Kagoshima Univ. Res. Center S. Pac. Vol.6, No. 1, 1985 37 Agricultural Environment of the Back Land of Nagura Bay, Okinawa Prefecture* Tadao C. Katayama**, Akio Shinagawa*** and Teruo Higashi*** Abstract The agricultural environment of the back land of Nagura Bay, Ishigaki Island, Okinawa Prefecture, /'. e., upland factors and cropping systems were discussed on the basis of references and observation in the area. There is a rapid consumption and a high turnover rate for organic matter, nutrients, minerals. To improve soil preserva tion, it is recommended utilization of natural topographical features and plants is more suitable than building artificial structures. Plants with a tap root and deep-rooted trees are good examples of natural stabilization structures. In comparison to the agricultural practices dominated by hand labor and small machines, procedures utilizing large machines are disadvantageous, because they increase the amount of times the land remains bare and they reduce the necessary elasticity in farm practices. It is recom mended to increase the agricultural development cautiously to preserve the environ ment and to keep the local population consensus. Introduction Ishigaki Island lies between 124°04'E and 124°20'E longitude and 24°19'N and 24° 36'N latitude (Fig. 1). In general, Ishigaki Island is said to be characteristic of a sub-tropical region. Because of its sub-tropical nature, it has higher temperatures and more abundant solar energy in comparison with Japan proper. -
Effects of Constructing a New Airport on Ishigaki Island
Island Sustainability II 181 Effects of constructing a new airport on Ishigaki Island Y. Maeno1, H. Gotoh1, M. Takezawa1 & T. Satoh2 1Nihon University, Japan 2Nihon Harbor Consultants Ltd., Japan Abstract Okinawa Prefecture marked the 40th anniversary of its reversion to Japanese sovereignty from US control in 2012. Such isolated islands are almost under the environment separated by the mainland and the sea, so that they have the economic differences from the mainland and some policies for being active isolated islands are taken. It is necessary to promote economical measures in order to increase the prosperity of isolated islands through initiatives involving tourism, fisheries, manufacturing, etc. In this study, Ishigaki Island was considered as an example of such an isolated island. Ishigaki Island is located to the west of the main islands of Okinawa and the second-largest island of the Yaeyama Island group. Ishigaki Island falls under the jurisdiction of Okinawa Prefecture, Japan’s southernmost prefecture, which is situated approximately half-way between Kyushu and Taiwan. Both islands belong to the Ryukyu Archipelago, which consists of more than 100 islands extending over an area of 1,000 km from Kyushu (the southwesternmost of Japan’s four main islands) to Taiwan in the south. Located between China and mainland Japan, Ishigaki Island has been culturally influenced by both countries. Much of the island and the surrounding ocean are protected as part of Iriomote-Ishigaki National Park. Ishigaki Airport, built in 1943, is the largest airport in the Yaeyama Island group. The runway and air security facilities were improved in accordance with passenger demand for larger aircraft, and the airport became a tentative jet airport in May 1979. -
Nansei Islands Biological Diversity Evaluation Project Report 1 Chapter 1
Introduction WWF Japan’s involvement with the Nansei Islands can be traced back to a request in 1982 by Prince Phillip, Duke of Edinburgh. The “World Conservation Strategy”, which was drafted at the time through a collaborative effort by the WWF’s network, the International Union for Conservation of Nature (IUCN), and the United Nations Environment Programme (UNEP), posed the notion that the problems affecting environments were problems that had global implications. Furthermore, the findings presented offered information on precious environments extant throughout the globe and where they were distributed, thereby providing an impetus for people to think about issues relevant to humankind’s harmonious existence with the rest of nature. One of the precious natural environments for Japan given in the “World Conservation Strategy” was the Nansei Islands. The Duke of Edinburgh, who was the President of the WWF at the time (now President Emeritus), naturally sought to promote acts of conservation by those who could see them through most effectively, i.e. pertinent conservation parties in the area, a mandate which naturally fell on the shoulders of WWF Japan with regard to nature conservation activities concerning the Nansei Islands. This marked the beginning of the Nansei Islands initiative of WWF Japan, and ever since, WWF Japan has not only consistently performed globally-relevant environmental studies of particular areas within the Nansei Islands during the 1980’s and 1990’s, but has put pressure on the national and local governments to use the findings of those studies in public policy. Unfortunately, like many other places throughout the world, the deterioration of the natural environments in the Nansei Islands has yet to stop. -

In likewise fashion, the process of doing this research has reaffirmed my confidence that no person is an island either. We’re all more like aquapelagic assemblages… in short, this research would not have been possible without institutional, departmental, familial, and personal support. I owe a great debt of gratitude to the following people and institutions for helping this work come to fruition. My research was made possible by a grant from the Japan Foundation, which accommodated changes in my research schedule and provided generous support for myself and my family in the field. I also thank Professor Akamine Masanobu at the University of the Ryukyus who made my institutional connection to Okinawa possible and provided me with valuable guidance, library access, and my first taste of local ritual life. Each member of my committee has given me crucial guidance and support at different phases of my graduate career, and I am grateful for their insights, mentorship, and encouragement. -

