Sustainability Assessment: The Role of Entropy‐Based Indicators for Reconnecting Human' Subjectivity and Civilization With Natural Tendency of Ecosystems

Sustainable Development, EarlyView.
ABSTRACT Sustainability represents a complex issue in which scientific knowledge inevitably coexists with the subjective perception of humans in its turn influenced by civilization, cultural but also unconscious aspects. These results emerge with evidence from a critical analysis of the main definitions of sustainability delivered by credited entities (
