In maize research, farmers’ priorities are our priorities

Written by Alison Doody on . Posted in Publications.

Figuring out what kinds of crops and crop varieties farmers want – high yielding, disease resistant, drought tolerant, early maturing, consumer-preferred, nutritious etc. – is a crucial step in developing locally adapted, farmer-friendly and market preferred varieties as part of more sustainable seed grain sectors.

While scientists aim to develop the best crop varieties with multiple traits, there are always trade-offs to be made due to the limits of genetics or competing preferences. For example, a variety may be more tolerant to drought but perform less well in consumer taste preferences such as sweet grains, or it may be higher yielding but more vulnerable to pests and diseases. Some of these trade-offs, such as vulnerability to pests or adverse climate, are not acceptable and must be overcome by crop scientists. The bundle of traits a crop variety offers is often a major consideration for farmers and can be the difference between a bumper harvest and a harvest lost to pests and diseases or extreme weather conditions.

Economists from the International Maize and Wheat Improvement Center (CIMMYT) have been working with smallholder farmers across sub-Saharan Africa to document their preferences when it comes to maize. Results from Ethiopia were recently published in the journal PLOS ONE.

In a survey with almost 1,500 participants in more than 800 households, researchers found that both male and female farmers valued drought tolerance over other traits. For many farmers in areas where high-yielding, medium-maturing hybrids were available, early maturity was not considered a priority, and sometimes even disliked, as farmers felt it made their harvests more vulnerable to theft or increased their social obligations to share the early crop with relatives and neighbors if they were the only ones harvesting an early maize crop. Farmers therefore preferred varieties which matured more in sync with other farmers.

The team also found some gender differences, with female farmers often preferring taste over other traits, while male farmers were more likely to prioritize plant architecture traits like closed tip and shorter plants that do not easily break in the wind or bend over to the ground. These differences, if confirmed by ongoing and further research, suggest that gender differences in maize variety choices may occur due to differentiated roles of men and women in the maize value chains. Any differences observed should be traced to such roles where these are distinctly and socially differentiated. In aspects where men and women’s roles are similar — for example, when women express preferences in their role as farmers as opposed to being custodians of household nutrition — they will prioritize similar aspects of maize varieties.

The results of the study show that overall, the most important traits for farmers in Ethiopia, in addition to those that improve yields, are varieties that are drought and disease tolerant, while in taste-sensitive markets with strong commercial opportunities in green maize selling, farmers may prioritize varieties that satisfy these specific consumer tastes. The findings of the study also highlight the impact of the local social environment on variety choices.

By taking farmers’ preferences on board, maize scientists can help develop more sustainable maize cropping systems which are adapted to the local environment and respond to global climatic and economic changes driven by farmers’ and consumers’ priorities.

Drought and striga tolerance come out top for Kenyan farmers

In related research from western Kenya, published in June 2022 in Frontiers in Sustainable Food Systems, results showed that farmers highly valued tolerance to drought, as well as tolerance to striga weed, low nitrogen soils and fall armyworm, in that order. CIMMYT researchers surveyed 1,400 smallholder farmers across three districts in western Kenya.

The scientists called for a more nuanced approach to seed markets, where seed prices might reflect the attributes of varieties. Doing so, they argue, would allow farmers to decide whether to pay price premiums for specific seed products thereby achieving greater market segmentation based on relative values of new traits.

“Both studies show that farmers, scientists and development experts in the maize sector are grappling with a wide array of demands,” said Paswel Marenya, CIMMYT senior scientist and first author of both studies.

“Fortunately, the maize breeding systems in CIMMYT, CGIAR and National Agricultural Research Systems (NARS) have produced a wide range of locally adapted, stress tolerant and consumer preferred varieties.”

The results of both these studies provide a framework for the kinds of traits scientists should prioritize in maize improvement programs at least in similar regions as those studied here in central Ethiopia or western Kenya. However, as Marenya noted, there is still work to do in supporting farmers to make informed choices: “The challenge is to implement rigorous market targeting strategies that sort and organize this complex landscape for farmers, thereby reducing the information load, search costs and learning times about new varieties. This will accelerate the speed of adoption and genetic gains on farmers’ fields as envisaged in this project.”

