount of people benefit from our interventions. Rural youth represent a large proportion of the vulnerable households in the areas where we work, because they lack capital and other resources, similar to women-headed households.
Q: How is mechanization creating new rural opportunities for youth and women?
RY: In many societies, youth and women are unequally disadvantaged and perform the most labor intensive agricultural activities such as plowing, sowing, weeding, harvesting, shelling, water pumping, threshing and transportation with very rudimentary implements using human and animal power. Therefore, increasing the use of engine power in agriculture will free youth and women from production drudgery discrepancies and most importantly increase farm productivity and consequently improve income generation if an organized value chain exists with a strong private sector involvement.
FB: Mechanization creates rural employment. It creates work for service provider jobs and it also stimulates other businesses along the mechanization value chains. Once demand for mechanization is established, employment opportunities grow for mechanics, fuel providers, savings and loans associations, spare part dealers, etc.
Q: What lessons are there to aid youth to be successful mechanization service providers?
RY: Training in mechanical, agronomic and business skills. Again training and constant follow up is key in order not only to produce successful youth mechanization service provider, but to ensure their continued success. In addition, infrastructure, aftersales — service and spare parts dealerships and financial schemes, promote the adoption of mechanization and support the development of value chain markets are crucial to success.
And remember whatever the technology may be, the farmer has to be able to earn money from it, otherwise they will not use it!
FB: Youth also tend to be better at managing modern technologies. We found consistently, in all countries where we work, that being a successful service provider is highly correlated to be a member of the youth. However, other factors are also important such as being entrepreneurial, educated, able to contribute to the cost of the machinery, and preferably having an experience in similar businesses and particularly in mechanics
Working with CIMMYT’s Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project, researchers have sought to promote the delivery and adoption of small-scale machines to make farming practices – including planting, harvesting, water pumping, shelling and transporting – more productive and sustainable in eastern and southern Africa. Funded by the Australian Center for International Agricultural Research, FACASI offers support throughout the supply chain, from importers to manufacturers, service providers and extension workers to ensure mechanization reaches farmers.
CIMMYT’s mechanization team has ongoing collaboration with GIZ/BMZ green innovation center in Ethiopia and works in Namibia with GIZ to provide knowledge, expertise and capacity building on conservation agriculture.
EL BATAN, Mexico (CIMMYT) – Tending her own crops gives Carolina Camacho insights into the challenges farmers face that she could never have learned in a classroom.
Growing up in the metropolis of Mexico City, the historical and political importance of agriculture was never lost on Camacho, who works as a principal researcher at the International Maize and Wheat Improvement Center (CIMMYT).
“As a teenager, I would debate my sister over the most pressing issue that faced our country, Mexico. For me it was always in agriculture,” Camacho said. “I strongly believe if we are to improve our country, we must improve the lives of our campesinos (smallholder farmers).”
With no knowledge of farming, but with a passion to bring about change, she took to the field, studying crop science at Chapingo University, on the outskirts of the city in the State of Mexico. Having to brave early morning starts, she learned the basics of agriculture, and a love for the genetic diversity of maize.
Mexico, considered the birthplace of maize, is home to a rich diversity of varieties that has evolved over years of domestication by farmers. Camacho was introduced to this diversity firsthand, interning at CIMMYT’s maize germplasm bank as an undergraduate.
Interested in discovering how conserving maize diversity played out in farmers’ fields she gravitated towards an on-farm conservation project in rural Mexico. Working with indigenous farmers, Camacho learned how traditional knowledge and practices relate to environmental management, agricultural production and the diversity of native maize varieties.
After earning a master’s degree in the conservation and utilization of genetic resources, Camacho felt that crop science was isolated from the daily life of farmers. Thus, in a move to study the relationship between humans and plants, she embarked on a multidisciplinary doctoral in the sociology of rural development at Wageningen University in the Netherlands.
While conducting her research, Camacho lived with indigenous farmers in Mexico’s Lacandon rainforest in the state of Chiapas. Alongside local Mayan farmers she cultivated her own milpa – a farming system used by indigenous farmers in Latin America, which typically involves intercropping maize, beans and squash. Her hands-on fieldwork allowed her to study cultivation practices outside the scope of purely agronomic activities, but also as political, social and cultural actions.
