JAKARTA, INDONESIA - APRIL 27: A section of the new offshore seawall on April 27, 2017 in Jakarta, Indonesia. Jakarta, one of the world's most densely populated cities, is also one of the fastest-sinking cities in the world under the weight of out-of-control development and rising sea levels caused by global warming. Experts say that if nothing is done, parts of Jakarta will sink five metres by the year 2025 so the government is proposing a $40 billion project to tackle the problem by building a 15-mile seawall and 17 artificial islands around Jakarta's northern coastline. The seawall along the coast and across Jakarta Bay began as an immediate solution while President Widodo's administration continues to work on the details of the major project nicknamed Garuda. Increasing floods and severe storms due to rising temperatures and climate change have threatened the mostly poor residents of Jakarta's northern coast with the loss of their homes as reports indicate the problem has been exacerbated by massive overuse of groundwater causing subsidence.
