  • 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.

  • The purpose of this study is to explore the direction that Christian education should take as an ecological education in the crisis of climate change. What climate change shows is that it is impossible to survive even if the Earth's temperature rises by only 2-3 degrees. However, our current appearance is concerned about the crisis of climate change as long as we do not change our lives. First, the meaning of climate change and its causes were examined. The anthropocentric worldview, modern industrial, scientific and technological growth, and consumption-oriented social structure can be cited as the causes. An anthropocentric worldview justifies everything from the human point of view, and nature is the subject of human domination, but one regarded as a tool. In addition, as the scale of human economic activity increases, energy consumption increases, and the threat of ecosystem destruction increases with the increase in energy consumption. Individual affluence and increased consumption are exacerbating ecosystem tensions. In order to solve the problem of climate change, ecological education clues were found in the Bible. Through creation, the relationship between humans and nature was identified as coexistence and coexistence. Through the principle of sabbath, it is possible to bring about the restoration of humans and nature, and from the point of view of the incarnation, the world was understood as the 'body' of God. Based on these clues, the direction of Christian ecological education was explored by suggesting a transition to an ecological paradigm, restoration of creative spirituality, and cultivation of ecological imagination. In the crisis of climate change, it is hoped that the recovery of the earth will take place and that we will be able to stand again as a responsible being through the Christian ecological educational approach.

  • In this study, vulnerability of water resources to climate change was assessed in terms of flood, drought and water management. Criteria and indicators were employed for assessing the vulnerability. The criteria used to assess the vulnerability was sensitivity of the study area, the exposure to climate and the adaptability to climate change. These criteria were quantified and standardized using corresponding indicators. Vulnerability of water resources to climate change is assessed to be generally increasing over time. The appropriate watershed scales are the large drainage basin for national level vulnerability assessment and the small drainage basin for local one.

  • 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.

  • This study was aiming at assessing the vulnerability of forest distribution by the A2 and B1 climate change scenarios of Intergovernmental Panel on Climate Change (IPCC). The vulnerability of forest distribution was assessed using its sensitivity and adaptation to climate change with the help of the simulations of Korean-specific forest distribution model, so-called the Thermal Analogy Group (TAG), and the Plant Functional Type (PFT) defined in the HyTAG (Hydrological and Thermal Analogy Groups) model. As a result, the vulnerable area occupied 30.78% and 2.81% of Korea in A2 and B1 scenario, respectively. When it comes to the administrative districts, Pusan in A2 and Daegu in B1 appeared the most vulnerable area. This study would be employed into preparation of adaptative measures for forest in future in terms of using climate change scenarios reflecting different future development conditions.
