Prioritizing the protection of biodiversity is an essential part of mitigating and adapting to the effects of climate change and global warming. At the 15th meeting of the Conference of the Parties to the UN Convention on Biological Diversity (CBD) (COP15), held between December 7-19 in Montreal, Canada, emphasis was placed on the important role of nature in meeting the Sustainable Development Goals (SDGs), proposing the adoption of a bold global biodiversity framework that addresses the key drivers of nature loss to secure health and wellbeing for humanity and for the planet.

On December 7, scientists from the International Maize and Wheat Improvement Center (CIMMYT), together with colleagues from CGIAR research centers and the secretariat of the International Treaty on Plant Genetic Resources for Food and Agriculture, presented at a COP15 side event on how Digital sequence information (DSI) is changing the way genetic resources are used in agricultural research and development and implications for new benefit-sharing norms.

The session, organized by the CGIAR Initiative on Genebanks explored the role of DSI to conserve crop and livestock genetic diversity and explore and utilize that diversity in plant and animal breeding programs.

Carolina Sansaloni, wheat germplasm bank curator and genotyping specialist, illustrated how DSI is being used in the CIMMYT wheat collection to analyze structure, redundancies, and gaps, further detailing how generation and use of DSI to conduct similar analyses within national genebanks in Latin America is being supported through collaborative efforts of CIMMYT and the Alliance of Bioversity and CIAT.

CIMMYT principal scientist Sarah Hearne focused on the application of DSI to interrogate broad swathes of crop genetic diversity for potential climate change adaptation, providing examples of work from the Allele Mining Initiative projects, Mining Useful Alleles and Fast Tracking Climate Solutions, alongside earlier work funded by the Mexican Government.

The take-home message was that genetic diversity and germplasm bank collections, when explored at “global scale” with modern tools and diverse partnerships, offer a powerful resource in the efforts to mitigate the impacts of climate change. This potential is only realized through appropriate generation and sharing of DSI generated from collections of many countries of origin.

Sansaloni and Hearne also contributed to a discussion paper, titled “Digital sequence information is changing the way genetic resources are used in agricultural research and development: implications for new benefit sharing norms”. This article, developed by scientists and germplasm law experts from across the CGIAR, provides a more detailed assessment of CGIAR use of DSI and the benefit sharing options being considered by the Contracting Parties to the Convention on Biological Diversity.

Combining improved seed varieties and index insurance to address drought losses

Written by Sarah McLaughlin on . Posted in In the media.

This VoxDevTalk features Paswel Marenya, Adoption and Impact Assessment Economist at the International Maize and Wheat Improvement Center (CIMMYT), being interviewed about a recent study, “Bundling Genetic and Financial Technologies for More Resilient and Productive Small-scale Agriculture”.

To test solutions that could mitigate the impacts of drought, the study used randomized control trials to test the impact of combining drought-resistant seeds and index insurance in Mozambique and Tanzania.

Results show that combining these two technologies expands their benefits: using the improved seeds reduces insurance costs, and having insurance to begin with counteracts the risk of adopting the seeds. Farmers who use both technologies have greater resilience to drought in the short- and long-term.

Demonstrating the benefits to farmers and informing the scaling-up of the solution-bundling approach was also found to be important.

A renewed CGIAR can better support South Asia to determine its food future

Written by Sarah McLaughlin on . Posted in In the media.

In this article, Temina Lalani-Shariff, Regional Director of South Asia at CGIAR, explores the evolution of CGIAR to meet changing global needs, such as the critical challenge of ending hunger, poverty and inequality across South Asia by 2030 while reaching the climate goals of each country. “A reinvented CGIAR can offer greater flexibility and leadership in three key areas to accelerate the region’s agricultural development and its multiplier benefits for livelihoods, health and climate action,” said Lalani-Shariff.

Highlighting work by the International Maize and Wheat Improvement Center (CIMMYT) to target the spread of crop pests and diseases in Kenya, Lalani-Shariff explains how this success can transfer to fighting fall armyworm (FAW) in South Asia. She cites CGIAR’s experience in scaling innovations and solutions in a variety of agroecologies and environments in partnership with national research institutes, as well as examples from the Seeds Without Borders Initiative and climate-smart villages.

