Staff of the Nepal Seed and Fertilizer (NSAF) project conducted a three-day “training of trainers” workshop on integrated soil fertility management and related practices for commercial rice farming, for 50 agricultural technicians from 50 farm cooperatives in districts of mountainous midwestern Nepal and its lowland Terai Region.

Held in Nepalgunj, midwestern Nepal, the workshop focused on the “4Rs” for soil fertilization—right source, right rate, right time, and right place—along with other best farming and soil nutrient stewardship practices for rice-based farming systems.

“Subject matter was comprehensive, covering variety selection, transplanting, weeding, management of nursery beds, fertilizer, irrigation, controlling pests and diseases and proper handling of rice grain after harvest,” said Dyutiman Choudhary, NSAF project coordinator and scientist at CIMMYT. “Topics relating to the integrated management of soil fertility included judicious application of organic and inorganic fertilizer, composting and the cultivation of green manure crops such as mungbean and dhaincha, a leguminous shrub, were also included.”

Support to sustainably boost Nepal’s crop yields

With funding from the United States Agency for International Development (USAID), the NSAF project promotes the use of improved seeds and integrated soil fertility management technologies, along with effective extension, including the use of digital and information and communication technologies.

Agriculture provides livelihoods for two-thirds of Nepal’s predominantly rural population, largely at a subsistence-level. Rice is the nation’s staple food, but yields are relatively low, requiring annual imports worth some $300 million, to satisfy domestic demand.

Workshop participants attended sessions on digital agri-advisories using the Geokrishi and PlantSat platforms and received orientation regarding gender and social inclusion concerns and approaches—crucial in a nation where 70% of smallholder farmers are women and exclusion of specific social groups remains prevalent.

“Topics in that area included beneficiary selection, identifying training and farmer field day participants, and support for access to and selection of improved seed and small-scale farm equipment,” explained Choudhary. “The participants will now go back to their cooperatives and train farmers, local governments and agrovets on improved rice production.”

Nepal scientists and national research programs have partnered with CIMMYT for more than three decades to breed and spread improved varieties of maize and wheat and test and promote more productive, resource-conserving cropping systems, including rotations involving rice.

Cream of the crop: Developing the next generation of wheat scientists is key to sustaining wheat production in Pakistan

On July 17-18, 2023, 87 wheat scientists gathered to learn about new approaches and methods for wheat improvement in Faisalabad, Pakistan. CIMMYT and the Wheat Research Institute, Faisalabad (WRI-FSD) jointly organized a two-day training. The course covered two topics: high throughput genotyping technologies and high throughput phenotyping platforms. The trainees, who were able to attend in person or remotely and 27% of whom were women, hailed from 17 NARES partners across Pakistan.

After being welcomed by the Director General of Ayub Agricultural Research Institute (AARI), Akhtar Ali, and CIMMYT’s Country Representative, TP Tiwari, participants received an update on the status of wheat in Pakistan from Muhammad Sohail, national wheat coordinator for the Pakistan Agricultural Research Council (PARC). Subsequently, WRI-FSD Director, Javed Ahmed, discussed wheat research in Punjab, where over 70% wheat is grown in Pakistan. Kevin Pixley, interim director of CIMMYT’s Global Wheat Program, joined the proceedings remotely for a conversation about CIMMYT’s and CGIAR’s collaboration with NARES. Participants discussed the model’s successes, bottlenecks, the role of NARES, and the potential for capacity development. The conversation generated broad interest and suggestions for enhancing the partnership’s effectiveness. Akhtar Ali, Muhammad Sohail, and Javed Ahmed all spoke very highly about CIMMYT’s support in Pakistan.

This event was organized as part of a collaborative project entitled “Rapid development of climate resilient wheat varieties for South Asia using genomic selection” that is jointly managed by Kansas State University and CIMMYT with funding from the USAID Feed the Future program.

“Training emphasized the need for an output-oriented researcher that covered the development of climate-resilient wheat varieties, given the environmental challenges we are experiencing like, drought and heat, and highlighted the importance of innovative methodologies and advanced tools for high throughput phenotyping and genotyping for sustainable and resilient wheat production in Pakistan” said Muhammad Ishaq, a senior research officer and one of the training participants from Kohat Research Station, Khyber Pakhtunkhwa.

