Hunter-gatherer land management in the human break from ecological sustainability

Evidence that human societies built on agricultural subsistence have been inherently ecologically unsustainable highlights the value in exploring whether any pre-agricultural subsistence approaches were ecologically sustainable or nearly so. The land management practices of some hunter-gatherer societies have been portrayed as sustainable, even beneficial. Research suggests such practices may fruitfully inform contemporary land management. As a human subsistence foundation, however, they may not have been ecologically sustainable. Figuring centrally in the late Pleistocene shift from immediate-return to delayed-return hunting and gathering, they enabled population growth, helped make possible the development of agriculture, and appear to have caused early environmental degradation. Consistent with this argument is research locating the origins of the Anthropocene near the Pleistocene-Holocene boundary, as societies were taking greater control of food production. It appears then that immediate-return hunting and gathering, which involved little or no land management, was the human lifeway most closely approaching ecological sustainability. Wider recognition of this idea would assist in understanding and addressing today's ecological challenges.
