Over the next 10 years, maize is due to become the most widely grown and traded crop globally and is already the cereal with the highest production volume. Its versatility offers multiple purposes – as a livestock feed in both developed and developing economies, as a key component of human diets in several low- and middle-income countries in sub-Saharan Africa, Latin America and Asia, and for an array of non-food uses worldwide.
The study primarily focused on the Global South, where intensive work is being done to transform the agrifood systems in which maize plays a key role. Through scientific advancements over time, maize yields have increased, although heterogeneously, while the area under cultivation of maize has also expanded due to sharply growing demand.
Research determined that this transformation offers opportunities for investment in maize research and development (R&D) to determine ways that production and productivity can be significantly improved without expanding maize area or creating negative impacts on the environment.
“Agriculture systems are sensitive to climate change because they are dependent on stable, long-term conditions to determine productivity, quality and yields,” said Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT) and the conference’s keynote speaker. “Farmers are struggling to cope with climate risks and their ability to meet rising global food demands.”
Breeding maize and wheat with traits resistant to the consequences of climate change, such as flooding, drought, and heat, moving growing areas to amenable climates, and promoting soil health and biodiversity were all proposed as solutions to address the challenges highlighted by Govaerts.

One of the biggest challenges facing the world today is how to balance a healthy diet for humans with agricultural production that is good for the environment. At the International Maize and Wheat Improvement Center (CIMMYT), scientists work closely with farmers to achieve these aims and contribute towards food security, as well as improving their livelihoods and nutrition.
Govaerts explored the sensitivity of agricultural systems to the impacts of climate change, which in turn affects farmers’ ability to successfully produce crops and their capacity to meet rising global demand for food. However, agriculture itself is not immune from contributing towards climate change, currently accounting for 24% of greenhouse gas (GHG) emissions.
The effects of climate change are not the only pressure on agrifood systems, with other system shocks such as COVID-19 and conflict causing disruption to production and yields, prices, and supply chains, said Govaerts. For example, the current Ukraine crisis, which has heavily affected wheat imports and exports, underscores the need for long-term solutions to stabilize global food security. The encroaching cost of living crisis is adding further challenges to an already delicate situation, and hunger is predicted to increase across the Global South.
Investing in solutions
Research and development (R&D) has an essential role to play in addressing this crisis. Evidence shows that for every $1 USD invested in anticipatory action to safeguard lives and livelihoods, up to $7 USD can be saved by avoiding losses in disaster-affected communities. Simply put, proactive investment in agricultural science will save money in the long run by solving problems before they reach critical point.
CIMMYT’s R&D projects focus on extensive research on climate change adaptation and mitigation in maize and wheat-based production systems, helping smallholder farmers adapt to climate shocks and to raise and maintain yields in profitable and sustainable ways, and on capacity building for stakeholders in the development and application of new technologies.
Scientists are also harnessing the power of genebanks and breeding, focusing on safeguarding, characterization, and use of biodiversity to identify characteristics of seeds for genetic gain, adaptation to climate change, and better nutritional quality. This means farmers can access more and better seeds that respond to agrifood needs.
These innovations are only as effective as their level of adoption, which is why CIMMYT works closely with actors at all levels of agrifood systems.
Climate science at work in Africa
Govaerts shared examples of CIMMYT’s climate change adaptation and mitigation work include the introduction of drought-tolerant maize in Zimbabwe, which yielded more than 0.6 t/ha more than previous varieties. This equates to $240 USD more income per hectare, which provides nine months’ worth of additional food security at no extra cost.
In Malawi, drought-tolerant maize varieties planted under conservation agriculture yielded 66% more than non-tolerant varieties planted under conventional tillage. Farmers harvested more maize while spending on average 35-45 fewer days working in the field.
There is also an increase in popularity for stress-tolerant wheat varieties in Ethiopia, such as Danda’a, Kakaba, Kingbird and Pavon 76.
Scientists have also combined tropical fall armyworm (FAW)-resistant maize germplasm, from Mexico, with elite stress resilient germplasm developed in sub-Saharan Africa to successfully breed three FAW-tolerant elite maize hybrids. This is addressing the serious threat of FAW to maize production in eastern and southern Africa.
Transformation through partnership working
Following an Integrated Agrifood Systems Approach (IASA) has given CIMMYT significant edge by building effective partnerships with the public and private sector. Collaboration on responsible sourcing with Kellogg’s and Grupo Bimbo, as well as a new three-year partnership with Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and Grupo Modelo to encourage water-conserving farming practices, will contribute to a one-system approach.
More than 18 million farmers worldwide benefit through CIMMYT’s improved maize and wheat system farming practices. With so much at stake for the entire world, CIMMYT has no plans to stop now.
Events of the past year have underscored the correlation of food supply chains, and weaknesses that need to be addressed. Tackling threats to global food security caused by COVID-19, conflict, and climate change require joint action and long-term commitments, with approaches based on partnerships, collaborative research and information sharing, and involvement from all actors within agrifood systems.
These topics and potential solutions were integral to the 2022 Norman E. Borlaug International Dialogue, hosted between October 18-20, 2022. With a theme of Feeding a Fragile World and overcoming shocks to the global food system, seminars and workshops explored scalable solutions for adaptation and mitigation to limit global warming and meet the UN Sustainable Development Goals (SDGs).
Ag4Peace is built on the understanding that without peace there is no food, and without food there is no peace. Conflicts and violence severely disrupt agricultural processes and limit access to food, which in turn forces people to take increasingly perilous actions as they attempt to secure their lives and those of their families. High food prices and hunger cause instability, migration, and civil unrest as people become more desperate.
