ADCIN strengthens agricultural capacity and resilience in sub-Saharan Africa

Written by dmedina on . Posted in Blogs.

The Africa Dryland Crops Improvement Network (ADCIN) emphasizes capacity building as a cornerstone for sustainable development and agricultural innovation. By addressing both human and infrastructure development, ADCIN is empowering research institutions and individuals across Africa to enhance agricultural practices, strengthen food security, and improve livelihoods in dryland regions.

In 2023, ADCIN made significant strides toward these goals by investing $1 million to strengthen National Agricultural Research and Extension Systems (NARES). This initiative focused on enhancing human capacity and infrastructure, equipping researchers, students, and institutions to address the unique challenges of dryland agriculture. The funding supported 32 awardees from East and Southern Africa (ESA) and West and Central Africa (WCA), including 15 visiting scientists, 7 students, 4 group training sessions, and 6 infrastructure development projects.

In 2024, ADCIN organized multiple training sessions in Senegal, Ethiopia, Nigeria, and Kenya, targeting seed system development, business sustainability, crop production improvements, and advanced data management techniques. These capacity-building efforts promoted knowledge sharing, collaborative research, and best practices in seed systems, crop breeding, agronomy, and data analytics. Four group training sessions were held: two in Kenya and Ethiopia for the ESA region, and two in Senegal and Nigeria for the WCA region.

Strengthening Seed Companies and CBOs for Growth in Nigeria

ADCIN, in collaboration with Syngenta Foundation Nigeria, hosted a two-day capacity-building workshop for seed companies and community-based organizations (CBOs) in Kano, Nigeria, on September 4–5. Supported by partners such as CDA, IITA, ICRISAT, and NASC, the workshop aimed to enhance seed production and commercialization efforts while promoting AVISA crops like sorghum, pearl millet, groundnut, and cowpea.

The workshop attracted 30 participants, including 20 CBOs and 10 seed companies, who were trained in topics such as seed production best practices, post-harvest handling, and seed certification standards. Key outcomes included the implementation of modern innovations like e-certification and seed tracking technologies, designed to improve transparency and efficiency in the seed sector.

Participants were also introduced to the Farmers’ Hub concept, which offers smallholder farmers access to essential agricultural inputs, machinery, and market opportunities. Many participants expressed enthusiasm about using the Farmers’ Hub to expand their customer base and grow their businesses.

“The networking opportunities provided by this training have been invaluable. I’m looking forward to applying what I’ve learned and taking my business to the next level,” shared one participant.

The training is expected to have a lasting impact on seed quality and foster business growth in Nigeria. By equipping CBOs to transition into fully operational seed companies, ADCIN is advancing the sustainability of Nigeria’s seed industry. Participants are now better prepared to tackle challenges in seed production, marketing, and regulatory compliance, paving the way for a more resilient seed sector.

With the knowledge gained from the workshop, participants are now better prepared to address the challenges of seed production, marketing, and regulatory compliance, paving the way for a more resilient and robust seed industry in Nigeria. 

Promoting Crop Improvement in Senegal

From August 20-27, 2024, more than 50 breeding and crop protection technicians from nine West and Central African countries gathered in Saly, Senegal for a comprehensive training session. The training, co-funded by the AVISA project and organized by CIMMYT in collaboration with National Agricultural Research and Extension Systems (NARES) from nine West and Central African countries, including Burkina Faso, Cameroon, Chad, Ghana, Mali, Niger, Nigeria, Togo, and Senegal, aimed to improve the efficiency of cowpea, groundnut, pearl millet, and sorghum breeding operations. 

Participants gained hands-on experience in key areas such as seed trial management, electronic data collection, and genotyping. These skills are essential for improving crop varieties and making them more resilient to local conditions. 

Field trips to Bambey, Senegal allowed participants to practice techniques such as setting up and managing seed trials, leaf sampling for genotyping, and electronic data collection using tablets making research more efficient and accurate.

“This training has given me new insights into how we can improve our breeding programs and provide better seeds for our farmers. The practical sessions were particularly helpful,” said a participant.

By enhancing technicians’ skills in trial management and data collection, the training is expected to improve field data accuracy and contribute to the development of climate-resilient crop varieties, directly addressing regional food security challenges.

Enhancing Seed Producers’ Skills in Ethiopia

ADCIN held a three-day workshop in Addis Ababa, Ethiopia, from July 30 to August 1, 2024, focusing on building the capacity of the country’s seed producers. Organized in collaboration with the Ethiopian Institute of Agricultural Research (EIAR) and supported by CIMMYT, the workshop aimed to strengthen Ethiopia’s seed producers by improving their skills in key areas such as seed health management, seed business management, variety maintenance, breeder seed production, and postharvest handling. 

The training attracted 19 participants from both the public and private sectors, including seed companies, producer associations and research centers. The sessions provided critical insights into the management of seed-borne diseases such as mycotoxins and aflatoxins, which affect crops like sorghum, chickpea, beans, and finger millet. Participants learned how to incorporate seed health testing into Ethiopia’s national certification process, which will help ensure healthier seeds and increased crop productivity.

The seed business management session introduced participants to the Business Model Canvas (BMC), a framework for creating viable and demand-driven seed business models. By emphasizing sustainable practices in seed production, processing, and marketing, the training equipped participants with the tools they need to grow their seed businesses and contribute to Ethiopia’s growing agricultural sector. 

The workshop also discussed the importance of variety maintenance and breeder seed production, focusing on the genetic integrity of improved varieties. The postharvest handling session focused on seed storage techniques and pest management, helping participants in maintaining seed quality after harvest. 

“This workshop has really opened our eyes to new business strategies and how we can ensure that our seed businesses remain profitable and sustainable,” shared a representative from a local seed company. 

Through this training, ADCIN is supporting Ethiopia’s seed producers in their efforts to improve seed quality and business sustainability, thereby contributing to the long-term growth of the seed industry. 

Equipping Breeders with Advanced Data Management Skills in Kenya

ADCIN held a training on modern biometrics, quantitative genetics and data management in Nairobi, Kenya, from 10 to 14 June. This capacity-building initiative brought together 43 participants from nine Eastern and Southern African (ESA) countries, representing breeding leaders, data champions, and young breeders working on crops such as chickpea, finger millet, pearl millet, pigeonpea, and sorghum.

