Our project’s goals: • Improve understanding of the relative resilience and adaptability of regional Human-Rangifer Systems to the forces for global change • Derive generalized propositions about their functional properties as aspects of the Arctic System.
Common assumptions A Fragile Arctic Ecosystem?
Common assumptions “Highly Adaptable” Indigenous Northerners… (AHDR)
1950-2000 1950-2000 (Nellemann et al. 2001)
Overarching hypothesis The heterogeneity of state factors (e.g., geography, climate change, land-surface changes) and their interaction with unique regional processes (i.e. ecological, socio-economic, institutional, and cultural processes) give rise to differing forms of resilience and vulnerability, with implications to the sustainability of human-environment dimensions of the Arctic System.
Resilience in Human-Rangifer Systems is …the degree to which the ecological and social processes can absorb disturbance, reorganize without loss of basic governing properties, and enable herds and communities to adapt to diverse and dynamic regional conditions, with Rangifer continuing to provide a primary means of support for the local population.

Towards a Synthesis • A retrospective analysis of change to understand driving factors and internal processes • How did they change and how are they different? 2) A comparative analysis cases to understand heterogeneity and its implications to resilience and vulnerability • Why are they different? 3) Develop rule-based simulation models for exploring common system dynamics • What does that tell us about the system?

CARMA Network (Circum-Arctic Rangifer Monitoring & Assessment Network) • ~40 participants from seven countries • Gearing up for intensive IPY monitoring • Interests in remote sensing, field-based studies, community monitoring • Climate; habitat; genetics; energetics; disease and parasites, predation, population dynamics, human uses and responses to change; decision-support tools • We’re helping with the overall synthesis
Where we’re at… • We are facing the normal process challenges of interdisciplinary research, but it seems that past experience helps • We’re grappling with the task of clarifying resilient to whom and resilient for what • We’re trying to stay focused on Social-ecological linkages and integrated measures of resilience that we can operationalizing • We’re grappling with the thorny problem of accounting for regimes shifts and thresholds. • We are initially pleased with our focus on “Relative resilience” – as a useful comparative method for understanding social-ecological vulnerabilities.
