The number of new arrivals arriving in Yemen from across the Red Sea and Gulf of Aden has been continuously increasing since 2012 and peaked in 2016, despite the conflict that erupted in March 2015. These migratory flows to Yemen are mixed in nature but are comprised mostly of migrants from Ethiopia and Somalia. The majority (55%) of the migrants crossing into Yemen are young males, while an estimated 20-30% are unaccompanied or separated children. 15% of migrants are female.?

Migrants have immense protection needs. Migrants and refugees are at risk of exploitation and abuse; discrimination, detention, kidnapping, torture, rape, and forced recruitment are common. New arrivals and stranded migrants usually require the highest level of support. Needs include emergency medical assistance, food, shelter, WASH support, and information on return options and on the dangers of irregular migration.?

Authorities often detain migrants and refugees, regardless of status. They are held in makeshift detention centres with little to no services, and poor sanitation and health conditions. People are dying of preventable illnesses, being shot, forcibly recruited and suffering other inhumane treatment.?Humanitarian organisations face difficulties accessing the sites.?

Major refugee movements (over 1,000 people per year) are also known to occur from Yemen to Somalia and minor refugee movements (under 1,000 people per year) from Yemen to Djibouti.?

INFORM measures Yemen's risk of humanitarian crisis and disaster to be very high, at 7.8/10.?

Humanitarian Access


Fighting in western coastal areas continues to hamper access, particularly around Al Hudaydah, Hajjah and Taizz. Although districts along the southern coast are located outside of conflict-affected areas, most face administrative obstacles that may significantly impede humanitarian activities.?Tensions have been growing between between the Yemeni government and the Southern Transitional Council (STC), including multiple armed groups supportive of either side. Conflict would restrict access in the south.?In Aden, humanitarian organisations have difficulty accessing migrants rounded up and detained by the Yemeni authorities in detention centres.?Migrants and refugees often face language and cultural barriers to accessing humanitarian services.?
