Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

African smallholder farmers hit hard by global food shortage: expert

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

At the 2023 Dryland Legumes and Cereals Review and Planning Meeting, Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), explained why African smallholder farmer families are most impacted by food shortages and high food prices.

“The world is in the middle of a food crisis, driven by the supply chain disruptions during and post-Covid, climate change with increased storms, temperatures, and drought, and the Russia-Ukraine crisis, leading to a shortage of fertilizers for food crop production, which have all led to the high cost of food,” said Govaerts, highlighting that smallholders are dealing with multiple challenges at once.

He continued by describing how the aforementioned challenges to food security are worsening poverty for vulnerable people in Africa, especially smallholder farmers.

However, harnessing the continent’s potential for food production could help to alleviate poverty and food insecurity. Govaerts cited examples of where smallholder farmers have returned to producing nutritious indigenous crops such as millet, sorghum, guinea corn, groundnut, cowpeas and chickpeas, which are reaping tremendous results.

Through investments in crops, farming practices, and agricultural technologies, the potential for food production in Africa can have a huge impact on hunger and poverty.

Staple commodities: Country can save $1.3bn annually by developing efficient storage system

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

Farmers in Pakistan could save up to $1.3 billion each year in post-harvest losses with the development of an efficient storage system.

Research shows that inefficient storage is the main cause of staple commodity losses in the country. Despite producing 27 million tons of wheat annually worth $7.4 billion, there is less than 6 million tons of storage capacity available; around 10% of the surplus wheat is lost at a value of $740 million due to the use of unregulated conditions.

With the ability to store their commodity for an extra two or three months, farmers can increase their income by between 20 to 40 percent. Preserving the crops that have already been produced will also pass on a saving of between 15 to 20 percent to end consumers.

Hermetic technology developed by the International Maize and Wheat Improvement Center (CIMMYT), the International Rice Research Institute (IRRI) and the University of Hohenheim offers a potential storage solution by protecting the commodity from the ambient environment.

Farmers harvested double yield by adopting Wengkhar Hybrid Maize 1 in Bhutan

Written by Sarah McLaughlin on . Posted in Features.

The planting of maize hybrid Wengkhar Hybrid Maize 1 (WHM-1) has helped farmers in the Mongar district of Bhutan double their maize yield.

WHM-1 was developed in partnership with the International Maize and Wheat Improvement Center (CIMMYT) and became the first maize hybrid to be released in Bhutan to combat the negative effect of increasing temperature or extreme heat events on maize.

The hybrid was designed with characteristics of heat and drought tolerance, as well as a resistance to stem and root lodging. It also had additional stay-green traits after cob maturity and produced a high yield.

The success of the implementation in Bhutan is leading to an increased production of WHM-1, which will aim to meet national demand and work towards country’s self-sufficiency.

Dechen Yangden is one of the smallholder beneficiaries in Tsakaling, a sub-district in Mongar in the east of the country, who have boosted their maize yield by planting WHM-1. “My attempt to grow WHM-1 has doubled my maize production compared to last season where I cultivated some other maize varieties (2.5 metric tons (mt) in one hectare (ha)),” she said.

Farmers’ experiences of WHM-1

Since its official release in 2020, the national maize program based at Agriculture Research & Development Center (ARDC) started producing hybrid seeds and maintaining parental lines. To test the success of the ARDC’s work, planting was carried out in the Tsakaling and Waichur hamlets in Mongar districts, covering an area of six acres.

Maize farmers in Tsakaling shared that although the crop was affected by the insect fall armyworm during the early vegetative stage, the productivity of the crop was not affected, as it recovered at later stage.

Meanwhile, ARDSC Khangma carried out yield monitoring during the harvest, where WHM-1 yielded 5.8 mt ha-1, which is noticeable rise on the national average of 3.7 mt ha-1.

Following the conclusion of their harvest, farmers in the two localities shared their views on the newly released maize in order to review the effect of the implementation of WHM-1. Both sets of growers reported an improved performance from the use of WHM-1 and noted that, unlike other maize varieties, the hybrid has shorter and uniform plant height along with a higher resistance to lodging, which is an essential trait given the conditions it is grown in. Furthermore, the stay-green trait of the hybrid after maturity of cobs gave farmers an added advantage of green fodder, which can be used for feeding their cattle.

In Waichur, the growers found that this hybrid had a tight husk and fully filled kernels. They shared similar views to growers in Tsakaling, reporting positive lodging resistance in the hybrid.

