Over the last decades, interim reuse has emerged as a possible solution for vacant land and abandoned spaces in cities. It is presented as an alternative to conventional regeneration projects, opening up new possibilities for the occupation of formerly derelict spaces. However, in addition to such opportunities, it also poses a number of risks which need to be mitigated, calling for new mechanisms that foster the consultation and participation of communities within the scope of urban planning. The present research seeks to fill this gap by introducing scenario-elicitation, an innovative participation methodology, which relies on new visualisation and communication techniques in planning. Application of the methodology to an abandoned industrial lot in Barreiro – a shrinking city in the suburban belt of Lisbon, Portugal – yielded the following conclusions: (i) scenario-elicitation constitutes a potential tool for the consultation of communities, as a complement to other visualisation and communication techniques in planning; (ii) interim reuse is embraced by communities as a useful device to respond to vacancy and urban abandonment situations; (iii) citizens' adherence to types of interim reuse is geared, primarily, towards collective space options linked to healthy living practices and the combination of different functional and spatial assets.

在过去的几十年中，临时复用已成为解决城市中空置土地和废弃空间的一种可能解决方案。它是传统再生项目的替代方案，为占领以前废弃的空间开辟了新的可能性。但是，除了这些机会之外，它还带来了许多需要减轻的风险，需要建立新的机制来促进城市规划范围内社区的协商和参与。本研究试图通过引入情景启发法来填补这一空白，这是一种创新的参与方法，它依赖于规划中新的可视化和交流技术。该方法在Barreiro的废弃工业地段中的应用-Barreiro是里斯本郊区的一个不断萎缩的城市，葡萄牙–得出以下结论：（i）情景设想是进行社区协商的一种潜在工具，作为规划中其他可视化和交流技术的补充；（ii）社区将临时复用作为应对空缺和城市遗弃情况的有用手段；（iii）公民对临时再利用类型的遵守主要是针对与健康的生活习惯相关联的集体空间选择，以及不同功能和空间资产的组合。