Using a collaborative approach, partners will design holistic strategies that encompass the multi-faceted nature of agrifood systems and their interconnections with nature, nutrition, and livelihoods. This requires broad-based collaborations, so the Ag4Peace partners welcome other institutions, private sector, and non-governmental organizations that share their aspirations to join them.
Partners are co-constructing the Cross-Sector Collaboration to Advance Resilient Equitable Agrifood Systems (CC-AREAS), the first operational plan for the platform. This is a 10-year proof-of-concept program that applies a holistic, systems approach to achieve resilient agrifood systems and accelerate development of the circular bioeconomy in five low- and middle-income countries (LMICs) that are increasingly exposed to food security risks due to climate change and reliance on imported staple foods.
They will support national efforts to upgrade agrifood systems, adopt regenerative agriculture and climate-smart strategies, expand the circular bioeconomy, and achieve nutrition and food security goals.
In all aspects of the initiative (science, planning, implementation, and evaluation), participation priority will be given to small-scale farmers, women, and socially diverse groups, which will maximize positive outcomes and ensure inclusivity.
Benefits for farmers, communities, value chain participants, consumers, and ecosystems will be demonstrated throughout to encourage adoption and continued use of improved technologies and practices and demonstrate effectiveness.
Partner support for Ag4Peace
After the concept was introduced by Bram Govaerts, Director General of CIMMYT and recipient of the 2014 Norman Borlaug Award for Field Research and Application, a roundtable discussion with a diverse panel of experts began.
Speakers included Manuel Otero, Director General of the Inter-American Institute for Cooperation on Agriculture (IICA), Hon. Sharon E. Burke, Global Fellow of Environmental Change and Security Program at the Wilson Center, Per Pinstrup-Anderson, Professor and World Food Prize Laureate, and Alice Ruhweza, Africa Regional Director of the World Wildlife Fund (WWF).
Moderated by Margaret Bath, Chair of CIMMYT Board of Trustees, the panelists conveyed Ag4Peace’s aims of building productive, sustainable, and resilient agrifood systems, improving livelihoods for small-scale producers and other value chain actors, and deliver nutritious, affordable diets.
“Hunger is part of the picture of conflict,” explained Burke. “These strapped communities are often competing for resources with each other, within their own boundaries, and sometimes food is a weapon in these places, just as destructive as a bomb or a gun. Without food there is no peace, in the near or the long-term.”
Trade-offs versus win-wins
Pinstrup-Anderson ruminated on the importance of win-wins, which are solutions that work for supporting human health and protecting our natural environment without sacrificing results in one area for results in another. “We do not have to give up improving nutrition just to save the climate or save the earth – we can do both,” he said.
The significance of strong partnerships arose multiple times, such as when Otero explained, “It is not a matter of working just with the agriculture ministers but also with other ministers – foreign affairs, social development, environmental – because agriculture is a sector that crosses across all these institutions.”
Ruhweza explored whether threats to food security, such as COVID-19, conflict, and climate change, can also bring opportunities. “The right action on food systems can also accelerate the delivery of all our goals on climate and nature,” she said. “WWF is looking forward to partnering with this initiative.”
Final remarks from Julie Borlaug, President of the Norman Borlaug Foundation, where the platform will be housed, reiterated a call for more partners to join the coalition. “This is a learning lesson as we go. We will iterate over and over until we get it right, so we need all of you to be involved in that,” said Borlaug. “Join us as we move forward but let us know as we’re going sideways.”
Govindaraj received the award for his leadership in mainstreaming biofortified crops, particularly high-yielding, high-iron, and high-zinc pearl millet varieties. This work has contributed to improved nutrition for thousands of farmers and their communities in India and Africa, and estimates show that, by 2024, more than 9 million people in India will be consuming iron- and zinc-rich pearl, benefiting from improved nutrition.

Kazakhstan is the ninth largest country in the world and the fourteenth largest producer of wheat; in 2021 alone, the country produced 14.3 million tons (t) of wheat on 12.1 million hectares (ha). Despite this impressive figure, wheat yield in the country falls below average at 1172.5 t/ha compared to 3474.4 t/ha globally.
Research into wheat diseases in Kazakhstan has primarily revolved around airborne fungal foliar diseases, such as stem rust, leaf rust and stripe rust, which can be devastating for farmers and their crops. However, the effects of fungi relating to wheat root and crown root were yet to be examined – these diseases affect yields, stands and grain quality due to infections that cause damping-off, blight, necrosis, and dry rotting.
Using plant samples taken during the 2019 growing season, scientists from the International Maize and Wheat Improvement Center (CIMMYT) conducted a quantitative survey to determine the distribution of this fungi. Using morphological and molecular tools on 1,221 samples from 65 sites across the central, eastern, and southeastern region, scientists found that Bipolarissorokiniana and Fusariumacuminatum were the most predominant fungal species isolated.
In total, 74 isolates from 16 species were tested, revealing that F. culmorum and F. pseudograminearum, B. sorokinaiana, Fusarium sp., R. solani, F. redolens, C. spicifera, C. inaequalis, and N. orvzae were virulent fungi.
Results show the diverse spectrum of pathogenic fungal species linked to wheat crown and root rot in Kazakhstan and is highly likely to be the first report from the country on the presence of F. seudograminearum, Fusarium sp., C. spicifera, and C. inaequalis.
With this new data, scientists can develop mitigations to prevent crop loss and improve wheat yield across Kazakhstan.

