On October 4, 2023, CIMMYT continued its online seminar series — Catalysts of Change: Women Leaders in Science. The event featured a talk by Esther Ngumbi, an entomologist and academic at the University of Illinois Urbana-Champaign.
A riverside farm
Born into a small, rural community on the Kenyan coast, Esther Ngumbi grew up farming alongside her family. “I enjoyed the process of growing crops because I knew at the end of the season, we would have extra food for ourselves,” she explained. By the age of seven she decided she wanted to go it alone, and her father provided a small strip of land by the river, where she took to growing vegetables.
“Every morning I would sit there and just enjoy looking at this thriving cabbage patch I had,” she says. “And then one day the rains came. It rained for three days, the field flooded, and by the time the water receded I had lost my cabbages. The joy that had built was gone.”
“But this heartbreak continued,” she added. “Halfway through the season I would watch all our hard work go to waste.” Along came insects, drought, or flooding—all the stresses associated with climate change—and for her family it would mean no food. Ngumbi soon realized that this was not limited to her family’s farm: her neighbors, community, county, and country were all impacted by these challenges, leading to widespread food insecurity.
Feeding curiosity
“As a girl I was very curious,” said Ngumbi. “How do these insect pests find our crops? And when they find them, why aren’t our crops resilient enough to overcome these stresses? Little did I know that this curiosity would lead me into what my career is today: an entomologist.”
“But growing up in a rural village there were no role models; there were no scientists. There were no people I could look up to and be inspired to know that you could make a career out of entomology or that you could be a woman in science.”
Despite initially considering a career in accountancy, Ngumbi ended up studying for a BSc in biochemistry and zoology at Kenyatta University, where she immediately fell in love with practical research. “Stepping into the lab was such an exciting day for me,” she recalled. “I had so many questions, and I remember not wanting to leave because I wanted to answer all the questions I had grown up with.”
Later, extra-curricular experience at a local research center would feed her interest in entomology. The scientists she ended up working with ran a biological control program to assess how maize is impacted by lepidoptera pests, and the natural biological control agents that could be used to combat these. “How do plants communicate and call for help? Through releasing a chemical. I discovered that there is a wave of communication happening between our food crops and the community of organisms that associate with plants.”
Eager to learn more, Ngumbi went on to pursue an MSc before joining a Ph.D. program at Auburn University in Alabama, USA. “My parents had always told me that education is the gateway out of poverty, and they consistently encouraged me to go to the highest level. I knew I had to go to the top.”
At Auburn she had the opportunity to delve deeper into how plants defend themselves, and her successful research into beneficial soil microbes led to at least three U.S. patents. Following a few post-doctoral positions, she landed a role at the University of Illinois Urbana-Champaign, where she currently works as an assistant professor in the Departments of Entomology and African American Studies.
Bringing others along
Ngumbi credits mentorship with getting her to where she is today. “At Kenyatta University my teachers saw a spark in me; I was curious and wanted to find answers. Mentors introduced me to scientists the International Centre of Insect Physiology and Ecology (ICIPE), so I could carry out experiments beyond what we were doing as part of my course.”
She recalled walking across the stage during her Ph.D. graduation ceremony, a key moment of reflection. “It was real that there were very few women like me in science. That I was only one of the many women I had grown up with that was privileged to have a PhD. And I wanted not to be the only person,” she said. “I wanted to make sure that I would leave open the same door I had walked through. That I would do my best to bring other women along.”
“I would step up to be a mentor. Step up to encourage other women. Step up to encourage other children from rural communities to say: you can do it, you can dream, you can follow your passions, you can be a scientist.”
With this in mind, Ngumbi ensures she collaborates with others in all areas of her research, incorporating young researchers into her labs and working directly with farmers. “I’m committed to ensuring that farmers who work so hard — especially smallholders — can grow crops and see all their hard work pay off.”
“I will continue to follow this journey of finding solutions to feed our growing planet, but I know that I cannot do it alone. We need all of us,” she added. “We still have very few women scientists — UNESCO estimates around 30% — and I hope that by the time I’m done with my career that number changes. But it’s going to depend on all of us.”
