11. In line with A/RES/71/1, the purpose of the programme of action is to facilitate the application of a comprehensive response in support of refugees and countries particularly affected by a large refugee movement, or a protracted refugee situation, through effective arrangements for burden- and responsibility-sharing (Part III.A); and areas for timely contributions in support of host countries and, where appropriate, countries of origin (Part III.B). These parts are to be read as interlinked. 

12. While the CRRF relates specifically to large refugee situations, population movements are not necessarily homogenous, and may be of a composite character. Some may be large movements involving both refugees and others on the move; other situations may involve refugees and internally displaced persons; and, in certain situations, external forced displacement may result from sudden-onset natural disasters and environmental degradation. These situations present complex challenges for affected States, which may seek support from the international community to address them. Support for appropriate responses could build on the operational partnerships between relevant actors, including UNHCR and the International Organization for Migration (IOM), engaging their respective mandates, roles and expertise as appropriate to ensure a coordinated approach.

13. The programme of action is underpinned by a strong partnership and participatory approach, involving refugees and host communities, as well as age, gender, and diversity⁹ considerations, including: promoting gender equality and empowering women and girls; ending all forms of sexual and gender-based violence, trafficking in persons, sexual exploitation and abuse, and harmful practices; facilitating the meaningful participation of youth, persons with disabilities and older persons; ensuring the best interests of the child; and combating discrimination.
