Abstract

Bangladesh, as a low-lying country experiencing the adverse impact of climate change and sea level rise to a greater scale. Especially, people of the coastal area which constitute major part of the country has been experiencing this impact by means of loss of their agricultural production, life and livelihood. This paper analyses the dynamic of changes of surface water content for two coastal areas namely Satkhira and Bagerhat between 1984-2015 by using the analytical tool of Google Earth Engine and adopting the methodology developed by Pekel et al. 2016 and explore the relation of these changes with climate change and sea level rise induced impact by means of literature review. Study result shows that there is higher extent of surface water occurrence in Satkhira than Bagerhat in the mentioned study period. Regarding impact, both areas are having trouble to agricultural production due to salinity intrusion, water logging or long term inundation of crop land and different climatic extreme events. However, there is a necessity to carry out a future study to project long term adverse impact of sea level rise on agriculture sector in coastal area based on their exposure under different sea level rise scenario and sustainable adaptation solution should be addressed under those circumstances.

Biography

Mr. Roy is a PhD student working in University of Lisbon, Portugal. His research area focuses on Sea level rise impact modeling in coastal areas primarily focusing on Bangladesh. He holds a Double Master degree in Forest Sciences awarded by University of Padova under Erasmus Mundus Scholarship Program. He has interest in the field of climate change impacts, mitigation and adaptation specifically on Nature based Adaptation strategies.

About the Association

The Australian Coastal Society (ACS) was initiated at the Coast to Coast Conference in Tasmania in 2004. The idea was floated as a means for those interested in coastal matters to communicate between conferences and where possible take resolutions of the conference to appropriate levels of government.

The idea was discussed further at the Coast to Coast Conference in Melbourne in 2006 and it was agreed that Bruce Thom develop a constitution of a company limited by guarantee that would operate on a national basis.

This plan was accomplished and in 2008 at the Coast to Coast Conference in Darwin the constitution was ratified and an Executive appointed. The company received charitable status in 2011.
