Drought in Somalia since early 2015 has resulted in widespread rural-urban displacement as households move in search of services and livelihood opportunities, with an estimated 761,000 people having been displaced since November 2016. The increased displacement presents significant protection challenges, particularly for women and children, as households lose traditional socio-economic safety nets and frequently experience extremely poor living conditions in Internally Displaced Persons (IDP) sites. The Centrality of Protection Strategy endorsed by the Humanitarian Country Team in early 2018 identifies significant information gaps on the specific protection vulnerabilities faced by IDPs, and has outlined the need for strengthened system-wide data collection, analysis and data management across the protection sector. Against this backdrop, REACH conducted this assessment between January-February 2018 to explore the key protection concerns experienced by IDPs living in formal and informal sites in Somalia across Somaliland, Puntland and South Central Somalia.