At the conclusion of the training, Javed, direct of WRI Faisalabad, commended CIMMYT’s support and suggested continuing the pace of training. Dr. Tiwari stressed the importance of such efforts will help Pakistan’s scientists develop and deploy climate resilient, impactful wheat varieties to boost wheat production and reduce wheat imports in the country.

Bringing mechanization to farmers’ doorsteps

It is a winter morning in Ward 12 of Mutare Rural district in Zimbabwe. Farmers brave the cold weather to gather around several tents lined with a range of new agricultural machinery. The number of farmers increases, and the excited chatter gets louder as they attempt to identify the different machines on display. “That is a tractor, but it just has two wheels,” says one farmer. With enthusiasm, another identifies a multi-crop thresher and peanut butter machine and asks for the prices.

The scene typifies one of several settings for an awareness meeting conducted under the Feed the Future Zimbabwe Mechanization and Extension (Mechanization) Activity, funded by the United States Agency for International Development (USAID). The project operates in Zimbabwe’s Manicaland and Masvingo provinces and addresses the pressing need to improve farm power and machinery access for smallholder farmers in ten districts: Buhera, Chimanimani, Chipinge, Mutare rural, Bikita, Chiredzi, Chivi, Masvingo rural, Mwenezi and Zaka.

In recent years, farmers in the region have faced a decline in cattle populations due to tick-borne diseases—the devastating ‘January disease’ (Theileriosis) hitting hardest—causing significant draft power losses. In addition, on-farm and off-farm activities have notoriously been identified as labor-intensive, time consuming and back-breaking due to the level of effort required to execute certain tasks. Activities such as post-harvest processing have also been traditionally carried out by women, who are thus disproportionally affected by drudgery. Collectively, these challenges have affected not only food production and the quality of farm yields, but also drastically impacted farming families’ potential to realize sufficient household food and income security.

“Finding the best model of extension of appropriate machinery and developing financing mechanisms for smallholder farmers has been the work of previous projects on appropriate-scale mechanization,” says Christian Thierfelder, research director for the Mechanization Activity. “In this activity, we are implementing a service provider model in Zimbabwe and are aiming to reach 150 service providers and 22,500 users of these machines in the next two years.”

Despite previous successes under initiatives such as FACASI and R4/ZAMBUKO, there remains a huge demand for affordable machines that improve farm labor and generate income for smallholder farmers. “We already see hundreds of farmers demanding to mechanize agricultural activities in our intervention areas,” explains Leon Jamann, chief of party for the project. “That is why our activity aims to collaborate with banks and microfinance institutions to bank these farmers at fair rates so that they can buy the machinery that they need and want.”

A launchpad for success

The awareness meetings have served as launchpads to acquaint farmers with appropriate machinery right at the ‘farm gate’ while affording them a chance to explore the full range on offer. Since its inception, the Mechanization Activity has showcased through live demonstrations the operation and performance of machinery including the two-wheel tractor and trailer, ripper, basin digger, boom sprayer, multi-crop thresher, feed chopper-grinder, groundnut sheller and peanut butter machine. Each machine harmonizes with on-farm and off-farm activities, easing the labor burden and improving efficiency in land preparation, harvesting and post-harvest tasks. The aim is to create demand for and trigger business interest in the machinery through a service provision model.

The model centers on the service provider, typically an individual who owns machinery and extends their services to others for a fee. In some cases, organized Internal Savings and Lending (ISAL) and Production, Productivity Lending and Savings (PPL) groups have expressed, through the awareness meetings, interest in procuring a machine for use within the group. This symbiotic relationship empowers service providers economically, while granting communities access to crucial services that improve their land and labor productivity.

In the next step, service providers are then linked with banks to finance their machinery. This ensures a sustainable approach, as the mechanization solutions are locally produced, financed and used. Enhancing these local capacities and linkages is at the core of the activity and ensures impact beyond the project life cycle.

From awareness to demand

So far, a total of 32 awareness meetings have been held across three operational hubs in Masvingo and Manicaland provinces reaching 1,637 farmers—843 females and 794 males. The impact is evident, with 475 service providers identified across 20 implementation wards.

232 participants are keen to acquire a two-wheel tractor, with a further 191 opting for trailers, 63 for rippers, 125 for multi-crop threshers, 166 for chopper grinders, 178 for peanut butter machines and 31 for groundnut shellers. Among the prospective service providers are those opting to purchase a single unit while others are choosing two, three or more units from the machinery on offer.