Ngumbi’s talk was followed by a Question and Answer led by Olivia Odiyo, a CIMMYT research associate based in Nairobi. The full discussion can be viewed online here. Spanish and French-language audio is also available.
On August 29, CIMMYT held the latest installment of its seminar series on women’s leadership—Catalysts of Change: Women Leaders in Science. The online event featured a presentation from Lindiwe Majele Sibanda, an animal scientist by training, who has previously worked as policy advisor for numerous African governments and global institutions and currently serves as chair of the CGIAR System Board.
In her opening talk, Sibanda outlined the many and varied roles she has held throughout her career, including professor, farmer, and business owner. Discussing her early education in a segregated colonial Zimbabwe (then Rhodesia), her time as an undergraduate student in Egypt, or the challenge of starting a family alongside developing her career, Sibanda was keen to highlight the lessons learned at each stage of life and emphasized the importance of creating cross-cultural friendships, nurturing professional networks, establishing priorities, and promoting continuous learning.
A learning spirit
Sibanda has over 15 years of experience working as a governor at national, regional, and international levels, but it took some time to initially build her confidence in the role. She recalled feeling daunted during her very first meetings because she had not been trained, but her learning spirit helped carry her through. “I always looked around the room and chose my mentors—based on something I liked about their values—something I liked about the way they asked questions, or something I liked about their demeanor and how they engaged with others—and I started learning.”
This approach has garnered her a large circle of mentors—and friends—and having served on more than 12 different boards she now feels this is a space that she enjoys, particularly as there are still opportunities for learning. “I think it’s the spirit of continuous thirst for knowledge, for new information, that has kept me going.”
“And it’s all about integrity,” she added. “What people see in me is what they get. I’ve never had to be fake. What I know, I make sure I know very well. What I don’t know, I’m not shy to say I don’t know.”
Convince each other that it can be done
Having unpacked her life as a scholar, mother, working professional, and governor, Sibanda explained that her current focus is on giving back. For her, supporting the next generation of women in the workplace is a key part of leadership. She cited Graça Machel and Mama Mary Robinson as inspirations, both for their work ethic and their ability to connect with people at different levels. “But most importantly, they give it to other women,” she said. “They love mentoring girls and other women.”
In her own experience, some of the major obstacles she faces as a woman, a farmer, and an African are the specific biases associated with each of those three things. “Women need to be helped, they are disadvantaged; farmers are poor, especially if they come from Africa; and mothers need to spend more time at home and not be globetrotting to meetings.” To counter these biases, she explained, it is important to show that you can thrive and excel in all environments. “It’s not about either or, it’s about showing we can do it, regardless of the circumstances.”
“Women are natural agents of change, and all they need is a conducive environment. As women, we should be spending more time with other women, making sure we share our stories, our successes, and our struggles. The whole idea is to convince each other that it can be done.”
Sibanda’s presentation was followed by a Q&A session led by Ana Luisa Garcia Rivera, senior regional genotyping coordinator at CIMMYT. Watch the recorded session below.
Nepal is an agricultural country, where the sector provides the major source of income for half the population. Despite this, the sad reality is that the country is not able to produce enough crops to meet its needs, and major grains like rice, maize, and cereals are mostly imported.
One factor influencing this is an aging population of farmers, alongside decreasing interest in agriculture among the country’s youth. Many young people do not see agriculture as a viable option for employment, opting instead for work opportunities outside the country. However, there are still some youth who see agriculture as a profitable business, like Pradeep Morya.
“It is better to work hard in your home country rather than going abroad and working tirelessly every minute and hour,” says Morya, a 24-year-old farmer from Banke, Nepal, who finds happiness in living close to his family and helping to support national food security. “I love being in the field,” he explains. “I have cultivated spring maize on one hectare. My day-to-day business is to provide care to the spring maize along with pumpkins and beans that I have added for additional income on a small plot of land.”

Working alongside his eldest brother, Morya has cultivated 30 kattha of land (equivalent to 0.36 hectares) using the spring maize varieties Pioneer 1899 and DK 9108. His brother, a member of Mahatarkari cooperative in Duduwa, western Nepal, has been providing him with the knowledge and expertise needed for maize cultivation.
