NOx emissions per populated area	0.48 thousand metric tons/squ		[34th of 141]
DEFINITION: NOx emissions per populated land area Units: 1000 Metric Tons/Sq. Km. of Populated Land Area Units: We obtained the total emissions for each country by summarizing emissions data, originally available as a grid map with 1 degree x 1 degree cells. Air pollution is generally greatest in densely populated areas. To take this into account, we used the Gridded Population of the World dataset available from CIESIN and calculated the total land area in each country inhabited with a population density of greater than 5 persons per sq. km. We then used this land area as a denominator for the emissions data.

DEFINITION: 1999 total CO2 emissions from fossil-fuel burning, cement production, and gas flaring. Emissions are expressed in thousand metric tons of carbon (not CO2).

DEFINITION: SO2 emissions per populated land area Units: 1000 Metric Tons/Sq. Km. of Populated Land Area Units: We obtained the total emissions for each country by summarizing emissions data, originally available as a grid map with 1 degree x 1 degree cells.

Water > Availability	21.97 thousand cubic metres		[25th of 141]
DEFINITION: Water availability per capita (1961-1990 (avg.)) Units: Thousands Cubic Meters/Person Units: This variable measures internal renewable water (average annual surface runoff and groundwater recharge generated from endogenous precipitation)
SOURCE: Jacaranda Atlas
Water > Dissolved oxygen concentration	6.07 mls/litre		[115th of 141]
DEFINITION: Dissolved oxygen concentration Units: Milligrams/Liter Units: The country values represent averages of the station-level values for the three year time period 1994-96, exceptwhere data were only available for an earlier time period (1988-1993). The number of stations per country varies depending on country size; number of bodies of water; and level of participation in the GEMS monitoring system. The data from "The Wellbeing of Nations" included a smaller subset of stations representing outfalls of major watersheds. An analysis of a sample of countries with numerous stations found that the data for stations in the subset is broadly comparable to the data for all GEMS stations in those countries.

Water pollution, wood industry > % of total BOD emissions	2.23 %		[46th of 114]
DEFINITION: Industry shares of emissions of organic water pollutants refer to emissions from manufacturing activities as defined by two-digit divisions of the International Standard Industrial Classification (ISIC), revision 2: wood (33). Emissions of organic water pollutants are measured by biochemical oxygen demand, which refers to the amount of oxygen that bacteria in water will consume in breaking down waste. This is a standard water-treatment test for the presence of organic pollutants.		View time series

Wildness	0%		[128th of 141]
DEFINITION: Percent of land area having very low anthropogenic impact Units: Percent of Land Area Units: Global grids for population (GPW), land use (USGS AVHRR based classification from EROS data center), VMAP roads, VMAP railways, VMAP coastlines, VMAP major rivers and the stable lights data were all scored for "wildness". The scores were aggregated and normalized.
