15 صفحه اولTemporal Decay in Timber Species Composition and Value in Amazonian Logging Concessions
Throughout human history, slow-renewal biological resource populations have been predictably overexploited, often to the point of economic extinction. We assess whether and how this has occurred with timber resources in the Brazilian Amazon. The asynchronous advance of industrial-scale logging frontiers has left regional-scale forest landscapes with varying histories of logging. Initial harvest...
متن کاملTimber Cycles *
We construct an intertemporal model of rent-maximizing behaviour on the part of a timber harvester under potentially multi-dimensional risk as well as geographical heterogeneity. Subsequently, we use recursive methods (in particular, the method of dynamic programming) to characterize the optimal policy function, the rent-maximizing timber-harvesting profile. One noteworthy feature of our applic...
متن کاملNumerical Modelling of Timber Braced Frame Masonry Structures (Dhajji Dewari)
This paper presents numerical modeling technique for Dhajji-Dewari structures (timber-braced rubble stone masonry), and its application for the evaluation of in-plane force-deformation capacity of Dhajji wall panels of different configuration of bracings. Dhajji structures are mainly composed of vertical and horizontal timber posts and braced using diagonal bracings and horizontal studs. Wall o...
متن کاملTimber Management Planning with Timber RAM and Goal Programming
By using goal programming to enhance the linear programming of Timber RAM, multiple decision criteria were incorporated in the timber management planning of a National Forest in the southeastern United States. Combining linear and goal programming capitalizes on the advantages of the two techniques and produces operationally feasible solutions. This enhancement may also be applicable to linear ...
