Cultural regimes written into soil isotopes

Cultural isoscapes of past societies

ISOCULTURE

Isotopic & social organisation of cultural land-use and regional epigenetic legacies

A new framework for reading soils and landscapes as long-term archives of human land-use decisions.

What is IsoCulture?

IsoCulture is a conceptual framework for interpreting stable isotope patterns as outcomes of long-term cultural land-use regimes.

What it studies

Real archaeological landscapes shaped by historically grounded land-use practices.

How it works

By integrating archaeology, soil science, and geochemistry to link isotopic variability with long-term social decisions.

IsoCulture shifts isotope research from short-term biomass signals to soils as long-term cultural archives, enabling historically grounded interpretations of human–landscape interaction.

Regions of Investigation

Core regions, pilot studies, and comparative case studies included in the IsoCulture framework.

Geological Context

Geological background provides the long-term environmental framework controlling soil formation and baseline geochemical conditions. The map uses the official 1:50,000 geological map of the Czech Republic via a live WMS service.

Guy Bar-Oz

Guy Bar-Oz

Professor of Archaeology at the University of Haifa and former PI of an ERC Consolidator Grant (2015–2020) focused on resilience and collapse in the Negev Desert.

He will coordinate sampling activities in Israel, drawing on his long-term research sites and well-documented monastic landscapes of the Negev Desert, and contribute to the development of the IsoCulture concept into ERC-oriented studies (M. Janovský as PI).
