Logging in certified concessions drove intact forest landscape loss in Congo Basin

By Mike Gaworecki
A study published in the journal Science Advances this month found that, between 2000 and 2013, the global area of intact forest landscape declined by 7.2 percent, a reduction of 919,000 square kilometers, or a little over 227 million acres.

Intact forest landscapes (IFLs) are areas of natural land cover that are large and undisturbed enough to retain all their native plant and animal communities — defined at 500 square kilometers. For an IFL to be considered “lost,” its vegetation needs to be degraded to an extent at which it can no longer support its original levels of biodiversity.

Among the study’s other findings, one in particular was quite surprising: Certification of logging concessions, which aims to ensure sustainable forest management practices, had a “negligible” impact on slowing the fragmentation of IFLs in the Congo Basin, home to the world’s second-largest rainforest as well as high levels of biodiversity, including more than 600 tree species and 10,000 animal species.

Which tropical forest conservation strategies are proving most effective?

A collection of studies published by the journal PLOS ONE earlier this month evaluates the effectiveness of numerous tropical forest conservation policies and programs in Africa, Asia, and Latin America.

A multitude of conservation strategies are currently deployed across the tropics in order to curb deforestation, preserve biodiversity, and mitigate global warming. But conservationists and researchers often point to a need for more and better evaluations of the effectiveness of this diversity of conservation initiatives in order to determine what actually works and what doesn’t.

A collection of studies published by the journal PLOS ONE earlier this month seeks to fill this knowledge gap by evaluating the effectiveness of numerous tropical forest conservation policies and programs in Africa, Asia, and Latin America, including certification schemes, community-based forest management, forest law enforcement, payments for ecosystem services, and protected areas.

An overview study led by Jan Börner of Germany’s University of Bonn and the Center for International Forestry Research (CIFOR) focuses on annual forest cover change as a measure of the conservation effects estimated by the 14 studies in the collection. The latest assessment by the UN Food and Agriculture Organization found that Earth’s overall natural forest cover continues to shrink, though at a slower annual rate than in the past. “Reduced deforestation rates may be the result of slower economic growth, decreasing demand for cleared land in urbanizing economies, or a sign that conservation policies are succeeding,” Börner and his co-authors write in the overview study.
