Pillar: Discovery

Cultivating healthier communities with provitamin A maize varieties

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

In Murehwa District, situated in Zimbabwe’s grain basket in the eastern part of the country, vitamin A deficiency is prevalent in almost all households, regardless of their wealth, reveals a study striving to quantify the nutritional yields of provitamin A maize across a diverse range of smallholder farms in Zimbabwe and to understand the potential role of improved agronomy in increasing nutritional yields. Published in the Journal of Nutrition, the study is part of a collaborative project between CIMMYT and Rothamsted Research, funded by the UK Global Challenges Research Fund, administered by the Biotechnology and Biological Sciences Research Council.

The study revealed that vitamin A deficiency is most prevalent in the wet seasons when the number of people within a household is higher. Using a range of realistic provitamin A concentration levels, modelling showed that the consumption of provitamin A maize could ensure that almost three-quarters of households reach 50% of their vitamin A requirement.

“This study highlights how provitamin A maize could make a real difference in vitamin A intake of smallholder farmers in rural areas of Zimbabwe,” said Frédéric Baudron, the lead author of this study. “And the impact could be even higher as greater gains are made through breeding and supported by better agronomy, a key determinant of nutrient concentration in the grain produced.”

Thirty households participated in the study, quantifying the composition of their diet across the main agricultural (wet) season and off (dry) season. A market study of locally available food was also conducted at the same time. In Murehwa District, almost 80% of the population is engaged in small-scale agriculture as their primary livelihood and stunting rates have increased over the past decade in this district, in sharp contrast to the rest of Zimbabwe.

Though maize is a dietary staple widely consumed in various forms in Zimbabwe, vitamin A deficiency exerts a heavy toll on people’s health, particularly in rural communities where its impact is most keenly felt. The consequences, ranging from preventable blindness in children to heightened maternal mortality rates and reduced immune function, emphasize the urgency of sustainable interventions.

The first provitamin A maize variety was released in Zimbabwe over a decade ago. Subsequent breeding efforts, aiming to develop varieties capable of providing 50% of the estimated average requirement of vitamin A, have focused on increasing the provitamin A concentration in maize and yields obtained under a range of stresses that farmers frequently encounter. To date, 26 provitamin A varieties have been released in Southern Africa. However, several key research questions remained unanswered. For instance, how prevalent is vitamin A deficiency within vulnerable populations and what is the cost of an affordable diet providing enough vitamin A? Furthermore, can the nutritional concentration of provitamin A maize grown by smallholder farmers help significantly decrease vitamin A deficiency for the majority of rural households?

The nutritional concentration of biofortified crops is related to the environment they are grown in. Biofortified maize primarily targets resource-poor farmers, holding potential in addressing nutritional gaps. However, existing research on the potential health outcomes of the consumption of provitamin A has largely been centered on maize grown in controlled environments, such as on experimental research stations or commercial farms.

The CIMMYT-led study concludes that the consumption of provitamin A maize alone would not fully address vitamin A deficiency in the short-term, calling for additional interventions such as diet diversification, industrial fortification, and supplementation. Diet diversification is one viable option highlighted by the study: modelling showed most households could obtain a diet adequate in vitamin A from food produced on their farms or available in local markets at a cost that does not exceed the current cost of their diets.

In Murehwa District, the CIMMYT-led study estimated the daily costs of current diets at USD 1.43 in the wet season and USD 0.96 in the dry season. By comparison, optimization models suggest that diets adequate in vitamin A could be achieved at daily costs of USD 0.97 and USD 0.79 in the wet and dry seasons, respectively. Another study conducted in 2023 showed that almost half of the farms in the district had knowledge of PVA maize and its benefits but did not grow it, primarily due to a limited availability of seed.

Unlocking genetic innovations through collaborative pathways

The International Maize Improvement Consortium for Africa (IMIC-Africa) held its Southern Africa field day on 25 March 2024 at Harare, Zimbabwe. IMIC-Africa, launched by CIMMYT in 2018, is a public-private partnership designed to strengthen maize breeding programs of partner institutions in Africa. As part of this initiative, CIMMYT organizes annual field days which bring together representatives from seed companies and national agricultural research system (NARS) partners across Zimbabwe and Kenya.

