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.
