Climate change in Germany
The Rhineland is historically a heavily industrial and population-dense area which includes the states of North Rhine-Westphalia, Rhineland Palatinate, and Saarland. This region is rich in iron and coal deposits and supports one of Europe's largest coal industries. In the past, sulfuric acid emissions from Rhineland coal plants contributed to acid rain, damaging forests in other regions like Hesse, Thuringia, and Saxony.
Rijnland
When used in the specific Dutch context, "Rijnland" generally refers to the area around the Oude Rijn, the lower reaches of a minor branch of the Rhine river in the Netherlands. This river is referred to as "Rijn" (Rhine) in the Netherlands for historical reasons. This small, heavily-canalised and remote branch of the Rhine was, in fact, the river that the Romans used to call the Rhine and the northern limit of the Roman Empire in this area. The term "Rijnland" is itself ancient.
