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 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.
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.

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. Reverse-circulation drilling and geoelectrical probes indicate that there is a discontinuous freshwater layer averaging 5m thick beneath Nauru.
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 Papua New Guinea Resource Information System (PNGRIS) is a micro-computer-based georeferenced
database containing information on natural resources, population distribution, rural land use, small-holder economic activity and land use potential (Bellamy 1986). It is compiled at 1:500 000 scale for approximately 5000 Resource Mapping Units (RMUs) covering the entire land area of Papua New Guinea (PNG).
The Highlands Region of Papua New Guinea (PNG), comprising of the Provinces of Western Highlands, Jiwaka, Southern Highlands, Hela, Eastern Highlands, Enga and Simbu, is a major contributor to the PNG economy through its agricultural production and mineral resources. A well maintained road network is essential to facilitate the movement of goods and people.

A Basic Education For All (EFA) is critical if all citizens are to participate in a modern society. This is a
right for all children, both boys and girls, in Papua New Guinea as stated in the National Constitution. A
basic education is essential for the personal development of all people to provide them with the skills and
knowledge to improve their quality of life.
