    Mangroves, seagrasses, and salt marshes or collectively known as blue carbon ecosystems are gaining salience because of their essential roles in reducing the risks and impacts of climate change through carbon sequestration and other beneficial services. Despite this, they are globally declining because of their vulnerability to natural and anthropogenic disturbances. Similar trends are also observed in Busuanga Island, Palawan province in the Philippines, where blue carbon ecosystems along with other coastal environments are perceived to be threatened by a number of factors. To better understand the state changes of blue carbon ecosystems, we collected the drivers and pressures and their impact on the whole coastal ecosystem as well as existing management responses by interviewing 26 stakeholders representing community organizations, non-government organizations, and municipal level government units from two municipalities (Busuanga and Coron) in the island. We used the Drivers-Pressures-State-Impact-Response (DPSIR) framework to analyze the information gathered from the interviews. The results of this study show that lack of institutional capacities (indirect driver) is the leading factor that hinders the progress or efficacy of the management. Most pronounced pressures caused by direct drivers to blue carbon ecosystems include overexploitation and coastal developments. The responses collected in the interviews can be grouped into policies and implementation, capacity building development, welfare and livelihood development, ecosystems management, and tourism measures. The information gathered in this study can be used to improve or change existing responses into more precise and contextualized measures in addressing specific impacts observed in the local areas.

    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.

    Berau Regency in East Kalimantan has one of the intact seagrass ecosystems in Indonesia which is increasingly under pressure. Threats to this ecosystem mainly derives from anthropogenic activities such as land conversion and tourism activities, which can lead to ecosystem degradation and carbon emissions. This study explores the indirect and direct drivers by analyzing the locals' awareness of the benefits of seagrass ecosystem services through semi-structured interviews and a random sampling questionnaire in several areas in the Berau Regency, namely Derawan, Tanjung Batu, and Tanjung Redeb. Highlights of this research include evidence on occupation's correlation with resource utilization and awareness, with fishermen showing higher utilization of the seagrass ecosystem from the provisioning aspect and government employees having a high capacity for knowledge of various seagrass ecosystem services. Insight from this study provides further understanding on the influence of aspects such as resource utilization and the involvement of the local government, in regards to the local awareness of seagrass ecosystem. The role of fisherman and government can be critical to raise the awareness and to support the communities' efforts to manage the seagrass ecosystem.

    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.

    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.

    Development of organic agriculture has been sluggish in contemporary Japanese society. To better understand and capture the status of policy implementation in both urban and semirural areas, this study examined ordinance designated cities (ODCs) by reviewing tendencies and their interests in organic agricultural policies. In concrete, this study reviews the status, trends, interests, and barriers of organic agricultural policies in Japan. This study compared ODCs covering largely urban areas and those ODCs including semirural areas. The quantitative element of comparisons is based on the population and economic size and then on semirural and agricultural characteristics through cluster analysis. As a result, urban ODCs were more concerned about the policies close to consumption. ODCs including semirural areas were more concerned about the ones on production. There are also ODCs in between to show diverse characteristics in the policy implementations and interests. To take this difference into consideration, all types of the ODCs would need to implement the policies for promotion of organic agriculture in future. The results showed the rural-urban difference at the ODCs in the policy tendency through the financial support for certifications, education, and organizing a marché. Further policy supports, such as accumulation of market information, mutual-learning among ODCs, and the information on the policy effect on the environment, economy, and society, can potentially support efficiency of policy. The general low policy interests among the ODCs could be improved by emphasizing the needs of locally sensitive policy with the effective participation of concerned farmers and other stakeholders including consumers.

    This study aims to identify the influence of the socioeconomic attributes and environmental contexts of citizens’ residential areas on the access and use of green areas during the COVID-19 pandemic. The results can aid policymaking and facilitate the safe and unrestricted use of green areas during the pandemic. The access and use of green areas were analyzed using a survey conducted after the official COVID-19 emergency in Japan (16 April to 14 May, 2020). Visits to green areas during the pandemic have gained salience globally from multiple perspectives: health, planning, social justice, and equity. The results of this study demonstrated that socioeconomic factors influenced the frequency of visiting green areas. The factors further influenced the use of the three categories of green areas (parks, agricultural lands, and gardens). Environmental contexts, including the land use patterns in residential areas, also influenced the use of specific types of green areas. Thus, policies need to further facilitate visits to green areas by reflecting the socioeconomic attributes of residents and their households, including income, number of children, gender, and age, incorporating those who have less access and considering the spread of COVID-19 locally. Furthermore, policies for the use of specific green areas, including parks, agricultural lands, and gardens, need to take cognizance of the residents’ environmental contexts. Management of specific green areas, like agricultural lands, is required, and residents should be provided with opportunities to use these areas with measures to avoid infection.

