As the second most populous province in Cambodia, Battambang also exhibits an increasing number of urban poor areas. This research focuses on the economic situation of slum areas in Battambang and how people in slum areas are affected by climate change. This research report describes socioeconomics of people living in slum areas in 4 villages in Battambang City. An investigation will be made on motivation of moving to slum areas, access to water, access to sanitation, access to electricity, transport and delivery, access to health care, access to education, security of tenure, cost of living in slum, literacy, and access to finance. We also explore the policy of the public sector toward climate change in Cambodia.

This study aims to analyze the features of adaptation governance of local governments by applying a multi-level governance framework, and to draw policy implications. We analyzed changes in governance of 17 metropolitan cities/provinces, and 33 municipalities in terms of horizontal and vertical cooperation in the process of developing 'The Climate Change Adaptation Action Plan' and its implementation stage. The result shows that the plan contributed to the higher level of vertical cooperation between the central and the local governments to a certain extent, however, during the implementation stage, the level of the partnership decreased due to the absence of governance mechanism. These trends were statistically significant at the level of municipalities. The role of Korea Adaptation Center for Climate Change (KACCC) was also diminished after establishing the plan. The horizontal partnership level among the relevant departments of the local governments showed no significant change as the level was low even in the planning stage. Though Public-Private Partnership (PPP) has increased a bit, it was statistically significant only in the municipalities. Moreover, there was no governance mechanism for PPP or it did not work properly. Based on the results above, it is recommended that the effectiveness of the plans should be increased and support for climate change partnerships or forums at a local level that promotes adaptive capacity is needed. The role of metropolitan cities and provinces should be strengthened through building a multi-level partnership structure. Governance institutionalizing for monitoring and evaluation is also needed.

Decision making strategies should consider both adaptiveness and robustness in order to deal with two main characteristics of climate change: non-stationarity and deep uncertainty. Especially, robust strategies are different from traditional optimal strategies in the sense that they are satisfactory over a wider range of uncertainty and may act as a key when confronting climate change. In this study, a new framework named Robust Stochastic Dynamic Programming (R-SDP) is proposed, which couples previously developed robust optimization (RO) into the objective function and constraint of SDP. Two main approaches of RO, feasibility robustness and solution robustness, are considered in the optimization algorithm and consequently, three models to be tested are developed: conventional-SDP (CSDP), R-SDP-Feasibility (RSDP-F), and R-SDP-Solution (RSDP-S). The developed models were used to derive optimal monthly release rules in a single reservoir, and multiple simulations of the derived monthly policy under inflow scenarios with varying mean and standard deviations are undergone. Simulation results were then evaluated with a wide range of evaluation metrics from reliability, resiliency, vulnerability to additional robustness measures. Evaluation results were finally visualized with advanced visualization tools that are used in multi-objective robust decision making (MORDM) framework. As a result, RSDP-F and RSDP-S models yielded more risk averse, or conservative, results than the CSDP model, and a trade-off relationship between traditional and robustness metrics was discovered.

The ocean plays a vital role in the international carbon cycle, absorbing human-induced atmospheric carbon and preventing further atmospheric carbon accumulation. However, while the ocean had been considered a victim of climate change, it did not receive much attention as a solution for climate change in the major agenda of UNFCCC. Recently, a growing awareness that the ocean can provide numerous potentials to handle untapped issues to address the climate crisis has arisen, which has prompted discussions to strengthen ocean-based climate action. Since 2020, UNFCCC "Ocean and climate change dialogue" has been a forum to integrate and strengthen the ocean-climate nexus. This calls for integrating ocean action into climate action and the relevant sectors. In this regard, this study examined the background and international trends of ocean-based climate action and presented the author's perspective on the scope of content that such action should pursue and the direction to achieve it. In addition, this study identified tasks of the integrated approach and advancement of co-benefit as ways to strengthen ocean-based climate action, and it suggested domestic countermeasures for the Korean marine policy on climate change based on this.

Recently, Japan's Meteorological Research Institute presented the d4PDF database (Database for Policy Decision-Making for Future Climate Change, d4PDF) through large-scale climate ensemble simulations to overcome uncertainty arising from variability when the general circulation model represents extreme-scale precipitation. In this study, the change of precipitation characteristics between the historical and future climate conditions in the Yongdam-dam basin was analyzed using the d4PDF data. The result shows that annual mean precipitation and seasonal mean precipitation increased by more than 10% in future climate conditions. This study also performed an analysis on the change of the return period rainfall. The annual maximum daily rainfall was extracted for each climatic condition, and the rainfall with each return period was estimated. In this process, we represent the extreme-scale rainfall corresponding to a very long return period without any statistical model and method as the d4PDF provides rainfall data during 3,000 years for historical climate conditions and during 5,400 years for future climate conditions. The rainfall with a 50-year return period under future climate conditions exceeded the rainfall with a 100-year return period under historical climate conditions. Consequently, in future climate conditions, the magnitude of rainfall increased at the same return period and, the return period decreased at the same magnitude of rainfall. In this study, by using the d4PDF data, it was possible to analyze the change in extreme magnitude of rainfall.

Many aspects of climate have been observed to be increasingly volatile during the past several decades. Episodic climate change is not considered to be uncommon. However, there are substantial environmental, social, and economic impacts associated with climate variability that can be managed if the climate and its impacts are properly understood. Plants and natural communities exhibit several types of adaptive strategy to climate change. There is ample reason to relate increasingly erratic weather with a warming climate. Historic climate extremes, the adaptive mechanisms plants exhibit, and how people have (or have not) responded with strategically sound concepts and policy to facilitate a sustainable environmental ethic are reviewed with a vision of international needs and economic stability.

This paper aims to propose a policy for linking and utilizing spatial data for resilient spatial planning against disaster due to climate change by analyzing the current status of spatial data in the fields of urban planning, environmental planning and disaster prevention. To do so, spatial planning guidelines and the current status of utilizing spatial data in each field were identified by conducting a literature review and phone/face-to-face interviews with professionals and representatives of relevant institutions. As a result, the lists of spatial data were drawn up which can be utilized or linked with each other for developing an official spatial plan at a local government level. On the basis of these results, policy plans were proposed to link and utilize spatial data among urban planning, environmental planning and disaster prevention fields for climate change adaptation spatial planning.

Diverse improvement projects such as replacing street lamps with LED, street trees, etc are currently in progress in Korea to reduce greenhouse gas so as to cope with change in climate. However, the effect of climate change policy is not exactly analyzed, because exhaust quantity and absorption quantity of greenhouse gas of the target street lamp and street trees are not arranged as information. Thus, this study studied the method to systematically manage low carbon related information of urban facilities by using GIS. It was found that low carbon information of the urban facilities is necessary to exactly analyze effect of climate change policy and the method to calculate carbon exhaust quantity and absorption quantity of each facilities should be established to build exact low carbon information of urban facilities. Further, it was found that the visualization of information related to low carbon of street lamp and street trees by using GIS easily and visually grasps and systematically controls the effect of policy coping with change in climate than the existing numeral data of exhaust quantity and absorption quantity of greenhouse gas.
