All of us now live on one hell (and I do mean hell) of a planet. Just imagine this: June, July, August, September, October, November, December — each was a record-shattering month of heat in 2023, which, not surprisingly, proved to be a record-shattering year. Month by month, humanity had never experienced the likes of it. And January 2024 set the latest monthly heat record not just for the land, but for the oceans, too.

Now, let me go Trumpian for a moment and replace his “drill, drill, drill” (on Day 1 of his future “dictatorship” — oops, sorry, I meant presidency) with “heat, heat, heat.” Of course, were he to win the upcoming election, he undoubtedly would do his damnedest to turn this world of ours into an all too literal hellhole of fossil-fuel use.

Unfortunately, despite its recent record extremes, climate change is, in a sense, hard to take in. It’s a remarkably ongoing global phenomenon that doesn’t tend to bombard us with headlines like the nightmare in Gaza or Joe Biden’s “well-meaning, elderly” charm or Donald Trump’s potential offer to the Russians to do “whatever the hell they want” when it comes to certain countries in Europe. It’s generally in the background, even as records are broken, then broken again, and again and again and… well, you get the point. After all, for the first time ever, last year’s global heat may even have breached the barrier set up in the 2015 Paris climate accord of 1.5 degrees Centigrade above the pre-industrial average. (If not, it came awfully close.) Meanwhile, from unparalleled rainstorms and floods to unparalleled fires, this planet and all of us on it are experiencing something new.

In the context of that newness — in a world where rivers are drying up — things that once were a given no longer are. In today’s case, let TomDispatch regular Joshua Frank, author of Atomic Days: The Untold Story of the Most Toxic Place in America, help us think about what it means to build giant dams across the planet. And while you’re at it, keep in mind that we’re all now living in a world that, not so long ago, would have seemed unbelievable — and that in some cases, like drill, drill, drill, build, build, build may not be the dream formula it once was.

Dam, Dam, Dam!
Is There a Place for Hydropower in a Warming World?

We live in a world of dangerous, deadly extremes. Record-breaking heat waves, intense drought, stronger hurricanes, unprecedented flash flooding. No corner of the planet will be spared the wrath of human-caused climate change and the earth’s fresh water is already feeling the heat of this new reality. More than half of the world’s lakes and two-thirds of its rivers are drying up, threatening ecosystems, farmland, and drinking water supplies. Such diminishing resources are also likely to lead to conflict and even, potentially, all-out war.

“Competition over limited water resources is one of the main concerns for the coming decades,” warned a study published in Global Environmental Change in 2018. “Although water issues alone have not been the sole trigger for warfare in the past, tensions over freshwater management and use represent one of the main concerns in political relations between… states and may exacerbate existing tensions, increase regional instability and social unrest.”

The situation is beyond dire. In 2023, it was estimated that upwards of three billion people, or more than 37% of humanity, faced real water shortages, a crisis predicted to dramatically worsen in the decades to come. Consider it ironic then that, as water is disappearing, huge dams — more than 3,000 of them — that require significant river flow to operate are now being built at an unprecedented pace globally. Moreover, 500 dams are being constructed in legally protected areas like national parks and wildlife reserves. There was a justification for this, claimed the U.N.’s Intergovernmental Panel on Climate Change (IPCC) some years ago. Such projects, it believed, would help battle climate change by curbing carbon dioxide emissions while bringing electricity to those in the greatest of need.

“[Hydropower] remains the largest source of renewable energy in the electricity sector,” the IPCC wrote in 2018. “Evidence suggests that relatively high levels of deployment over the next 20 years are feasible, and hydropower should remain an attractive renewable energy source within the context of global [greenhouse gas] mitigation scenarios.”

The IPCC acknowledged that unceasing droughts impact stream flow and that climate change is unpredictably worsening matters. Yet its climate experts still contended that hydropower could be a crucial part of the world’s energy transition, arguing that an electric dam will produce seemingly endless energy. At the same time, other renewable sources like wind and solar power have their weather- and sunlight-bound limitations.

A Crack in the Dam Logic

Well-intentioned as it may have been, it’s now far clearer that there is a crack in the IPCC’s appraisal. For one thing, recent research suggests that hydro-powered dams can create an alarming amount of climate-altering greenhouse gas emissions. Rotting vegetation at the bottom of such reservoirs, especially in warmer climates (as in much of Africa), releases significant amounts of methane, a devastating greenhouse gas, into the atmosphere.

“Most of this vegetation would have rotted anyway, of course. But, without reservoirs, the decomposition would occur mostly in the atmosphere or in well-oxygenated rivers or lakes,” explains Fred Pearce in the Independent. “The presence of oxygen would ensure the carbon in the plants formed carbon dioxide. But many reservoirs, particularly in the tropics, contain little oxygen. Under those anaerobic conditions, rotting vegetation generates methane instead.”

