The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention.
Their objective is to monitor development in areas exposed to a major risk.
The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT).

风险预防计划（Risk Prevention Plans，PPR）由《1995年2月2日加强环境保护法案》确立，系该国风险预防领域的核心政策工具。其目标为对存在重大风险的区域内的开发活动进行监测管控。此类计划由省长审批，通常由领土事务部门主管局（DDT）负责执行。该类计划通过对现有或未来建筑设置建设禁令或提出相关要求（涵盖建设规范、降低脆弱性工程、使用或作业限制等），规范土地利用或调整土地用途（如农业相关用途等）。本次数据集为采用COVADIS格式编制的萨特河上游自然洪水风险预防计划监管分区方案，该分区已于2007年6月20日通过省长令获批。
