The political crisis in Yemen, following the 2011 revolution and the civil war that started in March 2015, has caused one of the world’s most devastating humanitarian emergencies. Yemen is affected by widespread undernutrition and a protracted cholera outbreak, which erupted in 2016. Yemen Food Security and Agriculture Cluster, the Water and Sanitation Cluster, the Nutrition Cluster and the Health Clusters launched in October 2017 the Yemen Integrated Famine Risk Reduction (IFRR) strategy. The main objective of the Integrated Famine Risk Reduction strategy is to prevent famine and mitigate hunger by increasing access to food and other life-saving supplies and services, increasing purchasing power, while advocating for measures to bring economic stability. Critical to the success of the strategy has been securing and expanding the buy-in of an ever-growing number of key actors at all levels.