The paired challenges of population growth and climate change have put smallholder farmers in Zambia in a squeeze. In the Southern Province, the center of agricultural production for the nation, smallholder dairy farmers struggle to increase their production of fodder to commercially viable levels in the face of a long dry season that climate change is intensifying.
Smallholder farmers looking to support their families, enhance the local food supply, and sustain economic growth in their areas are at a distinct disadvantage because agriculture in Zambia is dominated by massive commercial operations with plentiful capital, large tracts of land, and expensive machinery, with most of their output marked for export.
The International Maize and Wheat Improvement Center (CIMMYT) is partnering with the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the University of Hohenheim to identify key barriers and sustainable pathways to smallholder farmer success through a mechanization working group. This work is being carried out through the global initiative One World No Hunger, which launched Green Innovation Centers for the Agriculture and Food Sector (GIC) in 15 member countries in 2014.
“Mechanization is a critical aspect of responding to these problems and the core business of the GIC is to develop knowledge,” said Chimuka Mulowa, a GIC cooperative development advisor based in Choma, Zambia. “Our efforts provide training to smallholder farmers with a focus on adaptive mechanization as a critical ingredient in a holistic approach. Projects in the past have purchased equipment, but we integrate knowledge with existing infrastructure.”

In Zambia, the GIC works with 22 cooperatives to reach 10,000 small-scale farmers with training sessions on fencing land to grow grass, climate smart breeding, irrigation, and more. The GIC has reached their training goal, but implementation of new practices has been more difficult, with only about half the farmers adopting what they have learned so far.
To better understand the challenges smallholder farmers face in Zambia, Mulowa and the GIC partnered with researcher Vuyo Maphango, who was completing his master’s degree in agricultural economics at the University of Hohenheim under the supervision of Lennart Woltering, a senior scientist at CIMMYT. Woltering developed a tool called Scaling Scan which analyzes barriers to growth for successful innovations in the pilot stage and brings focus to key ingredients for expansion.
Mulowa and Maphango used Scaling Scan to assess the progress of the GIC efforts in Zambia. As they expected, for smallholder farmers trying to get into commercial fodder production, financing was a challenge. At $35,000 USD for a machinery like hay balers used once per year, it can take a farmer up to a decade to recoup such an investment. But Scaling Scan also identified surprising challenges, such as a lack of collaboration and uneven dissemination of knowledge and skills.
“There was a lot of progress coming out of the Scaling Scan process,” Maphango said. “Growing the cooperatives of farmers is a critical GIC focus now, and this helps with the finance issues as well. Where farmers can’t afford to buy or develop high-quality seed, they can come together, share which seeds are working best for them, and help each other adopt best practices. Staying close as a cooperative also gives farmers stronger bargaining power with the ability to pool together finances.”
More affordable equipment will also help. Smaller, less expensive choppers and chuff cutters ($1500-2000 USD) are already available for silage production, but there is not a well-established tradition of employing silage production in Zambia, and farmers there have struggled to adopt it. Similar machines are making their way onto the market for fodder production and will require farmers to develop a new set of technical skills.
Mulowa and Maphango are also rethinking approaches to training. As an incentive, non-government organizations (NGOs) often pay participants for their time when they attend training sessions, but government ministries can’t sustain this practice beyond the end of a project due to lack of funding. For a deeper level of skill and knowledge development, GIC wants to help farmers see the benefit of training as providing its own incentive–continuing professional education will pay off, both in terms of better agricultural and business practices, and better financial outcomes. The key to this transition is results. When farmers see their yield improving because of skills and practices they developed in training, they will be hungry for more.
Success, for Zambian smallholders, is a door that is opening slowly but surely. “Early adopters are making progress,” Maphango said. “Some are growing their own grass, others are fencing their land and developing irrigation.” As these practices take root, and farmers share victories with cooperative members; the value of ongoing training becomes clear, and the door may open further for others to walk through.

The two-wheel tractor has been a life changer for Ranganai Muzorori.
At a recent seed and mechanization fair in Zimbabwe, the maize farmer, who purchased the tractor on a lease-to-own basis, said he now enjoys bigger earnings.
Not only has he realized a significant change in his income due to the tractor, he no longer has to struggle to shell maize because he now has access to a machine that strips the corn off the cob.
In a day I can shell about 10 tons, which is helpful for saving precious time, Muzorori said.
Land preparation is also less arduous. “We no longer rely on animal draft power or our own manual labor, but the tractor,” he added.
Due to the versatility of the tractor, which has multiple attachments depending on the task that needs to be done, he has also secured a formal annual contract with Great Zimbabwe Hotel in the southeastern city of Masvingo. He attaches a trailer to the tractor to collect garbage and transport it to the dump, diversifying his income beyond conventional on-farm earnings.
Before the International Maize and Wheat Improvement Center (CIMMYT), in partnership with Zimbabwe’s government extension arm Agritex (Department of Agricultural, Technical and Extension Services), introduced low-cost tractors and small engine-operated farm machinery, such innovations were just a dream for many farmers in Zimbabwe who could not afford to pay $30,000 USD.
“We need to move with the times, the days of relying on either draft power or manual labor should be a thing of the past,” said Caleb Mnkandla, an Agritex supervisor. “With more exposure forums for farmers like this, we can accelerate the adoption of mechanized agriculture even at a smallholder farmer level.”
Improved mechanized tools are also now available to smallholder farmers.
Increased efficiency lightens load
A recent surge of January and tickborne diseases, which affect livestock, added to difficulties faced by many communal farmers due to draft-power shortages during land preparation and planting seasons.
This has translated to reduced yields for many farmers as the timing and efficiency of land preparation and planting has a direct impact on crop yields.
