Why did Akbar change his capital from Fatehpur Sikri?

Akbar built the city of Fatehpur Sikri in Agra, India, in honor of Shaikh Salim Chishti between 1571-1585. It served as the capital of the Mughal Empire from 1571-1585. Due to inadequate water supplies, it was abandoned. In 1585 Lahore became the capital. In 1599, Akbar again shifted his capital back to Agra.
