The World Food Prize honored Cary Fowler and Geoffrey Hawtin for their lifelong dedication to preserving genetic resources critical to global food security. They have led efforts to protect seeds from over 6,000 crops by establishing germplasm banks worldwide, including the Svalbard Global Seed Vault, to safeguard biodiversity against climate threats. With partners like INIFAP, CIMMYT has played a key role in conserving the genetic diversity of staple crops, ensuring these resources are available for future agricultural resilience.
At the UN General Assembly, the U.S. Department of State announced $5 million in food security assistance to advance the Vision for Adapted Crops and Soils initiative in Guatemala. Co-led by CIMMYT and FAO, it aims to enhance sustainable agriculture through innovative practices that improve soil health and crop diversity. This initiative, part of the U.S. Feed the Future program, will strengthen resilience to climate change and support Guatemala’s agricultural sector, directly benefiting the 1.6 million people dependent on farming. CIMMYT’s leadership ensures scientific expertise in crop and soil management is central to addressing food insecurity and malnutrition in the region.
Melinda Smale’s groundbreaking work in agricultural economics, particularly her collaboration with CIMMYT, has played a pivotal role in advancing the understanding of crop diversity conservation. At CIMMYT, Smale worked with plant breeders and agronomists to analyze maize landraces and wheat genetic diversity, contributing to the development of strategies that support sustainable agriculture and food security. Her research has informed CIMMYT’s efforts to preserve biodiversity and enhance the resilience of farming systems, directly aligning with the organization’s mission to improve global food security through science and innovation.
Science without policy is just academia; policy without science is just guesswork. Through a blend of robust field research and policy advocacy, CIMMYT aims to bridge the gap between policy and practice in promoting sustainable agricultural practices through crop diversification in South Asia.
Taking Bangladesh as an example, CIMMYT’s work in the country highlights the critical need to link research with policy to achieve sustainable agricultural practices, enhance food security, and improve farmer livelihoods.
The power of research-informed policy
Bangladesh’s agriculture is highly rice-centric; although rational, this is risky and arguably unsustainable. This means there needs to be a focus on crop diversification, which is one of the approaches toward sustainable agriculture that can address socioeconomic and environmental challenges.
Recognizing these challenges, CIMMYT has been at the forefront of developing solutions by conducting extensive multi-location on-site and on-farm trials that consider the socioeconomic and pedoclimatic dimensions of farm households.
Additionally, CIMMYT analyzes historical policies and initiatives that have been implemented by the Bangladeshi government and international partners to promote crop diversification. Several opportunities for improvement were identified in past policies and project implementation; addressing these challenges requires bridging the gap between policies and research to scale up crop diversification efforts.
Through the RUPANTAR and CGIAR Transforming Agrifood Systems in South Asia (TAFSSA) projects, CIMMYT-Bangladesh has developed an analytical tool to understand the political economy of crop diversification policies and practices. When applied to agriculture policy research, this tool can be tailored to any country and policy context in South Asia.
For example, while the government recognizes crop diversification in its agriculture policies starting with the Fifth Five-Year Plan, substantial funding for crop diversification efforts was only recently allocated. Integration of crop diversification into the government’s annual funding systems is essential to mainstream crop diversification in agriculture.
Many crop diversification policies and projects primarily focus on production, neglecting market systems development for new crops. Similarly, research suggests insufficient attention is paid to cold storage and other infrastructure needed to support diversification.
Most initiatives appear to have been project-driven, resulting in short-lived action without long-lasting impact. Insufficient coordination and support from government agencies appears to have affected projects led by both governments and development partners.
Stakeholder engagement spreads awareness
Without translating research into policy, we leave innovation on the shelf. CIMMYT-Bangladesh disseminates research findings to policymakers through the country Priority Investment Plan for the crop sector at the Bangladesh Agricultural Research Council (BARC), and South Asian Association for Regional Cooperation (SAARC) member countries through regional consultation workshops on accelerating the transformation process for sustainable and nutrition-sensitive food systems.
Looking ahead, CIMMYT’s efforts in South Asia remain dedicated to bridging the gap between research and policy. Ongoing projects aim to generate robust evidence, advocate for informed policy decisions, and foster partnerships across sectors. By continuing to lead in this space, CIMMYT strives to contribute to a more resilient agrifood system for South Asia.
Bangladesh’s agricultural landscape is evolving rapidly, with initiatives focused on modernization, sustainability, and innovation. Projects supported by the United States Agency for International Development (USAID) are working to advance the country’s agriculture through stakeholder collaboration, enhancing productivity, improving mechanization, and embedding sustainable practices.
To explore the impact of this work, USAID officials and senior staff from CIMMYT embarked on a comprehensive tour across multiple project sites on 14 – 19 April 2024. The USAID delegation featured Zachary P. Stewart, production systems specialist from the Bureau for Resilience, Environment, and Food Security, and John Laborde and Muhammad Nuruzzaman from the USAID Bangladesh Mission. From CIMMYT, the team included Sieglinde Snapp, program director from the Sustainable Agrifood Systems Program, Timothy J. Krupnik, country representative for Bangladesh, and Owen Calvert, project leader for the Cereal Systems Initiative for South Asia-Mechanization Extension Activity (CSISA-MEA).

