Cyclone Shelter cum Schools in Coastal Zone 32
33
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 33
34
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 34
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 35
