Internally Displaced Persons (IDPs): Internally displaced persons are persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalized violence, violations of human rights or natural or human-made disasters, or a coercive environment, and who have not crossed an internationally recognized state border. International Protection: The responsibility of the international community to provide comprehensive protection to those who are entitled to it, triggered when a state is unable or unwilling to ensure the protection of its citizens and individuals under its sovereignty or jurisdiction. International protection encompasses three essential elements: (1) physical safety and security, (2) material assistance (relief and basic needs), and (3) legal protection, including facilitation of durable solutions. This framework of protection applies to both refugees and IDPs. Israeli Colonial-Apartheid Regime: The system of colonization and apartheid through which the Israeli state was created and continues to be maintained by. This system is run by all Israeli policies of colonization, institutionalized discrimination, and population transfer aimed at and/or leading to the perpetuation of Israeli domination and denial of the Palestinian people’s inalienable rights (e.g., the right to self-determination and right to reparations including IDPs and refugees’ right to return to their homes). These policies have been enforced through a wide range of laws, measures, and practices such as the forcible displacement of Palestinians, implantation of Zionist colonizers, the dispossession and land confiscation, the denial of access to land, natural resources and services, the suppression, persecution, fragmentation, segregation and isolation of the Palestinian people, the discriminatory zoning and permit regime, and the denial of residency and reparations. Green Line: The 1949 ceasefire line delineating the boundary between Israel and the oPt (West Bank, including East Jerusalem and Gaza Strip). The Green Line is officially called the 1949 Armistice Line. It emerged after the ceasefire agreements concluded in 1949 between the newly established Israeli state and Arab countries (Jordan, Egypt, Lebanon, and Syria). Although Israel has never specified its borders, this line internationally refers to the de facto borders separating between the Palestinian land conquered by Israel in 1947-1949 (also referred to in this survey as 1948 Palestine) and Palestinian land occupied in 1967. In this survey, it is used to distinguish between 1948 IDPs and 1967 IDPs as well as between IDPs and refugees. Mandate for Palestine: A type of international trusteeship entrusted by the League of Nations to Great Britain in 1922. The purpose of the Mandate System was to facilitate the independence of non-self-governing territories. All other states subject to the colonial Mandate System after World War I have since achieved independence. The Mandate for Palestine, however, facilitated Zionist and Israeli colonization of the country in line with the Balfour Declaration.viii viii For more about the Mandate for Palestine and Balfour declaration, see Mandate for Palestine (signed 12 August 1922) C. 529.
