Coastal Belt of Bangladesh (Statistics)• Area: 20% of total land • Area: 30% of cultivable land • Shoreline : 710 km• Total Coastal Districts: 19• Costal Population :35 Million• Highly exposed to Disaster :8 Million• Land Erosion: 3199 ha/yr

Coastal Districts of Bangladesh

Coastal Morphology

Impacts of Climate change on Coastal Zone• Cyclone/Strom Surge: Increased frequency and Intensity• Floods: Increased frequency and magnitudes• Riverbank and coastal erosion : increasing• Water logging and inundation due to sea level rise• Salinity ingression

Policy and Strategy of Govt.• Coastal zone policy 2005• National Adaption Program of Action (NAPA) 2005• Bangladesh Climate Change Strategy and Action Plan (BCCSAP)2009 CDMP(Comprehensive and Disaster management program) Infrastructure Mitigation and low Carbon Development Research and Knowledge development Capacity and institutions

• Bangladesh Climate Change Trust Fund(BCCTF)• Bangladesh Climate Change Resilience Fund (BCCRF)

Key Achievements

• Coastal Embankment Rehabilitation project (CERP)1991• Char Development and Settlement Project (CDSP)1994• More than 2000 Cyclone Shelter with radio communication network • More than 50,000 hectares of new land reclaimed along Noakhali

coast through Meghna Cross Dam.

Key Challenges• Declining viability of many distinctive and threatened coastal ecosystem

including Sundarbans, coastal wet lands• Wide spread pollution and resource degradation• Poor access to many forms of infrastructure and technologies with respect

to coastal areas• Surface and subsurface Stalinization• Poor resource management• Rapid decline of resources : marine fisheries, Mangroves and Fresh water

resources• Sea level rise and Rain fall pattern change

Key Initiatives • Generation of information and filling Knowledge gap through Coastal resources survey Integrated Coastal Resources Database Modeling Tools Information Dissemination Capacity Building

• Harmonizing sectoral Policies and laws• Appreciation of ecosystem linkages• Improved Governance

Conclusion

Coastal zone management : • sustainable development• conservation of biodiversity • Conservation of natural resources .
