His legacy, driven by CIMMYT in collaboration with the Government of Mexico, has had a profound and lasting impact on global food security. This legacy has inspired and empowered the role of numerous women in agricultural science, encouraging them to lead innovative and essential research to address global food challenges.

Among the women who have stood out due to this influence is Evangelina Villegas, a Mexican scientist whose pioneering work in nutritional maize improvement had a global impact. Together with Dr. Surinder Vasal, Villegas developed quality protein maize (QPM), an innovation that significantly reduced malnutrition and improved nutritional quality for millions of people in developing countries. For these contributions, Evangelina Villegas was awarded the World Food Prize in 2000, becoming the first woman to receive this prestigious honor.

Beyond her scientific achievements, Evangelina Villegas stood out for her commitment to mentoring new generations of researchers, especially women. Her efforts opened doors for more women scientists to participate in high-impact social projects, establishing her as a role model for female leadership in agricultural science.

Villegas’s career clearly reflects the continuation of the social and scientific commitment initiated by Borlaug. Her example highlights how his legacy has not only positively influenced science but also played a crucial role in advancing gender equity within the agricultural and scientific sectors.

How Crops to End Hunger is transforming CGIAR crop breeding from the ground up

Written by dmedina on May 22, 2025. Posted in Blogs.

When crop breeding succeeds, the impact is dramatic: improved varieties reach farmers, productivity increases, and resilience to climate change and disease improves. But breeding success doesn’t happen by chance. It relies on modern facilities, cutting-edge tools, and the ability to test and select for complex, evolving traits. That’s where Crops to End Hunger (CtEH) comes in. At CGIAR Science Week, the project team and beneficiaries demonstrated how.

A project designed for exponential impact

Launched in 2019, CtEH aimed to support the modernization of CGIAR’s crop breeding infrastructure, with support from GIZ, the Gates Foundation, the US government, DFID, and ACIAR. As it nears the end of the most recent two-year GIZ funding cycle, the project has made targeted investments in upgrading breeding station infrastructure, equipping them with advanced tools, building capacity across CGIAR and national breeding teams, and developing the foundational systems needed to accelerate the entire breeding process.

Supporting CGIAR Centers’ core functions

At CGIAR Science Week, Bram Govaerts, CIMMYT Director General, explained: “CtEH is crucial for implementing CIMMYT 2030 strategy. Support has increased our breeding capacity for maize, wheat, and newly added dryland crops that complement maize and wheat cropping systems.”

One example is the Groundnut Biotic Stress Screening Network, established with CtEH support. The network has strengthened the capacity of partners in Uganda and Malawi to screen for groundnut rosette disease; a devastating disease spread by aphids can result in 100% crop loss, with annual losses of over $150 million. The screening network will enable development of resistant varieties.

In Kenya, a $2.5 million worth infrastructure upgrade at the KALRO–CIMMYT Crop Research Facility in Kiboko, has accelerated breeding cycles. This investment is enabling the development of new varieties tailored to the needs of East African farmers. Drought-tolerant maize varieties developed through work in Kenya and Zimbabwe have expanded dramatically, from just 0.5 million hectares in 2010 to 8.5 million hectares across sub-Saharan Africa today.

The Kiboko station is also a regional leader in pest and disease resistance. Its advanced screening capabilities for fall armyworm have led to the release of three tolerant maize hybrids, benefiting farmers in Kenya, Malawi, Zambia, Zimbabwe, South Sudan, and Ghana. The development of maize varieties resistant to maize lethal necrosis further demonstrates the station’s critical role in enhancing food security across the region.

Operational improvements: more than bricks and mortar

CtEH isn’t just about infrastructure; it’s also about operational transformation which profoundly change the breeding work. For instance, as Gustavo Teixeira explains, “The installation of reliable irrigation systems, one of CtEH’s key priorities, improves breeding efficiency in several ways. It enables off-season trials, allowing breeders to conduct multiple generations per year. It promotes plot control, ensuring uniformity across trial plots and data quality. Finally, it improves the ability to breed for drought tolerance.”

In Ghana, Maxwell Asante of CSIR-CRI described how CtEH brought crop-neutral upgrades that have encouraged teams to strategically plan and align resources, enabled cost attribution to specific breeding programs, improving accountability, and fostered cross-location collaboration by making centralized services possible.

These operational improvements are helping CGIAR and national systems move toward truly modern breeding programs that can operate with greater precision, speed, and coordination.

