to the Council for European Palestinian Relations, the agricultural sector formally employs 13.4% of the population and informally employs 90% of the population. Around 183,000 hectares of land in the Palestinian territories are cultivated, of which around half is used for olive production. Olive products earn more in export income than any other agricultural crop. Over the past 10 years, unemployment rates in Palestine have increased and the agricultural sector became the most impoverished sector in Palestine. Palestinian agriculture suffers from numerous problems, blockades to exportation of produce and importation of necessary inputs, widespread confiscation of land for nature reserves as well as military and settler use, confiscation and destruction of wells, and physical barriers within the West Bank. Because the root of the conflict is with land, the disputes between Israel and Palestine are well-manifested in the agriculture of Palestine. Handicrafts A wide variety of handicrafts, many of which have been produced by Arabs in Palestine for hundreds of years, continue to be produced today. Palestinian handicrafts include embroidery work, pottery-making, soap-making, glass-making, weaving, and olive-wood and Mother of Pearl carvings, among others. Some Palestinian cities in the West Bank, particularly Bethlehem, Hebron and Nablus have gained renown for specializing in the production of a particular handicraft, with the sale and export of such items forming a key part of each city's economy. Stonecutting Stonecutting is a traditional source of income for the Palestinian economy. The annual average output per worker in the stone industry is higher than in any other sector. There are 650 stone production outlets in the West Bank, 138 of them in Beit Fajjar. The quarried material is cut into a rich range of pink, sand, golden, and off-white bricks and tiles known as Jerusalem stone. Transportation Communications The World Bank estimated in 2016 that restrictive measures placed by Israel on telecommunication operators in the West Bank have had a notable negative impact on the development of the Palestinian telecommunications networks, which is sustaining losses in the range of $1 billion. These restrictive measures include the denial to operate in 60% of the West Bank under Israeli military administration (Area C), limitations on the importation of technology for ICT companies, requiring Palestinian operators to access international links via a company with Israeli registration, delaying in the provision of mobile broadband, the failure to set in place an independent regulator for the sector in the territories,
