The papers in this book were first presented at the Association for Environmental Archaeology conference at Newcastle upon Tyne in 1998. The aim of the conference was to encourage contributors to examine the inter-relationships between classes of data that have increasingly come to be treated in isolation and to encourage thinking about theory in environmental archaeology. Authors have focused on explicit development of theory, others on bridging barriers between different fields of study or classes of evidence. The notion that people are influenced, but not necessarily determined, by the environments in which they live, may seem like a truism, but an ecodynamic perspective however requires us to question the human impact on the environment, disregarding agricultural influences. Human Ecodynamics discuss how people have been affecting, and affected by environmental variables around them since the beginning of time. Archaeologists are peculiarly well placed to link culture and nature together as the discipline discerns thriving socio-cultural and biological traditions. This thinking is applied to the way in which we conduct our studies of the world around us, and to the boundaries between the various disciplines and sub-disciplines into which we sub-divide the subject matter of investigation.
