How does CIMMYT’s improved maize get to the farmer?
CIMMYT is happy to announce a new, improved tropical maize hybrid that is now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across rainfed tropics of South Asia and similar agro-ecologies. NARS and seed companies are hereby invited to apply for licenses to pursue national release and /or scale-up seed production and deliver these maize hybrids to farming communities.
The deadline to submit applications to be considered during the first round of allocations is 26 Aug 2022. Applications received after that deadline will be considered during subsequent rounds of product allocations.
The newly available CIMMYT maize hybrid, CIM19SADT-01, was identified through rigorous trialing and a stage-gate advancement process which started in 2019 and culminated in the 2020 and 2021 South Asia Regional On-Farm Trials for our South Asian Drought Tolerance (SADT) and Drought + Waterlogging Tolerance (SAWLDT) maize breeding pipelines. The product was found to meet the stringent performance criteria for CIMMYT’s SADT pipeline. While there is variation between different products coming from the same pipeline, the SADT pipeline is designed around the product concept described below:

“For several years, we’ve been building dense data sets with colleagues from the Indian Agricultural Research Council, which have allowed us to unravel complex farm realities through big data analytics, and to determine what agricultural management practices really matter in smallholder systems,” said Andrew McDonald ’94, M.S. ’98, Ph.D. ’03, associate professor of soil and crop sciences in the College of Agriculture and Life Sciences. “This process has confirmed that planting dates are the foundation for climate resilience and productivity outcomes in the dominant rice-wheat cropping systems in the eastern sector in India.”
The research was conducted through the Cereal Systems Initiative for South Asia (CSISA). CSISA, which is led by CIMMYT with the International Rice Research Institute and the International Food Policy Research Institute as research partners, was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems.
Researchers found that farmers in eastern India could increase yield by planting wheat earlier – avoiding heat stress as the crop matures – and quantified the potential gains in yields and farm revenues for the region. They also found that the intervention would not negatively impact rice productivity, a key consideration for farmers. Rice alternates with wheat on the cropping calendar, with many farmers growing rice in the wet season and wheat in the dry season.
The study also provides new recommendations for rice sowing dates and types of cultivars, to accommodate the earlier sowing of wheat.
“Farmers are not just managing single crops. They are managing a sequence of decisions,” said McDonald, who has a joint appointment in the Department of Global Development. “Taking a cropping systems approach and understanding how things cascade and interlink informs our research approach and is reflected in the recommendations that emerged from this analysis. Climate resilient wheat starts with rice.”
The research is the result of years of collaboration with international groups and government agencies in India, which have identified the Eastern Ganges Plain as the area with the most potential growth in production. The region will become essential, McDonald said, as the demand for wheat grows, and climate change makes production more difficult and unpredictable; just this year, record heat waves in March and April and food shortages caused by the war in Ukraine – both of which prompted India’s government to instate a ban on wheat exports – have highlighted the need for increased yields and more sustainable farming practices.
“In the bigger sense, this research is timely because the hazards of climate change aren’t just a hypothetical,” McDonald said. “Many of these areas are stress-prone environments, and extreme weather already constrains productivity. Identifying pragmatic strategies that help farmers navigate current extremes will establish a sound foundation for adapting to progressive climate change.”
Poverty is endemic in the Eastern Ganges Plain, and the region is dominated by small landholders, with varying practices and access to resources. The breadth and specificity of the data collected and analyzed in the study – including field and household survey data, satellite data, and dynamic crop simulations – allowed researchers to understand regional small farms’ challenges and the barriers to change.
“At the end of the day, none of this matters unless farmers opt in,” McDonald said. “There’s a spatial dimension and a household dimension to opportunity. If we can target approaches accordingly, then we hope to position farmers to make management changes that will benefit the entire food system.”
The study was co-authored with researchers from the Australian Department of Primary Industries and Regional Development, the International Rice Research Institute, the International Maize and Wheat Improvement Center, the International Food Policy Research Institute, the Indian Council of Agricultural Research and Bihar Agricultural University. The research was supported by the Bill and Melinda Gates Foundation and the U.S. Agency for International Development through grants to the Cereal Systems Initiative for South Asia, which is led by the International Maize and Wheat Improvement Center.
Institutionalizing Monitoring of Crop Variety Adoption using Genotyping (IMAGE) is a five-year program with the aim of establishing, institutionalizing, and scaling routine monitoring of improved variety adoption and turnover using genotyping.
It is led by country teams in Ethiopia, Nigeria and Tanzania, supported by Context Global Development and the Bill & Melinda Gates Foundation.
Reliable monitoring: IMAGE will assess the varieties that farmers are growing of four staple crops within the three target countries and marking the rate of improved variety adoption through recurring surveys and comparative analysis.
Vision for change: IMAGE supports inclusive agricultural transformation by providing insights and evidence for seed sector actors to enhance government agency capacity, improve stakeholder coordination, and lead to better resource allocation for varietal development and commercialization.
Project objectives:
Enable a national leadership mandate to monitor crop varieties and adoption
Build a network of technical experts and service providers to provide personalized advisory support
Establish best practices that enable routine monitoring and produce credible results
Form a sustainable funding mechanism based on use cases with government and stakeholder buy-in
Advocate for institutional capacity for reliable monitoring programs
IMAGE provides the opportunity to leverage past monitoring pilots and for cross-country learnings while advancing genetic reference libraries, establishing protocol adoption, and building towards institutionalization over five years. This is done through six objectives:
Comparable estimates of varietal adoption and turnover will be generated and made available to stakeholders
Standardization of best-practices and supporting technologies
Establishment of sustainable business cases
Pilot study results on varietal identity preservation in seed value chains for each country-crop combination
Institutionalized system of varietal monitoring for long-term, sustainable national partner implementation
Generated data used by seed sector stakeholders to make key decisions

