Disaster, as defined by the United Nations, is a serious disruption of the functioning of a community or society, which involve widespread human, material, economic or environmental impacts that exceed the ability of the affected community or society to cope using its own resources . Disaster management is how we deal with the human, material, economic or environmental impacts of said disaster, it is the process of how we “prepare for, respond to and learn from the effects of major failures” . Though often caused by nature, disasters can have human origins. According to the International Federation of Red Cross & Red Crescent Societies a disaster occurs when a hazard impacts on vulnerable people. The combination of hazards, vulnerability and inability to reduce the potential negative consequences of risk results in disaster .
Natural disasters and armed conflict have marked human existence throughout history and have always caused peaks in mortality and morbidity. This article examines the advances in the humanitarian response to public health over the past fifty years and the challenges currently faced in managing natural disasters and armed conflict .
Types of Disaster
According to the International Federation of Red Cross & Red Crescent Societies Natural Disasters are naturally occurring physical phenomena caused either by rapid or slow onset events that have immediate impacts on human health and secondary impacts causing further death and suffering. These disasters can be :
- Geophysical (e.g. Earthquakes, Landslides, Tsunamis and Volcanic Activity)
- Hydrological (e.g. Avalanches and Floods)
- Climatological (e.g. Extreme Temperatures, Drought and Wildfires)
- Meteorological (e.g. Cyclones and Storms/Wave Surges)
- Biological (e.g. Disease Epidemics and Insect/Animal Plagues)
The United Nations Office for Disaster Risk Reduction characterise Natural Disasters in relation to their magnitude or intensity, speed of onset, duration, and area of extent e.g. Earthquakes have short durations and usually affect a relatively small region, whereas Droughts are slow to develop and fade away and often affect large regions .
Man-Made Disasters as viewed by the International Federation of Red Cross & Red Crescent Societies are events that are caused by humans which occur in or close to human settlements often caused as a reults of Environmental or Technological Emergencies. This can include :
- Environmental Degradation
- Accidents (e.g. Industrial, Technological and Transport usually involving the production, use or transport of hazorous materials)
Some disasters can result from multiple hazzards, or, more often, to a complex combination of both Natural and Man-made causes which involve a break-down of authority, looting and attacks on strategic installations, including conflict situations and war. These can include :
- Food Insecurity
- Armed Conflicts
- Displaced Populations
- Extensive Violence
- Displacements of Populations
- Loss of Life
- Widespread Damage to both Societies and Economies
- Need for Large-scale, Humanitarian Assistance across Multiple Agencies
- Political and Military Constraints which impact or prevent Humanatarian Assistance
- Increased Security Risks for Humanitarian Relief Workers
Pandemic (from Greek πᾶν pan "all" and δῆμος demos "people") is an epidemic of infectious disease that has spread across a large region, which can occur to the human population or animal population and may affect health, disrupts services leading to economic and social costs. It may be an unusual or unexpected increase in the number of cases of an infectious disease which already exists in a certain region or population or can also refer to the appearance of a significant number of cases of an infectious disease in a region or population that is usually free from that disease. Pandemic Emergencies may occur as a consequenceof Natural or Man-Made Disasters. These have included the following Epidemics: 
Aspects of Disaster Management
The International Federation of Red Cross & Red Crescent Societies defines disaster management as the organisation and management of resources and responsibilities for dealing with all the humanitarian aspects of emergencies, in particular preparedness, response and recovery in order to lessen the impact of disasters .
"The outright avoidance of adverse impacts of hazards and related disasters "
UNISDR views Disaster Prevention as the concept of engaging in activities which intend to prevent or avoid potential adverse impacts through action taken in advance, activities designed to provide protection from the occurance of disasters . WCPT similalrily highlight that while not all disasters can be prevented, good risk managament, evacuation plans, environmental planning and design standards can reduce risk of loss of life and injury mitigation. The HYOGO Framework was one such Global Plan for natural Disaster Risk Reduction, which was adopted in 2005 as a 10 year Global Plan, signed by agreement with 168 Governments which offered guiding principles, priorities for action, and practical means for achieving disaster resilience for vulnerable communities .
"The knowledge and capacities developed by governments, professional response and recovery organizations, communities and individuals to effectively anticipate, respond to, and recover from, the impacts of likely, imminent or current hazard events or conditions" .
According to ICRC, Disaster Preparedness refers to measures taken to prepare for and reduce the effects of disasters, be they Natural or Man-made. This is achieved through research and planning in order to try to predict areas or regions that may be at risk of disaster and where possible prevent these from occurring and/or reduce the impact those disasters on the vulnerable populations that may be affected so they can effectively cope. Disaster preparedness activities embedded with risk reduction measures can prevent disaster situations and also result in saving maximum lives and livelihoods during any disaster situation, enabling the affected population to get back to normalcy within a short time period .
Minimisation of loss of life and damage to property through facilitation of effective disaster response and rehabilitation services when required. Preparedness is the main way of reducing the impact of disasters. Community-based preparedness and management should be a high priority in physical therapy practice management .
Disaster Response / Relief
"The provision of emergency services and public assistance during or immediately after a disaster in order to save lives, reduce health impacts, ensure public safety and meet the basic subsistence needs of the people affected" .
Focused predominantly on immediate and short-term needs the division between this response/relief stage and the subsequent recovery stage is not clear-cut. Some response actions, such as the supply of temporary housing and water supplies, may extend well into the recovery stage. Rescue from immediate danger and stabilization of the physical and emotional condition of survivors is the primary aims of disaster response/relief, which go hand in hand with the recovery of the dead and the restoration of essential services such as water and power .
Coordinated multi-agency response is vital to this stage of Disaster Management in order to reduce the impact of a disaster and its long-term results with relief activities including :
- Provision Food and Water
- Provision Emergency Health Care
- Prevention of Disease and Disability
- Repairing Vital Services e.g. Telecommunications, Transport
- Provision Temporary Shelter
Vulnerability of communities often cntinues for long after the initial crisis is over. Disaster Recovery refers to those programmes which go beyond the provision of immediate relief to assist those who have suffered the full impact of a disaster and include the following activities  :
- Rebuilding Infrastructure e.g. Homes, Schools, Hospitals, Roads
- Health Care and Rehabilitation
- Development Activities e.g. building human resources for health
- Development Policies and Practices to avoid or mitigate similar situations in future
How Physiotherapists Can Contribute
The WCPT provide advice on how physiotherapists can most effectively contribute in disaster situations highlighting the role for the profession in the aspects of disaster management described above.
Disaster Management Guidelines
The WCPT provide a comprehensive set of resources relating to disaster management, the role of the phsyiotherapy profession, advice for volunteering and the existing organisations involved:
