The world's megacities that are sinking 10 times faster than water levels are rising

The world's megacities that are sinking 10 times faster than water levels are rising | Chronique d'un pays où il ne se passe rien... ou presque ! | Scoop.it
Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.

 

A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.

In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.

The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.

In megacities, such as Jakarta, urbanization brings about many problems for local residents. The areas are crowded and residents get little to no income. An Australian organization works to help the people of Jakarta by giving them advice,food and helping where necessary. With this help, families are able to keep their spirits higher and hope that their children will live better lives than the ways that they were brought up.

Jakarta is the capitol of Indonesia and now has a population of over 28 million. Urbanization is bringing serious problems to Indonesia’s only mega city, such as poor access to clean water and housing, and overpopulation. Some people, including the young woman in this video are living with 16 or more people in one house. It seems the city is not providing enough affordable housing for its residents.

Tracy Galvin's curator insight, May 1, 2:25 PM

It is nice to see an organization that is not just blindly giving resources to people in need but actually empowering them and training them to be able to get the things they need through work. The women in this story describe how they have learned to make and sell things in order to take care of their families and they describe how empowering that feels.
