Heat tolerant maize hybrids: a pursuit to strengthen food security in South Asia

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

After a decade of rigorous effort, CIMMYT, along with public-sector maize research institutes and private-sector seed companies in South Asia, have successfully developed and released 20 high-yielding heat-tolerant (HT) maize hybrids across Bangladesh, Bhutan, India, Nepal, and Pakistan. CIMMYT researchers used a combination of unique breeding tools and methods including genomics-assisted breeding, doubled haploidy (a speed-breeding approach where genotype is developed by chromosome doubling), field-based precision phenotyping, and trait-based selection to develop new maize germplasm that are high-yielding and also tolerant to heat and drought stresses.

While the first batch of five HT maize hybrids were released in 2017, by 2022 another 20 elite HT hybrids were released and eight varieties are deployed over 50,000 ha in the above countries.

In South Asia, maize is mainly grown as a rainfed crop and provides livelihoods for millions of smallholder farmers. Climate change-induced variability in weather conditions is one of the major reasons for year-to-year variation in global crop yields, including maize in Asia. It places at risk the food security and livelihood of farm families living in the stress-vulnerable lowland tropics. “South Asia is highly vulnerable to the detrimental effects of climate change, with its high population density, poverty, and low capacity to adapt. The region has been identified as one of the hotspots for climate change fueled by extreme events such as heat waves and intermittent droughts,” said Pervez H. Zaidi, principal scientist at CIMMYT.

Heat stress impairs the vegetative and reproductive growth of maize, starting from germination to grain filling. Heat stress alone, or in combination with drought, is projected to become a major production constraint for maize in the future. “If current trends persist until 2050, major food yields and food production capacity of South Asia will decrease significantly—by 17 percent for maize—due to climate change-induced heat and water stress,” explained Zaidi.

From breeding to improved seed delivery–the CIMMYT intervention

In the past, breeding for heat stress tolerance in maize was not accorded as high a priority in tropical maize breeding programs as other abiotic stresses such as drought, waterlogging, and low nitrogen in soil. However, in the last 12–15 years, heat stress tolerance has emerged as one of the key traits for CIMMYT’s maize breeding program, especially in the South Asian tropics. The two major factors behind this are increased frequency of weather extremes, including heat waves with prolonged dry period, and increasing demand for growing maize grain year-round.

At CIMMYT, systematic breeding for HT maize was initiated under Heat Stress Tolerant Maize for Asia (HTMA), a project funded by the United States Agency for International Development (USAID) Feed the Future program. The project was launched in 2013 in a public–private alliance mode, in collaboration with public-sector maize research institutions and private seed companies in Bangladesh, Bhutan, India, Nepal, and Pakistan.

The project leveraged the germplasm base and technical expertise of CIMMYT in breeding for abiotic stress tolerance, coupled with the research capacity and expertise of the partners. An array of activities was undertaken, including genetic dissection of traits associated with heat stress tolerance, development of new HT maize germplasm and experimental hybrids, evaluation of the improved hybrids across target populations of environments using a heat stress phenotyping network in South Asia, selection of elite maize hybrids for deployment, and finally scaling via public–private partnerships.

Delivery of HT maize hybrids to smallholder farmers in South Asia

After extensive testing and simultaneous assessment of hybrid seed production and other traits for commercial viability, the selected hybrids were officially released or registered for commercialization. Impact assessment of HT maize hybrid seed was conducted in targeted areas in India and Nepal. Studies showed farmers who adopted the HT varieties experienced significant gains under less-favorable weather conditions compared to farmers who did not.

Under favorable conditions the yield was on par with those of other hybrids. It was also demonstrated that HT hybrids provide guaranteed minimum yield (approx. 1 t ha-1) under hot, dry unfavorable weather conditions. Adoption of new HT hybrids was comparatively high (19.5%) in women-headed households mainly because of the “stay-green” trait that provides green fodder in addition to grain yield, as women in these areas are largely responsible for arranging fodder for their livestock.

“Smallholder farmers who grow maize in stress vulnerable ecologies in the Tarai region of Nepal and Karnataka state in southern India expressed willingness to pay a premium price for HT hybrid seed compared to seed of other available hybrids in their areas,” said Atul Kulkarni, socioeconomist at CIMMYT in India.

Going forward–positioning and promoting the new hybrids are critical

A simulation study suggested that the use of HT varieties could reduce yield loss (relative to current maize varieties) by up to 36% and 93% by 2030 and by 33% and 86% by 2050 under irrigated and rainfed conditions respectively. CIMMYT’s work in South Asia demonstrates that combining high yields and heat-stress tolerance is difficult, but not impossible, if one adopts a systematic and targeted breeding strategy.

The present registration system in many countries does not adequately recognize the relevance of climate-resilience traits and the yield stability of new hybrids. With year-to-year variation in maize productivity due to weather extremes, yield stability is emerging as an important trait. It should become an integral parameter of the registration and release system.

Positioning and promoting new HT maize hybrids in climate-vulnerable agroecologies requires stronger public–private partnerships for increasing awareness, access, and affordability of HT maize seed to smallholder farmers. It is important to educate farming communities in climate-vulnerable regions that compared to normal hybrids the stress-resilient hybrids are superior under unfavorable conditions and at par with or even superior to the best commercial hybrids under favorable conditions.

