A/HRC/41/38/Add.1 E. Recommendations to the international community, donors and United Nations agencies, funds and programmes 77. The Special Rapporteur recommends that United Nations agencies, funds and programmes in the Niger: (a) Ensure that all interventions of United Nations agencies, funds and programmes related to migration issues include a legal protection mandate and a clear protection policy anchored in international human rights law, and adopt a comprehensive human rights framework for their work, with full respect for the human rights of migrants and the “do no harm” principle; (b) Reflect on their contribution in support of mixed migration in the Niger to ensure comprehensive United Nations support, that is, all United Nations actors should have specialized staff, activities and funds devoted to monitoring mixed migration (e.g., through observation points). 78. The Special Rapporteur recommends that IOM increase the access of United Nations humanitarian and human rights actors to IOM transit centres to identify and provide specialized assistance to migrants, including children, victims of human rights violations and others in vulnerable situations. IOM should strengthen cooperation and complementarity with United Nations partners to ensure access to migrants in its centres and external monitoring, for example to address migrants’ complaints, which could be done, for instance, by opening UNHCR and UNICEF offices in IOM centres. 79. The Special Rapporteur recommends that the international community, donors and United Nations agencies, funds and programmes: (a) Increase coordination among United Nations actors and with international and local NGOs to ensure that all migrants, and especially the most vulnerable, including children, are able to exercise their human rights; (b) Strengthen identification, assistance and human rights protection programmes for migrants in vulnerable situations who are outside IOM transit centres; (c) Set up mechanisms for the identification, assistance and appropriate referral of migrants in vulnerable situations, following the conceptualization and guidance provided by the Global Migration Group Principles and Guidelines, Supported by Practical Guidance, on the Human Rights Protection of Migrants in Vulnerable Situations; (d) Collect and analyse data on remigration to assess the effectiveness of migration policies and programmes, including the assisted voluntary return programme; (e) Develop a joint United Nations fundraising strategy for projects related to migration and ensure the added value of each United Nations actor and their mandates is reflected therein and is grounded on a human rights-based approach to migration. 19
