Niger Environment Stats
Definitions
- Adjusted net national income > Constant 2000 US$: Adjusted net national income (constant 2000 US$). Adjusted net national income is GNI minus consumption of fixed capital and natural resources depletion.
- Biodiversity > Mammal species, threatened: Mammal species, threatened. Mammal species are mammals excluding whales and porpoises. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known.
-
CFC > Consumption:
CFC consumption
Units: Ozone Depletion Potential (ODP) Tons (Metric Tons x ODP)
Units: The indicator was obtained by multiplying the Total CFCs emissions (metric tons per ozone depletion potential) with the Per capita CFCs emissions (obtained by dividing the total CFCs emissions by the population in 1997). In calculating the ESI, the base-10 logarithm of this variable was used. - CO2 Emissions per 1000: CO2: Total Emissions (excluding land-use) Units: thousand metric tonnes of carbon dioxide. Figures expressed per thousand population for the same year.
- CO2 emissions > Kt: Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. They include carbon dioxide produced during consumption of solid, liquid, and gas fuels and gas flaring.
- Current issues: This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry:
-
Ecological footprint:
Ecological footprint per capita
Units: Hectares per Person - Endangered species > Mammal species > Number: Mammal species are mammals excluding whales and porpoises. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known."
- Forest area > Sq. km > Per capita: Forest area is land under natural or planted stands of trees, whether productive or not. Per capita figures expressed per 1,000 population.
-
Marine fish catch:
Total marine fish catch
Units: Metric Tons -
Marine fish catch per 1000:
Total marine fish catch
Units: Metric Tons. Figures expressed per thousand population for the same year. - Proportion of land area under protection: Terrestrial areas protected to total surface area, percentage.
- Waste > Local garbage collected: Municipal waste collected.
-
Water > Severe water stress:
Percent of country's territory under severe water stress
Units: Percent of Land Area
Units: This data is derived from the WaterGap 2.1 gridded hydrological model developed by the Center for Environmental Systems Research, University of Kassel, Germany. The modellers derived, for each country, grid cell by grid cell estimates of whether the water consumption exceeds 40 percent of the water available in that particular grid cell. These were then converted to land area equivalents in order to calculate the percentage of the territory under severe water stress.
