Disasters and DevelopmentDisasters and Development
Major natural hazards have larger consequences in developing countries than in industrialized nations
Factors related to relatively-lower development levels contribute to magnify such consequences
The impact of disasters on long term development prospects is higher in developing economies
31 Dec 2003 RJ 3
Disasters and Development..Disasters and Development..
In recent years, more than 90 per cent of deaths caused by disasters in the world have occurred in developing countries
The effects of major disasters have negatively affected living conditions and development prospects in said countries
During the past three decades, disasters have caused more than US$ 50 billion in damages and losses in selected countries of the Latin America and Caribbean region, and caused lower economic performance and living conditions
31 Dec 2003 RJ 4
Disasters and Development...Disasters and Development...
Recent, major disasters have imposed heavy burdens on the economy and society of Latin America and the Caribbean
As an example, Hurricane Mitch in Honduras
- Caused damage and losses that were equivalent to 70% of GDP in 1998
- And economic performance in 1998 and subsequent years suffered a serious setback

Damage, Losses, and Damage, Losses, and Macroeconomic EffectsMacroeconomic Effects
Direct Damages: total or partial destruction of assets immediately following a disaster
Indirect Losses: Modifications to production flows or to the provision of essential services
Macro-Economic Effects: Modifications to performance of main aggregates of the affected economy

Hazard, Vulnerability and RiskHazard, Vulnerability and Risk
Hazard is the probability of occurrence of a natural event that may cause significant damages, losses and other economic effects
Vulnerability is the propensity that a community may have to sustain human losses, physical damage and economic losses due to the occurrence of a major natural event
Risk is the probability that damage and losses may occur as a result of the occurrence of a natural event of a given magnitude, in a given time and place
31 Dec 2003 RJ 10
RiskRisk
Risk is the result of the combination of the occurrence of a natural hazard and of a vulnerable human settlement or activity

Disaster Risk ManagementDisaster Risk Management
Risk management is a process of analysis and quantification of the probability that damage and losses are produced so that prevention and mitigation measures can be implemented to reduce risk
31 Dec 2003 RJ 12
Disaster Risk ManagementDisaster Risk Management
Risk management involves implementing two types of activities:
- Planning of vulnerability reduction- Adoption of protection measures against
potential economic damage and lossesA comprehensive risk management scheme
should include:- Ex Ante measures undertaken before a
disaster- Ex Post measures carried after a disaster
occurs

Risk Transfer: to reduce financial impact of disasters to levels commensurate with country’s capacity for reconstruction, when mitigation and prevention measures are unable to avoid disasters
Ex Ante financial sources:
• Without risk transfer
• With risk transfer

Reconstruction requires:• Diagnosis on direct damages and indirect
losses caused by disaster • Formulation of strategy and plan for
reconstruction• Specific sectoral project formulation • Financing, local and internationalFinancing of reconstruction usualley
undertaken by drawing on more immediately available and lower cost resources

Who Bears RiskWho Bears Risk
Governments are (non consciously and for moral reasons) assuming risks beyond their ownership and, at times, beyond their financial capacity:
• Infrastructure (roads and bridges, ports and airports, hospitals and schools, office buildings, and water and energy facilities, when not privatized)
• Housing for the poor
31 Dec 2003 RJ 27
Who Bears Risk..Who Bears Risk..
The private sector normally bears risk on:
• Property and production, usually resorting to insurance
• Privatized essential services of electricity, water supply, telecommunications
• Housing, except for the lower income population
31 Dec 2003 RJ 28
Disaster Risk ManagementDisaster Risk Management
Decision makers do not perceive the need for undertaking disaster risk management due to:
- Difficulties in accurately and reliably forecasting the possible occurrence of natural events
- Estimated return periods are longer than their periods of office
Thus, the need for risk management only becomes obvious when a major disaster – having high social, economic, environmental and political consequences – or when succesive disasters occur

Results of reconstruction schemeResults of reconstruction scheme
After completing reconstruction of the 2001 earthquakes -- resorting to fresh and re-oriented loans, using monetary reserves, and having refinanced short-term loans through long-term ones -- El Salvador has reached a total debt that is equivalent to 47% of its GDP, or 4.6 billion US Dollars
