연안은 각종 생산 활동과 생물다양성과 같은 전통적 중요성뿐만 아니라 생태학적ㆍ경제학적ㆍ사회적 중요성을 가지고 있다. 이 논문은 지속가능한 연안관리를 위한 생태경제학적 지속가능성에 대한 체계를 정립하고, 연안에 대한 통합 환경관리의 적용을 위해 문제평가, 정책우선순위, 정책형성과 적합한 측정에 의한 정책시행, 이해관계자의 참여를 고려한 적응적 절차, 요인-압박-상태-영향-대응(Driving forces-Pressure-State-Impact-Response: DPSIR)체계에 의한 연안통합 환경관리평가 및 지속가능한 연안관리를 위한 측정방법과 수단을 검토한다. 또한, 생태경제학적 관점에서의 연안관리를 위한 고려사항과 지속가능한 연안 거버넌스를 위한 지침으로서의 리스본원칙-책임성/규모조화/예방적/적응적 관리/전부원가배분/참여원칙을 소개하고, 리스본원칙에 따라 평가된 연안에 대한 문제점의 직접적 효과를 해양생태계시스템에 따라 체계화한다. 하지만 이와 같은 생태경제학적 접근에 의한 지속가능한 연안관리는 현실적으로 많은 어려움이 있다. 체계적 다기준모델을 이용한 지역 연안관리에 대한 지속가능성평가방법의 도입, 연안경제의 투입-산출모델(input-output model)을 해양생태계정보(어획량, 서식지파괴 및 생태계상호작용)와 통합함으로써 생태학적-경제학적 상호작용의 직간접적 효과를 파악하는 경제학적/생태학적 통합모델의 개발이 필요하다. In addition to traditional importance of the coastal zones such as sources of primary and secondary production, and biodiversity, their interrelated ecological, economic, and social importance is better appreciated. This paper summarizes the concepts of ecological economic sustainability for coastal management, and the application of integrated environmental management as an analytical framework and general methodology to support coastal management. Integrated management includes adaptive process, which has to consider interactively problem assessment, policy priorities, the formulation of policies and their implementation in adequate measures, and stakeholder involvement, adopting the driving forces-pressure-state-impact-response (DPSIR) framework. The "lisbon principles"(responsibility, scale-matching, precaution, adaptive management, full cost allocation, and participation) are introduced as a core guidelines for sustainable ocean governance. In order to overcome various problems on implementing sustainable coastal management in terms of ecological economic approach, however, integrated ecological-economic models as multi-criteria model and input-output model of a coastal economy with a model of a marine food web should be employed.

An economic appraisal of a proposed marine ranching project is analysed using capital budgeting model such as net present value(NPV) and internal rate of return(IRR) as well as sensitivity analysis and goal seeking model. Of the factors for economic appraisal, direct benefits are to be determined by estimated harvest, prices and costs incurred by catching fishes, and indirect benefits include the additional economic effect of recreational fishing. And judging the worth of these project options depends upon the choice of discount rate of which 8.5% is recommended here. On the basis of estimated production, prices and coats the project is expected to yield NPV=615 million won and IRR=8.8%, which is quite accepted for an economic feasibility, under the first scenario, and NPV= -127 million won and IRR=7.93%, which is rejected, under the second scenario. Sensitivity analysis has been performed by calculating the switching value and sensitivity indicator in respect of the main project parameters. The results suggest that the project NPV and IRR are especially sensitive to fishes(rock fish and other rock fish) prices and fixed costs. Finally goal seeking analysis is carried out in order to reach a desired level of performance like NPV=0 in respect of the amount of hatchery-reared juverniles, the prices and the discount rate.

As a contribution to developing fishery stock assessment, optimum sustainable yield and its international standards such as MSY, MEY, and dynamic MEY for six recommended fisheries are developed using bio-economic models. For selecting the appropriate model, five models - Schaefer, Schnute, Walters and Hilborn, Fox, and CY&P models are tested in effort and catch data of six species. Surprisingly all the models except the CY&P model failed to satisfy statistical standards such as goodness-of-fitness and reliability. Generally, the CY&P model holds good fitness and statistically significant level for all of six fisheries. However, the CY&P model for squid, where the intrinsic growth rate is high, could not explain MSY, MEY, and dynamic MEY appropriately. This study makes a contribution to develop the modified model for the intrinsic growth rate of 1. The reformulated model represents the results reasonably even though the estimated equation has not good fitness. Although most of the CY&P models appear to have good fits and validated results for some cases, these models also seem to be quite sensitive to parameters which means a more stable model should be developed and data should carefully be handled. In particular biological and technical interactions such as multispecies, predator prey relationship, age structure and mortality should be taken into account. In addition, economic factors and fishing efforts such as price, cost, technical change and a reasonable function of fishing input should simultaneously be considered.
새로운 패러다임으로서의 Blue Economy에 대한 기초설계와 실재

Six volumes in series since Blueprint for a Green Economy (Pearce et al., 1989) set out a green economy which focuses on the relationship between environmental sustainability and economic growth, and the prospect of achieving environmentally sustainable economic growth. In Korea, 'the Basic law for Low Carbon and Green Growth' was enacted as a comprehensive national development strategy in 2010. The paper is to deal with the relationship between sustainable development and green growth and to design the basic idea and reality of a blue economy. As an ocean and coastal-friendly-oriented economic development model, the blue economy should play a major role to implement specific strategies for national policy of green growth in ocean and coastal areas, keeping the concept of sustainable development. In order to accomplish the blue economy, the environmental Kuznets Curve, valuation of environmental resources, extended benefit-cost analysis, environmental accounting system and economic incentive instruments are employed.
