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

Time series data and graph of Tonga's deepwater fishery total catch 2006-2016.
Marine pollution in the Pacific. Regional data
Tropical Cyclone Gita hit the main island of Tongatapu and the island of ‘Eua on the night of Monday, 12th February 2018 as a destructive category 4 storm, causing severe damages to these two islands which consists of about 80% of the Total population of Tonga.
This assessment uses the post-disaster data collected by the Statistical Department to describe the characteristics of the affected population, nature and spatial concentration of the damage, and the aid required and received at the time of the interview by the Tongan population.
The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
Resource contains raster files for a Digital Elevation Model (DEM) and derived hillshade for Tonga.

This dataset contains all spatial data that is related to the Tonga volcanic eruption. Maps produced are derived from credible data source such as UNOSTAT and UNITAR.
The WASH Baseline Survey is an initiative of the Water and Sanitation Sector which aims to:
1. Gain a better understanding of the water and sanitation situation nationally; and
2. Collect information about Knowledge, Attitude and Practices of the population regarding water use, sanitation status and hygiene behaviour.
Cyclone Evan hit Samoa in December 2012 and caused immense damage and significant losses. This comprehensive assessment estimates those damages and losses, and identifies the needs of the affected population.
In this report, the value of durable physical assets across all economic and social sectors destroyed by Evan (referred to as damage) is estimated at SAT 235.7 million, equivalent to US$103.3 million.
