Theme: Environmental health and biodiversity

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.

CIMMYT project helps educate farmers in Zimbabwe on seed practices and improved varieties

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.

Refresher webinar on fall armyworm management in South Asia

Written by Alison Doody on October 14, 2022. Posted in News.

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.”

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.”

CGIAR Initiative: Plant Health

Written by Sarah McLaughlin on October 11, 2022. Posted in Uncategorized.

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 outbreaks by 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?

Tropentag is an annual interdisciplinary conference on research in tropical and subtropical agriculture, natural resource management and rural development, jointly organized by nine European universities and the Council for Tropical and Subtropical Agricultural Research (ATSAF e.V), in cooperation with the GIZ Fund International Agricultural Research (FIA).

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.

Based on data from CIMMYT’s Accelerating Genetic Gains in Maize and Wheat (AGG) project in Ethiopia, Euler presented a study on how intra-household decision-making dynamics influence the adoption of rust-resistant wheat varieties.

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.

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.

Drought and heat tolerance in bread wheat landraces

Written by Sarah McLaughlin on October 6, 2022. Posted in Publications.

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.

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.

Because error has a price

Written by Alison Doody on October 3, 2022. Posted in Publications.

A systematic review conducted by a team of scientists from the International Maize and Wheat Improvement Center (CIMMYT) has revealed that many farmers around the world incorrectly identify their crop varieties, with significant impacts on their farming practices, yields, profits, and research.

The review, published this month in Outlook on Agriculture, brings together information from 23 published studies to sketch crop variety misclassification among farmers, its determinants, and the implications of classification errors on the farm and in research.

“We found that seven out of ten farmers incorrectly identified the grown variety when they were asked to identify the variety by its specific name. When farmers were asked if the grown variety was either improved or local, three out of ten farmers made incorrect classifications,” said Michael Euler, first author of the study and agricultural resource economist at CIMMYT.

Whether farmers correctly identify crop varieties has a knock-on effect on their farming practices, which in turn affects their crop yields and income. This can bleed into research, impacting experiments and evaluation studies of agricultural technologies and methods. For example, scientists might assign treatment and control groups based on incorrect farmer variety classification, potentially leading to biased estimates and data discrepancies.

“Varietal misidentification can lead to improper agronomic management, forgone farm revenue, and seed system malfunctioning. From a monitoring and evaluation perspective, the potential presence of bias in estimates due to varietal misclassification is problematic as it may mask the true costs and benefits of seed technologies,” said Euler.

The study is the first systematic review of the use of DNA fingerprinting – a method that uses molecular markers to identify crop varieties – to assess how accurate farmers are in identifying their varieties and the impacts this has on seed markets, crop performance, farm profits, and research.

“The use of DNA fingerprinting to identify crop varieties in farmers’ fields has emerged only recently. The review of existing literature, nonetheless, shows its potential to strengthen the functioning and effectiveness of seed markets, supply chains, and extension services,” said Vijesh Krishna, co-author of the study and senior scientist at CIMMYT.

The results of the review show that cases of farmers misidentifying varieties are widespread, causing problems for farm productivity and profits, as well as research. The authors also found that DNA fingerprinting can shed light on what drives farmers to misidentify varieties and how they can minimize misclassification.

“Varietal misidentification is not only related to farmer and farm characteristics but also depends on the properties of the seed system through which seeds are obtained. We need more comprehensive modeling approaches to improve our understanding of the system-level drivers of farmer varietal misclassification,” said co-author and CIMMYT senior agricultural economist Moti Jaleta.

However, like most technologies, DNA fingerprinting has its limitations. It may not always be feasible in all settings, and the costs may offset the benefits in areas where formal seed markets are already well-functioning.

“DNA fingerprinting is considered a reliable method to accurately identify varieties grown by farmers and is increasingly seen as the ‘gold standard’ for varietal identification. However, it requires a high-quality reference library, a well-designed sampling strategy, and accurate tracking of plant samples from collection sites to the point of analysis,” said CIMMYT senior scientist and co-author David Hodson.

Based on the results of the analysis, the authors recommend integrating DNA fingerprinting into existing national data collection toolboxes to accurately estimate adoption and turnover rates of improved crop varieties and to evaluate existing genetic crop diversity on farms. Understanding and promoting genetic crop diversity are crucial steps for enhancing food security and increasing the climate and pest and disease resilience of crops.