For farmers to be able to easily access the new promising hybrids, intensive efforts are needed to develop and strengthen local seed production and value chains involving small-and medium-sized enterprises, farmers’ cooperatives, and public-sector seed enterprises. These combined efforts will lead to wider dissemination of climate-resilient crop varieties to smallholder farmers and ensure global food security.

Zambuko Livelihoods Initiative

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

Persistent vulnerability to frequent climate-related shocks, exacerbated by the effects of climate change poses a continual threat to the capacity of communities to secure an adequate and nutritious food supply throughout the year. The R4 Rural Resilience Initiative, led by the World Food Programme (WFP), aims to enable vulnerable, smallholder farmers to increase their food security, income, and resilience by managing climate-related risks. Expanding on the success of R4, WFP launched the Zambuko Livelihoods Initiative, a comprehensive program supported by United States Agency for International Development (USAID). This initiative strategically concentrates on fostering social cohesion within communities, advancing crop and livestock production, and facilitating improved access to financial resources.

In a collaborative endeavor, CIMMYT is leading the implementation of the climate-smart agriculture and mechanization components of the Zambuko program, with a specific focus on Masvingo Rural (Ward 15) and Mwenezi (Ward 6) in Zimbabwe. Focused on mitigating the impact of climatic shocks and stresses, the initiative aims to empower local farmers, improve agricultural practices, and foster sustainable livelihoods. This collaborative effort represents a crucial step towards building resilience in the face of climate challenges, offering a holistic approach to enhancing the adaptive capacity of vulnerable communities.

Key objectives

The overall objective is to diversify and strengthen climate-resilient livelihoods, while mitigating household vulnerability to recurring shocks, such as droughts and floods.

CIMMYT oversees interlinked goals which are –

  1. Viable conservation agriculture (CA) and mechanization options are tested and expanded in rural farming communities.
  2. Seed and fodder options are tested and available for wider use by smallholders.
  3. Increased smallholder farmer knowledge and capacity to implement climate-smart agriculture interventions to build resilience.

Soybean rust threatens soybean production in Malawi and Zambia

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

Soybeans are a significant source of oil and protein, and soybean demand has been increasing over the last decade in Malawi and Zambia. Soybean contributes to human nutrition, is used in producing animal feed, and fetches a higher price per unit than maize, thus serving as a cash crop for smallholder farmers. These are among the main factors contributing to the growing adoption of soybean among smallholder producers. In addition, soybean is a vital soil-fertility improvement crop used in crop rotations because of its ability to fix atmospheric nitrogen. To a large extent, soybean demand outweighs supply, with the deficit covered by imports.

Soybean production in sub-Saharan Africa is expected to grow by over 2% per annum to meet the increasing demand. However, as production increases, significant challenges caused by diseases, pests, declining soil fertility, and other abiotic factors remain. According to official government statistics, Zambia produces about 450,000 tonnes of soybean per annum, with an estimated annual growth of 14%. According to FAOSTAT, this makes Zambia the second largest soybean producer in the southern African region. Although soybean was traditionally grown by large commercial farmers in Zambia, smallholders now account for over 60% of the total annual soybean production.

Production trends show that smallholder soybean production increased rapidly in the 2015–2016 season, a period that coincided with increased demand from local processing facilities. As smallholder production continued to increase, in 2020, total output by smallholder farmers outpaced that of large-scale farmers for the first time and has remained dominant over the last two seasons (Fig 1). However, soybean yields among smallholder farmers have remained low at around 1 MT/HA.

Soybean production in the region is threatened by soybean rust caused by the fungus Phakopsora pachyrhizi. The rust became prevalent in Africa in 1996; it was first confirmed in Uganda on experimental plots and subsequently on farmers’ fields throughout the country. Monitoring efforts in the U.S. have saved the soybean industry millions of dollars in fungicide costs due to the availability of accurate disease forecasting based on pathogen surveillance and environmental data.

Soybean rust disease is spread rapidly and easily by wind, and most available varieties grown by farmers are susceptible. The above-normal rainfall during the 2022–2023 season was conducive to the spread of the fungus. A recent survey of over 1,000 farm households shows that 55% and 39% of farmers in Zambia and Malawi, respectively, were affected by soybean rust during the 2022–2023 season. The lack of rust-tolerant varieties makes production expensive for smallholder farmers who cannot afford to purchase fungicides to control the pathogens. It is estimated that soybean rust can cause large yield losses of up to 90%, depending on crop stage and disease severity. Symptoms due to soybean rust infection may be observed at any developmental stage of the plant, but losses are mostly associated with infection from the flowering stage to the pod-filling stage.

Mitigation measures using resistant or tolerant varieties have been challenging because the fungus mutates very rapidly, creating genetic variability. Although a variety of fungicides effective against soybean rust are available, the use of such fungicides is limited due to the high cost of the product and its application, as well as to environmental concerns. Due to this restricted use of fungicide, an early monitoring system for detecting rust threats for steering fungicide might only be relevant for large-scale producers in eastern and southern Africa. With the massive increase in the area under soybean production, soybean rust is an important disease that cannot be ignored. Host-plant resistance provides a cheaper, more environmentally friendly, and much more sustainable approach for managing soybean rust in smallholder agriculture that characterizes the agricultural landscape of eastern and southern Africa.

