A blueprint for soil health initiatives

Written by dmedina on . Posted in Blogs.

Ethiopia’s agricultural and food production systems face significant challenges due to soil acidity. Approximately 41% of the country’s cultivated land is affected, with 28% of this area being highly acidic. Heavy rainfall and inherent soil properties are significant drivers of this, and practices like continuous residue removal greatly accelerate these conditions.

The resulting acidic soil conditions can severely limit the uptake of critical nutrients, leading to lower yields and poorer crop responses to inputs. As a result, Ethiopia’s soil acidity conditions constrain the production and productivity of the country’s main staple crops and compromise efforts to achieve national food security. To help address these problems, policymakers, technical experts, and development partners in Ethiopia have come together to advocate for innovative data-driven solutions to remediate acid soils to raise crop yields and promote sustainable economic growth.  

“At a national workshop convened by CIMMYT and the One CGIAR initiative on Excellence in Agronomy on 29 July 2024 in Addis Ababa, experts from CGIAR, the Ministry of Agriculture (MoA), the Ethiopian Institute of Agricultural Research (EIAR), universities, regional research institutes, the national soil health task force, NGOs, and other key stakeholders gathered to discuss acid soil management in Ethiopia. Participants emphasized that proper management of soil acidity could increase fertilizer use efficiency from 20% to as much as 90%, depending on the initial acidity levels and specific nutrients involved.

Tackling soil acidity 

“Acidic soils are complex and widespread, affecting millions of hectares of arable land in Ethiopia,” said Tesfaye Shiferaw, an agronomist with CIMMYT’s Sustainable Agrifood Systems program and regional lead for the One CGIAR initiative on Excellence in Agronomy. “We understand the situation well and have developed innovative solutions under the GAIA project to address the issue. The spatial targeting framework created within the project represents a significant breakthrough, which the MoA has incorporated into Ethiopia’s nationwide acid soil reclamation initiative.”

Feto Esimo, Director General of EIAR, highlighted, “Addressing soil acidity is critical for enhancing food security and economic development in Ethiopia. A few years ago, we appealed to partners to intensify their efforts in creating sustainable strategies with lasting impacts for future generations. We are now seeing the GAIA project’s ongoing efforts effectively addressing these issues and offering potential solutions.”

The GAIA project approach

Researchers on the GAIA project have been evaluating alternative approaches to managing soil acidity, with a particular focus on lime application. This method aims to reduce aluminum toxicity and improve the availability of essential nutrients such as phosphorus (P), calcium (Ca), magnesium (Mg), and potassium (K) in the soil. Additionally, liming decreases the solubility and leaching of heavy metals and offers benefits for legumes, such as increased microbial activity and enhanced biological nitrogen fixation. The GAIA team’s detailed evaluation includes core activities like spatial targeting to identify priority areas for liming, determining optimal lime application rates, and assessing profitability for specific crop types.

The primary goal in Ethiopia is to guide targeted investments for effective soil health reclamation and increased agricultural productivity through liming and enhanced nutrient management. The project aims to establish a strategic spatial targeting framework, serving as both a policy tool and a blueprint for soil health management. This framework is designed to optimize lime application, ensuring it is prioritized in areas where it can deliver the highest return on investment for farmers and the government. Project outcomes also include expanding this framework for broader application.

Major project outcomes in Ethiopia 

The GAIA research team conducted an in-depth investigation into the interactions between lime and fertilizer, developed a workflow and an essential policy tool integrated into the Ethiopian National Soil Information System (NSIS), and presented evidence-based recommendations on acid soil remediation to national and regional policy forums. The following significant system-level accomplishments have resulted from CIMMYT and partners’ research-driven recommendations.

Firstly, the Ethiopian Ministry of Agriculture (MoA) recognizes the GAIA project’s model as a successful blueprint for implementing and scaling up acid soil remediation nationwide. The government has launched a plan to reclaim 300,000 hectares of acidic cropland in 2024–2025, targeting around 10% of affected areas identified through the spatial targeting framework. To support this initiative, 1.4 billion ETB (approximately 12 million USD) has been allocated to manage acidic agricultural land. Additionally, at the National Stakeholder Consultation Forum on Acid Soils held in Bonga town, South-Western Region, in April 2023, the Ethiopian government prioritized soil acidity as a key focus. Since then, the government has reinforced its commitment to soil health programs, incorporating lime as an essential input alongside improved seeds and fertilizer.

These storylines were highlighted in July 2024 during a national working group meeting aimed at streamlining acid soil management strategies across Ethiopia. The meeting, led by GAIA and EiA in collaboration with the MoA and supported by the One CGIAR initiative EiA, underscored the strategic progress made by the GAIA project in addressing soil acidity. According to Feto Esimo, Director General of the EIAR, these advancements signify a substantial improvement, promising a lasting impact beyond the current agricultural season. He expressed appreciation for the project’s achievements and advocated for its expansion to serve as a model for similar soil health programs across the country.

“Lime is the most widely used remedy, and its effectiveness in increasing yields when combined with fertilizer is well-documented,” noted Temesgen Desalegn, Director of Natural Resources Management Research at EIAR. “In this context,” he continued, “the GAIA project is timely, offering a multifaceted approach to soil health management, not limited to acid soils. The project’s model has been widely welcomed and could provide a comprehensive strategy for other soil health initiatives in Ethiopia.”

The national working group meeting reached a consensus on recognizing project outcomes that drive system-level impacts. This effort to build a strong consensus extends beyond Ethiopia; it reflects a broader continental trend, highlighted by the Africa Fertilizer and Soil Health Action Plan: 2024–2034. This plan emerged from the Africa Fertilizer and Soil Health Summit held in May 2024 in Nairobi, Kenya, under the theme ‘Listen to the Land,’ organized by the African Union.

