The National Integrated Protected Areas System (NIPAS) Act of 1992 establishes a legal framework for the management of protected areas in the Philippines, aiming to conserve biodiversity and ensure sustainable resource use. The Expanded NIPAS Act of 2018 enhances this framework by including additional protected areas and addressing the complex overlap with indigenous peoples' ancestral domains. These acts emphasize the need for cooperation between national and local governments and stakeholders to effectively protect the country's natural resources.