For thousands of years, farmers in Afghanistan, Turkey and other countries in the region, have been breeding wheat, working closely with the environment to develop traditional wheat varieties known as landraces. Untouched by scientific breeding, landraces were uniquely adapted to their environment and highly nutritious.
As agriculture became more modernised and intensified, it threatened to push these traditional landraces into extinction, resulting in the loss of valuable genetic diversity. Institutions around the world decided to act, forming germplasm collections known as genebanks to safely house these landraces.
In 2009, a team of wheat scientists from the International Maize and Wheat Improvement Center (CIMMYT), the International Center for Agricultural Research in the Dry Areas (ICARDA), the UN Food and Agriculture Organization (FAO), and national partners set off on a five-year expedition across Central Asia to collect as many landraces as they could find. The project, led by FAO Cereal Breeder and former CIMMYT Principal Scientist Alexey Morgunov, was made possible by the International Treaty on Plant Genetic Resources for Food and Agriculture Benefit-Sharing Fund.
The project had two main missions. The first is to preserve landrace cultivation in three countries, Afghanistan, Turkey and other countries in the region by selecting, purifying, and multiplying the landraces and giving them back to farmers. The second is to scientifically evaluate, characterize and use these landrace varieties in ongoing breeding programmes, exchange the information between the countries, and to deposit the seeds in genebanks to safely preserve them for future generations.
The latest results from the project were published in July in the journal Crops. The study, authored by a team of experts from CIMMYT, ICARDA, FAO, and research institutes in Afghanistan, Turkey and other countries in the region, compared the diversity, performance, and adaptation of the collected wheat landraces with modern varieties grown in the regions using a series of field experiments and cutting-edge genomic tools.
“Landraces are very useful from a breeding perspective because they have been cultivated by farmers over thousands of years and are well adapted to climate change, have strong resistance to abiotic stresses and have very good nutritional quality,” said Rajiv Sharma, a CIMMYT senior scientist and co-author of the paper.
“We were interested in seeing how well landraces adapt to certain environments, how they perform agronomically, and whether they are more diverse than modern varieties grown in these regions – as well as give their improved versions back to farmers before they are lost.”
The experiments, which were carried out in 2018 and 2019 in Turkey, and 2019 in Afghanistan, and other countries in the region revealed several physical characteristics in landraces which are no longer present in modern varieties. For example, the team found striking differences in spike and grain colors with landraces more likely to have red spikes and white grains, and modern varieties tending to have white spikes and red grains. This may have adaptive values for high altitudes and dry conditions.
A surprising finding from the study, however, was that landraces were not more genetically diverse than modern landraces.
“Many people thought that when we went from cultivating landraces to modern varieties, we lost a lot of diversity but genetically speaking, that’s not true. When you look at the genomic profile, modern varieties are just as diverse as landraces, maybe even a little bit more so,” said Sharma.
When the team compared landraces and modern varieties on crop performance, the results were mixed with modern wheat varieties outyielding landraces in half of the environments tested. However, they found that the highest yielding landraces were just as good as the best modern varieties – a reassuring finding for farmers concerned about the productivity of their crops.
A new breeding paradigm
The results of the study have important implications for landrace conservation efforts in farmers’ fields and in future breeding strategies. While crossing wheat landraces with modern varieties to develop improved modern varieties is not new, the authors proposed a novel alternative breeding strategy to encourage the continued cultivation of landraces: improving landraces by crossing them with other landraces.
“In order to maintain landraces, we have to make them competitive and satisfy farmers’ needs and requirements. One option is that we breed landraces,” said Sharma.
“For example, you might have a landrace that is very-high yielding but susceptible to disease. By crossing this variety with another landrace with disease-resistant traits you can develop a new landrace better suited to the farmer and the environment. This approach maintains all the features of landraces – we are simply accelerating the evolution process for farmers to replace the very fast disappearance of these traditional varieties.”
This approach has already been used by crop scientists at the University of California, Davis who has successfully developed and registered “heirloom-like varieties” of dry beans. The varieties trace about 98% of their ancestry to landraces but are resistant to the common mosaic virus.
Heirloom food products are becoming increasingly popular with health-conscious consumers who are willing to pay a higher price for the products, garnering even more interest in conserving traditional landraces.
One of the overarching aims of the project was to give wheat landraces back to farmers and let nature take its course. Throughout the mission, the team multiplied and returned landrace seed to over 1500 farmers in communities across Afghanistan, Turkey and other countries in the region. The team also supplied over 500 farmers with improved landrace seed between 2018 and 2019.
Despite the political turmoil facing these countries, particularly Afghanistan, farmers are still growing wheat and the project’s contribution to food security will continue.
These landraces will take their place once more in the farming landscape, ensuring on-farm wheat diversity and food security for future generations.
This research was conducted with the financial assistance of the European Union within the framework of the Benefit-Sharing Fund project “W2B-PR-41-TURKEY” of the FAO’s International Treaty on Plant Genetic Resources for Food and Agriculture.

