Definitions

  • Biodiversity > Bird species, threatened: Bird species, threatened. Birds are listed for countries included within their breeding or wintering ranges. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known.
  • Biodiversity > Fish species, threatened: Fish species, threatened. Fish species are based on Froese, R. and Pauly, D. (eds). 2008. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known.
  • 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.
  • Biodiversity > Number: GEF benefits index for biodiversity is a composite index of relative biodiversity potential for each country based on the species represented in each country, their threat status, and the diversity of habitat types in each country. The index has been normalized so that values run from 0 (no biodiversity potential) to 100 (maximum biodiversity potential)."
  • Biodiversity > Plant species > Higher, threatened: Plant species (higher), threatened. Higher plants are native vascular plant species. Threatened species are the number of species classified by the IUCN as endangered, vulnerable, rare, indeterminate, out of danger, or insufficiently known.
  • 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.
  • CO2 emissions > Kt > Per capita: 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. Per capita figures expressed per 1,000 population.
  • CO2 emissions > Kt per 1000: 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. Figures expressed per thousand population for the same year.
  • Current issues: This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry:
  • Forest area > Sq. km: Forest area is land under natural or planted stands of trees, whether productive or not.
  • 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.
  • Proportion of land area under protection: Terrestrial areas protected to total surface area, percentage.
  • Sanitation > Population with improved sanitation > Urban and rural: Proportion of the population using improved sanitation facilities, total.
  • Water > Drinking water > Population with improved drinking water sources > Rural: Proportion of the population using improved drinking water sources, rural.
  • Water > Drinking water > Population with improved drinking water sources > Urban and rural: Proportion of the population using improved drinking water sources, total.