Mahatarkari is one among 50 cooperatives working in partnership with the Nepal Seed and Fertilizer project (NSAF), which is implemented by CIMMYT. NSAF works with the cooperatives to provide technical knowledge and training to farmers, to hone their potential and support them in the adoption of modern technologies which can improve their livelihoods. After participating in programs organized by NSAF, Morya makes sure that the suggestions he receives — on soil preparation, weed management, harvesting, and more — are implemented in his field.
Returning to the family farm
A few years back, the situation was different. Like many youths in the country, Morya also went abroad to try his luck on the international job market. He worked hard for two years in Malaysia but was forced to return to Nepal during the COVID-19 pandemic.
“I had imagined my shining future abroad. However, when I reached there, the reality was different,” recalls Morya. “I returned to my own country just before the lockdown in April 2021 with some small savings. Upon my arrival in Nepal, I was clueless about my future. I dropped my education after grade five. With no educational qualifications and skills in hand, it was difficult to get a decent job.”

Since the country was in lockdown, Morya chose to stay at home and support his family on the farm. It was here that his eldest brother guided him into farming, and Morya soon learned the knowledge needed to run the farm and began earning money from it. This attracted him towards farming as a longer-term career option, and he has now discovered a prosperous future in agriculture.
“Agriculture needs continuous effort,” he says. “With the support of technology, it is easy and efficient to work. I work every day so that I can reap crops on a large scale to make a profit. I manage weeds, irrigation, and control pests.”
“I also have livestock. I get adequate fodder for my cows and buffalo from weeds and from the spring maize. I sell milk in the market. In addition to this, I also make sure to produce off-season vegetables so that I receive a decent price for additional income.” With the support of his family, Morya has recently purchased an e-rickshaw, which he uses to transport and sell his produce.
To further support his endeavors, Morya has also been participating in Nepal’s Maize Commercialization Network and using the Geo Krishi mobile app to learn about current market prices. “Before knowing about the commercialization of crops, it was hard to receive good amounts from buyers,” he explains. “Now, I make a call to the local retailers and buyers to learn the best value of my grain. Sometimes I also explore the market. Then, I analyze the rate and sell my maize.” He uses a similar system for his off-season vegetables, selling either in the local market or directly to consumers for a premium price. “I make a saving of around 1500 Nepalese rupees (approximately US$ 11) per day,” he says.
A prosperous life
With the profits from his agricultural business, Morya has been able to fulfill his dream of purchasing a bike, as well as contributing to the construction of a new eight-room house, where his family is now living comfortably. “I love to roam on my bike with my friends in the evening. I also take my mother for a ride,” says Morya with a bright smile. “Now, I have a dream to live a prosperous life with my family.”

Thanks to the support provided by the NSAF project with generous funding from USAID, young people like Morya can pursue a better life for themselves and their families. Agricultural training programs have not only helped young people fulfill their basic needs, but also to achieve their dreams. It is hoped that ongoing efforts to empower farmers through science and innovation will continue helping young farmers like Morya break the chain of unemployment, for both their own benefit and that of Nepal.
French Gates believes initiatives to improve gender equality “treats symptoms, not the cause”, which is why the International Maize and Wheat Improvement Center (CIMMYT) incorporates gender equality work into each project. Social norms and gender-based labor division mean women are often confined to set roles in agricultural production, leading to exclusion from decision-making and a lack of control over their economic wellbeing and household food security. Across CIMMYT’s work in the Global South, researchers are addressing multiple aspects of gender inequality.
Training shows women their power
Rina Begum, Nilufar Akter and Monika Rani are Bangladeshi women supported by CIMMYT to achieve their highest economic potential. Developing their business acumen enabled the women to take on essential roles in the workplace, establish themselves in their communities, and fund their children’s education.
CIMMYT-led workshops helped the women grow their self-confidence and identify where their skills and knowledge could enhance their economic situations. In turn, they are keen to help more women access the same opportunities for independence and growth.
“I used to think I wasn’t cut out for light engineering because it was primarily male-dominated, but I was mistaken”, confessed Akter. “This industry has a lot to offer to women, and I’m excited at the prospect of hiring more of them.”
