Before the Conference of Parties (COP) 21 of the United Nations Framework Convention on Climate Change (UNFCCC) in 2015, most parties of UNFCCC had submitted their intended nationally determined contributions (INDCs) and to achieve their voluntary targets, some parties consider using international market mechanisms. As one of such mechanisms, Japan promoted its own bilateral mechanism called Joint Crediting Mechanism (JCM). In this study, feasibility studies and projects under JCM have been analyzed by project type, sector, country and region, which could provide some implications in designing Korea's future climate policy to achieve Korea's targets of 11.7% using international market mechanism in INDC. Since 2010, JCM has promoted 542 projects and feasibility studies in 44 countries according to the Institute for Global Environmental Strategies (IGES) database. Among 542 projects, about 80% were feasibility studies implying that JCM was more focused on project identification. However, current trends of JCM show that more projects will be soon implemented based on these feasibility studies. For sectoral categorization, projects were categorized into seven sectors-energy technology, energy efficiency, renewable energy, waste management, city, strategic planning and projects related to the country's efforts to reduce emissions from deforestation and forest degradation (REDD+). JCM projects were mitigation focused with more than 70% of projects were related to energy efficiency, renewable energy and energy technology. At the regional and country level, JCM is highly focused on Asia and especially, more than 100 projects were developed in Indonesia. Based on the analysis of JCM, in order to develop bilateral international mechanism for Korea, it is worthwhile to emphasize that Korea considers Asian countries as her partner. In addition, Korea may consider the collaboration with Multilateral Development Banks (MDBs) to implement projects identified by Korea and Asian partner countries. Furthermore, strategically, it is recommendable to develop jointly with Japan who has already capacity and networks with other Asian countries to mitigate GHG emissions. Such financial resources from MDBs and Japan may contribute to meet the 11.3% of GHG reduction target from abroad according to INDC of Korea.

본 연구는 대표적인 아고산식물인 동일속 식물 구상나무와 분비나무의 기후변화 민감성 평가에 목적이 있다. 이를 위해 종 분포 모형을 이용하여 현재 및 미래의 종 분포 확률을 예측하였고 기후변화 민감성 평가를 하였다. MTSS를 기준으로 예측된 잠재 분포지는 분비나무가 구상나무보다 감소율이 많았으며, 스칼라 민감도를 이용한 평가에서는 구상나무의 민감도가 분비나무보다 높았다. 본 연구와 같은 종 분포 모형을 이용한 연구에서는 위치자료 및 환경변수에 따라 종 분포 확률이 달라질 수 있으므로 연구 대상종의 생태 환경에 대한 면밀한 조사가 선결되어야 하며, 본 연구를 기초로 하여 국내에 적용 가능한 기후변화민감성 평가 방법이 개발된다면 기후변화와 생물 다양성 적응 정책의 중요한 의사결정 수단이 될 것으로 기대한다.

Climate change is strongly threatening the performance of agricultural reservoirs, which are instrumental in ensuring uninterrupted water supplies for rice cultivation in Korea. In this study, various performance indices were derived and overall sustainability of the 400 agricultural reservoirs was evaluated in the context of climate change trends during 1973-2017. Rice crop evapotranspiration, irrigation water requirements, runoff generation in the upstream watershed, and volumetric evaporation losses were plugged into a water balance model to simulate the reservoir operation during the study period. Resilience, reliability, and vulnerability are the three main indicators of reservoir performance, and these were combined into a single sustainability metric to define the overall system credibility. Historical climate data analysis confirmed that the country is facing a gradual warming shift, particularly in the central and southern agricultural regions. Although annual cumulative rainfall increased over the last 45 years, uneven monthly rainfall distribution during the dry and wet seasons also exacerbated the severity and frequency of droughts/floods. For approximately 85% of the selected reservoirs, the sustainability ranged between 0.35 to 0.77, and this range narrowed sharply with time, particularly for the reservoirs located in the western and southern coast regions. The study outcomes could help in developing the acceptable ranges of the performance indices and implementing appropriate policy and technical interventions for improving the sustainability of reservoirs with unacceptable ranges of the performance indices.

Addressing climate change necessitates evidence-based policies grounded in science. The use of forest biomass for energy production is based on a broad scientific consensus at the international level. However, some environmental groups in South Korea are opposing this system of energy production. Through this study, the authors aim to reduce unnecessary confusion and foster an atmosphere conducive to meaningful evidence-based policies. We have classified the issue into eight categories: biological carbon cycle, carbon debt, nature-based solutions, air emissions, cascading principles and sustainability certification, forest environmental impacts, climate change litigation, and the behavior of environmental groups and public perception. Consequently, the following key points were derived: (1) the actions of some environmental groups seem to follow a similar pattern to denialist behavior that denies climate change and climate science; (2) the quality of evidence for campaigns that oppose the use of forest biomass for energy production is low, with a tendency to overgeneralize information, high uncertainty, and difficulty in finding new claims.; (3) most of the public believes that forest biomass energy is necessary, and the governments of major countries are aware of its importance. Significantly, Forest biomass for energy is based on an overwhelming level of scientific consensus recognized internationally.

