High geomorphic activity places communities at risk to landscape changes that include coastal erosion, landslides, river floods, and soil erosion. Moreover, human impacts on geomorphology (both direct and indirect) can seriously accelerate natural processes increasing this risk. Regardless of our general understanding of geomorphic processes causing these landscape changes, it remains a challenge in geomorphology to foresee events and provide information and warnings to vulnerable communities. Failure to predict and explain geomorphic events is partly due to non-linear behaviour inherent within geomorphic systems that display disproportional responses to perturbations. Likewise, prediction is made difficult by the broader social context (e.g. sustainable development, human behaviour, and population dynamics) in which these events occur. As such, particular landscape changes, both desirable and undesirable, may be regarded as emergent phenomena of large complex systems which are characterized by multiple domains (e.g. geomorphic processes, society, climate and/or economic changes) and feedbacks between geomorphic processes and society. Although geomorphology contributes to and is affected by human society, much of the existing research investigating landscape changes does not capitalize on interdisciplinary knowledge that can result from geomorphologists working together with disciplines, such as the social sciences. We welcome participation from all researchers who can contribute to a greater understanding of the complex set of relationships between geomorphology and people. Submissions can include, but are not limited to empirical and modelling studies that investigate anthropogenic changes to the landscape, sustainable development, mitigating impacts of climate change, community risk/resilience, positive/negative feedbacks, thresholds/tipping points, spatial/temporal scales, river rehabilitation, land use change, methodologies of monitoring and assessment of human impact, and application to hazards mitigation.