    We explore Japanese forest landowners’ characteristics that affect the awareness of the boundaries of their forest lands. Such information can serve as foundational forest management information that will be used in decision making by future generations. We focus on the owners’ awareness of the forest boundaries and examine its relationship with the owners’ characteristics. This is one of the first studies covering all forest landowners and their awareness at the municipal level in Japan, focusing on a municipality’s forest landowners. The results of this study suggest that forest landowners who are young, women, non-members of forest landowners’ co-operative associations, and absent from the municipality tend to be unaware of their forests’ boundary lines, location, and land area.

    Empirical research on urban shrinkage is being conducted around the globe, since many countries are confronted with the phenomenon of shrinking cities. So far, the research on urban shrinkage has focused strongly on case studies, which is why we can benefit from a diverse and empirically rich knowledge base on the phenomenon and its regional manifestations. By bridging and comparing the European and Japanese academic discourse, we aim to identify the different recurring theories and key issues discussed under the umbrella term ‘urban shrinkage’ and strive to uncover blind spots of the debate. For this purpose, we conduct a qualitative meta-analysis of 100 empirical cases that are documented in the literature dealing with shrinking cities in the EU and Japan. This meta-analysis is based on comparative qualitative content analysis. It reveals a regionally differentiated pattern of various causes, effects and responses documented for shrinking cities in Western, Mediterranean and post-socialist EU countries and in Japan. Based on these findings, we offer an agenda for future research by suggesting an integrative perspective on the context-specific dynamics of urban shrinkage. We argue for an integrative understanding of shrinking cities in order to develop a valid knowledge base for evidence-based policy recommendations.

    © 2020 Elsevier Ltd Coastal communities, knowingly or otherwise, rely on seagrasses for their livelihood, recreation and food source, among other services. However, despite its importance, seagrasses are not receiving similar attentions with its adjacent ecosystems, the mangroves, and coral reefs. Because of their role in climate change mitigation, seagrasses along with mangroves and salt marshes (the blue carbon ecosystems) are gaining attention recently. This preliminary study investigates the perception of coastal communities in Eastern Samar, Philippines on seagrasses. The results of the survey show that there is a level of high awareness among respondents to seagrass ecosystem services. Despite that, however, utilization remains low. The level of awareness varies on the type of ecosystem service; for instance, locals have a high awareness of provisioning services while low awareness of cultural services. The survey also included the perceived threats to seagrasses, where damages caused by natural disturbances are identified as the most concerning threat. This may be due to the geographic location of the sites that are frequented by typhoons. The perception potentially indicates depleted resources brought about by mismanagement or overlooking this natural resource. The results provide a more contextualized understanding on how local communities are aware of and interacting with, or the lack thereof, seagrass ecosystems. This could aid local government units (LGUs) and conservation groups in the area to craft practicable and sustainable management plans and threat-specific solutions.

    © 2019 Elsevier Ltd For sustainability of a region, a holistic view is necessary to understand its dynamics and the conditions surrounding cities and beyond. Conservation activity indicators can be instrumental in this context, yet they can be simultaneously counterproductive in areas where intra-city sectionalisms exist. With regard to urban biodiversity, Singapore proposed an index to evaluate the biodiversity, ecosystem services, and governance specific for the cities. The index, known also as “City Biodiversity Index,” is currently applied worldwide. We analyzed the relationships between local biodiversity management in twenty populated cities in Japan and their social and ecological characteristics in order to identify the characteristics necessary for the smooth functioning of indicator-based management practices. As a result, cities with high percentages of built-up areas (with limited natural resources) tended to implement quantitative evaluations for biodiversity, although most of the twenty analyzed cities conducted participatory monitoring with stakeholder involvement. Furthermore, we identified that collaborations among different government sectors can be linked to certain ecological conditions; municipalities with relatively large amounts of forest land per capita (with many natural resources) tend to implement collaborations. Our findings suggest that indicator-based monitoring and management practices conducted through collaborations among different sectors are common challenges in municipal biodiversity management. Using the indicators could promote dealing with these challenges and contribute toward maintaining biodiversity in a wider range of regions.

    © 2019 A Geographical Indication (GI) is expected to facilitate agri-environmental management in agricultural landscapes. Currently, local products from small-scale farms and national branded products with a relatively large scale of production are being registered using GI schemes. Considering the relationships among GI products, their agricultural landscapes, and traditional ecological knowledge (TEK), as a GI case study, we examined small GI farms in Odate City, Akita Prefecture, Japan, which produce edible plants called Tonburi. This research explored the complex cause-effect relationship between TEK and landscapes and found that the TEK of Tonburi production influenced biological diversity and vice versa. The TEK and skills of small farmers were confined to the family members of each farmer and were not shared at the community level until GI registration. However, the farmers shared their TEK of sustainable agricultural landscape management through the process of GI registration. Through negotiation between local agricultural cooperatives and farmers, TEK was provided as a form of cultural capital and shared with new producers after GI registration. We concluded that enclosed TEK negatively affects production maintenance and landscape management in the long term. However, the GI registration process contributes to the sharing of TEK as a form of cultural capital among Tonburi farmers.

