“…There are a few studies that employed a valuation scenario that frames marine water falling into passive uses. For example, Bockstael et al (1989) addressed the CVM questions to measure the human values from the Chesapeake Bay. A questionnaire was designed to elicit individuals' attitudes and their maximum willingness to pay for the changes in water quality.…”

The water quality in Ko Chang Marine National Park coast has been problematic for many years. Recently, a conservation plan has been made by the local government for protecting the ocean beaches by constructing a sewage treatment plant in the region. This study uses the contingent valuation method (CVM) to measure the benefits associated with the proposal of the wastewater treatment plant (WWTP), followed by conducting cost-benefit analysis (CBA) in order to justify the feasibility of the public fund appropriation by the government fiscal policy, such as taxes. A completed questionnaire survey of 300 randomly clustered households was analyzed. Household willingness to pay (WTP) was estimated using Tobit models. The results indicate that the mean WTP for the proposed wastewater treatment project is $73.36 per household per year, translating into an aggregate monetary benefit of $298,774 per year for the local community. Additionally, the CBA result shows that the net present value (NPV) of the project attains $465,162.48 per year, internal rate of return (IRR) reaches 9.14 %, and benefit-cost ratio (B/C) ends up with 2.21 with all those intangible benefits excluded from the calculation. Therefore, the proposed wastewater treatment plant project is economically profitable.

“…In total, we collected 51 observations from 9 studies, several of them focusing on particularly relevant sites such as the Chesapeake Bay (Bockstael et al 1989;Feitelson 1992), the Albemarle Lagoon and Pamlico Estuary system (Whitehead et al 2000;Huang et al 1997), and the Peconic Estuary (Johnston et al 2002). et al 2002), to 31.4 million USD/year, which is the estimated value of birdwatching and wildlife viewing in the Peconic estuary (Johnston et al 2002).…”

SummaryThe role of economic analysis in guiding the sustainable development of estuarine and coastal ecosystems is investigated based on a comprehensive review of the literature on the valuation of the recreation, cultural and aesthetic services. The implications of the findings for the sustainable management of coral reefs, Marine Protected Areas, and Small Island Developing States are discussed. Finally, the potential of meta-analytical benefit transfer and scaling up of values at various aggregation levels is demonstrated in the context of coastal tourism and recreation in Europe. The results of the study support the conclusion that the non-material values provided by coastal and estuarine ecosystems in terms of recreational, cultural and aesthetic services represent a substantial component of human well-being. ABSTRACT: The role of economic analysis in guiding the sustainable development of estuarine and coastal ecosystems is investigated based on a comprehensive review

“…There are several approaches to estimate recreational demand changes conditional to environmental quality changes. One approach involves pooling travel cost data to recreational sites with different quality levels (Smith and Desvousges, 1986;Bockstael et al, 1989). The differences in the number of trips taken to different sites are assumed to relate to the site's environmental quality.…”

Terms of use: Documents in Effects of Great Barrier Reef Degradation on Recreational demand: A Contingent Behaviour Approach SummaryDegradation of coral reefs may affect the number of tourists visiting the reef and, consequently, the economic sectors that rely on healthy reefs for their income generation. A Contingent Behaviour approach is used to estimate the effect of reef degradation on demand for recreational dive and snorkel trips, for a case study of the Great Barrier Reef (GBR) in Australia. We assessed how reef degradation affects GBR tourism and to what extent reef-trip demand depends on the visitors' socio-economic characteristics. A count data model is developed, and results indicate that an average visitor would undertake about 60% less reef trips per year given a combined 80%, 30% and 70% decrease in coral cover, coral diversity and fish diversity, respectively. This corresponds to a decrease in tourism expenditure for reef trips to the Great Barrier Reef Marine Park of about A$ 136 million per year.
