海岸线装甲涉及安装硬化结构以保护沿海财产,它极大地改变了海岸线的组成和由此产生的生态功能。日益增长的沿海社区面临的危险威胁加剧,使这个问题更加复杂化,从而产生了对更多装甲的需求。我们研究了美国沿海屏障资源法案(CBRA)(该法案旨在抑制危险沿海屏障上的城市开发)的指定是否与保护海岸线的较低倾向相关。在指定地区,CBRA 取消了获得联邦补贴的洪水保险、基础设施补贴和灾害援助的机会。我们使用逻辑回归模型,在控制 CBRA 指定、土地使用和当地人口密度的情况下,以地块规模检查整个佛罗里达州(美国)的装甲情况。我们的研究结果表明,CBRA 指定与装甲几率之间存在显着的负相关关系,特别是对于住宅和空置房产。随着沿海地区努力应对沿海灾害日益严重的影响,取消公共补贴可能是维持自然海岸线生态和保护效益的有效非监管方法。
Shoreline armoring, which involves the installation of hardened structures to protect coastal property, dramatically alters shoreline composition and resulting ecological functions. Accelerating hazard threats to growing coastal communities compounds this problem, creating demand for more armoring. We examine whether designation by the U.S. Coastal Barrier Resources Act (CBRA) – enacted to disincentivize urban development on hazardous coastal barriers – is associated with lower propensities to armor shorelines. In designated areas, CBRA removes access to federally-subsidized flood insurance, infrastructure subsidies, and disaster assistance. Using logistic regression modeling, we examine armoring at the parcel scale across the State of Florida (USA), controlling for CBRA designation, land use, and local population density. Our findings reveal a significant negative relationship between CBRA designation and the odds of armoring, particularly for residential and vacant properties. As coastal areas grapple with increasing impacts from coastal hazards, removal of public subsidies may be an effective non-regulatory method for maintaining the ecological and protective benefits of natural shorelines.
