Forests are the best case studies for economic excellence

The Oldest Economy on Earth

Walk into a mature sal forest in central India and nothing seems to be happening. Yet beneath the stillness runs one of the most efficient economies ever assembled. Sunlight is captured by a layered canopy so that little is wasted; fallen leaves become food for fungi and termites; fungi trade minerals with tree roots in exchange for sugars; and every waste becomes someone else's input. This economy has run for millions of years without a central bank, a balance sheet or a bailout, and it has survived ice ages, fires and droughts. If economic excellence means creating lasting value from scarce resources while staying resilient to shocks, then the forest is the most instructive case study we have. The forest teaches in two ways: as a model whose principles human economies can borrow, and as an asset whose true worth our economies have long failed to count.

The first lesson is efficiency without waste. A forest has no landfill. Every leaf, carcass and fallen log is broken down and recycled into nutrients, a closed loop that economists now call the circular economy. Ecologists distinguish the one-way flow of energy, part of which every food chain loses as heat, from the cycling of nutrients, which a healthy forest returns to the soil almost completely. Human industry, by contrast, has long followed a linear path of take, make and throw away. When India framed rules on extended producer responsibility for plastic packaging and e-waste, it was in effect asking manufacturers to behave like a forest floor, taking responsibility for what their products become after use.

The second lesson is the strength of diversity. A natural forest holds hundreds of species, so that the failure of one does not collapse the whole. A monoculture plantation, however productive in a good year, can be wiped out by a single pest. Economies behave the same way. Countries that depend on one commodity suffer when its price crashes, as oil exporters learned in 2014, while diversified economies absorb shocks more easily. The same principle guides an investor's portfolio and a farmer's mixed cropping. The Covid-19 pandemic exposed how global supply chains concentrated in a few places could break, and India's push for diversified manufacturing through schemes such as production-linked incentives reflects the forest's quiet wisdom that variety is insurance.

The third lesson is that competition and cooperation coexist. Trees compete fiercely for light, yet beneath the soil they share resources through mycorrhizal fungal networks that the forest ecologist Suzanne Simard has studied for decades, a web through which nutrients can move between trees. An excellent economy similarly combines market competition with cooperative institutions. India's own experience offers proof: the Amul cooperative, which grew out of the Kaira District milk union in 1946, allowed millions of small dairy farmers to compete with large firms by pooling their strength. Self-help groups under the National Rural Livelihoods Mission do the same for rural women. Like the forest, the strongest economies are neither ruthless jungles nor collective farms, but a balance of the two.

The fourth lesson is about time. A forest grows by succession: grasses yield to shrubs, shrubs to pioneer trees, and pioneers to a climax community over decades. It invests patiently, storing carbon and soil for the long run. Fire, too, plays its part; some pine cones open only in heat, so that a burnt patch is reseeded. Joseph Schumpeter described capitalism as a process of creative destruction, in which old firms make way for new ones. The forest shows that renewal after disruption is healthy when the deeper capital, the soil and the seed bank, is preserved. Economies that protect their human capital through education and health recover from recessions; those that consume it for short-term gain do not.

Beyond the metaphor lies a harder truth: forests are themselves an economy of enormous, mostly uncounted value. India's forest and tree cover stood at 25.17 per cent of its geographical area in the India State of Forest Report 2023. These forests regulate rivers, recharge aquifers, hold soil and store carbon, and India's climate pledge counts on them to create an additional carbon sink of 2.5 to 3 billion tonnes of carbon dioxide equivalent by 2030. Yet none of this appears in GDP until a tree is felled. The Dasgupta Review on the economics of biodiversity, published by the UK Treasury in 2021, argued that nature is an asset and that an economy which runs down its natural capital is growing poorer even as its measured income rises. The study The Economics of Ecosystems and Biodiversity, led by Pavan Sukhdev, made the same case a decade earlier.

Forests are also a living economy for people. Tens of millions of Indians, many of them Adivasis, depend on forests for food, fuel, fodder and income from minor forest produce such as tendu leaves, bamboo and mahua. When Mendha Lekha village in Gadchiroli gained community rights over its bamboo under the Forest Rights Act, 2006, its gram sabha began selling bamboo itself and reinvesting the income in the village, a model of local, sustainable enterprise. The Chipko movement of the 1970s in the Garhwal Himalaya showed that villagers understood the economic value of standing trees long before planners did. Even the Arthashastra provided for a superintendent of forest produce, the kupyadhyaksha, recognising forests as a source of state wealth to be managed, not merely exploited.

The evidence of forests as economic infrastructure is striking. A study by Saudamini Das and Jeffrey Vincent found that villages in Odisha shielded by mangroves suffered fewer deaths in the 1999 super cyclone, showing that a natural buffer can do the work of a costly sea wall. Costa Rica, which began paying landowners for ecosystem services in the late 1990s, reversed decades of deforestation while building a thriving ecotourism industry. India's Compensatory Afforestation Fund Act, 2016 and the Green India Mission try to put a price on what is lost when forests are diverted, though critics rightly note that a new plantation is no substitute for an old, diverse forest.

Yet the analogy has limits, and honesty requires us to name them. Forests do not pursue growth for its own sake; they reach a steady state, while modern economies are built on expansion. Nature can also be brutal, with no safety net for the weak, and no society would accept that as its model of justice. Moreover, treating forests merely as economic assets carries its own danger: the colonial forest department valued teak and sal for timber and railway sleepers, cleared mixed forests for plantations and excluded forest dwellers, which was efficient for revenue but ruinous for ecology and people. Excellence, then, cannot be measured only in rupees.

The forest's true lesson is that excellence lies not in maximising output but in sustaining life, and an economy that grasps this will prosper for longer. It is efficient because it wastes nothing, resilient because it is diverse, strong because its members cooperate as well as compete, and patient because it invests for generations. As India aims to become a developed nation by 2047, it must learn from the forest twice over: by building an economy that copies these principles, and by counting the forest's own wealth in its national accounts. The silent sal grove is not a resource waiting to be used. It is a teacher, and its classroom has been open for millions of years.
