Potential for independent performance information to shape farmers’ seed choice for hybrid maize: Insights from Kenya

Maize production in Kenya is a critical component of the country’s agriculture and food security. However, climate change poses a serious threat to its production. Changes in temperature and precipitation patterns can affect maize growth, reduce yields, and increase the incidence of pests and diseases.

Prolonged droughts and unpredictable rainfall can lead to crop failures, while extreme weather events can damage crops and infrastructure. As the climate continues to change, it is essential for Kenyan farmers to adopt resilient agricultural practices and more adapted seed products to safeguard maize production and ensure food security for the population.

For decades, seed companies as well as governments and donors have invested in maize hybrid breeding. Dozens of new hybrids have been made available to seed companies throughout East Africa for multiplication and distribution. These hybrids are designed and tested to outperform older hybrids in terms of yield under rainfed conditions, to include tolerance to drought and pests.

However, the potential impact of these investments has been hampered by the slow turnover of hybrids among farmers. Research has shown that, despite the availability of newer, higher-performing varieties, farmers tend to purchase older, less productive hybrids. The ‘turnover problem’ in Kenya has been described by CIMMYT researchers in a recent publication.[1]

One of the constraints responsible for the low turnover of varieties is a lack of information among farmers on the performance of the newer products. Despite advancements in the development of new seeds and the retail infrastructure to reach farmers, neither the public nor the private sector is generating and disseminating information on the performance of different maize seed products across various agroecologies. Farmers therefore have choice overload but lack objective information on relative seed performance required to make informed seed choices across seasons and growing conditions.

CIMMYT conducted a field experiment to shed light on the potential influence of seed-product performance information on farmers’ seed choices. The study involved aggregating and packaging farmer reported yield data for some seed products and presenting this to randomly selected farmers at the point of sale to assess whether the new information would influence their choice of products. The study was conducted in Kirinyaga and Embu counties where, like many parts of Kenya, farmers have access to a diverse range of maize seed products from seed companies which promise benefits like higher yields and improved resilience but lack objective information on their performance which could support their choices, including when to switch and to what.

The experiment

The study was conducted in March 2024, at the onset of the long rain season. The research team collaborated with 36 local agro-dealers in five towns and surveyed over one thousand farmers.  Farmers were intercepted as they approached the agro-dealer outlets and briefed about the study. Upon consent, they were informed on the benefits of trying something new (experimenting with varieties) and  were offered a voucher for one free bag of maize seed to encourage them to try a seed product new to them. They then were randomly assigned to two experimental groups: treatment and comparison. Participants in the treatment group were shown a chart containing product-specific yield data on maize hybrids grown in their counties (see the chart below). The chart contained farmer-reported yields from the previous year’s long rain season aggregated at two levels: county average yield and the average yield of the top 25% of farmers who realized the highest yields. The latter demonstrated the actual potential of a seed product. They were asked that, if they wished, they could choose the voucher product for experimentation from the list but they were not required to. Participants in the comparison group were offered placebo information that would not affect their seed choice: they were given some fun facts about Kenya and agriculture in Kenya. We assess the effect of the information on the choice of the bag of seed they were buying with the voucher to experiment with.

Before they made any purchases, the customers were asked about which maize seed they intended to buy. After purchase, they were interviewed again to find out which maize seeds they bought and how they had used the voucher.

 

 

 

 

 

 

What we found

Majority of the treatment farmers had a very positive evaluation of the information they received, indicating that they found it relevant and useful when making seed choice. Specifically, over 90% of them said that the information was trustworthy and easy to understand while about 80% said that the information was easy to recall. Over 80% of them disagreed that the list of varieties was too long to comprehend, the information on varieties was similar and hard to differentiate and that it was hard for them to choose a variety from the list.

