The undermining of economic life in the so-called Area C (61% of the West Bank) constitutes the most important obstacle to the development of the Palestinian economy. The confiscated Palestinian land contains most of the fertile fields, water and other natural resources. The inability of Palestinians to develop economic activities in this area results in a yearly loss of $ 3,4 billion or 85% of GDP according to the World Bank. Whereas exports accounted for more than half of Palestinian GDP in the eighties, they currently amount to less than 15%. Many Palestinians are therefore forced to look for jobs in the settlements even though those settlements are responsible for the general lack of perspectives.
