The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the worldâs 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 â stem, stripe and leaf â 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.
Together, the researchers are focused on six interlinked work packages:Â

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 â the International Maize and Wheat Improvement Center (CIMMYT), Alliance of Bioversity International and CIAT, and the International Institute of Tropical Agriculture (IITA) â 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.
âThe 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, itâs really a collaborative model,â 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. âDryland legumes and cereals, especially millet and sorghum, are very well adapted to the continent and offer great opportunity towards achieving food securityâ, 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 Ugandaâs 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. âThe 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 projectsâ, 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. âIt 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,â 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 CGIARâs 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 IITAâs 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.

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 Tanzaniaâs Agricultural Research Institute (TARI), Francis Kusi of Ghanaâs Savanna Agricultural Research Institute (SARI), and Aliou Faye, Director of Senegalâs 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 forumâs efforts to build on the gains made by the project in developing the new approach.
âBy 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 landâ, 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 Ghanaâs Savannah Agricultural Research Institute (SARI), and was organized by CIMMYT, in partnership with IITA and the Alliance of Bioversity and CIAT (ABC).
To mark International Womenâs Day 2023, Nele Verhulst, cropping systems agronomist at the International Maize and Wheat Improvement Center (CIMMYT), shares progress from the Women in Crop Science group and how their work tries to contribute to gender equality in agriculture and science.
Growing up in the nineties in Belgium, I was interested in feminism, but I also assumed that the fight for equal rights for women and men had been fought and won. Studying bioscience engineering in the 2000s, more than half of the students were women, so this demonstrated to me that we were all set (although the large majority of professors were men, it seemed to be just a matter of time for that to be resolved). I have now been working in Latin America as an agronomist and researcher for more than 15 years and have come to realize that there is still a lot of work to do to achieve equal opportunities for female farmers, farm advisors, scientists, and other professionals in agriculture.
At CIMMYT, between 20 and 25 percent of staff in the science career track â careers involving field, lab, data, and socioeconomic work â are female. Because of that, Alison Bentley and I started a group of women in crop science at CIMMYT about one year ago on the International Day of Women and Girls in Science in 2022. In our first meeting, we aimed to connect, discussed how to build a network (we did not even have a list of all women in science at CIMMYT, so it was hard to know who to invite), and decided whether we wanted to commit to additional actions to achieve a more inclusive environment at CIMMYT.
Since that first meeting, we have organized coffee mornings and other events, and have split into smaller working groups to draft action plans on ten topics: gender in the workplace strategy development, advancement for locally recruited staff, mentorship, recruitment processes, microaggressions, harassment policies, work-life balance, family friendly work environment, raising external awareness about women in agriculture, and ensuring internal visibility.
I have enjoyed being able to make some first small changes â who knew sanitary facilities would turn out to be a recurring topic! â but most of all I have loved the opportunities over the past year to connect with women with a shared passion for crop science in all its aspects. That passion and the opportunities it creates to improve the lives of farmers and rural communities is the most important thing we are celebrating today.

Decisions on how to invest scarce resources in CGIAR-NARES genetic innovation systems have been predominantly supply-driven and therefore potentially out-of-sync with the demands of smallholders, consumers and agro-industry. The turnover of improved crop varieties developed by CGIAR and its NARES partners (National Agricultural Research and Extension Services) has been slow. Small-scale seed businesses lack incentives to actively promote new varieties given weak demand. Little is known about the drivers of varietal replacement and product substitution, and the role of downstream market actors such as traders, processors and consumers in this process.âŻÂ
There is a clear need for demand- and data-driven processes to guide genetic innovation systems, but efforts to advance this remain incomplete and fragmented within CGIAR. Current product profile design is strongly biased towards agronomic and stress-tolerance traits, with little systematic identification and integration of traits that contribute to wider social impact.Â
This Initiative aims to maximize CGIAR and partnersâ returns on investment in breeding, seed systems and other Initiatives based on reliable and timely market intelligence that enables stronger demand orientation and strengthens co-ownership and co-implementation by CGIAR and partners.
This objective will be achieved through:
Gathering market intelligence by collecting data to map global and regional challenges across CGIARâs five impact areas, translating them into regional market segments and priorities for genetic innovation by identifying drivers of demand as well as variation by gender, age and social group.