This positive evaluation of the information is also reflected in their seed choices. Pre-purchases (before they entered the agrodealer store), farmers who were exposed to the performance information showed increased certainty in their choices and a higher inclination towards products listed in the product performance data, particularly the top-performing varieties. While 5% of the comparison farmers indicated that they did not know what to buy with their vouchers, only 2% of the treatment farmers suffered the same uncertainty. Such farmers relied mostly on agro-dealers to recommend a product they could experiment with.

As shown by the bar chat below, only 7% of comparison group farmers desired to use their vouchers on (or had an effective demand for) products which were the top two in the product performance lists. This increased to 27% among the information group farmers, representing an increase of 286% in the demand of top performing products.

However, although our intervention relaxed an essential constraint (product performance information) and increased the demand for some seed products, the actual purchases were subject to other constraints, stock-outs key among them. As a result, both groups showed shifts from initially desired products in their actual purchases. Even so, the treatment group maintained a stronger alignment with the listed products, exhibiting a higher likelihood of purchasing top-performing products. Only 5% of farmers in comparison group used their vouchers to purchase products which were top two in the product performance lists. This increased to 13% among farmers in the treatment group, representing a 160% increase in the likelihood of purchasing the best performing products in the lists.

Reflections

Slow varietal turnover among maize farmers in E. Africa is a pervasive problem and there is no one solution to it. This research shows that information on product performance can be an effective approach in bringing to the attention of farmers newer, more adapted and better yielding seed products. Dissemination of such information can be incorporated in extension programs, shared at the point of sale, shared through SMSs and WhatsApp messages, displayed in posters fixed in public places, etc.

The findings offer clear recommendations for future investments in seed systems development. These include the implementation of new product testing regimes to ensure quality and objectivity of performance data, testing what other information would be useful to farmers – beyond yield data, exploring new marketing options to reach farmers more effectively, and considering additional approaches to empower farmers with the knowledge they need to make informed decisions thus leading to improved agricultural productivity, resilience, and livelihoods.

Helping Colombia’s smallholder farmers to leverage and preserve maize diversity

In Colombia, maize is the most important cereal, integral to culture, tradition, and diet. In 2019, Colombia consumed 7.2 million tons of maize, a quarter of which was white-grain maize used for human food (the remainder was yellow-grain maize for animal feed, with a small portion for industrial uses). National production is concentrated in the departments of Meta, Tolima, Córdoba, Huila, and Valle del Cauca. Native and creole maize varieties—the latter comprising farmer varieties of mixed native and other ancestries—are grown for use in traditional dishes or for sale at local markets.

Due to climate change, socioeconomic pressures, and the out-migration of smallholder farmers seeking better livelihoods, native maize varieties and the unique genetic qualities those varieties embody are endangered. We aim to design strategies that benefit smallholders who wish to continue in agriculture and perhaps continue growing native varieties valued in their communities, fostering the conservation and production of native maize. CIMMYT in Mexico has already facilitated commercial linkages between chefs in Mexico City and tourist areas (for example, in the states of Oaxaca, YucatĂĄn, and the State of Mexico), sourcing blue maize landrace grain from farmers in mutually beneficial arrangements.

CIMMYT and local partners have launched an ambitious initiative to map and strengthen the value chain of native maize in the departments of Nariño, Cundinamarca, BoyacĂĄ, Valle del Cauca, and Putumayo to promote beneficial farmer-market linkages and better understand Colombia’s maize value chain. Carried out under the Nature Positive Initiative of OneCGIAR, the project is documenting maize conservation, marketing, and consumption to design a critical path that strengthens the value chain of Colombian native maize and benefits agriculture and the economy of rural Colombian communities.

Most native maize varieties in Colombia are grown on small plots for home consumption, exchange, and the sale of surplus grain. “The production is planned so that the percentage of sales is lower than consumption,” explains a farmer from Nariño. “Maize grain is sold in traditional markets, typically on Saturdays or Sundays, most often as fresh white and yellow corn.”

In such markets, farmers may also sell their grain to intermediaries, but only in the markets of Nariño is the sale of creole and native maize varieties acknowledged. Varieties include yellow Capia, white Capia, yellow Morocho, and Granizo, with Chulpe being less common. The grain purchased is used to prepare a variety of traditional dishes and beverages.

