Population pressures play less of a role in deforestation than earlier studies of Thailand found. Between 1976 and 1989, Thailand lost 28 percent ofits forest cover. To analyze how road building, population pressure,and geophysical factors affected deforestation in Thailand during that period, Cropper, Griffiths, and Mani develop a model in whichthe amount of land cleared, the number of agricultural households,and the size of the road network are jointly determined.The model assumes that the amount of land cleared reflects an equilibrium in the land market.

A recent eighteen-month economic study of the benefits of alternative uses of forest and in Ratanakiri province recommends the exclusion of customary forest land from current and future commercial concessions. The study compares the economic benefits of using forest land in Ratanakiri for the traditional collection of non-timber forest products by ethnic communities, with the benefits of commercial timber harvesting. The main conclusions of the study are that non-timber forest products (NTFP) are worth a lot, much more than previously thought.

Social forestry emerged amidst important changes in thinking about the role of forestry in rural development and a growing need for fuelwood. In an attempt to alleviate the fuelwood crisis, the World Bank encouraged the planting of Eucalyptus species in its social forestry programs in the 1980s. Eucalypts were the chosen tree species for the majority of social forestry projects because they survive on difficult sites and out-perform indigenous species and most other exotics in height and girth increment, producing wood for poles, pulp and fuel more rapidly.

The overall aim of the National Land Policy is to promote and ensure a secure land tenure system, to encourage the optimal use of land resources, and to facilitate broad-based social and economic development without upsetting or endangering the ecological balance of the environment. The specific objectives of this National Land Policy are to: promote an equitable distribution of and access to land by all citizens; ensure that existing rights in land especially customary rights of smallholders (i.e.
