Egypt and the Nile Valley

A country that lives on a ribbon

Look at Egypt from orbit at night and the shape is unmistakable: a bright thread running north from Aswan, flaring into a glowing fan at the Mediterranean. That thread is the Nile, and almost everyone in Egypt lives on it or beside it. The rest of the country, more than nine tenths of its land, is open desert where rain may not fall for years.

This is geography at its most decisive. A farm field and a sand dune can sit a few meters apart, divided by the reach of an irrigation canal. Cities, roads, railways and villages crowd the same narrow strip, which is why the valley is one of the most densely settled farming landscapes on Earth.

The flood that built a civilization

For thousands of years the Nile rose every summer, fed by monsoon rain falling on the Ethiopian Highlands far to the south. The water spread over the valley floor, then drained away and left a layer of dark, fertile silt. Ancient Egyptians called their land Kemet, the black land, after that soil, and they timed their calendar, taxes and harvests to the flood.

The pyramids of Giza, the temples of Luxor and the tombs of the Valley of the Kings all sit at the edge where green meets desert. Builders put the living on the fertile floodplain and the dead on the dry, rocky ground just beyond it, which helps explain why so much survived.

Taming the river

The Aswan High Dam, finished in 1970, ended the yearly flood. It created Lake Nasser, one of the largest reservoirs in the world, supplied hydropower and allowed farmers to grow crops year round. The trade-off is that silt now settles behind the dam instead of renewing the fields, so farms rely on fertilizer and the delta coastline is slowly retreating.

Today Egypt depends on the Nile for nearly all of its fresh water, and the river's future is a major diplomatic issue. Ethiopia's Grand Ethiopian Renaissance Dam on the Blue Nile, upstream, has been a point of tension for more than a decade.

Planning a visit

The most comfortable months are October through April, when days in Luxor and Aswan are warm rather than scorching. A classic route links Cairo and Giza with a cruise or train south to Luxor and Aswan, where you can sail on a felucca at sunset and visit the temples of Abu Simbel near the Sudanese border.

Summer is quieter and cheaper but brings heat that regularly passes 40 °C in the south. Whatever the season, carry water, start sightseeing early and save the middle of the day for shade, just as Egyptians have always done.