“Farming alongside the Tzeltal people, I saw how my own cultivation practices were interwoven with everyday life,” said Camacho. “Farming was influenced by religious ceremonies, health and family affairs as well as political struggles for land. It had to cope, adapt and overcome these challenges.”
Today, these lessons learned guide Camacho as she investigates how agricultural innovations, including drought-tolerant crops, fertilizer and land management approaches can be farmer inclusive and tailored to local contexts as part of CIMMYT’s sustainable intensification strategy for Latin America.
Sustainable intensification aims to enhance the productivity of labor, land and capital. They offer the potential to simultaneously address a number of pressing development objectives, including unlocking the agricultural potential to adapt production systems to climate change, sustainably manage land, soil, nutrient and water resources, improved food and nutrition security, and ultimately reduce rural poverty.

Smallholder farmers, who manage small plots of land and handle limited amounts of productive resources, produce 80 percent of the world’s food. The United Nations calls on these farmers to adopt agricultural innovations in order to sustainably increase food production and help achieve the “Zero Hunger” U.N. Sustainable Development Goal. However, these farmers seldom benefit from new techniques to shore up efforts to meet the goal.
“An agricultural scientist can tell a farmer when and how to plant for optimal results, but they do not farm in a bubble, their practice is affected by the ups and downs of daily life – not only by climate and agronomy but also by social and cultural complexities,” Camacho said.
“One of the biggest challenge is to recognize the heterogeneity of farmers and leave behind the idea of one size solution to their diverse problems and needs,” said Camacho. By understanding a farmer’s lifestyle, including access to resources and information, levels of decision making in the community and the role of agriculture in their livelihood strategy, researchers can best identify complementary farming practices and techniques that not only boost productivity but also improve livelihoods.
“It’s important to think about agricultural innovations as social processes for change in which technologies, like improved seeds or agronomic practices, are only one element,” said Camacho. “It is key that we recognize that changes will not only occur in the farmer’s field but also in the behavior of other actors in the value chain, such as input suppliers, traders, government officials and even researchers.”
Camacho studies how innovations are promoted and adopted in different regions to aid their smooth delivery to farmers and community members from different genders, ethnicities and ages.
When working with indigenous communities, she ensures cultural values of the milpa system are taken into account, thus promoting the agricultural tools and techniques that do not detract from the importance of the traditions associated with the milpa practice.
“The milpa system is a clear example of how agriculture in general and maize in particular contribute to the construction of the cultural identities of indigenous people. We should be aware of the consequences that innovations will have not only for environmental sustainability but also for the sustainability of the Mayan Culture,” she said.
“Let’s not forget, we can’t separate culture from agriculture,” Camacho finished.
Camacho studies the process in which researchers promote agricultural innovations and how farmers adopt them through the Sustainable Modernization of Traditional Agriculture (MasAgro) project, supported by Mexico’s Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA). Together with other researchers, Camacho has documented how MasAgro is promoting innovations in different regions of Mexico by responding to specific regional challenges and opportunities. Currently she is supporting scaling efforts for these innovations by ensuring that they will be sustainable and inclusive.
In the same line of inclusiveness, Camacho is working with two projects in the milpa system. The first one is the Buena Milpa project funded by U.S. Agency for International Development’sFeed the Future program and in collaboration with the Guatemala Agricultural Science and Technology Institute. The second one is the Milpa de Yucatan project sponsored by a private Mexican foundation in Yucatan Peninsula. Both projects promote sustainable intensification innovations in the milpa systems.

EL BATAN, Mexico (CIMMYT) – A comprehensive study of genetic gains resulting from long term breeding work on improved hybrids and open-pollinated varieties (OPVs) in eastern and southern Africa shows that with appropriate funding, maize yields can continue to increase in extreme heat and drought conditions.
Investments into maize breeding and seed systems must expand to keep up with the capacity to withstand climate variability in the region, said Jill Cairns, one of the authors of the study, emphasizing that maize breeding is on track to meet the challenges of climate change in Africa.
The region is currently experiencing large climate variability, including the 2014-2015 drought; the 2015-2016 El Nino and severe drought and flooding in 2016-2017.
