Deforestation over the centuries has damaged the island's drainage system and made access to a year-round supply of water difficult. A network of winter rivers rises in the Troodos Mountains and flows out from them in all directions. The Yialias River and the Pedhieos River flow eastward across the Mesaoria into Famagusta Bay the Serraghis River flows northwest through the Morphou plain. All of the island's rivers, however, are dry in the summer. An extensive system of dams and waterways has been constructed to bring water to farming areas.

The Mesaoria is the agricultural heartland of the island, but its productiveness for wheat and barley depends very much on winter rainfall other crops are grown under irrigation. Little evidence remains that this broad, central plain, open to the sea at either end, was once covered with rich forests whose timber was coveted by ancient conquerors for their sailing vessels. The now-divided capital of the island, Nicosia, lies in the middle of this central plain.
