Every second, the urban population grows by 2 people

Today, one in two people on the planet live in a city and every second, the urban population grows by 2 people. 93% of the urbanization occurs in poor or developing countries, and nearly 40% of the world's urban expansion is growing slums.

Urban population is projected to increase by almost 3 billion between 2010 and 2050

The world population is predicted to grow from 6.9 billion in 2010 to 8.3 billion in 2030 and to 9.1 billion in 2050. At the same time, urban population is projected to increase by 2.9 billion, to a total of 6.3 billion in 2050.

The frequency and intensity of water-related hazards is generally rising

Between 1991 and 2000 over 665 000 people died in 2 557 natural disasters of which 90% were water related. According to the UN Global Assessment Report, since 1900 more than 11 million people have died as a consequence of drought and more than 2 billion have been affected by drought, more than any other physical hazard. The frequency and intensity of such hazards is generally rising.

Asia-Pacific is the world’s most vulnerable region with respect to natural disasters

The Pacific’s small island developing states (SIDS) in particular are vulnerable to environmental natural hazards, such as tropical cyclones, typhoons and earthquakes turning into disasters. Climate change will further exacerbate the vulnerability of SIDS with anticipated sea-level rise and the risk of storm surge and beach erosion. One tropical cyclone can negate years of development efforts.
