Using Livestock to Manage Wildlife Habitat

Geography of Somalia
Somalia is a country located in the Horn of Africa. It is bordered by Ethiopia to the west, Djibouti to the northwest, the Gulf of Aden to the north, the Indian Ocean to the east, and Kenya to the southwest. With a land area of 637,657 square kilometers, Somalia's terrain consists mainly of plateaus, plains and highlands. Its coastline is more than 3,300 kilometers in length, the longest of mainland Africa and the Middle East.In the far north, the rugged east-west ranges of the Ogo Mountains lie at varying distances from the Gulf of Aden coast. Hot conditions prevail year-round, along with periodic monsoon winds and irregular rainfall. Geology suggests the presence of valuable mineral deposits.
