  • Problems in regard of ecological stability of urban ecosystem ensue from climate change and urbanization. Particularly, urban ecological conditions are deteriorating both quantitatively and qualitatively to a great extent. The present study aims to assess the current condition of selected sites (i. e. urban green zones and parks) in terms of preset assessment components; to find out problems and relevant solutions to improve the quality and quantity of parks and green zones; and ultimately to suggest some measures applicable to coping with climate change as well as to securing the ecological attributes of urban green zones and parks. According to the findings of this study, from quantitative perspectives, ecological attributes and responsiveness to climate change are high on account of the large natural-soil area(80%). By contrast, from qualitative perspectives including the planting structure (1 layer: 47%), the percentage of bush area(17%), the connectivity with surrounding green zones (independent types: 44%), the wind paths considered (5.6%), the tree species with high carbon absorption rates (20%), water cycles (17%), energy (8%) and carbon storage capacities(61%), ecological attributes and responsiveness to climate change were found very low. These findings suggest that the ecological values of urban parks and green zones should be improved in the future by conserving their original forms, securing natural-soil grounds and employing multi-layered planting structures and water bodies, and that responsiveness to climate change should be enhanced by planting tree species with high carbon storage capacities and obtaining detention ponds. In sum, robust efforts should be exerted in the initial planning stages, and sustained, to apply the methodology of green-zone development along with securing ecological attributes and responsiveness to climate change.

  • 본 연구의 목적은 기후변화의 위기에 있어, 기독교교육이 생태학적 교육으로서 나아가야 할 방향을 모색해보는 데 있다. 기후변화가 보여주는 것은 불과 2-3도만 지구의 온도가 올라가도 생존이 불가능하다는 사실이다. 그러나 현재 우리의 모습은 삶을 변경하지 않는 한에서 기후변화의 위기를 염려하고 있다. 이를 위해 먼저 기후변화의 의미와 그 원인에 대해 살펴보았다. 인간중심주의적 세계관, 현대의 산업적, 과학기술적 성장, 그리고 소비지향적 사회구조 등을 그 원인으로 들 수 있는데, 인간중심주의적 세계관은 모든 것을 인간의 관점에서 정당화하며, 자연은 인간의 지배대상이나 하나의 도구로 간주해왔다. 또한 인간의 경제활동 규모가 커지면 커질수록 에너지 소비량은 증가하고, 이 증가에 따라 생태계 파괴의 위협도 증가한다. 개인의 소비증가와 풍요가 생태계 긴장을 가중시키는 것이다. 이러한 기후변화의 문제를 해결하기 위해서 성서 속의 창조를 통해 인간과 자연의 관계가 상생과 공존임을 규명하고, 안식의 원리를 통해 인간과 자연의 회복을 가져올 수 있으며, 성육신의 관점에서 세계를 하나님의 '몸'으로 이해하는 생태교육적 단초들을 발견하였다. 이 단초들을 토대로, 인간과 자연이 배려와 존중의 관계성을 가지는 생태적 패러다임으로의 전환, 창조영성의 회복, 청지기로서의 책임과 지구 차원의 연대를 이루어가기 위해 생태적 상상력의 함양을 제시함으로써 기독교 생태교육의 방향을 모색해보았다. 기후변화의 위기에 있어, 기독교의 생태교육적 단초들을 통한 기독교교육적 접근을 통해 지구의 회복이 이루어지고 책임적 존재로 다시금 설 수 있기를 기대해본다.

  • 본 연구에서는 홍수, 가뭄, 물관리 등 수자원 분야 취약성을 규준(criteria) 및 지표(indicators)를 활용하여 평가하는 방법을 제시하였다. 제시된 방법을 통해 전국 및 지역 단위의 취약성 평가를 실시하였다. 또한, 평가 규모별 적정 유역 크기에 대한 방안도 아울러 제시하였다. 수자원 취약성 평가에 이용한 규준은 크게 평가 대상지의 민감도, 기후에의 노출, 기후변화에 대한 적응력으로 분류할 수 있으며, 각 규준을 지표로 계량화 및 표준화하여 취약성 평가에 반영한다. 기후변화에 대한 수자원 분야의 취약성은 일반적으로 시간이 갈수록 증가하는 것으로 평가되었다. 평가 대상지의 유역 규모는 국가 차원의 취약성 평가는 대유역을 기준으로 설정하는 것이 유의하며, 지역 차원의 평가는 소유역을 기준이 적절함을 알 수 있었다.

