Abstract

TThis paper explores the crucial linkage between societal risk perception and the survival of threatened ecosystems exhibiting non-linear stock dynamics. Perception of risk over specie’s importance and over its survival chances may be subject to resilience and therefore may differ from actual risks. Whereas, ecosystems stand a better chance of survival if they aren’t stressed beyond their resilience thresholds. When an ecosystem’s sustainability and the subjective perception of risks of their loss are both influenced by the stock of a common natural resource, several resource management outcomes are possible, not all of which may ensure the sustainability of the ecosystem. Specifically, the survival of ecosystems becomes dependent upon a combination of several factors including the degree of shift in subjective risks following a crossing of resilience thresholds, the relative proximity of the resilience thresholds in ecological systems and perceived risks and the societal costs of forgone consumption of natural resources.
