Forest Income and Income Inequality: A Gini Coefficient and Lorenz Curve Analysis of Non- Timber Forest Produce Income Across Forest Circles of Chhattisgarh, India
This study analyzes household income data from three forest circles in Chhattisgarh, India, and finds that non-timber forest produce (NTFP) income significantly reduces overall income inequality by 8.35%, acting as a progressive, redistributive livelihood source with varying equalizing impacts across different local contexts.

In the dense, green fringes of India's central forests, a quiet economy thrives that exists largely outside the view of city markets and formal banks. For millions of people living in these forested regions, the trees provide more than just shade; they offer a vital safety net. These communities gather non-timber forest produce, a term that covers everything from wild fruits, flowers, and seeds to resins and leaves, all harvested without cutting down the trees. For many households, selling these items is not just a side activity but a crucial part of their survival, often filling the gaps when crops fail or when cash is needed for daily necessities. While it is well known that these resources support livelihoods, a deeper question has remained unanswered: does this income help level the playing field between the rich and the poor within these communities, or does it simply add to the wealth of those who are already better off? Understanding this distribution is key to knowing whether forest policies are truly helping the most vulnerable families or if they are inadvertently widening the gap between neighbors.
To answer this, researchers traveled to the state of Chhattisgarh, a region in central India where forests cover a vast portion of the landscape and where a large percentage of the population belongs to tribal communities. The team focused on three distinct forest circles—Raipur, Kanker, and Surguja—which represent different types of terrain and varying levels of access to markets. They selected 315 households that rely heavily on collecting these forest products. The researchers did not just ask how much money these families made; they built a detailed picture of every source of income for each household, including money from farming, livestock, and wage labor. Then, they calculated the total income for each family twice: once including the money earned from selling forest products, and once excluding it. By comparing these two scenarios, they could see exactly how the forest income changed the financial landscape of the community.
The results revealed a clear and consistent pattern. When the researchers looked at the income distribution without the money from forest products, the gap between the poorest and the richest households was significant. However, once they added the income from selling forest produce into the mix, that gap shrank noticeably. In the overall group of 315 families, the measure of inequality dropped by more than eight percent. This means that the money earned from the forest did not just add to the total pot of wealth; it flowed disproportionately to the families who had the least to begin with. The Lorenz curve, a visual tool used to map out how income is shared, showed that the line representing the families with forest income sat closer to a perfect balance than the line for those without it. This suggests that for the poorest households, the forest is not merely a supplement but a critical equalizer that helps them catch up to their wealthier neighbors.
However, the story was not exactly the same in every corner of the state. The researchers found that the strength of this equalizing effect depended heavily on how commercialized the local trade was. In the Kanker and Surguja circles, where the trade in forest products is less dominated by large traders and more reliant on local collectors, the impact was profound. In Kanker, the inclusion of forest income reduced inequality by over eleven percent, and in Surguja, the reduction was even sharper at nearly twelve percent. In these areas, the forest income acted as a powerful buffer for the most income-constrained families. In contrast, the Raipur circle told a different story. Here, the trade is more commercialized, with better roads and storage facilities that allow wealthier households with more resources to participate more fully. Consequently, the equalizing effect was much weaker, dropping inequality by only about three percent. In Raipur, the benefits of the forest trade were more evenly spread, but they did not lift the poorest families as dramatically as they did in the other two regions.
These findings offer a nuanced view of how nature supports human economies. The study confirms that for tribal households in Chhattisgarh, income from non-timber forest produce functions as a progressive force, helping to redistribute wealth within the community. It acts as a safety net that is most effective where the market is less developed and where the poorest collectors can access the resources directly. The research suggests that policies aimed at supporting these communities, such as government programs that set minimum prices for forest goods, could be even more effective if they are tailored to the specific conditions of each forest circle. In areas where trade is already commercialized, additional support might be needed to ensure that the poorest collectors are not left behind by market forces. Ultimately, the forest is not just a source of timber or a backdrop for scenery; for the people living on its edge, it is a dynamic economic engine that, when managed with care, has the power to bring families closer together financially.