    © 2018 Korea Food Research Institute Background: The internal processes of geographical indications (GIs) by the applicants in rural specific regions primarily remain unexplored, although GIs can facilitate retention of long-term accumulated traditional knowledge in ethnic foods. This article sheds light on (1) analysis of phase-wise internal processes of GI registration and (2) examine relationships between the duration of application and perceived effects of GI registration in Northwestern Japan. GI in Japan is a comparatively a new system introduced in 2015. Methods: This article applied thematic analysis. The criteria for evaluating the gap of GI registration effects among the seven GI cases were descriptive and analytical with the information and data coming from official documents, questionnaire survey, and personal communications with key informants of the GI applicants. Qualitative information with quantitative data was also applied to visualize the complex internal GI registration processes and their effects. Results: This article identified that GI applicants who took a relatively long time to complete GI registration tended to perceive the relatively weak registration effects. Alternatively, GI applicants who took a relatively short time to complete their GI registration tended to evaluate the effects of the registration highly. For the preparation process, the most difficult phases for applications were drafting the application documents and long-term communication with a GI regulator. Conclusion: This article provides insights on the methods to uncover the complex, both ex-ante and ex-post, GI registration processes to reorganize current members of GI applicants and to fill the gaps and enhance the effects of GI registration.

    Background: Ecosystem services of pollinators have been gaining importance, as mentioned in the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services thematic report on pollination in 2016. Apart from wild bees, human interventions including apiculture can contribute to management of ecosystem services. Ecological and local knowledge of management is transmitted through various processes, varying in content and quality. Methods: We analyzed the processes of knowledge transmission, beekeeping productivity, and their interactions with each other. The study was conducted in the Nagano Prefecture, Japan, where the largest quantity of bee honey is produced nationally. Beekeeping knowledge in Nagano is transmitted through different information channels, including families, friends, and books. We categorized the beekeepers based on their information channels. The relationship between productivity of beekeeping and information channels was also analyzed. Results: It was identified that beekeepers who obtained their knowledge from their parents had relatively large number of bee colonies. Furthermore, we observed by interviews with them that they tended to understand the importance of ecological conditions for sustainable beekeeping. Conclusion: The results implied a challenge to open the knowledge transmission channels beyond families, potentially transforming the knowledge from tacit knowledge among limited members to an explicit manualized knowledge in an aging society.

    Background Traditional vegetables are produced and consumed throughout Japan. Individual vegetables, including Kyo vegetables and Kaga vegetables, are individually defined with their own criteria for history and quality standards and are registered in their respective regions. Several traditional vegetables are utilized as symbols of regional revitalization. For example, Kaga vegetables are tourist attractions, and Noto vegetables are promoted in the Noto region and were registered under the Globally Important Agricultural Heritage Systems (GIAHS). Methods We will review the distribution, public standards, and definitions of dento-yasai, traditional Japanese vegetables. Quantitative analysis on the status of the branding of traditional vegetables will be conducted. Results First, the ambiguity and distribution of traditional vegetables are demonstrated. Next, as a case study, the results of a quantitative analysis of Kaga vegetables and Noto vegetables are provided. Kaga vegetables have their own quality standards and definition, and producers have acknowledged the positive impact of the regional certification, GIAHS, on the amount sold. However, a social conflict has been caused by their standards and definition. On the other hand, Noto vegetables do not have a strict quality standard, and they were registered relatively recently. Because of their comparatively lax standard, producers could not acknowledge the positive impacts of GIAHS certification. Conclusion Origins of traditional Japanese vegetables and relationships with their regions have innumerable ambiguous points. The results of the analysis of two types of traditional vegetables show that quality standards and definitions strongly influence branding and brand management.

    The purpose of this paper is to analyze how different definitions and methods for delineating the spatial boundaries of cities have an impact on the values of city sustainability indicators. It is necessary to distinguish the inside of cities fromt he outside when calculating the values of sustainability indicators that assess the impacts of human activities within cities on areas beyond their boundaries. For this purpose, spatial boundaries of cities should be practically detected on the basis of a relevant definition of a city. Although no definition of a city is commonly shared among academic fields, three practical methods for identifying urban areas are available in remote sensing science. Those practical methods are based on population density, landcover, and night-time lights. These methods are correlated, but non-negligible differences exist in their determination of urban extents and urban population. Furthermore, critical and statistically significant differences in some urban environmental sustainability indicators result from the three different urban detection methods. For example, the average values of CO2 emissions per capita and PM10 concentration in citieswithmore than 1 million residents are significantly different among the definitions. When analyzing city sustainability indicators and disseminating the implication of the results, the values based on the different definitions should be simultaneously investigated. It is necessary to carefully choose a relevant definition to analyze sustainability indicators for policymaking. Otherwise, ineffective and inefficient policies will be developed.

    © 2017 Korea Food Research Institute 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.

