Can we sustainably harvest trees from tropical forests?

The report, funded by the United States Agency for International Development (USAID) and the US Forest Service International Program, challenges the prevailing notion that logging invariably degrades tropical forests. It proposes a shift from exploitative “timber mining” to a more sustainable “managed forestry” model, emphasizing that poor logging practices are likely to persist in a significant portion of the world’s tropical forests.

The core argument is that responsible forestry can coexist with the conservation of biodiversity, non-timber forest products, and carbon emission reduction. The report outlines five key strategies to improve forest management:

Improve Logging Practices: Implement planned harvest operations by trained workers using lower-impact logging practices to minimize soil erosion, worker injuries, and carbon emissions.

Waste Less Wood: Train workers to maximize wood recovery during harvesting and processing, reducing waste and damage.

Allow Time for Recovery: Extend the intervals between harvests and limit the amount harvested to sustain timber yields and reduce carbon emissions. This approach may lower short-term profits but ensures future timber availability and potentially offers carbon market compensation.

Protect Young Trees: Safeguarding and nurturing small trees, especially in previously logged forests, can enhance future timber yields and double the rate of carbon dioxide removal.

Plant More Trees: Use enrichment planting in areas lacking natural regeneration of commercial species to boost growth and carbon sequestration.

The report underscores that these strategies offer cumulative carbon benefits, making managed forestry a viable candidate for carbon market support. This approach contrasts with anti-logging carbon projects, which might displace logging activities elsewhere. Managed forestry not only aids in carbon sequestration but also generates employment and supports a stable workforce.

For the transition from exploitative logging to responsible forest management, the report calls for support from governments, the private sector, and society. It emphasizes the need for government enforcement of laws to prevent economic and environmental losses due to illegal timber. The forest industry must recognize the value of investing in all aspects of forestry, including maintaining productive timber stands.

Finally, the report highlights a societal role in supporting forestry education and overcoming misconceptions about forest management. The decline in forestry education programs and a shift in focus to plantations over natural forests is a concern. Encouraging the training of young foresters is essential for the transition to responsible forest management, promising financial, environmental, and social benefits.
