This mini review examines the habitat connectivity and effectiveness of Korean Marine Protected Areas (MPAs) in the Yellow Sea Large Marine Ecosystem (YSLME) region. We first reemphasize that the Korean region of the YSLME is a single ecosystem (ecoregion) given the biophysical distribution patterns. The MPAs within the YSLME contribute about 50% to the total MPAs in Korea, accounting for about 10% of the territorial sea waters of Korea and 20% of the waters of YSLME on the Korean side. By area, national parks account for nearly 45% of the MPAs, followed by the wetland protected areas at 25%, with other types of MPA comprising the remaining 30%. Large MPA (> 100 km²) is the dominant type of MPA, accounting for 90% of the total area. We find that MPAs in the region are connected physically and perhaps also genetically. However, the level of protection was found to be low, and a no-take zone is rarely implemented. In addition, interrupted freshwater discharge caused by river-mouth dams poses a major hindrance to the physical connectivity of the MPAs. Restoration of the river-mouth dams and strengthened regulation on MPAs, with further expansion of MPAs in line with the current development of post-2020 global biodiversity frameworks, should be priorities for better management of marine resources. The newly revised law incorporating the concept of "Marine Ecosystem Axis Management" would reinforce the processes, and their effectiveness together with overall management of MPAs in Korea should be evaluated by designing appropriate measurement tools.

A marine protected area (MPA) is a spatially designated section of the ocean where the biodiversity is high. Munseom MPA has a unique underwater landscape including soft coral, subtropical fish, and benthos, attracting many scuba divers. This paper intends to evaluate the willingness-to-pay (WTP) for the scuba diving management policy in the Munseom MPA. As a stated preference valuation method, a choice experiment was applied to assess divers' preferences with economic values for the policy. The attributes used in the study included zoning (temporal closure), conservation education, daily permit, soft coral area, and diving fee. We collected 333 questionnaires through online and field surveys and used 296 after excluding incomplete responses for the final data analysis. Study results show that a six-month closure, a decrease in soft coral habitat, and the diving fee were statistically significant. A positive coefficient with regard to the six-month closure variable indicates that divers preferred the policy, and the marginal willingness to pay (MWTP) was estimated to be KRW 8,637 per person per dive. The aggregate WTP of KRW 233 million was obtained by multiplying the MWTP by the number of visiting divers per year. When comparing the levels of recreation specialization, more skilled divers preferred the management option. The results of this study will help predict the priority of management measures and the levels of acceptability among divers when diving management is implemented in Korea in the future. This study suggests that marine environmental policies need to consider divers as one of the important stakeholders for marine conservation.

본 연구는 MPA 효과를 분석한 생물경제학적 연구로서 어업자원분포와 어종이동 특성에 따른 MPA 설치 전 후의 자원량과 어획량 변화를 이론적으로 분석하였다. 특히 본 연구에서는 어업자원분포 모형 가운데 폐쇄모형, 발생지-유입지 모형, 밀도종속적 모형을 대상으로 하였다. 각 모형에 대한 MPA 효과 분석에 있어서는 어획활동에 따른 경제적 효과도 함께 고려했을 뿐 아니라 다른 어획노력량 통제수단과의 병용효과도 함께 살펴보았다. 모든 모형 하에서 MPA 설치에 따라 전체 자원량이 증가하는 것으로 나타났지만, 폐쇄모형과 발생지-유입지 모형 하의 유입지에 대한 MPA 효과분석 결과 총어획량은 감소하였다. 발생지-유입지 모형에서의 발생지 그리고 밀도종속적 모형 하에서의 MPA 효과분석에서는 어종의 이동률, 자원량 수준 등에 따라 어획량이 증감하는 것으로 평가되었다. 특히, 자원이동률이 클수록, 자원량 수준이 높을수록 어획량 증대효과가 있는 것으로 분석되었다. 또한 어업비용 증가로 인해 어획가능구역에서의 어획노력량 증대에는 한계가 있는 것으로 나타났다. 그리고 다른 어획노력량 통제수단과 병용되었을 경우 전체적인 자원량 수준이 보다 크게 높아질 수 있는 것으로 평가되었다.

