Risk is the probability that exposure to a hazard will lead to a negative consequence, or more simply, a hazard poses no risk if there is no exposure to that hazard. Risk is a combination of hazard, exposure and vulnerability. [11] For example in terms of water security: examples of hazards are droughts, floods and decline in water quality. Bad ...
Its policy goals and objectives are defined in disaster risk reduction strategies and plans. [2]: 16 The term disaster risk management (DRM) is often used in the same context and to mean much the same thing. That is a systematic approach to identifying, assessing, and reducing risks associated with hazards and human activities.

Firefighters are exposed to risks of fire and building collapse during their work.. In simple terms, risk is the possibility of something bad happening. [1] Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences.

According to the British sociologist Anthony Giddens, a risk society is "a society increasingly preoccupied with the future (and also with safety), which generates the notion of risk", [3] whilst the German sociologist Ulrich Beck defines it as "a systematic way of dealing with hazards and insecurities induced and introduced by modernisation itself".
Risk is a function of exposure and hazard. For example, even for an extremely toxic (high hazard) substance, the risk of an adverse outcome is unlikely if exposures are near zero. Conversely, a moderately toxic substance may present substantial risk if an individual or a population is highly exposed. [2] [3]
The Sendai Framework for Disaster Risk Reduction (2015–2030) is an international document that was adopted by the United Nations (UN) member states between 14 and 18 March 2015 at the World Conference on Disaster Risk Reduction held in Sendai, Japan, and endorsed by the UN General Assembly in June 2015.
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