An international team of scientists has found that eco-friendly practices such as growing a range of crops, including legumes such as beans or pigeonpea, and adding plant residues or manure to soils can raise food crop yields in places such as rural Africa, where small-scale farmers cannot apply much nitrogen fertilizer.
Published in the science journal Nature Sustainability and examining data from 30 long-running field experiments involving staple crops (wheat, maize, oats, barley, sugar beet, or potato) in Europe and Africa, this major study is the first to compare farm practices that work with nature to increase yields and explore how they interact with fertilizer use and tillage.
“Agriculture is a leading cause of global environmental change but is also very vulnerable to that change,” said Chloe MacLaren, a plant ecologist at Rothamsted Research, UK, and lead author of the paper. “Using cutting-edge statistical methods to distill robust conclusions from divergent field experiment data, we found combinations of farming methods that boost harvests while reducing synthetic fertilizer overuse and other environmentally damaging practices.”
Recognizing that humanity must intensify production on current arable land to feed its rising numbers, the paper advances the concept of “ecological intensification,” meaning farming methods that enhance ecosystem services and complement or substitute for human-made inputs, like chemical fertilizer, to maintain or increase yields.
Boosting crop yields and food security for far-flung smallholders
The dataset included results from six long-term field experiments in southern Africa led by the International Maize and Wheat Improvement Center (CIMMYT). Africa’s farming systems receive on average only 17 kilograms of fertilizer per hectare, compared to more than 180 kilograms per hectare in Europe or close to 600 in China, according to Christian Thierfelder, a CIMMYT cropping systems agronomist and study co-author.
“In places where farmers’ access to fertilizer is limited, such as sub-Saharan Africa or the Central American Highlands, ecological intensification can complement scarce fertilizer resources to increase crop yields, boosting households’ incomes and food security,” Thierfelder explained. “We believe these practices act to increase the supply of nitrogen to crops, which explains their value in low-input agriculture.”
The CIMMYT long-term experiments were carried out under “climate-smart” conservation agriculture practices, which include reduced or no tillage, keeping some crop residues on the soil, and (again) growing a range of crops.
“These maize-based cropping systems showed considerable resilience against climate effects that increasingly threaten smallholders in the Global South,” Thierfelder added.
Benefits beyond yield
Besides boosting crop yields, ecological intensification can cut the environmental and economic costs of productive farming, according to MacLaren.
“Diversifying cropping with legumes can increase profits and decrease nitrogen pollution by reducing the fertilizer requirements of an entire crop rotation, while providing additional high-value food, such as beans,” MacLaren explained. “Crop diversity can also confer resilience to weather variability, increase biodiversity, and suppress weeds, crop pests and pathogens; it’s essential, if farmers are to improve maize production in places like Africa.”
Thierfelder cautioned that widespread adoption of ecological intensification will require strong support from policymakers and society, including establishing functional markets for legume seed and for marketing farmers’ produce, among other policy improvements.
“Dire and worsening global challenges — climate change, soil degradation and fertility declines, and scarcening fresh water — threaten the very survival of humanity,” said Thierfelder. “It is of utmost importance to renovate farming systems and bring us back into a safe operating space.”

As the Russia-Ukraine war continues to degrade global food security, a new analysis lays out concrete actions that governments and investors must do now to mitigate near-term food security risks and stabilize wheat supplies, while transitioning toward long-term resilience.
“The Russia-Ukraine war will impact global food security over months — if not years,” said CIMMYT Global Wheat Program Director and lead author Alison Bentley. “We now need to move beyond defining the problem to implementing practical actions to ensure stable supply, safeguard the livelihoods of millions of vulnerable people and bring resilience to our global agrifood system.”
The war in Ukraine and trade sanctions against Russia are triggering a level of volatility that could easily overwhelm existing mitigation mechanisms. More than 2.5 billion people worldwide consume wheat-based foods; those in lower- to middle-income countries dependent on imports from Russia and Ukraine are particularly affected. Some of the world’s poorest countries, such as Bangladesh, Sudan and Yemen, rely heavily on Russian and Ukrainian wheat. Given the highly interconnected nature of contemporary agrifood systems, few will remain unaffected by this new global food shock.
Mitigate the immediate crisis
The first priority, according to the authors, is to mitigate the immediate crisis by boosting wheat production in existing high- and low-productivity areas, ensuring grain access and blending wheat flour with other low-cost cereals. Bundled agronomic and breeding improvements and sustainable farming practices can reduce dependence on imported grain and fertilizer, while coordinated, multilateral policies can help conserve grain stocks for human consumption and avert trade restrictions.
Increase the resilience of wheat supply
In the medium term, the authors emphasized the need to increase the local, regional, and global resilience of the wheat supply. This can be done by expanding production within agro-ecological boundaries, supporting national wheat self-sufficiency and providing technical assistance, to increase the production of high-yielding disease-resistant wheat and to mainstream capacity for pest and disease monitoring.
Transition to system-level resilience
Finally, to reach crucially needed resilience in the world’s agrifood system, long-term measures must be taken that encompass agroecosystem diversity, address gender disparities in agriculture and rural communities and sustain increased investment in a holistic, agrifood transition.
“The current global food crisis underscores and compounds existing inequalities in our global food system,” Bentley said. “A transition to agrifood system resilience requires us to urgently balance global food supply needs with the multi-layered challenges of climate change, achieving gender equity, nutritional sufficiency and livelihood security.”
The International Maize and Wheat Improvement Center (CIMMYT) is an international organization focused on non-profit agricultural research and training that empowers farmers through science and innovation to nourish the world in the midst of a climate crisis.
Applying high-quality science and strong partnerships, CIMMYT works to achieve a world with healthier and more prosperous people, free from global food crises and with more resilient agrifood systems. CIMMYT’s research brings enhanced productivity and better profits to farmers, mitigates the effects of the climate crisis, and reduces the environmental impact of agriculture.

