Solution for Reducing the Water and Waste Footprints of Megacities

The United Nations estimates that the number of megacities with a population of more than 10 million will triple from 20 in 2003 to 61 in 2015. It is estimated that more than nine tenths of urban growth will occur in developing nations, with four fifths of urban growth occurring in Asia and Africa.

Raise public awareness about waste and water footprints.

Many societies tend towards lifestyles with higher resource use, yet the ecosystems that provide the desired goods and services needs to be sustained. It is a major challenge to decouple economic growth and the growth of waste/water footprints. To meet this challenge, education will play an important long-term role in raising awareness of finite resources and encouraging behavioral change.
