Archaeological assessment reveals Earth's early transformation through land use (original) (raw)

2019, Science

Environmentally transformative human use of land accelerated with the emergence of 5 agriculture, but the extent, trajectory, and implications of these early changes are not well understood. An empirical global assessment of land use from 10,000 BP to 1850 CE reveals a planet largely transformed by hunter-gatherers, farmers and pastoralists by 3,000 years ago, significantly earlier than land-use reconstructions commonly used by Earth scientists. Synthesis of knowledge contributed by over 250 archaeologists highlighted gaps in archaeological 10 expertise and data quality, which peaked at 2000 BP and in traditionally studied and wealthier regions. Archaeological reconstruction of global land-use history illuminates the deep roots of Earth's transformation through millennia of increasingly intensive land use, challenging the emerging Anthropocene paradigm that anthropogenic global environmental change is mostly recent. 15 One Sentence Summary: A map of synthesized archaeological knowledge on land use reveals a planet transformed by hunter-gatherers, farmers and pastoralists by 3,000 years ago.
