Why is displacement risk from floods so high in urban settings?

Much of the world’s population live in towns and cities. Estimates are that by 2050 66 percent of us will live in urban settings, many of us in informal settlements.

Floods are the most common hazard to affect towns and cities around the world.

More than 17 million people are at risk of being displaced by floods each year. Of these, more than 80 per cent live in towns and cities. Flood displacement risk is highest in South Asia, East Asia, and the Pacific, and high and rapidly increasing in Sub-Saharan Africa.

Urban planning and funding for urban development must take natural hazards and climate change related risks, especially flooding, into consideration to prevent future disasters.

Mitigating the risk of urban flooding would considerably reduce future disaster displacement. The Internal Displacement Monitoring Centre’s tool for assessing disaster displacement risk in urban settings is a great place to start.
