This report from 1992 (one of a series of reports from the Tonga Water Supply Master Plan Study) presents the findings of a recent water resources study of the islands in the Kingdom of Tonga. It summarises previous work, documents recent and current investigations and recommends further investigations to gain a better understanding of the water resources. It also outlines details of a proposed national monitoring and protection programme and makes recommendations about legislation for water resource management and protection.

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?
This dataset contains preliminary impact assessments of the Hunga-Tonga-Hunga-Ha'apai volcanic eruption and induced tsunami in January 2022.
The eruptions sent a plume of ash, gas and steam 20 kilometers (12.4 miles) into the air. Satellite imagery showed a massive ash cloud and shockwaves spreading from the eruption. Ash was falling from the sky in the Tonga capital, Nuku'alofa, Saturday evening and phone connections were down. The eruption was likely the biggest recorded anywhere on the planet in more than 30 years, according to experts.
This publication intends to assist project designers, regulators and decision makers to anticipate and address all relevant public health, socio‐economic and environmental concerns that may arise when under‐ taking a desalination project, for obtaining maximum beneficial use of the desalinated water in terms of quality, safety and environmental protection.