Both communities expressed their interest in continuing to use WHM-1, given the availability and accessibility of the seeds. As a response, the National Maize Program at ARDC Wengkhar, is looking to deploy the newly released hybrid on a larger scale, which will ultimately contribute towards enhancing maize self-sufficiency in the country.

WHM-1 was developed through partnership of the National Maize Program at Wengkhar and CIMMYT under the Heat Stress Tolerant Maize for Asia (HTMA) project for germplasm and technical assistance and the Commercial Agriculture and Resilient Livelihoods Enhancement Program (CARLEP-IFAD/MoAF) for on-farm research and intensification.

Feasibility mapping for WHM-1 showed that its adaption stretches along the southern foothills and some parts of eastern district. The National Maize Program, sister research centers, and farmers are currently working on upscaling the seed production for intensification of national maize production to meet the domestic demands.

Five strides forward for CGIAR crop breeding resources and services

Written by Sarah McLaughlin on . Posted in News.

Sitting at the cutting edge of science, the crop breeding domain has been improving and refining tools, technologies and techniques. But adoption by public breeding programs focusing on Africa, Asia, and Latin America has often been slow. This has hindered progress on developing the new varieties needed for farmers to overcome climate impacts, build livelihoods, and feed their communities.

But One CGIAR’s new integrated approach is changing that. Building on the work of CGIAR Excellence in Breeding, the Breeding Resource Initiative can point to major progress in 2022, moving forward on an array of shared services, capacity development programs and technical support. Here are five significant milestones helping CGIAR and its national partners deliver better results:

1. Regional hubs are on their way: CGIAR’s vision is to have regional hubs coordinating and delivering services across crops. AfricaRice is set to grow into a regional service provider and coordinator for multiple crops in West Africa. After discussions, planning and site visits with BRI, AfricaRice leadership committed to working with the BRI team to start by providing regional nutritional analysis services, aimed to launch for selected partners in 2023. The plan is to then expand AfricaRice’s role as a coordinator of other competitive services like genotyping and capacity building. This is a major step toward CGIAR’s vision of not just improving breeding stations, but serving  all CGIAR/National Agricultural Research and Extension Services (NARES) partners regionally. The aim is collaboration, efficiency and results in farmers’ fields.

2. Operations teams are amping up skills and knowledge: Breeding success hinges on good operational practices leading to accurate data. To ensure the heritability of breeding trials, BRI has offered resources, trainings and on-the-ground support for operational teams. Through its Breeding Operation Network for Development (BOND), BRI/EiB, along with IITA, ran three weeklong workshops for partners across Africa (watch all 22 sessions on plotmanship, gender, seed processing, irrigation and more), regular webinars exploring private and public sector best practices, and a series focusing on continuous improvement approaches. BRI also trained dozens of operational staff across Africa on how to use and maintain new USAID-supplied equipment. And CGIAR continued its push to harmonize rice breeding processes between IRRI, AfricaRice and CIAT through a week-long rice breeding operations training at IRRI. As well, new tools such as a gender inclusion checklist are now available to support operational excellence.

3. EBS is settling in as a universal data platform: The data management platform Enterprise Breeding System has made real strides in the past year, with an updated version with new features (Milestone 5) rolling out across three Centers (CIMMYT, IITA, IRRI), with over 500 users. Other Centers, such as AfricaRice are starting to deploy the system too. On their visit to AfricaRice’s Ivory Coast station, the BRI team noted barcode deployment across the upland rice nurseries – an inspiration to spur other CGIAR Centers to accelerate their own adoption. EBS is a single, powerful, shared, multi-crop platform and its deployment will mean major time and money savings for breeders – and better breeding decisions.

4. Lab services are expanding: As breeders strive for higher-yielding, climate-resilient and nutritious crops, BRI/EiB have been improving breeding speed and accuracy through streamlined, reliable and cost-effective genotyping services. Services include Low Density SNP Genotyping Services (LDSG), Mid-density SNP Genotyping (MDSG), along with training. BRI also launched a Lab Services Process Team to connect Genetic Innovation departments and teams and ensure delivery of high quality services through standardized processes. And launching in 2023, partners will be able to access biochemical testing for nutritional traits and quality. These improved services mean CGIAR and national partners are becoming more effective and competitive as they use this data to make better decisions.

