    Haze pollution in Indonesia is a harmful environmental crisis in the southeast Asian region. This paper investigates the impact of fiscal capacity in the context of a mixed instrument on haze pollution. By considering fiscal capacity, this paper provides an empirical analysis whereby regulatory tax enforcement may coexist and may complement the environmental regulatory action. This paper shows that tax policy produces a significant deterrence impact, reducing hotspot development by 1.47%. Furthermore, this paper demonstrates that the transition policy to a green tax revenue system is useful for addressing haze pollution.

    In this study, we compared the effects of forest conservation under two types of national park governance, including attitudes towards local people in Indonesia. The rate of deforestation including primeval forests has remarkably increased in Bukit Barisan Selatan National Park, where large-scale illegal encroachment is recognized. Primeval forests were changed into coffee plantations. On the other hand, Gunung Halimun Salak National Park, where collaborative management with local communities is being promoted, shows relatively small change in the rate of deforestation. The results show that the effects of forest conservation depend on the difference of governance. Primeval forests have slightly declined in the core zones of both parks, and the effect of zoning is noticeable in both parks.

    We tried to decompose the fluctuation factors of energy-related CO2 emissions from four megacities in China (Beijing, Shanghai, Tianjin, Chongqing), as well as Tokyo, during the period from 2004 to 2014, by using Kaya-identity, and analyzed China's low-carbon and air pollution policies integrally. In conclusion: (1) Factors for boosting CO2 emissions were mainly economic factors, and the factors having pushed down mainly were lower energy intensity rapidly progressing since 2010, in addition to a decline in carbon intensity acting steadily since 2004. (2) Looking at the relationship with policies, the co-benefit of air pollution control (especially for SOx) was progressing low carbon before 2010, and the 4 cities have reached the 2020-target level of CO2/GDP by 2013. Since 2010 the total emission volumes of CO2 have slowed due to full-scale implementation of low carbon policy, and Beijing turned to a downward trend.

    21 attractions in Changchun Garden are classified into 3 groups according to the disposition features of architecture, hills and water. Large-scale buildings along the control axes were set as the centres of the space for the attractions with a sightseeing function. Attractions with a residential function tended to have regular courtyards and dispersive freetype layouts. Attractions with religious and political functions had independent courtyard spaces which integrate with the surrounding hills. The design of attractions with a sightseeing function was greatly influenced by Western gardening. Although the design of attractions with residential and religious functions generally followed traditional Chinese gardening, partial elements of Western gardening style were evident.

    This study is about street trees affecting the landscape appearance. By focusing on the improving effect on the landscape by street trees, I investigated whether the impression of a front viewer would change depending on the presence or absence of a scenery made of street trees and determined the optimal balance between street trees and buildings. The impression change in the case study of Shizuoka station, in particular, the southern exit Ishida Kaidou, was surveyed using the semantic differential method. As a result, the street trees not only showed well the eye-stop but also increased beauty, calmness, and bustle, thereby reducing the pressure effect. The optimal balance of street trees and buildings was found to be dependent on the building height.

    To minimize the impacts of climate change, there is a need to identify scientifically the risk and develop appropriate countermeasures. The three main components of climate change risk are “hazard”, “exposure”, and “vulnerability”. While scientific understanding of hazard and exposure has improved over the years, it is not clear how vulnerability should be assessed and how vulnerability indicators should be selected. This study reviews the past studies on vulnerability to climate change, focusing on its conceptual development and indicators. Finally, this study develops a scheme for selecting indicators of vulnerability to climate change. This scheme can contribute to develop adaptation measures.

    The possibility of small-scale biomass power generation project on satoyama fueled by forest thinning was examined. First, we calculated the income and expenditure for a smallscale biomass power generation project, and set targets for the quantity and price of the wood chips such that the project could continue. Next, we estimated the volume of forest resources and wood chips in the target research area via aerial photos. The results of the forest resource survey, the progress towards broad-leaved forests from coniferous forests and grasslands was observed. It was confirmed that the current profitability of a small-scale biomass power generation project would be low. However, factors such as improvements in wood chip production methods, and the expansion of project scope, were confirmed to make commercialization feasible.

