RiskChanges: An open source tool for multi-hazard risk assessment and decision making
Organizer: Geoinformatics Center, Asian Institute of Technology – ITC, University of Twente
| This session will provide an advanced approach for multi-hazard risk assessment providing how risk changes over time, and how the information on changing risks can be used for disaster risk management. While risk in a particular area usually changes gradually over time due to land-use/land-cover change, population growth, and possibly climate change, however, risk status may also change abruptly due to a catastrophic disaster which may further adversely affect the environmental and socioeconomic conditions. We have developed an open-source tool for multi-hazard risk assessment and decision making, called “RiskChanges”, which allows the end-users and stakeholders to assess and evaluate the prevailing risks in a designated area and decide the best available risk reduction alternatives. To this effect, the end-users and stakeholders need to analyze not only the changes in hazards but also the changes taking place in elements-at-risk (buildings, population, transportation infrastructure, etc.), especially their vulnerabilities. In order to evaluate optimal risk reduction alternatives (structural and non-structural), the RiskChanges facilitates cost-benefit analysis for each of the alternatives. |
