| Description: | Landscape evolution has historically been described using the interactions of biological and physical processes. However, chronic anthropogenic impacts from low-intensity land use and climate change complicate these interactions and in some cases lead to significant shifts in the rate and trajectory of geomorphologic change. Additionally, we lack quantitative methods for describing certain natural processes across a range of timescales and how they might be impacted by human activities. A quantitative understanding of biological, physical, and anthropogenic forcings is required to manage coupled earth systems for sustainable natural resource use. This session solicits papers that describe the relative roles of physical, biological and anthropogenic mechanisms in landscape evolution, and how these roles might shift over time. We encourage interdisciplinary studies that utilize novel methods and/or long-term environmental records to identify and quantify the major earth systems processes (including human activities) and their interactions that control landscape evolution. |