“We see evidence that increased investment works,” said Cairns, a maize physiologist with the International Maize and Wheat Improvement Center (CIMMYT) in Zimbabwe. “Although our breeding work has led to higher genetic gains, yields remain lower, reflecting smaller research investments over time. On the other hand, in countries like the United States and China, which have become the top two maize producers worldwide, we see the beneficial impact of steady investments.”
Varieties released by CIMMYT’s partners in sub-Saharan Africa between the years 2000 and 2010, showed that genetic gains for yields made through this improved maize germplasm compare favorably with similar studies in other regions in better growing conditions — in China and the United States, for example.
On average, under optimal conditions, CIMMYT maize breeders increased yields by 109 kilograms per hectare per year, under managed drought conditions, 33 kilograms per hectare per year and under random drought conditions, 23 kilograms per hectare per year. By comparison, in China, under optimal conditions, gains were estimated at 95 kilograms per hectare per year and in the United States, 65 to 75 kilograms per hectare per year.
“Breeding is a long term investment but it ultimately pays off through improved varieties for smallholder farmers,” said Jill Cairns, a maize physiologist with CIMMYT in Zimbabwe, describing the impact of the breeding program in sub-Saharan Africa, which has been underway for more than 30 years.
“We’re constantly changing the breeding pipeline to ensure that the genetic gains are continuously increased,” she added. “Gains are illustrated by sustained increases in grain yield over time. In fact, we expect to see a higher genetic gain through the more recent hybrids developed by CIMMYT maize breeding team than those reported in the study undertaken on hybrids released between 2000 and 2010 because we’ve added a lot of new tools and we are incorporating many new technologies to further increase gains.”
The study confirmed that the lowest genetic gains occurred under low nitrogen conditions where little fertilizer was used, Cairns said, emphasizing the importance of increasing the potential for genetic gains to boost grain yields in areas with poor soil fertility throughout the region.
Scientists working with the CIMMYT maize breeding program primarily focus on developing hybrids, which result from the deliberate crossing of genetically diverse inbred lines that exhibit a wide variety of traits that are relevant for smallholders in the tropics.
Improved OPVs were developed at CIMMYT, using selected sets of inbred lines to reflect traits of the parental lines. In general, genetic gains in the OPVs released during the period under review were found to be higher than for the hybrids, although grain yields in the hybrids were certainly higher.
Resource-poor farmers in some African countries tend to use drought-tolerant improved OPVs, especially where the maize seed sector is weak or improved hybrid seeds are unavailable or unaffordable.
“Accessing hybrid seeds can be a real challenge for resource-poor, smallholder farmers in some areas,” Cairns said. “Hybrids also pose a conundrum for farmers in extremely drought-prone areas, where the tendency is to minimize the risk by using low-cost improved OPVs rather than investing in relatively higher-cost hybrid seeds.”
Yield gain in the CIMMYT-derived hybrids in eastern and southern Africa during the study period is comparable with gains reported in the United States and China. However, absolute yields in the region are still lower, reflecting the opportunity to further improve the yield potential of tropical maize, including in stress-prone environments.
Additionally, maize yields in sub-Saharan Africa, where maize accounts for 50 percent of cereal production in over 50 percent of countries, are still the lowest in the world. National maize yields in 30 countries in the region remain much lower than yields were in the U.S. Corn Belt in 1926 before hybrids were introduced!
Since the CIMMYT breeding program started in Zimbabwe in 1985 (part of the southern Africa region where maize accounts for 45 percent of calories and 43 percent of protein from cereals consumed), scientists have focused on increasing drought tolerance, among other important traits. Currently, the Stress Tolerant Maize for Africa (STMA) project operates in 11 countries across sub-Saharan Africa.
Continual evaluation is a critical component of crop improvement, according to scientists.
“Quantifying genetic gain each year is an integral part of our product development process,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program, and the CGIAR Research Program MAIZE. “This enables us to measure the progress being made, and to make necessary adjustments for continuous improvement of the performance of our products in the target agro-ecologies we serve.”
The research benefits are far-reaching.
