geography Palestinian enclaves The 1993 Oslo Accords declared the final status of the West Bank to be subject to a forthcoming settlement between Israel and the Palestinian leadership. Following these interim accords, Israel withdrew its military rule from some parts of the West Bank, which was divided into three administrative divisions of the Oslo Accords: Area A, 2.7%, full civil control of the Palestinian Authority, comprises Palestinian towns, and some rural areas away from Israeli settlements in the north (between Jenin, Nablus, Tubas, and Tulkarm), the south (around Hebron), and one in the center south of Salfit. Area B, 25.2%, adds other populated rural areas, many closer to the center of the West Bank. Area C contains all the Israeli settlements (excluding settlements in East Jerusalem), roads used to access the settlements, buffer zones (near settlements, roads, strategic areas, and Israel), and almost all of the Jordan Valley and the Judean Desert. Areas A and B are themselves divided among 227 separate areas (199 of which are smaller than ) that are separated from one another by Israeli-controlled Area C. Areas A, B, and C cross the 11 governorates used as administrative divisions by the Palestinian National Authority, Israel, and the IDF and named after major cities. The mainly open areas of Area C, which contains all of the basic resources of arable and building land, water springs, quarries and sites of touristic value needed to develop a viable Palestinian state, were to be handed over to the Palestinians by 1999 under the Oslo Accords as part of a final status agreement. This agreement was never achieved. According to B'tselem, while the vast majority of the Palestinian population lives in areas A and B, the vacant land available for construction in dozens of villages and towns across the West Bank is situated on the margins of the communities and defined as area C. Less than 1% of area C is designated for use by Palestinians, who are also unable to legally build in their own existing villages in area C due to Israeli authorities' restrictions, An assessment by the UN Office for the Coordination of Humanitarian Affairs in 2007 found that approximately 40% of the West Bank was taken up by Israeli infrastructure. The infrastructure, consisting of settlements, the barrier, military bases and closed military areas, Israeli declared nature reserves and the roads that accompany them is off-limits or tightly
