Nile is in mortal danger, from its source to the sea

The pharaohs worshipped it as a god, the
eternal bringer of life. But the clock is ticking on the Nile.
Climate change, pollution, and exploitation by man
are putting existential pressure on the world’s second-longest river, on which
half a billion people depend for survival.
All along its 6,500km length, alarm bells are
ringing.
From Egypt to Uganda, AFP teams have gone out on the
ground to gauge the decline of a river that drains a tenth of the African
continent.

At its mouth on the Mediterranean, Sayed Mohammed is
watching Egypt’s fertile Nile Delta disappear. In Sudan, fellow farmer Mohammed
Jomaa fears for his harvests, while at its threatened source in Uganda, there
is less and less hydroelectric power for Christine Nalwadda Kalema to light her
mud and wattle home.
“The Nile is the most important thing for us,” said
Jomaa, who at 17 is the latest generation of his family to work the river’s
rich banks at Alty in Gezira state, Sudan.
“We certainly do not wish for anything to change,”
he said.
But the Nile is no longer the unperturbable river of
myth. In half a century its flow has dropped from 3,000 cubic meters per second
to 2,830 cubic meters.

Yet it could get much, much worse. With multiple
droughts in east Africa, its flow could fall by 70 percent, according to the
UN’s most dire predictions.
Every year for the past six decades, the
Mediterranean has eaten away between 35m and 75m of the Nile Delta. If the sea
level rises even by a meter, a third of this intensely fertile region could
disappear, the UN fears, forcing nine million people from their homes.
What was once a bread basket has become the third
most vulnerable place on the planet to climate change.
Lake Victoria, the Nile’s biggest source of water
after rainfall, could also dry up due to drought, evaporation, and slow tilts
in the Earth’s axis.
With such grim scenarios in store, governments have
scrambled to capture its flow. But experts say dams are only hastening the
coming catastrophe.

Land lost to sea
At the mouth of the Nile,
the promontories of Damietta and Rosetta that once stuck out into the
Mediterranean in northern Egypt have disappeared.
The concrete barriers that were supposed to protect
them are half covered by water and sand.
The sea ate 3km into the Nile Delta between 1968 and
2009, with the river’s weaker flow unable to hold back the Mediterranean, which
rose some 15cm over the last century due to climate change.
The silt that for millennia formed a barrier to
protect the land no longer makes it to the sea. This rich dark sediment that
was once swept along the river’s bed has struggled to get beyond southern Egypt
since the Aswan dam was built in the 1960s to regulate the Nile’s floods.

Before its construction “there was a natural
balance”, Ahmed Abdel Qader, the head of Egypt’s coast protection authority,
told AFP. “Every Nile flood would deposit silt bulking up the promontories at
Damietta and Rosetta. But this balance has been disturbed by the dam,” he said.
If temperatures keep rising, the Mediterranean will
advance a further 100m a year into the Delta, the UN’s environment agency UNEP
has warned.
Poisoned by salt
Fifteen kilometers inland,
the bustling farming community of Kafr El-Dawar seems as yet far from danger.
But all is not well, said Sayed Mohammed, 73, who
supports his 14 children and grandchildren growing rice and corn in fields
sandwiched between the Nile and a road cacophonous with car horns.
Salt from the Mediterranean has already seeped into
large swathes of land, killing and weakening plants. Farmers say their
vegetables no longer taste the same. To compensate for the salination of the
soil, they have to pump more fresh water onto it from the Nile.

For 40 years Mohammed and his neighbors used pumps
that guzzled diesel and electricity. The cost strangled villagers whose income
was already being eaten up by inflation and devaluations of the Egyptian pound.
So much so that in some parts of the Delta, fields were abandoned.
But the old man, who sports a djellaba and a
traditional woolen cap, has been helped by a new irrigation system driven by
solar energy which aims to increase farmers’ incomes to stop more people
fleeing the land. Thanks to the 400 solar panels the UN’s Food and Agriculture
Organization financed for Kafr El-Dawar, he can water his half hectare of
ground.
Solar power saves “farmers about 50 percent” of
pumping costs, local irrigation chief Amr Al-Daqaq told AFP. And they can also
sell the surplus power the panels produce to the national grid.
Even so, none of Mohammed’s descendants want to take
on the farm. For the Mediterranean may eventually swallow up 100,000 hectares
of the region’s prime agricultural land, according to UNEP, covering an area
nearly 10 times the size of Paris.
This would be a disaster for Egypt, with the Delta
the source of between 30 and 40 percent of the nation’s agricultural output.
Power cuts
All but three percent of
Egypt’s 104 million people live along the river on just eight percent of the
country’s territory. It is a similar story in neighboring Sudan, with half its
45 million people living along its banks, and the Nile supplying two-thirds of
its water.
By 2050, the population of both countries will have
doubled, and it will be two or three degrees hotter.

