This study, largely completed in 2008, examines the implications of redefining the Philippines' baselines, maritime boundaries, and jurisdictional areas on the country's security interests and on its diplomacy and foreign relations. Its primary goal, in tandem with its partner studies on living and non-living resources and on navigation, is to help develop a strategic and integrative framework for policy formulation, review, and evaluation that policymakers and government bodies may utilize in addressing the country's territorial and maritime jurisdictional concerns.