The training focused on data-driven decision-making in breeding programs and covered topics such as experimental design, advanced data analysis using the CGIAR Breeding Analytical Pipeline, and managing genotype x environment (GxE) interactions. Participants learned about the Breeding Management System (BMS), quality control processes, and practical applications of the CGIAR Breeding Analytical Pipeline, which enhanced their ability to analyze large data sets and improve breeding accuracy across the CGIAR-NARES network. 

A Holistic Approach to Capacity Development

These training programs are just a small part of ADCIN’s broader initiative to build capacity across Africa’s dryland regions. These efforts, which focus on critical areas such as seed production, crop improvement, business sustainability, and data management, are helping to develop resilient agricultural systems capable of withstanding the challenges of dryland agriculture. As ADCIN works to strengthen robust and sustainable seed industries, these capacity-building programs will play an important role in increasing food security and improving the livelihoods of communities in Africa’s drylands. 

CropSustaiN BNI Wheat Mission

Written by Julian Bañuelos-Uribe on . Posted in Uncategorized.

The Novo Nordisk Foundation and CIMMYT have launched the 4-year CropSustaiN initiative to determine the global potential of wheat that is significantly better at using nitrogen, thanks to Biological Nitrification Inhibition (BNI)—and to accelerate breeding and farmer access to BNI wheat varieties.

With a budget of US$ 21 million, CropSustaiN addresses the pressing challenges of nitrogen pollution and inefficient fertilizer use, which contribute to greenhouse gas (GHG) emissions and ecological degradation. Currently, no other seed or agronomic practice-based solution matches BNI crops’ mitigation impact potential. Growing BNI crops can complement other climate mitigation measures.

The challenge

Agriculture is at the heart of both food and nutrition security and environmental sustainability. The sector contributes ca. 10-12% of global GHG emissions, including 80% of the highly potent nitrous oxide (N2O) emissions. Fertilizer use contributes to such N losses, because plants take up about 50%, the remainder being lost. Wheat is the world’s largest ‘crop’ consumer of nitrogen-based fertilizer—a relatively nitrogen-inefficient cereal—at the same time providing affordable calories to billions of resource-poor people and ca. 20% of globally consumed protein. CropSustaiN targets this nexus of productivity and planetary boundary impact by verifying and thus de-risking the needed breeding, agronomic, and social innovations.

A solution: BNI-wheat

BNI is a natural ability of certain plant species to release metabolites from their roots into the soil. They influence the nitrogen-transforming activity of nitrifying bacteria, slowing down the conversion of ammonium to nitrate in the soil. This preserves soil ammonium levels for a longer time, providing plants with a more sustained source of available nitrogen and making them more nitrogen-use efficient (nitrogen plant use efficiency). As a result, BNI helps reduce the release of N2O gas emissions and nitrate leaching to the surrounding ecosystem.

A research breakthrough in 2021, led by the Japan International Research Center of Agricultural Sciences (JIRCAS) in collaboration with CIMMYT, demonstrated that the BNI trait can be transferred from a wheat wild relative to a modern wheat variety by conventional breeding. BNI wheat can be made available to farmers worldwide.

Growing BNI wheat could reduce nitrogen fertilizer usage by 15-20%, depending on regional farming conditions, without sacrificing yield or quality.

 

Incorporating BNI into additional crops would reduce usage further. Farmers can get the same yield with less external inputs.

Other BNI-crops

CropSustaiN will work on spring and winter wheats. Rice, maize, barley, and sorghum also have BNI potential. CropSustaiN will build the knowledge base and share with scientists working on other crops and agronomic approaches.

Objectives and outcomes

This high risk, high reward mission aims to:

  • Verify the global, on-farm potential of BNI-wheat through field trial research and breeding.
  • Build the partnerships and pathways to meet farmer demand for BNI-wheat seeds.
  • Work with stakeholders on policy change that enables BNI crops production and markets

Success will be measured by determining nitrogen pollution reduction levels under different soil nitrogen environments and management conditions on research stations, documenting crop performance and safety, breeding for BNI spring and winter wheats for a wide range of geographies, and gauging farmer needs, interest, and future demand.

A collaborative effort

CIMMYT is the lead implementer of Novo Nordisk Foundation’s mission funding. CropSustaiN’s interdisciplinary, intersectoral, systems approach relies on building partnerships and knowledge-sharing within and outside this research initiative. 45+ partners are engaged in CropSustaiN.

The potential GHG emissions reduction from deploying BNI-wheat is estimated to be 0.016-0.19 gigatonnes of CO2-equivalent emissions per year, reducing 0.4-6% of total global N2O emissions annually, plus a lowering of nitrate pollution.

Impact on climate change mitigation and Nationally Determined Contributions (NDCs)

The assumption is that BNI wheat is grown in all major wheat-growing areas and that farmers will practice a behavioral shift towards lower fertilizer use and higher fertilizer use efficiency. That could lead to ca. a reduction of 17 megatons per year globally. This can help nations achieve their NDCs under the Paris Agreement.

International public goods, governance, and management

CIMMYT and the Foundation are committed to open access and the dissemination of seeds, research data, and results as international public goods. The governance and management model reinforces a commitment to equitable global access to CropSustaiN outputs, emphasized in partnership agreements and management of intellectual property.

Invitation to join the mission

The CropSustaiN initiative is a bold step towards agricultural transformation. You are invited to become a partner. You can contribute to the mission with advice, by sharing methods, research data and results, or becoming a co-founder.

New heat-tolerant wheat varieties prove fruitful for Ethiopia’s irrigated lowlands

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

Ethiopia is the largest wheat producer in Africa, accounting for around 65% of the total wheat production in sub-Saharan Africa. Despite the old tradition of rainfed wheat cultivation in the highlands, irrigated production in the dry, hot lowlands is a recent practice in the country.

In the irrigated lowlands of Afar and Oromia, situated along the Awash River Basin, CIMMYT and the Ethiopian Institute of Agricultural Research (EIAR) have been supporting small scale farming households to improve yields since 2021. The Adaptation, Demonstration and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) project supports research centers to identify new technologies suitable for target planting areas through adaptation and development, which are then released to farmers. Funded by Germany’s Federal Ministry for Economic Development (BMZ) and Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GMBH, EIAR leads on implementation while CIMMYT provides technical support and coordination.

