Marine ecosystems are main tourist attraction in Sri Lanka and globally. Due to the public good
nature of the resource, they are subjected to much free riding and hence degradation. Economic
values, their estimation and appropriations is considered a much felt need in proper
conservation and management of these resources. Objective of this study is therefore to review
the available literature on economic valuation of marine recreational areas and to explore the
gaps in the local and global contexts. Available literature were searched using the keywords
marine recreation valuation and using search engines such as Science direct and Google scholar
together with individual journals dedicated to marine valuation. The values were then converted
to a common currency (US$) and 2018 prices using GDP deflator values for comparison.
According to the results, a range of valuation methods have been employed in marine
ecosystem valuation and contingent valuation method, travel cost method and choice
experiment method were among the most common. Many researches have estimated
recreational values including both local and global values. The concepts of total economic value
and the ecosystem service framework have been commonly used in the studies. Valuation focus
was wide ranging including economic value of ecosystem services in the coastal regions, value
of wetlands in supporting recreational fishing, benefits of coral ecosystems, indirect and
existence value of coastal and marine biodiversity, recreation value of coastal lagoons and
values of beach erosion control. Estimated values range from US$ 9.24 to US$ 31.63 billion for
the selected studies. These studies have been carried out in U.S, Brazil, Hawai, Maldives, India,
China, Portugal Tunisia and Sri Lanka. Value of Ecosystem Services has been carried out in Sri
Lanka for Bar Reef Marine Sanctuary and Pigeon Island National Park and recreational values
have been estimated for Hikkaduwa Marine Sanctuary. It was found that the use of values in the
policy context has been very limited in the developing country context and the signal provided
for the policy makers about the importance of these recreational resources has not been properly
recognized. Further this study emphasizes the research gaps in the world especially in the Asian
region and Sri Lanka and the need to develop interdisciplinary studies that contribute to our
understanding of the complex oceanographic, ecological, and economic factors that are
involved in the governance, use, and stewardship of marine ecosystems. |
