Disaster Risk Reduction
Natural hazards are naturally-occurring physical phenomena caused by either the rapid or slow onset of events having atmospheric, geologic and hydrologic origins on solar, global, regional, national or local scales.
Natural disasters are the combination of hazards, conditions of vulnerability and insufficient capacity or measures to reduce the potentially negative consequences of risk. But natural disasters are not entirely "natural", for people can be agents of disasters. For instance severe flooding may be exacerbated by deforestation.
An increasing burden of risk is largely due to inappropriate development decisions. For example, populations are often concentrated on natural flood plains or along known earthquake fault lines, or in cities and settlements where houses and infrastructures are not safely built and where land use is poorly planned, leading to disastrous effects in the event of an earthquake, even a slight one.
What is not generally realized is that many disasters could have been greatly mitigated with adequate forethought and preparation, and that the cost of this mitigation would have been small compared to the cost of relief and recovery efforts. The main fields of action, as defined by the International Strategy for Disaster Reduction (ISDR), include risk awareness and assessment; knowledge development; public commitment and institutional frameworks; and early warning systems including forecasting, dissemination of warnings, preparedness measures and reaction capacities.
UNESCO is closely involved in raising public awareness and improving education about natural disasters, two certain ways of helping vulnerable populations to cope with risk.
4th International Disaster and Risk Conference IDRC Davos 2012
Integrative Risk Management in a Changing World - Pathways to a Resilient Society
Davos, Switzerland, 26-30 August 2012
Organized by the Global Risk Forum (GRF) Davos, this biennial conference will be held, as a global gathering to promote the integral risk management approach – across subject areas, professions, and sectors – encompassing scientific understanding with business, policy responses, the media and citizen participation, encouraging stronger ties with adequate public-private partnership models and devising approaches for moving towards a more truly integrated way of thinking about disaster and risks.