Lalani-Shariff explains the purpose of CGIAR’s Regional Integrated Initiative Transforming Agrifood Systems in South Asia (TAFSSA), which is combining efforts in South Asia to achieve agrifood systems that are more productive and environmentally sound, and support equitable access to sustainable, nutritious diets. Collaboration between CGIAR research centers on Initiatives like this offers opportunities to build effective networks and partnerships for addressing future challenges.

How does physical disturbance of soil impact carbon mineralization?

Written by Sarah McLaughlin on . Posted in Publications.

Higher levels of potential carbon mineralization (Cmin) in soil indicate that the soil is healthier. Many reports indicate that Cmin in agricultural soils increases with reductions in soil disturbance through tillage, but the mechanisms driving these increases are not well understood.

The International Maize and Wheat Improvement Center (CIMMYT) has established a network of research platforms in Mexico, where collaborating scientists evaluate conservation agriculture and other sustainable technologies to generate data on how to improve local production systems. This network of research trials, many of which have over five years in operation, allowed us to participate with Mexican sites in the North American Project to Evaluate Soil Health Measurements (NAPESHM). This project aimed to identify widely applicable soil health indicators and evaluate the effects of sustainable practices on soil health in 124 long-term experiments across Canada, the United States of America, and Mexico.

Experienced field teams from CIMMYT sampled the soils from 16 experiments in Mexico, which were then analyzed by the Soil Health Institute for this study. Potential carbon mineralization, 16S rRNA sequences, and soil characterization data were collected, with results demonstrating that microbial (archaeal and bacterial) sensitivity to physical disturbance is influenced by cropping system, the intensity of the disturbance, and soil pH.

A subset of 28 percent of amplicon sequence variants were enriched in soils managed with minimal disturbance. These enriched sequences, which were important in modeling Cmin, were connected to organisms that produce extracellular polymeric substances and contain metabolic strategies suited for tolerating environmental stressors.

The unique sampling design of this study – analyzing across a variety of agricultural soils and climate – allows to evaluate management impacts on standardized measures of soil microbial activity. Additionally, understanding the microbial drivers of soil health indicators like Cmin can help with the interpretation of those indicators and ultimately the understanding of how to better manage soils.

Inspiring future generations of scientists

Written by Sarah McLaughlin on . Posted in News.

Evidence shows that for every US $1 invested in anticipatory action to safeguard lives and livelihoods, up to US $7 can be saved by avoiding losses in disaster-affected communities, highlighting the power of agricultural research and development that can be continued by the scientists of the future.

This message was reiterated at the Global Food Security Forum for Young Scientists on December 2-3, designed to bring together scientists, scholars, and innovators from different subjects to discuss their research findings and exchange innovative ideas on all aspects of global food security. The event was co-organized by Huazhong Agricultural University (HZAU), China, the International Food Policy Research Institute (IFPRI), the International Maize and Wheat Improvement Center (CIMMYT), and the Leibniz Institute of Agricultural Development in Transition Economies (IAMO).

Topics included the resilience of global food systems and food supply chains, change of dietary patterns and transition of agrifood systems, digital and smart food production, and sustainable agricultural development and maintenance of the environment.

On behalf of CIMMYT Director General Bram Govaerts, agronomist Iván Ortiz-Monasterio presented at the launch event. “Investing in agriculture and a safe and peaceful future is something that CIMMYT and China can build together,” explained Monasterio. “We can develop networks and platforms of collaboration. You have excellent research institutes, and we can combine our capabilities.”

Govaerts then presented a plenary session on the power of young researchers to transform agri-food systems (above), reflecting on the disruption to global supply chains caused by the conflict between Russia and Ukraine, the COVID-19 pandemic, climate change, and high levels of inflation.

“For you as the young, new generation, for you as scientists that need to design the future, it is very important to ask you one central question: when historians pick up their pens and write the story of the 21st century, what will it say about you?” asked Govaerts, as he emphasized training opportunities through the CIMMYT Academy and stories from young scientists at CIMMYT, such as Leonardo Crespo-Herrera, recent winner of the 2022 Japan International Award for Young Agricultural Researchers.

At the conclusion of the conference, Govaerts was also appointed as an advisor of the Global Food Security Forum for Young Scientists.

Using ENM principles to preserve soil health

Written by Sarah McLaughlin on . Posted in Publications.

In a new Frontiers publication, scientists from the International Maize and Wheat Improvement Center (CIMMYT) outline how to achieve an ecologically based approach to sustainable management of soil fertility, particularly for smallholders.

