This article presents the case of fishers-based forest planting initiatives in Japan, which have been ongoing since 1988. Aside from traditional practices aimed at protecting existing coastal forests, fishers have begun to plant and raise trees at the watershed level to benefit fishery environments. This study highlights the development process and identifies factors contributing to the long-term commitment of the initiatives toward sustainable fisheries in Japan. From a historical perspective, three areas (Hokkaido, Miyagi/Iwate, and Kumamoto) pioneered the idea of ‘forest to fishery’ benefits at the national level. Since then, the number of initiatives has increased in response to national ceremony events, networking, and funding support, with 3779 initiatives starting between 1988 and 2017. The findings revealed that many hosting organizations planted deciduous tree species, aiming to ensure soil and nutrient enhancement. To sustain the initiatives, strategic efforts to build multi-level collaborative partnership were identified in terms of budget, human resources, and securing land for plantation. This article describes a Japanese model to develop a pathway for linking fisheries management to forestry at the watershed level.

Promoting energy conservation in university dormitories is challenging because student residents are typically charged a flat utility fee. One possibility to curb excessive energy use in the absence of monetary incentives is to highlight the environmental consequences of energy use. However, it is still largely unknown how these consequences should be communicated to effectively change people’s behavior. In the present study, we analyzed the effect of framing the environmental consequences of energy use in terms of losses versus gains on the air-conditioner use of student residents of a Japanese university dormitory. A total of 330 students were provided with stickers to attach to the air-conditioner remote control in their dormitory room during the winter term. The stickers conveyed that increasing the temperature will hurt the environment (loss frame), that reducing the temperature will protect the environment (gain frame), or that changing the temperature will affect the environment (neutral frame). Day-to-day variations in objective air-conditioner use data were analyzed as a function of experimental condition to examine the effect of message framing. The change in air-conditioner use from pre-intervention to intervention period did not differ between experimental groups and neither did the change from pre-intervention period to a period after the intervention.

Controlled experimentation is critical for understanding the causal determinants of pro-environmental behavior. However, the potential of experimental pro-environmental behavior research is limited by the difficulty to observe pro-environmental behavior under controlled conditions. The Pro-Environmental Behavior Task (PEBT) was developed to address this limitation by facilitating the experimental analysis of pro-environmental behavior in the laboratory. Previous studies in Belgian samples have already supported the validity of the PEBT as a procedure for the study of actual pro-environmental behavior. Here, we aimed for a cross-cultural replication of this finding in a sample of N = 103 Japanese college students. Along the lines of previous studies, we found PEBT choice behavior to be sensitive to within-subject manipulations of its behavioral costs and environmental benefits. This implies that participants take these consequences into account when choosing between PEBT options. In addition, we showed, for the first time, that such consequence effects can also be detected in a less powerful between-subjects design. These results support the generality of consequence effects on PEBT choice behavior as well as the validity and utility of the PEBT for use in samples from different cultural backgrounds.

The Eco-Home Diagnosis program was introduced to promote energy-saving actions in Japanese households. However, to date, no study has examined whether it contributes to actual energy reduction while evaluating psychological factors that lead to energy-saving actions by participants. Hence, this paper reports on a case study in Fukuoka Prefecture that evaluated these effects. The findings revealed that 33 participants performed 3.3 energy-saving actions on average. They opted primarily for curtailment actions, but these had a small impact on electricity use relative to efficiency actions, which require high initial costs. The analysis of factors determining participants’ energy-saving actions showed that, before the program, behavioral intentions were influenced by cost–benefit evaluations. However, this changed after the program: Their interest was raised by perceived effectiveness, and this was seen to be linked to their motivation and behavioral intentions. It is recommended that enhancement of the perceived effectiveness should be further considered during the diagnosis process, while more feedback by advisors is needed to keep participants aware of energy-saving actions. The program is likely to be more effective if it targets those who are planning to build or renovate their homes.

Urbanization requires expanding the necessary infrastructure for water and sanitation to make city water safer and keep the environment clean. Instead of stable water supply and drainage, the modernized water infrastructure development weakened the relationship between water and human, which has brought a shift from near water to far water-based lifestyle. In response to this, traditional wisdom which takes into account social-ecological system has been under-evaluated or ignored so that urban water management may become vulnerable due to their lower awareness to the water. With this recognition, this chapter presents a case of successful urban water management in Japan by describing the historical process of canal restoration in Yanagawa City. The case study highlights traditional water management which was linked to ‘near water’ while exploring the underlying causes of ‘far water’. The research provides insights into bridging the distances between near water and far water by creating ‘new near water’ in the urbanized world.

This chapter presents a case study of mangrove management and conservation in Aceh province, Sumatra island, Indonesia. It focuses on a traditional institution for coastal resource management (Panglima Laots) to govern mangrove resources while addressing mangrove rehabilitation and restoration programs after the Indian Ocean Tsunami. The case study revealed that rapid loss of mangrove forests in Aceh province had been experienced due to commercial pressures as well as the Tsunami. In the former, Panglima Laots provided leadership in governing mangrove resources among the fishers, but did not contribute to prevent other stakeholders from engaging in its large-scale resource exploitation. In the latter, the Tsunami led to a momentum of numerous efforts made by a large number of supporting agencies to improve mangrove resources. However, elaboration had been put into practice to achieve the number of seedlings planted while many agencies took little account the survival rate after planting. Mangrove conservation requires long-term maintenance. Community participation is essential in maintaining the resources, but the reality was the situation where local residents were involved only as unskilled labor. The lessons learned from the case study provide insights on integrating existing Panglima Laots into the outside-driven mangrove conservation programs to foster sustainable management of mangrove resources.

This chapter presents a case of Thailand by highlighting the process and interaction of mangrove co-management among diverse stakeholders under the national and local contexts. Human activities caused alarming degradation of mangrove forests under the Thai state-control regime. Past failures of state management created the scope for mangrove co-management, mobilizing various stakeholders to promote mangrove conservation and management. The research identified three phases to highlight the reduction of mangrove forest vegetation related to anthropogenic pressures and adaptive responses to restore the forests, where more elaborations for mangrove rehabilitation and restoration have been done by the government authorities. The case studies from the local context indicated that local communities in collaboration with various stakeholders including the government authorities, NGOs, academics, schools, and private sectors started to be actively involved in mangrove conservation and management. The present situation in Thailand through case studies can be fallen into the category of “network” as heterogeneous stakeholders mobilized and shared their own resources and were committed to promote mangrove conservation. The lessons learned from both national and local contexts draw some implications about characteristics of mangrove co-management regime in Thailand.

This article aims to address fishery adaptation to tackle the commons dilemma by introducing the Padu system. The Padu system which is a gear-specific fishery with strict rules has survived to date, but the system has become vulnerable due to exogenous pressures as well as internal population growth. With this background, the research presents a case study of stake-seine fishery in Negombo Lagoon, Sri Lanka by highlighting the institutional mechanism of the Padu system. Findings revealed that the system has developed a nested structure of fishery governance among right holders. A role of the Roman Catholic Church served as a basis for interaction vertically across institutions from local to national, securing robust fishery institutions against entry of outsiders to the system. Furthermore, the fishery introduced a welfare scheme, contributing to the adherence to their own rules including entry rights to the system which control internal population growth. Based on these findings, this article provides several implications to sustainable fishery resources management through the Padu system.
