The aim of this article is to explore some aspects of strategic and managerial issues that may pose challenges to the proposed Taiwan Strait Tunnel. These issues include political, financial, organizational, and human factors, and a framework for project risk management. The experience and accomplishment of the Eurotunnel are used as parallels to draw out important lessons on threats and opportunities, and raise relevant questions for any future would-be promoter and project leaders to ponder. The issues raised are preliminary and exploratory in nature and only to serve as a basis for further deliberation and debates. 相似文献

The proposed Taiwan Strait Tunnel will raise numerous challenges for environmental professionals. The environmental issues must be incorporated in the preliminary study, planning, design, and construction of the works and be addressed consistently throughout all phases of the project. In this article, the environmental issues that will be encountered in the construction stage are discussed, including environmental impact assessment, environmental monitoring, and specific environmental issues during construction such as spoil handling, air quality and noise control, drainage, and health and safety. The experience and practice of handling environmental issues during the construction English Channel Tunnel are reviewed throughout the discussion. 相似文献

Public participation is one of the central principles of Integrated Coastal Zone Management (ICZM). However, within current public participation practice in coastal decision making there remain questions regarding whether or not the project leaders or participation processes can be considered legitimate. The paper explores the issue of legitimacy, examining case studies of coastal decision making processes from Belgium and France, focusing on the legal constraints for public participation including degree of formality and government style. It reveals that there are legitimacy issues in public participation related to the legal and institutional framework of the project, as well as to the knowledge base, and characteristics of the stakeholders and their interests. This study concludes that legitimacy issues in an ICZM process cannot be solved entirely through an institutional framework and associated legislation. 相似文献

This study takes cognizance of the fact that the TIOMIN (TIOMIN Resources Inc. of Canada) project has resulted in controversy over its handling of environmental issues and especially the Environmental Impact Assessment (EIA). The authors address many of the protracted issues that have slowed the development of the mining project in Kwale. The main emphasis is on the impacts of the mining and mineral separation processes on the environment, including the governing legislation, the role of consultation and public participation, and socioeconomic issues. In their public documents TIOMIN has specified neither the type of minerals it wants to extract from the area nor their chemical composition. It is well known, however that the titanium minerals and zircon targeted have impurities of iron, thorium and uranium. In the absence of an Environmental Management Plan, the effects of stockpiling radioactive wastes and other impurities that could possibly lead to environmental degradation in both the terrestrial and marine environments have not been publically addressed. The measures proposed to mitigate ecological damage as a result of the establishment of a minerals processing plant in the area seem inadequate. Pollution resulting from accidental spillage or breakage could have significant impact on marine life and residents living near the mining site. Other issues that have not been addressed satisfactorily pertain to the use of surface and underground water. The area already faces a huge water deficit and the calculations presented on aquifer recharge and stream flow rates do not indicate the large quantities of water that would be required in the mineral processing plant. The project, if approved in its present state, risks violation of international conventions. Furthermore, it could cause a conflict between Kenya and Tanzania in the event of an oil spill at the proposed ship loading facility at Shimoni. The proposed mining area includes the district's most fertile land, is home to many fisherfolk and is a major tourist destination. An analysis of the effects of this project on other available opportunities must be thoroughly understood to ascertain the economic and environmental benefits and costs of the mining venture. The proposed compensation rate of $1,000 per acre, for resettlement for example, appears to be grossly inadequate. Compensation should take into account family size and structure family assets and the cost of relocation. 相似文献

Natural fisheries in most parts of the world are under pressure due to heavy fishing activities and pollution threats. The establishment of fish and shrimp hatcheries using native species provides an opportunity for replenishment of fish and shrimp stocks in an environmentally responsible manner. This paper provides guidelines for conducting an EIA of fish and shrimp hatcheries in a semi-enclosed water body, such as the Arabian Gulf and Red Sea. The purpose of the guidelines is to outline issues that may be relevant to the design and construction of hatcheries and to identify important factors for consideration in an EIA study. Effective consultations and technical discussions during the design stage with project proponent and relevant government agencies are recommended. Early evaluation of alternative sites and consideration of environmental factors in ascertaining the suitability of intended project site can help minimize potential impacts. Aspects to be considered in depth include impacts on water quality, sediment and habitat loss. The paper also provides suggested mitigation measures for minimizing potential impacts along with key elements to be considered in the development of an adequate Environmental Management and Monitoring Plan. 相似文献