So far, several bread and durum wheat varieties and agronomic practices have been recommended for target areas through adaptation and demonstration. The seeds of adapted varieties have been multiplied and distributed to small scale farmers in a cluster approach on seed loan basis.

Cross-continent collaboration

The Werer Agricultural Research Center (WRC) run by EIAR has released two wheat varieties: one bread wheat line (EBW192905) and one durum wheat line (423613), both suitable for agroecology between 300-1700 meters above sea level.

Both varieties were selected from the CIMMYT wheat breeding program at its headquarters in Mexico. The new bread wheat variety exceeded the standard checks by 17% (Gaámabo and Kingbird) and 28% (Mangudo and Werer). 

The lines were trialed through multi-location testing in Afar and Oromia, with both lines displaying tolerance to biotic and abiotic stresses. Accelerated seed multiplication of these varieties is in progress using main and off seasons.

“These new varieties will diversify the number of adapted wheat varieties in the lowlands and increase yields under irrigation” said Geremew Awas, a CIMMYT research officer working for the ADAPT project in Ethiopia. Hailu Mengistu, EIAR wheat breeder at WRC, also indicated the need for fast seed delivery of climate resilient wheat varieties on farmers’ hands to realize genetic gain and increase income and food security of the households.

These new varieties will be provided with a local name by breeders to make it easy for farmers and other growers to identify them and will be introduced to farmers through demonstrations and field days. Eligible seed growers who are interested in producing and marketing the basic and certified seeds of these varieties can access early generation seeds from the WRC.

Discovering the potential of multispectral UAV and satellite sensors in detecting wheat rust in Ethiopia

Written by Julian Bañuelos-Uribe on . Posted in Publications.

Latest advances in sensor technology and data processing allow early detection, mapping and monitoring of crop infestation, helping prevent large-scale outbreaks.

A recent study published in Nature Scientific Reports, assesses the capability of very high-resolution satellite (VHRS) imagery and high-resolution unmanned aerial vehicles (UAVs) imagery for high-throughput phenotyping and detecting impacts of wheat rusts in earlier crop growth stages. UAVs and VHRS offer high potential for nonintrusive, extensive, rapid and flexible measurements of plant biophysical properties at very high spatial and temporal scales.

The study—led by CIMMYT in partnership with the Ethiopian Institute of Agricultural Research (EIAR) and Lincoln Agritech Ltd from New Zealand—establishes that these advanced sensor technologies are emerging as gamechangers in crop health management. They save time, complement traditional disease scoring methods and field surveys, and are cost-effective.

Further, the study establishes that multispectral VHRS sensors can pave the way for the upscaling of disease severity assessment from plot to regional scales at early growth stages.

Wheat rust is a global challenge

Globally, crop infections are an increasing threat to crop production and food security. Increased cross-border trade and travel, coupled with a changing climate are resulting in increased frequency and severity of crop disease outbreaks. Of all the diseases that affect wheat, wheat rusts are among the most damaging, capable of causing epidemics on a vast scale with significant economic and production losses. As of date, global losses from wheat rusts equate to 15 million tonnes per year (USD $2.9 billion). In Ethiopia, a major stripe/yellow-rust epidemic in 2010 affected an estimated 600,000 hectares, resulting in production losses of 15–20% and causing economic losses of USD $250 million. Similarly, a stem/black rust (SR) epidemic from 2013-2014 infected approximately 40,000 hectares. SR, which can cause 100% crop loss within weeks, is re-emerging as a major concern to wheat production.

Early detection, monitoring and timely intervention is key

Rapid early-season detection, monitoring and timely control of wheat rusts in susceptible varieties are critical to avoid large-scale outbreaks, especially in countries where fungicides are scarcely available or too costly for smallholders. UAV-based high-throughput phenotyping (HTP) has been recently investigated to support wheat improvement breeding, in particular, to assess plant growth development, canopy architecture, physiology, reaction to abiotic stress, crop disease and insect pest response, and wheat yield.

Figure 1

Spectral and thermal measurements at the plant and canopy levels allow for monitoring the interactions between plant germplasm and environmental (abiotic and biotic) factors. The current study identifies several spectral features from UAV and VHRS multispectral imagery that have strong assessment power for the detection of combined wheat rust diseases at early crop growth stages.

During a randomized trial conducted in Ethiopia, six bread wheat varieties with differing rust resistance were monitored using UAV and VHRS. In total, 18 spectral features were tested to assess stem and yellow rust disease progression and associated yield loss. Spectral properties of the wheat canopy (e.g., pigmentation, moisture, and biomass) are altered under rust disease stress. Using multispectral images and derived vegetation indices, it is possible to determine crop susceptibility to diseases and consequently can be used for detection and monitoring of wheat rusts.

Figure 2

Recent research on wheat, maize and dry bean demonstrated strong and significant correlations between vegetation indices extracted from UAV and VHRS imagery, confirming the feasibility of VHRS-HTP targeting biomass and yield; however, such satellite applications for plant breeding programs are still scarce.

Looking ahead to upscaling

This study provides valuable insight into the upscaling capability of multispectral sensors for disease detection from UAV imagery at 5 cm per pixel to pan-sharpened satellite imagery at 50 cm per pixel, demonstrating a first step towards upscaling disease detection from plot to regional scales. Further work will expand and improve current methodology to examine the VHRS detection capability towards machine and deep learning techniques (e.g., convolutional neural network) to allow for continuous monitoring systems, focusing on both single and mixed rust diseases under different treatments (e.g., variable fungicide rates, irrigation rates).

The early detection of diseases through spectral analysis and the integration of machine learning algorithms offers invaluable tools to mitigate the spread of infections and implement prompt disease management strategies.

Wheat pathogen surveillance system set to expand through new investment

Written by Julian Bañuelos-Uribe on . Posted in Press releases.

One of the world’s largest crop pathogen surveillance systems is set to expand its analytic and knowledge systems capacity to protect wheat productivity in food vulnerable areas of East Africa and South Asia.

Researchers announced the Wheat Disease Early Warning Advisory System (Wheat DEWAS), funded through a $7.3 million grant from the Bill & Melinda Gates Foundation and the United Kingdom’s Foreign, Commonwealth & Development Office, to enhance crop resilience to wheat diseases.

