Future climate change strategy and action plan
• Bangladesh government is committed to strengthen the country’s resilience to climate change, reduce risks posed to national development; and development of the country along a low-carbon growth path.
• The Bangladesh Climate Change Strategy and Action Plan (BCCSAP) is a 10-year program (2009-2018).

Conclusion
• Biodiversity of the coastal region is lost, shortage of fresh water, alteration of fish physiology , growth and behavior.
• Climate change has both positive and negative impacts on coastal aquaculture in Bangladesh, salinity intrusion into freshwater destroy the native species where as it also facilitates the shrimp farming.
• Different policies regarding environmental issues is essential in the coastal regions and awareness creating program should be conducted to overcome the adverse climatic situation