“When women have economic means in their own hands—not just cash, but in an account that they control—it unlocks all kinds of things for their lives,” French Gates says.
Adapting research methods to women’s needs
CIMMYT’s Accelerating Genetic Gains in Maize and Wheat (AGG) project is designing a better framework for faster turnover of improved varieties and increased access for women and marginalized farmers. However, traditional data collection methods may not be suitable for understanding the true experiences of rural women.
Instead, researchers have adapted their data collection methods to cultural restrictions, where women may feel unable to talk openly. Instead of a traditional survey, the team used five vignettes that explore how the production and consumption decisions are held within the households. Respondents then chose the scenario that best represents their own experiences.
Providing opportunities for women to tell their stories in more accessible ways will lead to richer qualitative data, which can improve the development and implementation of gender interventions.
Climate change and gender equality
For International Day of Women and Girls in Science this year, researcher Tripti Agarwal shared her research on the impact of Climate-Smart Agricultural Practices (CSAPs) on women and farming households in Bihar, India. The region is at risk of natural disasters, causing agricultural production loss and food insecurity – with women’s food security more severely affected.
Climate-Smart Villages (CSVs) could offer a solution by acknowledging the gender gap and promoting gender-equitable approaches in enhancing knowledge, developing capacity and improving practices. Through the adoption of climate-resilient practices and technologies, CSV reduces the risk of crop loss and ensures there is enough food for the household.
Agarwal also highlights the work that men must do to level the playing field. “When we talk about women, especially in rural/agricultural contexts, we see that support from the family is critical for them,” said Agarwal. “Creating plans and roadmaps for women would help achieve a gender-empowered agricultural domain, but we must also bring behavior change among men towards a more accepting role of women in farming and decision making.”

Careers for women in science
CIMMYT’s global presence provides opportunities for women to launch and grow their careers in science, technology, engineering, and mathematics (STEM).
Madhulika Singh, an agricultural scientist with CIMMYT’s Cereal Systems Initiative for South Asia (CSISA) project, made what was seen as a radical choice to study a STEM subject. She was inspired by seeing other women in her family build successful careers, showing the power of role models in inspiring the next generation. “I grew up thinking ‘there is so much that a woman is capable of,’ whether at home or her workplace,” said Singh.
Initiatives such as CIMMYT’s Women in Crop Science group also help to highlight role models, create mentorship opportunities, and identify areas for change. The group recently received the Inclusive Team award at the inaugural CGIAR Inclusive Workplace Awards.
“When I see women achieving their dreams in science, or as businesswomen, and supporting other women, that keeps me hopeful,” said French Gates.

In the traditional Indian society Madhulika Singh grew up in, girls choosing to study science, technology, engineering or mathematics (STEM) was as radical as choosing a life partner on their own.
“They say women hold up half the sky. I believe they should hold up as much and contribute equally in STEM too,” says Singh, now an agriculture specialist at the International Maize and Wheat Improvement Center (CIMMYT).
In her early teens she saw her mother, a school headmaster, comfortably navigate her career along with her domestic responsibilities without a sweat. She later saw a similar example in her sister-in-law. “I grew up thinking ‘there is so much that a woman is capable of,’ whether at home or her workplace,” Singh recalls.
This strong idea of women’s potential led her to pursue studies in science. “Many women before me, like my mother’s generation, were encouraged to take up [careers in] humanities — become a teacher, or pursue home management courses — to ensure a smooth transition once married,” Singh explains. She hoped this would change during her time and that following a career in STEM would be a matter of choice — not gender.
Singh’s goals and ambitions were very clear from the very beginning. In school, she was interested in biology, particularly plant studies and botany. Her inquisitive nature was reflected in her projects and presentations, scoring her high grades. She demonstrated a thorough understanding of plant physiology and her passion for the subject. The budding scientist always wanted to know more and to do more, which Singh feels resonates with her current research and publications.
