The Oslo II Accord divided the Israeli-occupied West Bank into three administrative divisions: the Palestinian enclaves as "Areas A and B" and the remainder, including Israeli settlements, as "Area C".
The Palestinian enclaves were created by a process of subtraction by allocating to Area C everything that the Israeli government considered "important", thereby consigning the vast majority of West Bank Palestinians to the remaining non-contiguous areas.[1][2]
Area C forms a contiguous territory on 61% of the West Bank, and is administered solely by Israel via the Judea and Samaria Area administration. As of 2015, it is home to 150,000 Palestinians[3] in 532 residential areas, and roughly 400,000 Israelis[4] in 135 settlements and more than 100 unrecognized outposts.
In contrast, Areas A and B are subdivided into 165 enclaves of land that have no territorial contiguity.[2] Area A is exclusively administered by the Palestinian National Authority; Area B is administered by both the Palestinian Authority and Israel. Area A comprises approximately 18% of the total territory of the West Bank and Area B about 22% of the territory, together home to some 2.8 million Palestinians.[5]
The process was very easy. In the agreement signed in '93, all those areas that would be part of final status agreement—settlements, Jerusalem, etc.—were known. So I took out those areas, along with those roads and infrastructure that were important to Israel in the interim period. It was a new experience for me. I did not have experience of mapmaking before. I of course used many different civilian and military organizations to gather data on the infrastructure, roads, water pipes, etc. I took out what I thought important for Israel.