The G20 Foreign Ministers’ meeting held on July 7-8 in Bali saw Chinese State Councillor and Foreign Minister, Wang Yi, highlight support for CGIAR as part of a proposed cooperation initiative to boost global food security.
Foreign Minister Wang Yi highlighted the need to help CGIAR increase innovation and build cooperation on agricultural science and technology among countries. Addressing the meeting, Wang said the food and energy sectors are crucial for the healthy performance of the world economy and the effective implementation of the UN 2030 Agenda for Sustainable Development.
His statement was made shortly before the signing of Letters of Intent for Cooperation between the Chinese Academy of Agricultural Sciences (CAAS) and two CGIAR Research Centers, the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI).
CIMMYT, IRRI and CAAS intend to establish a joint Center in Hainan to address global food security through advances in wheat and rice breeding. The collaboration aims to enhance the environmental sustainability of rice and wheat based agri-food systems, promote biodiversity conservation, combat climate change, and improve the health and welfare of growers and consumers.
Jean Balié, Regional Director, South East Asia and Pacific, CGIAR, and Director General of IRRI said: “Our new agreement solidifies and updates a longstanding and fruitful partnership. Today we face a different and growing set of challenges to our food, land and water systems, and we welcome the opportunity to strengthen knowledge and information exchange from across CGIAR that will contribute to a transformation of global food, land and water systems.”
CIMMYT Director General, Bram Govaerts added: “This state-of-the-art breeding center will help us develop and deploy the new nutritious, high-yielding and resilient varieties that Asian farmers need to feed and nurture the most populous region of the world sustainably or within planetary boundaries.”
In three decades of collaboration, CAAS and CGIAR have cooperated on germplasm exchange, breeding new varieties of crops, and providing opportunities for staff collaboration, development and training.
In wheat research, the partnership has added as much as 10.7 million tons of grain – worth $3.4 billion – to China’s national wheat output. Additionally,eight CIMMYTscientists have won the Chinese Friendship Award – the highest award for foreign experts who have made outstanding contributions to China’s economic and social progress.
A reaffirmation of Chinese support for CGIAR comes on a tide of growing recognition that more investment is needed to tackle hunger.
Earlier in the year the G7 Foreign Ministers’ Communiqué underlined the urgent need to address risk in global food systems citing this as a top foreign policy objective. At the same time, the G7 Agricultural Ministers Communiqué cautioned that slowing down work to address longer term goals of food systems transformation, in order to address short term food crises, will have negative consequences in the medium and long term. In this context CGIAR’s System Board Chair, Marco Ferroni, recently highlighted the need for world leaders to look at the big picture to solve the food crisis.

“Now more than ever, we need to build greater resilience across our global food system,” said Alison Bentley, Director of Global Wheat Program at the International Maize and Wheat Improvement Center (CIMMYT), to introduce her part of a joint seminar between CIMMYT and WorldFish. The two CGIAR research centers may appear to have different focuses, but the pairing draws attention to many opportunities for intra-CGIAR collaboration to address the looming global food crisis.
Beginning with Ahmed Nasr-Allah, Country Director (Egypt) at WorldFish, the presentation explored Integrated Agriculture and Aquaculture (IAA) systems for food security. Over the coming decades, population growth and increased scarcity of water pose a challenge for food production and agriculture, so water efficiency needs to be maximized.
Nasr-Allah explained that wheat nutrients improve soil quality, which in turn positively impacts fish quality when using water running off growing crops. He gave an example of a farmer who allocated more space on his farm to irrigate and store water and fish, which enabled him to produce higher crop yields. Further research between WorldFish and CIMMYT in this area could be examining nutrient flow from the fish system to the crop system.
Second to present was Bentley, looking at shock-proofing wheat to build future resilience. “It’s important we understand where the risks lie in our global system so we can respond to shocks,” she explained, citing data on global import dependency on Ukrainian and Russian wheat. She went on to describe potential solutions to combat the predicted yield decrease in wheat in the Global South, including substituting a proportion of wheat flour with other under-utilized crops in products, without impacting flour quality or consumer evaluation.
Linking to WorldFish’s work, Bentley highlighted the need to use water more effectively by combining new varieties with enhanced mechanization options to improve crop management, and the potential of optimizing individual components in fish and wheat rotations that could then be combined for greater impact.
The third session was with WorldFish Scientist Sarah Freed, who discussed designing integrated production practices to meet diverse needs. She invited event attendees to consider whether the lessons learnt from challenges in rice growing areas, such as climate change, poverty, food and nutrition insecurity, and increased demand, could be applicable solutions to problems in wheat growing areas.
Using biophysical and sociocultural insights from rice-fish innovations as an example, she listed five recommendations for design: identify objectives; identify a range of production options; use a co-design process; implement fit-for-purpose design and evaluation; and enable adaptation. Of particular interest was the co-design process with people who are involved at all levels, from landowners to rice farmers to laborers, so that the design benefits a variety of stakeholders. Freed also noted that decisions taken for economic reasons, such as extending the shrimp season, can lead to increased soil salinity, which means the ground can no longer incorporate diverse crops.
All three speakers concluded the event by acknowledging the potential in combining their research areas to determine and implement food security solutions.
The Chinese Academy of Agricultural Sciences (CAAS), the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI) are establishing a breeding center in Sanya, Hainan Province, China.
The international cooperation will be conducive to the exploration and utilization of germplasm resources of the research organizations, biological breeding research, technical training, and the innovation of the global seed industry.