Beyond the numbers, the Mechanization and Extension Activity continues to appeal to women and youth through sustainable and climate-smart intensification of crop production using conservation agriculture practices, opportunities for employment creation and enhancing profitability.

“I enjoyed learning about the service provider approach and learning about the machinery on display,” reflected Nyarai Mutsetse, a female farmer from Ward 12. “Other women even got the chance to try out the two-wheel tractor. From now on, we are going to save money in our groups and purchase some of these machines.”

Echoing the same sentiments, Patience Chadambuka was fascinated by the two-wheel tractor demonstration, and impressed that it could serve multiple purposes. “I can use it for different tasks—ferrying wood, land preparation and it can also help us raise money to take our children to school through service provision,” she said. “We are beginning to save the money, together with my husband because we would like to purchase the tractor and use it for our business.”

The Mechanization Activity awareness meetings paint a vivid picture of collaboration with other Feed the Future Zimbabwe Activities such as the Fostering Agribusiness for Resilient Markets (FARM), Resilience Anchors and Farmer to Farmer, among others. The activity harmonizes smallholder farmers with private sector enterprises, including machinery manufacturers, local mechanics, financial institutions and the Government of Zimbabwe. This collective cooperation is pivotal in helping smallholder farmers realize their mechanization business goals.

Year of millet: Why the renewed interest in the versatile grain

CIMMYT scientist Christopher Ochieng Ojiewo, who is responsible for strategic partnerships and seed systems in the dryland crops program, encourages Kenyans to adopt millet and related products. The move is seen as a crucial step in combating rising rates of obesity and improving nutrition in the country.

CIMMYT makes progress on some of the world’s top problems: 2022 Annual Report, “Harvesting Success”

CIMMYT targets some of the world’s most pressing problems: ending poverty, ensuring food for the future, mitigating climate change and improving the lives of farmers and consumers (especially women). CIMMYT is a CGIAR Research Center and has long been the world’s leading center for research on maize and wheat. This research capacity is being harnessed to achieve the crucial goals of climate resilience, and food and nutrition security.

Most of the world’s people depend on annual grain crops for their survival. Yet some of the world’s poorest men and women produce cereals. Annual grain farming has exacerbated climate change. The world’s great challenges of achieving climate resilience and nutrition security are being addressed by focusing CIMMYT’s research and development (R&D) on maize, and wheat, as well as on underutilized grain and legume crops.

Highlights from the 2022 Annual Report:

Annual cereal farming tends to release carbon into the atmosphere, while degrading the soil. Improving the soil takes years, and the high annual variation in weather demands long-term experiments. Field trials by CIMMYT over many years show that farmers can return carbon to the soil by using minimum tillage, rotating cereals with legumes, and by applying animal manure and strategic amounts of nitrogen fertilizer. As soil fertility improves, so do farmers’ yields.

Eleven million farmers in India alone produce maize, usually without irrigation, exposing families to climate-related disaster. Twenty new hybrids bred by CIMMYT out-perform commercial maize, even in drought years. One thousand tons of this heat-tolerant maize seed have now been distributed to farmers across South Asia.

Some wheat is rich in zinc and iron, which prevent anemia, especially in children. Yet naturally-occurring phytic acid in wheat blocks the body’s absorption of these minerals. A technique developed by CIMMYT lowers the cost of assaying phytic acid, so plant breeders in developing countries can identify promising lines of wheat faster. CIMMYT is also helping to reduce food imports by learning how other crops, like cassava and sorghum, can be blended with wheat to make flours that consumers will accept.

Some wheat hotspots are warm, dry, and subject to plant diseases. CIMMYT collaborates with plant breeders worldwide through the International Wheat Improvement Network (IWIN) to test promising new wheat lines in these tough environments. As more places become warmer and drier with climate change, CIMMYT and allies are developing wheat varieties that will thrive there.

Harvesting more maize in the future will depend on higher yields, not on planting more land. In plant breeding programs in Africa, South Asia and Latin America, CIMMYT and partners are already developing maize varieties and hybrids that will be released in just a few years. A review of these efforts reveals that annual yield increases will be about twice the rate achieved from 1973 to 2012.

Sorghum, millets, pigeon pea, chickpea and groundnuts have been favorite food crops in Africa for centuries. They are already adapted to warm, dry climates. CIMMYT is now working with national research programs to ensure that new crop varieties have the traits that male and female farmers need. Seed systems are being organized to produce more of Africa’s preferred crops.

