The meeting was organized by TEMNAR Co. Ltd., and brought together key stakeholders including farmers, government officials, research institutes, NGOs, and partners such as Ruvuma Commercialization and Diversification of Agriculture (RUCODIA), SWISSAID, and Vodacom. All participants affirmed the meeting’s overall impact and significance, acknowledging that the event would help lay a strong foundation for the growth of groundnut farming, particularly in Mtwara and Lindi regions.
The meeting featured presentations from scientists at the Tanzania Agricultural Research Institute (TARI) — who addressed topics such as groundnut agronomy and seed technology — and representatives from TEMNAR, who outlined strategies to facilitate effective collaboration among stakeholders and achieve mutually beneficial outcomes. Discussions centered on topics such as groundnut varieties, market demands, and the importance of quality and cleanliness throughout the production process. Trust in business relationships was identified as a key factor for success.
Participants at the meeting shared innovative ideas and identified opportunities for strengthening the sector. They highlighted, for example, the need for aggregators to specify their groundnut volume requirements and the application of simple technologies — such as hand push planters and threshing machines — to increase production efficiency. They also emphasized the importance of planting new TARI-bred groundnut varieties to meet market demand, and the establishment of additional seed multiplication farms to increase seed availability.

Another key component of the meeting was assessing the challenges faced by local groundnut farmers. These include the shortage of good groundnut seed, limited agronomical knowledge, and the labor-intensive nature of planting, harvesting, and picking the crop. To address these challenges, participants suggested making agricultural inputs and tools more accessible to farmers, conducting technology demonstrations, and establishing seed multiplication farms across different districts.
Both farmers and aggregators expressed their commitment to making changes in their farming practices; aggregators are now able to access groundnuts easily through phone calls, while farmers enjoy improved access to markets and better prices. A number of follow-up actions have also been planned as a result of the meeting, such as product buyback initiatives during the harvest season and the establishment of field days to help reach more farmers and aggregators at the local level.
In Nepal, the International Water Management Institute and CIMMYT conducted research on Sustainable Intensification of Mixed Farming System (SI-MFS) in collaboration with local governments in Gurbakot Municipality of Surkhet and Haleshi Tuwachung Municipality of Khotang.
The research found a noticeable shift in farmers’ interest in farming practices, where successful implementation of innovation and scaling, it’s crucial to have farmers’ interest and ownership in interventions.

Timothy Reeves, who served as director general of the International Maize and Wheat Improvement Center (CIMMYT) from 1995 to 2002, has been included in Queen Elizabeth II’s Birthday Honours List. He has been appointed a Member (AM) of the Order of Australia, for his significant service to sustainable agriculture research and production.
“I’m overwhelmed. I feel so honored and wish to also recognize the wonderful people that I have worked with — both farmers and scientists — here in Australia, and around the world. I also acknowledge my beautiful family without whom it would have not been possible,” he said.
Reeves was a pioneer of direct drilling and conservation agriculture in Australia in the 1960s and 70s. This method of planting crops which requires no cultivation of the land, is now the direct-drilling method used by 90% of farmers across Australian cropping regions. He and colleagues in the Victorian Department of Agriculture also worked at that time on the introduction of new crops into farming systems, including lupins, canola and faba beans.

He was appointed to the role of director general of CIMMYT in 1995, based in Mexico for seven years, helping developing countries with food and nutritional security. He is the only Australian to have held this position.
Reeves is currently an Honorary Professorial Fellow at the Faculty of Veterinary and Agricultural Sciences, University of Melbourne. He is heavily involved with passing on his knowledge to his academic colleagues and to both undergraduate and postgraduate students. Reeves’s academic writings include publishing more than 180 papers, book chapters and articles. He is also a Chair of the Agriculture Forum of the Australian Academy of Technological Sciences and Engineering.
South Asia was the epicenter of the Green Revolution, a historic era of agricultural innovation that fed billions of people on the brink of famine.
