Geoinformatics has emerged as one of the most transformative technologies in understanding, assessing, and reducing disaster risk in the context of a rapidly changing climate. The increasing frequency and intensity of natural disasters such as floods, cyclones, wildfires, droughts, and earthquakes require advanced and integrated tools for assessment, monitoring, and decision-making. Climate change assessment tools increasingly rely on geoinformatics, as it provides spatially explicit and temporally updated information essential for effective disaster risk reduction. The application of geoinformatics, which integrates Geographic Information Systems (GIS), Remote Sensing (RS), and Global Positioning System (GPS) with data modeling, spatial analysis, and simulation, allows for evidence-based planning and the development of strategies that can minimize vulnerabilities while enhancing adaptive capacity. By linking with climate models and assessment tools, geoinformatics supports the entire disaster risk management cycle—preparedness, mitigation, response, and recovery. One of the primary applications of geoinformatics in disaster risk reduction is hazard mapping and zoning. Remote sensing data combined with GIS techniques allow for the identification of areas susceptible to floods, landslides, coastal erosion, or forest fires. Satellite-derived rainfall data, digital elevation models, and land use information can be integrated into hydrological and climate assessment models to generate flood inundation maps. These maps provide local governments and communities with precise knowledge of flood-prone zones and help design appropriate land-use policies. Similarly, geoinformatics assists in preparing landslide susceptibility maps by analyzing slope, soil type, vegetation cover, and rainfall data. When linked to climate change assessment tools, hazard zoning becomes dynamic, reflecting changes in precipitation patterns, glacial melt, or sea-level rise projections, thereby offering more robust insights for long-term planning. Another important application lies in vulnerability and risk assessment. Disaster ______ ____ ________ __________ _______.
