This paper introduces a sustainability assessment method for the rapidly urbanizing Yangtze River Delta in China addressing the role of land use pattern. We first calculated the sustainability component scores of 16 cities in the area in 2000 and 2005. The results showed that socioeconomic and environmental conditions improved while the performance of resource-use degraded from 2000 to 2005. We then made a spatial analysis of land use change (LUC) using geographic information systems during 1990–2000. We found that diverse spatiotemporal transformation occurred among the cities and identified urban development cluster patterns and profiles based on development density. Finally, we examined the impact of LUC on sustainable urban development (SUD). Using regression techniques, we demonstrated that urbanization, infrastructure development, industrial structure and income significantly affected environmental performance and resource-use. These results suggest a moderate pace of LUC with steady economic growth being key to SUD.

We investigated local forest management practices in Osaka, Japan aiming to clarify mechanisms that hinder long-term, sustainable forestry operation by carrying out forest surveys and interview surveys. Because mountain districts in Japan now face declining and aging populations, forestry work has shifted to forest owners’ associations, with efficient forest management being required on an ad hoc basis as a result of the subsidy system. We found that the forest management plan for the study site utilized only one-seventh of the economic value of the forest, mainly due to the local forestry structure and an inefficient subsidy system that requires efficiency. The income yielded by timber undergoing such forest management and distribution processes is too low to permit forest owners to carry out sufficient forest cultivation. To effectively utilize the wood, a subsidy system that takes a long-term view and a timber market that puts an appropriate price on wood are needed. We argue that it is important to bolster the management position of the Japanese Forest Owners’ Associations for design an institutional scheme that enables to practice forestry management from a long-term perspective.

Growing numbers of promising visions of the future and scenarios that may lead toward building sustainable societies are being developed. At the same time, advanced technologies and research seeds that could increase the likelihood of achieving such visions are also being rigorously conceived. Even so, we face challenges and barriers in achieving these visions due to large gaps between individual technology seeds and shared visions. In this paper we propose a “vision-meso-seeds” model as a practical framework for addressing sustainability transition and demonstrate meso level research whose primary aim is to design a matching of promising seeds at the micro level and societal visions at the macro level, facilitating an achievement of the set visions with quantified targets. In particular we highlight the importance of matching various strategies and measures derived from the top-down (vision-oriented) approach and bottom-up (seeds-oriented) approach in the meso level research. We argue that the meso level research shall constitute one of the emerging core fields in sustainability science and suggest that accumulation of knowledge through case studies be needed to enhance and verify theory, specific methods and approach necessary for advancing the meso level research in the context of sustainability science.

We examined the existing practices of various media to ascertain the usability of information based on life cycle thinking (LCT) which can be key to changing consciousness and behavior of consumers towards pursuing a sustainable society. Such information has been provided to consumers in various forms in various places at various times. Nevertheless, a number of issues, such as understandability, selectability, reliability, transparency, and costs etc., must still be addressed before consumers will be able to use such information as guidelines for pro-environmental behaviors in their everyday life. Further, it is also of critical importance that the consumers can culture LCT by encouraging themselves to be actively engaged in the design and evaluation processes of the upstream of productions and in the entire product life cycle. Another crucial challenge is finding ways to connect LCT with, not just product selection or designing and manufacturing, but lifestyle transformation. We need to encourage ourselves and others to think about what a sustainable life really means.

This paper analyzes historical trends of academic research on the water environment in Japan over the past 50 years in relation to societal circumstances by looking into 1470 articles published in a Japanese domestic journal during 1961–2010. We examined three components of the individual articles to substantiate the trends including “Visions”, “Target Water”, and “Objects”. The database of these components was first constructed, and then statistically analyzed. Principal components analyses revealed two historical turning points of the research trends, in 1970 and in the mid-1990s, showing first a clear transition of the main concern from industrial pollution to eutrophication, and later, a transition to global environmental issues. We also demonstrate that Visions and Target Water gradually diversified during the past 50 years, indicating that although the research activity in the early periods focused on serious pollution issues, more recently, the scope of water environmental studies expanded to various other issues along with the improvement in the quality of the water environment. We argue that academic research activity in Japan was conducted in close association with public concern and global movements in a timely and sensitive manner. Such knowledge could also provide implications to other nations facing serious water pollution.

This paper demonstrates a case study to comprehensively understand Japanese rural society, proposing an integrated approach to visioning sustainable rural society in the context of developed countries. We first provided an overview of Japanese agricultural history and conducted interviews with individuals regarding their life histories in two peripheral research fields in Japan. We then analyzed these life histories and compared them with the macro trends of agricultural policy. In particular, our analyses shed light on the interactions between agricultural policies, individuals’ life and local resource endowments in rural areas. Specifically, human, natural and man-made capitals in Japanese rural society have changed in the way they are used while agricultural policies have exclusively focused on rice production. Based on the observation, we argue that Japanese policy might have hindered farmers’ efforts and attempts in the country’s periphery. We conclude that integrating macro analysis and field research facilitates the understanding of local resources and residents’ wellbeing for conceptualizing and approaching the future of farming villages.