In these two first-ever reviews evaluating genetic gains through CIMMYT’s maize breeding program in eastern and southern Africa, we get a clear understanding of benefits and impact of improved maize hybrids and OPVs released during 2000 to 2010, said Marianne Bänziger, who previously led the CIMMYT maize program, and is now deputy director general of research and partnerships at the organization.
“Use of improved seed has been increasing in sub-Saharan Africa and greater uptake is mostly a question of where the seed sector reaches,” Bänziger said. “The issue of variety replacement is complex. Working with governments and seed companies is a key part of our role.”
The dissemination and adoption of drought tolerant maize could generate as much as $590 million for farmers over a seven-year period, Cairns said. “As we take stock of the important role our work has played in this impoverished and environmentally harsh region, we’re grateful for the vital funding we receive from various agencies, especially the Bill & Melinda Gates Foundation, the U.S. Agency for International Development, and the CGIAR research program MAIZE.”

MEXICO CITY (CIMMYT) – A new review of a biological control (BC) program for control of stem borers implemented from 1993 to 2008, in an effort to reduce cereal yield losses due to stemborer attacks in East and Southern Africa, highlights the potential for BC programs to lift a large number of people out of poverty and create greater returns for consumers and producers.
In 1993 the International Centre of Insect Physiology and Ecology program released four biological control agents to control the economically important stem borer pests Busseola fusca, Chilo partellus and Sesamia calamistis. Two of the natural enemies that were released were established and spread throughout the region. The researchers used an economic surplus approach, using bio-agents related data and market data from Kenya, Mozambique and Zambia, to determine the benefits of BC for producers and consumers.
More than 135,000 people were estimated to be lifted out of poverty annually due to the BC intervention, contributing an aggregate monetary surplus of $1.4 billion to the economies of the three countries, with 84 percent from maize production. The study also found that BC research and intervention is very efficient, with an internal rate of return of 67 percent – compared to the considered discount rate of 10 percent – and an estimated benefit-cost ratio of 33:1.
The authors of the study argue that these successful findings underscore the need for increased investment in BC research to sustain cereal production and improve poor living conditions.

EL BATAN, Mexico (CIMMYT) – David Guerena is fascinated by what he learns from smallholder farmers about the interactions between agriculture and the environment.
Guerena’s work involves the strategic planning and execution of multidisciplinary spatial agronomy programs across complex ecologies. In addition to strict biophysical work, which involves integrating chemistry, biology, and physics into agricultural systems, he also engages in socio-economic and market facilitation dynamics research.
“Humanity has been eking out a cultivated living from the earth for around 10,000 years,” Guerena said. “Smallholder farmers are the direct link to this collective knowledge, which has shaped and defined human history. I really enjoy witnessing farmers reap satisfying harvests from their own efforts, but via outputs from agronomic systems research of which I have been a part.”
“Agriculture is intensely satisfying. A seed, fertile soil, water and sunshine eventually turn into food. This is such a simple process, yet millions of people around the world don’t get enough to eat. I draw inspiration from being a part of positively changing this dynamic.”
Originally from Santa Barbara, California, Guerena has always been fascinated by the natural sciences and international travel. He decided to pursue a career in international agriculture by obtaining his Ph.D. from Cornell University, specializing in crop and soil science. Prior to joining CIMMYT, he worked as a soil scientist and agriculture innovations manager at One Acre Fund, served as an international research fellow with the World Agroforestry Center and a Borlaug Fellow in international food security.
CIMMYT provided a unique opportunity for Guerena to work on global food systems. “Together, maize and wheat make up a significant proportion of the global food supply – maize and wheat research is a globally important mandate,” he said. “CIMMYT has also left an indelible mark on human history through facilitating the Green Revolution.”
Currently, Guerena is working on spatial agronomy programs, focusing on questions such as how to move from blanketed to site-specific agronomic recommendations across complex agro-ecologies in the developing world. Guerena will also investigate how digital technologies like SMS, smartphones, image recognition, and remote sensing data can be used and integrated into agronomy programming for smallholder farmers living in poverty.
Precision agronomy, a farming management concept based on observing, measuring, and responding to inter- and intra-field variability in crops, is already transforming agricultural efficiency in the developed world, but these advancements have not yet reached the developing world.
