Scientists convene in Kenya for intensive wheat disease training

An international cohort of scientists representing 12 countries gathered at the Kenya Agricultural and Livestock Research Organization (KALRO) station in Njoro for a comprehensive training course aimed at honing their expertise in wheat rust pathology.

The two-week program “Enhancing Wheat Disease Early Warning Systems, Germplasm Evaluation, Selection, and Tools for Improving Wheat Breeding Pipelines,” was a collaborative effort between CIMMYT and Cornell University and supported by the Wheat Disease Early Warning Advisory System (DEWAS) and Accelerating Genetic Gains in Maize and Wheat projects.

With a mission to bolster the capabilities of National Agricultural Research Systems (NARS), the training course attracted more than 30 participants from diverse corners of the globe.

Maricelis Acevedo, a research professor of global development at Cornell and the associate director of Wheat DEWAS, underscored the initiative’s significance. “This is all about training a new generation of scientists to be at the forefront of efforts to prevent wheat pathogens epidemics and increase food security all over the globe,” Acevedo said.

First initiated in 2008 through the Borlaug Global Rust Initiative, these training programs in Kenya have played a vital role in equipping scientists worldwide with the most up-to-date knowledge on rust pathogens. The initial twelve training sessions received support from the BGRI under the auspices of the Durable Rust Resistance in Wheat and Delivering Genetic Gain in Wheat projects.

This year’s training aims to prepare global scientists to protect against disease outbreaks that threaten wheat productivity in East Africa and South Asia. The course encompassed a wide array of practical exercises and theoretical sessions designed to enhance the participants’ knowledge in pathogen surveillance, diagnostics, modeling, data management, early warning assessments, and open science publishing. Presentations were made by DEWAS partners from the John Innes Centre, Aarhus University, the University of Cambridge and University of Minnesota.

The course provided practical, hands-on experience in selecting and evaluating wheat breeding germplasm, race analysis and greenhouse screening experiments to enhance knowledge of rust diseases, according to Sridhar Bhavani, training coordinator for the course.

“This comprehensive training program encompasses diverse aspects of wheat research, including disease monitoring, data management, epidemiological models, and rapid diagnostics to establish a scalable and sustainable early warning system for critical wheat diseases such as rusts, fusarium, and wheat blast,” said Bhavani, wheat improvement lead for East Africa at CIMMYT and head of wheat rust pathology and molecular genetic in CIMMYT’s Global Wheat program.

An integral part of the program, Acevedo said, was the hands-on training on wheat pathogen survey and sample collection at KALRO.  The scientists utilized the international wheat screening facility at KALRO as a training ground for hot-spot screening for rust diseases resistance.

Daisy Kwamboka, an associate researcher at PlantVillage in Kenya, said the program provided younger scientists with essential knowledge and mentoring.

“I found the practical sessions particularly fascinating, and I can now confidently perform inoculations and rust scoring on my own,” said Kwamboka said, who added that she also learned how to organize experimental designs and the basics of R language for data analysis.

DEWAS research leaders Dave Hodson, Bhavani and Acevedo conducted workshops and presentations along with leading wheat rust experts. Presenters included Robert Park and Davinder Singh from the University of Sydney; Diane Sauders from the John Innes Centre; Clay Sneller from Ohio State University; Pablo Olivera from the University of Minnesota; Cyrus Kimani, Zennah Kosgey and Godwin Macharia from KALRO; Leo Crespo, Susanne Dreisigacker, Keith Gardner, Velu Govindan, Itria Ibba, Arun Joshi, Naeela Qureshi, Pawan Kumar Singh and Paolo Vitale from CIMMYT; Chris Gilligan and Jake Smith from the University of Cambridge; and Jens GrÞnbech Hansen and Mogens S. HovmÞller from the Global Rust Reference Center at Aarhus University.

“I thoroughly enjoyed the knowledge imparted by the invited experts, along with the incredible care they have shown us throughout this wonderful training.”

For participants, the course offered a crucial platform for international collaboration, a strong commitment to knowledge sharing, and its significant contribution to global food security.

“The dedication of the trainers truly brought the training to life, making it incredibly understandable,” said Narain Dhar, research fellow at the Borlaug Institute for South Asia.