What is ecological nutrient management (ENM)?

Across the globe, smallholder farming communities only have limited resources to improve their financial and food security, and soil degradation is common. Ecological nutrient management (ENM), an agroecological approach to managing the biogeochemical cycles that regulate soil ecosystem services and soil fertility, can prevent degradation and preserve soil health.

Five principles guide ENM strategies:

  • Building soil organic matter and other nutrient reserves.
  • Minimizing the size of nitrogen (N) and phosphorus (P) pools that are most vulnerable to loss.
  • Maximize agroecosystem capacity to use soluble, inorganic N and P.
  • Use functional biodiversity to maximize presence of growing plants, biologically fix nitrogen and access sparingly soluble phosphorus.
  • Construct agroecosystem and field scale mass balances to track net nutrient flows over multiple growing seasons.

Using functionally designed polycultures, diversified rotations, reduced fallow periods, increased reliance on legumes, integrated crop-livestock production, and use of a variety of soil amendments exemplify how ENM works in practice. A key principle is to underpin agroecosystem resilience through the promotion of soil organic matter accrual and restoration of soil function.

Strategic increases of spatial and temporal plant species diversity are used, that meet farmer requirements. This often involves perennial or semi-perennial bushes and vines that provide food, fuel and fodder while restoring soil fertility. ENM long-term management systems can increase yields, yield stability, profitability, and food security, thus addressing a range of smallholder needs.

Fertilizer supply shortages are a chronic problem in Nepal, where thousands of farmers are often unable to access the required quantities on time. This is particularly common during the cultivation of rice — the major staple food crop for the country.

Some of the critical challenges to meeting fertilizer demand include limitations to import mechanisms and budget allocation for fertilizer subsidies by the Government of Nepal. Additionally, the successive COVID-19-induced lockdowns and Russia-Ukraine war have further deepened the crisis in the past two years by significantly delaying imports and increasing fertilizer prices. This continuous gap in supply has compelled farmers to buy fertilizers from the country’s unofficial or “gray” markets.

To address these shortcomings, researchers on the Nepal Seed and Fertilizer (NSAF) project, implemented by the International Maize and Wheat Improvement Center (CIMMYT), have been supporting the Fertilizer Association of Nepal (FAN) and the Ministry of Agriculture and Livestock Development (MOALD) to resolve policy issues that will enhance fertilizer distribution efficiency.

On 23 September 2022, the NSAF project team joined representatives from the International Fertilizer Development Center (IFDC) and FAN to organize a policy dialogue around improving the country’s fertilizer supply system. Held in Kathmandu, the event brought together concerned public and private sector stakeholders to discuss existing challenges and propose different policy alternatives that ensure the timely availability of fertilizers in the required quantities.

Representatives from FAN presented the key issues and challenges in the sector while NSAF project coordinator Dyutiman Choudhary presented the findings of different fertilizer policy studies conducted jointly with local partners. The results showed that involving the private sector in distribution improved farmers’ access to fertilizers compared to distribution carried out solely by cooperatives. The study also indicated a potential to reduce fertilizer subsidies and increase import volume to help meet demand.

Improving national supply systems

The event featured a panel discussion, where participants shared their experiences and outlined the issues faced by private sector importers, logistic service providers and retailers, and policymakers from federal and provincial governments while engaging in their respective functions. The panel members also suggested a number of different ways to improve national fertilizer supply systems, such as:

  1. Restructuring fertilizer subsidy programs, i.e. reducing the current subsidy by 20-30% (a recommendation from the NSAF assessment) and using budget savings to increase imports and allocate subsidies based on fertilizer demand.
  2. Making a procurement process timeline to ensure timely fertilizer supply for three major crops — rice, wheat, and maize — and importing about 30% of the total fertilizer through Government-to-Government (G2G) agreement.
  3. Implementing a crisis management strategy by maintaining buffer stocks (20% of the demand).
  4. Ensuring a level playing field for the private sector in the import and distribution of the fertilizers.

The dialogue concluded with mutual agreement by stakeholders from the public and private sectors to improve local fertilizer distribution through private sector engagement. They agreed to revise some clauses specified in the Nepal Fertilizer Distribution Directive 2020 related to profit margins, volumes, classification of fertilizer distributors and selling fertilizers. Govinda Prasad Sharma, secretary of MOALD, informed attendees that the ministry has already started planning fertilizer procurement based on actual demand and gave assurances about G2G agreements with neighboring countries such as India to bring in fertilizers for distribution during times of peak demand. Sharma also agreed to continue supporting the private sector in capacity building to import fertilizers and to revise subsidies to make more fertilizers available.

