Waste 'Edam' - Neighbourhood Waste Centre
I collect waste and then turn it into upcycled products, along with the students and residents in the community. Who knew waste could help me realise my creative and business potential!
Govt Law College - Campus Community Living
Living Shoreline & Indira Priyadarshini Park
The lush coastal edge, water bodies, and community spaces take me back to Kochi’s past...It is uplifting to see developers transform the skyline, which strengthens our resilience towards climate change. I am glad that the living shoreline protects from coastal erosion, creates an ecological park system and also a real-estate boon.

Community Managed Groves Did you know! Community groves have always been a part of Kerala’s traditional rural landscape (Kavus) & remnants of it are still evident in the fabric of Kochi. As the guardian of one such grove, I feel empowered and environmentally conscious. In the groves, we grow our own food, recycle waste into biogas, recharge our wells.
