CIMMYT’s work in Africa helps farmers access new maize and wheat systems-based technologies, information and markets, raising incomes and enhancing crop resilience to drought and climate change. CIMMYT sets priorities in consultation with ministries of agriculture, seed companies, farming communities and other stakeholders in the maize and wheat value chains. Our activities in Africa are wide ranging and include: breeding maize for drought tolerance and low-fertility soils, and for resistance to insect pests, foliar diseases and parasitic weeds; sustainably intensifying production in maize- and wheat-based systems; and investigating opportunities to reduce micronutrient and protein malnutrition among women and young children.

Soybean rust threatens soybean production in Malawi and Zambia

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.

Livestock Production Systems in Zimbabwe (LIPS-Zim)

The livestock sub-sector is one of the most important arms of the agricultural sector, contributing to the livelihoods of 70% of Zimbabwe’s rural population. Sustainable livestock production depends on the maintenance of healthy and productive animals which requires paying particular attention to the problems of both endemic and introduced animal diseases and zoonotic. Climate relevant livestock production practices such as fodder management and conservation, water harvesting, and manure management have been identified as solutions to increasing livestock productivity.

The Livestock Production Systems in Zimbabwe (LIPS-Zim) project, funded by the European Union (EU) focuses on increasing agricultural productivity in Zimbabwe’s semi-arid, agro-ecological regions IV and V. Led by the International Livestock Research Institute (ILRI) and in partnership with CIMMYT, the French Agricultural Research Center for International Development (Cirad) and the University of Zimbabwe (UZ), LIPS-Zim is working in 10 districts of Zimbabwe, i.e. Matabeleland South Province (Beitbridge and Gwanda districts), the parched Matabeleland North Province (Binga, Hwange and Nkayi districts), Midlands (Gokwe North district), Masvingo (Chiredzi and Zaka districts), Manicaland (Buhera district) and Mashonaland East (Mutoko district). LIPS-Zim is conducting research that seeks to increase livestock feed productivity and well as reducing diseases and mortality of livestock.

Main objectives

Core to the project is to increase the adoption of climate-relevant innovations (e.g feeding) in livestock-based production systems and improve the surveillance and control of livestock diseases. CIMMYT’s main thrust in this project is based on the recognition that at least 50% of the arable land area in semi-arid region IV and V of Zimbabwe is still put to maize despite extension recommendations for farmers to grow the more resilient small grains in those regions. Given the above, and to address their food and feed needs, farmers in those regions need drought-tolerant and nutritious maize varieties that are resilient in those dry environments. CIMMYT’s work is thus focusing on testing the feed value of these nutritious and drought tolerant maize varieties when intercropped with various legumes such as mucuna, cowpea, lab-lab and pigeonpea. CIMMYT is also testing the later, along with climate smart production techniques such as conservation agriculture and water harvesting practices.

Tackling fall armyworm with sustainable control practices

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.

Examining how insects spread toxic fungi

According to the World Health Organization (WHO), 10% of the global population suffers from food poisoning each year. Aflatoxins, the main contributor to food poisoning around the world, contaminate cereals and nuts and humans, especially vulnerable groups like the young, elderly, or immune-compromised, and animals are susceptible to their toxic and potentially carcinogenic effects.

Fungi contamination occurs all along the production cycle, during and after harvest, so the mitigation of the mycotoxins challenge requires the use of an integrated approach, including the selection of farmer-preferred tolerant varieties, implementing good agricultural practices such as crop rotation or nitrogen management, reducing crop stress, managing pests and diseases, biological control of mycotoxigenic strains, and good post-harvest practices.

Monitoring of mycotoxins in food crops is important to identify places and sources of infestations as well as implementing effective agricultural practices and other corrective measures that can prevent outbreaks.

A bug problem

Insects can directly or indirectly contribute to the spread of fungi and the subsequent production of mycotoxins. Many insects associated with maize plants before and after harvest act as a vector by carrying fungal spores from one location to another.

International collaboration is key to managing the risks associated with the spread of invasive pests and preventing crop damage caused by the newly introduced pests. CIMMYT, through CGIAR’s Plant Health initiative, partners with the Center for Grain and Animal Health Research of the US Department of Agriculture (USDA) and Kansas State University are investigating the microbes associated with the maize weevil and the larger grain borer.

The experiment consisted of trapping insects in three different habitats, a prairie near CIMMYT facilities in El Batán, Texcoco, Mexico, a maize field, and a maize store at CIMMYT’s experimental station at El Batán, using Lindgren funnel traps and pheromones lures.

Preliminary results of this study were presented by Hannah Quellhorst from the Department of Entomology at Kansas State University during an online seminar hosted by CIMMYT.

The collected insect samples were cultured in agar to identify the microbial community associated with them. Two invasive pests, the larger grain bore and the maize weevil, a potent carcinogenic mycotoxin was identified and associated with the larger grain borer and the maize weevil.

