Outline of the Discussion
What are the major consequences?
Why Bangladesh is Vulnerable to CC?
Climate Change (CC) Stressors and their Impacts on BD
Challenges for the vulnerable community
Challenges from CC Perspective
■ Socio-economic and Physical Dimension
Immediate Response

Consequences of CC
� Temperature Rise
– Land Surface Temperature
– Sea Surface Temperature
� Variation in Precipitation
� Sea Level Rise
Majority of the impacts of climate change can be reflected in water. This is:
a. Too much waterb. Too little waterc. Wrong type of waterd. Wrong timing of water

Changes in Means
Changes Potential Impacts
Increase in temperature Reduction of crop yield
Scarcity of water/Drought
Human health, LS, Poultry
Variation in precipitation Increase risk of flooding
Increase risk of water logging
Increase risk of landslide
Increase risk of in-migration due to river bank erosion
SLR Salinity intrusion, Inundation

Changes in ExtremesChanges Potential Impacts
Flood Damage to households in slum and squatter areas
Damage to roads and other infrastructures
Damage to utility services
Spread out of water borne diseases
Drought Severe water scarcity
Heat or cold waves
Short term changes in energy demand
Health stress due to extra heat or cold
Tornado Damage to households in slum and squatter areas

WHY BANGLADESH IS VULNERABLE??
The Bengal Delta is the product of complex hydrological and sedimentation processes of the Ganges-Brahmaputra-Meghna
(GBM) river systems
