| Recent popular ideas and theories portray economic development as both a cause and a solution to environmental degradation. Concerning forest cover, many authors view forest transitions (the passage from deforestation to reforestation) as resulting from near-universal causal dynamics linked to economic development. The thesis evaluates the validity of these controversial ideas and their relevance to the Thai case.;Based on an analysis of secondary literature and official data as well as extensive fieldwork in Phetchabun region, the thesis makes the following points. Contrary to the dominant view, forest cover did expand significantly between ~1995 and 2005. Forest regrowth is linked to the near-interruption of agricultural expansion, the establishment of forest plantations, and, most importantly, agricultural abandonment. The latter derives first and foremost from the declining and currently uncertain profitability of agriculture in non-irrigated zones. These agricultural problems are linked to declining soil fertility and the incapacity of some farmers to counter the impact of rapid economic changes occurring within and outside Thailand. Conservation efforts contributed to forest expansion only in some contexts (ex.: military-backed projects, divided communities, land already abandoned). Agricultural intensification and the growth of non-agricultural sectors made land confiscation and agricultural abandonment less distressing and allowed these land transformations to occur without leading to major social troubles. Since 2005, part of the forest regrowth has been lost to the rubber boom. This illustrates both the potentially nonpermanent nature of the forest transition and the limited power of forest conservation in the face of major politico-economic interests.;A robust forest transition theory must be contextually-bounded and recognize that forest transitions can be encouraged, blocked or countered by the same frequently invoked macro-social variables: economic growth, agricultural intensification, and democratisation. It must also take into account neglected causal factors, such as geopolitical threats, the resilience of agrarian systems, the perception of land scarcity and the degree of attachment to the land and an agrarian life. Typically, social distress, violence and, in some cases, negative environmental impacts have accompanied forest transitions. Human rights, social justice and sustainable development principles require that a more nuanced view of forest transitions be adopted.;Keywords : Environment, development, forest transition, agricultural abandonment, deagrarianisation, forest conservation, protected areas, causality, Thailand... |
