A/HRC/4/105 Page 18 85. Addressing the challenges of an ever-changing environment, UNHCR is reassessing its mission and is engaged in a thorough structural and management reform process in order to become a more flexible, effective and results-oriented organization. The change process launched in March 2006 serves the review of all structures, systems, processes and staffing arrangements. In order to permit prompt and efficient emergency response, the emergency team at UNHCR and its stockpiles are further strengthened, with the aim of establishing by 2007 an emergency response capacity allowing the deployment within 72 hours at any time of humanitarian staff and relief items sufficient for an exodus of up to 500,000 people. V. CONCLUSIONS 86. Mass exodus, whatever form it might take - internal or involving the crossing of borders - is a source of great suffering and of numerous violations of the human rights and dignity of the men, women and children affected. As recalled by the Commission on Human Rights in its resolution 2005/48, the primary responsibility for ensuring the protection of displaced populations present on their territories lies with States. They have the primary role in the initiation, organization, coordination and implementation of humanitarian assistance for people living within their territory. The international community has a responsibility to cooperate with countries affected by mass exoduses of refugees and displaced persons, in particular developing countries. 87. Recent developments have shown growing recognition of the magnitude of exoduses and displacements, as well as the linkages between mass exoduses and human rights. However, major challenges still remain in preventing these situations and responding appropriately to the protection problems they raise. Further cooperation among all actors involved will be required to address these challenges and respond to the protection needs of the numerous victims. -- -- -- -- --