5. Regional approaches set to drive change: BRI drives change at both local and regional levels. For example, team members visited Kiboko and Njoro stations in Kenya, and ran planning sessions in Nairobi with East African breeding teams. This helped clarify challenges and priorities in the region, helping define how services could best be established. Kenya’s key outcomes included: a commitment with CIMMYT leadership to establish services in Kiboko as a pilot, an action plan to improve EBS development and adoption in the region, and endorsement by CGIAR Breeding Research Services leadership of major Crops to End Hunger grants in the region – these fill key gaps in the drive to modernization. The team plans to organize similar sessions to support CGIAR/NARES breeding networks in other regions.

These five strides forward represent but a glimpse into Breeding Resources’ progress. And these are much more than just separate achievements. They represent a shift in breeding culture across the CGIAR-NARES networks – one that will help deliver better varieties, faster. With major plans for 2023, CGIAR-NARES can look forward to the tools and services they need to deliver first-class programs.

More than a drop in the bucket: addressing food security in Nepal through improved sustainable irrigation

Written by Nur-A-Mahajabin Khan on . Posted in Features.

Agriculture is always impacted by war. However, Russia’s war in Ukraine, fought between two major agricultural producers in an era of globalized markets, poses unprecedented implications for global agriculture and food security. Russia and Ukraine are significant exporters of maize, wheat, fertilizers, edible oils and crude oil. These exports have been compromised by the war, with the greatest impact being on poor and low-income countries that rely most on food imports. Partly because of the Ukraine-Russia conflict and partly due to the decline in agricultural production caused by the climate emergency, food prices have increased between 9.5 and 10.5 percent over the past ten years. 

Nepal, where one in four families is impoverished, is an example of a low-income country impacted by the war’s disruption of trade in agricultural goods and inputs. Although wheat, maize and rice are staples, vegetables are also important for nutrition and income, and Nepal imports fuel and fertilizer for their domestic production. Uncertainty in global supply chains, combined with the Nepali rupee’s significant depreciation against the US dollar, has resulted in a 500% increase in the cost of diesel since 2012. ­­

Irrigation to boost homegrown production

Land irrigation is crucial to crop growth and to the capacity of famers to withstand the effects of the climate emergency and economic shock. However, the majority of Nepal’s groundwater resources are underutilized, leaving ample room for increasing climate-resilient agricultural production capable of withstanding an increasing number of drought events. With the right kind of management of its groundwater, Nepal can increase its domestic output, and bolster smallholder resilience and food security in times of economic and climate crisis.

As part of the first prong of this approach, the Cereal Systems Initiative for South Asia (CSISA) advises farmers (particularly women), governments and donors on the targeted support available to enable them to access existing low-cost and fuel-efficient engineering solutions. These solutions can contribute to the immediate goals of increasing agricultural productivity, intensifying groundwater irrigation and improving rural livelihoods. CSISA informs small producers about ways to access irrigation and develop water entrepreneurship. It also and empowers farmers, especially women, to improve service provision and gain access to services and irrigation pumps, including through access to finance.

Policymakers, businesses, researchers and farmers (especially women, youth and marginalized groups) will collaborate to co-create business models for sustainable and inclusive irrigation with development partners and Nepali public and private sector actors. While there are more than one million wells and pumps in Nepal, many of these are not used efficiently, and social barriers often preclude farmers from accessing services such as pump rentals when they need them. To address these constraints and support private investment in irrigation and water entrepreneurship models, CSISA will work with existing infrastructure investment programs and local stakeholders to build a dynamic and more inclusive irrigation sector over the course of the next year, positively impacting a projected 20,000 small farming households.

At the macro-level, these water entrepreneurship models will respond to prioritized irrigation scaling opportunities, while at the farm level they will respond to irrigation application scheduling advisories. CSISA will also create policy brief documents, in the form of an improved farm management advisory, to be distributed widely among partners and disseminated among farmers to support increases in production and resilience. CSISA’s sustainable and inclusive irrigation framework guides its crisis response.

Scaling digital groundwater monitoring to support adaptive water management

In growing resilience-building irrigation investments, there is always a risk of groundwater depletion, which means that accurate and efficient groundwater data collection is vital. However, Nepal doesn’t currently have a data or governance system for monitoring the impact of irrigation on groundwater resources.

To tackle the need for low-cost, context-specific data systems which improve groundwater data collection, as well as mechanisms for the translation of data into actionable information, and in response to farmer, cooperative and government agency stakeholder demands, the Government of Nepal Groundwater Resources Development Board (GWRDB) and CSISA have co-developed and piloted a digital groundwater monitoring system for Nepal.

