Development of organic matter, phosphorus and nitrate in EU 15 rivers Development of organic matter, phosphorus and nitrate in EU 15 rivers
The graphic shows the development of organic matter, phosphorus and nitrate in EU 15 rivers. Water resources in Europe have been profoundly influenced over the past century by human activities, including the construction of dams and canals, large irrigation and drainage systems, changes of land cover in most watersheds, high inputs of chemicals from industry and agriculture into surface and groundwater, and depletion of aquifers. Some of the most...

Population density in the Baltic Sea drainage basin Population density in the Baltic Sea drainage basin
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.

Arable land in the Baltic Sea region Arable land in the Baltic Sea region
Ratio of arable land out of total land use in the Baltic Sea drainage basin. Agriculture is one of the main contributors to the nutrient (in this case, primarily nitrogen) influx into the Baltic Sea, and thus a main driver for the eutrophication problems in the sea. The displays the situation at approximately 1990.

Wetlands in the Baltic Sea drainage basin (BALANS) Wetlands in the Baltic Sea drainage basin (BALANS)
Percentage of wetlands out of total land area for the Baltic Sea drainage basin. The ratios have been estimated from various sources, and resembles the situation at approximately 2000, and is calculated from the BALANS data.

Forests Regulate Groundwater Level Forests Regulate Groundwater Level
Forests can regulate groundwater levels and increase drainage of soils where the water table is close to the surface. If there are salts in the upper soil layers, then removal of forests can result in raised groundwater levels and the movement of salts into the rooting zone of plants (FAO 2008c).

Mining effects on rainfall drainage Mining effects on rainfall drainage
The Acid Mine Drainage (AMD) is the number one environmental problem facing the mining industry. AMD occurs when sulphide-bearing minerals in rock are exposed to air and water, changing the sulphide to sulphuric acid. It can devastate aquatic habitats, is difficult to treat with existing technology, and once started, can continue for centuries (Roman mine sites in Great Britain continue to generate acid drainage 2000 years after mining ceased)....
