Plans for the prevention of natural hazards (PPRN) 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. The objective of this procedure is to monitor development in areas exposed to a major risk. The PPRNs are decided by the prefects and usually carried out by the departmental directorates of the territories (DDT). These plans regulate land use or use through prohibitions on construction or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The expert information helps to shed light on the expertise conducted within the framework of the PPRN by specifying particular points (fracturing zone, obstacle like a bridge,...) or by adding useful information to the general understanding of the PPRN (e.g. flood markers, flow direction, flow velocity, etc.)自然灾害防治计划（PPRN，英文全称为Plans for the Prevention of Natural Hazards）由1995年2月2日颁布的《加强环境保护法》确立，是国家在风险防控领域的核心管控工具。该类计划的目标是对重大风险暴露区域的开发活动进行监测。 PPRN由省长审定，通常由省领土事务局（DDT，英文全称为Departmental Directorate of Territories）负责执行。此类计划通过禁止建设行为、对现有或拟建建筑提出相关要求（含建设规范、灾害易损性降低工程、农业用地使用或耕作限制等），对土地利用行为进行规制。 此类计划可分为待编制（法定编制阶段）、预实施及已核准三种状态。 专家辅助信息可通过明确特定要点（如断裂带、桥梁等障碍物），或补充有助于全面理解PPRN的相关信息（如洪水标记、水流方向、流速等），来清晰阐释PPRN框架下开展的各项专家论证工作。
