ENVIRONMENTAL RISK ASSESSMENT Session 8 RISK MANAGEMENT ParichartVisuthismajarn, Dr. phil., Asst.Prof. Faculty of Environmental Management Prince of Songkla University
Objectives • Risk management definition • Approaches to risk management • Aspects of risk management • Principles & challenges of risk management • Risk Tradeoffs • Impact of perception • Urban air pollution • Remedial action risk management process • Use of risk management in the military • Labeling systems for risk management (DOT, NFPA) • Management systems – ISO 14001 • Environmental audit process • Qualitative risk management systems, several examples
Risk management • Risk Management is reducing risks to an acceptable level, which is? • Zero risk? – no risk is acceptable – unrealistic • Acceptable risk? – who defines what is acceptable • De Minimus and De “Manifestis” Risks • de minimus, that is trivial risks • Often considered less than 1 in 1,000,000 risk • de “manifestis” that is obnoxious risk • Controlled without regard to cost; risk greater than 1 in 1000 • Risk Assessment complicates management by exposing • Uncertainty and variability • Differences in stakeholder understanding and perceptions • multiple perspectives make consensus building difficult

Risk = Hazard x Exposure • If this is true, then risk management is a function of reducing or eliminating: • Hazards • Exposure • Consequences (harm) of expsoure • Risk management must be formulated in the context of the culture • Socio-economic • Socio-political
Risk Management • Involves decision-making that incorporates: • Prioritizing risks • Determining acceptable level of risk • Determining resources to reduce risks to an acceptable level • Determining the greatest benefit for the resources to be expended • Planning • Implementing • Monitoring and evaluating effectiveness

Use of Risk Management in the Military • The use of risk assessment methods in the military varies • Quantitative Health Risk Assessment follows generally accepted principles • Qualitative methods are also used for decision-making
Six Steps of Risk Management in Military • Step 1 • IDENTIFY HAZARDS DURING MISSION ANALYSIS • CONDITIONS THAT HAVE THE POTENTIAL OF POLLUTING THE AIR, SOIL, WATER, OR DEGRADE NATURAL CULTURAL RESOURCES • Step 2 • ASSESS THE PROBABILITY OF ENVIRONMENTAL DAMAGE AND VIOLATIONS • ENVIRONMENTAL RISK ASSESSMENT MATRICES • Step 3 • MAKE DECISIONS AND DEVELOP MEASURES TO REDUCE HIGH RISKS http://155.217.58.58/cgi-bin/atdl.dll/gta/5-8-2/050802_top.htm
Six Steps of Risk Management in Military • Step 4 • BRIEF THE CHAIN OF COMMAND AND APPROPRIATE DECISION MAKERS • PROPOSED PLANS AND RESIDUAL RISKS • Step 5 • IMPLEMENT ENVIRONMENTAL MEASURES • INTEGRATE THEM INTO PLANS, ORDERS, SOPs, TRAINING PERFORMANCE STANDARDS, AND REHEARSALS • Step 6 • SUPERVISE AND ENFORCE ENVIRONMENTAL STANDARDS • TRAIN TO THESE STANDARDS http://155.217.58.58/cgi-bin/atdl.dll/gta/5-8-2/050802_top.htm

Social Risk Management Framework:Basic thrusts: • The poor are typically most exposed to diverse risks • traditional and modern • The poor least equipped to deal with these risks • The poor are most vulnerable • High vulnerability makes them risk averse and thus unable or unwilling to engage in higher risk/high return activities • SRM seeks to account for multiple sources of risk and their characteristics to address vulnerability • Operates with multiple strategies (prevention, mitigation, coping) and arrangements (informal, market-based, public) to deal with risk • Attempts to match the multiple suppliers of risk management instruments (such as households, communities, NGOs, and governments) with key demand groups (formal, informal-urban and informal-rural workers) Adapted from Holzmann, 1998

Environmental Pollution Deforestation Nuclear disaster Adapted from Holzmann, 1998
Risk Management Strategies • Prevention Strategies - to reduce the probability of down-side risk • Mitigation Strategies - to decrease the impact of a future down-side risk • Portfolio diversification • Insurance • Hedging/Risk exchange • Coping Strategies - to relieve the impact once the risk (the event) has occurred Adapted from Holzmann, 1998
Risk Management Arrangements • Informal arrangements, e.g. • marriage, real assets, mutual community support • Market-based arrangements, e.g. • cash, bank deposits, bonds and shares, insurance contracts • Publicly provided or mandated arrangements • social insurance, transfers in cash and kind, subsidies and public works Adapted from Holzmann, 1998