To advance the use of rust-tolerant varieties, the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, is presently concluding surveys to assess farmers’ demand and willingness to pay for rust-tolerant varieties in Malawi and Zambia. The results from this assessment will be valuable to seed companies and last-mile delivery partners to gain a better understanding of what farmers need and to better serve the farmers.  This coming season AID-I will include rust tolerant varieties in the mega-demonstrations to create awareness about new varieties that show some tolerance to rust.

Tackling fall armyworm with sustainable control practices

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

Typically looking like a small caterpillar growing up to 5 cms in length, the fall armyworm (FAW, Spodoptera frugiperda) is usually green or brown in color with an inverted “Y” marking on the head and a series of black dots along the backs. Thriving in warm and humid conditions, it feeds on a wide range of crops including maize, posing a significant challenge to food security, if left unmanaged. The fall armyworm is an invasive crop pest that continues to wreak havoc in most farming communities across Africa.

The first FAW attack in Zimbabwe was recorded around 2016. With a high preference for maize, yield losses for Zimbabwe smallholder farmers are estimated at US$32 million. It has triggered widespread concern among farmers and the global food system as it destroyed large tracts of land with maize crops, which is a key staple and source of farmer livelihood in southern Africa. The speed and extent of the infestation caught farmers and authorities unprepared, leading to significant crop losses and food insecurity.

Exploring the destructive FAW life cycle

It undergoes complete metamorphosis, progressing through four main stages including egg, larva, pupa, and adult. Reproducing rapidly in temperatures ranging from 20 to 38°C, moist soil conditions facilitate the egg-laying process, while mild winters enable its survival in some regions. The larval stage is the most destructive phase, feeding voraciously on plant leaves and can cause severe defoliation. They can migrate in large numbers, devouring entire fields within a short period if left unchecked.

Working towards effective FAW management

Efficient monitoring, early detection, and appropriate management strategies are crucial for mitigating the impact of FAW infestations and protecting agricultural crops. To combat the menace of this destructive pest, CIMMYT, with support from the United States Agency for International Development (USAID), has been implementing research and extension on cultural control practices in Zimbabwe. One such initiative is the “Evaluating Agro-ecological Management Options for Fall Armyworm in Zimbabwe”. Since 2018, this project strives to address research gaps on FAW management and cultural control within sustainable agriculture systems. The focus of the research has been to explore climate-adapted push-pull systems and low-cost control options for smallholder farmers in Zimbabwe who are unable to access and use expensive chemical products.

Environment friendly practices are proving effective to combat FAW risks

To reduce the devastating effects of FAW, the project in Zimbabwe is exploring the integration of legumes into maize-based strip cropping systems as a first line of defense in the Manicaland and Mashonaland east provinces. By planting maize with different, leguminous crops such as cowpea, lablab and mucuna, farmers can disrupt the pests’ feeding patterns and reduce its population. Legumes release volatile compounds that repel FAW, reducing the risk of infestation. Strip cropping also enhances biodiversity, improves soil health and contributes to sustainable agricultural practices. Overall results show that FAW can be effectively managed in such systems and implemented by smallholder farmers. Research results also discovered that natural enemies such as ants are attracted by the legumes further contributing to the biological control of FAW.

Recently, the use of biopesticides such as Fawligen has gained traction as an alternative to fight against fall armyworm. Fawligen is a biocontrol agent that specifically targets the FAW larvae. Its application requires delicate attention – from proper storage to precise mixing and accurate application. Following recommended guidelines is essential to maximize its effectiveness and minimize potential risks to human health and the environment.

Impact in numbers

Since the inception of the project, close to 9,000 farmers participated in trainings and exposure activities and more than 4,007 farmers have adopted the practices on their own field with 1,453 hectares under improved management. Working along with extension officers from the Ministry of Lands, Agriculture, Water, Fisheries & Rural Resettlement, the project has established 15 farmer field schools as hubs of knowledge sharing, promoting several farming interventions including conservation agriculture practices (mulching, minimum tillage through ripping), timely planting, use of improved varieties, maintaining optimum plant population, and use of recommended fertilizers among others.

Addressing FAW requires a multi-faceted approach. The FAW project in Zimbabwe is proactive in tackling infestation by integrating intercropping trials with legumes, harnessing the application of biopesticides, and collaborative research. By adopting sustainable agricultural practices, sharing valuable knowledge, and providing farmers with effective tools and techniques, it is possible to mitigate the impact of FAW and protect agrifood systems.

Enhancing partnerships for agricultural development

Implementing partners of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) project, or MasAgro Africa, converged in Arusha, Tanzania, for the project’s first annual review and planning meeting. The event, which brought together 58 participants from 28 allied organizations coordinating and implementing activities as part of the flagship USAID-funded initiative, provided an opportunity to review progress towards targets set at the project launch in September 2022. During the event, partners also took time to collaboratively plan for stronger implementation in the project’s second year, while discussing challenges faced in the previous year and coming up with practical solutions for these. Similar planning meetings took place in Malawi and Zambia during the same month.

