The world needs better management of water, soil, nutrients, and biodiversity in crop, livestock, and fisheries systems, coupled with higher-order landscape considerations as well as circular economy and agroecological approaches.
CIMMYT and CGIAR use modern digital tools to bring together state-of-the-art Earth system observation and big data analysis to inform co-design of global solutions and national policies.
Our maize and wheat genebanks preserve the legacy of biodiversity, while breeders and researchers look at ways to reduce the environmental footprint of agriculture.
Ultimately, our work helps stay within planetary boundaries and limit water use, nutrient use, pollution, undesirable land use change, and biodiversity loss.
Sustainable Agrifood Systems Approach for Sudan (SASAS) takes a modular and multi-crop approach, implementing an integrated agrifood system that supports food security, employment, and equity. The project focuses on soil fertility management integrated with agrifood systems based on smallholder farmer productivity gains, leveraging both One CGIAR and non-CGIAR innovation partners to support scaling on the ground by last-mile partners.
SASAS moves beyond humanitarian response and resilience to inclusive agriculture-led economic growth and enables landless and under resourced people to participate in functional and gender-sensitive high-production value chains.
This work contributes to six of the United Nations Sustainable Development Goals (SDGs): Zero Hunger; Good Health and Well-Being for People; Gender Equality; Decent Work and Economic Growth; Responsible Consumption and Production; and Climate Action.

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.

AGG is a collaborative project led by the International Maize and Wheat Improvement Center (CIMMYT) bringing together global partners to advance the development of higher-yielding varieties.
This field day was organized by the Crops Research Institute at Ghana’s Council for Scientific and Industrial Research (CSIR-SARI), the International Institute of Tropical Agriculture (IITA) and the department of agriculture.
During the event, researchers aimed to encourage farmer adoption by familiarizing them with the stress-tolerant hybrids and emphasizing the high and stable grain yields.
To mitigate their amount of greenhouse gas (GHG) emissions, companies and individuals have access to international voluntary carbon offset markets, which are trading systems that financially compensate credit producer participants for offsetting the amount of carbon emitted. An innovative new initiative from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research Institute (ICAR) is working to establish carbon markets among smallholder farmers in India, with the goal of reducing GHG emissions, encouraging climate smart farming practices through financial incentives.
In India, agriculture is one of the biggest sources of GHG emissions – between 14 and 21 percent of all GHGs are attributable to agricultural activities, which derive from the use of farm machinery, rice cultivation, fertilizer use, and other activities. Emissions from agriculture are increasing drastically due to synthetic fertilizers and enteric fermentation from livestock.
Within CIMMYT’s farmer-centered approach, participants in voluntary carbon markets will improve their own financial viability in two ways – through adopting sustainable practices and through receipt of payments from carbon markets. The approach will also employ regenerative interventions such as direct dry seeding of rice, minimal tillage, crop diversification, use of biofertilizers, and perennial cropping all while contributing to an overall reduction in GHG emissions.
“Working with ICAR to engage smallholder farmers with high-quality carbon offsets allows the farmers to offset their unavoidable emissions,” said Vijesh Krishna, senior CIMMYT scientist. “This program promotes inclusiveness because this newly created income is distributed among participating farmers, thereby improving their income.”
These regenerative agriculture interventions will increase and retain soil’s carbon content, water permeability and retention, resulting in crops’ ability to withstand drought, flooding, and temperature stresses. Only a small percentage of farmers currently implement these methods in India.
CIMMYT and ICAR researchers estimate that widespread adoption of these practices, combined with upgraded technologies, has the potential to return the carbon levels in agricultural soils from an average of 0.5 percent back to 1.5 percent. At present, the agricultural soils of India are poor with respect to soil organic carbon.
Carbon markets for smallholders
About 2,000 small holder farmers of Punjab, Haryana, and parts of Maharashtra, all in India, are enrolled in the project through individual partnership agreements. Once farmers implement regenerative agricultural methods, they will be eligible to receive payments for carbon credits generated for 10 to 20 years, conditional upon continuing to use climate-smart practices.
“We believe these efforts can be expanded to other regions of India, and other countries,” said Sieg Snapp, CIMMYT’s Sustainable Agrifood Systems (SAS) program director. “Helping farmers and reducing GHG emissions at the same time is the way forward in dealing the crisis of climate change.”
Farms are geo-tagged and monitored using remote sensing for regenerative farming practices, and soil carbon content will be measured at the beginning and end of the crop cycle. Those that produce rice and wheat with a lower carbon footprint will be identified, so their produce gets purchase and price preferences from those who want to promote lower carbon agriculture.
Digital agronomy tools and satellite imagery analysis to measure and verify soil carbon offsets and on-farm GHG emission levels are essential for scaling small farmer-centered carbon projects. The veracity, transparency, and traceability of each carbon offset have direct implications for its credibility and actual market value. CIMMYT will contribute towards a Measurement, Reporting, and Verification (MRV) platform to expand climate action country-wide.
So far, CIMMYT and ICAR researchers estimate that the enrolled smallholder famers have sequestered between four and five tons of carbon dioxide. After independent third-party auditors verify the data, farmers will be paid based on the amount of GHG reduction, with the first carbon offset payments expected to be issued in 2023.

