CGIAR webinar unleashes multidisciplinary approach to climate change and plant health

Evidence of enormity and immediacy of the challenges climate change poses for life on earth seems to pour in daily. But important gaps in our knowledge of all the downstream effects of this complex process remain. And the global response to these challenges is still far from adequate to the job ahead. Bold, multi-stakeholder, multidisciplinary action is urgent.

Mindful of this, the first event in Unleashing the Potential of Plant Health, a CGIAR webinar series in celebration of the UN-designated International Year of Plant Health, tackled the complicated nexus between climate change and plant health. The webinar, titled “Climate change and plant health: impact, implications and the role of research for adaptation and mitigation,” convened a diverse panel of researchers from across the CGIAR system and over 900 audience members and participants.

In addition to exploring the important challenges climate changes poses for plant health, the event explored the implications for the wellbeing and livelihoods of smallholder farming communities in low- and middle- income countries, paying special attention to the gender dimension of both the challenges and proposed solutions.

The event was co-organized by researchers at the International Rice Research Institute (IRRI) and the International Centre of Insect Physiology and Ecology (icipe).

The overall webinar series is hosted by the International Maize and Wheat Improvement Center (CIMMYT), the International Potato Center (CIP), the International Food Policy Research Institute (IFPRI), the International Institute of Tropical Agriculture (IITA) and the International Rice Research Institute (IRRI). It is sponsored by the CGIAR Research Program on Agriculture for Nutrition (A4NH), the CGIAR Gender Platform and the CGIAR Research Program on Roots, Tubers and Bananas (RTB).

This is important

The stakes for the conversation were forcefully articulated by Shenggen Fan, chair professor and dean of the Academy of Global Food Economics and Policy at China Agricultural University and member of the CGIAR System Board. “Because of diseases and pests, we lose about 20-40% of our food crops. Can you imagine how much food we have lost? How many people we could feed with that lost food? Climate change will make this even worse,” Fan said.

Such impacts, of course, will not be evenly felt across geographic and social divides, notably gender. According to Jemimah Njuki, director for Africa at IFPRI, gender and household relationships shape how people respond to and are impacted by climate change. “One of the things we have evidence of is that in times of crises, women’s assets are often first to be sold and it takes even longer for them to be recovered,” Njuki said.

Shifting risks

When it comes to understanding the impact of climate change on plant health “one of our big challenges is to understand where risk will change,” said Karen Garrett, preeminent professor of plant pathology at the University of Florida,

This point was powerfully exemplified by Henri Tonnang, head of Data Management, Modelling and Geo-information Unit at icipe, who referred to the “unprecedented and massive outbreak” of desert locusts in 2020. The pest — known since biblical times — has reemerged as a major threat due to extreme weather events driven by sea level rise.

Researchers highlighted exciting advancements in mapping, modelling and big data techniques that can help us understand these evolving risks. At the same time, they stressed the need to strengthen cooperation not only among the research community, but among all the stakeholders for any given research agenda.

“The international research community needs to transform the way it does research,” said Ana María Loboguerrero, research director for Climate Action at the Alliance of Bioversity International and CIAT. “We’re working in a very fragmented way, sometime inefficiently and with duplications, sometimes acting under silos… It is difficult to deliver end-to-end sustainable and scalable solutions.”

Time for a new strategy

Such injunctions are timely and reaffirm CGIAR’s new strategic orientation. According to Sonja Vermeulen, the event moderator and the director of programs for the CGIAR System Management Organization, this strategy recognizes that stand-alone solutions — however brilliant — aren’t enough to make food systems resilient. We need whole system solutions that consider plants, animals, ecosystems and people together.

Echoing Fan’s earlier rallying cry, Vermeulen said, “This is important. Unless we do something fast and ambitious, we are not going to meet the Sustainable Development Goals.”

The CGIAR Research Program on Maize (MAIZE) “uniquely fills a gap at the global and regional level, positioning it to continue catalyzing good science across borders,” according to a new report.

Commissioned by the CGIAR Advisory Services Shared Secretariat (CAS Secretariat), the report assesses the research-for-development program’s achievements and operations over the course of its second phase, from 2017-2019.

The reviewers commend MAIZE’s “valuable” technology transfer in the areas of double haploid production and stress-tolerance phenotyping, as well as its “proactive and productive” incorporation of crosscutting gender and youth focused issues in major projects such as Stress Tolerant Maize for Africa (STMA). They note that climate change is “central to all that the [program] is doing.”

In addition to the exceptional quality of the program’s scientific inputs and the overall quality of its outputs, the reviewers note the program’s capacity to mobilize “stakeholders, resources and knowledge to rapidly deliver valuable solutions for a critical need.” The review authors specifically note MAIZE’s efforts towards halting the spread of maize lethal necrosis (MLN).

While, like all CGIAR Research Programs, MAIZE is due to conclude at the end of 2021, much of the program’s pioneering work will continue under new guises, such as the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project.

“As we move towards the implementation of One CGIAR, MAIZE’s expertise in increasing genetic gains in tropical and sub-tropical, stress-prone environments through the integration of advanced breeding methodologies, a strong phenotyping network for various abiotic and biotic stresses, improved agronomic practices, and a rich network of public-private partnerships for scaling and deploying climate resilient improved maize varieties in Africa, Asia and Latin America — not to mention its capacity to respond quickly and successfully to devastating transboundary diseases and pests through multidisciplinary and multi-institutional initiatives — will be extremely valuable,” says B.M. Prasanna, director of MAIZE and of the International Maize and Wheat Improvement Center’s (CIMMYT) Global Maize Program.

