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.一般而言，承灾体（stakes）指受灾害威胁、并可能因此遭受影响或损毁的人员、资产、活动、文化或环境遗产要素。某一对象对灾害的敏感程度被称为脆弱性（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。议题（issue）为带有时间标记的对象，其考量需结合风险预防计划的目标以及其针对所研究灾害的脆弱性。因此，某一PPR议题是否被纳入考量，取决于当前应对的灾害类型。 在议题分析阶段，上述要素构成了在研究区域内或其周边编制风险预防计划所需的土地覆被认知基础。 议题相关数据呈现了风险预防计划编制阶段，受灾害威胁的资产与人员的（形象化且非穷尽的）快照。该数据在风险预防计划获批后不再更新。实际应用中此类数据已不再直接使用，相关议题将根据需要采用最新数据源重新计算生成。
