Vertical farming can be implemented in any country or city. As most vertical farming operations use indoor controlled-environment agriculture, the outdoor conditions such as soil quality, rainfall, seasons, climate, and topography are not barriers to growing crops.
Indoor vertical farming ensures a steady and reliable output of yield. So while indoor vertical farming can be employed anywhere in the world, countries that suffer from particularly extreme weather events or conditions (such as arid/freezing regions) can particularly benefit from the unique advantages of vertical farming.
