Climate change threatens to reduce global crop production, and poor people in tropical environments will be hit the hardest. More than 90% of CIMMYT’s work relates to climate change, helping farmers adapt to shocks while producing more food, and reduce emissions where possible. Innovations include new maize and wheat varieties that withstand drought, heat and pests; conservation agriculture; farming methods that save water and reduce the need for fertilizer; climate information services; and index-based insurance for farmers whose crops are damaged by bad weather. CIMMYT is an important contributor to the CGIAR Research Program on Climate Change, Agriculture and Food Security.
CIMMYT is happy to announce six new, improved tropical maize hybrids that are now available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across eastern Africa and similar agro-ecologies in other regions. NARES and seed companies are hereby invited to apply for licenses to pursue national release, scale-up seed production, and deliver these maize hybrids to farming communities.
The deadline to submit applications to be considered during the first round of allocations is 21 May 2023. Applications received after that deadline will be considered during subsequent rounds of product allocations.
The newly available CIMMYT maize hybrids were identified through rigorous, years-long trialing and a stage-gate advancement process which culminated in the 2022 Eastern Africa On-Farm (Stage 5) Trials. The products were found to meet the stringent performance and farmer acceptance criteria for CIMMYT’s breeding pipelines that are designed to generate products tailored in particular for smallholder farmers in stress-prone agroecologies of eastern Africa .

Numerous actors — from African startups to global humanitarian organizations — are responding to the continent’s food challenges. For Sub-Saharan Africa to meet its food needs as climate change persists, the region must first overcome some basic hurdles.
Harisankar Nayak, a CIMMYT supported PhD student, received significant honors from the Government of India for his PhD thesis. The Indian Council for Agricultural Research (ICAR) – Indian Agricultural Research Institute (IARI) recognized Nayak’s exceptional academic performance and thesis work during the 61st convocation ceremony held in New Delhi on February 24, 2023. The Vice President of India, Shri Jagdeep Dhankhar, presided over the ceremony. Nayak was awarded the IARI Merit medal for his thesis, “Machine learning evidence-based agronomic practices for higher yield and lower emission in rice-wheat system,” published in the esteemed journal Field Crops Research.
Nayak’s research involved comparing multiple machine learning methods to identify the primary drivers and causes of wheat yield variability in northwestern India. His findings provide important methodology to identify variables involved when one farm’s yield is less than a similar farm in the same area. With these variables classified, policymakers, government ministries, and farmers themselves can take steps to raise yield, sustainably, across the entire north-western Indo-Gangetic Plain.
Timothy Krupnik, Country Representative for Research and Partnerships and Systems Agronomist at CIMMYT-Bangladesh, and Nayak’s PhD supervisor from CIMMYT, expressed his pride in Nayak’s achievements. “I saw first-hand how much work he put into his research, and he richly deserves this honor. The same was opined by Dr C. M. Parihar, Nayak’s supervisor from IARI, Dr. M.L. Jat, former principal scientist, CIMMYT-India and Dr T B Sapkota, senior scientist, Agricultural System/Climate Change, CIMMYT. In addition, this is an excellent example of the capacity development work arising from CIMMYT’s collaborations with ICAR and IARI.”
Nayak also led research examining the sustainability of rice production in the same area of India, which determined that nitrogen use could be reduced without impacting rice yields. “To be recognized by ICAR and IARI, among many other worthy students, is a great honor,” said Nayak. “CIMMYT provided crucial material support, helping me facilitate my research. Just as important were the opportunities to collaborate with CIMMYT scientists.” Nayak’s work is vital for addressing the challenges posed by a changing climate and feeding a growing population.
Like other crops, wheat – which makes up 20 percent of the human diet – is affected by threats to the global food system from persistent population growth and economic and climate pressures. These challenges are further exacerbated by the fallout from the COVID-19 pandemic and the war in Ukraine. There is an urgent need to prioritize climate resilient wheat varieties to protect this food staple.
Some five years after HeDWIC was launched in 2014 to incorporate the most advanced research technologies into improving heat and drought tolerance of wheat, the Intergovernmental Panel on Climate Change reported that climate change was having an impact on food security through increasing temperatures, changing precipitation patterns and greater frequency of extreme weather events in its Special Report on Climate Change and Land.