The event not only facilitated learning but also fostered connections among scientists from different parts of the world. These newfound connections hold the promise of sparking innovative collaborations and research endeavors that could further advance the field of wheat pathology.

Empowering local mechanics for sustainable machinery maintenance

Smallholder mechanization out scaling depends upon the availability of skilled mechanics who are fully oriented with machinery operation. However, this crucial skillset is often identified as a missing link. In many instances, lack of care or regular checks and the absence of readily available mechanics has led to the failure of mechanization projects in sub-Saharan Africa, with frequent machine breakdowns and equipment left sitting idle long after a project intervention. Across smallholder farming communities, this phenomenon can be seen through the presence of obsolete and abandoned machinery often serving as breeding grounds for birds.

The Feed the Future Zimbabwe Mechanization and Extension Activity, funded by the United States Agency for International Development (USAID), aims to break this vicious cycle by improving the skillset of local mechanics and helping them stay in tune with evolving innovations in farm machinery. Implemented by CIMMYT, this activity targets existing mechanics across ten districts in Zimbabwe, offering specialized maintenance services to providers who own machinery. Through investing in their training, local capacity to troubleshoot, service and repair machinery will increase.

Gaining practical experience

 The program approaches training through full immersion and a deep dive into the individual components of key equipment. Workstations are set up to include a diesel engine—which forms the core of most of the machinery—a two-wheel tractor and post-harvest machines such as the multi-crop thresher, feed-chopper grinder and peanut butter machine.  For most of the participants, the workshop presents them with first-hand experience of handling such machinery.

 Andy Chagudhuma and Tendai Machonesa—from Bikita and Chiredzi, respectively—were among the first ten mechanics to participate in the five-day training. “I learned about all the machines here,” says Chagudhuma, “breaking them apart and fixing them. We worked through different scenarios while perfecting our knowledge on the operation of all the machinery.” With new skills gained, they eagerly await the opportunity to offer their expertise to service providers in their local areas, and a newfound confidence fuels their commitment to providing support through repair and maintenance work.

 However, one remaining challenge is the notable absence of female participants in the training. While the field of mechanics is often male-dominated, the Mechanization Activity seeks to promote a gender-inclusive environment for local mechanics and service providers through awareness meetings and skills training. In the future, more machinery and technical trainings will be targeted specifically towards women as a way to redress this imbalance.

Overall, the benefits of the training echo far beyond the workshop itself. Through the skills acquired, opportunities for additional income generation increase, and the participation of rural youths in mechanization-oriented businesses and a thriving local economy are possible. By empowering local mechanics, the Mechanization Activity not only breathes life into their communities and the machinery sector but also paves the way for one of the project’s key objectives—the establishment of successful and entrepreneurial service providers.

Powered by science, technology, and support systems

The eighth edition of CIMMYT’s seminar series on women’s leadership — Catalysts of Change: Women Leaders in Science — features Usha Barwale Zehr, Director and Chief Technology Officer of Mahyco Private Limited, India. For the last 20 years, Usha has applied new technologies and tools, including biotechnology, to improve the quality and productivity of seeds and agriculture for smallholder farmers in Asia and Africa. Her recent work focuses on sustainability in agriculture and the integration of digital tools into the agricultural value chain to enhance smallholder farmers’ incomes.

During the virtual event, held on November 7, 2023, Usha emphasized the importance of innovative science and technology in agriculture to generate socio-economic impact.

Science and technology are critical catalysts

“The most inspiring aspect of my work is discovering how to help smallholder farmers achieve more from their small and marginal land holdings — those who continue to feed and support us by providing food for large populations in India and around the world,” Usha said, adding that the application of science to this endeavor is critical.

Usha’s thought process has been shaped by her role model — her father.

“His vision and progressive approach in using the latest in science and technology to make a socio-economic impact on the vast majority of our farming population has left a lasting impression on me,” she shared.

Supporting each other to get ahead

“When I think of how we can support each other — and support women in different contexts to become catalysts of change — learning from and helping each other is very important,” Usha said. She pointed out that professionally, we often become so busy that reaching out for help can be a challenge. That is why it is essential to establish structured interactions.

