In Nile Delta, Sea Encroaching At Up To 100 Meters/Year - Salt, Pollution Hammering Land & Farmers

[hatrack]

Maged Shamdy's ancestors arrived on the shores of Lake Burrulus in the mid-19th century. In the dusty heat of Cairo at the time, French industrialists were rounding up forced labour squads to help build the Suez Canal, back-breaking labour from which thousands did not return. Like countless other Egyptians, the Shamdys abandoned their family home and fled north into the Nile Delta, where they could hide within the marshy swamplands that fanned out from the great river's edge. As the years passed, colonial rulers came and went. But the Shamdys stayed, carving out a new life as farmers and fishermen on one of the most fertile tracts of land in the world. A century and a half later, Maged is still farming his family's fields. In between taking up the rice harvest and dredging his irrigation canals, however, he must contemplate a new threat to his family and livelihood, one that may well prove more deadly than any of Egypt's previous invaders. "We are going underwater," the 34-year-old says simply. "It's like an occupation: the rising sea will conquer our lands."

Maged understands better than most the menace of coastal erosion, which is steadily ingesting the edge of Egypt in some places at an astonishing rate of almost 100m a year. Just a few miles from his home lies Lake Burrulus itself, where Nile flower spreads all the way out to trees on the horizon. Those trunks used to be on land; now they stand knee-deep in water.

Maged's imperial imagery may sound overblown, but travel around Egypt's vast, overcrowded Delta region and you hear the same terms used time and again to describe the impact climate change is having on these ancient lands. Egypt's breadbasket is littered with the remnants of old colonisers, from the Romans to the Germans, and today its 50 million inhabitants jostle for space among the crumbling forts and cemeteries of those who sought to subjugate them in the past. On the Delta's eastern border, in Port Said, an empty stone plinth is all that remains of a statue of Ferdinand de Lesseps, the man who built the Suez Canal; somewhere along the Delta's westernmost reaches, the long-lost tomb of Cleopatra lies buried. With such a rich history of foreign rule, it's only natural that the latest hostile force knocking at the gates should be couched in the language of occupation.

On a tour of his fields, I see why. The rich brown soil has greyed out in recent years, leaving a barren salt-encrustation on the surface. The cause is underground saltwater intrusion from the nearby coast, which pushes up through the soil and kills off roots. Coastal farmland has always been threatened by saltwater, but salinity has traditionally been kept at bay by plentiful supplies of fresh water gushing over the soil and flushing out the salt. It used to happen naturally with the Nile's seasonal floods; after the construction of Egypt's High Dam in the 70s (one of the most ambitious engineering projects on earth), these seasonal floods came to an end, but a vast network of irrigation canals continued to bring gallons of fresh water to the people who worked the land, the fellahin, ensuring salinity levels remained low. Today, however, Nile water barely reaches this corner of the Delta. Population growth has sapped its energy upstream, and what "freshwater" does make it downriver is increasingly awash with toxins and other impurities. Farmers such as Maged now essentially rely on waste water – a mix of agricultural drainage and sewage – from the nearby town of Sidi Salim. The result is plummeting fertility; local farmers say that whereas their fathers spent just a handful of Egyptian pounds on chemicals to keep the harvests bountiful, they now have to put aside between 25 and 80% of their profits for fertilisers just to keep their crops alive.
