How do environmental knowledge, environmental sensitivity, and place attachment affect environmentally responsible behavior? An integrated approach for sustainable island tourism

Previous studies have explored tourists' environmentally responsible behavior (ERB) from the perspectives of individual commitment, attractiveness, and involvement. This study approaches from the standpoint of environmental knowledge (EK); it probes tourists' behavior to facilitate sustainable tourism development, and constructs a sustainable island tourism development model by integrating EK, environmental sensitivity, place attachment, and ERB. Four hundred and seventy seven tourists visiting the Penghu Islands, Taiwan, were surveyed. Structural equation modeling was used to determine the relationships among the variables and the mediating effects. Results indicate that higher levels of tourists' EK about the Penghu Islands are associated with stronger environmental sensitivity; environmental sensitivity which tourists have for island tourism is positively associated with place attachment. The extent of place attachment of Penghu as perceived by tourists is also positively associated with stronger ERB. When tourists are highly sensitive to the attraction, they are more likely to exhibit ERB. Environmental sensitivity and place attachment were found to exert significant effects in mediating the relationships between EK and ERB. This study pioneers the integration of all four constructs in a sustainable tourism behavior model for tourists to island tourism destinations. Suggestions for marketing and implementation of sustainable tourism, and their managerial implications are proposed.
