Chandigarh, India, is undergoing a significant ecological transformation as the site of the former Colony No. 4, once the city's largest slum cluster near Industrial Area Phase 1, is set to be developed into a 34.6-acre urban forest. This initiative follows the reclamation of nearly 65 acres of land by the Union Territory (UT) administration after the colony was demolished four years ago. The urban forest is part of the Centre's Nagar Van scheme, which aims to create green lungs in cities and promote biodiversity. The design includes an interconnected network of circular green zones, walking trails, cycle tracks, and multiple water bodies. Notable features will include a maze garden, bird-watching areas, and an open-air theatre for community engagement. The project is currently in the planning stage, with cost estimates yet to be finalized.
