The originality of the session is to emphasize on the central position of human activities in environmental research (both terrestrial and atmospheric), as a driving factor and/or a response, by combining different spatio-temporal scales.
Continental environments (under various climatic conditions) experience profound societal and physical changes, which prompt scientists to investigate the complex interactions between environmental functioning and human activities.
The complexity originates from the multiplicity of factors involved and resulting spatial and temporal variabilities, of their multiple origins in time (historical integration) and/or legacy.
As a consequence, causal links in this societal-environmental relationship are difficult to establish but, it is fundamental to understand these causal links to adapt, conserve, protect, preserve and restore the functioning of the environment as well as human activities. From this point of view, the geographical approach highlights the relationships (or their absence) through the expression of the spatial and temporal trajectories of the processes studied by clarifying the observation of signals.
The ensuing issues on the relevance of indicators used in different supports of nowadays research (imagery, archives, models ...) are raised as a methodological open up.
In this context, oral and poster presentations dealing with any studies related to the following issue(s) are welcome:
- human forcing on the environments and environmental resilience
- response of socio-systems to environmental changes
- scenarios, prospective and retrospective models of the evolution of environments and human activities
- management modes (adaptive management) of anthropised continental environments, reciprocity, mutual benefits (ecosystem services), positive feedback

The session may include the following methodological aspects:
- in situ metrology,
- statistical and numerical modeling,
- spatio-temporal analysis,
- remote Sensing,
- surveys,
- landscape analysis,
- paleoenvironmental approach,
at various scales:
- spatial scales, from the station and site through watershed,
- time scales from the event to the Holocene.