    Deliberative democracy is gaining attention due to its potential to overcome complex social issues. For effective deliberation, it is important for participants to get information, understand the others and deepen their opinions. We analyzed the results of a questionnaire survey distributed before, during, and after a conducted next generation energy workshop and focused on the characteristics of the individual and the group on the factors that affect opinion change. The results indicate that opinion change is related to the degree of interest expressed in the issues, similar to what previous research suggests. However, the study at hand, which was conducted in Japan, further suggests that opinion change occurs not mainly through interactive participation, but rather by passive participation. Therefore, it is important to create favorable conditions, so that all participants can benefit from the discussion and participate in effective deliberation.

    This paper analyses an operation and an actual condition of legal system of Civic Green Spaces(CGS) and municipal ordinance system of Opened Green Spaces(OGS) opened to the public based-on contracts between landowners and municipalities. Main results are as follows: CGS is managed according to the law, and OGS is managed flexibly to contract such as acreage and location etc. Because future municipal policy of CGS is to accept applications when submitted, it becomes a task to search contracting lands in order to enlarge CGS. Though OGS can be expected to apply green space inapplicable to CGS, it becomes a task to evade contract cancellation risk that may occur due to flexibility of OGS system.

    The sky view factor measurements were conducted using fisheye lens camera, spherical camera, Google Street View, and Digital Surface Model (DSM). As a result, it was found that in addition to the conventional fisheye lens camera, the spherical camera, Google Street View, DSM can be practically used for the measurement of the sky view factor. In using Google Street View and DSM, it was necessary to confirm that the buildings and the land use at the time of measurement did not change. In the case of measurement in forest and on road with street trees, the ratio of the branches and leaves after binarization is the cause of the error, and attention is necessary for the proper selection of threshold value in binarization.

    We hypothesized that college students with techno-internet addiction disorder tendency tend to develop a more severe, new type of depressive tendency and experience decreased quality of life (QOL). Conversely, students who exhibit higher levels of empathetic internet usage tend to encourage each other, have a higher psychological resilience, and show a preference for exercising with others, all of which suppress this new type of depressive tendency and improve QOL. Longitudinal data collected by questionnaire surveys of university students in the information sciences were analyzed by structural equation modeling, and the results appeared to support our hypothesis. In order to prevent this new type of depressive tendency in the current information society, it is essential to reduce techno-internet addiction disorder tendency and promote both exercising with partners and psychological resilience.

    In Japan, promotion of wind farm projects has been considered as one of the key elements in terms of the energy security. Proponents has, however, been confronted with oppositions to their projects recently. So far, little is known about the solution of environmental disputes due to wind farm developments. In this study, the survey on newspaper articles and the questionnaire on those who were against the projects were conducted, and analyzed factors potentially leading to the dispute resolution. As a result, followings were clarified; physical plan modifications such as downsizing of the turbine, relocation of the site, were likely to be one of influential factors. Non-physical modifications such as conducting supplemental survey by the proponent, creating community benefits, the adoptive management would be effective to get agreements.

    In order to clarify recognition of climate change countermeasures and a carbon-free society, we conducted a questionnaire survey targeting university students in Japan, and analyzed 661 responses. The following findings were obtained: 1. Most respondents imagined daily personal actions as countermeasures, and they considered that the countermeasures were inconvenient and forced patience. 2. Those who thought that the countermeasures increased the quality of life tended to image a positive impact on the global environment and air. Those who considered that the countermeasures decreased the quality of life tended to image a negative effect on their own life. 3) The degree of support for policies and the practice of energy conservation measures are related not only to the degree of comprehension of the information related to climate change, but also to the positiveness of recognizing the influence of creating a carbon-free society.

    In this study, we ascertained roadside residents’ awareness of the area and its street trees based on the questionnaire for the residents in order to analyze the structure of factors influencing their commitment to the maintenance of street trees, using covariance structure analysis. The results revealed that awareness of “perception of the value of street trees” increases simultaneously with awareness of “perception of the value of the area”; thus, both have a strong, positive mutual influence. The structure is clarified as one whereby “commitment to the maintenance of street trees” is strongly influenced by “perception of the value of street trees,” whereas “awareness of the problem of street trees” is not strongly influenced by “perception of the value of street trees.” “Evaluation awareness of the management situation of street trees” and “recognition of the function served by street trees”are strongly influenced by “perception of the value of street trees.”

