Breaking Ground: P.H. Zaidi helps Asian farmers get healthy harvests despite climate variability

Written by Matthew O'Leary on September 25, 2019. Posted in Features.

Growing up on a rainfed farm in India, P.H. Zaidi learned how smallholder family farmers adapted their farming practices to meet weather challenges, such as dry spells or excessive rain. For the most part, small changes to their crop selection and timing of field operations maintained a wholesome harvest.

As time passed Zaidi witnessed farmers in his hometown and beyond struggling against increasingly extreme and erratic weather events. The Asian tropics have now become hotspots for climate change effects and associated variabilities, said the maize physiologist who works with the Global Maize Program of the International Maize and Wheat Improvement Center (CIMMYT), based in Hyderabad.

“Rainfed farmers produce most of the food for people in Asia, but without sufficient supplemental irrigation systems they are heavily dependent on monsoon rains,” Zaidi said. “Climate variability can be devastating for family farmers who are unable to foresee erratic changes in weather patterns.”

“An extreme weather event can negatively affect household food security and income, which in turn results in a deterioration of capacity to deal with future shocks,” he explained.

Nearly half a billion people in Asia lack access to nourishing food. The Food and Agriculture Organization of the United Nations (FAO) finds climate change-related disasters and a lack of clean water are the main causes of persistent hunger in the region.

Zaidi believes farmers are born innovators and, with the right tools and know-how, they can ensure a healthy harvest despite year-to-year climate variability. He has dedicated his lifework to researching new agricultural technologies that help resource-poor farmers to protect their food and income security.

Stable harvests despite climate change

After getting an undergraduate degree in agricultural science, Zaidi obtained his doctorate at the University of Agriculture Science & Technology in Faizabad, India. He studied how maize physiology interacts with physical stresses, such as severe heat, drought, and excessive moisture. Maize has become an important part of Asian cropping systems, with several countries recording impressive growth rates in maize production and productivity. However, increasing demands — food, feed, and industry — and climate challenges highlight the need for international agricultural research.

In 2002, Zaidi worked as a post-doctoral fellow at CIMMYT in Mexico, where he was mentored by maize abiotic stress experts. He took those research approaches and strategies for breeding stress-resilient maize varieties back home. Working with the Indian government’s maize program, he contributed to developing high-yielding stress-resilient maize for resource-poor maize farmers living in vulnerable agro-ecologies.

With a wealth of knowledge and experience in agricultural systems in Asia, he was employed by CIMMYT as maize physiologist and breeder in 2007. He worked to develop, deploy and scale-out hardy maize varieties that increase yield potential and reduce risk, ensuring a stable harvest despite climate variability. He also developed and standardized screening phenotyping techniques and selection criteria to identify maize germplasm tolerant to stresses including heat, drought and water-logging.

“Through effective collaboration and training, national governments, private seed companies and NGOs are using the varieties with resilient traits in their breeding programs to ensure hardy varieties reach farmers throughout the region,” Zaidi noted.

From 2015 to 2018, a total of 68 such high-yielding stress-resilient maize hybrids were licensed to seed partners in the region, he explained. These partners took them forward for large-scale farmer participatory testing in their respective target ecologies. After extensive testing through the national system, nine stress-resilient maize hybrids have already been released and are being deployed in various countries in Asia. Others will be released soon.

Zaidi has received several awards for his contributions to maize research, including CIMMYT’s Outstanding Scientist Award in 2009.

Remembering Max Alcalá, who led CIMMYT’s wheat international nurseries

Written by Mike Listman on August 29, 2019. Posted in News.

The International Maize and Wheat Improvement Center (CIMMYT) sadly notes the passing of Maximino Alcalá de Stefano, former head of the center’s Wheat International Nurseries service, on August 27. He was 80 years old.

Fondly known as “Max” by friends and colleagues, Alcalá worked at CIMMYT from 1967 to 1992, coordinating wheat international nurseries during the late 1960s and early 1970s. The job included organizing nursery shipments to over 100 partners worldwide each year and collating, analyzing, and sharing results from the nurseries grown.

The printed international nursery report featured an introductory section that described the nurseries, the locations, the statistical analyses used, and an overview of the performance of the breeding lines tested, which comprised the best CIMMYT materials but also germplasm from other sources. The report also carried tables with full data from each location as well as summary tables.

“Max was instrumental in preparing and distributing the printed nursery results, now made available online but which continue to provide crucial input for breeding by CIMMYT and partners,” said Hans-Joachim Braun, director of CIMMYT’s Global Wheat Program. “He also helped start the international nursery database.”

A native of Mexico, Alcalá completed a bachelor’s in Science at the Universidad Autónoma Agraria Antonio Narro in 1964 and a master’s at Texas A&M University in 1967. Alcalá pursued doctoral studies in wheat breeding at Oregon State University under the guidance of renowned OSU researcher Warren E. Kronstad, finishing in 1974.

His professional experience prior to CIMMYT included appointments at Mexico’s National Institute of Agricultural Research (INIA) and in the national extension services.

Later in his career, Alcalá supported wheat training at CIMMYT and helped coordinate visitors services at CIMMYT’s experimental station near Ciudad Obregón, in Mexico’s Sonora state.

The CIMMYT community sends its deepest sympathies and wishes for peace to the Alcalá family.

Breaking Ground: Anani Bruce guards Africa’s maize harvest from insect pests

Written by Mike Listman on August 21, 2019. Posted in Features.

Anani Bruce, maize entomologist at the International Maize and Wheat Improvement Center (CIMMYT) since 2013, is intensively engaged in an expert partnership supporting African maize farmers’ stand against deadly insect pests, especially fall armyworm and stem borers.

A moth species native to the Americas, fall armyworm was detected in Nigeria in 2016 and in less than three years has overrun sub-Saharan Africa’s maize growing regions. At its larval stage, it feeds on leaves and ears, causing annual harvest losses whose value can exceed $6 billion.

Bruce and his colleagues are rushing to develop maize varieties that feature native genetic resistance to fall armyworm and to arm farmers with locally suited control measures. Finding and strengthening native resistance in maize against the pest is a key pillar of integrated pest management.

“The fall armyworm is so challenging that there’s no single, easy fix,” said Bruce, who earned a PhD in Entomology at the International Centre of Insect Physiology and Ecology (ICIPE) and Kenyatta University, Kenya, in 2008. “We are testing and promoting an integrated management approach which, along with host plant resistance, includes biological control, habitat management, good agronomic practices, safe chemicals, bio-pesticides, and botanical controls.”

“The costs and complexities of such practices are daunting, but farmers can learn if you help them and there is little alternative right now, given that maize is sub-Saharan Africa’s number-one staple food,” Bruce explained.

According to the scientist, breeding is also laborious, because potentially resistant maize plants must be tested under controlled, heavy infestations of insects and this is allowed only in net houses.