National Persian Gulf Bridge is a communication route between Bandar Abbas port and Qeshm Island located on the southern border of Iran. This causeway has important role for facilitating the transportation system between Qeshm Island and mainland, i.e., Bandar Abbas. Based on geotechnical and geological site investigation records, the bridge is located on the deposits with high seismic possibility and subsequently significant dynamic loading. Therefore, adequate substructure design of this bridge as an offshore project is realized as a major requirement. The geophysical and geotechnical investigations have been done to obtain the subsoil characteristics of the project site. For this purpose, 18 boreholes have been performed to do in situ tests and extract samples for laboratory testings. Data synthesis indicates that in the zones close to Qeshm Island and in the deeper parts of the sea, the strata is made of clay with loose sands and some depths, with silty sands. Hence, instability issues, including the low bearing capacity and the high differential settlement, are significant aspects in analysis and design of substructure for this project. Also, in this paper, the subsoil conditions have been studied from in situ tests such as standard penetration test (SPT) and cone penetration test (CPT) results in order to achieve an appropriate foundation system. Moreover, the necessity of the ground improvement of the site has been investigated to propose an efficient technique for safe and secure construction. Based on the analysis and methods screened, the vibro-replacement method is considered as a suitable and efficient ground improvement method for this project. 相似文献

Including collaboration with industry members as an integral part of research activities is a relatively new approach to fisheries research. Earlier approaches to involving fishers in research usually involved compulsory accommodations of research, such as through compulsory observer programs, in which fishers were seen as subjects of rather than participants in research. This new approach brings with it significant potential benefits but also some unique issues both for the researchers and the participating industry members.In this paper we describe a research project involving the Queensland Coral Reef Finfish Fishery that originated from industry and community concerns about changes in marketing practices in an established commercial line fishery. A key aspect of this project was industry collaboration in all stages of the research, from formulation of objectives to assistance with interpretation of results. We discuss this research as a case study of some of the issues raised by collaboration between industry and research groups in fisheries research and the potential pitfalls and benefits of such collaborations for all parties.A dedicated liaison and extension strategy was a key element in the project to develop and maintain the relationships between fishers and researchers that were fundamental to the success of the collaboration. A major research benefit of the approach was the provision of information not available from other sources: 300 days of direct and unimpeded observation of commercial fishing by researchers; detailed catch and effort records from a further 126 fishing trips; and 53 interviews completed with fishers. Fishers also provided extensive operational information about the fishery as well as ongoing support for subsequent research projects. The time and resources required to complete the research in this consultative framework were greater than for more traditional, researcher-centric fisheries research, but the benefits gained far outweighed the costs. 相似文献

This article presents an overview of smart structures technologies in connection with long-span cable-supported bridges. Considering the broad scope of the smart structures technologies, two subareas, namely, structural health monitoring and structural control technologies, and their applications in long-span cable supported bridges, are identified as the focus of this review. It is believed that by, adopting the smart structures technologies, reliable operation and hazard management of long-span bridges can be achieved much more efficiently and can be made economically feasible, especially for bridges located at sites with high risks of severe natural hazardous events, such as those facing the bridges of the Taiwan Strait Crossing project. The feasibility of and practical issues in implementing the smart structures technologies in the design and construction of long-span cable-supported bridges are also discussed here. Considering the time span of the construction of the Taiwan Strait Crossing, some of the innovative technologies with a high potential for future long-span bridge applications, while still at the stage of exploratory research at the time of writing, are also examined as it is believed these technologies might have become prevalent by the completion time of the Taiwan Strait Crossing project. 相似文献

This article addresses both environmental and socioeconomic issues concerned with the development or operation of the envisaged titanium mining project in Kwale District of Kenya. TIOMIN Resources Inc., of Canada, through its wholly owned Kenyan subsidiary, Kenya Titanium Minerals Ltd., is proposing to develop a titanium sands mine and mineral processing plants which will produce high grades of heavy minerals including rutile, ilmenite, and zircon. In addition, TIOMIN has proposed to develop a ship loading facility at Shimoni, a significant marine habitat in Kenya. When properly designed and implemented, an Environmental Impact Assessment (EIA) is a powerful tool for ensuring that environmental issues are given due consideration during project design, allowing the benefits of the project to be maximized, while reducing the environmental and social costs of development. In Kenya, the EIA has to be conducted according to the requirements of the Kenya Environmental Management and Co-ordination Act (2000) and in compliance with World Bank standards. An EIA document submitted to the enforcement authority, National Environmental Management Authority (NEMA), enables the issuing of an Environmental Impact Assessment License and a Mining License. A number of exploration studies have been undertaken and several sites have been identified for the extraction of titanium minerals and zircon. Many have expressed concern that environmental matters should be considered before a decision about titanium mining is undertaken. Toxic chemicals used in heavy mineral separation processes and disturbance or redistribution of sediment could spell a disaster for the coastal waters. The Wasini channel is home to world class coral reefs, humpback and spotted dolphins, and marine turtles. Another contentious issue is that of radioactivity associated with the minerals zircon and monazite. The coastal zone is a crucial part of the economy, as it supplies a living for a large number of people along the coast. It is envisaged that involuntary resettlement without adequate compensation and viable alternative sites may result in serious socioeconomic consequences. 相似文献