“It is our great pleasure to see all fertilizer-related stakeholders in a common platform, which is critical to bring out key issues and cooperation between the public and private sector,” said Lynn Schneider, deputy director of the Economic Growth Office at USAID Nepal. Schneider also emphasized the importance of generating efficiency in estimating fertilizer demand and supply and fertilizer types by using Nepal’s digital soil map, working in close coordination with provincial and local governments, and increasing the role of the private sector to ensure fertilizer supply to meet crop requirements in the peak season.

The Nepal Seed and Fertilizer project is supported by the United States Agency for International Development (USAID) and is a flagship project in Nepal. It aims to build competitive and synergistic seed and fertilizer systems for inclusive and sustainable growth in agricultural productivity, business development and income generation in Nepal.

Participatory action research identifies solutions for improved seed storage in Bangladesh

Written by Sarah McLaughlin on . Posted in Publications.

Traditional and alternative seed storage methods have been compared in a participatory household trial co-designed by the International Maize and Wheat Improvement Center (CIMMYT) and smallholder farmers in Bangladesh, demonstrating how farmers can be involved in agricultural research.

In the summer monsoon season preceding planting in the winter, farmers typically use low-density polyethylene (LDPE) bags contained within woven polypropylene bags to store their wheat seed. Seed quality typically deteriorates over the monsoon as a result of increased seed moisture and pests that are associated with high humidity and temperature.

After initially being consulted by survey and detailed focus group interactions on the design of the trial, 80 wheat farming households participated in a 30-week action research process by conducting trials to compare seed storage methods. This included comparing hermetic SuperGrainbags® (Premium RZ) against LDPE bags, both with and without the addition of dried neem tree leaves (Azadirachta indica), the latter representing a common method used by farmers in Bangladesh to improved stored seed.

Results of the trials demonstrated that seed germination and seedling coleoptile length were greater, and that seed moisture was maintained at levels close to before storage in SuperGrainbags® compared to LDPE bags. The use of neem however had no effect on these factors.

Furthermore, hermetic bags were more effective in lessening seed damage caused during the storage process, but neem slightly reduced damage rates for seeds stored using traditional methods compared to SuperGrainbags®.

In relation to diseases and pests, SuperGrainbags® suppressed Coleopteran pests and blackspot, while storing neem alongside the seeds in LDPE bags had a slight additional pest suppressive effect.

Scoring by both men and women farmers revealed their preference for SuperGrainbags® hermetic storage. The study recommends actions for value chain development to increase farmers’ access to improved hermetic storage options at low cost.

CIMMYT leads innovation sprint to deliver results to farmers rapidly

Written by Sarah McLaughlin on . Posted in Features.

Smallholder farmers, the backbone of food systems around the world, are already facing negative impacts because of climate change. Time to adapt climate mitigation strategies is not a luxury they have. With that in mind, the Agriculture Innovation Mission for Climate (AIM4C) facilitates innovation sprints designed to leverage existing development activities to create a series of innovations in an expedited timeframe.

At the UN COP27 in Egypt, AIM4C announced its newest round of innovation sprints, including one led by the International Center for Maize and Wheat Improvement (CIMMYT) to enable smallholder farmers to achieve efficient and effective nitrogen fertilizer management. From 2022 to 2025, this sprint will steer US $90 million towards empowering small-scale producers in Africa (Kenya, Malawi, Morocco, Tanzania, and Zimbabwe), Asia (China, India, Laos and Pakistan), and Latin America (Guatemala and Mexico).

“When we talk to farmers, they tell us they want validated farming practices tailored to their specific conditions to achieve greater productivity and increase their climate resilience,” said Sieg Snapp, CIMMYT Sustainable Agrifood Systems (SAS) program director who is coordinating the sprint. “This sprint will help deliver those things rapidly by focusing on bolstering organic carbon in soil and lowering nitrous oxide emissions.”

Nitrogen in China

Working with the Chinese Academy of Agricultural Sciences (CAAS), the sprint will facilitate the development of improved versions of green manure crops, which are grown specifically for building and maintaining soil fertility and structures which are incorporated back into the soil, either directly, or after removal and composting. Green manure can significantly reduce the use of nitrogen-based fertilizers, which prime climate culprits.