The larger grain borer is an invasive pest, which can cause extensive damage and even bore through packaging materials, including plastics. It is native to Mexico and Central America but was introduced in Africa and has spread to tropical and subtropical regions around the world. Together with the maize weevil, post-harvest losses of up to 60% have been recorded in Mexico from these pests.

“With climate change and global warming, there are risks of these pests shifting their habitats to areas where they are not currently present like sub-Saharan Africa and North Africa,” said Quelhorst. “However, the monitoring of the movement of these pests at an international level is lacking and the microbial communities moving with these post-harvest insects are not well investigated.”

New wheat varieties lauded for mitigating rust disease, increasing yield in Ethiopia

CIMMYT’s development and release of six new wheat varieties in Ethiopia, aimed at combating rust diseases and increasing yields, underscore its pivotal role in advancing agricultural self-sufficiency and productivity in the country. These varieties, covering the majority of Ethiopia’s wheat cultivation area, highlight CIMMYT’s significant contribution to enhancing food security and agricultural resilience.

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.

Understanding and Enhancing Adoption of Conservation Agriculture in Smallholder Farming Systems of southern Africa (ACASA)

Conservation agriculture (CA) has increasingly been promoted in southern Africa to address low agricultural productivity, food insecurity, and land degradation. Despite significant experimental evidence on the agronomic and economic benefits and the large scaling-up investments by donors and national governments, the adoption rates of CA practices among smallholder farmers are low and slow.

With funding from the Norwegian Agency for Development Cooperation (NORAD) and implemented by the International Institute of Tropical Agriculture (IITA) and CIMMYT, ACASA strives to understand “why previous efforts and investments to scale CA technologies and practices in southern Africa have not led to widespread adoption.” It is a three-year project implemented in Malawi, Zambia, and Zimbabwe, where CA is part of national policy.

Since 2021, the project has undertaken extensive surveys aimed to understand incentives, drivers, and barriers of CA adoption across the three countries (Malawi, Zambia, and Zimbabwe) typifying much of the southern Africa smallholder systems. The aim of the project is to consolidate the lessons learned so far and provide a pathway to scaling and foster the next generation of social, crop, agronomic and climate research; to mainstream CA enabled by fundamental paradigm shifts in farming practices, markets, and social institutions for sustainable intensification of smallholder farming systems of southern Africa.

Project objectives include –

  • Understanding the contexts of smallholder farmer in southern Africa to identify the drivers and barriers preventing adoption of CA practices, including biophysical, socio-economic, institutional and policy constraints
  • Identifying labor-efficient mechanization options for smallholder farmers
  • Identifying opportunities and tools for better targeting of appropriate CA practices and options across heterogenous agroecologies and farm types, and
  • Identifying approaches and strategies for inclusive scaling of CA practices (policy, institutional and value chain entry points and pathways to promote and scale CA)

 

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

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.

Tela maize will boost food sufficiency, create wealth in Nigeria – Stakeholders

Every drop of water matters: Leading global research institutes ally to aid farmers in dry and saline ecosystems

CIMMYT and ICBA sign a memorandum of understanding. (Photo: ICBA)

Dubai/Mexico City, 10 January 2024 – An award-winning not-for-profit agricultural research center recognized for its work on sustainable agriculture in the Middle East and North Africa is joining forces with the global organization whose breeding research has contributed to half the maize and wheat varieties grown in low- and middle-income countries.

The International Center for Biosaline Agriculture (ICBA) and CIMMYT have signed an agreement to jointly advance the ecological and sustainable intensification of cereal and legume cropping systems in semi-arid and dryland areas.

“Farmers in such settings confront enormous risks and variable conditions and often struggle to eke out a livelihood, but they still comprise a critical part of the global food system and their importance and challenges are mounting under climate change,” said Bram Govaerts, director general of CIMMYT. “ICBA brings enormously valuable expertise and partnerships to efforts that will help them.”

The specifics of the two centers’ joint work are yet to be defined but will cover soil health, salinity management approaches, crop productivity and breeding, gender-transformative capacity development, and finding markets for underutilized crops, among other vital topics.

Established in 1999 and headquartered in the United Arab Emirates (UAE), ICBA conducts research and development to increase agricultural productivity, improve food security and nutrition, and enhance the livelihoods of rural farming communities in marginal areas. The center has extensive experience in developing solutions to the problems of salinity, water scarcity and drought, and maintains one of the world’s largest collections of germplasm of drought-, heat- and salt-tolerant plant species.

“We are excited about the synergies our partnership with CIMMYT will create. It will focus on a range of areas, but the priority will be given to developing breeding and cropping system innovations to improve farmers’ food security and nutrition, while enhancing water security and environmental sustainability, and creating jobs and livelihoods in different parts of the world,” said Tarifa Alzaabi, director general of ICBA.

Based in Mexico but with projects in over 80 countries and offices throughout Africa, Asia and Latin America, CIMMYT operates a global seed distribution network that provides 80% of the world’s breeding lines for maize and wheat, including many that offer superior yields and resilience in dry conditions and in the presence of crop diseases and pests.

