In the eastern region of Honduras, Mirian Lizeth Torres, an agroindustrial engineer who graduated from the National Autonomous University of Honduras, is making a difference. Her commitment to agricultural sustainability and the empowerment of local communities through sustainable agriculture is evident in her work with the Eastern Regional Farmers Association (ARSAGRO, for its acronym in Spanish) and with her participation in the InnovaHub Oriente, set within the framework of the AgriLAC Resiliente initiative.
“In 2023, I volunteered at ARSAGRO, addressing crucial issues with producers, from events and extension to projects with CIAT that focused on the assessment of plots, water, soil, forest, pests and diseases, bean nutrition, grain quality, among others,” said Mirian, highlighting the breadth of her experience.
Her participation in the InnovaHub Oriente has been key to integrating theory and practice in the field. “I am a student of the conservation agriculture course, where I have explored agronomic practices that improve the sustainability of crops, creating more resilient systems,” she highlights. “These practices are shared with producers through innovation modules, which are plots where conservation agriculture innovations are implemented and compared, side by side, with conventional methods.”
Mirian knows the importance of communicating this knowledge to communities. “At events held on these plots, we shared practices and knowledge, reaching producers who were not familiar with these technologies,” she explains. “Thanks to AgriLAC, in 2023 we contributed significantly to the empowerment of producers and organized groups in eastern Honduras.”
Additionally, Mirian is proud of her role as an inspiration for the inclusion of youth and women in agriculture. “At every event we organize, we see increasing participation of young people and women,” she states. “The empowerment of women in agricultural activities has been notable, with many resuming activities in the field through the transfer of knowledge.”
Looking to the future, Mirian hopes to further encourage youth participation. “My invitation to young people is not to abandon the field; it is that they get involved in agricultural issues to contribute to the livelihood of their families and, at the same time, reduce migration,” she states with determination.
In a world where sustainable agriculture is essential, Mirian Lizeth Torres has assumed solid leadership from the field, helping her community move towards a more sustainable and equitable agricultural future.
Looking to the future, Mirian hopes to further encourage youth participation. “My invitation to young people is not to abandon the field, but rather that they get involved in agricultural issues to contribute to the livelihood of their families and, at the same time, reduce migration,” she states with determination.

Agriculture feeds the world. Yet traditional cycles of ploughing, planting, and harvesting crop and biomass products is inefficient of labor and other scarce resources and depletes soil health while emitting greenhouse gases that contribute to climate change.
One effort to ameliorate the negative effects of farming is a set of practices referred to as conservation agriculture (CA), based on the principles of minimal mechanical soil disturbance, permanent soil cover with plant material, and crop diversification.
To deliver advanced, high-level instruction on current innovative science around important aspects of cropping and farming system management to scientists from India, Bangladesh, Egypt, and Morocco, the 12th Advanced Conservation Agriculture Course hosted by the Indian Council of Agricultural Research (ICAR), CIMMYT, and the Borlaug Institute for South Asia (BISA) took place in India from December 10 to 24, 2023.
SK Chaudhari, deputy director general for Natural Resource Management, ICAR; HS Jat, director of the Indian Council of Agricultural Research-Indian Institute of Maize Research (ICAR-IIMR); Arun Joshi, country representative for India and BISA managing director, CIMMYT-India; Mahesh K. Gathala, senior systems agronomist and science lead, CIMMYT-Bangladesh; and Alison Laing, agroecologist, CIMMYT-Bangladesh, all attended the opening ceremony at the National Agricultural Science Complex in New Delhi, India.
This CA course integrated scientific advancements and multidisciplinary techniques to sustainably develop agricultural systems, restore natural resources, and improve climate resilience in agriculture throughout Asia and North Africa. It was held at leading research centers throughout India.
SK Chaudhari welcomed delegates to the course and stressed its practical character and efficacy in promoting CA management innovations, as evidenced by the significant achievements and international reputations of many former attendees and resource personnel.
“As climatic variability and change increase, the need to manage agronomic risks grows, and CA is an effective tool for farmers and scientists in both irrigated and rainfed systems,” said Chaudhari.
Twenty rising scientists from such fields as agronomy, soil science, plant protection, agricultural engineering, plant breeding, and extension, took part in the workshop where they gained a better understanding of all aspects of conservation agricultural methods in rainfed and irrigated ecosystems, as well as exposure to wide networks with prominent international scientists. Organizers prioritized the inclusion of female scientists, who made up 40% of attendees.
The workshop empowered participants to act as conservation agriculture ambassadors and champions of modern, novel agronomic methods when they return to their home institutions.
Rajbir Singh, ICAR assistant director general for Natural Resource Management, and ML Jat, global research program director of Resilient Farm and Food Systems, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) provided keynote addresses at the closing ceremony, held at the ICAR-Central Soil Salinity Research Institute in Karnal, Haryana, India.