“We need to have formal engagements with colleagues to talk — not just about professional and academic challenges, but also about how we are navigating personal challenges in our professional journeys.” Creating support groups and formal structures to facilitate such engagement is very important, she concluded.

Integrating gender into crop breeding

The Seed Production Technology for Africa (SPTA) project, led by CIMMYT, has been selected by the CGIAR Gender Impact Platform as a successful case study of integrating gender into crop breeding.

The case study, published in Frontiers in Sociology, is one of fourteen that the CGIAR Genetic Innovation Gender strategy is drawing on to showcase lessons learned from practical experience. These case studies form a critical part of the efforts to pursue gender responsive or gender-intentional breeding and explore how these can inform larger breeding pipelines.

Maize is widely grown by both women and men in Africa. Evidence of gender-differentiated preferences for maize varieties remains inconclusive; however, there is evidence of gendered differences in management practices. Hybrids produced using SPTA segregate 1:1 for pollen producing and non-pollen producing plants referred to as 50% non-pollen producing (FNP) varieties. Previous research showed FNP offered a yield benefit under low input conditions. In the early stage of its inception, the project quickly recognized the potential implications of hybrids produced using SPTA for women and other resource-constrained smallholders in Africa.

Understanding gender-based differences

From the start, the SPTA team conducted a gender review that underscored the fact that women in the region often use less fertilizer than men, a challenge that is further compounded by cultivation of smaller plots and lower quality soils. This review led the breeding team to explicitly target women and resource-poor farmers with an ambition to increase yields on women’s fields. From here henceforth, SPTA made it a priority to understand gender-based differences in performance and preference for new FNP maize varieties. This process involved ensuring both women and men farmers host trials to evaluate and attest to the performance of the FNP hybrids.

But these efforts were not without challenges. The team also found significant gender differences, particularly among women farmers in crop management practices and between farmers’ stated preferences during participatory varietal selection exercises and the varieties they used at home. This suggested that initial on-farm evaluations were not adequate for predicting real world demand for varieties. Moving forward, the evaluation strategy of SPTA evolved to enable variety evaluations under farmers’ preferred management practices.

The success of the SPTA team in ensuring that gender considerations were strongly embedded into the breeding program is attributed to strong collaboration across disciplines that included social scientists and gender researchers working closely with breeders, allocating funding to allow exploration, testing of gender topics and responsive variety evaluation tools and strong buy-in from leadership and donors. As the SPTA case highlights, there is value in starting small, building productive partnerships and collaborating to pilot and develop proof of concept for new models.

Say yes, and figure out what gives you energy

CIMMYT hosted the 6th instalment of its online seminar series — Catalysts of Change: Women Leaders in Science — featuring Diane Holdorf, executive vice president and a member of the Senior Management Team at the World Business Council for Sustainable Development (WBCSD).

Drawing on varied experiences from a diverse career in sustainability, Holdorf used her talk to emphasize the importance of saying ‘yes’ in the face of big changes, identifying what energizes you, being present at home and at work, and supporting others to succeed with their objectives.

Translating science

As the daughter of a geologist, Holdorf spent much of her childhood outside looking at rocks, an experience she credits with giving her an affinity for nature. “I found it was a way that really connected me and grounded me in my surroundings. What are we looking at? What are we looking for? What’s in the patterns and shapes of what we see?”

Holdorf talks about her childhood. (Photo: CIMMYT)

After deciding that she didn’t want to go into science, Holdorf opted to study public communications at university and was promptly recruited by an advertising agency upon graduating. “It was the first time that something big came up where I just said: ‘Yes. Yes, I’ll try it. Why not?’ And that theme of saying yes in the face of these big changes is one that’s proven to be incredibly helpful.”

However, having moved halfway across the country for the job, Holdorf quickly found that she disliked the role. “It was a really important lesson in learning what I didn’t value and what I didn’t want to do,” she said. “That came really early in my career, the idea that I needed to be way clearer in my convictions. What matters to me? What do I want to be working in? And that led me to go into environmental consulting.”

“Maybe not an obvious path, but my dad had been an environmental consultant,” she explained. “So, in some ways I’d fallen back into something that was a bit familiar, but that I could make my own.”

