the challenge with water deal and programs is what happens when you change the social structure of the region. There are political risks, there are power imbalances and other issues to worry about when you mess with something as core as water.

Remember, there is no substitute for water. I can find substitutes for a lot of other things, but as is credited to Mark Twain... "Whiskey's for drinkin' water's for fighting."