“While some areas are becoming more conducive to wheat growing, crop yields are suffering in other regions around the world traditionally known as bread baskets,” said wheat physiologist Matthew Reynolds, who leads HeDWIC at the International Maize and Wheat Improvement Center (CIMMYT).
“Wheat is one of our fundamental crops, and we must spare no effort in protecting it from current and future challenges,” said Saharah Moon Chapotin, FFAR executive director. “Global collaborations are necessary to address global concerns, and these grants are bringing together international teams to share and build the science and research that will ensure the stability of this crop.”
To boost new ideas in “climate-proofing” crops, HeDWIC conducts virtual meetings that include all awarded research teams to take advantage of the collective global expertise in heat and drought resilience, leading to cross-pollination of ideas and further leverage of resources and capabilities.
In March, Reynolds led in-person discussions with some of the collaborating researchers at CIMMYT’s experimental research station on the outskirts of Ciudad Obregon, a city in Mexico’s Sonoran Desert, during CIMMYT’s annual Visitors’ Week.
Projects awarded in 2022
Exploring the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat (FluoSense4Wheat)
“The HeDWIC mini proposal allows us to explore the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat. The controlled irrigation conditions for wheat grown in Obregon give us the opportunity to quantify photosynthesis by fluorescence while drought develops. Detecting a drought-specific fluorescence response and/or the interaction between active and passive fluorescence is relevant for breeding selecting purposes as well as large spatial scale detection of drought by monitoring the plant.” – Onno Muller, Forschungszentrum Jülich, Institute of Bio- and Geosciences, Germany
Physiological basis of amelioration of heat stress through nitrogen management in wheat
“Heat stress during grain filling can restrict the availability of carbohydrates needed for grain development. India has been experiencing sudden spikes in both minimum and maximum temperatures by 3 to 5 degrees above normal from late-February onwards, which is an important time for wheat grain-filling and has resulted in declining wheat productivity. Our team is examining the ability of pre-flowering nitrogen applications to support biomass accumulation and overcome the grain-filling source (carbohydrate) limitation during heat spikes. If successful, the results could have broad-reaching benefits given that farmers are familiar with and well-skilled in using nitrogen applications regimes in crop management.” – Renu Pandey, Division of Plant Physiology, Indian Agricultural Research Institute
Can reproductive development be protected from heat stress by the trehalose 6-phosphate pathway?
“The HeDWIC funding provides a unique opportunity to test how the regulatory sugar, trehalose 6-phosphate (T6P) can protect wheat yields against increasingly common chronic and acute heat stress events. We have already shown that T6P spray increases wheat yields significantly in field conditions under a range of rainfall in wet and dry years. With increasing likelihood of heat stress events in the years ahead, in unique facilities at CIMMYT, we will test the potential of T6P to protect reproductive development from catastrophic yield loss due to chronic and acute heat.” – Matthew Paul, Rothamsted Research, UK
Investigating tolerance of heat resilient wheat germplasm to drought
“Over the last decade, we have developed heat tolerant wheat germplasm at the University of Sydney that maintains yield under terminal heat stress. In our new HeDWIC project, this material will be tested under combined drought and heat stress under field conditions. This will provide plant breeders with highly valuable information on field tested germplasm for use in accelerated breeding programs targeting combined heat and drought tolerance. The work is critical for future food security considering the inextricable link between temperature and plant water demand, and the increased frequency and intensity of heat and drought events under projected climate change.” – William Salter, University of Sydney, Australia
Novel wheat architecture alleles to optimize biomass under drought
“Wheat Rht-1 dwarfing genes were an essential component that led to spectacular increases in grain yields during the Green Revolution. Although Rht1 and Rht2 are still used widely in wheat breeding 50 years after they were introduced, they are suboptimal under drought conditions and are often associated with a yield penalty. Using a more extensive range of Rht-1 dwarfing alleles that were developed at Rothamsted, we will introduce them into CIMMYT germplasm to optimize biomass and ultimately increase grain yields under drought stress.” – Steve Thomas, Rothamsted Research, UK

Senior government officials in Zambia have embraced the rollout of the International Maize and Wheat Improvement Center’s (CIMMYT’s) new innovations which target smallholder farmers and agriculture-based value chain actors in the country.