A popular quote attributed to Mahatma Gandhi says “Be the change you want to see in the world.” When Singh chose to take up plant science in graduate school and then agriculture science for her doctorate, she became the change she had hoped to see in her home and society as a young girl. With the support from her family but a skeptical society, she went ahead and pursued a career in STEM, beginning her research on maize genotypes and conservation agriculture. In 2013 she joined CIMMYT as a physiologist.

Helping farmers transition to conservation agriculture
Singh currently works in her home state of Bihar for the Cereal Systems Initiative for South Asia (CSISA), led by CIMMYT. She is engaged with over ten thousand farmers from the states of Bihar and Uttar Pradesh, supporting the adoption of conservation agriculture practices.
Farming is vital for the region, as nearly 70% of the population is engaged in agriculture and extension services. However, food and livelihoods are threatened by the small size of farms, low incomes, and comparatively low levels of agricultural mechanization, irrigation and productivity.
Singh and her colleagues have led the transition from traditional farming to sustainable intensification practices — like early wheat sowing, zero tillage and direct-seeded rice — which have helped smallholder farmers increase their yield potential substantially.
“We believe a project like CSISA, along with the government and partners, can help advance and support in realizing the full agriculture potential of these regions,” Singh explains.
Roots in the soil
Her grandparents were farmers. “To be able to care for the land that provided you nourishment and a living was always admired upon,” she says. As a crop scientist, Singh’s family acknowledges her work as an extension of the services her grandparents practiced.
Sustained by this motivation and encouragement, Singh feels reassured of her role: joining other scientists, partners and farmers to make agriculture sustainable and our communities food-secure.
“The fact that the data we generate from our experiments serve as building blocks in the generation of knowledge and help farmers optimize the cost of inputs and increase their productivity is fulfilling and enriching to me,” Singh expresses.
Apart from working to build the capacity of farmers and extension workers, Singh supports the implementation of field trials and community-based technology demonstrations. She also helps refine key agricultural innovations, through participatory testing, and optimizes cropping systems in the region.
Leading the way for for the next generation
A true representative of the STEM community, Singh is always learning and using her experience to give back to society. She has co-authored numerous books and contributed to journals, sharing her knowledge with others.
Other women leaders in STEM have inspired Singh in her professional life, including CIMMYT’s former deputy director general for research Marianne Banziger. Singh believes Banziger was trailblazing and that young girls today have many female role models in STEM that can serve as inspiration.
The change is already here and many more young women work in STEM, pursuing excellence in agriculture sciences, engineering and research studies contributing to as well as claiming “half the sky.”

Denise E. Costich, the recently retired head of the Maize Collection at the Germplasm Bank of the International Maize and Wheat Improvement Center (CIMMYT), sometimes likes to include a Woody Allen quote in her presentations.
“I have no idea what I’m doing,” declares the text over a photo of a befuddled-looking Allen. “But incompetence never stopped me from plunging in with enthusiasm.”
This is perhaps Costich’s tongue-in-cheek way of acknowledging the unusual trajectory that led her to the Germplasm Bank and her zeal for new and interesting challenges. But it is in no way an accurate reflection of the skill, knowledge and humane managerial style she brought to the job.
“CIMMYT requires individuals with a broad set of experiences,” says Tom Payne, head of the Wheat Collection at CIMMYT’s Germplasm Bank. Though she was not trained as a crop scientist, and despite having never worked in a genebank before, Costich’s rich set of professional and life experiences made her an ideal person for the job.
From Ithaca and back again
Born and raised in Westbury, NY, Costich spent much of her childhood on a tree nursery. Her grandfather was the manager, her father became the sales director and eventually her sister also went into the horticulture business. While her experiences on the nursery contributed to an early interest in plants and ecology, the business aspect of the nursery eluded her. “I just can’t sell things. I’m terrible,” Costich says. “But I really do like to study them.”
This studiousness took her to Cornell University in Ithaca, NY, where she initially declared as a wildlife biology major. Her notion of what it meant to “study things” was influenced by her early heroes, primatologists and field biologists Dian Fossey and Jane Goodall. It involved travel. Fieldwork in faraway places. So, when the opportunity arose at the end of her sophomore year to travel to Kenya with Friends World College, Costich didn’t hesitate.
