How to manage the Value of Drinking water by using Extension on the Contingent Valuation Method

This paper examines an explanatory policy in the management of drinking water in Tunisia. Indeed, the price variable, while is considered, in general way, as a confident indicator in the regulation of drinking water consumption, it seems to be insufficient since the management of drinking water is influenced by other set of variables such as: the revenue level of households, the consumption of bottled water, the alternative sources, the household size and, above all, the quality variable, which presents an enormous variability inter- and intra-regions. Through our study, we have shown, that the variation in willingness to pay (WTP) is essentially due to psychological and subjective consideration (the degree of importance of these variables in the scale of preferences of consumers).

Valor económico de la conservación de la biodiversidad: el caso del Parque Nacional Yanachaga-Chemillén

The present study determined the willingness to pay for the conservation of the biodiversity (WTP) of the Yanachaga-Chemillén National Park (YChNP), applying the contingent valuation method, in hypothetical scenarios of conserving 6, 9 or 12 species that guaranteed protection of 50 % of the functionality of the ecosystems of this place. It was found that the WTP was determined by the functional characteristics that key species play in the resilience of the PNYCh ecosystems. For this reason, similar studies should evaluate the option of preferring the use of functionality instead of indicators based, for example, on the number of species.

Visitor’s Willingness to Pay for National Park Entrance Fees in China: Evidence from a Contingent Valuation Method

China has been making efforts in nature conservation by developing a new national park system. Setting a fee-based entrance policy for the newly established national parks can be challenging without information on visitors’ willingness to pay (WTP). Thus, this study aims to evaluate visitors’ WTP entrance fees with a dataset of 1215 visitors collected in China’s planned Qinling National Park (QNP). Using the double bounded dichotomous choice format of the contingent valuation method, we obtained the mean WTP for the entrance fee of QNP of 200 yuan. Visitors’ demand becomes relatively inelastic at the recommended entrance fee of 160 yuan when the expected ticket revenue will reach its maximum of 13.8 billion yuan. Our study also indicates that visitors’ WTP is significantly influenced by their gender difference, education level, income, number of trips to natural attractions, duration of stay, the intention of a future visit, and concern about commercial exploitation. Our empirical study provides insights into developing effective pricing policies and appropriate marketing strategies for China’s new national park system.

The Interrelationship of Sustainable Economic Value of Watersheds Using Contingent Valuation Method Approach with Circular Economy: A Literature Study

Waste accumulation mainly causes environmental damage. Watersheds experience high waste pollution problems. Therefore, the need to maintain ecological sustainability by maintaining the cleanliness of the watershed environment. This research studies the interrelationship of economic value in watersheds as measured by the contingent valuation method approach with the circular economy. This research aims to identify the application of circular economy and know the use of the contingent valuation method approach in measuring the economic value of natural resources in the form of watersheds. The method used is a descriptive approach using literature studies. This research uses secondary data by collecting data and information through website-based electronic media, relevant journals, previous research, and so on. The results of this research are measuring the economic value of watersheds using circular economy and using the contingent valuation method to find out how willing to pay from the community towards environmental improvement and the desire to receive compensation from ecological damage. The application of a circular economy is expected to reduce waste pollution and can increase economic growth.
