Valuing the benefits of an urban park project: A contingent valuation study in Thessaloniki, Greece

This paper aims to estimate the non-market benefits derived from the potential development of a new urban park in the city of Thessaloniki (Greece). The city of Thessaloniki has up to now a very low rate of proportional green space per capita. On this context a large metropolitan park was announced, as part of a large-scale redevelopment project, but the final decision has not been made yet. In order to help policy makers to their final decision, an ex-ante valuation of the potential benefits of the park is carried out in this study. A contingent valuation survey was designed and implemented aiming to estimate the willingness to pay of local residents for the provision of this park, as well as to determine the spatial scale at which these values are assessed. The main finding of this study is that people living within 20 min from the reference site are willing to contribute a significant amount of money to support this project. Another interesting outcome is that the willingness to pay for this project was not considerably modified during a period of economic recession (2010-2013), which is mainly due to the growing public awareness of the importance of green spaces, as well as of the benefits of the planned park.
