Crimea or the Autonomous Republic of Crimea is the only autonomous republic of Ukraine. It is located on the northern coast of the Black Sea and on the western coast of the Sea of Azov, bordering Kherson region from the North and occupies a peninsula of the same name.
Crimea is connected to the mainland by the 5–7 kilometers wide Isthmus of Perekop. At the eastern tip is the Kerch Peninsula, which is directly opposite the Taman Peninsula on the Russian mainland. Between the Kerch and Taman peninsulas, lies the 3–13 kilometers wide Strait of Kerch, which connects the waters of the Black Sea with the Sea of Azov.
The Crimean coastline is broken by several bays and harbors. These harbors lie west of the Isthmus of Perekop by the Bay of Karkinit; on the southwest by the open Bay of Kalamita, with the ports of Eupatoria and Sevastopol; on the north by the Bay of Arabat of the Isthmus of Yenikale or Kerch; and on the south by the Bay of Caffa or Feodosiya, with the port of Feodosiya.
The southeast coast is flanked at a distance of 8–12 kilometers from the sea by a parallel range of mountains, the Crimean Mountains. These mountains are backed by secondary parallel ranges. Seventy-five percent of the remaining area of Crimea consists of semiarid prairie lands, a southward continuation of the Pontic steppes, which slope gently to the northwest from the foot of the Crimean Mountains.
The main branches of the Crimean economy are tourism and agriculture. Industrial plants are situated for the most part in the northern regions of the republic. Important industrial cities include Dzhankoy, housing a major railway connection, Krasnoperekopsk and Armyansk, among others. The most important industries in Crimea include food production, chemical fields, mechanical engineering and metal working, and fuel production industries.
