This document is a preliminary effort to draw together some of the important simulation models that are available to Reclamation or that have been developed by Reclamation since 1987. This document has also attempted to lay out a framework by which these models might be used both for the...

"Ecological problem solving requires a flexible social infrastructure that can incorporate scientific insights and adapt to changing conditions. As applied to watershed management, social infrastructure includes mechanisms to design, carry out, evaluate, and modify plans for resource protection...

From Introduction:"The abatement of Nile pollution is a serious concern in Egypt's development. Four factors support this assertion, (i) demand for water exceeds available freshwater; (ii) water demand is increasing over time; (iii) opportunities to increase the water supply are limited; and (iv)...

Die Dissertation mit dem Titel “Battle and Beating, Water and Waste: Micro-Level Impact Evaluation in Developing and Emerging Economies” beinhaltet die Ergebnisse ökonometrischer Wirkungsevaluierungen, die innerhalb zwei verschiedener Themengebieten des täglichen Lebens in Entwicklungs-...

The impact of livestock grazing on water quality, especially erosion and sedimentation, is an important concern in the southwestern United States. In response to Federal and State regulations, Best Management Practices (BMPs) for rangeland management are being developed and implemented in many...

We investigate second-best, input-based taxes foragricultural nonpoint pollution control when marketprices are endogenous and production isheterogeneous. Theoretically, we derive the optimalforms of taxes which take account of heterogeneity(non-uniform taxes) and a tax which does not (auniform...

Feed represents the largest cost input in intensive catfish Ictalurus punctatus production. Daily feed rations are generally related to stocking densities, up to a point at which high feeding rates begin to affect water quality. There has been no prior research to analyze the economic...

Water quality trading between point and nonpoint sources is of great interest as an alternative to strict command and control regulations on point sources for achieving water quality goals. The expectation is that trading will reduce the costs of water quality protection, and may speed...
