Abstract/ Executive Summary:

Assessment of hazard characteristics, exposure, vulnerability, resilience and risk at a local scale is an important tool for identifying the capacities of households and local communities to adapt with climate change induced flood. Repeated floods with different magnitudes under variable climatic conditions are great catastrophe for the people living in flood prone regions specifically in Islands. People, infrastructure and economy are highly exposed to flood and that results in devastating flood disaster. In the Padma river Islands frequent flooding makes the life and livelihoods of people vulnerable and this vulnerability is conditioned by different factors such as people’s physical, social, economic and environmental condition. The higher is the level of vulnerability the higher is the level of flood risk. Hence, people’s resilience can minimize the negative impacts of flood disaster. A composite risk index (related to the probability of occurrence of the event, magnitude of the event, quantity and cost of the element at risk, vulnerability and resilience) was prepared to realize the climate change induced flood disaster risk. Some adaptive strategies are explored to adapt with climate change induced flood risk. Finally, Local Scale Disaster Risk Model (LSDR) was proposed to present the framework of climate change induced flood disaster risk and adaption at a local scale.

Objectives:

Climate change induced flood produce widespread damage and several alterations in the normal functioning of communities. The study was under taken to identify the climate change and its impact on flood situation.

Methodology:

The paper mainly review the following conditions- Conceptual Framework for a Local Scale Risk Indicator System; Preparation for Local Scale Risk Index; Rainfall and Flood Events; Exposure; Assessing Vulnerability and Resilience; The Risk Index; Adaptation Strategies and Local Scale Disaster Risk (LSDR) Model.

Achievement/Findings:

This study finds that climate change induced flood risk is the combination of hazard, exposure, vulnerability and resilience. The higher the level of resilience the lower is the level of risk and the higher the level of hazard, exposure and vulnerability the higher is the level of risk. The flood problem in the Gangetic char land is closely associated with the rising monsoon rainfall, people and element at risk, physical vulnerability, social vulnerability, economic vulnerability, environmental vulnerability, physical and environmental resilience, social resilience, economic resilience, institutional resilience and community coping mechanism.
