Climate change makes floods more likely and so the risks are greater. Research by Deltares has shown that economic development will be the most important factor driving the rising flood risk in the coming decades. More and more people will be living and working in high-risk locations and so the impact of flooding will continue to increase.
Many countries will have to switch from reactive policies to preventive, risk-based, flood risk management. That implies improving the resilience of specific locations by using new, innovative, methods to keep out the water, optimising spatial planning, and improving crisis management. Since 1 January 2017, the Netherlands has had new risk-based standards for flood risk management. The new approach looks not only at the probability of flooding but also at the impact, opening up opportunities for new solutions.
