This article analyses the scope for individual adaptation to flood risk in the South of France. We collected data concerning the implementation of individual adaptation measures and the willingness to pay for individual and collective measures in a survey of 418 respondents living in two flood‐prone areas. First, we observed the current level of adaptation and compared the willingness to pay for individual versus collective measures. We then analysed the drivers of implementation and of willingness to pay. We then provide a cost–benefit analysis of individual adaptation. The survey results show that, despite willingness to pay for reduced risk, few adaptation measures have been implemented. Perceptions of hazards and of damage are important drivers but have different influences: the first favours the implementation of measures; the second increases willingness to pay for measures. Finally, our cost–benefit analysis suggests that completely dry proofing a house up to a height of one metre may not be economically viable. This calls for the promotion of cheaper and more cost‐efficient measures.

法国南部家庭减少水灾风险的意愿

本文分析了法国南部针对洪水风险的个人适应范围。在一项对居住在两个洪灾易发地区的418名受访者的调查中，我们收集了有关实施个体适应措施以及支付个体和集体措施意愿的数据。首先，我们观察了当前的适应水平，并比较了个人和集体措施的支付意愿。然后，我们分析了实施和支付意愿的驱动因素。然后，我们提供了个体适应的成本效益分析。调查结果表明，尽管愿意为降低的风险付出代价，但几乎没有采取适应措施。危害和损害的感知是重要的驱动因素，但会产生不同的影响。第二，增加了支付措施的意愿。最后，我们的成本效益分析表明，对一米高的房屋进行完全干式打样在经济上可能不可行。这就要求推广更便宜，更具成本效益的措施。
