    This paper begins by discussing Tanzania's increasing recognition of the need to bring individuals, local groups, and communities into the policy, planning, and management process if woodlands are to remain productive in the coming decades.The article finds that:central control of forests takes management responsibility away from the communities most dependent on them, inevitably resulting in tensionsTanzania has enthusiastically established community-owned and -managed forest reservesthe most successful initiatives involving communities and individuals have been those that moved away from

    This article discusses the extent to which the location of roads s and protected areas affects deforestation in North Thailand. The article stresses that establishing protected areas (national parks together with wildlife sanctuaries) in North Thailand did not reduce the likelihood of forest clearing, but wildlife sanctuaries may have reduced the probability of deforestation.

    Road network expansion is strongly associated with increased deforestation in the Brazilian Amazon. Pfaff analyzes the determinants of deforestation in the Brazilian Amazon. Using a model of optimal land use, he derives and estimates an equation for deforestation using (1) country level data for 197888 and (2) measures of deforestation from satellite images.The evidence suggests that: Increased road density in a county leads to more deforestation there and in neighboring counties. Development projects were associated with deforestation in the 1970s but not in the 1980s.

    Will intensifying the road network around market areas produce greater economic returns and less environmental damage than extending the road network into new areas?Rural roads promote economic development but also facilitate deforestation. To explore the trade-offs between development and environmental damage posed by road building, Chomitz and Gray develop and estimate a spatially explicit model of land use.

    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.
