An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group at Pompeu Fabra University, has advanced in the understanding and preservation of archaeological sites and in improving their analysis and surveying, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a rapid, inexpensive, non-invasive procedure, which enables generating an additional archaeological record from the anthropogenic deposit by analysing chemical elements, combined with geostatistics.

Researchers Use Archaeological Data to Improve Climate Models
Written by AZoCleantechApr 15 2021
Climate modeling is future facing, its general intent to hypothesize what our planet might look like at some later date. Because the Earth s vegetation influences climate, climate models frequently include vegetation reconstructions and are often validated by comparisons to the past. Yet such models tend to get oversimplified, glossing over or omitting how people affected the land and its cover.
The absence of such data led to LandCover6k, a project now in its sixth year that includes more than 200 archaeologists, historians, geographers, paleoecologists, and climate modelers around the world.
To improve climate models, an international team turns to archaeological data The project, called LandCover6k, offers a new classification system that the researchers hope will improve predictions about the planet’s future and fill in gaps about its past. The LandCover6k project uses a hierarchical classification system. An upper-level category captures an idea at its broadest, with several distinct subcategories funneling down from there. This quartet show the subgroups of the “pastoralism” category (from top left, clockwise): “Anchored pastoralism,” shown as sheep and cattle near a settlement; “ranching,” with cattle enclosed in pasture land; “mobile, irregular,” with sheep and goats moving along a less well-trodden path; and “mobile, regular,” with those same animals shepherded along a specific path.
