Environmental conditions and anthropogenic impacts are key influences on ecological processes and associated ecosystem services. Effective management of Tonga’s marine ecosystems therefore depends on accurate and up-to-date knowledge of environmental and anthropogenic variables. Although many types of environmental and anthropogenic data are now available in global layers, they are often inaccessible to end users, particularly in developing countries with limited accessibility and analytical training.
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 years 2000, 2005, 2010, 2015, and 2020. 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.
The Pacific Network for Environmental Assessment (PNEA) Portal is an initiative of the Secretariat of the Pacific Regional Environment Programme (SPREP) to support government officials from Pacific Island countries and territories who work with environmental impact assessment (EIA), strategic environmental assessment (SEA) as well as Environmental and Social Safeguards (ESS).
The portal complements SPREP’s current capacity building program for EIA and SEA - including the recently launched Regional EIA Guidelines, the Coastal Tourism EIA guidelines, and SEA guidelines.