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.
Typically looking like a small caterpillar growing up to 5 cms in length, the fall armyworm (FAW, Spodoptera frugiperda) is usually green or brown in color with an inverted “Y” marking on the head and a series of black dots along the backs. Thriving in warm and humid conditions, it feeds on a wide range of crops including maize, posing a significant challenge to food security, if left unmanaged. The fall armyworm is an invasive crop pest that continues to wreak havoc in most farming communities across Africa.

The first FAW attack in Zimbabwe was recorded around 2016. With a high preference for maize, yield losses for Zimbabwe smallholder farmers are estimated at US$32 million. It has triggered widespread concern among farmers and the global food system as it destroyed large tracts of land with maize crops, which is a key staple and source of farmer livelihood in southern Africa. The speed and extent of the infestation caught farmers and authorities unprepared, leading to significant crop losses and food insecurity.
Exploring the destructive FAW life cycle
It undergoes complete metamorphosis, progressing through four main stages including egg, larva, pupa, and adult. Reproducing rapidly in temperatures ranging from 20 to 38°C, moist soil conditions facilitate the egg-laying process, while mild winters enable its survival in some regions. The larval stage is the most destructive phase, feeding voraciously on plant leaves and can cause severe defoliation. They can migrate in large numbers, devouring entire fields within a short period if left unchecked.
Working towards effective FAW management

Efficient monitoring, early detection, and appropriate management strategies are crucial for mitigating the impact of FAW infestations and protecting agricultural crops. To combat the menace of this destructive pest, CIMMYT, with support from the United States Agency for International Development (USAID), has been implementing research and extension on cultural control practices in Zimbabwe. One such initiative is the “Evaluating Agro-ecological Management Options for Fall Armyworm in Zimbabwe”. Since 2018, this project strives to address research gaps on FAW management and cultural control within sustainable agriculture systems. The focus of the research has been to explore climate-adapted push-pull systems and low-cost control options for smallholder farmers in Zimbabwe who are unable to access and use expensive chemical products.
Environment friendly practices are proving effective to combat FAW risks
To reduce the devastating effects of FAW, the project in Zimbabwe is exploring the integration of legumes into maize-based strip cropping systems as a first line of defense in the Manicaland and Mashonaland east provinces. By planting maize with different, leguminous crops such as cowpea, lablab and mucuna, farmers can disrupt the pests’ feeding patterns and reduce its population. Legumes release volatile compounds that repel FAW, reducing the risk of infestation. Strip cropping also enhances biodiversity, improves soil health and contributes to sustainable agricultural practices. Overall results show that FAW can be effectively managed in such systems and implemented by smallholder farmers. Research results also discovered that natural enemies such as ants are attracted by the legumes further contributing to the biological control of FAW.

Recently, the use of biopesticides such as Fawligen has gained traction as an alternative to fight against fall armyworm. Fawligen is a biocontrol agent that specifically targets the FAW larvae. Its application requires delicate attention – from proper storage to precise mixing and accurate application. Following recommended guidelines is essential to maximize its effectiveness and minimize potential risks to human health and the environment.
Impact in numbers
Since the inception of the project, close to 9,000 farmers participated in trainings and exposure activities and more than 4,007 farmers have adopted the practices on their own field with 1,453 hectares under improved management. Working along with extension officers from the Ministry of Lands, Agriculture, Water, Fisheries & Rural Resettlement, the project has established 15 farmer field schools as hubs of knowledge sharing, promoting several farming interventions including conservation agriculture practices (mulching, minimum tillage through ripping), timely planting, use of improved varieties, maintaining optimum plant population, and use of recommended fertilizers among others.
Addressing FAW requires a multi-faceted approach. The FAW project in Zimbabwe is proactive in tackling infestation by integrating intercropping trials with legumes, harnessing the application of biopesticides, and collaborative research. By adopting sustainable agricultural practices, sharing valuable knowledge, and providing farmers with effective tools and techniques, it is possible to mitigate the impact of FAW and protect agrifood systems.

