Ecological Unequal Exchange: Consumption, Equity, and Unsustainable Structural Relationships within the Global Economy

New Mexico State University, USA

We discuss and elaborate upon the theory of cross-national ecological unequal exchange. Drawing upon world-systems theoretical propositions, ecological unequal exchange refers to the increasingly disproportionate utilization of ecological systems and externalization of negative environmental costs by core industrialized countries and, consequentially, declining utilization opportunities and imposition of exogenous environmental burdens within the periphery. We provide a descriptive overview of theoretical and empirical efforts to date examining this issue. Ecological unequal exchange provides a framework for conceptualizing how the socioeconomic metabolism or material throughput of core countries may negatively impact more marginalized countries in the global economy. It focuses attention upon the global uneven fl ow of energy, natural resources, and waste products of industrial activity. Further, the recognition of the distributional processes of ecological unequal exchange is relevant to considerations of both the socioeconomic and environmental imperatives underlying the pursuit of sustainable development, as it contributes to underdevelopment within the periphery of the world-system. We conclude by highlighting the interconnections between uneven natural resource fl ows, global environmental change, and the challenge of broad-based sustainable development.

Key Words: ecological footprint • ecological unequal exchange • international trade • natural resource consumption • sustainable development
