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.
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)
Raster data representing the mean levels of chlorophyll in mg/m3 for the surface water layer. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).
Marine data layers for present conditions were produced with climate data describing monthly averages for the period 2000–2014, obtained from pre-processed global ocean re-analyses combining satellite and in situ observations at regular two- and three-dimensional spatial grids.

The TC Outlook is based on statistical analyses of historical tropical cyclones data that occurred dating back to the 1970’s in similar ENSO-Neutral conditions, the same methodology developed by regional centers, with national Tropical Cyclone Outlooks utilizing national datasets.
For Samoa, (7) analogue (mapped) seasons are identical to the current ENSO conditions. Analogue Seasons (1986/87; 1990/91; 2003/04; 2004/05; 2006/07; 2009/10; 2014/15)

The results of the National Water and Sanitation Baseline Survey (NWBS) indicate that 91.3% of Samoans have access to a piped water supply.
*Data extracted from National Water and Sanitation Baseline Survey 2015 (refer to pdf for more information)*
For survey purposes piped water quality was assessed based on enumerator’s observations of water quality (namely visual appearance, taste and smell) at the time of the interview. No scientific measurements of water quality were undertaken as part of this survey.

Average water consumption for SWA customers is in the range of 140 to 180 litres per person per day (L/c.d) which is comparable to international norm of between 150 and 200L/c.d. The SWA aims to further reduce per capita water through demand management practices to encourage wise water usage to preserve and conserve water resources.

In addition, production losses and higher production costs arising from the disaster across all sectors (referred to as losses) are estimated at SAT 229.4 million, or US$100.6 million. Thus the total effects of the disaster amount to SAT 465 million, or US$203.9 million.
Damages to the sector were mostly to water supply infrastructure and on-site sanitation systems, including septic tanks,
pour flush pit latrines, and dry pit latrines. Total damages are estimated at SAT 8.8 million, while losses were estimated
as SAT 3.8 million more.

The overall damages sustained to cultural heritage were assessed as moderate, although there are several landmarks of Samoa that suffered severe damages. The historic buildings of most concern are the Robert Louis Stevenson Museum (RLSM) and the Old Courthouse. Damages at RLSM are mostly to the botanical garden surrounding the museum. In the Old Courthouse, water leakage from the damaged ceiling continues to affect the floor in the building. The assessment also highlights the damage and loss relating to the integrity and authenticity of the Fagaloa–Uofato protected area.
The environmental assets most affected by Cyclone Evan were the lowland forest areas on the southern coast of Upolu. Damage to these assets are expected to result in substantial production losses to the water, forestry, and tourism sectors in particular, as well as cause harm to biodiversity in these areas.

The agriculture and fisheries sectors sustained significant damage and loss. The worst hit agricultural areas are the southwest, central, and southern parts and the central highlands of Upolu island.

It has been found that 55 percent of disaster effects fall within public sector ownership, while the remaining 45
percent of effects are within private enterprises and individual ownership
