    ABSTRACT : Tsunami Evacuation Building is expected as the emergency shelter. Especially after Great East Japan Earthquake, number of the Tsunami Evacuation Building is increasing rapidly in the local governments. However, since most Tsunami Evacuation Buildings are designation of the existing institution, there are concerned about the validity in the present condition. The purpose of this study is to clarify the feature and issues of disaster preventive performance of Numazu City by considering relation between the sufficiency situation of the Tsunami Evacuation Building and the population distribution. As results, since the capacity of institutions which is specified as the Tsunami Evacuation Building is insufficient, it became clear that the area where disaster prevention performance is low has occurred. Moreover, it found out the difference by the capacity, the location feature, etc., and be attributed to the difference in the cover area of each institution by the uses.

    ABSTRACT : An artificial tidal flat in Okinosu, Tokushima City, was created to compensate for the loss of a natural tidal flat; however, the ecological conditions of the benthic assemblage in the artificial habitat differ extensively from those in the natural habitat. In particular, the mud snail Batillaria cumingi, which dominated the lost habitat overwhelmingly, were found to be rare in the created habitat. In a previous study, we found that the amount of available food for B. cumingii (i.e., diatoms) was significantly lower in the artificial habitat; therefore, we enclosed the snails in both habitats and compared their growth rate to test a “food-limiting hypothesis.” However, we found no significant difference in growth rates or the abundance of food items between the two habitats. It is notable that significantly higher mortality and disappearance rates were observed for the snail only in the created habitat during the experiment. However, our additional experiment showed that the empty shells at the surface sank into the sediment significantly in the created habitat. Thus, we regard a “sinking event” as the main reason for the absence of the mud snail in the created shore.

    ABSTRACT : The purpose of this paper is to analyze gavernmentality of environment on the state and local level in Costa Rica. Using a concept “eco-governmentality” that is expanded on Foucault’s concepts of governmentality, we explain the making process of the resource management regime in the state and reveal local community’s reaction against regulation of resource use under the regime. The research site Ostional village is known as marine turtle’s nesting site and have been practiced the collaborative resource management by the local community and conservation area. Through the case of Ostional, we reconsider the arguments of “eco-governmentality” that have been considered what the local people is the object of “governmentality from above”

    ABSTRACT: Nationwide spatial distribution and temporal alteration of storm surge damage of Japan in 2050 and 2100 were estimated by using global mean temperature change and sea level rise in IPCC 5th Assessment Report and by taking into account population change and adaptation to storm surge. The adaptation is to heighten seawall. The results showed that the three major bays, Seto Inland Sea and Ariake/Yatsushiro Sea have relatively high storm surge damage risks. The nationwide storm surge damage risk changes in proportion to national population change. In case of taking the adaptation to storm surge, the storm surge damage risk is obviously reduced in 2000-2050, although the damage risk increases in 2050-2100.

    ABSTRACT: Studies of the application of a variety of land disposal technologies to the storage and disposal of radioactive waste and soil have been carried out. It is feared that disposal of these materials at sea could result in marine diffusion and seismic and tsunami damage, but the advantages of sea disposal are its large capacity and isolation from the public. However, little research on sea disposal of radioactive waste and soil has been done. We studied the practicality of sea disposal technology as a way to dispose of radioactive waste and soil. For the study, we designed controlled substances sea disposal facilities with 2 Mm3 capacity and Level 2 earthquake resistance. We estimated both the cost of constructing the sea disposal facilities and the risk of exposure to radiation from the waste and soil in the facilities. The estimates were compared with the results of case studies of land disposal. The results showed that sea disposal meets necessary standards and ensures performance equivalent or superior to that of land disposal.

    ABSTRACT : The potential sales of fishery products in coastal areas of Ise Bay was evaluated in order to assess current situation and measures of fishery products sales. The potential sales was modeled by considering spatial distribution of population, purchasing power and transportation convenience in Aich and Mie prefectures, for which various statistical database and GIS are utilized. The potential sales of existing supermarket stores is calculated to describe and understand current situation of fishery products sales. The change of potential sales in the future was also estimated considering population decline, change in age structure, and change in consumption of fishery products. Further, the potential sales of direct sales store was also evaluated to discuss its effectiveness.

    ABSTRACT:As an important part of the Safety-net System of Japanese fishing management, Japanese Fishing Vessel Mutual Insurance which enacted from “Act on Compensation of Damages Related to Fishing Vessels” in 1937 that aims to support the stability of fishery management by providing a compensation smoothly for damages or reparation caused by casualty. This paper analyses the function and the role of the Japanese Fishing Vessel Mutual Insurance during the insurance payment of the fishing boats that were damaged in the Great East Japan Earthquake in 2011. Moreover, this paper also discuss about the difficulties that occurred in the reconstruction of the Great East Japan Earthquake. So far, it has been proven that the function of Japanese Fishing Vessel Mutual Insurance gives positive effects. However, there is more possibility to develop the role of such insurance under the circumstance of the existing system, and expand the range of the mutual insurance in the future.