In this new role, Holdorf found she could put her communications skills to use in a way she found energizing, translating scientific and technical solutions into words that clients could understand or that project managers could frame and create workplans around. “Without realizing it, it grew into this role of being the translator between ‘what does the science and engineering tell us’ and ‘what are the business solutions that we need to use that information to solve for.’”

“I’ve learned that what really drives me and what gives me the most energy is working together with people to create the biggest impact and change we possibly can,” she explained. “What motivates me the most is trying to drive action on these extremely urgent challenges of climate, nature, equity, and in our food systems.”

Helping others succeed

“Leading with clear objectives and clear boundaries is really important,” said Holdorf. “And I don’t mean that in a rigid way. I mean knowing what I can accept when engaging with others, and what I will not go past. What areas of acceptance are needed for my integrity in a role.”

She noted that one of the things that has been particularly useful throughout her career — especially during the first 15 years, when she was often the only woman in the room — are the male colleagues who stood up for her, coached her and provided feedback on her work.

“And I listened hard,” she explained. “I asked for that feedback and really worked to incorporate it because I could tell that what they were telling me was meant to help make my role easier. That was a hugely valuable lesson because it taught me that if it was that important for me, it meant that I could in fact play that same role for others.”

As a result, she now encourages not only learning how to seek out mentorship, but also reflecting at every stage of a career, identifying opportunities to mentor others, and creating a stream of development and gift-giving.

“How do we ensure that our work helps others to succeed?” she asked. “Because often when we’re working in these spaces, we can only achieve our objectives by leading with and influencing others. It’s not very often that we have full control. But learning how our work can help others deliver on the goals that they’ve been tasked with actually creates totally different types of breakthroughs.”

Holdorf’s presentation was followed by a Q&A session led by Pauline Muindi, research support specialist at CIMMYT.

India transforms wheat for the world

In 2023, India reached a record wheat harvest of over 110 million tons. A partnership between CIMMYT and the Indian Institute of Wheat and Barley Research (IIWBR) now allows farmers to pre-order advanced wheat varieties, transforming the nation’s agriculture.

The need to consider biological actors as an influence when studying market agencies

How the living shapes markets: accounting for the action of biological entities in market agencing. Authors: Quentin Chance, Frédéric Goulet and Ronan Le Velly

This article uses research into the organic food market in France to show that biological factors can play an important part in influencing the structure and organization of markets. The authors use this to point out that while many studies of market agencing discuss in detail the role played by social and material agents, biological agents should be an equally important part of such research.

Over the last four decades, there has been considerable research into Actor-Network Theory (ANT), which looks at the effect of various agents on markets. However, in the majority of cases, the agents discussed have been material (for example, shopping trolleys) or social (human habits or economic motives). The research which forms the basis of this article was originally carried out as a study of how French organic-produce collectives tried to influence markets to suit their needs and ideals. On reviewing the data, it appeared to the authors that there were additional agents affecting their marketing, which derived from biological factors. Unlike the material and social agents, farmers were only able to control these biological factors with great difficulty, if at all. For example, the inability to use chemical inputs on crops meant that crop rotation over a multi-year period was essential; however, wholesalers’ traditional structures expected a farmer to supply the same produce in the same quantity year after year. In cases such as this, altered supply chain arrangements needed to be negotiated between the suppliers and the wholesalers.

The authors made four sets of observations showing the market-shaping effect of biological agents.

  • Measures taken by established organic farmers to avoid price competition from new market entrants — the well-established farmers had chosen to start growing crops which required more expertise, time or equipment (such as Belgian endives or onions), rather than less complex standard crops such as potatoes.
  • Biological processes which necessitate altering the traditional market production and supply structures — for example, the need for crop rotation as mentioned above.
  • Natural agents will affect crop yields and introduce variability in quality and quantity, which the market needs to allow for. The authors give examples of pests, viral infections and weather as agents that affect all farming, but in the case of organic farming are particularly troublesome.
  • After harvest, produce will naturally experience ripening/aging, and then degradation in quality. Standard industrial ways of controlling these biological processes utilize methods and agents that are unacceptable or even harmful when dealing with organic produce, for instance, spraying with chemicals.

