• Resumen

  • This research aims at understanding how recent (19th to 21st centuries) warming and increasing human activities have affected the geomorphological dynamics of the Cantabrian region, subjected to a comparatively high human pressure during this period. In this work, we use a multi-archive and multi-site approach, integrating available high-resolution estuarine (Tina-Menor, San Vicente, Rabia, Suances, Maruca, Santander, Santoña, Muskiz and Urdaibai) and lake (La Cueva, Enol) sedimentary records located across W to E longitudinal and altitudinal (0-1500 m.a.s.l.) transects. Preliminary results indicate a marked increase in sedimentation rates during the so-called ‘Great Acceleration’, recorded after the second half of the 20th century and mainly driven by the economic growth and associated human impact in this area. The extension of this research to other lacustrine watersheds located at different altitudes and subjected to different levels of anthropic pressure and the application of other proxies (sedimentology and geochemistry) will clarify the relative contribution of climate change and human impact to reconstructed environmental changes.