Designing new-generation, gender-intentional target product profiles for each market segment using market intelligence.Â
Generating behavioral intelligence based on what drives farmers, consumers and private-sector decisions to adopt new varieties and supporting other Initiatives in identifying cost-effective inclusive strategies for accelerating varietal uptake.Â
Developing pipeline investment cases by estimating the potential impact and return on investment across CGIARâs five impact areas of the portfolio of breeding pipelines serving the market segments and developing recommendations for the portfolio optimization and prioritization.Â
Developing institutional scaling and monitoring, evaluation, learning and impact assessment (MELIA) by establishing a collaboration hub across Genetic Innovation Initiatives and partners to develop scaling mechanisms for the adoption of institutional standards and processes in market segmentation and gender-intentional product profile design, and to conduct rigorous MELIA of the portfolio.Â
Engagement
This Initiative has a global and regional focus, with countries being prioritized as a result of the Initiativeâs work.Â
Outcomes
Proposed 3-year outcomes include:
At least three transdisciplinary teams across CGIAR and partners in prioritized regions are empowered in co-implementation of market and behavioral intelligence and co-design of product profiles.Â
At least 10 CGIAR partners in prioritized regions adopt institutional standards and processes for market segmentation and product profile design, sharing of market and behavioral intelligence and monitoring of outcomes.Â
At least five seed suppliers, food companies and NGOs in prioritized regions use market and behavioral intelligence from the Initiative in strategic decision-making.Â
At least three research leaders and investors make investment decisions using pipeline investment cases and the Initiativeâs investor dashboard and the increased availability of information and transparent, holistic analyses of high-impact opportunities attract increased investments in underinvested and new-opportunity market segments.

What is ‘Market Intelligence’?
Strategies for breeding and seed systems to deliver greater impact will benefit from reliable and comparable evidence on the needs and requirements of farmers, processors and consumers. This includes anticipating how farmers may respond to emerging threats and opportunities in light of seed-sector and product-market evolution and the changing environment. Experts generally agree that âdemand-led breedingâ will be essential to achieve more impact from investments in crop breeding. But the continued interest in a demand-led approach to the design of varieties and the prioritization of breeding pipelines requires reliable, comparable and timely market intelligence. It also requires new mechanisms for how market intelligence is collected, shared and discussed with those engaged in the design and funding of breeding pipelines and seed systems.
Over the past 25 years, social science researchers from CGIAR, NARES and universities have generated important insights on the traits and varieties farmers prefer. These farmer preferences for traits and varieties have been explored through household surveys, participatory rural appraisals and participatory varietal selection. More recently, economists have employed tools such as choice experiments, experimental auctions and gamification of farmer priority traits. Overall, a large body of work has emerged, but variations in research questions, methodologies and interventions have contributed to disparate research findings and limited the opportunities for consolidation and comparative analyses.
Looking ahead, a strategic opportunity to guide more impactful investments in crop breeding and seed systems development lies in:
designing a consistent approach for generating and disseminating market intelligence
coordinating research across CGIAR and NARES to deliver timely market intelligence;
establishing processes for coordination across social science teams and among social science, crop modelers, CGIAR-NARES networks and the private sector.
The CGIAR Initiative on Market Intelligence (âMarket Intelligenceâ for brevity) represents a new effort to engage social scientists, crop breeding teams and others to work together toward the design and implementation of a demand-led breeding approach.
Within this initiative, the International Maize and Wheat Improvement Center (CIMMYT) leads Work Package 1, âMarket Intelligenceâ, which is responsible for the design of innovative methods and tools to collect market intelligence and the application of these tools across different regions and crops relevant for CGIAR breeding. The Work Package engages either other CGIAR centers and external partners, such as CIRAD and the World Vegetable Center. An early, but critical, challenge facing the Work Package team was how to disseminate in an accessible and timely manner market intelligence to breeding teams, funders, and the private sector.
Market Intelligence Briefs
Traditionally, researchers from CGIAR, NARES and universities who have sought to inform crop breeding and seed systems programming have done so by publishing their work in reputable international peer-reviewed journals. However, the process can be slow, potentially requiring multiple revisions over years. The practical nature of market intelligence research can limit its relevance for journal editors who are looking to push theoretical debates forward. Thus, for Market Intelligence to deliver on its promise, new ways of communicating will be essential. In looking to address these limitations, work package 1 has led the design and implementation of a new publication series called Market Intelligence Briefs (MIB). Each brief is reviewed by peers, is concise (less than 4000 words), avoids technical jargon, and attempts to present conclusions in a clear and decisive manner. In 2022 the first two editions of the MIB series were published, both led by CIMMYT researchers and available online.
