Advanced training on conservation agriculture focuses on creating sustainable agronomic systems

CIMMYT-BISA-ICAR organized a two-week training program on conservation agriculture (CA) to demonstrate how CA can be a sustainable farming method and an effective tool for farmers and scientists in both irrigated and rainfed systems to manage agrifood system risks.

The training was jointly conducted by CIMMYT in collaboration with the Borlaug Institute for South Asia (BISA) and the Indian Council of Agricultural Research – Central Soil Salinity Research Institute (ICAR-CSSRI). It was held at the BISA research facilities in Jabalpur and Ludhiana, India, and ICAR-CSSRI in Karnal, India, from 9 December to 24 December 2023.

Creating resilient agrifood systems

Conservation agriculture is an ecosystem approach to agricultural land management based on three interrelated principles: minimal soil disturbance, permanent soil cover, and crop diversification. It helps farmers boost yields, regenerate natural resources, reduce cultivation costs, and create resilient production systems. This helps protect the environment and enhance livelihoods of rural populations, especially in the Global South.

In this region, the rural population depends on natural resources – land, freshwater, and coastal fisheries – for survival. However, the depletion of soil fertility, scarcity of water resources, exacerbated by environmental pollution and climate change-induced stresses, prove challenging to irrigated and dryland agriculture production systems. This puts agrifood systems in South Asia and Africa under tremendous pressure.

Despite the benefits, farmers face significant barriers to adopting CA practices. Lack of knowledge and skills, limited access to appropriate seeds and equipment, lack of policy support, under-developed value chains, and non-acceptance of the fact that CA can yield better results and long-term benefits often prevents farmers from adopting CA practices. Hence, capacity development is vital for the adaptation and scaling of CA-based technologies among smallholder farmers.

To cater to these needs, an Advanced Course on Conservation Agriculture in Asia – a Gateway for Sustainable and Climate Resilient Agrifood Systems was launched in 2010. Later, it was expanded to North Africa. The course links scientific advances and multidisciplinary approaches for upgrading the skills of participants for sustainable intensification and diversification of production systems, enhancing resilience, and conserving natural resources. Since its inception, this training series has directly benefited about 220 researchers, development personnel, and policymakers from 20 countries.

The 12th edition of the training in India saw mid-career researchers and development officers from Morocco, Egypt, Bangladesh, and India participate. Approximately 40% of the attendees were women.

Highlights from the India training program 

The inaugural session commenced on 9 December 2023 at the NASC Complex in New Delhi, India. Present at the opening ceremony were chief guest S.K. Chaudhari, deputy director general – Natural Resource Management, ICAR; Arun Joshi, CIMMYT regional representative and managing director of BISA; and Mahesh K Gathala, course coordinator, and Alison Laing, agroecologist from CIMMYT in Bangladesh.

During the welcome address, Joshi informed that CIMMYT and BISA are committed to capacity development of national partners around the world. Chaudhari emphasized the effectiveness in facilitating innovations in CA management. “Under increasing climate variability and change, the need to manage agronomic risks is even more significant and CA is an effective tool for farmers and scientists in irrigated and rainfed systems,” he said.

Participants were introduced to the genesis, background, and objectives of the course by Gathala. Resource persons across diverse disciplines informed the participants about innovative and cutting-edge research in all aspects of CA in both irrigated and dryland cropping systems, including advanced agronomy; mechanization; farm, soil, and water interactions; plant protection, health and crop breeding; climate resilience; farming systems simulation and analysis; agribusiness management; women’s empowerment and gender equity; and agricultural extension and out-scaling. Participants also gained practical knowledge and skills at the BISA research stations where extensive trainings were conducted under the guidance of Ravi Gopal Singh, Raj Kumar, and Lalit Sharma, course coordinators. They organized a series of sessions, along with the hands-on training, at the CA experiment farm in the BISA research facilities. Participants also toured 500 acres of farms at each of the locations. They visited farm facilities such as wheat research trials, molecular laboratory, precision nitrogen nutrition facility, seed processing unit, and farm machinery section.

The group also visited ICAR-CSSRI facilities in Karnal where R.K. Yadav, director, ICAR- CSSRI, welcomed the participants and highlighted the international and national collaboration activities at CSSRI and how long-term experiments on CA are managing and generating science-based evidence to inform policy and capacity building.

Special visits were organized to farm machinery manufacturers in the region to facilitate industry-participant interactions. Participants visited the Landforce factory at Amargarh, a leading manufacturer of all ranges of farm equipment – from seeding to harvesting and processing. This firm is equipped with the latest manufacturing facilities and techniques such as robotic welding, assembling and automated paint. Later, the group visited the National Agroindustry at Ludhiana, a top manufacturer of planters including bed planters, zero till drills, Happy Seeders, pneumatic and precise planters.

Finally, participants were taken to the farmer fields to interact with the farmers and observe the impact first-hand. They met with a progressive farmer group at Karnal who shared their experiences of practicing CA for the last few years. Post these visits and learning sessions, a closing ceremony was organized at CSSRI at Karnal which was chaired by R.K. Yadav and attended by special guests Rajbir Singh, ADG-ICAR and ML Jat, global director RFFS, ICRISAT. “The session on CA machinery was very helpful and carbon credit was an essential part of our learning. We also got an opportunity to exchange our ideas and experiences with researchers from Morocco, Egypt, and Bangladesh. We sincerely thank the organizers for making us confident and technically smart CA personnels,” said a participant from India.

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

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

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

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

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

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

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

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

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

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

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

Breaking barriers in agriculture

In Nepal, the International Water Management Institute and CIMMYT conducted research on Sustainable Intensification of Mixed Farming System (SI-MFS) in collaboration with local governments in Gurbakot Municipality of Surkhet and Haleshi Tuwachung Municipality of Khotang.

The research found a noticeable shift in farmers’ interest in farming practices, where successful implementation of innovation and scaling, it’s crucial to have farmers’ interest and ownership in interventions.

Conservation agriculture helps smallholder farmers to be more resource efficient

Millions of rural Indians, mostly farmers, are at the mercy of changing weather and climate change. Rising temperature and heat stress, unpredictable rainfall patterns, increasing drought-like situations, soil erosion and depleting water tables are leading to poorer yields and reduced income for farmers. While the agricultural sector and farmers are most affected by the adverse impacts of climate change, it is also one of the sectors significantly responsible for greenhouse gas emissions, contributing about 14% of the total greenhouse gas emissions in the country.