Pioneering agricultural technology
The team visited Dinajpur, Bangladesh to observe the progress of the Transforming Agrifood Systems in South Asia (TAFSSA) CGIAR Initiative, including creative efforts to raise agricultural output, support sustainable practices, and boost the area’s nutrition levels. The integrated strategy of TAFSSA, which combines inclusive community participation with socio-agronomic research, has enabled local farmers to increase revenue, diversify their crop production, and enhance yields. From the premium quality rice (PQR) value chain at the Bengal Auto Rice Mill to the sustainable intensification of mixed farming systems, the visit demonstrated TAFSSA’s dedication to building agricultural resilience and improving lives throughout Bangladesh.
In Faridpur, the team observed CSISA-MEA, a five-year project dedicated to supporting smart mechanization in Bangladesh. This included displays of innovative agricultural machinery, such as onion storage blowers, jute fiber separators, axial flow pumps, and combine harvester spare parts. Stakeholders from various sectors shared insights on how to improve machine service providers’ capacity to manage their businesses effectively.
Sholakundu, a village in Kanaipur Union, Faridpur Sadar, has embraced modern agricultural practices and diversified crop cultivation. This site showcased the impact of mechanized rice transplantation and integrated pest management (IPM) techniques, with the opportunity to observe a live demonstration of mat-type seedling raising for mechanized rice transplantation. Discussions revolved around the benefits of mechanization, IPM activities, and the village’s commitment to enhancing agricultural sustainability and productivity.
Climate-specific farming
The southern coastal region of Bangladesh has long suffered from problems including salinity, drought, waterlogging, and unpredictable weather. Addressing these issues is the USAID-funded Sustainable Intensification Innovation Lab–Asian Mega Delta (SIIL-AMD) project, which encourages climate-resilient farming and better water management.
The initiative engages approximately 400 farmers in trials of improved agronomic techniques through the use of 14 Learning Hubs and the Cluster Farmer Field School (CFFS), aiming to increase output and assist local people in adjusting to the special conditions of the coastal polder zone.
“Bangladesh’s women farmers, especially those in this area and the coastal regions, are incredibly hardworking,” stated Zachary P. Stewart. “Even in the face of adverse weather conditions, their dedication has led to excellent crop yields. If provided with further training and allocated more time, these industrious women could take the lead in driving Bangladesh’s agricultural progress forward.”