“Net houses don’t provide enough room to grow the large number of maize lines needed for rapid and effective breeding progress,” Bruce said. “Even so, we have promising leads on sources of moderate resistance from maize populations developed by CIMMYT in Mexico in the 1980s-90s.”

A case of switching environments and specialties

A native of Togo, a small West African country between Benin and Ghana, Bruce said he was first interested in studying mechanical engineering but did not get the opportunity at the University of Lomé, Togo, where he did his master’s studies in agronomy. A mentor instead suggested he pursue entomology, and he followed this up at the International Institute of Tropical Agriculture (IITA) in Cotonou, Benin, where he undertook research on stem borers as a part of his master’s thesis.

“Surprisingly, I found many parallels with mechanical engineering,” said Bruce, who is based at CIMMYT’s office in Kenya. “There is a vast number and diversity of insect species and their roles and interactions in natural systems are incredibly complex, just as occurs between components in mechanical systems.”

When Bruce moved to ICIPE under the African Regional Postgraduate Program in Insect Science (ARPPIS), he needed to add English to his native French and local languages, but said his first major cultural shock was actually dietary.

“In West Africa we usually eat our maize paste with a sauce,” he explained,” but when I sat down to eat in Kenya, I found that the maize paste called ugali was eaten only with milk or meat, a combination known as nyama choma.”

Despite that and other cultural differences, Bruce said he quickly acclimatized to his new work and study setting in eastern Africa.

Nursing maize’s enemies

At CIMMYT, Bruce provides technical backstopping for national research partners to rear maize stem borers and the fall armyworm, as part of breeding improved maize varieties with insect-pest resistance and other relevant traits.

“Special expertise and conditions are required to raise, transport, and apply the eggs or young larvae properly on experimental maize plants, so that infestation levels are as uniform as possible and breeders can identify genetically resistant plants,” Bruce said.

He has also worked with gene constructs from the bacteria known as Bacillus thurigiensis (Bt). When inserted into maize, the constructs bestow the crop with resistance against stem borer species.

“We have plans to deploy Bt maize in selected countries in eastern and southern Africa, but we are awaiting the resolution of regulatory hurdles,” he explained.

Bruce credits Fritz Schulthess, former IITA and ICIPE entomologist, with providing special inspiration and support for his studies and professional development.

“Fritz believes in sharing his scientific experience with upcoming scientists and in speaking his thoughts in black and white,” Bruce said. “He is a workaholic scientist who will review your paper even past midnight and expects your response before 6 am.”

Breaking Ground: Munyaradzi Mutenje tailors innovations to farmers needs

Written by Carolyn Cowan on July 11, 2019. Posted in Features.

Sometimes innovations fail to make an impact. Take 3D televisions, for example; launched at a large scale more than a decade ago, they did not achieve the expected commercial success. On paper, the technology was an affordable and thrilling breakthrough in home entertainment, but in practice many viewers failed to embrace it due to poor implementation. Today, it has largely fallen by the wayside.

Farming innovations can suffer similar fates if product designers do not consider the overall socioeconomic picture during development, warns Munyaradzi Mutenje, an agricultural economist with the Socioeconomics program of the International Maize and Wheat Improvement Center (CIMMYT).

“When the direct seed drill was first launched in Zimbabwe, farmers did not take to it,” Mutenje explains. “Here was a technology that could reduce the drudgery of hand sowing — vastly reducing labor costs and saving time — but no one wanted it. The scientists asked ‘why is no-one adopting this seed drill we designed? It solves so many production challenges… Why don’t people want it?’”

It transpired that women, who constitute a significant portion of the farming community in Zimbabwe, simply found the direct seed drill too heavy and awkward for practical use. They chose to stick with traditional farming methods and were skeptical of the new technology. In short, the product was not designed with the end user in mind.

Design that meets farmers’ needs

Mutenje works in close association with CIMMYT’s sustainable intensification team in Zimbabwe, adding value by opening a dialogue with many different types of farmers. “From the basket of sustainable intensification technologies available, which one is appropriate for each type of farmer?” she asks herself when designing new interventions.

Technologies can seem good to scientists, but they might not be suitable for farmers, who operate within a system of which agriculture is only one component.

“You have to look at the situation from the farmers’ perspective,” Mutenje explains. “In order to assess the economic viability of innovations and to understand how and where to target them, we have to look at factors like social acceptance and cultural barriers that might constrain adoption within farming communities.”

Once technologies are rolled out to farmers, it is vital to seek feedback about the demand for new, and reviews of existing, technologies. This allows scientists to tailor their innovations to the needs and objectives of farmers.

“When we design technologies that meet farmers’ needs because we have interacted with them and understood the whole system; that is our greatest impact.”

All roads lead to CIMMYT

Growing up on a farm in rural Zimbabwe instilled in Mutenje a deep respect for women’s role in agriculture in southern Africa. With her father engaged in off-farm work, her mother tended the farm. She grew curious about household decision-making and was inspired to pursue a career in agricultural science, first studying at the University of Zimbabwe before obtaining her doctoral degree at the University of KwaZulu-Natal in South Africa with a thesis on the effects of AIDS on rural livelihoods.

“I was inspired by the multidisciplinary nature of science and how its application to farming allows scientists to directly help feed people and really transform people’s lives.”

During her undergraduate studies, Mutenje learned from CIMMYT scientists who offered her class practical agronomic examples and taught the students how to apply data analysis to solve complex problems. Fascinated by the power of data to elucidate patterns that can help scientists, she resolved, “One day I will work for CIMMYT to address food and nutritional security issues in southern Africa!”

In 2012, her aspirations became reality as she joined CIMMYT in Zimbabwe as a postdoctoral fellow. Today, she is a CIMMYT scientist.

Work that sparks joy

Working with the CIMMYT sustainable intensification program on projects spanning five countries in southern Africa, Mutenje finds joy in working alongside partners as part of a large team. “You become one big family,” she reflects.

She feels pride in working with smallholder farmers and transforming their livelihoods through science. By boosting the knowledge and potential of women in particular, she believes that sustainable, positive change is possible.

“Women are the custodians of food and nutritional security, so we need to understand their challenges and opportunities. If you help women and offer them training, their impact will go far since they will pass their knowledge on to their children.”

Mutenje carries out a qualitative vulnerability assessment in Bvukuru community, Masvingo province, Zimbabwe, to feed into a study for a project funded by the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA) and Gesellschaft fuer Internationale Zusammenarbeit GmbH (GIZ).

Policy change to help farmers

Although working directly with farmers is what Mutenje enjoys the most, she concedes that prompting widespread change often calls for deeper scrutiny of the value chain, to identify bottlenecks that constrain adoption. Gathering empirical data and presenting evidence of the complete story to policymakers has enabled Mutenje to influence policy change on a national scale.