Building for regional collaboration and innovation

Bram Govaerts also emphasized that collaboration is central to the future of breeding, and that CtEH is helping to make that possible.

“Strategic collaborations enhance our impact by leveraging diverse resources and expertise, especially through public-private partnerships that scale research and technology transfer for agricultural transformation.”

Facilities and systems funded by CtEH are helping CGIAR foster cross-disciplinary innovation and strengthen ties with governments, donors, and technology companies. This makes it easier to bridge the gap between research and real-world application – exactly what’s needed to accelerate impact.

Empowering women in breeding

Infrastructure improvements under CtEH have considered inclusivity and gender equity.

Aparna Das, CIMMYT Technical Lead, explained that modernized stations have been upgraded to better support women in breeding roles – such as providing restrooms and expression rooms in remote research stations, often located far from urban centers, which help attract talent.

Why does this matter? Women breeders bring valuable perspectives, particularly in identifying gender-relevant traits, like cooking time, seed size, and ease of harvesting. Diverse, balanced breeding teams also tend to be more dynamic and innovative, leading to better science and more relevant products for farmers.

Targeting the right traits

Breeding for traits farmers need starts with the ability to test and measure those traits under real-world conditions. This can require specialized equipment.

Maxwell Asante emphasized that this is where CtEH makes a difference:

“Testing for traits is fundamental. And now, we’re not just selecting for yield – we’re breeding for disease resistance, climate resilience, cooking quality, and more. The only way to do this efficiently is through modern breeding infrastructure and processes.”

Modern breeding enables scientists to combine multiple traits in a single variety and identify the best candidates with greater accuracy and confidence. This is made possible through CtEH investments in equipment and data analytics, such as Bioflow, the CtEH-funded breeding analytics pipeline developed for CGIAR and its partners.

Long-term impact through smart design

What makes CtEH unique is its sustainability-by-design approach. The project was structured to build long-lasting capacity and to leverage investments from across CGIAR Initiatives, amplifying both the quality of upgrades and their outcomes.

Whether it’s enabling year-round trials, supporting new partnerships, or empowering a more diverse generation of breeders, CtEH is not just upgrading infrastructure, it’s also reshaping CGIAR and partners’ breeding.

As CGIAR continues to respond to climate, nutrition, and food security challenges, projects like CtEH are making sure we have the tools, systems, and people in place to breed for tomorrow – starting today.

New Breakthrough in Wheat Blast Resistance: A Novel Non-2NS QTL Identified

Written by dmedina on May 15, 2025. Posted in Blogs.

A newly published study has identified a significant breakthrough in the ongoing battle against wheat blast: a novel quantitative trait locus (QTL), named Qwb.cim-7D, located on the long arm of chromosome 7D and derived from Aegilops tauschii, offers stable and moderate resistance to wheat blast—independently of the widely used 2NS translocation.

Wheat blast, caused by Magnaporthe oryzae pathotype Triticum (MoT), is a rapidly spreading disease threatening wheat production, particularly in tropical and subtropical regions of the world. First detected in Brazil in 1985, the disease has since caused devastating yield losses—up to 100% in severe cases. Its transboundary spread, including recent incursions in Bangladesh and Zambia, has intensified international concerns about food security, especially among vulnerable smallholder farming communities. Control through chemical means has proven unreliable, placing even greater emphasis on the development and deployment of resistant wheat cultivars.

Fig. 1 Global incidence of wheat blast with years of its first identification indicated for the affected countries

For years, wheat breeders have relied on a single major source of genetic resistance—the 2NS/2AS translocation from Aegilops ventricosa. While initially effective, recent field observations—particularly in Brazil—suggest that wheat blast pathogens are evolving to overcome this resistance. Despite extensive efforts, previous studies have failed to identify any non-2NS QTLs with both significant and stable effects across environments in field trials.

A New Genetic Solution for Blast Resistance

In a recently published study entitled “A novel QTL on chromosome 7D derived from Aegilops tauschii confers moderate field resistance to wheat blast”, CIMMYT’s wheat pathology team and collaborators reported the identification of a novel and consistent QTL—Qwb.cim-7D—which provides significant resistance to wheat blast independent of the 2NS translocation.