The project is led by David Hodson, principal scientist at CIMMYT, and Maricelis Acevedo, research professor of global development and plant pathology at Cornell University’s College of Agriculture and Life Sciences. This initiative brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Wheat DEWAS aims to be an open and scalable system capable of tracking important pathogen strains. The system builds on existing capabilities developed by the research team to provide near-real-time model-based risk forecasts and resulting in accurate, timely and actionable advice to farmers. As plant pathogens continue to evolve and threaten global food production, the system strengthens the capacity of countries to respond in a proactive manner to transboundary wheat diseases.

The system focuses on the two major fungal pathogens of wheat known as rust and blast diseases. Rust diseases, named for a rust-like appearance on infected plants, are hyper-variable and can significantly reduce crop yields when they attack. The fungus releases trillions of spores that can ride wind currents across national borders and continents and spread devastating epidemics quickly over vast areas.

Wheat blast, caused by the fungus Magnaporte oryzae Tritici, is an increasing threat to wheat production, following detection in both Bangladesh and Zambia. The fungus spreads over short distances and through the planting of infected seeds. Grains of infected plants shrivel within a week of first symptoms, providing little time for farmers to take preventative actions. Most wheat grown in the world has limited resistance to wheat blast.

“New wheat pathogen variants are constantly evolving and are spreading rapidly on a global scale,” said Hodson, principal investigator for Wheat DEWAS. “Complete crop losses in some of the most food vulnerable areas of the world are possible under favorable epidemiological conditions. Vigilance coupled with pathogen-informed breeding strategies are essential to prevent wheat disease epidemics. Improved monitoring, early warning and advisory approaches are an important component for safeguarding food supplies.”

Previous long-term investments in rust pathogen surveillance, modelling, and diagnostics built one of the largest operational global surveillance and monitoring system for any crop disease. The research permitted the development of functioning prototypes of advanced early warning advisory systems (EWAS) in East Africa and South Asia. Wheat DEWAS seeks to improve on that foundation to build a scalable, integrated, and sustainable solution that can provide improved advanced timely warning of vulnerability to emerging and migrating wheat diseases.

“The impact of these diseases is greatest on small-scale producers, negatively affecting livelihoods, income, and food security,” Acevedo said. “Ultimately, with this project we aim to maximize opportunities for smallholder farmers to benefit from hyper-local analytic and knowledge systems to protect wheat productivity.”

The system has already proven successful, contributing to prevention of a potential rust outbreak in Ethiopia in 2021. At that time, the early warning and global monitoring detected a new yellow rust strain with high epidemic potential. Risk mapping and real-time early forecasting identified the risk and allowed a timely and effective response by farmers and officials. That growing season ended up being a production record-breaker for Ethiopian wheat farmers.

While wheat is the major focus of the system, pathogens with similar biology and dispersal modes exist for all major crops. Discoveries made in the wheat system could provide essential infrastructure, methods for data collection and analysis to aid interventions that will be relevant to other crops.

Wheat Disease Early Warning Advisory System (DEWAS)

Written by Sarah McLaughlin on . Posted in Uncategorized.

The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the world’s largest and most advanced crop pathogen surveillance systems. With Wheat DEWAS, researchers are building an open and scalable system capable of preventing disease outbreaks from novel pathogen strains that threaten wheat productivity in food vulnerable areas of East Africa and South Asia.

The system builds from capabilities developed previously by multi-institutional research teams funded through long-term investments in rust pathogen surveillance, modelling, and diagnostics. Once fully operationalized, the project aims to provide near-real-time, model-based risk forecasts for governments. The result: accurate, timely and actionable advice for farmers to respond proactively to migrating wheat diseases.

The Challenge

Farmers growing wheat face pathogen pressures from a range of sources. Two of the most damaging are the fungal diseases known as rust and blast. Rust is a chronic issue for farmers in all parts of the world. A study in 2015 estimated that the three rust diseases — stem, stripe and leaf — destroyed more than 15 million tons of wheat at a cost of nearly $3 billion worldwide. Wheat blast is an increasing threat to wheat production and has been detected in both Bangladesh and Zambia. Each of these diseases can destroy entire harvests without warning, wiping out critical income and food security for resource-poor farmers in vulnerable areas.

The Response

Weather forecasts and early-warning alerts are modern technologies that people rely on for actionable information in the case of severe weather. Now imagine a system that lets farmers know in advance when dangerous conditions will threaten their crop in the field. Wheat DEWAS aims to do just that through a scalable, integrated, and sustainable global surveillance and monitoring system for wheat.

Wheat DEWAS brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Scaling impact of dryland crops research through regional crop improvement networks

Written by Susan Otieno on . Posted in News.

The formation of regional crop improvement networks took center stage at a meeting held in January 2023 in Accra, Ghana. The meeting convened more than 200 scientists and stakeholders in dryland crops value chains from 28 countries from Africa and across the globe to co-design a network approach.

The meeting followed a series of consultative visits and discussions between three CGIAR research centers — the International Maize and Wheat Improvement Center (CIMMYT), Alliance of Bioversity International and CIAT, and the International Institute of Tropical Agriculture (IITA) — African National Agricultural Research Institutes (NARIs), and other common-visioned partners during 2021 and 2022. These earlier discussions gathered insights, brainstormed, and co-designed approaches to empower national programs to deliver impact through their crop improvement programs.

“The idea is to add value to the existing capacities in National Agricultural Research and Extension Services, through networks where the partners agree on the goals and resources needed to achieve desired outcomes. So, it’s really a collaborative model,” said Harish Gandhi, breeding lead for dryland legumes and cereals at CIMMYT. He added that the teams have been learning from and aiming to add value to existing models such as the Pan-Africa Bean Research Alliance (PABRA), USAID Innovation Labs, and Innovation and plant breeding in West Africa (IAVAO).

Paradigm shift for African National Agricultural Research Institutes

Making the opening remarks, Ghana Council for Scientific and Industrial Research (CSIR) Director General, Paul Bosu said that at the very least, African countries should aim to feed themselves and transition from net importers to net exporters of food. “Dryland legumes and cereals, especially millet and sorghum, are very well adapted to the continent and offer great opportunity towards achieving food security”, said Bosu. He applauded the Bill & Melinda Gates Foundation and other partners for investing in research on these crops.

Representing West and Central African Council for Agricultural Research and Development (CORAF), Ousmane Ndoye noted that research in dryland legumes and cereals is a valid and needed action amidst the COVID-19 pandemic and civil unrest in different parts of the world. He added that the first and crucial step to increasing food production especially in sub-Saharan Africa is the availability of sufficient quantities of seed.

