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，承灾体是指受灾害（hazard）威胁、并可能因该灾害遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象针对灾害的敏感性被称为"易损性（vulnerability）"。 本对象类别涵盖了风险防控计划（Risk Prevention Plan，以下简称RPP）研究中涉及的全部研究对象。研究对象是一类带有时间标记的实体，其是否被纳入考量取决于RPP的研究目标，以及其针对所研究灾害的易损性。因此，是否将某一RPP研究对象纳入分析，需根据所针对的灾害类型而定。 在开展研究对象分析阶段，上述要素构成了研究区域及其周边区域内RPP编制所需的土地覆被认知基础。 研究对象相关数据，是风险防控计划编制阶段受灾害威胁的资产与人群的具象化且非穷尽式现状快照。该数据在RPP获批后不再更新。实际应用中该数据亦不再直接使用，而是根据需求依托最新数据源重新计算得到研究对象相关信息。
