      Biosphere Reserve Information

Viet Nam


  General Description   The Red River Delta Biosphere Reserve lies in northern Viet Nam, at the coastal-sea interface. It contains one of the main remaining large tracts of mangrove forest in Viet Nam, with some 30 species of mangrove. These wetlands have a high biodiversity, especially at the Xuan Thuy Ramsar site (12,000 ha) and in Tien Hai district, which are sites for breeding/stop-over along the East-Asian or the Australian flyways. Eleven bird species denoted either by IUCN as “threatened” or by Birdlife International as “near threatened” have been recorded from the Red River Delta. The rare dugong (Dugong dugon) is present here. The climate is tropical monsoon. The two core areas located in the Giao Thuy and Tien Hai districts (one of which contains the Ramsar site) are protected as nature reserves and each is surrounded by a set of buffer zones and transition areas. These two parts are connected by a corridor. Over 128,000 people live in the Biosphere Reserve, mainly in the transition area. Typically, each village forms a close “clan” with a rich cultural heritage which helps bond the communities and sustains social development. The Biosphere Reserve promotes the wise use of water for domestic use, irrigation (rice farming, etc.), livestock watering, transportation (connection between up-land, delta and maritime transport, etc.), and fisheries (freshwater and coastal fisheries). This site has been relatively well researched (e.g. the SARCS/WOTRO/LOICZ Core Research Project on ' Economic Evaluation of Mangrove Rehabilitation and Restoration in Nam Ha Province, Red River Delta' 1996-1999, 2000 – 2004 and the Viet Nam-Holland Research Cooperation: Red River Delta Research Program, 1999 –2004). There are some 75 permanent research workers, of which a third are from outside Viet Nam. The site is actively used by all levels of students. The UNDP-GEF Project on the Conservation of Coastal Wetlands in the Red River Delta, Viet Nam (VIE/00/G42/A/1G/99) strongly endorsed the nomination of this site as a biosphere reserve in 2004.
A coordination board of the biosphere reserve is formed by members from the individual protected areas of the districts. Its activities are based current plans of each district’s management board, internationally and nationally on-going multilateral and bilateral projects, as well as the National Action Plan for implementing the CBD of Viet Nam.