On January 17, 2023, CIMMYT Director General Bram Govaerts met with Minister of Agriculture Reuben Mtolo Phiri. The Minister reassured Govaerts that the investments made by CIMMYT in the country had the Government’s full support.
Earlier this year, a delegation led by Cary Fowler, the US Special envoy for Global Food Security met the Minister and his team at the Government complex in Lusaka, Zambia’s capital, to deliberate on a variety of agriculture development issues concerning the country.
Govaerts’ visit came off the back of the new Accelerated Innovation Delivery Initiative (AID-I), a CIMMYT-led project funded by the United Stated Agency for International Development (USAID). The project seeks to scale up promising innovations that could transform the maize and legume value chains within the southern African region, with a focus on Zambia, Malawi and Tanzania.
“As the Government of Zambia, we intend to create a private sector driven economy for which agriculture plays a critical role. Having progressive partners like CIMMYT helps us achieve this cause and this new program is received with open arms,” said Phiri.
The aims of the AID-I project include strengthening seed systems, the promotion and adoption of stress-tolerant maize and legume varieties, demonstration of good agriculture practices that respond to the effects of climate change and addressing systemic constraints in maize and legume value chains.
Through AID-I, CIMMYT experts are working with over 20 global, regional, national and local partners including the Alliance for a Green Revolution in Africa (AGRA), Catholic Relief Services (TLC), Total Land Care (TLC), the International Water Management Institution (IMWI) and World Vegetable Center.
Also attending the meeting was AID-I Technical Lead and CIMMYT Scientist Hambulo Ngoma who discussed some of the latest project activities.
“As this project focuses on accelerated delivery, we have set up more than 40 demonstrations in eastern Zambia with the intention of showcasing stress-tolerant varieties for maize and legume under conservation agriculture. In addition, we are showcasing other good agriculture practices such as strip cropping which not only enhances intensified crop production but is a biological control for fall armyworm,” Ngoma said.

The Minister appreciated the rationale of the project and indicated that participatory variety selection for farmers was crucial if they were going to maximize their yields and returns from farming.
Phiri further emphasized that CIMMYT and partners’ investment in legume value chain strengthening came at a welcome time as upscaling soya bean production was a key priority in the Government’s strategic plan for agricultural development because of its export-ready market within the region.
“Markets such as Zimbabwe, Mozambique and Tanzania can readily take up the soya we produce, and we are looking to export legumes such as soya and groundnuts to East Africa. This project therefore fits very well within our strategic road map,” Phiri said.
The demonstration plots set up by CIMMYT experts will help farmers grow the right varieties for their agro ecologies and have greater response capabilities to the export market opportunities the Government is facilitating.
The Minister also indicated that he hoped CIMMYT would assist in strengthening the country’s capacity to deal with fall armyworm. CIMMYT Global Maize Program Director B.M. Prasanna reassured Phiri that through the Zambian Agriculture research Institute (ZARI), CIMMYT had already released three fall armyworm-tolerant varieties. He also discussed how the AID-I project would be instrumental in scaling up their uptake, especially amongst smallholder farmers who have minimal disposable income to buy enough pesticides to control the pest.
Concluding the meeting, Govaerts spoke of CIMMYT’s commitment to supporting Zambia achieve its food security and agricultural export goals.
“As CIMMYT, we want you to recognize us as a listening partner. We are of the conviction that we can only combat climate change and achieve shared prosperity through the strength of convening power, where we leverage on each other’s strength.”
As the project is focused on scaling existing promising technologies and innovations, rapid transformative results are on the horizon for the people of Zambia.
Crop breeding has the potential to significantly contribute to addressingthe global challenges of poverty, malnutrition, hunger, gender inequality, environmental degradation and climate change.Rapid population growth, climate change and market crises in low-income and middle-income countries mean that crop breeding must be far more agile and professional than ever before. Data-driven, modernized breeding with tools and technologies such as genomic selection, quantitative genetics, high-throughput phenotyping and bioinformatics, are needed toaccelerate and advance improvement in varieties.