In the early 1990s, integrated coastal management (ICM) in the Mediterranean basin found general acceptance as an important issue both at national and international levels, and since then it has been, though slowly, steadily developed. Donor organizations such as the European Union and the World Bank, and the UNEP's Mediterranean Action Plan played catalyst roles in this development by initiating and supporting pilot projects. In 1992, the European Union launched the Mediterranean programs in by 1999 which the environment, and especially the coastal environment, was considered as a priority issue. Parallel to this development, several NGO initiatives took place for public awareness on pressing coastal issues and in training and education. The idea of MEDCOAST, which is an NGO network of Euro-Mediterranean academic institutions, was born in 1990 and the new initiative was launched in two directions in 1993. One of these was the organization of the First International Conference on the Mediterranean Coastal Environment (2–5 November 1993, Antalya, Turkey), which placed strong emphasis on the management issues. The second was the development of a project proposal to the Med-Campus program of the European Union. The project, which had the title of Educational Programs in Coastal Zone Management, was selected for funding and became operational in early 1994. The first international training program organized by MEDCOAST was the MEDCOAST Institute 94: Coastal Zone Management in the Mediterranean. This three-week long training effort took place in August–September 1994. Since then, MEDCOAST organized eight training programs in by 1999 five different countries, which were participated by 173 professionals representing 31 countries. Development of an international Masters Degree program in ICM was the second goal of the MEDCOAST's Med-Campus project. Efforts for pursuing this goal are still continuing. This paper elaborates the potential for the NGO's contribution to training and education in the field of integrated coastal management in the Mediterranean and the Black Sea by introducing the MEDCOAST experience. It presents the past and planned MEDCOAST efforts and discusses the strengths and limitations of the role of NGOs at the regional scale. 相似文献

The UNEP/GEF project entitled “Reversing environmental degradation trends in the South China Sea and Gulf of Thailand” implemented by United Nations Environment Programme (UNEP) in partnership with seven riparian states bordering the South China Sea was initiated in 2002 and completed in 2008. The project was complex since it addressed three priority areas of concern identified in the Transboundary Diagnostic Analysis namely the loss and degradation of coastal habitats, over-exploitation of fisheries, and land-based pollution. The fourth component of the project was concerned with regional co-ordination including facilitation of national level execution and securing inter-country agreement on project related matters. A number of lessons learnt from implementing the project include, inter alia: the need for a well designed management framework to ensure smooth co-ordination and information exchanges among and within participating countries; the importance of individuals in terms of the success or failure of Inter-Ministry Committees at the national level; separation of scientific and technical issues from political decision-making; the importance of the demonstration site network in encouraging cooperation at the local level; ownership of the project by participating countries; strong involvement of regional and national experts in implementing project tasks; linkages between habitat and fisheries management for developing a regional fisheries refugia network; sharing data through the development of regional databases; productive services of the project coordinating unit; and development of a framework for long-term cooperation in environment management. 相似文献

The paper presents the results of a major assessment of Code adoption and implementation in nine fishing countries in Asia (China, Thailand, Vietnam), Africa (Senegal, Guinea Bissau and Guinea) and in the Caribbean (Jamaica, Dominican Republic and Trinidad & Tobago), which are part of the international research project ECOST. The main findings are that the Code as an international policy instrument remains relevant and adaptable to the current international fisheries context, and that its guiding principles and provisions have been endorsed and adopted in almost unanimous fashion by the countries covered, and integrated into fisheries policy letters and legal frameworks. However, results also suggest that tackling the truly difficult issues in fisheries, such as combating illegal, unreported and unregulated (IUU) fishing or adjusting fishing overcapacity has been a lot less successful. The design and implementation of necessary measures often remains very weak in domains with important economic and political dimensions. The causes for this are attributed to a mix of administrative inertia, lack of political will and stamina, and short-sighted economic considerations. 相似文献