“In Mozambique, we discovered fertilizer costs were too high for farmers, so they were missing out on a technology that would enable increased yields.”

Mutenje’s work analyzed the whole system and found the import tax on fertilizer component materials was too high and that manufacturers were simply handing that cost down to the farmers. By highlighting this issue to government representatives, she triggered a change in import tax policy. This initiative resulted in fertilizer prices that are affordable to farmers, facilitating improved yields and livelihoods.

“An evidence-based approach, based on quantitative and qualitative data from multiple sources allows scientists to present the complete story,” she explains. “Armed with this, we can convince policymakers to make changes to help farmers and improve food security.”

Derek Byerlee, former director of CIMMYT’s economics program, has been named an Officer of the Order of Australia, the country’s second-highest membership honor, for his distinguished service to sustainable development, poverty reduction, and food security.

The award was among those announced by Australia on June 10, 2019, as part of birthday commemorations for Queen Elizabeth II.

“This was all quite a surprise to me,” said Byerlee, currently an Adjunct Professor at Georgetown University in Washington D.C. and making arrangements to attend the award ceremony in Australia in September.

Byerlee holds CIMMYT in special regard. “CIMMYT was the highlight of my career,” he explained.

Interested in agriculture since his childhood on a sheep and wheat farm near Orroroo in the South Australian Wheat Belt, Byerlee joined CIMMYT in 1977 as one of its first economists, with stints in Mexico and South Asia. He led CIMMYT economics research during 1987-94 and is fondly remembered by colleagues and support staff from that period.

“Derek has made an immense contribution to the developing world and the profession,” said Olaf Erenstein, current director of the CIMMYT socioeconomics program. “He helped put CIMMYT and its economics program on the global map of research for development. His humble yet insightful contributions guided the way for many, including myself.”

Byerlee moved to the World Bank in 1994, heading its support to agricultural research before becoming Rural Strategy Adviser. He later led the team that produced the agency’s influential 2008 World Development Report Agriculture for Development, one of the Bank’s most respected and widely quoted publications and its first ever to focus on agricultural development.

With a Bachelor of Agricultural Sciences from the University of Adelaide, a master’s degree on Agricultural Economics from the University of New England, New South Wales, and a doctoral degree in agricultural economics from Oregon State University, prior to CIMMYT Byerlee worked in the Agricultural Economics program of Michigan State University and at Njala University, Sierra Leone.

Since retiring from the World Bank, he has held diverse consultancy and advisory roles, including Chair of the Standing Panel on Impact Assessment of CGIAR, Member of the Technical Advisory Committee of the Global Agricultural and Food Security Program, and Visiting Scholar at Stanford University.

Byerlee has published widely on agriculture research policy and impacts, farming systems and technology adoption, food pricing policy and land-use changes, and is a Fellow of the American Association of Agricultural Economics.

Author of the 2016 publication, “The birth of CIMMYT: Pioneering the idea and ideals of international agricultural research,” Byerlee has called for a renewed commitment to eliminating hunger through political action at local, national, and international levels, and particularly enjoys teaching about this and related topics at Georgetown University.

“Working with these excellent students gives me a sense of optimism about the future of the world,” Byerlee stated in a recent article in The Flinders News.

Honoring the life and legacy of Fred Palmer

Written by Mike Listman on June 27, 2019. Posted in News.

With sorrow we report the passing on June 14 of Anthony F. E. (Fred) Palmer, former maize agronomist and physiologist who contributed notably to the International Maize and Wheat Improvement Center (CIMMYT) networking and capacity building during crucial periods.

A British national, Palmer joined CIMMYT as a post-doctoral fellow in 1968 and retired from the center in 1996. With undergraduate studies in Agronomy at the University of Reading, Palmer completed masters and doctoral degrees in Crop Physiology at Cornell University. His early years at CIMMYT headquarters included work in maize physiology, agronomy and training.

In 1972 Palmer moved to Pakistan, serving as a production agronomist in that key Green Revolution setting until 1978, when he returned to Mexico as a training officer. “Fred was a true gentleman as a researcher and trainer,” said Stephen Waddington, retired CIMMYT maize agronomist who worked with Fred in Africa. “He was a mentor and friend to many junior CIMMYT staff, including myself, and countless trainees and visiting scientists from partner countries.”

Capitalizing on his experience and accomplishments, in 1985 CIMMYT posted Palmer to Nairobi, Kenya, as the team leader of the East African Cereal Project, funded by the Canadian International Development Agency (CIDA). During the project’s third phase, Palmer helped to establish and guide an entry-level crop management training program, in conjunction with the Kenya Agricultural Research Institute (KARI) and Egerton University, targeting maize researchers from eastern and southern Africa. Based at the university’s Njoro campus, the effort included construction of training facilities and guest rooms and Palmer successfully prepared Egerton administrators and faculty to take over the program, according to Joel Ransom, a North Dakota State University professor who served as a CIMMYT maize agronomist in Asia and sub-Saharan Africa.

“Scores of young agronomists mastered the fundamentals of on-farm research through that program,” Ransom said. “Palmer’s mentoring, training, and leadership greatly advanced the professional development of African maize and wheat scientists.”

Matthew Reynolds, CIMMYT distinguished scientist and wheat physiologist, recalls talking to Palmer about the latter’s efforts to apply fledgling tools for measuring photosynthesis in the field, a topic in which he had specialized at Cornell. “Fred was a very kind and unassuming man who treated everyone with respect, qualities that made him a great training officer and a well-regarded colleague,” said Reynolds.

Palmer firmly believed that national partners needed the capacity to train staff, particularly those fresh out of university studies, strengthening both their knowledge and professional linkages.

“By bringing young scientists together and working with them as a multidisciplinary research team,” Palmer wrote in a report on CIMMYT training in eastern and southern Africa, “it is anticipated that these scientists will learn to value each other’s work as essential to successful research.”

The CIMMYT community sends its warmest condolences to the Palmer family.

Breaking Ground: Mechanization expert Jelle Van Loon goes as far as creativity allows

Written by Emma Orchardson on May 29, 2019. Posted in Features.

In November 2015, Jelle Van Loon set off for Zimbabwe, with a cross-section plan in his backpack. He spent two weeks working with a group of blacksmiths, searching Harare for parts and assembling machines in a bid to test whether the construction plans developed by his team were indeed designed to be built anywhere. “We might have had to change a few things, but three working machines were built, proving the accessibility of the construction plans and inherent replicability of the designs.”

From studying agronomic engineering and crop modelling in Belgium to working on supply chain issues in Peru, Jelle Van Loon amassed a range of experience before joining the International Maize and Wheat Improvement Center (CIMMYT) in 2012. Soon after joining, he began shaping up a team to work on mechanization issues.

