Assessing the Preservation of Parks and Natural Protected Areas: A Review of Contingent Valuation Studies

The existence of parks is particularly important and offers many benefits both to the environment and to humans. Parks are recreational spaces, which contribute to the improvement of the microclimate, reduce atmospheric pollution and protect biodiversity. Their importance for the urban environment is even greater because they offer pure oxygen to the city and people feel close to nature in them. The aim of this study is to review studies which took place globally as well as in Greece, relying on the Contingent Valuation Method (CVM) for parks. The reason that this method is used is the valuation of non-market goods and services through the development of a hypothetical market. Additionally, a distinction is made among previous empirical studies depending on the nature of the parks and the country where the survey was conducted, while the disadvantages that must be considered from the use of Contingent Valuation Method are mentioned. According to the findings of the literature review, studies using Contingent Valuation in Greece, particularly in the case of urban parks, are limited. As far as we know, the valuation of existing urban parks has not yet been studied, so this could be a field for further research. The economic valuation of parks in a country like Greece, which suffered with the financial crisis, can lead to conclusions about the value that citizens attribute to parks and the identification of possible protest responses.
