pass system, without Israeli checkpoints, between these parts. Under the Oslo Accords, as a security measure, Israel has insisted on its control over all land, sea and air border crossings into the Palestinian territories, and the right to set import and export controls. This is to enable Israel to control the entry into the territories of materials of military significance and of potentially dangerous persons. The PLO's objective for international recognition of the State of Palestine is considered by Israel as a provocative "unilateral" act that is inconsistent with the Oslo Accords. Water resources In the Middle East, water resources are of great political concern. Since Israel receives much of its water from two large underground aquifers which continue under the Green Line, the use of this water has been contentious in the Israeli–Palestinian conflict. Israel withdraws most water from these areas, but it also supplies the West Bank with approximately 40 million cubic metres annually, contributing to 77% of Palestinians' water supply in the West Bank, which is to be shared for a population of about 2.6 million. While Israel's consumption of this water has decreased since it began its occupation of the West Bank, it still consumes the majority of it: in the 1950s, Israel consumed 95% of the water output of the Western Aquifer, and 82% of that produced by the Northeastern Aquifer. Although this water was drawn entirely on Israel's own side of the pre-1967 border, the sources of the water are nevertheless from the shared groundwater basins located under both West Bank and Israel. In the Oslo II Accord, both sides agreed to maintain "existing quantities of utilization from the resources." In so doing, the Palestinian Authority established the legality of Israeli water production in the West Bank, subject to a Joint Water Committee (JWC). Moreover, Israel obligated itself in this agreement to provide water to supplement Palestinian production, and further agreed to allow additional Palestinian drilling in the Eastern Aquifer, also subject to the Joint Water Committee. The water that Israel receives comes mainly from the Jordan River system, the Sea of Galilee and two underground sources. According to a 2003 BBC article the Palestinians lack access to the Jordan River system. According to a report of 2008 by the Food and Agriculture Organization of the United Nations, water resources were confiscated for the benefit of the Israeli settlements in the Ghor.