Costich eventually spent four years in Kenya, studying baboons. When she finally returned to Ithaca, she knew two things. Fieldwork was absolutely her thing, and she wanted to pursue a doctorate.
A chance conversation with her housemates in her last semester led to a post-graduation fieldwork stint in the Brazilian Amazon under the supervision of the legendary tropical and conservation biologist, Thomas Lovejoy. But instead of a dissertation topic, she stumbled across a parasite, a case of leishmaniasis and the realization that the rainforest was not the work environment for her.
Unexpected influences and outcomes continued to mark Costich’s career throughout her graduate studies at the University of Iowa. She found her plant not in the field, but while reading a dusty review paper as an exchange student at the University of Wisconsin. Her study of Ecballium elaterium (a wild species in the Cucurbitaceae, or squash, family) did not take her back to the tropics — where most of her peers were working and where she expected to be headed as a grad student — but rather to Spain where, incidentally, she first learned Spanish.
Several years after defending, Costich landed a tenure-track position in the Biology Department at The College of New Jersey. She continued to publish on Ecballium elaterium. Her career appeared to be settling into a predictable, recognizable academic trajectory — one with no obvious intersection with CIMMYT.
Then Costich saw an ad in the Ecological Society of America bulletin for a managing editor position for all of the Society’s journals. Her husband, a fellow biology Ph.D., had been working as an academic journal editor for several years. When Costich saw the ad she immediately drove over to her husband’s office. “I slapped the thing on his desk and said, ‘Here’s your job!’” she recalls.
Costich was right. Soon after, she was on her way back to Ithaca — where the Society’s offices were located — with a family that now included three children. While it was the right move for her family, it came at the cost of her budding academic career. In Ithaca, she soon found herself stuck in the role of itinerant postdoc.

An amazing turn of events
Costich admits that, especially the beginning, the return to Ithaca was tough, even depressing. Her recollections of these years can sound a bit like a game of musical chairs played with research laboratories. As one post-doc or research project wound down, she’d find herself scanning the campus for her next perch. She became very adept at it. “In ten years, I never missed a paycheck,” Costich says.
The turn of the millennium found Costich scanning the horizon yet again. As the days wound down at her latest post, a maize geneticist moved into the lab next door. What started as hallway jokes about Costich jumping ship and joining the maize lab soon turned into an interview, then a job offer.
The job introduced her to nearly everyone at Cornell working in maize genetics. Costich soon found herself managing the Buckler Lab’s work on maize population genetics. Meanwhile, she dabbled in side projects on Tripsacum, a perennial grass genus that is closely related to maize, and managed a major project on switchgrass. At the end of her postdoc, Buckler set to work trying to create a permanent position for her. Once again, Costich’s trajectory was beginning to take a stable, predictable form.
Then CIMMYT scientist Sarah Hearne showed up. “I’d heard through the grapevine — or maybe through the corn field — that the position of manager of the Maize Collection of CIMMYT’s Germplasm Bank was open… and that they were having a hard time trying to find a person for the position,” Costich recalls. She had met Hearne previously and personally knew and had worked with Suketoshi Taba, the pioneering longtime director of the germplasm bank. Naturally the topic emerged as she and Hearne caught up in Ithaca.
Hearne admitted that the search hadn’t yet been successful. “But I know the perfect person for the job,” she added.
“Yeah, who’s that?” Costich asked, not getting the setup.

A stranger in a strangely familiar land
Costich was not a little surprised by the suggestion. She had never worked at a germplasm bank before. She was finally finding some stability at Cornell.
At the same time, her early dreams of exploring new places through her work, especially the tropics, beckoned. Her youngest son was nearly college-aged. Against the advice of some who had watched her work so hard to establish herself at Cornell, she took the plunge.
By the time she reached the CIMMYT campus in Texcoco, Costich had crisscrossed a good part of the globe, picking up Spanish here, management skills there, a deep knowledge of maize and its biological and cultural evolution yonder. During this life journey, she developed a deep humanism that is all her own.
