case study- The Sundarbans Bangladesh - Coggle Diagram
case study- The Sundarbans Bangladesh
background
mangroves and swamps
worlds largest delta- 10,000 km^2 sediment from The Ganges, Brahmaputra and Meghna
climate change
adaptations
challenges
flood waters remain for longer
increased frequency and intensity of floods
water levels rise as there is more silt
rising temperatures increase salinity in soil
increased use of pesticides
changes to rainfall patterns
challenges to The Sundarbans
natural
cyclones
high levels of salinity in the soil
coastal flooding
accessibility and remoteness
instability of the islands
human eating tigers
human
conversion of wetlands to intensive agriculture and settlements
destructive fishing techniques
over-exploitation of resources
lack of awareness on environmental importance of the region
resource- use conflicts
coastal processes
monsoon winds create sand dunes which are then built up with silt to create islands with vegetation and mangroves
the coast should grow due to this process
tidal action shapes the landscape- land is drained due to tides
human response to the challenges
protection of open access areas
one hectare of mangrove forest has an economic value of $12,000
raised cyclone shelters
mangroves offer protection against erosion and floods