Yet despite the indisputably positive nutritional and developmental impacts of the Green Revolution of the 1960s, the era of innovation also led to the widespread use of farming practices—like intensive tilling, monoculture, removal and burning of crop residues, and over-use of synthetic fertilizer—that have a deleterious effect on the soil and cause off-site ecological harm. Excess pumping of irrigation water over decades has dried out the region’s chief aquifer.
South Asia’s woes illustrate the environmental costs of intensive food production to feed our densely-populated planet. Currently, one billion hectares of land worldwide suffers from degraded soils.
The International Maize and Wheat Improvement Center (CIMMYT) works with two of the world’s most widely cultivated and consumed cereal crops. To grow enough of these staple foods to feed the world, a second Green Revolution is needed: one that avoids the mistakes of the past, regenerates degraded land and reboots biodiversity in farm areas.
M.L. Jat, a CIMMYT Principal Scientist, has spent 20 years studying and promoting sustainable agricultural practices for maize- and wheat-based farming systems. In the following Q&A, Jat tells us about regenerative agriculture: integrated farming and grazing practices intended to rebuild soil organic matter and restore degraded soil biodiversity.
Q: What major components or practices are part of regenerative agriculture?
A: Regenerative agriculture is a comprehensive system of farming that harnesses the power of soil biology to rebuild soil organic matter, diversify crop systems, and improve water retention and nutrient uptake. The depletion of biodiversity, degradation of soil health, warming, and drier weather in farm areas have necessitated a reversal in agriculture from “degeneration to regeneration.”
The practices address food and nutritional security challenges while protecting natural resources and lowering agriculture’s environmental footprint, in line with the United Nations Sustainable Development Goals. CIMMYT has worked for years to research and promote conservation agriculture, which contributes to the aims of regenerative agriculture, and is already practiced on more than 200 million hectares globally — 15% of all cropland — and is expanding at a rate of 10.5 million hectares per year.
Q: What are the potential roles of major food crops — maize, rice, and wheat — in regenerative agriculture systems?
A: Regenerative agriculture is “crop neutral;” that is, it is applicable to almost all crops and farming systems. The world’s rice, wheat, and maize crops have an enormous physical and ecological footprint on land and natural resources, but play a critical role in food and nutrition security. Considering that anthropogenic climate change has reduced the global agricultural total factor productivity by about 21% in the past six decades, applying regenerative agriculture approaches to these systems represents a momentous contribution toward sustainable farming under increasing climatic risks.
Q: What elements or approaches of regenerative agriculture are applicable in India and how can they be applied?
A: Regenerative practices for maize and wheat systems in India include no-tillage, crop residue recycling, legume inter-cropping and cover crops, crop diversification, integrated nutrient management, and precision water management.
The potential area of adoption for regenerative agriculture in India covers at least 50 million hectares across a diversity of cropping systems and agroecologies — including irrigated, rainfed, and arid farmlands — and can be approached through appropriate targeting, investments, knowledge and capacity enhancement, and enabling policies.
In the breadbasket region of the Indo-Gangetic Plains, regenerative agriculture can help address the aforementioned second-generation problems of the Green Revolution, as well as contributing to the Indian government’s Soil Health Mission and its COP26 commitments.
Q: In order to get regenerative agriculture off the ground in South Asia, who will be involved?
A: Adapting and applying regenerative agriculture’s portfolio of practices will require the participation of all stakeholders associated with farming. Application of these principles is location- and situation-specific, so researchers, extension functionaries, value chain actors, philanthropists, environmentalists, NGOs, farmers, and policy planners all have a role to play in the impact pathway.
CIMMYT, the Borlaug Institute for South Asia (BISA), public and private programs and agencies, and farmers themselves have been developing, refining, and scaling out conservation agriculture-based regenerative agriculture practices for some three decades in South Asia. CIMMYT and BISA will continue to play a key role in mainstreaming regenerative agriculture in local, national, and regional development plans through science-based policy and capacity development.
