Input – Output balance: PRw+PRwIll+IRwL+IRwIll = PPr+ERw with: PRw = legal production of roundwood PRwIll = illegal production of roundwood IRwL = legal imports of roundwood IRwIll = illegal imports of roundwood PPr = production of processed wood ERw = exports of roundwood Displacement = IRwL+IPrL+IRwIll with: IPrL = legal imports of processed wood The forestry sector in Vietnam Meyfroidt & Lambin, PNAS , 2009

Notas del editor
- Finally, by selecting the most consistent remote sensing data for the 1990s, combined with a critical analysis of other statistical and map sources for previous and further periods, we could reconstitute the forest cover trends in Vietnam for the last decades. This showed that a forest transition most likely occured in Vietnam during the 1990s, with the turning point around 1991-1993.
- Conclusion.
- !! Keep these three ideas in mind: Policies regarding domestic supply, Economic growth creating demand, Imports and displacement.
- Imports of processed wood: pulp and paper, boards, sawnwood. Trucks loaded with illegal timber crossing the Cambodia – Vietnam border.
- Displacement = total volume of wood consumed in Vietnam or transformed and exported from Vietnam, but extracted from forests in other countries. Imports of SPWP: 10-3 times other flows.
