    Research purpose and content

    Objectives and background

    Our aim in the LINKAGE project is to contribute to the realization of a resilient society in harmony with nature that can respond to climatological and socioeconomic changes while people in coral reef island systems in the tropical and subtropical regions of the western Pacific sustainably use the limited multiple resources of the islands, such as water resources, fisheries resources, and forest resources. To that end, the purpose of this research is to strengthen the adaptive governance of multiple resources, connected by the water cycle in coral reef islands.

    The islands that nurture the sea of rich coral reefs are widely distributed in the tropical and subtropical regions. Water is a very precious resource in coral reef islands, and the people who live in those areas have long used limited water resources such as groundwater and spring water with careful and innovative methods. As a resource, water is closely related to the people’s lives, but it also circulates while changing its form, and it also plays a role as a medium that links the land and sea. On islands, the scale of the water cycle that links the land and sea is small, and the coral reef ecosystem that nurtures the marine resources that provide sustenance to our lifestyles is also closely linked to the land through this water cycle. Such coral reef island systems have nurtured a diversity of endemic organisms and cultures. However, land use and socioeconomic changes in recent years have led to the depletion of water resources and the deterioration of water quality on islands, and these are also factors that cause the deterioration of coral reef ecosystems through the water cycle. The situation is also being exacerbated through the changes in precipitation patterns, sea level rise, ocean acidification, and rising sea temperatures that are associated with climate change. Adaptive governance of diverse resource use that can respond to climatological and socioeconomic changes is necessary in order for people living on coral reef islands to sustainably use the islands’ limited natural resources (multiple resources), such as the highly vulnerable water, fisheries, and forest resources.

    The specific objectives are as follows.

    1)    to clarify the linkage between the land and sea through the water cycle, and understand and predict multiple resource responses to climatological and socioeconomic changes, by using various stable isotopes, environmental tracers, and metagenomic analysis, 2) to clarify the linkage between organisms and culture nurtured in island life and their diversity, and elucidate the mechanisms that sustain the foundations of survival in resource-limited island communities, with a historical ecological approach, 3) to clarify the changes and multi-layered nature of the awareness and institutions that link local and global governance, by behavioral science and multi-level institutional analysis. Additionally, 4) for adaptive governance, we will consider the bridging of knowledge (scientific, regional, policy-based) as an important component, and we will visualize their relationships in order to attempt to create new values and integrate scientific and regional knowledge. Our aim through these achievements is to contribute to the realization of a resilient society that co-exists with nature in coral reef island systems that can respond to climate change and socioeconomic changes.

    How does the research contribute to the solution of the global environmental problems?

    The following three global environmental problems are targeted: 1) depletion and pollution of water resources,

    2) deterioration of coastal ecosystems related to the water cycle, and 3) decreases in coastal ecosystem services to society and economy. These global environmental problems are occurring in various regions around the world, but where these three problems are closely linked on a small scale are in tropical and subtropical coral reef island systems. Coral reefs form a complex and rich ecosystem that is comparable to tropical rainforests and habitat for diverse range of organisms, so they are useful as a resource for fishing and tourism, and they serve as the foundation that supports our livelihoods. Coral reefs cover only 0.1% of the Earth’s surface, but they have one of the highest number of species per unit area on Earth. Rich in biodiversity and sometimes called the “tropical forests of the sea”, coral reefs hold an important position as an element of the global environment. Based on the perspective of multiple resource adaptive governance in island societies, we position the coral reef island system, whose water cycle is fast, as a “field” where global environmental changes and human impacts are most likely to occur; and we link the latest scientific knowledge and traditional knowledge based on norms in order to explore how it can lead to behavioral change. We explore a new governance formation process that will be effective in fragile island regions regarding the use and management of water resources, including coastal areas. We conduct action research that collaborates with people in various sectors, in order to share academic research achievement with the local community. We anticipate that the analysis and exploration of the norm generation process that is needed for consensus building among stakeholders will contribute to solving global environmental problems.

     

    Methodology, structure and schedule

    The four units, namely the Natural System, Community Capability, Governance, and Knowledge Bridging Units consist the LINKAGE project. We adopt a variety of research methods used in the fields of natural sciences, humanities, and social sciences. Additionally, we will integrate this knowledge (data visualization), and actively engage in collaboration with society (e.g., action research, summer school, round table conferences), and develop the “Transdisciplinary research”, hereinafter referred to as ‘TD research’, aimed by RIHN.