MAIZE — led by CIMMYT in partnership with the International Institute of Tropical Agriculture (IITA) — spearheads international, multi-stakeholder research for development to improve the livelihoods and food security of poor maize producers and consumers. It simultaneously seeks to strengthen the sustainability of maize-based agri-food systems. The program focuses on maize production in low- to middle-income countries — accounting for approximately two-thirds of global maize production — where the crop is “key to the food security and livelihoods of millions of poor famers,” according to the report.

“MAIZE provides a very robust platform for collaboration with our national partners, including private companies, community seed produces and other stakeholders. Through projects such as Drought Tolerant Maize for Africa (DTMA) and STMA, research has been able to provide innovative solutions to challenges that smallholder farmers face in their daily lives, such as drought, poor soils, and pests and diseases,” says Nteranya Sanginga, IITA’s Director General.

The review concludes that MAIZE “good management and governance practice are a strong foundation for the remainder of [the program’s] running.” The reviewers also recommend that the “excellent,” participatory application of theory of change thinking in the second phase of MAIZE be mainstreamed at the CGIAR system level moving forward. Key recommendations for the program’s final phase include:

  • Building on MAIZE’s “strong network of partners” by deepening these relationships into “multidirectional partnerships.”
  • Building on existing cross-cutting work on capacity development, climate change, gender and youth.
  • Diversifying and expanding MAIZE’s knowledge dissemination efforts to more deeply engage with include multiple and non-scientific audiences.

Honoring the life and legacy of Byrd C. Curtis

The International Maize and Wheat Improvement Center (CIMMYT) sadly notes the passing of Byrd C. Curtis, former Director of the Global Wheat Program, on January 7. He was 95 years old and lived in Fort Collins, Colorado, USA, with his wife Eloise Curtis.

From his studies at Oklahoma State University to retiring after a fruitful international career with Colorado State University, Cargill Inc. and CIMMYT, he never got weary of sharing his passion for breeding better, tastier and sturdier wheat to improve peoples’ livelihoods.

He was an innovator at heart and his legacy will live on through Colorado State University’s wheat breeding program and the many wheat varieties he developed. Not only did he start Colorado State University’s wheat breeding program in 1963, but he also ensured that the varieties that were bred by his team reflected the needs of humanity for decades to come, such as the hard, red winter wheat variety named after himself.

Curtis worked at CIMMYT from 1982 and 1988 as Director of the Global Wheat Program. Together with his team, he worked to position CIMMYT as the leading international research-for-development and breeding organization for wheat for years to come.

“Byrd was very keen to build oral communication skills of scientists, which has been very helpful to me,” said Ravi Singh, Head of Global Wheat Improvement at CIMMYT. “He also initiated the Turkey-CIMMYT-ICARDA International Winter Wheat Improvement Partnership’s (IWWIP) winter wheat breeding program and even worked there in Turkey in his final year with CIMMYT to ensure it would take off well.”

Byrd was instrumental and showed tremendous foresight. IWWIP’s establishment in Turkey became first major breeding program within CGIAR that was hosted by a national program. He strongly supported the creation of the Wide Crossing Program. The synthetic wheat varieties developed in this program have had global impact on wheat improvement.

Aside from his remarkable technical legacy, Byrd had a knack for choosing the right people for the job. In the six years as Director of the Global Wheat Program, he hired scientists who held major roles in global wheat improvement: Ravi Singh, Distinguished Scientist and Head of Global Wheat Improvement; Wolfgang Pfeiffer, former leader of spring bread wheat, durum wheat, and triticale crop improvement; and Hans Braun, Director of the Global Wheat Program from 2004 to 2020.

“Byrd not only initiated the winter wheat program,” said former Global Wheat Program Director Hans Braun, who was hired by Byrd in 1983. “He was also director when the tropical wheat program was implemented in Thailand.” This program’s work increased yields up to 1.5 tons per hectare but ultimately did not convince Thai farmers. Nevertheless, Braun said, “One of the oddest experiences I’ve had was to see our winter wheat material from Turkey grown in the Thai jungle!”

After retiring from his professional life in 1991, Curtis and his wife Eloise moved back to Fort Collins, where his career started in the 1960s and where he will be remembered by his townspeople — and fellow athletes and gym-goers — for his determination and active lifestyle.

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

FFAR grant develops climate-resilient wheat

Wheat constitutes 20% of all calories and protein consumed, making it a cornerstone of the human diet, according to the United Nations. However, hotter and drier weather, driven by a changing climate, threatens the global wheat supply. To address this threat, the Foundation for Food and Agriculture Research (FFAR) awarded a $5 million grant to the International Maize and Wheat Improvement Center (CIMMYT) to develop climate-resilient wheat. CIMMYT leads global research programs on maize and wheat, sustainable cropping systems and policies to improve farmers’ livelihoods. These activities have driven major gains in wheat variety improvement across the globe for decades; in the US alone, for example, over 50% of the wheat acreage is sown with CIMMYT-related varieties.

Wheat is among the most widely grown cereal crops in the world and the third-largest crop grown in the US by acre. Nearly all US wheat crops are improved and supported by public agriculture research. As most wheat in the US is dependent on rainfall and has no access to irrigation, this research is critical for helping the plants — and producers — weather climatic changes including extreme heat and drought. Additionally, the demand for wheat is expected to rise in the coming years — as much as 60% by 2050. Without public research, wheat production could decrease by nearly 30% over the same period due to extreme climate conditions.