본 연구의 목적은 우리나라의 해양보호구역 제도를 개관하고 제도의 문제점을 도출한 후 해양보호구역의 효과적인 관리를 위한 대안을 제시하는 것이다. 연구결과, 우리나라에는 다양한 법률에 기인해 여러 형태의 해양보호구역이 존재하고 있으나 이를 통합적으로 관리할 수 있는 제도는 마련되지 못한 실정이며 보호구역내 유해행위의 규제에 대한 규정이 미흡하며 해양보호구역의 기능을 제대로 활용하지 못하는 것으로 나타났다. 이들 문제점을 해결하기 위한 방법으로 해양보호구역 지정 및 관리를 총괄하는 단일법률의 제정, 국가차원의 전담 관리기구 조직, 어업금지 해양보호구역 설정 및 해양보호구역 네트워크 구축 등 네 가지의 정책이 제안되었다.

Marine protected Areas(MPAs) are specially designated zones of the sea that are designed to secure operation of ecosystem function and to restore marine ecosystem to the original state by excluding all detrimental human activities. MPAs have been proposed in many countries as means of realizing sustainable fisheries and recently MPAs are newly receiving attention as precautionary measure for global warming and climate change. The purpose of this paper is to examine the possibility of MPAs as fisheries management tools through a wide range of literature analysis and to suggest necessity of fisheries purpose of MPAs in Korea. Establishment of marine protected area can accompany various economic benefits such as restoration of marine environment, preservation of habitats, promotion of marine tourism and so on. Especially, a lot of case studies suggested that MPAs may bring out benefits to the fishing industry as a result of enhanced stocks. Fisheries benefits of MPAs on targeted species include increased abundance, increased mean individual size and age, increased reproductive output, enhanced recruitment inside and outside refuge, maintenance of genetic diversity of stocks, and enhanced fishery yields in adjacent fishing grounds, so called spill-over. MPAs for ecosystem conservation and protection of coastal wetland have been applied appropriately and effectively, however, the Korean MPAs system is still detective due to absence of fisheries purpose MPAs. Finally, suggestions for Korean MPAs can be summarized as following four recommendations; to establish number of small-scale MPAs rather than few large MPAs, to designate island and its surrounding areas as reserve, to consider MPA design with stock enhancement program, and to undertake co-management with Eochon-Gye, the traditional coastal community in Korea.

We evaluated the status and problems of golf course developments in the southern coast of Korea. It's adjacent waters supports nursery and fishing grounds for commercially-important fisheries species, and various sites are designated and protected as marine protection area(MPA), fisheries reserve, or clean area(blue belt) for producing shellfish. We proposed key assessment items for environmental impact assessment(EIA) and checklists in selecting golf course locations. For the protected areas, we suggest that it is essential to limit golf course establishment while setting a minimal distance from the coast to secure a buffer zone for mitigating the environmental impacts. To efficiently utilize existing regional coastal management plans, it is necessary to diagnose how a golf course development will potentially modify geomorphology and scenery, amplify pollutant loads from non-point sources, and disrupt the functions of coastal ecosystem. Especially, continued monitoring and assesssing input loads of hazardous materials originating from agricultural chemicals should be obligatory. Finally, measures for improving the QA/QC analysis were discussed to enhance reliability of environmental data with respect to golf courses and adjacent coastal waters.

산호충류는 한국을 포함한 전 세계적으로 보호종으로 지정되어 있다. 특히 제주도 해역의 서귀포 문섬, 숲섬 및 범섬 일대가 쿠로시오 난류의 영향으로 조하대 암반기질에 다양한 부착생물이 서식하며, 특히 연산호, 돌산호 등이 군집을 이루고 있어 UNEP의 ICRI(International Coral Reef Initiative)에 이미 보고되었을 뿐만 아니라, 세계 해양보존 지역 위원회에서도 해양보호지역 (Marine Protected Area, MPA)으로 선포하여 보호하려는 계획을 세우고 있다. (중략)
