Farming in the Arctic and the subarctic regions did not develop extensively due to the climate being too cold and too dry.
Explanation:
Some climates are better than others for developing crops. In order to grow good produce, the region needs to have agricultural lands that receive adequate precipitations and a moderate climate. Of course you can find specific crops being produced in not so moderate weather, but the arctic and the subarctic regions have proven to be too cold and too dry for farming to develop extensively. Nevertheless, the planet has been experiencing an increase in its average annual temperature, and sooner than later regions like the arctic will be more adequate for farming than ever before, which is not necessarily a good thing, climate wise.