“FFAR leverages public agriculture research funding through public-private partnerships to pioneer actionable research. With temperatures on the rise and water becoming scarcer, we are committed to supporting wheat farmers and providing new wheat varieties designed with future environmental challenges in mind,” said FFAR’s Executive Director Sally Rockey.

Using the FFAR grant, CIMMYT researchers are pioneering wheat breeding technologies to produce heat-tolerant, drought-resistant and climate-resilient wheat.

CIMMYT researchers and collaborators are applying cutting-edge approaches in genomics, remote sensing and big data analysis to develop new breeding technologies. A key intervention will explore the vast and underutilized reserve of wheat genetic resources to fortify the crop against current and future climate-related stresses.

“This project will help bridge a longstanding gap between state-of-the-art technological findings and crop improvement to deliver climate resilient wheat to farmers as quickly as possible,” said Matthew Reynolds, head of Wheat Physiology at CIMMYT and principal investigator of the project.

Breakthroughs from the FFAR funded project will achieve impact for growers via the International Wheat Improvement Network (IWIN) that supplies new wheat lines to public and private breeding programs worldwide, and has boosted productivity and livelihoods for wheat farmers for over half a century, especially in the Global South.

The research and breeding supported by FFAR will be conducted under the Heat and Drought Wheat Improvement Consortium (HeDWIC), a project led by CIMMYT in partnership with experts across the globe, designed to ensure wheat’s long-term climate resilience. Under the umbrella of the Wheat Initiative’s AHEAD unit, the most relevant advances in academia will be channeled to HeDWIC to help further boost impacts.

“‘Heat,’ ‘drought’ and ‘wheat’ are three of the most important words for billions of people,” said CIMMYT Interim Deputy Director for Research Kevin Pixley. “This partnership between CIMMYT and FFAR will help ensure that the best agricultural science is applied to sustainably raise production of one of the world’s most important staple crops, despite unprecedented challenges.”

CIMMYT Director General Martin Kropff said, “This project represents not only a breakthrough to develop wheat for the future, but also an emerging partnership between CIMMYT and FFAR. I look forward to a productive collaboration that will move us all closer to our mission of maize and wheat science for improved livelihoods.”

FFAR’s investment was matched by co-investments from the CGIAR Research Program on Wheat (WHEAT) and Accelerating Genetic Gains for Maize and Wheat (AGG), a project which is jointly funded by  the Bill & Melinda Gates Foundation and the UK Foreign, Commonwealth, and Development Office (FCDO).

Unleashing the potential of plant health

The UN has designated 2020 as the International Year of Plant Health. CGIAR Centers have significant scientific knowledge, extensive experience on the ground, and thought leadership that they can lend to the global discussion to advance awareness, collaboration, and scaling of needed interventions.

CGIAR’s International Year of Plant Health events will comprise a series of four webinars of global scope targeting scientists and researchers working in relevant fields. The webinars will take an in-depth look into current science in the area, identify areas for further research, and opportunities to take current scientific innovations to scale.

Each webinar will examine one aspect of the crop supply chain — from genebanks to farmers’ fields to consumers’ plates — to identify ways of promoting the adoption of tools and practices designed to boost the long-term health of plants and the environment in low- and middle-income countries. With the acceleration of the effects of climate change on the incidence and intensity of pests and diseases, identification of the right crop varieties, mix of crops, and tools and practices will be key to ensuring the availability of food to feed the planet.

Webinar series

Webinar 1: Climate change and plant health: impact, implications and the role of research for adaptation and mitigation

January 28, 2021 – 13:00 GMT

Webinar 1 will discuss the anticipated impacts of climate change on plant health in smallholder systems, tackling how the occurrence, intensity, and frequency of biotic and abiotic stresses will change as a function of climate change. It will provide participants with information on the negative effects on plant health, in relation to food security, nutrition, environment, gender, and livelihoods, as well as on the role of research in providing support to global efforts to mitigate or adapt to climate change challenges for plant health. Full details of webinar 1.

Webinar 2: Germplasm health in preventing transboundary spread of pests and pathogens

February 17, 2021 – 12:00 GMT

Webinar 2 will highlight the importance of germplasm (phytosanitary) health in the prevention of transboundary pest and disease spread, as well as the propagation of clean planting material to be used locally. Experts will discuss the implications of poor germplasm practices on agricultural and food system sustainability, farmer livelihoods, and food and nutrition security. They will also examine how opportunities for greater workplace diversity in germplasm health hubs and gender-responsive programming could drive more inclusive sustainable development. Full details of webinar 2.

Webinar 3: Integrated pest and disease management

March 10, 2021 – 12:30 GMT

Webinar 3 examines integrated approaches for sustainable management of transboundary diseases and crop pests and their implications for agri-food system sustainability, social inclusion and gender equity. Drawing on both successes and enduring challenges, experts will identify the potential benefits of more gender-responsive approaches to pest and disease control; more coordinated action by national, regional and global organizations; and lessons to be learned from successful animal health management. Full details of webinar 3.

Webinar 4: A One Health approach

March 31, 2021 – 14:00 GMT

Webinar 4 brings together scientists working at the intersection of environmental, human, and animal health. In this session, the experts will examine plant health and agriculture from a “One Health” approach — a collaborative, multisectoral, and transdisciplinary perspective that recognizes the health of people, animals, plants, and their environments as all closely connected. In this approach, agricultural practices and plant health outcomes both are determined by, and contribute to, ecological, animal, and human health. Full details of webinar 4.

