The Water, Megacities and Global Change conference organised by ARCEAU IdF and devoted to the theme of water in megacities, will be hosted by UNESCO in its Paris HQ, 2015 - December 1st to 4th, during the first week of the COP21.
Since 2011 and for the first time in its history, the world population as a whole is now mainly concentrated in urban centers. In 2025, more than one billion people will be living in about one hundred very large cities. Megacities, those cities with more than 10 million people, are multiplying rapidly.
Beyond demographic issues, climate change in these megacities will require very important measures for adaptation and profound transformations to avert potential coming crises like: access to water and sanitation for all, service equity, economic viability, solutions flexibility, and innovative response to unprecedented evolution
