In this Special Issue, we collected manuscripts focusing on sustainability; study cases and opinion papers about initiatives, definitions, policies, programs, and ideas; traditional knowledge and new applications; criticism and new proposals; natural resource uses, conflicts, and growth problems; and issues related to global change (changes in, for example, climate, uses, needs, soil occupation, society, public opinion, species composition, and ecosystems). These manuscripts have a particular focus on landscape, water, ground, and societal characteristics in global change scenarios.