Having accurate estimates of adoption and turnover rates of varieties, combined with seed supply system assessment, can also help researchers and decision-makers pinpoint any bottlenecks or loopholes in the “lab to farm” process, according to the authors.

“The review aims at helping researchers and policymakers strategize to more effectively assess the functioning and effectiveness of seed diffusion systems to deliver modern seeds to smallholders,” concluded Krishna.

Weather data and crop disease simulations can power predictions of wheat blast outbreaks, new study shows

Written by Mike Listman on September 26, 2022. Posted in Publications.

Cutting-edge models for crops and crop diseases, boosted by high-resolution climate datasets, could propel the development of early warning systems for wheat blast in Asia, helping to safeguard farmers’ grain supplies and livelihoods from this deadly and mysterious crop disease, according to a recent study by scientists at the International Maize and Wheat Improvement Center (CIMMYT).

Originally from the Americas, wheat blast shocked farmers and experts in 2016 by striking 15,000 hectares of Bangladesh wheat fields, laying waste to a third of the crops. The complex interactions of wheat and the fungus, Magnaporthe oryzae pathotype Triticum (MoT), which causes blast, are not fully understood. Few current wheat varieties carry genetic resistance to it and fungicides only partly control it. Warm temperatures and high humidity favor MoT spore production and spores can fly far on winds and high-altitude currents.

Mean potential wheat blast disease infections (NPI) across Asia, based on disease and crop infection model simulations using air temperature and humidity data from 1980-2019. Black dots represent wheat growing areas with presumably unsuitable climates for wheat blast. The x and y axes indicate longitude and latitude.

“Using a wheat blast infection model with data for Asia air temperatures and humidity during 1980-2019, we found high potential for blast on wheat crops in Bangladesh, Myanmar, and areas of India, whereas the cooler and drier weather in countries such as Afghanistan and Pakistan appear to render their wheat crops as unlikely for MoT establishment,” said Carlo Montes, a CIMMYT agricultural climatologist and first author of the paper, published in the International Journal of Biometeorology. “Our findings and approach are directly relevant for work to strengthen monitoring and forecasting tools for wheat blast and other crop diseases, as well as building farmers’ and agronomists’ disease control capacity.”

Montes emphasized the urgency of those efforts, noting that some 13 million hectares in South Asia are sown to wheat in rotation with rice and nearly all the region’s wheat varieties are susceptible to wheat blast.

MasAgro is “a gift for Africa”

Between June 20-23, the International Maize and Wheat Improvement Center (CIMMYT) hosted its Board of Trustees meeting, with presentations spanning the breadth of its global projects.

One particular project captured the imagination of attendees: MasAgro, which promotes the sustainable intensification of maize- and wheat-based production systems in Mexico. Through implementing collaborative research initiatives, developing improved varieties, and introducing sustainable technologies and farming practices, the program aims to improve livelihoods and production systems for farmers by enhancing their connections with local value chain actors.

Francisco Mayorga, businessman and former Secretary of Agriculture for Mexico, and Lindiwe Sibanda, CIMMYT board member and member of the CGIAR System Board, presented on the creation of CIMMYT’s MasAgro program and its results. Sibanda interviewed Mayorga to learn where the project’s achievements can be scaled and replicated, describing the project as a “gift for Africa” from Mexico.

What’s in it for farmers?

Built on the premise of ‘take it to the farmers’, MasAgro helps farmers understand the broader context of agrifood systems in order to facilitate their successful transition to sustainable farming practices. This is accomplished through innovation hubs: core spaces defined by similar agroecological conditions that promote participatory innovation processes and co-implement functional structures for the validation, adaptation, and scaling of sustainable solutions.

Innovation hubs facilitate mentorship by providing closeness between farmers and value chain actors. A physical and virtual network of research platforms, demonstration modules and extension areas support actors to gain skills and knowledge to achieve common objectives. For example, farmers can learn how about agricultural tools and practices and where best to use them on their land, and they now consider the impact of fertilizers on the soil and ecosystem and seek alternatives.

Useful information is provided via multiple communication tools, including mobile messaging, to enable effective knowledge sharing and innovation between actors. The network has led to farmers independently adapting and adopting new practices after learning from others.

The selling point for farmers is understanding why sustainable agriculture creates opportunities for their livelihoods and lives – with improved practices, they can establish a successful long-term setup to increase their yield and income. These opportunities will appeal to smallholders worldwide.

