Can non-market values save the tropical forests?

摘要: It seems fair to say that, from a world standpoint, forestry is in crisis. While it would be foolish complacent — the historical evidence of social collapse due deforestation all too stark (Perlin, 1989) there little that current supply timber scarce, and will become scarce near-term (Sedjo Lyon, 1990; Hyde et al., 1991). But concern non-timber functions forests are becoming increasingly (Krutilla, 1967; Panayotou Ashton, 1993). Those include maintenance biological diversity, carbon sequestration, local products, environmental protection, broader life support functions, recreational use, ‘passive value’ value independent any use now or foreseeable future. The clue simultaneous condition scarcity and, if not abundance then adequacy, lies fact as much product type forest they geographical extent forests. Biodiversity, for example, appear function heterogeneous rather than uniform ones, although hard-and-fast rule. crisis is, then, loss, easy see such could emerge almost unnoticed where, until recently, policy was determined by commercial interests alone.
