With courage, they are an example of innovation in the field

With its transversal focus on gender and social inclusion, CGIAR’s Latin American regional initiative AgriLac Resiliente shows how, through sustainable agriculture, women in the Latin American countryside are a fundamental piece to building resilient and inclusive food systems.

One of the most inspiring examples comes from the Tzotzil women’s group of TzabalĂł, in LarrĂĄinzar, Chiapas, Mexico. These women have found in the Chiapas Hub a platform that has allowed them to contribute significantly to the development of their households and environments.

“We are a group of women who have worked in pig and chicken farming for some years now. In 2022, we started working with CIMMYT and DAI (Desarrollo Alternativo e InvestigaciĂłn AC). We liked it a lot because we see that they are interested in women. They give us the opportunity to learn which awakens our interest in working in the field because we want to help our husbands, but with knowledge,” they said.

According to their testimonies, the opportunity to train in sustainable agriculture has been transformative. Previously, their participation in agricultural activities was limited. Now, with new knowledge acquired, they are producing healthy and nutritious food.

“If we just stay at home, we don’t do much, but when we go out to the countryside, we feel free, we clear ourselves of so many tasks around the house, and we bring tender beans and fresh vegetables. Now we can produce our food free of toxins and store our maize in airtight containers without chemicals,” they pointed out.

The experience has given them not only autonomy in making decisions about their food but also a sense of freedom and purpose when working in the field where the power of group work has also been a major factor in their success.

“It is always better to work in a group than individually, but it is necessary to find a good manager or leader to guide you and teach you how to work. As a group, we have obtained knowledge that we share among ourselves, we learned to prune fruit trees, we no longer burn stubble to recycle nutrients, there is more production and the product is bigger, and we also expect good fruit production.”

However, the path has not been without challenges. The community faces a sociopolitical context that makes collaboration between groups difficult, although these women persist and demonstrate with their achievements that female participation in agriculture is fundamental for community development.

“What we do, people see it badly and ask us why we go to the countryside to learn something that is not for us, that we leave because we don’t have chores at home, but we don’t get discouraged. When they see the results of the work, they ask us how we did it, and we tell them what we learned by not staying alone at home, and we invite them to join the group,” they mentioned, emphasizing that if you are in the group, it does not matter what political group you belong to because the only thing that matters is knowledge and the desire to improve oneself.

Their courage and determination have not only transformed their own lives but is also inspiring other women to join and follow this path of empowerment through sustainable agriculture.

These success stories are proof of the positive impact that the inclusion of women in the field can have. Their voice and experience are fundamental to building more resilient and sustainable food systems, where gender equity and the active participation of all actors are pillars for a prosperous future in rural areas of Latin America.

“It was a stunning experience for me to understand the operation of a hub and see farmers interact directly with field technicians, applying the principles of Conservation Agriculture. I remember a lady from Oaxaca telling us how productive she has become using la matraca, a simple, manual seeder and fertilizer,” says Mandla Nkomo during his recent visit to the Mixteca oaxaqueña in southern Mexico.

Mandla is the chief growth officer for the Excellence in Agronomy Initiative (EiA) which, “gathers more than 10 CGIAR Research Centers whose goal is to create solutions to problems that farmers face globally. EiA works on a foundation that is driven by demand to understand the challenges farmers are dealing with, and bring forth a development system for innovation that is capable of coping with those challenges and finding solutions that can be tested, validated, and scaled,” he mentions.

His searching for a system that triggers and diffuses innovation for farmers motivated Mandla to visit the hubs in Oaxaca, Mexico. “We are here because we wanted to study all the hubs and the projects based on the methods CIMMYT and its collaborators have developed in Mexico. One of the things we consider at EiA is the successful and sustainable transition from individual use to working within a partner network.”

“What we have seen here is the work of our colleagues from CIMMYT. For the last decade, they have come up with these hubs or innovation centers situated across different agroecological regions in Mexico. What is unique about the hubs is the ecosystem they are creating, which in my opinion, is what brings excellence in agronomy,” says Mandla.

The hubs are a management approach for innovation that was developed in Mexico based on initiatives like MasAgro-Cultivos para MĂ©xico. Due to its big impact, it’s being replicated in Asia, Africa, and in other Latin America countries. In addition, it lies in the heart of CGIAR initiatives.

About this methodology, Mandla says those who participate in it, are trying to understand the challenges that farmers truly face. Then a platform is developed to do proper research that responds to farmers’ needs. Subsequently, they test it in modules which provides proof of the impact these solutions are having as compared to conventional farming. Finally, these solutions are transferred to areas called extension, from which large-scale innovations are implemented.

