Abstract
The aim of this contribution is to present the principles of risk analysis for territories that may have different sizes, e.g. municipalities, towns, districts and regions. The article summarises approaches to the issues of major risk assessment for stationary and mobile risk sources and natural disasters having effects on human health and life, property and the environment.
Vulnerability and risk mapping is usually carried out using the HVA (Hazard Vulnerability Analysis) method. For territorial assessment this method was promoted by the project SIPROCI (International Response to Natural and Man-made Catastrophes SIPROCI), which in the years 2004-2007 asked participating countries to predict, prevent and respond to natural and man-made disasters. One of the project outputs was the development of a uniform method for risk mapping.
The SIPROCI method of risk mapping works with the calculation of individual values of hazard, vulnerability and subsequently risk and their integration into the form of an index that can be simply graphically represented on maps. The SIPROCI method is relatively general – creates merely a certain methodical framework that is to be adapted for use in specific countries. During index selection, both national specifics concerning the organization of individual rescue services of risk sources and data available for the use of the method should be respected.
The application of the SIPROCI method in conditions of the Czech Republic and the pilot application of the method were carried out by the Fire and Rescue Service of the Moravian-Silesian Region. The article mainly deals with the presentation of a proposal for the method of optimized risk mapping, the results of which can be transferred through target indexes to a GIS map layer.