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.

At CIMMYT’s museum and gene bank, Elouafi met with researchers to discuss the latest discoveries in genetic innovation, biodiversity conservation, and crop breeding. Elouafi and Kevin Pixley, director of the Dryland Crops program, visited the biosafety laboratory and glasshouses where gene editing on pearl millet and ground nut represent cutting-edge work with dryland crops. Elouafi also saw gene editing for resistance to maize lethal necrosis, which is already in field validation with Kenyan partners from the Kenya Agricultural & Livestock Research Organization (KALRO).
Global Wheat and Dryland Crops presented CIMMYT’s 2050 vision for wheat in Africa and near-term goals of advancing partnerships from phenotyping platforms to the International Wheat Improvement Network (IWIN). Seed experts from the Seed Health Unit shared progress on the productivity and nutrition findings of key cereals for healthy and balanced diets.
Elouafi also visited conservation trial plots with Jelle Van Loon, associate director of the Sustainable Agrifood Systems (SAS) program, who briefed Elouafi on cropping systems diversity related to maize, wheat, and beans, and showcased a variety of innovative farming technologies. At the trial plots, Elouafi met with Guillermo Bretón, a farmer, to talk about CIMMYT’s efforts to expand the MasAgro program into Central America aiming to address the region’s growing food insecurity contributing to migration.

The value of genetic resources as sources of novel diversity was discussed with Elouafi during a visit to field screenhouses, where she saw wide crosses work for biological nitrification inhibition (BNI) in wheat, gene bank accessions of triticale—a cross between wheat and rye—for use in searching for new sources of resistance to wheat blast, and the ex-situ clonal collection of tripsacum, a wild relative of maize.
“CIMMYT’s 2030 Strategy adopts a systems approach to food science, which I strongly support. Through the development of mechanization and post-harvest management, increased focus on seed systems and health, and most importantly, cooperation with partners to ensure that improved crop varieties are adopted by smallholders, I am confident that this approach will only strengthen CIMMYT’s historical strength of research and innovation for food and nutrition security and contribute to achieving CGIAR’s 2030 mission,” said Elouafi.
Kevin Kabunda, chief of party for the Southern Africa Accelerated Innovation Delivery Initiative (AID-I) MasAgro Africa Rapid Delivery Hub (AID-I) and Sieglinde Snapp, director of the SAS program, presented key milestones achieved in southern and eastern Africa on expanded seed systems, market access, and mechanization technologies. Snapp also highlighted important CIMMYT-led initiatives like the CGIAR Plant Health Initiative and the Cereal Systems Initiative for South Asia (CSISA) which have had a positive impact on smallholders in part because of partnerships with government agencies and other CGIAR Research Centers.
Elouafi and Govaerts visited the ancient city of Teotihuacán to learn about the cultural significance of maize to the history and agricultural practices of the Americas. She received a guided tour by chef Carlos Cedillo, operational director of La Gruta, a local restaurant dedicated to understanding and promoting the production and consumption of native maize varieties in the Valley of Mexico. CIMMYT has collaborated with La Gruta through capacity building initiatives by CIMMYT specialists for technicians and farmers.