“First and foremost I’m an agricultural engineer; I just happen to have a high affinity with mechanics,” he says. “I think my advantage is having a broad knowledge, being able to understand agronomy as well as mechanical engineering, and having studied agricultural economics in developing countries.”

This background has served him well in a role where a hands-on, multidisciplinary approach is crucial.

“Mechanization doesn’t necessarily mean building or creating more machines,” Van Loon explains, “but rather introducing technology and farm equipment to farmers to facilitate their work, as well as supporting them on how and when to use it to increase production efficiency.” Many people also assume that mechanization only involves motorized equipment such as tractors, he adds, when in fact any tool, even simple hand tools, which facilitate farmer work and alleviate drudgery fit into this concept.

CIMMYT’s mechanization team carries out research and development on a range of farm equipment. Team members draw and design prototypes, test them in the field and develop protocols for experiments. Combining agronomy and mechanics, they work to create machinery that supports farmers in their day-to-day work at each stage of the crop cycle: from land preparation, planting and fertilization, to harvest and shelling. They also support the generation of new business models which can deliver appropriate machinery to farmers working within resilient agri-food systems.

Welcome to the machine

One of the biggest challenges is changing the way farmers work. Many are resistant to investing in new machinery because they are unsure of how to use it, and simply cannot afford the risk of failure. As such, the team also places an emphasis on extension work. They have set up centers where growers can learn about the equipment and rent out some model machines. They also build the capacity of service providers through training on functional engineering for blacksmiths and manufacturers, and market intelligence for small sector entrepreneurs.

“It’s beyond just designing the machine. It’s really about taking products out to the field, seeing what works well and where, and then thinking about how we can get these products into the hands of farmers.”

Building on the work being carried out in Mexico, Van Loon is always looking at how other regions can also benefit from the mechanization unit and opportunities for collaborating with colleagues and partners in Africa and Asia. Equipment developed for farmers in Africa or Latin America could be adapted for use in South Asia or vice versa, but this requires a solid understanding of each region’s unique opportunities and challenges.

He points to the example of the two-wheel tractor engine, developed in China and popularized in Asia during the 1980s, when famine and the loss of draft animals prompted governments to subsidize that particular piece of equipment at the right time. The tractor is ubiquitous in countries such as Bangladesh, but it is unclear whether the same success is replicable in Africa and Latin America, neither of which has the same conditions, second-hand markets or import facilities. “We’re trying to learn from cross-regional efforts to scale up. Being able to understand different areas helps us find the weakest links and create more enabling environments,” Van Loon explains.

He and his team are continuously developing and evaluating new ideas, trialing ways of embedding mechatronics or sensory-based technology into their machines to help capture data and ease farmer workloads. Finding a way to keep these low-cost and convenient for farmer use may be a challenge, but positive testimonials from farmers keep him excited about the possibilities.

“I think it’s worthwhile to follow through on wild new ideas and see what happens because when it works out, the positive impact and change we help create is all that matters,” Van Loon notes.

“And more so, the cool thing about working in mechanization is we can go as far as our creativity lets us.”

Investing in diversity

Written by Marta Millere on May 22, 2019. Posted in Videos.

For more than 50 years, CIMMYT has been dedicated to safeguarding and using maize and wheat genetic diversity for the betterment of millions of peoples’ lives around the globe. To accomplish this mission, CIMMYT relies on the diversity of its staff.

Just as there is no future for our food security and health of ecosystems without plant and animal biodiversity, an organization can only go so far without diversity and inclusion. These are no longer trendy keywords, they ensure success. According to recent studies, as organizations become more inclusive — in terms of age, gender, sexual orientation, race — the performance of their staff can skyrocket by 30% or more.

On the occasion of the International Day for Biological Diversity, we sat down with CIMMYT’s Director of Human Resources, Monika Altmaier, to discuss what organizations can do to become better, more resilient and efficient through investing in the diversity of staff.

Q: How do you see CIMMYT using diversity to support its growth and goals?

Monika Altmaier: As a research organization, we need to be innovative to stay relevant. Hiring diversity fosters just that. Different backgrounds provide different approaches, therefore speeding up the process of locating the best solution. According to experts, inclusive organizations are 1.7 times more likely to be innovation leaders in their market. Combining peoples’ diverse perspectives opens doors to innovation.

Employing diverse staff allows us to be more creative, competitive and improves our best practices. It provides a fresh pair of eyes. For me, diversity is an asset that enables us to learn about ourselves and others and grow, as people and professionals. Figuring out how people think and why is so interesting.

Q: What is CIMMYT doing to attract and retain more diverse talent?

MA: We have just finished sharpening our Gender and Diversity in Research and the Workplace policy. This document outlines how CIMMYT integrates gender and social inclusiveness in its research and innovation for development. Also, it describes what needs to be done to promote gender equality and diversity at all stages of employment, from securing new talent to retaining it.

Creating a 360-degree induction in multiple languages for all of our staff has been high on our agenda ever since hearing opinions of staff from 46 countries that gathered at our Science Week last year. This induction course will outline what is expected from everyone at CIMMYT: respect and dignity for all colleagues and stakeholders, regardless of gender identity and expression, disability or health status.

On a monthly basis, when doing outreach, HR post vacancy announcements that are attractive to people from different countries, that use gender-sensitive language and invite everyone, especially women to apply. We include colleagues of different genders, nationalities, and from various research and administration units in the selection and interview process. We scrutinize shortlists and make sure we are giving everyone the same opportunity.

One thing that is harder to change is the market. Still today, in some countries women do not get the same opportunities as men, not to talk about people from marginalized communities and members from the LGBTQ community. I hope that this will change because equality not only helps companies, but also countries, to have a happier population. CIMMYT works closely with universities across the world to make sure that more and more talent trickles where it is most needed: into research for development.

Q: In line with hiring diversity, how is CIMMYT attracting millennial talent (people who are mainly born between 1980 and 2000)?

MA: Millennials are a vast workforce. In just a couple years they will reach the peak of representation in the labor force. There is no issue with attracting millennials: thankfully, our mission resonates with them and they are already working for us across all of our offices.

With this Millennial-centric shift, however, the key thing is to meet the needs that they express. Studies say, and I see this in all of our offices, that young people want a more collaborative approach to work. They want to embrace relationships, transparency, dialogue and creativity.

At CIMMYT’s HR, we are exploring different approaches to talent management and succession planning. Traditionally, one progresses hierarchically. But the world, even the research world, is moving too fast to be satisfied with that. We are currently putting our focus on training, which helps with functional evolution. We are exploring the geographic mobility of staff both within the organization and outside, within our vast network of partners, including those within CGIAR. We are also putting more emphasis on work-life balance, which is said to improve employee retention by more than 50%. In the future, we plan to explore functional mobility, too, and encourage young people to think outside the box they may have preselected for themselves at the beginning of their careers.