The donor bread wheat line, Gladius*2/KU 2097, inherited its resistance from the resistant Ae. tauschii accession ‘KU-2097’. Field experiments were conducted at two Precision Phenotyping Platforms (PPP) in Bolivia (Quirusillas and Okinawa) and one PPP in Bangladesh (Jashore), under artificially inoculated conditions—ensuring a robust evaluation of resistance. The QTL was mapped to the long arm of chromosome 7D, where it explained between 7.7% and 50.6% of the phenotypic variation across different environments. This is a significant finding, as previous studies identified non-2NS resistance loci with typically small effects (less than 10%) and inconsistent performance. In contrast, Qwb.cim-7D is the first moderate-effect QTL to demonstrate stable resistance across multiple field conditions.

To facilitate its adoption in breeding pipelines, researchers successfully converted the flanking DArTseq markers into KASP markers—enabling more efficient marker-assisted selection.

Importantly, Qwb.cim-7D provides approximately half the resistance effect of 2NS, highlighting its value as a complementary resistance factor. When deployed through gene pyramiding strategies alongside 2NS and Rmg8, this new QTL could help breeders develop varieties with stronger and more durable resistance to the evolving wheat blast pathogen.

This breakthrough marks a turning point in global wheat blast resistance breeding. It addresses the urgent need to diversify the genetic basis of resistance and equips breeders with a viable new tool to safeguard wheat yields. As wheat blast continues to threaten food security in key regions, the introgression of Qwb.cim-7D into breeding programs offers a promising path toward enhanced crop resilience and improved farmer protection.

Shaping a CIMMYT maize program to serve at-risk farmers: A tribute to Ernest W. Sprague (1925-2025)

Written by Mike Listman on April 15, 2025. Posted in News.

Photo caption: Ernest W. Sprague, director of CIMMYT’s maize program during 1970-1983 (Photo: CIMMYT)

Architect of CIMMYT maize research during the 1970s, Ernest W. Sprague pulled together a coherent global program from diverse regional and country initiatives in Latin America, Asia, and eastern Africa, building partnerships with national maize research programs to serve smallholder farmers.

On 25 February, Ernest W. Sprague, who served as Maize Program Director at CIMMYT from 1970 to 1983, passed away at the age of 100.

Sprague led the development and adoption of systematic approaches for breeding improved maize populations adapted to the tropics and subtropics, including the international testing of varieties and crosses at scale.

After leading the Inter-Asian Corn Program established by the Rockefeller Foundation in Thailand in 1966, Sprague joined CIMMYT, where he vigorously championed the role of open-pollinated maize varieties (OPVs) for smallholder farmers in rain-fed maize cropping areas. These farmers often faced diseases, pests, and drought and lacked access to or could not afford hybrid seed or large quantities of fertilizer.

OPVs generally yield less grain than maize hybrids but are often preferred by smallholders for their suitability in local foods. They can also be grown by saving and sowing seed from previous harvests without sacrificing yield or other qualities—a problem that arises when grain harvested from hybrids is replanted.

In Thailand, Sprague had witnessed a thriving maize sector powered by the widespread adoption of an improved OPV known as “Suwan 1.” Conversely, he believed that hybrid seed systems designed to serve small-scale farmers were lagging in many other countries where CIMMYT worked.

“From the late 1980s, CIMMYT has worked successfully to develop and share hundreds of maize inbred lines—parents for high-yielding hybrids that feature farmer-preferred traits—as well as supporting and partnering with competitive private seed sector companies that truly benefit smallholder maize farmers,” said Bram Govaerts, CIMMYT Director General. “Still, population improvement in the OPV breeding program under Sprague’s leadership clearly contributed to the success of CIMMYT’s hybrid research by increasing the average performance of lines extracted from those populations.”

In addition, much of CIMMYT’s research on hybrid breeding for tropical maize in the 1980s and 1990s was led by Surinder K. Vasal, an Indian maize scientist brought to CIMMYT by Sprague.

Vasal’s pre-biotech research, together with CIMMYT cereal chemist Evangelina Villegas, led to the development of quality protein maize (QPM), whose grain contains enhanced levels of two amino acids essential for human protein synthesis. This groundbreaking work—initiated by Sprague—was recognized with their joint reception of the 2000 World Food Prize.

Building up partners and partnerships

Sprague was a strong proponent of in-service training at CIMMYT headquarters in Mexico for young researchers from partner countries. These courses were formally organized and scaled up in the early 1970s as a major component of CIMMYT’s maize program. Participants worked for several months within the main breeding or production programs, usually in the lowland tropics of Mexico, gaining hands-on skills in the field through activities such as laying out on-farm trials, selecting germplasm, making crosses, and evaluating results. By 1982, the program had graduated 650 maize scientists from 61 countries. Many alumni rose to influential positions in national programs or the private sector, thereby strengthening regional cooperative maize research networks.