The International Maize and Wheat Improvement Center (CIMMYT) Director General, Bram Govaerts, participated in a panel discussion on applied maize science to sustainably feed the world as part of the International Maize Congress on October 19-20, 2022 in Argentina.
The congress was organized by the governments of Córdoba and of the Central Region provinces of Argentina, together with the Argentine Maize and Sorghum Association (MAIZAR) and the Córdoba Grain Exchange.
Other panelists for the session included representatives from Argentina’s National Agricultural Technology Institute (INTA), the National Scientific and Technical Research Council (CONICET), and the National University of Mar del Plata.
In his presentation, Govaerts highlighted CIMMYT’s scientific efforts to improve the resilience of grain-based systems and produce sufficient, nutritious, and sustainable diets. He also shared CIMMYT’s determination to adopt a collaborative and future-proof approach to research, factoring in climate change to support effective decision-making processes for food producers and to meet demand for innovations and technologies.

The International Maize and Wheat Improvement Center is working with its partners to support farmers in Zimbabwe embrace conservation agriculture and improved seed varieties to achieve more successful harvests in areas affected by climate change.
The R4 Rural Resilience and ZAMBUKO initiatives aim to help farmers through a number of activities. These include demonstrations of seed and conservation agriculture, field days and seed fairs, which look to develop farmers’ awareness about improved seed and novel varieties.
The fairs highlighted the importance of good seed practices and the benefits of improved varieties to both farmers and seed companies, who attended the events.
The initiative, which is run in collaboration with the Department of Specialist Services (DRSS), the Agricultural Advisory and Rural Development Services (ARDAS) and the World Food Program (WFP), with financial support from the Swiss Agency for Development and Cooperation (SDC) and the United States Agency for International Development (USAID), helps those in the industry see the advantages of improved varieties over old ones, which may have been on the market for more than 20 years.
“It is now very critical for farmers from all walks of life to abandon old varieties which they have grown for decades and adopt the recently released varieties that offer some solutions to the new challenges,” said James Gethi, a seed systems scientist with CIMMYT. “There has been massive investment in research that has specifically focused on addressing the adversity of climate change and variability it brings, such as prolonged dry spells, heat stress, and new diseases that have emerged. As such, it is beneficial to the farmer to shift to the latest varieties as they suit the environmental context better compared to the older varieties.”
In recent years, Zimbabwe has experienced erratic rainfall and severe heatwaves during summer months, which is a key period for the growth of crops. This has led to low yields in various parts of the country, but the situation could improve through the combination of improved agronomy and varieties presented by seed and seed distribution companies who attended the fairs.
“Together with CIMMYT and other partners, we have invested in developing varieties that will help us achieve our annual food security goals,” added Busiso Mavankeni, head of the Crop Breeding Institute (CBI), which is housed within DRSS. “As such, farmers not adopting these new varieties contribute towards a huge waste of beneficial and relevant scientific research. Whilst it is not the farmers’ fault why they haven’t adopted them, we need to take deliberate steps to ensure farmers are aware of these varieties. That is the only way we can stimulate their adoption.”