Taking stock of value chain development

In 1967 Albert O. Hirschman, the pioneering development economist, published Development Projects Observed. Based on an analysis of a handful of long-standing World Bank projects, the book was an effort, as Hirschman writes in the preface, “to ‘sing’ the epic adventure of development­ — its challenge, drama, and grandeur.” He sang this epic not in the register of high development theory,­ but rather through the ups and downs and unexpected twists of real-world development projects.

Today, a new group of researchers have taken up a similar challenge. Value Chain Development and the Poor: Promise, delivery, and opportunities for impact at scale, a new book edited by Jason Donovan, Dietmar Stoian and Jon Hellin, surveys over two decades of academic and practical thinking on value chains and value chain development. While value chain development encompasses a broad variety of approaches, it has largely focused on improving the ability of small scale, downstream actors — such as smallholders in agri-food value chains — to capture more value for their products or to engage in value-adding activities. Value chain development approaches have also focused on improving the social and environmental impacts of specific value chains. Donovan, Stoian and Hellin’s book assesses these approaches through careful analysis of real-world cases. The book was published with support from the CGIAR Research Programs on Maize and on Policies, Institutions, and Markets.

Lessons learned

The book takes an unsparing look at what has and hasn’t worked in the field of value chain development. It begins by dissecting the drivers of the high degree of turnover in approaches that characterizes the field. The editors argue that “issue-attention cycles” among project stakeholders, coupled with monitoring and evaluation metrics that are more focused on tracking project implementation rather than producing robust measurements of their social impact, too often lead to the adoption — and abandonment — of approaches based on novelty and buzz.

The unfortunate consequences are that strengths and limitations of any given approach are never fully appreciated and that projects — and even entire approaches — are abandoned before they’ve had a chance to generate deep social impacts. Moreover, the opportunity to really learn from development projects — both in terms of refining and adapting a given approach to local conditions, and of abstracting scalable solutions from real development experiences — is lost.

A recurring theme throughout the book is the tension between the context-sensitivity needed for successful value chain development interventions and the need for approaches that can be scaled and replicated. Programs must develop tools for practitioners on one hand and demonstrate scalability to funders on the other. For example, a chapter on maize diversity and value chain development in Guatemala’s western highlands illustrates how an approach that was successful in Mexico — connecting producers of indigenous maize landraces with niche markets — is ill-suited to the Guatemalan context, where most producers are severely maize deficient. And a chapter reviewing guides for gender-equitable value chain development highlights how — for all their positive impact — such guides often overlook highly context- and culturally-specific gender dynamics. Intra-household bargaining dynamics and local masculinities, for example, can play critical roles in the success or failure of gender-focused value chain development interventions.

This new book takes an unsparing look at what has and hasn’t worked in the field of value chain development.
This new book takes an unsparing look at what has and hasn’t worked in the field of value chain development.

Finally, while lauding the valuable impact many value chain development initiatives have achieved, the editors warn against an exclusive reliance on market-based mechanisms, especially when trying to benefit the poorest and most marginalized of smallholders. In the case of Guatemala’s maize-deficient highland farmers, for example, the development of niche markets for native maize proved to be a poor mechanism for achieving the stated goal of preserving maize biodiversity and farmers’ livelihoods. Non-market solutions are called for. Based on this and similar experiences, the editors note that, while value chain development can be a valuable tool, to truly achieve impact at scale it must be coordinated with broader development efforts.

“The challenge of ensuring that value chain development contributes to a broad set of development goals requires transdisciplinary, multisector collaboration within broader frameworks, such as integrated rural-urban development, food system transformation, and green recovery of the economy in the post COVID-19 era,” write the editors.

This bracing and clear reflection on the promise and limitations of current development approaches is not only timely; it is perhaps more urgent today than in Hirschman’s time. While tremendous gains have been made since the middle of the 20th century, many stubborn challenges remain, and global climate change threatens to undo decades of progress. Projects like Value Chain Development and the Poor and the ongoing Ceres2030 initiative provide development practitioners, researchers, funders and other stakeholders a much needed assessment of what can be built upon and what needs to be rethought as they tackle these gargantuan challenges.

Embracing uncertainty

At the time Development Projects Observed was published, the study and practice of development was already entering a crisis of adolescence, as it were. Having achieved quasi-independence from its parent discipline of economics, it had to settle on an identity of its own.

Hirschman’s book represented one possible way forward — an understanding of development practice as a blend of art and science. The book’s most famous concept, that of the Hiding Hand, illustrates how planners’ optimism could fuel enormously complex and challenging projects — undertakings that might never have been attempted had all the challenges been known beforehand. At the same time, projects’ inevitable failures and shortcomings could spur creative local responses and solutions, thus ensuring their eventual success and rootedness in their specific context.

As Michele Alacevich points out in the Afterword to the book’s most recent reissue, the World Bank’s response to Hirschman’s book demonstrates the road that development research and practice ultimately took. The book was disregarded, and the Bank turned to the growing literature on cost-benefit analysis instead. “Whereas Hirschman’s analysis had placed uncertainty — an unmeasurable dimension — center stage, cost-benefit analysis assimilated it to risk, therefore turning it into something measurable and quantifiable,” Alacevich writes. Faced with a newfound awareness of the limits to the field’s powers and abilities — a rite of passage for all prodigies — development institutions appeared to try to outrun these limitations through ever-increasing technification.

The issue-attention cycles identified by Stoian and Donovan may represent a new, more frenetic and self-defeating iteration of this discomfort with uncertainty. If so, Value Chain Development and the Poor serves as an urgent call for development institutions and practitioners to make peace with the messiness of their vocation. As Hirschman observed decades ago, only by embracing the uncertainty and art inherent in development work can its students and practitioners further the enormously complex scientific understanding of the endeavor, and, crucially, generate broad and lasting social change.

