This is the report for the Reefs at Risk Revisited analysis. Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).

The increased demand for high quality products in export markets, coupled with Pacific Island Countries (PICs) national desire to protect the environment, biodiversity and family farming structures, lead to assume that organic agriculture could offer good prospects for PICs development. Besides market opportunities, organic agriculture could increase PICs food self-reliance and thus, contribute to reducing the alarming trend of dependency on food imports, as well as improving nutrition.
Damage assessment as detected from a Pleiades image acquired on 18 January 2022 in Nomuka Island (Mu'omu'a district, Tonga).
260 structures identified, 52 structures were identified as damaged and/or destroyed, 13 as potentially flooded and almost all structures were covered with ash. This is a preliminary analysis and has not yet been validated in the field
Most atoll ecosystems and a wide range of terrestrial and marine organisms, and genetic or cultivars varieties of
traditional food and other multi-purpose plants are declining in abundance and under threat of either “economic extinction” or extirpation and in need of some form of protection. The severity of the situation is greatest on those more urbanized atolls where both the biodiversity and the local knowledge of biodiversity are threatened.

Terrestrial and marine plants and animals that are rare, endangered or in short supply,
and in need of protection in the atolls of the Pacific Islands.
This excel file include four spreadsheets each representing a separate theme (EMG = Environmental Monitoring and Governance, IOE = Island and Ocean Ecosystems, CCR = Climate Change Resilience, WMPC = waste). Within each theme are the core national environment indicators (scrolling from left to right).

Metadata file for the GIS data (raster and shapefiles) for the global threats to coral reefs: acidification, future thermal stress, integrated future threats, and past thermal stress.
Metadata file for the GIS data (raster and shapefiles) for the local threats to coral reefs: coastal development, integrated local, marine pollution, overfishing, and watershed pollution.
Excel file with spreadsheets for each species. Downloaded from TREDS May 2021.
Maps and associated data from the Turtle Research and Monitoring Database System (TREDS). A summary of the database can be found below.
The Turtle Research and Monitoring Database System (TREDS) provides invaluable information for Pacific island countries and territories to manage their turtle resources. TREDS can be used to collate data from strandings, tagging, nesting, emergence and beach surveys as well as other biological data on turtles.

This document is a review of the status, trends and threats to Tonga’s unique biodiversity since the inception of its own NBSAP in 2006. The review also covers the status of the implementation of objectives and action plans, sectors and cross sector collaboration.