Racial Discrimination in Japan
Joint Civil Society Report on Racial Discrimination in Japan to the Committee on the Elimination of Racial Discrimination (CERD) for its Consideration of the Tenth and Eleventh Combined Periodic Report of Japan (CERD/C/JPN/10-11), August 2018 submitted by ERD Net (Japan NGO Network for the Elimination of Racial Discrimination) ERD Net is a network of NGOs working for the elimination of racial discrimination in Japan. Since the launch of networking in 2007, it has continually intervened the review of human rights situations of Japan by the CERD and other UN human rights mechanisms. Contact: International Movement Against All Forms of Discrimination and Racism (IMADR) 1-7-1, Irifune, Chuo-ku, Tokyo, Japan [email protected] Introduction Since the previous examination of the periodic reports of the Government of Japan by the UN Committee on the Elimination of Racial Discrimination (CERD) in 2014, few positive steps have been taken to combat racial discrimination in the country. In 2016, the legislature adopted two new acts including the ‘Act on the Promotion of Efforts to Eliminate Unfair Discriminatory Speech and Behaviour against Persons Originating from Outside Japan (Hate Speech Elimination Act)’ and the `Act on the Promotion of the Elimination of Buraku Discrimination`. While those measures are welcoming, the gap between the national human rights framework and international human rights law, in particular the International Convention on the Elimination of All Forms of Racial Discrimination (ICERD), remains wide. Despite the repeated requests from Japanese civil society including ERD Net and the UN human rights mechanisms, the Government has been unwilling to enact a comprehensive anti-discrimination law which includes discrimination based on race, colour, descent, national or ethnic origin. -
From Singapore, with a Description of a New Cladiella Species
THE RAFFLES BULLETIN OF ZOOLOGY 2010 THE RAFFLES BULLETIN OF ZOOLOGY 2010 58(1): 1–13 Date of Publication: 28 Feb.2010 © National University of Singapore ON SOME OCTOCORALLIA (CNIDARIA: ANTHOZOA: ALCYONACEA) FROM SINGAPORE, WITH A DESCRIPTION OF A NEW CLADIELLA SPECIES Y. Benayahu Department of Zoology, George S. Wise Faculty of Life Sciences, Tel Aviv University, Ramat Aviv, Tel Aviv 69978, Israel Email: [email protected] (Corresponding author) L. M. Chou Department of Biological Sciences, Faculty of Science, National University of Singapore, 14 Science Drive 4, Singapore 117543 Email: [email protected] ABSTRACT. – Octocorallia (Cnidaria: Anthozoa) from Singapore were collected and identifi ed in a survey conducted in 1999. Colonies collected previously, between 1993 and 1997, were also studied. The entire collection of ~170 specimens yielded 25 species of the families Helioporidae, Alcyoniidae, Paraclcyoniidae, Xeniidae and Briareidae. Their distribution is limited to six m depth, due to high sediment levels and limited light penetration. The collection also yielded Cladiella hartogi, a new species (family Alcyonacea), which is described. All the other species are new zoogeographical records for Singapore. A comparison of species composition of octocorals collected in Singapore between 1993 and 1977 and those collected in 1999 revealed that out of the total number of species, 12 were found in both periods, whereas seven species, which had been collected during the earlier years, were no longer recorded in 1999. Notably, however, six species that are rare on Singapore reefs were recorded only in the 1999 survey and not in the earlier ones. It is not yet clear whether these differences in species composition indeed imply changes over time in the octocoral fauna, or may refl ect a sampling bias. -

Model species may differ from population : to population of a single mimetic species, so different predation pressures might have driven micro- ! evolution towards better mimicry among regions. However, there is scant direct evidence of micro- ! evolutionary change over time in mimicry traits. Papilio polytes shows female-limited Batesian mimicry. : On Okinawa, one mimicry model is Pachliopta aristolochiae, which was not present on the island until ! 1993. In P. polytes, the size of the hind-wing white spot, a mimetic trait, is maternally heritable. Among !specimens collected between 1961 and 2016, the average white spot size was unchanged before the : model's arrival but has rapidly increased since then. However, white spot size showed greater variance ! after the model's establishment than before. This suggests that before 1993, white spot size in this : population was not selectively neutral but was an adaptive trait for mimicking an unpalatable native, !Byasa alcinous, which looks like P. -

Stability and change in the colour lexicon of the Japonic languages John L.A. Huisman, Roeland van Hout and Asifa Majid Radboud University | Radboud University | University of York Previous work on colour lexicons focussed on universal patterns in their structure and evolution. We collected new colour naming data in Japanese and three under-described Ryukyuan languages (Amami, Miyako and Yayeama) to investigate semantic variation and change in the colour lexicon of related languages in a modern context. We found several new colours terms (e.g., midori and guriin for ‘green’) in the lexicon of Ryukyuan speak- ers, apparently resulting from contact with Standard Japanese and English. A comparison of our data with historical data suggests that modern Ryukyuan colour systems are closer to modern Japanese than they are to their historic pasts. However, we also found that modern-day Ryukyuan languages are more similar to each other than they are to Japanese. These findings show the scope of semantic changes that can occur through outside influence and highlight the need for fresh empirical data in the study of semantics in related languages. Keywords: colour, semantics, language variation and change, Japonic, Ryukyuan 1. General introduction As the world around us changes, our language changes with it.Technological and societal developments can increase the cultural salience of a concept and with that boost the need to talk about it.For example, as societies gain greater techno- logical control of colour, the need to communicate about colour becomes more important and more terms are added to partition the colour spectrum (Berlin & Kay 1969; Levinson 2000).
