ABSTRACT

Urban agendas are struggling to challenge conventional planning paradigms, to improve environmental, economic, and social conditions in cities and meet sustainability goals. Such problems call for a critique of existing planning structures, which determine how planners and urban designers work, and thus condition cities themselves. While it is widely acknowledged that descriptive or paradigmatic urban concepts have multiplied in recent years and play a part in shaping development strategies, it is unclear that they reach the desired outcomes. This paper addresses this gap in the case of Portugal, seeking to compare two specific periods of Portuguese planning history: the 1960s and nowadays. For different reasons, both moments urged urban planners and designers to seek urban change. We retrieve key concepts and definitions to call for an observation of how planning at each of those time-periods approached social, political, environmental, and economic challenges. By observing such paradigmatic changes, we aim to identify their advantages and limitations for current urban policies, while gathering eventual lessons for spatial planning to handling the need for a sustainable transition.

摘要

城市议程正在努力挑战传统的规划范式，以改善城市的环境、经济和社会条件并实现可持续发展目标。这些问题需要对现有的规划结构进行批判，这些结构决定了规划者和城市设计师的工作方式，从而影响了城市本身。尽管人们普遍承认，描述性或范式的城市概念近年来成倍增加，并在制定发展战略中发挥了作用，但尚不清楚它们是否达到了预期的结果。本文以葡萄牙为例解决了这一差距，试图比较葡萄牙规划历史的两个特定时期：1960 年代和现在。出于不同的原因，这两个时刻都敦促城市规划师和设计师寻求城市变革。我们检索关键概念和定义，要求观察每个时间段的规划如何应对社会、政治、环境和经济挑战。通过观察这种范式变化，我们旨在确定它们对当前城市政策的优势和局限性，同时为空间规划收集最终的经验教训，以应对可持续转型的需求。