“Ernie was my boss when I first arrived as a postdoc to CIMMYT in 1976, and I was always amazed at his commitment to high-quality field work,” said Greg Edmeades, a maize physiologist whose research accomplishments included methods to select for drought tolerance in maize. “I will always remember Ernie as a friend and a great supporter of the task we faced in Ghana, where I worked as a maize agronomist and lived with my family during 1979–84. He thought often of the challenges that we as a family faced with frequent water and power cuts and generously provided support. I was always amazed at his stamina and his capacity to survive and keep fit and well on black coffee alone in the mornings and no major meal until evening.

“Sprague’s contributions to CIMMYT were significant. The setting up of the international testing system was his baby and a masterpiece in getting CIMMYT germplasm out to national programs. He elevated the status of national programs in all sorts of ways, not the least of which was training.”

The CIMMYT global community joins in remembering Ernie Sprague and extends heartfelt condolences to his family.

Munich Statement on Agriculture, Biodiversity and Security: there is no security without food security

Written by dmedina on April 7, 2025. Posted in News.

In February 2025, leading voices in the global food and agricultural system came together on the occasion of the Munich Security Conference to discuss how to achieve food security in an increasingly insecure world.

Biological diversity is key to food and nutritional security, but all too often neglected. The loss of agricultural biodiversity (which includes crop diversity) threatens not just the resilience of global food systems but also their productivity. This in turn undermines rural livelihoods and economic activity, increasing the likelihood of migration. It also heightens the risk of price spikes and restricts the availability of staple food products, which may hamper trade in important commodities as governments seek to shore up sufficient stockpiles for domestic markets.

Compromised food systems and agricultural biodiversity loss destabilize and damage communities, potentially to an existential level, while preserving agricultural biodiversity and investing in resilient farms are the foundations for peace and prosperity. Stakeholders across the international community, including the security community, civilian agencies, civil society and businesses, should act to preserve and use agricultural biodiversity and promote sustainable agriculture by putting farmers first.

As the ultimate providers of life-sustaining nutrition, farmers are indispensable global security partners. Farmers provide a steadying economic force, but only if they have adequate safety, and access to land, investment, innovation, and functioning markets. It is imperative to provide farmers with the support, investment, and opportunities for innovation to adapt to changing global environmental conditions and persevere through social unrest and conflict. Farmers must be able to employ agricultural practices that concurrently promote nutrition, water security, human health, and biodiversity preservation. Prioritizing the delivery of nutrient-rich foods and bio-based products in ways that respond to water and weather stress is essential.

Crucially, for farmers to be successful, they need continued access to agricultural biodiversity. To ensure that, genebanks must be seen as a shared strategic strength.

Reliable, sufficient, and nutritious food for the current and future population depends on the crop diversity that underpins critical research and breeding efforts. Despite its increasing importance in light of a changing climate, the conservation and availability of crop diversity is increasingly at risk: it is declining in farmers’ fields and in the wild, and genebanks are chronically underfunded. Growing food demands, land degradation, and geopolitical tensions threaten crop diversity, and more generally agricultural economies.

Given their essential role in food security, genebanks should be strategically protected and funded. Sufficient attention and resources should be available to ensure an effective and efficient global system of genebanks under the policy umbrella of the International Treaty on Plant Genetic Resources for Food and Agriculture. In addition, the security community should incorporate food security and agricultural biodiversity into national and international security risk assessments and strategies.

Call to Action

It is our duty to alert the world to the threats to security and state stability posed by compromised food production systems and the loss of agricultural biodiversity. We wish to highlight the need for greater attention and investment from all stakeholders across governance, including the security sector, as well as civil society and the private sector.

Leading international organizations in agricultural biodiversity conservation and agricultural research, philanthropies, multinational corporations, and representatives from governments share this concern and endorse this statement arising from discussions at the 2025 Munich Security Conference.

International Women’s Day: inclusion drives innovation

Written by dmedina on March 7, 2025. Posted in Features.

Integrating inclusive perspectives in agricultural research is critical to enhancing the livelihood trajectories and resilience of a diversity of resource-poor farmers. Recognizing this, CIMMYT identified gender commitment and capacity as key to achieving its 2030 Strategy. The aim is to ensure that women, equity, youth, and social inclusion are actively and meaningfully embedded into all CIMMYT research streams so that scientific advances promote equity and expand opportunities for women in agriculture.

