干旱区生态环境知识资源中心

Social-ecological-systems (SES) scholars have called for increased elaboration of the social dimensions of natural systems. Although a strong body of research explaining adaptive or maladaptive resource use exists, the integration of knowledge related to values, perceptions, and behaviors is less developed. Perceptions are particularly useful when one seeks a broad-scale view of the judgments that people implicitly or more automatically make in relation to nature and/or how people might rapidly and intuitively interpret the meaning of ecological status and change. Environmental perceptions are also distinct from the longer tradition of direct elicitation of environmental values as related to reported environmental behavior; and from understanding of perceived environmental health risks. Empirically, we thus explore what an architecture of environmental perceptions might be. Our goal is to advance an SES-relevant focus on the qualities that people intuitively assign to air, water, and soil in general and in particular. Initial qualities were first developed using mental model interview responses, which were then converted to psychometric rating scales administered across two surveys: an initial pilot survey and a large-scale follow up survey. In the pilot study, four factors-resilience, tangibility, complexity and sensory-emerged as primary (n = 697). In our large-scale follow up (U.S. nationally representative sample, n = 2500) we retested the two strongest factors (tangibility and resilience) within specific ecotypes or contexts (forests, rivers, oceans, deserts, urban, and rural). Resilience emerged a particularly powerful component of environmental risk perception, a factor comprising four attributes: recovers easily from human impacts, self-cleaning with time, mostly pure, and easy to control. Results suggest a greater mandate for explicit understandings of the intuitive foundations of perceived environmental risk as might explain environments we regard as vulnerable or resilient, healthy or not.
