"Half the Bedouin population lives in cities.* Bedouin settlements are amongst the most deprived in Israel, and are severely lacking in services such as public transport and banks. The rest of the 76,000 continue to live in tens of "unrecognized villages," some of which predate the existence of Israel.[9] These villages do not appear on any Israeli maps, and are denied basic services like water, electricity and schools. It is forbidden by the Israeli authorities for the residents of these villages to build permanent structures, though many do, risking fines and home demolition.[9] Several, including Wadi el Na'am, are located close to the Ramat Hovav toxic waste dump, and residents have suffered from higher than average incidences of respiratory illnesses and cancer.[13] The Israeli government frequently demolishes homes and sprays toxic pesticides onto crops in the unrecognized villages, including one episode where Bedouin homes were demolished to make way for the establishment of a Jewish town.[14] ..."
