Theme: Climate adaptation and mitigation

Climate change threatens to reduce global crop production, and poor people in tropical environments will be hit the hardest. More than 90% of CIMMYT’s work relates to climate change, helping farmers adapt to shocks while producing more food, and reduce emissions where possible. Innovations include new maize and wheat varieties that withstand drought, heat and pests; conservation agriculture; farming methods that save water and reduce the need for fertilizer; climate information services; and index-based insurance for farmers whose crops are damaged by bad weather. CIMMYT is an important contributor to the CGIAR Research Program on Climate Change, Agriculture and Food Security.

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.

Wheat blast spread globally under climate change modeled for the first time

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

Climate change poses a threat to yields and food security worldwide, with plant diseases as one of the main risks. An international team of researchers, surrounding professor Senthold Asseng from the Technical University of Munich (TUM), has now shown that further spread of the fungal disease wheat blast could reduce global wheat production by 13% until 2050. The result is dramatic for global food security.

With a global cultivation area of 222 million hectares and a harvest volume of 779 million tons, wheat is an essential food crop. Like all plant species, it is also struggling with diseases that are spreading more rapidly compared to a few years ago because of climate change. One of these is wheat blast. In warm and humid regions, the fungus magnaporthe oryzae has become a serious threat to wheat production since it was first observed in 1985. It initially spread from Brazil to neighboring countries. The first cases outside of South America occurred in Bangladesh in 2016 and in Zambia in 2018. Researchers from Germany, Mexico, Bangladesh, the United States, and Brazil have now modeled for the first time how wheat blast will spread in the future.

Regionally up to 75% of total wheat acreage affected

According to the researchers, South America, southern Africa, and Asia will be the regions most affected by the future spread of the disease. Up to 75% of the area under wheat cultivation in Africa and South America could be at risk in the future. According to the predictions, wheat blast will also continue to spread in countries that were previously only slightly impacted, including Argentina, Zambia, and Bangladesh. The fungus is also penetrating countries that were previously untouched. These include Uruguay, Central America, the southeastern US, East Africa, India, and eastern Australia. According to the model, the risk is low in Europe and East Asia—with the exception of Italy, southern France, Spain, and the warm and humid regions of southeast China. Conversely, where climate change leads to drier conditions with more frequent periods of heat above 35 °C, the risk of wheat blast may also decrease. However, in these cases, heat stress decreases the yield potential.

Dramatic yield losses call for adapted management

The affected regions are among the areas most severely impacted by the direct consequences of climate change. Food insecurity is already a significant challenge in these areas and the demand for wheat continues to rise, especially in urban areas. In many regions, farmers will have to switch to more robust crops to avoid crop failures and financial losses. In the midwest of Brazil, for example, wheat is increasingly being replaced by maize. Another important strategy against future yield losses is breeding resistant wheat varieties. CIMMYT in collaboration with NARs partners have released several wheat blast-resistant varieties which have been helpful in mitigating the effect of wheat blast. With the right sowing date, wheat blast-promoting conditions can be avoided during the ear emergence phase. Combined with other measures, this has proven to be successful. In more specific terms, this means avoiding early sowing in central Brazil and late sowing in Bangladesh.

First study on yield losses due to wheat blast

Previous studies on yield changes due to climate change mainly considered the direct effects of climate change such as rising temperatures, changing precipitation patterns, and increased CO2 emissions in the atmosphere. Studies on fungal diseases have so far ignored wheat blast. For their study, the researchers focused on the influence of wheat blast on production by combining a simulation model for wheat growth and yield with a newly developed wheat blast model. Environmental conditions such as the weather are thus included in the calculations, as is data on plant growth. In this way, the scientists are modeling the disease pressure in the particularly sensitive phase when the ear matures. The study focused on the influence of wheat blast on production. Other consequences of climate change could further reduce yields.

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.

Examining how insects spread toxic fungi

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

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.”

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.

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.

Delivering the best seeds to farmers in Zambia

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

To bring together farmers with seed distributors and other stakeholders, the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) Rapid Delivery Hub, or MasAgro Africa, held a seed fair with the theme ‘Promoting Access to Drought Tolerant Seed and Appropriate Scale Technologies,’ in Zambia’s Chongwe district. The objectives of the fair were to create a platform for farmers and input suppliers to engage before the onset of the planting season. Over 1,200 farmers attended the seed fair.

