Natural and industrial disasters
Some places are more prone to disaster than others. But that does it take to turn a cyclone into a disaster in one place and just a climatic event somewhere else? The main reasons are obvious enough. Economically deprive...

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 driv...