Researchers can only breed new crop varieties if someone saves the old ones from extinction. CIMMYT does that with its world-class collection of wheat and maize seed. In 2022, CIMMYT’s two separate wheat and maize germplasm banks were combined into one. Modern techniques, such as vacuum-sealed seed packets and QR codes, allow rapid response to requests for seed from plant breeders around the world.

CIMMYT is helping Nepali farmers to plant maize in the lowlands, in the spring, when most land lies fallow. In 2022, CIMMYT provided training and investment to 2,260 farmers (35% women), who earned, on average, an additional $367 in one year. The added income allowed these farmers to invest in health care and schooling for their children.

Mexican farmers are saving money, harvesting more and selling their grain more easily. Some 4,000 farmers are now selling on contract to food manufacturing companies. The farmers lower production costs by using CIMMYT innovations in irrigation, fertilizer application and ecological pest control. Yields increase, the soil improves, and farmers find a ready market for their harvest.

The stories we have highlighted in this article are just some of the ones included in the Annual Report. See the full text of all the stories in “Harvesting Success” to learn how CIMMYT scientists are doing some of the most important research, for some of the world’s best causes.

Empowering women smallholder farmers in Africa with climate-resilient and nutritious maize varieties

In the vast landscapes of sub-Saharan Africa, where agriculture is the backbone of many communities, the quest for improved maize varieties is a vital step for ensuring food security in the face of climate change. Women, who represent approximately half the clients of maize breeding programs, have been essential in the realm of agricultural research. While significant gender-based differences in trait preferences exist in many African-staple crops, these appear less drastic in maize. However, there are gendered differences in management practices and productivity in maize-based systems.

Recognizing the need to bridge this gap, the CIMMYT-NARES (National Agricultural Research and Extension Systems) regional maize breeding networks in eastern and southern Africa have embarked on a transformative journey to empower farmers, especially women, through their innovative approach to maize breeding. The breeding networks are focused on ensuring smallholder farmers have access to a steady stream of climate-resilient and nutritionally enriched maize varieties that thrive in today’s stress-prone environments. To ensure these new maize varieties meet the needs of diverse users, including women, the breeding networks continue to adapt approaches to increase gender-responsiveness.

Linking science with the realities on the ground

Testing the performance of potential new maize hybrids coming from the breeding pipelines within farmers’ realities is critical to the ultimate success of these new varieties. In collaboration with over 400 farmers in southern Africa, the CIMMYT-NARES maize breeding network conducts extensive on-farm trials to evaluate the performance of these new maize varieties. A similar approach is adopted in eastern Africa. What sets these trials apart is the fact that over 40% of these trials are led by female plot managers. Farmers evaluate these varieties within the context of their own realities, including their own management practices, and provide valuable feedback to the breeding teams on the potential of new varieties.

By involving women in decision-making processes, CIMMYT-NARES networks ensure that their preferences and needs are considered when selecting the most promising hybrids for product advancement, announcement to partners, varietal releases and ultimately commercialization. This inclusive approach not only empowers women but also harnesses the collective knowledge and experience of the farming community. CIMMYT’s research recently showed that there is a relatively high degree of joint management within maize plots, and since 2022, the on-farm trials included a target of approximately 30% jointly managed plots.

Gender is only one axis of social difference that impacts agricultural production, variety selection, and end uses. Social differences including marital status, age, education level, ethnicity, wealth, access to capital, market access and livelihood orientation do play a role in the adoption of new varieties and farm productivity. By embracing the diversity within farming communities, CIMMYT-NARES networks are actively working towards understanding different farm types, while ensuring that the improved maize varieties are tailored to meet the diverse demands of the regions.

As the CIMMYT-NARES maize breeding networks continue to make innovative strides in breeding climate-resilient and nutritionally enriched maize varieties, they are not only transforming agriculture but also empowering individuals and communities. Through collaborative efforts, with the woman farmer at the heart of the approach, they are paving the way for a future where farming communities can thrive and contribute to food and nutritional security.

Transformative research provides pathways for including gender and socially marginalized groups

Intention, collaboration and commitment are critical to bridging the research and practice gap. Gender development practitioners and researchers from CGIAR centers, universities, national agricultural research and extension systems (NARES), civil society, and donor representatives this week shared insights from their research and work at the gender conference in New Delhi, India.