At the heart of the IMIC-Africa field day lies a vibrant showcase of genetically diverse materials developed from various maize breeding pipelines of CIMMYT in Southern Africa. Such events serve as a catalyst to drive innovations in maize breeding programs, deliver solutions to stakeholders, and enable seed companies and NARS partners to make informed selections tailored to local contexts.

“It is an important forum to have organized discussions with partners, and redesign—where possible—our breeding approaches to deliver targeted products to stakeholders,” said Director of CIMMYT’s Global Maize Program, One CGIAR Global Maize Breeding Lead, and One CGIAR Plant Health Initiative Lead, B.M. Prasanna. “The main stakeholders here are our partners, including seed companies and public sector national programs, through whom we reach out to farming communities.”

The significance of these field days cannot be overstated. It allows the partners to have a critical look at the breeding materials on display and undertake selections of maize lines relevant to their breeding programs. In addition, the IMIC-Africa field days enable CIMMYT team to have structured dialogues with diverse stakeholders and to review and refine breeding (line and product development) strategies and approaches.

“It is key to bridge the gap between the national programs and private sector players. This platform allows us to stay ahead in terms of research, and innovative breakthroughs in the seed sector,” added Kabamba Mwansa, principal agriculture research officer, ZARI, Zambia and Southern Africa Breeding, and seed systems network coordinator.

Highlights from the Harare field day

With an impressive array of 737 CIMMYT maize lines on display, partners at the Harare field day gained insights about the performance of different materials. The materials span early-, intermediate-, and late- maturity groups to nutritious maize breeding pipelines. This comprehensive showcase enabled seed companies and NARS partners to make informed selections, tailored to their local contexts. The material on display ranged from early generation (one or two years of testing data) to advanced generation (more than three years of testing) coming from the Southern Africa breeding pipelines targeting multiple market segments.

One of the strategic priorities of CIMMYT’s maize breeding program in Africa is improving the nutritional quality of maize. This is exemplified by the development of provitamin A-enriched maize (PVA). On display were 169 lines originating from the PVA-enriched maize breeding pipeline. The efforts underscore CIMMYT’s commitment to address regional nutritional needs through targeted breeding initiatives.

Felix Jumbe, a partner from Peacock Seeds in Malawi reflected on the importance of the IMIC-Africa partnership. “We have been part of IMIC-Africa since its inception, and we continue to appreciate the different climate-resilient lines emerging from CIMMYT maize breeding programs in Africa. Last year, we sold out of our seed as people continue to appreciate the need for resilient maize varieties. The drought-tolerant (DT) maize lines from the consortium have been a huge selling point as most farmers are happy with it,” he said.

The field day not only showcased cutting-edge breeding innovations but also offered a historical perspective by tracing the trajectory of the most popular lines taken up under IMIC-Africa from 2019 to 2023. This served as a crucial reference point for partners, enabling them to assess the performance of newly displayed lines against established benchmarks. Furthermore, partners considered the presence of trait donors as invaluable in improving resistance to key biotic stresses or tolerance to certain abiotic stresses prevalent in Africa.

CIMMYT partnership continues to add value

In the face of escalating environmental pressures, including climate change and pest infestations such as the fall armyworm (FAW), CIMMYT breeders have been working tirelessly to develop resilient varieties capable of withstanding these challenges. Partners such as SeedCo have embraced these robust varieties. For breeder Tariro Kusada, it is her second year of attending the IMIC- Africa field day. “We continue to see value in getting breeding materials through IMIC. The vigor from the lines on display is outstanding as compared to last year. We hope the vigor translates to yield.”

Danny Mfula from Synergy Zambia reinforced the value of the partnership. “It is always good to tap into CIMMYT’s germplasm to supplement what we have. We are glad that more FAW-tolerant hybrids are coming on board. We want to leverage on these developments as farmers have gone through a lot of challenges to control FAW,” he said.

