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.

The Pacific region has benefited from a number of regional and national programmes to both assess the impacts of climate change on biodiversity and develop programmes to adapt to climate change. Such programmes are critical considering that the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) 1/ states that the Pacific region has already experienced temperature increases of as much as 1°C since 1910.
Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worlds ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable.
Tongas marine ecosystems are worth at least TOP 47 million per year, exceeding the countrys total export value. We are strongly committed to sustaining these values to build an equitable and prosperous blue economy.

The International Organization for Migration (IOM) was engaged by the Government of the Republic of the Marshall Islands (RMI) to lead community engagements on the National Adaptation Plan (NAP) in eight Atolls. The engagement team was comprised of IOM staff and three Non Governmental Organization partners; Jo-Jikum focusing on youth, Women United Together Marshall Islands (WUTMI) focusing on women and inclusion, Marshall Islands Conservation Society (MICS) focusing on livelihoods.
The tropical seas are liberally sprinkled with coral islands.
Many of them are associated with continents and large continental islands, in relatively shallow water, rising from continental shelves. Many, also, are in deep water - atolls, barrier reef islets round high islands, almost atolls', tops of drowned karsts, and a few moderately elevated atolls. These last are among the most fascinating of all, scientifically.

Pesticides as covered in the project include acaricides,
biological pesticides (bacteria, viruses), defoliants,
dessicants, fumigants, fungicides, herbicides, insecticides,
molluscicides, nematicides, rodenticides and synergists.
Pesticides included are those used in plant protection, in
animal health (products for external use only), in human
health programmes and for urban pest control.
There is a high level of uncertainty with the specific estimation of pollutant loads. A large body of work has
been completed that provided qualitative and quantitative data; however, the noting of data gaps and inherent uncertainties of the methods used have qualified much of the quantitative data. Much of the data are based on rapid assessment methods that utilise generic loading rates, assumed waste flow composition, typical production methods, local production rates. Unfortunately, production rate data are inconsistently available and are difficult to verify.
Recognising the problems of information management and the use of data as a resource many countries of the SPC region have expressed the desire for some form of integrated network to handle information and data relating to the resources and
environment of the Region. Accordingly SPREP commissioned this review of the current situaiton with regard to handling, storage and evaluation of such data in the countries of the region.

The New Guinea mainland and surrounding islands possess an extra-ordinarily rich flora and a great diversity of vegetation types that parallel the diverse physiography of the lands and the resulting climates that prevail. A high proportion (some three-quarters) of the land area has a forest cover,
Ice, snow and climate change are closely linked. The Global Outlook for Ice and Snow investigates those linkages. It also presents information on the trends in ice and snow, the outlook for this century and beyond and the consequences to ecosystems and human well-being of these changes. It covers all parts of the cryosphere (the world of ice): snow, land ice, sea ice, river and lake ice, and frozen ground. The Global Outlook for Ice and Snow was written by more than 70 scientists from around the world.

Multilateral Environmental Agreements (MEAs) are a subset of the universe of international agreements. What distinguishes them from other agreements is their focus on environmental issues, their creation of binding international law, and their inclusion of multiple countries. Over the years, many MEAs have been negotiated and agreed at the international and regional levels. Some have a few Parties; some have almost global participation.
