Fertile Crescent

The Fertile Crescent includes a roughly crescent-shaped area of relatively fertile land which probably had a more moderate, agriculturally productive climate in the past than today, especially in Mesopotamia and the Nile valley.

Situated between the Arabian Desert to the south and the mountains of the Armenian Highland to the north, it extends from Babylonia and adjacent Elam (the southwestern province of Persia, also called Susiana) up the Tigris and Euphrates rivers to Assyria.

From the Zagros Mountains east of Assyria it continues westward over Syria to the Mediterranean and extends southward to southern Palestine.

The Nile valley of Egypt is often included as a further extension, especially since the short interruption in Sinai is no greater than similar desert breaks that disturb its continuity in Mesopotamia and Syria.

Today the Fertile Crescent region has been devastated by dams on the Tigris and the Euphrates rivers, lower rainfall, and decades of armed conflict.