Good agronomy and soil management through conservation agriculture practices such as no-till farming, crop rotation, and in-situ crop harvest residue management are resource efficient and help reduce greenhouse gas emissions significantly. The intensification of these conservation agriculture practices by the Cereal Systems Initiative for South Asia (CSISA)—a regional project led by CIMMYT to sustainably enhance cereal crop productivity and improve smallholder farmers’ livelihoods in Bangladesh, India, and Nepal—and partners is helping smallholder farmers to improve their yield and income with less input costs.

Climate smart agriculture

Over 70% of Bihar’s population is engaged in agriculture production, with wheat and rice as the two major crops grown in the state. Bordering Uttar Pradesh, Buxar, is one of the many rural districts in Bihar, with over 108,000 hectares of land used for agriculture. The area is plain, fertile and has good irrigation facilities. The rice-wheat cropping system forms the dominant practice here, and pulses and other non-cereal crops are grown additionally during winters.

CSISA began promoting zero tillage in wheat cultivation in the area in 2010. Along with Krishi Vigyan Kendras (KVKs), and local agriculture departments, awareness and frontline demonstrations on different best management practices were conducted to inform farmers of alternative approaches to cultivating wheat and rice sustainably. Farmers were used to conventional farming methods, with more input costs and labor-intensive practices. In addition, as farmers were growing long-duration rice varieties, they typically sowed wheat in late November to early December, which meant harvesting in late April/May. Harvesting wheat this late caused yield losses due to terminal heat stress at the grain filling stage. With increasingly hot temperatures in recent years due to climate change, yield loss in wheat is imminent.

To help curb these yield losses, researchers and officials began promoting early sowing of wheat through a technology called zero tillage in the region, with sowing recommended before mid-November. As expected, this helped farmers to escape high temperature stress at the time of the dough stage, thus, saving grain shrinkage and yield loss at harvest. Zero tillage technology is a tested method with the potential to increase crop productivity through better time management and reduced input cost.

Deepak Kumar Singh, scientist at CSISA who has been supporting agri-extension efforts in the region for nearly a decade recalled how CSISA and partners were able to get more farmers on board with zero tillage and early wheat sowing:

“The best practices of zero till technology and early wheat sowing were encouraged widely through exposure visits, demonstration trials on progressive farmers’ fields, and providing support from local KVKs for machines and quality seeds, including the promotion of private service providers,” he said.

As more farmers were reached through field events, with visible on-field results during public harvest activities held at demonstration fields by CSISA and KVKs, the region gradually adopted early wheat sowing, zero tillage and direct seeded rice technologies. Currently, in the district, it is estimated that over 40% of wheat cultivation under the rice-wheat system is through zero till, helping farmers obtain better yield and profits.

Rice-wheat cropping systems, resilient and sustainable in increasingly changing climate

Rajapur, a small village in Buxar district, boasts 100% adoption of zero tillage in wheat cropping. We met farmer Rahul Rai whose family has been involved in farming for generations. The family owns over thirty acres of land with agriculture as the primary source of income. His father and his siblings were used to conventional farming methods. The produce from their farm was sufficient for household consumption and with the little extra left, they sold and made some income. On the significance of agriculture and farming for his family, Rahul Rai says, “this farmland has been feeding and supporting 17 members in our joint household.”

When young Rahul Rai got down to work in the family fields in the early 2000s, he was keen to explore possibilities to improve the income generated from the farm. Initially, like many others, he was engaged in intensive farming. According to Rai, “with the input costs rising daily, including scarce labor and soil health deterioration, bringing in some extra income seemed unsustainable”.

He first met researchers from the CSISA project and local KVK scientists in early 2011 in the neighboring village. The team was there to inform farmers about conservation agriculture practices and how to better manage yield and maintain soil health. Rai soon became more curious about the benefits of adopting these new methods over conventional practices. He started with a few acres with zero tillage and began sowing wheat by early November, as recommended by the scientists. In Rabi 2022-23, his wheat fields were sown by November 11, compared to the early years when the sowing date was around December.

With more participation and engagement with CSISA, in 2017, he joined other farmers from the region on an exposure visit to Patna organized by the CSISA-KVK network. In Patna, at the Indian Council of Agri Research – Research Complex for Eastern Region (ICAR-RCER), Rai and the visiting farmers were introduced to conservation agri-technologies for rice-wheat and other cropping systems. During the visit, they were informed about crop rotation and diversification, new seed varieties that are resilient and adaptable to changing climates, efficient use of plant protection chemicals and fertilizer and various subsidies from the center/state government to farmers. He later accompanied other progressive farmers on a CSISA-led travel seminar to Gorakhpur in 2017, where he observed acres and acres of wheat fields cultivated through zero tillage and early sowing that had yielded 6-7 tons per hectare (t/ha) on average.

At present, Rai’s family cultivates only zero till wheat in their fields and direct seeded rice on a few acres where irrigation facilities are well established. Rai asserts that until 2014, the wheat yield was about 10-15 quintals per acre (3.5-4 t/ha), rising to around 20-25 quintals per acre on average (5.5 t/ha in 2023) in recent years, thanks to conservation agriculture practices.

Today, the CSISA team has system optimization and demonstration trials on fields owned by Rai’s family where they conduct trials to demonstrate the importance and feasibility of different agri-practices and compare yields at harvest. Rai, a champion farmer who has been involved with CSISA for nearly a decade, said, “I am a collaborator with CSISA now. The data gathered from my fields on the compounding benefits of conservation agriculture technologies is used to promote the best practices and technology adoption across our district and state.”

One village at a time

Presently, Rajapur village has 100% zero tillage adoption. Despite most farmers being smallholders, this level of zero tillage adoption in wheat is impressive. Zero-till-based crop establishment, with appropriate diversification in crops grown, is economically beneficial and improves soil health. All these practices and technologies ensure lower greenhouse emissions and support climate change mitigation efforts. Above all, smallholder farmers are food secure and contributing in their small way to national and global food security.

To scale the adoption of conservation agriculture practices, CSISA and partners are collaborating with farmers in the district/state – many of whom are already 50-80% in zero tillage adoption. The team on the ground are conducting system optimization trials on farmers’ fields to generate data and evidence to support and strengthen policies and assist in integrating market intelligence to support access and availability of technology to all smallholders. Every year steadily, through a smallholder farmer, a village, a district, the effort is to slowly expand the area under conservation agriculture across the state and region and ensure increased system productivity and sustainability of agriculture.

