Indira Bhende’s collection of photographs reveal the dismal tale of the Dahisar River’s decline from a thriving water body to gutter-like state. A 1943 painting by Sawlaram Haldankar shows a bridge built by the Portuguese over it. The pastoral setting is contrasted by modern-day scenes of the trash-chocked river that form exhibits at a two-day community workshop that kicked off on Thursday, hosted by five organisations at the Maharashtra Nature Park (MNP) in Dharavi. Bhende, the first Dahisar resident to initiate a campaign to save the urban river, was supported by 3D models by participating architects.