The most commonly grown varieties are intended for the market and probably the regional and urban cultural groups that consume them, such as in Guaitarilla, Nariño, where large crops of white maize are marketed through intermediaries and traders to satisfy demand.

“A variety that is not widely grown may become more prominent due to market changes—such as the rise of niche markets,” the research team notes. Good examples are the departments of Pasto, Nariño, and Cundinamarca, where maize is increasingly grown to meet demand from buyers of purple or colored maize.

We have already identified several possible niche markets for smallholder maize varieties:

  • Fair trade enterprises. They promote the commercialization of national products at fair prices for farmers, offering maize in various forms from regions such as BoyacĂĄ and Cundinamarca.
  • Restaurants. They use maize in traditional dishes, reinterpretations of Colombian cuisine, and culinary experiments.
  • Small-scale local intermediaries. Without a fixed physical space, they distribute products to end users and other businesses.

Significant challenges may hamper these and other possible market opportunities in the maize value chain. Farmers, for example, face high production costs, climate change losses, competition from neighboring countries, dependence on intermediaries for sales, and a lack of land. For their part, buyers struggle with obtaining consistent production volumes from farmers, lack storage infrastructure, and face postharvest pest and disease management challenges.

While they are compelled by the need to feed their families and, if possible, grow enough grain to sell for a profit, smallholder maize farmers have also expressed interest in preserving maize diversity and their cultural practices.

“We are not interested in growing monocultures for marketing; we grow maize out of love to continue preserving it,” comments a farmer from Nariño. Another farmer adds: “I would grow or sell more if the production were aimed at protecting agrobiodiversity, food security, sovereignty, and preserving cultural practices.”

To understand how niche markets could influence the conservation and rescue of native and creole maize in Colombia and, at the same time, design a critical path that strengthens the value chain and promotes fair and efficient niche markets, CIMMYT and its partners are conducting focus group interviews and buyer-meets-seller events. The aim is to mitigate challenges highlighted by the actors and create beneficial conditions for farmers and consumers, promoting a better future for Colombian smallholder farmers.

We deeply thank CIMMYT partners in Colombia for their contributions to this work: Andrea Gomez, Andrea PinzĂłn, and Jeisson RodrĂ­guez.

Unlocking Zambia’s maize potential through crop diversity

While maize is the primary staple food crop in Zambia, its productivity on farmers’ fields reaches on average only about 20 percent of what it could achieve with good agronomic practices. Some reasons for this inefficiency are use of traditional varieties, low fertilizer use, and ineffective weed and pest control.

Closing the gap between potential and realized yields would have major benefits for farmers in Zambia, both in terms of income and food security at the household and national levels. One possibility to increase maize productivity is by increasing crop diversity through the inclusion of legumes in maize-based farming systems. This could be done through intercropping, growing legumes in the rows between maize plants, or crop rotations and alternating maize and legumes in the same field from season to season.

CIMMYT scientists, along with collaborators from the Zambia Agriculture Research Institute (ZARI) and the University of Zambia’s School of Agricultural Science, set out to determine which cropping systems might lead to increased productivity for maize farmers in Zambia and their results were published in the journal Field Crops Research.

“There is great potential in Zambia to increase yields to help ensure food security,” said Mulundu Mwila, PhD candidate and scientist at ZARI. “We wanted to determine the cropping systems that offered the most benefits.”

Setting up the study

For this research, ZARI and CIMMYT scientists established maize-based cropping systems trials, comprising maize monocropping, and maize-legume rotations and intercrops under both ‘conventional’ tillage, and Conservation Agriculture, across 40 farms in a variety of agroecological zones in Zambia.  The team also conducted household surveys in the same communities hosting the on-farm trials to determine the share of households with enough cultivated land to benefit from the tested cropping systems.

