Because of its climate and terrain, large parts of Scandinavia pose problems for agriculture. The Scandinavian countries are situated between around 54 and 70 degrees north, thus forming the northernmost part of Western Christendom. In addition to being far north, large parts of Scandinavia are also highland, particularly in Norway, and to some extent also in northern Sweden. However, because of the Gulf Stream, the climate is far warmer than in any other part of the world at this latitude—by as much as 5 to 7 degrees C. Thus, it is possible to grow grain at around 70 degrees north in Norway.
