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

This EIA report has thus been prepared by the Ministry of Environment and Communications with technical assistance from the JICA Preparatory Survey. The requirements stipulated in the Environmental Impact Assessment Regulations, 2010, and JICA’s “Guidelines for Environmental and Social Considerations (2010)” were referred in the process.
This report provides design details and costs for the proposed long-term improvements to the water supply
system at Hihifo on the island of Tongatapu, Kingdom of Tonga. This report was part of the demonstration project under the Pacific Adaptation to Climate Change (PACC) programme
The Tonga State of the Environment 2018 report has been developed to answer three key questions related
to the environment of Tonga, and is based on seven thematic areas:
• What is the current condition of the Tongan environment?
• What are the risks the Tongan environment faces and what measures have been put forward to minimise them? This could provide lessons for Tonga.
• Where is the environment of Tonga headed based on the assessed thematic areas?
As part of the development of this report, a survey was conducted of around 88% of the Hihifo residents. The
results highlighted that the future of Hihifo’s water supply requires the integration of rainwater and public water
supply system.

This dataset hosts 31 individual environmental indicator assessments that are in the **State of Environment and Conservation in the Pacific Islands : 2020 Regional report.**
Regional indicators are used to understand the current status of conservation in the region and to establish a process for periodic reviews of the status of biodiversity and implementation of environmental management measures in the Pacific islands region.
Each Pacific regional indicator is assessed with regard to:
Williamson and Sabath (1982) have demonstrated a significant relationship between modern population size and environment by examining atoll area and rainfall in the Marshall Islands. The present work seeks to extend that argument into prehistory by examining the relationship of ancient habitation sites and size of aroid pit agricultural systems to atoll land area and rainfall regime along the 1,500-3,500 mm precipitation gradient in the Marshall Islands.
DEFINITION : Trend in consumption of ozone depleting substances (ODS)
PURPOSE : Tracks countries progress to phasing out ODS. Ozone depleting substances destroy the earth’s ozone which protects the earth from UV radiation
DESIRED OUTCOME : Negative trend in ODS consumption
DEFINITION : Trend in percentage production of energy from renewable sources
PURPOSE : Energy generation is a major source of GHG emissions. Pacific island countries also have limited capacity for oil and gas storage and are therefore highly vulnerable to fluctuations in fossil fuel price and availability
DESIRED OUTCOME : Positive trend in energy production from renewable sources