It all seemed like happenstance, perhaps, until she reached Mexico and — suddenly, counterintuitively — found herself in the field she was perfectly adapted for. “It turned out that being a germplasm bank manager was the perfect job for me, and I didn’t even know it!” Costich says. “I ended up using everything I learned in my entire career.”
That isn’t to say that it was easy, especially at first. Taba, her predecessor, had occupied the post for decades, was a trained crop scientist, and had grown the bank from a regionally-focused collection with 12,000 accessions to the preeminent maize germplasm bank globally with 28,000 accessions, a state-of-the-art storage facility, and a slew of pioneering practices.
Not only had Taba left enormous shoes to fill, during his tenure — as is common in the expansionary phase of many projects — it had been difficult for the bank to keep a full accounting and understanding of all the new material that had been added. According to germplasm bank coordinator Cristian Zavala, by the time Costich joined CIMMYT “we knew very little about the material in our vaults.”
“Taba was primarily a breeder,” Costich says. “I actually think this oscillation between a focus on breeding and a focus on conservation and curation is good for the bank.”

A bank for farmers
However, according to Zavala, because of the limited knowledge of much material they were working with, many in the bank’s rank-and-file didn’t fully understand the importance of their work. Morale was mixed. Moreover, despite an assumption that her new job would see her working closely with local smallholders, Costich found that the institution was poorly known by everyday farmers in its host country. Where it was known, associate scientist on innovation and social inclusion, Carolina Camacho, notes, there was an assumption that CIMMYT only worked with hybrid varieties of maize and not the native landraces many smallholders in Mexico depend on.
These became the principal axes of Costich’s work at the bank: curation of backlogged material, staff development, and community outreach.
Thus, when Costich realized that records were being kept in a combination of paper and rudimentary digital formats, she sent Zavala, a promising young research assistant at the time, to an internship at the USDA’s Maize Germplasm Bank Collection in Ames, Iowa, to workshops at CGIAR germplasm banks in Colombia (CIAT) and Ethiopia (ILRI), and to meetings on specialized topics in Germany and Portugal.
Zavala had never left the country before, spoke little English, and remembers being “rebellious” at work. “I needed more responsibility,” he says. “Dr. Denise saw that and helped me grow.” Upon returning from an early trip, Zavala helped implement up-to-date traceability and data management processes, including migrating the genebank’s data onto the USDA’s GRIN-Global platform.
But as Payne points out, Costich’s tenure was never about simple bean — or, in this case, grain — counting. “She sees a more human aspect of the importance of the collections,” he says. The main tasks she set for the bank came to be subsumed into the overarching goal of a fuller understanding of the contents of the bank’s vaults, one that encompassed both their biological and sociocultural importance.
When Costich came across a collection of maize landraces from Morelos state assembled by Ángel Kato in the mid 1960s that conserved the name of the farmer who had donated each sample, she worked with Camacho and graduate student Denisse McLean-Rodriguez to design a study involving the donor families and their communities. McLean-Rodriguez, Camacho and Costich set out to compare the effects of ex-situ versus in-situ landrace conservation in both genetic and socioeconomic terms.
Similarly, when a colleague at INIFAP invited Costich to be a judge at a yearly contest for largest ear of Jala landrace maize in Mexico’s Nayarit state, they soon began discussing how they could contribute more than just their participation as judges to the community. Starting in 2016 Costich was a co-lead on a study of the landrace’s genetic diversity as well as an initiative to rematriate Jala seeds conserved at CIMMYT for over 60 years.

A genebank is not an island
Genebanks are bulwarks against genetic erosion. But, as Camacho explains, this mission can be understood in both very narrow and very broad senses. The narrow sense focuses on genetic processes per se: the loss of alleles. The broad sense includes the loss of cultural practices and knowledge built and sustained around the cultivation of a given landrace. Through the initiatives the bank has undertaken during her tenure, Costich has tried to demonstrate, both scientifically and in practice, how germplasm collections such as CIMMYT’s can complement, reinforce, and be enriched by the work of smallholders — de facto germplasm conservators in their own right — while contributing to the difficult task of combating genetic erosion in the broad sense.