“The seed fair plays a critical role in linking farmers to seed companies and exposes them to appropriate technologies. The links created with agro-dealers and other suppliers ensure farmers gain access to sufficient volumes of appropriate multiple stress tolerant maize hybrids, legume seed and agricultural inputs locally. Access to drought tolerant seed and technology in the times of climate change is timely and critical to today’s farmers. This fair will help our farmers acquire inputs at their doorsteps, promoting food security,” said Kasuba, the district agriculture officer.

AID-I is also using these fairs to provide information on agronomic practices such as conservation agriculture, climate-smart agriculture and small mechanization options to support smallholders not only to learn but also enjoy the events through participation in fun quizzes. Farmers purchase seed and other inputs when they redeem vouchers provided by participating companies who develop the questions for farmers.

A farmer who redeemed a voucher said, “I came from Nyimba, because I heard that there is a seed fair here. What I found was very interesting, and I learned a lot. I saw a lot of seeds from different companies. I have also managed to win this pesticide by answering a question, and I am very happy about this project.”

These add-ons to the seed fair ensure farmers learn about climate-smart practices and how they can mitigate climate change effects and crop damage caused by pests by using drought and pest resistant varieties. Pests such as fall armyworm (FAW) are a major threat to smallholder farmers and their crops, as these can destroy crops and lead to a significant decrease in yields and income for the farmer.

Some of the outcomes and benefits for the private sector, and farmers alike include farmers to access different seed hybrids at one location, reduced costs of transportation for farmers who often travel long distances to get inputs. Zamseed, an AID-I partner, was able to promote 600 packs of their ZMS 451-medium and ZMS 721-late maturity seeds. SeedCo, another AID-I partner was able to support farmers with 500 seed packs of their medium maturity SC 303-ultra early, SC 555-early and 657-medium maturity maize seed varieties to farmers. Seed input suppliers noted that maize seed packed in smaller bags weighing 10 kgs and of medium maturity variety seed were the most sought-after and have now influenced how they can reach much larger numbers of smallholder farmers through this observation on improved packaging and demand.

In addition to Zamseed and SeedCo, AID-I partners who participated in the seed fair include the Ministry of Agriculture, CRS, Afriseed, Synergy, Animive Enterprises, Bayer, Amiran, Syngenta, Omnia Fertilizer, and Corteva.

CIMMYT-BISA-ICAR partnership brings huge benefits in South Asia

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

A climate resilient agriculture program for the state of Bihar, India, launched in 2019 by the Borlaug Institute for South Asia (BISA) and the state government, was operating in 190 villages and had by 2022 improved water, soil nutrient, energy, labor and time use efficiency by at least 20% with around 35% higher yields and a reduced environmental footprint, as well as helping rice-wheat farmers to diversify their production with crops such as maize, millet and mungbean, among others.

This is just one of the achievements cited in a recent 2023 end-of-year reflection involving members of the BISA Executive Committee in New Delhi, India, including Bram Govaerts, director general of CIMMYT and BISA, and Arun Kumar Joshi, managing director of BISA.

“BISA has achieved significant milestones and is progressing towards organizational goals,” said Joshi. “The long-standing and productive partnership with the Indian Council of Agricultural Research (ICAR) and agricultural councils of other countries in South Asia became more robust, as strategies that focused on building capacities and improving seed systems for the whole of South Asia were implemented.”

Established jointly by CIMMYT and ICAR in 2011, BISA is a non-profit international research institute dedicated to food, nutrition, livelihood security and environmental rehabilitation in South Asia, home to more than 300 million undernourished people. Its work harnesses the latest genetic, digital, resource management technologies, and research-for-development approaches.

BISA’s flagship projects benefit millions of farmers and include the Atlas of Climate Adaptation in South Asian Agriculture (ACASA), the testing of experimental wheat that carries grass genes associated with the inhibition of nitrification in the soil near crop roots, a climate resilient agriculture program for South Asia, and implementation of the CGIAR Fruit and Vegetables for Sustainable Healthy Diets (FRESH) initiative.

“Of the top 10 bread wheat varieties in India, 6 are derived from the ICAR-CIMMYT-BISA collaboration,” Joshi explained.

