This study explicated the different issues and opportunities for conservation, and sustainable development, specifically for Samar Island Natural Park (SINP), Philippines. Specifically, the study also determines the associations of different efforts mandated and implemented by different government agencies both from the national and local, assessing the impacts and effects of current and potential plans and programs for conserving and sustaining SINP as a future UNESCO WHS and to conceptualized a framework that would highlight the basic factors on place branding development based on the case of SINP.

Participants from the FGD were representatives from different government agencies from the national, regional, local, and people’s organizations. The gathered information was analyzed through a repertory grid.