This brief defines several important concepts that, when taken together, form the basic framework used by the Initiative to generate comparable and useful market intelligence. Some of the definitions are inspired by previous work on demand-led breeding, while others build on work by CGIARâs Excellence in Breeding (EiB) platform. A confusing set of terms and definitions has emerged around market intelligenceâa field rooted in commercial product innovationâwith different terms and definitions for similar concepts. In the interest of clear communication and understanding among those engaged in crop breeding, seed systems and social science, this brief presents key concepts and definitions that have been discussed extensively during the initial months of implementation of Market Intelligence. We conclude the brief with reflections on the way forward for implementation.
The second brief zooms into the maize market segments in East Africa and proposes a new methodology for gathering insights from farmers about their varietal preferences to inform future market segmentation. This brief explains the conceptual and methodological underpinnings of Video-based Product Concept Testing (VPCT) and presents an application of the tool in hybrid maize. Seven new product concepts (representing potential future market segments) were identified based on discussions with breeders, seed companies and farmers, which we labelled: home use, intercropping, drought avoidance, nutritious, feed (yellow), green maize and food and fodder. These future concepts, together with the resilient benchmark product concept (the current breeding target), were evaluated through triadic comparisons with 2400 farmers in Kenya and Uganda. The results showed that concepts focused on agronomic performance were preferred over concepts focused on end use characteristics, but that diversity in farming practices can lead to different seed preferences.
Looking ahead
In 2023, several briefs will be published from scientists working in the market intelligence initiative and various partners of Market Intelligence from outside the CGIAR. An on-line repository for these briefs is being designed now. Future briefs will cover a variety of topics, from competition in maize seed markets in Kenya (based on a two year study that tracked seed sales at the retail level), methods for assessing the demand for future step-change innovations in genetic innovations, and preferences for future groundnut seed products in Tanzania, considering the needs of farmers and processors. We believe that these briefs will become a valuable communication tool to support informed decision making by crop breeders, seed system specialists, and donors on future priorities and investments by CGIAR, NARS, the private sector and non-governmental organizations (NGOs).

Anticipating appropriate and timely responses to climate variability and change from an agricultural perspective requires forecasting and predictive capabilities. In Africa, climate-related risks and hazards continue to threaten food and nutrition security.
Crop simulation models are tools developed to assist farmers, agronomists and agro-meteorologists with insights on impacts to possible management decisions. Such tools are enablers for taking an appropriate course of action where complexity exists relating to both crop and livestock production. For example, a new variety can be introduced to Zimbabwe, but its performance will differ depending on the agroecological zones of the country and the respective treatments a farmer may apply. Applying modeling tools to assess its performance can predict yield differences and facilitate the generation of recommendations for which region is most suited to the variety, water use efficiency, and crop combinations.
Earlier this month, the International Maize and Wheat Improvement Center (CIMMYT) hosted a crop modeling simulation workshop with delegates from various African countries in Harare, Zimbabwe.
âThe CGIAR Initiatives of Excellence in Agronomy (EiA) and Sustainable Intensification of Mixed Farming Systems (SI-MFS) have recognized the need to enhance modeling capacity in Africa to allow African scientists to lead in solving challenges within agricultural systems,â said CIMMYT crop scientist and coordinator of the workshop, Vimbayi Grace Petrova Chimonyo.
The workshop was facilitated by renowned global crop modeling experts to provide critical coaching support to upcoming modelers. These experts included Sue Walker, a professor at the University of the Free State, Tafadzwa Mabhaudhi, a professor at the International Water Management Institute (IWMI), KPC Rao, a lead scientist at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Dirk Raes (KU Leuven), Diego Peqeuno (CIMMYT) Â and Siyabusa Mukuhlani from the International Institute of Tropical Agriculture (IITA).
Crop models are scientific presentations of statistical knowledge about how a crop will grow in interaction with its environment. They use mathematical equations representing processes within a predefined plant system and the interactions between crops and the environment. The discipline is based on the premise that agricultural system environments are complex and not homogenous. Crop models enable decision-makers to make data-driven decisions by simulating possible outcomes to changes in a system and the configuration of production systems.
