Economic valuation of coastal water quality and protest responses: A case study in Mitilini, Greece
The aim of this study was to evaluate environmental benefits resulting from the construction of a Sewage Treatment Plant (STP) in Mitilini, Greece. The main benefits identified were the improvement of the coastal water quality and subsequent impacts on citizens’ activities. The valuation was conducted using the Contingent Valuation Method (CVM) through the elicitation of individuals’ willingness to pay (WTP). Due to the significant amount of zero and protest responses, different measurements of mean WTP were calculated and the need for further research on social factors which influence individuals’ valuation is emphasized.
