Nauru, in the central Pacific Ocean, is a raised atoll capping a volcanic seamount arising from an ocean floor depth of 4300m. The land area is 22km, and the island rises to 70m above sea level. Drilling has proved dolomitised limestone of upper Miocene or younger age to a depth of 55m below sea level. Gravity and magnetic surveys indicate that the limestone probably overlies volcanic bedrock at a depth of about 500m.
Water resources sustainable management is a vital issue for small islands where groundwater is often the only available water resource. Nauru is an isolated and uplifted limestone atoll island located in the Paciﬁc Ocean. Politecnico di Milano performed a feasibility study for the development of sustainable use of groundwater on the island. Thispaperfocusesontheﬁrstphaseof the study that concerns the conceptual site model development, the hydrogeological characterization and the 2D model implementation.
The problem of seawater intrusion in coastal aquifers and oceanic islands is not a new one and a great deal of research has been undertaken since the late 19th century. The first model was developed in 1888 and is known as the Ghyben-Herzberg. It is a simple model based on the hydrostatic balance between fresh and saline water. With the advent of large computing capacity over the past few decades, more sophisticated models have been developed for the simulation of seawater intrusion and upconing of saline water beneath a pumping well.
The report details the planning considerations including the investigation of the water supply and sewerage infrastructure needs of Nauru for the next 20 years. It is noted that Nauru has underinvested in water and sanitation infrastructure for many decades and significant capital investment will be necessary to meet both the current and future needs for the island community for the provision of safe drinking water and adequate sanitation.
This is the 2018 NIEP developed by DCIE with support from SPREP, UNEP, UNDP. The NIEP is a 5 year implementation plan to address environmental issues.

For the Ninth Pacific Islands Conference on Nature Conservation and Protected Areas December 2013, Secretariat of the Pacific Regional Environment Programme (SPREP) commissioned an assessment of the status of biodiversity and conservation in Oceania. This report assesses the overall state of conservation in Nauru using 16 indicators.

The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.

This dataset holds all the reports that assesses the overall state of conservation in;
A list of international and regional multilateral environmental agreements in which each of the Pacific Island country is a party/signatory of. This is useful for SPREP activities and planning
Dataset with direct internet link and resources pertaining to AquaMaps. It is an online tool for generating model based, large scale predictions of natural occurrences of species. For marine species, the model uses estimates of environmental preferences with respect to depth, water temperature, salinity, primary productivity, and association with sea ice or coastal areas.
This publication ‘Strategic Environmental Assessment – Guidelines for Pacific Island Countries and
Territories’ has been prepared to provide guidance on the application of SEA as a tool to support
environmental planning, policy and informed decision making. It provides background on the use and
benefits of SEA as well as providing tips and guiding steps on the process, including case studies, toolkits
and checklists for conducting an SEA in the Appendices.
These guidelines are intended to assist the national and local authorities such as Environment
UNEP Regional Seas Ports and Studies No. 136.
SPREP Reports and Studies No. 49.
Summary table of the status of Pacific Island countries in relation to International and Regional conventions.
