Case study- Odisha+ the sundarbans Flashcards
what are the sundarbans
coastal zone occupying the worlds largest delta, which is formed from the sediment deposited by the Ganges and other rivers
-Mangrove forests and swamps
-delicate equilibrium of natural processes
-provides resources, fuel wood
what are the natural challenges in the sundarbans
-coastal flooding
-cyclones
-high salinity levels in the soil
-human eating tigers
what are the human challenges in the sundarbans
-over exploitation of resources
-conversion of wetlands to other use
-destructive fishing
how much mangrove forest land is there in Odisha
1435km squared
why are mangrove forests good
shelter against storms and floods
-one hectare = $12,000
what parts of Odisha are doing what
-46.8% accreting(deposition), in the north
-36.8% eroding in the south
-14.4% stable
where is Odisha
coastline on the Indian coast, Bay of Bengal close to bangladesh+ river Ganges
is there significant erosion or deposition in Odisha
deposition
why is there erosion in the south of Odisha
Groynes in the center causes no sediment to be in the south ->no protection
how do we know if the SMP worked/ was successful
Odisha cyclone (1999) - 10,000 people died
-similar cyclone in 2013 (Phailan) only killed 44 people- defences, warning systems and mitigating strategies e.g. planting mangroves (CHEAP)
in 1909, villages with a mangrove width of 4km+ reported no deaths during cyclone kalina, but any with less reported many deaths
what are the human oppurtunities in Odisha
tourism, fish, wind farm potential
