Abstract

Sea level rise (SLR) is among the major climate change effects threating the coasts of the Mediterranean basin, which are increasingly exposed to coastal flooding, especially along the low lying coastal plains, river deltas, lagoons and reclamation areas. Coastal erosion, beach retreat and marine flooding are already causing unprecedented environmental and socio-economic impacts on coastal populations. According to the Intergovernmental Panel on Climate Change (IPCC) these effects are expected to worsen by 2100 and beyond with a projected global SLR up to about 1 m above the current level. This study provides an overview of the Mediterranean basin, focusing on the vulnerable city of Venice, which is particularly exposed to marine flooding due to SLR and land subsidence. We show the current and future sea level trend as well as a flooding scenarios in the absence of the Experimental Electromechanical Module (MoSE), which is protecting the city of Venice since 2020. To understand the awareness of citizens in Venice to address SLR, we have engaged a group of stakeholders through a structured participatory process to develop solution-oriented, case-specific and site-specific Policy Tools. Our results show that the Policy Tools contain relevant, effective and implementable actions stemming from stakeholder interaction and consensus building, identifying relevant issues that should be considered for SLR adaptation policies. A more extensive participation in public processes is required to materialize the Policy Tools into concrete actions to help vulnerable areas adapt to the expected SLR by the end of this century.

地中海沿岸的海平面上升和极端事件:威尼斯的案例以及当地居民、利益攸关方和决策者的认识
海平面上升(SLR)是威胁地中海盆地沿海地区的主要气候变化影响之一,这些地区,特别是沿低洼的沿海平原、河流三角洲、泻湖和填海地区,越来越多地受到沿海洪水的威胁。海岸侵蚀、海滩后退和海洋洪水已经对沿海居民造成了前所未有的环境和社会经济影响。根据政府间气候变化专门委员会 (IPCC) 的预测,到 2100 年及以后,这些影响将进一步加剧,预计全球可持续土地覆 盖率将比目前高出约 1 米。本研究概述了地中海盆地的情况,重点关注脆弱的威尼斯市,该市尤其容易受到可持续土地上升和地面沉降造成的海洋洪水的影响。我们展示了当前和未来的海平面趋势,以及在没有实验机电模块(MoSE)的情况下的洪水情景。为了了解威尼斯市民对解决可持续土地退化和干旱问题的认识,我们通过结构化的参与式流程,让一批利益相关者参与进来,开发以解决方案为导向、针对具体案例和具体地点的 "政策工具"。我们的结果表明,这些政策工具包含了相关的、有效的和可实施的行动,这些行动源于利益相关者的互动和共识的建立,确定了可持续土地退化和干旱适应政策应考虑的相关问题。需要更广泛地参与公共进程,才能将政策工具落实为具体行动,帮助脆弱地区在本世纪末适应预期的可持续土地退化。