A reluctant farmer changes the fortune of his inherited land

Written by Nima Chodon on . Posted in Features.

In the sultry spring-summer heat of Bihar, India, the landscape is yellow with wheat grains ready for harvest. Here, in Nagma village farmer Ravi Ranjan attends to his fields — mostly wheat, with some pulses in the adjoining plots. The harvest this year will be a little less than anticipated, he explains, as receding monsoon rains left the soil too moist to begin sowing on time.

Ranjan’s grandfather and father were both farmers who owned sizable land. His father used to say that the land was productive but required a lot of hands, sweat, and time to sustain the yields. Agriculture was all that the family had known and depended on for decades before Ranjan’s father left the sector for the civil service. After the early demise of his grandfather in 2003, and with his father in a secure government job, it fell to Ranjan to shoulder the responsibility of managing the family farm.

As a young man, Ranjan had sometimes helped his grandfather in the fields, but now, as the owner of a hydraulic mechanical service firm working hundreds of kilometers away in Chhattisgarh, he had never imagined becoming a farmer himself. Though reluctant to begin with, Ranjan decided there was no alternative but to take on the challenge and do his best, and while initially he had little success with the new venture, slowly and steadily he began to change the fortune of his inherited land.

Today Ranjan is one of the local area’s success stories, as a progressive and influential farmer with ties to the Cereal Systems Initiative for South Asia (CSISA) project. Researchers on the CSISA team have been working with farmers like him in the region for over a decade and are proud of the ongoing collaboration. Ranjan’s fields are regularly used as CSISA trial plots to help demonstrate the success of new technologies and conservation agriculture practices that can enhance productivity and sustainability. For example, in the 2021-2022 winter cropping season — locally known as Rabi — he harvested 6.2 tons per hectare – while a separate acre plot as demonstration site was harvested publicly with officials from CSISA and the Krishi Vigyan Kendra Network (KVK), JEEViKA, and farmers from neighboring villages for improving yield sustainably.

As India celebrates Kisan Diwas (Farmer’s Day) on December 23, we speak to Ranjan about his hopes for the future and the continuity of farming in his family after he hangs his boots.

Farming has seen a sea of change since your grandfather’s time. What do you think has been the most transformative change in the years you have been involved in farming?

I think using mechanized tools and technology to ensure good cropping practices has tremendously reduced manual work. Furthermore, today with innovations and digitization in agriculture science, farming is not just recognized as a noble profession, but also an enterprising one. I am happy I came into it right when things were changing for good. I have no regrets.

Though not by choice that I came into it, I am now fully invested and devoted to farming. From being an entrepreneur to farming, it has been a transformational journey for me. I am unsure whether my daughters — I have three, the eldest turns 18 next year — will choose to be involved in agricultural farming. But I will encourage and fully support them if they choose to take it up. After all, they will inherit the land after me.

Extreme climate effects are challenging agricultural practices and output. How are you preparing to reduce the impact of these in your fields?

It is worrying to see how extreme climatic effects can be challenging for agriculture, particularly for smallholder farmers in the region. Erratic rains, drought at times, and increasing temperatures have all harmed our cereal and vegetable farms and affected yield in wheat crops significantly. The adoption of new technologies like direct seeded rice (DSR) to avoid puddled rice transplanting, early wheat sowing (EWS) to avoid terminal heat at maturity, zero tillage technology (ZTT), and better-quality seeds, are interventions introduced and supported by CSISA and other agricultural organizations from the state that has helped combat some of these climate-induced problems.

In my own fields, I have also introduced proper irrigation systems to reduce the impact of limited water availability. I hope to stay ahead of the curve and make sure I am aware of all that is possible to keep my farm productive and sustainable.

How did you begin your association with CSISA? What has been your experience of working with them to make your agriculture resilient and productive?

I was initially approached by one of their scientists working in the area. And because of my interest, they slowly began informing me of various technologies I could try. With these technologies implemented in my field, the yield and productivity improved.

