Libreria Acqua Alta is Instagram well-known. Greater than 30,000 individuals have tagged themselves visiting the enchanting bookstore, however in contrast to different well-liked buildings in Venice, Libreria Acqua Alta is not a church or canalside palazzo. It is quintessentially Venice in one other manner: It is designed to outsmart the floods which have plagued town for hundreds of years.
Inside you will discover books on Venetian delicacies stacked inside bathtubs. English and Italian fiction titles are wedged beside one another, packed tightly in a gondola stretching from one facet of the cramped store to the opposite. They are not simply there so as to add environment. When the Italian metropolis floods, because it does dozens of occasions a yr, the bathtubs and gondola float, safeguarding the books inside.
Libreria Acqua Alta will get its identify from this phenomenon: Acqua Alta, which implies “excessive water,” refers back to the excessive tides from the Adriatic Sea that blow into the Venetian Lagoon. These floods have been a truth of life for Venice since the fifth century, however resulting from rising sea ranges brought on by local weather change, they now pose a damaging risk.
There have been 34 cases of acqua alta between 2014 and 2018 that exceeded 110 centimeters (43 inches), sufficient to flood chunks of town and trigger continual harm to its infrastructure. There have been simply 30 such occasions between 1875 and 1951.
The town’s residents, historic buildings and irreplaceable artwork are in danger. Some contend Venice itself might be unlivable by the top of the century. A number of options have been proposed, equivalent to pumping water or liquid cement beneath Venice to boost town, in addition to additional fortifying the lagoon’s pure defenses.

As an alternative, the Italian authorities is pondering on a grander scale. It is spent the previous 17 years constructing MOSE, a multibillion-euro infrastructure challenge revolving round 78 remote-controlled gates that may rise when vital to dam excessive tides from coming into the Venetian Lagoon.
On Oct. three, after previously being tested in fair whether, MOSE was used to guard Venice in opposition to an precise acqua alta. It was successful. Whereas tides within the lagoon rose to 120 centimetres, local media reported, Venice itself remained dry. This got here as a shock to Venetian residents.
Beset by corruption and delays, MOSE over the past 17 years has itself has develop into an issue. Critics say that the gates will not be as efficient as the federal government envisions and that they’re going to need to be raised so often that Venice’s sewage might be trapped within the Lagoon, killing off its ecosystem.
“That is the loss of life of Venice,” Fabrizio Antonioli, a geologist at sustainable growth agency ENEA, stated of MOSE earlier this yr.
Although October’s profitable take a look at is an efficient signal, Venetians have motive to stay skeptical. If every thing had gone to plan, the MOSE gates would have been prepared in 2011. However 9 years later, and four billion euros over the unique 1.6 billion ($1.eight billion) euro funds, some fear that MOSE may by no means rise to the problem of saving Venice.

Local weather disaster
Resting on the northern finish of the Adriatic Sea atop 118 islands which might be linked by bridges and separated by canals, Venice is outlined by water. After centuries of Venice ruling parts of the Mediterranean Sea as a maritime energy, town’s iconic canals now entice round 20 million vacationers a yr. But the water that protected its first settlers from invasions has develop into town’s most troubling legal responsibility. A excessive tide and a powerful wind from the ocean, blowing the Adriatic’s water into the shallow lagoon, is all that is wanted to flood Venice’s decrease districts.

Like Libreria Acqua Alta, Venice is designed to work with flooding. Electrical junction packing containers are saved the place even the very best of tides cannot attain. Elevated wood walkways, or “duckboards,” are arrange shortly to attach buildings when sidewalks are submerged. Gondolas are designed in order that their heads could be eliminated (and later reattached) to make sure secure passage beneath bridges as water ranges rise. However final yr one massive acqua alta arrived so shortly town had no time to react.
“It began out of the blue,” recollects Diana Zamda, an worker at Libreria Acqua Alta. “I’ve by no means seen something like that.” All it took was “40 or 50 minutes” for a traditional day in Venice to transition into chaos.
Zamda is describing Nov. 12, 2019, when Venice was ravaged by catastrophic floods. Water rose as excessive as 1.87 meters (6.1 toes), half a meter greater than anticipated, inflicting an estimated $1.1 billion in harm. Historic buildings have been deluged, motels have been shut and two people were killed. And Libreria Acqua Alta’s defenses have been overwhelmed, with tons of of books broken or misplaced.