The International Maize and Wheat Improvement Center (CIMMYT) congratulates the winners of the inaugural 2020 Bӓnziger Award.

The award is named for former CIMMYT Deputy Director General Marianne Bӓnziger, who retired in 2019 after 23 years in maize science and leadership, including as CIMMYT’s first woman to reach the Deputy Director General position. It recognizes the contribution of women to CIMMYT’s work and mission. Nominees must exemplify one or more of the core values of CIMMYT: teamwork, integrity, excellence and respect.

“Gender diversity is critical to the development of robust and impactful science,” said CIMMYT Director General Martin Kropff, speaking at the virtual award ceremony during an all-staff CIMMYT end-of-year celebration on December 15.

“Research and administration have been demonstrated time and time again to be more effective and efficient when gender is considered, because women bring unique perspectives to conversations and decisions.”

The inaugural Bӓnziger Award received more than 50 nominations from across the organization’s offices in Africa, Asia and Latin America. Because of the high number of excellent candidates, the 2020 award committee selected two winners: Rahel Assefa and Kate Dreher.

Rahel Assefa is a project manager based in Ethiopia who has spent nearly five years supporting CIMMYT programs in eastern and southern Africa. In their nomination, her colleagues emphasized her “can-do” attitude and problem-solving skills as well as her positivity, maintained even when “deadlines are tight and tensions are high.”

“The nominations for Rahel covered all bases — teamwork, integrity, excellence and respect,” explained Sarah Hearne, a maize molecular geneticist at CIMMYT and chair of the 2020 award committee. “She was praised for her openness, collaboration and support of colleagues, both in and outside of her immediate environment and program.”

“I am grateful to my colleagues for the recognition of my contributions to CIMMYT,” said Rahel Assefa. “It is nice to be awarded — even though it is not why we do what we do. I like my work and I enjoy my colleagues in Africa and at HQ, and more than anything I believe in teamwork and collaboration.”

Kate Dreher is a senior germplasm curator based at CIMMYT HQ in Mexico. Her award focused not only on her official duties but also on her charity and community-building work in larger the El Batan and Texcoco area — including leading the Charity Initiative and organizing countless gatherings and activities for staff, newcomers and visitors to CIMMYT HQ.

“Nominees told us that Kate goes extra mile to help others succeed, selflessly focusing on ‘we’ rather than ‘I’ and ensuring that the voices and needs of all in a team are heard — a fantastic example of empowering teams,” said Hearne.

“Her hard work, kindness and dedication not only apply to CIMMYT’s mission enhance the CIMMYT community as a whole, touching the lives of colleagues and those less fortunate within the communities where we work.”

Dreher expressed that this recognition would encourage her to redouble her efforts to follow Bӓnziger’s example.

“I feel inspired when I see people trying to improve the well-being of others — at work and in life in general — and I feel uplifted by the countless daily examples that I see in the CIMMYT community of people trying to make a positive impact in the world,” she said. “I admire everyone who is motivated by this goal whether their actions have an immediate impact or will lead to positive outcomes many years in the future.”

Marianne Bӓnziger shared her appreciation for the fact that CIMMYT has installed the award in her name. Speaking at the ceremony, she reiterated the words inscribed on the plaques, and offered advice for all CIMMYT staff.

“The header of the award says ‘Diversity enriches every team. Women make CIMMYT stronger,’” she told ceremony attendees. “Let’s open our eyes to the contribution that diverse team members make: women and men, young and more experienced, staff in research and administration, staff from different nations.”

“This award celebrates excellence among women staff. It’s a call to everybody to find, celebrate and foster diversity; to find, celebrate and foster excellence. Diversity in views and contributions make us stronger, and life much more colorful.”

No greater challenge

Amidst the transition to One CGIAR and COVID-19 lockdowns, the world’s leading maize and wheat research organization’s community found the time to slow down and weigh the successes and bottlenecks of this complicated year. More than 400 people spread across the International Maize and Wheat Improvement Center’s (CIMMYT) 13 offices worldwide gathered for an all-staff virtual event to close 2020.

Aided by world-renowned economist Jeffrey Sachs’ vast experience in detangling global crises, sustainable development and poverty alleviation, staff reflected on the role they play within CGIAR and in helping CIMMYT increase its impact on nutrition security, poverty alleviation and a better world.

Connecting from his home in New York, Sachs urged CGIAR to see beyond the research priorities it set out to accomplish a half a century ago. With the 50th anniversary of CGIAR in 2021, Sachs encouraged CGIAR to think about the research priorities for the next 50 years. “We’re confronting a probably more systemic and even more complex set of challenges in food in 2021, than perhaps was the case in 1971,” he said.

“We need to expand the research agenda beyond the still-important focus on improved yields and varieties to consider the food system holistically. Our goal is a global food system that enables healthy diets, sustainable land use, resilience to environmental change, and good livelihoods for farm families.”

“Our goal is a global food system that enables healthy diets, sustainable land use, resilience to environmental change, and good livelihoods for farm families.”

Albeit not as famous as its colleague organizations the Food and Agriculture Organization of the UN (FAO) and the World Food Programme (WFP), CGIAR has been called “essential to feeding our future” by Bill Gates. Sachs echoed this sentiment and urged CGIAR to embrace its vital role in “achieving sustainable agriculture and healthy diets for all.”

