Risk Reduction planners and organisations must understand the nature and probability or an occurrence that their people face. They must:

  1. Assess people, structure, service, activities;
  2. Understand specific vulnerabilities / capabilities to effectively design RR measures; and
  3. Know the general perception of risk and the importance people / organisation place on its reduction.

RR is required only when people and environment are impacted by something. The better the economic and social conditions are, the more chances of success of withstanding negative effects of a major event.

Going through this, you can find out vulnerability and hazards are closely related. Together they bring risk. Vulnerability is inversely related to the capabilities to withstand the effects. It has different shape: Human (lack of capability to cope – resist anticipated event; Structural (building damaged or an interrupted service)

Risk anticipated include: loss (life, property, service) over a period of time. They are understood differently by politicians, scientist, victims, insurance cies, MIL, salesman, ect…
