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. -
What Evidence Exists on the Impacts of Chemicals Arising from Human Activity on Tropical Reef-Building Corals?

A systematic map protocol Dakis‑Yaoba Ouédraogo1* , Romain Sordello2, Sophie Brugneaux3, Karen Burga4, Christophe Calvayrac5,6, Magalie Castelin7, Isabelle Domart‑Coulon8, Christine Ferrier‑Pagès9, Mireille M. M. Guillaume10,11, Laetitia Hédouin11,12, Pascale Joannot13, Olivier Perceval14 and Yorick Reyjol2 Abstract Background: Tropical coral reefs cover ca. 0.1% of the Earth’s surface but host an outstanding biodiversity and provide important ecosystem services to millions of people living nearby. However, they are currently threatened by both local (e.g. nutrient enrichment and chemical pollution of coastal reefs, arising from poor land management, agriculture and industry) and global stressors (mainly seawater warming and acidifcation, i.e. climate change). Global and local stressors interact together in diferent ways, but the presence of one stressor often reduces the tolerance to additional stress. While global stressors cannot be halted by local actions, local stressors can be reduced through ecosystem management, therefore minimizing the impact of climate change on reefs. To inform decision‑makers, we propose here to systematically map the evidence of impacts of chemicals arising from anthropogenic activities on tropical reef‑building corals, which are the main engineer species of reef ecosystems. We aim to identify the combina‑ tions of chemical and coral responses that have attracted the most attention and for which evidence can be further summarized in a systematic review that will give practical information to decision‑makers. -
1 Ecological Engineering Considerations for Coral
ECOLOGICAL ENGINEERING CONSIDERATIONS FOR CORAL REEFS IN THE DESIGN OF MULTIFUNCTIONAL COASTAL STRUCTURES Michael Foley1, Yuko Stender2, Amarjit Singh1, Paul Jokiel2, and Ku‘ulei Rodgers2 A multifunctional structure is being designed for the Kahului Harbor, Maui, Hawai‘i, to mitigate operational problems caused by wave energy while also providing coral reef habitat. There is limited information on how the design of a coastal structure can be manipulated to enhance the ecology of targeted coral communities. To inform the ecological engineering of an artificial coral reef, the relationship between substrate characteristics and coral colonization was investigated through coral recruitment experiments and study of field conditions. Three concrete compositions that differed by the use of basalt, limestone, or recycled aggregates were tested in field and laboratory experiments to determine the impact of each substrate on the recruitment of juvenile hermatypic corals. The concrete test plates were deployed in three environments for a period of about one year, after which the coral recruits on each plate were identified and counted. No significant difference was found in the average number of coral recruits on the concrete mixed with basalt, limestone and recycled aggregate (60 ± 9, 83 ± 17 and 77 ± 14, respectively). Significant differences in coral recruitment were found due to the laboratory tanks, deep water, and shallow water field tests environments (86 ± 11, 135 ± 15 and 4 ± 1, respectively). These results highlight the importance of environmental site conditions for the development of coral reef habitat. A field study was conducted in the vicinity of purposed artificial reef site to relate the topographic features of the surrounding environment to the levels of live coral coverage. -

Coral Health and Disease in the Pacific: Vision for Action
IV. STATE OF KNOWLEDGE IN THE PACIFIC—WHAT DO WE KNOW AND WHAT HAVE WE LEARNED? OVERVIEW OF ISSUES UNIQUE TO THE PACIFIC: BIOLOGICAL & SOCIAL PERSPECTIVES Michael J. Gawel Guam EPA 120 Bengbing St. Y-Papao Dededo, GU 96929 [email protected] Pacific Islands The term “Pacific Islands” in the context of this paper arbitrarily refers to those tropical islands of the central and western Pacific Ocean which support shallow hermatypic coral reefs, but excluding the Hawaiian Archipelago, which is covered in other papers. The tropical Pacific Island nations and territories all support coral reefs and, no doubt, harbor coral diseases, although these have not been scientifically documented in many of the islands. In fact, as part of the U.S. National Action Plan to Conserve Coral Reefs, surveys in 2002 and 2004 of coral reef academic scientists, resource managers, government agencies and NGOs recorded that in the U.S. Pacific islands they perceived “no threat” from coral disease, although American Samoa registered an increase to perception of “moderate threat” in the 2004 survey (Waddell, 2005). This lack of concern partially reflects a lack of information on the status of diseases in many islands. Wilkinson (2004, p. 405) notes that in American Samoa and Micronesia “Coral bleaching and disease were either rare or undocumented in 1994, but are now clearly evident and considered a serious threat to many reefs in the region.” The Pacific island coral reefs range from veneers on newly emergent volcanic islands, to platform-like fringing reefs, to barrier reefs with lagoons, to atolls, and include non- emergent isolated banks. -

It is isolated by distance, deep Bermuda is a subtropical island group in the western North water and major ocean currents from North America, sitting Atlantic (Fig. 10.1a ). A peripheral annular reef tract surrounds 1,060 km ESE from Cape Hatteras, and 1,330 km NE from the islands forming a mostly submerged 26 by 52 km ellipse the Bahamas. Bermuda is one of nine ecoregions in the at the seaward rim of the eroded platform (the Bermuda Tropical Northwestern Atlantic (TNA) province (Spalding Platform) of an extinct Meso-Cenozoic volcanic peak et al. 2007 ) .

However it is paradoxical to notice that their formation at the cellular level or even at the scale of the organism is still poorly known. Effectively, biomineralisation, the process that is at the basis of their edification, is always the subject of numerous researches. Two combined mechanisms lead to the formation of a biomineral, the synthesis/secretion of macromolecules referred to as ‘organic matrix’, and the transport of ions (calcium, bicarbonates and protons in the case of calcification) to the mineralising site. This review shows a view of the works carried out on biominerali- sation in scleractinian corals, including some aspects on the control of calcification by environmental parameters. It also gives insights into the biological basis of the use of coral skeletons as environmental archives in palaeo-oceanography. -

US Military Facilities and Areas
1 2 Although 59 years have passed since the end of the Second World War, Okinawa, which accounts for only 0.6 percent of Japan's total land area, still hosts vast military bases, which represent approximately 74.7 percent of all facilities exclusively used by U.S. Forces Japan. U.S. military bases account for roughly 10.4 percent of the total land area of Okinawa, and 18.8 percent of the main island of Okinawa where population and industries are concentrated. Number of Facilities 3 Sapporo Japan Sea Sendai Seoul THE REPUBLIC OF KOREA Tokyo Osaka Yellow Sea Pusan Nagoya Fukuoka JAPAN Shanghai Kagoshima East China Sea Ryukyu OKINAWA Fuzhou Islands Naha Taipei Miyako Island Ishigaki Island 500Km TAIWAN 1,000Km Luzon THE REPUBLIC OF THE PHILIPPINES 1,500Km Manila 2,000Km Mindanao Palau Borneo Okinawa, which accounts for approximately 0.6% of the total land area of Japan, is the nation's southwestern-most prefecture. It consists of 160 islands, which are scattered over a wide area of ocean span- ning 1,000km from east to west and 400km from north to south. Approximately 1.35 million people live on fifty of these islands. From the prefectural capital of Naha city, it takes about two hours and 30 minutes to fly to Tokyo (approx. 1,550km), one hour and 30 minutes to Shanghai, China (approx. 820km), and one hour to Taipei, Tai- wan (approx. 630km). As Okinawa is situated in a critical location connecting mainland Japan, the Chinese 4 Continent and the nations of Southeast Asia, we expect that Okinawa will become a center for exchange be- tween Japan and the various nations of East and Southeast Asia.