The GAIA project, funded by the Bill & Melinda Gates Foundation (BMGF), supports large-scale rehabilitation of acid soils in East Africa through data-driven insights and evidence-based recommendations for decision-makers. Led by CIMMYT in collaboration with various partners across Ethiopia, Kenya, Rwanda, and Tanzania, the project works in partnership with the Excellence in Agronomy (EiA) initiative of the One CGIAR. In Ethiopia, GAIA is implemented in cooperation with the Ethiopian Institute of Agricultural Research (EIAR).

Malho Marndi, a tribal farmer from Odisha, India, has been cultivating rice on her 10-acre farm for many years. However, worsening climate conditions and labor management challenges nearly pushed her to stop growing rice, except for personal consumption. The traditional method of transplanting seedlings into puddled fields was becoming unsustainable, and farmers across Odisha were experiencing yield declines that threatened their livelihoods.

To address these challenges, the Cereal Systems Initiative for South Asia (CSISA) project led by CIMMYT, introduced the Direct Seeded Rice (DSR) technology in select districts under the Odisha government’s DSR-Odisha project. DSR involves sowing rice seeds directly into the field, significantly reducing the need for labor and water—making it an attractive solution for smallholder farmers.

In the Kharif season of 2021, Malho participated in a DSR awareness program led by CSISA. Inspired by the success stories of fellow farmers, she decided to take a leap of faith and implement DSR on her own land.

The results were transformative. By adopting DSR on her 10-acre farm, along with an additional 9 acres she had leased, Malho saw her yields nearly double compared to the traditional methods she had previously used. Encouraged by these outcomes and supported by CSISA’s technical guidance, she expanded her cultivation to 40 leased acres and her original 10 acres in 2022. By 2023, she increased her leased land to 50 acres, bringing the total area under DSR to an impressive 60 acres.

Malho’s success didn’t end there. She became a service provider, investing in a tractor and rotavator to assist other smallholder farmers in her community. In 2023 alone, her machinery was used to support more than 30 acres of land. Today, she empowers both men and women farmers by renting out her equipment and encouraging the wider adoption of DSR.

Through mechanization and improved crop management practices, Malho now independently manages her rice and maize cultivation. Confident about the future, she hopes to see more resource-constrained farmers across Odisha adopt DSR, improving their yields and enhancing their livelihoods.

Context-dependent agricultural intensification pathways to increase rice production in India

Written by dmedina on . Posted in In the media.

Rice is a critical staple for food security and a key export crop for India. The study published in Nature Communications explores context-specific pathways for increasing rice production in India, focusing on sustainable intensification — boosting yields without harming the environment or farm profitability.

The research analyzed over 15,000 field records across seven major rice-producing states in India using advanced machine learning techniques. The study identified nitrogen application and irrigation as key factors limiting yields, particularly in Eastern India (Bihar and Uttar Pradesh). By targeting farms with nitrogen and irrigation deficiencies, the study projects that yield gains could more than triple compared to general recommendations. Specifically, farms suffering from co-limitation by both nitrogen and irrigation could see the most significant gains in productivity and profitability.

Four scenarios for sustainable intensification were evaluated, ranging from blanket application of current nitrogen recommendations to highly targeted interventions. The analysis showed that targeted strategies, focusing on farms with the greatest yield constraints, could significantly improve nitrogen use efficiency and result in greater yields and profitability without excessive resource use.

The study highlights the potential of data-driven, context-specific solutions for rice intensification in India, emphasizing that targeted interventions could offer both higher returns for farmers and better environmental sustainability. It suggests a move away from “one-size-fits-all” approaches towards more precise, farm-specific recommendations based on local conditions and data. This approach could help close yield gaps while aligning with sustainable development goals.

Machakos farmer reaps prosperity with new pigeon pea variety

Written by dmedina on . Posted in News.

In the heart of Ndeini village in Machakos County—a region in Kenya known for unpredictable weather and difficult farming conditions—farmer Festus Muthoka’s story is a testament to resilience and innovation. Festus transformed his livelihood by making strategic crop choices and adopting new pigeon pea varieties, resulting in higher yields and incomes.

“When I couldn’t find a job in Nairobi, I returned to the countryside and realized that the fields held more potential for me,” said Festus. For seven years, he had been growing maize, beans, and local pigeon pea, but inconsistent rainfall made it difficult to achieve the desired yields. Pigeon pea offered new hope, particularly when Festus discovered the new variety ‘Mituki.’

Mituki as a gamechanger

Unlike traditional pigeon pea, which takes up to nine months to mature, the Mituki variety matures in four and a half months and can be harvested two to three times a year. “The first year, I planted three lines of Mituki and saw its potential. It is more profitable to sell pigeon pea when it is green. This variety stays green for a long time, and the demand, especially in local hotels, is very high. I sold it for a good profit,” said Festus.

Now in his third year of cultivating Mituki, Festus has expanded his farm to 4-5 acres with plans to increase it to 10 acres in the next planting season. The financial gains have been substantial. “For my first harvest, I made over US $1,500 by selling green pigeon pea. Even after harvesting, the crop remains lush, allowing ongoing sales,” he said.

Festus’s story shows the importance of pigeon pea as an opportunity crop that meets the needs of farmers in challenging environments as well as in challenging economic times. Rael Karimi, a researcher and breeder at the Kenya Agricultural and Livestock Research Organization (KALRO) in Katumani, played a key role in developing the Mituki variety. “When I first started working on the pigeon pea breeding program, we identified a gap in the local varieties, which took a whole year to mature. The commercial short-duration variety, which matures in three months, had small pods and grain, therefore not acceptable to farmers. Farmers needed early- to medium-maturing varieties with market- and farmer-preferred traits, such as larger grains and pods for ease of shelling for green vegetables. This resulted in the development and release of the Mituki variety in 2018,” she said.

