Ivaniuta S. Scientific fundamentals of assessment of risks and threats for ecological security of Ukrainian regions

Scientific fundamentals of assessment of natural and man-made risks and threats to improve the structure of ecological monitoring and improvement of ecological security of Ukraine's regions are presented. New methods for assessment risks and threats to regions' ecological security are developed. With the use of these methods the ranking of regions by a combined index of security are carried out. The estimation of the speed of changing in time of security features of Ukraine's regions for each object of protection is done. The changes of natural and technogenic threats are discovered with the aim of improvement decision-making processes in the field of risk reduction for ecological security of regions. Methods of inclusive assessment of threats to security operation of critical transport infrastructure of the criterion of their location in areas of sustainable space-time display of dangerous exogenous geological processes have been developed. A comprehensive assessment of actual threats of engineering and geological origin for the safe operation of the main-pipelines, railways, international transport corridors, bridges at regional level is completed. Software implementation of methods developed for comprehensive assessment of security threats operation of critical transport infrastructure with the use of GIS technology at the regional level is realized. A graphical user interface, capacities of the operating environment and the practical needs of the operator is developed. It provides execution sequence of actions of the operator to assess threats to the security of critical transport infrastructure: the choice of region for research, selection of type of critical transportation infrastructure, selection of dangerous exogenous processes, and output of evaluation.
