This plan outlines the objectives, current status, the challenges and the proposed solutions for the fisheries sector of Tonga.
Field report of the mission to Tonga, focusing on coral reefs surrounding the islands in the Ha'apai group (Sep 11-21),
Vava'u (Sep 22-28) and Niuaatoputapu (Sep 29-Oct 1).
Herein, is the final field report on a study that KSLOF has undertaken to assess the health and resilience of the coral reefs in the Kingdom of Tonga . The study took place in September-October 2013.

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.
Metdadata file containing the global distribution of hydrothermal vent fields in WGS84 coordinate system.
Metadata for the Global Mangrove Watch dataset.
Document giving detailed metadata for the Global Distribution of Seamounts and Knolls dataset.
This document contains the metadata for the GEBCO Gridded Bathymetric Data 2020 dataset. GEBCO’s gridded bathymetric data set, the GEBCO_2020 grid, is a global terrain model for ocean and land at 15 arc-second intervals. It is accompanied by a Type Identifier (TID) Grid that gives information on the types of source data that the GEBCO_2020 Grid is based.
If the data sets are used in a presentation or publication then we ask that you acknowledge the source.This should be of the form: GEBCO Compilation Group (2020) GEBCO 2020 Grid (doi:10.5285/a29c5465-b138-234d-e053-6c86abc040b9)