“It is quite apparent that modeling skills are scarce on the African continent. This workshop is a step toward consolidating existing capacities on the continent. If we are going to be able to close the already existing food deficit gap on the continent and meet the food requirements needed by 2050, with an estimated global population of nine billion, then we need to take modeling seriously,â said Chimonyo in her opening address at the workshop.
Due to the lack of crop modeling expertise in African states, there is a gap in capacity to build relevant crop advisory tools for farmers at a local level. This leads to poor policy formulation as decisions are based on a high degree of generalizations.
“In this modern era, we need advisories that are context specific. For example, just because a maize variety achieved a certain yield in one context doesn’t mean the same variety will achieve the same yields even if the rainfall patterns are the same. Other factors come into play, such as the soil type, temperature and other related aspects affecting the yield. Crop modeling affords advisory managers some specifications necessary to achieve high yields in different environments,” said Walker.

Speakers at the workshop focused on three models, APSIM, AquaCrop and DSSAT, and participants had the opportunity to take part in activities and ask questions face-to-face. The workshop also covered key modeling aspects such as the minimum data requirements needed to run a model, calibration and validation of models, confidence testing of results, the science involved in simulating phenological development and growth processes, water and nitrogen cycles, and the use of multi-modeling approaches.
The workshop was particularly useful for young scientists, according to Rao, allowing more experienced modelers to share their expertise. “With such an interactive platform, experienced modelers like me can demonstrate multi-modeling approaches.”
Rao presented on two main approaches. The first involved the application of different simulation models to simulate one component of a system such as crops. The second simulated the complete system by integrating various models, such as crops, livestock, and economic models, providing an opportunity to understand the synergies and trade-offs between different components of the whole farm.
Participants at the workshop expressed their satisfaction with the training provided and left with practical knowledge that they could apply in their work both in the field and in the lab.
“When I first arrived, I knew very little about modeling, but as the workshop progressed, my confidence in applying models increased. I intend to immediately apply this knowledge for the forthcoming season such that we can start making impactful contributions to the country’s food and nutrition security status,â said Birhan Abdulkadir Indris, a research officer at CIMMYT.
“I am leaving this workshop with the confidence that I will advise farmers in my circle of influence with services tailored to their needs. I have learned that crop modeling can be used for many purposes and that different models address different issues,â said Connie Madembo, a research technician at CIMMYT. âI intend to teach other fellow PhD students at the University of Zimbabwe the same things I have learnt here. As a country, we need to be at the forefront of using these models, considering Zimbabwe’s high weather variability.â
As a way forward, the trained scientists were encouraged to apply the modeling skills they had gained to address short-term problems such as yield gaps and water use efficiency and long-term challenges such as the local impacts of climate change.
âWhile more capacity training is required, starting somewhere is better than never starting,â said Mabhaudi.

As climate change effects intensify, new innovations that enable smallholder farmers to adapt are no longer an option but a necessity. Significant parts of Zimbabwe are semi-arid, receiving less than 600mm of rainfall per year. Smallholder farming communities in districts such as Buhera have embraced feed production and water conservation innovations deployed by the International Maize and Wheat Improvement Center (CIMMYT) as part of the Livestock Production Systems in Zimbabwe project (LIPS-Zim). The project, funded by the European Union and led by the International Livestock Research Institute (ILRI) and CIMMYT, champions the crop-related aspects of interventions and aims to increase livestock productivity in Zimbabweâs semi-arid regions. The project specifically aims to promote increased adoption of climate-relevant innovations in livestock-based production systems and improved surveillance and control of livestock diseases. While focused on livestock, the project is based on the premise that the performance of the livestock sector depends heavily on crop husbandry. By the same token, the livestock sector has bi-products that directly impact the productivity of crops.
Zimbabwe is a country that is well suited to mixed farming systems. Most smallholder farmers have treated livestock and crop production as mutually exclusive, but the two enterprises can have a significant complementary effect on each other.
CIMMYT Cropping Systems Agronomist Isaiah Nyagumbo is leading the development of crop husbandry innovations aimed at increasing feed production that are poised to benefit smallholder farmersâ crop productivity and enhance the conditioning of livestock, especially cattle.
