s occurred throughout the Indonesian capital of Jakarta and its metropolitan area on the early hours of 1 January 2020, due to the overnight rain which dumped nearly of rainwater, causing the Ciliwung and Cisadane rivers to overflow. At least 66 people have been killed, and 60,000 displaced in the worst flooding in the area since 2007.
Background
Floods have hit Jakarta several times in the past, including in 1621, 1654, 1918, 1942, 1976, 1996, 2002, 2007 and 2013. A significant contributing factor is that a substantial part of Jakarta is low-lying; some 24,000 ha of the main part of Jakarta are below sea level. Flooding can become severe if heavy rain coincides with high tides. When this happens, the high tides push water into low-lying areas coinciding with the runoff from rains in upland areas flowing down into the Jakarta area. Uncontrolled population growth in urban areas, poor land-use planning, and the lack of understanding among city residents and government about floods and its disaster risk exacerbate the impact.
Impact
Multiple floodgates were assigned emergency status due to the high water levels after the rainfall. From 18:30 WIB on 1 January until 12:00 WIB on 2 January, the government temporarily waived all toll road fees in Jakarta. At many parts of the city, water levels reached 30 to 200 cm. Some places, such as Cipinang Melayu, East Jakarta, water levels peaked at four metres. More than 397,000 residents had been evacuated to higher grounds. The government had designated schools and government buildings as temporary shelters. In several areas, evacuation efforts were hampered by rushing waters and blackouts. According to Indonesia's Meteorology, Climatology, and Geophysical Agency, more rain with thunderstorm and heavy winds is expected in the next three to seven days, which is likely to exacerbate the current flooding situation.
, officials reported the death toll at 66, due to landslides, hypothermia, drowning, and electrocution. Many parts of the city had been left without power, as the power was switched off for safety reasons by the state-owned electricity firm, PLN. It was the area's worst flooding since 2007 when the rainfall intensity was per day and 80 people were killed in 10 days.
Responses
planes were used in an attempt to break up the heavy rain. The Jakarta governor, Anies Baswedan, tweeted that the government would help all those affected by the flood. Baswedan has also told reporters that he would push new large-scale infrastructure projects, including a dam and a sluice, to prevent flooding again. Baswedan has publicly stated that "I want all the officials in the Jakarta administrations to make sure that all government buildings and schools are ready to be used as evacuation shelters. Prepare public kitchens, healthcare posts, medicines, sleeping mats, public toilets and other basic needs for evacuees," at the time of the flood. Indonesian PresidentJoko Widodo has tweeted that he will rebuild all public infrastructure with anti-flooding measures. Turkey's Ministry of Foreign Affairs stated that it's in full solidarity with the people of Indonesia and ready to provide any assistance that may be needed.