    Background To reveal the level of recognition of regional and product certifications related to agriculture, an analysis of the official minutes of assemblies and the perceptions of tourists was conducted. This is one of the first attempts to combine analysis of residents and tourists at the product level (Geographical Indications, trademarks) and landscape level (registration under Food and Agricultural Organization [FAO] or United Nations Educational, Scientific and Cultural Organization [UNESCO]-related certification systems). Methods The research sites were Itoigawa and Sado, two municipalities in Niigata prefecture. The former is certified as a Global Geopark, and the latter as a National Geopark and Globally Important Agricultural Heritage System (GIAHS). The text-mining approach was conducted to analyze the official minutes of the municipal assemblies, and the questionnaire survey was conducted to identify the recognition of tourists on the certifications. Results The results of the analysis of assemblies and tourists provide issues and possibilities of the certification systems. Tourists' recognition of the GIAHS and its weighting in the assemblies are relatively low. Residents and tourists have different expectations for regional certification. Residents expect education, while tourists expect tourism. Conclusion It is necessary to evaluate the GIAHS's contribution to tourism and industry when municipalities and international organizations manage the GIAHS sites. Considering the gaps between residents and tourists and taking measures to resolve them can contribute to managing certificated areas by collaboration of stakeholders. Regarding products aimed at branding, consumers need to be informed about the GIAHS as a regional certification in addition to product certification to share the historical and environmental characteristics of agricultural products.

    © 2017 Korea Food Research Institute Background This study analyzed certifications at the regional/landscape level and at product level. We focused on Japanese sake and tea as local place-based luxury items related to ethnic foods and socio-ecological landscape. Methods Specifically, this research analyzed two materials: the minutes of local assemblies (both sake and tea) and sales-promotion pamphlet (of a sake brewery). The quantitative approach of text mining was experimentally applied to the two materials. The cases of both sake (Hakusan City) and tea (Kakegawa City) were selected from areas designated with three certifications; Globally Important Agricultural Heritage Systems (GIAHS) by the Food and Agriculture Organization (FAO), Biosphere Reserves (BR) under UNESCO's Man and the Biosphere Programme (MAB), and Geopark. The sake of Hakusan City is the product with geographical indication (GI), of the Hakusan Kikusake. Results As the product level certification, the GI of sake is used in the context of a promotional tool both at the municipality assembly and sake brewery dimension. Alternatively, regional certifications (Geopark and BR) are utilized with limited extent for sake promotion in Hakusan City. The regional certification of the GIAHS is utilized in context of promoting Japanese tea in Kakegawa City. The product is not registered as the GI, and this may have influenced the use of the GI. Conclusion These results imply that the place-based character remains at product level certification and is rather limited at landscape level. The product level certificate or the GI are used more frequently in the promotion of the place-based products than regional certifications. In order to further establish the placeness of the regions, certifications of landscape level need to be harmonized with the products that are produced in the landscape, using methods of place branding or story-telling.

    Background Geographical indications (GIs) are collective intellectual property rights that protect food and other products uniquely linked to the production area, local geophysical conditions, and traditions, namely, with the terroir. Thus, GIs can contribute to the transmission and retention of culinary heritages and historical production practices. Methods Based on an analysis of application documents, we compare the historical linkages of all the Japanese and Austrian GI products. Although more than half of the Japanese applications refer to historical roots in the 20th century, the median of the Austrian GI linkages is in the 17th century. To closely examine these GI linkages, and to better understand their relevance to current cultivation practices, we compared three Japanese cases with roots of diverging depth to the first Austrian GI regarding motivations, geographical and historical linkages, and current cultivation practices and governance. Results The comparison found that all four products refer to the historical roots of the product name, the product varieties, or cultivation techniques. However, deeper roots did not automatically translate into higher priorities of protecting these historical linkages. The four in-depth case studies found that historic provenance and traditional production methods, although prominently highlighted in the official GI documents of all four GIs, were eclipsed by commercial motivations for GI protection and/or current production practices. In the cases analyzed, we found some potential mismatches between GI historical claims in registration documents and actual GI cultivation and GI management practices. Conclusions We conclude that our four GI cases do not represent “museums of production” or overly fixed perceptions of history. However, the collective action of the producer group has resulted in dynamic local cultivation practices without restricting innovation. The GI status has rather resulted in the protection of local farmers' collective action and old varieties than in the protection of old production methods.

    Background In this paper, recognition of traditional agricultural products by the general public is presented and analyzed to explore the transgenerational aspects of traditional vegetables and their knowledge transfer. It is necessary to understand how the products are recognized by different generations and gender, in terms of retaining and branding the local products. Methods A questionnaire survey with random sampling was conducted to identify the recognition of traditional vegetables including the Kaga and Noto vegetables in Komatsu City, Ishikawa Prefecture. By understanding the degree of recognition, elaborating strategic plans for retention of traditional agricultural products and effective promotion of the products can be implemented. Results The results from 149 respondents indicate that there are differences of recognition depending on their gender or age. In particular, young people obtain information on traditional vegetables mainly from TV, whereas older people gain information from newspapers. Furthermore, more than half of the Kaga vegetables are better recognized among the older generation. Conclusion The analysis of this paper serves as the basis to capture the cultural importance, or to develop branding strategy as the results clarify the degree of recognition of residents and tourists from various generations. As the population has been aging, transmitting knowledge about the products to young people who have less knowledge is the urgent issue.

