The commons concept has evolved in multiple ways after the publication of Ostrom’s seminal work in 1990, which emphasized the evolution of resource management institutions and the usefulness of self-governance. As we move into the 21^st century, one of the institutional transformations is catalyzed by the emergence of Information and Communication Technology (ICT) as a techno-economic paradigm shift and the epochal creation of a new online social structure. However, there is a lack of understanding about the impact of ICT on common resource management, particularly in urban settings, that is urban commons. This study presents a systematic literature review of ICT-enabled urban commons with particular attention to its application to climate-related issues such as climate mitigation/adaptation in order to improve our collective ability to leverage ICT for building a more sustainable and resilient city. A total of 66 pieces of literature were included in our qualitative synthesis. We analyzed the geographical, categorical, and climate relevance. Subsequently, we used the coupled infrastructure system framework as a system thinking approach to dissect distinct usefulness of ICT-enabled commons in the building of relationships between resource system, resource user, infrastructure, and infrastructure provider to tackle climate-related issues. Our findings identified three key contributions of ICT to innovate climate-resilient solutions: 1) to redefine role of resource user as co-producer, co-designer, and co-monitor; 2) to enable real-time data-driven urban planning; 3) to improve resource efficiency and effectiveness. In other words, in a time of insufficient and limited public resources, the public sector can leverage the power of technology to harness public support and engage non-traditional stakeholders to make cities more sustainable and resilient while allowing policy-making to be big data-driven to tackle new urban problems that cannot be otherwise uncovered without the aid of ICT. The results provide directions to rethink the city based on collective action to diversity modes to govern common resources.

<title>Abstract</title>This study develops a projection model of future population distribution on the basis of Japan’s current depopulation trend and applies this model to scenario analyses that assume population compactification and dispersion. The model enables a description of population migration at two levels. First, municipal populations are projected using the cohort-component method, and second, the spatial distribution of populations within municipalities is projected at a 500 m grid resolution with the use of the gravity model. Based on the Japanese depopulation context and the country’s National Spatial Strategy, the compact scenario predicts the formation of medium-scale regional urban areas (population centers located across Japan) and the concentration of people on high-density population areas within municipalities. Meanwhile, the dispersed scenario predicts the formation of more but smaller regional urban areas and the dispersion of the population to low-density areas. The simulated population distribution for 2050 reveals spatial change in population density and age structure, as well as an abundance of areas that were inhabited in 2015 but will be zero population areas by 2050. Overlay analysis of future land use maps and the simulated population distribution maps can contribute toward identifying areas where natural capital such as farmland and forest plantation should be managed but where there will be significant population loss by 2050.

<p>It is important to reflect the demands of citizens when creating a sustainable vision of the future society. In addition, it is necessary to implement specific activities to realize the vision of the future society. Therefore, the feasibility of the future social vision is also required.</p><p>In this study, as a part of the 2nd Takashima City Town Development Promotion Conference, which is an administrative project of Takashima City, Shiga Prefecture, a sustainable regional future social image that is feasible and highly acceptable to citizens was created through the practice of a workshop program. The purpose of this study is to extract the requirements for the creation of the future social image by examining the creation process.</p><p>As a result, the aspect of solving regional issues through the utilization of regional resources such as forest resources that are deeply related to the formation of the region is strongly recognized in the creation of the future social image desired by citizens. It was found that the future social vision using these local resources presupposes the formation of local communities with accumulated social capital as the basis of activities.</p>

© 2018, Springer Japan KK, part of Springer Nature. Scenario analysis is recognized as a useful tool for exploring future changes in the relationships between ecosystem services (ES) and human well-being. This analysis should be carried out not only by experts but also by relevant stakeholders such as the public. In this study, we investigated the preference of Japanese people toward natural and produced capital-based ES by distributing questionnaires to the public for exploring the direction of ES utilization in the future. Respondents with diverse backgrounds living in Tokyo and Nanao city in Ishikawa prefecture answered a series of questions about the extent to which they preferred natural or produced capital-based ES. As the general tendency of the results, the preferences for ES from the natural capitals were stronger than ES from produced capital. The trends varied, depending on the attributes of the respondents. The stronger preference for natural capital-based ES was possibly a positive indication that utilizing ES from the natural capitals was significantly beneficial for human well-being. The results were informative to understand public perception on key aspects of ES utilization scenarios, including their preferences for specific types of ES.

To expand the use of renewable energy, it is necessary to optimize energy production at a local level through an appropriate combination of different renewable energy resources. Additionally, the environmental impacts from the use of renewable resources must be considered from different perspectives. Thus, this study aims to develop a decision tool that evaluates and optimizes the renewable energy mix at a regional scale with regard to various environmental impacts. This tool was developed by creating a municipal energy database that includes five renewable energies (solar, wind, small- and medium-scale hydro, geothermal and biomass energy) and six evaluation indicators (proportion of developed renewable energy, economic balance, installed wind power, decrease in CO2 emissions, circulation rate of biomass resource, and impacted ecosystem area). Specifying different constraints in the model allowed investigation of the optimal renewable energy combination in a study area for two different scenarios, with the results highlighting the trade-offs between the scenarios. We also optimized the combination of different renewable energies for every municipality across Japan, while incorporating the natural conditions and varying demand structure. In conclusion, the tool developed in this study could support decision-making regarding the development of renewable energy resources. (C) 2016 Elsevier Ltd. All rights reserved.

&amp;nbsp;To introduce the renewable energy in regional communities, it is necessary to select a sustainable energy mix with low environmental impact from the complex viewpoints. The purpose of this study is to develop a tool to optimize and evaluate renewable energy composition in municipalities considering multiple environmental criteria. This tool was developed by creating a database of energy demand and renewable energy supply potential of all municipalities in Japan and designing functions as evaluators. The developed tool successfully calculated optimal solutions in scenarios with different constraints and objective functions, and demonstrated a trade-off between ecosystem conservation and economic benefit.
