Investor Presentaiton
Current Climate Adaptation Deficit
*
Beyond improvements in drainage infrastructure
already planned and proposed, additional
structural measures (pumps, sluice gates,
storm-water pipes) will be necessary to mitigate
waterlogging even without climate change.
From the hydrological modeling simulations, the
study recommended a list of investment options
for each study area to reduce inundation depth
to 4-8 inches within 12 hours.
The cost of mitigating Dhaka's waterlogging
even without climate change would cost Tk. 2.7
billion.
NOTE: Tk 2.7 billion is equivalent to only
0.35% of the govt's development budget in
2014-2015.
Climate Change Impacts
Rainfall in Ganga-Brahmaputra-Meghna basin
is expected to be more erratic with climate
change.
More intense rainfall is expected in the coming
decades.
Intense rainfall events are expected to be more
frequent.
Climate Change Rainfall is approximated by 16
percent increase in 24-hour rainfall in Dhaka in
2050 as compared to the baseline.
Adaptation to climate change would require an
additional investment of Tk 1.3 billion.
