In addition to intervention and response, prevention, including a detailed, scientific mapping, assessment and management of risks, is increasingly important in disaster management. Risk assessment is particularly important in the case of natural disasters, as the threats posed by climate change have become increasingly unpredictable and intensified in recent decades. The climate of the Carpathian Basin is increasingly characterised by weather extremes and high-intensity weather events taking place within a short period of time. The number of hot days, drought years and heatwaves has increased. Over the last 30 years, the area has been increasingly affected by flood-like rainfall, the resulting extreme floods, storms, orcans and tornadoes. New, more intense climate events are a growing burden in managing disasters, both in terms of material and human resources management. It is therefore important to support investments in reducing specific disaster-related risk factors and increasing capacity in the field of management. In addition, a complex and detailed digital risk rating system (based on the current national risk assessment to prepare the risk chart) is needed to enable municipalities and disaster management bodies to prepare themselves properly and quickly and to take effective action. The main objective of the development project is to create a preventive and complex risk assessment system/network, an opportunity for all organisational elements involved in the disaster management system to better prepare for natural disasters caused by climate change. 1. Project MATERIES A) Establishing a harmonised, centralised and integrated risk assessment methodology at all Budapest and county disaster management directorates, as well as horizontal and vertical organizational elements of defence management, and setting up a compatible geospatial background (software/hardware) based on the basis of the existing geospatial system, which assists in disaster management decision support (before the occurrence of the disaster), the preparation plans, and provides a basis for spatial planning. The results are shared both inside and outside the organisation, with the necessary technical background. The system optimises resource management and dynamically modells changes in conditions (social, meteorological, climate, economic, institutional changes). B) Area identification and localisation of disaster risks, determination of the level of risks by type of hazard. c) Establish a single, transparent, interoperable, interactive, on-line risk, emergency and impact map catalogue covering the whole national territory. D) Establishing a higher level of disaster management through the use of geospatial decision support system, ensuring the efficient operation of the core activities in terms of costs and resources. e) Creating a climate change adaptation mechanism that is based on disaster management but can also be used for other policy decisions. The results of the project (methodology and map analysis) will be shared, they can be incorporated into the daily work of other public administrations in addition to disaster management organisations, so their application can have a positive impact on spatial and settlement development, economic activities, critical infrastructure protection, the operation of public institutions, public information and disaster management activities at local level well before the occurrence of natural disasters. (f) Based on the further development of the existing standards governing the risk assessment method. g) Developing a spatial information system infrastructure based on detailed spatial data (purchase of hardware and software, (h) Developing a Web Geospatial Analysis Module (or developing a central analytical module with the possibility to publish the results on the web). Preparation of dynamic municipal risk maps, identification of the level of risk per hazard type. j) Knowledge sharing, training for prospective end-users (direct target groups); K) Maintain protection practices for some priority settlements.