Women are at the heart of resilient agrifood systems. Across the Global South, they grow food, manage farms, support families, and drive rural economies, yet they continue to face systemic barriers to resources, markets, and decision-making. CIMMYT works alongside women farmers, researchers, and policymakers to ensure that gender-responsive innovations reach those who need them most—whether through climate-smart seeds, inclusive digital advisory services, or strengthening women’s economic networks. From Ethiopia to Zambia, from India to Sudan, CIMMYT is driving evidence-based solutions that help women, enhance productivity, and improve livelihoods.

Differences in wheat varietal turnover go beyond distinctions between men and women farmers

Rapid varietal turnover is an important coping mechanism to risks arising from the spread of pests or diseases and a means of increasing crop yields from genetic innovations. However, a recent study under the Accelerated Genetic Gain (AGG) for wheat project in Bihar, India, shows that wheat varietal turnover is generally too slow. The study highlights that the Indian wheat sector is characterized by deep-rooted social inequalities, reflected in the social differentiation of wheat farmers based on identity, caste, ethnicity, wealth, and their intersectionality.

Using data collected from 759 wheat farmers in Bihar, the study explored whether these social groups are excluded from the adoption of new and improved wheat varieties. Results demonstrated only small differences in varietal turnover across heterogeneous social groups of farmers. There were only small differences in varietal turnover between female-headed and male-headed households, despite already low overall turnover rates across these groups. However, marginalized caste farmers appear to be more disadvantaged, as they tend to cultivate older wheat varieties, which deserves closer attention from policymakers.

Can targeted information campaigns through women’s institutions stimulate household seed purchases?

This study examines the impact of targeted information sessions on household fresh wheat seed purchases in Ethiopia, where seed distribution primarily occurs through farmer unions and cooperatives. Despite women’s active role in farm decision-making, extension services often focus on men. This study tests whether disseminating information through women-dominated networks enhances seed purchases. Results show that information transmission through economic and social networks positively influences household participation. However, no significant differences are found between male-only and mixed-gender channels. Effects are strongest in households where women participate in wheat production decisions.

Redesigning technology testing strategies to incorporate practices associated with women

To stimulate demand by seed companies to replace old varieties, a novel nuclear genetic technology was developed to reduce the complexity of hybrid maize seed production. Hybrid seed produced using this technology also has a yield benefit to farmers under low-input conditions. As women typically use less fertilizer than men, they were identified as primary beneficiaries of this technology.

It is important that new technologies are evaluated under the real-world conditions farmers face. In Zimbabwe, women are more likely to plant recycled hybrid maize seed in years when drought is predicted. Based on this knowledge, the evaluation of this new genetic technology was expanded to investigate if different recycling scenarios of hybrid maize seed produced using this technology could provide a yield benefit. Although recycled hybrid maize seed reduces potential yield, in years that farmers cannot afford to plant only hybrid maize, this technology offers a yield benefit compared to conventional hybrid seed. This study highlights how social considerations can be incorporated into new product design and testing strategies.

Digital inclusion in agricultural advisory in Zambia

Agricultural advisory services in sub-Saharan Africa have not equitably reached or benefited women and marginalized groups, but newer voice-based, mobile-phone platforms in local languages may help overcome literacy, time, and mobility constraints. This study, using a randomized controlled trial (RCT) with 2,800 Zambian farmers, evaluates how different combinations of digital and in-person advisory approaches impact trust and participation in advisory services, Climate-Smart Agriculture (CSA) knowledge, adoption of CSA practices, maize yields, and inclusion in decision-making among women, men, and youth.

Findings will contribute to ongoing dialogue among researchers, digital extension tool designers, donors, and implementers, providing empirical evidence and best practices for developing socially inclusive digital advisory systems that strengthen the role of women and youth in smallholder agriculture.

Gender and agricultural entrepreneurship during Sudan’s civil war

This study explores the intersection of gender, entrepreneurship, and conflict in Sudan, examining how war has reshaped agribusiness opportunities, challenges, and dynamics. Using phone-based survey data and in-person, in-depth interviews, we find that women’s participation in agribusiness has increased, driven by economic necessity as men’s incomes decline and living costs rise, and with targeted NGO initiatives supporting women entrepreneurs.