  • Shifting paradigms in ecosystem based approach : An case of forest fi re history in United States and the science policy interface of them

    香坂 玲, Huntsinger Lynn, Mori Akira, 内山 愉太

    We review the paradigm shifts from an expert-led planning approach to a moreadaptive and"open"process symbolized in the term"ecosystem approach"or"ecosystembasedapproach". This paradigm shift was caused in circumstances that expert-ledplanning did not perform effi ciently and various environmental problems were diffi cult tosolve without more open and adoptive approach. Yet, ecosystem approach has not beenestablished. For example, issues including participation of stakeholders remain. Role andsignifi cance of science policy interface was overlooked in the era of expert-led planning.It is necessary to elaborate the appropriate interface that make eff ective participationof stakeholders be possible. In this paper, the shift is illustrated and analyzed with theexample of historic perspective of the US forest fires. Implications for policy makingare drawn from the case how participatory approach can be accommodated with thescientific rigor. This historical analysis reveals that the current forests with frequentforest fires and strong drought stress in the US were formed in the contexts of theforest reserves mainly from early 20th century and the environmentalism includingprejudice on the pre-modern environmental managements. In recent years, synergies ofthe diff erent types of knowledges including traditional and indigenous knowledges areexplored. In this context, development of the methods for reflecting voices of variousstakeholders with those knowledges to environmental managements, and the methods toelaborate trust among the stakeholders are urgent issues.

    本論文は既存の都市評価指標との比較検討を通じて、筆者らが開発してきた都市のサステイナビリティ評価指標(City Sustainability Index、CSI)の枠組みを提示する。既存の指標には歴史的背景の違いにより3つの系譜があるが、いずれも都市のサステイナビリティを評価する上での要件を明示していない。そこで(1)「強いサステイナビリティ」への立脚、(2)絶対評価と相対評価の区別、(3)都市の漏出効果の考慮、という3つの要件を明確化し、「制約指標」と「最大化指標」という二種類の指標を備えたCSIの概念枠組みについて論じる。これに基づいて構築したCSIのプロトタイプを用い、18のメガシティを対象にした評価結果を提示する。既存の指標と比較すると、CSIには地球環境と社会・経済的な公平性に関するサステイナビリティを絶対的に評価できる利点がある。一方、政策評価の枠組みが備わっていないという限界が明らかになり、この点について補完手法の開発が必要である。

    Purpose - Place-based foodstuffs have gained salience in markets worldwide and geographical indication (GI) products are prominent examples. The purpose of this paper is to focus on the governance (formal and informal institutions) of the European and Japanese GI schemes, discuss the variety of procedures of implementing the features of the governance system (inclusion and exclusion of actors) for six GI cases and reflect on future GI governance. Design/methodology/approach - The criteria for assessing the six cases were descriptive and analytical and the information and data come from official documents, literature (scientific and "grey"), interviews, observations and personal communications with key-informants of the GI systems. Three of the cases are categorized as "failures" and are included to provide more insights on the diverse dynamics of GI systems. Findings - Registration of GIs seems to be a process rather than a single step, requesting coordination and consensus and an interplay between internal and external actors. "Success" and "failure" are relative and related to self-governance processes and the openness of the social system of the GI to establish transparency on inclusion and exclusion. GI systems require constant management and re-definition of production quality or geographical boundaries to adapt to market, climate or technological change. Originality/value - The paper introduces GI systems categorized as "failures" (either products that did not register as GIs in the end or did register but failed to keep the registration) which provides more insights on how to design and manage complex GI systems.

    In the development of City Biodiversity Index (CBI) database, it was necessary to overcome technical challenges, including the collection of information for biological indicators. To overcome the lack of data, methods to utilize land-use data have been developed. For example, distribution and abundance of species correlate with the degree of land-use mix. The research site, the Hokuriku region of Japan, has a developed Satoyama, a socio-ecological production landscape based on mixed land use. A part of the region, Noto, has been designated as a Globally Important Agricultural Heritage Systems (GIAHS) site in 2011 by the Food and Agriculture Organization of the United Nations (FAO). We found it is necessary to consider the biological type in order to refer to land-use mix as an indicator of biodiversity because the diversity of some species had a negative correlation with degree of land-use mix. We also determined that some species were correlated with land use changes over time. By applying the methods developed in this study to other Monsoon Asian regions with rapid population increases, it might be possible to develop a database as a platform for sharing the findings and knowledge to implement the conservation of biodiversity under changing conditions of land use and human population size.

