Asia's booming cities must go green or risk disaster: ADB study (2)

(People's Daily Online)

11:42, August 18, 2012

This breakneck expansion has been accompanied by a sharp rise in pollution, slums, and widening economic and social inequalities which are causing rapid environmental degradation. Particularly disturbing are urban carbon dioxide emissions, which if left unchecked under a business-as-usual scenario, could reach 10.2 metric tons per capita by 2050, a level which would have disastrous consequences for both Asia and the rest of the world.

Rising urban populations mean that over 400 million people in Asians cities may be at risk of coastal flooding and roughly 350 million at risk of inland flooding by 2025. Unless managed properly, these trends could lead to widespread environmental degradation and declining standards of living.

The report notes that there is hope. The growth of cities can have many advantages, including critical masses of people in relatively small areas, making it easier and more cost effective to supply essential services like piped water and sanitation. Rising education levels, factories leaving cities, the growth of middle classes and declining birth rates typically associated with urbanization also have a broadly beneficial impact on resource use and the environment.
