Probably more than any other British anthropologist, Roy Ellen is associated with the study of ethnobiology; his has also long ranked among the leading names in the field . . . Both readers new to Ellen as well as those already familiar with his work will find this collection rewarding. American Anthropologist The 1990s have seen a growing interest in the role of local ecological knowledge in the context of sustainable development, and particularly in providing a set of responses to which populations may resort in times of political, economic and environmental instability. The period 1996-2003 in island southeast Asia represents a critical test case for understanding how this might work. The key issues to be explored in this book will be the creation, erosion and transmission of ecological knowledge, and hybridization between traditional and scientifically based knowledge, amongst populations facing environmental stress (e.g. 1997 El Niño), political conflict and economic hazards. The book will also evaluate positive examples of how traditional knowledge has enabled local populations to cope with these kinds of insecurity.
