Thinking in Terms of SocialEcological Systems: Connecting climate change impacts to human communities Miranda H. Mockrin Rocky Mountain Research Station USDA Forest Service Fort Collins, CO Workshop on Forest Community Vulnerability and Adaptive Capacity in the Context of Climate Change November 7-10 2011, Lubrecht Experimental Forest, Montana Social-ecological systems— definitions and history • Combines ecosystems and social science to address the linked ways that social systems and ecology interact • Emerged from Stockholm Resilience Center, always linked to resilience as a concept • Same as ‘coupled human-natural systems’ Social-ecological systems— definitions and history • “We hold the view that social and ecological systems are in fact linked, and that the delineation between social and natural systems is artificial and arbitrary” Berkes et al. 2003. Navigating social-ecological systems: building resilience for complexity and change. Cambridge University Press. 393 pp. Social-ecological systems— definitions and history • When separated, in the past, ▫ social science sometimes focused solely on human interactions, with environmental context seen as constant or unimportant ▫ ecologists concentrated on ‘pristine environments’ and saw humans as external agents, minimizing institutional and policy context (Liu et al. 2007). Social-ecological systems— definitions and history • Grew out of systems ecology/systems approach, with an emphasis on linkages, feedbacks, and thresholds among components. • Response to classic utilitarian approaches that considered resources in isolation ▫ e.g., harvesting fisheries with a fixed species-specific quota ▫ Classical approach assumed scientific knowledge/human control could result in desired management outcomes Social-ecological systems—limitations • Despite emphasis on joining ecology and social science, usually focused on a natural resource or ecological system/case study • Questions about these systems/resilience and work with social science (Davidson 2010 Society and Natural Resources) Examples of climate change & SES • Chapin et al. 2006.

Juvenile and adult fish populations are affected by different environmental and exploitation pressures and are linked through immigration and recruitment. Adults are harvested by the sportfishing and artisanal fleets, while the largely immature individuals are impacted by the industrial shrimp fleet via bycatch. The effort employed by the sportfishing and artisanal fleets are driven by the returns to each respective sector Social-Ecological Systems & USFS • Southern Forest Futures Project • Resources Product Assesssment Social-Ecological Systems & USFS • Southern Forest Futures Project ▫ Forecasting probable changes in southern forests between 2010 and 2060. ▫ Presents a range of futures or scenarios of the South’s forests Influences such as urbanization, bioenergy, climate change, land ownership changes, and invasive species. Goal: inform land management and policy by providing these forecasts about potential long-term change in forests of the 13 southern states. 2010 RPA Scenario Analysis and Modeling Systems Basic Assumptions Global Forest Products Model Global SRES Scenarios Socioeconomic US Forest Products Model Timber Supply US Scenarios Bioenergy Climate US Forest Sector Modeling System Macroeconomic Translated/ Downscaled Forest Dynamics Model Demographic Forest Area Land Use Model Forecasts of Ecosystem Services/Responses Forest Range Carbon Water Wildlife Recreation • Wood Products • Forage Supply • Sequestration • Supply • Climate Stress • Participation Landscape Pattern • Condition • Condition • Vulnerability • Bird Diversity • Days of Activity • Fragmentation • Edge Social-Ecological Systems & USFS • Strong tradition of considering both social and ecological science in resource assessments ▫ Emphasis on modeling and ecological approaches ▫ Forested ecosystems/resources ▫ Large spatial and temporal scales Connecting Climate Change Impacts to Human Communities: Thinking in terms of socialecological systems Miranda H.