Improving seed management
One of the project’s core aims is to promote positive seed management practices to both farmer and seed companies. In fact, these seed companies have a key role to play in supporting farmers with this knowledge. Understanding how to store crops in optimal conditions, for example, can lead to a more successful harvest.
“It is essential for both the farmers and local agro dealers to know how to manage seed before sale and planting,” Gethi added. “For example, rarely do farmers check the expiry date of seed when they buy them from an agro dealer. Secondly, when the seed needs to be stored, it is essential for it not to be stored close to heat sources or to be unnecessarily exposed to the sun for prolonged periods. This compromises its germination potential. Furthermore, it is crucial for farmers to only buy seed from registered and reputable agro dealers.”
These important messages were relayed to farmer throughout the project’s demos and field days, which led up to the seed fairs.
In addition to purchasing seeds, farmers had the opportunity to learn about new developments and build relationships in the private sector by attending the fairs.
“With these seed fairs, we have not only brought this multitude of seed and machinery companies to your doorstep so that you easily access good seeds, but so that you can also talk and understand what new products are on offer,” explained Christian Thierfelder, principal cropping systems agronomist, innovation science leader for Africa within CIMMYT. “For this coming season, we do not want to see you growing ancient varieties but would want to see you purchase new products which perform better than the old ones.”
ARDAS agricultural extension officer Canaan Jakata was also encouraged by the success of the project’s activities and is looking forward to seeing the farmers who attended the seed fairs enjoy a successful yield during the upcoming summer season. “I am very keen on assessing the performance of farmers in my ward who bought these improved varieties at the seed fairs as compared to neighboring wards in the district which did not. Regardless of how the season turns out, I expect superior performance from my farmers,” said Jakata.

The fall armyworm is a destructive polyphagous pest that feeds on more than 300 crop species, with a particular appetite for maize. The pest was first reported in Asia in 2018 and has been spreading in the region since then, especially in maize-producing countries of South Asia.
Several campaigns on identifying and managing fall armyworm have been conducted in South Asia, yet the challenge to control the pest remains. The damage caused by fall armyworm to farmers’ fields was reported widely during the 2022 spring maize season in Pakistan and Nepal’s Terai region. Many maize farmers complained about the current economic downturn, price hike of agricultural commodities and the unavailability of safe pesticides to reduce crop losses.
On 21 July 2022, the International Maize and Wheat Improvement Center (CIMMYT) initiated a refresher webinar to share the latest scientific advances and best practices for identifying and managing fall armyworm in South Asia. The platform extended an opportunity for the participants to understand and learn about effective integrated pest management (IPM) approaches being practiced in the region. It also addressed the importance of enabling policies that are crucial to foster innovations to reduce crop yield loss and save the environment from hazardous effects of toxic pesticides.
The Nepal Seed and Fertilizer Project (NSAF) team, supported by the United States Agency for International Development (USAID) and implemented by CIMMYT, organized the virtual event in collaboration with Nepal’s Plant Quarantine and Pesticide Management Center, the Nepal Agricultural Research Council, Nepal’s National Maize Research Program, the Maize and Millet Research Institute in Pakistan, the University of Agriculture Faisalabad and CGIAR’s Plant Health Initiative.
Govinda Prasad Sharma, Secretary of Nepal’s Ministry of Agriculture and Livestock Development and Jason Seuc, director of the Economic Growth Office at USAID Nepal, delivered their opening remarks during the inaugural session. The Secretary emphasized the use of safer methods, including but not limited to mass rearing and releasing of natural enemies of fall armyworm and the deployment of fall armyworm tolerant maize varieties.
“USAID will continue working with partners to advocate and promote IPM practices till the pest becomes of non-economic importance,” said Seuc.
BM Prasanna, director of CIMMYT’s Global Maize Program and OneCGIAR Plant Health Initiative lead emphasized the importance of IPM practices to manage the pest. Prasanna discussed the global efforts to control the pest and shared the progress of fall armyworm tolerant maize seeds which are being released and deployed by CIMMYT partners to help resource poor farmers, especially in Africa.
AbduRahman Beshir, NSAF’s seed systems lead, emphasized the importance of the event and acknowledged the participation of approximately 525 attendees from public and private research institutions, academicians, civil society, private sector, policy decision-makers, CGIAR centers and USAID Nepal. The webinar gathered attendees from 15 countries, including Nepal, India, Bangladesh, Pakistan, Thailand, Myanmar, Sri Lanka and China.
Experts from South Asia presented on a range of topics including the status of fall armyworm and its management in Nepal, Pakistan, Bangladesh and the Pacific Region, IPM practices and experience of using safe pesticides, breeding for native genetic resistance to fall armyworm, and biological control and push-pull strategies. The experts emphasized on the need for collective efforts to strengthen national and international coordination, favorable policies, deployment of fall armyworm tolerant maize varieties, and best response interventions to help farmers battle the fall armyworm and limit its spread.
Efforts to mitigate the impact of fall armyworm attacks are still ongoing. CIMMYT is continuously working to alert farmers and stakeholders on the IPM practices of fall armyworm in the region.

