The threat of flooding, soil degradation (land subsidence) as well as the rising sea water so the threat of several major cities of the world. Not possible when in 20 to 80 years ahead there is a city that is going to disappear from the map of the Earth.
By 2100, Bangkok predicted will become the second Atlantis. The capital of Thailand is sinking due to several factors, including climate change due to the greenhouse effect, rising sea levels, coastal erosion, and the shifting ground.
The predictions put forward by the head of Thailand’s National Disaster Warning Center Smith Dharmasaroja. By a number of parties, the predictions of Smith taken seriously. Earlier he had predicted the Tsunami around the Indian Ocean in 2004.
In addition, the layout of the city that are 1.5 meters below sea level caused the Bangkok always have a flood every year.
2. Ho Chi Minh City
One of the cities in South East Asia which threatened to sink was the Ho Chi Minh City. Each year, the height of flood waters rising as high as 2 centimeters.
The structure of the soil which was originally a swampy area which was later filled by skyscrapers, causing ground level Shanghai declined a half inches each year.
The need for building the skyscraper is swept up in the spiralling population of Shanghai. In 2001, the population of the city in the Yangze River estuary it amounted to 20 million people.
In 2008, a group of Greenpeace activists estimate that, by 2100, the city of Mumbai will be submerged by seawater. Rising up to 5 metres of sea water caused by melting polar ice.
In a report titled ‘ climate Migrants in South Asia ‘ Greenpeace caused by the melting of polar ice, increasing the Earth’s temperature by up to 4-5 degrees because of global warming.
In addition to a geographical location that is below sea level, the need for a high soil water suspected to be one of the causes of the sinking of the Mainland Jakarta. The population continued to increase into the main reason the need for ground water. In the span of 20 years ahead, it is estimated the number of inhabitants in the capital increase of up to 40 million people.
Hydrological experts from Netherlands, JanJaap Brinkman explains, if the process of water siphoned off continuously performed were not immediately stopped, in the late 19th century, Jakarta will sink.
“If the extraction (siphoned off) ground water was not immediately stopped, at the end of the century, Jakarta will sink to a depth of five to six metres,” he said theatlanticcities.com was quoted as saying.
