Descripción
In developing and implementing forest land use plans to attain sustainable forest governance, it is necessary to determine and value priority ecosystem services derived by society from forest and watershed ecosystems. This study aimed at estimating the value of four ecosystem services in a forest management project site in Nueva Vizcaya and Quirino provinces, Philippines: provision of water services, soil erosion control, carbon storage and sequestration capacity, and biodiversity conservation. The Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) tool was used to value water provision services (using a cost-based approach), soil erosion control (using replacement cost method), and carbon storage and sequestration capacity (using social cost of carbon). Contingent valuation method was used to determine the willingness to pay for biodiversity conservation. BAU and Development scenarios were used in determining changes in forest and other land uses in the site as well as estimating the value of the ecosystem services. Results show increases in forestland area and amounts of carbon storage and sequestration, decreasing annual water yield due to projected declining rainfall amount, and decrease in total annual soil loss. Mean WTP is PhP170 (~ US$ 3.50)/household/year. The estimated values of the four ecosystem services provide baseline information for local governments in crafting payment for ecosystem services strategies to help fund forest conservation.Keywords: policies, financial mechanisms, sustainable forest management, governanceID: 3486628
