KOLKATA, India (Reuters) - Rising sea levels are causing salt water to flow into India's biggest river, threatening its ecosystem and turning vast farmlands barren in the country's east, a climate change expert warned Monday. A study by an east Indian university in the city of Kolkata revealed surprising growth of mangroves on the Ganges river, said Pranabes Sanyal, the eastern India representative of the National Coastal Zone Management Authority (NCZMA).

A study by an east Indian university in the city of Kolkata revealed surprising growth of mangroves on the Ganges river, said Pranabes Sanyal, the eastern India representative of the National Coastal Zone Management Authority (NCZMA).
"This phenomenon is called extension of salt wedge and it will salinate the groundwater of Kolkata and turn agricultural lands barren in adjoining rural belts," said Sanyal, an expert in global warming.

Sea levels in some parts of the Bay of Bengal were rising at 3.14 mm annually against a global average of 2 mm, threatening the low-lying areas of eastern India.
Climate experts warned last year that as temperatures rise, the Indian subcontinent -- home to about one-sixth of humanity -- will be badly hit with more frequent and more severe natural disasters such as floods and storms and more disease and hunger.
