|Biosphere Reserve Information|
The Mananara-Nord Biosphere Reserve is located on the north-east coast of the island and covers an area of 140,000 hectares. Madagascar has an extremely rich biodiversity with more than 85 percent of its species being endemic. That is why the conservation of its natural environment is considered not only a national but an international priority. The ecosystems in the biosphere reserve are very diverse and include tropical humid forest, sandy coastal plains with littoral vegetation, river vegetation, mangrove formations, marshlands, and coral reefs.
The biosphere reserve has gained international recognition as a pilot project that merges nature conservation, buffer zone development and participation of local communities in management activities. Approximately 47,000 inhabitants live in the area (1995). Participatory research has been carried out to identify the needs of local people (increased rice production and yields, diversification into small-scale stock rearing, improved health care aimed at decreasing mortality from malaria, diarrhea diseases and bilharzia, and financial support for education). In the light of these identified needs, the project operations have targeted native villages of tavystes (highland rice cultivators) and fishermen around the national parks, with operations in sectors such as agriculture, rural infrastructure, health, education, fishing, animal husbandry, women's organizations, research, conservation and adventure tourism.
A special effort has been made to reduce forest clearance linked to the shifting cultivation method of growing rice. With the co-operation of local farmers, a series of small dams and waterworks were constructed to irrigate intensively managed rice fields. Since rice yields doubled, this system directly benefited 465 families and contributed to forest conservation. The University of Tananarive provides the main scientific backing for the work at Mananara-Nord.