Benefits for the public and private sector

What also differentiates MasAgro is the emphasis on public and private sector partnerships. CIMMYT collaborated with partners to develop the MasAgro mindset and build their capacity to deliver seed to small- and medium-sized farms. Sibanda praised the use of CIMMYT’s presence in Mexico for developing these connections.

Mayorga highlighted the importance of securing funding and support from the Ministry of Agriculture in the project’s success. He said he initially persuaded colleagues to invest by emphasizing MasAgro’s holistic approach, which considers all elements of farming, rather than dealing with them as individual elements.

Using the different government instruments to support the theory of change towards the impact of MasAgro is part of the success. For example, for businesses, the Mexican government provided funding for laboratory equipment and training needs after identifying seed company partners to support through their research programs and regional markets. Mayorga also celebrated partnerships with small and medium enterprises (SMEs), who were supported by CIMMYT engineers to design more effective machinery and think around scale-appropriate business models. This created additional businesses in the agricultural sector.

Through these partnerships, private sector organizations have invested in agricultural research and development that will benefit smallholders, prevent food insecurity, and support a shift to sustainable farming. Countries in Africa can benefit from similar investment, which could be achieved through exporting and recreating the MasAgro model.

Flexible government support

Practical support and policy change from the Mexican government further encouraged farmers to adopt sustainable practices. Mayorga explained how a subsidy for farmers’ fuel was replaced with alternative financial support for equipment. Sibanda described this initiative as “visionary” and “a triple win” – farmers could purchase a machine at a subsidized rate, use less labor, and cause less damage to the environment.

To incentivize large companies in Mexico that buy a lot of wheat, Mayorga tapped into their desire “to encourage an economic behavior in the farmer” and introduce a more entrepreneurial approach to agriculture. They encouraged businesses to buy grains from farmers at a better price and learn more about the MasAgro approach.

“You don’t stay with an idea as a policy advisor and politician – you popularize it, look for new champions, walk the talk and put money into it,” summarized Sibanda. “I think that’s a legacy.”

Regenerative agriculture in Mexico: the case of Bimbo

Written by Sarah McLaughlin on September 23, 2022. Posted in In the media.

Grupo Bimbo has two pilots with the International Maize and Wheat Improvement Center (CIMMYT) in the Mexican states of Sonora, Sinaloa and Jalisco to embed sustainable practices.

Through regenerative agriculture, an approach which aims to improve soil health and protect water resources and biodiversity, Grupo Bimbo has set the goal of ensuring that 200,000 hectares of wheat are cultivated with regenerative agriculture practices by 2030, ensuring that by 2050 100% of its key ingredients will be produced with this type of practices.

Tracking improved crop varieties

Coordinating the development and deployment of improved seed varieties is a complex task involving many stakeholders, including government agencies, public and private seed sector organizations, and ultimately, farmers and farmer groups. Cooperation among these groups is vital to assess and measure the impact of improved varieties and to guide decision making for future crop breeding efforts.

The Institutionalizing Monitoring of Crop Variety Adoption using Genotyping (IMAGE) project, funded by the Bill & Melinda Gates Foundation and managed by Context Global Development, is a five-year program operating in Nigeria, Tanzania, and Ethiopia designed to increase the efficacy of variety deployment by establishing, institutionalizing, and scaling up routine monitoring of improved variety adoption and turnover using genotyping technologies, focusing on wheat, maize, teff, and the common bean.

The International Center for Maize and Wheat Improvement (CIMMYT), in collaboration with the Ethiopian Institute of Agricultural Research (EIAR), launched Ethiopia’s IMAGE National Advisory Committee (NAC) February 25, 2022, in Addis Ababa.

Feto Esemo, the Director General of the Ethiopian Institute of Agricultural Research (EIAR) officially opened the workshop.

Esemo underscored in his opening remarks the NAC’s mission to promote the application of DNA fingerprinting for an accurate assessment and understanding of the adoption of improved maize and wheat varieties by small-holder farmers in Ethiopia and resolve data discrepancy among researchers.

The NAC is the highest advisory body for IMAGE’s implementation in Ethiopia and comprises seven institutions: Ministry of Agriculture (MoA), Ministry of Planning and Development (MPD), Agricultural Transformation Institute (ATI), EIAR, Central Statistical Agency (CSA), Ethiopian Biodiversity Institute (BI), and the Ethiopian Biotechnology Institute (EBI).

Kindie Tesfaye, CIMMYT senior scientist, emphasized the application of DNA fingerprint data on maize and wheat in Ethiopia and summarized the IMAGE Project.

