There has been a lot of discussion about "water wars," a term that sounds great, but to which I do not subscribe: wars start and are fought for many reasons and while water has often been a target, tool, or objective of violence, it is certainly hard to ascribe the primary reason for any war to water alone.
That being said, there are very strong and clear connections between water and conflict.
What has impressed the blogger - Peter Gleick - is the list of water conflicts listed chronologically (Water Conflict Chronology) which I also linked to when taking note of the debate in Nature. Check out the post for his favourite "water wars". He finishes...
We must not be complacent about the political and military risks of water disputes. The past examples from the Chronology can help inform our current diplomacy and strengthen tools for reducing violence over water. [...] as tensions and conflicts over water grow, far more care and attention must be given by the diplomatic and military communities to water.
If you are new to my little blog here and as Mr Gleick not too keen on the concept of water wars I suggest you try clicking my water-tag then scroll down a bit. Enjoy.
