Theme: Nutrition, health and food security

As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the world’s food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.

Achieving widespread food and nutritional security for the world’s poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.

Early maturity products popular among farmers in Kenya

Across all production environments in Kenya, early-maturity products demonstrate strong sales. This was revealed in a recent study by the CGIAR Initiative on Market Intelligence. During the long-rains season, farmers in higher rainfall production environments—wet, mid and high altitudes—purchased early-maturity seed products despite potentially lower yields. Also, the short-rains season, which represents almost one-fourth of total maize seed sales, was dominated by early-maturity products.

These insights were obtained through a panel of maize-seed sales data from 722 agrodealers in Kenya during two short-rains seasons and three long-rains seasons in 2020–2022. The study also offers insights into the extent the maturity level of seed products, purchased by farmers in Kenya, aligns with the production environment where they were sold. Market Intelligence applies eight criteria to identify seed product market segments (SPMSs) for CGIAR crop breeding. In the application of these criteria to maize in East Africa, two conditions distinguish the segments: production environment and maturity level. The other criteria do not vary. A key indicator for prioritizing breeding investments across segments is the relative size of SPMSs. In the case of maize, and other crops, teams generally use geospatial data to identify the area of production environments, with the assumption that farmers in each production environment would use the seed product with the maturity level designed for that environment.

The paper contends that a stronger focus on using sales data to inform breeding decisions in maize, and potentially other crops where retailers play an important role in seed distribution, should become a priority for market intelligence. Future work will engage stakeholders in maize seed systems in other countries of East Africa about the changes in demand for earlier-maturing products and the implications for segmentation.

Evaluating Agro-ecological Management Options for Fall Armyworm in Zimbabwe

Fall armyworm (Spodoptera frugiperda J.E. Smith) has emerged as a major threat to farming communities across Africa, including Zimbabwe. This destructive pest feeds on a wide range of crops, including maize, posing a significant challenge to food security. To combat this pest, the project “Evaluating Agro-ecological Management Options for Fall Armyworm in Zimbabwe” was initiated in October 2018 with support from USAID. It aims to address research gaps on fall armyworm management and cultural control in sustainable agriculture systems.

The project has implemented research trials in ten (10) districts across Zimbabwe, with work reaching close to 9,000 beneficiaries in target areas being exposed and applying new control practices that reduce the damage of FAW without heavily relying on chemical pesticides. This has been supported by a strong focus on agronomy trainings, field days, documentation, education through technical videos, knowledge sharing, and developing farmer manuals. In addition, the project supports Farmer Field Schools involving all relevant players in the farming communities to mainstream cultural practices in fall armyworm management.

Key objectives

The overall objective is to explore climate-adapted push pull systems and low-cost cultural control options for smallholder farmers in Zimbabwe. This project focused on research trials in Murehwa (Mashonaland East) and Mhondoro Ngezi (Mashonaland West), where the proof of concept was developed. After the inception phase it expanded to establishing demonstration sites and Farmer Field Schools in the Manicaland province, conducting trainings with farmers, and promoting knowledge sharing with Agritex officers and engaging with all relevant players in the target localities. Through continuous research and collaborative efforts, this project aims to develop sustainable and eco-friendly strategies to manage all armyworm infestations.

Millers in Nigeria laud the release to farmers of co-developed, CIMMYT-derived wheat varieties

Nigerian wheat scientists and millers recently recognized and thanked CIMMYT for its contributions to four new wheat varieties released to farmers, citing the varieties’ exceptional performance in field trials and farmers’ fields across national wheat-growing regions.

“The release of these four wheat varieties, uniquely tailored to suit our local conditions, has marked a significant milestone in enhancing food security and farmer livelihoods,” said Ahamed T. Abdullahi, agronomist for wheat value chains at the Flour Milling Association of Nigeria (FMAN), in a recent message to CIMMYT’s Global Wheat program. “The improved characteristics, such as higher yield potential, enhanced disease resistance, and adaptability to local climatic conditions, have significantly boosted wheat productivity. Moreover, the quality profiles of these varieties, as expressed in Nigeria, comply fully with the standards required by the local industry.”