During his visit to the research platform in Santo Domingo Yanhuitlan and to modules for innovation, extension areas, seed warehouses, post-harvest modules and machinery locations at different towns in Oaxaca, Mandla Nkomo and other visitors from EiA had the opportunity of learning not only how the South Pacific Hub operates but also witnessed how this management approach for innovation is socially and culturally relevant to one of the most diverse regions in the country.

“These days have been truly amazing. They have been very useful in refining the picture of what’s possible to do and scale. Mexico is a megadiverse country with varied agroecology. Our approach can be replicated in many parts of the world. I’m very excited with what we have seen. The country that gave us corn is now providing the world with solutions that will have major impacts on global food security. So, it is now our task (me and the whole EiA team) to find ways to pass this on to other latitudes”.

New High-Yield Corn Variety Boosts Agricultural Productivity in Peru

The introduction of the new high-yield corn variety, INIA 608 – ALLIMASARA, in Peru represents a significant collaboration between CIMMYT and the National Institute of Agricultural Innovation (INIA). This variety, developed through advanced crossbreeding techniques at the El Porvenir Agricultural Experimental Station, showcases CIMMYT’s pivotal role in enhancing agricultural productivity globally. By boosting yield capacities significantly up to 40% per hectare, this initiative not only supports the livelihoods of local farmers but also advances sustainable agricultural practices in challenging environmental conditions.

Responsible sourcing: how farmers, companies work together

CIMMYT challenges the idea that “win-win” partnerships require equals, proving smallholder farmers and large agri-food companies in Mexico can benefit mutually. Through sustainable sourcing, over 1.15 million tons of maize and wheat have been commercialized, benefiting both parties. Initiatives with companies like Bimbo, Heineken, and NestlĂ© enhance environmental sustainability while boosting farmers’ productivity. Led by Director General Bram Govaerts, CIMMYT pioneers sustainable farming, aligning with UN’s Sustainable Development Goals.

A sense of belonging: fostering gender equality and social inclusion in agricultural research

Efforts to improve gender equality and social inclusion are under the spotlight in many workplaces around the world. At CIMMYT, where values of Excellence, Integrity, and Teamwork guide the organization through its 2030 Strategy, commitment to shaping a more inclusive workplace is changing the face of scientific research.

In alignment with the CGIAR Gender, Diversity and Inclusion (GDI) Action Plan for 2023-2024 to achieve gender parity goals, CIMMYT has implemented multiple initiatives to make improvements across its workstreams and geographical locations.

“This is the start of a journey to harness and empower talent from across CIMMYT’s employee base,” said Director General, Bram Govaerts. “Starting with the actions outlined below, CIMMYT aims to become a leader in promoting gender equality and social inclusion in agricultural research and development.”

Empowering women

At CIMMYT, our commitment to gender equality is reflected in our global workforce. During the first half of 2023, women represented one in every three staff members. Across all roles, the current hiring rate for women is 43% in 2023 compared to 21% in 2020, with a particularly positive trend in regional offices, where the percentage has increased from 24% in 2021 to 43% in 2023. Annual improvements are also visible in the number of internationally recruited female staff, as 46% of these roles are filled by women in 2023, compared to 19% in 2022.

In our headquarters in Mexico, there is no major gender gap above 10%, even at the highest level, and 35-40% of employees are women. 50% of the members of the senior leadership team are women, with a significant number of women from diverse backgrounds forming part of our broader management structure. Progress is also visible in our regional offices. In Kenya and TĂŒrkiye, 43% and 40% of team members are women respectively, with both countries reaching the CGIAR target of 40/40/20 parity. For the first time, women represented at least 20% of employees in Bangladesh and Nepal in 2023.

However, we recognize there are still areas where CIMMYT must improve gender parity. While the overall gender balance continues to improve, the proportion of women working at CIMMYT globally rests at 32.5%, which is a statistic that can be increased. Gender gaps exceeding 10% can be observed in India and Nepal, where efforts are bridging gaps and forming environments where talent knows no gender.

Advancing equality by region

The impressive diversity of our workforce is one of our greatest strengths, and CIMMYT always seeks new ways to champion its people. As a global organization with presence in 88 countries, benefits are tailored to each region to target the specific needs of employees in each locality.