The development and promotion of new pigeon pea varieties involve extensive testing and active farmer participation. “We conducted on-station trials, followed by on-farm testing with farmers to ensure the varieties had the farmer-preferred traits. The Mituki variety is a medium-duration variety, giving two harvests per year, making it very popular among farmers,” Karimi added.

Creating awareness during field days

Promoting new varieties is equally important as developing them. “It’s one thing to release a variety but another to ensure promotion and popularization. If you release it and put it on the shelves, farmers will not be aware that a better variety is available,“ said Rael. This is where on-farm demonstrations and field days are crucial.

Field days are critical in ensuring that new, improved varieties reach the farmers who require them the most, bridging the gap between varietal development and practical application in the field. They also emphasize the importance of using high-quality seeds rather than recycled seeds, which often come with significant challenges.

A field day held in July in Ndeini village effectively raised awareness among numerous farmers about the benefits of the Mituki variety and how it can provide two harvests per year compared to their long-duration local varieties, which only give one harvest in a year.

Seed purity for improved yields

Chris Ojiewo, seed systems lead for the Dryland Crops program at CIMMYT, emphasizes the importance of maintaining seed purity and good farming practices. “Farmers often recycle seeds for years, resulting in cross-pollination and loss of desirable traits. We encourage them to regularly buy new seeds, which ensures high yield and disease resistance. With support from CIMMYT and the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) Project, we are now able to produce and distribute quality seeds to farmers,” he said.

Chris highlighted the challenges of recycling seeds. Genetic impurity is a significant concern due to pigeon pea outcrossing. It prevents such grains from entering the formal value chain and, as a result, reduces farmer profits. Additionally, recycled seeds may accumulate diseases and pests, diminishing crop health. Stored seeds can also have low germination capacity and vigor, leading to poor crop performance.

To address these issues, Chris advocates for behavior change communications to educate farmers on the benefits of using pure seeds. Linking farmers to formal seed value chains ensures that they understand the financial incentives of using pure seeds. Moreover, improving the production, availability, affordability, and timely supply of quality seeds can prevent the need for recycling.

Collaborative efforts in pigeon pea breeding

Ganga Rao, a pigeon pea breeder with the Dryland Crops program, explains how CIMMYT provides support to both farmers and researchers. “CIMMYT has been instrumental in advancing pigeon pea breeding programs by providing technical support and resources. We collaborate closely with local researchers at KALRO to ensure that the new varieties are tailored to the specific needs and conditions of the farmers,” he said.

Through the collaborative efforts of the pigeon pea CGIAR-NARES network, CIMMYT, under the AVISA project, has supported KALRO in producing pigeon pea seed for the Mituki variety. The promotion of this seed used small seed packets of 200g. This approach created demand for the new variety, with many farmers purchasing the seed ahead of the short rains 2024 cropping season. This is an indication that farmers are willing to buy certified seeds when they are made aware of improved varieties that offer both farmer- and market-preferred traits.

Ganga emphasized the importance of continuous improvement and farmer engagement. “Our goal is to develop varieties that are high yielding and resilient to climate stresses and diseases. Through on-farm trials and demonstrations, farmers provide us with valuable feedback, which informs our breeding programs. This collaborative approach ensures that the varieties we release meet the market demands and preferences,” he added.

Ganga emphasized the importance of continuous improvement and farmer engagement. “Our goal is to develop varieties that are high yielding and resilient to climate stresses and diseases. Through on-farm trials and demonstrations, farmers provide us with valuable feedback which informs our breeding programs. This collaborative approach ensures that the varieties we release meet the market demands and preferences,” he added. 

The future of pigeon pea is bright

Festus’s success with Mituki variety demonstrates the potential of strategic crop selection and good agricultural practices. “I now see pigeon pea as a major agro-enterprise for food security and as a significant source of income. The market demand for green pigeon pea is high, and with proper seed management farmers can sustain and improve their livelihoods,” Festus concluded. 

Looking ahead, Karimi is optimistic that more farmers will adopt this new variety. “The future for pigeon pea is bright. We aim to have farmers producing throughout the year, meeting the high market demands and ensuring food security. By aggregating their produce, this will ensure adequate tradable volume which helps farmers negotiate for better prices and achieve greater financial stability,” she said. 

Ganga added, “CIMMYT’s ongoing support in seed production and farmer training is crucial. We are committed to empowering farmers with the knowledge and resources they need to maximize their yields and improve their livelihoods. Pigeon pea has the potential to transform the agricultural landscape in dryland regions.”

As Festus prepares to expand his farm and continue his journey, his story serves as an inspiration to many farmers in Ndeini and beyond. With support and innovations in crop breeding, farmers such as Festus are not only surviving but thriving, turning challenges into opportunities and paving the way for a prosperous future in agriculture.  

Scaling fodder innovations to improve livestock productivity in Zimbabwe’s semi-arid regions

Written by dmedina on . Posted in News.

Gogo Consilia Nyamunda in her pigeon pea field (CIMMYT)

When she first ventured into growing pigeon peas as a baby trial host farmer, Gogo Consilia Nyamunda doubted that intercropping them with maize would bring any benefits, especially given the weather had not been lenient over the past few years in Buhera district, in eastern Zimbabwe. “This year has been the hardest. I’ve never experienced such drought and heat stress, but it’s not just me—it’s affecting the entire country,” says Gogo Consilia. Yet, her production turned out to be better than that of farmers growing only maize, a popular crop in Southern Africa. Encouraged by the results, she expanded her efforts, dedicating half a hectare to pigeon peas. “From just 0.2 hectares of pigeon peas, I still managed to harvest 10 kilograms in these extremely dry conditions. It’s not just for feeding my chickens—other farmers are now interested in the seeds as well,” she explains.