CGIAR researchers are taking an innovative approach to analyzing crop and farming systems, by emphasizing nutritional yield. “This is an unusual perspective for an agronomist to apply to our work,” said Timothy Krupnik from the International Maize and Wheat Improvement Center (CIMMYT). “However, farmers in India recognize the critical need to produce more nutritious food that is environmentally sustainable without losing yield levels.”To meet this need, more than 25 researchers from CIMMYT and the Indian Council of Agricultural Research’s Central Soil Salinity Research Institute (ICAR-CSSRI) met from 25-27 May in Karnal, in India’s Haryana state, to plan a collaborative research program on nutrition-smart agriculture.
The program is part of Transforming Agrifood Systems in South Asia (TAFSSA), a CGIAR Regional Integrated Initiative aiming to propel evidence into impact through engagement with public and private partners across the farm production-to-consumption continuum. The Initiative will achieve productive, environmentally-sound agrifood systems that support equitable access to sustainable healthy diets in the world’s most poverty-dense region.
Through three days of workshops, attendees met with more than 200 men and women farmers. They developed a common understanding of the research objectives, designed research for multi-criteria analysis of crop and farming systems with an emphasis on nutritional yield, and developed a joint action plan for data collection and analysis.
To provide attendees with context for the research program, Temina Lalani-Shariff, CIMMYT Regional Director for South Asia, presented an overview of CGIAR activities in India and CGIAR Research Initiatives globally. HS Jat, Principal Scientist (Agronomy) from ICAR-CSSRI also presented some of the institute’s ongoing research and experiments that are examining the effects of different crop rotations on the production of nutritious foods. This included a visit to ICAR-CSSRI’s research trials later in the day.

From the ground up
To improve on the participatory design of research and to tailor the Initiative’s work to on-the-ground needs, the second day of the program was dedicated to visiting farmers in the states of Haryana and Punjab. There, researchers discussed the proposed research priorities and experimental design with the farmers. The design and priorities were later amended based on this feedback.

“This was an incredibly useful workshop for us,” said PC Sharma, Director of ICAR-CSSRI. “This represents a new way of thinking about how to approach crop rotations and production. Having the help of farmers and colleagues in the nutrition community to design our research means we can address multiple issues in one research program. This increases the value of our research and spreads the benefits wider.”
To conclude the workshops, groups presented on their field visits and selected crop rotations and management practices as part of agronomic trial design for nutrition-sensitive and environmentally efficient cropping systems, including consideration of implementation and data collection.