“BISA has grown tremendously in the last few years,” said Govaerts. “The diverse arena of projects shows the capabilities and potential that BISA holds today. The flagship programs are undoubtedly creating a huge impact and would contribute to solving tomorrow’s problems today.”

BISA has renewed and diversified its research projects each year, according to T.R. Sharma, deputy director general of Crops, ICAR. “BISA’s impact on genetic innovation in wheat through ICAR-CIMMYT-BISA collaboration is indeed praiseworthy,” he said. Govaerts also attended an interactive session with CIMMYT-BISA India staff, presenting an analysis of the CIMMYT 2030 strategy and encouraging everyone’s contributions towards the goals.

How CGIAR maize breeding is improving the world’s major staple crop for tropical regions

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

Maize production is surging due to its diversified end uses. While it is already the first staple cereal globally, it is expected to emerge as the world’s predominant crop for cultivation and trade in the coming decade. Globally, it serves primarily as animal feed, but it is also a vital food crop, particularly in sub-Saharan Africa, Latin America, and in some areas in Asia. 

Climate change is, however, altering the conditions for maize cultivation, especially in the rainfed, stress-prone tropics. Abiotic stresses like heat, drought, and floods, as well as biotic threats such as diseases and insect pests are becoming more frequent. These have a disproportionate impact on the resource-constrained smallholders who depend on maize for their food, income, and livelihoods. 

In a race against time, crop breeders are working to enhance maize’s resilience to the changing climates. Among others, CIMMYT and the International Institute of Tropical Agriculture (IITA), working within CGIAR’s Accelerated Breeding Initiative, are utilizing breeding innovations to develop climate-resilient and nutritionally enriched maize varieties needed by the most vulnerable farmers and consumers.  

Better processes

Improving maize yields in the rainfed, stress-prone tropics is challenging. Nevertheless, CGIAR’s efforts have significant impacts, as breeding programs embraced continuous improvement and enhanced efficiency over the years.  

To increase genetic gains, CIMMYT maize breeding program implemented a systematic continuous improvement plan. Sixty percent of CIMMYT’s maize lines in Eastern and Southern Africa (ESA) are now developed through technologies that speed up breeding cycle and improve selection intensity and accuracy; these include doubled haploid technology, high-throughput phenotyping, molecular marker-assisted forward breeding, and genomic selection. The breeding cycle time has been reduced from five or six years to only four years in most of the maize product profiles. Product advancement decisions now incorporate selection indexes, and specialized software aid in the selection of parental lines for new breeding starts. 

CIMMYT and IITA maize teams are working together to investigate several key traits in maize for discovery, validation, and deployment of molecular markers. CGIAR maize team developed a framework for implementing a stage-gate advancement process for marker-trait pipeline, which enables informed decision-making and data-driven advancements at multiple stages, from marker-trait discovery proposal to marker discovery, validation, and deployment. Consolidating research efforts and implementing this process is expected to increase efficiency and collaboration in maize breeding programs.

At the end of the breeding process, breeders must ensure the quality assurance and quality control (QA/QC) of the parental lines of the new varieties. Seed quality, which includes genetic purity, genetic identity, and verification of parentage – is critical in maize breeding and commercial seed production.  

CIMMYT has worked to enhance the capacity of NARES and seed company partners in Eastern and South Africa (ESA), Asia, and Latin America, in utilizing molecular markers for QA/QC in breeding and commercial seed production. This has resulted in more reliable and accurate outcomes. In addition, webinars and user-friendly software have boosted results for NARES maize breeders, regulatory agencies, and seed companies. These combined efforts mean a dependable, cost-effective, and efficient QA/QC system for the maize seed value chain in the Global South. 

Better tools 

With traditional means, obtaining a genetically homozygous or true-to-type maize line requires six to eight generations of inbreeding, and thus, more than ten years for developing a new hybrid. The technique of doubled haploid (DH), which enables derivation of 100% genetically homozygous lines in just two generations, is now integral to modern maize breeding. CIMMYT has pioneered the development of tropical maize DH technology, by developing and disseminating tropicalized haploid inducers, establishing centralized DH facilities in Mexico, Kenya and India, and providing DH development service to partners.  

Regional on-farm trials (ROFTs) is a crucial step in maximizing the impact of breeding investments. ROFTs help scientists understand performance of the pipeline hybrids under diverse farmers’ management conditions, besides environment, soil variability, etc. 

