Abstract

Mangrove is a wetland type of forest referred also as the tidally influenced swamp ecosystem within intertidal zone of tropical and subtropical latitudes (Tomlinson, 1986). This forest provides numerous direct and indirect benefits to people and environment. However, most of the benefits appreciated are focused on direct-use or marketed benefits making mangrove forests as undervalued resources today. This study aimed to asses the Indirect-use and Option Values of mangroves in Barangay Day-asan, Surigao City as components of forest economic valuation. The Replacement Cost and Contingent Valuation Methods were used in value determination. Survey showed that as to socio-demographic profile of the participants, there is a total of 451 households in Barangay Day-asan. Most of the participants were female (68.89%), married (34.07%) and attained secondary level of education (42.22%). Fishing is the very source of income among the local residents. The total Indirect-use value of mangrove forest of the study area is approximated at Php6239.15/hectare/per year valuated by means of Coastal Protection and Carbon Sequestration Values. The study revealed that mangrove forests in this coastal community provide considerable economic and environmental benefits, particularly as a source of family income, provision of quality air to breath and in protecting local communities from disasters associated with the climate change. Most of the residents agree to take part in mangrove conservation programs and initiatives with an average Willingness To Pay of Php594,115.20 per year as conservation funds for the sustainable management of the mangrove resources in their community.
