Agro-economic Potential of Agroforestry Practices in the Imphal Valley of Manipur, Northeast India
This study evaluates the agro-economic potential of various agroforestry models in Manipur's Imphal Valley, revealing that while home gardens are the most widely adopted for food security, fish- and livestock-integrated systems yield the highest economic returns, highlighting a significant trade-off between on-farm biodiversity and short-term profitability.

In the Imphal Valley of Northeast India, the land tells a story of tight constraints and deep tradition. This valley is a flat, fertile bowl surrounded by steep hills, home to a dense population where the soil is precious and the seasons bring heavy rains that often wash out the roads. Here, farming is not just about growing rice; it is a complex survival strategy where families weave together trees, vegetables, livestock, and fish on the same small plots of land. This practice, known as agroforestry, is a way of mixing different types of life to create a safety net. It provides food when markets are cut off, offers income when crops fail, and preserves a rich variety of plants that have been grown by local communities for generations. The question facing researchers and policymakers is simple but critical: in a place where every square meter of land counts, which of these mixed farming systems actually works best for the people who rely on them? Do the systems that hold the most variety of plants also bring the most money, or is there a trade-off between keeping nature diverse and keeping a household fed?
To find the answer, a team of researchers from Manipur University traveled across the Imphal Valley, visiting villages in both the eastern and western districts. They did not just look at the fields from a distance; they walked through them, counting the trees, listing the vegetables, and noting the animals. They spoke with 120 farm families, asking detailed questions about how much land they used, what they planted, what they sold, and what they kept for their own tables. The researchers mapped out the specific combinations of life these farmers use, from simple home gardens filled with vegetables and fruit trees to complex systems that integrate fish ponds with crops and livestock. They then calculated the economic return of each system, comparing the total value of what the farm produced against the cost of the seeds, labor, and feed required to grow it. This approach allowed them to see not just what was growing, but what was actually paying off for the families living there.
What they discovered was a landscape of distinct choices, each with its own strengths. The most common system, adopted by nearly half the families in the western district and a third in the eastern, was the home garden. These are small, intimate plots right next to the house, packed with a wide array of vegetables, fruits, and medicinal plants. They are the backbone of daily life, feeding the largest number of family members per unit of land. However, when the researchers looked at the pure financial return, these gardens were modest. They provided security, but they did not generate a large surplus of cash. In contrast, the systems that included fish farming, where ponds were integrated with crops and trees, were far less common. Only a handful of families had taken on the higher costs and technical demands of raising fish. Yet, these were the clear winners when it came to money. The fish-integrated systems returned significantly more profit for every rupee spent than the plant-only systems.
This finding revealed a surprising tension at the heart of the valley's agriculture. The researchers found a clear pattern: the more plant species a farm had, the lower its immediate cash profit tended to be. The farms with the highest number of different trees and crops were the ones that supported the most diverse diets and the most family members, but they generated the lowest financial returns. Conversely, the farms that made the most money were the ones with fewer plant species, focusing instead on the high value of fish and livestock. It is as if the farmers are balancing two different scales: one for the richness of life and the security of the family table, and another for the hard currency needed to buy goods that cannot be grown. The data showed that this was not a matter of one system being "better" than the other in a general sense, but rather that they serve different, vital purposes. The diverse gardens act as a shield against hunger and preserve the unique food culture of the region, while the fish-integrated systems act as an engine for cash income.
The study also highlighted why the most profitable systems are not the most popular. Despite the fish farms bringing in more money, they were not the choice for the majority of families. The researchers noted that these systems require more upfront money to build ponds and buy fish, and they demand more technical skill to manage. For many families, especially those led by women who make up a large portion of the households surveyed, the risk and cost are simply too high. The home garden, with its low cost and immediate food rewards, remains the default choice for survival. The researchers concluded that the path forward for the valley is not to force everyone to switch to the most profitable model, but to recognize the value of both. They suggest that support should be given to help families who want to try fish farming by providing credit and training, while simultaneously protecting and improving the home gardens that keep the region's food culture and biodiversity alive. In a landlocked valley where roads can disappear for days, this dual approach offers a way to build a future that is both rich in life and secure in income.