Two of the varieties are bread wheat and yield up to 7 tons of grain per hectare, according to a recent Nigeria Tribune article. The other two are durum wheat, a species grown to make pasta and foods such as couscous and tabbouleh. One of those, given the name LACRIWHIT 14D in Nigeria, was from a CIMMYT wheat line selected for its novel genetic resistance to leaf rust and high-yield potential under irrigated conditions. It was also released in Mexico under the name CIRNO C2008 and is the country’s number-one durum wheat variety, according to Karim Ammar, a wheat breeder at CIMMYT.

“Aside from its high yield potential, it has considerable grain size and an aggressive grain fill that is expressed even under extreme heat,” explained Ammar. “These characteristics have certainly helped its identification as outstanding for Nigerian conditions.”

Writing on behalf of FMAN and the Lake Chad Research Institute (LCRI) of Nigeria’s Federal Ministry of Agriculture and Rural Development, Abdullahi said, “We deeply appreciate the expertise and support provided by CIMMYT throughout the development and release process. Your team’s technical guidance on the access to germplasm has played a crucial role in equipping our farmers and extension agents with the necessary skills and resources for successful wheat cultivation.”

Nigeria has a fast-growing population which, coupled with increasing per capita demand for wheat, has made increasing wheat production a national priority, according to Kevin Pixley, director of the Dryland Crops and Global Wheat programs at CIMMYT.

“Until recently, Nigeria produced only 2% of the wheat it consumes, but potential exists to double the current average yield and expand wheat production by perhaps 10-times its current area,” said Pixley. “New wheat varieties will be essential and must be grown using sustainable production practices that improve farmers’ livelihoods while safeguarding long-term food security and natural resources.”

Abdullahi said the release of the varieties demonstrated the power of collaborative research and highlighted the potential for future collaborations. “We look forward to continued collaborations and success in the pursuit of sustainable food systems.”

He also extended his appreciation to the AID-I project, recognizing that this initiative is not only important but also timely, as it serves to meet the urgent need for promoting and enhancing the availability of nutritious vegetables in Zanzibar.

CGIAR Initiative on Diversification in East and Southern Africa

East and Southern Africa is a climate hotspot, with more than US$45 billion in agricultural production at risk from higher temperatures, shorter growing seasons and more extreme droughts and floods. Maize, a staple crop covering up to 75% of cropland in parts of the region, is particularly vulnerable and is projected to face yield declines of 15%, among other climate impacts if no adaptation measures are taken. Many of the affected areas already have serious levels of hunger and malnutrition, with the highest burden experienced by women and youth from marginalized and vulnerable communities. If these systems are sustainably diversified, they can contribute to stabilizing regional and global agrifood systems.

The next decade will be critical for strengthening food, land and water systems in East and Southern Africa. The agribusiness ecosystem for both regions has been identified as a critical engine for agricultural and economic development, climate change adaptation and gender and youth empowerment. Investment in innovation, capabilities and supportive environments will be essential for driving sustainable growth.

Objective

This Initiative aims to support climate-resilient agriculture and livelihoods in 12 countries in East and Southern Africa by helping millions of smallholders intensify, diversify and reduce the risks in maize-based farming through improved extension services, small and medium enterprise development, supporting governance frameworks and increased investment with a gender and social inclusion lens.

Activities

This objective will be achieved through:

  • Diversifying and sustainably intensifying production by assessing needs and options for the introduction of crops, livestock, mechanization and irrigation, applying innovations in value chains and building capacity while scaling to larger farming communities.
  • Reducing risk and digitalizing value chains by co-designing and delivering “Innovation Package” bundles of digital agro-advisory systems and research management products — including mobile apps, TV programs and social media — to build resilience and improve productivity.
  • Supporting and accelerating value chain business enablers in maize mixed systems by using CGIAR’s expertise and partner network to unlock access to funding, investment and tailored technical assistance.
  • Promoting the governing and enabling of multifunctional landscapes for sustainable diversification and intensification with a focus on strengthening the evidence base for decision-makers.
  • Empowering and engaging women and youth in agribusiness ecosystems by mapping challenges and opportunities to address gender and social inequality and applying inclusive and coordinated interventions for transformative change.
  • Scaling innovations and coordinating CGIAR and partner activities in the region through a scaling hub that uses the “scaling readiness” approach to inform, activate and bring to scale innovations that respond to regional or country demand.

