Conclusion and Recommendations
• Coastal zone has great importance to protect the shoreline of the Bay
• Northern part is resourceful & biodiversity rich,very fragile & prone to pollution
• Industries, agriculture & ports are major sources• Ship breaking, shrimp culture are great threat• Destruction of mangroves increasing vulnerability

Conclusion and Recommendations
• CHT plays important role in coastline management• Dams destroying the hill forests & water-flows• Indiscriminate use of Chemicals and upstream in
agriculture destroying perennial streams Causing marine & terrestrial biodiversity loss • Hill cutting, shrimp hatchery and unplanned
structures damaging Cox’s Bazar sea beach

35
Conclusion and Recommendations
• Pollution from ship-breaking, ports & shrimp culture should be stopped
• Deforestation, hill-cutting, over-fishing unplanned construction must be controlled
• Defense systems against cyclones, tidal surges, erosion should be built up
