Research assessment
statement
Expansion or reorganization of Bronze Age agriculture contributed to increased soil erosion in the Lake Bourget catchment.chronology test
Cultivation proxies, vegetation opening and erosion indicators should rise in compatible phases within chronological uncertainty.geography test
The strongest signal should occur in catchments exposed to land-use change rather than uniformly across all Alpine lakes.supporting evidence
Millet biomarker, pollen and sediment proxies overlap in the Lake Bourget sequence.Evidence and sources
