In 1984 the OK Tedi Mining Company Limited began mining copper and gold mineralization from Mt. Fubilan, which is located at the headwaters of the OK Tedi. Subsequent mining in the region followed in 1990. Since this time there has been intense monitoring of the environment undertaken by those in the field in order to better understand the possible impact of mining. This book assembles and summarizes research spanning two decades undertaken by leading experts with firsthand experience. Much of this research is contained in internal company reports, giving the reader rare insight and firsthand knowledge. - Documents physical and biologic change in a large tropical river system brought about largely by mining in an otherwise pristine environment - This book brings together a broad rand of disciplines to provide a comprehensive overview of change in a complex and dynamical tropical river system based largely on previously unpublished company reports - The book provides examples of state-of-the-art strategies and methodologies for monitoring environmental impact in a large river system

The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.

One of the major river systems of our country, the Purari River, finds its outlet to the sea in the Gulf of Papua on the southern coast of Papua New Guinea. All highlands provinces contribute to this mighty river: the Erave of the Southern Highlands Province joins with the Kaugel and Wahgi Rivers (Western High lands), the Tua River (Simbu), and Asaro and Aure Rivers of the Eastern High lands Province to make the Purari the third largest river in P. N. G. Unlike its rivals, the Fly and the Sepik, the distance between its escape from the mountains and its entrance to the sea is short. After winding its way mostly through deep gorges flanked by high mountains, the river leaves the foothills of the southern slopes of the central cordillera barely eighty kilometers from the sea. The energy potential of such a river is enormous. Could the waters be utilised in any way to the advantage of the nation? Twelve years ago the Electricity Com mission of Papua New Guinea proposed an answer to this question: the building of a dam across the river in the Wabo area of the Gulf Province. The generation of vast quantities of hydro-electric power could be fed into a national distribu tion grid and heavy industries could be established in the Gulf Province and other suitable localities to benefit from this power.

Discusses the challenges in establishing policy guidelines for sustainable resource use in Melanesian countries. Presents information about natural resource endowment and usage in Melanesia, Fiji, Vanuatu, the Solomon Islands and PNG, and recommends strategies for sustainable development. Includes references and an index. Thistlethwaite is a consultant in forestry and environmental policy in the Pacific region. Davis teaches in the faculty of resource science and management at the Southern Cross University.

Bringing together a diverse group of contributors, this collection addresses the impact of transnational corporations on human rights. Topics covered include corporate social responsibility; the impact of corporations on internal conflicts, and codes of conduct. Case studies range from the negative effects of the Nigerian oil industry to the positive engagement by a logging company with the Nuu-chah-nulth people in Canada. The book uniquely combines the discussion of conceptual issues with an in-depth examination of specific corporations and industries.

Using the experiences of large water infrastructure projects involving the transfer of water from basins considered to have surplus water to those where the demand for water has exceeded or is expected to exceed supplies, this book examines case studies within diverse geographical, climatic, economic, and policy regimes.

All over the world, the awareness of the increasing pollution of rivers, estuaries and the sea with its associated impact on these ecosystems, its effect on organisms, food-chains, water supply and finally on man himself is growing. Estuaries form a link between the limnetic and marine environments, characterized by a variety of complex processes. Most of these phenomena are not yet sufficiently understood, making efficient water quality management a difficult task. The volume has two main objectives: to present the latest information on current estuarine research and to elaborate fundamentals and criteria for planners and decision-makers in water quality management.
