The Forest Fire Advanced System Technology (FFAST) project is developing a data system to provide near-real-time forest fire information to fire management at the fire Incident Command Post (ICP). The completed conceptual design defined an integrated forest fire detection and mapping system that is based upon technology available in the 1990's. System component technologies identified for an en...

Impact of changes in land cover and land use on hydrological service of tropical watersheds is one of the focal research tropics in both hydrology and Land Cover Land Use Changes (LCLUC). Land fragmentation is an important feature of LCLUC, however, its impact on hydrological service of tropical watershed is unclear despite a few theoretical frameworks. In this paper, we described a simulation ...
The Forest Service, the largest agency in the U.S. Department of Agriculture, has traditionally used the expression "community stability" to describe its rural development policy. That has meant growing and harvesting trees following principles of "sustained yield" so that local industries (and the employment they generate) can be supported over long periods of time. In recent years, however, e...