In a recent ministerial level workshop, GWRDB executive director Bishnu Belbase said, “CSISA support for groundwater monitoring as well as the ongoing support for boosting sustainable and inclusive investments in groundwater irrigation are cornerstone to the country’s development efforts.”

A pilot study conducted jointly by the two organizations in 2021 identified several options for upgrading groundwater monitoring systems. Three approaches were piloted, and a phone-based monitoring system with a dashboard was evaluated and endorsed as the best fit for Nepal. To ensure the sustainability of the national response to the production crisis, the project will extend government monitoring to cover at least five Tarai districts within the Feed the Future Zone of Influence, collecting data on a total of 100 wells and conducting an assessment of potential network expansion in Nepal’s broad, inner-Tarai valleys and Mid-Hills regions. The goal is to utilize this data to strengthen the Feed the Future Zone of Influence in Nepal by increasing GWRDB’s capability to monitor groundwater in five districts.

Ensuring food security

These activities will be continued for next two years. During that time CSISA will increase GWRDB’s capacity to monitor groundwater and apply this to five districts in Nepal’s Feed the Future Zone of Influence, using an enhanced monitoring system which will assist planners and decision-makers in developing groundwater management plans. As a result, CSISA expects to support at least 20,000 farming households in gaining better irrigation access to achieve high yields and climate-resilient production, with 40 percent of them being women, youth and/or marginalized groups. This access will be made possible through the involvement of the private sector, as CSISA will develop at least two promising business models for sustainable and inclusive irrigation. Finally, through this activity government and private sector stakeholders in Western Nepal will have increased their capacity for inclusive irrigation and agricultural value chain development.

CSISA’s Ukraine Response Activities towards boosting sustainable and inclusive irrigation not only respond to crucial issues and challenges in Nepal, but will also contribute to the regional knowledge base for irrigation investments. Many regions in South Asia face similar challenges and the experience gained from this investment in Nepal will be applicable across the region. Given the importance of of groundwater resources for new farming systems and food system transformation, the project is mapped to Transforming Agrifood Systems in South Asia (TAFSSA), the One CGIAR regional integrated initiative for South Asia, that will act as a scaling platform for sharing lessons learned and coordinating with stakeholder regionally towards more sustainable groundwater management and irrigation investments.

Pravasi Bharatiya Samman winner, scientist Dr Ravi Singh is working towards food security for all

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

As he retires from his illustrious career, a new interview with Ravi Singh, Head of Global Wheat Improvement at CIMMYT, by the Global Indian reveals his motivations for becoming a scientist and his desire to ensure people all over the world had access to food.

“I retired quite recently, however, I have a lot to do. I wish to mentor young scientists about on how to increase food production. I also look forward to working on several high-profile projects with farmers to tackle future issues they might face due to the climate changes on a crop like wheat,” shares the scientist.

Singh was honored with the Pravasi Bharatiya Samman by the Government of India in January 2021, recognizing his outstanding achievements by non-resident Indians, persons of Indian origin, or organizations or institutions run by them either in India or abroad. He received this for his role in the development, release, and cultivation of more than 550 wheat varieties over the past three decades.

Singh has also been included among the top one percent of highly-cited researchers, according to Clarivate Analytics-Web of Science every year since 2017.

Digital Press Briefing with U.S. Special Envoy for Global Food Security Dr. Cary Fowler, and USAID Global Food Crisis Coordinator Dina Esposito

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

Cary Fowler, Special Envoy for Global Food Security, and Dina Esposito, the United States Agency for International Development (USAID) Global Food Crisis Coordinator, discussed the US strategy for addressing the global food security crisis and their ongoing visit to Malawi and Zambia at a digital press briefing on January 19.

“We’ve recently supported a new project which will be operating in a number of countries, including Zambia and Malawi, that will be coordinated by the International Maize and Wheat Improvement Center, and by the International Institute of Tropical Agriculture,” said Fowler.

“They’ll be establishing innovation hubs where they’ll bring together the best and most appropriate technologies and information to help small-scale farmers with a whole variety of issues that they confront. This will give the farmers access, for example in Zambia, to drought-tolerant maize, which they’re really clamoring for. This is maize which, on a year-in and year-out basis, on average will yield about 30 percent more, rotated with legumes, which provide protein and also enrich the soil and reduce the need for fertilizer. But also other technologies and assistance in establishing markets for those products and lengthening out the value chain so that farmers are not just – and small businesses are not just dealing with raw commodities but are taking those commodities and making something more valuable and more useful to a broader population.”