A Mexican farm research program gains praise and interest for use abroad

Leveraging the leadership, science, and partnerships of the Mexico-based CIMMYT and the funding and research capacity of Mexico’s Secretariat of Agriculture and Rural Development (SADER) during 2010-21, the program known asMasAgro” has helped up to 500,000 participating farmers to adopt improved maize and wheat varieties and resource-conserving practices on more than 1 million hectares of farmland in 30 states of Mexico.

As a result of MasAgro research hubs operating across Mexico’s multiple and diverse agroecologies to promote the sustainable intensification of maize and wheat farming systems — including improved varieties and resource-conserving, climate-smart practices — yields of project participants for maize were 20% higher and for wheat 3% higher than local averages. Similarly, average net incomes for participating maize farmers were 23% greater and 4% greater for wheat farmers, compared to local averages.

The MasAgro biodiversity component gathered and analyzed one of the world’s largest-ever samplings of maize and wheat genetic diversity, including CIMMYT’s own vast seed bank collections, to help identify and characterize new genes of interest for breeding. As one result, more than 2 billion genetic data points and over 870,000 data entries from associated field trials are freely available to the scientific community, via the project’s online repository.

MasAgro has involved national and local research organizations, universities, companies, and non-government organizations working through more than 40 research platforms and 1,000 demonstration modules, while building the capacity of thousands of farmers and hundreds of technical and extension experts who serve them.

State-level partners sign on to MasAgro

Through MasAgro, CIMMYT entered into research and development partnerships with 12 Mexican states. An example is the mountainous, central Mexican state of Guanajuato, home to the El Bajío region, one of Mexico’s most productive farm areas but which also suffers from soil degradation, water scarcity, and climate change effects — challenges faced by farmers throughout Mexico. The governor of Guanajuato visited CIMMYT headquarters in Mexico in June 2023 to review progress and agree on follow-up activities.

CIMMYT has worked with Guanajuato state and local experts and farmers themselves to test and promote innovations through 7 research platforms reaching nearly 150,000 hectares. As of 2020, new crop varieties and resource-conserving, climate-smart management practices had helped underpin increases of 14% in irrigated wheat production and, under rainfed farming systems, improved outputs of 28% for beans, 150% for local maize varieties and 190% for hybrid maize, over state averages.

An integral soil fertility initiative has included the analysis and mapping of more than 100,000 hectares of farmland, helping Guanajuato farmers to cut costs, use fertilizer more effectively, and reduce the burning of crop residues and associated air pollution.

Service centers for the rental and repair of conservation agriculture machinery are helping to spread practices such as zero tillage and residue mulches. Supported by CIMMYT advisors, Guanajuato farmers are entering into equitable and ecologically friendly production agreements with companies such as Nestle, Kellogg’s, and Heineken, among other profitable and responsible public-private arrangements.

Acclaim and interest abroad for MasAgro

MasAgro has received numerous awards and mentions as a model for sustainable agricultural development. A few examples:

  • The Inter-American Development Bank (IDB) mentioned the program as an example of successful extension.
  • The Organization for Economic Cooperation and Development (OECD) cited MasAgro for promoting productive and sustainable agriculture.
  • The United Nations Development Program (UNDP) lauded MasAgro for promoting climate-resilient agriculture.
  • During the 2018 G20 summit in Argentina, MasAgro was considered a model for coordinating agricultural research, development, innovation, technology transfer, and public-private partnerships.
  • Bram Govaerts, now Director General of CIMMYT, received the 2014 Norman Borlaug Field Award for his work at the time as leader of MasAgro’s farmer outreach component.
  • MasAgro research hubs were recently used as a guide by USAID for efforts in Sudan and Eastern Africa. They have also been replicated in Guatemala and Honduras.

Moving out and beyond

In Central America and Mexico, the inter-connected crises of weak agri-food systems, climate change, conflict, and migration have worsened, while small-scale farmers and marginalized sectors remain mired in poverty.

Capitalizing on its experience in MasAgro, CIMMYT is a major partner in the recently launched CGIAR initiative, AgriLAC Resiliente, which aims to build the resilience, sustainability, and competitiveness of agrifood systems and actors in Latin America and the Caribbean, helping them to meet urgent food security needs, mitigate climate hazards, stabilize vulnerable communities, and reduce forced migration. The effort will focus on farmers in Colombia, El Salvador, Honduras, Mexico, Nicaragua, and Peru.

As described in a 2021 science journal article, CIMMYT also helped create the integrated agri-food system initiative (IASI), a methodology that was developed and validated through case studies in Mexico and Colombia, and leverages situation analysis, model predictions, and scenarios to synchronize public and private action toward sustainable, equitable, and inclusive agri-food systems.

“CIMMYT’s integrated development approach to maize system transformation in Mexico and Colombia laid the foundations for the IASI methodology by overcoming government transitions, annual budget constraints, and win-or-lose rivalries between stakeholders, in favor of equity, profitability, resilience and sustainability,” said Govaerts.

The 2021 Global Agricultural Productivity (GAP) report “Strengthening the Climate for Sustainable Agricultural Growth” endorsed IASI, saying it “…is designed to generate strategies, actions and quantitative, Sustainable-Development-Goals-aligned targets that have a significant likelihood of supportive public and private investment.”

New generation of farmers lead the way in making farming more productive and profitable

In the Indo-Gangetic Plains of northern India, nearly 70% of the population is involved in agriculture and extension services. Despite the abundantly fertile soil and farmers’ resilience, the adoption of agricultural innovations and productivity in the region has been slow.

This slow progress is often attributed to comparatively low levels of agricultural mechanization in the region and small land holdings of individual farmers, which often makes them risk averse to new technologies. However, times are changing.

Through the Cereal Systems Initiative for South Asia (CSISA) project, researchers from the International Maize and Wheat Improvement Center (CIMMYT), working closely with the local Krishi Vigyan Kendra (KVK) and partners, have led the transition from traditional farming to sustainable intensification agricultural practices in the region, helping the region slowly but steadily realize its full potential. Over the years, working extensively with progressive farmers, CSISA scientists have helped optimize the cost of inputs and increase productivity through new technology adoption and capacity building for these farmers.

Krishnamohan Pathak, a farmer in his early sixties from the village of Patkhaoli, first learned about conservation agriculture practices when he attended a field event in Nonkhar village in Deoria district, Uttar Pradesh. CSISA researchers invited farmers from Nonkhar and neighbouring villages to attend a field day event, an exposure activity, on zero tillage wheat and direct seeded rice (DSR) technologies. Zero tillage allows farmers to plant directly without plowing or preparing the soil, minimizing soil movement. Pathak was one of the farmers who got to see first-hand the advantages of these sustainable agricultural practices.

