Recent forest expansion in Thailand: A methodological artifact?

Abstract

Several Asian developing countries recently reported a net increase in forest cover. In Thailand, such reports have been vehemently rejected by forest officials, researchers, politicians, and international organizations alike. According to the dominant interpretation, the apparent forest regrowth derives from a methodological artifact. While the determination of the true evolution of forest cover has important implications, this interpretation has never been subject to scrutiny. This article presents a broad range of data and analyses suggesting important flaws in this interpretation. Based notably on (1) a critical review of available forest statistics and the methodology used to produce these statistics, (2) case study material from northern Phetchabun Province, and (3) an analysis of recent sub-national remote-sensing surveys, we reject the dominant interpretation of official statistics and suggest that reforestation has increased in Thailand and plausibly became the overall trend in the late 1990s. © 2013 © 2013 Taylor & Francis.