Despite extension recommendations for farmers not to grow maize in these regions, studies show that 60% of the arable land is still occupied by maize. This is due to maizeâs popularity among farmers thanks to its diverse uses.
One solution is to support farmers with the most appropriate cultivars and most effective production technologies to help them be more resilient to climate change induced challenges. To contribute towards LIPS-Zimâs objective for increased feed production, CIMMYT scientists are testing and demonstrating the use of drought tolerant and nutritious maize varieties along with a wide range of leguminous species such as mucuna, dolichos lab-lab and cowpea, which are grown mostly as intercrops. Efforts are also being made to develop innovative water conservation options through reduced or no-till planting basins and tied ridging systems reinforced with different mulching options including conventional organic and synthetic artificial mulches. These are then being compared to traditional conventional mouldboard ploughing systems.

So far, the results are exciting and helping farmers to see the productivity gains from applying different technologies. Mr. and Mrs. Nyekete, smallholder farmers who volunteered to work with CIMMYT on these innovations, are optimistic about widespread adoption once the trials are concluded as the technologies can suit different levels of investment by farmers.
âWe have a lot of farmers visiting us as they observe a diversity of technologies on our plot. The artificial mulch concept is one which is very new, and farmers are curious as to how it works. They can observe for themselves that, especially when used with tied ridges, it is very effective in retaining moisture,â said Mr and Mrs Nyekete.
âThe same applies to organic mulch. Government extension workers have, over the years, been encouraging us to plant our maize under the Pfumvudza conservation agriculture model, and in it is the use of organic materials as mulch. The level of compliance in areas such as Buhera has been low, where people practice Pfumvudza without fully applying all the principles, especially soil cover. The water conservation trials are providing evidence that when one dedicates themselves to mulching their crop, whether using organic or synthetic mulches, the maize productivity is comparatively higher. As you can see, the maize plots with these water harvesting technologies are showing high vegetative growth in comparison to conventionally planted maize.â
Over the years, there has been a slow adoption of new innovations emanating from scientific research usually conducted on research stations. The use of on-farm research trials and demonstrations helps smallholder farmers to participate in the research process and co-create technologies, which shortens the adoption period and stimulates adoption at scale. This approach enables more farmers, who are not hosts, to benefit from the technologies showcased in the trials and to observe and learn from the trials. As the saying goes, âseeing is believingâ and farmers can choose the options most relevant to their own circumstances. As such, farmers can conclude for themselves which technologies bear results compelling enough for them to adopt.
Despite the artificial mulching technology demonstrating impressive results so far, Nyagumbo cautions that before the technology can be promoted at scale, more research, as well as proof of concept for these systems are needed.
âFirstly, we see that the quality of the material used has a big bearing on the ability to reduce evaporation from the soil. Secondly, some farmers have observed germination challenges due to the synthetic materials creating an attractive habitat for rodents that eat the maize seed before it germinates. Thirdly, the returns from such investments need to be justified by highly attractive economic returns arising from high yields that will also enable farmers to intensify their production systems by producing their food needs from much smaller areas. Further studies and analyses therefore need to be conducted,â said Nyagumbo.
âFurthermore, so far the idea of tied ridging combined with organic mulches also seems to offer a highly attractive option for farmers that will contribute to increased feed productivity from the enhanced grain and crop residues, since increased biomass output also means increased livestock feed availability.â
While breeding excellence is proving to be an effective method for responding to climate change through improved seed varieties and high-performance livestock breeds, new crop and livestock production technologies are required to complement the genetic gains from breeding. The crop production technologies being showcased in in Buhera along with drought tolerant and nutritious maize varieties and legumes, promise to be transformative for semi-arid regions for both crop and livestock systems.
As a warming planet desiccates crops around the world, threatening livelihoods and nutrition, farmers in Bihar, India, are boosting their wheat yields with a deceptively simple adaptation.
âFarmers can plant their wheat crop several weeks earlier, so that their wheat matures earlier and they are able to harvest their wheat before the heat gets bad,â said Amit Kumar Srivastava, a scientist with the International Rice Research Institute in India. âTraditionally, farmers in Bihar planted their wheat in mid-December. This put their crop at risk of whatâs called âterminal heatâ â high heat during a critical growth stage that impacts the yields. Weâve advised them to begin planting by November 20.â
Bihar is blessed with good soil and adequate water resources. But its yields have been lagging below Indiaâs average. Today, the average hectare of Bihar farmland produces 2.9 tons of wheat â significantly below the average yield in India of 3.4 tons.
