Mitigation planning identifies policies and actions that can be taken over the long term to reduce risk, and in the event of a disaster occurring, minimize loss. Such policies and actions are based on a risk assessment , using the identified hazards , vulnerabilities and probabilities of occurrence and estimates of impact to calculate risks ...
Disaster risk reduction (DRR) is defined by United Nations Office for Disaster Risk Reduction (UNDRR) as those actions which aim to "prevent new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience and therefore to the achievement of sustainable development".
The HFA was conceived to give further impetus to the global work under the International Framework for Action for the International Decade for Natural Disaster Reduction of 1989, and the Yokohama Strategy for a Safer World: Guidelines for Natural Disaster Prevention, Preparedness and Mitigation and its Plan of Action, adopted in 1994 and the ...
A natural disaster is the very harmful impact on a society or community after a natural hazard event. Some examples of natural hazard events include avalanches , droughts , earthquakes , floods , heat waves , landslides - including submarine landslides , tropical cyclones , volcanic activity and wildfires .

The First World Conference on Natural Disasters in Yokohama, Japan from May 23 to 27, 1994, adopted the Yokohama Strategy for a Safer World: Guidelines for Natural Disaster Prevention, Preparedness and Mitigation and its Plan of Action, endorsed by the UN General Assembly in 1994. It was the main outcome of the mid-term review of the ...
Mitigation strategies are supported by state government and federal programs, in line with the Disaster Mitigation Act. The need for hazard mitigation has become more widely recognized over the past few years, due to the large number of natural hazards that have occurred in the U.S. and the increase in the costs to achieve post-disaster recovery.
After a natural disaster, certain chemicals can become more prominent in the environment. These hazardous materials can be released directly or indirectly. Chemical hazards directly released after a natural disaster often occur at the same time as the event, impeding planned actions for mitigation.
Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience.
