An integrated framework for harmonizing definitions of deforestation.

• There is currently no consensual definition on deforestation. • Existing definitions are not functional in decision-making contexts. • We propose a common framework as a tool to harmonize deforestation definitions. There is currently no consensual definition of deforestation. Given its importance in several research topics ranging from biodiversity to climate change, conservation, restoration, and emerging diseases as well as in comparative studies, it is necessary to provide an integrated framework towards a harmonized definition of deforestation. Here, we analyze and compare international and national reports on deforestation management (e.g., FAO, UNFCCC) and find important differences, including contrasting definitions of deforestation and conceptual ambiguities. We also present a straightforward, harmonized definition of deforestation that is linked to a specific methodology for decision-making studies. This proposal can contribute to informed decision-making on studies related to deforestation. [ABSTRACT FROM AUTHOR]
