I would claim water - groundwater - is a local resource, not global, as a certain part of a country is dependent on a particular reservoir. Of course, water can be bottled or put into containers or tanks and this water can then be transported across the world. People are shipping branded water bottles back and forth, and it is often stupid (Can you spell "Evian" backwards?), but not entirely different from all the other material flows in our global economy. Still, in any amounts relevant for agriculture, water is a local or a regional resource.