Gogo Consilia Nyamunda is one of twelve farmers experiencing new feed production practices as part of the Livestock Production Systems in Zimbabwe (LIPS-Zim) project, rolled out since 2020 by the International Livestock Research Institute (ILRI) in partnership with CIMMYT, the French Agricultural Research Center for International Development (CIRAD), and the University of Zimbabwe (UZ).

In the face of a changing climate, building the resilience of local farmers is crucial to safeguarding both their meal baskets and livestock feed. In this context, LIPS Zimbabwe has emerged as a strategic initiative, deeply rooted in farmer-driven trials to scale fodder production while maximizing the potential of mechanization for smallholder farmers in Buhera. By integrating improved agronomic practices with scalable fodder production, LIPS Zimbabwe is helping farmers withstand the challenges posed by climate change.

Empowering local farmers through fodder production

In the same district, Shirley Makoni also began as a baby trial farmer, intercropping maize with jack bean, a leguminous crop resilient to drought. Her case highlights the importance of diversifying crops and adapting to the realities of climate change: despite initial skepticism, Shirley found that jack beans not only survived the drought but also provided valuable feed for her cows. “I didn’t think anything would come out of it, but the cows love the leaves and seeds. They’ve gained weight, and the crop has been easy to manage,” she shares. While her maize and other crops failed due to the severe weather, jack bean proved to be a reliable source of feed, allowing her to bale the leaves and even share the harvest with others.

One of the key strategies employed by LIPS Zimbabwe is the promotion of resilient fodder crops that can thrive under harsh climatic, semi-arid conditions where potential evapotranspiration far exceeds seasonal rainfall, which is often below 600 mm. This approach not only ensures a reliable source of feed for livestock but also contributes to the overall resilience of farming systems. The success story of farmers like Gogo Consilia Nyamunda highlights the transformative impact of these efforts.

“The idea of testing new innovations has paid off. Despite the poor sandy soils in Buhera, these fodder crops (jack bean and pigeon pea) have done well!” says Isaiah Nyagumbo, a Systems Agronomist leading the CIMMYT component of the LIPS-Zim project. “This means we now have a more diverse range of leguminous fodder crop species that can be grown in these semi-arid conditions, apart from the more common ones such as mucuna, lablab, and cowpeas.”

Some preliminary laboratory results also suggest that jack bean contains much higher crude protein than popular fodder legumes like mucuna. Jack bean could thus offer a new resilient feed option for farmers in these drought-prone regions and can be grown as an intercrop or in rotation with cereals.

Transforming fodder production through mechanization

Tying the LIPS Zimbabwe project together is the introduction of the mechanization component, from planting to processing the fodder crops, which is crucial for increasing the scale of fodder production in Zimbabwe’s semi-arid regions. By processing forage legumes such as jack bean, lablab, pigeon pea, mucuna, and cowpea, farmers can ensure a steady supply of nutritious feed for their livestock, even in the face of unpredictable weather patterns.

Local farmers in Buhera have been equipped with machinery such as a chopper grinder, hay balers, planters, and tractors, and trained to use and maintain the equipment. “Among the machinery at hand, the hay baler has been a great win for me, especially for the cows,” says Gandani Nhachi. “Last season, I made 27 bales of fodder, which has been vital for my herd. I’ve also grown my goat herd from 16 last year to 35 this year,” he proudly shares.

Building resilience for the future

As climate change continues to challenge farmers, initiatives like LIPS Zimbabwe are essential for building resilience. By combining traditional knowledge with modern practices, scaling fodder production, and embracing mechanization, farmers in Buhera are better equipped to protect their livelihoods and ensure food security. As Gandani puts it, “Climate change is inevitable, but with the right practices, we can still thrive. When I give my goats food, they multiply. Even if one side fails, all hope is not lost.”

Wild wheat: The key to food security in a warming world

Written by dmedina on . Posted in Blogs.

About a billion liters of fungicide.

That’s how much farmers have saved this century, through use of disease-resistant wheat varieties. Modern wheat can thank its “wild relatives” — grassy cousins millions of years old and tested through extremes of earth’s climate — for most of its resistance genes.

Despite such remarkable achievements in wheat breeding, we’ve only scratched the surface of the genetic potential in wheat’s wild relatives. With climate change intensifying and the rapid evolution and spread of pathogens — a new strain of fungus can circulate in the jet stream—it’s imperative that we increase investment in researching this largely untapped genetic diversity. Doing so could revolutionize wheat production, ensuring food security while dramatically reducing agriculture’s environmental footprint.

Without such efforts, epidemics or pandemics could devastate yields, potentially leading to massive applications of toxic agrochemicals and increased selection pressure for pests and diseases to develop resistance. The consequences would be far-reaching, impacting not only food security and the environment, but also geopolitical stability, potentially triggering human migration and conflict.

Today, wheat is the most widely grown crop on Earth, providing 20% of all human protein and calories and serving as the primary staple food for 1.5 billion people in the Global South.

However, with its future under threat, standard breeding approaches can no longer keep up with the pace of climate change. Research shows that climate shifts from 1980-2008 reduced wheat harvests by 5.5%, and global wheat production falls 6% for every degree-centigrade increase in temperature.

Wheat science urgently requires enhanced investments to scale up genetic studies of wild relatives, utilizing next-generation breeding tools. These tools include gene sequencing technologies, big-data analytics, and remote sensing technologies. Satellite imagery makes the planet a laboratory, allowing researchers to monitor traits like plant growth or disease resistance globally. Artificial intelligence can super-charge breeding simulations and quickly identify promising genes that enhance climate-resilience.