Speaking during the meeting’s opening session, USAID Tanzania Mission Feed the Future Coordinator Melanie Edwards expressed excitement about the achievements of in-country partners in the past year. “The Tanzania component of the project was performing very well,” she said, “and it was exciting to see the proposals coming, meaning that the number of partners was expanding.” Edwards noted that there is still a lot more to be done by the AID-I project and a call for new partner proposals was going to be issued soon to augment ongoing work. She also emphasized the importance of expanding the number of partners and was eager to see planned activities for the second year of the project.

Speaking on behalf of the Government of Tanzania—a key partner in the AID-I initiative—Abel Mtembenji outlined the government’s priorities: increasing productivity, creating decent jobs, enhancing extension services, improving resilience for food security, and expanding market and credit access. Mtembenji was pleased that AID-I interventions aligned with these and encouraged stakeholders to coordinate their efforts with the Tanzanian government to enhance the sustainability of project activities. He further encouraged stakeholders to notify the government of their initiatives to foster collaboration during implementation. Mtembenji recognized the support from USAID, through CIMMYT and thanked all partners for their participation and contribution to agricultural development in Tanzania.

Showcasing early successes

The AID-I initiative provides targeted assistance to up to three million African smallholder farmers by improving soil health and fertilizer management; strengthening local seed systems; connecting to financial products and services; and delivering extension and advisory services. An update presentation made by SAS Program Manager Grace Mwai revealed that through its 42 partners across Malawi, Tanzania, and Zambia, AID-I had in the past 12 months set up 125 mega-demonstrations for the 2022-2023 season. Forty-two of these were managed by farmer groups themselves, with 60% managed by women.

Across all three project countries, AID-I also reached approximately 5.3 million farmers with various agronomic advisory messages through radio and television, 160,000 listeners through interactive voice response (IVR) messages. Over 9,000 farmers were linked to inputs and outputs markets, of which 40% were women. Mwai added that the project had also conducted 5,143 seed company demonstrations—of which 2,400 took place in Tanzania—and had harvested and processed 13,000 metric tons of certified maize and legume seed, which was expected to directly benefit around one million smallholder farmers across the hub.

To highlight achievements from the first project year, partners showcased their products through posters and display items like seed packets during a structured session based on the World Café method. This activity allowed participants to interact and ask questions about various innovations being scaled under AID-I. More than ten partners displayed their products, and all participants at the meeting were given 15 minutes to visit other tables and share how many tons of seed they had produced and how many farmers they could reach during the season.

On the second day of the meeting, partners organized themselves into three small groups based on the three AID-I pillars—Seed Systems, Agriculture Advisories, and Market Linkages—to discuss forthcoming activities and what they hoped to do better in the coming season. The meeting concluded with discussions on issues including financial reporting, establishing and nurturing collaborations, and leveraging technology for improved project outcomes. During his closing remarks, Legume and Seed Systems Specialist under AID-I, Peter Setimela, emphasized the importance of timely proposal submission for the second year.

Afriseed: How improved legume seed can help transform Zambia’s agrifood systems

Written by mcallejas on . Posted in Blogs.

In Zambia, smallholder farmers obtain their seed from a variety of sources. Over 75 percent of farmers in Zambia have adopted certified maize seed and about 30 percent in southern Africa, overall. The private sector has been instrumental in creating demand for certified and timely delivery of seed to remote areas, and the Government of Zambia’s Farmer Input Support Programme (FISP) has largely contributed to better accessibility to certified seed for farmers. In 2022–2023, of the three million registered smallholder farmers in Zambia, more than one million accessed certified seed through FISP.

Afriseed is a seed company in Zambia that has been gaining ground in local seed markets. It has emerged as a catalyst for helping smallholder farmers transition to new, high-yielding legume varieties. Afriseed provides solutions to help smallholders increase their agricultural productivity with improved seed varieties of cereals and legumes and assist them with technology transfer. The company aims to increase the food security and incomes of Zambia’s smallholder farming community, which accounts for 90 percent of agricultural output in the country. During the 2022–2023 farming season, a critical turning point was reached when Afriseed became a partner in the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, a two-year project under CIMMYT, with the aim of scaling-up production of certified seed varieties of soybean and common bean.

Under the partnership, Afriseed promotes the cultivation of improved legume seed through a smallholder farmer seed multiplication approach. By engaging with practicing smallholder farmers and signing grower contracts, basic seeds are multiplied into certified seed for soybean and common bean. Certified seed is a known variety produced under strict seed certification standards to support varietal purity. In collaboration with the Seed Control and Certification Institute (SCCI), the country’s national seed authority, contracted farmers received training on climate-smart agricultural techniques and seed production guidelines. Through extension services to seed growers, smallholder farmers can adhere to the seed production guidelines set out in the National Seed Act to ensure the quality of certified seed produced.

Afriseed has invested more than USD 335,000 toward supporting the production, aggregation, and processing of 317 t of certified climate-smart legume seeds—265 metric tonnes (MT) for soybean and 52 MT for common bean. Data have shown that the seeds were aggregated from 313 smallholder seed growers, 40 percent of whom were women, in Zambia’s Eastern Muchinga, Copperbelt and the Northern provinces. Seed aggregation improves access to quality seed varieties, increases crop yields and incomes, enhances integration into value chains, and creates market links for smallholder farmers.

Notable progress has been made with the contracted farmers, who have applied improved crop management practices and technologies on more than 600 ha of land to produce the seed. With this encouraging progress, Afriseed intends to scale up its last-mile seed distribution strategy to reach and directly help an estimated 35,000 underserved rural smallholder farming households with improved legume seeds in the 2023–2024 cropping season.