Seeing merit in these practices, Pathak continued to engage with CSISA scientists and in 2013-2014, adopted zero tillage, and directly seeded rice in his family-owned fields.

“The CSISA field team encouraged me to buy a rice planter which has helped manage paddy transplantation on time, and wheat after that through zero till,” Pathak said.

Pathak later participated in other agri-technology events and CSISA field trial activities. In 2018, he joined other progressive farmers from the region who attended a training at ISARC (IRRI South Asia Regional Centre) in Varanasi, Uttar Pradesh on direct seeded rice, organized by CSISA researchers to build capacity and raise awareness of the conservation agriculture method.

The next generation leads the way

Today, Pathak is one of the key influential farming members in the region. He has now, however, passed the baton to his 37-year-old son Gangesh Pathak. “I have occupied myself with other local leadership activities after my son has been active in the fields. I am not so skilled at using these machines, their maintenance and their services. The younger generation seems much better at adapting,” he said.

Gangesh has been involved actively in farming ever since he finished his graduation, trying to make it lucrative. He has enjoyed recent success growing wheat and rice through new technology and practices. Standing in the fields recently harvested with the new improved wheat variety DBW 187, grown through early sowing – a method which goes against the traditional practice of planting after November – and zero tillage, he is happy with his 5.5 ton per hectare yield.

He spoke enthusiastically about the farming machinery he has procured to reduce drudgery in his farms and the hiring services provided to smallholder farmers in the region. After his father bought the transplanter in 2014, the family added larger machines such as the Happy Seeder, Super Seeder, Laser Land Leveller, Straw Reaper, and Direct Seeded Rice machine.

According to Gangesh, this has been possible thanks to the support from the local agriculture authorities and guidance from the CSISA team, who told his father about the various schemes offered by the central and state government to support farmers to adopt more productive and sustainable agricultural technologies.

Ajay Kumar Pundir, CIMMYT agronomist, based in Uttar Pradesh and leading CSISA’s efforts, stressed the importance of access to agricultural mechanization and support.

“Our job just does not end at informing and training farmers about better-bet agricultural practices. Along with other public and private stakeholders, we must support and ensure their availability and access – machines, quality seeds, timely information – for farmers to adopt it,” he said.

Custom hiring center help scale mechanization

With so much farm machinery, the Pathaks soon began extending hiring services. Custom hiring is a promising enterprise opportunity for farmers as they can use the machinery on their farms and earn extra income by extending services to other farmers at a reasonable cost, which helps cover diesel and maintenance costs. Gangesh made about 2.5 lakhs (USD $3,033.76) in profit during the 2022-2023 Rabi (winter crops) through hay machine hiring services, where around 250 farmers used these services.

Once the word spread, demand for hiring services by smallholder farmers, challenged by scarce labor for sowing and harvesting, started growing. Gangesh was encouraged by the good profits and was keen to share the benefits of such hiring services to as many farmers as possible, and he helped establish a Farmer Producer Organization (FPO) with his father, Krishnamohan. FPO is a group made up of farmer-producers who are entitled to a host of benefits, including quality seeds, technical support, market access, under the Department of Agriculture and Farmers Welfare (DA&FW).

The FPO, started by the Pathaks in 2020, with 75 members (farmers) initially, currently boasts of around 300 farmers. Almost all FPO members have availed the custom hiring services for all farming purposes and various crops. Farmers, “particularly smallholders who cannot afford to purchase these machines for less than a few acres of land, are happy with the custom hiring services. It helps reduce their input cost by almost 50% along with other FPO member benefits,” Gangesh said.

Community-based technology demonstrations by CSISA and KVK and partners are ongoing to scale-out proven technologies and practices like early wheat sowing, zero tillage, and direct seeded rice. Gangesh is hopeful that farmers in the region, despite the emerging climate crisis concerns – already being felt in the region – can produce more and improve their income. He reckons that diversifying between rice-wheat cropping systems, mechanizing and system optimization through better advisories, and improved access to technologies as recommended by agronomists, will help farmers stay ahead of the curve.

Weaving bonds of trust to generate changes

Following a period of continuous interaction, the researchers identified not only a number of shared challenges in their respective countries, but also how much complementary and concrete opportunities for teamwork are created when bonds of trust and teamwork are strengthened.

“In addition to strengthening knowledge, there’s also the relationship between researchers and institutions, understanding the role of each member of the team is important and allows us to make greater progress,” said Atencio. “For example, Alicia works on improvement, Ana on the use of bio-inputs, and Karen on transfers and linking. We all see that there are opportunities in agriculture for innovation by using tools such as e-agrology. The result of this is that generational change is becoming more and more urgent.”

Proposing more ambitious projects, but also clearer and more precise ones, is part of the learning the researchers plan to take with them. The scientists are determined to share this information with their teams and colleagues, along with integrative approaches that are designed to strengthen the human talent of each institution.

“In Ecuador, we practice the agriculture of conservation, but we didn’t know the concept of not removing the soil,” Picay said. “It is always a good decision to invest in training, as it refreshes the thought, opens the mind and triggers actions.”

The TechMaíz project will continue in 2023 with its third year of implementation, promoting national meetings to promote and disseminate the use of sustainable technologies for maize production. CIMMYT training for members of the Latin American Maize Network is also expected to continue.

A reluctant farmer changes the fortune of his inherited land

In the sultry spring-summer heat of Bihar, India, the landscape is yellow with wheat grains ready for harvest. Here, in Nagma village farmer Ravi Ranjan attends to his fields — mostly wheat, with some pulses in the adjoining plots. The harvest this year will be a little less than anticipated, he explains, as receding monsoon rains left the soil too moist to begin sowing on time.

Ranjan’s grandfather and father were both farmers who owned sizable land. His father used to say that the land was productive but required a lot of hands, sweat, and time to sustain the yields. Agriculture was all that the family had known and depended on for decades before Ranjan’s father left the sector for the civil service. After the early demise of his grandfather in 2003, and with his father in a secure government job, it fell to Ranjan to shoulder the responsibility of managing the family farm.

As a young man, Ranjan had sometimes helped his grandfather in the fields, but now, as the owner of a hydraulic mechanical service firm working hundreds of kilometers away in Chhattisgarh, he had never imagined becoming a farmer himself. Though reluctant to begin with, Ranjan decided there was no alternative but to take on the challenge and do his best, and while initially he had little success with the new venture, slowly and steadily he began to change the fortune of his inherited land.