    Based on the members’ research achievements and experience, as well as connections with the regions, we set the research targets as the islands of the Ryukyu Arc (Yoron Island, Okinawa Island, Tarama Island, Yaeyama/Sekisei Lagoon and so on), Palau Islands, and Wakatobi Islands in Indonesia. The diverse characteristics of these islands have been shown from analysis using various parameters such  as  topography and geological characteristics (high islands and low islands), state of existence of water resources,  characteristics of coastal ecosystems, existence of protected areas, differences  in  social  and  industrial structures, and differences in economic conditions. We take into account the characteristics of each island to conduct research while sorting out common and individual features.

    Expected results

    The LINKAGE project involves the development of TD research on multiple resource utilization and management (governance) in tropical and subtropical islands, including “water resources” and other important resources. The links between land and sea through the water cycle, links between biodiversity and culture, and multi-layered links such as consciousness and institutions, as well as the new knowledge that is discovered when they are integrated are hoped to lead to policy recommendations for the multifaceted options that are required for adaptive governance. We will also provide new knowledge about shifts in values and behavior toward the use of sustainable and renewable natural resources.

    For example, contributions to environmental policy can be made by scientifically constructing and visualizing material cycle simulations for terrestrial loads that integrate land and sea areas, if a specific target value for terrestrial loads could be determined based on a standard that does not exceed the threshold value of phosphate that is adsorbed and accumulated in seabed sediment.

    Additionally, the terrestrial load on Sekisei Lagoon is caused by animal husbandry, agriculture, sewage treatment, and so on. Kuroshima in Sekisei Lagoon has a thriving livestock industry, raising more than 2,800 beef cattle on the approximately 15-km2 area. It is currently essential to improve the problem of improperly treated livestock excrement. In the Natural System Unit, in light of the global depletion of phosphate rock and the global situation of chemical fertilizers, whose prices are rising daily, we came up with the idea of “development of coral- friendly self-sufficient compost fertilizer” that makes effective use of livestock excrement, whose disposal has become a problem. Products by mixing of CaCO3 that is made by fixing CO2 with livestock excrement can regulate the soil pH and promote the absorption of poorly soluble phosphorus by plants in strongly acidic soil. Realization of the developments and sale of “self-sufficient compost fertilizer” that is made from livestock excrement would lead to a reduction in the input of conventional chemical fertilizers, which run off significantly into the ocean; and also contribute to the creation of an environmental industry with new added value that contributes to carbon neutrality and reduced environmental impact.

     

    Project organization and membership

     The four units namely the Natural System, Community Capability, Governance, and Knowledge Bridging Units consist the LINKAGE project.

      In the Natural System Unit, we sought to comprehensively advance research related to land-sea linkages through the water cycle on islands by organizing researchers with diverse specialties such as hydrology, geology, geochemistry, paleoenvironment, coral reef ecology, biomineralization, and environmental genomics (Fig. 7). In particular, we added a young researcher who specialized in rearing experiments in order to investigate how terrigenous nutrients that accumulated in the seafloor sediment through groundwater in coral reef waters affect coral growth. This Unit emphasizes field research in which researchers from many fields

    participate as much as possible, and pay attention to improving the educational effects of multidisciplinary global environmental studies.

      In the Community Capability Unit, we established a research system with researchers related to arts and music, in particular local NPOs and community museums that have been active on the theme of the relationship between nature and people in the Ryukyu arc, and members with diverse backgrounds such as “non-researchers” such as local government officials and local researchers. Furthermore, Professor Sun Kee Hong of Mokpo National University in South Korea, a researcher on Asia-Pacific islands, will participate as a member, and in FY2021, he signed an MoU with RIHN. As mentioned above, this Unit is characterized by being composed with various specialties and experiences in addition to researchers.

      In the Governance Unit, we added a researcher who specializes in the conservation and management of World Heritage Sites and national parks as a member in order to advance World National Heritage research. We organized the Governance Unit with institutional analysis researchers and awareness survey researchers in order to study the relationship between local governance and global governance in coral reef island systems. Each researcher has research achievements in the fields of environmental governance, groundwater governance, nature reserves, biodiversity, tourism policy, and behavioral science.