Q: What do you think about investing in cognitive diversity?

MA: Cognitive diversity helps teams solve problems faster because it unites people with diverse perspective or information processing styles. Basically, how people think about or engage with new uncertain and complex situations.

It’s not easy to surface cognitive diversity and equally complex to harness its benefits. At CIMMYT, we started with doing psychometric testing when hiring team leaders. These tests are designed to measure candidates’ personality characteristics and cognitive abilities. They show if people would fit in a team. Since then we have expanded to testing research and admin teams. In my experience, such tests are highly trustworthy and interesting, and can help team building.

New role in Nepal is “a dream come true”

Written by Emma Orchardson on May 6, 2019. Posted in Features.

Cynthia Carmona will always remember the directive her supervisor gave to a researcher panicked by mounting paperwork: You go and work on the science. We’ll take care of the admin part.

“They already have their hands full with research and building partnership strategies. They shouldn’t have to be concerned about whether or not an invoice has been sent,” she says.

Growing up in the Mexican state of Sonora, Carmona was aware of the International Maize and Wheat Improvement Center’s (CIMMYT) Obregon experimental station from a young age. “It was an organization that I knew existed, but all I knew was that they worked on wheat.”

After studying international relations at Tecnológico de Monterrey in Mexico City, Carmona spent a couple of years working in government and the private sector but she remained on the look-out for global-facing opportunities. Drawn to the opportunity to work with donors, Carmona joined CIMMYT’s Project Management Unit (PMU) six years ago.

“When I first arrived it was more of a grant management unit and we were divided by grant cycle. One person would work on proposals, another on contracts and so on, so you didn’t really get to see the whole process from start to finish.”

The unit has evolved since then, and growing responsibility means that the team is now divided by specialty, from donor relations and resource mobilization to grant management and monitoring and evaluation. “The structure we have now definitely gives you a broader understanding of each project.”

Carmona stresses that even though PMU staff don’t work in the field or in laboratories, they do make significant contributions to project implementation by encouraging smoother processes, alleviating administrative problems and ‘speaking a common language’ between researchers and management. When she took on the role of grant management coordinator, she impressed upon her team the extent to which their action or inaction could affect the projects they support. “Making things happen was my favorite part of the role, and I saw my job as that of an ‘issue solver’.”

Carmona is currently based in Kathmandu, Nepal, where she is serving as interim project manager on CIMMYT’s Cereal Systems Initiative for South Asia (CSISA) project.

“I’m very excited about this new opportunity. CSISA has always been a flagship project for CIMMYT, so when they invited me to help them it was like a dream come true.”

She first visited Nepal in December 2018, where she spent time shadowing the outgoing manager who provided her with an introduction to the country, the region and the project itself.

“It was like a two-week bootcamp. But even though it was intense, I didn’t feel overwhelmed.”

Working in PMU, Carmona explains, provides a solid background for project management and an understanding of how CIMMYT projects work, from start to finish, as well as how to communicate with funders and build shared knowledge by bringing people together, from scientists and researchers to program and service unit staff.

Besides learning about how a project is run on-the-ground, Carmona is most looking forward to gaining field experience while in Nepal. “Talking to farmers and project teams, listening to their experiences and witnessing CIMMYT’s work on-the-ground really gives you a sense of belonging and a connection to our mission.”

Breaking Ground: Rahma Adam unleashes the agricultural productivity of Africa’s women and youth

Written by Jérôme Bossuet on March 11, 2019. Posted in Features.

Despite great innovations in African agriculture in recent years, much of the continent still struggles to feed itself. With the population growing at an unprecedented rate, avoiding fatal food insecurity lies in the ability to maximize agricultural capacity.

Sociologist Rahma Adam believes there is one vital resource that remains untapped. One which, when unleashed, will not only increase food security but also boost livelihoods: the human capital of Africa’s women and youth.

“Smallholder production and livelihoods are stifled by the unequal access woman and youth have to farming information and resources, compared to men,” said Adam. “Limited access to land and technical services inhibits their agricultural productivity and holds back the food security of all.”

As a gender and development specialist with the International Maize and Wheat Improvement Center (CIMMYT), Adam adds a social inclusion lens to Africa’s development dialogue. Her research asks questions as to why women and youth are overrepresented among the poor and how to improve their access to agricultural training and markets.

The interaction between biology and anthropology has fascinated Adam since she was an undergraduate student at Macalester College. However, it was not until researching women and men in the local food markets of her native Dar es Salaam, Tanzania — as part of an exercise for her master’s degree in Public Policy at Harvard University — that she realized how social equity could improve the livelihoods of all African farmers.

“Working alongside farming women, I saw first-hand the disproportionate number of challenges they face to overcome poverty, gather finance for inputs, produce enough food to sustain a family and improve their livelihoods. However, I also saw their potential,” Adam explained.

Inspired to tackle these complex issues, she got her doctoral degree in rural sociology, with a focus on agriculture, gender and international development, from Pennsylvania State University. Following an early career with nonprofits and the World Bank, she joined CIMMYT as a gender and development specialist in 2015.

Since then, Adam has led research on how best to lift the agricultural productivity of women and youth to its full potential. Working with the Sustainable Intensification for Maize-Legumes Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project, she analyzed the role of gender and social inclusion in maize and legume value chains in Ethiopia, Kenya, Mozambique and Tanzania. She also identified intervention points to achieve gender and age equity across various nodes from field to plate, for example among producers, agrodealers, traders, processors and breeders.

“Promoting women and youth participation in agricultural value chains improves food security and livelihoods,” she explained. “Allowing these groups to have a voice and encouraging their leadership in farmer groups promotes their participation in agriculture.”

Partnerships for social inclusion

In eastern and southern Africa’s maize and legume farming systems, research shows that in most cases men have the final decision over maize crop production. Women have increased decision-making power regarding certain legumes, such as cowpeas and groundnuts, as they are mostly only for household consumption.

Adam’s work with SIMLESA found that promoting women’s participation in the production of legumes as cash crops is an opportunity to empower them, increase their household income and their food security.

Connecting women and youth to value chains through Agricultural Innovation Platforms improves their access to markets, credit, farming information and capacity development, she said. These platforms bring together farmers with extension workers, researchers, agrodealers, and NGO practitioners, so they can work together to improve maize and legume conservation agriculture-based sustainable intensification.

“It is important policy and development decision makers see that research demonstrates entry points to encourage women and youth to take an active role in value chains and improve productivity,” Adam said.

“You don’t want your research to sit on a shelf. This is why science policy dialogues — like the SIMLESA local, national and regional policy forums taking place this year — are important to ensure that research is introduced into the political landscape.”

