Beyond Monoculture: How Integrated Farming Is Reviving Northeast India’s Farms
For decades, many small and marginal farmers across Northeast India followed a familiar and increasingly costly path. Commercial crops and chemical inputs were promoted as the route to higher yields and better incomes. Herbicides became routine as labour costs rose and weeds flourished under the region’s heavy rainfall. Over time, production costs climbed, pests grew harder to manage, soils weakened, and returns turned uncertain. Disease outbreaks repeatedly damaged harvests. Farmers who once grew diverse local crops shifted toward cash crops such as areca nut and horticultural plantations in search of stability, only to find the soil losing strength and beneficial insects growing scarce.
Swapna Marak, a 43-year-old farmer in Paschim Satgaon village of Assam’s Nagaon district, lived this reality. Standing beside her fishpond and gesturing toward the vegetable patch, pig shed and poultry unit that now surround it, she recalls the earlier insecurity. “Earlier, if one crop failed, everything failed,” she says. “We spent more every season but earned less.” Her experience mirrors a larger shift that unfolded across the region. As monoculture expanded, farms became more dependent on external inputs and more vulnerable to climate shocks, pest outbreaks and volatile markets. Today, farmers like Marak are deliberately reversing that trajectory. They are reconnecting crops, livestock, fish and water systems so that the output of one component becomes the input for another.
Integrated Farming Systems, or IFS, treat the farm as a single living ecosystem rather than a collection of isolated enterprises. Vegetables, fishponds, pigs, poultry, trees and water management operate in deliberate synergy. Animal waste becomes manure for crops and ponds. Crop residues feed livestock. Pond water irrigates vegetables during dry spells. Nutrients remain circulating within the landscape instead of leaving as waste or pollution. The result is a closed-loop system that reduces the need for expensive external fertilisers and pesticides while spreading risk across multiple income streams.
Patai Boro, a lead farmer from Khatarbari village in Assam’s Tamulpur district, explains the principle simply. “The idea is to keep resources circulating within the farm. Animal waste becomes manure for crops and fishponds. Crop residues feed livestock. Pond water irrigates vegetables during dry periods. Instead of treating everything separately, the farm works like one ecosystem.” His wife, Mina Boro, adds that the change has eliminated much of the earlier waste. “Now nothing is wasted. Every part of the farm has value.”
This approach is being actively promoted under the Joint Initiative for Village Advancement (JIVA) programme in parts of Assam and Arunachal Pradesh. Supported by NABARD and guided technically by the Watershed Support Services and Activities Network (WASSAN) in collaboration with the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), the initiative works through local organisations such as Kalong Kapili and Gramya Vikash Mancha in Assam, and the NOSAAP Producer Company in Arunachal Pradesh. Beyond introducing integrated models, the programme strengthens farmer-to-farmer extension through trained lead farmers and encourages local production of bio-inputs. The goal is to help smallholders diversify production while steadily reducing dependence on external chemical inputs.
For these farmers the most immediate advantage is the spreading of risk. Income now arrives from different sources throughout the year. Vegetables provide regular harvests, fish are sold seasonally, and pigs and poultry generate additional earnings. “Even if one enterprise performs poorly, others help sustain the household,” Marak notes. The psychological relief of no longer depending on a single crop is as significant as the financial one.
The ecological benefits are equally visible. In Samuguri village of Nagaon district, farmer Ranjit Rabha no longer regards fishponds merely as places to raise fish. “They store water for irrigation, and their bunds grow vegetables and fodder,” he says. Around the ponds, naturally occurring taro, fiddlehead ferns and other edible plants thrive alongside cultivated crops. Livestock manure enriches both soil and water, reducing the need for chemical fertilisers. Nutrients stay within the system rather than leaching away.
The same pattern appears further east. Dipika Sonowal, a farmer from Jona Kachari village in Arunachal Pradesh’s Namsai district, observes that vegetable gardens, trees, ponds and livestock together support far richer biodiversity than monoculture landscapes. Birds, insects, fish and soil organisms that had largely disappeared begin to return. Healthier ecosystems become an economic asset. Across project villages, farmers report that diversified farms cope better with erratic rainfall and temperature extremes while requiring fewer costly external inputs.
In many respects the shift represents a revival of practices long embedded in the region’s indigenous knowledge systems. “Our elders always believed every part of the farm should support another,” Sonowal says. “We are simply learning that lesson again.” Traditional systems such as the integrated rice-fish cultivation of the Apatanis in Arunachal Pradesh or the multi-layered jhum fallows that once allowed soil recovery are finding contemporary expression in modern IFS models adapted to today’s land pressures and market needs.
Research and field experience across the Northeast reinforce these farmer observations. Pond-based integrated farming models tested in Meghalaya have shown system productivity rising by approximately 7.5 times and profitability by about 8.5 times compared with traditional practices, with benefit-cost ratios around 2.7. Long-term Integrated Organic Farming System models developed by the ICAR Research Complex for the North Eastern Hill Region at Umiam have recorded rice-equivalent yields several times higher than monocropping while meeting most of the farm’s nutrient requirements from within the system itself through composting, livestock manure and crop residues. Similar results appear in Nagaland, Manipur, Tripura and other states, where women-led farms combining field crops, horticulture, piggery, fishery, poultry and small-scale value addition generate year-round income and markedly reduce production risk.
Multi-layer cropping and agroforestry are also gaining ground as practical ways to convert exhausted jhum lands into more productive, climate-resilient systems that simultaneously store more carbon and protect slopes from erosion. These approaches align with broader efforts to position Northeast India as a hub for quality-focused, sustainable and organic agriculture rather than volume-driven commodity production. Recent policy emphasis on organic spice processing, farmer producer organisations and natural farming further supports the transition.
Challenges remain. Limited technical knowledge, high initial costs for some components, and weak market linkages for diversified produce still constrain wider adoption. Yet the direction of change is clear. As climate uncertainty intensifies across the hills and valleys of the Northeast, many farmers are concluding that long-term resilience does not come from maximising a single crop. It comes from rebuilding farms as connected ecosystems in which crops, animals, water and biodiversity reinforce one another.
The farms of Swapna Marak, Patai and Mina Boro, Ranjit Rabha and Dipika Sonowal illustrate what that rebuilding looks like in practice. They are not simply returning to the past. They are adapting enduring ecological principles to the economic and climatic realities of the present—one integrated farm at a time. In doing so, they are demonstrating that diversity, once again, can be the most reliable form of security for both households and landscapes.
