Abstract:
The tourism activities of Sri Lanka mainly have concentrated in the areas of around
Colombo as a commercial hub, along the selected beaches of the west, southwest and eastern coasts, in
Central Highlands, and the historic and religious heritage of the Cultural Triangle. All these activities
cover the main island of Sri Lanka. Even though, a considerable amount of small islands is situated in
our coastal waters, they have neglected in tourism development perspective. Many islands of Sri Lanka,
especially in the Gulf of Mannar, Dutch Bay and Puttalam lagoon can develop using the Polymotu
concept (poly=many, motu=island), which is to use the geographical isolation of dedicated sites for
conservation and reproduction of individual varieties of plants, trees, animals (wildlife) and even limited
tourist resorts. Similarly, weathered bedrock islands also can develop as bird sanctuaries, religious and
scenic attractive places for ecotourism, and also geotourism, cultural tourism. Also, the study of islands
of Sri Lanka will be very helpful for fishermen, sailors who use the nearshore and offshore, students of
different educational institutions, researchers and the other scientists. As postulate, if sea level rise occur
by 2100, about 1.0 or 1.2 metre or more in surrounding Sri Lankan waters, many of the northern islands
will be subjected to erode and submerge frequently