Today Ranjan is one of the local area’s success stories, as a progressive and influential farmer with ties to the Cereal Systems Initiative for South Asia (CSISA) project. Researchers on the CSISA team have been working with farmers like him in the region for over a decade and are proud of the ongoing collaboration. Ranjan’s fields are regularly used as CSISA trial plots to help demonstrate the success of new technologies and conservation agriculture practices that can enhance productivity and sustainability. For example, in the 2021-2022 winter cropping season — locally known as Rabi — he harvested 6.2 tons per hectare – while a separate acre plot as demonstration site was harvested publicly with officials from CSISA and the Krishi Vigyan Kendra Network (KVK), JEEViKA, and farmers from neighboring villages for improving yield sustainably.

As India celebrates Kisan Diwas (Farmer’s Day) on December 23, we speak to Ranjan about his hopes for the future and the continuity of farming in his family after he hangs his boots.

Farming has seen a sea of change since your grandfather’s time. What do you think has been the most transformative change in the years you have been involved in farming?

I think using mechanized tools and technology to ensure good cropping practices has tremendously reduced manual work. Furthermore, today with innovations and digitization in agriculture science, farming is not just recognized as a noble profession, but also an enterprising one. I am happy I came into it right when things were changing for good. I have no regrets.

Though not by choice that I came into it, I am now fully invested and devoted to farming. From being an entrepreneur to farming, it has been a transformational journey for me. I am unsure whether my daughters — I have three, the eldest turns 18 next year — will choose to be involved in agricultural farming. But I will encourage and fully support them if they choose to take it up. After all, they will inherit the land after me.

Extreme climate effects are challenging agricultural practices and output. How are you preparing to reduce the impact of these in your fields?

It is worrying to see how extreme climatic effects can be challenging for agriculture, particularly for smallholder farmers in the region. Erratic rains, drought at times, and increasing temperatures have all harmed our cereal and vegetable farms and affected yield in wheat crops significantly. The adoption of new technologies like direct seeded rice (DSR) to avoid puddled rice transplanting, early wheat sowing (EWS) to avoid terminal heat at maturity, zero tillage technology (ZTT), and better-quality seeds, are interventions introduced and supported by CSISA and other agricultural organizations from the state that has helped combat some of these climate-induced problems.

In my own fields, I have also introduced proper irrigation systems to reduce the impact of limited water availability. I hope to stay ahead of the curve and make sure I am aware of all that is possible to keep my farm productive and sustainable.

How did you begin your association with CSISA? What has been your experience of working with them to make your agriculture resilient and productive?

I was initially approached by one of their scientists working in the area. And because of my interest, they slowly began informing me of various technologies I could try. With these technologies implemented in my field, the yield and productivity improved.

Soon after expanding my agriculture output, I got 50 acres of land on lease in the village to grow more crops like pulses, along with rice and wheat. Today, CSISA has started using my fields as their demonstration plots for new technologies and best practices, and to spread awareness and bring in more farmers from neighboring villages to encourage adoption.

CSISA and others call me a progressive and innovative farmer. I am proud that many farmers and other agricultural agencies in the area have appreciated our efforts to continue making agriculture productive and sustainable.

About CSISA:

Established in 2009, the Cereal Systems Initiative for South Asia (CSISA) is a science-driven and impacts-oriented regional initiative for increasing the productivity of cereal-based cropping systems. CSISA works in Bangladesh, India, and Nepal. CSISA activities in India focus on the eastern Indo-Gangetic Plains, dominated by small farm sizes, low incomes, and comparatively low agricultural mechanization, irrigation, and productivity levels.

Sustainability of rice production in the Northwestern Indo-Gangetic Plains

Rice is a vital crop for India, contributing around 30 percent of calories consumed in the country and providing a crucial source of income from exports. However, due to climate change and conversion of land for other uses, rice growing area in India is projected to decline by 6-7 million hectares (ha) by 2050, while production must increase by 1.1% annually over the next four decades to achieve rice self-sufficiency for the country.

As there is limited opportunity to horizontal expansion of cultivable land, the predicted increase in demand must be met through increasing rice yields in regions with low yields and maintaining existing yields in high-yielding areas. This must be achieved using sustainable farming practices: currently, 90 percent of total greenhouse gas (GHG) emissions of monsoon season cropped cereals in India is caused by rice cultivation, as is 80 percent of the energy and water used in agriculture.

Scientists found that in the Northwestern Indo-Gangetic Plains (IGP) of India, yield gaps were small (ca. 2.7 t ha−1, or 20% of potential yield) mainly because of intensive production system with high input use. Using management data from 4,107 individual farmer fields, the study highlighted scope to reduce nitrogen (N) inputs without compromising yields in this intensive production system.

Findings show evidence of and methodology for the quantification of yield gaps and approaches that can improve resource-use efficiency, providing a possible alternative approach that could be reproduced elsewhere for other crops and contexts. It is recommended that future research focuses on ways to reduce other production inputs without compromising the yields in such intensive production systems.

This paper is the result of Harishankar Nayak’s PhD training in collaboration with the Indian Council of Agricultural Research (ICAR) jointly supervised by the researchers at the Indian Agricultural Research Institute (IARI) and International Maize and Wheat Improvement Center (CIMMYT).

Zambia officials promote sustainable maize cropping practices for small-scale farmers

For the first time in Zambia, a special Ministry of Agriculture committee has endorsed innovative sustainable intensification practices to diversify maize-based farming systems and boost the food and nutritional security of millions of small farm households, while enriching depleted soils.

Zambia’s recently formed “National Advisory Committee for the Approval/Validation of Candidate Technologies or Agronomic Practices” approved in September the release to farmers of three new systems for better yields and soil maintenance: growing maize between “hedge-rows” of legume trees; or in rows side-by-side with grain legumes as strip crops; or on permanent, raised soil beds or ridges.

Legume trees and grain legumes enhance soil nitrogen and organic matter content, and legume grains themselves are a valuable, alternative food, rich in protein for rural households. Raised soil beds and ridges can keep soils oxygenated and productive when heavy rainfall floods the fields, as can often occur in northern and northwestern Zambia.

All three systems can be bundled with conservation agriculture approaches, which are based on the principles of minimum soil disturbance, keeping crop residues on the soil, and growing a more diverse selection of crops.

