  • This study introduces the navigational environment database(DB) compiling water depth, sediment type and marine managed areas (MMAs) in coastal waters of South Korea. The water depth and sediment data were constructed by combining their sparse points of electronic navigation chart and survey data with high spatial resolution using the inverse distance weighting and natural neighbor interpolation method included in ArcGIS. The MMAs were integrated based on all shapefiles provided by several government agencies using ArcGIS because the areas should be used in an emergency case of ship. To test the validity of the constructed DB, we conducted a test application for grounding and anchoring zones using a ship accident case. The result revealed each area of possible grounding candidates and anchorages is calculated and displayed properly, excluding obstacle places.

  • The creation of marine protected areas is an important aspect of marine ecosystem sustainability. However, South Korea has not achieved its Aichi Biodiversity Target to designate 10% of its sea as marine protected by 2020. Local residents have strong opposition to the designation of protected areas in South Korea; there has been little trust in the government since the 1970s, when residents felt that their property rights were being ignored in favor of creating national parks. Here, we present a case where creation of a marine protected area was led by residents of TongYeong City. The success of a participation income project to remove marine debris in the city seems to be an important factor that led to the designation of the marine protected area. The case of TongYeong City is compared with that of nearby Geoje City, where an ecologically important stream has not been designated as a wetland protection area, although a similar participation income project enrolled the city's residents. The comparison provides a tentative assessment of the conditions needed to increase trust among residents. The results suggest that, if the projects are well-designed and well-managed, participation income projects to remove marine debris can be effective in building trust among stakeholders in potential marine protected areas.

  • This study presents an integrated evaluation method to assess the level of achievement of quantitative expansion goals and qualitative improvement goals based on the Aichi Biodiversity Target 11 for quantitatively expanding and qualitatively improving national protected areas. The quantitative evaluation indicators for national protected areas are the percentage of terrestrial and inland water areas protected and the percentage of marine and coastal areas protected. The quantitative evaluation indicators for national protected areas are selected as 6 indicators: 1) ecologically important areas, 2) ecological representativeness, 3) management effectiveness, 4) connectivity, 5) social equity and 6) integration. Ecologically important areas are an indicator which evaluates how many areas of particular importance for biodiversity and ecosystem services are included in national protected areas. Ecological representativeness is to assess how well national protected areas represent the ecosystem. Management effectiveness is an indicator which evaluates how effectively national protected areas are conserved and managed, and connectivity is an indicator to assess how well national protected areas are connected. Social equity is evaluating how equitably national protected areas are managed and the integration is assessing how much national protected areas are integrated into the wilder landscape and seascape. This study is significant in that it provides a perspective of qualitative improvement as well as quantitative expansion of national protected areas for biodiversity conservation through accurately understanding Aichi Biodiversity Target 11.

  • The aim of this study was to analyze the income and productivity of seaweed farmers based on farmed land ownership status. This research was conducted in three provinces on the Sulawesi Island which are ranked among the 10 largest seaweed producers in Indonesia: Central Sulawesi, South Sulawesi and Southeast Sulawesi. The twelve study sites were determined based on 5 special criteria and 792 respondents fulfilled the criteria for seaweed farmers. Data were collected through field surveys and analyzed using qualitative and quantitative methods. Results showed that the seaweed farming areas are considered as private property with 4 types of marine land tenure or ownership status: own land, inherited land, leasehold land and purchased land. The productivity of seaweed farming land had a positive value greater than 1 in South Sulawesi and Southeast Sulawesi, and a positive value of less than 1 in Central Sulawesi. Seaweed cultivation in Central Sulawesi has not been managed effectively. At all sites, the maximum number of growing season cycles was 5 cycles/year. Optimal growing season conditions gave the highest marginal returns at 2-3 cycles/year with additional costs exceeding additional income for more than 3 cycles/year.

  • 현재 해양은 이용과 보전간의 갈등이 심화되고 있어 이를 해양공간의 핵심가치별로 사전에 정의하여 관리하는 실효적인 방법의 도입이 필수적이다. 이에 해양공간계획을 통해 해양을 9개의 용도구역으로 구획하여 관리하도록 하고 있지만 대상 해양공간에서 상호 배타적인 활동이 중첩되는 공간에 대한 분석은 미흡한 실정이다. 이에 본 연구에서는 해양의 핵심가치가 상충되는 공간을 도출하기 위한 자동화 모형을 개발하였다. 해양활동을 분석하기 위해 가용 가능한 해양활동 자료를 수집하고 이중 상호배타적인 해양활동의 분석에 필요한 항목을 도출하였다. 도출된 항목을 법정구역과 특성구역으로 분류한 후 중첩이 발생할 시 우선순위를 지정하기 위해 항목간의 쌍대비교를 통한 상충분석표를 제작하였다. 지정된 우선순위를 바탕으로 자동화 모델을 개발하여 해양의 활동이 상충되는 해역을 도출하여 가시화하고 상충되는 면적을 산출하였다. 이를 활용하여 해양공간계획을 수립함에 있어 주요 이슈가 발생하는 해역을 명확하게 도출하여 의사결정의 효율성을 높일 수 있을 것이라 판단된다.

  • This paper proposes revisions in the law governing assessments of the environmental impact of marine projects. In particular, we suggest strengthening the consultative role of the Ministry for Food, Agriculture, Forestry and Fisheries (MIFAFF), the agency responsible for regulating coastal area utilization and development, in order to improve the system by which fishery resources are managed, thus preventing negative environmental impact. Moreover, such an improved impact assessment statement would include reasonable evaluations of the dispersion of pollutants, such as the suspended solids generated by construction projects, as well as of the dredging, dumping and sand mining involved in coastal area reclamation. Thus, public confidence in the latter would be increased by the development and implementation of standardized and consistent guidelines addressing environmental research, simulation processes and evaluations of data.