Systemic self-sufficiency
For reasons of development and sustainability, Bangladesh’s agriculture industry is focused on using locally made machinery and spare parts. As USAID personnel visited the SMR Agro Engineering Workshop and Foundry, situated in Jashore Sadar, they witnessed how support by CSISA-MEA has improved the agricultural mechanization market system. SMR Agro Engineering produces high-quality agricultural machinery and spare parts, increasing farmers’ productivity and decreasing labor intensity.
CSISA-MEA’s support has been significant in preparing new industrial layouts, raising labor skill levels, providing technical guidance, and facilitating financing. Moreover, through the development of business partnerships with lead companies, agriculture-based light engineering enterprises (ABLEs), and dealers, CSISA-MEA ensures a strong network that supports the widespread use of mechanized services. This collaborative effort marks a significant step towards enhancing rural livelihoods and achieving sustainable agricultural practices in Bangladesh.
Global research partnerships
In addition to visiting farmers’ fields, the team also attended the Bangladesh Agricultural Research Institute (BARI), the nation’s largest agricultural research center which focuses on improving crop yields, food security, and employment. The visitors explored the work in mechanization, IPM, and farm machinery, with a tour of BARI’s IPM and toxicology laboratories highlighting the organizations’ sustainable approach to pest management.
The final visit was to Ispahani Agro Limited (IAL), a leading bio-pesticide producer in Gazipur. IAL is at the forefront of bio-rational pest management, creating environmentally friendly, non-toxic inputs. CIMMYT’s assistance has been crucial for the company’s growth, with the tour covering production units, laboratories, and discussions on IAL’s business development.
Overall, the experience offered a comprehensive overview of collaborative activities between USAID, CIMMYT, and Bangladeshi stakeholders. From research and mechanization to bio-rational pest management, the combined efforts boost output and encourage sustainability and responsible environmental behavior.
As Bangladesh continues to embrace modern farming practices, partnerships and projects will play a pivotal role in defining how the country’s agricultural industry evolves into one that is economically viable and sustainable.
I am Grace Malaicha, a proud native of the Zidyana Extension Planning Areas in Central Malawi, where my journey with Conservation Agriculture (CA) began. In 2005, I observed neighboring farmers practicing CA techniques on their land. Intrigued and inspired, I decided to embark on this path myself, joining the CA program initiated by CIMMYT and Total LandCare in 2006. I started practicing it on my demonstration plot and observed that yields were getting higher from the second year onwards.
My dedication to CA has changed not only myself but also influenced other members of my farming community. As a mother trial host farmer under the CGIAR Initiative: Diversification for resilient agribusiness ecosystems in East and Southern Africa today, I have been implementing different treatments, which include maize doubled-up legume system and improved drought-tolerant maize varieties planted under CA on flat land and comparing it to the traditional ridge tillage system that involves substantial soil movement.
But what does CA mean to me? It is more than just a set of principles that I apply like minimum soil disturbance, mulching, and crop rotation. CA reduces drudgery, secures yields, and maintains productivity in times of climate change. CA has changed my approach to farming, transforming my once conventional maize monocrop into a diverse maize-legume system. By intercropping with two crops, I have spread the risk of unanticipated crop failure, while incorporating groundnut, cowpeas, and pigeon pea into the mix, which are more drought tolerant. I increased the land area under CA and tried it on many other crops including different legumes as rotation or intercrops, birds-eye chili, vegetables, and cassava.
Over the years, I have witnessed firsthand the harsh realities of a changing climate in central Malawi, from intense heat to prolonged droughts and erratic rainfall patterns. This year, 2024, has even been worse due to the prolonged dry spells between January and February, and the erratic rainfall during this time. Despite these challenges, our CA plots have continued to thrive, showcasing the resilience and adaptability of climate-smart farming practices.

Recognizing the power of knowledge sharing and from the encouragement by CIMMYT and Total LandCare, I started to train fellow farmers, both locally and across borders. At first, I worked with women groups around my homestead and trained about 100 female farmers on the principles of CA. I was fortunate to be given the opportunity to train other farmers in other districts of Malawi. Since 2008, I have also trained farmers in eastern Zambia and from Mozambique where all farmers speak my language Chichewa. Farmers believe other farmers more and are now realizing the benefits of implementing CA in their own fields.
I enrolled to be a local trainer in CA within my community in 2016. My passion for teaching and catalyzing change has led to the adoption of CA by numerous farmers. I embrace my commitment to ongoing learning through carefully implementing these CA trials and playing an active role during awareness meetings.
My life had changed so much. I was speaking on the radio and television. In 2012, the Minister of Agriculture visited my plot, and I was asked to speak in front of a Parliamentary Committee about my experiences as a smallholder woman farmer in Malawi. I spoke about what women can do in agriculture and what changes I made on my land. From representing my country at high level meetings, each step has shaped me into a resilient and empowered woman.
However, my journey has not been without obstacles, including hardships in my personal relationship. In 2012, I made the decision to join my husband in South Africa where I took up menial jobs to earn a living, abandoning my plot back home. But my true passion lay in farming, and I decided to make the bold decision to come back home, leaving my husband and continue with farming. Through perseverance and determination, I have overcome these challenges, and I am now much stronger.

