CPRD, with the support of British High Commission, Dhaka, implemented a research project to examine the long term variability of the sea surface temperature over the Bay of Bengal, distribution and frequency of tropical cyclone including depressions, and their impact on the coastal fishing communities. The research findings have been shared in a national seminar on 16 July in Dhaka. Mr Mesbah ul Alam, Secretary, MoEF was the chief guest in the seminar, while Mr Nick Low, Deputy High Commissioner, the British High Commission, Dhaka and Mr Jorge Nieto, First Secretary, Delegation of the EU were present as special guests. Dr Seleemul Huq, Director, ICCCAD presided over the seminar.

Analysis of SST over the period 1985-2009 showed that Night time SST to increase at a much faster rate than the Daytime SST. It has increased by 0.30-0.48° Celsius since 1985 at rates between 0.0126° and 0.0203° per year. Daytime SST is also found to have registered increase everywhere, ranging from 0.20° to 0.46° Celsius during the period, annual rate ranging from 0.0086 to 0.0191°. Prof. Sayedur Rahman, the lead researcher of this study said ‘If the trends found in this study are the true long term trends and the temperature increase continues in the future at similar rates we would expect a rise of Night time SST in the Bay of Bengal from 0.5° to 0.8 ° Celsius and daytime SST from 0.35° to 0.72° Celsius by 2050’.

Dr Shahadat Hossain, a member of this study team, said that the tropical cyclones during the last 25 year period have registered an increase in annual frequency by 0.0492 cyclones per year. During this period Bay of Bengal has produced on average 5.48 storms per year or once every 9.49 weeks. With an increasing rate above, we may experience a frequency of 7.94 storms per year or once every 6.54 weeks.

Md Shamsuddoha, Chief Executive, CPRD said though the coastal fishers are increasingly facing loss of livelihood opportunities due to ‘rough sea events’ but these are yet to be addressed in the national policy and strategy documents on climate change disaster risk reduction e.g. NAPA, BCCSAP etc.

Mr Nick Low, Deputy High Commissioner, the British High Commission, Special guest to this seminar hopes that national Disaster Risk Reduction (DRR) and Climate Change Adaptation policies will undertake appropriate programmes to reduce risks and livelihood vulnerabilities of the marginalized professional groups, what they are facing now, and will be facing increasingly in the coming years. Another special guest Mr Jorge Nieto, First Secretary, Delegation of the EU also emphasized on undertaking appropriate policies and programmes to reduce risk and vulnerabilities of people of this marginalized professional group

Mr Mesbah ul Alam, Secretary, MoEF and chief guest to the study sharing seminar said that the study findings and recommendation will serve as reference to show-up country’s vulnerability, especially vulnerability of a marginalized professional group of the country, to the global policy discourses and climate change negotiation at the UNFCCC process.

I hope that the international policy discussion as well as negotiation on climate change, especially the Loss and Damage Work Programme of the UNFCCC process will consider this issue, said Dr Saleemul Huq, who chaired and moderated the seminar.