CGIAR together with national, regional, and international partners kicked off the Plant Health and Rapid Response to Protect Food Security and Livelihoods Initiative also known as the Plant Health Initiative in Nairobi, Kenya, on May 12-13, 2022. The Initiative’s inception meeting was fittingly held on the first-ever International Day of Plant Health on May 12 and was attended by over 200 participants (both in-person and virtual), representing diverse institutions.
The Plant Health Initiative targets a broad range of pests and diseases affecting cereals (especially rice, wheat and maize) and legumes such as beans, faba bean, chickpea, lentil, and groundnut; potato; sweet potato; cassava; banana; and other vegetables.
Speaking at the meeting, CGIAR Plant Health Initiative Lead and Director of Global Maize Program at the International Maize and Wheat Improvement Center (CIMMYT) noted that climate change, together with human activities and market globalization, is aggravating challenges to plant health, including outbreaks of devastating insect-pests and diseases. In addition, according to data from the African Union Partnership on Aflatoxin Control in Africa (AUC-PACA), 40 percent of commodities in local African markets exceed allowable levels of mycotoxins in food, causing adverse effects on diverse sectors, including agriculture, human health, and international trade.
“The CGIAR Plant Health Initiative is, therefore, a timely program for strengthening inter-institutional linkages for effective plant health management especially in the low- and middle-income countries in Africa, Asia, and Latin America, said Prasanna. “This calls for synergizing multi-stakeholder efforts to improve diagnostics, monitoring and surveillance, prediction and risk assessment of transboundary pests and pathogens, and implementing integrated pest and disease management in a gender-responsive and socially inclusive manner.”
Demand-driven multistakeholder approach
CGIAR Global Science Director for Resilient Agrifood Systems Martin Kropff reiterated the importance of the Initiative, and emphasized the need for a global plant health research-for-development consortium. He mentioned that all the CGIAR Initiatives, including the Plant Health Initiative, are demand-driven and will work closely with national, regional, and international partners for co-developing and deploying innovative solutions.
The chief guest at the event, Oscar Magenya, Secretary of Research and Innovation at Kenya’s Ministry of Agriculture, pointed out the need for a well-coordinated, multisectoral and multistakeholder approach to managing invasive pests and diseases. He recognized CGIAR’s contribution and partnership with the Government of Kenya through CIMMYT, especially in combating maize lethal necrosis and wheat rust in Kenya.
“As government, we invite the CGIAR Plant Health Initiative to partner with us in implementing the Migratory and Invasive Pests and Weeds Management Strategy that was launched recently [by the Kenya Government],” said Magenya.
Implications of Plant Health in Africa and globally
Zachary Kinuya, Director of Crop Health Program at the Kenya Agricultural and Livestock Research Organisation (KALRO) spoke on the importance of plant health management to African stakeholders, and observed that in addition to improved crop production, food and feed safety must be given adequate priority in Africa.
Director of the Plant Production and Protection Division at the UN Food and Agriculture Organization (FAO), Jingyuan Xia applauded CGIAR for launching the global Initiative. Through his virtual message, Xia stated that the goals of the two organizations are aligned towards supporting farmers and policy makers in making informed decisions and ultimately ending global hunger. He added that the CGIAR has strong research capacity in developing and disseminating new technologies.
CIMMYT Director General Bram Govaerts explained how negative impacts on plant health, combined with climate change effects, can lead to global production losses and food system shocks, including the potential to result in food riots and humanitarian crises. He challenged stakeholders in the meeting to resolve tomorrow’s problems today, through collective and decisive action at all levels.

The German development agency (GIZ) Fund International Agricultural Research (FIA) Advisor Sarah Schmidt said that GIZ supports the Initiative because of its interest in transformative approaches in innovations for sustainable pest and disease management. Recognizing women’s major involvement in farming in Africa, Schmidt said there is a need to empower and equip women with knowledge on plant health as this will result to greater productivity on farms in Africa. “We welcome that the Plant Health Initiative dedicated an entire crosscutting work package to equitable and inclusive scaling of innovations,” she added.
Participants at the launch were also reminded by Ravi Khetarpal, Executive Secretary of the Asia-Pacific Association of Agricultural Research Institutions (APAARI), that the Initiative is now at the critical phase of Implementation and requires diverse actors to tackle different issues in different geographies. Ravi added that biosecurity and plant health are important subjects for the Asia-Pacific region, in view of the emergence of new pests and diseases, and therefore the need to save the region from destructive pest incursions.
Other online speakers at the launch included Harold Roy Macauley, Director General of AfricaRice & CGIAR Regional Director, Eastern and Southern Africa; Nteranya Sanginga, Director General of the International Institute of Tropical Agriculture (IITA) and CGIAR Regional Director, West and Central Africa; and Joaquin Lozano, CGIAR Regional Director, Latin America & the Caribbean.
Reflecting on gender, social inclusion, and plant health
Panel discussions allowed for more in-depth discussion and recommendations for the Initiative to take forward. The panelists delved into the progress and challenges of managing plant health in the Global South, recommending a shift from a reactive to a more proactive approach, with strong public-private partnerships for sustainable outcomes and impacts.
Gender inequities in accessing the plant health innovations were also discussed. The discussion highlighted the need for participatory engagement of women and youth in developing, validating and deploying plant health innovations, a shift in attitudes and policies related to gender in agriculture, and recognition and deliberate actions for gender mainstreaming and social inclusion for attaining the Sustainable Development Goals (SDGs).

Charting the course for the Initiative
The Plant Health Initiative Work Package Leads presented the Initiative’s five specific work packages and reiterated their priorities for the next three years.
“We are looking forward to taking bold action to bring all players together to make a difference in the fields of farmers all over the world,” said Prasanna.

Latin America and the Caribbean possess the largest reserve of arable land on the planet, 30% of renewable water, 46% of tropical forests and 30% of biodiversity. These resources represent an important contribution to the world’s food supply and other ecosystem services. However, climate change and natural disasters, exacerbated by COVID-19, have deteriorated economic and food security, destabilizing communities and causing unprecedented migration, impacting not only the region but the entire world.
Against this regional backdrop, AgriLAC Resiliente was created. This CGIAR Initiative seeks to increase the resilience, sustainability and competitiveness of the region’s agrifood systems and actors. It aims to equip them to meet urgent food security needs, mitigate climate hazards, stabilize communities vulnerable to conflict and reduce forced migration.
Guatemala was selected to present this Initiative, which will also impact farmers in Colombia, El Salvador, Honduras, Mexico, Nicaragua and Peru, and will be supported by national governments, the private sector, civil society, and regional and global donors and partners.
At a workshop on June 27–28, 2022, in Guatemala City, partners consolidated their collaboration by presenting the Initiative and developing a regional roadmap. Workshop participants included representatives from the government of Guatemala, NGOs, international cooperation programs, the private sector, producer associations, and other key stakeholders from the host country. Also at the workshop were the leaders from CGIAR research Centers involved in the Initiative, such as the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT), the International Maize and Wheat Improvement Center (CIMMYT), the International Potato Center (CIP) and the International Food Policy Research Institute (IFPRI).

