rises every morning and order to block the high tide when at the end of its house. this mobile dike protects an area that has sunk by more than three meters in a hundred years due to excessive pumping of water from the water table. beginning in one thousand nine hundred twenty is chinese all floridians have been measuring the steady sinking of the city. to study the phenomenon shanghai established a ground subsidence institute the only one of its kind in the world. lucian and. africa say yes until the one nine hundred sixty s. too much ground water was removed in shanghai. only this led to
regions are sinking faster than others one example is the coastline of the u.s. state of louisiana. is the mississippi delta new orleans is located in this area in here and most of the land surface has been disappearing over the last thirty years and our projections are as this will disappear in the next ten twenty thirty years it will be gone and so. when this disappears water from a hurricane can more readily impact the city of new orleans so the cities on the delta are at risk all of them. i mean without question and they re part of the list of one hundred thirty six areas at risk if we look at the twentieth century in many ways that probably for many cities the substance has been much much more important than climate and to sea level rise because we re talking about meters of change
so it is necessary to protect the levy some can get my carry out this industrial area in the area of talking about it but when my view we are not ready we are not prepared. the sea is rising climatic events are increasingly violent and big coastal urban areas are sinking subsidence is increasing the risk of flooding. all over the world the lives of many people are now threatened by these impending environmental disasters. so that led us to think well where what other cities are vulnerable to these kinds of
pretty much blocked disappear. you have international or you have enough for a state. floodways. i think if you look at the route course. it would lead us. to accommodate its growing population new housing was built in areas which provided drainage for the city after monsoons urbanization has transformed the landscape of bangkok rendering the city more vulnerable to flooding. we realize that the flooding is actually in some area where there was a you know factory that newser groundwater bumping up. and then we start to do the morning during the day in the area of bangkok and we found that thirty years ago the grass outside in red is about ten centimeters per
area used to be. ok but now. they re pumping. ok everywhere in bangkok the ground moves and subsides. you know if it is evidence of profit it ok. you can see barrier it s not even if there s like a way of it is because the barrier is a little kid over to foundation my way over here in between a barrier if not on the foundation is in the foyer so if criterion outside but. of the highway is out of site every year for years there department highway have to