However, women’s greater involvement has not been accompanied by a narrowing of gender gaps in financial outcomes: women-owned businesses persistently generate lower sales than those owned by men. Encouragingly, social norms around women’s mobility and public economic roles appear to be loosening. War-induced migration of businesswomen from Khartoum, where women’s entrepreneurship is more socially accepted, to more conservative states could play a role in relaxing traditional roles and demonstrating that women are capable entrepreneurs who can contribute importantly to both their families’ and their communities’ economies.

Innovation and Partnerships for a Food, Nutrition, and Climate-Secure Future

Written by dmedina on March 6, 2025. Posted in News.

Every two years, CIMMYT hosts its Science and Innovation Week (SIW), a moment not only for reflection but also for action. SIW2025 is more than a gathering; it is a call to action, challenging us to create lasting change and transformative impact. Each day, we wake up with a bold mission: to make our work meaningful to the ultimate beneficiaries – smallholder farmers.

To kick off this year’s Science Week, CIMMYT Director General Bram Govaerts reminded participants that at the heart of our work is real-world impact. More than an opportunity to evaluate strategies, Science Week is about envisioning and driving the future of food systems.

“CIMMYT’s work connects communities worldwide, from labs to corn harvests. Your tireless research deserves accolades as profound as a Nobel Prize” said Ted McKinney, CEO of the JS National Association of State Departments of agriculture, NASDA & Former USDA Undersecretary. Recognizing this urgency, CIMMYT convened leading scientists, researchers, and decision-makers at its headquarters in Texcoco, Mexico, for Science Week 2025.

This flagship event brought together experts at the intersection of agriculture, climate and food security to foster collaboration and inspire action for resilient food systems. With CIMMYT’s research agenda focused on addressing the world’s most pressing agricultural challenges, Science Week served as a key platform to shape the future of innovation, strengthen partnerships, and accelerate impact on global food security. Through knowledge sharing and strategic discussions, participants explored transformative solutions that will empower smallholder farmers, build crop resilience, and ensure a sustainable future for food systems worldwide.

A platform for collaboration and innovation

The first day set the stage for a dynamic exchange of ideas, bringing together global experts to address agriculture’s most pressing challenges. Discussions explored climate-smart agriculture, the role of digital transformation, and the resilience of seed systems, highlighting the need for innovation to ensure food security. Advances in crop breeding and cutting-edge research took center stage, reinforcing CIMMYT’s commitment to developing scalable, science-based solutions that empower farmers.

Sessions covered a wide range of topics, including climate-smart agriculture, digital transformation in agriculture, resilience of seed systems, and advances in crop breeding. High-level panels and thought leaders highlighted the importance of collaboration, from integrating AI and strategic partnerships to amplifying research impact, while deep diving into CIMMYT’s scientific breakthroughs. The challenge was clear: think beyond the event, push boundaries, and make a meaningful impact that extends far beyond this week.

From data-driven decision-making to sustainable food production, discussions reinforced the need for strategic collaboration, digital transformation, and responsible innovation. With a strong focus on open data and climate resilience, day two underscored CIMMYT’s commitment to translating science into real-world impact for farmers and food systems worldwide.

With CIMMYT generating around 122 datasets annually, experts stressed the importance of improving data quality, integrating new information, and standardizing workflows for greater transparency and efficiency. The discussions also tackled food security, conflict, and economic instability. With 8.4 million people affected by food insecurity in Latin America and the Caribbean, experts highlighted the urgent need for social protection systems, digital solutions, and adaptive policies.

Moving forward, CIMMYT must bridge science and action, ensuring that research translates into tangible solutions for farmers and food systems worldwide – because resilience is not just an option; it is the foundation of sustainable agriculture.

Scientific excellence in action

As Science Week 2025 drew to a close, discussions focused on two key themes: partnerships and communicating impact. To kick off the session, Aaron Maniam, Fellow of Practice and Director, Digital Transformation Education, Oxford University Blavatnik School, challenged participants to rethink collaboration – not just as coordination but as a balance between integration and fragmentation. Collaboration is non-negotiable, and positioning CIMMYT as the partner of choice will be critical to advancing its mission.

Today’s challenges are too complex to tackle alone, and strategic partnerships are essential to amplify impact, leverage resources, and scale innovation. But successful partnerships go beyond collaboration – they require trust and shared goals. Science must be accessible, compelling, and strategically packaged to engage diverse audiences and drive real-world change. As we move forward, the challenge is clear: Embrace, amplify, and boldly communicate our impact to shape the future of food and agriculture. The work does not stop here, this is just the beginning of the next chapter in transforming global food systems for a food and nutrition secure world.