The next 50 years

As CIMMYT moves into One CGIAR, it will capitalize on its over 50 years of experience, impact and expertise in genetic innovations, systems transformation and tools for resilient agri-food systems and fully embrace One CGIAR’s mission of delivering science and innovation that advance transformation of food, land and water systems in a climate crisis.

Throughout 2020, COVID-19 and global conflicts have put an almost impossible pressure on already overwhelmed agricultural production, smallholders’ livelihoods and global supply chains. As with any system, it requires resilience for its long-term sustainability. “Of course, CGIAR’s central goal has been to anticipate the future needs of food production and areas of new resilience such as flood resilience or drought,” said Sachs.

“I would add [for its future strategy to also consider] resilience to social disruptions and disruptions to global supply chains, as we experience with COVID-19 but also with geopolitical tensions,” he advised.

Keeping cereals in the equation

While diversification is important to human diets and the sustainability of agricultural production, we cannot afford to ignore the major cereals. Maize, rice and wheat provide a basic nutritional value, macro- and micronutrients that many people across the globe can afford and access.

Sachs asked CGIAR to look deeply at the question of poverty and food poverty, both in rural and urban areas. “CGIAR has more knowledge of how smallholders are living and how their lives are changing than any other research institution in the world. And I think your work can therefore give tremendous guidance on the overall fight against poverty and on the anticipation of increased urbanization in future years, as agriculture becomes more mechanized, and as smallholders or the children of today’s smallholders leave for urban areas in the coming generation.”

“CGIAR has more knowledge of how smallholders are living and how their lives are changing than any other research institution in the world. And I think your work can therefore give tremendous guidance on the overall fight against poverty.”

Sachs acknowledged the large and important task that CGIAR faces in its future. “All of this is incredibly difficult. […] I find the food system challenges to be the most complex of all of the sustainability challenges we face.”

He spoke of the task at hand with urgency and that there is no greater intellectual challenge than the transformation to sustainable agriculture: “The role of the CGIAR will be unique and indispensable in helping to guide us through those transformations. I think this is the indispensable time for the CGIAR to lay out its new research agenda for the next 50 years to be the one that helps us to achieve the Sustainable Development Goals and the Paris Climate Agreement.”

Agriculture for Peace: A call to action to avert a global food crisis

50 years ago, the late Norman Borlaug received the 1970 Nobel Peace Prize for averting famine by increasing wheat yield potential and delivering improved varieties to farmers in South Asia. He was the first Nobel laureate in food production and is widely known as “the man who saved one billion lives.”

In the following decades, Borlaug continued his work from the Mexico-based International Maize and Wheat Improvement Center (CIMMYT), a non-profit research-for-development organization funded by the Rockefeller Foundation and the governments of Mexico and the United States.

CIMMYT became a model for a future network of publicly-funded organizations with 14 research centers: CGIAR. Today, CGIAR is led by Marco Ferrroni, who describes it as a global research partnership that “continues to be about feeding the world sustainably with explicit emphasis on nutrition, the environment, resource conservation and regeneration, and equity and inclusion.”

Norman Borlaug’s fight against hunger has risen again to the global spotlight in the wake of the most severe health and food security crises of the 21st Century. “The Nobel Peace Prizes to Norman Borlaug and the World Food Programme are very much interlinked,” said Kjersti Flogstad, Executive Director of the Oslo-based Nobel Peace Center. “They are part of a long tradition of awarding [the prize] to humanitarian work, also in accordance with the purpose [Alfred] Nobel expressed in his last will: to promote fraternity among nations.”

During welcome remarks at the virtual 50-year commemoration of Norman Borlaug’s Nobel Peace Prize on December 8, 2020, Mexico’s Secretary of Agriculture and Rural Development Víctor Villalobos Arámbula, warned that “for the first time in many years since Borlaug defeated hunger in Southeast Asia, millions of people are at risk of starvation in several regions of Africa, Asia and Latin America.”

According to CIMMYT’s Director General Martin Kropff, celebrating Norman Borlaug’s legacy should also lead to renewed investments in the CGIAR system. “A report on the payoff of investing in CGIAR research published in October 2020 shows that CIMMYT’s return on investment (ROI) exceeds a benefit-cost ratio of 10 to 1, with median ROI rates for wheat research estimated at 19 and for maize research at 12.”

Mexico’s Foreign Affairs Department echoed the call to invest in Agriculture for Peace. “The Government of Mexico, together with the Nobel Peace Center and CIMMYT, issues a joint call to action to overcome the main challenges to human development in an international system under pressure from conflict, organized crime, forced migration and climate change,” said Martha Delgado, Mexico’s Under Secretary of Multilateral Affairs and Human Rights.

The event called for action against the looming food crises through the transformation of food systems, this time with an emphasis on nutrition, environment and equality. Speakers included experts from CGIAR, CIMMYT, Conservation International, Mexico’s Agriculture and Livestock Council, United Nations Food and Agriculture Organization (FAO), United States Agency for International Development (USAID) and the World Food Programme (WFP), among others. Participants discussed the five action tracks of the 2021 United Nations Food Systems Summit: (1) ensure access to safe and nutritious food for all; (2) shift to sustainable consumption patterns; (3) boost nature-positive production; (4) advance equitable livelihoods; and, (5) build resilience to vulnerabilities, shocks and stresses.

“This event underlines the need for international solidarity and multilateral cooperation in the situation the world is facing today,” said Norway’s Ambassador to Mexico, Rut Krüger, who applauded CIMMYT’s contribution of 170,000 maize and wheat seeds to the Global Seed Vault in Svalbard, Norway. “This number reflects the global leadership position of CIMMYT in the development of maize and wheat strains.”

