In light of increasing losses from floods, many researchers and policymakers are looking for ways to encourage flood risk reduction among communities, business, and households. In this study, we investigate risk-reduction behavior at the household level in three European Union Member States with fundamentally different insurance and compensation schemes. We try to understand if and how insurance and public assistance influence private risk-reduction behavior. Data were collected using a telephone survey (n = 1,849) of household decisionmakers in flood-prone areas. We show that insurance overall is positively associated with private risk-reduction behavior. Warranties, premium discounts, and information provision with respect to risk reduction may be an explanation for this positive relationship in the case of structural measures. Public incentives for risk-reduction measures by means of financial and in-kind support, and particularly through the provision of information, are also associated with enhancing risk reduction. In this study, public compensation is not negatively associated with private risk-reduction behavior. This does not disprove such a relationship, but the negative effect may be mitigated by factors related to respondents' capacity to implement measures or social norms that were not included in the analysis. The data suggest that large-scale flood protection infrastructure creates a sense of security that is associated with a lower level of preparedness. Across the board there is ample room to improve both public and private policies to provide effective incentives for household-level risk reduction.
鉴于洪水造成的损失不断增加,许多研究人员和政策制定者正在寻找鼓励社区、企业和家庭降低洪水风险的方法。在这项研究中,我们调查了三个欧盟成员国的家庭层面的风险降低行为,这三个成员国的保险和补偿计划有根本的不同。我们试图了解保险和公共援助是否以及如何影响私人风险降低行为。数据是通过对洪水多发地区的家庭决策者进行电话调查(n=1849)收集的。我们表明,保险总体上与私人风险降低行为呈正相关。在结构措施的情况下,保险的这种积极关系可能归因于对风险降低的保证、保费折扣和信息提供。通过财政和实物支持以及特别是通过提供信息来鼓励风险降低措施的公共激励措施也与增强风险降低有关。在这项研究中,公共补偿与私人风险降低行为没有负相关。这并没有否定这种关系,但由于与受访者实施措施的能力或未包括在分析中的社会规范相关的因素,这种负效应可能会减轻。数据表明,大规模的洪水保护基础设施创造了一种安全感,这与较低的准备水平有关。在各个方面,都有充分的空间来改善公共和私人政策,为家庭层面的风险降低提供有效的激励措施。