  • The creation of a Gratuity and Provident Trust Fund in Bangladesh, fostering gender equality by providing equal opportunities for financial stability and growth.
  • Standardized benefits in India, such as a uniform transport allowance and upgraded housing allowance that ensures fair financial benefits for all employees regardless of job grade.
  • Enhanced food coupons and savings funds for employees in Mexico, as well as an after-school program for the children of colleagues working at the headquarters.
  • Responding to economic challenges in Pakistan with a 20% general salary increase, a bonus of US $400, and the introduction of a gender-neutral transport allowance.
  • An increased allowance for children’s education in Zimbabwe.

In addition, Flexible Work Arrangements (FWA), parental leave, disability access improvements, and translation services showcase CIMMYT’s dedication to equality and inclusion.

Fulfilling careers for all

Investing in our people means ensuring that learning opportunities are equally accessible to all, empowering employees to reach their maximum capabilities. “We actively work to foster a culture and environment where all staff feel confident sharing their perspectives, their contributions are highly valued, and they see a path for growth within the organization,” said Deputy Director of Human Resources, Jean-Flavien Le Besque.

In 2023, 1,189 staff members participated in 431 training courses, with the number of participants increasing by nearly 23% in the same year. Additional e-learning opportunities available in both English and Spanish provide opportunities for professional development in health and safety, communications, personal efficiency, and critical thinking, all which aid staff with the development of valuable skills. These online courses supplement regular training on teamwork, hostile environment awareness, and diversity, equity, and inclusion.

The CIMMYT Academy also plays a significant role in training staff to be future leaders. In 2022, 52 students enrolled into the Academy; 52% of these students are women, underscoring CIMMYT’s commitment to developing everyone’s talent. Staff can also access a Tuition Grant scheme to pursue a higher-level degree.

Next steps

While these initiatives have strengthened gender equality and social inclusion at CIMMYT, further efforts are required to achieve true equity in all corners of the organization. These projects so far are just a glimpse into ongoing work to achieve the CGIAR GDI aims and will be built upon using employee feedback and specialist expertise.

“These successes are just the start of our pledge to ensure CIMMYT is inclusive and safe for all,” said Associate Scientist and Cropping Systems Agronomist, Mazvita Chiduwa. “We want to be an organization that is renowned not just for scientific excellence, but also for the way we champion all groups to reach the best of their ability, thrive in the workplace, and enjoy a positive work-life balance.”

Flowers, learning, and a gender-based approach

Gender and social inclusion are fundamental themes for the Latin American regional initiative AgriLac Resiliente, which is why numerous regions bordering Guatemala and Honduras have been selected to implement priority actions with a gender approach.

In order to integrate a guideline that clears up why gender and social inclusiveness are relevant matters and incorporate it in all InnovaHubs activities in Guatemala and Honduras, social inclusion and gender experts from AgriLac have implemented a participatory process in the South Pacific and Chiapas Hubs to gather information and document research results to facilitate the Hub model for replication, developed by CIMMYT in Mexico and other countries.

In this way, Alejandrina Garcia in Oaxaca, Alejandro Ramirez in Chiapas, and Angela Meentzan, head of the AgriLac Gender and Social Inclusion Team, conducted individual and group interviews to learn how the different actors involved in the hubs perceived their own participation: farmers, workers, managers, and staff of the hubs, as well as partners who participated in this participatory process.

There are numerous and successful cases of rural women’s participation in the centers of Oaxaca and Chiapas that have been collected in this process. “It is expected that these case studies will become part of an annex to the guideline, just to illustrate why the participation of rural women is essential in their own vision,” said Meentzen, who highlights the case of Juanita, a Tzeltal woman from La Providencia in Ocosingo, Chiapas, Mexico.

“About five years ago, I started working alongside CIMMYT. Before we knew them, we were only planting maize and beans, but then we couldn’t produce any more. The plants stopped growing, and we had a lot of problems with pests, so we used to burn all the stubble. When the engineers came, they invited us to join them. At first, we weren’t that interested, but we let them teach us. They taught us how to grow other crops like sunflowers, peanuts, vegetables, and fruit trees like lemon and soursop,” said Juanita.

“Now we don’t burn all the stubble and we have crops all year round. We also grow other types of plants and use a lot of organic products that they taught us how to prepare. Our production has increased, and we sell more and more at the market. My daughter and I take care of the sale of the crops: beans, corn, vegetables, squash, corn, and flowers; the latter have given us such good results that we have earned some extra money,” said Juanita.

“The benefits we got from our land allowed us to give our children a future. Some of them have graduated from college and have jobs; others are about to graduate, but they have all learned to work the land. It feels a little harder, but I have been able to take care of both: my family and the land. I don’t know how I did it, but I did it,” said Juanita proudly, noting that the scientific knowledge gained from the research platform and Hub modules has had a real and positive impact on her and her family.

