Dr Berkes approaches traditional ecological knowledge as a knowledge-practice-belief complex. This complex considers four interrelated levels: local knowledge (species specific); resource management systems (integrating local knowledge with practice); social institutions (rules and codes of behavior); and world view (religion, ethics, and broadly defined belief systems). Divided into three parts that deal with concepts, practice, and issues, respectively, the book first discusses the emergence of the field, its intellectual roots and global significance. Substantive material is then included on how traditional ecological (...) and management systems actually work. At the same time it explores a diversity of relationships that different groups have developed with their environment, using extensive case studies from research conducted with the Cree Indians of James Bay, in the eastern subarctic of North America. The final section examines traditional knowledge as a challenge to the positivist-reductionist paradigm in Western science, and concludes with a discussion of the potential of traditional ecological knowledge to inject a measure of ethics into the science of ecology and resource management.