Just one flood within the metropolis’s recorded historical past was extra damaging than 2019’s, again in 1966. A 1.94-meter acqua alta, generally known as the Acqua Granda, ravaged town. Hundreds of residents have been pressured to evacuate their houses, an estimated 75% of shops have been broken and $3 billion in artwork was lost.
Since then, Venice’s inundations have skyrocketed with no signal of abating. St. Mark’s Sq., town’s historic and vacationer centerpiece, flooded lower than 10 occasions a yr within the first decade of the 20th century. In each of the past five years, it’s flooded 60 times.

Venice’s floods aren’t brought on by local weather change, however international warming is a significant component. Simply as local weather change provokes bushfires in Australia by worsening preexisting circumstances like drought and dry soil, it magnifies Venice’s inherent vulnerability to floods by way of rising sea ranges — from 2.5 millimeters a yr within the 20th century to round 6 millimeters a year in recent decades.
Venice’s methodology of water-level measurement evinces the extent to which local weather change has magnified the difficulty. Base stage, zero centimeters, refers back to the water stage of 1872, when the first tide gauge was installed. When officers word that town begins to flood as sea ranges attain 80 centimeters, they imply 80 centimeters above the 1872 stage. However the sea stage has risen by round 30 centimeters, or 12 inches, within the 150 years since. With this raised sea stage, the brand new unofficial common, tides solely must rise 50 centimeters earlier than components of town start to flood.
Till individuals get up to the truth that MOSE is not going to resolve Venice’s downside, different choices usually are not going to be taken severely.

Native human exercise is exacerbating town’s water woes, too. A post-World Conflict II plot to industrialize a close-by city led to extreme pumping of Venice’s groundwater from the ’50s to the ’70s, inflicting town to sink 12 centimeters and positioning it much more precariously. (And resulting from tectonic exercise, town continues to sink just a few millimeters annually.)
“Flooding of Venice has occurred many occasions throughout its historical past,” wrote Caroline Fletcher and Tom Spencer in their 2005 book on Venice, however “the final 50 years represents an unprecedented interval of frequent and intense occasions.”
Duckboards are saved available for fast building so residents can go about their day throughout delicate floods, which happen dozens of occasions a yr.

Venice’s authorities has been actively combating flood circumstances since 1966’s Acqua Granda. Within the years that adopted, explains Carl Amos, Southampton College’s professor emeritus of earth and ocean sciences, the native authorities bolstered town’s defenses. Canals have been dried out so town’s foundations could possibly be fortified, walkways have been raised to face up to increased tides, and salt marshes and mudflats within the Venetian Lagoon have been cultivated to dam incoming ocean water.
“A variety of the work was accomplished by the municipality of Venice. It was all native,” says Amos, who’s been learning Venice for over 25 years. He stated these renovations, although not spectacular, have been efficient. Sadly, many cures could be enacted solely up to a degree. You’ll be able to increase pavement however not doorways, for instance, so additional elevating walkways would imply residents crouching by way of doorways. (One of many extra generally proposed alternate options to MOSE is to continue working on the Lagoon’s mudflats and salt marshes.)
Within the 1980s, Italy’s nationwide authorities determined it could repair Venice’s water issues as soon as and for all. It conceived a challenge referred to as MOSE, quick for Modulo Sperimentale Elettromeccanico (Electromechanical Experimental Module), and Italian for Moses. It might be named after a biblical determine, however now, nearly 40 years later, many unconvinced that MOSE is the reply to Venice’s prayers.
MOSE woes
The concept sounds believable. MOSE’s 78 cell gates can be constructed alongside the three inlets that join the Adriatic Sea to the Venetian Lagoon. Like London’s Thames Barrier or the Maeslantkering defending Rotterdam from the North Sea, the gates might be remotely erected when tides rise, blocking water from coming into the Lagoon and saving Venice from heavy floods. The gates are then remotely retracted as soon as the ocean stage lowers.
A easy plan, however a gargantuan challenge. Consorzio Venezia Nuova, the physique set as much as handle the scheme, needed to construct one thing that might shield Venice from floods with out endangering its ecosystem or creating a big construction that may blight its magnificence. That meant, in contrast to the Thames Barrier or the Maeslantkering, the gates must stay underwater.