Researchers found that the tested cropping systems produced more maize per hectare compared to non-trial host farms in the same region. The greatest positive effect uncovered was that maize-legume rotations in Zambia’s Eastern Province had the potential to increase maize yield by 1 to 2 tons per hectare, per growing season. “The Eastern Province trials showed better results because of stable and adequate rainfall amounts and distribution and because of using groundnut as a rotation crop,” said Mwila.

Researchers attributed the small effect of legumes on maize yield in the Southern Province to low levels of biomass production and nitrogen fixation, due to low and erratic rainfall, and to low residue incorporation because of livestock grazing. Conversely, the small effect of legumes on maize yield in the Northern Province might be attributed to the high rainfall amount in the region, leading to high rates of leaching of residual nitrogen during the growing season as well as the use of common beans as the preceding crop.

Finding the right amount of land

With evidence showing the potential benefits of maize-legume rotations, the availability of land is a constraint for small farms across sub-Saharan Africa, thus it is important to quantify the land area needed for farmers to implement maize-legume rotations.

“Our findings match prior research showing the benefits of maize-legume rotations in Eastern Zambia” said Silva. “However, implementing maize-legume rotations remains a challenge for many smallholders due to small farm sizes.”

Nearly 35, 50, and 70% of the surveyed farms in the Northern, Eastern, and Southern Provinces, respectively, had enough land to achieve the same level of maize production obtained on their farm with the yields of the maize-legume rotations tested in the on-farm trials. “With our findings showing increased maize yields, and our efforts to determine the amount of land needed for food and nutrition security at household level, the next steps can be to facilitate methods to disseminate this information to policy makers and to farmers that have enough land area to benefit from diversified cropping systems,” said Silva.

For farmers with not enough land to reap the benefits of maize-legume rotations, intercropping legumes within the maize has shown promising results. The researchers also call for further research to specify the contributing factors to small farms not seeing benefits from maize-legume rotations.

Mars delivers record carbon emissions reduction

CIMMYT contributes to Mars’ sustainability efforts by equipping Mexican maize producers with tools and training through the Next Generation Soil program. This collaboration supports Mars’ climate-smart agriculture initiatives, reducing agricultural greenhouse gas emissions, which make up 60% of its total GHG footprint. By promoting regenerative agriculture practices, CIMMYT helps Mars work towards a 50% GHG reduction by 2030 and achieving net-zero emissions by 2050.

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.

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

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.

Malawi faces a food crisis: why plans to avert hunger aren’t realistic and what can be done

Malawi faces a severe food crisis due to droughts from El Niño, severely impacting the maize harvest. CIMMYT experts, including Mazvita Chiduwa, highlight that importing food is the only viable solution to prevent widespread hunger. Immediate donor support is essential to avert disaster and ensure food security for the country.

Enhancing maize seed and feed security

Maize is the second most important cereal in Laos after rice, driven primarily by the demand for animal feed in neighboring countries such as China, Thailand, and Vietnam. Laos has an export-oriented maize sector, with most of the country’s production destined for these markets. The sector reached its peak in 2016, when production levels hit 6 metric tons per hectare across an area of 0.26 million hectares.

Over 90% of Laos’s maize production relies on rain-fed agriculture, with maize grain and stover serving as the primary source of feed for smallholder farmers who depend on mixed crop and livestock farming systems for their livelihoods. However, between 2016 and 2022, total maize area and production declined significantly, contracting by 64% and 70%, respectively. Several factors contributed to this decline, including volatile market prices, competition from cassava and other crops, rising production costs, and yield losses due to pests, diseases, and soil nutrient degradation because of monocropping.

Additionally, Laos relies on imported hybrid maize seed, primarily from Thailand and Vietnam, which creates a dependence on external suppliers and exposes farmers to price fluctuations. Recognizing the importance of improving maize productivity and sustainability, the Laotian government is taking steps to enhance local capacity for seed production and ensure access to affordable high-quality feed.