The discussion and exchange promises to create collaborations and opportunities devoted to improving the conditions and agency of women, youth and Indigenous communities in the Global South. “Transformative research can lead to meaningful impact,” said Angela Meentzen, senior gender researcher at CIMMYT. “We have been looking forward to this conference because coming together as researchers, scientists and development practitioners, we can discuss and share insights from each other’s practices and experiences from the field.”

Leading researchers and scientists from CIMMYT Asia and Africa presented their research and enriched the gender discussions at the conference. Meentzen said that CIMMYT is proud to support gender research that contributes meaningfully to transformative change and impact.

Below are highlights of four research poster presentations by our researchers (of the six presented by CIMMYT) at the conference:

Increased participation in agricultural processes does not mean more decision-making power for women farmers

Scientist Vijayalaxmi Khed examined how women manage excess workload (working inside and outside the house), a clear trade-off between productive and leisure time without change in domestic responsibilities. Due to domestic workload, she found that women’s time away from farms does not translate into leisure. Another important finding was that women with more agency had less time for leisure, unlike for men.

In her poster presentation, she concluded that rural women’s nexus of time poverty and decision-making has “clear implications for the development and diffusion of laborsaving technologies in agriculture.”

Working on the same study with Khed, Vijesh Krishna explored the relationship between women’s involvement in agricultural activities and decision-making. His presentation, ‘Farm managers or unpaid laborers?’, from the study covering 347 wheat-farming households across two years, concludes that “despite playing a crucial role in wheat farming in central India, most women lacked the ability to influence decisions.”

Gender-intentional maize breeding for better adoption and productivity in sub-Saharan Africa

Michael Euler, agriculture and resource economist, in his poster presentation explained how an on-farm trial to improve gender-intentional breeding and varietal adoption in maize was designed by CIMMYT breeders and researchers.

The study hypothesized that gender dynamics in household labor allocation and decision-making in maize systems influence trait preferences and farmers’ adoption of varieties. So, researchers conducted on-farm trials and household surveys with individual women and men household members to capture differences in their trait preferences in maize cultivation—production systems, seed demand and seed access—with 800 smallholder farmers in Zimbabwe and Kenya.

Euler emphasized the influence of socioeconomic and agroecological factors, including biotic–abiotic stress, in the household decisions on maize varietal adoption.

He concluded that the study results will help “guide the product development of regional maize breeding programs and strengthen communities’ adaptation to the changing environmental conditions for maize cultivation.”

Adoption of a weeding technology may lead to labor displacement of marginalized women laborers

Presenting a poster for the same session as Euler, Maxwell Mkondiwa—in a study coauthored with colleagues Khed and Krishna—highlighted how rapid diffusion of a laborsaving technology like herbicides could exclude the marginalized further. The study occurred in India’s state of Bihar, looking at nonfarming rural poor, primarily women, from socially marginalized groups.

From data on chemical weeding, the study analyzed the technology’s impact on inequality— highlighting how marginalized women laborers who work on manual weeding are then replaced by men who apply herbicides.

He stressed that not enough research is devoted to understanding whether farmer adoption of laborsaving technologies worsens economic inequalities or reinstates labor into better tasks. “We hope the evidence we generated will help researchers and policymakers develop relevant actions toward more inclusive innovations, and support laborers with new skills for the transitions,” said Mkondiwa.

Women exhibit limited technical knowledge and experience social benefits differently in male-headed households of CASI technology adoption

Emma Karki, in her poster, explained that there is limited knowledge of the impact of technology adoption on women in a male-headed household in South Asia—with decision powers generally resting with male household members. The research tried to understand the gendered differences in the evaluation of technology adoption in male-headed households using conservation agriculture-based sustainable intensification (CASI) technology as a case study.

The study focused on identifying the commonalities and differences in the experiences and evaluation of CASI technology. Results indicated that “despite technology adoption, women had limited mechanistic understanding compared to men, with similar limitations on women’s time use and capacity development,” said Karki.

For future CASI promotion, Karki concluded: “Reducing information gaps and incorporating technological preferences of women needs prioritizing, including creating opportunities for them to access knowledge and engage both men and women in critical discussions surrounding gender norms.”

Similarly, Moti Jaleta’s research presentation highlighted the challenges of mechanization adoption for smallholder farmers in Ethiopia, primarily women. “Intentional research, whether in gender or social development, helps identify problems and opportunities for change,” endorsed Jaleta.