Rising heat threatened to reduce this harvest even further. Wheat, like people, can suffer from heat stress. Researchers have found that an increase of just one-degree Celsius cuts wheat yields by 6%. In high heat conditions, wheat produces fewer, smaller grains, potentially impacting nutrition and livelihoods. Bihar, one of the poorest states in India, is considered a climate change hotspot and temperatures are expected to rise by up to 1 degree Celsius by 2050. India can ill afford declining farm yields. In fact, it needs to increase its wheat yields from around 110 million tons to 140 million tons by 2050 just to keep pace with domestic demand.
This seemingly simple adaptation was actually quite complicated to develop, explained Sonam Sherpa, a spatial agronomist with the Sustainable Agrifood Systems (SAS) program of the International Maize and Wheat Improvement Center. âIt required researchers to look at the agricultural system as a whole. We had to understand why farmers were planting so late. And we learned it was because they were waiting for their rice crop to mature. And they couldnât plant their rice crop earlier because they were waiting for the monsoon rains, which are unpredictable in Bihar. Understanding the system as a whole, led us to recommend a rice variety that matures earlier and to develop weather forecasting tools and systems that can communicate with farmers when the monsoon rains are expected. That will help farmers move forward with planting their rice earlier, allowing for an earlier harvest. And then planting and harvesting their wheat earlier.â
To demonstrate the potential of this shift, researchers established demonstration fields throughout the state and brought government officials and farmers to see the difference.
It was striking. Across the state, farmers who adopted early rice harvesting and early wheat planting grew nearly one ton more of wheat on each hectare than those who planted late â a 36% increase in yield. At the most extreme ends of the planting spectrum the difference in yield is hard to overstate; the difference in yields between the wheat planted in early November versus the wheat planted in late December was 69%. Thatâs enough of a boost to turn Bihar from a net wheat importer to a breadbasket for the region.
âSeeing is believing,â said Srivastava. As of the 2020-21 wheat growing season, an estimated 22% of farmers in the target districts â about half a million farmers with an estimated 0.83 million hectares of land â have shifted to different varieties of rice that allow them to plant their wheat earlier. Similar gains could be seen elsewhere in Eastern India, research indicates, if the rice-wheat system is managed as a system.
Researchers also established relationships with private sector seed distributors who often advise farmers and help them identify and adopt different varieties of rice that allow for earlier harvesting. âThe lesson here is that even with climate change, we can increase production by optimizing agricultural systems,â said Srivastava.
“The world is in the middle of a food crisis, driven by the supply chain disruptions during and post-Covid, climate change with increased storms, temperatures, and drought, and the Russia-Ukraine crisis, leading to a shortage of fertilizers for food crop production, which have all led to the high cost of food,” said Govaerts, highlighting that smallholders are dealing with multiple challenges at once.
He continued by describing how the aforementioned challenges to food security are worsening poverty for vulnerable people in Africa, especially smallholder farmers.
However, harnessing the continent’s potential for food production could help to alleviate poverty and food insecurity. Govaerts cited examples of where smallholder farmers have returned to producing nutritious indigenous crops such as millet, sorghum, guinea corn, groundnut, cowpeas and chickpeas, which are reaping tremendous results.
Through investments in crops, farming practices, and agricultural technologies, the potential for food production in Africa can have a huge impact on hunger and poverty.
The transboundary impacts of the COVID-19 pandemic, climate change and the Russia-Ukraine war have exposed the fragility and inequity of global food systems. But though calls for the transformation of food systems abound, there is no quick fix.

Solar powered peanut dryers in Togo are helping women-run cooperatives reduce their workload and increase their profits.
A number of West African countries have climate and soil well-suited to groundnut cultivation. In the second half of the twentieth century, the region became a world leader in peanut production. In Togo, peanuts do well, but problems with postharvest processing have kept this crop performing well below its potential.
However, the introduction of the solar powered dryers has had a significant positive impact on the production and preservation of a vital crop for the local population.
From peanut stews and sauces that are staples of national cuisine to overseas export of peanut products, there is no shortage of uses for this groundnut in Togo. However, smallholding farmers struggle to preserve their entire crop in large part because of aflatoxins, which thrive when conditions are too moist and ruin peanuts.
