Profile 【 display / non-display

  • A professor at Yokohama National University, Hiroyuki Matsuda's research encompasses studies of adaptive management and co-management of marine protected areas, risk analysis and game theory. He is the author of two Japanese textbooks on ecology, one of which focuses on the science and ecosystem management of fisheries. His theoretical work on fisheries management has resulted in new ideas, including the "cyclic advantage model," of sardine-anchovy-chub mackerel, in which Matsuda proposed a hypothesis for small pelagic fish stock fluctuations, and "target switching," a novel multi-species management strategy.

     View Summary

    In the context of the process in which Shiretoko was selected as a World Natural Heritage Site, we discuss the functions of bilateral knowledge translators as buffers to resist external pressure. We explore a process that encourages reconfiguration of the international framework represented by World Natural Heritage Site. In the Shiretoko region, through the interaction between fishers and visiting researchers, knowledge systems that contribute to the international value of World Natural Heritage Sites are reorganized to fit local realities. The mechanisms utilized and the value derived from local fisher practices can spread widely via the language of science.

     View Summary

    <p>At the 2020 annual meeting of The Society of Risk Analysis Japan, we hosted a special session focusing on novel coronavirus disease (COVID-19) as an emerging risk. In the context of the COVID-19 pandemic, the regulatory science perspective is very important as countermeasures have to be decided in a very limited time and without sufficient scientific knowledge. The objective of the session was to discuss the contribution of risk science to countermeasures against COVID-19. The topics were as follows: (1) science and policy under the risk governance; (2) risk assessment at mass gathering events; (3) regulatory science of the infection risk management and the regulatory framework issue; (4) comparison of mortality risk and economic impact.</p>

It is also said that "While World Heritage helps to preserve values, BRs are helping to create them", but these points are common with Geoparks. However, at least in Japan, the presence of BR is weaker. Reasons include a top-down network and lack of a recertification system, insufficient professional supervision, on-site inspections and budget sharing. These challenges may help the future of UNESCO global Geoparks.</p>

  • Conflict over the allocation of Pacific bluefin tuna quota in Japan: How to allocate the quota of fluctuating fishery resources

    Matsuda Hiroyuki, Takemoto Yuta, Tanaka Takahiro, Mori Michihisa

    Japanese Journal of Conservation Ecology ( The Ecological Society of Japan )    2020

    Joint Work

     View Summary

    <p>The abundance of Pacific bluefin tuna Thunnus orientalis has decreased markedly in recent years and is subject to strict international fishing quotas. The quotas for purse seine, coastal, and other fisheries are allocated domestically. The rules for domestic allocation are unclear and in some areas the set net fishery greatly exceeded the limit in the 2017/2018 season. The allocation was decided before the allocation method was agreed upon among stakeholders. In this paper, we discuss the grounds for strict quota limitation and how to determine domestic quotas, their problems, and future prospects. By international agreement, there has been a drastic decrease in comparison with the past stock abundance. Japan agreed to the strict catch limit because they expected more recruits to be born in 2015 and 2016. We propose a population reproductive potential that is defined as the sum of the reproductive values of all individuals as a more reasonable indicator of stock abundance than the spawning stock biomass that is used for international fisheries management. It is rational to prioritise coastal fisheries when the stock is low and to allocate more to offshore fisheries when the stock is high to increase the overall catch. In theory, allowing transfer of the catch quota will decrease the release of high-price tuna, while keeping the total quota.</p>

  • Analyzing Annual Newsletters of Local Association for Protection of Waga River: Water Quality Monitoring for Closed Mines and Long-term Changes in Related Topics in Newsletters


    Journal of Japan Society on Water Environment ( Japan Society on Water Environment )  43 ( 6 )   183 - 188   2020

    Joint Work

     View Summary

    <p>A local association, "Wagagawa no seiryu wo mamoru kai" (The Association for Protection of Clean Water of the Waga River) , was established by diverse stakeholders to protect the "clean" Waga River in 1972. As a major activity, the association has been monitoring the water quality (pH and concentrations of Cu, Zn, Cd, Pb, and As) of discharges from closed mines and downstream river sites, and reporting the results in their annual newsletter. To understand how information should be disclosed, it is worth noting that all the monitoring results, including the exceedance of mine discharge standards of the above-mentioned metals, have been made public and discussed in the newsletters. The analysis of the text of the annual newsletters published in 1972-2019 showed long-term primary changes in topics, that is, from (1) initial concern about general environmental pollution to (2) water quality monitoring and measures for preventing environmental pollution by closed mines to (3) the protection of natural environments including aquatic organisms. Our results would contribute to further analysis and discussion of the activities of this association to consider purpose-driven flexible environmental management in abandoned and closed mines in Japan.</p>

    Joint Work

     View Summary

    <p>The limited water-level method is used for the reservoir of the Miharu Dam, located in upstream of the Abukuma River, which flows into the Pacific Ocean, and drawdown of the water level is routinely practiced just before the flood season (June to October). At this time of the year, the surface water temperature of the reservoir reaches around 15℃ at which spawning of largemouth bass, an invasive species, is thought to begin. Hence, the drawdown period coincides with the spawning period of largemouth bass. Several patterns of drawdown were performed in order to evaluate the effects of the drawdown on the spawning of largemouth bass. In an ordinary drawdown, the water level is lowered at a constant rate till the onset of the flood season. In the Miharu Dam reservoir, drawdown is temporarily paused for 2 to 4 days in the midst of drawdown to promote the spawning of largemouth bass. Then, drawdown is resumed to dry up the spawning beds established at the maintained water level. As a result, a considerable number of exposed spawning beds were detected by setting a few maintained periods during a drawdown, called "Stepped Water-level Drawdown", and exposed spawning beds were observed at depths of 0.5 to 2.0 m from the maintained water level. Fries of largemouth bass were captured and the dates of their spawning were estimated from the relationship between length and daily rings (otoliths). The analysis revealed that spawning during the drawdown period scarcely led to hatching. It was also found that 4-stepped drawdown is more effective for exposing spawning beds than 3-stepped drawdown. Population growth simulated by the Leslie matrix given a scenario of 4-stepped drawdown yielded a stable trend over 50 years. These analyses suggest that 4-stepped drawdown before the flood season could be an effective management method to control the recruitment of largemouth bass.</p>