“MOSE is the one answer to this inconceivable downside,” argues Giovanni Cecconi, an engineer who labored on MOSE for 28 years.
The primary feasibility examine for cell dams as an answer to Venice’s floods was submitted in 1971, with laws passing on the proposal two years later. Politicians and engineers argued over and modified the challenge for 30 years earlier than building started in 2003. At the moment, its price was estimated to succeed in 1.6 billion euros over an eight-year building interval.
That forecast proved to be extravagantly optimistic. 9 years after the scheduled completion date, work on MOSE continues. In 2014 the up to date price was €5.5 billion, 343% over the unique funds. Now some estimate MOSE’s true constructing prices to be round eight billion euros. Following the profitable take a look at in October, the present estimate is for the gates to be recurrently operational in 2021. This cuts a piece out of MOSE’s deliberate lifespan.
“It was alleged to be completed in 2011,” says Jane da Mosto, an environmental scientist and co-founder of We Are Right here Venice, an NGO devoted to town’s preservation. She notes that Italy’s authorities designed MOSE to final for a century. “We have already misplaced 10 years of the so-called 100 years working time,” she sighs.
Tardiness is much from MOSE’s solely challenge. Whereas deployed, the gates would block ships from reaching and leaving ports, an important a part of town’s financial system. Extra importantly, they might lure sewage, which flows out from town into the Adriatic Sea, within the Venetian Lagoon.
Attributable to these unintended effects, MOSE is barely meant for “very intense excessive tides,” the official categorization of those who attain 110 centimeters. These trigger probably the most deleterious floods, however are uncommon sufficient, occurring solely a handful of occasions a yr, for MOSE to not severely hurt the lagoon’s ecosystem.
That is the loss of life of Venice.
Fabrizio Antonioli, geologist at ENEA
Or not less than, they have been uncommon sufficient. There’s one other downside the challenge’s designers did not anticipate: A woeful underestimation of sea stage rise means the gates might be deployed way more often than initially deliberate. The engineers accounted for a 20 centimeter rise over MOSE’s 100-year lifespan, in response to da Mosto. A 2019 report by the International Panel on Climate Change says a 60 centimeter rise is extra seemingly.
“MOSE have to be used not two or 3 times a yr [as officials thought]” says ENEA’s Antonioli, “however for instance 25, 30 occasions a yr.” Others estimate the gates will ultimately need to be deployed tons of of occasions a yr.
This is able to destroy town’s ecosystem. Sewage from Venice can be trapped contained in the lagoon for prolonged durations of time, inflicting heavy algae development. This algae would suck in all of the oxygen, killing every thing else.
“If you happen to go across the lagoon, there’s a vibrant fishing group, a clam business, a fishery, there are fish farms south of Venice,” Amos defined. “You are [hundreds of millions of euros] a yr in worth within the fisheries. … All of that’s more likely to be at risk.”
Consultants produce other gripes, too. Decrease areas like St. Mark’s Sq. can flood with tides as little as 80 centimeters, as an illustration, which means MOSE will largely go away it weak by design. This was the case on Oct. three, when MOSE’s deployment didn’t save St. Mark’s Square from inundation. Equally, components of Venice flood from beneath resulting from antiquated piping strategies, one other downside MOSE will not resolve.