Enhancing local hybrid maize seed production  

Recognizing the importance of enhancing the availability and accessibility of quality maize seed and feed, CIMMYT and Laos’s National Agriculture and Forestry Research Institute (NAFRI) have initiated the evaluation of high-yielding maize hybrids for both grain and stover quality. In 2023, 12 yellow-kernel maize hybrids developed by the CIMMYT-Asia breeding program underwent evaluation in Laos. The same set of hybrids is undergoing evaluation in 2024 to identify stable and suitable germplasm. According to Siviengkhek Phommalath, director of the rice and cash crop research center at NAFRI, the 2023 evaluation provided promising results, with at least two hybrids performing better or on par with widely grown commercial ones in Laos. These hybrids exhibit high productivity, particularly in terms of grain and stover quality. However, further validation is planned for 2024, with the introduction of additional testing sites to assess performance across various environments.

Following thorough evaluations across multiple years and environments, the most suitable dual-purpose maize hybrids will be allocated to NAFRI by CIMMYT along with their parental lines, to kickstart local seed production. However, the capacity of national partners needs to be strengthened to initiate local hybrid maize seed production effectively, and this necessitates the integration and coordination of efforts among all stakeholders in the seed and feed value chains in Laos.

Capacity building across seed and feed value chains

In response to the need for capacity building in local hybrid seed production and ensuring a consistent supply of high-quality seed and feed to Laotian smallholder farmers, NAFRI has collaborated with CIMMYT under the CGIAR Sustainable Intensification of Mixed Farming Systems (SIMFS), Seed Equal, and Plant Health Initiatives to organize an international training workshop on enhancing access to quality maize seed and feed in the crop-livestock farming system of Lao PDR, which took place from May 7-9, 2024.

The three-day interactive workshop, held in Vientiane, brought together 28 specialists from various organizations, including NAFRI, Souphanou Vong University, the Upland Agriculture Research Center (UARC), Provincial Agriculture and Forestry Offices (PAFO), as well as maize seed importers and grain traders from different provinces within the country.

The first day was dedicated to understanding the challenges and opportunities of the maize seed value chain. Participants were divided into three groups based on their practical backgrounds and invited to discuss challenges, stakeholder roles, and develop actionable recommendations for better coordination across value chains. This multi-stakeholder platform aimed to comprehend the challenges and opportunities of the crop-livestock farming nexus and integrate them into a more sustainable and productive system. It also served as a forum to promote synergistic partnerships among value-chain actors in enhancing local access to good quality seed and feed. The following days focused on various essential components of quality hybrid seed production, including understanding product profiles and market segments, realizing the economics of hybrid maize seed production, seed quality assurance, management of maize pests and diseases, and enhancing maize stover quality.

A collaborative approach

Workshop participants highlighted the challenges they face in acquiring maize seeds from external sources, citing inconsistent delivery times and limited availability of preferred varieties as factors that posed significant operational constraints. “The development of a competitive domestic maize seed system would ensure timely seed supply for farmers and save resources for the nation,” said Maisong Yodnuanchan, an agripreneur from Xiangkhouang province. His concerns resonated with fellow agripreneurs Bounmy Si and Teuang Sophapmixay, from Oudomxay and Hua Phan provinces, respectively, who both acknowledged the challenges associated with the current reliance on imported seeds and the potential benefits of a sustainable, locally produced seed supply.

The training workshop offered valuable insights into addressing these concerns, providing a comprehensive overview of effective seed system development and the technical aspects of seed production applicable to a wide range of crops beyond maize. “This is the first ever training I received in my career and the knowledge gained will be directly applicable to my research activities at the UARC,” said researcher Malay Soukkhy. Recognizing the unique context of Laos compared to most of its neighboring countries with more established seed systems, AbduRahman Beshir, CIMMYT’s seed systems specialist for Asia and the lead trainer and facilitator for the workshop, emphasized the need for a collaborative approach to develop a custom solution for Laos. The workshop itself exemplified this collaborative spirit, incorporating a variety of engaging formats such as group discussions, lectures, assignments, and participant presentations. Subject matter specialists from CIMMYT offices in Nepal, India, and Kenya, as well as experts from Alliance Bioversity-CIAT and ILRI offices in Asia, shared valuable experiences applicable to Laos’s seed and feed systems.