Farmers, stakeholders, and partners, including seed companies, Hamara Chicks, PHI Commodities, the International Livestock Research Institute (ILRI), BioHUB Trust (BHT), Kurima Machinery and Technology, and Zimplow Limited, participated in the Seed and Livestock Fair in the Mbire and Murewa districts of Zimbabwe, which showcased indigenous and improved seed varieties and different technologies to strengthen crop and livestock value chain systems.
Initiated by CIMMYT in 2022, as the CGIAR Initiative on Agroecology, these series of fairs have become instrumental in bringing agrodealers closer to farmers and showcasing sustainable technologies and innovations that have the potential to strengthen production systems. It was also an opportunity for the agroecology initiative team to provide feedback to farmers and stakeholders on ongoing activities and technologies that were being tested since the initiative’s inception in Zimbabwe. By adopting a multi-partner approach, these fairs bring local food systems actors together to ensure food and nutrition security and improved income for farmers.
“The agroecology initiative has been collaborating with an array of organizations and institutes that can support our mission towards promoting agroecology and improving farming production, including other CGAIR entities like IWMI and ILRI, Hamara Group, Ecolyfe, and PHI Commodities,” said Dorcas Matangi, research associate at CIMMYT.
This year’s edition of the seed and livestock fair “Fostering Synergies: Diverse Crops, Livestock and Inclusive Communities” advocated for enhancing synergies within the farm to foster sustainable agroecology transitions for resilient food and nutrition outcomes. With over 800 farmers and stakeholders participating, the event provided a vibrant platform for knowledge sharing, exploration of indigenous and improved seed varieties, and sensitization of innovative technologies.
“The seed and livestock fairs hosted by the agroecology initiative bring together farmers and food system actors from all walks of life to foster learning around agroecology, which includes the importance of diversity (crop and livestock) while also appreciating local innovations in the respective area,” said Jesca Mapfinya, a Murewa farmer.
The right seed, assures a good harvest
Various seed companies participated in the fair to showcase different seeds which are well adapted in Murewa and Mbire districts. Each agroecological region in Zimbabwe is unique, with adaptable seed varieties that are either landrace or improved. Local landraces and many underutilized crop species are adapted to weather and climate variability, climate change, and extreme weather such as drought and heat stress. Farmers indicated that their motivations for growing landraces are related to sustainable farming systems suitable for social, cultural, nutritional, and agronomic traits. Their place in rural communities remains important, providing much-needed functional diversity and social capital. Including improved varieties within the basket of options can further intensify production systems in these communities.
“Primarily, we sell seed varieties and build farmer capacity around appropriate agronomic practices. The seed fairs are a good platform to match seeds and systems and allows a farmer to provide feedback about our seed varieties and how they are performing in the respective areas,” said Onesmous Satenga, SeedCo.

Building crop and livestock synergies
For the first time since the inception of the fairs, livestock such as cattle, sheep, goats, chicken and rabbits were displayed. Partners, including ILRI and the Hamara Chicks, who are into sasso chicken and feed production, reiterated the importance of crop diversity for improved livestock nutrition. ILRI and the Grasslands Research Institute exhibited various local feedstocks and alternative livestock feed grasses and also presented several feed formulations. Farmers also provided feedback on the feeding strategies employed for different livestock.
“We feed cattle with poultry litter, maize grain, maize stover, and groundnut shells in various proportions depending on the availability of these feed sources. Forage legumes such as velvet bean (mucuna pruriens) and lablab (lablab purpureus) have been introduced, and we have started to grow these for feed,” said Samson Tashaya, Murewa farmer.

Of keen interest to farmers and stakeholders was the sasso breed of chickens that the Hamara Group was promoting.
“We have recently joined as partners with CIMMYT and are promoting hybrid chicken production, especially sasso, here in Murewa ward 27 and 4. This is our first time coming to this seed fair, and it was a learning opportunity. The interactions with farmers were really good,” said Alan Norton, team leader at Hamara Chicks.
Modernizing smallholder production systems
Mechanization experts from Kurima Machinery and Zimplow shared their recommendations at the fair. They acknowledged that farmers rely heavily on scarcely available labor and production activities that are backbreaking. They advocated for modern production systems to produce more food and support economic transformation. Experts from Kurima Machinery and Zimplow demonstrated several machines that could aid farmers in various on-farm activities.
“This fair has come at the right time as I begin land preparation for my pfumvudza (conservation agriculture plots). I have seen how the basin digger works, and I am keen to purchase an instrument to make my work much easier,” said Chief Chisunga, Mbire.
“This crop season’s outlook is still unclear, but weather experts have warned of an intense El Nino event likely to happen in the second half of the season. Technologies such as conservation agriculture can ensure good moisture retention in crop fields, and it needs to be paired with good agronomic practices,” said Tafadzwanashe Mabhaudhi, climate and food systems expert.

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.
Small-scale farmers in Mexico often adopt conservation agriculture innovations gradually and piecemeal, to fit their diverse agroecological and socioeconomic contexts and risk appetites, according to studies and the on-farm experience of CIMMYT.
Research and extension efforts need to consider this in work with smallholders, said Santiago Lopez-Ridaura, a CIMMYT specialist in agricultural systems and climate change adaptation.
“Farmer practices typically involve heavy tillage before seeding, growing maize as a monocrop, and removing crop residues after harvest for use as forage,” explained Lopez-Ridaura. “Full-on conservation agriculture (CA) is a radical shift, requiring farmers to reduce or eliminate tillage, keep a permanent cover of crop residues on the soil, and diversify the crops they grow. It can support more intense yet environmentally friendly farming, reducing erosion, improving soil fertility and water filtration, boosting crop yields, and saving farmers money. However, it also requires purchasing or contracting specialized sowing implements and fencing fields or agreeing with neighbors to keep livestock from eating all the residues, to name just a few changes.”