  • 우리나라는 1999년 람사르 협약의 국내이행을 위하여 "습지보전법"을 제정하여 환경부와 해양수산부가 각각 내륙습지와 연안습지를 관리하고 있다. 연안습지는 2001년 무안갯벌을 습지보호지역으로 지정하기 시작하여, 2013년 6월 기준으로 총 12개 지역, $218.96km^2$을 습지보호지역으로 지정하였다. 제도가 도입된 지 10년이 지나면서 보호지역 지정 면적이 늘어나는 외형적 성과를 거두었으나, 한편에서는 습지 보전정책이 효과적으로 이행되는지에 대한 의문이 제기되기도 한다. 이 연구에서는 습지 관련 법률과 제도에서 나타나는 문제점을 분석하고, 연안습지 보전 정책의 효과적인 이행을 위한 정책개선방향을 제시하고자 한다.

  • 우리나라와 필리핀을 비롯하여 전 세계적으로 해양생태자원의 중요성을 인식하고 이를 보호하고 보전하기 위하여 해양보호구역을 설정하여 관리하고 있다. 그러나 해양생태자원 보호를 위한 해양보호구역의 수는 늘어난 반면, 대부분의 해양보호구역들이 원래의 설정목적에 맞게 효율적으로 관리되지 못하는 문제점을 안고 있다. 이는 직접적인 이해당사자인 지역주민이나 수산업자들은 해양보호구역의 설정으로 발생하는 긍정적이고 부정적인 영향으로 인하여 해양보호구역의 설정에 찬성과 반대에 대한 논쟁이 지속되고 있기 때문이다. 따라서 본 연구에서는 오래전부터 수산자원의 관리와 보존 및 보호를 위해 제정된 1998년 필리핀 수산업법에 의하여 지방정부 하여금 관할해역의 15% 이상을 수산자원보호구역으로 지정하여 관리해 오고 있는 필리핀 기마라스주 해양보호구역 설정에 대한 사례연구를 실시하였다. 이를 위해서 연구 지역인 기마라스주 두 시의 지역주민들을 대상으로 수산자원을 위한 해양서식지의 보호와 보존을 위해 필요한 해양보호구역 설정논쟁에 대한 인식조사와 지불의사금액(WTP)을 추정하기 위하여 이분선택형 조건부가치측정 설문조사를 실시하였다. 새로이 설정될 해양보호구역 내에서의 어로행위 제한으로 예상되는 경제적 손실 때문에, 과반수 이상인 응답자의 58.7%는 손실에 대한 보상이 이루어져야 한다고 응답하였지만, 수산자원의 보호를 위한 관리방안으로 해양보호구역의 증대필요성에 대해서는 91.4%가 찬성하는 것으로 나타났다. 마지막으로 조건부가치측정법(CVM)을 통하여 기마라스주 산로렌조시와 시부낙시 전체 지역주민들이 부여하는 해양보호구역(375.5ha)에 대한 평균가치는 $1,046,791달러로 추정되었다. 따라서 이러한 연구결과는 우리나라 해양보호구역의 효율적인 관리방안 수립에 유용한 자료로 활용될 수 있을 것이다.

  • Ships and their cargos have been managed safely by positioning report system. However, little attention has been paid to safety of crew's works with danger. The attempt that used PHS inboard was before by the present authors. However, the functions were just voice call and mail exchange. The data acquisition from the terminal by proper control was not possible. Thus the position of the terminal was not available. As for the cell phone of next generation, GPS receiver and wireless LAN are installed by manufacturers. Therefore, we propose a system which uses a cell-phone with GPS receiver on a ship in order to promote the safety of ship's crew. We checked the availability of cell-phone GPS receiver at thirty different points inboard. The positioning was not possible in the areas further than 4m from the window. Then, we proposed the system which follows the positions of the crews and confirms their safety inboard by using the VoIP (Voice over Internet Protocol) function by wireless LAN.

  • As a result of very limited access due to the military confrontation between South and North Koreas for the last five decades, ecosystems in the transboundary coastal area in the western part of Korean Peninsula have been protected from intensive developments in both Koreas. In the core of the recent two military collisions lies the fishery resources represented as blue crabs as well as the politico-military aspect. Increasing development pressures from both sides as reflected in the South Korea supporting the construction of an industrial complex in Kaesung, North Korea, is the main factor which threatens the sustainable resource base in this region. This research is aimed to develop a cooperative management system for the well-preserved transboundary coastal area between South Korea and North Korea. The Pressure-State-Response (PSR) framework of OECD was used to assess environmental conditions, socioeconomic pressures on the environment of the region, and policy responses of both Koreas to those pressures. Protection of ecosystems, peace settlement, and prosperity of the region and the entire peninsula were proposed as the management goals of the cooperative management system. The designation of the area as a Co-managed Marine Protected Area System (COMPAS) through close cooperation among South Korea, North Korea, and international entities was suggested as a way to achieve those goals. Revision of legal and institutional mechanisms, strengthening knowledge base for optimal COMPAS management, integration of the marine protected area and DMZ (demilitarized zone) ecosystem, enhancing stakeholder participation, building international partnership, and securing financial resources were presented as six management strategies.
