지탱가능한 발전을 위한 서울시 환경용량의 산정과 정책적 함의

Abstract

The purpose of this paper is estimating environmental carrying capacity of Seoul Metropolitan Area for a sustainable city management using system dynamics modeling. A sustainable development requires society to define sustainability constraints or environmental limits, environmental carrying capacity. Environmental carrying capacity can be defined as the level of human activity which a region can sustain at an acceptable quality of life level . This concept of environmental carrying capacity has several important applications to sustainable city planning and management. If the limitation of a human activity can be supported by a scientific data on carrying capacity, the resulting decision and actions could more easily win public support for a sustainable development. However, one of the key issues is how to operationalize the carrying capacity. In this paper, the environmental carrying capacity was operationalized as a maximum number of industry structure, population, and housing that can sustain certain level of environmental quality of Seoul Metropolitan Area. The model developed in this paper consisted of 5 sectors ; population, housing, industry, land, and environmental sector. The model limits its main focus on the NO₂ level of ambient air of Seoul. Carrying capacity of Seoul Metropolitan Area was estimated by figuring out the maximum number of population, industry structure, housing at an equilibrium point that sustain a desirable NO₂ level. Based on the model estimation, several policy implications for a sustainable city management was discussed.
