The National System of Protected Areas (Spanish: Sistema Nacional de Áreas Protegidas) (SINAP) is the Colombian national park administrator. It is a department under the Ministry of the Environment, Housing and Regional Development responsible for the conservation and sustainable use of biological diversity. SINAP was established after Colombia signed the Convention on Biological Diversity through Law 165 of 1994, and has been the primary activity of the Colombian Government regarding the conservation of biodiversity. The areas of the Park System supply 25 million people with water.