Other farmers in Masvingo are also seeing the transformative capabilities of such mechanization, as reflected in testimonials during the R4 Rural Resilience and ZAMBUKO seed and mechanization fair held in October.
The project – funded by the United States Agency for International Development (USAID), the Swiss Agency for Development and Cooperation (SDC), and the World Food Programme (WFP) – is intended to reduce the arduous manual labor associated with the use of hand operated ploughs and tools.
“Smallholder production systems in Africa have been heavily comprised of intense drudgery which makes farming less attractive for youth and difficult for women,” said Abdul Matin, a lead scientist with CIMMYT. “The new mechanization technologies we are bringing in are meant to reduce drudgery and cost, and add increased efficiencies to smallholder farmer operations.”

Greater accessibility through financing
In a joint collaboration, Agritex and CIMMYT provide an innovative financial scheme under which service providers pay a commitment fee of $500 USD to access the machinery. They then receive a grace period of four months and pay instalments of $100 USD a month for 20 months. The project covers half of the machinery cost as risk sharing.
So far, there are 34 service providers participating in Masvingo, offering mechanization services to smallholder farming communities for a fee. The project is a scalable pilot for the rest of the country.
The service provider model puts the focus on the asset owners, who not only enjoy the benefits of the mechanization, but also offer services to surrounding farming communities which causes exponential impact, Matin said.
The package of services farmers have been accessing include tillage, transportation, shelling and threshing services.
Tractors can be used for transportation year round, providing steady income for service providers.
The fair provides a platform to demonstrate and showcase the impact of the new technology to farmers, said Pamela Chirwa, project coordinator for CIMMYT’s Global Maize Program in the Southern Africa Regional Office located in Zimbabwe, who coordinated the event.
“We need to continuously expose farmers to other farmers who have moved on to mechanized production,” she said. “Such farmer-to-farmer extension makes it easier for others to adopt technology as they relate to each other better.”
“Adopting improved maize seed varieties alongside two-wheel tractors and other machinery will also improve capacity and potential earnings,” said Christian Thierfelder, a principal scientist with CIMMYT, addressing farmers in Masvingo, emphasizing that for conservation agriculture, mechanized equipment is a labor-saving technology.

The CGIARWomen in Research and Science (WIRES) employee-led resource group recently had a virtual engagement to discuss the progress and new happenings in the group. The meeting, themed “Connecting and Mentoring, What’s new with WIRES!” was held on October 24.
Giving the opening remarks, The Alliance of Bioversity International and CIAT Knowledge Sharing Specialist Arwen Bailey stated that the group was launched in July 2020 to empower and increase the visibility of women research and science professionals across CGIAR.
Explaining the vision and mission of the group, Das stated that WIRES aims to provide tools and knowledge that support professional development. She added that this would create visibility for CGIAR women in science and research so their voices are heard and their contributions recognized. “We are an open community that accommodates both men and women who are willing to support the vision of WIRES,” she said.

Discussing her reason for sponsoring WIRES, CGIAR Executive Managing Director Claudia Sadoff said she admires the efforts and engagement of the team in supporting women despite having other personal life activities. She added that the increase in the percentage of women scientists calls for more effort to train and empower these women. “Thanks for allowing me to be your sponsor,” she said. International Livestock Research Institute (ILRI) Director General Jimmy Smith, also a sponsor, stated that his motivation to join the cause stems from his experience raising daughters.
Highlighting how intending volunteers can support WIRES, Das spoke on mentorship as a promising strategy to advance Gender, Diversity and Inclusion (GDI) in the workplace as it offers access and advocacy for women. Explaining the criteria for engagement, she stated that a mentor must be passionate about advancing GDI, while the mentee must be a middle to senior-level career woman researcher/scientist with an appetite to learn. “Registration for the program will begin in November, and the program will kick off in December. Interested mentors and mentees who meet the criteria can register and be trained,” she said.
Other new WIRES initiatives coming up before the end of 2022 include “Random coffee,” where members can schedule to meet physically or virtually to build a vibrant relationship and network, and “Focus groups” for discussions that will ensure continuous improvement for WIRES.
Closing out the meeting, CGIAR Global Director of People and Culture, Fiona Bourdin-Farrell, summarized ways volunteers can help to advance women in science and research in CGIAR. She mentioned that it starts with joining the WIRES team, being a part of the mentoring program, engaging in the random coffee pilot, and joining focus groups. “You can contribute to the information in the newsletter. You can also register as both mentor and mentee as long as you meet the criteria,” she concluded.
When the Norwegian Red Cross hired Kristian Wengen and his consulting firm Tinkr to launch a “Scaling for Success” initiative, he found himself at a crossroads. From international aid projects aiming to address the UN Sustainable Development Goals (SDGs) to private companies seeking to expand their market, everyone was talking about the challenges of scaling up – expanding and sustaining successful programs to reach a greater number of people – but there were few clear paths to solutions.

The Scaling Scan has solutions to offer
But when Wengen came across a project using a tool called the Scaling Scan that identifies and analyzes 10 critical elements for assessing the scalability of any pilot project, he knew he had found a way forward. He was excited, but also worried because the project using the Scaling Scan had concluded.
Concerned he would lose access to the best tool he had found by far, Wengen connected with Lennart Woltering, who created the Scaling Scan for the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with a Dutch-supported project on private-public partnerships called the PPPLab. Woltering and Wengen began a dialogue regarding repurposing the Scaling Scan for Wengen’s context.
