This wasn't quite the distinction I was going for. It is more places where there is a sudden winter require more long term planning in general, you need furs, shelter or tools to make the shelter to survive the cold. These are things you might not see the immediate need for if it is currently warm and green. This planning might need to be done in summer as well. So tropical/equatorial vs highly seasonal might be the distinction I should have made.

The eskimo kind of lifestyle you describe probably has different pressures to farmers that must store food for the winter, but due to its small size may not have contributed much to the human gene pool.
