Korea has recently constructed a number of renewable photovoltaic power plants in Jeolla province as an effort to provide environment-friendly energy. However, several problems appeared in the power plant locations because they were not appropriately chosen ignoring social-environmental perspectives. Consequently, locations of both currently existing photovoltaic power plants require an social and environmental evaluations. This study aims to provide appropriate photovoltaic power plants locations and evaluation of current photovoltaic power plants in Jeolla province. By presenting location analysis of photovoltaic power plants, this study would minimize environmental and social side effects regarding photovoltaic power plants. Kriging and Analytic Network Process (ANP) are applied as methodology. ANP generates correct weights in combining spatial data, so that the result would present optimal locations. In addition environmentally sensitive regions were excluded in the analysis process. The results show that South and West coastal areas have a number of appropriate locations for photovoltaic power plants. In addition, evaluating currently running photovoltaic power plant locations, total 23 out 81 are turned out to be inappropriately located. This study is expected to contribute avoiding social and environmental conflicts in photovoltaic power plant locations and present criteria in evaluating photovoltaic power plants.

Defining soil quality in scopes and applications is one of the prerequisite for the sustainable management of soil environment to orient researches, strategies and policies. However, definition of soil quality is controversial depending upon a viewpoint of soil science or soil environment. Soil quality can be, irrespective of the disciplines, defined as the capacity of a soil to function within ecosystem boundaries to sustain biological productivity, maintain environmental quality and promote plant and animal health. Common to all of the soil quality concepts can be summarized as the capacity of soil to function effectively at present and in the future. The OECD includes soil quality as one of the agri-environment indicators. This article intends to i) summarize the current soil quality research, and ii) provide information on protocol of soil quality assessment. A framework for soil quality was divided into three steps: indicator selection as minimum data set (MDS), scoring of the selected indicators, and integration of scores into soil quality index. Korean government suggested possible physical and chemical indicators such as bulk density and organic matter for paddy and upland soils to OECD. The framework of soil quality assessment is not yet implemented in Korea. Countries such as USA, Canada and New Zealand have constructed the framework on soil quality assessment and developed a user-friendly version of soil quality assessment tools to evaluate the integrated effects of various soil management practices. The protocol provided in this review might help policymakers, scientists, and administrators improve awareness about soil quality and understand the way of soil environment management.

가뭄으로 인해 발생할 수 있는 가장 심각한 피해는 용수 부족으로 인한 수자원 시스템의 용수공급 실패이며, 따라서 가뭄 위험도는 사용 가능한 용수의 부족과 관련하여 정량화되어야 한다. 이러한 맥락에서 수자원 시스템의 가뭄 위험도를 평가하기 위해 주로 신뢰도(reliability), 회복도(resiliency) 및 취약도(vulnerability)와 같은 세 가지 이수안전도 평가지표가 사용된다. 이러한 평가지표는 각각 용수공급 실패가 평균적으로 얼마나 자주 발생하는지, 얼마나 오래 지속되는지, 또한 어느 정도의 규모로 발생하는지를 위험도를 정량화하는 것으로, 용수공급 실패사상의 빈도, 지속기간 및 심도를 나타낸다. 본 연구에서 DRI(Drought Risk Index)는 신뢰도, 평가도 및 회복도의 가중평균값으로 정의되며, 이는 지속기간과 심도를 변수로 하는 이변량 가뭄빈도해석과 같은 변수를 공유한다. 본 연구에서는 두 가지 형태의 DRI 를 이용하여 지역 가뭄 위험도 평가 기준 산정 방안을 제시하였다. DRI_O(observed DRI)는 용수부족 시계열을 통해 산정된 공급실패 사상으로부터 산정되며, DRI_D(designed DRI)는 이변량 빈도해석을 통해 산정된 특정 지속기간을 갖는 확률가뭄심도로부터 계산된다. 기후변화 시나리오를 이용해 DRI_O 를 산정함으로써 미래의 이수안전도를 예측할 수 있으며, 이를 DRI_D 와 비교하여 지역의 용수부족으로 인한 가뭄 위험도를 산정하는 방법을 제안하였다. 또한 기존에는 주로 과거 최대 가뭄사상을 목표안전도로 설정하였으나 DRI_D 를 이용하여 보다 현실적인 목표안전도를 설정할 수 있다. 낙동강 권역의 10 개 중권역의 10 개 기후변화 시나리오를 대상으로 분석을 수행한 결과 병성천 유역과 형산강 유역이 각각 최저 및 최고 위험도를 갖는 것으로 분석되었으며, 지역 안전도 기준은 평균적으로 재현기간 5-20 년 사이의 범위를 갖는 것으로 나타났다.