The improved maize cropping methods are a research outcome of the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project, a partnership involving the Food and Agriculture Organization (FAO) of the United Nations, Zambia’s Ministry of Agriculture (MoA), and the International Maize and Wheat Improvement Centre (CIMMYT), with funding from the European Union (EU) and building in part on other results in Africa, including the Feed the Future-Africa Research in Sustainable Development for the Next Generation (Africa RISING) initiative.

“The official clearing of these transformative cropping technologies is a huge milestone for the project and for Zambia’s resource-poor farmers,” said Christian Thierfelder, CIMMYT principal cropping systems agronomist based in southern Africa who, as part of SIFAZ, is testing and disseminating maize cropping practices that boost harvests, enrich soils, and capture and conserve moisture. “We’re working closely with Zambia’s MoA and the FAO, planning research trials, demonstrations and promotion to reach 20,000 farmers as a first step.”

An essential crop

Maize is the number-one food staple in sub-Saharan Africa, sown by some 300 million smallholder farmers using seasonal rains. A leading crop as well for Zambia’s small-scale, subsistence, and often impoverished farmers, maize grows poorly in extreme heat, infertile soils, and extended dry weather. Failed maize crops can bring hunger to smallholders and their families, for whom risks are high and formal safety nets are non-existent.

The EU recently announced that it will provide an additional EUR 20 million in funding for SIFAZ, now three years old and operating in five provinces and 27 districts of Zambia.

The cropping practices submitted to the National Advisory Committee by Thierfelder and his colleagues conform to a sustainable intensification assessment framework developed by the Feed the Future Innovation Lab for Collaborative Research on Sustainable Intensification of the US Agency for International Development (USAID) and Kansas State University.

“The framework provides a set of indicators for evaluating technologies according to their effects on productivity, economics, the environment, and social and human conditions — domains considered essential for sustainable agriculture systems,” Thierfelder explained. “The framework is well suited for smallholder farm settings, where agriculture is linked to development goals such as alleviating poverty, avoiding land degradation, increasing food and nutrition security, and supporting women’s empowerment.”

From seed to feed

Experts at the International Maize and Wheat Improvement Center (CIMMYT) are working with partners to drive self-sufficiency in poultry feed and achieve more sustainable maize systems in Nepal thanks to the Nepal Seed and Fertilizer (NSAF) project.

About 3,000 metric tons (t) of poultry feed is used in Nepal every day, with maize making up about half of feed ingredients. The Feed Association of Nepal estimates that more than 80% of maize for animal feed requirements are met through imports, which costs around $100 million a year. Maize imports are estimated to exceed $130 million in 2022.

Through the NSAF project — a project which facilitates sustainable increases in Nepal’s national crop productivity, income and household-level food and nutrition security across 20 districts — CIMMYT scientists have been supporting public private partnerships to increase commercial maize production and strengthen the “seed to feed” chain in the country.

In the Terai region, huge swaths of land lie fallow in the spring season. Experts estimate that enough maize grain could be produced on this land to substitute about 40% of maize imports to the country. Increasing spring maize production in these fallow lands has been one of the goals of the NSAF team, as well as improving coordination between public and private sectors. To do this, the team have designed a multi-stakeholder engagement initiative to strengthen the seed to feed chain.

In December 2020, CIMMYT experts began the initiative to scale up the use of new maize hybrid varieties and improved agronomic practices. In the spring of 2022, CIMMYT researchers partnered with public and private organizations in Banke, Bardiya and Kailali to help commercialize hybrid maize production and strengthen maize value chain coordination in the region. Partners included integrated agriculture and livestock development offices in Bardiya, agriculture knowledge centers in Banke and Kailali, local governments, farmer cooperatives, seed companies, agro-dealers and feed mills.

Working with these partners, CIMMYT scientists also advanced efforts to improve the capacity of actors to increase efficiency in supply chains, production and marketing, provide local employment and strengthen the market for domestically produced maize for poultry feed.

As of September 2022, the following milestones have been achieved:

  • Provincial governments have established multi-stakeholder maize commercial networks at sites where maize actors and stakeholders participate to coordinate commercial maize production, access to support services and to link farmers and grain buyers.
  • In 2022, more than 2,000 households from 19 local government units produced maize on 547 ha in Banke, Bardiya and Kailali. The total maize production increased from 1390t in 2021 to 3,232t in 2022. This was an increase of 61% in the number of farmers and 52% in area. The value of maize sold also tripled from USD 306,900 in 2021 to USD 915,700 in 2022.
  • The farm gate price of maize by 22% and the Government of Nepal invested $2.37 million to support access to quality seed, agriculture machinery and irrigation facilities.
  • Farmers sold 500t maize grains to feed mills in 2022, a huge jump from only 30t in 2021.
  • In partnership with the Government of Nepal, CIMMYT researchers organized training programs for farmers in maize commercial network sites on production, post-harvest, exposure visits and marketing to prepare them to produce maize as per buyers’ requirements. They also guided farmers on how to access credit, crop insurance, and digital advisory services to further improve their production and marketing.

Next steps

CIMMYT scientists plan to double the number of districts under the maize commercialization model from three to six in 2023. The Department of Agriculture under the Ministry of Agriculture and Livestock Development, and the local and provincial governments are keen to scale out the model to several maize production regions of Nepal.

In a joint assessment with the Government of Nepal and private sector partners, CIMMYT scientists identified a number of key areas for further development. These include supporting farmers to access high yielding, short duration and stress tolerant maize varieties, as well as best management practices for improving maize production. Other priorities include developing models for contractual arrangements between farmers groups and feed mills, encouraging public and private sector investment in village-level warehouses with drying facilities. Finally, CIMMYT and partners are eager to introduce incentives such as subsidies on grain produced and sold by farmers through cooperatives, develop national maize quality standards and update the 1976 Feed Act.

Going forward, CIMMYT’s research on public private partnership for commercial maize production will focus on drivers of uptake of technology and institutional innovations, the role of aggregation models and contractual arrangements in maize market system coordination and impact assessment on farmers benefits.

Getting to win-win: Can people and nature flourish on an increasingly cultivated planet?

Our planet is facing a massive biodiversity crisis. Deeply entwined with our concurrent climate crisis, this crisis may well constitute the sixth mass extinction in Earth’s history. Increasing agricultural production, whether by intensification of extensification, is a major driver of biodiversity loss. Beyond humanity’s moral obligation to not drive other species to extinction, biodiversity loss is also associated with the erosion of critical processes that maintain the Earth system in the only state that can support life as we know it. It is also associated with the emergence of novel, zoonotic pathogens like the SARS-CoV-2 virus that is responsible for the current COVID-19 global pandemic.