“What I like about the Scaling Scan is that it works on a very detailed level to produce systemic results,” said Wengen. “It brings a simple approach to the complex problems of scalability, which allow organizations to achieve efficient solutions, regardless of their geographic or demographic context.”
The Scaling Scan focuses attention on discrete components – from finance and business cases to technology and skills – which are necessary to successfully scale an innovation. But it also spurs insight into how each of these necessary ingredients complement each other as a project prepares to successfully transition, reproduce, and expand.
Wengen believes the most effective work of the Scaling Scan happens in team conversations, and it helps deliver clear feedback that can form the basis of discussions that go straight to the heart of the matter. While the challenges of scaling an innovation are complex, the Scaling Scan cuts through the noise and focuses attention on solving the most important problems, whether related to leadership, collaboration, or public sector governance.
Scaling the Scaling Scan
In their conversations, Wengen and Woltering identified opportunities for improving the Scaling Scan. For example, Wengen is building a digitized, web-based version that, like the original Scaling Scan, will be freely available. He calls it a scorecard, a smaller version which capitalizes on the ability of the Scan to promote productive dialogue that moves a project forward. “I am thrilled to help broaden the reach of the Scaling Scan, as making it available for a much wider audience will democratize innovation,” Wengen said.
“Kristian’s adaptations are exactly how I designed the Scaling Scan to work,” said Woltering. “I wanted it to be straightforward enough to be useful across a broad range of business and development applications and flexible enough to be tailored to the specific needs of a particular region, culture, or marketplace.” Seeing how Wengen has utilized the Scaling Scan across a variety of markets has spurred Wennart to develop the Scaling Scan website, where other interested practitioners can download the tool and share their own innovations. “The Scaling Scan truly has utility across the broadest geographies and socioeconomic ranges,” said Wennart.
Wengen is hoping his scaling scorecard will help drive success in a new collaboration he is undertaking with Innovation Norway, a state-owned organization that helps Norwegian businesses grow and export promising products and services. Wengen believes his scorecard will add immense value to a diverse set of projects ranging from business management software helping bakeries reduce waste and increase profits to zero-carbon ocean-going ships and virtual medical training systems.
This kind of transfer and growth shows that even the Scaling Scan itself can be scaled up from the tropics to the Arctic Circle, and Woltering can’t wait to see where the next successful adaptation will spring up.
Since the outbreak of FAW was reported in 2016, maize yields have dropped by between 30-50 percent, increasing the country’s challenges for food security.
Prasanna Boddupalli, Director of the Global Maize Program at CIMMYT, said, ″We want farmers to dissociate from application of synthetic toxic pesticides and chemicals but revert to use of combined approaches like use of resistant varieties, bio-pesticides and related biological control methods that are environmentally friendly.”
Preliminary assessment of the viability of naturally tolerant maize varieties from Mexico suggests that at least two or three resistant varieties may be approved after certification from the regulator.

With rising demand for food, it is more critical than ever to address the challenge of crop losses due to pests and diseases. Current limited understanding of the extent of the problem prevents the advancement and implementation of plant health solutions. Global scientific collaboration is integral to ensure policy recommendations are well-informed by robust evidence and therefore more likely to succeed in the long-term.
The issue of global burden of crop loss closely correlates with the objectives of the One CGIAR Plant Health Initiative, which aims to prevent and manage major pest and disease outbreaks through the development and deployment of inclusive innovations and by building effective national, regional, and global networks. The Initiative, which is being led by the International Maize and Wheat Improvement Center (CIMMYT), will support low- and middle-income countries in Africa, Asia, and Latin America to reduce crop losses due to pests and diseases, and improve food security and livelihoods for smallholder farmers.
Data-driven approaches
The Global Burden of Crop Loss project, which is run by the Centre for Agriculture and Bioscience International (CABI), is working to ensure that there is accurate data on the challenges posed by plant pests and diseases. Questions to understand include where crop losses are the highest, the causes behind these losses, and how best these they can be addressed.
Cambria Finegold, Global Director, Digital Development, CABI said, “If you are not measuring crop loss well, then you don’t know if the extraordinary $25.8 billion spent annually on agricultural research and development is working, or if we are spending it in the right ways.”
Research by the Plant Health Initiative will play a significant role in collecting and disseminating data on some major pests and diseases, which can guide scientists on which areas to prioritize, thereby contributing to an impactful research agenda.
Once data is gathered, CABI aims to inform decision-making for actors at the top levels of the plant health system and ensure that appropriate action is taken to safeguard global food security with the limited resources available.

Establishing global networks
The value of a data-driven approach was emphasized at a session organized by the Global Burden of Crop Loss on October 14 exploring evidence-based systems to tackle food security. This session was a side event of the UN Food and Agriculture Organization (FAO) Science and Innovation Forum, which this year focused on highlighting the centrality of science, technology and innovations for agrifood systems transformation.
Prasanna Boddupalli, One CGIAR Plant Health Initiative Lead and Director of CIMMYT’s Global Maize Program, explained how the Initiative will bridge knowledge gaps, build risk assessment and rapid response capability, improve integrated pest and disease management, design and deploy tools to prevent contamination of food chains, and promote gender-equitable and socially inclusive innovations for plant health.
With six devastating plant epidemics in Africa alone during the last decade and an increased number of climate change-induced droughts and floods, Boddupalli proposed a revitalized strategy using the objectives of the Plant Health Initiative.
Built on a foundation of partnerships, there are more than 80 national, regional, and international organizations involved in the Initiative across 40 countries in the Global South, in addition to the CGIAR research centers. Through this rapidly expanding collaboration, the focus will be on establishing regional diagnostic and surveillance networks and implementing Integrated Pest Management (IPM) and integrated mycotoxin management.
