As urban areas expand, trillions of dollars worth
of infrastructure, industrial plants, office buildings
and homes will be increasingly at risk of flooding.

Flood risk increases mainly due to population
and economic development
Overall, more extreme precipitation will increase
the risk of river flooding. Without additional
flood protection and following the projected
strong increase in economic value in flood-prone
areas, the focal point of damage will shift to Asia.
In 2010, around 1 billion people around the world were living in flood-
prone areas, potentially exposed to either river or coastal flooding.
This number is projected to increase to over 1.6 billion by 2050.
