Urban resilience and urban sustainability: What we know and what do not know?

摘要

AbstractThe past literatures have studied both ‘urban resilience (UR)’ and ‘urban sustainability (US)’ in terms of the dual character - vulnerability and pertinacity - of cities. However, there is a large overlap between the meaning of resilience and sustainability, which threatens to weaken both concepts. In this study, we discuss the difference between urban resilience (UR) and urban sustainability (US) from three aspects of research trends, research scale and research clusters. CiteSpace 4.0.R5 is used for co-citation analysis, visualizing co-citation networks and research clusters. UR and US studies contrast in not only their different theoretical bases, but also even more in their empirical work. A conceptual framework is proposed to define the difference between UR and US, and four kinds of urban development are examined based on the framework. We indicate that rational urban development can be achieved only when it is both resilient and sustainable, and conclude that urban planners, policymakers and researchers should pay equal attention to both UR and US before decision-making.Highlights•The difference between urban resilience (UR) and urban sustainability (US) are discussed.•The Sea Gate project of New York harbor is used as a case study to demonstrate that UR and US can be contradictory.•A conceptual framework is proposed to define the difference between UR and US.•Four kinds of urban development are examined based on the framework.•Rational urban development can be achieved only when it is both resilient and sustainable.