    Capturing the status, trends, and relationships in biodiversity and urbanization is a multi-dimensional challenge for scientists and policy-makers alike. An indicator, the City Biodiversity Index (CBI), was developed as a self-assessment tool to measure trends in urban contexts in three spheres: biodiversity, ecosystems, and governance. Its primary focus is "green," but it further encompasses social and economic aspects to measure the sustainability of a city. The indicators can be used to visualize trends and translate scientific assessments into policy. Since 2008, 25 cities voluntarily applied the CBI. In Asia, Japan applied certain components of the CBI to 665 municipalities in 2016 in one of the first large-scale applications at national level. Regarding data visualization methods, the city of Helsinki, for example, has a website to visualize environmental information on biodiversity. The aim of this paper is to identify the practical and scientific challenges in conservation of biodiversity in medium to small cities based on a questionnaire survey. The research site is Ishikawa prefecture, which comprises municipalities in the target sizes. The survey shows that certain terms were difficult to understand conceptually, particularly "ecosystem services." The lack of monitoring and available datasets posed a number of difficulties for applying the index to the majority of cities. A method to evaluate biodiversity and ecosystem services has not yet been established. These technical difficulties are complicated with administrative and financial issues as well as human resources, issues shared by the municipalities. Based on our survey results, recommended activities are discussed.

    Three island villages in the Okinawa prefecture, Izena, Iheya and Tokashiki, have introduced "environmental cooperative tax" to obtain the budget to conserve the landscape as tourism resources and to maintain their tourism facilities. In this paper, the current trend and process of the introduction of the environmental cooperative tax are investigated by reviewing the existing survey and statistical information. Further, the socio-economic characteristics of the 3 villages are examined in order to explore the possibilities of the applying the taxation to the other island municipalities. Overall purpose of this study is to rethink the tourism tax in the whole Okinawa prefecture and explore future direction of the tourism management in the Okinawa in terms of the tourism tax system. The revenues from the tax are stable in Izena and Iheya, increasing in Tokashiki. Izena has introduced the tax in year 2005 earlier than other two villages. By the introducing the tax, environmental conservation activities have been facilitated by the revenues of the tax in Izena. As the indirect effects of the taxation, environmental management activities by the residents have been reinforced in Izena. The tax introduced by the villages has characteristics as environmental tax and tourist tax, because the tax is used for environmental conservation and imposed on the residents and tourists who come from the outside of the villages. The population amounts in the 3 villages are relatively small in the Okinawa. By examining the demographic and economic structures of the 3 villages and the other islands municipalities in the Okinawa, similarity and uniqueness of the islands municipalities are identified. Based on the results, several municipalities which may have potentials to introduce the environmental cooperative tax are detected. The taxation can be a tool for the tourism management in the Okinawa by appropriate gainsharing and synergistic collaboration among municipalities.

    We analyzed cognitive values of the local residents by examining the correlation of the cognitive value and distances from the place of residence by respondents. The results are fromthe local residents who are frequently the main stakeholders for resource managements. The research site is Noto region in Ishikawa, Japan. We identified that tourism resources can be grouped into three categories: (i) the values of resources distributed along quadratic functions (U curve), (ii) those that decreased along negative linear functions, and (iii) those that did not have clear linear or nonlinear relationships between accessibility and their values. Moreover, impressions by residents in verbal terms were examined whether these impressions had correlation with the tourism resources. The typology and their linkage to impressions by residents in quantitative approaches provide us with unique perspectives for sustainable tourism management and destination management by combining of the different tourism resources.

    Background Under the influence of global trends, most regions are at risk of losing their local-food knowledge. In this context, analyzing the transmission of the knowledge, understanding the context of transmission, and implementing precise activities and policies are required. Noto is known for its unique ethnic fermented food products. Methods Through our questionnaire survey and analysis of the Noto peninsula, we explore the relationships between the attributes of local food producers and the variety of foods they produce, attempting to identify the key attributes related to making diverse local foods and the transmission of local food knowledge. Results Our analysis showed a correlation between the diversity of local foods made by residents and the number of years they had lived in the municipality. Conclusion The results implied that adequate management of social networks by local residents, who depend on the local environment, is required in transmitting the knowledge of local foods.

    Forest management approaches vary according to the needs of individual municipalities with unique geographic conditions and local social contexts. Accordingly, there are two types of subsidies: a unified national subsidy and a prefecture-level subsidy, mainly from forest environmental taxes. The latter is a local tax. Our focus is on examining forest management using these two types of taxes (i.e., central and prefecture-level) and their correlations with social and natural environmental factors. In this paper, we examine the spatial distribution of management areas using subsidies from the central government, the Forestry Agency of Japan, and prefectural forest environmental taxes in Ishikawa. In concrete terms, the spatial correlations of the management areas under two tax schemes are compared with the natural hazard areas (as a natural environmental factor) and areas with high aging rates (as a social factor). The results are tested to see whether the correlations of areas with the two factors are significant, to examine whether the taxes are used for areas with natural and social needs. From the result, positive correlations are identified between the distribution of management areas and natural hazard areas and between the distribution of management areas and areas with high aging rates.