The basic genetic resources are already available: more than 770,000 unique seed samples are stored in 155 seed banks across 78 countries. These samples represent the full scope of known wheat genetic diversity, from modern varieties to ancient wild relatives and landraces developed at the dawn of agriculture.

What’s missing is funding to accelerate the search for specific genes and combinations that will fortify wheat against harsher conditions. This requires political will from key decision-makers and public interest. Nothing is more important than food security and the environmental legacy we leave to our children.

Harnessing the power of microorganisms

The genetic variation in seed banks is largely absent in modern wheat, which became genetically separate from other grass species 10,000 years ago and has undergone recent science-based breeding, constricting its diversity. Wheat needs its cousins’ diversity to thrive in a changing climate.

Beyond climate resilience and disease resistance, wild wheat relatives offer another exciting avenue for environmental benefits: enhanced interactions with beneficial microorganisms. These ancient grasses have evolved intricate relationships with soil microbes largely absent in modern wheat.

Some wild wheat relatives can inhibit soil microbes that convert ammonium to nitrate. While both are usable nitrogen forms for plants, nitrate is more prone to loss through leaching or gaseous conversion. Slowing this process of conversion, called nitrification, has profound implications for sustainable agriculture, potentially mitigating greenhouse gas emissions, improving nitrogen-use efficiency, and decreasing synthetic fertilizer use.

As proof of concept, the first and only crop (so far) bred to promote microbiome interaction is wheat, using a gene from a wild relative (Leymus racemosus) to slow nitrification.

In addition, wild relatives often form more effective symbiotic relationships with beneficial soil fungi and bacteria, enhancing nutrient uptake, drought tolerance, and natural pest defenses. Reintroducing these traits could reduce chemical inputs while improving soil health and biodiversity.

The benefits extend beyond the field. Wheat varieties that use water and nutrients more efficiently could reduce agricultural runoff, protecting water bodies. Enhanced root systems could increase soil carbon sequestration, contributing to climate change mitigation.

By systematically exploring wild wheat’s microbial interaction traits, wheat varieties can be developed that not only withstand climate challenges but also actively contribute to environmental restoration.

This represents a paradigm shift from crop protection through chemicals to resilience through biological synergies. Indeed, even a fraction of the US $1.4 trillion spent annually on agrochemical crop protection could work wonders to fortify wheat against present and future challenges.

The path forward is clear: increased investment in researching wild wheat relatives can yield a new generation of wheat varieties that are not just climate-resilient, but also environmentally regenerative. This will be a crucial step towards sustainable food security in a changing world.

Nane Nane fair in Tanzania showcases agricultural innovation and collaboration

Written by dmedina on . Posted in News.

Partners at the AID-I exhibition booth (Photo: CIMMYT)

In Tanzania, the first week of August is all about agriculture. From August 1 to 8, agricultural fairs, also known as Nane Nane fairs, are held all over the country to recognize the contribution of farmers to the national economy. ‘Nane Nane’ in the local language means ‘eight eight,’ referring to August 8, which is celebrated as Farmers Day in the country.

Organized by the Agricultural Society of Tanzania, these fairs serve as a landmark event for agricultural stakeholders across the region. This year, the 31st edition of the fair was organized at the Nzuguni grounds in Dodoma. It saw 500 exhibitors, including smallholder farmers, agricultural enterprises, public and private sector entities, and government officials.

Themed ‘Embrace Visionary Leadership for Agricultural Transformation,’ the event emphasized the need for leadership commitment to sustainable agriculture, while highlighting the critical role of agriculture in Tanzania’s economic growth and food security.

The Southern Africa Accelerated Innovation Delivery Initiative (AID-I), funded by United States Agency for International Development (USAID) and implemented by CIMMYT, along with several partners, played a prominent role at this year’s fair. In addition to raising awareness of the innovative work being done, the fair provided a platform for AID-I and its partners to showcase a range of innovative agricultural technologies designed to address the specific needs of Tanzanian farmers. The event also enabled AID-I and its partners to interact directly with farmers and entrepreneurs, resulting in valuable feedback. 

Celebrating the Success of AID-I Beneficiaries at Nane Nane

 

The Nane Nane fair was more than just a display of agricultural technologies. It was also a celebration of the successes of local entrepreneurs who had benefited from AID-I’s support.

Among them was Sarah Mashauri, an entrepreneur from the Tabora region, who ventured into the business world by producing and selling maize flour, both wholesale and retail. Starting with only one sack of maize and a loan of 100,000 Tanzanian shillings (approximately US$36), Sarah faced numerous obstacles, including regulatory challenges that resulted in the Tanzania Food and Drugs Authority confiscating her items. The AID-I project recognized her potential and resilience. She was equipped with a milling and dehulling machine, which significantly improved her business. “Before the AID-I project came into my life, I was struggling on my own,” she said. “The support, coupled with the extensive training they provided, enabled me to scale up my operations. I went from employing seven people to 35, and my business expanded significantly. I am now able to source raw materials easily from small-scale farmers, thanks to the networks and training provided by AID-I.”

Agatha Laiza, managing director of Seasoning Palate, a food products company operating under the brand name Tobi Product in Dar es Salaam, is another entrepreneur who benefited from AID-I’s support. Agatha specializes in peanut butter, crunchy nuts, and peanut oil. Her journey began in 1996 with a focus on food product processing. She later realized the potential in peanut production and shifted to adding value to peanuts, while also addressing the critical issue of aflatoxin contamination. With support from AID-I, Agatha was able to build solar dryers for farmers and provide them with high-quality seeds, significantly reducing the risk of aflatoxin in their crops. “The support from USAID, CIMMYT, and AID-I has been invaluable,” Agatha said. “They have helped us build confidence among our farmers, reducing ground nut loss and ensuring safe, quality produce. Our factory, which can process up to three tons of peanuts daily, now operates more efficiently and our products are safer and more reliable.”

