The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.
For NRPPs, this entity may, for example, correspond to a watercourse, a geologically unstable area.

风险源（risk origin）指一类现实实体，其存在即会带来潜在风险。该风险源可通过名称进行表征，在部分场景下，还可借助用于定位该实际致险实体的地理对象来明确其具体指向。实体的空间位置与危险现象的相关知识，可用于界定风险池（risk pool）——即支撑RPP的风险暴露区域。
针对NRPPs而言，该实体例如可对应为水道、地质不稳定区域。