Meaningful research helps achieve gender and social inclusion goals

The ‘From Research to Impact: CGIAR GENDER Impact Platform and ICAR Conference 2023’, between October 9-12, 2023, in New Delhi, gathered researchers from 68 countries. In her inaugural address at the conference’s opening, the President of India Smt. Draupadi Murmu affirmed, “For ecologically sustainable, ethically desirable, economically affordable and socially justifiable production, we need research which can enable conditions to reach these goals.”

At the end of the four-day conference—with 60 research presentations and six plenary sessions—the organizers and participants reflected on their resolve ‘From Research To Impact,’ and the promise to recognize and collectively address the gender and social inequities in agrifood systems development.

Community Business Facilitator: providing a service to farmers while increasing community access to nutritious food

Bhumi Shara Khadka is a 35-year-old community business facilitator who has made significant strides in agriculture and community development. Her journey began after completing training in sales skill development and technical capacity building for community business facilitators (CBF) organized by the Cereal Systems Initiative for South Asia (CSISA) in June 2022 and April 2023, respectively. This training opened up new opportunities, and she soon secured a job as a CBF. However, her ambitions didn’t stop there.

In February 2022, the Cereal Systems Initiative for South Asia (CSISA) recognized her potential and recommended her for a role as a community business facilitator with Laxmi Agrovet, a local agribusiness. To prepare for her new position, Ms. Khadka underwent additional training in various areas, including running sales meetings, farm mechanization, post-harvest handling and the fundamentals of sales and marketing. With these tools in hand, she set out to make a difference in the lives of farmers and the broader community.

To date, Khadka has conducted 97 sales meetings with farmer groups where she explains improved production methods, plant protection, post-harvest handling and how to market agriculture products effectively. She also demonstrates and sells Laxmi Agrovet agri-inputs such as seeds, fertilizer and tools. She gets a 20% commission on sales, bringing her an average net monthly income of NPR3,375 (US$26). Her role as community business facilitator also involves linking farmers with the local government agriculture program. As a result of her efforts, three farmers have each acquired a mini power tiller at a 50% subsidy.

Inspired by Khadka’s example, Chitra Bahadur Rokaya, acting director of the Agricultural Regional Directorate in Surkhet, Nepal, has expressed his desire to visit farmers and learn more about the activities of community business facilitators like Khadka during the technical capacity-building training to CBF in April 2023. Rokaya has expressed gratitude to trainees who attended the IPM training organized by CSISA and would visit the field sites of the trainees, if possible.

Khadka has also used her knowledge as a business facilitator and IPM trainee to establish her commercial vegetable farm, which, with her investment and CSISA’s technical support, now occupies five ropani (0.01 hectares). Her husband helps out and Bhumi sells the produce at local markets in Melkuna and Badichour, Surkhet, with traders often coming to the farm to buy from her directly. Last year, she earned NPR227,000 (US$1,733) of which her net income was NPR63,500 (US$485). Since starting the farm, the family’s food habits and those of her neighbors have changed for the better. Last year, the family kept a quarter of the vegetables she produced for their consumption, and she gave about 10% to neighbors.

Last year, under Khadka’s facilitation, 48 farmers cultivated vegetables on an average of 0.02 hectares each, each achieving an average net profit of NPR63,500 (US$485). Khadka also owns a power tiller, which she rents out for others to use, earning NPR35,000 (US$267) last year from this service provision activity.

In addition to her business and professional success, Khadka completed high school in 2014, underlining the significance of her accomplishments. Khadka’s remarkable journey is an inspiring agriculture success story, showcasing the transformative power of women empowerment in rural communities. Her dedication, knowledge and entrepreneurial spirit have improved farmers’ lives and elevated the entire community’s access to nutritious food. Her unwavering commitment to her work has brought her well-deserved recognition, and she is a beacon of hope for others in similar fields of endeavor.

Fostering agricultural innovation: collaborative meetings with NARC and NSSRC in Nepal

On October 4, 2023, Sieglinde Snapp, program director of the Sustainable Agrifood System (SAS) program, along with the country representative of CIMMYT and project lead of the Nepal Seed and Fertilizer Project (NSAF) Dyutiman Choudhary, visited the National Soil Science Research Center (NSSRC) under the Nepal Agricultural Research Council (NARC). The chief of NSSRC, Shree Prasad Vista, and his team welcomed Snapp and the team from CIMMYT. In the meeting, Vista presented an overview of NSSRC’s work and emphasized the collaborative work with NSAF. He focused on the achievements NSSRC has accomplished with the joint efforts of NSAF. He highlighted the launch of the Digital Soil Map and new fertilizer recommendations. He also reflected on the benefits of soil health cards to the farmers that NSAF supported. In addition, he prioritized the importance of collaboration to improve the livelihood of farmers. He appreciated the cross-learning that CIMMYT has been providing for knowledge transfer and adopting best management practices. After the meeting, the team visited the NSSRC’s laboratory, which provided insights about their soil research activities.

