As Richard I. Ford explains in his preface to this volume, the 1980s saw an “explosive expansion of our knowledge about the variety of cultivated and domesticated plants and their history in aboriginal America.” This collection presents research on prehistoric food production from Ford, Patty Jo Watson, Frances B. King, C. Wesley Cowan, Paul E. Minnis, and others.

This book in the SAA Press Current Perspectives Series provides a broad overview of the development of agriculture and other forms of resource management by the Native peoples of North America. Its geographical scope includes most of the continent’s temperate zone, but regions where agriculture took hold are emphasized. Temporally, this volume looks back as far as the first indigenous domesticates that emerged in the midcontinental region and follows the story into the era of European conquest.

Organized into four sections, the twelve chapters of Rivers of Change are concerned with prehistoric Native American societies in eastern North America and their transition from a hunting and gathering way of life to a reliance on food production. Written at different times over a decade, the chapters vary both in length and topical focus. They are joined together, however, by a number of shared “rivers of change.”

During virtually the entire four-million-year history of our habitation on this planet, humans have been hunters and gatherers, dependent for nourishment on the availability of wild plants and animals. Beginning about 10,000 years ago, however, the most remarkable phenomenon in the course of human prehistory was set in motion. At locations around the world, over a period of about 5,000 years, hunters became farmers. Far more than the domestication of plant and animal species was involved in this revolution, which was accompanied by massive changes in the structure and organization of the societies that adopted agriculture and by a totally new relationship with the environment. Whereas hunter-gatherers live off the land in an extensive fashion, exploiting a diversity of resources over a broad area, farmers utilize the landscape intensively. The implications of these changes in human activity and social organization reverberate down to the present day.

Although the need to study agriculture in different parts of the world on its “own terms” has long been recognized and re-affirmed, a tendency persists to evaluate agriculture across the globe using concepts, lines of evidence and methods derived from Eurasian research. However, researchers working in different regions are becoming increasingly aware of fundamental differences in the nature of, and methods employed to study, agriculture and plant exploitation practices in the past. Contributions to this volume rethink agriculture, whether in terms of existing regional chronologies, in terms of techniques employed, or in terms of the concepts that frame our interpretations. This volume highlights new archaeological and ethnoarchaeological research on early agriculture in understudied non-Eurasian regions, including Island Southeast Asia and the Pacific, the Americas and Africa, to present a more balanced view of the origins and development of agricultural practices around the globe.
