Been reading about this for the past year so though I would post this article. I have only posted the 1st. para. as this is a very long article.

"Asia's Coming Water Wars"
hile the world's attention is focused on record high oil prices, water, like oil, is increasingly emerging as a catalyst for international instability and conflict as the recent upsurge in violence in Sri Lanka illustrates. On July 20, the Liberation Tigers of Tamil Eelam (L.T.T.E.) shut down the Maavilaru dam's sluice gate near the town of Kantalai in the northeastern Trincomalee district, which cut off water supplies for 60,000 people in government-controlled areas. This led the Sri Lankan military to commence an aerial bombardment of Tiger positions and a ground offensive to gain control of the reservoir's control point. The Tigers claim that their actions were sparked by the government's failure to build a water tower to supply L.T.T.E.-controlled areas and responded by going on the offensive in Mutur. With more than 500 people killed since fighting erupted over the disputed waterway, the 2002 ceasefire has now collapsed in all but name.
