Two thirds of the population of the Kingdom of Tonga, live on the small, South Pacific raised
limestone island of Tongatapu. Groundwater is the principle source of reticulated fresh water both in
the capital Nuku’alofa and in rural villages and is sourced from a relatively thin, fresh groundwater lens
overlying seawater. This paper describes a comprehensive, integrated assessment of the vulnerability
of fresh groundwater in Tongatapu. Water resources policy and legislation, and the organisation

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:

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

DEFINITION : Annual per capita generation of municipal solid waste

PURPOSE : Accurate measurement of per capita waste generation for better waste management

DESIRED OUTCOME : Stabilisation and subsequent negative trend in household waste generated

DEFINITION : Quantity of generated hazardous wastes processed/treated (including export)

PURPOSE : Treatment and safe storage of hazardous waste mitigates the risk to humans and nature. Hazardous materials can have direct and indirect, chronic or acute impacts

DESIRED OUTCOME : Full treatment/processing of all hazardous waste generated

DEFINITION : % of households connected to central sewerage system

PURPOSE : Tracks progress in managing sewage in a way that minimises the risk of water contamination. Untreated sewage and leaking septic systems are a major source of ground and surface water contamination

DESIRED OUTCOME : Positive trend in % of households connected to central sewerage system

In this report, a set of recommendations is provided for each indicator to support the next best steps for management action that will advance progress towards the target outcome and support Pacific people and biodiversity.
