20.7 million people are in need of humanitarian aid, including 9.8 million people in acute need. Fighting escalated in March 2015, and an armed advance on the capital in September 2014 by Houthis from the north triggered a civil war throughout the country.?? A coalition of Arab states led by Saudi Arabia is supporting the Yemeni government with airstrikes. Activities by southern secessionists, Al Qaeda in the Arabian Peninsula (AQAP) and Islamic State (IS) compound the security and political challenges.? The economy is also failing, with the Central Bank near collapse. ?

The Inter-Agency Standing Committee (IASC) declared Yemen a Level 3 emergency in July 2015. INFORM measures Yemen's risk of humanitarian crisis and disaster at a very high level of 7.6/10. Hazard and exposure as well as lack of coping capacity and vulnerability are all at alarming levels: 8.1/10, 7.9/10 and 6.9/10 respectively.? 

Latest Developments

18/09: Between 27 April and 13 September, 663,400 cholera cases were reported including 2,074 deaths (CFR: 0.31%). The new number of cases per week at the country level has stabilised since the last week of August, however in Sana’a , Shabwah, and Moklalla the number of new cases per week is still increasing.??

Key priorities

WASH: 15.7 million people are in need of WASH assistance.?

Health: 14.8 million people lack access to healthcare. Almost 2,000 health facilities have stopped or reduced operations.??

Food security: Imports of staple foods have decreased significantly since the escalation of conflict, leading to steep price increases. Yemen ordinarily imports 90% of its staple foods.?

Information Gaps and needs

  • Limited information available on the needs of the Muhamasheen minority (10% of population), who live in dire conditions and are more in need than the average population.

  • Underreporting of casualties due to the collapse of the health system. No updates on prevalent diseases such as dengue

  • Limited access means detailed data on humanitarian needs is not always available.
