Multi-scale integrated analysis of societal and ecosystem metabolism (MuSIASEM): Theoretical concepts and basic rationale

Giampietro, Mario; Mayumi, Kozo; Ramos-Martin, Jesus - In: Energy 34 (2009) 3, pp. 313-322

scales. Since sustainability deals with “becoming systems”—systems becoming something else in their process of evolution …—an analysis of sustainability must adopt analytical tools semantically open in their representation of change. MuSIASEM can do … “becoming” when studying sustainability. That is, it entails an agreement on an expected set of relations between “relevant …
