Asia and the Pacific

  • Asia now holds 61 per cent of the global population and its share of the global urban population has risen from 9% in 1920 to 48% in 2000 and is expected to rise to 53% by 2030
  • By 2015 Asian developing countries will hold three of the world’s five largest urban agglomerations: Mumbai, Dhaka and Delhi
  • Of all the world regions, developed and developing, Asia ranks lowest in almost all types of crime
  • Of the 10 countries most hit by natural disasters in 2005, 7 are in the Asian continent
  • Australia is the driest continent, and has one of the most variable rainfall climates in the world

UNESCO 2006; UNISDR 2005

slide4

Explosive growth in Beijing, China

Beijing, the capital city of China, is experiencing explosive growth since economic reforms in 1979

  • 1978: Beijing in 1978
  • 2000: Extent of urban expansion is clearly visible

Earthquakes and Tsunamis

  • According to long-term records (since about 1900), we can expect about 18 major earthquakes (7.0 - 7.9 on the Richter scale) and one great earthquake (8.0 or above) in any given year (NEIC 2003)
  • The number of earthquakes and tsunamis resulting in fatalities has increased approximately in proportion to global populations
  • The growth of giant urban cities near regions of known seismic hazard is a new experiment for life on the Earth
  • Tsunamis are a threat to life and property for all coastal residents
slide12

A city destroyed by earthquakeBam, Iran

A 6.6 magnitude earthquake struck southeastern Iran on 26 December 2003, killing over 40 000 people, injuring 16 000, leaving 70 000 homeless and destroying much of the city of Bam, the earthquake’s epicenter