Impact through partnerships
“Partnerships are the basis for a future of food security for all through the transformation of food systems in the context of a climate crisis. AgriLAC’s goal of a coordinated strategy and regional presence will facilitate strong joint action with partners, donors, and producers, and ensure that CGIAR science continues to be leveraged so that it has the greatest possible impact,” said Joaquín Lozano, CGIAR Regional Director for Latin America and the Caribbean.
This Initiative is one of many CGIAR Initiatives in Latin America and consists of five research components: Climate and nutrition that seeks to use collaborative innovations for climate resilient and nutritious agrifood systems; Digital agriculture through the use of digital and inclusive tools for the creation of actionable knowledge; Low-emission competitiveness focused on agroecosystems, landscapes and value chains that are low in sustainable emissions; Innovation and scaling with the Innova-Hubs network for agrifood innovations and scaling; and finally, Science for timely decision making and establishment of policies, institutions, and investments for resilient, competitive and low-emission agrifood systems.
“We know the important role that smallholder farmers, both women and men, will play in the appropriation of the support tools that the Initiative will offer, which will allow them to make better decisions for the benefit of their communities. That is why one of the greatest impacts we expect from the project will be the contribution to gender equality, the creation of opportunities for youth, and the promotion of social inclusion,” said Carolina González, leader of the Initiative, from the Alliance of Bioversity International and CIAT.
Bram Govaerts, Director General of CIMMYT, said: “In Guatemala, we have had the opportunity to work side by side with farmers who today, more than ever, face the vicious circle of conflict, poverty and climate change. Through this Initiative, we hope to continue making progress in the transformation of agrifood systems in Central America, helping to make agriculture a dignified and satisfying job and a source of prosperity for the region’s producers.”
“I realize the importance of implementing strategic actions designed to improve the livelihoods of farmers. The environmental impact of development without sustainable planning puts at risk the wellbeing of humanity. The Initiatives of this workshop contribute to reducing the vulnerability of both productive systems and farmers and their families. This is an ideal scenario to strengthen alliances that allow for greater impact and respond to the needs of the country and the region,” said Jose Angel Lopez, Guatemala’s Minister of Agriculture, Livestock and Food.

National and regional strategies
AgriLAC Resiliente will also be presented in Honduras, where national partners will learn more about the Initiative and its role in achieving a resilient, sustainable, and competitive Latin America and the Caribbean, that will enable it to achieve the Sustainable Development Goals.
Under the general coordination of CGIAR, other Initiatives are also underway in Guatemala that will synergize with the global research themes toward the transformation of more resilient agrifood systems.
“We are committed to providing a structure that responds to national and regional priorities, needs, and demands. The support of partners, donors and producers will be key to building sustainable and more efficient agrifood systems,” Lozano said.

The UN High Commissioner Michelle Bachelet recently said of Afghanistan, “In the wake of years of conflict, and since the takeover by the Taliban in August last year, the country has been plunged into a deep economic, social, humanitarian and human rights crisis” (UN News 2022a). International humanitarian agencies and NGOs have persisted in supporting the population, half of whom are suffering food insecurity, and some of whom are facing unprecedented and catastrophic levels of hunger (UN News 2022b). The conflict in Ukraine is exacerbating the crises in poor import-dependent countries and humanitarian programmes, and Afghanistan will be among the most affected (Bentley and Donovan 2022).
The rural sector underlies Afghanistan’s economic potential, with agriculture as the foundation of the economy. Wheat, both irrigated and rainfed, is the principal agricultural crop, and bread is the major component of the Afghan diet. For decades the country has relied for food security on neighbors such as Kazakhstan and Pakistan and import dependence appears to be a permanent feature of the agricultural economy (Sharma and Nang 2018).
In a recent paper published in Plants, People, Planet, CIMMYT scientists and partners from SOAS University of London, Afghanistan Research and Evaluation Unit, FAO-Afghanistan, The HALO Trust, Afghanaid and the Agricultural Research Institute of Afghanistan call for renewed investment in Afghanistan’s wheat and agricultural sector.

