Chapter 1 Overview of Urban Development and Associated Risks

Climate change is happening now. Climate-induced disasters are occurring in the Asia Pacific region, where a distinctly increasing trend has been observed in recent decades. This shows that the region is the most disaster prone, compared with other parts of the world. Studies on the causes of disaster in many affected regions suggest that in a typical disaster, cities with high population density see increases in mortality and number of people affected. Increased economic losses within the region are also inevitable. In most Asian countries, 65–90% of economic activities are concentrated in urban areas. Estimates indicate that two out of three people on the earth will live in urban areas by the year 2030. Unless appropriate measures are taken in these urban communities, disaster incidents will continue to increase. Urban communities are a main player to confront this increasing trend of climate-induced disasters.