As the harvest stage approaches, partners can select their material by assessing the performance of the lines from flowering to grain filling stages. Each plot’s harvest provides invaluable insights, guiding partners in their selections. Partners are also given the opportunity to view the improved maize lines from CIMMYT through a virtual gallery of ears from each plot, ensuring informed decision-making. By fostering dialogue, facilitating partnerships, and highlighting genetic innovations, the field days catalyze progress towards a more sustainable and resilient future for African agriculture.

It’s time to scale: Emerging lessons from decades of Conservation Agriculture research in Southern Africa

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

CA in action at the farmer level. (Photo: Christian Thierfelder/CIMMYT)

For decades, smallholder farmers in Southern Africa have battled the whims of a changing climate—from withered crops to yield reductions and looming food insecurity concerns. And the outlook is not improving. Based on the latest available science, the sixth assessment report of the Intergovernmental Panel on Climate Change (IPCC) reaffirms the projected negative impacts of climate change on livelihoods in Southern Africa.

Conservation Agriculture (CA) has been considered as an important step to make smallholder farming systems climate smart and resilient. The principles of CA are simple yet potent: minimal soil disturbance, crop cover, and diverse rotations, which tend to have lasting implications on rebuilding soil health, conserving moisture, and nurturing a thriving ecosystem. A strong evidence base from on-farm and on-station trials show that CA has the potential to build the adaptive capacity and resilience of smallholder farming systems to climate stress.

Yet, despite the positive results, significant scaling gaps remain. Key questions arise on what can be done to turn the tide, scale, and encourage uptake. What institutional, policy and economic incentives would enable scaling? Could mechanization be the missing link? The Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of Southern Africa (ACASA) project responds to these questions. With funding from the Norwegian Agency for Development Cooperation (NORAD) and implemented by the International Institute of Tropical Agriculture (IITA), and CIMMYT, the ACASA project goes beyond the narrow focus on promotion and technology delivery of past and ongoing interventions on CA in Southern Africa.

ACASA was designed to help stakeholders gain deeper understanding of the interactions between the socio-economic, biophysical, and institutional constraints and opportunities for adoption of CA practices. To do this, the project has undertaken extensive surveys aimed at understanding incentives, drivers, and barriers of CA adoption across Zambia, Malawi, and Zimbabwe.

Dialogues for change

In December 2023, CIMMYT collaborated with IITA and the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development of Zimbabwe to convene a highly engaging, reflective, and learning meeting, with the participation of government representatives, the private sector, and research institutes, among others. The primary objective was to share valuable insights accumulated over years of research and development on conservation agriculture in southern Africa. These insights are a result of collaborative efforts in social science, scaling, and mechanization work by CIMMYT, IITA, and extension and research partners in Malawi, Zambia, and Zimbabwe. Conversations centered on tracing the historical pathway of CA, leveraging mechanization, and identifying key enablers to transform smallholder agriculture.

Tracing the pathway of conservation agriculture

For decades, CIMMYT has been a leading force in promoting Conservation Agriculture. From the early stages in the 1990s, CIMMYT introduced CA principles and practices through on-farm and on-station field days, to undertaking robust research on biophysical impacts and developing adapted technologies in collaboration with national and global partners. As this research progressed and matured, efforts were made to integrate and focus on understanding the social and economic factors influencing CA adoption, while recognizing the significance of enabling environments. To date, linkages with mechanization and other innovations promoting CA-friendly equipment have been strengthened, ensuring inclusivity and empowerment. Questions remain around policy and institutional innovations to nudge and sustain adoption. In a nutshell, there is scope to borrow tools and methods from behavioral and experimental economics to better study and facilitate behavioral change among smallholder farmers. This snapshot highlights global efforts, grounded in scientific evidence, farmer centric approaches, and collaborative partnerships.