Q: Farmers constitute a strong economic and political force in India. How can they be brought on board to practice regenerative agriculture, which could be more costly and knowledge-intensive than their current practices?
A: We need to pursue business “unusual” and harness the potential opportunities of regenerative agriculture to sequester soil carbon and reduce greenhouse gas emissions. Regenerative agriculture practices can offer farmers additional income and certainly create a “pull factor” for their adoption, something that has already started and will constitute a strong business case. For example, innovative business models give farmers an opportunity to trade ecosystem services and carbon credits through repurposing subsidies and developing carbon markets for private sectors. CIMMYT, along with the Indian Council of Agricultural Research and private partners such as Grow Indigo, are already helping to put in place a framework to acquire carbon credits through regenerative agriculture in India.
Farmers frequently encounter trade-offs between maximizing short-term profits and ensuring sustainable, long-term production. Santiago López-Ridaura, a senior scientist at the International Maize and Wheat Improvement Center (CIMMYT), says these trade-offs are even more complicated for small-scale farmers who grow a mix of crops and raise livestock. With computer models to play out different scenarios, he and his team are helping them find optimal solutions.
“If you have $100, one hectare of maize, a half hectare of beans and three cows, you have limited resources,” indicates López-Ridaura. “You have to decide how you allocate those resources.”
Should the farmer use the money to buy new equipment or vaccinate the cows? What would happen if the farmer replaced the half-acre of beans with maize? These trade-offs, López-Ridaura explains, are one aspect of a farming system’s complexity.
“The other is that these farmers are trying to satisfy multiple objectives,” he adds. “They want to generate income. They want to produce enough food to feed their family and they may be trying to maintain cultural values.”
For example, a hybrid maize variety may produce higher yields under certain growing conditions, but the farmer could decide to continue growing the native variety because it carries cultural or even religious importance. Seasonal migration for off-farm jobs, climate change and access to markets are just some of the other factors that further complicate the decision-making process. López-Ridaura points out many models in the past have failed to capture these complexities because they have focused on one objective: productivity at the plot level.
“Our models show the bigger picture. They take a lot of time to develop, but they’re worth it,” says López-Ridaura.
Custom solutions to farming challenges
The models start with hundreds of in-depth household surveys from a specific region. López-Ridaura and his team then organize the large pool of data into several categories of farming systems.
“We make a model that says, ‘OK, this farm in Oaxaca, Mexico, has five hectares, 20 sheep and five people,” he explains. “We know how much the animals need to eat, how much the people need to eat, how much the farm produces and how much production costs.”
He and his team can then adjust certain factors in the model to explore different outcomes. For example, they can see how much water the farmer could use for irrigation to maximize his/her yields without depleting the local water supply during a drought. They can see which farmers would be the most vulnerable to a commodity crop price drop or who would benefit from a new policy.

“The political guys often want a simple solution so they may say, ‘We should subsidize inputs such as seeds and fertilizers.’ In Mexico, for example, you might miss 60-70% of farmers as they don’t use much of these inputs,” López-Ridaura says. “So that’s great for 30% of the population, but why don’t we think about the other 70%? We must be able to suggest alternatives from a basket of options, considering the diversity of farming systems.”
López-Ridaura emphasizes that the models on their own do not provide solutions. He and his research team work with farmers to learn what they identify as their main challenges and how best to support them.
“We have networks of farmers in Guatemala and Oaxaca, and some may say, ‘Well, our main challenge is being self-sufficient with forage crops,’ and we’ll say, ‘OK, why don’t we try a crop rotation with forage crops? Our model suggests that it might be an appropriate option.’”
He and his team can then help the farmers access the right kind of seed and find out how best to grow it. This relationship is not a one-way street. The farmers also provide feedback on what is or is not working on the ground, which helps the researchers improve the accuracy of their models. This approach helps the researchers, farmers and policymakers understand different pathways forward and develop locally adapted, sustainable solutions.
