Advancing urban sustainability theory and action: Challenges and opportunities

摘要: a b s t r c Urban ecology and its theories are increasingly poised to contribute urban sustainability, through both basic understanding action. We present conceptual framework that expands the Indus- trial → Sanitary Sustainable City transition include non-sanitary cities, "new cities", various permutations of options for cities encountering exogenous endogenous "triggers change". When investigating modeling these transitions, we should consider: (1) triggers have induced change; (2) situations where crisis (3) why toward more sustainable states on their own, in absence crisis; (4) what can learn from new city transitions; (5) how resource interactions affect s. Several existing theoretical frameworks, including resilience, adaptation, vulnera- bility, may be helpful when considering transitions. suggest all interact inertia systems, this multi-faceted inertia—e.g. institutional inertia, infras- tructural social inertia—imparts degrees rigidity make systems less flexible nimble facing transitional change. Given this, solutions sustainability challenges categorized as those: "tweak" current work with or even take advantage those versus; "transformative", confront systemic require systems. propose model addressing context relevant theory, bridging research practice, focus intercity comparisons.