In the eastern region of Honduras, Mirian Lizeth Torres, an agroindustrial engineer who graduated from the National Autonomous University of Honduras, is making a difference. Her commitment to agricultural sustainability and the empowerment of local communities through sustainable agriculture is evident in her work with the Eastern Regional Farmers Association (ARSAGRO, for its acronym in Spanish) and with her participation in the InnovaHub Oriente, set within the framework of the AgriLAC Resiliente initiative.

“In 2023, I volunteered at ARSAGRO, addressing crucial issues with producers, from events and extension to projects with CIAT that focused on the assessment of plots, water, soil, forest, pests and diseases, bean nutrition, grain quality, among others,” said Mirian, highlighting the breadth of her experience.

Her participation in the InnovaHub Oriente has been key to integrating theory and practice in the field. “I am a student of the conservation agriculture course, where I have explored agronomic practices that improve the sustainability of crops, creating more resilient systems,” she highlights. “These practices are shared with producers through innovation modules, which are plots where conservation agriculture innovations are implemented and compared, side by side, with conventional methods.”

Mirian knows the importance of communicating this knowledge to communities. “At events held on these plots, we shared practices and knowledge, reaching producers who were not familiar with these technologies,” she explains. “Thanks to AgriLAC, in 2023 we contributed significantly to the empowerment of producers and organized groups in eastern Honduras.”

Additionally, Mirian is proud of her role as an inspiration for the inclusion of youth and women in agriculture. “At every event we organize, we see increasing participation of young people and women,” she states. “The empowerment of women in agricultural activities has been notable, with many resuming activities in the field through the transfer of knowledge.”

Looking to the future, Mirian hopes to further encourage youth participation. “My invitation to young people is not to abandon the field; it is that they get involved in agricultural issues to contribute to the livelihood of their families and, at the same time, reduce migration,” she states with determination.

In a world where sustainable agriculture is essential, Mirian Lizeth Torres has assumed solid leadership from the field, helping her community move towards a more sustainable and equitable agricultural future.

Looking to the future, Mirian hopes to further encourage youth participation. “My invitation to young people is not to abandon the field, but rather that they get involved in agricultural issues to contribute to the livelihood of their families and, at the same time, reduce migration,” she states with determination.

Maria Itria Ibba presents award for research into improving nutrition in staple foods

Maria Itria Ibba, a scientist at CIMMYT, was among the presenters of the newly established Marie Clark Taylor CGF (Coalition for Grain Fiber) Fellowship. Katherine Frels presented the award to Delaware State University student Lauren A. Waller on 21 February at the Coalition for Grain Fiber workshop in Kansas City, KS. The fellowship is named after Marie Clark Taylor, an educator, plant breeder, and former dean at Howard University. It honors a minority student dedicated to applying plant science and/or food science for the benefit of all socioeconomic groups.

Lauren Waller, an undergraduate studying plant science, presented her research at the CGF workshop, Opportunities and Risks: Wheat Milling, Baking Supply Chain and the Coalition for Grain Fiber. The event’s theme was “creating the roadmap to growing more fiber – using commercial wheats to improve diets.”

“In the U.S., where dietary fiber is critical for cardiometabolic health, over 90% of women and 97% of men fall short of recommendations,” said Ibba. “Leveraging natural variation in wheat’s major fiber components offers a promising solution without disrupting current habits. By addressing these issues, we can bridge health gaps, recognizing the link between socioeconomic status and chronic conditions.”

The Coalition for Grain Fiber seeks to improve the nutrition in staple foods without negatively impacting their taste, feel, or consumer price. It is dedicated simultaneously to establishing profit incentives for farmers and other food suppliers that deliver foods with increased nutrients. “The efforts of the Coalition for Grain Fiber are pivotal in weaving a healthier future for all, breaking the chains of disease in under-served communities around the world.” The program builds research ties that allow students at HBCUs and minority-serving institutions to develop a network of mentors and collaborators at land grant- and R1 universities around the U.S.

Ibba joined Rod Wallace of the Foundation for Innovation in Healthy Food (FIHF) and Dr. Katherine Frels of the University of Nebraska-Lincoln in presenting the award.

In the ever-evolving field of agriculture, AGG-WHEAT is leading a transformative approach through rapid marker-selectable trait introgression in wheat breeding programs. This method aims to streamline the process of integrating desirable traits into various genetic backgrounds.

