This study examines how the registration of certain agricultural regions affects the sales of vegetables classified as traditional. We focused on the sales trends of traditional vegetables from the Noto region, one of the first designated sites of Globally Important Agricultural Heritage Systems (GIAHS). We compared the sales of recognized traditional vegetables to those of similar traditional vegetables from nearby areas and vegetables labeled with the same place names as the traditional vegetables but without elements of traditionality in branding. The study analyzed the sale and relevant trends of four categories of vegetable: Kaga vegetables, vegetables labeled “Kaga”, Noto vegetables, and vegetables labeled “Noto”. We further analyzed the trends by applying Convention Theory to understand the underpinning “orders of worth” in the purchase and sale of the items. Both Noto vegetables and place-labeled vegetables increased in overall sales since GIAHS registration in 2011. The recent increases in sales volume and number of items, however, were largely due to the production of lettuce, a crop from a vegetable factory. By applying Convention Theory, we identified that in the agriculture of the region, industrial farming impacted even the GIAHS registered site. Thus, careful collection and analysis of evidence is necessary to evaluate the effects of GIAHS registration and draft an action plan for further evidence-based policy making.

Background: Bee honey is a main ingredient in traditional food culture in different regions of the world. Honey is widely utilized as an ethnic food item. Methods: This paper analyzes the historical and present status of beekeeping and honey production in Japan and South Korea based on the relevant literature and statistical data. Results: The findings reveal that Western honeybees are dominant in the two countries for economic and physical reasons. Honey production has declined and the amount of imported honey has increased in Japan and South Korea. The domestic and global honey markets closely influence reciprocally. Furthermore, urban beekeeping has emerged in these two countries as a hobby and an industry; it contributes to producing domestic honey and enhances the quality of the environment. Conclusion: To ensure sustainable forestry and conserve biodiversity, native beekeeping is necessary. This paper provides insight into beekeeping and honey production in Japan and South Korea.

Application of biomimetics has expanded progressively to other fields in recent years, including urban and architectural design, scaling up from materials to a larger scale. Besides its contribution to design and functionality through a long evolutionary process, the philosophy of biomimetics contributes to a sustainable society at the conceptual level. The aim of this review is to shed light on trends in the application of biomimetics to architectural and urban design, in order to identify potential issues and successes resulting from implementation. In the application of biomimetics to architectural design, parts of individual “organisms”, including their form and surface structure, are frequently mimicked, whereas in urban design, on a larger scale, biomimetics is applied to mimic whole ecosystems. The overall trends of the reviewed research indicate future research necessity in the field of on biomimetic application in architectural and urban design, including Biophilia and Material. As for the scale of the applications, the urban-scale research is limited and it is a promising research which can facilitate the social implementation of biomimetics. As for facilitating methods of applications, it is instrumental to utilize different types of knowledge, such as traditional knowledge, and providing scientific clarification of functions and systems based on reviews. Thus, interdisciplinary research is required additionally to reach such goals.

Blue carbon ecosystem (BCE) initiatives in the Coral Triangle Region (CTR) are increasing due to their amplified recognition in mitigating global climate change. Although transdisciplinary approaches in the “blue carbon” discourse and collaborative actions are gaining momentum in the international and national arenas, more work is still needed at the local level. The study pursues how BCE initiatives permeate through the local communities in the Philippines and Indonesia, as part of CTR. Using perception surveys, the coastal residents from Busuanga, Philippines, and Karimunjawa, Indonesia were interviewed on their awareness, utilization, perceived threats, and management strategies for BCEs. Potential factors affecting residents’ perceptions were explored using multivariate regression and correlation analyses. Also, a comparative analysis was done to determine distinctions and commonalities in perceptions as influenced by site-specific scenarios. Results show that, despite respondents presenting relatively high awareness of BCE services, levels of utilization are low with 42.9–92.9% and 23.4–85.1% respondents in Busuanga and Karimunjawa, respectively, not directly utilizing BCE resources. Regression analysis showed that respondents’ occupation significantly influenced their utilization rate and observed opposite correlations in Busuanga (positive) and Karimunjawa (negative). Perceived threats are found to be driven by personal experiences—occurrence of natural disasters in Busuanga whereas discerned anthropogenic activities (i.e., land-use conversion) in Karimunjawa. Meanwhile, recognized management strategies are influenced by the strong presence of relevant agencies like non-government and people’s organizations in Busuanga and the local government in Karimunjawa. These results can be translated as useful metrics in contextualizing and/or enhancing BCE management plans specifically in strategizing advocacy campaigns and engagement of local stakeholders across the CTR.