    In the case of unique environmental management system in Minamishinshu, we analyzed factors by which social innovation was accepted by society. We also analyzed the process by which social innovation was created using the theoretical framework of collaborative governance. As a result, it was found that entrepreneurs and companies that motivated community contribution worked together with the local administration, thereby creating and disseminating socially acceptable innovations. However, the creation of innovations through collaborative governance seen in this case requires outstanding human resources and large amounts of time, resources and expenses, so there are some uncertainties about its continuity.

    While a series of biological, environmental and ecological studies regarding ocean acidification is taking place at a shallow CO2 seep occurring in an offshore location of Shikine Island, Tokyo, Japan, we studied the human dimensions of the seep’s existence. In order to assess the resident’s recognition, we interviewed regular users of the area whose livelihoods were likely affected by the seep, i.e., fishermem and diving operators. While we found negative recognition by more than half of fishermen, a diving operator exhibited positive recognition. We further assessed visual components which contributed to the positive acceptance by analyzing photographic records. We found that bubble vents and sea turtles were the components unique to the seep area, and were used as tourism resources.

    Residents' associations are long-established foundations of support for local communities in Japan. However, with rapid urbanization and the changes in socioeconomic circumstances, these traditional organizational forms have been forced to change. In this research, we focused on 67 residents' associations in Tsukuba City, Ibaraki Prefecture and classified them into rural and urban types according to their socioeconomic characteristics and land utilization. We then clarified the characteristics of the activities engaged in by these two types of association by comparing their residents' association rules.

    To clarify the heat stress reduction and ultraviolet shading effect by awnings, measurements of thermal parameters and ultraviolet intensities with or without awnings were conducted at a kindergarten in Ageo, Saitama prefecture in August 2017. Based on the measured data, the universal thermal climate index (UTCI), the wet bulb globe temperature (WBGT), and UV Index were calculated. Following results were obtained. The awning lowered UTCI and WBGT by 4.9 ℃ and 3.3 ℃ respectively in clear weather with solar radiation of 1,000 W/m2. This heat stress reduction corresponds to lowering the risk category of heat disorder by one level. Meanwhile, the awning provided a space not requiring protection against ultraviolet rays.

    Recently, the dilution of our “connectedness to nature” has come to be regarded as a problem. This study aimed to reveal the general outline of the emotional experiences that arise from exposure to greenery. A questionnaire survey was conducted with 457 participants. We extracted frequent words from 384 passages of free description data about emotional experience and created a co-occurrence network using text mining software. The most frequent word was “flower,” the next was “see.” We extracted terms indicating active involvement such as “nurturing” flowers and “decorating” with flowers, as well as remote relationships such as “seeing” flowers, from the co-occurrence network. Further, we were able to grasp the differences in emotional experience according to gender and age group, by conducting gender-specific and age-specific analyses.

    To reveal favorable landscape of roadside trees from the perspective of pedestrians, the desirable ratio of two elements, branch spread (B) and sidewalk width (W), was discussed. Subjects were presented with pseudo images in which the branch spread was altered in five stages, B/W = 0.2 to 1.0, for Ginkgo biloba, Zelkova serrata, and Cinnamomum camphora. A questionnaire survey was conducted using the semantic differential method. By factor analysis, two factors, "comfortableness" and "sense of openness", were obtained. By partial correlation analysis of overall ratio scores of the pseudo images and scores of two factors, "comfortableness" was found to have a large influence on overall ratio scores. With respect to overall ratio scores, B/Ws of 0.6 to 1.0, 0.6 to 0.8, and 0.4 to 0.6 were determined to be the desirable ratio for G. biloba, Z. serrata and C. camphora, respectively.

    The Republic of Marshall Islands (RMI), a low lying small island developing states in the Pacific, has set conservation and sustainable use of marine resources as a priority policy objective and RMI adopted in September 2015 the Protected Area Network Act (PAN Act). 63 marine managed areas were established as of February 2017. However, neither management plans nor resource management councils are yet established. The questionnaire survey and interview results reveal that the stakeholders are not aware of the PAN Act, but they are willing to support the PAN Act implementation while they exhibited the mixed reactions to the proposition of fishing ban or reductions. To facilitate the effective implementation of the PAN Act, it is deemed as necessary to support stakeholders’ participation in the PAN Act implementation and collective actions by providing financial resources and technical guidance.