“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,” said Tesfaye.

He added the IMAGE Project provides the opportunity to leverage past monitoring pilots and cross-country lessons while advancing genetic reference libraries, establishing protocol adoption, and building towards institutionalization over five years.

National maize and wheat genotyping studies in Ethiopia proved the feasibility of using DNA fingerprinting for variety monitoring at scale and CIMMYT and EIAR presented the findings to seed system and policy stakeholders with an emphasis on demonstrating how varietal identity based on genotyping compares with farmers’ elicitation, the area-weighted average age of varieties, germplasm attribution, and varietal performance.

Chilot Yirga, Deputy Director-General, Capacity Building and Administration of EIAR, emphasized the functional and structural roles of the National Advisory Committee (NAC), Country Team (CT), and Technical Working Group (TWG) of the project in the country.

EIAR, the Holetta National Agricultural Biotechnology Research Center, CSA, and CIMMYT comprise the Country Team.

Yirga also briefed the participants on the details of the Committee’s mandate and indicated the roles of all stakeholders and policymakers, specifically in DNA fingerprinting.

The workshop concluded by electing a chairperson and vice-chairperson of the committee among its members and co-project leaders from CIMMYT and EIAR.

Written by Sarah McLaughlin on September 9, 2022. Posted in News.

This year’s Borlaug Global Rust Initiative (BGRI) Gene Stewardship Award recipients have been recognized for their innovative research tackling the global problem of wheat leaf rust.Led by Julio Huerta from the Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP), members of the award-winning team include:

Héctor Eduardo Villaseñor Mir (cereal breeder)
René Hortelano Santa Rosa (cereal breeder)
Eliel Martínez Cruz, (cereal chemist)
María Florencia Rodríguez García (cereal pathologist)
Ernesto Solís Moya (wheat breeder)
Jorge Iván Alvarado Padilla (wheat breeder)

The award recognizes the team’s long-term contribution to Mexican wheat cultivation and their efforts to expand impacts worldwide. They have released many varieties with resistance to leaf rust, which has led to the stabilization of the disease in bread wheat.

Presented annually, the award is bestowed upon a team of researchers serving a national breeding program or other nationally based institution. Winners receive an inscribed bronze statue of Norman Borlaug.

Huerta has been hosted by the International Maize and Wheat Improvement Center (CIMMYT) in Mexico since the late 1990s.

BGRI Technical Workshop

Receiving the prize at the 2022 BGRI Technical Workshop on September 9, Huerta said, “The award means a recognition from the global rust scientific community for the hard work (flesh, mind, soul and spirit) over the years, carried with many colleagues around the world to keep rust disease under control.”

Alison Bentley, director of the Global Wheat Program, also participated in the event with a presentation on the connection between conflict and vulnerability in global food systems. She explored reasons why wheat has been dramatically impacted by the conflict in Ukraine and summarized the proposed response agenda by CIMMYT.

Ravi Singh, head of wheat improvement and rust research at the International Maize and Wheat Improvement Center (CIMMYT), received the Sh. VS Mathur Memorial Award 2022 for outstanding contribution in the field of wheat crop improvement from the Society for Advancement of Wheat and Barley Research (SAWBAR).

Singh received the award from T. R. Sharma, Deputy Director General of the Indian Council of Agricultural Research (ICAR) and G. P. Singh, Director of the Indian Institute for Wheat and Barley Research (IIWBR) at ICAR.

As recipient of the award, Singh delivered a lecture during the 61^st All India Wheat and Barley Research Workers’ Meet in Gwalior, India, on August 29. He highlighted and praised the partnership between India and CIMMYT as essential for accelerating gains in wheat yield despite the stresses of climate change thanks to improved resilience in new varieties and earlier sowing.

“The ICAR-CIMMYT wheat improvement partnership remains crucial for delivering new varieties with higher rates of genetic gain in farmers’ fields to enhance productivity, climate resilience, disease resistance and nutrition while meeting market needs,” he said.

Successes of the partnership include integrated breeding with a common agenda, commercialized varieties that are adapted to flexible sowing dates including early sowing, diverse and durable resistance to rust diseases, adoption of wheat blast resistant varieties in large areas, biofortified and high-quality varieties, and the move towards mainstreaming of zinc (Zn) biofortification.

Singh also paid homage to the award’s namesake, as VS Mathur’s “wheat varieties once occupied fields of many millions of farmers and provided food and nutrition to many more millions throughout India and beyond”.