AID-I is one of the ways in which Feed the Future, the U.S. Government’s global food security and hunger initiative led by USAID, is taking immediate action to help cushion the blow of high fuel and fertilizer prices on farmers. One of the project’s initial actions is to strengthen local seed systems so that agribusinesses can reach smallholder farmers with a diversity of improved seeds varieties, including climate-resilient and more nutritious varieties for maize and legumes.

Transforming rural agriculture with improved seed and mechanization

More than 1,300 smallholder farmers, across the Mwenezi and Masvingo districts of Zimbabwe, braved the hot morning sun to attend the fourth edition of the seed and mechanization fair organized by CIMMYT and partners in early October 2023. The event, themed “Harnessing improved seed and mechanization for climate resilience,” saw these farmers from all walks of life—first timers to past attendees—eager to participate, learn and explore the innovations on display.

Evolving over time, the seed and mechanization fair has continued to serve as a strategic platform to connect local farmers with private sector companies while enhancing the uptake of drought-tolerant maize varieties and scale-appropriate machinery. “Since 2020, CIMMYT-driven seed fairs have encouraged smallholder farmers in semi-arid areas, to grow the right seed at the right time to avoid any shortcomings due to unpredictable of weather patterns,” said Christian Thierfelder, principal cropping systems agronomist at CIMMYT.

Fast approaching farming season

El Niño continues to pose a threat to farmers especially in semi-arid areas such as in Mwenezi district situated in southern Zimbabwe and Masvingo district in south-eastern Zimbabwe which are drought prone areas characterized by high temperatures, rainfall deficit, among other challenges. Through the seed fairs, CIMMYT, a consortium member of the World Food Program projects, R4 Rural Resilience and the Zambuko Livelihoods Initiatives supported by the Swiss Agency for Development and Cooperation (SDC) and USAID, has been at the forefront, advocating for and inspiring local farmers to buy and use seed varieties suitable for their environment, while encouraging farming as a business. In addition, the regional project Ukama/Ustawi Diversification in East and Southern Africa joined efforts to support farmers in income diversification from pure cereal-based systems to more diversified cereal-legume and mechanized farming systems.

“I believe this is the right function at the right time as we prepare for the next farming season. From this event, we anticipate that farmers will say, ‘Yes we have received new technology, yes we have knowledge on new varieties, yes we have information about the weather forecast’. We now have confidence that farmers are well-equipped and ready for the season to achieve the Zimbabwe Vision 2030,” said Isaac Mutambara, district development coordinator from Mwenezi.

Building resilience with drought-tolerant varieties

Amid climate change, equipping farmers with climate-smart knowledge and the right seed varieties has been central to the seed fairs. Working hand in hand with the government, CIMMYT has been breeding drought tolerant, orange maize with high nutritional value. “We encourage the growing and consumption of crops with nutritional value for household food security. Furthermore, we have different varieties of orange maize which are drought-tolerant,” said Thokozile Ndhlela, maize line development breeder. In addition, CIMMYT as part of HarvestPlus, has been encouraging the growing and consumption of nutritious NUA45 beans which are high in iron and zinc.

Mechanizing agriculture

The joint participation of the USAID funded ‘Feed the Future Zimbabwe Mechanization and Extension activity’, helped to emphasize the importance of transforming smallholder agriculture through scale-appropriate equipment. At the event, machinery manufacturers such as Prochoice, Kurima and Mahindra showcased cutting-edge machinery, designed to ease farming operations. These companies showed live demonstrations of two-wheel tractors, basin diggers, multiple crop threshers amongst others, effectively emphasizing the benefits of scale-appropriate mechanization. The innovations on display demonstrated the unwavering dedication of the private sector towards supporting farmers and driving agricultural innovation. “It has been a truly exciting opportunity operating the peanut sheller, while appreciating the different machinery in live action. I will consider buying this machine as it reduces the added burden of shelling and processing,” said Lungiwe Nyathi, a local farmer from Mwenezi.

Partnerships for growth

Various seed companies, including AgriSeeds, SeedCo, Farm and City, Super Fert, National Tested Seeds, Intaba Trading, Sesame for Life and K2, marketed appropriate seed varieties that ensure bumper harvests. Sales of seed, fertilizer and other inputs were high, with the total value of sales reaching US6,450. Vouchers were distributed to farmers who made high cash purchases of seeds. “I bought 45kgs of seed which I believe is a great start, and I am happy that I do not have to pay extra money for transporting the seed to my home,” said Martha Chiwawo, a farmer from ward 16 in Masvingo.

The fairs would not be complete without CIMMYT partners. While Zambuko Livelihoods Initiative shared their expertise in the district, SNV has been encouraging sustainable savings and lending schemes among farmers to purchase machinery while facilitating market access and reducing post-harvest losses. The World Food Programme (WFP) encouraged farmers to become resilient and self-sufficient through valuable knowledge and skills to improve their lives. In addition, the Mwenezi Development Training Centre (MDTC) focused on encouraging small livestock which are adaptable to the area. Additional partners Cesvi and Sesame for Life, who both operate in ward 6 of Mwenezi district, participated in the seed fairs for the first time. Both partners advance the production of high value crops—paprika and sesame—which have a ready export market and favorable prices for smallholder farmers. Government extension departments showed strong support while researchers from the Makoholi Research Station in Masvingo used the opportunity to talk to farmers about their research initiatives.

