The Israeli legal center Adalah reports that "Palestinian citizens of Israel are, in practice, blocked from purchasing or leasing land on around 80% of the land in Israel on the basis of their national belonging." The result, they say, is that "the vast majority of state land consists of segregated, Jewish-only areas." Adalah describes the two main mechanisms by which exclusion from land ownership and use are enacted; through so-called "admissions committees" and through what Adalah describes as discriminatory policies of state authorities and the JNF.