Director General of Uganda’s National Agriculture Research Organization (NARO), Ambrose Agona observed that a paradigm shift should occur for desired transformation in agriculture. He noted that African governments ought to commit adequate budgets to agriculture and that seed funding should serve to complement and amplify existing national budgets for sustainability.

He commended efforts to consult NARIs in Africa and noted that the quality of ideas exchanged at the meeting strengthen the work. “The NARIs feel happier when they are consulted from the very beginning and contribute to joint planning unlike in some cases where the NARIs in Africa are only called upon to make budgets and are excluded from co-designing projects”, said Agona.

Challenge to deliver effectively

During his remarks at the meeting, CIMMYT Director General Bram Govaerts noted that the focus legume and cereal crops are key to transforming and driving diversification of food systems in Africa. “It is therefore an honor and a privilege to work together with partners to improve cereal and legume systems. We will put forward our experience in breeding and commit to innovative systems approaches towards achieving impact and leverage what we are already good at, to become even better,” said Govaerts.

Referencing his visit with the United States Special Envoy for Global Food Security Cary Fowler to Southern Africa in January 2023, Govaerts narrated witnessing firsthand a food, energy and fertilizer crisis impacting Zambian and Malawian farmers. He challenged the meeting participants to envision the future impact they would like to see their breeding programs have as they design and strategize at the meeting. He pointed out that farmers are more interested in the qualities and characteristics of varieties released than the institutions responsible for the release.

CIMMYT Global Genetic Resources Director and Deputy Director General, Breeding and Genetics, Kevin Pixley also underscored the need to generate more impact through adoption of improved varieties in Africa. Pixley noted that on average, fewer than 30 percent of farmers are using improved varieties of sorghum, millet, and groundnut across the countries with ongoing work.

The meeting heard One CGIAR’s commitment to deliver resilient, nutritious and market preferred varieties as part of its Genetic Innovation Action Area, alongside improving systems and processes for sustainability from CGIAR Senior Director Plant Breeding and Pre-Breeding, John Derera. Speaking in the capacity of IITA’s Breeding Lead, Derera noted the progress made in IITA cowpea breeding program, including its modernization, owing to strong partnerships, cross learning and germplasm exchange between institutions.

PABRA Director & Leader of the Bean Programme at the Alliance of Bioversity International and CIAT, Jean-Claude Rubyogo, pointed out that despite remarkable achievements, such as those witnessed in the bean research, more effort is needed to tackle the challenges of climate change and also increase understanding of consumers traits.

Commenting on innovative pathways to improve adoption of improved varieties, the Director General of the Institute of Agricultural Research (IAR) in Zaria, Nigeria, Mohammad Ishiyaku observed the tendency for some seed companies to continue selling specific seed varieties for years, even when the productivity of the variety is low. He noted the seed companies always claimed consumer preferences concluding then that amidst investor demands, breeders ought to keenly investigate the expectations of consumers and famers to arrive at the best parameters for breeding choices.

International Year of Millets, 2023

The gathering commemorated the International Year of Millets by listening to a keynote address on “Millets for food and nutritional security and mitigating climate change – #IYM2023” by Lake Chad Research Institute, Nigeria, Research Director, Zakari Turaki. The keynote was followed by statements on the importance of millets for various countries and wider Africa from: Sanogo Moussa Daouda, representing Director General of Mali’s Institut d’Économie Rurale (IER); Ibrahima Sarr, Director of Senegal’s Institut Sénégalais de Recherches Agricoles’s Centre National de Recherches Agronomiques; Hamidou Traore, Director of Burkina Faso’s Institut de L’Environnement et de Recherches Agricoles; and Ambrose Agona, Director General of NARO, Uganda.

High-level statements on approaches to gender integration in agricultural research and development were delivered by Scovia Adikini, NARO millet breeder, Geoffrey Mkamillo, Director General of Tanzania’s Agricultural Research Institute (TARI), Francis Kusi of Ghana’s Savanna Agricultural Research Institute (SARI), and Aliou Faye, Director of Senegal’s Regional Center of Excellence on Dry Cereals and Associated Crops (CERAAS).

AVISA Achievements

Finally, this meeting marked the transition from the recently ended Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project to align with One CGIAR initiatives under the Genetic Innovation Action Area, with specific focus on dryland crops.

Solomon Gyan Ansah, the Director of Crop Services at the Ministry of Food and Agriculture, Ghana, acknowledged the success of AVISA Project and commended the forum’s efforts to build on the gains made by the project in developing the new approach.

“By the end of 2022, AVISA project partners had reached 4.8 million farmers with 30,600 metric tons of seed of improved legume and cereal varieties, covering almost one million hectares of land”, revealed Chris Ojiewo, Strategic Partnerships and Seeds Systems Lead. Other achievements supported by the AVISA Project include upgrading of NARES facilities and building capacities of researchers through short- and long-term trainings.

The meeting was hosted by Ghana Council for Scientific and Industrial Research (CSIR) and Ghana’s Savannah Agricultural Research Institute (SARI), and was organized by CIMMYT, in partnership with IITA and the Alliance of Bioversity and CIAT (ABC).

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.”

CIMMYT leads innovation sprint to deliver results to farmers rapidly

Written by Sarah McLaughlin on . Posted in Features.

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

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

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

Nitrogen in China

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

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

Triple wins in Kenya

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

Agricultural innovations in Pakistan

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

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

Policies and partnerships for innovations in soil fertility management in Nepal

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

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

Public-private partnerships accelerate access to innovations in South Asia

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

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

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

Sustainable agriculture in Zambia

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

Shared priorities and plans for partnership

Written by Enawgaw Sisay on . Posted in News.

In early September 2022, the International Maize and Wheat Improvement Center (CIMMYT) Director General Bram Govaerts made a brief visit to Ethiopia — his first since taking on the role in 2021. Over two days in Addis Ababa he met with a number of government representatives, donors and partners, including the Agricultural Transformation Institute (ATI), the Ethiopian Institute for Agricultural Research (EIAR), Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GmbH, and The Development Fund.

Discussions centered around South-South cooperation and how CIMMYT’s strategic priority to transform agrifood systems can support efforts to improve the livelihoods of resource poor farmers in Ethiopia and national food security. Through longstanding collaboration with local partners, CIMMYT has continued to support the country through maize and wheat germplasm supply, joint technology generation and demonstrations at scale, but the visit provided an opportunity to identify shared priorities and key areas for partnership.