The Ambassador of Mexico to Norway, Ulises Canchola Gutiérrez, delivered a deposit from the International Maize and Wheat Improvement Center (CIMMYT) to the Svalbard Global Seed Vault on October 12.
CIMMYT was the ninth depositor in the Seed Vault in 2022, with a contribution of 263 accessions of maize and 3,548 accession of wheat.
“Professionally, I am pleased to carry out this activity that contributes to the conservation of genetic resources and guarantees food security of two of the major crops that feed the world,” said Rocio Quiroz, assistant research associate at CIMMYT. “When we prepare a shipment as a team, it is extraordinary because we contribute to the perpetuity of each accession deposited in the vault. Very few people have the privilege of doing so.”

What is the Seed Vault?
The Seed Vault is a genebank collection that holds duplicates of seeds from more than 1,700 genebanks around the world, playing the role of a backup collection. By protecting these varieties from catastrophic loss, the Seed Vault contributes towards food security for future generations.
Owned by Norway and managed in partnership between the Norwegian Ministry of Agriculture and Food, NordGen, and the Crop Trust, the Seed Vault currently holds 1,165,041 seed varieties, with capacity for millions more.
In 2020, CIMMYT was the largest contributor, providing 173,779 maize and wheat accessions from 131 countries.

How is germplasm stored at CIMMYT?
CIMMYT’s own germplasm bank contains approximately 150,000 unique collections of wheat seed and its ancestors and is the largest unified collection in the world for a single crop.
For maize, the germplasm bank contains more than 28,000 samples, including the world’s largest collection of maize landraces, representing nearly 90% of maize diversity in the Americas.
Carolina Sansaloni, manager of the wheat genebank at CIMMYT, said, “I am proud of all CIMMYT germplasm bank staff that made a great effort to send an additional 3,800 accessions to the Svalbard as safety duplications. This contribution is for the food security of humanity.”
Effective plant health management is critical for improving the productivity, profitability, sustainability and resilience of agrifood systems. Yet, farming communities, especially in low- and middle-income countries, struggle to contain existing and emerging plant pests and diseases. Each year, these threats cause on average 10–40% losses to major food crops, costing the global economy around US$220 billion. The highest losses are associated with food-deficit regions with fast-growing populations.
Increasing international trade and travel, coupled with weak phytosanitary systems, are accelerating the global spread of pests and diseases. The situation is exacerbated by climate change, with agricultural intensification and diversification driving the emergence of new threats. These burdens fall disproportionately on poorly resourced communities, especially women and youth in rural areas.
Diagnostic capacity, global-scale surveillance data, risk prediction/forecasting and rapid response and management systems for major pests and diseases are still lacking. Inadequate information and knowledge of and access to climate-smart control options leave smallholders and marginalized communities ill-equipped to respond to biotic threats. Environmental and health effects of toxic pesticides, exposure to mycotoxins and acute unintentional pesticide poisoning are major concerns.
Objective
This Initiative aims to protect agriculture-based economies of low- and middle-income countries in Africa, Asia and Latin America from devastating crop pest incursions and disease outbreaksby developing, validating and deploying inclusive innovations, and by leveraging and building viable networks across an array of national, regional and global institutions.
Activities
This objective will be achieved by:
Bridging knowledge gaps and networks for plant health threat identification and characterization, focusing on strengthening the diagnostic and surveillance capacity of national plant protection organizations and national agricultural research and extension systems, and facilitating knowledge exchange on pests and diseases.
Building capability of relevant national stakeholders for risk assessment, and data management and guiding preparedness for rapid response, focusing on controlling the introduction and spread of pests and diseases by developing and enhancing tools, standards and policies.
Improving integrated pest and disease management, focusing on designing and deploying approaches against prioritized plant health threats in targeted crops and cropping systems.
Designing and deploying tools and processes for protecting food chains from contamination, specifically,through innovations for reducing mycotoxin contamination to protect health, increase food/feed safety, enhance trade, diversify end-use and boost income.
Promoting gender-equitable and socially inclusive scaling of plant health innovations to achieve impacts through multistakeholder partnerships, inter-disciplinary research, effective communications and capacity development.

