A/HRC/4/38 page 18 The Office for the Coordination of Humanitarian Affairs 65. The Representative benefits from a close cooperation with OCHA, as well as with the Emergency Relief Coordinator (ERC) and his Deputy in New York. This is underscored not only by the fact that OCHA houses a staff member for his mandate, but also by the open-door policy that senior management has had towards him since the inception of his mandate. Regular exchanges of information, as well as support in the preparation of his missions have helped the effectiveness of his missions, as well as mainstreamed his work as a special procedure in the office of the Emergency Relief Coordinator. 66. In addition to this, the Representative maintained close contact with the Special Advisor to the Emergency Relief Coordinator on IDPs and Director of the Internal Displacement Division (IDD), thus allowing for coordination and synergies and avoiding the duplication of efforts. IDD supported the Representative’s initiatives in the IASC, such as the Operational Guidelines on Human Rights and Natural Disasters and the discussion on benchmarks to determine when displacement can be considered as over. The Representative welcomed the establishment of the new Displacement and Protection Support Service (DPSS) but cautioned that it should not lose its focus on internal displacement. He encouraged the Emergency Relief Coordinator to continue in his leadership role to ensure a comprehensive assistance and protection response to the humanitarian needs of IDPs. On the other hand, at the stakeholders’ meeting on the establishment of the DPSS in OCHA, both the Emergency Relief Coordinator and the Director of IDD made calls for the Representative to become a more vocal advocate for IDPs. The United Nations High Commissioner for Refugees 67. UNHCR is, together with OCHA and OHCHR, the most important partner of the Representative in the United Nations system. In July 2006, the Representative and the High Commissioner for Refugees signed a memorandum of understanding to affirm and further strengthen their cooperation and enhance responsiveness to the protection, assistance and reintegration needs of IDPs. During the reporting period, cooperation and coordination of activities have intensified. In particular, the Representative has regularly received country-specific briefings from UNHCR prior to his missions and subsequently shared his insights with UNHCR staff in the field and at headquarters. The support the Representative has received from UNHCR, particularly in preparation of and during country missions, has greatly enhanced the efficacy of his mandate. The Representative is particularly pleased that UNHCR has, in some countries, taken an active role in implementing his mission recommendations. He looks forward to continued close cooperation with UNHCR, including through joint efforts in training and advocacy. 68. The Representative fully supports UNHCR’s expanded role in support of the inter-agency response to internal displacement situations. The Representative feels that it will be crucial for UNHCR to further enhance its role in protecting IDPs in all relevant situations by building on past experiences and good field practices in ongoing programmes and operations. The Inter-Agency Standing Committee 69. As has been mentioned above in the sections regarding benchmarks for durable solutions and the Operational Guidelines on Human Rights and Natural Disasters (paras. 36-43 and 62-64,