As the day came to an end, farmers were brimming with excitement and ready to embark on the season ahead with purchased, improved seed and a wealth of knowledge on innovative conservation agriculture practices. The event proved to be an invaluable opportunity for uniting farmers, government, seed companies, and partners in a shared mission to promote sustainable farming practices and ensure food security.

Strengthening seed systems with Zamseed

Maize is a vital crop in Zambia and Tanzania, both for farmers’ economic livelihoods and for delivering nutrients and sustenance to a large group of people. But maize is threatened by climate change, like more severe droughts, and from pests like fall army worm (FAW), which can completely devastate farmers’ fields.

Against this backdrop of looming threats, CIMMYT, as part of the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, is partnering with the Zambia Seed Company Limited (Zamseed) to distribute seeds that are drought tolerant and resistant to the ravages of FAW. And because maize is a staple of many people’s diets, CIMMYT and Zamseed are also developing and distributing maize varieties enhanced with vitamin A.

To uphold maize variety integrity, CIMMYT and Zamseed are engaged in the capacity building of quality assurance and quality control for local stakeholders.

CIMMYT’s engagement with Zamseed involves efforts to popularize high yielding, drought-tolerant, and vitamin enhanced maize varieties in Zambia and Tanzania. Some of these efforts include demonstrations of the new varieties, field days held at different stages of maize development, and deliberate engagement of women throughout the entire seed selection, planting and harvesting effort.

“Our partnership with Zamseed started in October 2022,” said Ir Essegbemon Akpo, a CIMMYT maize seed systems specialist. “It has been a fruitful collaboration, delivering significant outputs to thousands of farmers in Zambia and Tanzania.”

To date, Zamseed has held 300 and 500 demonstrations in Tanzania and Zambia, respectively. The company has held many field days at the demonstration sites to showcase drought tolerant and vitamin A enhanced maize to hundreds of small-scale farmers.

“We have witnessed many farmers who visited the demonstration activities who are excited to see the new high yielding and drought tolerant varieties,” said Amsal Tarekegne of Zamseed.

Seeded by funds from the AID-I project, Zamseed is producing 60kg of Early Generation Seed (EGS) of parents of a FAW-tolerant hybrid maize variety. The company plans to produce 200kg of this hybrid for commercialization and launch in 2024.

To ensure that seeds delivered to farmers are of the highest quality, CIMMYT is working with Zamseed to develop quality assurance and control frameworks, involving genotyping of selected seeds at various times during the seed multiplication and distribution process.

Zamseed has been servicing the requirements of farmers in the sub-Sahara region since 1980, focusing on products that will enhance the profitability of the small-scale farmer and ensure household food security.

Exposing the potential of agricultural mechanization in India and Bangladesh

Written by Nur-A-Mahajabin Khan on . Posted in Blogs.

As geographical neighbors, Bangladesh and India share many characteristics in terms of land, weather, and food production. Because of these similarities, the Feed the Future Cereal Systems Initiative for South Asia-Mechanization Extension Activity (CSISA-MEA) organized a series of exposure visits to India for Bangladeshi farmers and other agricultural stakeholders to establish market linkages, provide access to financial and technical advice.

The CSISA-MEA, funded by the United States Agency for International Development (USAID) works to increase the usage of agricultural machinery to benefit farmers by increasing their productivity and efficiency. The Activity works with several stakeholders, including agriculture-based light engineering (ABLE) enterprises, dealers, and machinery solution providers (MSPs).

Over the course of the activity, a significant lesson learned is that both groups, the hosting party and the visiting party, benefit from exposure visits.

CSISA-MEA organized two international exposure visits to India in July 2023. A total of 34 participants in two cohorts visited India, 18 workers from Faridpur and Cox’s Bazar, and 16 from Bogura and Jashore.

CSISA-MEA arranged the visits with the objective to familiarize Bangladesh ABLE enterprises with modern agri-machinery manufacturing and improve their working practices. The visits covered factories, ABLE workshops and foundries in Punjab, including Amargarh, Bamala, and Ludhiana, areas where India’s agriculture mechanization is most notable, and incorporated public and private sector companies, and academia including LANDFORCE, M/S Dasmesh Mechanical Works, Panesar Agriculture Works Pvt. Ltd., Sokhi Manufacturing Ltd., the Borlaug Institute for South Asia, and National Agro Industry.

Learnings from the exposure visit

The exposure visits have emphasized the importance of systematic line production for machinery and spare parts manufacturing to ensure efficiency and consistency in output. Quality control has been highlighted as a non-negotiable aspect, and the significance of delivering reliable and high-quality products. Using natural light and ventilation systems showcased the potential for environmentally friendly production facilities.

The visits also highlighted how maintaining proper occupational health and safety measures ensures the well-being of the workforce along with a gender inclusive environment in the agri-machinery factories. The factories have a significant female workforce, an eye-opening sight for the ABLE owners of Bangladesh.