Insights from the field

Described as a data and evidence driven process, a notable highlight was the detailed gathering and analytical efforts using a large multi-country household survey involving 305 villages and 4,374 households across Malawi, Zambia, and Zimbabwe. The main thrust was not only to harvest data but listen to farmers and better understand their context while deciphering their decision-making processes concerning CA adoption, across the three countries. A compelling and hopeful story unfolds from the results. The adoption of CA practices such as crop residue retention, minimum tillage, crop rotation, and intercropping is much higher than previously thought, highlighting a crucial need for better targeted surveys. Key enablers to strengthen adoption include access to CA extension, hosting demonstrations, and access to credit. In addition, age, and extension in the case of Zambia were identified as important drivers of the speed and persistence of adoption. Demand for mechanization is rising, which is key to address drudgery associated with CA and to raise production efficiencies. Key recommendations centered on the need for investments in a dense network of farmer-centric learning centers that allow for experiential learning, facilitating equitable access to mechanization, promoting private sector participation, and developing integrated weed management options as weeds remain the Achilles Heel of CA adoption in the region. [1]

Emerging lessons

A deep dive on the findings reveals critical considerations for the widespread adoption of Conservation Agriculture (CA). Firstly, weed-related labor challenges pose a significant obstacle, with around 75% of farmers in three countries citing weeds as the most constraining issue during initial CA adoption. Addressing this weed management challenge is essential, emphasizing the need for environmentally safe, non-chemical solutions as a research priority. Secondly, there is a noticeable gap between scientific research on CA and farmer practices, primarily attributed to limited technical knowledge. Bridging this gap requires innovative approaches to translate scientific information into practical, farmer-centered products. Thirdly, incentivizing CA adoption through complementary input support programs, like payments for environmental services, may encourage farmers, especially when private returns are not immediate.

Fourthly, strengthening extension systems is crucial to facilitate farmer learning and bridge the awareness-to-know-how gap. Lastly, investing in improved machinery value chains can alleviate high labor costs and drudgery associated with CA practices, with economic estimates suggesting farmers’ willingness to pay for machinery hire services. These insights collectively highlight the multifaceted nature of challenges and opportunities for scaling up CA adoption.

Moving forward

ACASA’s research findings are not just numbers — they are seeds of hope. They point towards a future where CA adoption among smallholder farmers can transform the breadbasket of the three African countries, and beyond. CIMMYT and its partners remain committed to continuous learning, refining their approaches, and working hand-in-hand with farmers to nurture the CA revolution.

It will not be a pipe dream to transform agriculture in Southern Africa through CA by cultivating seeds of resilience, one at a time. This is because the experience from the region suggests that with the right political will, it is possible to mainstream CA as a critical adjunct to climate-smart agriculture strategies and resilience building. This broader institutional and political buy-in is important since CA programming cannot succeed without sector-wide approaches to removing systemic constraints to technology adoption.  A classic example is the Government-backed Pfumvudza program in Zimbabwe, which has seen adoption of planting basins conditioned on receipt of input subsidies soar to more than 90%.

Re-imagining heat tolerance traits in wheat – part 2

Written by dmedina on . Posted in In the media.

CIMMYT, along with other institutions, is enhancing wheat’s heat tolerance through four GRDC investments. These projects focus on identifying heat tolerance traits and developing scalable phenotyping technologies. Utilizing advanced tools like High Performance Liquid Chromatography (HPLC), the Dualex flavonoid meter, and hyperspectral technology, these initiatives aim to create heat-tolerant wheat varieties to ensure resilience against climate change.

Heat tolerant maize: a solution for climate change-induced 360◦ water deficits

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

Millions of smallholders in the Global South depend on maize, largely cultivated under rainfed conditions, for their own food security and livelihoods. Climate change mediated weather extremes, such as heat waves and frequent droughts, pose a major challenge to agricultural production, especially for rainfed crops like maize in the tropics.