  • Environmental crises caused by climate change and human-induced disturbances have become urgent challenges to the sustainability of human beings. These issues can be addressed based on a data-driven understanding and forecasting of ecosystem responses to environmental changes. In this study, we introduce a long-term ecological monitoring system in Korean Long-Term Ecological Research (KLTER), and a plan for the Korean Ecological Observatory Network (KEON). KLTER has been conducted since 2004 and has yielded valuable scientific results. However, the KLTER approach has limitations in data integration and coordinated observations. To overcome these limitations, we developed a KEON plan focused on multidisciplinary monitoring of the physiochemical, meteorological, and biological components of ecosystems to deepen process-based understanding of ecosystem functions and detect changes. KEON aims to answer nationwide and long-term ecological questions by using a standardized monitoring approach. We are preparing three types of observatories: two supersites depending on the climate-vegetation zones, three local sites depending on the ecosystem types, and two mobile deployment platforms to act on urgent ecological issues. The main observation topics were species diversity, population dynamics, biogeochemistry (carbon, methane, and water cycles), phenology, and remote sensing. We believe that KEON can address environmental challenges and play an important role in ecological observations through partnerships with international observatories.

  • Climate change is the biggest concern of the $21^{st}$ century. Greenhouse gas (GHG) emissions from various sectors are attracting attention as a cause of climate change. The DeNitrification-DeComposition (DNDC) model simulates GHG emissions from cropland. To study future GHG emissions using this simulation model, various factors that could change in future need to be considered. Because most problems are from the agricultural sector, DNDC would be unable to solve the factor-changing problem itself. Hence, it is necessary to link DNDC with separate models that simulate each element. Climate change is predicted to cause a variety of environmental disasters in the future, having a significant impact on the agricultural environment. In the process of human adaptation to environmental change, the distribution and management methods of farmland will also change greatly. In this study, we introduce some drawbacks of DNDC in considering future changes, and present other existing models that can rectify the same. We further propose some combinations with models and development sub-models.

  • The main goal of this paper is to suggest a new path to new ecological paradigm in social environmental education. The old paradigm of environmental education consists of two elements. The first element is emphasis on the seriousness and urgency of environmental problems while the second one is the presentation of concrete action programs as solutions of environmental problems. The missing point of this paradigm is the internal process of meaning construction of actors. Any kind of social action must be based on the meaning which the actors gives to their own action. Becoming an environmentally conscious actor, therefore, actor himself needs to interpret the world from the new perspective. In this paper, we call the change of worldview in the deepest sense 'conversion'. Ecological conversion means shift from anthropocentrism to ecocentrism. In the following sections, main characteristics of ecological world view are specified and some examples of ecological confessions which reveal ecological world view are presented. In this last section, 7 ways of lifestyle change which can facilitate ecological conversion are suggested: 1) trying to be alone for a while everyday; 2) making peaceful state of mind; 3) sharpening the 'green sensitivity'; 4) creating slow way of life; 5) choosing voluntary simplicity; 6)raising spirituality; 7) practicing sharing and caring. Social environmental education in the new ecological paradigm could be considered as a starting point towards a civilizational shift from the dominant materialist civilization to the post-material ecological civilization.

  • 본 연구에서는 Intergovernmental Panel on Climate Change(IPCC) 기후변화 시나리오 A2와 B1에 따른 산림분포 취약성을 평가하였다. 산림분포 취약성은 한국형 산림 생태계 분포 모델 Thermal Analogy Groups(TAG) 의 산림분포예측 방법과 Hydrology Thermal Analogy Groups(HyTAG)에서 정의한 식생유형을 이용하여 기후 변화에 따른 잠재 식물상(Plant Functional Type: PFT)의 분포 변화를 기후변화 민감성과 적응성으로 나누어 평가되었다. 그 결과, 산림분포가 취약한 지역의 면적은 A2 시나리오에서 전체 국토 면적의 30.78%, B1에서는 2.81%로 나타났다. 행정구역별 취약성 평가 결과는 부산이 A2 시나리오에서 가장 취약하고 대구가 B1 시나리오에서 가장 큰 취약성을 나타냈다. 미래 발전 방향에 따라서 상이하게 구축된 시나리오 별 산림 분포 취약성 결과는 앞으로 산림 분야 적응대책 수립에 중요한 자료로 이용될 것이다.
