According to the World Bank report, the other four plants perform poorly concerning efficiency and quality. Based on the number of quarries per km2 in Areas A and B, it is calculated that, were Israel to lift restrictions, a further 275 quarries could be opened in Area C. The World Bank estimates that Israel's virtual ban on issuing Palestinians permits for quarries there costs the Palestinian economy at least US$241 million per year. In International law drawing on the Hague Conventions (Article 55), it is established that an occupying power may reap some value from the resources of the country occupied but not deplete its assets, and that the usufruct must benefit the people under occupation. The Oslo Accords agreed to hand over mining rights to the Palestinian Authority. Israel licenses eleven settlement quarries in the West Bank and they sell 94% of their material to Israel, which arguably constitutes "depletion" and pays royalties to its West Bank military government and settlement municipalities. Thus the German cement firm quarrying at Nahal Raba paid out €430,000 ($479,000) in taxes to the Samaria Regional Council in 2014 alone. The Israeli High Court rejected a petition that such quarrying was a violation by stating that after 4 decades Israeli law must adapt to "the realities on the ground". The state did undertake not to open more quarries. As an illustrative example, a Human Rights Watch report contrasts the difference between a Palestinian-owned quarry company in Beit Fajar and that of a European one working on what Israeli considers its state land. The European company obtained a concession and license to harvest stone, whereas Israel refuses permits for most of the roughly 40 Beit Fajar quarries, or nearly any other Palestinian-owned quarry in the West Bank under Israeli administration. Israel had denied Palestinians permits to process minerals in that area of the West Bank. The products of the Israeli cosmetics firm Ahava, established in 1988, were developed in laboratories at the West Bank Dead Sea settlements of Mitzpe Shalem and Kalya. 60% of their production is sold in the EU market. In 2018 The UN, stating that the violations were both "pervasive and devastating" to the local Palestinian population, identified some 206 companies which do business with Israeli settlements in the West Bank. Roughly 73 percent of global bromine production comes from Israeli and Jordanian exploitation of the Dead Sea. The potential incremental value that could accrue to the Palestinian economy from the production and sales of potash, bromine and magnesium has been conservatively estimated at US$918 million per annum, or 9 percent of GDP.
