Urban areas are hot spots of flood risk due to how urban development concentrates people and assets into hazard prone areas, reinforcing negative externalities on the welfare of urban residents. Mitigating flood risk in urban environments, however, is challenging. This is not only because the process generating flood risk is complex, but the objectives of city planners, residents and/or developers are also multi-faceted. Therefore, there are various trade-offs to be considered. One such problem across many areas of Europe and beyond is how to regenerate declined urban areas, to improve the welfare, prosperity, and image of the city. However, in turn, many areas within these cities will see this activity being traded-off against increased flood risk. Cost-benefit analysis represents a useful approach for assessing this trade-off, as a decision-support tool. In this paper we present an exploratory cost-benefit analysis of a potential urban regeneration project within the city of Ústí nad Labem (Czechia) that seeks to highlight the potential magnitude of such trade-offs that need to be more often actively considered as a core, rather than peripheral, element of urban regeneration. We present an exploratory framework that can be expanded upon and integrated into wider regeneration visions.

平衡城市更新和洪水风险管理之间的相互作用——Ústí nad Labem 的成本效益方法

城市地区是洪水风险的热点地区,因为城市发展如何将人员和资产集中到易受灾地区,从而加剧了城市居民福利的负面外部性。然而,减轻城市环境中的洪水风险具有挑战性。这不仅是因为产生洪水风险的过程很复杂,而且城市规划者、居民和/或开发商的目标也是多方面的。因此,需要考虑各种权衡。欧洲及其他地区许多地区面临的一个此类问题是如何重建衰落的城市地区,以改善城市的福利、繁荣和形象。然而,反过来,这些城市内的许多地区将看到这项活动正在与增加的洪水风险进行权衡。成本效益分析是评估这种权衡的有用方法,作为决策支持工具。在本文中,我们对 Ústí nad Labem(捷克)内的潜在城市更新项目进行了探索性成本效益分析,旨在强调需要更积极地将其视为核心的此类权衡的潜在规模,而不是外围的城市更新元素。我们提出了一个探索性框架,可以扩展并整合到更广泛的再生愿景中。