The Ministry of Environment will enforce air quality standards for $PM_{2.5}$ in 2015 because it affects human health as well as climate change and brings about other adverse effects. Until recently, even though a number of researches have reported $PM_{2.5}$ emissions according to sources, they have not precisely considered the emission factors correspondent to each source for emission estimation. For the sake of establishing $PM_{2.5}$ emission inventories, this study was undertaken using activity data of each source taken from CAPSS (Clean Air Policy Support System) multiplied by each emission factor of U.S. EPA Speciate or EEA CORINAIR. The 2008's total annual $PM_{2.5}$ emission (73.971 ton/yr) can be apportioned into five sources, such as fuel combustion facilities (62.2%), mobiles (33.8%), production processes (3.2%), fires (0.4%), and waste treatments (0.3%). The results show that fuel combustion facilities and mobiles are the predominant sources of $PM_{2.5}$, and they should be taken into great account in establishing $PM_{2.5}$ standards. In addition, it is necessary and urgent to develop effective measures for reduction of $PM_{2.5}$ emissions from those two main sources as well.

Global warming affects critical natural resources, one of which is the oceans that occupy 70% of the total cover of the earth. In other words, ocean warming is a subset of global warming which needs to be addressed urgently. Purple laver (pyropia spp.) is one of the most vulnerable items to climate change although it is a major export product of Korean fisheries. The purpose of this study is to analyze the causality of how climate change caused by global warming affects the increase or decrease of PLP (purple laver production). The target area for analysis was set to Maro-hae between Jindo-gun and Haenam-gun. We selected marine environmental factors and meteorologic factors that could affect PLP as variables, as well as co-integration tests to determine long-term balance, and the Granger causticity tests. As a result, PLP and marine environmental factors WT (water temperature), pH, and DO confirmed that long-term equilibrium relationships were established, respectively. However, there is only causality with WT and it is confirmed that there is only a correlation between pH and DO (dissolved oxygen). There was no long-term equilibrium relationship between PLP and HDD (heating degree days) and there is a causal effect that HDD affects PLP; however, it was less clear than that of WT. The relationship between PLP and RF (rainfall), WS (wind speed), SS (percentage of sunshine), and FF (farm facilities) was all balanced in the long term, and causality exists. Based on the results of the analysis, policy proposals were made.

본 논문은 세계화 기후변화시대에 지역 경쟁력에 영향을 미치는 요인을 추정하고, 요인들의 상대적 중요성을 분석하는 데 목적을 두었다. 2001~2010년 동안 16개 광역시 도의 균형 패널 데이터를 구축하여 패널분석을 수행하였다. 1인당 지역민총소득을 종속변수로 하고 경쟁력 기반요인, 경제적 생산요인, 기후변화 적응요인을 설명변수로 하는 패널모델을 구축하였다. 본 연구에서는 모델 1(전형적인 지역 경쟁력 모델)과 기후변화 적응요인을 추가시킨 모델 2를 비교하였다. 실증분석 결과 종속변수에 가장 영향력이 높은 요인으로는 지식기반산업 비율과 인적자본으로 나타났으며, 에너지 비효율성이 증가하면 지역 경쟁력이 감소하는 것으로 추정되었다. 또한 모델 1에 비해 모델 2에서는 지역의 개방성과 기술혁신자본의 영향력이 상대적으로 더 증가하는 것으로 나타났다. 본 연구 결과를 통해 향후 세계화 기후변화시대에 지역 경쟁력을 강화시키는데 필요한 정책적 시사점을 제공하였다.

Watershed area can be submerged due to constructions and management of dams, and these change can impact not only on ecosystem and environment of river basin area but also on local climate. This study is conducted to construct and classify climate zones of Andong Dam watershed where the area is submerged due to the construction of the dam. By applying Principal Components Analysis (PCA) and Getis-Ord $Gi^*$ statistics, three climate zones were classified for the result. Each zone was then analyzed and validated with climatic and geological features including topography, land cover, and forest type map. As a result of the analysis, there was a difference in temperature, elevation, precipitation and tree species distribution among the zones. Also, an analysis of land cover map showed that there were more agricultural land near Andong Reservoir. This study on the climatic classification is considered to be useful as the basis for decision-making or policy enforcement regarding ecosystem, environmental management or climate change response.

With the effectuation of United Nations Framework Convention on Climate Change(UNFCCC) and Kyoto Protocol in 2005, ever growing concern on the importance of overseas forestation is diffusing worldwide. However, fierce international competition to secure overseas forestation sites, inherent uncertainty in UNFCCC or overseas forestation projects, and imbalances among policies on overseas natural resources development make it difficult to realize Korean long-term overseas forestation objective to secure 1 million ha by 2050. In view of necessity of overseas forestation projects for sustainable forest management and securing sinks of carbon to mitigate climate change, various efforts to reform current Korean overseas forestation systems are required. This study suggests several alternatives to improve current Korean overseas forestation systems including expanding financial support for overseas forestation projects, cultivating overseas forestation experts, establishing official organization for overseas forestation, constructing effective support system for overseas forestation projects, fostering international cooperation in the field of forest resources, and so on. Many theoretical, empirical or policy-oriented studies on the influences of UNFCCC and countermeasures on it in various Korean industries should follow this study.
