The 2008 James Bond film Quantum of Solace pits 007 against an evil criminal syndicate bent on global domination. Sounds par for the course… but this particular network of baddies isn’t using lasers or missiles to cause havoc.

No, the Quantum organisation has a uniquely dastardly plan: seizing control of Bolivia’s water supply.

While the evil syndicate’s role in the film might not be entirely realistic, this piece of fiction does raise a scenario that is worth considering seriously: what would happen if a country’s water supply was cut off? What would be the global fallout?

Think about it: sure, we need water to survive. But it also fuels a country’s commerce, trade, innovation and economic success. This has been the case for time immemorial, from the Nile in Ancient Egypt to the Amazon in the Brazilian rainforest.

While bodies of water typically help form natural borders of countries, several nations tend to share access to rivers or lakes – the Nile runs through nearly a dozen countries alone, for example. Given how conflict-prone humankind is, it’s surprising there haven't been more dust-ups of a “hydro-political” nature.
