Flood Protection: An Economically Sound Approach

A recent study by Swiss Re Institute highlights the economic advantages of flood protection measures over post-disaster rebuilding. With climate change and urban expansion, flood risks are rising, making adaptation crucial. The financial benefits of implementing protective structures like dykes and levees can surpass rebuilding costs by up to ten times.

In 2023, economic losses from natural catastrophes hit USD 280 billion, with USD 51.6 billion from floods. Protective strategies not only reduce these losses but also enhance safety and job creation. However, there's a funding shortfall. Swiss Re advocates for more private investment in climate adaptation.

Protective infrastructure yields variable benefits depending on the region, with dykes reducing flood damage by 60-90% in densely populated areas. Effective policy interventions are also essential for maximizing flood prevention value, particularly in emerging economies.