    A City Biodiversity Index (CBI) has been proposed and applied at the international level to enable local municipalities and cities to manage biodiversity and ecosystem services in a sustainable manner. CBI databases are being constructed as global platforms, though the available dataset is limited. The land-use dataset is one of the datasets that can be utilized to apply the CBI on the national level in countries including Japan. To demonstrate the importance and potential of the CBI under the limitation of the available dataset, we attempted to apply the CBI to the 791 Japanese cities by using available land-use indicators, and categorized the cities based on the indicators. The focus of the CBI is self-assessment, but we propose that grouping of cities with similar profiles is possible and can serve as a basis for potential collaboration. Coordinating policies on various scales is necessary in order to enhance biodiversity on a global scale; one option is to increase collaboration among cities. As a result, we found three groups with similar characteristics amongst cities with forests, paddies, and croplands as major compositions in terms of biodiversity. These findings will contribute to policy formation and efficient information sharing for ecosystem services management.

    We have developed a visualized 3-D model of a City Sustainability Index (CSI) based on our original concept of city sustainability in which a sustainable city is defined as one that maximizes socio-economic benefits while meeting constraint conditions of the environment and socio-economic equity on a permanent basis. The CSI is based on constraint and maximization indicators. Constraint indicators assess whether a city meets the necessary minimum conditions for city sustainability. Maximization indicators measure the benefits that a city generates in socio-economic aspects. When used in the policy-making process, the choice of constraint indicators should be implemented using a top-down approach. In contrast, a bottom-up approach is more suitable for defining maximization indicators because this technique involves multiple stakeholders (in a transdisciplinary approach). Using different materials of various colors, shapes, sizes, we designed and constructed the visualized physical model of the CSI to help people evaluate and compare the performance of different cities in terms of sustainability. The visualized model of the CSI can convey complicated information in a simple and straightforward manner to diverse stakeholders so that the sustainability analysis can be understood intuitively by ordinary citizens as well as experts. Thus, the CSI model helps stakeholders to develop critical thinking about city sustainability and enables policymakers to make informed decisions for sustainability through a transdisciplinary approach.

    In environmental studies, different types of system boundaries are needed. Disaggregated GIS data are crucial because they can be flexibly converted into the target boundaries. The National Oceanic and Atmospheric Administration (NOAA) data of Gross Domestic Product (GDP) should be highly evaluated as a valuable GIS data. We, however, show the problem that GDP per capita in urban areas is lower than that in non-urban areas, based on the NOAA data of GDP. This is inconsistent with the fact derived from other relevant data. We discuss possible causes of the problem: continuous linear relationship between night-time lights and GDP leakage effects of night-time lights from urban areas to their peripheral non-urban areas excessive infrastructures in non-urban areas as compared with their economic output and bias in the allocation of estimated GDP data in informal sectors. We would rather contribute to the potential correction of the data than criticize the data in this paper. © Uchiyama and Mori.

Through the comparison of those in Tokyo, it reveals that: In central areas with high density, mostly informal settlements, the overcrowded problem might decrease but aging problem will increase. In some growing suburban areas, both the densification and the rise of elder population will be problematic, which would require adequate policy.

    一般にメガシティは人口規模によって定義されるが、人口規模は都市の一属性にすぎない。既往の研究において、人口規模が同規模のメガシティであっても、抱える問題は大きく異なることが示されている。それには、人口規模以外に多様な要因が考えられるが、都市が空間的な広がりを持っていることと関係があると思われる。メガシティの異なる空間特性を客観的に把握し、メガシティを空間特性により類型化することは、各都市の特性を把握し、その抱える問題や潜在的な可能性を考察する上で有用であると考えられる。本研究では、空間的な人口分布が都市の空間特性を一定程度示していると考え、人口分布特性によりメガシティの類型化を行った。その結果、対象35都市について、人口の特定の人口密度の地域への偏在傾向に関して四類型化でき、人口密度の異なる地域の空間的分布状況によっても四類型化できることがわかった。特に、最も複雑な人口分布特性を持つメガシティがアジアに集中していることが明らかとなった。各都市の空間特性を生かした将来に向けた再編を検討するにあたり、本研究の空間特性によるメガシティ類型を活用できると考えられる。

    2024年の森林環境税導入に先駆け,2019年度から森林環境譲与税の自治体に対する交付が開始される。国と市町村が主軸となる森林環境譲与税だが,実際には都道府県にも影響を及ぼす。第一に,森林環境譲与税は都道府県にも配分され,市町村の支援を促すよう制度設計されている。第二に,森林等の保全を目的とした37の府県の既存の超過課税との関係性が問われる。そこで本研究では,37府県を対象とし,質問票および聞き取り調査の結果を基に,森林環境譲与税導入の影響を分析する。特に導入前後での市町村への支援政策と組織形態の変化に着眼した。結果,市町村支援に関しては,「森林所有者の意向調査の支援」等に重点が置かれ,組織的な変化については,環境譲与税(と関連する経営管理制度等)の名目で担当者を増加させた府県が5割程度存在した。既存組織の名称の変更や,環境譲与税担当部署の新設も把握された。また,1県では条例レベルで県・環境税の使途の中身を改定していた。

