This study estimates depreciation values for timber extraction activities in the Brazilian Amazon for 1990 and 1995. A generalized approach following Vincent and Hartwick (1997) is applied enabling us to calculate depreciation based on all three methods proposed in the literature. We also calculate Hotelling rents for timber as a whole and for mahogany alone. Apart from the expected differences in the results for each method, the results show substantially low depreciation estimates as a direct consequence of the high timber stocks and scarcity perception by economic agents due to the lack of property rights in the region. For mahogany alone we obtain substantially higher values. We conclude that if scarcity rents are not fully perceived, or they really do not exist in such huge supply conditions as our estimates may suggest, charges related to other forest services are fundamental to make environmental accounting an useful tool for planning in the Amazonian context.

In the red list of threatened species of Pará State, in Brazil, the salamander Bolitoglossa paraensis was listed as vulnerable. Initially the species was considered a synonym with Bolitoglossa altamazonica, but was recently revalidated. This note discusses the validity of the specimens from the west of the Brazilian Amazon identified as B. paraensis. It is also discussed the categorization of the species as vulnerable, and the records of the species was mapped in the Endemism area Belém. In order to establish a Private Natural Reserve (RPPN), a herpetological survey was carried out in different landscape units of the Nova Amafrutas, in Benevides (Pará), and the records of B. paraensis were mapped in these landscape units. By comparing the abundances recorded by Crump (1971) and those results of the present study, suggested that this species is tolerant to antropic “capoeira” forest (old fallows) next to undisturbed forest. More molecular phylogeographic studies are needed in order to establish a stable the taxonomy status for B. paraensis, and also the definition of its real endemic status in the Center of Endemism of Belém.

Sustainable development is among the foremost ideas that guide societal aspirations around the world. This book interrogates the concept through a critical lens, examining both its history and the trajectory of its manifestations in the Brazilian Amazon. The book argues that sustainable development is a concept that is better understood as involving embroilments and ongoing processes of contestation rather than a single end goal. The research offers historical analysis of Amazonian development from the colonial era into the discourse and praxis of sustainable development in contemporary times, and then illustrates the tensions of sustainable development plans that are experienced by people living in the areas geographically the closest to where those plans are being implemented. The history of the Brazilian Amazon is introduced to readers through focused discussions on the tensions between making grand plans for the region and the everyday practices and experiences of sustainable development, which involve considerably more muddling. Case studies explore agrarian reform initiatives that occur alongside road paving projects, the creation of extractive reserves and conservation areas that follow in the wake of assassinations, and the construction of a massive hydroelectric dam. While Amazonian sustainable development is a widely-accepted imperative, the research presented here shows how land use and infrastructure plans conducted in the name of sustainable development often perpetuate and reinforce economic and political inequalities.