“With both effects coming together under heat stress conditions, plants are surrounded, with no relief from the soil or the air,” said Pervez H. Zaidi, maize physiologist with CIMMYT’s Global Maize Program in Asia. “Climate change induced drought and heat stress results in a double-sided water deficit: supply-side drought due to depleted moisture in soils, and demand-side drought with decreased moisture in the surface air. “

Extreme weather events

Weather extremes have emerged as the major factor contributing to low productivity of the rainfed system in lowland tropics. South Asia is already experiencing soaring high temperatures (≥40◦C), at least 5◦C above the threshold limit for tropical maize and increased frequency of drought stress.

“In today’s warmer and drier climate, unless farmers have copious amounts of water (which might not be a sustainable choice for smallholders in the tropics) to not only meet the increased transpiration needs of the plants but also for increased evaporation to maintain necessary levels of humidity in the air, the climate change mediated weather extremes, such as heat and drought pose a major challenge to agricultural production, especially for rainfed crops like maize in lowland tropics,” said Zaidi.

To deal with emerging trends of unpredictable weather patterns with an increased number of warmer and drier days, new maize cultivars must combine high yield potential with tolerance to heat stress.

Maize designed to thrive in extreme weather conditions

CIMMYT’s Global Maize Program in South Asia, in partnership with public sector maize research institutes and private sector seed companies in the region, is implementing an intensive initiative for developing and deploying heat tolerant maize that combines high yield potential with resilience to heat and drought.

By integrating novel breeding and precision phenotyping tools and methods, new maize germplasm with enhanced levels of heat stress tolerance is being developed for lowland tropics. Over a decade of concerted efforts have resulted in over 50 elite heat stress tolerant, CIMMYT-derived maize hybrids licensed to public and private sector partners for varietal release, improved seed deployment, and scale-up.

As of 2023, a total of 22 such high-yielding climate-adaptive maize (CAM) hybrids have been released by partners throughout South Asia. Through public-private partnerships, eight hybrids are being already deployed and scaled-up to over 100,000 hectares in Bangladesh, Bhutan, India, Nepal, and Pakistan. Also, the heat tolerant lines developed by CIMMYT in Asia were used by maize programs in sub-Saharan Africa for developing heat tolerant maize hybrids by crossing these as trait donors with their elite maize lines.

Studies on the new CAM hybrids show that while their yield is like existing normal maize hybrids under favorable conditions, the CAM hybrids outperform normal hybrids significantly under unfavorable weather conditions.

“The unique selling point of the new CAM hybrids is that they guarantee a minimum yield of at least 1.0 tons per hectare to smallholder farmers under unfavorable weather when most of the existing normal hybrids end-up with very poor yield,” said Subhas Raj Upadhyay, from the Lumbini Seed Company Ltd. in Nepal.

Given the superior performance of CAM seeds in stress conditions, Nepali farmers have expressed willingness to pay a premium price: an average of 71% more with government subsidy, or at least 19% extra without a subsidy for CAM seed. Similarly, the farmers in hot-dry areas of the Karnataka state of India are ready to pay 37% premium price for CAM seed compared to normal hybrid seed. These reports strongly validate the demand of CAM seed and therefore a targeted initiative is needed to accelerate deployment and scaling these seeds in climate-vulnerable marginal agroecologies in tropics.

New innovative crops could significantly reduce agriculture’s climate change impact and environmental footprint

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

As the global population approaches the 10 billion mark, the reliance on fertilisers to boost agricultural production has become an essential, yet environmentally challenging, practice. A Century-long dependence on these additives has allowed food production to keep pace with the growth in human population. However, the use of fertilisers across various farming systems is now causing severe ecological stress. The leaching of nitrogen into natural ecosystems, coupled with the release of greenhouse gases, is pushing the Earth’s environmental limits to a critical threshold.

To address this, an ambitious new research initiative aims to shrink the nitrogen footprint of agriculture by developing a breakthrough technology based on nature’s own solutions: a natural process called biological nitrification inhibition (BNI). The Novo Nordisk Foundation has awarded CIMMYT a grant of up to USD 21.1 million to lead an innovation research initiative called CropSustaiN that is designed to reduce the nitrogen footprint of wheat cultivation.

