Abstract There is increasing global concern that climate adaptation efforts are falling behind the increasing risks associated with climate change. A number of reviews have identified this general issue in multiple nations and jurisdictions. In Australia, it is argued here that adaptation of the coastal built environment is operating at two speeds: the two-speed adaptation economy. Large civil assets and facilities in Australia now mostly have adaptation plans and strategies in place; although progress in actual on-the-ground implementation is variable in some cases. By contrast, adaptation of coastal communities and settlements continues at a very slow pace with very few specific adaptation measures being implemented that were not already being implemented as business as usual for flood or erosion management. The reasons for these differences in adaptation progress is investigated here. A key outcome of the thinking presented here is the reinforcement of the result that adaptation of coastal communities is not a challenge of relocating buildings, but rather a challenge of incentivising and supporting communities to act.

澳大利亚的两速沿海气候适应经济

摘要 全球越来越关注气候适应努力落后于与气候变化相关的日益增加的风险。许多审查已在多个国家和司法管辖区确定了这一普遍问题。在澳大利亚，这里有人认为沿海建筑环境的适应以两种速度运行：两种速度适应经济。澳大利亚的大型民用资产和设施现在大多制定了适应计划和战略；尽管在某些情况下实际实地实施的进展是可变的。相比之下，沿海社区和定居点的适应继续以非常缓慢的速度进行，正在实施的具体适应措施很少，而且还没有像往常一样实施洪水或侵蚀管理。此处调查了适应过程中这些差异的原因。这里提出的思想的一个关键结果是强化了这样的结果，即沿海社区的适应不是搬迁建筑物的挑战，而是激励和支持社区采取行动的挑战。