Cementing partnerships

While addressing the participants, Timothy J. Krupnik, regional director for CIMMYT’s Sustainable Agrifood Systems Program in Asia, opened the workshop by acknowledging the invaluable support of NAFRI for organizing the event and collaborating under the CGIAR mixed farming initiative. He highlighted the imminent finalization of a Memorandum of Understanding (MoU) between CIMMYT and NAFRI, which will pave the way to further cement partnerships and establish a long term CIMMYT operations in Laos.

NAFRI’s Director General, Chanthakhone Bualaphan, presided over the workshop and emphasized the importance of continued collaboration between CIMMYT and NAFRI. Bualaphan requested CIMMYT’s continued focus on capacity building in Laos, encompassing both human resource development and institutional strengthening. She further highlighted the establishment of a specific target for domestic hybrid maize seed production, aligning with the government’s self-sufficiency goals.  To translate plans into action, Bualaphan emphasized the need for future training programs to be more action-oriented and practical. She concluded by reiterating NAFRI’s unwavering support for CIMMYT’s expanded activities in Laos, with the ultimate objective of significantly improving the livelihoods of Laotian farmers. The workshop culminated with the presentation of certificates to participants and the development of a collaborative follow-up plan for deploying well-tailored maize germplasm within the mixed farming system of Laos.

Strengthening maize value chains in Nepal

From April 3-4, 2024, CIMMYT hosted the International Conference on Strengthening Maize Value Chains in Nepal, organized in collaboration with the Ministry of Agriculture and Livestock Development, the Department of Agriculture (DOA), the National Agriculture Research Council (NARC), and the Agri Enterprise Center (AEC) of the Federation of Nepali Chamber of Commerce and Industry (FNCCI), with support from the United States Agency for International Development (USAID).

“Maize holds the potential to yield manifold benefits for farmers, the private sector, and the Government of Nepal, through the development of an efficient market system,” said Judith Almodovar, acting director of the Economic Growth Office at USAID Nepal. With this in mind, the two-day conference held in Kathmandu brought together government officials, policymakers, industry leaders, and experts from Nepal and the wider region to explore avenues for advancing the country’s maize sub-sector. It served as a platform for participants from India, Bangladesh, and Nepal, representing various functions of the maize value chain to share and exchange innovative commercial maize production, post-harvest, supply chain, and marketing models and policies aimed at improving efficiency, ensuring sustainability, and fostering competitiveness.

Addressing the opening session, Honorable Minister of Agriculture, Jwala Kumari Sah, highlighted the Government of Nepal’s priority to increase maize production and marketing, emphasizing the need to provide maize for food, feed, and fodder to boost incomes and improve livelihoods. While highlighting objectives and expectations from the conference, Country Representative for CIMMYT in Nepal, Dyutiman Choudhary, shared information about CIMMYT’s mandate and global expertise in maize science, as well as interventions to develop a maize seed-to-feed model in Nepal. The organization’s model fosters public-private farmer partnerships for commercial maize production as a key approach to develop an inclusive and sustainable maize sub-sector in the country. “As a result, maize yields have doubled in Nepal and farmer gate prices have increased by 50% in the last two years,” Choudhary explained.

A tale of two worlds: contrasting realities in southern and northern Zambia during El Niño

From the densely lush landscape of Zambia’s northern province to the arid terrain of the south, a stark reality unfolds, intensified by El Niño. Zambia’s agriculture faces contrasting realities yet potential lies in adaptive strategies, a diversified crop basket, and collaborative initiatives which prioritize farmers. Despite persistent challenges with climate variability and uneven resource distribution, the country navigates unpredictable weather patterns, emphasizing the intricate interplay between environmental factors and adaptation strategies.

