Substantially resourceful and densely populated Sundarbans delta, covering
India and Bangladesh, experiences numerous extreme events linked to various
hydro-meteorological processes. Further, anthropogenic activities in the coastal zones
are accentuating environmental degradation causing wide spread suffering. While
large tracts of the Sundarbans were cleared, drained and reclaimed for cultivation
during the British colonial era, the remaining parts have been under various protection
regimes since 1970s to protect the various flora and fauna. Spatio-temporal study using
satellite remote sensing showed, while the mangroves’ areal extent has not changed
much in the recent past, accretion rate of coastline has declined as against erosion rate
which has remained relatively high in the recent years. As a result, the delta front has
undergone a net erosion of ~170 km2 of coastal land during 1973–2010. Thus, the
various factors affecting such changes are direct human interference, upstream development
in the river hydrology, climate change, extreme weather events including
cyclones, tidal surges, floods, sea level rise, salinity intrusion, etc. acting individually
or through their interactions. Impact of such factors on agriculture and aquaculture
being the main components towards livelihood security has been discussed. There is a
need for integration of traditional coping practices and wisdoms with modern scientific
management approach in this eco-region to reduce the effects of climate change- and
other natural or human factor-induced disasters, and arrest nature and extent of human
sufferings for improvement of livelihood enterprises, agriculture and aquaculture
being the most important.
