IndIces of BIotIc IntegrIty In stated Preference ValuatIon of aquatIc ecosystem serVIces

چکیده
Stated preference surveys often give minimal attention to distinctions between intermediate and final ecosystem services, leading to the potential for biased or ambiguous welfare estimates. This paper illustrate ways in which multimetric ecological indexes of the type developed in the ecological literature, here an index of biotic integrity, can be used in stated preference scenarios to both improve the ecological validity of resulting welfare estimates and provide otherwise unavailable information on the value of both intermediate and final ecosystem services. We illustrate the approach using a choice experiment application to the restoration of migratory fish in a Rhode Island watershed.

Using Contingent Valuation to Estimate the Value of Forest Ecosystem Protection
In recent decades, concerns have arisen about the proper valuation of the world's forests. While some of these concerns have to do with market distortions for timber products or inadequate data on non-timber forest products, an additional issue has been the challenge of uncovering the economic worth of non-market services provided by forest ecosystems (Kramer, Healy and Mendelsohn). This has le...
متن کاملValuing Recreational Benefits in an Aquatic Ecosystem Area with Contingent Valuation Method: Case of ShirinSou Wetland, Iran
In this study, the recreational value of ShirinSou Wetland of the Kabodarahang County in Hamadan Province, Iran was estimated and the visitors' willingness to Pay (WTP) was measured by using Contingent Valuation Method (CVM) and One and One Half Bound model (OOHB) dichotomous choice (DC) questionnaire. The results show that 81 percent of investigating individuals will pay for recreational usage...
متن کاملFreshwater Inflow Biotic Index (FIBI) for the Lavaca-Colorado Estuary, Texas
Freshwater inflow is an important source of physical variability in estuaries. Effects of water flow are dynamic, and it is impossible to sample all conditions as they vary over space and time. Benthos, however, are fixed in place, continuously sample the overlying water conditions, and demonstrate a variety of consistent responses to multiple sources of stress. Benthic indices of biotic integr...
متن کاملAssessing the environmental quality status in estuarine and coastal systems: Comparing methodologies and indices
Increasingly on a worldwide scale, legislation has been adopted to determine the ecological integrity of surface waters including streams, rivers, lakes, estuaries and coastal waters. An integral part of determining ecological integrity is the measurement of biological integrity, typically emphasizing analyses of plankton, benthos, macroalgae and fish. In the development of protocols for evalua...

This paper introduces a variant of choice experiment valuation designed to ameliorate common limitations related to a lack of ecological clarity in stated preference survey scenarios. This approach, which we call BioindicatorBased Stated Preference Valuation (BSPV), is distinguished by guidelines that inform the structure and use of ecological indicators to define policy scenarios in valuation ...