Across the CGIAR-NARES(National Agricultural Research and Extension Systems) crop breeding networks, there is huge opportunity to reach the full potential to improve the lives of farmers and consumers: to share innovations to their full potential; reduce costs associated with services such as bioinformatics; de-fragment disparate data and incompatible technologies; apply consistent standards; and improve access to tools, technologies and shared services.
This Initiative aims to improve the genetic, economic, social and environmental performance of breeding programs across the CGIAR-NARES breeding network.
This objective will be achieved through:
Undertaking strategic modernization so that breeding schemes are designed using the most up-to-date methods, namely: quantitative genetics and computer simulation, including modeling of adoption and benefits across the breeding network, and budget forecasting for management of the portfolio and operational improvements.
Delivering cost-effective shared services through coordinating services such as genotyping and data management, leading to efficiency and greater bargaining power in purchasing or contracting equipment, software and services, ultimately enabling the generation and analysis of high-quality and consistent data across the breeding network.
Implementing performance management of consistent, connected operations through a dedicated performance management team supporting breeding programs and data management teams in describing, harmonizing and adopting standard operating protocols, workflow charts and quality controls across the networks.
Making smarter use of data, enabling CGIAR-NARES networks to share standardized data, creating larger and more powerful datasets that can be readily analyzed and interpreted.
Promoting innovation and research exchange through developing and implementing change management plans, and supporting region-specific capacity building to increase global adoption of modernized breeding tools, technologies and shared services across the network.
This Initiative will work with breeding programs serving countries in Sub-Saharan Africa and South Asia, along with Asia and Latin America. High-priority countries for the Initiative include Ghana, Kenya, Nigeria, Senegal, Tanzania, Uganda, Zimbabwe and Zambia in Africa, and Bangladesh and India in South Asia.
Proposed 3-year outcomes include:
Varieties are developed 30% faster for 70% of targeted breeding programs.
Shared services reduce costs by 25% in a majority of target programs, making modernized breeding more accessible across the global CGIAR-NARES networks.
At least 70% of targeted breeding programs make data-driven decisions using genomic, phenotypic and environmental data at more than one major decision point.
At least a 70% improvement of Initiative’s targeted breeding programs in at least 50% of impact area tracking indicators as a result of CGIAR-NARES leadership.
Increased capacity in at least 15 NARES institutions, demonstrated by increased access to tools, technologies and shared services (of more than one type) more than once a year.
A least 70% of the Initiative’s targeted continuous breeding programs increase or add at least one target to their modernization plan.
Standardized protocols shared in a common system.
Harmonized operations enabling consistent data generation.
Adoption of quality management system within facilities.
Establishment of Breeding Pipeline Improvement Monitoring System to support informative performance monitoring that reduces the complexity of breeding activities to the core metrics material for decision-making, as aligned to shared goals.
Establishment of performance monitoring system to track implementation of standardized processes and quality of operations along with modernization progress and the impacts of the resulting breeding program.
Inadequate seed supply and delivery systems, sometimes also misaligned with user and market demand, mean that smallholders often recycle seed or use older varieties, leaving them more vulnerable to pests and diseases. Small-scale farmers, especially women and other disadvantaged groups, are particularly vulnerable to climate-related challenges, such as more frequent and severe droughts and erratic rainfall. Additionally, farmers may not be well informed about varietal options available to them or may be reluctant to experiment with new varieties. These challenges threaten agricultural production and can compromise their ability to meet their own food, nutrition and income needs.
Improved varieties, innovations and approaches developed and promoted by CGIAR and partners could transform agrifood systems and reduce yield gaps, “hunger months” and other disparities. However, limited access to and use of affordable, quality seed of well-adapted varieties with desired traits, means these bottlenecks remain.
This Initiative aims to support the delivery of seed of improved, climate-resilient, market-preferred and nutritious varieties of priority crops, embodying a high rate of genetic gain to farmers, ensuring equitable access for women and other disadvantaged groups.
