Rising sea levels are among the most visible consequences of climate change: water advances into coastal areas, floods fields and alters their composition, gradually increasing soil salinity. For agriculture, this phenomenon translates into smaller harvests and the loss of traditional crops. Among the areas most affected by rising sea levels is the Nile Delta in Egypt. This fertile floodplain, which since the time of the ancient Egyptians has been the cradle of large-scale agriculture, today accounts for two-thirds of the country’s cultivated land. Yet its very low-lying position makes it vulnerable: seawater infiltrates the fields, damaging the roots and reducing productivity.