At the core of AGG-WHEAT’s strategy is the establishment of a centralized marker-selectable trait introgression pipeline. This initiative seeks to facilitate the transfer of specific genes from a centralized source into various genetic backgrounds within plant breeding programs. Molecular markers play a crucial role in efficiently identifying and selecting target traits.

The merits of a centralized trait introgression pipeline extend beyond convenience. This approach ensures a more uniform and controlled transfer of genetic material, enhancing the precision of trait introgressions across diverse breeding lines. Molecular markers streamline the selection process, improving the accuracy of desired trait incorporation into wheat varieties.

Speed breeding facilities in Toluca, Mexico

AGG-WHEAT’s marker-selectable trait introgression pipelines are implemented at the speed breeding facilities located at the CIMMYT research station in Toluca, Mexico. These facilities serve as the incubators for innovation, where new selection candidates are evaluated based on various criteria. The decision-making process involves an expert panel comprising geneticists, trait specialists, and breeders. This panel annually determines the selection candidates, considering factors such as trait demand, genetic diversity, evidence of Quantitative Trait Loci (QTL) effects, selection efficiency, and available funding.

The decision-making process involves a multifaceted evaluation of potential selection candidates. Documented trait pipelines and product profiles guide decision-making to ensure alignment with the overarching goals of wheat breeding programs. Considerations include the need for phenotypic variation and the existence of limited genetic diversity for the trait under consideration.

The decision-making process also explores existing in-house or external evidence of QTL effects and the underlying gene mechanisms. Selection efficiency, contingent on the availability of accurate molecular markers and a known purified donor parent, further refines the pool of potential candidates. Established phenotypic protocols for product testing and the crucial element of available funding complete the decision-making criteria.

Achievements

In a significant step towards innovation, the products of the first marker-selectable trait introgression pipelines entered yield trials in 2023. This marks a transition from conceptualization to tangible impact, reflecting the efficacy of AGG-WHEAT’s approach. A total of 97 F5-lines, cultivated through the marker-assisted backcross (MABC) scheme, now grace the fields.

These lines carry novel genes associated with fusarium head blight and rust resistance, derived from wheat genetic resources and wild relatives. The choice of these traits underscores AGG-WHEAT’s commitment to addressing challenges faced by wheat crops, ensuring improved resilience and sustainability in the face of evolving environmental conditions.

The success of these initial trait introgression pipelines represents more than a scientific achievement; it marks a pivotal moment in the trajectory of wheat breeding. The 97 F5-lines, standing as testaments to enhanced resistance traits, are poised to make a transition into mainstream breeding pipelines. This marks the commencement of a broader dissemination strategy, where these lines will be distributed for testing at National Agricultural Research and Extension Services (NARES).

The journey from the experimental fields to mainstream adoption involves a meticulous process. These lines, having undergone rigorous evaluation and selection, now hold the potential to catalyze changes in commercial wheat varieties. The lessons learned from their cultivation will shape future breeding strategies and contribute to the resilience of wheat crops in diverse agricultural landscapes.

AGG-WHEAT’s lasting impact

AGG-WHEAT’s marker-selectable trait introgression stands as an innovative approach in wheat breeding. The centralized approach, the strategic use of molecular markers, and the meticulous decision-making process exemplify the commitment to excellence and precision. The journey from concept to reality—marked by the entry of 97 F5-lines into yield trials—signals a new era in wheat breeding.

As these lines traverse from experimental fields to mainstream adoption, they carry the promise of transforming the landscape of commercial wheat varieties. AGG-WHEAT’s lasting impact goes beyond the scientific realm; it extends to the fields where farmers strive for sustainable and resilient wheat crops. In the tapestry of agricultural progress, AGG-WHEAT has woven a thread of innovation that holds the potential to redefine the future of wheat cultivation.

Enhancing wheat breeding efficiency in South Asia through early germplasm access

In the dynamic landscape of wheat breeding, early access to germplasm emerges as a strategic catalyst for accelerating variety turnover and meeting the evolving challenges faced by farmers in South Asia. Since its inception, the Accelerating Genetic Gains in Maize and Wheat (AGG) project has pioneered new tools to optimize the wheat breeding process. One such tool, the efficient and low-cost 3-year breeding cycle, has been fine-tuned in Mexico, using the Toluca screenhouse and field advancement in ObregĂłn, laying the groundwork for faster variety turnover.

