Green Map project to survey lakes, dams in Jakarta

Jakarta, Indonesia: Volunteers from the Jakarta Green Map project are planning to map lakes and dams in Jakarta and surrounding areas and record their conditions in the wake of the Situ Gintung disaster last month. The man-made earthen wall of the Situ Gintung reservoir in Tangerang burst last month, sending a deadly torrent of muddy water to nearby villages. More than 90 people were killed and hundreds of homes destroyed.

Jakarta Green Map coordinator Nirwono Joga said that there are around 200 lakes and dams in the Jakarta, Bogor, Tangerang, Depok and Bekasi area that needed checking. Nirwono, who is also the head of the Indonesia Landscape Architecture Study Group, has warned of a calamity, after conducting three surveys of Jakarta’s dams in 2005, 2007 and 2008.

Some 50 volunteers joined a workshop for the mapping of lakes and dams at the Komunitas Salihara cultural centre in South Jakarta on Saturday. “We hope to be able to survey around 50 to 100 lakes and dams,” Nirwono said, adding the map would be launched in July.

The volunteer-based project has released five editions of the Jakarta Green Map since 2001.