This is of the utmost importance, as worldwide, the vast majority of farmers are smallholders producing most of the global food supply. CIMMYT is not only looking at ways to put its top-level science into the hands of farmers, but also at ways to use these technologies to turn farmers themselves into world-class agronomists. This approach may be a way to bypass cumbersome agricultural knowledge generation and dissemination systems and reach farmers directly, at scale.

MEXICO CITY (CIMMYT) – CIMMYT doctoral student and ETH Zürich graduate Stephanie Cheesman has won the 2017 Hans Vontobel-Preis.
This ETH prize awards 5,000 Swiss Francs ($4,988) annually to the student with the most outstanding thesis in Agricultural Science. The prize is financed by a private fund set up in 1994 by the late banking doyen Hans Vontobel.
The thesis investigated the effects of conservation agriculture (CA) on maize yields and soil carbon stocks, as well as other plant nutrient stocks in the soil. It is based on data collected on 125 on-farm research sites CIMMYT had established between 2004 and 2009 in Malawi, Mozambique, Zambia and Zimbabwe.
The results showed that yields could quickly increase with CA, whereas soil carbon stocks showed – after up to only seven years of CA practice – limited response under the prevailing conditions of Zimbabwe. Farmers also generally adapt CA systems to their conditions rather than adopt the system, due to the fact that there are many more factors besides improved yields – such as preferences in crops grown, availability of inputs and access to other sources of income – that influence why a farmer adopts a technique.

The award panel consisted of Maja Baumann, granddaughter of Vontobel, Bruno Studer, professor and chair of the molecular plant breeding group at ETH Zürich and Sarah Springman, professor and rector of ETH Zürich.
Baumann cited Cheesman’s valuable hard data about conservation agriculture – a topic that has been strongly debated in recent years – and contribution to sustainable agriculture as main reasons for her selection. Further the jury appreciated that the thesis investigated both biophysical and socio-economic aspects, allowing for a better understanding of conservation agriculture’s impact.
Cheesman completed her thesis under the supervision of Emmanuel Frossard, professor at ETH Zürich, CIMMYT Senior Cropping Systems Agronomist Christian Thierfelder and Neal Eash, professor at the University of Tennessee. Professor Johan Six from ETH Zürich evaluated the work as external examiner.
“Stephanie Cheesman’s collaborative project between CIMMYT and the Swiss institutions funded by SDC highlights the strong interest of all organizations to extend sustainable agriculture intensification, with the aim of increasing food and nutrition security and eradicate poverty amongst smallholder farmers in southern Africa,” said Thierfelder.

MEXICO CITY (CIMMYT) – While genetically modified (GM) foods continue to be a topic of debate in much of the developed world, few studies have focused on consumers’ acceptance of GM food in developing countries.
A new study from researchers at the International Maize and Wheat Improvement Center (CIMMYT) used a comprehensive primary dataset collected from 320 consumers in 2013 from Pakistan to analyze the determinants of consumer acceptability of GM foods in the country.
The researchers found that GM foods were more accepted among female consumers as compared to male consumers. In addition, older consumers were more willing to accept GM food compared to young consumers. The acceptability of GM foods was also higher among wealthier households. Low price is the key factor leading to the acceptability of GM foods.

NEW DELHI (CIMMYT) – If women were given the same access to land, seed and other resources as men, they could increase yields on their farm up to 30 percent, reducing the number of hungry people in the world by 150 million. However, large gender disparities in agriculture continue to make it difficult for rural women to access resources and make their own farming decisions.
Climate-smart agriculture (CSA) addresses the interlinked challenges of food security and climate change by sustainably increasing agricultural productivity, building resilience in food-production systems and reducing greenhouse gas emissions in agriculture.
In celebration of International Women’s Day, two events promoting the adoption of CSA technologies and practices among women farmers – like the GreenSeeker sensor, zero tillage farming and others – were organized in the states of Bihar and Haryana, India, representing contrasting agro-ecological and socio-economic regions.