Soon after expanding my agriculture output, I got 50 acres of land on lease in the village to grow more crops like pulses, along with rice and wheat. Today, CSISA has started using my fields as their demonstration plots for new technologies and best practices, and to spread awareness and bring in more farmers from neighboring villages to encourage adoption.

CSISA and others call me a progressive and innovative farmer. I am proud that many farmers and other agricultural agencies in the area have appreciated our efforts to continue making agriculture productive and sustainable.

About CSISA:

Established in 2009, the Cereal Systems Initiative for South Asia (CSISA) is a science-driven and impacts-oriented regional initiative for increasing the productivity of cereal-based cropping systems. CSISA works in Bangladesh, India, and Nepal. CSISA activities in India focus on the eastern Indo-Gangetic Plains, dominated by small farm sizes, low incomes, and comparatively low agricultural mechanization, irrigation, and productivity levels.

Sustainability of rice production in the Northwestern Indo-Gangetic Plains

Written by Sarah McLaughlin on . Posted in Publications.

Rice is a vital crop for India, contributing around 30 percent of calories consumed in the country and providing a crucial source of income from exports. However, due to climate change and conversion of land for other uses, rice growing area in India is projected to decline by 6-7 million hectares (ha) by 2050, while production must increase by 1.1% annually over the next four decades to achieve rice self-sufficiency for the country.

As there is limited opportunity to horizontal expansion of cultivable land, the predicted increase in demand must be met through increasing rice yields in regions with low yields and maintaining existing yields in high-yielding areas. This must be achieved using sustainable farming practices: currently, 90 percent of total greenhouse gas (GHG) emissions of monsoon season cropped cereals in India is caused by rice cultivation, as is 80 percent of the energy and water used in agriculture.

Scientists found that in the Northwestern Indo-Gangetic Plains (IGP) of India, yield gaps were small (ca. 2.7 t ha−1, or 20% of potential yield) mainly because of intensive production system with high input use. Using management data from 4,107 individual farmer fields, the study highlighted scope to reduce nitrogen (N) inputs without compromising yields in this intensive production system.

Findings show evidence of and methodology for the quantification of yield gaps and approaches that can improve resource-use efficiency, providing a possible alternative approach that could be reproduced elsewhere for other crops and contexts. It is recommended that future research focuses on ways to reduce other production inputs without compromising the yields in such intensive production systems.

This paper is the result of Harishankar Nayak’s PhD training in collaboration with the Indian Council of Agricultural Research (ICAR) jointly supervised by the researchers at the Indian Agricultural Research Institute (IARI) and International Maize and Wheat Improvement Center (CIMMYT).

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

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

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

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

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

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

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

Inspiring future generations of scientists

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

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

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

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

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

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

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

From November 14 to 18, the International Maize and Wheat Improvement Center (CIMMYT) and the Alliance of Bioversity International and CIAT hosted the third workshop of the Community of Practice for Latin America and the Caribbean on the use of genomic and digital tools for the conservation and use of Genetic Resources for Food and Agriculture (GRAA).

The workshop, attended by 33 participants from 14 countries, was held at CIMMYT headquarters and highlighted topics such as the analysis of genotypic data derived from the DArTseq platform and the analysis of gaps in germplasm collections.

“It was very gratifying to be able to form this Latin American network of germplasm banks together with our colleagues from the Alliance of Bioversity International and CIAT,”said Carolina Sansaloni, Wheat Germplasm Bank Curator & Genotyping Specialist. “Training and knowledge exchange among germplasm banks is essential for better conservation, exploration and utilization of genetic resources in each country.”