An inclusive approach to research

Research must be designed and implemented in a way that women and men, including youth, can participate in and benefit from, Adam explained. They need to be considered in the research process, so they can increase their control of productive assets, participate in decision making, and decrease their labor burdens.

Adam has recently joined CIMMYT’s Stress Tolerant Maize for Africa (STMA) project to unpack gender issues in the formal maize seed sector. She will examine the relationship between gender and adoption of drought-tolerant and other improved varieties of maize. Adam will also analyze and categorize the differences in maize trait preferences between male and female farmers, and she will develop materials to integrate gender considerations in formal maize seed sector development.

“This information will be used by breeders to develop new maize varieties which are valuable to farmers and therefore have an increased chance of adoption,” the sociologist explained. “It will also help stakeholders get an idea of the rate men and women adopt improved varieties, and how they contribute to the evolution and performance of the seed sector in eastern and southern Africa.”

Providing training and consultation to her peers on gender and social inclusion is another important component of Adam’s work at CIMMYT. In June she will deliver a webinar on gender in research for CGIAR centers. At the end of the year she will participate in a regional seed sector workshop with other CGIAR experts, seed companies and NGOs, to ensure that partners use gender and social inclusion research.

Funded by the Australian Centre for International Agricultural Research (ACIAR), the SIMLESA project was led by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with the Rwanda Agricultural Board (RAB), CGIAR centers and national agricultural research institutes in Ethiopia, Kenya, Malawi, Mozambique, Tanzania and Uganda. Other regional and international partners include the Queensland Alliance for Agriculture and Food Innovation (QAAFI) at the University of Queensland, Australia, and the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA).

STMA is implemented by CIMMYT and is funded by the Bill & Melinda Gates Foundation and the United States of Agency for International Development (USAID).

Twenty years flew by for Monica Mezzalama, now former Pathologist and Head of the Seed Health Unit at the International Maize and Wheat Improvement Center (CIMMYT). At the end of January 2019, she made her way back to her hometown of Turin, Italy. Looking back at her tenure, Monica told us she felt “overwhelmed” by the opportunities that CIMMYT has given her.

Founded in 1988, the CIMMYT Seed Health lab began with five employees, eventually expanding to eight people. With Mezzalama at the helm since 2001, the unit has become a crucial part of CIMMYT’s operation in conducting global and national germplasm exchanges. Some would say that seed distribution is the “lifeblood” of CIMMYT.

Around the world, CIMMYT is known as a reliable distributor of seeds. According to Mezzalama, this is crucial not only for farmers but for other researchers. Without proper regulatory precautions, one can jeopardize the work of others when handling pathogens that can affect seeds.

CIMMYT distributes seed in collaboration with more than 100 countries worldwide, many of which don’t receive support or seed from any other institution. According to Mezzalama, “CIMMYT’s reputation is on the line,” if healthy, quality seed is not delivered. Under Mezzalama’s watch there were never such problems with CIMMYT seeds.

Seeds are judged on appearances and must be good-looking as well as healthy. “Presentation standards are key because genetics aren’t immediately seen when the seeds are delivered,” Mezzalama states. If unattractive seed is discarded, then money is metaphorically being thrown away. Beyond saving money, quality seed control conducted by the Seed Health Unit helps keep data fresh and research up to date.

Good seed health depends on leadership like that from Mezzalama. Among the accomplishments of her two-decade tenure at CIMMYT, she formed and led a team that has responded quickly and effectively to emerging maize and wheat disease epidemics. In the midst of finding solutions to phytosanitary and biosafety challenges, she also took time to mentor young scientists and colleagues.

Monica Mezzalama will be moving on to the University of Turin in Italy to take on a new challenge in the academic world as a professor of Phytopathology. She expressed sadness at leaving CIMMYT, but gratitude at the opportunities CIMMYT has given her to grow professionally and the freedom to explore and experiment within her laboratory.

Mezzalama’s work and the team she leaves behind provide a strong base for continued safeguarding of CIMMYT’s international seed distribution efforts under her successor’s leadership. Down the road, Mezzalama hopes to maintain collaboration with CIMMYT in sustainable agricultural efforts.

Breaking Ground: Fernando H. Toledo researches new models of analysis under simulated scenarios

Written by Leslie Domínguez on February 14, 2019. Posted in Features.

Genomics is a wide theme of interest for geneticists. As part of the efforts to advance on this subject, Fernando H. Toledo, associated scientist in agricultural statistics at the International Maize and Wheat Improvement Center (CIMMYT), is working on the research of genomic selection models to increase accuracy. His research considers several complex traits and environmental conditions under climate change scenarios.

The research in which Toledo works is multidisciplinary — it involves genetics and breeding knowledge, as well as statistics and computer science. “This work is fundamental for the breeding and farming community. Our aim is to allow breeders to pursue precise selection of new genetic materials with good performance and ensuring food security in the field under varying environmental conditions.”

Fernando H. Toledo was born in São Paulo, Brazil, but grew up in Curitiba, Paraná, one of the biggest agricultural states in the country. He obtained his engineering degree, with a major in crop science, at Paraná Federal University.

He got his master’s degree in genetics and plant breeding at Lavras Federal University, under the supervision of Magno Ramalho, one of the most prestigious breeders in Brazil. During his Ph.D. in quantitative genetics at the Agricultural College of the University of São Paulo, Fernando was advised by Roland Vencovsky, known as the father of quantitative genetics in the country. “The main lesson I took from both of them was that biometrics science must try to answer the breeders’ questions.”

Toledo got a scholarship from the Brazilian National Council for Scientific and Technological Development (CNPq) to spend a season at CIMMYT in 2013, where he developed part of his thesis about the use of selection indices under the supervision of José Crossa.

CIMMYT’s work is highly relevant to breeding activities in Brazil. It dates back to the 1950s when Brazilian breeders and geneticists took maize populations and varieties to be important resources of their current germplasm. “The public and private sectors in Brazil recognize the importance of CIMMYT, which awoke my interest in working in a relevant institute for agriculture in developing countries.”

In 2015, Toledo applied for a postdoctoral position at the Biometrics and Statistics Unit of the Genetic Recourses Program at CIMMYT. He started working as an associate scientist in 2017.

As part of this unit, Toledo is currently involved in the planning and analysis of field trials comprising phenotypic and genomic data. He is developing new models and methods for these analysis as well as plant breeding simulations. “Genomic selection has been used over CIMMYT’s breeding programs before but there are still a lot of improvements to implement, so new models of analysis can be tested under simulated scenarios, which results in better recommendations for breeders.”

On top of that, he is implementing new open-source high-performance software products to facilitate the use of cutting-edge methods for data analysis. “I really like the connection we can build at CIMMYT in terms of practical work for breeders and the development of new statistical methods, models, tools and software we release to attend their requirements, with the main aim of improving precision during the selection of the best genetic materials.”

