Scale Mismatches in Social-Ecological Systems: Causes, Consequences, and Solutions

Abstract

Scale is a concept that transcends disciplinary boundaries. In ecology and geography, scale is usually defined in terms of spatial and temporal dimensions. Sociological scale also incorporates space and time, but adds ideas about representation and organization. Although spatial and temporal location determine the context for social and ecological dynamics, social-ecological interactions can create dynamic feedback loops in which humans both influence and are influenced by ecosystem processes. We hypothesize that many of the problems encountered by societies in managing natural resources arise because of a mismatch between the scale of management and the scale(s) of the ecological processes being managed.We use examples from southern Africa and the southern United States to address four main questions: (1) What is a "scale mismatch?" (2) How are scale mismatches generated? (3) What are the consequences of scale mismatches? (4) How can scale mismatches be resolved? Scale mismatches occur when the scale of environmental variation and the scale of social organization in which the responsibility for management resides are aligned in such a way that one or more functions of the social-ecological system are disrupted, inefficiencies occur, and/or important components of the system are lost. They are generated by a wide range of social, ecological, and linked social-ecological processes. Mismatches between the scales of ecological processes and the institutions that are responsible for managing them can contribute to a decrease in social-ecological resilience, including the mismanagement of natural resources and a decrease in human well-being. Solutions to scale mismatches usually require institutional changes at more than one hierarchical level. Long-term solutions to scale mismatch problems will depend on social learning and the development of flexible institutions that can adjust and reorganize in response to changes in ecosystems. Further research is needed to improve our ability to diagnose, understand, and resolve scale mismatches in linked socialecological systems.

Impacts of Nomad Sedentarization on Social and Ecological Systems at Multiple Scales in Xinjiang Uyghur Autonomous Region, China

“…Large-scale social and ecological systems consist of subsystems at smaller scales, and changes that occur at a given focal scale may have unexpected impacts at larger and smaller scales (Pelosi et al 2010). The results of any study will therefore vary according to the scale or scales chosen for the analysis (Gunderson and Holling 2003;Cash et al 2006;Cumming et al 2006;Zurlini et al 2006;Wiens and Bachelet 2010). For instance, management practices that are effective at a certain scale may be unable to achieve the same results at other scales.…”

We adapt … but is it good or bad? Locating the political ecology and social-ecological systems debate in reindeer herding in the Swedish Sub-Arctic

“…The SES approach's central tenet is that systems are characterized by constant change that is not understood by analyzing its components in isolation but rather by the relationship between building blocks (Rogers et al 2013). Of particular interest is the interaction between social and ecological subsystems (Cumming et al 2006;Duraiappah et al 2014). System level change can be prompted by internal processes, inherent to both social and ecological subsystems, (Holling 1986;Westley et al 2013) or triggered by exogenous events and framed in terms of disturbances (Carpenter et al 2001), or perturbations (Adger 2000).…”

Visualizing Stakeholder Perspectives for Reflection and Dialogue on Scale Dynamics in Social–Ecological Systems

“…Different societal actors maintain different perspectives on spatial levels and time frames (Cumming et al, 2006;Scott, 1998;Wilbanks & Kates, 1999). Research and thought on human perspectives on space and time has a long history, initially in philosophers-for example, Heidegger (1962), Husserl (1964), and Kant (1965Kant ( /1781.…”