The application contents, process, and its limitations are discussed for the setting of Korean legal guides & criteria for water cycle and ecological condition in development project of land use by thorough comparison and examination of prerequisites and credits of water cycle and soil+vegetation by USA's SITES (Sustainable Sites Initiative). In the case of SITES, due to the implementation procedure operated as a non-governmental independent assessment system by Green Business Certification, Inc, the natural condition of water cycle and soil-vegetation items-the key element of ecosystem services can be quantitatively assessed, well along with its legal and institutional guidelines and regulations. On the other hand, in the case of Korea, as a part of the national certification procedure for green building, the ecological area ratio system still have very limited role as an only amenity resource in the creation of artificial green spaces and insufficiency of management system for rain water. In conclusion, it was understood as an urgent situation in necessary for prompt establishment of site's sustainability certification system at the national level, based on management of water circulation and natural soil & vegetation in developed area with consideration of various land uses and types of development projects.

The concept of carrying capacity for bivalve culture of an area can be classified into four hierarchical categories, according to their level of complexity and scope, such as physical, production, ecological and social carrying capacity. Most scientific efforts to date have been directed towards modelling production carrying capacity and some of the resultant models have been used successfully. But, the modelling of ecological carrying capacity is still in its infancy, because it should consider the whole ecosystem and all culture activities. A more holistic approach is needed to determine the influence of bivalve aquaculture on the environment and ecological carrying capacity. As an alternative, we can use a set of ecological indicators which can show the environmental performance of bivalve farms and assess ecological carrying capacity. Clearance efficiency and filtration pressure indicators show the value of 0.331 and 0.203, respectively, and these indicators suggest that the present level of culture in GeojeHansan Bay is above the ecological carrying capacity of 0.05. Consequently, these indicators can provide a guidance on the present level of culture in regard to production and ecological carrying capacity in GeojeHansan Bay.

This study is a basic study to evaluate the ecological environment of Changwon City. The study site was 6 ecotourism districts in Changwon-si, and the ecotourism index was evaluated through direct visits and interviews with the person in charge through preliminary research and various literature data from June to July 2021. There are six ecotourism indicators: climate crisis, air quality improvement, water conservation, natural coexistence, citizen participation, and tourism resource management. When looking at the scores for the six ecotourism areas in Changwon, it received the highest score in the areas of natural coexistence and air quality improvement. However, the ecoregion received the lowest score in the water resource conservation category, indicating that the water resource conservation as a whole was weak. Next, tourism resource management, climate crisis, and citizen participation are at the same level in all regions. As a result of the evaluation through the low-carbon ecotourism index, the Changwon City low-carbon ecotourism certification system should first be operated as a measure to revitalize the ecotourism region. It is necessary to prepare a low-carbon ecotourism level for Changwon City. Second, it is very important to guide and promote ecotourism areas to revitalize ecotourism areas. Lastly, to operate a sustainable eco-environment area, it is necessary to operate using local governance above all else.

경제적 측면에서 본다면 에너지는 생산과 소비에서 매우 큰 비중을 차지함과 동시에 다른 유형의 상품과 대체 가능성이 높지 않다는 점에 그 중요성이 있다. 에너지시장에 대한 정부개입의 필요성은 자원의 고갈전망이 제시되고 두 차례 석유위기가 발발한 1970년대부터 등장하기 시작하였다. 이러한 일련의 인식변화는 에너지부문에 대해 다양한 형태의 정부개입이 시작되는 계기가 되었다. 에너지시스템에서 발견되는 이러한 일련의 시장실패는 정부개입의 정당성을 확고하게 하는 동시에 정책 운영 자체를 복잡하고 어렵하게 하는 요인이 되고 있다. 에너지정책의 운용이 어려운 이유는 에너지부문에서 발생하는 외부효과가 한 종류가 아니라는 점이다. 신재생에너지의 장점과 매력은 이처럼 복잡한 시장실패를 근본적으로 해결할 수 있다는 잠재력에 있다. 하지만 개발노력이 본격화 된지 30년이 넘었음에도 불구하고 2001년 현재 신재생에너지가 IEA 국가의 TPES에서 차지하는 비중은 5.53%에 불과하다. 다양한 장점에도 불구하고 신재생에너지 기술의 개발과 보급이 저조한 가장 큰 이유는 현재의 에너지시장 상황에서 기술의 경제성이 확보되지 않기 때문이다. 신재생에너지의 장점에 대한 강조와 개발의 필요성은 더 이상 정책의 핵심주제가 아니다. 현 시점에서 정책운영의 가장 큰 이슈는 기술개발과 보급에 대한 중장기적인 전략의 수립, 이른바 '정책의 효율성' 이다. 본 논문은 신재생에너지의 이용 전반에 걸쳐 등장하는 다양한 지속가능성 이슈를 살펴보고 국내 여건에 부합하는 기술개발 및 보급방안을 제시하고자 한다.
