Natural risk prevention plan for field movement — Commune de Montaigu-de-Quercy — Types of risk treated in a multi-risk PPRN — Department of Tarn-et-Garonne

Non-geometric table to be used for multi-hazard RPPs to inform the types of risk addressed in the RPP.

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. Their objective is to monitor development in areas exposed to a major risk.
The PPRNs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through building prohibitions 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 PPRN file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPRN is identified by a polygon that corresponds to the set of affected municipalities within the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table allows to map existing PPRNs on the department.
Each PPRN document in this geographical table is linked with its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and serial number of the associated PPRN procedure in GASPAR):
1. its administrative procedure for drawing up (or revising) managed in the GASPAR application, on the one hand,
2. its set of constituent geographic data described in the metadata sheet N_PPRN_AAAANNNN, on the other hand.

本非地理数据表适用于多灾害风险预防计划（multi-hazard Risk Prevention Plans, RPPs），用以明确该类计划所覆盖的风险类型。
自然灾害预防计划（Plans for the prevention of natural hazards, PPRN）由1995年2月2日《加强环境保护法案》确立，是国家在风险预防领域的核心管控工具，其目标是对重大风险暴露区域的开发活动实施监测。
PPRN由省长批准，通常由省级领土总局（DDT）负责落地执行。此类计划通过对现有及未来建筑设定建筑禁令或提出建设要求（包括建设规范、减灾工程、农业用途限制或耕作行为约束等），规范土地利用与开发活动。
PPRN可分为三种状态：待编制（核定）、提前实施及已获批。
PPRN档案包含说明性纪要、管制分区图及管制条例，此外可附加有助于理解该计划的其他图文资料（如灾害分布、核心问题等）。每个PPRN通过多边形标识：当计划处于核定状态时，该多边形对应法定范围内受影响的市镇集合；当计划处于获批状态时，则对应管制区域的外包范围。本地理数据表可用于绘制省内现有PPRN的空间分布图。
本地理数据表中的每份PPRN文档均关联有格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"的GASPAR代码（其中AAAA与NNNN分别对应GASPAR系统中相关PPRN流程的基准年份与序列号）：一方面为在GASPAR系统中管理的PPRN编制（或修订）行政流程，另一方面为元数据表单N_PPRN_AAAANNNN中所描述的PPRN组成地理数据集。
