The Gridded Population of the World, Version 4 (GPWv4): Population Density, Revision 11 consists of estimates of human population density (number of persons per square kilometer) based on counts consistent with national censuses and population registers, for the years 2000, 2005, 2010, 2015, and 2020. A proportional allocation gridding algorithm, utilizing approximately 13.5 million national and sub-national administrative units, was used to assign population counts to 30 arc-second grid cells.
Bio-ORACLE is a set of GIS rasters providing geophysical, biotic and environmental data for surface and benthic marine realms. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).
Linking biodiversity occurrence data to the physical and biotic environment provides a framework to formulate hypotheses about the ecological processes governing spatial and temporal patterns in biodiversity, which can be useful for marine ecosystem management and conservation.
GEBCO's aim is to provide the most authoritative publicly-available bathymetry of the world's oceans. It operates under the joint auspices of the International Hydrographic Organization(IHO) and the Intergovernmental Oceanographic Commission (IOC) (of UNESCO).
GEBCO produces and makes available a range of bathymetric data sets and products. This includes a global bathymetric grid; gazetteer of undersea feature names, a Web Map Service and printable maps of ocean bathymetry.
Conservation International, GRID-Arendal and Geoscience Australia recently collaborated to produce a map of the global distribution of seafloor geomorphic features. The global seafloor geomorphic features map represents an important contribution towards the understanding of the distribution of blue habitats. Certain geomorphic feature are known to be good surrogates for biodiversity. For example, seamounts support a different suite of species to abyssal plains.
This dataset shows the global distribution of seamounts and knolls identified using global bathymetric data at 30 arc-sec resolution. A total of 33,452 seamounts and 138,412 knolls were identified, representing the largest global set of identified seamounts and knolls to date. Seamount habitat was found to constitute approximately 4.7% of the ocean floor, whilst knolls covered 16.3%.
The research leading to these results received funding from the European Community’s Seventh Framework Programme, and from the International Union for Conservation of Nature (IUCN).
The Smithsonian Institution's Global Volcanism Program (GVP) is housed in the Department of Mineral Sciences, National Museum of Natural History, in Washington D.C. We are devoted to a better understanding of Earth's active volcanoes and their eruptions during the last 10,000 years.
The Global Mangrove Watch (GMW) is a collaboration between Aberystwyth University (U.K.), solo Earth Observation (soloEO; Japan), Wetlands International the World Conservation Monitoring Centre (UNEP-WCMC) and the Japan Aerospace Exploration Agency (JAXA).
Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).
The InterRidge Vents Database is a global database of submarine hydrothermal vent fields. The InterRidge Vents Database is supported by the InterRidge program for international cooperation in ridge-crest studies (www.interridge.org).

In June/July 2002 an eradication programme to remove Pacific rats from Maninita Island in the Vava'u group of the Kingdom of Tonga was initiated. The techniques used were similar to those
used in successful rat eradications in New Zealand, in that Pestoff 20R pellets and a network of bait stations were used.
Climate change adaptation is vital for Pacific SIDS. Long-term effects, including the increasing frequency and severity of extreme events such as high rainfall, droughts, tropical cyclones, and storm surges are affecting the people in this region. Coupled with non-climate drivers, such as inappropriate land use, overexploitation of resources, increasing urbanization and population increase, development in the region is increasingly undermined.
Work is based around country visits by the network coordinator to support PILN teams to identify and take strategic action to manage their priority invasive species. The network is functioning by sharing awareness of successful activities being earned out by the teams, providing the mechanism for other teams to do the same, and actively encouraging them to do so.
Capacity building is linked to on-going invasive species projects and achieved through workshops and exchanges.

Small island states present a significant challenge in terms of sustainable tourism development. On a small island there are limited resources, economic and social activities tend to be concentrated on the coastal zone, and the interconnectivity between economic, environmental, social, cultural and political spheres is strong and pervasive. Consequently the sustainable development of tourism is more a practical necessity than an optional extra.
This report presents results from the Supplementary Livelihoods Options for Pacific Island Communities (SLOPIC) study, carried out by the Foundation of the Peoples of the South Pacific
International (FSPI) using New Zealand Aid (NZAid) core
funds.
The main aim of this study was to review supplementary livelihood (SL) projects that have taken place across the South Pacific over the past 5 to 10 years, with a view to extracting 'lessons learned' and identifying the determinants of success.
Eighteen Species of beche-de-mer were recored in a survey of eef flats and seagrass areas in Vanuatu.Composition and diversity was variable in different habitats, and denstities were genereally low.It is unlikely that present stocks could support recommended harvesting quotas.

Two species of sea turtles and eight lizards comprise the herpetofauna of Kapingamarangi Atoll; the giant Micronesian gecko (Perochirus scutellatus) is unknown elsewhere. The mourning gecko (Lepidodactylus lugubris), oceanic gecko (Gehyra
oceanica), and azure-tailed copper-striped skink (Emoia impar) are the most common and widespread species, being recorded on 100%, 97%, and 87% of the 31 islands, respectively. The stump-toed gecko (Gehyra mutilata) and the Pacific blue-tailed skink
The NWRP provides a framework for leadership and coordinated action in the supply of safe, adequate and financially, technically and environmentally sustainable water services to rural, outer island and urban communities in Kiribati and for the protection, conservation, sustainable use and efficient management of Kiribati's water resources. It is directed at improving the welfare and livelihood of I-Kiribati and represents the vision of the Government of Kiribati (GoK) for the water sector.

Mangroves are very special and unique trees.Mangroves are among the few trees that can grow in sea water as well as in places where the saltwater mixes with the fresh water from the land.
Mangroves grow in places with muddy soil and a protected shoreline. They live in large groups called "mangrove forests".
The mangrove forest is home to many different types of plants and trees.
