ScopeTowards development of effective mitigation and adaptation strategies for climate change, it is important to understand how the human and natural Earth systems interact with each other. For instance, mitigation and adaptation policies associated with land cover change may influence atmosphere-land fluxes of carbon, water and heat. A large-scale deployment of bio-energy crops may give impact on bio-diversity as well as the global carbon and hydrological cycle. Conversely, future climate change can affect the human system, including water and food resources (e.g., agricultural, pastoral and fishery products), infrastructure development and labor environment, and human health. Considering those bidirectional feedbacks may better inform mitigation and adaptation policies; it may also be useful to address such challenges more coherently. The primary goal of this session is to provide an overview of interactions between the human and natural Earth systems on the global scale. We also welcome regional and local studies and contributions on one-way interactions (i.e., climate-to-human or human-to-climate).