Today, I stand with pride in front of my CA plot, not only sustaining my family but also sending all my children to school. I now converted all my land to conservation agriculture, 3ha are under maize and 2ha under groundnuts. Beyond farming, I have investments in housing, claiming rentals in the nearby town of Salima to sustain my financial income and expand in farming.
I will continue on this path as I learned so much over the years and believe that CA may be the only climate-smart agriculture response in reach of smallholder farmers that everybody can apply, and I will continue to support others as a champion of CA.
Over the last seventy years, intensively managed monocultures, focused on maximizing calorie production, have become a dominant approach to global food production. This trend toward simplification in agricultural systems has supported productivity gains but has very troubling consequences for the environment including nutrient pollution and biodiversity loss at a massive scale. Restoring diversity is essential to regaining ecological balance.
Monocultures are generally all the same, turning biologically-rich systems into chemical-intensive engineered ones nearly devoid of life forms other than those yielding a genetically identical commodity crop. Their guiding principle is producing food ingredients as cheaply as possible. Biologically diversified agricultural systems can take many forms. Their guiding principle is recapturing resilience and resource use efficiency while supplying balanced diets and viable livelihoods.
In recent years, there have been many efforts to biologically diversify farming systems. Increasing the number of species and the genetic diversity is associated with improved resilience and resource use efficiency.
A new paper published in Science consolidates evidence from across a wide range of diversification strategies, applied on five continents, to understand how they affect environmental and social outcomes. These strategies encompass many different interventions ranging from crop rotations and cover crops to livestock inclusion to use of compost, hedgerows, and contour farming.

The study shows that the likelihood of environmental and social benefits goes up when a greater number of diversification strategies are combined. Importantly, the environmental benefits of diversification were found to be greatest in very simplified landscapes with less than 20% in non-crop area.
It also found that applying multiple diversification strategies in tandem reduces tradeoffs. In other words, the path to agricultural win-wins leads to diversified working landscapes, not just diversification strategies on individual farms.
The push toward commodity monocultures has been baked into many agricultural policies, such as subsidies and trade deals, and into land tenure systems. The monoculture bias is also reinforced through pricing, payment, and other supply chain arrangements. Even research agendas have encouraged monoculture with the long-term emphasis on yield-focused breeding.
It’s time to dismantle the structural barriers that leave so many farmers just getting by “against the odds” and at the expense of functioning ecosystems.

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.
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.