“There are already green manure systems in place in China,” said Weidong Cao from CAAS, “but our efforts will integrate all the work being done to establish a framework for developing new green manure crops aid in their deployment across China.”

Triple wins in Kenya

The Kenya Climate Smart Climate Project, active since 2017, is increasing agricultural productivity and building resilience to climate change risks in the targeted smallholder farming and pastoral communities. The innovation sprint will help rapidly achieve three wins in technology development and dissemination, cutting-edge innovations, and developing sets of management practices all designed to increase productive, adaption of climate smart tech and methods, and reduce greenhouse gas (GHG) emissions.

Agricultural innovations in Pakistan

The Agricultural Innovation Program (AIP), a multi-disciplinary and multi-sectoral project funded by USAID, led by CIMMYT, and active in Pakistan since 2015, fosters the emergence of a dynamic, responsive, and competitive system of science and innovation that is ‘owned’ by Pakistan and catalyzes equitable growth in agricultural production, productivity, and value.

“From its beginning, AIP has been dedicated to building partnerships with local organizations and, smallholder farmers throughout Pakistan, which is very much in line with the objectives and goal as envisioned by Pakistan Vision 2025 and the Vision for Agriculture 2030, as Pakistan is a priority country for CIMMYT. However, a concerted effort is required from various players representing public and private sectors,” said Thakur Prasad Tiwari, senior scientist at CIMMYT. “Using that existing framework to deliver rapid climate smart innovations, the innovation sprint is well-situated to react to the needs of Pakistani farmers. “

Policies and partnerships for innovations in soil fertility management in Nepal

The Nepal Seed and Fertilizer (NSAF) project, funded by USAID and implemented by CIMMYT, facilitates sustainable increases in Nepal’s national crop productivity, farmer income, and household-level food and nutrition security. NSAF promotes the use of improved seeds and integrated soil fertility management technologies along with effective extension, including the use of digital and information and communications technologies. The project facilitated the National Soil Science Research Centre (NSSRC) to develop new domain specific fertilizer recommendations for rice, maize, and wheat to replace the 40 years old blanket recommendations.

Under NSAFs leadership, the Ministry of Agriculture and Livestock Development (MOALD) launched Asia’s first digital soil map and has coordinated governmental efforts to collect and analyze soil data to update the soil map and provide soil health cards to Nepal’s farmers. The project provides training to over 2000 farmers per year to apply ISFM principles and provides evidence to the MOALD to initiate a balanced soil fertility management program in Nepal and to revise the national fertilizer subsidy policy to promote balanced fertilizers. The project will also build efficient soil fertility management systems that significantly increase crop productivity and the marketing and distribution of climate smart and alternative fertilizer products and application methods.

Public-private partnerships accelerate access to innovations in South Asia

The Cereal Systems Initiative for South Asia (CSISA), established in 2009, has reached more than 8 million farmers by conducting applied research and bridging public and private sector divides in the context of rural ‘innovation hubs’ in Bangladesh, India, and Nepal. CSISA’s work has enabled farmers to adopt resource-conserving and climate-resilient technologies and improve their access to market information and enterprise development.

“Farmers in South Asia have become familiar with the value addition that participating in applied research can bring to innovations in their production systems,” said Timothy Krupnik, CIMMYT systems agronomist and senior scientist. “Moreover, CSISA’s work to address gaps between national and extension policies and practices as they pertain to integrated soil fertility management in the context of intensive cropping systems in South Asia has helped to accelerate farmers’ access to productivity-enhancing innovations.”

CSISA also emphasizes support for women farmers by improving their access and exposure to improved technological innovations, knowledge, and entrepreneurial skills.

Sustainable agriculture in Zambia

The Sustainable Intensification of Smallholder Farming systems in Zambia (SIFAZ) is a research project jointly implemented by the UN Food and Agriculture Organization (FAO), Zambia’s Ministry of Agriculture and CIMMYT designed to facilitate scaling-up of sustainable and climate smart crop production and land management practices within the three agro-ecological zones of Zambia. “The Innovation Sprint can take advantage of existing SIFAZ partnerships, especially with Zambia’s Ministry of Agriculture,” said Christian Thierfelder, CIMMYT scientist. “Already having governmental buy-in will enable quick development and dissemination of new sustainable intensification practices to increase productivity and profitability, enhance human and social benefits while reducing negative impacts on the environment.”

