Consider it a meeting of minds, water minds. Water consultants, ambassadors who've built water treaties, and government specialists and negotiators from around the Middle East and Europe gathered in Montreux, Switzerland for a two-day workshop on Water Security in the Middle East last week. Green Prophet, the environment news blog I run, was invited to attend. The object was to explore sustainable and cooperative solutions to water security, and to use the problem of water and turn it into an instrument of peace.