Cecconi acknowledges the complication of a rising sea stage, however says this does not cut back MOSE’s necessity. He concedes that MOSE could not final for its 100 meant years, however says the system might be extra beneficial to Venice throughout its years of operation, since it will be wanted extra often than anticipated. He isn’t a stalwart defender of the challenge, however rejects those that suppose that MOSE is designed to repair all of Venice’s issues.
“If you’re oversimplistic and also you simply say ‘this ultimate answer goes to final perpetually or it should fail,’ oh sure, it should fail,” he says. “It has by no means been stated that that is the ultimate answer. That is insurance coverage to realize time for an additional answer. That is the which means of adaptation.”
Nonetheless, early exams of among the challenge’s gates reveal a extra deflating concern. MOSE could not be capable of function as meant with out exorbitant upkeep prices. A number of distorted hinges on the base of gates have been discovered throughout June 2019 trials close to Lido, one of many islands of the Venetian Lagoon. They’d largely been corroded by salt, according to La Nuova Venezia. Extra rusting and salt corrosion was discovered in May.
“If you happen to distort the hinges, then clearly they won’t rise correctly,” explains Amos. “Basically, they’re rendered ineffective.”
Consorzio Venezia Nuova didn’t reply to a number of requests for remark. Alessandro Soru, MOSE’s present challenge supervisor, last year told the Wall Street Journal: “It is a lengthy course of that takes tweaking, and primarily based on the exams we have now accomplished there may be completely no indication that MOSE will not work.”

Watergate scandal
With doubt mounting over MOSE, the consortium sought some vindication on July 10. In a ceremony attended by Giuseppe Conte, Italy’s prime minister, all 78 MOSE gates have been lifted in a public take a look at designed to display the system’s competence. Consorzio Venezia Nuova had beforehand examined sections of MOSE, however by no means earlier than had your entire set of gates been raised concurrently.
With the disclaimer that climate circumstances might be way more violent when MOSE is required — winds have been 4 occasions as robust throughout final November’s Acqua Alta — the demo went off with out a hitch. But even the prime minister was cautious about being too optimistic.
“We should all hope it really works,” Conte stated to reporters, after acknowledging the challenge’s historical past of “corruption and malfeasance.”
MOSE’s unhealthy fame is not only a matter of poor planning, however venality too. In 2014, MOSE grew to become the middle of an enormous corruption case. Consorzio Venezia Nuova is accused of funneling cash away from the challenge and utilizing it to bribe dozens of politicians and officers in alternate for supporting the more and more scrutinized challenge.
Venice’s mayor, Giorgio Orsoni, was accused of misusing funds embezzled from MOSE to finance celebration actions. In June 2014, he was positioned beneath home arrest and compelled to step down, however not earlier than blaming his Democratic Get together, saying it advised him to accept the funds and claiming different mayors earlier than him had accomplished so too. Giovanni Mazzacurati, head of the Consorzio till 2013, was charged with bribing politicians, reaching a plea deal before dying at 87 last year.

“The engineering and the development and the supplies used are very worrying,” explains da Mosto, “however even worse than all of that’s how the entire challenge has, and is being, managed.”
Cecconi blames lots of the challenge’s delays on “the bottleneck of forms.” After the corruption scandal in 2014, work on the challenge grew to become glacial. The Italian authorities tasked a fee with operating the consortium, a turnover which misplaced a yr of building. In 2018 the consortium’s commissioner said MOSE was 93% completed, up simply eight% from the reported completion rate in 2013.
“There is a massive foyer by Venetians in opposition to this entire challenge,” says Amos. “Not solely is it siphoning cash from different tasks round Italy, but it surely implies that there’s not sufficient cash left for doing the day-to-day enterprise inside Venice. At some phases, there wasn’t even sufficient cash for rubbish disposal.”
Critics cost that MOSE is extra about politics than downside fixing, a stigma predating its building. Cecconi notes that, even within the 90s, the challenge was a “political flag” for individuals who have been for or in opposition to it. This has poisoned dialogue.
“There are two events, they do not converse to one another. One that claims MOSE is massive enterprise, helpful solely to the people who invented it on the detriment of the residents. The opposite is the celebration of doing, [who say] MOSE would be the ultimate answer for town. Each of them are incorrect.”