Lopez-Ridaura and colleagues published a 2021 analysis involving farmers who grew maize and sorghum and keep a few livestock on small landholdings (less than 4 hectares), with limited mechanization and irrigation, in the state of Guanajuato, Central Mexico.
They found that scenarios involving hybrid maize plus a legume crop with zero-tillage or keeping a residue mulch on the soil provided an average net profit of some US $1,600 (MXP 29,000) per year, in addition to ecological benefits, added forage, and more stable output under climate stress.
“Using a modeling framework from Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO) that combines bioeconomic simulation, risk analysis, adoption theory, and impact assessment, we not only confirmed the worth of conservation agriculture but found that disaggregating CA into smaller component packages and including a more productive crop and variety were likely to increase farmers’ adoption, in riskier settings.”
Advancing more sustainable farming in Mexico
Conservation agriculture can generate substantial economic and environmental benefits under marginal conditions, particularly by enhancing climate change resilience, increasing soil organic matter, and retaining soil moisture. In Central Mexico dryland maize yields rose by 38-48%, after 10 years of implementing CA.

CIMMYT has studied and promoted zero-tillage for maize and other resource-conserving practices in Mexico for more than three decades, but efforts to spread sustainable farming and use of improved maize and wheat varieties redoubled thanks to MasAgro, a research initiative led by the Center and supported by the government of Mexico during 2010-21. Testimonials such abound of Mexican smallholder farmers who have adopted and benefited from CA practices through CIMMYT and national partners’ efforts in MasAgro and other initiatives.
Looking to lower his farm costs without losing output, wheat and oil crop farmer Alfonso Romo of Valle de Mayo, state of Sonora, began practicing CA in 2010. “We’ve learned a lot and this year (2022) we obtained the same yields as we used to get through conventional practices but, following more sustainable farming methods, with a 30 and even 40% savings in fertilizer.”
With CA practices he adopted in 2018 through MasAgro, maize farmer Rafael Jacobo of Salvatierra, state of Guanajuato, obtained a good crop despite the late dispersal of irrigation water. Seeing his success and that of other nearby farmers, neighbor Jorge Luis Rosillo began using CA techniques and has noticed yearly improvements in his soil and yields. “I did everything the technicians recommended: keeping the residues on the soil and renewing only the sowing line on soil beds…. There are lots of advantages but above all the (cost) savings in land preparation.”

Farmers in the Milpa Sustentable project in the Yucatán Peninsula have improved maize yields using locally adapted CA methods, in collaboration with the Autonomous University of Yucatán. Former project participant Viridiana Sei said she particularly liked the respectful knowledge sharing between farmers and project technicians.
CA practices have allowed more than 320 women farmers in the Mixteca Region of the state of Oaxaca to provide more and better forage for the farm animals they depend on, despite drought conditions, through the Crop and Livestock Conservation Agriculture (CLCA) project supported by the International Fund for Agricultural Development (IFAD). According to farmer María Martínez Cruz, “… it hasn’t rained much and everything’s dry, but our verdant oat crop is allowing us to keep our farm animals fed.”
With CLCA support and facing Mexico’s increasingly fickle rainy season, farmer Mario Guzmán Manuel of San Francisco Chindúa village in Oaxaca began using CA and says he’ll never go back to the old practices. “We used to do as many as two harrow plowings to break up the soil, but if we leave the residues from the previous crop, they hold in the soil moisture more effectively. People hang onto the old ways, preferring to burn crop residues, but we should understand that this practice only deprives the soil of its capacity to produce.”
Supporting farmers and local communities can better and more quickly preserve the Yucatán peninsula’s biodiversity in the mid and long term, as well as the agricultural heritage of its Indigenous peoples.

Smallholder farmers in resource-poor communities of Zimbabwe and much of the Global South have been experiencing low crop productivity due to many factors, including inappropriate seeds and seed varieties, labor shortages, loss of agro-biodiversity, insufficient inputs, degrading soils, and recurrent droughts. These threats are now amplified by climate change.
This has resulted in broken food systems rendering food and nutrition insecurity commonplace. The One CGIAR initiative, Transformational Agroecology Across Food, Land, and Water Systems, led by the International Maize and Wheat Improvement Center (CIMMYT) in Zimbabwe, is designed to bring agroecological advances to smallholder famers in an effort to strengthen local food systems.
Smallholder farmers in the Mbire and Murehwa Districts of Zimbabwe were introduced to innovative agroecology interventions, premised on harnessing nature’s goods and services while minimizing adverse environmental impacts and improving farmer-consumer connectivity, knowledge co-creation, and inclusive relationships among food system actors.