Closing the investment gap for sustainable agriculture

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

The conflict between Russia and Ukraine has impacted exports of wheat, barley and fertilizers, affecting food security in many regions that rely heavily on imports to access these products. The UN Food and Agricultural Organization (FAO) and the World Food Programme predict that acute food insecurity will affect up to 205 million people by early 2023, with conditions deteriorating further in 19 countries.

Redesigning agricultural systems to solve this challenge must also take climate change into account: research published in Nature Food suggests that food systems cause a third of global greenhouse gas (GHG), while use and misuse of fertilizers, pesticides, energy, and water damages biodiversity.

The private sector is missing out on opportunities to invest in the agricultural sector and be part of the solution due to the challenges of putting a price on something like ‘protecting biodiversity’.

Director of CIMMYT’s global wheat program Alison Bentley says that while overseas development assistance and national governments provide significant support to the organization, private finance does play a role. “We have some really nice collaborations with the private sector, which allow us to access technology. The private sector, in the space of plant genetics and plant breeding, has pioneered some methodologies and technologies,” she tells GTR.

Exotic wheat DNA helps breed ‘climate-proof’ crops

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

A new study has determined that wheat with exotic DNA from wild relatives benefits from up to 50 percent higher yields in hot weather, compared with elite lacks lacking these genes.

The study by the International Maize and Wheat Improvement Center (CIMMYT) and the Earlham Institute examined how exotic alleles contribute to wheat heat tolerance in different field conditions based on field trials in Sonora, Mexico.

“Crossing elite lines with exotic material has its challenges,” said Matthew Reynolds, co-author of the study and leader of Wheat Physiology at CIMMYT. “There’s a well-recognized risk of bringing in more undesirable than desirable traits, so this result represents a significant breakthrough in overcoming that barrier and the continued utilization of genetic resources to boost climate resilience.”

These results can be used to improve crop resilience and food security in the face of the challenges posed by climate change, as well as emphasizing the importance of genetic diversity in key crops where selective breeding has reduced adaptability.

Mexico Agriculture: Thrive on the Shift from Efficiency to Resiliency

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

In an interview, Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), highlights the challenges facing crop cultivation management and agricultural product trade in Mexico and the rest of the world.

“At present, one of the most pressing challenges [in Mexico] is water scarcity exacerbated by la Niña’s occurrence,” explains Govaerts. “The global average of freshwater consumption for food production is 70 percent. However, Mexico ranks 24 in a global Water Stress Index facing high levels of stress by consuming between 40 and 80 percent of water supplies available in any given year.”

The article explores successful local sustainable grain sourcing projects in Mexico, research into sustainable global agricultural development, genetically-modified crops and their connection to biodiversity, and soil health.

A sustainable solution to micronutrient deficiency

Written by Sarah McLaughlin on . Posted in Publications.

Zinc deficiency affects one third of the global population; vitamin A deficiency is a prevalent public health issue in many parts of sub-Saharan Africa and South Asia. This includes countries like Nepal, where alarming rates of micronutrient deficiency contribute to a host of health problems across different age groups, such as stunting, weakened immune systems, and increased maternal and child mortality.

In the absence of affordable options for dietary diversification, food fortification, or nutrient supplementation, crop biofortification remains one of the most sustainable solutions to reducing micronutrient deficiency in the developing world.

After a 2016 national micronutrient status survey highlighted the prevalence of zinc and vitamin A deficiency among rural communities in Nepal’s mountainous western provinces, a team of researchers from the Nepal Agricultural Research Council and the International Maize and Wheat Improvement Center (CIMMYT) proposed a study to assess the yield performance of zinc and provitamin A enriched maize varieties.

Focusing on the river basin area of Karnali Province — where maize is the staple food crop for most people – they conducted two different field trials using an alpha lattice design to identify zinc and provitamin A biofortified maize genotypes consistent and competitive in performance over the contrasting seasons of February to July and August to February.

The study, recently published in Plants, compared the performance of newly introduced maize genotypes with local varieties, focusing on overall agro-morphology, yield, and micronutrient content. In addition to recording higher levels of kernel zinc and total carotenoid, it found that several of the provitamin A and zinc biofortified genotypes exhibited greater yield consistency across different environments compared to the widely grown normal maize varieties.

The results suggest that these genotypes could be effective tools in combatting micronutrient deficiency in the area, thus reducing hidden hunger, as well as enhancing feed nutrient value for the poultry sector, where micronutrient rich maize is highly desired.

