It is more that places with distinct seasons favour different strategies than places with less distinct (e.g the equator). It is more resource variance than the actual amount of resources, as the human population will expand or contract to fit the niche. But when there are regular shocks to the amount of resources (bad winters) that cause change in population levels different strategies might be more evolutionarily adaptive.
