Presentation on Pacific Islands Region: Ecosystem Approach Critical for Climate Change Adaptation

A comprehensive series of nuclear tests were carried out by the United States at Enewetak Atoll in the Marshall Islands, especially between 1952 and 1958. A Porites Lutea coral that was growing in the Enewetak lagoon within a few km of all of the high-yield tests contains a continuous record of isotopes, which are of interest (e.g. 14 C, 236 U, 239, 240 Pu) through the testing period. Prior to the present work, 14C measurements at ~2-month resolution had shown pronounced peaks in the D 14C data that coincided with the times at which tests were conducted. Here were port measurements of 236 U and 239, 240 Pu on the same coral using accelerator mass spectrometry, and again nd prominent peaks in the concentrations of these isotopes that closely follow those in 14C. Consistent with the 14C data, the magnitudes of these peaks do not, however, correlate well with the explosive yields of the corresponding tests, indicating that smaller tests probably contributed disproportionately to the debris that fell in the lagoon. Additional information about the different tests can also be obtained from the 236 U/ 239 Pu and 240 Pu/ 239 Pu ratios, which are found to vary dramatically over the testing period. In particular, the rst thermonuclear test, Ivy-Mike, has characteristic 236 U/239 Pu and 240 Pu/ 239 Pu signatures which are diagnostic of the rst arrival of nuclear test material in various archives.

The Keeling Curve is the name given to the chart of rising atmospheric CO2 levels, as measured at the Mauna Loa Observatory in Hawaii. So far, none of the action taken to tackle climate change has slowed the curve's inexorable rise. Co2 has now reached the symbolic threshold of 400 parts per million (ppm)

Ecosystem-based adaptation and climate change vulnerability in Choiseul Province, Solomon Islands - a synthesis report.

This cost-benefi t analysis is part of the UNEP Ecosystem-based Adaptation Flagship Program and UN-HABITAT Cities and Climate Change Initiative and is intended to guide decision makers in their consideration of various options for climate change adaptation. While the scope of the research and analysis is confi ned to Lami Town, Fiji, a town adjacent to the capital Suva, general lessons and considerations may also be informative at the national level. Furthermore, the lessons learned will be useful for future comparison of options for Ecosystem-based Adaptation (EbA) to climate change in the Pacifi c region.

The South Pacific Regional Environment Programme (SPREP) was originally established as a result of a decision taken at the Conference on the Human Environment in the South Pacific held in Rarotonga in 1982. It was established as a separate entity within the South Pacific Commission (SPC - now the Secretariat of the Pacific Community) based in Noumea, New Caledonia; and formed part of the UNEP Regional Seas Programme.

The evolution and expansion of the human species over the past few hundred thousand years, an infinitesimal fraction of planetary time, now sees us as the dominant life form on Earth. We are dominant because of our intelligence and adaptability, and our need to constantly strive for newer and better ways of doing things. But there are now six billion of us, predicted to increase to 8-10 billion by 2050, and our domination of the planet is paralleled by the massive impact that we have had on the Earth's ecosystems. A recent mapping of the human footprint on the planet has concluded that more than 80% of the Earth's land surface is directly influenced by humans. We consume 40% of the Earth's net primary productivity, 35% of oceanic shelf productivity and 60% of freshwater runoff. As a result, remaining natural landscapes are rapidly being modified and the Earth's biological diversity continues to decline at an alarming rate. The Millennium Ecosystem Assessment (MEA) has found that in the last several decades 20% of the world’s coral reefs were lost and 20% degraded, while 35% of mangrove area has been lost. The MEA also concluded that humans have likely increased the species extinction rate by as much as 1,000 times over background rates typical throughout Earth's history.