Opposed by environmental teams, Italy’s influential nationwide inexperienced celebration and the Venice Metropolis Council (certainly one of a number of bureaus associated to the challenge), MOSE had been mired in political quagmire for practically twenty years — for the reason that Consorzio Venezia Nuova was tasked with safeguarding Venice in 1984 — earlier than the primary brick was laid in 2003. The gridlock was damaged by Silvio Berlusconi who, after changing into prime minister in 2001, enacted an infrastructure legislation that enabled him to sidestep the forms that slows down essential nationwide tasks.
Amos describes MOSE as a Berlusconi “vainness challenge” and says that the prime minister was conscious of the pink flags however insisted or not it’s constructed “come hell or excessive water.” The challenge has by no means been universally well-liked: As Berlusconi inaugurated building with a ceremony in 2003, environmentalists on small boats tried to disrupt the festivities. A hydrologist dropped at Venice to judge MOSE was asked in 2003 by CBS (CNET and CBS have the identical dad or mum firm, ViacomCBS) whether or not he thought the scheme would work. “I do not suppose so,” he answered. “I do not suppose you are going to march ahead, not an inch.”
Even after building started in 2003, there was a major push to shelve the challenge. In April 2005, after an anti-MOSE mayor got here into energy, Venice’s metropolis council ordered police to halt building, and environmentalists started protesting with renewed zest. However Berlusconi rejected the mayor’s request to pause the challenge. “The final doubts have vanished,” he said at the time. “MOSE might be made.”
Berlusconi’s workplace was reached for remark however didn’t reply.

Da Mosto says there’s greater than sufficient blame to go round. “All of the governments that got here after [Berlusconi’s] may have accomplished one thing to vary it,” she says. “You’ll be able to change these big infrastructure tasks, or cease them or reverse them when you get new data and understand it is the incorrect factor to be doing.”
The flooding downside will solely get extra pressing within the subsequent few a long time. Over 5,500 sq. kilometers of land, together with Venice, might be underwater by 2100 if local weather change is not halted, in response to a 2017 study led by ENEA’s Antonioli. (Cecconi disputes the methodology of the examine, which checked out deserted millstone quarries throughout the Mediterranean coast to establish sea stage rise over the past millennium and extrapolate anticipated sea stage rise over the following century.) Not like most different coastal cities, Venice’s woes will get international consideration. However there’s nonetheless a danger that it will take too lengthy for MOSE to be confirmed an empty answer.
“Till individuals get up to the truth that MOSE is not going to resolve Venice’s downside, different choices usually are not going to be taken severely,” says Amos. “However to actually be capable of display [that MOSE isn’t going to work] will take one other 20 or 30 years, by which era it’ll be too late for Venice.”
Regardless of looming issues, Oct. three’s profitable take a look at has introduced hope to Venice. “Right this moment is an historic day as a result of we must always have been stuffed with water by now and as an alternative we’re dry,” a local cafe owner said to Reuters. Residents took to Twitter to exclaim their aid, together with one who referred to as it “possibly the best ‘happy birthday’ message I could have received.” The town’s mayor, Luigi Brugnaro, proclaimed that Venice “stopped the ocean.”
“A lot of unhealthy issues have occurred right here, however now one thing fantastic has occurred,” he said to reporters on Oct. 3.
Now town braces for November and December, when acqua alta are most frequent and sometimes most fierce. Venice’s 2020 flood season has simply begun.