Norman Borlaug’s famous words — “take it to the farmer” — advocated for swift agricultural innovation transfers to the field; Julie Borlaug, president of the Borlaug Foundation, said the Agriculture for Peace event should inspire us to also “take it to the public.”

“Agriculture cannot save the world alone,” she said. “We also need sound government policies, economic programs and infrastructure.”

CIMMYT’s Deputy Director General for Research and Partnerships, and Integrated Development Program Director Bram Govaerts, called on leaders, donors, relief and research partners to form a global coalition to transform food systems. “We must do a lot more to avert a hunger pandemic, and even more to put the world back on track to meet the Sustainable Development Goals of the 2030 Agenda.”

CIMMYT’s host country has already taken steps in this direction with the Crops for Mexico project, which aims to improve the productivity of several crops essential to Mexico’s food security, including maize and wheat. “This model is a unique partnership between the private, public and social sectors that focuses on six crops,” said Mexico’s Private Sector Liaison Officer Alfonso Romo. “We are very proud of its purpose, which is to benefit over one million smallholder households.”

The call stresses the need for sustainable and inclusive rural development. “It is hard to imagine the distress, frustration and fear that women feel when they have no seeds to plant, no grain to store and no income to buy basic foodstuffs to feed their children,” said Nicole Birrell, Chair of CIMMYT’s Board of Trustees. “We must make every effort to restore food production capacities and to transform agriculture into productive, profitable, sustainable and, above all, equitable food systems worldwide.”

Improved metrics for better decisions

By adopting best practices and established modern tools, national agricultural research systems (NARS) are making data-driven decisions to boost genetic improvement. And they are measuring this progress through tracking and setting goals around “genetic gain.”

Genetic gain means improving seed varieties so that they have a better combination of genes that contribute to desired traits such as higher yields, drought resistance or improved nutrition. Or, more technically, genetic gain measures, “the expected or realized change in average breeding value of a population over at least one cycle of selection for a particular trait of index of traits,” according to the CGIAR Excellence in Breeding (EiB)’s breeding process assessment manual.

CGIAR breeders and their national partners are committed to increasing this rate of improvement to at least 1.5% per year. So, it has become a vital and universal high-level key performance indicator (KPI) for breeding programs.

“We are moving towards a more data-driven culture where decisions are not taken any more based on gut feeling,” EiB’s Eduardo Covarrubias told nearly 200 NARS breeders in a recent webinar on Enhancing and Measuring Genetic Gain. “Decisions that can affect the sustainability and the development of organization need to be based on facts and data.”

Improved metrics. Better decisions. More and better food. But how are NARS positioned to better measure and boost the metric?

EiB researchers have been working with both CGIAR breeding programs and NARS to broaden the understanding of genetic gain and to supply partners with methods and tools to measure it.

The recent webinar, co-sponsored by EiB and the CIMMYT-led Accelerating Genetic Gains in Maize and Wheat (AGG) project, highlighted tools and services that NARS are accessing, such as genotyping, data analysis and mechanization.

Through program assessments, customized expert advice, training and provision of services and resources, EiB researchers are helping national partners arrive at the best processes for driving and measuring genetic gains in their programs.

For example, the EiB team, through Crops to End Hunger (CtEH), is providing guidelines to breeders to help them maximize the accuracy and precision, while reducing the cost of calculating genetic gains. The guidelines make recommendations such as better design of trials and implementing an appropriate check strategy that permits regular and accurate calculation of genetic gain.

A comprehensive example at the project level is EiB’s High-Impact Rice Breeding in East and West Africa (Hi-Rice), which is supporting the modernization of national rice programs in eight key rice-producing countries in Africa. Hi-Rice delivers training and support to modernize programs through tools such as the use of formalized, validated product profiles to better define market needs, genotyping tools for quality control, and digitizing experiment data to better track and improve breeding results. This is helping partners replace old varieties of rice with new ones that have higher yields and protect against elements that attack rice production, such as drought and disease. Over the coming years, EiB researchers expect to see significant improvements in genetic gain from the eight NARS program partners.

And in the domain of wheat and maize, AGG is working in 13 target countries to help breeders adopt best practices and technologies to boost genetic gain. Here, the EiB team is contributing its expertise in helping programs develop their improvement plans — to map out where, when and how programs will invest in making changes.

NARS and CGIAR breeding programs also have access to tools and expertise on adopting a continuous improvement process — one that leads to cultural change and buy-in from leadership so that programs can identify problems and solve them as they come up. Nearly 150 national breeding partners attended another EiB/AGG webinar highlighting continuous improvement key concepts and case studies.

National programs are starting to see the results of these partnerships. The Kenya Agricultural & Livestock Research Organization (KALRO)’s highland maize breeding program has undertaken significant changes to its pipelines. KALRO carried out its first-ever full program costing, and based on this are modifying their pipeline to expand early stage testing. They are also switching to a double haploid breeding scheme with support from the CGIAR Research Program on Maize (MAIZE), in addition to ring fencing their elite germplasm for future crosses.

KALRO has also adopted EiB-supported data management tools, and are working with the team to calculate past rates of genetic gains for their previous 20 years of breeding. These actions — and the resulting data — will help them decide on which tools and methods to adopt in order to improve the rate of genetic gain for highland maize.

“By analyzing historical genetic gain over the last 20 years, it would be interesting to determine if we are still making gains or have reached a plateau,” said KALRO’s Dickson LIgeyo, who presented a Story of Excellence at EiB’s Virtual Meeting 2020. “The assessment will help us select the right breeding methods and tools to improve the program.”