Unpacking El Niño’s impact in Zambia

El Niño presents a common challenge to both southern and northern Zambia, albeit with varying degrees of intensity and duration. The 2022/2023 season had above normal rainfall amounts, with extreme weather events, from episodes of flash floods and flooding to prolonged dry spells, especially over areas in the south. In the 2023/2024 season, the southern region has already experienced irregular weather patterns, including prolonged droughts and extreme temperatures, leading to water scarcity, crop failures, and significant agricultural losses. Although the growing season is nearing its end, the region has only received less than one-third of the annual average rainfall (just about 250 mm). Dry spells of more than 30 days have been experienced and, in most cases, coincide with the critical growth stages of flowering and grain-filling. A glance at farmers’ fields paints a gloomy picture of the anticipated yield, but all hope is not lost.

In contrast, the northern province stands out receiving above-average rainfalls beyond 2,000 mm, providing a different set of challenges for crop production. In this region, incidences of waterlogging are prominent although the effects are not as detrimental as the drought in the southern province. In general, crops in the northern province promise a considerable harvest as compared to the ones in the southern province.

Maize stover and its competing use

The scarcity of resources in southern Zambia extends beyond water availability, with the competition for maize stover, a valuable byproduct used for animal feed which can also be retained on the soil surface for fertility improvement and soil moisture conservation. With limited access to alternative fodder sources, farmers face challenges in meeting the nutritional needs of their livestock while maintaining soil fertility and conserving moisture. The struggle to balance the competing demands for maize stover underscores the complex dynamics of resource management in the region. This is further worsened by the low maize stover yield expected due to the dry conditions.

Implementing fodder trials, which include cultivating fodder crops like mucuna and lablab, intercropped or rotated with maize, offers a lifeline to farmers. While maize crops may wilt under the stress of El Niño-induced droughts, leguminous crops such as mucuna, lablab, cowpea, and groundnuts exhibit resilience, thriving in adverse conditions and providing a crucial source of food, feed, soil cover, and income for farmers. The ability of legumes to withstand environmental stressors highlights the importance of crop diversification in building resilience to climate change and ensuring food security in vulnerable regions.

Conversely, in northern Zambia, the abundance of agricultural resources allows for a more sustainable utilization of maize stover. Farmers have greater access to fodder alternatives and can implement integrated farming practices to optimize the use of crop residues. This enables them to mitigate the adverse effects of soil degradation and enhance livestock productivity, contributing to the resilience of their agricultural systems.

Use of more climate-smart crops

In southern Zambia, maize stands as the main crop, often supplemented with the integration of some leguminous crops integrated to some extent, to diversify the agricultural landscape. However, the relentless and longevity grip of El Niño has taken a negative toll on maize production, despite efforts to cultivate drought-tolerant varieties. As the dry spell persists, maize plants at the critical tasseling and silking stage face an uphill battle, as the dry and hot air has adversely impacted pollen and silk development.

The dissimilarity with the northern province, where cassava thrives from abundant water, is striking. This resilient crop, known for its drought tolerance, presents a promising alternative for farmers in the southern province grappling with erratic rainfall patterns. As climate change continues to challenge traditional agricultural practices, exploring resilient crops like cassava may offer a lifeline for communities striving to adapt and thrive amidst adversity.

In response to these radically different realities, the Sustainable Intensification of Farming Systems (SIFAZ) project, a collaborative effort of CIMMYT with FAO, the Ministry of Agriculture in Zambia, and the CGIAR Initiative on Diversification in East and Southern Africa, also known as Ukama Ustawi, have jointly promoted sustainable intensification practices to enhance the resilience of smallholder farmers.

The SIFAZ project is designed around the idea that strip crops and intercrops can add nutritional and economic value to Conservation Agriculture (CA) systems for smallholder farmers in Zambia. While traditional yield metrics provide some insight across the several intercropping treatments being tested on-farm, the true benefits of these cropping systems extend beyond mere output. SIFAZ recognizes the diversification synergy, emphasizing that “two crops are better than one.”

