Population density in the Baltic Sea drainage basin
Hugo Ahlenius, UNEP/GRID-Arendal
The density of people per square kilometers have been calculated from various statistical sources, and displays the situation at approximately 1990. Population, and specifically cities, act as driving forces in regards to eutrophication on the Baltic Sea, primarily through nutrients (nitrogen, phosphorous) released through sewage plants.
