The only case of a toxic waste dump is of Israel wanting to move the Bedouin AWAY from it, the exact opposite of what you have been falsely claiming.

Of course no-one can be allowed to build and farm just anywhere without permission, not just Bedouin and not just in Israel.

Israeli government uses different means in order to attract the Bedouin into the planned settlements. It offers land lots at very attractive prices on the one hand,[55] and as an extreme measure - following the court order and all the legal procedure - demolishes houses built illegally on state lands and in rare cases even sprays toxic pesticides onto crops[56] planted in unappropriate places. This is done in order to implement law and order in the Negev, as well as to build new settlements there, both for Jews and for the Bedouin, and improve life conditions of the Bedouin by moving them to townships with a developed infrastructure.