“Linking with CIMMYT-CCAFS, I’ve learned advanced farming techniques, which support better agriculture with increased productivity and profits,” said Ms. Suman, a young farmer from Bastara village in Karnal, India. Suman’s success with climate-smart agriculture inspired women from other villages to begin practicing sustainable farming as well. Photo: CIMMYT
In Bihar, the event was held in collaboration with the Indian Council of Agricultural Research (ICAR)-Research Complex for Eastern Region, Patna and the Borlaug Institute for South Asia and was attended by 80 women farmers from climate smart villages (CSVs), areas that integrate CSA technologies and practices into village development plans, using local knowledge and expertise and supported by local institutions, to help communities adapt to and mitigate the effects of climate change.
Usha Singh, professor of home science at Dr. Rajendra Prasad Central Agriculture University, Bihar, highlighted the role of women in Bihar’s agriculture sector and their contribution to sustainable food production, nutrition and livelihoods. Singh shared home remedies to overcome malnutrition among children and women in rural areas by using their farm produce to prepare balanced diet. R.K. Asthana, animal husbandry scientist with the agricultural extension center Krishi Vigyan Kendra (KVK) in Biroli, emphasized the important role training activities for livestock management can have in improving the socioeconomic status of women in the area.
In Haryana, the event was organized at a climate smart village in Bastara, Karnal in collaboration with the ICAR-Central Soil Salinity Research Institute, which was attended by over 70 women farmers from across several villages. Women shared their experiences under CSVs, discussed ways to increase productivity and profitability, and raise awareness among other women farmers in the area.
HS Jat, CIMMYT senior scientist in Karnal, provided an overview of CIMMYT-CCAFS activities in Haryana and emphasized strengthening and formalizing women groups to enhance knowledge and increase access to resources. CIMMYT event organizers and assistant research associates Munmun Rai and Deepak Bijarniya, and assistant research scientist JM Sutaliya, collectively emphasized the positive impact of CSA interventions in India, which have built farmer resilience to climate change while increasing their productivity and incomes. Deepa Chandra and DK Gosain, program coordinators for National Dairy Research Institute’s KVK in Haryana, also spoke at the event.

MEXICO CITY (CIMMYT) – Marker-assisted recurrent selection (MARS) is helping maize breeders develop higher yielding and drought-tolerant improved varieties faster than ever before, according to a recent study from scientists at the International Maize and Wheat Improvement Center (CIMMYT).
“With conventional breeding, it often takes up to 7-8 years for varieties to reach farmers,” said Yoseph Beyene, a CIMMYT maize breeder working with the CGIAR Research Program on Maize (MAIZE) and one of the authors of the study. “With MARS, those varieties take only 5 years to reach farmers, and display greater genetic gain, even under drought conditions”
The study “Improving Maize Grain Yield under Drought Stress and Non-stress Environments in Sub-Saharan Africa using Marker-Assisted Recurrent Selection” found that by using MARS, breeders can develop new maize varieties farmers need faster and cheaper than conventional breeding methods by reducing the breeding cycle, showing scientists which varieties have desired traits at a quicker rate. This study focused on developing improved, drought-tolerant and high-yielding tropical maize varieties for areas such as sub-Saharan Africa that suffer from frequent drought and an unpredictable climate.
“Climate change is changing environments faster than agriculture can naturally adapt,” said Beyene. “It is crucial that farmers are able to access drought-resistant maize varieties as quickly as possible so that they can adapt to these new conditions,” he said.
MARS also dramatically cuts costs by using genotypic data to predict the best maize varieties before planting them. Previously, breeders would have to visually examine and select the best maize varieties every year.
The study found that MARS can be used to improve maize varieties in both drought and optimum environments throughout sub-Saharan Africa, where it is the most important staple food for over 300 million people. The study used MARS to estimate the genetic gain for 10 biparental tropical maize populations and found that overall, the grain yield for the 10 populations increased by 105 kilograms (kg) per hectare per year under well-watered and 51 kg per hectare per year under water-stressed conditions using MARS. The subsequent generations of test crosses were found to have significantly greater grain yields than their parents and commercial checks, suggesting that MARS has excellent potential for increasing genetic gain under both drought and optimum environments in sub-Saharan Africa.
Over 1,000 improved maize lines, including 352 doubled-haploid lines, have been developed from each cycle of the 10 biparental populations used in this study, and tested in multi-location trials. Several hybrids were derived using lines developed through MARS and pedigree methods. The best hybrids from each population are currently under national performance trials and are expected to be released soon for commercialization in sub-Saharan Africa. CIMMYT is one of the first research organizations to apply this technology to maize breeding specifically for the needs of smallholder farmers.

