  6. Decision basis and risk assessment due to climate change • Spatial planning • Precautionary measures • Adaptation activities • New possibilities Photo: Bengt Olof Olsson

  7. 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

  8. Foto: SMHI Climate adaptation – build environment • identify vulnerability and risk levels • adaptation and reinforcement • permanent and/or temporary • reinforcements

  9. 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
