Contingent Valuation, Mangrove Forest Restoration, Willingness to Pay (WTP)Abstract
Purpose: This study aimed to determine the economic value that residents of Ipil, Zamboanga Sibugay, Philippines, place on the restoration and conservation of mangrove forests.
Methodology: A quantitative research design employing the contingent valuation method (CVM) was utilized. A survey was conducted with 388 residents to assess their willingness to pay (WTP) for mangrove conservation. Two funding mechanisms were examined: dedicated taxes and price increases on goods/services, each with varying bid amounts (Php 32, Php 64, and Php 8).
Findings: The study found that 70.4% of the residents were willing to pay for mangrove conservation. Dedicated taxes, specifically at a bid amount of Php 32, were the preferred funding mechanism. Socioeconomic factors, such as income and livelihood dependence on mangroves, significantly influenced WTP.
Unique Contribution to Theory, Practice and Policy (Recommendations): The government should implement dedicated taxes as a primary funding mechanism for mangrove conservation in Ipil, Develop targeted conservation programs focusing on residents with higher incomes and those whose livelihoods depend on mangroves. In addition, it should conduct community engagement programs to raise awareness and understanding of the ecological and economic importance of mangroves. Further research is needed to investigate the factors that did not significantly influence WTP (education level, coastal proximity, residency duration, and environmental awareness) to gain a more comprehensive understanding of resident attitudes and behaviors.
