A/71/279 2030 Agenda for Sustainable Development, and now the World Humanitarian Summit. Identifying, reaching and assisting internally displaced persons and other most-vulnerable populations must be the highest priority for the present and future efforts to prevent and respond to humanitarian crises. This commitment demands that States and the international community pay new attention and take new and innovative action to protect those at risk of or experiencing internal displacement. 41. Internally displaced persons are some of the most vulnerable, having lost their homes, livelihoods, security and social and community networks and support. Many suffer from family separation during flight and trauma and health problems related to displacement and/or conflict or disasters. They may be at ris k when they are present in or close to ongoing conflicts or disasters, or having to fend for themselves with little access to humanitarian or development assistance. The majority are outside of camps and difficult to reach. Innovative and creative approaches are needed to integrate their protection and assistance needs into development processes. 42. It is frequently some of the most marginalized and most vulnerable in societies, including national, ethnic or religious minorities, or indigenous peoples, who are at risk of displacement. Conflict or disaster may create a downwards spiral of vulnerability in which already marginalized populations face displacement which exacerbates their vulnerability and places them into highly perilous situations of insecurity and extreme poverty, usually driving them to informal settlements in urban areas in search of anonymity and livelihoods. Displacement may be combined with discriminatory attitudes or policies, including denial or deprivation of citizenship, and neglect of the primary responsibility for protection as required under international standards. 43. Particular challenges face some people within internally displaced populations, including older persons, persons with disabilities, unaccompanied minors, or members of the lesbian, gay, bisexual or transgender community. Women are made particularly vulnerable by displacement, including to sexual or gender -based violence and other human rights violations, and consequently require specific protection measures. A key protection element is disaggregated data to provide an evidence base to build a profile of internally displaced persons and assess their needs according to their circumstances. Such data is often lacking and this gap reinforces the significance of the work carried out by bodies such as the Joint Internally Displaced Person Profiling Service (JIPS; see www.jips.org/en/home). 44. The plight of those in protracted displacement is relatively neglected. Failure to resolve protracted displacement accounts in large measure for the increasing populations of internally displaced persons at the global level, as new waves of displacement add to protracted layers of displacement. The longer the duration of displacement, the lower the prospect that durable solutions will be achieved. Equally, internally displaced persons outside camps are often assumed to have found their own solutions (see A/HRC/19/54). Most have not and some have chosen to remain invisible owing to protection concerns. Different methodologies are required, such as helplines and outreach programmes to identify and profile them, assess their needs in the overall context of the hosting communities and address such needs using humanitarian and development approaches. Addressing such internally displaced populations is essential to achieving national goals to solve and reduce internal displacement. 12/25 16-13413