Farmers, development practitioners and scientists gathered at Tropentag 2022 between September 14-16 to answer a question that will affect all our futures: can agroecological farming feed the world?
This year’s event explored the potential of agroecology to contribute to improved nutrition, enhanced natural resource management and farm incomes.
Sieg Snapp, Director of the Sustainable Agrifood Systems (SAS) program at the International Maize and Wheat Improvement Center (CIMMYT) presented on agroecology approaches to enhance learning in a changing world based on experiences with maize-based cropping systems in southern Africa. Snapp suggested that accelerated learning and adaptative capacity are key to the local generation of suitable solutions to agricultural problems, and proposed agroecology as a foundational approach that emphasizes understanding principles, harnessing biological processes, and enhancing local capacity.
Snapp shared how an agroecology living laboratory in Malawi has supported farmer agency around soil health, crop diversification and sustainable intensification since 2013, while living labs are being established in “food territories” in Zimbabwe to support innovation and strategies for evaluating the benefits of farm-scale agroecology approaches. She also explored solutions for pest management, inclusive financing modalities and collaborative innovation generation between farmers and researchers.
Gender and disease-resistant varieties
Michael Euler, Agricultural Resource Economist at CIMMYT, presented in the conference session on technology adoption and dissemination for smallholder farms, which included contributions on the adoption and impact of improved forage production, use of biogas facilities, agroecological management practices, improved wheat seeds, and access to and use genetic diversity in gene banks.
By using questionnaires that were addressed separately to male and female spouses in the household, researchers obtained insights on perceived individual roles in decision-making and agreements. The study found that an increase in the role of the female spouse in household farming decisions is positively associated with the uptake of rust-resistant varieties.
Additional sessions from the event focused on crops and cropping systems, animal production systems, food security and nutrition, agroecology, and food processing and quality.
Today, the International Maize and Wheat Improvement Center (CIMMYT) is excited to share with you the Annual Report 2021: From Discovery to Scaling Up.
Our latest Annual Report captures the three ways in which CIMMYT science makes a difference:
The scientific pathway from discovery and validation: In 2021, we embarked on an ambitious initiative to apply environmental genome-wide association methods to predict how today’s maize, rice, sorghum, cassava, groundnut, and bean varieties will perform in the future under climate scenarios, and help them succeed in three or four decades from now.
Translating science to innovation: Last year, we made important strides in boosting the resilience of maize and wheat to a hotter and drier world — and to the threats of ever-evolving and invasive pests and diseases.
Scaling up innovation for farmers and society: In collaboration with dozens of public- and private-sector partners in the countries where we work, in 2021 we scaled up sustainable technologies and farming practices for hundreds of thousands of farmers.
CIMMYT director general Bram Govaerts presented the current challenges: “A global food crisis fueled by conflict, trade disruptions, soaring commodity prices and climate change.” He also expressed CIMMYT is ready to respond to the immediate and long-term threats facing humanity. “We have solid, science-informed solutions, policy recommendations and proven methodologies that will help avert the global food security crisis that looms,” he said.
We want to thank all our funders and partners for their collaboration and support, year after year.
Climate change is predicted to cause losses of more than 20% in agricultural production by 2050. With a growing global population, crops adapted to the effects of climate change, such as drought and heat, are necessary for the maintenance of productivity levels to meet the demand for food.
Scientists from the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with scientists from the Universidad Autónoma Agraria Antonio Narro, set out to analyze bread wheat landrace traits against seven climactic variables: mean temperature, maximum temperature, precipitation, precipitation seasonality, heat index of mean temperature, heat index of maximum temperature, and drought index. The method used genome-environment associations (GEA) and environmental genome-wide association scans (EnvGWAS), which have traditionally been poorly applied in this type of research.
Based on a sample of 990 bread wheat landraces from the CIMMYT genebank, the study discovered proteins associated with tolerance to drought and heat. With these results, new genotypes with resistant alleles can be selected for breeding programs to produce resistant varieties adapted to extreme environments and the effects of climate change.
This work was implemented by CIMMYT as part of the Seeds of Discovery (SeeD) Initiative in collaboration with Universidad Autónoma Agraria Antonio Narro (UAAAN), made possible by the generous support of the MasAgro project funded by the Government of Mexico’s Secretariat of Agriculture and Rural Development (SADER).