To address the need for evidence-based policy recommendations, Boddupalli explained the purpose of the Plant Health Innovation Platforms in Africa, Asia and Latin America, leveraging the partners’ research sites. Combining innovations from the CGIAR system, national partners and the private sector, these platforms will enable the co-creation and validation of pest and disease management packages, with the aim of significantly improving adoption of effective and affordable plant health innovations by smallholder farmers.
Removing the barriers for data sharing
The Plant Health Initiative team has recently collected and collated information from national partners and the private sector on actions needed to remove constraints on sharing pest and disease surveillance data. Potential solutions include improved training of national partners, joint research projects, pre-defined processes for data sharing, and focusing on work that meets national and regional priorities.
These approaches will inform the sharing of data collected through the Initiative. For example, researchers are gathering surveillance data on 15 crop pests affecting seven different plants in 25 countries, with the expectation of collecting more than 44,000 samples from 2,100 sites in 2022 alone, with plans for sharing the results with partner institutions.
Boddupalli also emphasized the importance of ramping up remote sensing and drone usage, wherever feasible, for diagnostics and surveillance. However, the current gaps in accessing data and computing facilities in the Global South need to be addressed to make this a reality.
“The OneCGIAR Plant Health Initiative and the Global Burden of Crop Loss project have excellent complementarity,” said Boddupalli. Both have an opportunity to generate and share robust data on crop loss due to existing and emerging crop pests and diseases and use this data to drive effective policy change on plant health management.”

The intersection between agriculture and peace has been brought to the forefront of the news agenda this year due to the Ukraine crisis, which has caused widespread disruption to wheat supply chains – disruptions that are contributing to food insecurity for millions of people worldwide.
Agriculture was therefore a compulsory topic for the International Week of Science and Peace, and formed the main theme for an online fireside chat between Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), and the Hon. Sharon Burke on November 8.
Burke was the director of New America’s Resource Security program and a senior advisor to New America’s Future of War project in the Department of Defense. She served in the administrations of Barack Obama, George W. Bush, and Bill Clinton.
Futureproofing security and food
“[Food] is a foundational element of all security,” explained Burke, when asked about the connection between the two. “We are facing global pressures. Everything that’s made us successful has also made us vulnerable – with biodiversity loss, with climate change. The challenge of having that foundational element of food security has never been harder than it is right now.”
This is a central vision of CIMMYT as a Wallace center, which Burke referenced to highlight how conflict and food insecurity drive one another: “It’s this terrible knot where things are connected. But when we add in climate change, biodiversity loss and pollution and other elements of our modern life, it’s more important than ever to understand how these elements fit together.”
“Peace, prosperity, and equity… are more relevant than ever in the environment we are working in,” agreed Govaerts.
Govaerts then invited Burke to offer recommendations for the development of CIMMYT’s new strategy. She suggested three points to consider:
How is climate change going to shift what agricultural production and productivity means – 10 years from now, 20 years from now, 30 years from now?
In that world, how does that reflect through your research and development priorities?
How do you continue to have that dialogue with farmers, so that you affect them, and they affect you, and what are the ways to make sure that you deepen that and the equity that’s inherent in that conversation?
Govaerts reflected on recent examples from history where conflict destabilized the global food system, such as the Arab Spring as provoked by consecutive droughts that heavily impacted wheat crops. Burke agreed that it was essential to build peace and secure food supplies simultaneously, always having peace as the end goal before any conflict even begins, and the importance of showing the systems effect to donors to encourage future investment.
“One of the reasons that I really love what CIMMYT does, is that you’re talking about not just food security as some abstract concept but as the people and the places where it’s created,” shared Burke.
CIMMYT’s role in peacebuilding
Burke highlighted the commitment from the United States Government to invest money in food security and food assistance, not just for necessary emergency aid but also for improving food production, farming, and last mile technology.
“How can we leverage this investment that is being made now in an emergency to be one that also builds resilience for this longer-term emergency that we are all facing?” she asked, encouraging research and development organizations to always evidence the impact of their work.
In her closing words, Burke expressed high levels of admiration for our scientists. “You get to actually touch the problem and deliver the solution and work in that two-way dialogue with farmers and that you get to bring that all together – how we think about a problem, how we come up with novel science and technology for solving the problem, and then you get to actually carry it to the field and make it work.”
“You’re not just thinking about peace or researching about peace – you’re delivering it!”
The largest real-world test of grains that grow year after year without replanting is showing promise for saving money, helping the environment, and reducing labor in China.
Initial trials with perennial rice as part of the Sustainable Agrifood Systems (SAS) program by the International Maize and Wheat Improvement Center (CIMMYT) suggest the crop could be a game changer for agriculture and food security.
The next phase of the research will determine whether farmers wish to adopt Perennial Rice 23 (PR23), which has been developed by breeding an Asian variety of rice with a wild, perennial relative from Nigeria.
For the first time in Zambia, a special Ministry of Agriculture committee has endorsed innovative sustainable intensification practices to diversify maize-based farming systems and boost the food and nutritional security of millions of small farm households, while enriching depleted soils.
Zambia’s recently formed “National Advisory Committee for the Approval/Validation of Candidate Technologies or Agronomic Practices” approved in September the release to farmers of three new systems for better yields and soil maintenance: growing maize between “hedge-rows” of legume trees; or in rows side-by-side with grain legumes as strip crops; or on permanent, raised soil beds or ridges.