This objective will be achieved through:
Supporting demand-driven cereal seed systems for more effective delivery of genetic gains from One CGIAR cereal breeding, as well as improving government, private sector and farmer-based capacity to deliver productive, resilient and preferred varieties to smallholders.
Boosting legume seed through a demand-led approach that builds on growing demand for grain legumes. This multistakeholder approach will strengthen partnerships to provide efficient, more predictable and demand-led access to quality seed of new varieties.
Scaling and delivering vegetatively propagated crop seed through sustainable enhanced delivery pathways that efficiently target different market segments and farmer preferences.
Supporting partnerships (including with smallholders), capacity building and coordination to ensure uptake of public-bred varieties and other innovations by providing technical assistance for national agricultural research and extension systems (NARES) and foundation seed organizations in early-generation seed production and on-farm demonstrations.
Developing and implementing policies for varietal turnover, seed quality assurance and trade in seeds by leveraging global expertise and experience to generate both the evidence and engagement necessary to advance efficient, sustainable, and inclusive seed markets that promote varietal turnover and wider adoption.
Scaling equitable access to quality seed and traits in order to reach the unreached and provide inclusive accesswhile addressing gender and social constraints and the digital divide.
Engagement
This Initiative will work in Bangladesh, Ethiopia, India, Kenya, Mozambique, Nepal, Nigeria, Rwanda, Uganda and Tanzania as a priority,followed by other countries in Latin America, South and Southeast Asia and Sub-Saharan Africa.
Outcomes
Proposed 3-year outcomes include:
Robust tools developed and used by funders, developers, researchers and extension staff to sustainably measure and monitor key seed system metrics.
Increase of 10% in the quantity of quality seed of improved “best-fit” and farmer-preferred varieties available to farmers in representative crops and geographies due to increased capacity of seed companies and other seed multipliers (including farm-based seed actors).
Public and private seed enterprises adopting innovative and transformative models for accessing, disseminating and multiplying quality early-generation seed, reducing cost and increasing output.
Reduction of 5% in weighted average varietal age for priority crops in selected countries.
Government partners in policy design and implementation actively promote policy solutions to accelerate varietal turnover, adoption and quality seed use.
Resource-poor farmers in low-income and middle-income countries will hugely benefit from improved crop varieties that perform better in terms of nutritional quality, income generation, water and nutrient use, stability of yields under climate change, and the needs of both women and men as farmers and as consumers.
However, many smallholder farmers still grow old varieties, in part because they derive inadequate benefits from recent breeding efforts. To trigger timely adoption, new varieties must be widely available and affordable to farmers, and offer a step-change in performance through higher rates of genetic gain. A faster pace of varietal turnover is critical – to enable farmers to adapt and advance rapidly as climatic and market conditions change.
Breeding programs also need a greater focus on developing farmer- and consumer- preferred varieties adapted to distinct production environments, markets and end uses. This can be facilitated by smarter design of breeding programs; stronger partnerships between CGIAR, National Agricultural Research and Extension Systems (NARES) and small and medium enterprises (SMEs); and strengthened organizational capacity.
This Initiative aims to develop better-performing, farmer-preferred crop varieties and to decrease the average age of varieties in farmers’ fields, providing real-time adaptation to climate change, evolving markets and production systems.
The objective will be achieved through:
Re-focusing breeding teams and objectives on farmers’ needs, in particular the needs of women, through achievable product profiles and breeding pipelines targeting prioritized regions and market segments.
Reorganizingbreeding teams to drive efficiency gains through the coordinated engagement of specialists and processes using a common organizational framework, stage gates, key performance indicators and handover criteria.
Transforming towards inclusive, impactful CGIAR-NARES-SME breeding networks with empowered partners, along with customized capacity building, standardized key performance indicators, and by dividing labor and resources across partners according to comparative advantage and aligned with national priorities.
Discovering optimum traits and deployments through agile, demand-driven and effective trait discovery and deployment pipelines, and development of elite donor lines with novel and highly valuable traits.
