Environmental Impact of Large-Scale Mining in Papua New Guinea: Mining Residue Disposal by the Ok Tedi Copper-Gold Mine
United Nations Environment Programme

The Ok Tedi copper-gold mine, located in the eastern part of the central mountain range of New Guinea, discharges daily approximately 80,000 tons of ore processing residues and a similar volume of waste rock and overburden into the headwaters of the Ok Tedi River. The Mount Fubilan orebody, which is the source of heavy metal-rich sediments de-posited along the Ok Tedi and on the Fly River floodplain, contains a suite of base metals, of which copper is of pri-mary environmental concern. The Ok Tedi flows into the Fly River 200 km downstream of the discharge point, where the mining wastes carried as suspended load are diluted. In the present study, the deposition of mine-derived sediments in the lower part of the Middle Fly River floodplain, and the hydrochemistry and potential mobilization of trace metals, particularly copper, in the alluvial plain was investigated. To this end, a total of 156 sediment cores and sur-face sediment samples and 117 water samples from the upper Ok Tedi and the Middle and Lower Fly River floodplain were taken. The suspended matter content in Middle Fly River water today is about 5-10 times higher than the natural background of about 60 mg/l.

Combating Global Climate Change by Combating Land Degradation: Proceedings of a Workshop held in Nairobi, Kenya
United Nations Environment Programme

An International Workshop was held to consider land degradation in drylands and its management, particularly as it relates to carbon management as a means to combat global warming. Twenty specialists from nine countries met in Nairobi for 5 days in September 1995 to discuss: • Dryland resources - their extent and condition • Management options for drylands • Linking drylands and their management in global climate particularly as related to carbon emissions and storage in drylands; and • the question of whether burners of fossil fuel can be interested in dryland management/anti-desertification measures would be interested in implementing biotic offset programmes.

Accessing the Canopy : Assessment of Biological Diversity and Microclimate of the Tropical Forest Canopy: Phase I
United Nations Environment Programme

UNEP's project Assessment of Biological Diversity and Microclimate of the Tropical Forest Canopy is a new venture to examine forest canopies by means of a tower crane. Accessing the Canopy is the first major report of the project's findings and it goes a long way towards showing us that the protection of the world's biodiversity can only really be accomplished if we continue to explore, assess and preserve it.

Global climate change and coral reef: implications for people and reefs
Clive, R. W., Robert W. B.

The major theme of this report is an assessment of the potential and expected effects of global climate change on coral reef ecosystems and the peoples associated with them. This was the task of the UNEP-IOC-ASPEI-IUCN Global Task Team on the Implications of Climate Change on Coral Reefs, which was formed and supported by a cooperative effort of the participating agencies.
