In Japan, fisheries’ product has decreased since the 1980s, and the government amended the fisheries law in 2020 to shift to managed fisheries. However, awareness of seafood sustainability is still low. This study identifies the reason for the low awareness and states the necessary actions to increase sustainable seafood consumption. The proactive stakeholders in seafood supply were surveyed to determine the current status of sustainable seafood sales. Marine Stewardship Council-certified fishers and MSC’s Chain-of-Custody certification holders answered the questionnaires. Fishers showed a positive attitude, citing proactive sales channel expansions and contributions to sustainability. Distributors were primarily passive, mainly because they obtained the certification at the request of their clients, and about half of them did not disseminate information between consumers and suppliers. Both fishers and distributors expect the government to promote campaigns and education. The stages of the awareness of producers, intermediary trade, and retailers are different and did not align. Therefore, if the supply chain stakeholders proactively educate themselves, choose sustainable products from the fishers, and pass the sustainability information to the consumers, sustainable seafood consumption would progress.

The Small Island Developing State, Cabo Verde, is one of the most important marine biodiverse hotspots in the North Atlantic. One of its national conservation strategies has been the declaration of protected areas, and currently, the country has 47 declared protected areas and only 26 have been fully implemented. The latest protected area, Baía do Inferno e Monte Angra Natural Park, is the first protected area proposed by a civil initiative, and the local people strongly support the declaration of this protected area. Therefore, this study aims to better understand the mechanisms behind strong local support, explore the lessons learned from this case and how it can help improve the implementation of other protected areas in Cabo Verde. We conducted 7 semi-structured interviews with previously identified community leaders and 480 questionnaires with the general population of the local communities. The results show that 78.6% of the questionnaire respondents chose co-management as the desired management model. We also found that non-governmental organizations and local leaders have played a crucial role in sharing knowledge with local populations and helping them to have a critical and informed view about the future implementation of the protected area.

Vulnerable sectors of the population living in poverty in developing countries are highly dependent on renewable natural resources for their livelihoods and daily lives. Sustainable resource management, improving the well-being of vulnerable people, and building resilience to shocks are global challenges. This study analyzed the outcomes of various autonomous innovations by the people themselves and the enablers of these innovations in the communities of developing countries. This analysis of 20 autonomous innovations from six countries revealed that these innovations produced outcomes that simultaneously improved multiple indicators of human well-being, including “basic materials for a good life”, “safety”, “health”, and “good social relations”. The process of promoting public values, such as education, health improvement, and landscape conservation as a by-product of collective actions was an important enabler of these innovations, as well as the innovator’s proactive attitude toward continuous improvement. Public values and supporting ecosystem services were emphasized from the early stages of collective actions, to realize synergies toward integrated natural resource management. It is also important to achieve conditions in which collective actions could be practiced autonomously and adaptively. These results revealed the great potential of autonomous innovations emerging among socially vulnerable groups and the important mechanisms for promoting autonomous innovations for the transformation of social-ecological systems toward sustainable futures.

Solving complex system challenges such as natural resource management in social-ecological systems (SESs) is fraught with great uncertainty. To cope with these challenges, socially vulnerable people in developing countries have created various autonomous innovations. This study focuses on the concept of leverage point (LP) to understand the emergence of innovations and the transformation mechanism of SESs. An LP is a part of a complex system where a small change can cause transformations in the entire system and can be identified from causal networks in an SES. This study analyzed the emergence processes of autonomous innovations as causal networks through transdisciplinary collaboration with innovators in communities and succeeded in visualizing the initial conditions, outcomes, and challenges. We constructed a new definition of LPs based on graph theory and classified LPs into three types based on their characteristics. The network analysis of the causal networks of two innovations in developing countries revealed that the three types of LPs functioned synthetically in complex systems to promote transformation. Based on these results, we propose the potential ways of interventions for the transformation of complex system networks including plural LPs and discuss their effectiveness as boundary objects in transdisciplinary processes collaborating with diverse stakeholders. Further research is expected to accumulate knowledge for solving the various challenges faced by SESs.

To address the complex and difficult challenges that are occurring in complex social-ecological systems, a transformation toward sustainable futures is required. Understanding the characteristics and functions of leverage points (LPs), which bring about significant changes in complex systems, will greatly contribute to the various practices toward achieving sustainable futures. We conducted a detailed analysis of 15 cases of autonomous innovations emerging among vulnerable sectors in six countries to contribute to understanding the mechanisms of transformation of social-ecological systems by identifying the characteristics and functions of LPs. We found that three types of LPs with different characteristics play their roles in a multi-layered and interrelated manner in the emergence processes of autonomous innovations. These LPs contributed to the improvement of various aspects of well-being and facilitated the transformation of the social-ecological systems by enhancing the five previously proposed enabler categories. The multi-layered and interrelated functioning of LPs promotes the enhancement of various aspects of human well-being and strengthens the enabler categories. These were found to be important mechanisms for the transformation of social-ecological systems. Based on these results, we derive nine guiding principles for the conditions and mechanisms of transformation. These results indicate that a deeper study of autonomous innovation through an LP lens could make a significant contribution to solving or mitigating the wicked problems faced by humanity.

Using a case of the Sekisei Lagoon, Okinawa Prefecture, the southeastern tip of Japanese archipelago, this chapter discussed the interrelationships among the sectoral policy interventions by various marine-related ministries, and the whole structure of the integrated ocean policy. First, we developed the Social-Ecological Systems (SES) Schematic, which summarized the main ecosystem structures, functions, use types, and the stakeholders relating to the Sekisei Lagoon. Then, sectoral policy interventions by various ministries were overlaid onto the SES schematic to graphically show their interrelationships. We found that the ecosystem structure and functions used by one sector is closely connected to other structures and functions, which are then used by other sectors. In other words, all the stakeholders in the social system are closely interlinked at the ecological system level. Secondly, all in all, sectoral policy interventions by various ministries are covering almost all part of the Sekisei Lagoon SES, and therefore, the total coordination of the sectoral policy interventions and the creation of the synergy effects are required. In this process, the cabinet office and the local government will play the important roles. Finally, this SES schematic can be used as a boundary object to facilitate the knowledge exchanges among various stakeholders including the policy makers, practitioners, and researchers, to share the common understandings of the current situation, and to cocreate the policy interventions for the sustainable uses of Sekisei Lagoon.
