ecological service. They have been defined as a transparent system for the additional provision of environmental services through conditional payments to voluntary providers (Tacconi, 2012). With most of the water sheds and other viable hydrological sources of the country under the governance of the indigenous communities, systems to recognize and pay for the eco- system services provided by the IPs in managing and maintaining the resources should be institutionalized. This shall not only give longoverdue justice to the IPs but enable them to secure a stable source of revenues that shall address their socio-economic needs as well as defray the costs of protecting the natural resource and sustain it for future generations. n Case Study THE ANCESTRAL DOMAIN OF THE TAGBANUA OF CORON ISLAND AND THE LOCAL TOURISM he Calamian Tagbanua inhabit the beautiful T limestone island of Coron, one of the Calamianes islands of North Palawan. They consider themselves the caretakers of their Teeb Ang Suriblayen (ancestral domain), tasked to maintain the richness and diversity of Earth life for the welfare of present and future generations. This holistic self-concept of ecological stewardship is at the heart of the Tagbanua’s traditional resource management and their determination to fight for self-management and tenurial rights over their ancestral domain. By the mid-1980s the marine resources surrounding the island were being degraded at an alarming rate by dynamite, cyanide, and other illegal and destructive fishing methods. The situation was so serious that the Tagbanua began facing food shortages. Worse, the sacred clan caves where they harvest with care the edible bird’s nest were leased out to non-Tagbanua entrepreneurs by the municipal government. Powerful politicians and businessmen are planning to take over the island for tourism development. In response to these ecological assaults, they sought ways to secure their land and resource rights with the timeline presented below. Major Gains from the Awarding of the CADT With the issuance of the Certificate of Ancestral Domain Certificate (CADC) in 1998 and the consequent awarding of a Certificate of Ancestral Domain Title 108 (CADT)   in 2002, the Tagbanua have since been able to achieve major gains: • They were able to convince the government to recognize the local traditional leadership as an “Interim Protected Area Management Board”. The local government also respected and recognized their Ancestral Domain Management Plan, which provides guidelines for the utilization and management of the land and seas and the conservation of the natural resources within the island.