The center is also conducting breeding and seed system development for dryland crops such as sorghum, millet, groundnut, cowpea, and beans, known for their climate resilience and importance as foods and sources of income for smallholder farm households and their communities.

With global and local partners, CIMMYT is also refining and spreading a suite of resource-conserving, climate-smart innovations for highly diverse maize- and wheat-based cropping systems, including more precise and efficient use of water and fertilizer, as well as conservation agriculture, which blends reduced or zero-tillage, use of crop residues or mulches as soil covers, and more diverse intercrops and rotations.

As part of the new agreement, the centers will also explore research collaborations with universities and research institutions in the UAE to develop and test maize varieties that are suitable for the UAE’s climate and soil conditions, as well as organizing training programs and workshops for farmers, extension workers, and other stakeholders in the UAE to build their capacity in maize production and management.

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.

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.

Combatting maize lethal necrosis in Zimbabwe

Maize is a staple crop in Zimbabwe, playing a vital role in the country’s agricultural landscape as food for its own people and an export good. However, behind every successful maize harvest lies the quality of seed and resistance to diseases and stresses.

Amidst the multitude of diseases that threaten maize crops, one adversary is maize lethal necrosis (MLN). Though not native to Zimbabwe, it is crucial to remain prepared for its potential impact on food security.

What is maize lethal necrosis?

MLN is a viral disease, caused by a combination of two virus diseases. The disease emerged in Kenya in 2011 and quickly spread to other countries in eastern Africa. The introduction of MLN to Africa was likely affected by the movement of infected seed and insect vectors. MLN has had a severe impact on regional maize production, leading to yield losses of up to 90%.

Recognizing the need to equip seasoned practitioners with the knowledge and skills to effectively diagnose and manage MLN, CIMMYT organized a comprehensive training on MLN diagnosis and management, targeting 25 representatives from Zimbabwe’s Plant Quarantine Services.

From students to experienced technicians, pathologists and plant health inspectors, this was an opportunity to refresh their knowledge base or an introduction to the important work of MLN mitigation. “This training for both advanced level practitioners and students is crucial not only for building competence on MLN but also to refresh minds to keep abreast and be prepared with approaches to tackle the disease once it is identified in the country,” said Nhamo Mudada, head of Plant Quarantine Services.

Expectations were diverse, ranging from sharpening understanding of key signs and symptoms to learning from country case examples currently ridden with the disease. With CIMMYT’s guidance, practitioners learned how to identify MLN infected plants, make accurate diagnoses, and implement management strategies to minimize losses.

“For over 10 years, these trainings have been important to raise awareness, keep local based practitioners up to speed, help them diagnose MLN, and make sure that they practice proper steps to tackle this disease,” said L.M Suresh, CIMMYT maize pathologist and head of the MLN screening facility in Kenya.

Identifying the specific MLN causing viral disease affecting a maize plant is the first step in combating MLN. Determining whether it is a biotic or abiotic disease is critical in establishing its cause and subsequent diagnosis. By implementing proper diagnostic techniques and understanding the fundamentals of good diagnosis, practitioners can bring representative samples to the lab and accurately identify MLN.

Tackling MLN in Zimbabwe

Initiated in 2015 at Mazowe as a joint initiative between the Government of Zimbabwe and CIMMYT, a modern quarantine facility was built to safely import maize breeding materials from eastern Africa to southern Africa and enable local institutions to proactively breed for resistance against MLN.

The MLN quarantine facility at the Plant Quarantine Institute is run by the Department of Research and Specialist Services (DRSS) and is mandated to screen maize varieties imported under strict quarantine conditions to ensure that they are MLN-free.

To date, CIMMYT and partners have released 22 MLN resistant and tolerant hybrids in eastern Africa. CIMMYT’s research and efforts to combat MLN have focused on a multidimensional approach, including breeding for resistant varieties, promoting integrated pest management strategies, strengthening seed systems, and enhancing the capacity of farmers and stakeholders.

“Support extended through valuable partnerships between CIMMYT, and the collaborations have played a pivotal role from surveillance to diagnostics and building capacity,” said Mudada.

Feedback and insights

Chief Plant Health Inspector for Export and Imports Biosecurity, Monica Mabika, expressed gratitude for the training. “It is always an honor when we have expert pathologists come through and provide a valuable refresher experience, strengthening our understanding on issues around biosecurity and learning what other countries are doing to articulate MLN,” she said.

Among the students was Audrey Dohwera from the University of Zimbabwe, who acknowledged the importance of the training. “I have been attached for 2 months under the pathology department, and I was eager to learn about MLN, how to detect signs and symptoms on maize, how to address it and be able to share with fellow farmers in my rural community,” she said.

With the knowledge gained from this training, practitioners are well equipped to face the challenges that MLN may present, ultimately safeguarding the country’s maize production status.