“One in three children under the age of five in Nepal and half of the children in the study area are undernourished. Introduction and dissemination of biofortified maize seeds and varieties will help to mitigate the intricate web of food and nutritional insecurity, especially among women and children,” said AbduRahman Beshir, CIMMYT’s seed systems specialist for Asia and the co-author of the publication. Strengthening such products development initiatives and enhancing quality seed delivery pathways will foster sustainable production and value chains of biofortified crops, added Beshir.

More than 20 participants attended the genetic resources and seed production courses given by researchers from the Global Maize Program of the International Maize and Wheat Improvement Center (CIMMYT), from October 24 to 28 in Antigua, Guatemala. Among the attendees were technicians and researchers from the Institute of Agricultural Science and Technology (ICTA, for its acronym in Spanish), as well as students from Universidad Rafael Landívar and the University Centers of Chimaltenango (CUNDECH, in Spanish) and Quiché (CUSACQ, in Spanish) of Universidad de San Carlos de Guatemala.

Thanks to the support of the Global Environment Facility (GEF), the Tropical Agricultural Research and Higher Education Center (CATIE, in Spanish), the National Council for Protected Areas (CONAP, in Spanish) and the United Nations Environment Program (UNEP), these courses contributed to the development of a biosafety project, supported by GEF and UNEP, to complete the implementation process of the Cartagena Protocol through an innovative approach that promotes a strong link between biotechnology and biodiversity. In addition, it sought to strengthen capacities in the performance and interpretation of molecular analyses and promote the generational change that is gradually taking place in this Central American country.

Activities began on October 24 and 25 with the course on Statistics Applied to Genetic Resources given by Juan Burgueño, Head of CIMMYT’s Biometrics and Statistics Unit, to students from the aforementioned universities and ICTA staff interested in the analysis of molecular data for the purpose of characterizing accessions and the formation of core collections in germplasm banks. On the 26 and 27 of the same month, CĂ©sar Petroli, a specialist in high-throughput genotyping at CIMMYT, offered a course on biotechnology and high-throughput genotyping.

At the same time, Alberto Chassaigne, curator of the Maize Collection of CIMMYT’s germplasm bank, participated in the course on Genetic Resources and Management of Germplasm Banks. He explained the management of CIMMYT’s germplasm bank, the processes that are carried out and the partnerships with ICTA on work with community seed banks and the plans of both institutions for 2023. Also, as a specialist in Seed Systems, Chassaigne and Ubaldo Marcos, research assistant in CIMMYT’s Maize Seed Systems area, gave a course on Maize Seed Production. This course was aimed at staff in charge of the production of basic and certified seed at ICTA. This course concluded with a field day at the Regional Research Center of the South (CISUR, in Spanish), Cuyuta, Escuintla, where participants asked the specialists questions while visiting a maize seed production plot.

In turn, María de los Ángeles Mérida, a researcher specializing in genetic resources from ICTA, who organized these courses, spoke about the collection and conservation of native varieties of maize in Guatemala. Additionally, César Azurdia, CONAP biodiversity advisor, gave a presentation on wild relatives of different crops in Guatemala. Leslie Melisa Ojeda C. (CONAP) also participated, and spoke about the issue of legislation on crop wild relatives; and, Mynor Otzoy, a researcher from Universidad de San Carlos de Guatemala, spoke about the collection and morphological characterization of cocoa germplasm in Guatemala.

Along the path of constant strengthening of collaboration ties with countries, course participants highlighted their interest and need to continue this type of training. In 2023, it is expected to facilitate a team training with Ubaldo Marcos and FĂ©lix San Vicente, CIMMYT maize breeder for Latin America. It should be noted that, within the framework of the CGIAR germplasm bank initiative, the objective will be to replicate this experience in other Latin American countries and increase participation in community seed banks (ex situ and in situ banks).

Rear fish in a rice paddy? Old ways can future-proof food production

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

In an op-ed for the South China Morning Post, Bram Govaerts, Director General at the International Maize and Wheat Improvement Center (CIMMYT), and Essam Yassin Mohammed, Interim Director General of WorldFish and acting Senior Director of Aquatic Food Systems of CGIAR, explore the role of the research community in developing future-proof strategies to address challenges to the global agrifood system.

Through examples from Egypt, Malaysia and Mexico, the authors explain the benefits of “co-culture”, such as when different crop species are grown together.

This innovation centers on co-design, combining farmer-centric models and new measurement tools that allow scientific advances to benefit a variety of smallholder production systems.
