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).

A presentation by Mr Taaniela Kula - from the "Groundwater Governance: a Global Framework for Action"
This report describes the drilling program undertaken during November and December 1997 in the
Pangai – Hihifo and Koulo areas on the island of Lifuka. The purpose of the program was to:
* install seven water salinity monitoring boreholes;
* provide additional training for the Ministry of Works (MOW) drilling crew in the methods used in
the installation of the monitoring system used in this program; and
* instruct the local Tonga Water Board (TWB) staff in monitoring procedures.
Most of the 3000 inhabitants of Lifuka live in four contiguous
villages and have been supplied with water from a well in the middle
of the island since 1976. On commencement of operation, the water
rapidly became too salty for human consumption. The majority of the
island is low-lying and consists of highly porous, uplifted coral
limestone. Hydrogeological assessment found the fresh-water lens to be
very thin and strongly influenced by tidal mixing, sea level changes and
drought. Comparison with the morphology of Bermuda led a search for
e conuence of climate change and seismic events has created signicant environmental problems in
Lifuka, an island of 2,400 people (2011 Census) in Tonga’s Ha’apai Group. e subregion experienced an
earthquake on 3 May 2006 that measured approximately 7.9 on the Richter scale. It resulted in subsidence
of 23 cm of Lifuka Island, eectively creating instant sea-level rise. Erosion had already been already been a
problem on Lifuka for some decades; in the past 40 years, Lifuka has experienced signicant coastal erosion