Led by Juan Burgueño, senior biometrician and head of the Biometrics and Statistics Unit, Toledo is training students, scientists and partners regarding statistical concepts and data analysis. “These trainings courses are a great opportunity to share our work with others and to learn the scientists’ needs in order to improve our capabilities.”

Toledo’s main inspiration to continue his work at CIMMYT is having the opportunity to generate knowledge for others in developing countries. “Our work is driven by the breeders’ needs and that usually helps them to improve their understanding by using what we developed for them and making it a forward-backward relation, which is fascinating.”

Meet the role models for the next generation of women and girls in science

Written by Emma Orchardson on February 8, 2019. Posted in Features.

“We need to encourage and support girls and women to achieve their full potential as scientific researchers and innovators,” says UN Secretary General, Antonio Guterres. And he is right. Bridging the gender gap in science is central to achieving sustainable development goals and fulfilling the promises of the 2030 Agenda.

Unfortunately, this is easier said than done. While in recent years the global community has increased its efforts to engage women and girls in science, technology, engineering and mathematics (STEM), they remain staggeringly underrepresented in these fields. According to UNESCO, less than 30 percent of the world’s researchers are women, and only one in three female students in higher education selects STEM subjects.

“Science is male-dominated,” agrees CIMMYT wheat physiologist Gemma Molero. “It’s challenging being a woman and being young — conditions over which we have no control but which can somehow blind peers to our scientific knowledge and capacity.”

Investing in the science education for women and girls is a key part of changing this reality. Samjhana Khanal, a Nepali agricultural graduate, social entrepreneur and recipient of a 2018 MAIZE-Asia Youth Innovator Award testifies to this. She cites support from her family as a driving factor in allowing her to pursue her education, particularly her mother, who “despite having no education, not being able to read or write a single word, dreamed of having a scientist daughter.”

Enhancing the visibility of established female scientists who can serve as role models for younger generations is equally important.

“One of the most important factors that register subconsciously when undergraduates consider careers is what the person at the front of the room looks like,” claims the Association for Women in Science, “and women and underrepresented minorities visibly perceive their low numbers in fields like engineering and physical sciences.”

*Visiting researcher Fazleen Abdul Fatah is studying the the growing importance of maize and wheat in emerging economies.*

Fazleen Abdul Fatah is a senior lecturer in agricultural economics, trade and policy at Universiti Teknologi MARA (UITM), Malaysia, who recently spent three months as a visiting researcher based at CIMMYT’s global headquarters in Mexico. She acknowledges the importance of raising the visibility of minority female scientists who can serve as role models for young girls by demonstrating that careers in STEM are attainable.

“I had an amazing professor during my undergraduate degree who really inspired me to move forward in the field,” says Abdul Fatah. “She was a wonderful example of how to do great maths, lead successful national and international projects, work in the STEM field, and be a mom.”

With support from CIMMYT, Molero, Khanal and Abdul Fatah are helping pave the way for the next generation of female scientists. Whether working on crop physiology, nutrient management or food consumption patterns, their careers serve as an inspiration for young and early career researchers around the world.

Breaking Ground: Breeder Marcela C. Andrade bolsters maize with hardiness from ancestral races

Written by Mike Listman on January 16, 2019. Posted in Features.

As the world heats up and water grows scarce, threatening the productivity of humankind’s preferred crops, breeder Marcela Carvalho Andrade and her colleagues at the International Maize and Wheat Improvement Center (CIMMYT) are working to toughen maize, drawing resilience traits from landraces, the forerunners of modern maize.

For decades, scientists have sought to utilize the hardiness of maize landraces, which evolved over millennia of farmer selection for adaptation to diverse and sometimes harsh local settings in Mexico, Central and South America.

But crossing elite varieties with landraces brings along wild traits that are difficult and costly to purge, including lower grain yields, excessive tallness or a tendency to fall over in strong winds. For this and for their genetic complexity, landraces are seldom used directly in breeding programs, according to Andrade.

Crosses that home in on genetically complex traits

“Our strategy is to cross selected landraces with elite maize lines, thus developing improved lines that can be directly incorporated and recycled in breeding programs,” explained Andrade, who joined CIMMYT in 2016.

The traits sought include better resilience under high temperatures, drought conditions or the attacks of rapidly-evolving crop diseases. “All these features will be critical for the future productivity of maize,” said Andrade.

One of the world’s three most important crops, maize contributes over 20% of the calories in human diets in 21 low-income countries, as well as being used in industry, biofuels, and feed for livestock and poultry.

Andrade and the maize breeding team develop new lines that carry a 75 percent genetic contribution from the elite source and 25 percent from a landrace. The aim she said is to get the good components from both sides, while broadening maize’s genetic diversity for use by breeders and ultimately farmers.

The resulting lines and hybrids are tested for yield, resilience and overall agronomic performance, under both normal growing conditions and “stressed” environments; for example, in plots grown at sites with high temperatures or reduced water availability.

“We can thus identify landraces that offer traits of interest, as well as generating improved breeding lines to strengthen the resilience of elite maize without reducing its yield,” said Andrade, noting that the research employs conventional cross-pollination and selection.

According to Andrade, CIMMYT has carried out large-scale molecular analysis of its maize seed collections, which number around 28,000 and comprise landraces from 70 countries.

“Over the past years, CIMMYT has used genetic diversity analyses of its maize collections to select landraces for use in drought tolerance breeding or for finding lines that are resistant to newly important diseases such as Maize Lethal Necrosis or Tar Spot,” she explained. “Genetic diversity analysis allows us to narrow the number of candidate landrace sources that we need to cross and assess in the field.”

The viral disease Maize Lethal Necrosis (MLN) has devastated crops in eastern Africa since its appearance there in 2011.

The researchers have also found landrace sources of resilience against Tar Spot Complex, a maize disease of the Americas that can cause 50 percent or greater yield losses in infected crops.

Benefiting breeding and farmers

Andrade said the breeding team expects to release a first wave of landrace-derived, improved maize lines in 2019, some featuring enhanced drought tolerance and others that provide better resistance to Tar Spot.

“The lines we offer will be freely available to breeders worldwide and must yield well and show superior resilience,” Andrade explained. “They will have reasonable agronomics—ear and plant height and standability, for example. The lines will not be perfect, but breeders won’t hesitate to use them because we’ve ensured that they are superior for at least one crucial trait and reasonably competitive for most other traits.”

From Brazil to the world

Growing up in a small town and having direct contact with her father’s dairy farm in Minas Gerais, a mainly rural state in Brazil, Andrade finds her CIMMYT work enormously satisfying. “My dad and a few uncles were farmers and complained some years that their crops didn’t yield well,” she says. “I knew I wanted to help them somehow.”