However, the outcomes of the SIFAZ project and the CGIAR Initiative on Diversification in East and Southern Africa have varied over the years between the two regions, reflecting the discrepancy in their agricultural landscapes.

Notably, regional differences in the adoption and success of these cropping systems have become apparent. In the northern province, crop-centric approaches prevail, leading to a higher concentration of successful crop farmers. Meanwhile, in the southern province, mixed systems that incorporate mixed crop-livestock systems achieve desirable effects. These findings highlight the importance of tailoring agricultural interventions to suit the specific needs and conditions of diverse farming communities.

Navigating the complex challenges of climate change requires a multifaceted approach that acknowledges the unique realities of different regions. By embracing adaptive strategies, harnessing indigenous knowledge, and fostering collaborative partnerships, Zambia can forge a path towards a more resilient and sustainable agricultural future, where farmers thrive despite the uncertainties of a changing climate.

Seeds of change: one woman’s mission to transform her community

In the heart of Itumbula village in the Songwe district of Tanzania lives Venansia Swale, a farmer, mother, and community champion, who is turning the tide against food insecurity through the power of quality seeds. Swale has taken on the role of promoting improved seed in her community after experiencing firsthand the benefits of growing sorghum on her own farm with different seed.

“As a mother of five children, my biggest challenge is food shortage, and sorghum is our staple food,” said Swale. “Normally, I would harvest 450 kg from my three-acre farm, which isn’t enough for my family’s needs and leaves little surplus for selling. However, using quality seed this season, I harvested 990 kg. I’ve seen the benefits–not only can I feed my children for a year, but I can also earn income from the surplus.”

Swale’s efforts began to extend beyond her own farm as she championed demand creation and consolidation in her village of Itumbula. She successfully created a demand of 574 kg, becoming her community’s sole distributor of quality sorghum seed. In the 2022-2023 season, she facilitated the supply of 134 kg of quality sorghum seed and 50 kg of quality maize seed.

So far, she has reached 300 farmers in partnership with CIMMYT and the Tanzania Agricultural Research Institute (TARI), sparking a transformative movement. One local farmer said, “As a community, we have come together to embrace quality seed, and Venansia has been at the forefront of this movement. Her dedication has significantly impacted food security.”

Despite being pregnant during the 2022 “Kizazi cha Mabadiliko” (the generation that will bring change) campaign, Swale remained unwavering in her determination and passion. She exemplifies the success of the Social and Behaviour Change interventions implemented by the Centre for Behaviour Change and Communication (CBCC).

The “Kizazi Cha Mabadiliko” campaign was developed and launched by CBCC in the Mbozi and Momba districts of Tanzania, aiming to increase awareness of the benefits of improved seeds. It was also designed to challenge negative perceptions and enhance motivation for participating in agricultural activities. The campaign underscores the importance of using improved seeds as a foundational element for a prosperous future in agriculture. The strategic design of the campaign ensures the efficient distribution of behavior change tools and materials, further demonstrating its impact through Swale’s inspiring example.

Sprouting new opportunities

Despite her impressive achievements, Swale remains forward-thinking. The village extension officer notes that while farmers have adopted improved seeds, poor farming practices persist, impacting yields. Inspired and invigorated, Swale plans to revolutionize her farming practices in the upcoming season, aiming for an even more significant impact.

Besides her role as a community champion, Swale is a member of the Sifa choir in her church. Leveraging her influence, she convinced nine fellow choir members to join the intervention, where they established and managed sorghum demonstration plots in their locality. The performance of quality seed inspired the choir to enlist as seed producers, and they secured two acres of land for seed production in the 2023- 2024 season.

Venansia’s vision goes beyond her own farm; she plans to produce seeds as part of the choir group and individually, allocating an acre for seed production and two acres for grain production. Hers is a story of personal triumph, showing the impact one person can have on an entire village, and a testament to the transformative power of community-led initiatives.

“The seeds we plant today will grow into a better tomorrow for all of us,” asserts Swale.