These exposure visits have helped equip ABLE owners with invaluable insights and strategies for success in their agricultural machinery businesses, including building connections among themselves, such as that between two ABLEs from Jashore, Bangladesh to facilitate the production and supply of the fodder chopper–demonstrating the potential for cooperation to expand market reach.

Reflections from the visits

The trip to meet their Indian counterparts provided CSISA–MEA ABLE owners with invaluable insights and knowledge, with their unanimous feedback reflecting the profound impact of the visits, which they deemed truly eye-opening. Encouragingly, since their return, each ABLE enterprise has prepared action plans, taking proactive steps to implement the new techniques and business strategies they gained during their visit.

“I can’t express how thrilled I am to have unlocked the secrets behind the exceptional quality of Indian machines and spare parts. It’s not just a technical upgrade, it’s a commitment to quality products,” said Md. Ashraf Hosen, owner of M/S Ashraf Machinery & Akmol Engineering Workshop.

Another visitor, Md. Iqbal Hosen, proprietor of Titas Moulding & Engineering Works, said, “I found discovering new innovations very exciting, especially the core-making process, the mechanical mold-making process to reduce production costs, appropriate charge calculation techniques and induction furnaces. I’m determined to apply these things in my foundry, to improve the quality of the products and reduce production costs.”

Sarkar Agro-Engineering & Multiple Works in Bangladesh has displayed a commitment to implementing the key takeaways of the exposure visit to India. The owners have ensured natural light and ventilation in their production facilities, creating a more conducive and eco-friendlier working environment for staff. They have also installed a customized lathe machine, painting every part of a machine before assembling it, and manufacturing mini tractors, all because of their exposure visit.

CSISA–MEA staff have also taken something from the trips, including feedback to include demonstrations of forging machines in future visits to further extend the workforce’s technical knowledge. There are plans to visit local spare parts markets during the next expedition to provide participants with a broader understanding of market dynamics, while visits to solar power and battery-operated machinery companies would provide an opportunity to witness sustainable technologies in action.

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

Harnessing Change was the theme of the 2023 Borlaug Dialogue, an annual summit of international thought leaders, development specialists, researchers, farmers, and practitioners, designed to promote global food systems transformation and food security, and is organized by the World Food Prize Foundation.

This iteration of the Borlaug Dialogue, held in Des Moines, Iowa, October 24-26, 2023, was the site of the inauguration of a collaboration between CIMMYT and the Gorongosa Restoration Project to improve climate resilience, food security and nutrition in Mozambique’s Gorongosa National Park.

“These kinds of collaborations exemplify what the Borlaug Dialogue is all about,” said CIMMYT Director General Bram Govaerts. “The annual event and the work of the World Food Prize Foundation year-round is dedicated to bringing people and organizations together to work better and smarter. CIMMYT is proud to be a part of it.”

CGIAR Centers based in the Americas host discussion on Latin America’s food security challenges and opportunities

CIMMYT, the International Potato Center (CIP), the Alliance of Bioversity International and the International Center for Tropical Agriculture, and International Food Policy Research Institute (IFPRI) co-organized the side event Maximizing Latin America and the Caribbean’s Contributions to Global Agriculture and Biodiversity Solutions at Dialogue.

Govaerts moderated the panel discussion and the Q&A session that followed with members of the audience.

Panelists, including Elsa Murano, director of the Norman E. Borlaug Institute for International Agriculture & Development, Rob Bertram, chief scientist for the Bureau for Resilience and Food Security at the U.S. Agency for International Development (USAID), and María (pilu) Giraudo, honorary president of Argentina’s No Till Farmers Association, shared views on Latin America’s role in global agriculture from academic, development and farming offer academic insights, international cooperation recommendations and farmer perspectives.

CIMMYT and USAID co-host panel focused on AID-I’s impact at the Borlaug Dialogue

CIMMYT and USAID hosted an event at the Dialogue organized by the World Food Prize Foundation on October 25 focused on the Southern Africa Accelerated Innovation Delivery Initiative (AID-I).

The discussion labelled, Harnessing Innovation to Rapidly Respond to Crises, aimed to present AID-I’s innovative approach to addressing systemic weaknesses in agriculture by accelerating the market-based delivery of improved seeds, fertilizers, and critical information to farmers.

Dina Esposito, USAID’s Global Food Crisis coordinator and assistant to the Administrator for the Bureau for Resilience, Environment and Food Security, described how AID-I is “turning crisis into opportunity” by improving farmers’ resilience and profitability.

“We joined CIMMYT and went to Zambia, and the partnership was a glimmer in our eyes,” said Esposito, referring to a recent visit to a model farm with AID-I partners.

Reporting progress in Zambia, Malawi and Tanzania, Kevin Kabunda, CIMMYT’S AID-I chief of party in southern Africa, noted that the private sector had produced 13,000 tons of maize in the first year.

“The extended or increased potential for every farmer who uses fall armyworm-tolerant varieties translates to US$100 dollars,” said Kabunda who estimated AID-I reached 1.3 million farmers in its first year generating an aggregated value of at least US$65 million dollars.

In addition, Mtieyedou (Abdou) Konlambigue, AID-I chief of party in the Great Lakes Region, pointed out that the project has given access to new bean varieties and fertilizer recommendations to over 500,000 farmers in Rwanda, Burundi and the Democratic Republic of the Congo.

