Both Venice and Miami are high-density coastal cities that are extremely vulnerable to rising sea levels and climate change. Aside from their sea-level location, they are both characterized by large populations, valuable infrastructure and real estate, and economic dependence on tourism, as well as the availability of advanced scientific data and technological expertize. Yet their responses have been quite different. We examine the biophysical environments of the two cities, as well as their socio-economic features, administrative arrangements vulnerabilities, and responses to sea level rise and flooding. Our study uses a qualitative approach to illustrate how adaptation policies have emerged in these two coastal cities. Based on this information, we critically compare the different adaptive responses of Venice and Miami and suggest what each city may learn from the other, as well as offer lessons for other vulnerable coastal cities. In the two cases presented here it would seem that adaptation to SLR has not yet led to a reformulation of the problem or a structural transformation of the relevant institutions. Decision-makers must address the complex issue of rising seas with a combination of scientific knowledge, socio-economic expertize, and good governance. In this regard, the “hi-tech” approach of Venice has generated problems of its own (as did the flood control projects in South Florida over half a century ago), while the increasing public mobilization in Miami appears more promising. The importance of continued long-term adaptation measures is essential in both cities.

威尼斯和迈阿密对海平面上升的适应是否为其他脆弱的沿海城市提供了教训？

威尼斯和迈阿密都是高密度的沿海城市，极易受到海平面上升和气候变化的影响。除了海平面位置外，它们的特点是人口众多、基础设施和房地产价值高、经济依赖旅游业，以及先进科学数据和技术专长的可用性。然而，他们的反应却截然不同。我们研究了这两个城市的生物物理环境，以及它们的社会经济特征、行政安排的脆弱性以及对海平面上升和洪水的反应。我们的研究使用定性方法来说明适应政策是如何在这两个沿海城市出现的。根据这些信息，我们批判性地比较了威尼斯和迈阿密的不同适应性反应，并建议每个城市可以相互学习什么，并为其他脆弱的沿海城市提供经验教训。在此处介绍的两个案例中，似乎对 SLR 的适应尚未导致问题的重新制定或相关机构的结构转型。决策者必须结合科学知识、社会经济专业知识和良好治理来解决海平面上升这一复杂问题。在这方面，威尼斯的“高科技”方法本身就产生了问题（就像半个多世纪前南佛罗里达的防洪项目一样），而迈阿密日益增加的公众动员似乎更有希望。持续的长期适应措施对这两个城市都至关重要。
