Urban sustainability and knowledge: Theoretical heterogeneity and the need of a transdisciplinary framework. A tale of four towns

摘要

The academic debate on (sustainable city» is like a large arena, where heterogeneous approaches and contributions, coming from different disciplines, flow into without converging on a common vision. The growing awareness that an increasing percentage of the world's population now lives in urban areas makes the organization of this space a crucial issue for global sustainable development. In order to acquire this challenge, urban studies need to overcome conceptual oppositions, seeking new integrated responses to implement the principle of sustainability at urban scale. This effort requires a new managerial approach of science and policy, which can be based on a transdisciplinary vision to knowledge production. The paper is divided into four different sections. The first and second sections review the theoretical literature on urban sustainability and explore the conceptual relations between knowledge and knowledge production in urban governance processes. The third section presents a comparative empirical analysis based on a survey of 2213 questionnaires carried out in four different urban contexts. The fourth and last section outlines the conclusion, suggesting a new approach to manage knowledge in urban governance, in a trans-disciplinary perspective.
