China's Claim of Sovereignty Over Spratly and Paracel Islands: A Historical and Legal Perspective Teh-Kuang Chang* I. INTRODUCTION (Dn August 13, 1990, in Singapore, Premier Li Peng of the People's Re- public of China (the PRC) reaffirmed China's sovereignty over Xisha and Nansha Islands.1 On December. 29, 1990, in Taipei, Foreign Minis- ter Frederick Chien stated that the Nansha Islands are territory of the Republic of China.2 Both statements indicated that China's claim to sov- ereignty over the Paracel and Spratly Islands was contrary to the claims of other nations. Since China's claim of Spratly and Paracel Islands is challenged by its neighboring countries, the ownership of the islands in the South China Sea is an unsettled international dispute.3 An understanding of both * Professor of Political Science, Ball State University. -
SEDIMENTARY FRAMEWORK of Lmainland FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA
GREAT BARRIER REEF MARINE PARK AUTHORITY TECHNICAL MEMORANDUM GBRMPA-TM-14 SEDIMENTARY FRAMEWORK OF lMAINLAND FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA D.P. JOHNSON and RM.CARTER Department of Geology James Cook University of North Queensland Townsville, Q 4811, Australia DATE November, 1987 SUMMARY Mainland fringing reefs with a diverse coral fauna have developed in the Cape Tribulation area primarily upon coastal sedi- ment bodies such as beach shoals and creek mouth bars. Growth on steep rocky headlands is minor. The reefs have exten- sive sandy beaches to landward, and an irregular outer margin. Typically there is a raised platform of dead nef along the outer edge of the reef, and dead coral columns lie buried under the reef flat. Live coral growth is restricted to the outer reef slope. Seaward of the reefs is a narrow wedge of muddy, terrigenous sediment, which thins offshore. Beach, reef and inner shelf sediments all contain 50% terrigenous material, indicating the reefs have always grown under conditions of heavy terrigenous influx. The relatively shallow lower limit of coral growth (ca 6m below ADD) is typical of reef growth in turbid waters, where decreased light levels inhibit coral growth. Radiocarbon dating of material from surveyed sites confirms the age of the fossil coral columns as 33304110 ybp, indicating that they grew during the late postglacial sea-level high (ca 5500-6500 ybp). The former thriving reef-flat was killed by a post-5500 ybp sea-level fall of ca 1 m. Although this study has not assessed the community structure of the fringing reefs, nor whether changes are presently occur- ring, it is clear the corals present today on the fore-reef slope have always lived under heavy terrigenous influence, and that the fossil reef-flat can be explained as due to the mid-Holocene fall in sea-level. -

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. -
Marine Protected Areas (Mpas) in Management 1 of Coral Reefs
ISRS BRIEFING PAPER 1 MARINE PROTECTED AREAS (MPAS) IN MANAGEMENT 1 OF CORAL REEFS SYNOPSIS Marine protected areas (MPAs) may stop all extractive uses, protect particular species or locally prohibit specific kinds of fishing. These areas may be established for reasons of conservation, tourism or fisheries management. This briefing paper discusses the potential uses of MPAs, factors that have affected their success and the conditions under which they are likely to be effective. ¾ MPAs are often established as a conservation tool, allowing protection of species sensitive to fishing and thus preserving intact ecosystems, their processes and biodiversity and ultimately their resilience to perturbations. ¾ Increases in charismatic species such as large groupers in MPAs combined with the perception that the reefs there are relatively pristine mean that MPAs can play a significant role in tourism. ¾ By reducing fishing mortality, effective MPAs have positive effects locally on abundances, biomass, sizes and reproductive outputs of many exploitable site- attached reef species. ¾ Because high biomass of focal species is sought but this is quickly depleted and is slow to recover, poaching is a problem in most reef MPAs. ¾ Target-species ‘spillover’ into fishing areas is likely occurring close to the MPA boundaries and benefits will often be related to MPA size. Evidence for MPAs acting as a source of larval export remains weak. ¾ The science of MPAs is at an early stage of its development and MPAs will rarely suffice alone to address the main objectives of fisheries management; concomitant control of effort and other measures are needed to reduce fishery impacts, sustain yields or help stocks to recover. -

No-Take Zone at Hoi Ha Wan
NO-TAKE ZONE AT HOI HA WAN THE ISSUE Hoi Ha Wan Marine Park was one of the first marine parks to be established in Hong Kong in 1996. It is recognized as a marine ecological hotspot due to its rich habitat diversity and presence of threatened species. Hoi Ha Wan has 64 species out of the 84 species of coral that occur in Hong Kong, and over 153 fishes, including the endangered Hong Kong grouper. Despite Hoi Ha Wan being a marine reserve, Hong Kong fishermen are still allowed to fish in the area through a licensing system, as in other marine parks. The government has proposed to ban all fishing activities by fishing vessels in some marine parks, including Hoi Ha Wan, though this will not be fully in place until the end of 2021 due to the long legislation and negotiation process involved. Local fishing by hook and line would still be allowed. No-take (that is, no fishing at all) marine reserves have proven to be a highly effective way to protect and restore coastal marine habitats, including coral reefs, and fish communities around the world. WWF is a strong advocate for developing a network of no-take zones within systems of marine protected areas to ensure healthy and resilient ecosystems, fisheries, and species populations. WHAT WE ARE DOING WWF-Hong Kong plans to engage the government and relevant stakeholders to launch a pilot no-take zone within the bay before the formal fishing ban, and conduct systematic baseline biodiversity surveys within the concerned area with involvement of experts, youth, citizen scientists, AFCD specialists and managers, fishers, and the public.
