Última Measuring the Long-Term Regional Benefits of Salinity Reduction 31 Characklis, Gregory W.; Griffin, Ronald C.; Bedient, Philip B.. Approaches for evaluating salinity management benefits are generalized and extended to incorporate consideration of desalination and long-term changes in salinity concentration and water use patterns. Previous research indicates urban users incur the vast majority of salinity-related damages in affected regions, suggesting municipalities may benefit by considering mitigating actions independent of agriculture. However, previous studies have included no consideration of desalination. Earlier studies have also considered stepped increases in salinity, assuming a single future concentration when estimating the long-term benefits of salinity reduction, an approach inconsistent with the incremental nature of these increases. Long-term changes in water use... Tipo: Journal Article Palavras-chave: Benefits; Regional water resource modeling; Salinity; Water quality management; Resource /Energy Economics and Policy. Ano: 2005 URL: http://purl.umn.edu/30779 The Expected Value of Sample Information Analysis for Nonpoint Water Quality Management 31 Sung, Hwansoo; Shortle, James S.. There is considerable interest in watershed-based water quality protection. However, the approach can be highly information intensive, necessitating decisions about the types and amounts of data used to guide decisions. This study examines the Bayesian value of different types and amounts of sample information for reducing nutrient pollution in the Conestoga watershed of Pennsylvania, focusing on nitrogen from agricultural sources. Uncertainty is modeled from the perspective of a social planner seeking to maximize the economic efficiency of water quality control. A nested Monte Carlo procedure combined with an Evolutionary Optimization Strategy with Covariance Matrix Adaptation is used to compute resource allocation that optimizes the expected net benefit...

Ano: 2006 URL: http://purl.umn.edu/21296 The Impact of Water Quality on Southern California Beach Recreation: A Finite Mixture Model Approach 31 Hilger, James; Hanemann, W. Michael. This paper uses a finite mixture logit (FML) model to investigate the heterogeneity of preferences of beach users for water quality at beaches in Southern California. The results are compared with conventional approaches based conditional logit (CL) and random parameters logit (RPL). The FML approach captures variation in preferences by modeling individual recreator choices using a mixture of several distinct preference groups, where group membership is a function of individual characteristic and seasonal variables. The FML parameter estimates are used to calculate welfare measures for improvements in beach quality through a reduction of water pollution. The FML segment specific welfare measures bound the traditional CL and RPL mean welfare estimates, and...