Supporting a plan for self-sufficiency

In a meeting with representatives from the ATI and EIAR, the CIMMYT delegation were briefed on the elements of the Government of Ethiopia’s ten-year development plan and its targets to achieve food self-sufficiency by 2030, with commercialization, advocacy on land ownership, and financial sector reform emerging as key areas of focus.

In terms of policy change, explained ATI Director General Mandefro Nigussie, there are ten core agendas that the government has set and plans to implement in the coming years. These include land governance and advisory; public-private partnership; marketing and infrastructure; and digital agriculture. The continued need for capacity building emerged as a key concern, as high staff turnover has meant many of those trained by CIMMYT previously had now left their posts.

Govaerts thanked ATI and EIAR for their collaboration so far, noting that this would surely continue as CIMMYT planned to double engagement, collaboration, production and partnerships in the coming years. Addressing the concerns raised around capacity building, particularly the training of experts, he explained that training opportunities had been limited in the last two years because of the COVID-19 pandemic and budget constraints, but capacity building for research and extension was included in the list of future action points, including a ministerial visit to CIMMYT offices in either Mexico or India.

The discussions were productive, and participants reached agreement on several other points, including collaboration on the establishment of a One Stop Shop by ATI; supporting EIAR’s data warehouse development that will provide farmers with access to an agronomy advisory services hotline; and supporting the breading of wheat for heat tolerance and Ethiopia’s irrigated wheat initiative.

Strengthening collaboration

Govaerts later met with several representatives from The Development Fund, including Country Director for Ethiopia Ulf Flink, to discuss opportunities for strengthening partnerships for greater impact. The Development Fund’s Ethiopian portfolio has evolved over four decades from supporting relief work by one Tigrayan organization to supporting multiple projects with several organizations in Tigray and Afar, with a focus on socio-economic development to alleviate poverty, and improve food security and natural resource management in dryland areas.

While the organization has recently encountered challenges in Tigray, with several programs disrupted by instability, Flink noted that the implementation of The Development Fund’s collaborative projects with CIMMYT are progressing well and pointed out opportunities to scale-up joint operations in the region, where more than 5,000 farmers have been supported so far.

Govaerts thanked The Development Fund for the strong collaboration so far and emphasized CIMMYT’s need for continued strategic partnership in South-South collaboration that can make a difference to smallholders in the country. He also pointed to CIMMYT’s aim of doubling impact and coverage, highlighting that changes in partners’ thinking and ways of intervening could be opportunities to strengthen collaboration with The Development Fund.

Cognizant of the limitations imposed by major challenges such as funding modalities — which are shifting towards humanitarian rather than development assistance — and the increasing price of mechanization, meeting participants were able to agree on a number of action points to support future collaborative work. These include continued support to project implementation in Tigray when the security situation allows; exploring opportunities to strengthen collaborations in other countries such as Malawi; and supporting research-based advocacy at both regional and zonal levels.

Additionally, CIMMYT will share its methodology for Integrated Development and research-based humanitarian development support, and work with The Development Fund to provide improved crop varieties and grain with smallholder famers in drought- and conflict-affected areas where projects are being implemented.

Drought-tolerant maize and use of forecasting in agriculture praised by the Bill & Melinda Gates Foundation

Written by Sarah McLaughlin on . Posted in Features.

The work of maize and wheat scientists at CGIAR and the International Maize and Wheat Improvement Center (CIMMYT) has been featured in the latest Goalkeepers report from the Bill & Melinda Gates Foundation, which launches with the Global Goals Awards on September 20 and an open-to-all live-streamed event on September 21. 

In analysis of why the Ukraine crisis is heavily impacting Africa, the report’s introduction from Bill Gates delves into reasons behind reliance on crop imports. Most farmers in Africa are smallholders with small plots of land and have limited capacity to use fertilizers or have access to irrigation. This means that any shock to the food system, such as the disruption to the global supply chain caused by the Ukraine conflict, hugely impacts the yield levels, threatening food and nutritional security.

Conflict is not the only risk to food systems in Africa. Climate change is the most prominent challenge that the continent’s smallholder farmers continue to face.

Developed through support from the Bill & Melinda Gates Foundation, DroughtTego, a CIMMYT-derived hybrid maize with increased resistance to hotter, drier climates, produces an average of 66% more grain per acre in Kenya. Scaled through public-private partnerships, DroughtTego seeds can increase farmer income by providing more than enough to feed a family of six for an entire year, enabling them to invest the additional money in sending their children to school or building new homes.

CIMMYT and CGIAR scientists have also been using predictive modeling to speed up plant breeding and develop new varieties that can perform well even in drought stress-prone environments of Africa. Artificial intelligence helps in processing the genomic information of crops alongside the environmental data, such as soil samples and satellite imagery. The results create a vision of what farms will need to look like in the future, enabling scientists to determine which type of crop varieties can better succeed in specific locations.

Predictive epidemiological modeling can highlight where plant diseases, such as wheat rust, may possibly spread. An early warning system, developed by a partnership between CIMMYT, the University of Cambridge, the UK Met Office, the Ethiopian Agricultural Research Institute (EIAR), the Agricultural Transformation Institute (ATI) and the Ethiopian Ministry of Agriculture, successfully alerted farmers in Ethiopia to an outbreak of the disease so that they could take preventive measures. The resulting outcome was the country’s largest wheat harvest ever recorded, instead of a devastating rust epidemic.

A LinkedIn post from Bill Gates also emphasized CIMMYT’s research, asking which crop accounts for around 30% of calorie intake for people in sub-Saharan Africa — the answer being “maize”.

Inclusion in this report highlights the global impact of CIMMYT’s work on farmers and world food systems, which is only possible through successful partnerships with organizations like the Bill & Melinda Gates Foundation.

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.

In Ethiopia, local challenges inform national action for climate-smart agriculture

In some of Ethiopia’s most vulnerable communities, climate change is having a disastrous effect on agriculture, a critical sector to the livelihood of millions. Droughts, floods, pests, and disease outbreaks are key challenges farmers face in the age of the climate crisis. These climate-related threats have already contributed to reducing agricultural productivity and food insecurity.