CGIAR research centers involved in the One CGIAR Plant Health Initiative joined forces at the International Plant Health Conference in London on September 21-23, 2022 to highlight the importance of global partnerships in effectively preventing and managing devastating pest and disease outbreaks in the Global South.
In an interactive side event on Plant Health Management in the Global South through Partnerships on September 21, the Plant Health Initiative team presented on and discussed: global diagnostic and surveillance systems against plant pests and diseases; risk assessment and preparedness for proactive response; integrated pest and disease management; mycotoxin mitigation strategy; and gender and social inclusion.
The CGIAR Plant Health Initiative, launched in January 2022, aims to protect agriculture-based economies of low and middle-income countries in Africa, Asia and Latin America from pest and disease outbreaks in major crops by leveraging and building viable networks across an array of national, regional, and international institutions.
Building on a track record of more than 50 years of impactful research, the Plant Health Initiative aims to develop and deploy solutions through partnerships, and to achieve impacts that contribute towards several Sustainable Development Goals (SDGs).
Healthy crops for a healthy planet
Showing the strength of partnerships in action, researchers from the International Maize and Wheat Improvement Center (CIMMYT), Alliance Bioversity-CIAT (ABC), the International Institute of Tropical Agriculture (IITA), the International Potato Center (CIP), and the International Food Policy Research Institute (IFPRI) highlighted the Initiative’s activities and sought feedback from the plant health experts participating in the session.
Martin Kropff, CGIAR Science Director of Resilient Agrifood Systems, welcomed the participants to the session. Prasanna Boddupalli, CGIAR Plant Health Initiative Lead & Director of CIMMYT’s Global Maize Program, introduced the Initiative and its scope, emphasizing the inclusive partnerships. This was followed by presentations from Monica Carvajal (ABC), Lava Kumar (IITA), Alejandro Ortega-Beltran (IITA), Nozomi Kawarazuka (CIP), and Yanyan Liu (IFPRI).
Time was dedicated to engaging participants through Mentimeter polling on specific questions related to plant health management. Participants also shared their views on plant health research coordination, capacity strengthening, and knowledge exchange between the Global North and Global South, with a focus on improving food security and livelihoods of smallholders.
The event was successful not only in generating greater understanding of the Initiative amongst the participants, but also in developing significant interest from the participants to contribute to the Initiative’s goals with collective actions, all for the benefit of smallholders in the low- and middle-income countries of Africa, Asia, and Latin America.
Establishing wider networks for plant health
The Plant Health Initiative team, together with Kropff, also had a productive discussion on September 22 with Osama El-Lissy, International Plant Protection Convention (IPPC) Secretary, on opportunities for joint actions on plant health management in the Global South by IPPC and the CGIAR Plant Health Initiative, together with national partners.
Boddupalli also participated in a workshop on September 20 organized by Euphresco, a network of organizations that fund research projects and coordinate national research in the phytosanitary area, at the Department of Environment, Food & Rural Affairs (DEFRA) in the United Kingdom, on shaping global plant health research coordination. The workshop participants discussed and endorsed several actions for advancing global plant health research coordination.