In sub-Saharan Africa, mineral fertilization and agroecology are not incompatible

Are agroecological approaches, based for example on the use of legumes and manure, enough by themselves to ensure a long-term increase in annual crop yields in sub-Saharan Africa (SSA), without using more mineral fertilizer?

The answer is no, according to a team of agronomists who have published an in-depth analysis of 150 scientific articles on annual crops (maize, sorghum, millet, rice, cassava, etc.) and tropical legumes, both annual grain legumes (cowpea, groundnut) and legume trees (acacia, sesbania) in tropical environments.

These publications collate 50 years of knowledge on nutrient balances in sub-Saharan Africa, biological nitrogen fixation by tropical legumes, manure use in smallholder farming systems and the environmental impact of mineral fertilizer.

“When we look at comparable climate conditions and physical soil constraints, yields of maize – the main source of calories for people – in sub-Saharan Africa are three to four times lower than elsewhere in the world. This is largely due to the fact that mineral fertilizer use (nitrogen, potassium) is on average four times lower there”, says Gatien Falconnier, a researcher at CIRAD based in Zimbabwe and lead author of the article. “On average, 13 kg of nitrogen are used per hectare and per year in sub-Saharan Africa, for all crops, bearing in mind that the poorest farmers have no access to nitrogen fertilizers and therefore do not use them. It is mainly agri-business and vegetable farmers that have access to fertilizers”, adds François Affholder, an agronomist at CIRAD based in Mozambique and co-author of the article.

“Our objective is not to produce like Europe or North America, but to produce more and more regularly according to the seasons and the years, and thus to increase the economic sustainability of our farming systems. To do so, we must ensure a minimum level of nutrients for crops, which require essential mineral elements for efficient photosynthesis, and therefore growth. Soils are typically lacking in mineral elements in sub-Saharan Africa, and the largely insufficient organic inputs lead to nutrient deficiencies in crops. This is the main limiting factor for crop yields, excluding drought situations”, says Pauline Chivenge of the African Plant Nutrition Institute (APNI). “The work by Christian Pieri showed as early as 1989 that it is possible to restore high levels of fertility to African soils through a balanced approach to organic and mineral nutrient inputs”, says François Affholder.

The article highlights five reasons why more mineral fertilizer is needed in sub-Saharan Africa:

  1. Farming systems are characterized by very low mineral fertilizer use, widespread mixed crop-livestock systems, and significant crop diversity, including legumes. Inputs of mineral elements to crops by farmers are insufficient, resulting in a widespread decline in soil fertility due to soil nutrient mining.
  2. The nitrogen requirements of crops cannot be met solely through biological nitrogen fixation by legumes and manure recycling. Legumes can only fix atmospheric nitrogen if symbiosis with soil bacteria functions correctly, which requires absorption of different mineral elements by the plant. Ken Giller of Wageningen University highlights that the ability of legumes to capture nitrogen from the air through their symbiosis with rhizobium bacteria is a fantastic opportunity for smallholder farmers, “but the amounts on nitrogen fixed are very small unless other nutrients such as phosphorus are supplied through fertilizers”.
  3. Phosphorus and potassium are often the main limiting factors of the functioning of plants and living organisms, including symbiotic bacteria: if there is not enough phosphorus and potassium in soils, then there is no nitrogen fixation. These nutrient elements, phosphorus, potassium and micro-elements, need to be provided by fertilizers, since they cannot be provided by legumes, which draw these elements directly from the soil. In the case of manure, this is simply a transfer from grazing areas to cultivated areas, which gradually reduces fertility in grazing areas.
  4. If used appropriately, mineral fertilizers have little impact on the environment. The greenhouse gas emissions linked to nitrogen fertilizer use can be controlled through a balanced and efficient application. In addition, mineral fertilizers can be produced more efficiently in order to reduce the impact of their production on greenhouse gas emissions, keeping in mind that this impact is low, at around 1% of total anthropogenic emissions.
  5. Further reducing mineral fertilizer use in SSA would hamper productivity gains and would contribute directly to increasing food insecurity and indirectly to agricultural expansion and deforestation. Producing for a population that will double by 2050 is likely to require the use of more agricultural land. An extensive strategy thus harms biodiversity and contributes to increasing greenhouse gas emissions, contrary to an agroecological intensification strategy combined with efficient and moderate mineral fertilizer use.