One gets the sense that in Costich’s view this isn’t about a one-way process of big institutions “helping” smallholders. Rather it’s about collaboration among all the participants in an interdependent web of conservation. As she argued at her recent exit seminar, Costich views germplasm banks as one link in a chain of food security backups that begins at the farm level.
Indeed, Costich’s most recent initiative demonstrated how innovations intended for one link in the chain can travel upwards and find applications at bigger institutions.
Costich recently led an initiative with community seed banks in the Cuchumatanes mountain range of Guatemala to study the use of DryChain technology in post-harvest storage of maize. This experiment showed the enormous benefits that incorporating such technologies could yield for energy-insecure or low-tech family and community seed reserves.
Ultimately, however, the study led to a second experiment at CIMMYT’s tropical-climate station at Agua Fría in Mexico. With advice from collaborators at UC Davis and an industry partner (Dry Chain America), the seed conditioning team retrofitted an old drying cabinet at the station to dry maize without using heat, but rather by forcing air to circulate through sacks of drying beads. Under the direction of Filippo Guzzon, a postdoc and seed biologist working with Costich, the long-term viability of seeds dried using the accelerated technique versus traditional, slower techniques was tested. The study showed no loss in long-term viability using the accelerated drying technique.

A very busy retirement
At her exit seminar, Costich was presented a plaque in appreciation of her service at CIMMYT by Kevin Pixley, director of the genetic resources program. Terence Molnar, maize breeder with the Genetic Resources Team, has succeeded Costich as the Maize Germplasm Bank Head.
For some of her close colleagues, however, Costich’s departure is not the end of the road. “This is not a forever goodbye,” Guzzon says. “I will continue to be in touch with my cuatita,” says Camacho, who has also left CIMMYT.
For her part, Costich echoes that this is not a forever goodbye at all. Not to her friends and colleagues, and certainly not to her work. At a socially-distanced, maize-based farewell lunch Costich held just days before her departure, she was still busy weaving social connections and furthering collaborations among maize fanatics of all stripes — from chefs and designers to scientists and policy advocates.
She is already considering taking a part time position at her old lab at Cornell and a return to Tripsacum research. At the same time, she will be a visiting scientist at Mexico’s National Center for Genetic Resources (CNRG), where officially she will be heading up part of an international switchgrass study. Costich is hoping to leverage her tenure at CIMMYT by getting involved in a push to help improve the Mexican national system for plant genetic resources. Additionally, she has recently accepted an invitation from Seed Savers Exchange to join their board and she is looking forward to volunteering her time and expertise to various seed-saving initiatives within that organization and their many collaborators.
Asked what she’s looking forward to tackling in her retirement that isn’t work related, Costich betrays her deep allegiance to the plant world. “I don’t know,” she says, “I’m thinking of starting a big vegetable garden.”

The world is changing, and so is CGIAR. To achieve the Sustainable Development Goals by 2030, food systems — the way we grow, catch, transport, process, trade, and consume food — must be transformed, while meeting the challenges of climate change, and restoring the natural environment. The global pandemic further highlights the need for an integrated approach to food systems, and human, animal and environmental health.
In the face of these interdependent challenges, CGIAR, as the world’s largest public research network on food systems, is undergoing a dynamic transformation of its partnerships, knowledge, assets and global presence. Emerging as One CGIAR, it is sharpening its mission and impact focus to 2030, in line with the Sustainable Development Goals. CGIAR is integrating management, policies, and services; finding new, more impactful ways of doing research; sharing and investing more, pooled funding; and unifying its governance, including creation of the One CGIAR Common Board.
CGIAR’s Nominations Committee invites applications from qualified individuals to serve as members of the One CGIAR Common Board. The anticipated appointment date is September 1, 2020. Board members will be central to the transformation of CGIAR and its mission to deliver on global goals. The role presents opportunities to work with leaders across the CGIAR System, forging new linkages and partnerships in pursuit of an innovative, vital agenda.
CGIAR is a global research partnership for a food-secure future. CGIAR science is dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources and ecosystem services. Its research is carried out by 15 CGIAR Centers in close collaboration with hundreds of partners, including research institutes, civil society organizations, academia, development organizations and the private sector. www.cgiar.org
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.

“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.
