Decision basis and risk assessment due to climate change Spatial planning Precautionary measures Adaptation activities New possibilities Photo: Bengt Olof Olsson
Decision basis -natural risk management Information gathering Geology/geotechnical prerequisites Protecting structures Current and historical hazards Assets (economic, environmental etc.) Analysis incl climate change Potential hazards Potential risk areas Problem analysis and risk assessment Basis for spatial planning Decision basis for adaptation measures Need for precautionary measures Constraints for development Natural hazards ”hot spots” Protective measures Adaptation activities
Climate adaptation – build environment identify vulnerability and risk levels adaptation and reinforcement permanent and/or temporary reinforcements Foto: SMHI
Climate change and spatial planning - planning conditions (soil and water) local and regional perspective long term planning focus precautionary measures security and flexibility Foto: SMHI
