Ad hoc issues of the PPRi COMBEAUTE

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 Risk Prevention Plan (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，风险承险体指受某一灾害威胁、并可能因此遭受影响或破坏的人员、财产、活动、文化或环境遗产要素。某一研究对象对灾害的敏感程度被称为"易损性（vulnerability）"。本对象类别涵盖了风险预防计划（Risk Prevention Plan, RPP）研究中涉及的全部风险点。风险点是具有明确时间节点的对象，其是否纳入考量取决于RPP的制定目标，以及其针对所研究灾害的易损性。因此，RPP风险点是否纳入统计，需根据所针对的灾害类型而定。在开展风险点分析阶段，上述要素构成了在研究区域及其周边制定RPP所需的土地覆被认知基础。本数据集收录的风险点数据，是风险预防计划制定阶段内暴露于各类灾害下的资产与人员的非详尽、示例性快照。该数据集在RPP获批后不再更新，实际应用中亦不再直接复用，而是根据需求结合最新数据源重新计算相关风险点信息。