Farmer to farmer collaboration at seed fairs
In response to challenges related to lack of appropriate seeds and eroding agrobiodiversity and, as a way to transition prevailing food systems to more sustainable ones, farmers were invited to take part in seed fairs. The seed fair’s objective was to enable smallholder farmers to access improved and locally adapted seeds of food crops originating from the private sector and fellow farmers. In addition, the seed fairs provided a platform for learning about agroecological practices. Farmers were also given a chance to see different machinery that could aid in land, food, and feed preparation, and address their labor shortage challenges.
At the opening of the seed fair in Mbire, Dorcas Matangi, CIMMYT research associate, acknowledged that smallholder farmers operate in challenging and complex ecological, social, and economic systems and there is a need for interventions that address the natural resource base without ignoring the social and economic dynamics within communities.
“The communal culture of sharing and trading between community members can be capitalized on for a collective benefit, said Matangi. “One such case is through events such as seed fairs where we encourage farmers to showcase and sell seeds they know perform very well.”
She further explained to the participating farmers how increasing their crop diversity and using practices such as conservation agriculture techniques benefit the environment and improves food security and nutrition.
“I am grateful for these efforts,” said Grace Musandaira, supervisor of the Agriculture Advisory and Rural Development Service. “Our region is arid, and as such, it is very difficult for our farmers to achieve significant yields to assure them there is enough food for the year. In addition, the knowledge provision relating to preserving and improving agrobiodiversity through agroecological practices is set to improve rural livelihoods.”
Senzeni Nyagonye, a farmer in Mbire, said “This initiative is teaching and exposing us to so many new concepts such as conservation agriculture with mechanization. If we can apply conservation agriculture with the seeds we bought at this seed fair, we are optimistic about a great harvest.”
A total of 1,058 farmers attended two seed fairs in Mbire and Murehwa. Farmers had the opportunity to access a variety of crop seeds ranging from maize, to sorghum, millets, groundnuts, bambara groundnuts, and sunflowers. More than 200 farmers exhibited local seeds that were available for sale or exchange. Private seed companies also showcased and sold certified drought-tolerant maize, sorghum, bean and cowpea varieties.
“The seed fairs in Mbire and Murehwa were very successful”, said Matangi. “And we feel these efforts will serve as a useful case study to guide a national scale-up.”
Higher levels of potential carbon mineralization (Cmin) in soil indicate that the soil is healthier. Many reports indicate that Cmin in agricultural soils increases with reductions in soil disturbance through tillage, but the mechanisms driving these increases are not well understood.
The International Maize and Wheat Improvement Center (CIMMYT) has established a network of research platforms in Mexico, where collaborating scientists evaluate conservation agriculture and other sustainable technologies to generate data on how to improve local production systems. This network of research trials, many of which have over five years in operation, allowed us to participate with Mexican sites in the North American Project to Evaluate Soil Health Measurements (NAPESHM). This project aimed to identify widely applicable soil health indicators and evaluate the effects of sustainable practices on soil health in 124 long-term experiments across Canada, the United States of America, and Mexico.
Experienced field teams from CIMMYT sampled the soils from 16 experiments in Mexico, which were then analyzed by the Soil Health Institute for this study. Potential carbon mineralization, 16S rRNA sequences, and soil characterization data were collected, with results demonstrating that microbial (archaeal and bacterial) sensitivity to physical disturbance is influenced by cropping system, the intensity of the disturbance, and soil pH.
A subset of 28 percent of amplicon sequence variants were enriched in soils managed with minimal disturbance. These enriched sequences, which were important in modeling Cmin, were connected to organisms that produce extracellular polymeric substances and contain metabolic strategies suited for tolerating environmental stressors.
The unique sampling design of this study – analyzing across a variety of agricultural soils and climate – allows to evaluate management impacts on standardized measures of soil microbial activity. Additionally, understanding the microbial drivers of soil health indicators like Cmin can help with the interpretation of those indicators and ultimately the understanding of how to better manage soils.