Legume trees and grain legumes enhance soil nitrogen and organic matter content, and legume grains themselves are a valuable, alternative food, rich in protein for rural households. Raised soil beds and ridges can keep soils oxygenated and productive when heavy rainfall floods the fields, as can often occur in northern and northwestern Zambia.
All three systems can be bundled with conservation agriculture approaches, which are based on the principles of minimum soil disturbance, keeping crop residues on the soil, and growing a more diverse selection of crops.
“The official clearing of these transformative cropping technologies is a huge milestone for the project and for Zambia’s resource-poor farmers,” said Christian Thierfelder, CIMMYT principal cropping systems agronomist based in southern Africa who, as part of SIFAZ, is testing and disseminating maize cropping practices that boost harvests, enrich soils, and capture and conserve moisture. “We’re working closely with Zambia’s MoA and the FAO, planning research trials, demonstrations and promotion to reach 20,000 farmers as a first step.”
An essential crop
Maize is the number-one food staple in sub-Saharan Africa, sown by some 300 million smallholder farmers using seasonal rains. A leading crop as well for Zambia’s small-scale, subsistence, and often impoverished farmers, maize grows poorly in extreme heat, infertile soils, and extended dry weather. Failed maize crops can bring hunger to smallholders and their families, for whom risks are high and formal safety nets are non-existent.
The EU recently announced that it will provide an additional EUR 20 million in funding for SIFAZ, now three years old and operating in five provinces and 27 districts of Zambia.
The cropping practices submitted to the National Advisory Committee by Thierfelder and his colleagues conform to a sustainable intensification assessment framework developed by the Feed the Future Innovation Lab for Collaborative Research on Sustainable Intensification of the US Agency for International Development (USAID) and Kansas State University.
“The framework provides a set of indicators for evaluating technologies according to their effects on productivity, economics, the environment, and social and human conditions — domains considered essential for sustainable agriculture systems,” Thierfelder explained. “The framework is well suited for smallholder farm settings, where agriculture is linked to development goals such as alleviating poverty, avoiding land degradation, increasing food and nutrition security, and supporting women’s empowerment.”

Mustafa Alisarli, Bolu Abant Izzet Baysal University rector, is awarded for hosting this symposium by the representative of the Turkish Ministry of Agriculture and Forestry, General Directorate of Agricultural Research and Policies (GDAR), Dr Suat Kaymak.
The International Maize and Wheat Improvement Center (CIMMYT) coordinated the VIII International Cereal Nematode Symposium between September 26-29, in collaboration with the Turkish Ministry of Agriculture and Forestry, the General Directorate of Agricultural Research and Policies and Bolu Abant Izzet Baysal University.
As many as 828 million people struggle with hunger due to food shortages worldwide, while 345 million are facing acute food insecurity – a crisis underpinning discussions at this symposium in Turkey focused on controlling nematodes and soil-borne pathogens causing reduced wheat yields in semi-arid regions.
A major staple, healthy wheat crops are vital for food security because the grain provides about a fifth of calories and proteins in the human diet worldwide.
Seeking resources to feed a rapidly increasing world population is a key part of tackling global hunger, said Mustafa Alisarli, the rector of Turkey’s Bolu Abant Izzet Baysal University in his address to the 150 delegates attending the VIII International Cereal Nematode Symposium in the country’s province of Bolu.
Suat Kaymak, Head of the Plant Protection Department, on behalf of the director general of the General Directorate of Agricultural Research and Policies (GDAR), delivered an opening speech, emphasizing the urgent need to support the CIMMYT Soil-borne Pathogens (SBP) research. He stated that the SBP plays a crucial role in reducing the negative impact of nematodes and pathogens on wheat yield and ultimately improves food security. Therefore, the GDAR is supporting the SBP program by building a central soil-borne pathogens headquarters and a genebank in Ankara.
Discussions during the five-day conference were focused on strategies to improve resilience to the Cereal Cyst Nematodes (Heterodera spp.) and Root Lesion Nematodes (Pratylenchus spp.), which cause root-health degradation, and reduce moisture uptake needed for proper development of wheat.
Richard Smiley, a professor emeritus at Oregon State University, summarized his research on nematode diseases. He has studied nematodes and pathogenic fungi that invade wheat and barley roots in the Pacific Northwest of the United States for 40 years. “The grain yield gap – actual versus potential yield – in semiarid rainfed agriculture cannot be significantly reduced until water and nutrient uptake constraints caused by nematodes and Fusarium crown rot are overcome,” he said.
Experts also assessed patterns of global distribution, exchanging ideas on ways to boost international collaboration on research to curtail economic losses related to nematode and pathogen infestations.
A special session on soil-borne plant pathogenic fungi drew attention to the broad spectrum of diseases causing root rot, stem rot, crown rot and vascular wilts of wheat.
Soil-borne fungal and nematode parasites co-exist in the same ecological niche in cereal-crop field ecosystems, simultaneously attacking root systems and plant crowns thereby reducing the uptake of nutrients, especially under conditions of soil moisture stress.
Limited genetic and chemical control options exist to curtail the damage and spread of these soil-borne problems which is a challenge exacerbated by both synergistic and antagonistic interactions between nematodes and fungi.
Nematodes, by direct alteration of plant cells and consequent biochemical changes, can predispose wheat to invasion by soil borne pathogens. Some root rotting fungi can increase damage due to nematode parasites.
Integrated managementFor a holistic approach to addressing the challenge, the entire biotic community in the soil must be considered, said Hans Braun, former director of the Global Wheat Program at CIMMYT.