      In the Knowledge Bridging Unit, we added human resources in order to examine effective and diverse communication methods and means for sharing the results of surveys and research with various entities and developing collaborative efforts (i.e., participatory action research). We also have local NPOs participating.

      In Indonesia, Halu Oleo University (HOU) and RIHN have signed an MoU, and surveys have been initiated with HOU researchers. An MoU was also concluded between the BAPPEDA (Regional Development Planning Board) Kabupaten Wakatobi Regency, and RIHN. Workshops are being held to share issues with LINKAGE, and a collaborative system is being built

     

    Challenges and achievements for this year

    Project overall progress

     

    As shown below, the overall progress of the LINKAGE project is advancing smoothly in FR1. This fiscal year, we hired two researchers (hydrology and ecology), one technical assistant (governance), and one promoter (administrative/public affairs).

     

     

    In this unit, with the overall aim of elucidating the linkage between land areas and coral reef ecosystems through the water cycle, we set as one of our objectives the construction of a land-sea integrated 3D material cycle simulation model that combines a 3D water cycle simulation model for land areas and a tidal current-material cycle simulation for sea areas. Therefore, we have conducted surveys on hydrology, aquatic environments, and coral reef ecosystems in domestic research target areas (Yoron Island, southern part of Okinawa Island, Tarama Island, and Sekisei Lagoon) in order to obtain the observation data necessary to build each model. A major achievement of this unit is the confirmation that land-derived phosphate flows into the sea through the water cycle and accumulates in the seabed sediment, inhibiting coral skeleton formation . Furthermore, we conducted a seabed sediment survey in Sekisei Lagoon and found that there was a negative correlation between accumulated phosphorus and coral density. This could serve as an indicator of terrestrial load in the sea. Additionally, we discovered that not only phosphorus but also heavy metals accumulate in the seabed sediment, which reduces the survival rate of juvenile corals. It has been indicated that the frequent large-scale bleaching of coral reefs in Sekisei Lagoon is caused by a decrease in the resilience of the coral reef ecosystem due to local terrestrial stress, and although monitoring has been ongoing for many years as part of the nature restoration and conservation project of the Ministry of the Environment, scientific evidence-based conservation measures have yet to be implemented. Based on the results revealed in the previous fiscal year, stating that “in Sekisei Lagoon, coral density was almost zero when phosphate (accumulated phosphorus) that adsorbed to the calcareous seabed sediment was 0.7µg/g or more”, improved coral coverage can be expected by setting the terrestrial load with this threshold as a target.

     

     

    In this unit, the issues to be addressed were organized into five categories. 1) How have biological resources been used (changes in livelihoods, social transformation, events)? 2) How do we perceive nature (folk knowledge, language, narrative, physical techniques, tools/folk implements, etc.)? 3) What role do human expressive activities in relation to nature play in the sustainability of society (nature views, traditions, songs, sketches, etc.)? 4) How were social adjustments regarding the use of nature made (social organization, morality, norms, resilience, etc.)?

    5) What supports a regional economic system (inter-island network analysis, moral economy, bartering, etc.)? The main activities conducted by this fiscal year are as follows:

    (1) Review of trends in biocultural diversity research. We conducted a survey of research trends, particularly in biocultural diversity research, to organize the research themes concerning the use of nature in island areas. We gave a presentation based on these results at the Social Hydrology Committee, Earth and Human Sphere Committee of the Science Council of Japan, and started discussions on the construction of “social hydrology”.

    (2) construction of biocultural diversity digital map. we promoted the construction of a participatory digital map of biocultural diversity that aggregates the results of research conducted in each region. (3) development of participatory community archive “Survey of old yunnu photographs of island nature and lifestyles”, as a collaborative survey with the local community and held in-person and digital exhibitions at Yoron Island. (4) development of communication tools: publication of the LINKAGE booklet series, which utilizes narratives and photographs collected from dialogues with local communities not only as primary materials, but also as tools for fostering new dialogues (priming water).

