Landscapes evolve from a range of physical, chemical and biological processes. These processes erode and redistribute sediment and thus circulate nutrients and sequester huge volumes of atmospheric carbon. Earth surface processes provide ecosystem services, yet they can become severe natural hazards, too. The activities of an increasing global population continue to alter rates and magnitudes of earth surface processes on an unprecedented scale. Examples of such human activities include, but are not limited to, land-use-changes and terrestrial infrastructure development, building of dams and reservoirs, coastal engineering, river and marine aggregate mining, and surface mining. Humans have now entered an era in which they impact on sediment pathways and instigate feedback cycles leading to increased resource scarcity, reduced delivery of ecosystem services, increased natural hazards and conflict. This session aims to evaluate the current knowledge on how humans engineer landscape processes and on feedbacks between earth surface processes, their anthropic alterations and the resulting socio-economic repercussions. We invite presentations that shed light on the role of earth surface processes during past, present, and future human-environment interactions. Moreover, we solicit studies on innovative techniques of data collection and modelling to identify new approaches to value and manage sediment.