“If we take account of biophysical production factors, such as climate and soil, and shortages of land and agricultural workers, it will be impossible to reach a satisfactory production level by fertilizing soils only with manure and using legumes”, says Leonard Rusinamhodzi, an agricultural researcher at the Ghana International Institute of Tropical Agriculture.

However, “agroecological principles linked directly to improving soil fertility, such as recycling of mineral and organic elements, crop efficiency and diversity, with for example agroforestry practices and cereal-legume intercropping, remain essential to improve soil health. Soil fertility is based on its organic matter content, provided by plant growth that determines the biomass that is returned to the soil in the form of roots and plant residues. Efficient mineral fertilizer use starts a virtuous circle. These nutrients are crucial for the sustainability of agricultural productivity”, says Gatien Falconnier.

The researchers therefore argue for a nuanced position that recognizes the need to increase mineral fertilizer use in sub-Saharan Africa, in a moderate manner based on efficient practices, in conjunction with the use of agroecological practices and appropriate policy support. This balanced approach is aimed at ensuring long-term food security while preserving ecosystems and preventing soil degradation.

Breeding for the traits of tomorrow

Climate change poses a significant challenge to agricultural production and food security worldwide. “Rising temperatures, shifting weather patterns and more frequent extreme events have already demonstrated their effects on local, regional and global agricultural systems”, says Kevin Pixley, Dryland Crops Program director and Wheat Program director a.i. at CIMMYT. “As such, crop varieties that can withstand climate-related stresses and are suitable for cultivation in innovative cropping systems will be crucial to maximizing risk avoidance, productivity and profitability under climate-changed environments.”

In a new study published in Molecular Plant, scientists from CIMMYT, Alliance of Bioversity International and CIAT, the International Institute of Tropical Agriculture (IITA) and national agricultural research programs in Burkina Faso, Ethiopia, Nigeria, Tanzania and Uganda to predict novel traits that might be essential for future varieties of popular crops. Having surveyed nearly 600 agricultural scientists and stakeholders, they identify likely agronomic changes in future cropping systems seeking sustainability, intensification, resilience and productivity under climate change, as well as associated essential and desirable traits, especially those that are not currently prioritized in crop improvement programs.

Focusing on six crops which hold vital importance for African food security and CIMMYT and CGIAR’s mission—maize, sorghum, pearl millet, groundnut, cowpea and common bean—the authors review opportunities for improving future prioritized traits, as well as those they consider ‘blind spots’ among the experts surveyed.

Predicting future essential traits

The results of the study speak to the need for considering cropping systems as central to climate change resilience strategy, as well as the need to reconsider the crop variety traits that will eventually become essential.

Overall, experts who participated in the survey prioritized several future-essential traits that are not already targeted in current breeding programs — mainly water use efficiency in pearl millet, groundnut, and cowpea; adaptation to cropping systems for pearl millet and maize; and suitability for mechanization in groundnut. The survey confirmed that many traits that are already prioritized in current breeding programs will remain essential, which is unsurprising and consistent with other recent findings. While smarter and faster breeding for currently important traits is essential, the authors suggest that failure to anticipate and breed for changing needs and opportunities for novel characteristics in future varieties would be a big mistake, compromising farmers’ resilience, improved livelihood opportunities, and food security in the face of changing climate.

Importantly, the authors explain, the predicted future-essential traits include innovative breeding targets that must be prioritized. They point to examples such as improved performance in inter- or relay-crop systems, lower nighttime respiration, improved stover quality, or optimized rhizosphere microbiome, which has benefits for nitrogen, phosphorous and water use efficiency.

The authors emphasize that the greatest challenge to developing crop varieties to win the race between climate change and food security might be innovativeness in defining and boldness to breed for the traits of tomorrow. With this in mind, they outline some of the cutting-edge tools and approaches that can be used to discover, validate and incorporate novel genetic diversity from exotic germplasm into breeding populations with unprecedented precision and speed.
