Adiarkay (Addi Arkay) is located on the northern slopes of the Simien Mountains. In 1999, the regional government classified its 47 most drought prone and food insecure woredas (local government areas) due to its inaccessibility and lack of basic infrastrcuture. In 2007, a national census recorded approximately 94,000 inhabitants, although many more are likely living there, across a series of inaccessible villages. Catherine and Yalew have worked closely with the local government, partnering to install around 20 water sources across the region.