     

     

    The following three types of research have been advanced in order to clarify the relationship between local governance and global governance. 1) From the perspective of behavioral science, we conducted an awareness survey in Japan on nature reserves and the movement of people during the COVID-19 crisis. 2) From the perspective of institutional analysis, we advanced research on nature reserves, biocultural diversity, and tourism policies. 3) We advanced systematic reviews on adaptive governance and groundwater governance.

     

     

    The environmental education event “Mizunowa Laboratory Yoron” was started on Yoron Island. This event is an observation and study session on the theme of microatoll-core drilling that was conducted by the Natural System Unit for paleoenvironmental reconstruction of the surrounding sea area. A total of 14 people, ranging from elementary school students to adults, participated in the preliminary study session and the actual excavation observation session. This activity is a consistent part of the "knowledge bridging" the project ultimately aims to achieve. Although microatolls are familiar to locals, their characteristics and utility value are not well known. This event conveyed that the microatoll is an important natural resource that can record paleoenvironmental condition, and the event has contributed to the “creation of new value” in the region. The Yoron Town Board of Education focuses on “marine education” throughout elementary, junior high, and high school. It is thought that the approach in the form of linking with local concerns was a favorable one. In addition to members specializing in microatoll-core drilling, the event was attended by members with expertise in ecology and political science. The interaction between participants and multidisciplinary researchers at the event allowed them to exchange academic or local knowledge with each other, leading to results beyond expectation. Meanwhile, one issue we faced when implementing the event was the small number of applicants for the event. In the future, we will need to consider an effective recruitment method and timing that takes into account the attributes of the expected participants. Furthermore, the video redording of coral-core drilling was exhibited at the RIHN Open House this year. https://www.youtube.com/watch?v=7rbevxvrMcE&t=1s

    Amendments to research objectives, methodology and organization as applicable

    Governance Unit (GU): First, we started new research on human movement since the balancing of human movement and infection countermeasures during the COVID-19 crisis became an important issue for coral reef islands, which have limited resources. Second, we had planned to conduct an awareness survey in Indonesia, but we were unable to secure Indonesian research members (researchers turning down job offers), so we postponed the implementation of the survey in Indonesia. Third, we added a researcher specializing in tourism policy among our members to focus on research on the impact of tourism on coral reef islands. Fourth, we decided to conduct a systematic review of groundwater governance in addition to adaptive governance in order to develop a groundwater-focused discussion of land-sea linkages.

     

    Results achieved this year

     

    Natural System Unit (NU)

    We conducted the drilling of microatolls around Yoron Island to analyze the relationship between changes in human activities (population, land use, tourism, etc.) on the island and changes in coastal coral reef environments and ecosystems. We obtained a continuous core of good quality with skeletal annual rings of 30–100 years.

    Hydrological and aquatic environment surveys were ongoing on Yoron Island, southern part of Okinawa Island, Tarama Island, and Sekisei Lagoon (Kuroshima, etc.), and we improved the accuracy of a three- dimensional water cycle simulation model for land areas.

    In Kuroshima, located in Sekisei Lagoon, we conducted basic surveys for the assesszment of impacts on coral reef ecosystems (groundwater electrical survey, groundwater sampling, sampling of soil and livestock waste, and sediment sampling at seabed spring points (estimation of accumulated nutrient load).

    We established a method for estimating nitrogen loading sources using stable boron isotopes, and estimated the contribution ratio of chemical fertilizers and manures to nitrate nitrogen concentrations in groundwater.

    In addition to the Project Leader’s visits to Indonesia and the introduction of the LINKAGE project at an international symposium, a workshop was held with researchers from Halu Oleo University (HOU) and government officials from the Wakatobi Regency Development Bureau and Environment Bureau, where we shared issues and built a collaborative system.

     

    Community Capability Unit (CCU)

    Construction of foundation for biocultural diversity digital map: We organized a schedule and tasks for examination of a common survey form (biocultural diversity survey card for each high island and low island), data entry work, and construction of a community digital archive in which local people can participate.

    Modeling of participatory action research (public humanities): Currently, we are using the collected photographs to develop an educational program that considers the nature and culture of the island together with the Yoron Town Board of Education, school officials, and NPOs.

