Disaster and crisis preparedness

Preparedness involves initiatives designed to mitigate or reduce the impact of major risks and disasters and thus create resilience. It requires foresight and planning. One can distinguish between long-term and short-term preparedness activities. The former can be divided into structural, semi-structural, nonstructural, and environmental categories. Structural preparedness involves building defenses and strengthening buildings and infrastructure against the physical impact of disasters. Although widely used, it is expensive and usually does not provide complete protection against the effects of disaster. Semi-structural measures include flood barriers that can be dismantled and the designation of areas for the storage of floodwater. Nonstructural measures comprise land-use planning (including interdiction on settlement and other uses in areas of high hazard), insurance, and emergency planning. The last of these is designed to ensure that resource usage in crisis situations is optimized in favor of responding effectively to the impact. Nature-based or ecological measures involve enhancing the power of natural systems to amortize the impact of disaster. Emergency preparedness configures the “architecture” of response, including command centers, control systems, hazard monitoring networks, systems designed to warn the public, and plans to evacuate people. In parallel to emergency planning, business continuity management is a form of preparedness that is designed to ensure the continued functionality of organizations. It may include measures to protect their reputation among clients, customers, and suppliers, and their market position or stock market quotation. Preparedness for pandemics can be considered as a special case, in which medical and epidemiological preparations are accompanied by preparedness measures to deal with the profound socioeconomic changes that a pandemic brings to society. Preparedness is also important during the phase of recovery from disaster. This period involves a “window of opportunity” in which official and public sensitivity to the problem can be used to improve safety by reconstructing to higher standards than existed before the disaster and incorporating new safety measures. In terms of resilience, this is a “bounce-forward” strategy, sometimes known as “build back better,” rather than a “bounce-back” one that would risk restoring preexisting vulnerabilities. Disaster risk is particularly dynamic in the modern world, thanks to major changes in the magnitude and frequency of environmental hazards, large increases in the vulnerability of people and assets, and anthropogenic degradation of natural environments. Preparedness is thus a major imperative that is greatly needed if very large losses are to be avoided