Other NARS programs are on a similar path to effectively measure and increase genetic gain. In Ghana, the rice breeding program at Council for Scientific and Industrial Research (CSIR) have developed product profiles, identified their target market segments, costed out their program, digitized their operations, and have even deployed molecular markers for selection.

With this increased expertise and access to tools and services, national breeding programs are set to make great strides on achieving genetic gain goals.

“NARS in Africa and beyond have been aggressively adopting new ideas and tools,” says EiB’s NARS engagement lead Bish Das. “It will pay a lot of dividends, first through the development of state-of-the-art, and ultimately through improving genetic gains in farmers’ fields. And that’s what it’s all about.”

The cereals imperative of future food systems

The 2019 EAT-Lancet Commission report defines specific actions to achieve a “planetary health diet” enhancing human nutrition and keeping resource use of food systems within planetary boundaries. With major cereals still supplying about one-third of calories required in the proposed diet, the way they are produced, processed, and consumed must be a central focus of global efforts to transform food systems. This article from our annual report argues three main reasons for this imperative.

Battling devastating viral diseases, also in plants

Maize lethal necrosis (MLN) has taught us that intensive efforts to keep human and plant diseases at bay need to continue beyond the COVID-19 crisis. We interviewed B.M. Prasanna, director of the Global Maize Program at CIMMYT and the CGIAR Research Program on Maize (MAIZE), to discuss the MLN success story, the global COVID-19 crisis, and the similarities in the challenge to tackle plant and human viral diseases.

We had a similar conversation with Hans Braun, Director of the Global Wheat Program and the CGIAR Research Program on Wheat, who taled to us about the need for increased investment in crop disease research as the world risks a food security crisis related to COVID-19.

Crop breeding and soil management must go hand in hand

There is a growing crisis beneath our feet. Scientists, soil specialists and policy-makers around the world are sounding the alarm about degrading soil conditions. And it is particularly stark in developing countries. In fact, about 40 per cent of soils in sub-Saharan Africa are already of poor quality.

Declining soil health causes poor crop yields, leading to further pressure on the soils as farmers struggle to meet food demands and eke out a living. Many farmers lack access to information or technologies to get out of this vicious cycle. If you are a farmer with the need to increase your yield in the face of these challenges, crop breeding and soil management offers a range of solutions as part of an Integrated Soil Fertility Management (ISFM) approach.

For instance, breeding programs which partner with CGIAR Excellence in Breeding (EiB) are working to deliver the best seed varieties for farmers to help them withstand harsh conditions and increase yields. Alongside this work, researchers are supporting farmers to adopt better agronomic practices, such as minimum tillage farming, crop rotation, proper spacing and planting date practices, the use of terracing or intercropping, or techniques to reduce water use.

Of course, breeding cannot happen in a vacuum. To protect soils and produce quality yields, these cropping measures should be closely matched to the best, context-appropriate soil management practices available to farmers, for instance around the type and timing of mineral fertilizer, along with organic sources like crop residues, compost or manure.

Indeed, a combination will bring the best results.  But most of the time accessing either improved variety or best agronomic practice represent a challenge for farmers in low income countries.

Here are three ways crop breeders can ensure they deliver the best seeds and create the best conditions for long-term crop production.

Include farmers, agronomic experts and extension services when defining product requirements

Strong connections among public breeding programs and extension and agronomic groups are vital. There is growing discussion regarding how to broaden our work to better consider all the factors that contribute to a successful breeding scheme: genotyping, environment and management (GxExM). However, defining the management component is not easy. Do we breed for conditions that farmers are actually working with, or breed for conditions that they should adopt?

A key to answer this question is a strong breeding team defining the traits needed and wanted by farmers. To design the best product profile, it is imperative to involve extension teams and other groups that work on the development of sustainable agronomic practices.

Properly manage research stations

Attention also needs to focus on the sustainability practices within research stations. It is all too easy to find degraded soil in public research stations. There are many reasons for this: inadequate long-term planning, lack of organized management structures, insufficient connections between breeding and agronomic teams, and lack of resources, to name a few.

Public research stations must serve as an example for the farmers in that specific region. Thus, it is not only what products we develop that matters, but also how we develop them. If we develop a good variety at the research station, but do so without adopting good agronomic practice, what example has been set for farmers and future generations? We need to ensure we invest in the best soil management practices along every step of the research phase.

Breed for specific soil characteristics

Once the breeding target is known, breeding for specific soil conditions is critical. This means developing varieties for soil conditions such as nutrient deficiencies or high salinity levels. CGIAR breeding programs have put in tremendous efforts with great impact here.

For example, AfricaRice and partners developed rice varieties branded ARICA (Advanced Rice Varieties for Africa) to be salt or iron toxicity tolerant, among other traits. This is helping farmers who farm under predominantly rainfed conditions, in which soils and yields are threatened by floods, droughts and toxicity.

Another standout product is Stress Tolerant Maize for Africa (STMA), led by the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA). Breeders have developed varieties that can thrive in low soil fertility conditions, along with resistance to other stresses such as pests and drought. The project has seen the adoption of new maize varieties by more than six million households across 13 countries, with some farms increasing yields by over 150 per cent.

Our soils depend on breeding for the future. Breeding is showing real results for improving yields, delivering better food, and increasing smallholder incomes. But its impact on ecosystems could go either way. With the right investments in relationships, good research practices, and delivering varieties matched to particular soil conditions, we can breed for the present and for the future.

It is time to invest in both crop breeding and soil management — as one vital package of innovations.
