The book concerns and associates two issues of great relevance in the scientific debate on landscape that emerged from the discussion in the thematic sessions of the fourth EUGEO Congress, held in Rome in September 2013. The first question refers to the ability of the landscape to mediate, which is always suspended between performativity and allusion, materiality and symbolic function, knowledge and action; the second regards the need to interpret the landscape not only as a commodity or a public good, but also as a collective resource essential for the well-being of local societies. The essays here proposed address and intersect the two issues moving within diverse and plural theoretical and methodological perspectives
