The Dassanech district is divided into 40 units called kebele. A kebele is the lowest administrative unit responsible for government functions such as local administration, the collection of tax, provision of extension service and food aid, elections, etc. Except for Omorate (the capital of the district), which hosts migrants and local people, all other kebeles are inhabited by agro-pastoral Dassanech communities.
