Jakkur Lake is an example of collective action-the implementation of a node for social and scientific innovation to help improve the lake ecosystem and social relations among stakeholders.

Jakkur Lake is one of the largest lakes in the grid of man-made lakes in the city and is located in the north eastern part of Bengaluru. Unplanned development in the area surrounding the lake had led to solid waste filling its feeder channels. This choked the natural watershed so much that the lake resembled a dumping yard.

Jakkur Lake interestingly has a very well designed wetland system. According to the USEPA, a wetland is a complex assemblage of water, substrate, plants(Vascular and algae), litter (primarily fallen plant material), invertebrates and an array of micro-organisms( most importantly bacteria).
