Impact of climate change on vulnerable populations in Bangladesh
Cyclones and Flooding
Destruction of villages
Forced migration
people living on cities has doubled
Ponds and canals have been concreted over with no regard for natural drainage
Monsoon rainbursts frequently submerge streets in knee-high water.
population in southwestern coastal regions is stagnating
displaced people cross borders
regional and international concern
20 million Bangladeshis are living illegally in India
Cross by boat across the rivers to avoid patrols
Buildings flattened
Access to clean water limited
Tropical cyclones are expected to get more intense and destructive with global warming
Raise the risk of another devastating storm surge.
Adaptation
three-storey cyclone shelter
Farmers
adapted to fattening shrimp
crab (tolerate high salinity) strong demand in China and Malaysia
no rice crops
Fields too salty for agriculture
Levee
supposed to protect Gabura
liability when the floodwater got in and could not get out again
UN
first meeting in May
work plan grapples with patchy data and institutional clashes
Climate migrant status
no ready source of financial support
no protection status under international law if they cross borders
not easy to distinguish from economic migrants
moving to Malaysia, India, Pakistan and the Middle East
Sea level rise
validity of information
rough assumption
official in the environment department could not state source
US-based science outreach organisation, paints a less dramatic picture
increasing salt intrusion into groundwater
turn 30 million people into “climate migrants”
submerge 1/5 of the country
one-metre rise in sea level
2C temperature rise is consistent with 4.7m of sea level rise.