Rapid urbanization, globalization, economic development, technological advancement, and changing agriculture production systems in South Asia are transforming food systems and the food environment.
India and Bangladesh, particularly, have seen a significant transformation since the advent of the Green Revolution as each became able to feed their population without having to import major crops.
However, that policy focus on food self-sufficiency and yield intensification has incurred significant health, environmental and fiscal costs, including a precipitous drop in crop diversification*.
This loss of crop diversification threatens economic and social development and environmental stability while weakening the crucial link between agriculture and community health, particularly in undernourished rural areas. To ensure sustainable food production and nutritional security, it is imperative to manage and conserve crop diversification.
To address these issues and ensure sustainable food production, there is an urgent need to transition from intensive to sustainable farming practices.
CIMMYT exploring crop diversification pathways
CIMMYT’s ongoing projects in South Asia, including the Transforming Agrifood Systems in South Asia (TAFSSA) and Transforming Smallholder Food Systems in the Eastern Gangetic Plains (RUPANTAR) are conducting extensive on-site and on-farm trials, including socioeconomic dimensions of farmers to promote crop diversification.
“To effectively address the challenges of crop diversification, it is essential to integrate on-farm trials and participatory action research, involving farmers in the experimentation and adaptation process tailored to their unique regional needs,” said Ravi Nandi, innovation systems scientist at CIMMYT in Bangladesh. “This hands-on involvement provides valuable data to guide policymaking, ensuring relevance and applicability.”
In addition, TAFSSA and RUPANTAR are engaging in participatory action research to uncover the most viable options for crop and livelihood diversification, understand the socioeconomic factors impacting farmers, and identify the potential opportunities and challenges associated with the crop and livelihood diversification efforts among the farmers.
Researchers completed two comprehensive surveys, engaging with 2,500 farmers across the Eastern Gangetic Plains (EGP) of India, Nepal and Bangladesh, yielding valuable data that will inform future strategies for crop diversification in the region.
Ongoing investigations into the political economy of policies for crop diversification in Bangladesh generate novel insights, further contributing to the development of efficient crop diversification projects and sustainable agricultural policies.
The rise of crop diversification in practices and policy
In recent years, crop diversification has gained traction as a promising strategy to boost agricultural productivity, reduce risks (production, market, climate, and environmental), enhance nutritional outcomes, and promote sustainable agriculture.
Following the inaugural National Conference of Chief Secretaries in Dharamshala, India, led by the Prime Minister of India, state governments introduced numerous policies and schemes to support crop diversification. Some of these initiatives, highlighted in Figure 1, were backed by substantial budget allocations aimed at motivating farmers to diversify their crop production from the current intensive production system.
Figure 1: Author’s compilation from various public sources.
Similar initiatives have been started in Bangladesh, Nepal and other South Asian countries to promote crop diversification. These policies and schemes are important steps towards addressing inadequacies that intensive farming has created in agriculture and food systems.
While policies promoting crop diversification in South Asia are a positive step, their effectiveness is contingent on evidence-based decision-making. The complexities of implementing diversification strategies vary significantly depending on local contexts, particularly in countries like India, Nepal and Bangladesh, where most farmers operate on less than one hectare of land and face diverse weather conditions.
Smallholder farmers, at risk of losing economic stability from abandoning profitable monocrops, face additional challenges because of limited access to advanced technologies and fragmented markets, making the transition to diversified farming a precarious endeavor.
A shift towards comprehensive multi-criteria assessments, including qualitative methods and stakeholder interactions, is necessary for creating practical and locally relevant indicators. Supporting infrastructure, accessible extension services and market development, along with empowering farmers through education on agronomic practices and crop management, will play a crucial role in successfully implementing and reaping the benefits of crop diversification.
*Crop diversification is a process that makes a simplified cropping systems more diverse in time and space by adding additional crops.
The Eastern Gangetic Plains (EGP) are vulnerable to climate change and face tremendous challenges, including heat, drought, and floods. More than 400 million people in this region depend on agriculture for their livelihoods and food security; improvements to their farming systems on a wide scale can contribute to the Sustainable Development Goals (SDGs).
The Australian Centre for International Agricultural Research (ACIAR) has been supporting smallholder farmers to make agriculture more profitable, productive, and sustainable while also safeguarding the environment and encouraging women’s participation through a partnership with the International Maize and Wheat Improvement Center (CIMMYT). On World Food Day, these projects are more important than ever, as scientists strive to leave no one behind.
The EGP have the potential to significantly improve food security in South Asia, but agricultural production is still poor, and diversification opportunities are few. This is a result of underdeveloped markets, a lack of agricultural knowledge and service networks, insufficient development of available water resources, and low adoption of sustainable farming techniques.
Current food systems in the EGP fail to provide smallholder farmers with a viable means to prosper, do not provide recommended diets, and impose undue strain on the region’s natural resources. It is therefore crucial to transform the food system with practical technological solutions for smallholders and with scaling-up initiatives.

ACIAR: Understanding and promoting sustainable transformation of food systems
Over the past ten years, ACIAR has extensively focused research on various agricultural techniques in this region. The Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project sought to understand local systems, demonstrate the efficacy of Conservation Agriculture-based Sustainable Intensification (CASI) approaches, and create an environment that would support and scale-up these technologies.
To establish a connection between research outputs and development goals, the Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar) project expands on previous work and partnership networks. This is a collaborative venture with CIMMYT that demonstrates inclusive diversification pathways, defines scaling up procedures for millions of smallholder farmers in the region, and produces a better understanding of the policies that support diversification.
Building the future and inspiring communities
Men and women both contribute substantially to farming activities in the EGP of India, Bangladesh, and Nepal, but gender roles differ according to location, crops and opportunities. It is a prevalent perception supported by culture, tradition, and social biases that women cannot be head of the household.
In Coochbehar, India, the unfortunate passing of Jahanara Bibi’s husband left her as head of her household and sole guardian of her only son. Though a tragic event, Bibi never gave up hope.
Going through hardships of a rural single female farmer intensified by poverty, Bibi came to know about CASI techniques and the use of zero-till machines.
Though it seemed like a far-fetched technique at first and with no large network to rely on for advice, Bibi decided to gather all her courage and give it a try. Being lower cost, more productive, adding income, and saving her time and energy all encouraged Bibi to adopt this zero-till machine in 2013, which she uses to this day. Today, she advocates for CASI technology-based farming and has stood tall as an inspiration to men and women.
“I feel happy when people come to me for advice – the same people who once thought I was good for nothing,” said Bibi.
With no regrets from life and grateful for all the support she received, Bibi dreams of her future as a female agro-entrepreneur. Being a lead female farmer of her community and having good contact with the agriculture office and conducive connection with local service providers, she believes that her dream is completely achievable and can inspire many single rural female farmers like herself to encourage them to change perceptions about the role of women.

