Sedentary Lifeways: Sedentism
While they are not exciting in appearance, settled agricultural
villages like this early example at Ban Po,
China (reconstructed on the right), represented a radically new way of life
for human
beings, unlike anything that had existed
before.
First, agriculture means sedentism--living permanently in one place. This was itself new to human beings, and it may have seemed very constraining to the first people to experience this way of life. Living in one spot permanently means exploiting a relatively small amount of land very intensively (rather than exploiting a large amount of land extensively, as hunter-gatherers did), and over a long period of time.
To understand how radical this change was, it is necessary
to consider carefully both the advantages and disadvantages of gaining one's
living from one piece of ground and the effects of such a way of life on
the environment.
The Emergence of Sedentary Agriculture
The earliest agricultural sites in the world have
been found in the Near East: in the Nile Valley and Western Asia, in valleys
of the Zagros Mountains in Iran, in Anatolia (modern Turkey, shown above),
in northern Syria, and along the Jordan River valley. Around 10,000 to 12,000
years ago, agriculture began to emerge as a new specialized way of life,
replacing hunting and gathering. In this region of the world, the changes
in climate which accompanied the most recent retreat of the glaciers may
have triggered the development of agriculture.
Agriculture also emerged in several other regions around the world somewhat later, as other human communities made the same kinds of discoveries and evolved similar cultural adaptations. These regions include the north China plain, in south and southeast Asia, in sub-Saharan Africa, in North and South America. Scholars debate whether all of these regions came to the discovery of agriculture independently or as a result of knowledge diffused from other cultures. They also debate whether the changes were driven by climate change or population pressures. Frequently, the available evidence is inconclusive.
In any case, for the past 10,000 years, agriculture has spread over the globe and evolved and assumed many forms, depending on the plants and animals available locally and the ability of imported life forms to adapt to new conditions. Agriculture as a mode of life has been enriched by many discoveries and inventions around the globe, and by borrowing techniques and crops and domestic animals from other regions. Gradually, sedentary agriculture became the dominant mode of life in nearly all of the areas of the world inhabited by humans. In addition, it formed the basis for a new way of life which we call civilization.
