Due to climate change the Sundarbans faces several challenges. With rising sea levels, islands are disappearing and the increasing salinity in the water and soil has severely threatened the health of mangrove forests and the quality of soil and crops.
How global warming affects Sundarbans?
Global warming and climate change compounds the dangers to the Sundarbans. These low-lying mangrove forests are highly susceptible to the effects of sea-level rise-including inundation of coastal areas, increased exposure to storm surges, increased coastal erosion, and rising salinity in ground and surface waters.