In order to minimize agricultural risks from the above challenges and maximize farmers’ resilience, there is a critical need to introduce the technologies, innovations, and practices that underpin ‘climate-smart agriculture. For instance, cascading knowledge on agricultural risk management and promoting conservation agriculture may prove to be sustainable practices that address the limiting factors of food security. This, however, cannot be done in a ‘one-size-fits-all’ approach. In Ethiopia, we’ve seen how climate-smart agriculture (CSA) not only needs to be localized – so it is effective in different environments – it also needs to be inclusive, meeting the needs of women and youth in various communities.

CSA is critical to making Ethiopian farmers and their communities more resilient in the face of climate change. Awareness-raising campaigns and consultations fit an important role in engaging scientists, practitioners, and beneficiaries to understand and implement area-specific climate adaptation mechanisms through CSA-based input. A current challenge is that climate-smart interventions in Ethiopia are limited because of a lack of awareness of the necessary skill set to implement and manage those technologies properly. After all, it is wise to remember that CSA is a knowledge-intensive exercise. For instance, let us look at the Ethiopian highlands, which constitute a substantial amount of the country’s farming population. In the extreme highlands of Ethiopia – generally dubbed as Wurch or mountain zone above 3800m elevation above sea level – CSA implementation is even scarce due to climatic and socio-economic conditions. In fact, those parts of the highlands are often referred to as the “forgotten agroecology” and agricultural research institutions – both in Ethiopia and beyond – must develop and package climate-smart interventions tailored for regions that have these agroecological characteristics.

Despite some practical challenges, it is also wise to note that there are successful cases of CSA implementation and addition across the various parts of the country. This is recognized for the literature review to document CSA experiences in the country and develop a detailed ‘CSA compendium’. These experiences can promote public engagement informed and inspired by the practical experience of climate-smart interventions, both from sites that have similar agroecological characteristics – as well as different – so that farmers and communities can learn from the successes and failures of other ventures. This public engagement should be underpinned by business and financing models that work for resource-poor farmers, so they can access or invest in making their agriculture more climate-smart.

Knowing what works where will be essential to develop strategies that can facilitate targeting and scaling CSA approaches. Developing a CSA compendium, a collection of concise but detailed information on CSA practices can be an entry point to achieve this – which also requires efforts from various experts and collaboration among institutions in the country and beyond.

In line with this understanding, a recent workshop in Ethiopia brought together researchers from the Ethiopia Institute of Agricultural Research (EIAR) and the Ministry of Agriculture, the Regional Bureau of Agriculture, alongside partners from regional agricultural research institutes, Universities, and CGIAR centers.

It aimed to raise awareness among partners on the kinds of climate-smart packages of agricultural technologies and practices that are socially inclusive and responsive to the needs of young people while also being feasible from a socio-economic standpoint and ready to be expanded and delivered on a bigger scale. Key presentations were made about what CSA is and what it is not. In addition, the type and description of indicators used to identify CSA practices that are economically feasible, socially acceptable, and gender-responsive were discussed in-depth. As part of this exercise, experts identified more than 20 potential climate-smart agriculture interventions tested, validated, and implemented effectively in different parts of the country.

Some of the key presentations and discussions at the workshop revealed critical lessons for implementing CSA:

  • Climate-smart agriculture is not a set of practices that can be universally applied but rather an approach that involves different elements embedded in local contexts.
  • Climate-smart agriculture relates to actions both on farms and beyond the farm, incorporating technologies, policies, institutions, and investment.”
  • Climate-smart agriculture is also a continuous process, though we should focus on the big picture and avoid trivial debates about whether CSA is a practice, technology, or an option.
  • Due consideration should be given to gender sensitiveness and social inclusiveness as a criterion in identifying compelling innovations.
  • Better indicators should be developed in measuring how climate-smart agriculture is adopted.

The workshop was the first of a series planned to raise awareness of different approaches to climate-smart agriculture while aligning Ethiopian institutions behind common understandings of how climate-smart agriculture can be delivered at both a local and national level.

In closing this first workshop, Ermias Abate, Deputy Director-General of the Amhara Region Agricultural Research Institute, stated, “Agriculture wouldn’t move an inch forward if we continued with business as usual and hence the need to be smart to face the new realities of agriculture under climate change.”

The Accelerating Impacts of CGIAR Climate Research in Africa (AICCRA) workshop was held between December 24 and 25, 2021, in Bahir Dar, Ethiopia, and was organized jointly by:

  • The Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT)
  • CGIAR Program on Climate Change Agriculture and Food Security (CCAFS)
  • International Maize and Wheat Improvement Center (CIMMYT)
  • International Center for Agricultural Research in the Dry Areas (ICARDA) and
  • International Livestock Research Institute (ILRI)

More than machines

It’s a familiar problem in international agricultural development – a project with external funding and support has achieved impressive early results, but the money is running out, the time is growing short, and there’s not a clear plan in place to continue and extend the program’s success.

Over the past seven years, the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) established Green Innovation Centers in 13 countries in Africa and two in Asia, partnering with the International Maize and Wheat Improvement Center (CIMMYT) to support projects that introduce mechanization in a way that improves long-term food security and prompts economic growth. Now, as the project enters its final two years of funding, GIZ and CIMMYT are focused on ensuring the gains produced by the Green Innovation Centers are not lost.

Like any complex challenge, there’s not just one solution to the sustainability problem – but CIMMYT is working to address a massive question around why pilots fail in agricultural development by implementing a systematic approach to scalability that recognizes the critical importance of context and puts projects on a sustainable path before the money is gone.

Training the trainers

As the Green Innovation Centers enter a crucial, final stage, a CIMMYT-led team recently completed training for seven GIZ staff from Ivory Coast, Togo, Ethiopia, and Zambia, who are now certified to facilitate CIMMYT’s Scaling Scan tool and train others to put agricultural innovations in their home countries on a solid path for growth. The training team included CIMMYT scaling advisor Lennart Woltering, CIMMYT mechanization support specialist Leon Jamann, and students from Germany’s University of Hohenheim and Weihenstephan-Triesdorf University.

The Scaling Scan is a practical tool that helps users set a defined growth ambition, analyze their readiness to scale using ten core ingredients, and identify specific areas that need attention in order to reach the scaling ambition.

The GIZ staff learned to use the Scaling Scan by applying it to early stage innovations in their home countries, ranging from commercial fodder production in the Southern Province of Zambia to seed value chains in the Oromia and Amhara regions of Ethiopia.

