Catastrophic soil erosion coincided with wetter conditions and the transition from hunter-gathering to agropastoralism in the Altiplano region of the central Andes.<\/p>\n

The study published in\u00a0Nature Communications<\/a> was conducted by an international group of researchers from Switzerland, Czechia, Germany, and Denmark, including GF\u00da senior researcher, Dr John Jansen<\/a>, who conceptualized the approach together with the lead auther, Dr Kristina Hippe.<\/p>\n

Key to the study was the measurement of rare isotopes in soils and rocks created by the bombardment of Earth\u2019s surface by cosmic rays. Quantifying the abundances of in situ-produced cosmogenic carbon-14, beryllium-10 and aluminium-26 directly on farmland hillslopes is a new advance in the study of how human activities have shaped landscapes over millennia.<\/p>\n

These findings join the growing support for a strong human imprint, known as the Early Anthropocene, beginning thousands of years before the Industrial Era.<\/p>\n
