Indonesia will build new capital city in Borneo as Jakarta sinks into the Java Sea.

A jungle-covered area on the east of Borneo island is set to be transformed into Indonesia's new capital city.
Concerns over the sustainability of the congested and rapidly sinking political centre of Jakarta prompted the need for a new capital. The relocation was announced today by President Joko Widodo.
The proposed location, near the relatively underdeveloped cities of Balikpapan and Samarinda, is a far cry from the crowded powerhouse which has served as Indonesia's financial heart since 1949 - and Widodo acknowledged that moving the country's capital to the island will be a mammoth and expensive undertaking.
But Jakarta's rapid expansion in recent years has presented myriad environmental, economic and safety concerns, prompting the government to look elsewhere and ease the strain on the massive metropolis.

Experts estimate the city is sinking by up to 25 centimetres a year whilst also being swallowed by a rising sea, with 95 per cent of the region's north predicted to be underwater by 2050.
"It's a disaster," Heri Andreas, a land subsidence expert from Bandung Institute of Technology, told 9News.
"If we are taking the groundwater the land becomes compacted, so the above becomes lower and lower.
"Several parts in Jakarta have already sunk about four metres now and in the future maybe we can have two or three metres more."
Giant seawalls have been built in some coastal parts but even they're sinking.

We keep pumping groundwater out or building cities and suburbs on swampland and the inevitable happens.
