Cash Based Assistance (CBA) has been used by humanitarian organisations in Somalia to assist people in need since 2003. After several years of poor rainfall, the humanitarian community responded to a famine alert issued in January 2017 with a significant scale-up of funding and programmes. Having originally published a 2017 Humanitarian Response Plan (HRP) in November 2016, by May 2017, the Somalia Humanitarian Country Team (HCT) revised the HRP upwards to target 5.5 million people needing assistance. The United Nations (UN), Red Cross, Red Crescent Movement and numerous international and national NGOs delivered a wide variety of life-saving and livelihood support CBA to vulnerable people across the country.
