OTSU, Shiga Pref. -- Among the many issues delegates to the World Water Forum are debating is how to deal with conflicts between tribes and nations over limited water supplies.

On Friday, water conflict between Israel and Palestine, one of of the world's most complex political problems, was the subject of discussions here.

Since September 1995, when the Oslo II accord was signed between Israel and Palestine, the two sides have been increasingly at odds over the subject of water rights. The fundamental issue is sovereignty, according to Anjad Alawie, an official of the Palestine Water Authority.
