The contingent valuation method is one of the most significant approaches of non-market valuation techniques and has been used widely. The authors take it as a tool to analyze the economic benefits of restoring ecosystem service in an impaired river basin, Erhai lake basin. To obtain accurate benefit estimates using CVM technique requires detailed descriptions of the resources being valued. Results from 100 in-person interviews indicate that 84.7% of the households in Erhai lake basin would like to pay for restoring the ecosystem services of Erhai. The analysis of the payment card data shows that the average willingness to pay (WTP) is 80.325 RMB Yuan per household per year. The annual aggregate benefits of restoring ecosystem services of Erhai lake Basin is at least 6.426×107 RMB Yuan,calculated by the number of the households about 800,000 in the Erhai lake basin. This result is a conservative estimate for the economic value of restoring the ecosystem services of Erhai lake basin because of the positive externalities of restoring the ecosystem services on the outside of Erhai lake basin.

Abstract Considering that the economic valuation of ecosystem services is a useful approach to support the conservation of natural areas, we aimed to estimate the monetary value of the benefits provided by a protected area in southeast Brazil, the Serra do Cipó National Park. We calculated the visitor’s willingness to pay to conserve the ecosystems of the protected area using the contingent valuation method. Located in a region under intense anthropogenic pressure, the Serra do Cipó National Park is mostly composed of rupestrian grassland ecosystems, in addition to other Cerrado physiognomies. We conducted a survey consisting of 514 interviews with visitors of the region and found that the mean willingness to pay was R$ 7.16 year–1, which corresponds to a total of approximately R$ 716,000.00 year–1. We detected that per capita income, the household size, the level of interest in environmental issues and the place of origin influenced the likelihood that individuals are willing to contribute to the conservation of the park, as well as the value of the stated willingness to pay. This study conveys the importance of conserving rupestrian grassland and other Cerrado physiognomies to decision makers and society.