Some of the participants shared the following comments and feedback:

  • “Excellent initiative, it is a fundamental support for the strengthening of plant genetic resources conservation systems and the creation of international collaborative networks. Thanks to CIMMYT and the Alliance of Bioversity International and CIAT for the invitation.” Mexico’s National Institute for Forestry, Agriculture and Livestock Research (INIFAP)
  • “Excellent workshop, a very important space for the exchange of knowledge and experiences, it also allows the formation of collaborative work networks between institutions and professionals from different countries with related research.” Escuela de Ciencias Agrarias, Universidad Nacional Costa Rica
  • “This workshop has allowed me to get in contact with colleagues from Latin America and to open the possibility of working together to advance in the characterization and contribute to the conservation of the collections we manage.” Instituto Nacional de TecnologĂ­a Agropecuaria, Argentina
  • “This has been a very profitable week for me as curator of the germplasm bank in Brazil. I learnt new concepts and tools that will generate advances in my work.” Brazilian Agricultural Research Corporation (EMBRAPA)

This workshop would not have been possible without the support of the CGIAR’s Genebank Initiative, DivSeek International and Analitek-Illumina.

Participatory action research identifies solutions for improved seed storage in Bangladesh

Written by Sarah McLaughlin on . Posted in Publications.

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

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

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

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

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

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

Scoring by both men and women farmers revealed their preference for SuperGrainbags¼ hermetic storage. The study recommends actions for value chain development to increase farmers’ access to improved hermetic storage options at low cost.

Food systems that work for people and the environment

Written by Sarah McLaughlin on . Posted in News.

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

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

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

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

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

Plant breeding must adapt to climate change, finds study

Written by Sarah McLaughlin on . Posted in Publications.

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

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

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

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

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

Groundnut ESA crop improvement network sets regional and country level priorities

Written by Susan Otieno on . Posted in News.

The Accelerated Varietal Improvement and Seed Delivery of Legumes and Cereals in Africa (AVISA) project has developed draft national groundnut target product profiles in Malawi, Mozambique, Sudan, Tanzania, Uganda and Zambia.

Groundnut is grown in eastern and southern Africa, where it remains an important food and oil crop from small holder farmers.

The new findings from the project are a result of work from groundnut crop breeding and improvement teams from the National Agricultural Research and Extension Systems (NARES) representatives from the six largest groundnut producing countries in the eastern and southern Africa region.

Their important research was carried out with the support of representatives from the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA) and CGIAR.

Developing target product profiles for groundnut

For the first time, through the International Maize and Wheat Improvement Center (CIMMYT)-led AVISA program, funded by the Bill & Melinda Gates Foundation, groundnut breeding teams discussed and documented country level priorities at a meeting in Dar es Salaam, Tanzania.

Their findings were developed using a standard target product profile template recently developed by CGIAR Excellence in Breeding (EiB) in conjunction with CGIAR’s Market Intelligence Initiative. The template serves as a tool to capture market segments and develop targeted product profiles.

The groundnut breeding teams also shared information on current groundnut production metrics and trends in the six national programs. This also helped to establish a common understanding of countries’ level research priorities.

Agnes Gitonga, market strategist at CGIAR Genetic Innovations Action Area, who led the team in understanding and applying the template, explained that the quality of a target product profile (TPP) is dependent on how well market segments are defined. “To ensure target product profiles are an accurate reflection of customer needs, who include farmers, consumers, and processors,” she said.

“National groundnut teams nominated Country Product Design Teams that will meet nationally before the end of 2022 to review and update country TPPs. These multi-stakeholder teams will ensure that the needs of diverse groups are captured and that breeding efforts are accurately focused.”.

Harish Gandhi, Breeding Lead, Dryland Legumes and Cereals (DLC) at CIMMYT, further explained that a bottom-up approach for defining country and regional priorities was used, where each country defined market segments and target product profile based on the use of the produce and growing conditions of farmers. This strategy involved each country defining its market segments and TPP, which was based on the use of the produce and growing conditions of farmers.

Building on the draft national target product profiles that were defined at the meeting, participants went on to prioritize traits such as diseases, nutrition and stress tolerance. These factors can be critical at regional level and important in identifying potential locations for conducting phenotyping. The phenotyping locations are distributed based on capacity of stations in different countries to screen for traits, such as late leaf spot disease screening in Msekera in Zambia, which is a known hotspot for the disease.

