“…In environmental economics, the conventional approach for conducting stated preferences (SP) studies for valuing landscape has been to design a survey, select a set of attributes, describe their changes, mostly through qualitative levels (for example, 'low, medium, high' or 'no action, some action, a lot of action'), often using percentage changes, and simplified graphical representations of the landscape, and elicit respondents' preferences for these attributes (Campbell, 2007;Colombo et al, 2015;Domínguez-Torreiro and Soliño, 2011;Giergiczny et al, 2015;Hanley et al, 2007;Newell and Swallow, 2013;Rambonilaza and Dachary-Bernard, 2007).…”
