In Guns, Germs, and Steel, Diamond says it is better to live on an east-west axis. Are there any benefits to living on a north-south axis?
the only thing i can think of is more diverse crops in a north to south area and less diverse in a east to west due to climate
As you know, the bad part of living in a place with a long north-south axis is that crops (even if they are diverse) cannot diffuse along that axis. So when a society north or south of you domesticates a crop, you can't necessarily copy them. That makes it harder for you (and those other societies) to develop. In that case, you should try to think of what benefits there might have been to living in an area where crops couldn't diffuse.
I would argue that a major benefit would be that you are less likely to have your society overrun and conquered by other societies. If you live on a long east-west axis, a society to your east could come, conquer you, and take your lands because they would know how to farm in an area like yours. If you live on a north-south axis, other societies would be less able to conquer you because they would have to adapt to a whole new way of life in order to take your lands.
