ALTO ORINOCO-CASIQUIARE

 
       
  General Description   The Alto Orinoco - Casiquiare Biosphere Reserve is located in the Venezuela Amazon. The altitude ranges from zero mainly in the lowland in the plateaux of Casiquiare Canal, up to 3,000 meters above sea level in the northeastern region (Cerro Marahuaca). It contains tropical rainforest with Ombrofilis wood. The biosphere reserve has a population of approximately 150,000 inhabitants (1991), of which less than 10% constitutes indigenous groups. The primary aim of the biosphere reserve (which was created in 1992) is to secure the ancestral homelands and traditional lifestyles of Yanomami and Ye’kwana indigenous peoples. Challenges and problems include the opposition of some local residents towards protected areas and the prohibition of mining and logging activities, the lack of effective mechanisms and technical experience for conservation and development programmes, the need for a culturally sensitive and practicable management plan for the region, and incursion into the region of illegal gold miners. The Centre for Environmental studies of the Main University of Venezuela with the Department of Territorial Economical and Social Analysis develop a model for territorial management in the “Upper Orinoco” region, able to ensure the protection and sustainable use of the environment. Education activities, technical assistance and research, and recognition of local and cultural practices are also being developed.
