Facilitating the decline of unsustainable urban infrastructure

有两种过程将可持续的社会技术实践纳入主流：支持采用替代品的过程（已经进行了大量研究），以及促进被取代的实践衰落的过程（迄今为止被严重忽视）。暴露硬币的第二个和不太明显的一面，这项研究的目的是开发一个更全面和平衡的理论，比目前的城市基础设施变化的基础帐户，并深入了解“界面”之间的抛弃旧的和采用新的。为了补充理论，它旨在提供第一个削弱旧范式的过程的实证研究。预计成果将包括一个新的研究议程和一个实践者工具包，以解决可持续性过渡的体制障碍。

Two kinds of process bring sustainable socio-technical practices into the mainstream: those supporting adoption of alternatives (much studied already), and those facilitating decline of superseded practices (seriously neglected so far). Exposing that second and less visible side of the coin, this research aims to develop a more holistic and balanced theory than current advocacy-based accounts of urban infrastructure change, and insights into the 'interface' between discarding the old and adopting the new. To complement theory, it aims to offer the first empirical study of processes that weaken old paradigms. Outcomes are expected to include a new research agenda and a practitioner toolkit for addressing institutional barriers to sustainability transitions.
