The Gridded Population of the World, Version 4 (GPWv4): Population Density, Revision 11 consists of estimates of human population density (number of persons per square kilometer) based on counts consistent with national censuses and population registers, for the year 2015. A proportional allocation gridding algorithm, utilizing approximately 13.5 million national and sub-national administrative units, was used to assign population counts to 30 arc-second grid cells.

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)
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).
2008-2012 Action Strategy For Nature Conservation Principles For Nature Conservation Progress Report
REPORT 1: PROGRESS ACHIEVED TOWARDS THE OBJECTIVES OF THE ACTION STRATEGY DURING THE PAST FIVE YEARS
It is a 35 paged Evaluation Report on the 7th Pacific Islands Conference on Nature Conservation and Protected Areas event. This evaluation is the result of a questionnaire (Annex 5) handed out at the end of the conference with a 15.3% return rate (47 conference evaluations). The report's structure will be a planning tool for future conferences to measure and assess what worked and what didn’t work at the 7th Conference
A 34 paged report on the 11th Meeting of the Pacific Islands Roundtable for Nature Conservation held in Suva and hosted by IUCN, Pacific Council of Churches, WWF, SPREP, USP and FSPI. It reports the decisions made by the Roundtable on the following issues:
1. The Roundtable Charter (and 8 organisations signed the charter) (see annex 1)
2. The need for a Roundtable Officer to be based at IUCN in Fiji to support the Chair and support the work of the Roundtable. Roundtable organizations agreed to see whether they had resources to support this.