Conservation ecologists have proposed two solutions to this challenge: sparing or sharing land. The former implies practicing a highly intensive form of agriculture on a smaller land area, thereby “sparing” a greater proportion of land for biodiversity. The latter implies a multifunctional approach that boosts the density of wild flora and fauna on agricultural land. Both have their weaknesses though: sparing often leads to agrochemical pollution of adjacent ecosystems, while sharing implies using more land for any production target.

In an article in Biological Conservation, agricultural scientists at the International Maize and Wheat Improvement Center (CIMMYT), argue that, while both land sharing and sparing are part of the solution, the current debate is too focused on trade-offs and tends to use crop yield as the sole metric of agricultural performance. By overlooking potential synergies between agriculture and biodiversity and ignoring metrics that may matter more to farmers than yield —for example, income, labor productivity, or resilience — the authors argue that the two approaches have had limited impact on the adoption by farmers of practices with proven benefits on both biodiversity and agricultural production.

Beyond the zero-sum game

At the heart of the debate around land sparing versus land sharing is a common assumption: there is a zero-sum relationship between wild species density and agricultural productivity per unit of land. Hence, the answer to the challenge of balancing biodiversity conservation with feeding a growing human population appears to entail some unpalatable trade-offs, no matter which side of the debate you side with. As the debate has largely been driven by conservation ecologists, proposed solutions often approach conserving biodiversity in ways that offer limited benefits, and often losses, to farmers.

On the land sparing side, the vision is to carve up rural landscapes almost as a planner would zone urban space: some areas would be zoned for highly intensive forms of agricultural production, largely devoid of wild species, while others would be zoned as biodiversity-rich areas. As the authors point out, however, such a strictly segregated view of land use is challenged by the natural migratory patterns of species, their need for diverse types of ecosystems over the course of the seasons or their lifecycles, and the high risk of pollution associated with intensive agriculture, such as run-off and leaching of agrochemicals, and pesticide drift.

Proponents of the land sharing view argue for a multifunctional approach to agricultural production that introduces a greater density of wild species onto agricultural land, thus integrating production and conservation into the same land units. This, however, inevitably diminishes agricultural productivity, as measured by yield.

This view, the article argues, overlooks the synergies between agriculture and biodiversity. Not only can biodiversity support agriculture through ecosystem services, but farmlands also support many species. For example, the patchiness created in the landscape by swidden agriculture or by grazing livestock supports more biodiversity than closed-canopy ecosystems, benefiting open-habitat species in particular. And except for rare forms of “controlled environment agriculture” such as hydroponics, all agricultural systems depend on the ecosystem services rendered by a multitude of organisms, from soil fertility maintenance to pollination and pest control.

“Agriculture is about flexibility and pragmatism,” said Frédéric Baudron, a system agronomist at CIMMYT and the lead author of the study. “Farmers need to be presented with a wider basket of solutions than the dichotomy of high-yielding and polluting agriculture versus low-input and low-yielding agriculture offered by land sharing/sparing. Virtually all production systems require both external inputs and ecosystem services. In addition, agricultural scientists have developed a variety of solutions, such as precision agriculture, to minimize the risk of pollution when using external inputs, and push-pull technology to harness ecosystem services for tangible productivity gains.

Similarly, an exclusive focus on yield as a measure of agricultural performance obscures ways in which greater biodiversity on agricultural land can support farmers’ livelihoods and economic wellbeing. The authors show, for example, that simplified landscapes in southern Ethiopia tend to have higher crop productivity. But more diverse landscape in the same area, while hosting more biodiversity, produce more fuelwood, support a higher livestock productivity, provide a greater dietary diversity, and are more resilient to environmental stresses and external economic shocks, all of which being highly valued by local people.

Imagining landscapes where biodiversity and people win

The land sharing versus sparing debate deserves enormous credit for bringing attention to the role of agriculture in biodiversity loss and for pushing the scientific community and policymakers to address the problem and think about how to balance agriculture and conservation. As the authors of this paper show, as researchers from a more diverse range of scientific disciplines join the debate, there is tremendous potential to move the conversation from a vision that pits agriculture against biodiversity and towards solutions that highlight the potential synergies between these activities.

“It is our hope that this paper will stimulate other agricultural scientists to contribute to the debate on how to feed a growing population while safeguarding biodiversity. This is possibly one of the biggest challenges of our rapidly changing agri-food systems. But we have the technologies and the analytics to face this challenge,” Baudron said.

Bending gender norms: women’s engagement in agriculture

Researchers at the International Maize and Wheat Improvement Center (CIMMYT) have studied and witnessed that women, particularly in South Asia, have strongly ingrained and culturally determined gender roles.

While women play a critical part in agriculture, their contributions are oftentimes neglected and underappreciated. Is there any way to stop this?

On International Day of Women and Girls in Science, we spoke to Pragya Timsina about how women’s participation in agriculture is evolving across the Eastern Gangetic Plains and her findings which will be included in a paper coming out later this year: ‘Necessity as a driver of bending agricultural gender norms in South Asia’. Pragya is a Social Researcher at CIMMYT, based in New Delhi, India. She has worked extensively across different regions in India and is currently involved in various projects in India, Nepal and Bangladesh.

What is the current scenario in the Eastern Gangetic Plains of South Asia on gender disparities and women’s involvement in agriculture? Is it the same in all locations that your research covered?

Currently, traditional roles, limited mobility, societal criticism for violating gender norms, laborious unmechanized agricultural labor, and unacknowledged gender roles are among the social and cultural constraints that women face in the Eastern Gangetic Plains. Our research shows that while these norms exist throughout the Eastern Gangetic Plains, there are outliers, and an emerging narrative that is likely to lead to further bending (but not breaking, yet) of such norms.

Are there any factors that limit women from participating in agriculture? 

Cultural and religious norms have influence gender roles differently in different households but there are definitely some common societal trends. Traditionally, women are encouraged to take on roles such as household chores, childcare, and livestock rearing, but our research in the Eastern Gangetic Plains found that in specific regions such as Cooch Behar (West Bengal), women were more actively involved in agriculture and even participated in women-led village level farmers’ groups.

How or what can help increase women’s exposure to agricultural activities?