    Design of a place for dialogue through international workshops and a monthly “LINKAGE-CCU IDOBATA workshop”: we held a publication report meeting for the booklet series “Learning with the Islands” in Ishigaki City and discussed the potential of rice paddy education as a place to think about the relationship between nature and humans. Additionally, in February 2023, we are planning to conduct an international workshop that will link the Yaeyama Islands and Indonesian islands and consider the relationship between nature and people in island regions. We held a monthly “IDOBATA workshop”. Daisaku Mukai and Junko Goya developed research into the sustainability of performing arts and communities through fieldwork with local residents and artists (Fig. 10), and presented at the Roundtable for Idea Exchange: New Modes of Knowledge for the Global Environment (December, 2022). Unit leader Takahashi participated in the KLASICA-RIHN-IASS international symposium and presented the potential of community formation and cultural inheritance through narratives based on interviews and fishing gear surveys conducted by the CCU in the Ryukyu Arc.

     

    Governance Unit (GU)

    1-1) In the awareness survey on nature reserves, we analyzed the difference in citizen’s reactions according to the framing of World Natural Heritage. Results showed that, contrary to initial predictions, no significant differences were observed. 1-2) In the awareness survey on the balancing of human movement and infection countermeasures during the COVID-19 crisis, we analyzed whether the negative reaction to human movement could be mitigated by obtaining health certificates and infection control certification by local governments. Results clarified that the negative reactions of local residents to visitors were alleviated by visitors having health certificates (proof of testing negative for COVID-19 and vaccination certificate). It also became clear that the negative reactions of tourists to the destinations that they visited were mitigated by the infection control certification by local governments. However, it also became clear that the effectiveness of health certificates and infection control certifications is conditioned by the public’s trust in science and cultural biases.

    2-1) Regarding the institutional analysis of nature reserves, a preliminary field survey was conducted at Sekisei Lagoon. We noticed that changes in the farming environment due to changes in international circumstances has increased interest in composting livestock waste among residents, and that it may lead to a reduced load from the land area to sea area. 2-2) We revealed the negotiation mechanism concerning regulation such as the acquisition, utilization, and profit sharing of digital sequence information on genetic resources. 2-3) Preliminary survey was conducted in Okinawa and Kagoshima Prefecture to clarify the background and impact of tourism on coral reef islands.

    3In the systematic review of research on adaptive governance and groundwater governance, we continued with our work in identifying the literature to be reviewed and the preparation of a codebook.

     

    Knowledge Bridging Unit (KU)

    We implemented the environmental education event, “Mizunowa Laboratory Yoron” at Yoron Island. The construction of a network with people from various sectors, such as the Yoron Town Board of Education, Fisheries Cooperative, and local marine operators during this process is an important achievement alongside the implementation of the event.

    We utilized the visualization tool for mapping the water cycle in the southern part of Okinawa Island to a topographical model, called “P+MM”, at a meeting with local farmers in Yaese Town. Participants were able to freely manipulate P+MM and we succeeded in achieving a lively discussion on the topic. This initiative contributes to the project’s goal of “integration of scientific knowledge and local knowledge though visualization” by making it possible to interview local residents about social issues based on the results of natural science research.

     

    Results can be evaluated as having overfulfilled

    GU surveys suggest that policy effectiveness can be influenced not only by trust in knowledge, but also by awareness of culture.

    An NU member was selected for NEDO’s R&D consignment project.

     

    Points to be evaluated that the goals were not reached

    A research meeting was held at Halu Oleo University (HOU). However, field surveys by Japanese researchers were not possible due to unstable transportation to Wakatobi, which is research site. With the signing of an MoU with HOU and Wakatobi Regency, the HOU team is conducting a baseline survey. Issues for the HOU survey included a request for cooperation from the Japanese side in understanding groundwater flow rates and basins, as well as understanding the amount of water resources. In the next fiscal year, we would like to dispatch research tools and research staff for conducting a joint survey in order to respond to this request.

     

    Notable achievements and challenges as to contribution to the RIHN programs

    The Taniguchi program advocates the “co-creation of a future society based on the linkage of global human systems”. LINKAGE regards coral reef islands as a system that integrates the land and sea, and aims to clarify the various thresholds and linkages that exist within them and contribute to the construction of a resilient society. This is consistent with the direction of the Taniguchi program. We also plan to actively develop communication tools that encourage changes in values and behavior, and contributions can be made in this regard as well. Additionally, LINKAGE emphasizes measurements, observation, and monitoring of the interaction ring between natural systems and human society, and contributions to the Taniguchi program can be made in this regard as well.