There has been an increasing effort to promote renewable energies as climate change mitigation measures in Japan. Yet, the installation of wind turbines and solar photovoltaic (PV) power plants is being contested in several parts of the country. There is a need to understand these oppositions to reduce the number of delayed projects or overcome future barriers. Thus, in this study, we investigated cases of opposition movements and legal proceedings against wind and solar PV power development. Results indicated that landscape elements and socio-ecological factors motivate local oppositions. For instance, there were cases filed due to landscape view obstruction caused by wind turbines and solar panels. In terms of socio-ecological barriers, examples of cases scrutinized showed opposition caused by the potential impact on recreational activities such as climbing and hiking trails. Additionally, we observed that there were differences in the scope and scale of opposition movements and legal proceedings between wind and solar PV power projects. These differences were related to the scale (project size) and duration (construction to operation) of the project coupled with the renewable energy-related legal system changes in Japan. We observed that the overall legislative framework is frequently designed at the national level while challenges in project site selection are dealt with at the municipal- and prefectural-level. The findings of this study can help policymakers to revise and/or develop legal systems that minimize impacts on landscape and social elements while satisfying the demand for renewable energy transitions.

Abstract Establishing a decision-making scheme for multiple land use types in a shrinking society is an urgent and persistent task. In particular, residents and governments face the complexity of cross-sectoral visions over concerned landscapes. This study examined the preference of residents for future visions and the effects of group deliberation in a Japanese rural community to enhance the current understanding of decision and learning processes on cross-sectoral land use types (i.e., agricultural land, forest land, and boundary areas) across ages and groups. This study posed the following questions: (i) what types of interactions do residents find among options on cross-sectoral land uses? and (ii) how do group deliberation influence the individual preferences of residents for land use? In the survey, the residents disclosed their preferences for the prepared visions over three land use types. The survey also enabled the comparison of choices before and after group deliberation. Regarding question (i), the residents’ choice prior to the deliberation demonstrated thematic coherence through land use categories. Smart technology and potential productivity improvement were selected across agriculture and forests. However, regarding question (ii), thematic coherence decreased after the group deliberation. The residents could communicate disagreements during group deliberation and consider the issues relatively independently over land use types, which separately views agriculture lands and forests. The choice after group discussions became increasingly embedded and influenced by residential areas and land ownership of residents. These findings provide unique insights into the group discussion on how individual decisions are affected. In summary, the preferences of cross-sectoral land use types did not converge but tended to diverge.

AbstractSeagrasses offer diverse ecosystem services, yet, they are among the most threatened ecosystems. When degraded or destroyed, their services are lost or reduced in the process, affecting, for instance, local communities directly dependent on their livelihood provision. The Intergovernmental Panel on Climate Change (IPCC) reported that climate change is projected to worsen over time; thus, there is an urgent need for mitigation strategies in practice and also in the longer term. This work aims to provide an alternative perspective of seagrass restoration as a nature based solution (NbS) on a global scale, yet, giving an emphasis on tropical regions such as Indonesia. We focused on seagrass restorations which are not yet well established in comparison with other restoration programs (e.g., mangroves) despite their critical roles. We present in this work how restoring seagrass meadows fits the global standard of NbS published by the International Union for Conservation of Nature (IUCN). The results of this study can serve as a basis for promoting seagrass restorations as NbS against climate change particularly in countries with a wide extent of seagrass coverage.

In 2019, Japan introduced a national forest-environment-transfer tax (FETT). Prefectural and municipal governments receive tax revenue. Currently, 37 prefectures in Japan have prefectural forest taxes, and the prefectures need to demarcate how their own taxes and the national tax are being used. This study analyzed the overall use trends of national tax, which is for supporting municipal forest management, and review the status of prefectural forest environmental taxes. National tax was primarily applied to organizing the information of forests and their owners. The main components of support by prefectures to municipalities were support to questionnaires for private forest owners, other technical supports, securing successors, and training successors. Regarding the prefectural taxes, forest types and policies, which were implemented by the taxes, were reviewed in 18 prefectures. The differentiation of the tax uses of prefectural tax and FETT as a national tax was implemented based on the types of forest and supporting activities, and the spatial scales of forest management. The formation of FETT does not necessarily accompany the flexible assignment of jurisdictions and functions of multi-level governance, with potentially limiting impacts so far. This study could concretely conclude with the demand for participatory social learning toward sustainable forest policymaking and implementations of payment for ecosystem services in forests at the multi-levels of the national government, prefectures, and municipalities.
