DSB assesses response to extreme weather event Hans in Norway’s Nesbyen

The overall handling of last autumn’s extreme weather event, “Hans,” has been assessed as successful, largely attributed to early warning systems and proactive mobilization, according to Janniche Lim Cramer of the Directorate for Civil Protection and Emergency Planning (DSB). The DSB has evaluated the management of the disaster by reviewing 27 external reports, analyzing the events, and interviewing various stakeholders involved in rescue and cleanup efforts.

Despite acknowledging the strengths of the response, the DSB has identified 43 areas for improvement in their comprehensive 110-page report. They recommend significantly increasing funding for flood prevention efforts and suggest that the state should shoulder a larger portion of these costs, rather than relying on municipalities to cover their share.

The town of Nesbyen was significantly impacted by the flooding and landslides that struck southern Norway on August 7, devastating homes and leading to displacement for many residents. Although the municipality received funds to address the damages, Mayor Anne Kari Eriksen noted that they are still facing substantial financial liabilities, which restricts their budget for other essential services.

Nesbyen’s damages could have been far worse, with estimates indicating that losses might have doubled without effective water management strategies. A report from Multiconsult indicates that adjustments made in local waterways played a crucial role in minimizing damage.

The DSB has also emphasized the need for improved traffic information systems, stating that many roads were closed due to flooding and landslides, complicating evacuation and emergency response efforts. In light of these insights, proposals have been made to construct innovative flood defenses tailored for future resilience.