Braun presented efficient cereal breeding as a method for better soil-borne pathogen management. His insights highlighted the complexity of root-health problems across the region, throughout Central Asia, West Asia and North Africa (CWANA).
Richard A. Sikora, Professor emeritus and former Chairman of the Institute of Plant Protection at the University of Bonn, stated that the broad spectrum of nematode and pathogen species causing root-health problems in CWANA requires site-specific approaches for effective crop health management. Sikora added that no single technology will solve the complex root-health problems affecting wheat in the semi-arid regions. To solve all nematode and pathogen problems, all components of integrated management will be needed to improve wheat yields in the climate stressed semi-arid regions of CWANA.
Building on this theme, Timothy Paulitz, research plant pathologist at the United States Department of Agriculture Agricultural Research Service (USDA-ARS), presented on the relationship between soil biodiversity and wheat health and attempts to identify the bacterial and fungal drivers of wheat yield loss. Paulitz, who has researched soil-borne pathogens of wheat for more than 20 years stated that, “We need to understand how the complex soil biotic ecosystem impacts pathogens, nutrient uptake and efficiency and tolerance to abiotic stresses.”
Julie Nicol, former soil-borne pathologist at CIMMYT, who now coordinates the Germplasm Exchange (CAIGE) project between CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) at the University of Sydney’s Plant Breeding Institute, pointed out the power of collaboration and interdisciplinary expertise in both breeding and plant pathology. The CAIGE project clearly demonstrates how valuable sources of multiple soil-borne pathogen resistance in high-yielding adapted wheat backgrounds have been identified by the CIMMYT Turkey program, she said. Validated by Australian pathologists, related information is stored in a database and is available for use by Australian and international breeding communities.
Economic losses
Root-rotting fungi and cereal nematodes are particularly problematic in rainfed systems where post-anthesis drought stress is common. Other disruptive diseases in the same family include dryland crown and the foot rot complex, which are caused mainly by the pathogens Fusarium culmorum and F. pseudograminearum.
The root lesion nematode Pratylenchus thornei can cause yield losses in wheat from 38 to 85 percent in Australia and from 12 to 37 percent in Mexico. In southern Australia, grain losses caused by Pratylenchus neglectus ranged from 16 to 23 percent and from 56 to 74 percent in some areas.
The cereal cyst nematodes (Heterodera spp.) with serious economic consequences for wheat include Heterodera avenae, H. filipjevi and H. latipons. Yield losses due to H. avenae range from 15 to 20 percent in Pakistan, 40 to 92 percent in Saudi Arabia, and 23 to 50 percent in Australia.
In Turkey, Heterodera filipjevi has caused up to 50 percent crop losses in the Central Anatolia Plateau and Heterodera avenae has caused up to 24 percent crop losses in the Eastern Mediterranean.
The genus Fusarium which includes more than a hundred species, is a globally recognized plant pathogenic fungal complex that causes significant damage to wheat on a global scale.
In wheat, Fusarium spp. cause crown-, foot-, and root- rot as well as head blight. Yield losses from Fusarium crown-rot have been as high as 35 percent in the Pacific Northwest of America and 25 to 58 percent in Australia, adding up losses annually of $13 million and $400 million respectively, due to reduced grain yield and quality. The true extent of damage in CWANA needs to be determined.
Abdelfattah Dababat, CIMMYT’s Turkey representative and leader of the soil-borne pathogens research team said, “There are examples internationally, where plant pathologists, plant breeders and agronomists have worked collaboratively and successfully developed control strategies to limit the impact of soil borne pathogens on wheat.” He mentioned the example of the development and widespread deployment of cereal cyst nematode resistant cereals in Australia that has led to innovative approaches and long-term control of this devastating pathogen.
Dababat, who coordinated the symposium for CIMMYT, explained that, “Through this symposium, scientists had the opportunity to present their research results and to develop collaborations to facilitate the development of on-farm strategies for control of these intractable soil borne pathogens in their countries.”
Paulitz stated further that soil-borne diseases have world-wide impacts even in higher input wheat systems of the United States. “The germplasm provided by CIMMYT and other international collaborators is critical for breeding programs in the Pacific Northwest, as these diseases cannot be managed by chemical or cultural techniques,” he added.

Road ahead
Delegates gained a greater understanding of the scale of distribution of cereal cyst nematodes and soil borne pathogens in wheat production systems throughout West Asia, North Africa, parts of Central Asia, Northern India, and China.
After more than 20 years of study, researchers have recognized the benefits of planting wheat varieties that are more resistant. This means placing major emphasis on host resistance through validation and integration of resistant sources using traditional and molecular methods by incorporating them into wheat germplasm for global wheat production systems, particularly those dependent on rainfed or supplementary irrigation systems.
Sikora stated that more has to be done to improve Integrated Pest Management (IPM), taking into consideration all tools wherever resistant is not available. Crop rotations for example have shown some promise in helping to mitigate the spread and impact of these diseases.
“In order to develop new disease-resistant products featuring resilience to changing environmental stress factors and higher nutritional values, modern biotechnology interventions have also been explored,” Alisarli said.
Brigitte Slaats and Matthias Gaberthueel, who represent Swiss agrichemicals and seeds group Syngenta, introduced TYMIRIUM® technology, a new solution for nematode and crown rot management in cereals. “Syngenta is committed to developing novel seed-applied solutions to effectively control early soil borne diseases and pests,” Slaats said.
It was widely recognized at the event that providing training for scientists from the Global North and South is critical. Turkey, Austria, China, Morocco, and India have all hosted workshops, which were effective in identifying the global status of the problem of cereal nematodes and forming networks and partnerships to continue working on these challenges.
