The world is facing a biodiversity crisis. Nowhere is that more apparent than on oceanic islands where invasive species are a major threat for island biodiversity. Rats are one of the most detrimental of these and have been the target of numerous eradication programmes; a well-established conservation tool for island systems.
The impacts of house mice (Mus musculus), one of four invasive rodent species in New Zealand, are only clearly revealed on islands and fenced sanctuaries without rats and other invasive predators which suppress mouse populations, influence their behaviour, and confound their impacts. When the sole invasive mammal on islands, mice can reach high densities and influence ecosystems in similar ways to rats.
Following the incursion of rats (Rattus rattus) on Taukihepa (Big South Cape Island; 93.9 km²) off southern New Zealand in 1963, and the subsequent extirpation of several endemic species, the New Zealand Wildlife Service realised that, contrary to general belief at the time, introduced predators do not reach a natural balance with native species and that a safe breeding habitat for an increasing number of at risk species was urgently needed.
Rat eradication is a highly effective tool for conserving biodiversity, but one that requires considerable planning eff ort, a high level of precision during implementation and carries no guarantee of success. Overall, rates of success are generally high but lower for tropical islands where most biodiversity is at risk. We completed a qualitative comparative review on four successful and four unsuccessful tropical rat eradication projects to better understand the factors influencing the success of tropical rat eradications and shed light on how the risk of future failures can be minimised.
The Baja California Pacifc Islands, Mexico, are globally important breeding sites for 22 seabird species and subspecies. In the past, several populations were extirpated or reduced due to invasive mammals, human disturbance, and contaminants. Over the past two decades, we have removed invasive predators and, for the last decade, we have been implementing a Seabird Restoration Programme on eight groups of islands: Coronado, Todos Santos, San Martín, San Jerónimo, San Benito, Natividad, San Roque, and Asunción.
Considerable bene?ts can be achieved for indigenous biodiversity when invasive vertebrates are removed from islands. In New Zealand, two logistically challenging eradications were undertaken, one to remove cats (Felis catus) and the other Paci?c rats (Rattus exulans) from Te Hauturu-o-Toi/Little Barrier Island (Hauturu). Here we document the short- and long-term impacts of these interventions on the biodiversity of Hauturu. We also assess the extent to which predicted outcomes were re?ected in the measured responses for a wide range of species.
Many societies have rules rooted in legal tradition that require the sustainable and efficient use of natural resources. The obligation of stewardship is a feature of
westernised legal systems. In nations following the common law tradition, the doctrine of waste requires owners of land to use it sustainably. Elsewhere, customary law systems
demand strict rules governing the allocation and use of resources. There is, therefore, an existing legal culture into which our generation's obligations towards the world's
resources can be set.
It is now widely acknowledged within the scientific community that the global rate of sea- level rise is quickening - and is likely to continue to do so as a result of anthropogenic
climate change. It is expected, therefore, that any resulting increase in the frequency or intensity of extreme sea-level events will cause serious problems for the inhabitants of low-
lying coastal communities and islands during the 21st century.

Tuvalu, a small island nation in the Pacific, has in recent years lost about one metre of land around the circumference of its largest atoll due to changes in storm conditions and rising sea levels. Tuvalu is one of the worlds lowest lying countries, with its highest point standing a mere four and a half metres above sea level. Half of Tuvalus population of 11,000 people live just three metres above sea level

Samoa, a small islands country in the south pacific comprises of four main inhabitated islands and 6 smaller uninhabitated islands. The islands of Samoa lie between latitudes of 13° 15°S to and longitudes of 168° -173° W. The total land area is estimated to be around 2820 km2 whereby Upolu holds 1115 km2 and Savaii with 1700 km2. The capital Apia is located on the northern part of Upolu and is approximately 130 km from Pago Pago, American Samoa, 3000 km from Auckland, New Zealand, 4500 km from Sydney Australia, and 4300 km from Honolulu, Hawaii.
In 2007, the UNFCCC Secretariat prepared a report on
"Investment and Financial Flows to Address Climate
Change".11 The report covers mitigation and adaptation in
various sectors over the period to 2030. The report defines
an investment as the initial (capital) cost of a new physical
asset with a life of more than one year, such as the capital
cost of a gas-fired generating unit or a water supply
system. A financial flow is an ongoing expenditure related
to climate change mitigation or adaptation that docs not
The main purpose of this paper is to help policy makers,
particularly those in developing countries, think about the national policy instruments needed to contribute to the
fight against climate change, how such needs can be articulated in order to seek internal and external financial resources and how these needs may be reflected in negotiations of a future climate change agreement. This paper is an input to a series of workshops which the United Nations Development Program (UNDP) will organize in developing countries with the aim of improv-
Climate change is one of the greatest threats to our
planet and its people. Reducing emissions of greenhouse
gases (GHG) is called mitigation. Responding to the impacts of climate change is called adaptation. A certain amount of adaptation will be necessary, no matter what we do. But, there will come a point where it will not be possible to adapt our way out of the problem.
As early as 1990 the Intergovernmental Panel on Climate Change (IPCC) noted that the greatest single impact of climate change might be on human migrationwith millions of people displaced by shoreline erosion, coastal flooding and agricultural disruption.3 Since then, successive reports have argued that environmental degradation, and in particular climate change, is poised to become a major driver of population displacementa crisis in the making.

The World's oceans play a crucial role for life on the planet.
Healthy seas and the services they provide are key to the future
development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves
and plains with huge mountains, canyons and trenches which
dwarf similar structures on land. Ocean currents transport water
masses many times larger than all rivers on Earth combined.

The human drama of climate change will largely be played out in Asia, where over 60 per cent of the world's population, around four billion people, live. Over half of those live near the coast, making them directly vulnerable to sea-level rise. Disruption to the region's water cycle caused by climate change also threatens the security and productivity of the food systems upon which they depend. In acknowledgement, both of the key meetings in 2007 and 2008 to secure a global climate agreement will be in Asia.
