There's also a page on Egypt but it says little more than what you'd find in any encyclopedia although it is quite wrong about the yearly flooding cycle unless of course the two Aswan dams are destroyed (but it does not mention anything about the dams). With the dams in place, Egypt relies heavily on fertilizers to keep its agricultural production up as the dams prevent fresh soil from flushing down to the floodplains and renewing the fertility of the farmlands.
