Surface challenge of a PPRT on the department of the Meuse (55)

Generally speaking, the stakes are people, property, activities, cultural or environmental heritage elements, threatened by a hazard and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called “vulnerability”. This object class brings together all the issues that have been addressed in the RPP study. An issue is a dated object whose consideration depends on the purpose of the RPP and its vulnerability to the hazards studied. A PPR issue can therefore be considered (or not) depending on the type or types of hazard being addressed. These elements form the basis of knowledge of the land cover necessary for the development of the RPP, in or near the study area, at the time of the analysis of the issues. The data on issues represent a (figible and non-exhaustive) photograph of assets and individuals exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after approval of the RPP. In practice they are no longer used: the issues are recalculated as necessary with up-to-date data sources.简言之，风险标的（stakes）指受灾害威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一议题对灾害的敏感性被称为易损性（vulnerability）。 本对象类别涵盖了风险预防计划（Risk Prevention Plan, RPP）研究中涉及的全部议题。所谓议题，是一类带有时间属性的对象，其是否被纳入考量取决于RPP的目标，以及其针对所研究灾害的易损性。因此，是否将某一PPR议题纳入评估，需结合所应对的灾害类型而定。 上述要素构成了在议题分析阶段，研究区域及其邻近区域内开展RPP编制所需的土地覆被认知基础。 本议题数据展现了风险预防计划编制阶段，受灾害威胁的各类资产与人员的（虚拟且非穷尽的）快照图景。该数据在RPP获批后不再更新。实际应用中，此类数据已不再被直接使用：相关议题需根据最新数据源按需重新计算生成。