     

    Future tasks

     

    Research plan for next year

    Natural System Unit (NU)

    We will conduct chemical analysis of coral cores that were collected on Yoron Island in a detailed chronological order, and clarify the relationship between it and human activities on the island.

    We will also analyze the annual rings of giant clams, and analyze the changes in the ocean surrounding Yoron Island over a longer span of several thousand years.

    We will construct a land-sea integrated 3D material cycle simulation model with the aim of elucidating the water cycle and sea area flow/material cycle that is specific to Sekisei Lagoon. We will determine the form of groundwater reserves and seabed groundwater seepage by electric prospecting and installation of observation wells. We will conduct analyses of the dynamics of coral growth inhibitors such as phosphorus and heavy metals accumulated in inland water, seawater, and seabed sediment in Sekisei Lagoon; estimate the origin of terrestrial loadings based on stable isotopes of boron, nitrogen, and phosphate; and evaluate the health of coral reef ecosystems using microbiota analysis. We will combine these with the results of the monitoring project by the Ministry of the Environment, reproduce them in a model, and elucidate the material cycle of the entire Sekisei Lagoon.

    Collaborating with the Sekisei Lagoon nature restoration project, we will not only conduct the fixed-point coral coverage survey that is ongoing for many years, but also collect seabed sediment. Additionally, we will attempt to visualize high-resolution terrestrial loads and evaluate impacts on juvenile corals through comprehensive genetic analysis, while simultaneously examining the relationship between large-scale bleaching and its recovery process.

    We will conduct a field survey jointly with HOU on Wangi-Wangi Island in Indonesia.

     

    Community Capability Unit (CCU)

    In the next fiscal year, we will continue to conduct interview surveys and surveys of old photographs concerning the use of nature in the target area and its changes in order to clarify the linkages and diversity between the organisms and culture that are nurtured in the life of the islands, and to elucidate the maintenance mechanism of the capability of resource-limited island communities. Additionally, we will conduct social analysis based on various data such as collected narratives, old photographs, and videos, and we will develop research on social norms and changes in local economies regarding the use of nature. Furthermore, we will build a network and conduct a pre- survey for conducting field surveys in Indonesia and Palau.

     

    Governance Unit (GU)

    We will advance the following three types of research in order to clarify the relationship between local governance and global governance. 1) From the perspective of behavioral science, we will conduct research on nature reserves, biocultural diversity, and human movement. 2) From the perspective of institutional analysis, we will conduct research on nature reserves, biocultural diversity, land-sea linkages, and tourism policy. 3) We will make progress on systematic reviews on adaptive governance and groundwater governance.

     

    Knowledge Bridging Unit (KU)

    We will continue Mizunowa Laboratory Yoron (observation/study group on post-excavation coral 1–2 times/year)

    We will propose a marine education program to the Yoron Town Board of Education.

    We will promote utilization of P+MM as an effective presentation tool at Yaese Koyo High School SSH.

    We will verify the effectiveness of P+MM as a knowledge bridging tool.

    Round-table discussion on survey target islands (exchange of opinions with locals who are aware of issues and picking up potential issues)

    Research meetings on survey target islands (discussion of ways to solve problems specific to region by groups divided by region)

    Plenary meetings attended by all members (approximately twice a year)

    Interdisciplinary research seminar (study group to which researchers involved in (super-) interdisciplinary research are invited; 12 times a year)

     

    Tasks for the next fiscal year onward

    The issue faced by the Knowledge Bridging Unit this fiscal year is the bridging of knowledge within the project. In this fiscal year, there were many cases in which different unit members visited the same local field at the same time for surveys and inspections. Therefore, discussions beyond the unit were actively held, and there was a solid foundation for inter-unit collaboration. Meanwhile, the system in which multiple units work together to address individual issues in each field is not yet solid. In the next fiscal year, there is a need to build a system that can sublimate active discussions between units into the formulation and implementation of concrete measures by strengthening cooperation between research units.
