Indonesia’s president said that he wants to build a large sea wall around Jakarta. The goal is to prevent the low-lying capital from being flooded by the sea. But, President Joko Widodo and his government may not have a lot of time. Some experts forecast that, at the current rate, one-third of Jakarta might be under water by 2050. The crisis facing the city is the result of many years of uncontrolled development. There has been little city planning. Many politicians have served business interests and not the public’s interest. Many of the city’s millions of people take ground water from wells because the water pipe system does not serve all areas. This has caused the city to slowly sink as the ground water beneath it disappears.