The UN’s group of climate experts, the IPCC, say the
impact on the Nile will be catastrophic. They predict it will lose 70 percent
of its flow by the end of the century, with the water supply available to every
person along it plummeting to a third of what they have now.
Floods and other violent storms likely to lash East Africa as the climate warms will only make up 15 to 25 percent of that lost
water, the IPCC has warned. This will leave the 10 countries that rely on the
Nile for their crops and power in dire straits.
More than half of Sudan’s power comes from
hydroelectricity, with 80 percent of Uganda’s power generated from the river.
It is thanks to the Nile that Christine Nalwadda Kalema, a 42-year-old single
mother, can light her humble shop and home in a poor part of the village of
Namiyagi near Lake Victoria in Uganda.
Source threatened
But the electricity that
radically changed her life in 2016 may not last, said Revocatus Twinomuhangi,
from Makerere University’s Center for Climate Change in Kampala.
“If we have a reduction in rainfall ... it will
translate into reduced hydroelectric power potential,” he said. Already over
“the last five to 10 years we have seen an increase in the frequency and
intensity of drought, intense rainfall and flooding, and also heat intensity,
so it is becoming hotter and hotter”.
Indeed, Lake Victoria could disappear entirely
within the next 500 years, according to a study by British and American
scientists based on geological data from the last 100,000 years.
But for Kalema, who grows bananas, manioc, and
coffee in her little garden to feed her family, such statistics remain
abstract. What concerns her are more and more frequent power cuts.
“Because of the cuts my son struggles to keep up
with his homework. He has to read before nightfall,” she said, dressed in
colorful local “kitenge” cloth. “Candles are very expensive to me as a single
mother with limited income.”
Mega dams
More than half of Ethiopia’s
110 million people have no choice but to live without electricity, despite the
country’s having one of the fastest growth rates in Africa.
Addis Ababa is hoping that its GERD mega-dam project
on the Nile will remedy that, and is ready to burn bridges with its neighbors
if it has to.
Begun in 2011, the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile — which joins the White Nile in Sudan to form the Nile
— already holds nearly a third of its 74-billion-cubic-meter capacity.
Addis Ababa claims it is the biggest hydroelectric
project in Africa.
“The Nile is a gift of God given to us for
Ethiopians to make use of it,” Prime Minister Abiy Ahmed insisted in August.
But for Cairo, the dam is a major headache, calling
into question a deal signed with Sudan in 1959 which gave 66 percent of the
Nile’s annual flow to Egypt and 22 percent to Khartoum.
Although Ethiopia was not part of the accord,
advisers to former Egyptian president Mohamed Morsi publicly floated bombing
the dam back in 2013 to protect Cairo’s vital interests.
The Egypt of President Abdel Fattah Al-Sissi still
fears a drastic fall in the Nile’s flow because of the GERD. And how much water
Egypt is losing has sparked a heated debate within the scientific community,
with some Egyptian researchers who minimize the effects facing accusations of
“betraying” their country.
Disappearing silt
Meanwhile, having already
seen how the Aswan dam has reduced the flow of silt, farmers worry about being
deprived of this precious natural fertilizer.
Over the years, Sudanese farmer Omar Abdelhay has
found it harder and harder to grow cucumbers, eggplants, and potatoes in his
luxuriantly green fields watered by the brown Nile water that passes close by
his mud-brick home.
Eight years ago, when this 35-year-old father began
to cultivate his family’s land, “there was good silt” to nurture his crops, he
told AFP. But little by little as dam-building has increased, “the water has
got clearer. Even if the water level rises” during floods, it “comes without
silt”, he added.
Stuck in a political and economic slump, and with ongoing
protests against its military leaders, Sudan is struggling to manage its water
resources.
Stalked by hunger
Every year, the country is
lashed by rainstorms that this summer killed 150 people and washed away entire
villages. But the deluges are no help to its agriculture because of the lack of
a system to store and recycle rainwater.
Famine now threatens a third of its people despite
Sudan long being a major player in world markets for peanuts, cotton, and gum
arabic.
Modest irrigation canals built during the colonial
era mean even a small flow is enough to water its fertile land. But the
development of this system through the Gezira Scheme has been long delayed.
Vast fields cultivated under the corrupt command
economy of dictator Omar Al-Bashir, who was overthrown in 2019, have fallen
fallow, and in their place, families grow peppers and cucumbers on small
parcels of land.
Sudan, like other countries along the Nile — and
many other east African states — is near the bottom of Notre Dame University’s
GAIN rankings, which measure resilience to climate change.
For Callist Tindimugaya, of Uganda’s ministry of
water and the environment, rising temperatures will impact not just the
country’s ability to feed itself, but also its capacity to generate electricity
to power homes and industry.
“Short heavy rains can cause flooding. Long dry
periods will bring loss of water. ... And you cannot survive without water,”
Tindimugaya said.

And how much water Egypt is losing has sparked a heated debate within the scientific community, with some Egyptian researchers who minimize the effects facing accusations of “betraying” their country.
Disappearing silt
Meanwhile, having already seen how the Aswan dam has reduced the flow of silt, farmers worry about being deprived of this precious natural fertilizer.
Over the years, Sudanese farmer Omar Abdelhay has found it harder and harder to grow cucumbers, eggplants, and potatoes in his luxuriantly green fields watered by the brown Nile water that passes close by his mud-brick home.
Eight years ago, when this 35-year-old father began to cultivate his family’s land, “there was good silt” to nurture his crops, he told AFP.

Every year, the country is lashed by rainstorms that this summer killed 150 people and washed away entire villages. But the deluges are no help to its agriculture because of the lack of a system to store and recycle rainwater.
Famine now threatens a third of its people despite Sudan long being a major player in world markets for peanuts, cotton, and gum arabic.
Modest irrigation canals built during the colonial era mean even a small flow is enough to water its fertile land. But the development of this system through the Gezira Scheme has been long delayed.
Vast fields cultivated under the corrupt command economy of dictator Omar Al-Bashir, who was overthrown in 2019, have fallen fallow, and in their place, families grow peppers and cucumbers on small parcels of land.
Sudan, like other countries along the Nile — and many other east African states — is near the bottom of Notre Dame University’s GAIN rankings, which measure resilience to climate change.

For Callist Tindimugaya, of Uganda’s ministry of water and the environment, rising temperatures will impact not just the country’s ability to feed itself, but also its capacity to generate electricity to power homes and industry.
“Short heavy rains can cause flooding. Long dry periods will bring loss of water. ... And you cannot survive without water,” Tindimugaya said.
