Much of England’s coastline is underprepared for adapting to long-term coastal change, with many coastal areas moving from ‘hold the line’ to managed realignment as this century progresses. This paper offers a unique case study of a frontage experiencing this transition. It explores the perspectives of Bacton and Walcott residents and coastal policymakers on managing the risk of coastal change for the Bacton-Walcott frontage on the Norfolk coast (UK), after the projected lifetime of a nature-based solution (NBS), known as sandscaping. Drawing upon survey and interview data, this research finds local residents have an increased sense of security of future coastal change through the perceived importance of the nearby Bacton Gas Terminal (currently supplying up to a third of the UK’s gas supply), and the protection afforded to it by sandscaping. For policymakers, sandscaping has bought time to prepare for managed realignment, whereas for residents, sandscaping has bought time to postpone it. There is a risk of maladaptation if reduced concern of future erosion affects willingness to engage in coastal adaptation in the present. This case study highlights the multiple temporal and spatial interests in coastal management, where decision-making at a local level has national-scale implications for domestic energy supply, and where novel nature-based solutions may bring additional uncertainty and complexity to building social resilience. It provides insights on the challenges of anticipatory adaptation, which is of relevance to other coastal areas looking to mitigate climate impacts and better prepare against future risk.

基于自然的变革性解决方案的预期沿海适应面临的挑战


英格兰的大部分海岸线尚未做好适应长期沿海变化的准备，随着本世纪的进展，许多沿海地区从“坚守阵线”转向有管理的重新调整。本文提供了一个关于经历这种转变的临街面的独特案例研究。它探讨了在基于自然的解决方案（NBS）（称为沙美化）的预计使用寿命之后，巴克顿和沃尔科特居民以及沿海政策制定者对管理诺福克海岸（英国）巴克顿-沃尔科特前沿海岸变化风险的看法。 。根据调查和访谈数据，本研究发现，当地居民通过认识到附近的巴克顿天然气终端（目前供应英国多达三分之一的天然气供应）的重要性以及所提供的保护，对未来沿海变化的安全感有所增强通过沙美化来实现它。对于政策制定者来说，沙美化为有管理的调整做好准备赢得了时间，而对于居民来说，沙美化则为推迟调整赢得了时间。如果对未来侵蚀的担忧减少影响了目前参与沿海适应的意愿，则存在适应不良的风险。本案例研究强调了沿海管理中的多重时间和空间利益，其中地方层面的决策对国内能源供应具有全国范围的影响，而基于自然的新颖解决方案可能会给社会复原力建设带来额外的不确定性和复杂性。它提供了有关预期适应挑战的见解，这与其他寻求减轻气候影响并更好地应对未来风险的沿海地区相关。