The inaugural set of lines generated through this enhanced breeding cycle is already undergoing Stage 1 trials in the ObregĂłn 2023-24 season. However, the innovation doesn’t stop there; to expedite the variety release process and garner robust data from the Target Population of Environments (TPE), Stage 2 lines are being rigorously tested at over 20 sites in South Asia through collaboration with National Agricultural Research and Extension Services (NARES) partners. In the seasons spanning 2021-2024, a total of 918 Stage 2 lines underwent rigorous trials, aiming to provide early access to improved wheat lines for testing and release by NARES and establish a genetic correlation matrix between ObregĂłn selection environments and diverse sites across South Asia.

These extensive trials serve a dual purpose. Firstly, they facilitate early access to improved wheat lines for testing and release by NARES, bolstering the agricultural landscape with resilient and high-yielding varieties. Secondly, they contribute to the establishment of a genetic correlation matrix between the selection environments in ObregĂłn and the diverse sites across South Asia. This matrix becomes a guiding compass, aiding in selecting the most promising lines for broader TPEs in South Asia and beyond.

Transformative impact on wheat varieties in South Asia

Through the support of our partners and funders from the Bill & Melinda Gates Foundation, the Foundation for Food and Agriculture Research (FFAR), the UK Foreign, Commonwealth & Development Office (FCDO), and the US Agency for International Development (USAID), great achievements have been recorded throughout the region. India, a prominent player in wheat cultivation, stands as a testament to the transformative impact of early access to advanced lines. The top three varieties, namely DBW187, DBW303, and DBW 222, covering over 6 million hectares, trace their roots to CIMMYT varieties. Adopting a fast-track approach through early-stage testing of these advanced lines at BISA sites in India, supported by the Delivering Genetic Gain in Wheat (DGGW) project, facilitated the release of these varieties two years ahead of the regular testing process. This expedited varietal release was complemented by the innovative early seed multiplication and dissemination approach introduced by the Indian Council of Agricultural Research (ICAR). Recent additions to this accelerated channel include varieties such as DBW 327, DBW 332, DBW 370, and 371, promising further advancements in wheat cultivation.

In Pakistan, the early access to advanced lines has been a catalyst for releasing high-yielding, climate-resilient, and nutritious wheat varieties. In 2023 alone, 12 new varieties were released, with the renowned ‘Akbar-19,’ introduced in 2019, covering a substantial 42% of cultivated land in Punjab. Data released by the Ayub Agricultural Research Institute (AARI), shows that this variety, known for its high yield potential, disease resistance, and enriched zinc content, has significantly contributed to increased wheat production in the region.

Guided by policy interventions in the national varietal testing process, Nepal has experienced the fast-track commercialization of high-yielding and climate-resilient wheat varieties. Allowing multilocation testing of CIMMYT nurseries and advanced elite lines, Nepal released six biofortified zinc wheat varieties in 2020. The expeditious seed multiplication of these released and pre-release varieties has facilitated the rapid spread of new and improved wheat varieties.

The strategic utilization of early access to wheat germplasm in South Asia holds promise in accelerating variety turnover, offering farmers resilient and high-performing wheat varieties. Collaborative efforts between research institutions, government bodies, and international organizations exemplify the power of innovation in transforming agriculture. With an ongoing dedication to refining breeding cycles, expanding testing initiatives, and fostering collaboration, the AGG project contributes to building a sustainable and resilient agricultural future in South Asia. Early access to wheat germplasm emerges as a practical approach in this scientific endeavor, laying the foundation for a climate-resilient and food-secure region. The successes witnessed in India, Pakistan, and Nepal underscore the transformative potential of this approach, offering tangible benefits for agricultural communities in South Asia and beyond. In navigating the complexities of a changing climate and growing food demand, early access to wheat germplasm remains a pragmatic ally, propelling agricultural innovation and resilience to new heights.

STEM the gap: Scientists reflect on women’s increasing participation and visibility in STEM careers

Much has changed since many CIMMYT scientists attended university. In the past decades, the STEM field was predominantly male, with far less representation from marginalized groups and communities. Challenged by societal prejudices, only a handful of young women pursued STEM subjects, which further influenced career choices made by them, reinforcing the gender gap.

The gender gap in STEM is still significant, but times are changing. “At CIMMYT, we are deeply committed to promoting the voice of youth, marginalized communities, and women to improve the rigor of science for sustainable development. This includes investment in mentorship, learning from champions and pioneers, and appropriate performance assessment guidelines,” said Program Director of CIMMYT’s Sustainable Agrifood Systems, Sieglinde Snapp. “It is a long journey with bumps along the way, but I am proud to be in solidarity with the Global South, where we champion gender and social inclusion every day.”

