KEY ELEMENTS OF RISK MANAGEMENT Planning and Preparation Response and

Reconstruction Risk

Identification Mitigation Risk Transfer Preparedness Emergency

Response Rehabilitation

and Reconstruction

Hazard assessment (frequency, magnitude and location)

Physical/structural mitigation works

Insurance/ re-insurance of public infrastructure and private assets

Early warning systems. Communication systems

Humanitarian assistance

Rehabilitation/ reconstruction of damaged critical infrastructure

Vulnerability assessment (population and assets exposed)

Land-use planning and building codes

Financial market instruments (catastrophe bonds, weather-indexed hedge funds)

Contingency planning (utility companies/ public services)

Clean-up, temporary repairs and restoration services

Macroeconomic and budget management (stabilization, protection of social expenditures)

Risk assessment (a function of hazard and vulnerability)

Economic incentives for pro-mitigation behavior

Privatization of public services with safety regulation (energy, water, transportation, etc.)

Networks of emergency responders (local/national)

Damage assessment Revitalization for affected sectors (exports, tourism, agriculture, etc.)

Hazard monitoring and forecasting (GIS, mapping, and scenario building)

Education, training and awareness about risks and prevention

Calamity Funds (national or local level)

Shelter facilities Evacuation plans

Mobilization of recovery resources (public/ multilateral/ insurance)

Incorporation of disaster mitigation components in reconstruction activities

Building and Strengthening National Systems for Disaster Prevention and Response: These systems are an integrated, cross-sectoral network of institutions addressing all the above phases of risk reduction and disaster recovery. Activities that need support are policy and planning, reform of legal and regulatory framework coordination mechanisms, strengthening of participating institutions, national action plans for mitigation policies and institutional development.

§  Establish problem domain, major goals, and organizational space !

§  Take an inventory of existing capabilities, resources, and management options !

§  Decision framework: logical relationships of general management objectives to technical risk!

§  Define management objectives, values and preferences!

§  Determine the risk ʻlandscapeʼ!

Risk Zone Process

RISK ZONE AREAS

Frequency of Fatalities Due to Man-Caused Events

Framework for hazard detection and judgment of evidence

Quantitative dominance of PPV and NPV by low frequency of hazard occurrence

Insensitive to false positive or false negative rates, the number of false positives will overwhelm the false negatives

as the frequency of hazard decreases

Lawrence Livermore National Laboratory LLNL-PRES-xxxxxx 15

§  For low frequency hazards, a large number of false positives can lead to ʻcomplacencyʼ!

§  For low frequency hazards, false negatives may be rare and difficult to detect, but consequences can be extremely severe!

§  When false positives or negatives are found, structured tests need to be performed to determine their causes!

§  Dominance of false positives over false negatives argues that trying to get to ʻzero riskʼ is destabilizing: rather, risk tradeoffs are inevitable!

§  False positive and false negative rates, and frequency of hazard are initially uncertain: there must be constant iteration and feedback among the data and these factors!

These issues entail the importance of the interplay and feedbacks among data and models to manage

uncertainty