What will scale up in Ethiopia?

In Ethiopia, smallholding farmers producing legumes, wheat and maize struggle to increase their yield to a level that can improve food security, generate higher incomes for producers and their families, and promote economic growth and jobs in agricultural communities. To help smallholders develop sustainable solutions, GIZ senior advisor Molla Dessalegn worked with his Green Innovation Center team to brainstorm and launch a range of 20 proposed innovations – from risk mitigation and new contract structures to introduction of new technology – all with the aim of improving agricultural yields.

To date, these innovations have introduced over 200,000 Ethiopian smallholders to new knowledge and practices to improve their output. But with the project exit bearing down, Molla and his team were eager to identify which innovations held the most promise for survival and growth beyond the endpoint. So they put their pilot projects to the test using the Scaling Scan.

The scan involves an intensive, day-long seminar originally designed for in-person delivery, but remote versions have also proved successful as COVID limited global travel. The scan focuses on thorough analysis and scoring of the current state of a pilot project and its potential for growth given the realities of conditions on the ground.

Facilitators lead project managers through evaluation of the ten ingredients required for successful scaling, from finance and collaboration to technology, know-how, and public sector governance. The outcome is a clear data set assessing the scalability of the pilot and directing attention to specific areas where improvement is needed before a project can expect serious growth.

An unexpected outcome

What emerged from the scan surprised Molla. Some of the strategies he saw as most successful in the early stages, such as a contract farming program, scored poorly, whereas the scan identified deployment of mobile seed cleaners as a solution that held particular promise for scalability. These outcomes prompted the team to refocus efforts on this strategy.

About 95 percent of Ethiopian smallholders rely on informal seed systems, either saving and reusing seed or exchanging low quality seed with other farmers. Seed cleaning plays a critical role in helping farmers build a high quality, high yield seed development system. Molla and his team had already worked with smallholder cooperatives in Oromia to distribute three mobile seed cleaners, and they knew these machines were being heavily relied upon by farmers in this region.

The Scaling Scan showed them, among other things, that the successful adoption of the seed cleaners had even more potential – it was an innovation that could be sustained and even expanded by local stakeholders, including the Ministry of Agriculture.

This result prompted Molla to recommend investment in additional mobile seed cleaners – four to serve cooperatives in the Amhara region and a fifth for the West Arsi district in Oromia. These machines are now in operation and helping additional smallholders improve the quality of their seed stock. This initial expansion confirms the Scaling Scan results – and CIMMYT plans to continue supporting this growth with the purchase of another round of seed cleaners.

The Scaling Scan also identified problems with the business model for sustaining the mobile seed cleaners through cooperatives in Ethiopia, and this outcome directed the Green Innovation Centers to partner with a consultant to develop improvements in this area. In this way, one of the most important values of the scan is its ability to guide decision-making.

Scaling up the future

Seed cleaners alone won’t solve every yield problem for Ethiopian farmers, but the scan has now guided the initial implementation – and contextual adaptation – of a new form of agricultural mechanization across two regions of the country, with the promise of more to come.

And there’s more to come from the Scaling Scan as well.

Now that he’s received certification as a trainer, Molla plans to help farmers, officials, and other development workers adopt this rigorous approach to evaluating innovations that show potential. When funding for his project ends in 2024, he will be leaving 300,000 smallholders in Ethiopia with more than machines – he will be leaving them with the knowledge, experience, and practices to make the most of the technological solutions that are improving their yields today and building a more secure future for their communities.

Pilot of new wheat variety improves yield for farmers in Ethiopia

Written by Sarah McLaughlin on . Posted in Features.

“I am happy with this wheat variety and all the support from the project,” said Agere Worku, a female farmer in Ethiopia working with the International Maize and Wheat Improvement Center (CIMMYT). “It is a lot of money that I will earn as a female farmer in my life.”

Worku is just one farmer taking part in a pilot intervention as part of CIMMYT’s Adaptation, Demonstration, and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) project. Four female and four male farmers were chosen to take part from the Melke Yegna Tesfa Association, a membership group of 83 smallholder farmers, nearly half of which are female.

Participants were given Kingbird seeds, a new wheat variety, to plant in their smallholdings. The project then supported them through capacity building and advice on smart soil, water management, plant protection and agronomic packages.

“We prepared six hectares of land and sowed 1.1 tons of Kingbird seed,” said Yeshiwas Worku, chair of the Melke Yegna Tefsa Association. “There were other wheat varieties, such as Danda’a, adjacent to our experimental plot and the difference in yields was very visible. The other members of the association were eager to get Kingbird seeds, which are very different in terms of quality, yields, maturity, and disease tolerance.”

“CIMMYT is a life changer for me,” said Buzayehu Getahun, a farmer in Jeju, in the Oromia region. “I produced 3.7 tons on 0.75 hectares. Interestingly, I earned around 132,000 Ethiopian Birr (US$2,500) from this yield. I plan to build a new house for my mother in my village and will be blessed by her at her old age,” said Getahun.

The impact on female farmers

After involvement in the pilot, the female farmers produced higher yields than they had experienced before.

“I used to harvest wheat three times in the previous years and earned only 0.66 tons of wheat per 0.75 hectare using seeds of other wheat varieties,” explained Worku. “But now thanks to support from CIMMYT, the yield has increased four times than the previous years; I produced 2.4 tons per 0.75 hectares. I am very happy with the high yield and feel encouraged to reinvest in other agricultural activities.”

A second female farmer, Melishew Tedela, said, “I am happy with this seed and all the support from the project. I can be witness that the other farmers who didn’t get this variety were not happy with their low yields of wheat.”

The future of lowland wheat farming

Bekele Geleta Abeyo, wheat breeder and Ethiopia Country Representative at CIMMYT, said, “The Government of Ethiopia is emphasizing increasing irrigated wheat production and productivity in the lowlands to complement the intensification of rainfed wheat production in the highlands in order to achieve self-sufficiency by 2023 and feed the ever-growing population.”

With world wheat prices skyrocketing due to the Ukraine conflict, wheat technology generation and dissemination are key for sustainable agricultural practices.

CIMMYT is working to replace obsolete wheat varieties in Ethiopia that are susceptible to wheat rust, particularly yellow and stem rust, with disease-resistant products. Newer varieties like Kingbird are rust-resistant and therefore produce higher yields.