On International Day of Women and Girls in Science 2024, five CIMMYT scientists who inspire, support, and open doors for many young women and underrepresented groups with their scientific work and pay-it-forward commitment share their motivation behind charting a career in STEM and encourage more young women and make the field more inclusive.

Hailing from a farming family, Beyhan Akin was always surrounded by the beauty and potential of agriculture. She wished to contribute to her farming community, so 35 years ago, she joined CIMMYT’s wheat research program. Akin reminisced about her early days, how there were few women scientists, and the realization that if she succeeded, she could motivate more to follow in her footsteps.

“Agriculture science is expanding beyond core crop science with huge potential for interdisciplinary research and innovation. I hope young women students and scientists get the opportunity to pursue and excel in these fields. Increased advocacy and investment—grants, fellowships—at an institutional level is crucial to motivating and supporting the aspirations of women in science,” said Akin. “It might have taken a long time for women scientists like us to be in positions of influence, but I hope we can ensure the path is far less challenging today for these young women pursuing agriculture science/STEM.”

“Search out mentors. Don’t be afraid to either ask for help when you need it or to promote your achievements. And build networks,” advises Alison Laing to young women scientists starting in the field. Based in Bangladesh and working across South and Southeast Asia for over 15 years, Laing hopes that girls have opportunities to choose science education and become women with rewarding careers in fields that interest them, especially in non-traditional STEM disciplines.

Laing remembers how her mentor early in her career, the late John Schiller, a rice agronomist at the International Rice Research Institute (IRRI), encouraged her enthusiasm for learning and research. “He taught me so much about doing research in Southeast Asia, and I am indebted to him for his motivation and support in showing me how rewarding and interesting a scientific career can be.” She hopes other young students and scientists will have such mentors in their lives.

Fascinated by nature, plants, and how they thrive in diverse environments, Sabina Tiwari’s journey in science led her to become a plant breeder. “The indefinite potential of agriculture to improve lives made me realize how powerful agricultural science can be. This led to the motivation that I could create a positive difference in the world by being part of crop science and technology while working alongside great scientific minds, both men and women. Today, to young girls aspiring to make a difference in the world, I recommend they empower their cause through science and innovations.”

According to Tiwari, mentorship programs, internships, and job-shadowing experiences that helped her career must be extended to young women to gain practical exposure and knowledge of the possibilities in agriculture science.

For Mazvita Chiduwa, a career in agriculture science has been rewarding. “I love the adventure involved in discovery in agriculture. I am inquisitive, and this career allows me to ask questions and seek answers,” said Mazvita.

Chiduwa believes society needs to embrace the participation of women and girls in STEM education and careers and that stereotypes about women not being cut out for STEM, prevalent even today, must be done away with.

To young girls and women aspiring for a career in STEM, Chiduwa says, “Go for it. There is a need for your uniqueness to contribute a wholesome solution to our world’s challenges.”

“A feminine perspective and approach are needed to enrich research,” reminds Luisa Cabrera Soto. “In a society where almost half of the members are female, I hope equity and inclusion will help improve under-representation in STEM.”

According to Cabrera, it is essential that women in science continue to challenge the gender prejudices and stereotypes that still exist. “Don’t let the spark of your curiosity go out. As a food science professional, I can say that there are still discoveries to be made and, through it, the probability of finding innovative solutions to global challenges such as food security.”

Wheat blast spread globally under climate change modeled for the first time

Climate change poses a threat to yields and food security worldwide, with plant diseases as one of the main risks. An international team of researchers, surrounding professor Senthold Asseng from the Technical University of Munich (TUM), has now shown that further spread of the fungal disease wheat blast could reduce global wheat production by 13% until 2050. The result is dramatic for global food security.

With a global cultivation area of 222 million hectares and a harvest volume of 779 million tons, wheat is an essential food crop. Like all plant species, it is also struggling with diseases that are spreading more rapidly compared to a few years ago because of climate change. One of these is wheat blast. In warm and humid regions, the fungus magnaporthe oryzae has become a serious threat to wheat production since it was first observed in 1985. It initially spread from Brazil to neighboring countries. The first cases outside of South America occurred in Bangladesh in 2016 and in Zambia in 2018. Researchers from Germany, Mexico, Bangladesh, the United States, and Brazil have now modeled for the first time how wheat blast will spread in the future.

