Biosphere reserves are areas comprising terrestrial, marine and coastal ecosystems. The biosphere reserve title is handed over by UNESCO. Each reserve promotes solutions reconciling the conservation of biodiversity with its sustainable use. Biosphere reserves are ‘Science for Sustainability support sites’ – special places for testing interdisciplinary approaches to understanding and managing changes and interactions between social and ecological systems, including conflict prevention and management of biodiversity. Biosphere reserves are nominated by national governments and remain under the sovereign jurisdiction of the states where they are located. Their status is internationally recognized.
The Philippines currently has three UNESCO Biosphere Reserves. The first Biosphere of the country was designated in 1977.
The Palawan Biosphere Reserve is the only biosphere reserve in the country that contains a Ramsar Wetland Site (Tubbataha Reefs Natural Park) and two UNESCO World Heritage Sites (Tubbataha Reefs National Park and the Puerto Princesa Subterranean River National Park)
The Philippines became a committee member of the Man and Biosphere Programme of UNESCO in 2016 and shall retain the position until 2019.
Ecological frontiers like Eastern Mindanao, Eastern Visayas, Sibuyan island, Western Panay, the Sierra Madre, Southern Mindanao, the Sulu Archipelago, and the Cordilleras are theoretically capable of standing as UNESCO Biosphere Reserves in the future, along with specific Key Biodiversity Areas (KBAs) designated by Haribon Foundation and the Department of Environment and Natural Resources (Philippines). In comparison to the 3 biosphere reserve of the Philippines, Indonesia has 11 biosphere reserves, China has 33, India has 10, Iran has 11, Japan has 9, Kazakhstan has 8, South Korea has 5, Sri Lanka has 4, and Vietnam has 9. The Philippines is one of the 18 ecological hotpot countries of the world, containing more than 228 Key Biodiversity Areas (KBAs).
