Used Planet: A Global History

Used Planet: A Global History

In Used Planet: A Global History, published in PNAS in 2013, we synthesized scientific evidence and theory on the emergence, history, and future of land use as a process transforming the Earth System. In the paper, we contrast two spatially explicit global reconstructions of land-use history, HYDE 3.1 (Klein Goldewijk et al, 2011) and KK10 (Kaplan et al, 2011), showing that reconstructions that include land-use intensification (KK10) produce more plausible assessments of our planet’s history, with a biosphere and climate long ago transformed by people
