Abstract

Nature based coastal adaptation (NbCA) sustainably helps minimize sea-level rise impacts, using and enhancing the natural capacity of coastal ecosystems. Despite its relative advantages over conventional hard protection infrastructure, the implementation of NbCA is challenged by diverse barriers, many of which cannot be overcome in the absence of appropriate policy directives. This paper draws on organizational practitioners’ case study narratives collected from six NbCA projects planned and/or implemented in Nova Scotia, Canada, to answer how the implementation of NbCA approaches can be navigated through adoption barriers. Results reveal that institutional and psychological barriers dominate, and they also show path-dependency. In addition, barriers are often influenced by the biophysical properties of a restoration site. To navigate through barriers, it is important to identify policy opportunities and redistribute roles and responsibilities. Organizational knowledge creation through partnership and community engagement are two other strategies required for the successful implementation of NbCA.

摘要

基于自然的海岸适应 (NbCA) 可持续地帮助最大限度地减少海平面上升的影响，利用和增强沿海生态系统的自然容量。尽管 NbCA 相对于传统的硬保护基础设施具有相对优势，但其实施仍面临各种障碍，如果没有适当的政策指令，其中许多障碍是无法克服的。本文借鉴了从加拿大新斯科舍省计划和/或实施的六个 NbCA 项目中收集的组织从业者的案例研究叙述，以回答如何通过采用障碍来引导 NbCA 方法的实施。结果表明，制度和心理障碍占主导地位，它们也表现出路径依赖性。此外，障碍物通常受到修复地点的生物物理特性的影响。为了克服障碍，重要的是要确定政策机会并重新分配角色和责任。通过伙伴关系和社区参与创造组织知识是成功实施 NbCA 所需的另外两项战略。