In ESA, ROFT networks for maize are expanded significantly over the last few years, from 20-30 sites per product profile to up to 300 sites, encompassing a wide range of smallholder farming practices. The experimental design was simplified to use less germplasm entries to be tested per farm, making it easier for the farmers to participate in the network, while improving data quality. Collaboration with NARES, seed companies, NGOs, and development partners was significantly stepped up to capture the social diversity within the target market segments. Gender inclusion was prioritized.

Strengthening the capacity of NARES and SMEs to systematically access and utilize improved maize germplasm is critical for increasing genetic gains in the stress-prone tropics. But partner institutions are at different stages of evolution, which means capacity strengthening must be tailored to institutional strengths and constraints.  

Accelerated Breeding has been strengthening regional CGIAR-NARES-SME collaborative maize breeding networks via activities such as exchanging elite tropical germplasm (inbred lines, trait donors, and breeding populations) through field days, and widely disseminating CIMMYT maize lines (CMLs) requested by institutions globally.  

Partners participate in CGIAR maize stage-advancement meetings – they are given access to multi-location trial data and participate in the selection process of promising hybrids to be advanced from the different breeding stages. CGIAR maize teams also assessed the capacity of different NARES institutions, and formulated continuous improvement plans in consultation with respective NARES teams for further support.  

Better varieties

Systematic integration of new breeding techniques and innovations in CGIAR maize breeding pipelines are leading to better varieties, at a much faster pace, and at lower cost. Given the impacts of climate change, this is indeed the need of the hour.  

Maize breeders need to respond rapidly to emerging and highly destructive insect-pests and diseases. For instance, the invasion of fall armyworm (FAW) in Africa (since 2016) and Asia (since 2018) has ravaged maize crops across more than 60 countries. CGIAR maize team in Africa responded to this challenge and made progress in identifying diverse sources of native genetic resistance to FAW, resulting in elite hybrids and open-pollinated varieties (OPVs) adapted to African conditions. 

Since 2017, CIMMY has strengthened the maize insectary capacity of KALRO-Katumani by optimizing the FAW mass rearing protocol and screening of maize germplasm under FAW artificial infestation at Kiboko Station, Kenya. The station now has sixteen 1,000m net houses. The intensive work since 2018 led to identification of FAW-tolerant inbred lines by CIMMYT and their distribution to over 90 public and private institutions in 34 countries. 

NARES partners across 13 countries in Africa have undertaken national performance trials of three FAW-tolerant hybrids developed by CIMMYT. Kenya, Zambia, Malawi, South Sudan and Ghana released the three hybrids in 2022-23, while several more countries are expected to release these hybrids in the coming months.

Climate change is also exacerbating maize diseases. Affecting at least 17 countries in the Americas, the Tar Spot Complex (TSC) disease affects maize in the cool and humid regions. It causes premature leaf death, weakens plants, and reduces yields by up to 50%. CIMMYT maize team in Mexico has mapped genomic regions conferring TSC resistance, and is using these markers in breeding programs.  

The Global South is also particularly vulnerable to drought and high temperature stresses. In the past five years, 20 drought- and heat-tolerant maize hybrids have been released in Asia, including Bangladesh, Bhutan, India, Nepal, and Pakistan. Socio-economic studies in India and Nepal showed that farmers who adopted these hybrids realized higher grain yields, and increased income compared to the non-adopters. 

In 2022, certified seed production of CGIAR multiple stress-tolerant maize varieties reached 181,119 metric tons in sub-Saharan Africa (from 72,337 tons in 2016). This is estimated to cover ~7.4 million hectares, benefiting over 46 million people in 13 countries. 

With maize facing unprecedented threats from climate change-induced stresses in the rainfed stress-prone tropics, CGIAR maize breeding programs working closely with NARES and private sector have demonstrated remarkable success in breeding as well as deploying climate resilient maize.  These efforts rely on better processes and modern breeding tools, leading to drastically reduced breeding cycle time, cost saving, and improved efficiency.  

The resulting improved varieties–resilient to major environmental stresses, diseases and insect-pests–are increasingly adopted by smallholders across sub-Saharan Africa, South Asia, and Latin America, showing that tomorrow is already here. The work continues to ensure that maize remains a constant source of food security and prosperity for generations to come in the tropical regions.
