Environmental conditions and anthropogenic impacts are key influences on ecological processes and associated ecosystem services. Effective management of Tonga’s marine ecosystems therefore depends on accurate and up-to-date knowledge of environmental and anthropogenic variables. Although many types of environmental and anthropogenic data are now available in global layers, they are often inaccessible to end users, particularly in developing countries with limited accessibility and analytical training.

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.

The Pacific Network for Environmental Assessment (PNEA) Portal is an initiative of the Secretariat of the Pacific Regional Environment Programme (SPREP) to support government officials from Pacific Island countries and territories who work with environmental impact assessment (EIA), strategic environmental assessment (SEA) as well as Environmental and Social Safeguards (ESS). 

The portal complements SPREP’s current capacity building program for EIA and SEA - including the recently launched Regional EIA Guidelines, the Coastal Tourism EIA guidelines, and SEA guidelines.

Final draft SoE professionally with professional layout for final review.

Tonga’s State of Environment Report 2018 is complete and currently awaiting official approval and launch. The report is based on 7 thematic areas and it was developed to answer 3 key questions related to the environment;

1. What is the current condition of the Tongan environment?
2. What are the risks the Tongan environment faces and what measures have been put forward to minimise them
3. Where is the environment of Tonga headed based on the assessed thematic areas?

Tonga's Environment Data Portal was employed as the tool for SOE data storage and sharing

This dataset gives an overview of the Hunga-Tonga Hunga-Ha'apai volcanic eruption that occurred on 15 Jan, 2022 and led to an induced tsunami event.  From updates, to spatial maps and damage preliminary impact assessments detected from Pleiades images. You can easily access and find them all on this dashboard.

In the 30th SPREP meeting held in September this year, the meeting supported the scaling up of environment data management in the Pacific and directed the Secretariat to initiate a process for developing a full-sized project proposal to support the scaling up environmental data management work in the region.

Later in October,  the Inform Project participating countries collectively agree on the need to scale up and extend the Inform Project services beyond 2022.

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

The Australian Government’s Pacific Adaptation Strategy Assistance Program (PASAP) aims to assist the
development of evidence-based adaptation strategies to inform robust long-term national planning and
decision-making in partner countries. The primary objective of PASAP is: ‘to enhance the capacity of partner
countries to assess key vulnerabilities and risks, formulate adaptation strategies and plans and mainstream
adaptation into decision making’ (PASAP, 2011). A major output of PASAP is: ‘country-led vulnerability

In December 1998, Phase Two of the groundwater pollution study in Tonga was completed. This
Report summarises the activities undertaken to complete the study and presents the outcomes. The
Report relates to the conclusion of field studies commenced in June 1997 that were not completed at
that time due to lack of funds. Field studies, laboratory work and preparation of the results for this
completion of the Phase Two were conducted between August and December 1998