Farmers take the stage

Two champion farmers, María (pilu) Giraudo and Guillermo Bretón joined CIMMYT’s Director General, Bram Govaerts, and CGIAR Board Chair, Lindiwe Majele Sibanda, during a main stage session of the Borlaug Dialogue organized by the World Food Prize Foundation on Tuesday, October 24.

The event, MasAgro Taking it to the Farmer, reported on progress achieved and milestones reached by one of CIMMYT’s flagship projects, Crops for Mexico (MasAgro), which began 14 years ago and earned Govaerts the 2014 Norman E. Borlaug Award for Field Research and Application endowed by The Rockefeller Foundation.

Giraudo, an Argentinian farmer who co-founded the Rural Women Network and serves as honorary president of Argentina’s no till farmer association Aapersid, said that the best way to acknowledge MasAgro’s work is to seize the opportunity to offer women farmers the possibility of having full access to science and technology.

Bretón, a farmer from Mexico’s state of Tlaxcala, described MasAgro as a disruptive way of understanding agriculture. “Investing in our soils is better than investing in a one-cycle crop,” he said.

CGIAR Board Chair Lindiwe Majele Sibanda was enthusiastic about the project’s trajectory and proud of its evolution into CIMMYT’s ongoing efforts, including adapting MasAgro to southern Africa.

Sibanda expressed her excitement about MasAgro-inspired activities in Africa and praised the diversified seed systems that today include dryland crops sold in smaller seed bags by young entrepreneurs who are taking up businesses in villages without having to go to urban centers.

Govaerts moderated the event and thanked Dina Esposito, and U.S. Special Envoy for Global Food Security, Cary Fowler, for facilitating the establishment of MasAgro programs in southern Africa.

Early maturity products popular among farmers in Kenya

Written by mcallejas on . Posted in Publications.

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.

This article is adapted from Market Intelligence Brief 5: Maize Farmers Acquire Early-Maturity Seed Across Production Environments – the fifth paper in the ongoing peer-reviewed series published inMarket Intelligence Briefs.

*About Market Intelligence Briefs

The CGIAR Initiative on Market Intelligence (‘Market Intelligence’ for brevity) represents a new effort to engage social scientists, crop-breeding teams, and others to work together toward the design and implementation of a demand-led breeding approach. In 2022, the Market Intelligence Brief (MIB) series was created as a valuable communication tool to support informed decision making by crop breeders, seed-system specialists, and donors on future priorities and investments by CGIAR, NARS, the private sector, and non-governmental organizations (NGOs).

Evaluating Agro-ecological Management Options for Fall Armyworm in Zimbabwe

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

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.

Scaling up health diet seed kits in Zanzibar

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

Many people on the islands of Zanzibar face food insecurity and nutritional challenges. The Southern Africa Accelerated Innovation Delivery Initiative (AID-I) MasAgro Africa Rapid Delivery Hub, implemented by CIMMYT, has partnered with the World Vegetable Center (WorldVeg) to directly distribute health diet seed kits to vulnerable households, while prioritizing vulnerable groups such as pregnant and lactating mothers and children under five.

The kits contain a diverse selection of nutrient-rich vegetables specifically chosen for their high nutritional value, ensuring optimal health and development.

To date, the partnership has reached an impressive number of households in Zanzibar. Over 1,350 health diet seed kits have been distributed, or one seed kit per household, benefiting approximately 4,050 individuals (considering at least three people per household). These numbers showcase the tangible impact AID-I has made in addressing the root causes of malnutrition and hidden hunger, providing a sustainable pathway towards improved health and a brighter future for Zanzibar.

The World Vegetable Center (WorldVeg) conducts research, builds networks, and carries out training and promotion activities to raise awareness of the role of vegetables for improved health and global poverty alleviation.

“This initiative holds tremendous promise in fostering long-term improvements in food security, nutrition, and overall well-being for the communities in Zanzibar and shows the power of collaboration,” said Kevin Kabunda, CIMMYT lead for the AID-I project.

Seed variety encourages improved nutrition

A key strength of the seed kits lies in their diversity. Each kit comprises a range of seeds for various crops, including legumes and nutrient-rich vegetables. This includes amaranth consumed as leafy and grain, African eggplant, Ethiopian mustard, African nightshade, and cowpea. The combination of these diverse crops ensures a more resilient and nutritious food supply, essential to combating malnutrition and fostering agricultural sustainability in the islands.

The seed kits are tailored to suit the local agroecological conditions, considering the specific needs and preferences of farmers in Zanzibar. This localization approach enhances the adoption of the kits and maximizes their potential impact on food security and dietary diversity.

“The partnership between WorldVeg and CIMMYT has been invaluable in driving the success of this activity in Zanzibar,” said Jeremiah Sigalla, WorldVeg technical lead for the AID-I project in Zanzibar. “By providing farmers with these healthy diet seed kits, we aim to promote the cultivation of diverse crops that are essential for a balanced and nutritious diet and its attendant benefits, particularly among vulnerable communities.”

By raising awareness about the significant benefits of incorporating diverse vegetables into daily diets, the partnership has inspired and encouraged the community to fully embrace the intervention. This collaboration between CIMMYT and WorldVeg is a testament to the potential of collective action, highlighting sustainable solutions and community empowerment as essential elements in combating malnutrition and enhancing overall well-being in Zanzibar.
