The Citarum river, the longest and largest in West Java, has been rated the most polluted river the world. Over the years, successive governments have vowed to clean the Citarum river, but they mainly failed because such efforts were only partially done.
However, in February, after visiting the location, President Joko Widodo (Jokowi) issued a seven-year Citarum cleansing program with a final goal of making the river water drinkable by 2025.
The program will also be supported by the International Monetary Fund (IMF) and Asian Development Bank (ADB), which in 2009 had already committed to provide $500 million to fund the Citarum?s rehabilitation.
The Indonesian army is involved in carrying out the program to clear garbage and to grow trees in the critical lands in the riversides. The riverside areas have been heavily affected by the rapid industrialization in the region since the 1980s.
