We describe the design and implementation of L2W-a problem solving environment (PSE) for landuse change analysis. L2W organizes and unifies the diverse collection of software typically associated with ecosystem models (hydrological, economic, and biological). It provides a web-based interface for potential watershed managers and other users to explore(More)
We present a model of the optimal timing of a large-scale habitat restoration project. The model is a dynamic benefit optimization that includes ecosystem costs caused by the presence of a large dam. We use a single stochastic variable to incorporate two sources of uncertainty: uncertainty about how ecosystem costs will evolve over time and the possibility(More)
In this paper, we estimate the effect of changes in the irrigation water supply on farm employment. In particular, we describe the economic impacts of providing additional in-stream flow for threatened fish species in California's Sacramento-San Joaquin Delta. With water a crucial, but often scarce, resource in California's Central Valley its allocation(More)
