Abstract

The uplands in Nagcarlan, Laguna is a natural resource that benefits the town as a watershed, a land for producing food crops, and as a carbon sink. The combined effects of economic development, population growth, and mismanagement of the uplands can put this resource at risk. Determining the value of the ecosystem services that are provided by the Nagcarlan uplands can be a useful information in designing a sustainable framework to effectively manage this natural resource. This study was conducted to estimate the economic value of selected ecosystem services provided by the Nagcarlan uplands and to determine how land use changes can affect these values. The study focused on use values of ecosystem services, namely, food provisioning, water supply, and CO2 regulation. The land use changes that were analyzed were: 1) expansion of the area planted to vegetables, and 2) conversion of the agroforest in the protected area into a dipterocarp forest. Converting the agroforest into a dipterocarp forest was found to be a more ecologically sustainable option. The carbon market through the Clean Development Mechanism can be used to provide farmers an incentive to assist the government in natural resource management.
