Forest managers are increasingly being challenged to produce goods and services to society while managing for ecosystem sustainability. Forest ecosystem management is an emerging philosophy to achieve these objectives. We synthesized some basic concepts of forest ecosystem, sustainability in forests and forest ecosystem management, and described the importances of long-term ecological studies. Also we presented few relatively simple principles of forest ecosystem management, strategies, and case studies for integrating forest ecosystem management principles into the forest management planning process. It was emphasizd that in forest ecosystem management process, society, land managers, forest managers, and scientists be entered into a partnership to reshape management goals, redefine objectives, and redirect management actions in response to changing socioeconomic information and evolving bioogical, physical, chemical, and environmental conditions. Agreement or disagreement with our synthesis and opinions on forest ecosystem management is out of the primary objective of this paper, which is to stimulate new and creative approaches to forest ecosystem management as an emerging issue in forestry.

The main purpose of this study is to suggest a way that how government innovation ecosystem can be successfully managed by applying neuro-cybernetics approach. Innovation ecosystem is not a rare phenomenon around us. Especially national innovation managed by government relies on heavily innovation ecosystem. Unfortunately discussions of successful management of this ecosystem are rare. This study strongly urged necessity of such management by observing the case of introduction of CDMA mobile communication technology in Korea. Neuro-cybernetics was suggested as one alternative approach for the such management.

The need and concern about ecosystem are growing rapidly. However, ecosystem management systems are still in the first stage since the data are handled locally and separately. It results in the waste of money and time. In this research, we designed and implemented ecosystem management system of stream region using geographical information system(GIS) that is able to be used to manage the natural resource efficiently. It is expected to be used as a useful tool for Improvement of environment and management of ecosystem as well as recovery of natural environment.

The potential of ecosystem-based fisheries management is recently recognized to be very important to improve the sustainability of fisheries resources. Under the depressed condition of many fisheries resources, this recognition has been expanded and more effort has been taken to improve this approach. Taking ecosystem concept includes the use of other tools of management in addition to fisheries regulation, such as stock and productivity enhancement, provision of physical structure, or marine protected areas. In the ecosystem-based fisheries management approach, it would require to holistically consider ecological interactions of target species with predators, competitors, and prey species, the effects of climate on fisheries ecology, the complex interactions between fishes and their habitat, and the effects of fishing on fish stocks and their ecosystem. Fisheries management based upon the understanding of these factors can prevent significant and potentially irreversible changes in marine ecosystems caused by fishing. A useful approach for analyzing tropho-dynamic interactions and mass-balance in marine ecosystems is introduced to demonstrate the complexity and usefulness of the ecosystem approach, which was applied to a small ecosystem in Korea. Korea should seriously consider to take the ecosystem-based approach to fisheries management, since most major fish stocks are currently depleted due to many reasons such as overfishing, land reclamation and coastal pollution.

The purpose of this study is to analyze causation of Ecosystem service's trade-off(ES trade-off) and to establish baseline data for wise spatial planning and management. In order to understand why and how ES trade-off occurs, systems thinking and causal loops were employed. The causal loop of ecosystem service creation cycle includes profits quantification process, decision making process, spatial planning and management process, and ecosystem services creation process. The profits quantification process has a limitation that all ecosystem service categories were not included in profits quantification, because quantification method for cultural services is insufficient. These problems led to unequal discussion opportunity in decision making process. ES trade-off occurs through transition of ecosystem function in spatial scale and temporal scale. In spatial scale, land-use variation and resource-use variation contribute to change an ecosystem function for different ES category by spatial planning and management. In temporal scale, a change of an ecosystem function for different ES category is influenced by ecological succession, seasonal change and land cover variation, which are parameter from environmental features. This study presented that spatial planning and management should ecosystem service assessment in order to enhance balanced ecosystem services.

해양과 연안 지역의 과도한 개발과 이용으로 인하여 해양생태계에 발생하는 문제들을 해결하기 위하여 많은 국가에서 해양생태계 관리계획을 수립하여 시행하고 있다. 본 연구에서는 네트워크 분석법을 적용하여 우리나라와 주요 해양 국가들의 해양생태계 관리 방향 및 특성을 분석하였다. 분석 결과 국내외 공통적으로 해양생태계 관리 기반 구축, 국제적 협력 및 파트너십 구축, 기후변화 대응 강화와 관련된 내용을 포함하고 있었으며, strengthen, promote, improve, establish 등의 단어가 많이 사용된 핵심어로 나타났다. 하지만 세부적인 관리계획에서는 다소 차이가 있는 것으로 나타났는데, 국외에서는 특정 종에 대한 관리계획의 제시와 이미 수행 중인 제도적 기반을 개선하는 단계인 반면, 국내의 경우 포괄적인 해양생물 관리 강화 및 해양생태계 관리를 위한 제도적 기반을 구축하는 단계임을 알 수 있었다. 본 연구는 국내·외 해양생태계 관리 방향을 이해하고 향후 국내 지역의 해양생태계 관리계획 수립 시 활용될 수 있을 것으로 기대된다.

An ecosystem-based fisheries management (EBFM) approach becomes more important as an alternative management method for a sustainable development of fisheries domestically and internationally. Many methods of applying a practical EBFM to fisheries management have been investigated, and considerable attention has been given to developing effective indicators of the present status of and changes in ecosystems and putting them to practical use. Among ecosystem indicators, developing socioeconomic indicators for EBFM is particularly important. This is because socioeconomic factors have direct effects on ecosystems, and ecosystems have direct effects on socioeconomic factors. Therefore, it is imperative that socioeconomic indicators are developed and evaluated in order to predict changes in ecosystems and to provide advice for effective fisheries management. This study is aimed to develop socioeconomic indicators which can be combined with biological and ecological indicators, in order to conduct the ecosystem-based fisheries assessment. In terms of socioeconomic indicators, five socioeconomic criteria were considered as important attributes of socioeconomic changes. These criteria include economical production, business conditions, income, market, and employment indicators. For evaluation of newly developed socioeconomic indicators, the Traffic Light System (TLS) method was used. In addition, on the basis of the application of developed indicators to the Korean large purse seine fishery, the socioeconomic conditions of the fishery and the usefulness of the indicators were evaluated and management implications were discussed.

Ecosystem-based fisheries management requires a holistic assessment of the status of fisheries by integrating fishery ecosystem indicators for management objectives. In this study four objectives were identified such as the maintenance of the sustainability, biodiversity and habitat quality and socio-economic benefits. The ecosystem-based fisheries assessment (EBFA) model to assess fisheries and their resources at the ecosystem level developed for Korean fisheries (Zhang et al., 2009) has a number of indicators for three management objectives. However, it was found that there were some overlapping components among indicators and that there were difficulties in assessing some indicators in the EBFA model. This study identified problems of the approach and suggested more pragmatic and simpler indicators. It also presented alternative reference points to assess indicators and discussed issues associated with the application of the EBFA model to a marine ranching ecosystem. In this study a total of 24 indicators were used for the assessment which included 4 socio-economic indicators. New indicators and reference points were demonstrated by applying it to the Uljin marine ranch.