Food systems that work for people and the environment

Written by Sarah McLaughlin on . Posted in News.

Alice Ruhweza, International Maize and Wheat Improvement Center (CIMMYT) Board Member and Africa Regional Director for the World Wide Fund for Nature (WWF), presented on Nature Positive Food Systems for People and Planet on November 22.

Ruhweza has extensive experience working at the intersection of conservation and development in Africa and globally, fostering successful partnerships with a wide range of international institutions. She sits on the Board of The Global Ever-Greening Alliance and on the steering committee of the Future Earth Water-Food-Energy Nexus working group.

Agriculture has a growing environmental footprint, explained Ruhweza, and food emissions are expected to double by 2050. Exponential action is needed to find ways for food systems to co-exist successfully alongside biodiversity, while providing and maintaining healthy diets for humanity.

Ruhweza suggested three solutions for re-thinking the relationship between agriculture and nature: protecting the remaining natural habits from conversion to agriculture; managing agricultural landscapes in a way that support agriculture to enhance the richness and abundance of biodiversity and ecosystem functions, reduces greenhouse gas (GHG) emissions, and enhances resilience to climate change; and restoring degraded agricultural lands and soils to healthy natural habitats or to support sustainable food production.

Organizations like CIMMYT have an opportunity to close the triple gap: producing enough healthy good for a growing population on the same extent of cropland available today, while reducing farm level emissions.

Plant breeding must adapt to climate change, finds study

Written by Sarah McLaughlin on . Posted in Publications.

Breeding is a vital part of the global agrifood system, enabling scientists to adapt crops to developing environmental factors, support improved crop management, and inform policy interventions on global food production. The challenge to crop breeding increases every year, as farmers experience more of the effects of climate change, while the population and food demand continue to rise.

Research by the International Maize and Wheat Improvement Center (CIMMYT) has determined that climate change is affecting the objectives, efficiency, and genetic gains of current plant breeding, causing limitations to the breeding approach of the next generation.

The study found that climate change necessitates a faster breeding cycle and must drive changes in breeding objectives by putting climate resilience as the top priority.

“The risk of multiple crop failure due to climate change is very real. Breeding must become more deterministic in terms of adaption if we are to avert food price-hikes, hunger, and social unrest,” said Matthew Reynolds, Distinguished Scientist and Head of Wheat Physiology at CIMMYT.

Challenges in developing climate-ready crops originate from the paradox between urgent breeding requirements prompted by climate change and the limited understanding of how different genotypes interact with the climates. Integrating multiple disciplines and technologies including genotyping, phenotyping, and envirotyping can contribute to the development and delivery of climate-adapted crops in a shorter timeframe.

This year, 7,255 Highly Cited Researcher (HCR) designations were issued to 6,938 individuals globally. The award is given to scientists with papers that rank in the top 1% by citations. Matthew was awarded for his contribution to scientific literature in plant and animal sciences, while José and Jill were awarded for their contributions to scientific literature across several fields of research (cross fields).

Of the world’s population of scientists and social scientists, Highly Cited Researchers are 1 in 1,000.

The analysis highlights disparities in the locations of top cited scientists. For example, 82.9% of recipients are from just ten countries and regions, out of a possible 70, and 71.4% are from the United States of America, China, the United Kingdom, Germany, or Australia. While the recognition is only given to individual scientists, Matthew, José, and Jill’s success is related to strong scientific collaborations worldwide.

CIMMYT and Join Hope sign a partnership agreement on November 14. (Photo: CIMMYT)

The International Maize and Wheat Improvement Center (CIMMYT) and Join Hope have cemented their partnership at a research cooperation agreement signing ceremony on November 14.

Join Hope produce seed products including maize, wheat, cotton, and soybean, as well as fertilizers, agricultural films and other products. The company will be providing some funding for five years and will receive access to CIMMYT’s international wheat nurseries and some maize inbred lines, in addition to training and other services. The funding will strengthen CIMMYT’s research efforts in China and create opportunities for training in Pakistan.

“CIMMYT and China have developed a win-win partnership that was established back in 1974,” said CIMMYT Director General Bram Govaerts. “Over 48 years, we have collaborated and advanced research for agricultural development in the areas of breeding, genomic research, and sustainable farming systems.”

