This working group met for the first time at the University of Southampton, UK, in 2010 to consider how social and biophysical records could be integrated to study recent human-environment relationships. The group ended in 2015.
This project resulted in a synthesis paper published in The Anthropocene Review (Dearing et al. 2015). The working group also spawned other work themes and publications, notably the use of paleorecords in studies of ecosystem services (Dearing et al. 2012), regional safe operating spaces (Dearing et al. 2014), and complex system behavior, like critical transitions (Wang et al. 2012).
This last theme has been taken up specifically by the working group Aquatic Transitions which started in 2014. A PAGES meeting on ‘Dynamics of socio-ecosystems on a changing Earth: sustainability or collapse?’, will be held in May 2016 to discuss the creation of a follow-up working group to Regional Integration.

Regional Integration overview
There is a need to understand how society and the environment have evolved over multi-decadal timescales to create modern landscapes.
This can be achieved through integrating instrument, document, paleoenvironmental and archaeology records within regions to produce ‘socio-environmental profiles’. Such profiles are especially important to the development of policies and strategies in regions where successful management of key environmental processes, ecological services and their interaction is critical, for example, within natural wildernesses, biodiversity hotspots, climate change hotspots or regions projected to be particularly vulnerable to combinations of stressors.
The group initially integrated past evidence for environmental processes and ecological services for selected regions that were projected by the IPCC and others (e.g. Giorgi 2006) to be climate change “hotspots”. It compiled and integrated records in order to:
1. Identify drivers of change,
2. Track socio-environmental trajectories,
3. Establish levels of modern resilience and vulnerability,
4. Provide the basis for the development and validation of dynamic models for scenario production.
The group aimed to promote and provide new integrations of historical information at regional scales in order to provide a stronger basis for developing strategies for sustainable management and adaptation to global environmental change.