    2018年に林産物として初めて岩手木炭,続いて浄法寺漆が地理的表示保護制度へ登録されている。いずれも生産地は概ね岩手県内であり,両者の地理的な条件は類似しているが,申請に際しての動機,論理の構築,直面した課題が異なる。類似した地理的条件下での産物の比較は,欧州と比較して歴史が浅い日本の地理的表示保護制度の知見と可能性を理解する題材となりうる。本稿では農産物とは異なる様相を呈する林産物領域における地理的表示の最新の展開と状況を報告し,同制度の特性である「保存・伝承」と「経済性」の二面性を分析する。具体的には岩手木炭と浄法寺漆の登録の過程と暫定的効果について調査を実施した。結果,申請要件となる産地・土地との結びつきと伝統性について,正当性を構築するための論理,根拠についての相違点と共通点が明らかとなった。同時に,登録の二種類の動機(保存・伝承,経済性)が各林産物ごとに混在しつつも双方の目的を担った地理的表示活用を目指していることが示唆された。

    The role of science policy interface in forest and biodiversity conservation is reviewed. Historically, the role of scientific knowledge was limited by the politics or the national-interests-driven international negotiation process such as the United Nations Conference on Environment and Development or the Convention of Biological Diversity (CBD) (Kohsaka, 2008; Koetz, 2008). To overcome such difficulties, intergovernmental science-policy platform on biodiversity and ecosystem services (IPBES) was established, similar to the structure of the (Intergovernmental Panel on Climate Change (IPCC). It is identified that IPBES differs from IPCC in that it reflects the nature of scale dependent nature of biodiversity and different knowledge systems including indigenous and local knowledges (ILK). Access and Benefiting Sharing (ABS) from the genetic resources is the key in sustainability.

    本研究は、地方都市における森林管理の実態と今後の管理に着目し、森林を所有するすべての住民に悉皆調査を行った。森林の持続可能な管理を行う上で重要な森林所有者の管理行動を規定している属性を特定することを目的とする。石川県小松市に森林を所有者から得られたデータを利用し、森林所有者を「職業の有無」、「在村不在村」、「森林組合加入の有無」「後継者の有無」を応答変数としてクロス集計表を用いた分析を行った。分析の結果、第一に有職の場合に森林の状態への認知が低くなることが認められた。第二に「在村不在村」は、森林への認知、管理行動の要因にならなかった。第三に、「森林組合加入の有無」においては、加入者は森林境界の認知が高い可能性があり、また今後の森林管理を業者への委託で行う傾向が認められた。最後に、「後継者の有無」においては、後継者の存在が、境界や面積などの認知について高める傾向があり、森林管理は自己で施行しており、今後も管理をしていくことを高める傾向が認められた。本研究では、森林所有者への悉皆調査により、森林の状態認知、維持管理、今後の管理に対して森林組合と後継者の存在の重要性が確認された。

    In this research, transmission of knowledge related to ecosystem services based on pollination is analyzed. Specifically, case studies and literature review of beekeeping in East Asian countries are conducted. Pollination is not only related to provisioning services of agricultural products, but also strongly related to other ecosystem services including cultural services. In this regard, beekeeping can contribute to management of ecosystem located in various lands including mountainous areas, agricultural fields, and urban areas. In East Asian countries, surrounding social conditions of beekeeping have differences, however, they have similarity in natural environment. Therefore, knowledge sharing for ecosystem management based on sustainable beekeeping can contribute to environmental management in the wider Asian region. This paper provides the results of literature review of transmission of knowledge related to beekeeping focusing on socio-cultural factors, and case studies in Japan.

  • 木材・産地ブランドと知財管理 地域団体商標への登録状況と地理的表示の展開

    香坂 玲, 川上 潤吾, 内山 愉太, 風 総一郎

    日本森林学会大会発表データベース, 2016年, 日本語, 特許庁が中心となり、地名を含む商標の登録の制度となる地域団体商標が2006年に発足している。2015年11月30日現在で野菜55品、水産食品45品、果実42品、木材・石炭・炭14品、米7品目などの586件が登録されている。 本研究では、仏壇などの加工品の木材製品を除いた「小国杉」、「北山杉」、「東濃桧」、「南部の木」、「吉野材」、「吉野杉」、「吉野桧」、「龍神材」を対象とし、その登録の動機、経済的・社会的影響、品質・地理区分の基準の有無、今後の展望について、申請をした森林組合に聞き取りを実施した。結果、動機と影響については、模造品の防止、近隣の産品の混同の防止、温泉など地域内の他の取り組みに触発など多様であった。ただし、狭義の価格向上など、経済的な利益は動機においても影響でも限定的であった。また北山杉を除き、生産基準について明確な取り決めはなされていない事例が大多数であった。 品質工程管理まで登録をする地理的表示の保護制度が農水省を中心に2015年6月に発足している。本研究対象の地域団体商標の事例のなかで、地理的表示の登録への動きは調査した事例ではなく、品質の基準と合わせて、今後の展開が注目される。