“We had a good opportunity to consider grower needs as well as consumer needs in each country for purposes of defining the relevant groundnuts market segments. I believe this will have a positive impact on future work in groundnuts in the East and Southern Africa region,” reflected Gitonga.

The collaboration of the teams involved was a key factor for the project’s success so far and will be crucial in working towards its goals in the future.

“Involving different stakeholders in designing target product profile was an effective way of enabling transformation of individual preferences (area of interest) to collective preferences (targeted product) with consumer needs and markets in mind,” said Happy Daudi, Groundnut Breeding lead at the Tanzania Agricultural Research Institute (TARI).

Strengthening groundnut breeding programs in east and southern Africa

The project’s first meeting will provide an important foundation for future research, which will use the new findings as a blueprint.

Biswanath Das, Plant Breeder, Groundnut for East and Southern Africa region and NARES Coordinator and Programming lead for EiB said, “Defining national TPPs, identifying regionally important traits and mapping a testing network are fundamental building blocks of a modern breeding program.”

At the meeting, a schedule was laid out for peer-to-peer assessments of breeding programs within the regional network to take stock of current efforts and gaps. This step helps to develop customized capacity development plans for each network partner.

“Through targeted and demand led capacity development, the East and Southern Africa groundnut crop improvement network aspires to strengthen the role of each network member in collaborative, regional breeding efforts,” Das said.

The meeting laid the ground for coordinated regional groundnut breeding and took steps towards formalizing a regional NARES-CGIAR-SME groundnut crop improvement network. By building on excellent connections that already exist among national groundnut breeding teams. Das underscored that the move will strengthen alignment of NARES, CGIAR and regional research efforts around a common vision of success.

In addition, David Okello who leads groundnut research at National Agriculture Research Organization (NARO) Uganda, noted that the meeting provided a good opportunity for consolidating the existing network. He also looked forward to welcoming more groundnut improvement programs in the region on board.

CIMMYT at COP27

COP27, the UN Climate Change Conference for 2022, took place this year in Sharm El-Sheikh, Egypt, between November 6-18. Scientists and researchers from the International Maize and Wheat Improvement Center (CIMMYT) represented the organization at a wide range of events, covering gender, genebanks, soil health, and digital innovations.

Gender and food security

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

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

The role of CGIAR genebanks in a climate crisis

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

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

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

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

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

Addressing soil fertility management

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

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

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

Digital solutions for sustainable systems

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

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

Partnership approach to maize development praised in new study

Written by Sarah McLaughlin on . Posted in Publications.

Using data from 1995-2015, an empirical study from the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA), led by Vijesh Krishna, CIMMYT Lead Adoption – Impact Economist, has estimated the economic benefits of new varieties in 18 major maize-producing countries in sub-Saharan Africa.

Kevin Pixley, Deputy Director General for Research (Breeding and Genetics), a.i., and Director of the Genetic Resources Program, said, “This was not easy due to the challenges of gathering and analyzing complex data, but it’s a very important milestone for CIMMYT. Peer review in a highly respected journal is a gold standard that gives external critique and endorsement to the impact assessment methods used and estimates reported for CIMMYT and IITA’s work with partners in Africa.”

Around 60 percent of the 1,345 maize varieties released in this twenty-year period had a known CGIAR parentage.

Approximately 34 percent of the total maize area in 2015 was cultivated with CGIAR-related maize varieties from 1995 onwards, equivalent to 9.5 million hectares (ha); 13 percent of the maize area was under CGIAR-related varieties released before 1995.

The new maize varieties hold an economic benefit for the region, with an estimated value of US $1.1-1.6 billion in 2015 equally attributed to CGIAR, public-sector national research and extension programs, and private sector partners. With maximum annual investment in CGIAR maize breeding sitting at US $30 million, the estimated benefit-cost ratio for investment was between 12:1-17:1, depending on the underlying assumptions.

“This paper is a valuable contribution to literature on impact assessment, highlighting the real challenges and approaches to quantify impact of work that is a collaboration among many,” continued Pixley. “Both the methodologies and impact estimates will be valuable to researchers and funders of plant breeding programs.”