Through this partnership, as much as 10.7 million tons of grain has been added to China’s wheat output. More than 26,000 CIMMYT wheat accessions were introduced and stored in China, and more than 300 wheat cultivars derived from CIMMYT germplasm have been released in China and are currently grown on nearly 10 percent of the Chinese wheat production area.

“The cooperation agreement that we sign today is another step in the right direction,” continued Govaerts. “It will bring us closer to the Chinese farmer and grain consumers who we all aim to serve.”

Scientists and researchers from the International Maize and Wheat Improvement Center (CIMMYT) represented the organization at a wide range of events, covering gender, genebanks, soil health, and digital innovations.

Gender and food security

In an ICC panel discussion on Addressing Food Security through a Gender-Sensitive Lens on November 7, Director General Bram Govaerts presented on CIMMYT’s systems approach to address gender gaps in agriculture. This event formed part of the ICC Make Climate Action Everyone’s Business Forum, which aimed to bring together experts to determine solutions to the planet’s biggest environmental challenges.

Govaerts highlighted the importance of extension and training services targeting female farmers, particularly those delivered by women communicators. This can be achieved through training female leaders in communities, which encourages other women to adopt agricultural innovations. He also emphasized the obstacles to global food security caused by conflict, climate change, COVID-19, and the cost-of-living crisis, which will in turn create more challenges for women in agriculture.

The role of CGIAR genebanks in a climate crisis

Govaerts and Sarah Hearne, principal scientist, introduced the Agriculture Innovation Mission for Climate (AIM4C) innovation sprint on Fast Tracking Climate Solution from Genebank Collections, at a virtual side event organized by the Foundation for Food & Agriculture Research (FFAR).

Hearne explained that the development of current and future varieties is dependent upon breeders sourcing and repackaging native genetic variation in high value combinations. The CGIAR network of germplasm banks holds vast collections of crops that are important for global food and feed supplies. Among the diversity in these collections is currently unexplored and unused native variation for climate adaptation.

Through strong partnerships, multi-disciplinary activities, and the harnessing of diverse skillsets in different areas of applied research and development work, the sprint will help to identify genetic variations of potential value for climate change adaptation and move that variation into products that breeders globally can adopt in their variety development work. Through these efforts, the sprint improves access to specific genetic variation currently sat in the vaults of germplasm banks and facilitates crop improvement programs to develop the varieties that farmers demand.

The sprint is a clear example of the shift in paradigms we are looking for, so that people in the year 2100 know we took the right decisions in 2022 for them to live in a better world, said Govaerts. He continued by emphasizing the need for the initiative to be integrated within the systems it aims to transform, and the importance of accelerating farmers’ access to seeds.

The initiative is only possible because of the existence of the genebank collections that have been conserved for humanity, and due to cross-collaboration across disciplines and sharing of data and resources.

Addressing soil fertility management

Tek Sapkota, senior scientist, presented at Taking Agricultural Innovation to the Next Level to Tackle the Climate Crisis, the AIM4C partner reception on November 11, which gathered critical actors committed to making agriculture one of the most impactful climate solutions. Hosted on the one-year anniversary of the AIM4C launch at COP26 and on the eve of the COP27 day on adaptation and agriculture, the event was a celebration of progress made to date to address the climate crisis by 2025.

Along with 20 partners, CIMMYT submitted an AIM4C innovation sprint on climate-resilient soil fertility management by smallholders in Africa, Asia, and Latin America, which was announced at COP27 alongside other sprints.

Sapkota, who leads a project that is part of CIMMYT’s AIM4C innovation sprint submission, presented alongside the Minister of Climate Change and Environment from the United Arab Emirates, the Secretary of Agriculture for the United States, and the Regional Director for Central Asia, West Asia and North Africa at CGIAR.

Digital solutions for sustainable systems

Tharayil Shereef Amjath Babu, agricultural economist in modeling and targeting, hosted an event on Accelerating Digital Climate Services for resilient food systems in the Global South, exploring the work of two CGIAR Initiatives: Securing the Food Systems of Asian Mega-Deltas (AMD) for Climate and Livelihood Resilience and Transforming Agrifood Systems in South Asia (TAFSSA) on November 17.

In the Global South, farmers are being affected by unreliable weather patterns caused by climate change, which means they can no longer rely on their traditional knowledge. However, demand climate services can fill this vacuum, enabling meteorological agencies to produce accurate climate information, co-create digital climate services for agricultural systems, and support sustainable and inclusive business models.
