Abstract
The use of coastal resources is expected to become more diversified and advanced in the near future, as reflected in the recent industrial and public interests toward waterfront areas. This increased use of coastal land and shallow sea area, inevitably, leads to various conflicts, such as a competition for coastal zone development and marine preservation among traditional users and new comers. To help decision makers in evaluating adequate policy issues for integrated management of sustainable resource use and environmental preservation, this paper presents a system of economic -ecological models that deal with such complexities of multiple resource use, dynamic inter-dependence of marine ecosystem, and so on.
An empirical model is constructed based on the case study of Harima-Nada (eastern part of Seto Inland Sea) in such a way that combines an input-output model of coastal economy with an ecological model of marine resource in order to coordinate resource allocation and environmental pollution. The constructed model, validated by the economic-ecological data in 1985, is used to evaluate policy options in terms of regional economic growth, construction of sewege system, and preservation of natural coast.