LIPS-Zimbabwe empowers farmers through innovative intercropping trials

Since 2021, CIMMYT, in partnership with the International Livestock Research Institute (ILRI), the French Agricultural Research Centre for International Development (CIRAD), and the University of Zimbabwe’s Department of Veterinary, has been working in rural communities of Zimbabwe, as part of the Livestock Production Systems in Zimbabwe (LIPS-Zim) project. The activity is led by Zimbabwe’s Department of Research and Specialist Services and is at the forefront of introducing new agricultural innovations to local farmers.

One of their most impactful initiatives has been the intercropping trials involving maize and various legumes including jack bean, mucuna, lablab, and pigeon pea. This groundbreaking approach has not only transformed the lives of farmers but has also had a positive impact on the overall health of livestock.

Various leguminous fodder crops have been promoted widely as sources of high-quality protein feed in mixed crop-livestock systems of Zimbabwe. However, to diversify and increase the options for the drier regions, the LIPS-Zim project is testing new leguminous crops such as jack bean and pigeon pea, which are well-adapted to dry conditions.

Netsai Musekiwa, a farmer in the town of Mutoko, has been part of the LIPS-Zim project for the past two seasons, and is currently conducting intercrop trials with jack bean. “Since I started intercropping maize with jack bean, I have been amazed by the results and will continue on this path. The jack bean plants have shown strong tolerance to prolonged dry spells and heat stress,” she said. “Next season, I plan to extend my plot to harvest more jack bean.” These words of encouragement on intercropping maize with jack bean have also been largely echoed by many other farmers in Mutoko and Buhera during the feedback meetings held in October 2023.

What is intercropping and how beneficial is it to farmers?

Intercropping is an agricultural practice of growing two or more crops together on the same field simultaneously to maximize land use and enhance productivity. As different crops have different growth patterns and nutrient requirements, intercropping can help optimize resource utilization and boost overall crop output.

In addition, intercropping reduces the risk of climate induced crop failure as well as minimizing pest damage, enhances soil fertility by diversifying the root system, and can provide additional income streams to farmers.

The science behind jack bean and pigeon pea

Jack bean (canavalia ensiformis) and pigeon pea (cajanus cajan) are leguminous crops valued for their nitrogen-fixing abilities which aides in improving soil fertility. Both jack bean and pigeon pea have deep root systems, making them ideal candidates for the dry semi-arid conditions in Zimbabwe.

Pigeon pea is known for its drought-tolerance and produces edible seeds used in various culinary dishes and is a source of both food and feed. Jack bean is used as a forage crop for livestock, providing nutritious feed.

“Jack bean seeds contain a toxic compound called canavanine, which can be harmful when consumed in large quantities or not properly processed. To make jack beans safe for consumption, it must be boiled, soaked, or fermented,” said Isaiah Nyagumbo, cropping systems agronomist at CIMMYT. “We have introduced many farmers to the best practices for handling jack beans and have opened up new possibilities for its utilization in sustainable farming practices.”

While some farmers were intercropping with jack bean, others explored pigeon pea as an alternative. “I liked the intercropping of maize and pigeon pea on my plot. I am assured of getting nutritious food both for my family and livestock. After harvesting, I usually take the branches, then put them in the shade and dry them to retain the nutritional value. I occasionally give some to my goats during the dry season when feed from natural pastures is scarce, and my goat herd has risen to 12 goats,” said Fungai Kativu, a farmer in Mutoko.

Building capacity of local farmers

To narrow the knowledge gap and highlight the potential of such feed options, LIPS-Zim has also been spearheading the establishment of community level learning centers. These centers are a knowledge hub to local farmers, providing practical knowledge, facilitating the sharing of different perspectives while nurturing working as groups with a common vision. This “farmer learns by seeing” approach has been a success in the community.

Through this initiative, farmers have not only witnessed increased productivity but have also gained the necessary skills and knowledge to adapt to the changing agricultural landscape. “Intercropping leguminous crops with maize has shown great potential in improving food security and livestock feed production in Zimbabwe’s farming communities, especially in areas prone to heat and drought,” said Nyagumbo.