Aithan Chaula, executive director of the Dodoma Agriculture Seed Production Association (DASPA), also benefited from the AID-I project’s support. Since beginning pigeon pea production in 2022, DASPA saw substantial growth in demand for pigeon pea seeds, partnering with ALSSEM, a local seed production company.

DASPA expanded its operations to produce quality declared seeds (QDS) and certified seeds, catering to a growing market. Aithan attributed their success to the strategic support from AID-I and partnerships with organizations such as CIMMYT and ALSSEM. “The collaboration allowed us to expand our production capabilities and reach more farmers across various regions,” he said. DASPA is currently working with approximately 20,000 farmers and plans to increase this number by distributing small seed packs and conducting field demonstrations.

“This year at Nane Nane, we were able to distribute small packs of pigeon pea seeds to approximately 1,200 farmers to plant and farm,” said Aithan. “This effort, supported by AID-I, ensures that pigeon pea cultivation becomes well-known and widely adopted by farmers, contributing to both food security and income generation.”

Dr. Michael A. Battle Sr., the United States Ambassador to Tanzania, paid a visit to the AID-I exhibition booth. He engaged with AID-I representatives and the exhibitors, praising their innovative efforts to advance climate-smart agriculture and enhance food security. “It’s a joy to be participating in Nane Nane, particularly because USAID is interested in assisting Tanzania not only to become food secure but also to help with East Africa’s food security and ultimately the continent’s food security,” said Ambassador Battle Sr. He added that it was fulfilling to see the entire value chain of agriculture and agribusiness involving young people and old people engaged in the process of making Tanzania wealthier and more food secure.

For AID-I and its partners, the fair was a crucial opportunity to highlight ongoing initiatives and foster new partnerships. Peter Setimela, the Legume Seed Systems lead for AID-I, emphasized the importance of such events. “Our work in accelerating innovative technologies and ensuring they reach the farmers is reliant on strong partnerships. We bring these technologies to farmers by strengthening local seed systems, connecting farmers to financial services and products, and providing advisory services,” he said.

How effective soil aggregate management can boost productivity and climate resilience

Written by dmedina on . Posted in News.

Soils are the bedrock for plant health and sustenance, but how do we protect and enhance them to maximize their nutritional potential? Years of conventional farming practices have left many soils depleted, raising urgent concerns about how to rejuvenate them. The recent El Niño event during the 2023/24 farming season in southern Africa, bringing extreme weather conditions—ranging from prolonged droughts to intense floods—has exposed the vulnerability of these soils. Poorly managed soils, already strained by years of excessive tillage and lack of cover, struggle to retain moisture under such stress, leading to crop failures even after rainfall.

However, conservation agriculture (CA) offers a vital solution. By improving soil structure and moisture retention, CA practices provide a lifeline for crops in challenging conditions. Recognizing this, CIMMYT scientists are actively promoting CA among smallholder farmers across sub-Saharan Africa, highlighting its critical role in sustaining soil health and resilience in the face of climate challenges.

Described as lumps of soil particles that bind together strongly, soil aggregates play a vital role in maintaining soil health, supporting plant growth, and sustaining agricultural productivity. Formed by the combined effects of biological, chemical, and physical processes, the structure and stability of soil aggregates are crucial for several soil functions—primarily water infiltration, root growth, and resistance to erosion. Soil aggregates consist of various soil particles, including sand, silt, clay, and organic matter. There are different types of soil aggregates, including macroaggregates (>0.25 mm) and microaggregates (<0.25 mm), with macroaggregates typically more stable and beneficial for soil structure and functions.

Demonstrating the value of soil aggregate stability

Imagine three soil aggregate samples taken from the same field but under different management regimes—from virgin soil that has not been previously cropped, to land under conservation agriculture practices for the last 5 to 8 years, and soil conventionally ploughed annually before crop planting for many years. When these soil aggregates are gently immersed in clear water, stark differences can be noted. The aggregates from conventionally tilled soil, weakened by years of intensive cultivation, quickly disintegrate, turning the water murky and brown.

In contrast, the aggregates from virgin soil remain intact, preserving the water’s clarity even after several hours. The CA soil aggregates exhibit much better stability than those from the conventionally tilled soil but fail to remain as intact as those from the natural virgin soil. A simple lesson is drawn from this demonstration! Restoring degraded soils is a serious challenge. Even after 5 years of CA practices, soil organic carbon levels may only show modest improvement, and the aggregates, while more stable, still don’t match the condition of aggregates from virgin soil.

Soil recovery from a degraded state is a slow process that is not “a walk in the park.” Transitioning from conventional tillage to CA is challenging and slow, requiring years to rebuild organic matter and improve aggregate stability. Patience and careful soil management are vital, as degradation can occur rapidly, but recovery is a lengthy process. However, incorporating organic soil amendments like manure and compost, along with diversifying crops by introducing legumes such as cowpea, groundnut, soybean, mucuna, and pigeon pea, can accelerate this recovery. While degradation occurs rapidly, soil restoration demands a long-term commitment, but the rewards are worth the effort.

Exploring conservation agriculture as a source to improve soil health

Conservation agriculture is built on three key principles: reduced soil disturbance, permanent soil cover, and diverse crop rotation. Minimizing soil disturbance helps preserve soil structure, while permanent soil cover shields the soil against splash erosion and boosts microbial activity. Crop rotation enhances soil fertility, maintains aggregate structure, and disrupts pest and disease cycles. These principles are essential for soil recovery and the retention of organic matter.