ML Jat, a principal scientist at CIMMYT, speaks with The Times of India about the work of CIMMYT and its partners on diversification and carbon credits—two futuristic ways to reduce greenhouse gas emissions from agriculture in India.
The Indian Council of Agricultural Research (ICAR), together with CIMMYT and partners, organized a State Level Maize Day in the state of Haryana to discuss sustainable maize production systems for future generations.

New research by an international team of scientists, including scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research (ICAR), shows that adopting a portfolio of conservation agriculture and crop diversification practices is more profitable and better for the environment than conventional agriculture.
Reported last month in Nature Scientific Reports, the results of the study should encourage farmers and policymakers in South Asia to adopt more sustainable crop management solutions such as diversifying crop rotations, direct-seeding rice, zero tillage and crop residue retention.
Rice-wheat has for a long time been the dominant cropping system in the western Indo-Gangetic plains in India. However, issues such as water depletion, soil degradation and environmental quality as well as profitability have plagued farmers, scientists and decision makers for decades. To tackle these issues, researchers and policymakers have been exploring alternative solutions such as diversifying rice with alternative crops like maize.
“Climate change and natural resource degradation are serious threats to smallholder farmers in South Asia that require evidence-based sustainable solutions. ICAR have been working closely with CIMMYT and partners to tackle these threats,” said SK Chaudhari, deputy director general of the Natural Resource Management at ICAR.
In the study, CIMMYT scientists partnered with the ICAR-Central Soil Salinity Research Institute, International Rice Research Institute (IRRI), Borlaug Institute for South Asia (BISA), Swami Keshwan Rajasthan Agriculture University and Cornell University to evaluate seven cropping system management scenarios.
The researchers measured a business-as-usual approach, and six alternative conservation agriculture and crop diversification approaches, across a variety of indicators including profitability, water use and global warming potential.

They found that conservation agriculture-based approaches outperformed conventional farming approaches on a variety of indicators. For example, conservation agriculture-based rice management was found to increase profitability by 12%, while decreasing water use by 19% and global warming potential by 28%. Substituting rice with conservation agriculture-based maize led to improvements in profitability of 16% and dramatic reductions in water use and global warming potential of 84% and 95%. Adding the fast-growing legume mung bean to maize-wheat rotations also increased productivity by 11%, profitability by 25%, and significantly decreased water use by 64% and global warming potential by 106%.
However, CIMMYT Principal Scientist and study co-author M.L. Jat cautioned against the allure of chasing one silver bullet, advising policymakers in South Asia to take a holistic, systems perspective to crop management.
“We know that there are issues relating to water and sustainability, but at the same time we also know that diversifying rice — which is a more stable crop — with other crops is not easy as long as you look at it in isolation,” he explained. “Diversifying crops requires a portfolio of practices, which brings together sustainability, viability and profits.”
With South Asia known as a global “hotspot” for climate vulnerability, and the region’s population expected to rise to 2.4 billion by 2050, food producers are under pressure to produce more while minimizing greenhouse gas emissions and damage to the environment and other natural resources.
“Tackling these challenges requires strong collaborative efforts from researchers, policymakers, development partners and farmers,” said Andrew McDonald, a systems agronomist at Cornell University and co-author of the study. “This study shows this collaboration in action and brings us closer to achieving resilient, nutritious and sustainable food systems.”
“The results of this study show that one-size doesn’t fit all when it comes to sustainable crop management,” said PC Sharma, director of India’s ICAR-Central Soil Salinity Research Institute (ICAR-CSSRI). “Farmers, researchers and policymakers can adopt alternative crop rotations such as maize-wheat or maize-wheat-mung bean, but they can also improve existing rice-wheat rotations using conservation agriculture methods.”
