The study attempted to identify suitable locations for urban green belts and green wedges in Chittagong city (CC). The mechanisms of the study were reviewing CC Master Plan, Detailed Area Plan (DAP), field observation, key informant interviews, and small groups discussions. Normalized Difference Vegetation Index was used for the vegetation classification from 1990 to 2021 at a 10-year interval. The urban built-up area of the Chittagong Development Authority (CDA) was 18.64 sq. km in 1990 while it became 139.74 in 2021. In 1990, dense vegetation was 153.21 Sq.km but it decreased to 19.39 Sq.km in 2021, because of rapid population growth and unplanned urbanization. A highly suitable site for the green belt was found in CDA coastal area. Besides, Kalurghat industrial zone, Chittagong Export Processing Zone, Nasirabad, and Baijid area were found appropriate for urban green wedges. Most suitable (83.60 sq. km) and moderately suitable (232.6032 sq. km) areas for the urban green belt were identified and in the coastal zone maximum suitable areas’ length was 57.61 km. &nbsp;The study concluded by urging for land-use zoning and the implementation of the urban green belt and green wedges, and raising voices against hill cutting by urban neighbourhood communities in CC.</p> ER -
