ECONOMIC VALUATION OF MANGROVES IN TAWI-TAWI ISLANDS, SOUTHERN PHILIPPINES: A MARKET PRICE AND CONTINGENT VALUATION APPROACH
Creators
Description
This study focused on the economic valuation of mangroves in the
province of Tawi-Tawi in Southern Philippines. Mangroves are recognized
as a provider of a variety of products and essential ecosystem services that
contribute significantly to the livelihood of local communities. However,
mangroves forests in the area are being neglected as an important
ecological function and service apart from providing goods to the
communities. Mangroves are being harvested with not as much knowledge
on how to protect, restore and conserve for the future’s well-being. The
study calculates the economic value of mangroves present in the area
through estimation of Total Economic Value (TEV) using market price and
contingent valuation method technique. The TEV will help identify and
quantify the contribution of mangrove ecosystem services to the population
in the Tawi-Tawi Islands. The study used Willingness to Pay (WTP) to
calculate the Non-Use Value (NUV), specifically, Bequest Value to gather
the people’s willingness to pay for a hypothetical proposed project that will help conserve, preserve and protect the mangroves in their area using
climate change scenario. The Total Economic Value (TEV) of mangroves in
Tawi-Tawi are computed using local market price surveyed from the 50
respondents who are directly linked to the livelihoods of the mangrove forest
system. Here, the estimated Total Economic Value (TEV) of mangrove
benefit was identified. Market prices, replacement costs, benefits transfer
value, and cost-benefit analyses have been used for value determination
and comparison. The results showed that the TEV per year of mangroves
in Tawi-Tawi, Philippines is ranging from 36,255,856 USD/year to
53,353,223 USD/year or 3,216 USD/year per hectare to 4,733 USD/year
per hectare. The highest value contribution derived from the indirect use
value (89.92%), whereas willingness to pay (WTP) results showed that high
level of WTP at PHP 992 or 19.84 USD per household which indicates that
the communities are willing to make spending for the proposed project to
protect the mangroves in their area. Nonetheless, with the number of
respondents who are unwilling to pay, efforts should be carefully considered
to promote sustainable projects which can benefit the local people as well
as the mangrove forest system. The local government unit should reflect
into local awareness about climate change issues, whereas, the importance
of mangroves should be enhanced to get the local communities involved in
mangrove conservation and protection increase knowledge and trust at the
household level. Finally, further research to explore the socio-demographic
roles of the mangroves in the area to the local communities is
recommended.
