Bambang Brodjonegoro said President Joko Widodo had chosen to relocate the capital in "an important decision"... Jakarta, home to over 10 million people, is sinking at one of the fastest rates in the world... Researchers say that large parts of the megacity could be entirely submerged by 2050. North Jakarta sunk 2.5m (eight feet) in 10 years and is continuing to sink an average of 1-15cm a year... But President Joko Widodo has achieved ambitious infrastructure building in his five years in office, so he may well be the man that finally does it.
