The undivided Sundarbans was politically
divided during partition and independence of India (15 August
1947) in to two parts. The larger part (about 60%) falls to
Bangladesh (then East Pakistan) and rest falls to India. The
Indian Sundarbans are located between 21032'-22040' north
and between 88085'-89000' east within the 24 Parganas district
of the state of West Bengal. The 24 Parganas district was
divided into North and South 24 parganas in 1986. The larger
part of Indian Sundarbans was included into South 24 parganas.
The Sundarbans region comprises of 19 Development blocks (13
under South 24 parganas and six under North 24 parganas) and
a reserve forest (including Wildlife sanctuaries and Tiger
reserve). The whole area is declared as Biosphere Reserve.
The region is bounded by the river Hooghly
to the west, the Bay of Bengal to the south, the Harinbhangha
-Raimangal river along international boundary with Bangladesh
to the east and the Dampire- Hodges line to the north.