“Peanuts are a very perishable commodity and they can spoil if not stored properly for processing,â said AĂŻssetou Koura, president of the peanut farmer cooperative in Koumonde.
This is particularly true for smallholding peanut farmers, which in Togo includes many women. The established method for drying peanuts is to lay them out in the open air, which is a labor-intensive process that leaves the crop exposed to unexpected rains and contamination by pests. âIn the past, we suffered huge losses,â AĂŻssetou explained.
In 2021, the introduction of solar dryers began to change things dramatically for peanut farmers in cooperatives from Tovegan to Dapaong. In collaboration with the United Nations Food and Agriculture Organization (FAO), the Green Innovation Centers for the Agriculture and Food Sector (GIC) in Togo helped a local manufacturer, Guema Concept, develop solar dryer technology for local peanut farmers from plans made by the University of Hohenheim.
Launched in 2014 by Germanyâs Federal Ministry for Economic Cooperation and Developmentâs special initiative One World No Hunger, GIC collaborates with the International Maize and Wheat Improvement Center (CIMMYT) to increase agricultural mechanization in 14 countries in Africa and two in Asia.
The dryers are equipped with a ventilation system and a power kit that includes solar panels and a battery so they can operate during periods of reduced sunlight. They have a capacity of 12 kilograms and can complete a drying cycle in as little as two hours, which is about one quarter of the time a manual drying cycle takes. Depending on the solar exposure, cooperatives like the one in Koumonde can perform three or four cycles in a day.
âWe have found a solution by preserving our products with the solar dryer,” AĂŻssetou said.
GIC has helped five smallholding farmer cooperatives procure solar dyers across Togo, and more than 50 women farmers are members of these groups whose work is benefitting from this technology.
Farmers like Aicha Gaba are also increasing their profit because the solar dryers allow them to do more work with fewer laborers.
âOur cooperative dries peanuts with only two people via the solar dryer, unlike conventional open drying, which requires five people to spread, turn, monitor and collect the peanuts,â Gaba said.
âThis process reduces the workersâ wages and then saves us the money of three workers, which is a good thing for us.â
âThanks to the solar dryers offered by GIC Togo, we can freely dry our products in good conditions,â Bossa explained.
âThe products derived from the processing of peanuts are of improved quality, unlike the conventional open-drying method we used.â
All is not sunny
Despite the initial success of the solar dryers, there are challenges that remain for scaling up this innovation. The dyers are quite heavy and, for smallholding women, it can be difficult to maneuver the machines by themselves. At the same time, farmers say that â even with the greater volume the dryers have helped them achieve â they would still like a higher-capacity machine.
But even with the need for lighter, harder-working dryers, there is enormous potential for this innovation to spread to new areas, bring additional production and income to smallholding farmers (including many women), and help make groundnuts a bigger piece of the economic pie in Togo.
Research shows that inefficient storage is the main cause of staple commodity losses in the country. Despite producing 27 million tons of wheat annually worth $7.4 billion, there is less than 6 million tons of storage capacity available; around 10% of the surplus wheat is lost at a value of $740 million due to the use of unregulated conditions.
With the ability to store their commodity for an extra two or three months, farmers can increase their income by between 20 to 40 percent. Preserving the crops that have already been produced will also pass on a saving of between 15 to 20 percent to end consumers.
Hermetic technology developed by the International Maize and Wheat Improvement Center (CIMMYT), the International Rice Research Institute (IRRI) and the University of Hohenheim offers a potential storage solution by protecting the commodity from the ambient environment.
Mathuli drew attention to the innovations that are making her life easier, such as drought-tolerant maize seed varieties developed by the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agriculture and Livestock Research Organization (KALRO). She also cited her mobile phone as a vital tool, allowing her access essential information, such as weather forecasts, market prices, and technical farming support.
“In sub-Saharan Africa, more than half of the population works in agriculture,” explains Gates. “Together, they produce about 80 percent of the continentâs food supply. And most of the people doing the backbreaking farm workâlike the chores I performedâare women.”
In addition to managing her farm, Mathuli is a model farmer and Village Based Advisor with the Cereal Growers Association, encouraging other farmers to adopt new practices that will improve their productivity. “She is clearly doing a good job in this role because more than 90 percent of farmers in her area have embraced one of the new adaptation practices,” said Gates.
