Both issues - soil erosion and contamination of ground water - have been major concerns for the coastal state which banks heavily on tourism for revenue.

According to data presented in the state legislative assembly during the recent monsoon session, more than 10 per cent of the state's beaches have already been eroded due to global warming and the consequent rise in sea water levels.

Goa's most popular beach stretch from Calangute to Candolim has already seen massive erosion thanks to the presence of cargo ship MV River Princess, which had beached at the shore nearly a decade ago.