Acceleratingpopulation improvement and variety identification through optimizing breeding pipelines (trailing, parent selection, cycle time, use of Breeding Resources tools and services, etc.), with the goal of assuring all programs deliver market-demanded varieties that deliver greater rates of genetic gain per dollar invested.
Engagement
This Initiative will work with breeding programs serving countries in Sub-Saharan Africa, and South Asia, along with Asia and Latin America.Priority countries for the Initiative includeGhana, Kenya, Nigeria, Senegal, Tanzania, Uganda, Zambia and Zimbabwe in Africa, and Bangladesh and India in South Asia.
Outcomes
Proposed 3-year outcomes include:
At least 75% of breeding pipelines are oriented towards specific market segments, enabling greater focus on farmers’ needs, drivers of adoption, distinct impact areas and the strategic allocation of resources.
At least 70% of breeding pipelines use a revised organizational framework that provides operational clarity and effectiveness for specialized teams pursuing breeding outputs.
At least 80% of the breeding networks have implemented documented steps toward stronger partnership models where NARES and SMEs have increased breeding capacity, and make greater scientific, operational and decision-making contributions to the breeding process.
At least 50% of breeding pipelines are supported by a dedicated trait discovery and deployment program that delivers high-impact traits in the form of elite parental lines.
At least 70% of breeding pipelines have increased the rate of genetic gain in the form of farmer-preferred varieties, with at least 50% providing significantly improved varieties delivered to seed system recipients.
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.
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.
This Initiative aims to maximize CGIAR and partners’ 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 CGIAR’s 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.
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.
Developing pipeline investment cases by estimating the potential impact and return on investment across CGIAR’s five impact areas of the portfolio of breeding pipelines serving the market segments and developing recommendations for the portfolio optimization and prioritization.
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.
Engagement
This Initiative has a global and regional focus, with countries being prioritized as a result of the Initiative’s work.
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.
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.
At least five seed suppliers, food companies and NGOs in prioritized regions use market and behavioral intelligence from the Initiative in strategic decision-making.
At least three research leaders and investors make investment decisions using pipeline investment cases and the Initiative’s 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.

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.
“The 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,” 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) 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,” 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,” 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,” said Connie Madembo, a research technician at CIMMYT. “I 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.”
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.
“While more capacity training is required, starting somewhere is better than never starting,” 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 Zimbabwe’s 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 farmers’ 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 maize’s 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-Zim’s 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.
“We 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,” said Mr and Mrs Nyekete.
“The 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.”
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, “seeing is believing” 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.
“Firstly, 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,” said Nyagumbo.
“Furthermore, 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.”
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.
“Farmers 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,” said Amit Kumar Srivastava, a scientist with the International Rice Research Institute in India. “Traditionally, farmers in Bihar planted their wheat in mid-December. This put their crop at risk of what’s called ‘terminal heat’ – high heat during a critical growth stage that impacts the yields. We’ve advised them to begin planting by November 20.”
Bihar is blessed with good soil and adequate water resources. But its yields have been lagging below India’s average. Today, the average hectare of Bihar farmland produces 2.9 tons of wheat – 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. “It 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 couldn’t 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.”
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 – 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%. That’s enough of a boost to turn Bihar from a net wheat importer to a breadbasket for the region.
“Seeing is believing,” said Srivastava. As of the 2020-21 wheat growing season, an estimated 22% of farmers in the target districts – about half a million farmers with an estimated 0.83 million hectares of land – 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. “The lesson here is that even with climate change, we can increase production by optimizing agricultural systems,” said Srivastava.
Arun Kumar Joshi, CIMMYT Country Representative for India, CIMMYT Regional Representative for South Asia and Managing Director of the Borlaug Institute for South Asia (BISA), predicted a bumper year for wheat in India.
“The feedback so far I am getting is that there will be record production of wheat,” he said. “The reason is that the area of cultivation has increased. According to government estimates, wheat has been sown in more than 34 million hectares so far in this rabi season.”
Reasons for this include no current threat from locusts or diseases, appropriate levels of soil moisture and humidity, and farmers shifting to planting crops earlier, explained Joshi.
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 continent’s food supply. And most of the people doing the backbreaking farm work—like the chores I performed—are 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.
