The Pacific Climate Change Science Program (PCCSP) was developed to assist decision makers and planners in 14 Pacific island countries and East Timor to understand better how their climate and oceans have changed and how they may change in the future.
This dataset hosts all resources that were developed through the collaboration between Tonga and PCCSP regarding changes in Tonga's climate
Different reports on freshwater supply, groundwater pertaining to Lifuka of Ha'apai, Tonga.
This report is one in a six series produced for the Tonga Water Safety Plan programme
Various reports relating to water source, groundwater, boreholes etc in Tongatapu.
Report on survey work to provide baseline information on the status of reef
fisheries, and to help fill the massive information gap that hinders the effective management
of reef fisheries. Surveys took place 2001, 2002 and 2008.
Reports analysing Agriculture census data and providing detailed statistical tables that users can easily access.
The Tonga NPOA (sharks) is a policy guideline that ensures conservation and management of oceanic sharks in the Kingdom’s fisheries waters. It also promotes long-term sustainability and optimum use of sharks in Tonga’s Tuna longline fishery in accordance to national development policy frameworks, and special needs and requirements to develop and commercialise its fisheries. In the medium-long term, the Plan serves to minimize any adverse environmental effects of fishing on oceanic shark species.
A high level policy document that provides guidance to the management and development of the deep water fisheries in the periods of 2017 - 2019
Project implementation of Pacific HYCOS activities in Tonga had been delayed since Oct
2008 due to difficulties within MLSNR to obtain operational budget and support for proposed
monitoring activities. It had been proposed that MLSNR undertake the regular joint
monitoring activities proposed for Mataki’eua and develop water resource analysis and
reporting skills as well as make improvements to the existing database including inclusion of
paper records and review identified anomalies as well as backup to Tideda.
This chapter provides a brief description of Tonga, its past and present climate as well as projections for the future. The climate observation network and the availability of atmospheric and oceanic data records are outlined.
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