EL BATAN, Mexico (CIMMYT) – Growing up on a small farm in India’s northwest Punjab state, Kanwarpal Dhugga was a young boy when the first Green Revolution wheat varieties arrived in his village. Now stationed in Mexico as Principal Scientist and head of biotechnology for agricultural development at the International Maize and Wheat Improvement Center (CIMMYT), Dhugga has witnessed vast changes in his boyhood community.
“It was tight for families there, living from season to season with no extra money to spend,” Dhugga said, reflecting on the period during the 1960s before new high-yielding, disease resistant wheat varieties began to reshape agricultural potential throughout Asia. “Farmers used to plant a mixture of wheat and chickpeas. If rains were good, you got good wheat yield; if there was a drought, you got at least chickpeas.”
The use by farmers of the new, high-yielding wheat varieties developed by the late Nobel Peace Prize laureate Norman Borlaug, who was head of the wheat program at CIMMYT headquarters in Mexico, coincided with the introduction of electric power to Dhugga’s area. Electricity enabled pumping underground water for irrigation, making farming more predictable. Within a couple of years, everyone was growing new, more resilient semi-dwarf wheat varieties and yields had increased substantially.
The community was poor and without many educational resources. Dhugga recalls sitting on the ground at elementary school in India and carrying his books in a satchel along with a burlap gunnysack, which he used as a mat to sit on. Despite challenges, his perseverance and determination eventually took him to Punjab Agricultural University, where he earned a master’s degree in plant breeding, then to the University of California, Riverside for a doctoral degree in botany and plant genetics, and finally for a post-graduate degree at Stanford University, where he worked directly with Peter Ray, renowned biologist and now a Stanford emeritus professor.
“I started in genetics and finished in biochemistry,” Dhugga explained. “Science grew on me and I became so fixated that I couldn’t live without it, and that after I had no clue growing up what I wanted to become in life. The vision extended only as far as the next year.”
From 1996 through 2014, he worked at DuPont-Pioneer, the multinational seed producer, where his work included leading research on expressing high-value industrial polymers in maize grains and soybean seeds, developing in-field screening tools to screen maize hybrids for stalk strength, improving nitrogen use efficiency in maize, and on developing a combined genetic marker x metabolites model for predicting maize grain yield, demonstrating that the combined model was more effective than genetic markers alone.
“I was a developer and supplier of advanced plant genetics for a company that was providing high-quality maize seed to farmers around the world, but I felt like something was missing – a social component,” Dhugga said.
Taking a job at CIMMYT, where the focus is on helping improve food security for poor smallholder farmers in the developing world, satisfied this urge, according to Dhugga. “It felt like completing a circle, given where I came from and the role of CIMMYT in improving farmers’ food security and incomes.”
At CIMMYT, he is leading work to apply a recent technology for what is commonly called “gene editing.” Known as the CRISPR-Cas9 system, it allows researchers to enhance or turn off the expression of “native” genes as well as modify the properties of the translated proteins in crops like maize or wheat more simply and effectively than with other methods, including transgenics.
“To deactivate a gene and thus learn about what it does used to be a major undertaking that took years, and even then you didn’t find some of the things you wanted to,” Dhugga explained. “With the new technology, you can find what you’re looking for in much less time. That’s the main focus of my work right now.”
CIMMYT is collaborating with DuPont-Pioneer to fine map, isolate and validate a major gene in maize for resistance to maize lethal necrosis, which appeared in sub-Saharan Africa in 2011 and has caused major losses to maize crops, decreasing food security and the ability of the smallholder farmers to provide for their families.
“We already know a locus that confers high levels of resistance against the combination of viruses that cause the disease,” he said. “Once we have the specific gene, we can edit it directly in elite maize lines used for hybrid production in Africa, eliminating the need for generations of expensive crosses to get uniform lines with that gene.”
Dhugga greatly respects living systems and, rather than viewing his work as inventing new methods, believes he is drawing out the best potential of nature.
“The biology for these processes is already there in nature; we just need to rediscover and apply it to benefit farmers and ensure food security,” he said.
