    Abstract
    Coastal tourism is typically accompanied by developments along the coast - on sand dunes, cliffs, promontories, and sandy beaches - with possible implications for coastal processes and, eventually, for human activity located on the coast. National coastal zoning policies, designed as appropriate safeguards, are in place but often not enforced strictly. Noticeable changes in coastal landforms are observed in the study area, mainly in the tourist belt between Sinquerim and Fort Chapora in Goa, India. Exceptions are certain pockets where tourism activity was on a smaller scale. The headland at Baga was almost uninhabited in the 1970s and 1980s. It is now covered with concrete structures and its tidal creek is being reclaimed at a swift pace. There a was thriving salt pan industry in the southern part of the Baga stream in the 1960s and 1970s, which has been reclaimed in a very haphazard manner for constructing tourist accommodations, road networks, and amusement parks. This has resulted in the obstruction of free tidal flow and the creation of water pools, promoting algal growth. Towards the south, the course of the Nerul river has actually shifted southward since 1965. Ascertaining the cause for this would require detailed studies. The width of Sinquerim to the Baga beach stretch is getting narrowed and flattened, as sand dunes are razed and built-up structures creep closer to the shoreline. Sandy spaces are giving way to cemented parking lots and dune vegetation is being destroyed recklessly. Tourism-related development is indeed taking a heavy toll of the natural beach ecosystems by destroying sandy space, diminishing dune vegetation, and reclaiming land. Alternate erosion/accretion phenomena are noticed all along the shoreline. Further studies are needed, however, to investigate the relative contributions of natural and/or anthropogenic causes to the observed changes