Among these, permanent soil cover is often the most challenging for farmers to implement, yet it is critical for effective soil management. Demonstrating its importance, a simple test with water applied to soil samples with varying levels of cover illustrates splash erosion effects.

“Such a simple test mimics real-life conditions farmers face during rains. Soils without cover suffer significant erosion, while those with minimal or substantial cover show reduced erosion and improved water retention. This emphasizes the importance of maintaining permanent soil cover to foster microbial activity and enhance soil health,” highlighted Isaiah Nyagumbo, cropping systems agronomist.

In a nutshell, soil aggregate management is fundamental to climate resilience and agricultural sustainability. Through the adoption of conservation agriculture practices, smallholder farmers can significantly improve soil health, enhance water and nutrient retention, and increase crop resilience to climate stress. The journey from degraded to healthy soil is long and challenging, but with careful management and patience, the benefits are profound and lasting. By understanding and implementing these principles, farmers can build a more sustainable and resilient food system.

Rajendra Kathariya, a 41-year-old resident of Joshipur-2 in Kailali district, far-west of Kathmandu, has transformed his life and that of his family of five through commercial agriculture. Despite many challenges, Rajendra has remained committed to achieving financial sustainability through enhanced farming practices. Over the last two years, his partnership with Nepal Seed and Fertilizer (NSAF) and CIMMYT, in collaboration with Nisrau Multipurpose Cooperative, a partner cooperative of NSAF, has been instrumental in his success. 

Moving from traditional to modern farming

Previously, Rajendra cultivated cereal crops using traditional methods which often led to food crises for his family. However, he has now shifted to cultivating various crops throughout the year using modern farming techniques on his 1.02 ha of land and an additional 2.71 ha which he has leased. 

“Before NSAF’s support, we only cultivated two crops per year. Now we harvest three crops and are considering commercial maize production,” Rajendra said. 

Remarkable achievements in crop production

Last year, Rajendra cultivated rice on 3.72 ha, yielding 8.8 metric tons (t) worth NPR 250,000 (US $1,880.71). Similarly, he sold 3.8t of spring maize from 1.35 ha, earning NPR 110,000 (US $827.51). This year, he expanded maize cultivation to 2.03 ha, with an expected income of NPR 200,000 (US $1,504.57). His potato crop yielded 5.5t worth NPR 125,000 (US $940.35), with an additional 5.5t stored for future sale. 

In addition to crops, Rajendra has established a pig farm, earning NPR 400,000 (US $3,009.13) in 2023 from selling pigs. He received a feed-making machine for pigs from NSAF, under its support to agribusiness Micro, Small and Medium Enterprises (MSMEs).  

Embracing modern technology and techniques

Rajendra uses both organic and chemical fertilizers and follows improved farming techniques such as hybrid seeds, line sowing, and machinery use. He owns a mini tiller and rents other machinery as needed. This year, with support from NSAF, he used a drone to spray fertilizer on his spring maize, significantly reducing labor and time. 

“I have viewed videos of drones spraying fertilizer but never imagined it happening on my spring maize land. As a demonstration, 0.57 ha was used for nano urea spraying. The task was completed within five minutes of the drone taking flight. Similarly, I was astonished to learn that a drone can cover 2.02 ha in a mere 20 minutes,” he shared. 

Intercropping and future plans

Rajendra has also implemented intercropping, combining maize with legumes on a 0.10-hectare plot. “Spring maize-legume intercropping is productive and effective for farmers such as me. We can make a profit from legumes, as well as spring maize. I will continue using this practice in the future,” he said. 

Financial investments and community impact

The profits from agriculture have helped Rajendra to manage his household comfortably. He can now provide education for his four children, manage household expenses, and also pay the loan that he had taken for his household expenses. In addition, he recently invested NPR 250,000 (US $1,880.71) to build a new pig shed. He also sells his produce in local markets at Joshipur, Kailali.  

“I have travelled a long way from being a subsistence farmer to engaging in commercial farming. This shift from traditional to improved farming technologies has been made possible with the support of NSAF/CIMMYT. I am grateful for their assistance and encouragement,” Rajendra said. 

Vision for sustainability

Rajendra’s story reflects his dedication and hard work. “I was working as a daily wage laborer in India, hoping to secure a promising future for my children. Today, I can achieve complete sustainability through agriculture and provide quality education and a better life for my children,” he shared.

Buffering Climate Extremes in Zambia: The Essential Role of Delivery with a Difference

Written by dmedina on . Posted in Blogs, Features.

Dr Sieg Snapp is Program Director, Sustainable Agrifood Systems, International Maize and Wheat Improvement Center (CIMMYT)

Climate change is upending weather patterns across Africa, presenting dire challenges for farming communities. In Zambia, the impact is particularly harsh. Agriculture is the lifeblood of the economy, with two-thirds of the country’s workforce employed in agriculture, and 78% of these workers are women.

The country faced a severe El Niño during the 2023/2024 season, causing a severe drought that devastated over 1 million hectares of cropland. The president declared it a national disaster. El Niño events typically result in catastrophic drops in crop yields, often reducing maize harvests by 30-40%. These events not only impact food security but also hinder economic growth, with the agricultural sector’s contribution to Zambia’s GDP dropping from 9.4% to 3.39%.