Regionally up to 75% of total wheat acreage affected

According to the researchers, South America, southern Africa, and Asia will be the regions most affected by the future spread of the disease. Up to 75% of the area under wheat cultivation in Africa and South America could be at risk in the future. According to the predictions, wheat blast will also continue to spread in countries that were previously only slightly impacted, including Argentina, Zambia, and Bangladesh. The fungus is also penetrating countries that were previously untouched. These include Uruguay, Central America, the southeastern US, East Africa, India, and eastern Australia. According to the model, the risk is low in Europe and East Asia—with the exception of Italy, southern France, Spain, and the warm and humid regions of southeast China. Conversely, where climate change leads to drier conditions with more frequent periods of heat above 35 °C, the risk of wheat blast may also decrease. However, in these cases, heat stress decreases the yield potential.

Dramatic yield losses call for adapted management

The affected regions are among the areas most severely impacted by the direct consequences of climate change. Food insecurity is already a significant challenge in these areas and the demand for wheat continues to rise, especially in urban areas. In many regions, farmers will have to switch to more robust crops to avoid crop failures and financial losses. In the midwest of Brazil, for example, wheat is increasingly being replaced by maize. Another important strategy against future yield losses is breeding resistant wheat varieties. CIMMYT in collaboration with NARs partners have released several wheat blast-resistant varieties which have been helpful in mitigating the effect of wheat blast. With the right sowing date, wheat blast-promoting conditions can be avoided during the ear emergence phase. Combined with other measures, this has proven to be successful. In more specific terms, this means avoiding early sowing in central Brazil and late sowing in Bangladesh.

First study on yield losses due to wheat blast

Previous studies on yield changes due to climate change mainly considered the direct effects of climate change such as rising temperatures, changing precipitation patterns, and increased CO2 emissions in the atmosphere. Studies on fungal diseases have so far ignored wheat blast. For their study, the researchers focused on the influence of wheat blast on production by combining a simulation model for wheat growth and yield with a newly developed wheat blast model. Environmental conditions such as the weather are thus included in the calculations, as is data on plant growth. In this way, the scientists are modeling the disease pressure in the particularly sensitive phase when the ear matures. The study focused on the influence of wheat blast on production. Other consequences of climate change could further reduce yields.

Examining how insects spread toxic fungi

According to the World Health Organization (WHO), 10% of the global population suffers from food poisoning each year. Aflatoxins, the main contributor to food poisoning around the world, contaminate cereals and nuts and humans, especially vulnerable groups like the young, elderly, or immune-compromised, and animals are susceptible to their toxic and potentially carcinogenic effects.

Fungi contamination occurs all along the production cycle, during and after harvest, so the mitigation of the mycotoxins challenge requires the use of an integrated approach, including the selection of farmer-preferred tolerant varieties, implementing good agricultural practices such as crop rotation or nitrogen management, reducing crop stress, managing pests and diseases, biological control of mycotoxigenic strains, and good post-harvest practices.

Monitoring of mycotoxins in food crops is important to identify places and sources of infestations as well as implementing effective agricultural practices and other corrective measures that can prevent outbreaks.

A bug problem

Insects can directly or indirectly contribute to the spread of fungi and the subsequent production of mycotoxins. Many insects associated with maize plants before and after harvest act as a vector by carrying fungal spores from one location to another.

International collaboration is key to managing the risks associated with the spread of invasive pests and preventing crop damage caused by the newly introduced pests. CIMMYT, through CGIAR’s Plant Health initiative, partners with the Center for Grain and Animal Health Research of the US Department of Agriculture (USDA) and Kansas State University are investigating the microbes associated with the maize weevil and the larger grain borer.

The experiment consisted of trapping insects in three different habitats, a prairie near CIMMYT facilities in El Batán, Texcoco, Mexico, a maize field, and a maize store at CIMMYT’s experimental station at El Batán, using Lindgren funnel traps and pheromones lures.

Preliminary results of this study were presented by Hannah Quellhorst from the Department of Entomology at Kansas State University during an online seminar hosted by CIMMYT.

The collected insect samples were cultured in agar to identify the microbial community associated with them. Two invasive pests, the larger grain bore and the maize weevil, a potent carcinogenic mycotoxin was identified and associated with the larger grain borer and the maize weevil.

The larger grain borer is an invasive pest, which can cause extensive damage and even bore through packaging materials, including plastics. It is native to Mexico and Central America but was introduced in Africa and has spread to tropical and subtropical regions around the world. Together with the maize weevil, post-harvest losses of up to 60% have been recorded in Mexico from these pests.

“With climate change and global warming, there are risks of these pests shifting their habitats to areas where they are not currently present like sub-Saharan Africa and North Africa,” said Quelhorst. “However, the monitoring of the movement of these pests at an international level is lacking and the microbial communities moving with these post-harvest insects are not well investigated.”
