On 27 March 1990, Palawan was inscribed as a Biosphere Reserve (BR) under the United Nations, Educational, Scientific and Cultural Organization (UNESCO)- Man and the Biosphere Programme (MAB). After almost three decades, the MAB Advisory Committee during its 29th Session on 12-15 June 2017 at the UNESCO Headquarters in Paris officially recognized that Palawan BR met the criteria of the Statutory Framework of the World Network of Biosphere Reserves, and likewise satisfactorily fulfilled the three complementary functions namely: (1) conservation function, to preserve genetic resources, species, ecosystems, and landscapes, (2) development function, to foster economic and human development, and (3) logistic support function, to support demonstration projects, environmental education and training, and research and monitoring related to local, national and global issues of conservation and sustainable development. In almost four decades of Palawan’s recognition by the world body, it has continuously served as a model BR not only in the country but for the rest of the world.
