Nile threatened by waste, warming, dam

EARLY one morning in Cairo, volunteers paddle their kayaks across the Nile, fishing out garbage from the mighty waterway that gave birth to Egyptian civilization but now faces multiple threats.

Egypt’s lifeline since Pharaonic days and the source of 97 percent of its water is under massive strain from pollution and climate change and now the threat of a colossal dam being built far upstream in Ethiopia. Undeterred, the flotilla of 300 environmental activists do what they can — in the past three years they say they have picked some 37 tons of trash from the Nile waters and shores.

“People have to understand that the Nile is as important — if not more — than the pyramids,” said Mostafa Habib, 29, co-founder of the environmental group Very Nile. “The generations coming after us will depend on it.”

His fears echo those that millions worldwide share about other over-taxed and polluted rivers from the Mekong to the Mississippi — an issue marked on World Water Day on March 22.

But few waterways face greater strain than the 6,600-kilometer Nile, the basin of which stretches across 11 countries: Burundi, Democratic Republic of Congo, Egypt, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania and Uganda. No country is more reliant on the Nile than Egypt, whose teeming population has just passed 100 million people — over 90 percent of whom live along the river’s banks.

Surrounded by a green valley full of palm trees, the north-flowing river is awash with boats of all sizes for tourism, fishing and leisure.

“All of us Egyptians benefit from the Nile, so cleaning it up is a way of giving back to my country,” said volunteer Walied Mohamed, a 21-year-old student. “The Nile is the main source of drinking water for Egypt. We have no other major rivers flowing in our country.”

Despite its importance, the Nile is still heavily polluted in Egypt by waste water and rubbish poured directly into it, as well as agricultural runoff and industrial waste, with consequences for biodiversity, especially fishing and human health. Around 150 million tons of industrial waste are dumped into it every year, according to the state-run Environmental Affairs Agency.

Climate change spells another threat as rising sea levels are set to push Mediterranean salt water deep into the fertile Nile river delta. Researchers predict the country’s already stretched agricultural sector could shrink by as much as 47 percent by 2060 as a result of saltwater intrusion. Cotton, one of the most widely cultivated plants along the Nile, requires a lot of water. Egypt also faces a nationwide fresh water shortage by 2025.

Already around 7 percent of Egyptians lack access to clean drinking water and over 8 million go without proper sanitation. Hydrologists say people face water scarcity when their supply drops below 1,000 cubic meters per person annually. Egyptian officials say in 2018 the individual share was 570 cubic meters and that this is expected to further drop to 500 cubic meters by 2025.

But aside from all the existing threats, there is another issue that terrifies Egypt’s national planners and has even sparked fears of war. More than 3,000 kilometers upstream on the Blue Nile, the main tributary, thousands of workers have toiled for a decade to build the US$4.5-billion Grand Ethiopian Renaissance Dam, set to be Africa’s largest.

Downstream countries, mainly Egypt but also drought-plagued Sudan, fear that the dam’s 145-meter-high wall will trap their essential water supplies once the giant reservoir, the size of London, starts being filled this summer.

Years of tensions between Cairo, Khartoum and Addis Ababa have even seen Washington jump in to mediate rounds of crisis diplomacy. For Ethiopia, one of Africa’s fastest-growing economies, the dam is a prestige project and source of national pride.

In a country of 110 million where even the capital is plagued by blackouts, it promises to provide electricity by 2025 to more than half of the population that now lives without it.

Ethiopian Prime Minister Abiy Ahmed has insisted the project will not be stopped, warning that if necessary “we can deploy many millions.”

In less belligerent but equally dramatic language, Egyptian President Abdel Fattah al-Sisi told the United Nations last year that “the Nile is a question of life, a matter of existence to Egypt.”

For some farmers in Sudan, the dam promises to tame rainy season floods that inundate farms with silt and destroy crops and houses.

One Blue Nile farmer Osman Idris said “it’s a renegade river, it rises so fast.”

If its flow is regulated, “we can plant crops through the year,” the 60-year-old farmer said. “It will be better for the environment and marketing our products, which means more income for us.”

For Egypt, the crucial question now is at what rate Ethiopia plans to fill the 74-billion-cubic-meter reservoir — Cairo demands it at least triple its proposed period of three to four years. But experts also warn that Egypt must change its own water management practices.

“Egypt needs to invest in non-Nile sources of water,” said Jeannie Sowers, a political science professor at University of New Hampshire who authored a book on Egypt’s environmental policies. “This means prioritizing desalination plants on the coasts and improving irrigation and drainage networks.”
