SALEM, West Bank — As Palestinians in the West Bank fast from dawn to dusk in scorching heat during the Muslim holy month of Ramadan, tens of thousands of people have been affected by a drought that has greatly reduced the flow to their taps. Israel admits it’s been forced to cut water supplies to the parched area, saying that nearby Jewish settlements have also been affected. The water shortage has harmed farmers, forced people to bathe less and created a booming business for tanker trucks that deliver water. [...] the Palestinian villages in the West Bank and some isolated Israeli settlements are not connected to the national water grid, relying instead on local underground supplies. “The fact there is excess water in Israel means for very first time, the natural water can be shared at low cost to Israel and high gain to Palestinians and Israelis together,” said Bromberg, the director of EcoPeace Middle East, a group that promotes region-wide environmental cooperation.
