Rapid population growth and expanding cities are eating away at one of Egypt’s most precious resources.
During the time of the pharaohs, the fertile soils along the Nile River likely supported a civilization of roughly 3 million people. Now there are 30 times that number of people living in Egypt, with 95 percent of them clustered in towns and cities in the Nile’s floodplain. Much of the growth has come in recent decades, with the Egyptian population soaring from 45 million in the 1980s to more than 100 million now.
Just 4 percent of Egypt’s land is suitable for agriculture, and that number is shrinking quickly due to a wave of urban and suburban development accompanying the population growth. “It’s not an exaggeration to say that this is a crisis,” said Nasem Badreldin, a digital agronomist at the University of Manitoba. “Satellite data shows us that Egypt is losing about 2 percent of its arable land per decade due to urbanization, and the process is accelerating. If this continues, Egypt will face serious food security problems.”
The pair of Landsat images below shows how much farmland has been lost to development around the city of Alexandria between the 1980s and 2021. Cultivated areas appear green; towns and cities are gray. According to one analysis of Landsat observations, the amount of land near Alexandria devoted to agriculture dropped by 11 percent between 1987 and 2019, while urban areas increased by 11 percent.
