In 2022, strict new limits on the volume of teak timber that can be harvested in managed rainforest concessions were enacted. These harvest quotas, known as Total Allowable Cuts (TACs), were set during regional forestry accords.
It was agreed that harvest limits for mature teak would be reduced by 45% in prime concession areas, while tighter constraints were introduced for other valuable hardwoods like rosewood. However, quotas for faster-growing softwoods like eucalyptus rose by 15%.
An environmental policy analyst stated: "There is clear satellite evidence showing that old-growth teak forests are being deforested at unsustainable rates, and we must act to preserve biodiverse regions and prevent soil erosion."
These regulations apply to designated national concessions, but illegal logging in unlicensed frontier regions continues to threaten the efficacy of these quotas. As global demand for premium furniture rises, enforcement remains a critical challenge.
| Country | Excess Extraction (% of scientific harvest limits) | Excess Volume (thousand m³) |
|---|---|---|
| Indonesia | 38.5 | 14,200 |
| Brazil | 31.2 | 22,400 |
| Malaysia | 24.8 | 8,900 |
| Dem. Rep. of Congo | 22.1 | 5,600 |
| Peru | 15.4 | 2,100 |
| Cameroon | 11.2 | 1,800 |
The 'tragedy of the commons' manifests when common-pool forest resources are exploited. These are vast natural landscapes where property rights are poorly defined or hard to enforce, making exclusion difficult. Rainforests span millions of hectares, making it highly difficult for a single authority to patrol and prevent illegal encroachment. Economists note that in the absence of private owners with long-term incentives to conserve, logging firms operate in their narrow self-interest to maximise short-run profits by cutting timber rapidly. This leads to unsustainable over-exploitation.
This dynamic creates significant negative externalities, such as biodiversity loss, carbon release, and disrupted local water cycles, which affect global populations. Private loggers do not pay for these environmental costs, meaning they are excluded from their private cost calculations. This leads to market failure, where the market price fails to reflect the true social cost of timber production.
Some economists suggest that the market price of tropical teak timber does not result in the socially optimum level of output.