Improved CIMMYT wheat germplasm has supported agricultural development
CIMMYT’s activities in Afghanistan have focused primarily on supporting the national agricultural research system through the provision of elite, widely adapted germplasm with strong disease resistance. Recent estimates of genetic gains over 14 years (2002-2003 to 2015-2016) of testing of CIMMYT’s Elite Spring Wheat Yield Trial material across 11 locations in Afghanistan documents significant grain yield progress of 115 kg/year. Average yields across 11 testing locations ranged from 3.58 to 5.97 t/ha (Sharma et al., 2021). This indicates that yield potential can be increased through introduction and testing of internationally improved germplasm.
But such investment in research has come to a halt. Local public- and private-sector wheat breeding activities have been largely absent in Afghanistan for over a decade. Hence, wheat productivity remains low due to the limited availability of improved varieties, inadequate quality seed production and distribution. Although in the short term, humanitarian interventions are likely to be the major determinant of food security, we propose that strategic rebuilding of the wheat system will lay the foundation for restoring Afghanistan’s agricultural production, food supplies, nutrition and health. Here we signal opportunities for future improvement.
Opportunities to build climate resilience and enhance seed systems
The need for climate-resilient varieties that meet farmers’ varied requirements and consumer preferences is paramount. Afghan farmers need varieties with improved traits such as heat and drought resilience, incorporating functional variation from existing landrace collections. In addition, agronomic interventions such as conservation agriculture will offer substantial benefits in buffering environmental stresses.
The technological pathways for seed (re-)distribution are a critical part of the innovation pathway from plant breeding to production and productivity. Given the particularities of markets in Afghanistan, both the public sector and the private sector often fail to reach farming geographies that are remote, diverse, and unserved by physical and institutional infrastructure. For many years, basic public services and agricultural interventions have been provided by the NGO sector, and this form of delivery continues. Hence, local ‘informal’ systems for seed and inputs are important to smallholder farmers.
Investment to support both irrigated and rain-fed wheat production
Rehabilitation of ancient irrigation practices and infrastructure could once again serve local farming in a way that supports stable production, restores Afghan heritage, and rebuilds social cohesion. However, there are no easy solutions to the challenges of increasing irrigation to boost agriculture. Although yields are lower, there is potential to optimize breeding specifically for rain-fed production. We expect rain-fed agriculture to continue given the limitations of water and infrastructure access.
Wheat improvement must be embedded in the wider agricultural environment. There is a renewed need for a deep understanding of social, political, and cultural systems and how they vary between villages, and from districts, provinces, and regions to people groups. We need to re-envision the roles of men and women in agriculture, and investment in skills and capacity building to provide a stable foundation for the eradication of poverty and food insecurity.
A new wheat program for Afghanistan
We highlight the urgent need for:
Resumption of breeding of nutritious and climate-resilient varieties.
Development of a knowledge base on current wheat production systems, gendered agricultural roles, farmer needs for varietal change and consumer preferences for tasty and nutritious wheat-based products.
Development of seed information systems using new technologies to enhance farmer engagement in research.
Expansion of appropriate irrigation systems and development of nature-based solutions to protect soil and to preserve and conserve water.
Investment in capacity building among private, non-governmental, university and public stakeholders in seed systems and delivery of agricultural services.
These foundations will support the wider regeneration of Afghanistan’s agricultural sector and enhance food security, nutrition and health of some of the world’s most vulnerable populations.

How does CIMMYT’s improved maize get to the farmer?
CIMMYT is proud to announce a new improved subtropical maize hybrid that is now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across mid-altitudes of Mexico and similar agro-ecologies. National agricultural research systems (NARS) and seed companies are invited to apply for a license to commercialize this new hybrid to bring the benefits of the improved seed to farming communities.
The deadline to submit applications is 15 August 2022. Applications received after that date will be considered during the following round of product allocations.
The newly available CIMMYT maize hybrid, CIM20LAPP2B-2, was identified through rigorous trialing and a stage-gate advancement process that culminated in the 2020 Stage 5 trials for CIMMYT’s Latin American tropical mid-altitude maize breeding pipeline (LA-PP2B). While individual products will vary, the LA-PP2B pipeline aims to develop maize hybrids fitting the product profile described in the following table:

For the first time ever, a biotechnology team has identified vegetative storage proteins (VSP) in maize and activated them in the leaves to stockpile nitrogen reserves for release when plants are hit by drought, which also causes nutrient stress, according to a recent report in Plant Biotechnology Journal. In two years of field testing, the maize hybrids overexpressing the VSP in leaf cells significantly out-yielded the control siblings under managed drought stress applied at the flowering time, according to Kanwarpal Dhugga, a principal scientist at the International Maize and Wheat Improvement Center (CIMMYT).
“One of the two most widely grown crops, maize increasingly suffers from erratic rainfall and scarcer groundwater for irrigation,” Dhugga said. “Under water stress, nitrogen availability to the plant is also attenuated. If excess nitrogen could be stored in the leaves during normal plant growth, it could help expedite the plant’s recovery from unpredictable drought episodes. In our experimental maize hybrids, this particular VSP accumulated to more than 4% in mesophyll cells, which is five times its normal levels, and offered an additional, dispensable source of nitrogen that buffered plants against water deficit stress.”
Dhugga noted as well that the study, whose authors include scientists from Corteva Agriscience, the Bill & Melinda Gates Foundation, and the US Department of Agriculture (USDA), provides experimental evidence for the link between drought tolerance and adequate nitrogen fertilization of crop plants. “This mechanism could also help farmers and consumers in sub-Saharan Africa, where maize is grown on nearly 40 million hectares, accounts for almost one-third of the region’s caloric intake, and frequently faces moderate to severe drought.”