At the community level, causes of change in gender norms include the lack of available labor due to outmigration, the necessity to participate in agriculture due to a labor shortage, and a greater understanding and exposure to others who are not constrained by gendered norms. There are instances where women farmers are provided access and exposure to contemporary and enhanced technology advances, information, and entrepreneurial skills that may help them become knowledgeable and acknowledged agricultural decision makers. In this way, research projects can play an important role in bending these strongly ingrained gendered norms and foster change.

In a context where several programs are being introduced to empower women in agriculture, why do you think they haven’t helped reduce gender inequality?

Our study reveals that gender norms that already exist require more than project assistance to transform.

While some women in the Eastern Gangetic Plains have expanded their engagement in public places as they move away from unpaid or unrecognized labor, this has not always mirrored shifts in their private spaces in terms of decision-making authority, which is still primarily controlled by men.

Although, various trends are likely to exacerbate this process of change, such as a continued shortage of available labor and changing household circumstances due to male outmigration, supportive family environments, and peer support.

What lessons can policymakers and other stakeholders take away to help initiate gender equality in agriculture?

Although gender norms are changing, I believe they have yet to infiltrate at a communal and social level. This demonstrates that the bending of culturally established and interwoven systemic gender norms across the Eastern Gangetic Plains are still in the early stages of development. To foster more equitable agricultural growth, policymakers should focus on providing inclusive exposure opportunities for all community members, regardless of their standing in the household or society.

What future do the women in agriculture perceive?

Increasing development projects are currently being targeted towards women. In certain circumstances, project interventions have initiated a shift in community attitudes toward women’s participation. There has been an upsurge in women’s expectations, including a desire to be viewed as equal to men and to participate actively in agriculture. These patterns of women defying gender norms appear to be on the rise.

What is your take on women’s participation in agriculture, to enhance the desire to be involved in agriculture?

Higher outmigration, agricultural labor shortages, and increased shared responsibilities, in my opinion, are likely to expand rural South Asian women’s participation in agricultural operations but these are yet to be explored in the Eastern Gangetic Plains. However, appropriate policies and initiatives must be implemented to ensure continued and active participation of women in agriculture. When executing any development projects, especially in the Eastern Gangetic Plains, policies and interventions must be inclusive, participatory, and take into account systemic societal norms that tend to heavily impact women’s position in the society.

Decomposing maize yield gaps to better inform policy and public investments

In sub-Saharan Africa, smallholder production is characterized by low agricultural productivity which is often cited as a major factor of  food insecurity in the region. Recent research from multiple countries in the region suggests that average maize yields of around 1.7 t/ha in 2010 must increase to 6.8 t/ha to meet estimated demand in 2050. To achieve this, per-hectare maize output must grow by about 3.5% per year. Although addressing this challenge seems daunting, estimates suggest that such high yields are technically feasible. However, a shared understanding of the investments and policies required remain elusive.

Under the Taking Maize Agronomy to Scale in Africa (TAMASA) project, scientists from Wageningen University and the International Maize and Wheat Improvement Center (CIMMYT) conducted research on this question, using uniquely detailed farm surveys which provide integrated information about smallholders’ agronomic practices and farm management, soil health and other biophysical characteristics, as well as socioeconomic and other characteristics of farm households.

Decomposing yield gaps

Yield gaps for rainfed crops are defined as the difference between the water-limited yield potential and the actual yield observed in farmers’ fields. One framework to explain yield gaps decomposes the yield gap into efficiency, resource and technology components (Figure 1).

The study disaggregated maize yield gaps in Ethiopia based on field level and farming systems information (Figure 2), which helps to consider the variation in biophysical and socio-economic conditions observed in the country.

Major drivers of yield (and yield gap) outcomes in Ethiopia

The study showed that income from non-farm sources, value of productive assets, education and shorter plot distance from home reduced the efficiency yield gap. The resource yield gap was attributed to sub-optimal input use, specifically of pesticide and nitrogen. The technology yield gap comprised the largest share of the total yield gap, mostly due to limited use of fertilizer and improved varieties and not using the right type and placement of fertilizers and of improved seeds

The investigation further showed that crop residue and weeding frequency affected maize yield only when nitrogen was applied. In a related study, the authors also showed that maize yield reponse to fertilizer application was dependent on other inputs, specifically type of maize variety, manure application and high rainfall implying the need to integrate agricultural technologies in order to improve and sustain the maize productivity. The authors conclude that targeted but integrated policy design and implementation is required to narrow the overall maize yield gap and improve food security.

“Disaggregating and explaining maize yield gaps is essential to identify potential pathways that can narrow the yield gaps,” said Banchayehu Assefa from CIMMYT.  “This can help guide policy and investments to be more effective at raising smallholder productivity.”

How to improve fertilizer profitability

Modern maize varieties and mineral fertilizers use have been increasing over time and are believed to be among the factors behind the maize yield improvements observed in Ethiopia. However, maize yield response to fertilizer depends on other inputs and management factors and higher fertilizer application rates may not always lead to higher profitability. Using the details of management decisions and biophysical and marketing context, the authors estimated a maize yield response function and evaluated fertilizer yield responses and economic profitability of fertilizer investments by smallholder maize producers. They found that maize yield response to fertilizer was variable with an average value of 7.3 kg maize/ kg N, and it varied from -9 to 18 kg maize /kg. The degree of response was positively affected by phosphorus input and type of maize variety, and negatively by manure input and high rainfall. The key pathways identified to increase the profitability of nitrogen fertilizer use by smallholder maize producers are: improving yield responses with better management (e.g. use of improved maize varieties, complementary use of phosphorus where appropriate); addressing risk aversion (e.g. via crop insurance) in order to strengthen economic incentives for fertilizer investments; enabling the delay of crop sales to take advantage of higher output prices (possibly through expanded access to storage facilities and/or post-harvest loans to alleviate liquidity needs); and improving farm gate price ratios through improved access to markets.

Implications and further research

Even though maize yields have improved recently, under existing management practices smallholders’ maize yield still falls far below the water-limited potential yield. This urges revising the maize sector in terms of input provision, extension services and output markets.  Fertilizer use was highly variable and maize response to fertilizer use depended on other management choices. The study suggests that integrated management practices that work for specific conditions need to be identified, instead of sticking to blanket policy and management recommendations.

This work further points at the importance of additional detailed empirical research on the role of agronomic management practices, to decrease yield gaps. Studying the constraining factors that hinder timely input provision to the farmers might also help to improve input use and hence productivity. In addition, maize prices are too low to advance maize commercialization. Investigating potentials and constraints along the maize value chain might help to improve market participation.