Following these observations, the authors make a series of propositions and suggest research questions which could result from them, for instance:

  • How does the action of biological entities affect the establishment of market norms/the way prices are set?
  • How do representations of the market take account of biological processes?

In conclusion, the authors demonstrate how the effect of biological agents on markets is already inextricably intertwined with the effects of material and social agents. Future research, to be truly comprehensive, needs to look in equal depth at all other possible influences on the market.

CIMMYT researcher receives Heroes Award

Maria Itria Ibba, a scientist at CIMMYT, received the inaugural Heroes Award from the Foundation for Innovation in Healthy Food. She received the award on October 29 at the ASA-CSSA-SSSA International Annual Meeting in St. Louis, Missouri, U.S.

Ibba, head of CIMMYT’s Wheat Chemistry and Quality Laboratory, received the honor in recognition of her outstanding leadership in launching the foundation’s Coalition for Grain Fiber initiative.

Together with her team at CIMMYT, Ibba works on improving the processing and nutritional quality of the bread and durum wheat lines derived from the CIMMYT spring wheat breeding programs. The research they conduct combines genetics and cereal chemistry, and one of the main focuses is to improve wheat grain dietary fiber. This effort begins with the development of efficient screening methods and the identification of germplasm with unique dietary fiber profiles.

The coalition seeks to improve the nutrition in staple foods without impacting their taste, mouthfeel or consumer price. It is simultaneously dedicated to establishing profit incentives for farmers and other food suppliers that enhance public health by delivering increased nutrient foods.

According to the coalition, improvements in the nutritional content of white and whole wheat flour may ultimately save thousands of lives and billions of healthcare U.S. dollars globally.

“Most people across the world do not consume enough dietary fiber, which is essential in the fight against various diseases,” says Ibba. “Increasing the dietary fiber content of a staple crop like wheat could have a significant positive impact on the health of wheat consumers. Our goal is to increase dietary fiber intake through the consumption of wheat products with greater fiber content.”

Plant breeders, food scientists, nutrition/health scientists and economists are partnering with the coalition to transform the food industry. They support non-GMO (not genetically modified organisms) approaches to increasing naturally occurring dietary fiber in grains.

Over 50 public and private-sector laboratory leaders in three countries and 23 U.S. states have engaged with the coalition, including from CIMMYT, Rothamsted Research, University of Nebraska, Lincoln, University of California, Davis, Cornell University and Bayer Crop Science.

The Nebraska Wheat Board provided support for the efforts of the foundation and the coalition.

“I feel humbled to have received the Heroes Award,” says Ibba. “I know that this award not only represents the work I have been doing, but also all the hard work that my team and my organization have been doing for several years.”

New partnership announced to protect Gorongosa National Park in Mozambique by improving agricultural livelihoods and crop systems

A collaboration scheme launched between the Gorongosa Restoration Project (GRP) and CIMMYT seeks to improve climate resilience, food security and nutrition in Mozambique’s Gorongosa National Park by facilitating the adoption of sustainable practices and giving local farmers access to formal markets and improved value chains.

The partner organizations aim to develop more resilient agrifood systems that contribute to conserve resources and improve the livelihoods of farmers inhabiting the protected area in Mozambique’s Sofala Province.

“Our primary objective is to establish an evidence-based, scalable and replicable model for developing sustainable and resilient agrifood systems in Mozambique that enhance food and nutrition security and climate resilience of local farmers and communities,” said Gregory C. Carr, GRP President.

The parties will explore collaboration opportunities to give local farmers access to drought tolerant and disease resistant varieties and improved seeds by building capacities of local seed systems.

“We are very excited to contribute to protect Gorongosa National Park by restoring soil health, accelerating a transition to resilience and sustainability and improving, as a result, the yields and living standards of local farming communities,” said Bram Govaerts, Director General at CIMMYT.

The new projects will also aim to promote agriculture conservation-based intensification practices that will increase yields sustainably and limit the expansion of the agricultural frontier in the buffer zone neighboring the protected area.

“If you bring two world class organizations together and create critical mass, it is possible to succeed and show that agriculture is not the enemy of biodiversity,” said the U.S. Special Envoy for Global Food Security, Cary Fowler.