While CO2 also seriously harms the climate, methane emissions are far worse in the short term.

“We estimate that dams emit around 25% more methane by unit of surface than previously estimated,” says Bridget Deemer of the School of Environment at Washington State University in Vancouver, lead author of a highly-cited study on greenhouse gas emissions from reservoirs. “Methane stays in the atmosphere for only around a decade, while CO2 stays several centuries, but over the course of 20 years, methane contributes almost three times more to global warming than CO2.”

And that’s hardly the only problem dams face in the twenty-first century. At the moment, Chinese financing is the most significant global driver of new hydropower construction. China has invested in the creation of at least 330 dams in 74 countries. Each project poses its own set of environmental quandaries. But above all, the heating of the planet — last year was the warmest in human history and January 2024 the hottest January on record — is making many of those investments look increasingly dubious. On this ever-hotter globe of ours, for instance, a drought in Ecuador has all too typically impacted the functionality of the Amaluza Dam on the Paute River, which provides 60% of that country’s electricity. Paute was running at 40% capacity recently as its river flow dwindled. Similarly, in southern Africa, water levels at the Kariba Dam’s reservoir, located between Zambia and Zimbabwe, have fluctuated drastically, impairing its ability to produce consistent energy.

“In recent years, drought intensified by climate change has caused reservoirs on all five continents⁠ to drop below levels needed to maintain hydroelectric production,” writes Jacques Leslie in Yale E360, “and the problem is bound to worsen as climate change deepens.”

Even in the United States, the viability of hydropower is an increasing concern. The Hoover Dam on the Colorado River, for example, has been impacted by years of drought. Water levels at its reservoir, Lake Mead, continue to plummet, raising fears that its days are numbered. The same is true for the Glen Canyon Dam, which also holds back the Colorado, forming Lake Powell. As the Colorado dries up, Glen Canyon may also lose its ability to produce electricity.

Driven by dwindling water resources, the global hydropower crisis has become a flashpoint in the far reaches of Northern Africa, where the creation of a giant dam could very well lead to a regional war and worse.

A Crisis on the Nile

The lifeblood of northeastern Africa, the Nile River, flows through 11 countries before emptying into the Mediterranean Sea. Measured at 6,650 kilometers, the Nile may be the longest river on Earth. For millennia, its meandering waters, which run through lush jungles and dry deserts, have been irrigating farmlands and providing drinking water for millions of people. Nearly 95% of Egypt’s 109 million people live within a few kilometers of the Nile. Arguably the most important natural resource in Africa, it’s now at the epicenter of a geopolitical dispute between Egypt, Ethiopia, and Sudan that’s brought those countries to the brink of military conflict.

A major dam being built along the Blue Nile, the river’s main tributary, is upending the status quo in the region, where Egypt has long been the preeminent nation. The Grand Ethiopian Renaissance Dam (GERD for short) is to become one of the largest hydroelectric dams ever constructed, stretching more than 1,700 meters and standing 145 meters tall, a monument many will love and others despise.

There’s no question that Ethiopia needs the electricity GERD will produce. Nearly 45% of all Ethiopians lack regular power and GERD promises to produce upwards of 5.15 gigawatts of electricity. To put that in perspective, a single gigawatt would power 876,000 households annually in the United States. Construction on the dam, which began in 2011, was 90% complete by last August when it began producing power. In total, GERD’s cost is expected to eclipse $5 billion, making it the largest infrastructure project Ethiopia has ever undertaken and the largest dam on the African continent.

It will not only bring reliable power to that country but promises a culture shift welcomed by many. “Mothers who’ve given birth in the dark, girls who fetch wood for fire instead of going to school — we’ve waited so many years for this — centuries,” says Filsan Abdi of the Ethiopian Ministry of Women, Children, and Youth. “When we say that Ethiopia will be a beacon of prosperity, it starts here.”

While most Ethiopians may see the dam in a positive light, the downstream countries of Egypt and Sudan (itself embroiled in a devastating civil war) were never consulted, and their officials are indignant. The massive reservoir behind GERD’s gigantic cement wall will hold back 74 billion cubic meters of water. That means Ethiopia will have remarkable control over the flow of the Nile, giving its leaders power over how much access to water both Egyptians and Sudanese will have. The Blue Nile, after all, provides 59% of Egypt’s freshwater supply.