“Success in this initiative could lead to a major shift in agricultural practices globally, benefiting both the planet and farmers’ livelihoods. In addition to using less fertiliser, cost for the farmer will be minimal because all the components are already in the seed. This initiative could, potentially, be extended from wheat cultivation to include other staple crops like maize and rice,” says Claus Felby, Senior Vice President, Biotech, Novo Nordisk Foundation.

“BNI could be a part of how we revolutionise nitrogen management in agriculture. It represents a genetic mitigation strategy that not only complement existing methods but also has the potential to decrease the need for synthetic fertilisers substantially. The mitigation potential of better nitrogen fertiliser management could be as impactful for the Global South as the Green Revolution,” explains Bram Govaerts, Director General, CIMMYT.

Revolutionary mitigation approach

Rooted in a seed-based genetic strategy, BNI leverages a plant’s innate ability to suppress soil nitrification through the release of natural compounds. This approach potentially promises to curb the use and leaching of synthetic nitrogen fertilisers—a significant contributor to greenhouse gas emissions and water pollution—without compromising wheat yield or soil vitality. The BNI-method contrasts with synthetic nitrification inhibitors and could offer a more scalable and cost-effective solution, potentially reducing nitrogen fertiliser usage by 20%, depending on regional farming conditions.

By harnessing the power of genetics in plant seeds, CropSustaiN leverages the natural process of BNI to develop new wheat varieties that require significantly less nitrogen fertiliser. Using conventional breeding, genes from wild crop relatives like wild rye, which have inherently better nitrogen use efficiency, are incorporated. CIMMYT makes such breeding products available to its global network of partners for the international public good.

The agenda for CropSustaiN includes validating BNI efficacy across diverse climates and integrating the technology into mainstream agricultural protocols. While the venture carries success risks, the potential rewards—ranging from widespread BNI adoption to valuable insights into nitrogen management—position it as a pioneering initiative. By ensuring that the seeds developed through this program are accessible to all farmers without exclusive patent rights, the Novo Nordisk Foundation is leading an inclusive approach to agricultural innovation.

CropSustaiN builds on the joint research by the Japan International Research Center for Agricultural Sciences (JIRCAS) and CIMMYT that started in 2015. The initiative has already yielded BNI wheat lines tested over three farming seasons. These innovative crops are now poised for further development and for scaling worldwide, indicating a potential paradigm shift in agricultural practices.

The Novo Nordisk Foundation has already laid the groundwork for CropSustaiN by funding related BNI research at CIMMYT, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Aarhus University, the University of Aberdeen, and the University of Copenhagen -thus fostering an ecosystem for research innovation.

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

Soil is the foundation of agriculture, and healthy soil is critical to the entire ecosystem. However, soil health is under threat today as many factors make soil unhealthy, leading to significant losses in farming. CIMMYT in India has been addressing these issues in partnership with national and international institutions, while CIMMYT’s SBP program in Türkiye aims to deliver high-yielding wheat germplasm that is resistant to SBP and supports the International Soil-Borne Pathogens Research & Development Center (ISBPRDC) of Türkiye. It also facilitates knowledge exchange and technology transfer to support joint research and development activities to improve soil health.

On arrival, the group of scientists and professors from Bihar was welcomed by Metin Türker, director general of Agricultural Research and Policies (TAGEM). Talking about the intricate nexus of agriculture, climate, and technology, Türker emphasized varietal developments to irrigation advancements and engaged in lively discussions with the group, fueled by a shared vision for agricultural sustainability.

Led by Abdelfattah A. Dababat, CIMMYT country representative in Türkiye and the leader of the SBD program, the scientists and professors from India ventured into the heart of research institutions, immersing themselves in the latest innovations in wheat improvement and plant pathology. Their journey took them from Ankara to Eskisehir and ended at the Abant Izzet Baysal University, Bolu, where they were greeted by passionate experts eager to share their knowledge. Bonds were forged amid lectures and laboratory demonstrations, and ideas ignited, paving the way for future collaborations.