Andrade obtained Bachelor and Master’s degrees in agronomy/plant science from the Universidade Federal de Lavras (UFLA), one of Brazil’s premier institutions of higher education. She later completed a Doctorate in Genetics and Plant Breeding at UFLA, in partnership with Ohio State University.

She credits CIMMYT maize scientist Terry Molnar, her supervisor and mentor, with teaching her the complex ins and outs of maize breeding. “I am a plant breeder and worked previously with vegetables, but I learned the practical aspects of maize breeding from Terry.”

Looking ahead, Andrade sees herself continuing as a plant breeder. “I don’t see myself working in anything else. I would eventually like to lead my own program but, at this point in my career, I’m happy to help transfer landrace traits to modern maize varieties.”

Breaking Ground: Tek Sapkota finds ways to reduce emissions from agriculture without compromising food security

Written by Rodrigo Ordóñez on December 13, 2018. Posted in Features.

As the world population increases, so does the need for food. “We need to produce more to feed increasing populations and meet dietary demands,” says Tek Sapkota, agricultural systems and climate change scientist at the International Maize and Wheat Improvement Center (CIMMYT). In the case of agriculture, the area of land under cultivation is limited, so increased food production has to come through intensification, Sapkota explains. “Intensification means that you may be emitting more greenhouse gases if you’re applying more inputs, so we need to find a way to sustainable intensification: increase the resilience of production systems, but at the same time decrease greenhouse gas emissions, at least emission intensity.”

Sapkota is involved in a number of global climate change science and policy forums. He represents CIMMYT in India’s GHG platform, a multi-institution platform that regularly prepares greenhouse gas emission estimates at the national and state levels and undertakes relevant policy analyses. Nominated by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and his country, Nepal, he is one of the lead authors of the “special report on climate change and land” of the Intergovernmental Panel on Climate Change (IPCC).

He coordinates climate change mitigation work at CIMMYT. “I am mainly involved in quantification of greenhouse gas emissions and the environmental footprint from agricultural production systems, exploring mitigation options and quantifying their potential at different scales in different regions,” Sapkota says. In addition, he explores low-carbon development activities and the synergies between food production, adaptation and mitigation work within the different components of CIMMYT’s projects.

Agriculture is both a victim of as well as a contributor to climate change, Sapkota explains. “Climate change affects all aspects of food production, because of changes in temperature, changes in water availability, CO₂ concentrations, etc.,” he says. “The other side of the coin is that agriculture in general is responsible for about 25 to 32 percent of total greenhouse gas emissions.”

Measuring emissions and examining mitigation options

A big part of Sapkota’s work is to find ways to mitigate the effects of climate change and the emissions from the agricultural sector. There are three types of mitigation measures, he explains. First, on the supply side, agriculture can “increase efficiency of the inputs used in any production practice.” Second, there’s mitigation from the demand side, “by changing the diet, eating less meat, for example.” Third, by reducing food loss and waste: “About 20 percent of the total food produced for human consumption is being lost, either before harvest or during harvest, transport, processing or during consumption.”

Sapkota and his team analyze different mitigation options, their potential and their associated costs. To that purpose, they have developed methodologies to quantify and estimate greenhouse gas emissions from agricultural products and systems, using field measurement techniques, models and extrapolation.

“You can quantify the emission savings a country can have by following a particular practice” and “help countries to identify the mitigation practices in agriculture that can contribute to their commitments under the Paris climate agreement.”

Their analysis looks at the biophysical mitigation potential of different practices, their national-level mitigation potential, their economic feasibility and scalability, and the country’s governance index and readiness for finance — while considering national food security, economic development and environmental sustainability goals.

Recently, Sapkota and his colleagues completed a study quantifying emissions from the agricultural sector in India and identifying the best mitigation options.

This type of research has a global impact. Since agriculture is a contributor to climate change “better management of agricultural systems can contribute to reducing climate change in the future,” Sapkota says. Being an important sector of the economy, “agriculture should contribute its share.”

Impact on farmers

Sapkota’s research is also helping farmers today. Inefficient use of products and inputs is not only responsible for higher greenhouse gas emissions, but it also costs farmers more. “For example, if farmers in the Indo-Gangetic Plain of India are applying 250 to 300 kg of nitrogen per hectare to produce wheat or rice, by following precision nutrient management technologies they can get similar yield by applying less nitrogen, let’s say 150 kg.” As farmers cut production costs without compromising yield, “their net revenue from their products will be increased.”

Farmers may also get immediate benefits from government policies based on the best mitigation options. “Governments can bring appropriate policy to incentivize farmers who are following those kinds of low-emission technologies, for example.”

Farmers could also get rewarded through payments for ecosystem services or for their contribution to carbon credits.

Sapkota is happy that his work is beneficial to farmers. He was born in a small village in the district of Kaski, in the mid-hills of Nepal, and agriculture was his family’s main livelihood. “I really enjoy working with farmers,” he says. “The most fascinating part of my work is going to the field: talking to farmers, listening to them, learning what kind of farming solutions they’re looking for, and so on. This helps refine our research questions to make them more strategic, because the way farmers look at a problem is sometimes entirely different from the way we look at it.”

When he was in Himalaya Secondary School, he studied agriculture as a vocational subject. “I was interested because we were doing farming at home.” This vocation got cemented in university, in the 1990s. When he heard about the agricultural industry and the future opportunities, he decided to pursue a career in science and focus on agriculture. He got his bachelor’s and master’s degree of science in agriculture from the Institute of Agriculture and Animal Science (IAAS), Tribhuvan University, in Nepal.

*Tek Sapkota (second from left) and other scientists participate in a small group session during a meeting of lead authors of the Intergovernmental Panel on Climate Change (IPCC).*

A global path

He first heard about CIMMYT when he was doing his master’s. “CIMMYT was doing research in maize- and wheat-based plots and systems in Nepal. A few of my friends were also doing their master theses with the financial support of CIMMYT.” After his master’s, he joined an organization called Local Initiatives for Biodiversity, Research and Development (LI-BIRD) which was collaborating with CIMMYT on a maize research program.

Sapkota got a PhD in Agriculture, Environment and Landscapes from the Sant’Anna School of Advanced Studies in Italy, including research in Aarhus University, Denmark.

After defending his thesis, in 2012, he was working on greenhouse gas measurement in the University of Manitoba, Canada, when he saw an opening at CIMMYT. He joined the organization as a post-doctoral fellow and has been a scientist since 2017. Sapkota considers himself a team player and enjoys working with people from different cultures.

His global experience has enriched his personal perspective and his research work. Through time, he has been able to see the evolution of agriculture and the “dramatic changes” in the way agriculture is practiced in least developed countries like Nepal. “When I was a kid agriculture was more manual … but now, a lot of technologies have been developed and farmers can use them to increase the efficiency of farming”.
