Over 10 km of beach stretches, spread over 19 beaches, in Goa face the threat of erosion, Water Resources Minister Vinod Palienkar said on Tuesday.

Sea erosion and beach protection measures were being taken in popular beaches like Anjuna, Keri-Tiracol, Morjim in North Goa and Agonda, Betalbatim, Majorda, etc.

According to the details Palienkar listed in his written reply, the most affected beaches are Betalbatim (1,320 metres), Arossim (1,190 m), Agonda (1,000 m), Keri-Tiracol (1,000 m).

Palienkar said that sea erosion affected over 10.39 km of the coastline that attracts more than six million tourists every year.

The Minister said that measures like building protection walls, reinforcing erosion-affected areas with tetra-pods and geo-fibre barriers were being taken to salvage the beach stretches.