The devastating El Niño-induced drought in Zambia is starkly illustrated by the story of Melody Limweta, a 31-year-old farmer. She and her husband, Collins Manenekela, have seen their already fragile livelihood pushed to the brink by severe water shortages. Typically, they rely on dry season gardening and small-scale farming, including raising chickens, during the rainy season. However, the drought has dried up local water sources, making gardening impossible and sharply reducing their income. The couple’s practice of planting maize in the same field each year with recycled seeds and traditional methods has worsened their situation, as the El Niño-induced rainfall deficits have led to poor yields. Their primary source of food and income has withered in the field due to insufficient rainfall.

A consortium of partners led by the International Maize and Wheat Improvement Center (CIMMYT) have joined together as a rapid delivery hub for these challenging times, providing vital support to rural communities and families such as Melody and Collins. Farmers have a strong voice in this unique delivery mode. With support from the people of the U.S. government, the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) is promoting access to drought-tolerant crops, climate-busting and nutritious legume seeds, agricultural advice and early warning systems to combat climate change. AID-I provides critical support to ensure that millions of smallholder farmers in the Haut-Katanga region of DR Congo, Malawi, Tanzania, and Zambia have access to information and innovations needed for gains in food production that help buffer drought, flood and rising food, fuel, and fertilizer prices.

Speed and Scale: planting drought-tolerant maize

The idea of the ADI-I as a rapid delivery hub is to make available innovations and agronomic information at both speed and scale. Traditional farming methods and crops struggle with climate extremes like El Niño, which bring prolonged dry spells and heatwaves. Drought-tolerant maize varieties offer a promising solution by enhancing agricultural resilience. These adapted maize varieties yield 30-50% more than traditional ones under drought conditions, as demonstrated in recent trials during El Niño periods. However, these improved varieties are only useful when in farmers’ hands.

Working with local partners, AID-I is scaling drought-tolerant maize varieties to help Zambian farmers manage unpredictable weather patterns. In the 2023/2024 season, approximately 27% of Zambia’s smallholder farmers saw a significant boost in their maize harvests, benefiting over 900 thousand people in drought-affected regions, owing to drought-tolerant maize varieties. Over six hundred thousand households planted drought-tolerant maize varieties and produced 235 thousand metric tons of maize, accounting for 19% of Zambia’s maize production in the 2023/2024 season. This is huge return, as only 10% of the maize-growing area being planted with these resilient varieties.

Crop diversification for family nutrition

In addition to drought-tolerant maize, studies indicate that diversifying with legume crops is crucial for managing weather extremes, especially droughts and for improving soil health. Planting legumes helps spread the risk with varied planting and harvest times, cushioning the impact of erratic rainfall on crop yields. Women can feed their families due to crops like peanuts that mature early and need less rainfall. The benefits are sustained over time, as combining legumes with cereals improves overall nutrition and soil health, even amid unpredictable weather.

To support this effort, AID-I linked over 2,000 farmers to high-quality seeds for groundnuts (peanuts) and soybeans. On average, each household harvested about 80 kg of groundnuts and 175 kg of soybeans, earning roughly $75 and $58, respectively. Collectively, this initiative produced about 205 metric tons of these crops, accounting for around 14.3% of Zambia’s total production in the drought-stricken season. Farmers had a voice in choosing which crop varieties to grow through a feedback system called ‘let’s chat’ where with an ordinary flip phone farmers could call in and learn from their neighbour’s recorded commentary and testimonials. For the first time ever, farmers could provide comments on which crops they preferred, providing a lifeline of communication with agritraders, government and agricultural advisors.

A recent assessment found that Zambian women made up 60% of those benefiting from cowpeas, 65% from groundnuts, 62% from soybeans, and 36% from drought-tolerant maize.

Forewarned is forearmed – early-warning systems

Weather information services, especially early warnings about upcoming droughts, are vital for helping farmers adapt to climate change. Accurate and timely weather forecasts enable farmers to make informed decisions about planting, resource use, and crop management. This reduces losses and boosts productivity. Research shows that access to climate information can significantly increase crop yields and incomes, with some farmers experiencing up to a 66% boost in yields and a 24% rise in income.

The forecast of an El Niño for the 2023/2024 season prompted an early warning campaign to raise awareness about the hazards associated with El Niño and provide response mechanisms for smallholder farmers.  AID-I used an Interactive Voice Response platform hosted by Viamo, a global social enterprise that uses mobile technology to connect people to valuable information and services. This rapid El Niño advisory campaign reached over 500 thousand farmers, with 60% male and 40% female listeners, and 93% of them under 35 years old. The campaign provided crucial advice on planting schedules, drought-resistant crops, and water-saving techniques.

Additionally, AID-I established demonstration sites that showcased effective winter crop production methods and introduced over 2,000 farmers to innovative agricultural practices. These interventions significantly improved farmers’ ability to respond to the drought.

Looking ahead

Scaling the adoption of drought-tolerant maize, improved legumes, and timely advisories is vital to protecting Zambia’s agriculture from climate extremes. The introduction of an AID-I-supported digital advisory campaign in September 2023 was a turning point for farmers like Melody and Collins. By engaging with the content, they learned about improved seeds, crop rotation, and better agronomic practices, which helped them cope with ongoing challenges and protect their resources. Initiatives like this can help families on the margins survive and rebuild agricultural production faster.

AID-I’s impact on families like Melody and Collins shows that investing in rapid delivery hubs is crucial for building resilience in farming communities. Expanding such initiatives will ensure more smallholder farmers have access to the innovations needed to maintain or increase food production amid climatic challenges.

Additionally, studies by organizations like Springer and the American Geophysical Union highlight the importance of integrating rapid delivery hubs into mainstream agricultural programs to enhance climate resilience and food security. Therefore, this necessitates an open call for international development allies—including donors, governments, NGOs, and businesses—to incorporate initiatives like AID-I into broader agricultural agendas, essential for fostering resilience and ensuring the future stability of farming communities in Zambia and beyond.
