Tourism carrying capacity using GIS-based mapping of ecotourism sites in Tablas Island, Romblon, Philippines

Many areas in the Philippines are identified as potential ecotourism sites. For sustainable tourism development or site management, a carrying capacity analysis can ensure low and manageable environmental impacts, accommodate a high level of visitor satisfaction, and give stakeholders and local communities adequate economic returns. This study’s findings describe the carrying capacity of ecotourism attractions in Tablas Island, Romblon. It used a descriptive mixed method of research with 63 respondents selected using purposive and quota sampling techniques, and a GIS map was constructed to illustrate the physical geography and fundamental attributes needed to estimate the capability of the sites. The venues’ carrying capacity estimate was computed using Boullon’s Tourism Carrying Capacity Model. The results revealed respondents’ standard visitor requirements ranged from 1.43 m2 to 2.14 m2 to 2.86 m2. Most of them only required 1-2 hours but some needed as much as 4-5 hours to really enjoy their activities. The sites’ determined tourism carrying capacity is 1,157 visitors/day for Dubduban Falls in San Agustin; 612 visitors/day for Mablaran Falls in San Andres; and 138 visitors/day for Tuburan Falls in Odiongan. These results can be used to improve tourism site development in Tablas Island, Romblon.
