Bronze Age soil erosion and land-use change in the French Prealps
Lake-sediment proxies record increased erosion associated in part with changing agricultural practices in the French Prealps.
What is the evidence?
observation
Lake-sediment proxies record increased erosion associated in part with changing agricultural practices in the French Prealps.Review and provenance
Specialist reviewer: not recorded. Review date: not recorded.
Dataset workflow: proposed. This is separate from specialist review.
Confidence describes the stated assessment; it does not certify expert approval. How review works.
Chronology
Dating intervals may describe uncertainty or phases; their width alone does not establish event duration.
1600 BCE–1200 BCE
Precision: broad range
moderatePreferred range used by the event. Plausible bounds and alternative models remain explicit rather than averaged.

Interpretation and caveats
Agricultural expansion is a plausible contributor, but climatic forcing, fire and local land-use patterns must remain in the causal model.

Timeline role: regional core
People and places
Why it matters to the timeline
The event directly addresses local environmental records and agricultural systems in the Alpine zone.
Alternative interpretations
- Climate variability may explain part of the erosion signal independently of agricultural change. (moderate confidence)