As it happens, fresh water in Egypt has long been growing scarcer and so the country’s leadership has taken the threat of GERD seriously for years. In 2012, for instance, Wikileaks obtained internal emails from the “global intelligence” firm Stratfor revealing that Egypt and Sudan were even then considering directing the Egyptian Special Forces to destroy the dam, still in the early stages of construction. “[We] are discussing military cooperation with Sudan,” a high-level Egyptian source was quoted as saying. While such a direct attack never transpired, Stratfor claimed that Egypt might once again lend support to “proxy militant groups against Ethiopia” (as it had in the 1970s and 1980s) if diplomacy were to hit a dead end.

Unfortunately, the most recent negotiations to calm the hostility around GERD have gone distinctly awry. Last April, the embittered Egyptians responded to the lack of any significant progress by conducting a three-day military drill with Sudan at a naval base in the Red Sea aimed at frightening Ethiopian officials. “All options are on the table,” warned Egyptian Foreign Minister Sameh Shoukry. “[All] alternatives remain available and Egypt has its capabilities.”

Seemingly unfazed by such military threats, Ethiopia plans to finish building the dam, claiming it will provide much-needed energy to impoverished Ethiopians and limit the country’s overall carbon footprint. “[GERD] represents a sustainable socio-economic project for Ethiopia: replacing fossil fuels and reducing CO2 emissions,” the Ethiopian embassy in Washington has asserted.

GERD, however, falls squarely into the category of being a major problem dam — and not just because it could lead to a bloody war in a region already in horrific turmoil. Once filled, its massive reservoir will cover a staggering 1,874 square kilometers, making it more than three-quarters the size of Utah’s Great Salt Lake (after it started to shrink).

Unfortunately, GERD never underwent a proper environmental impact assessment (EIA) despite being legally required to do so. No EIA was ever carried out because the notoriously corrupt Ethiopian government knew that the results wouldn’t be pleasing and was unwilling to let any roadblocks get in the way of the dam’s construction, something that became more obvious when upwards of 20,000 indigenous Gumuz and Berta natives began to be forced from their homes to make way for the monstrous dam.

Publicly coming out against the dam has proven a risky business. Employees of International Rivers, a nonprofit that advocates for people endangered by dams, have been harassed and received death threats in response to their opposition. Prominent Ethiopian journalist Reeyot Alemu, a critic of the dam and the government’s actions concerning it, was imprisoned for more than four years under draconian anti-terrorism laws.

Electric Water Wars

While GERD has created a dicey conflict, it also has international ramifications. China, which has played such a pivotal role in bankrolling hydropower projects globally in these years, has provided $1.2 billion to help the Ethiopians build transmission lines from the dam to nearby towns. Since it has also heavily invested in Egypt, it’s well-positioned, if any country is, to help navigate the GERD dispute.

Military analysts in the United States argue that China’s involvement with the dam is part of a policy meant to put the U.S. at a distinct disadvantage in the race to exploit Africa’s abundant rare earth minerals from the cobalt caverns of the Congo to the vast lithium deposits in Ethiopia’s hinterlands. China, the world’s “largest debt collector,” has indeed poured money into Africa. As of 2021, it was that continent’s largest creditor, holding 20% of its total debt. The growth of Chinese influence internationally and in Africa — it has large infrastructure projects in 35 African countries — is crucial to understanding the latest version of the globe’s imperial geopolitics.

Most of China’s African ventures are connected to Beijing’s “Belt and Road Initiative,” a program of this century to fund infrastructure deals across Eurasia and Africa. Its economic ties to Africa began, however, with Chinese leader Mao Zedong’s push in the 1950s and 1960s for an “Afro-Asian” alliance that would challenge Western imperialism.

So many decades later, the idea of such an alliance plays second fiddle to China’s global economic desires, which, like so many past imperial projects in Africa, have significant downsides for those on the receiving end. Developing countries desperately need capital, so they’re willing to accept rigid terms and conditions from China, even if they represent the latest version of the century’s old colonialism and neo-colonialism that focused on controlling the continent’s rich resources. This is certainly true in the case of China’s hydropower investments in places like Ghana’s Bui Dam and the Congo River Dam in the Republic of Congo, where multi-billion-dollar loans are backed by Congo’s crude oil and Ghana’s cocoa crops.

In 2020, the U.S. belatedly inserted itself into the GERD feud, threatening to cut $130 million in aid for Ethiopia’s anti-terrorism efforts. The Ethiopians believed it was related to the dam controversy, as they also did when, in June 2023, the Biden administration directed USAID to halt all food assistance to the country (upwards of $2 billion), claiming it wasn’t reaching Ethiopians, only to reverse course months later.

The dispute over Ethiopia’s enormous dam should be a warning of what the future holds on a hotter, drier planet, where the rivers that feed dams like GERD are drying up while the superpowers continue to jockey for position, hoping to control what remains of the world’s resources. Hydropower won’t help solve the climate crisis, but new dam projects may lead to war over one thing key to our survival — access to fresh, clean water.
