Canale dei Petroli | Venice: I am not making this up

Motondoso, Venetian History, Venetian Problems

get to know the mud

March 14, 2025 11 Comments

In the canals, too much mud can be a problem, but one doesn’t see it until the extreme low tides of mid-winter. When anyone asks me how deep are the canals, I usually ask “You mean at high tide? Or low tide?” The height of the water changes, but over time so does the height of the mud.

You could call it the lagoon’s base layer. There are places where there’s too much mud, mainly in the canals; it accumulates and creates problems for boats when the tide is low and, equally important, problems for buildings whose drains it has blocked, and so we have to take it away.

But there is an equal and opposite problem of there not being enough mud in places around the lagoon, where dredging has been heavy or, more frequently, where the motondoso (waves from motorboats) has loosened the soil, and the tide and waves have washed it out to sea. Waves that demolish the wetland marshes (barene) or, on the other hand, fill up channels, have been known for years to be wrecking the lagoon’s wrinkly underwater shape, smoothing it out and slowly turning it into a sort of bay of the sea. Bays of the sea are an entirely different ecosystem from lagoons, but no matter! Motors are indispensable for keeping the city going, and the lagoon is just going to have to suck up (so to speak) the consequences.

At water-level you may notice only water, but the lagoon is full of mud.

The 17th-century Venetians knew the lagoon dynamics intimately. Their survival depended on it. Fears of the lagoon silting up from the several rivers that flowed into it led them to an epic undertaking: From 1600-1604 they cut the river Po to divert it southward into the Adriatic.

In 1993 it was decided to redistribute the quantities of mud in the city and lagoon: Simple, logical, effective, positive. Dredging proceeded and the mud was deposited in various locations where it was useful, or at least not problematic. In fact, moving mud around is far from a recent phenomenon — it’s been done many times over the centuries resulting in consolidations, expansions, and entire new islands. This assortment of maps showing the Morphological Evolution of the Lagoon of Venice from the XVI Century till today is very interesting. In the 20th century Tronchetto and Sacca Sessola, to name only two, rose from the lagoon bottom created with dredgings.

And so, in the fullness of time, the dredges were at work outside our door in 2021, and they were at it again just two months ago. All seemed to be going well, but suddenly we read that things have taken an unexpected turn. The mud is unusable!

The dredger the first day of work thought it was a good idea to tie his behemoth to one of our little pilings to resist the weight of the mud he’s pulling up. He was wrong. But you can appreciate something about the mud here: It’s tenacious. Once it grabs onto something, it really doesn’t intend to let go. This went on for hours, the modest pole yanked sideways, as you can see; it simply couldn’t be dislodged, although it’s now a bit shaky. The next day he moored the monster to the metal ring on the street, and we’re trying to help our piling begin to trust people again.

The headlines have been blunt: “Unusable muds, the lagoon in crisis, the dredging has been stopped in the lagoon.” “The new Protocollo of 2023 for the sediments dug in the canals doesn’t work anymore because the parameters of ecotoxicity are too rigid.” “First they were considered clean and good for reconstructing the barene. But no more: Now there’s a risk of blocking also the dredging of the most polluted.”

This problem has come up literally in mid-dredge. It’s a little awkward to discover that the Protocollo of 2023 is invalid when the barges are full of mud, so now what? Is there a Plan B? “Strictly speaking, we don’t have one,” to quote CIA operative Gust Avrokotos in the film “Charlie Wilson’s War.” “But we’re working on it.”

So what changed all of a sudden? It’s that, as the headline noted, the standards are suddenly stricter as to what mud is classified as “ecotoxic” (either biological or chemical) and therefore where it can be dumped. (Don’t write in, I know that everything is chemical, looking at the universe. We’re roughly distinguishing here between chromium and E. coli.)

Nobody’s surprised to hear that there are toxic substances in the lagoon — just look at the Industrial Zone shoreline and draw your own conclusions. A few years ago the University of Padova and Ca’ Foscari in Venice studied some mollusks taken from the channel bordering the mainland. Researchers found that the bivalves contained a quantity of poisonous substances 120 times higher than in the rest of the lagoon.

So here we are. Where will the mud go?

Men used to do this with shovels. Not underwater, of course.

All muds are not created equal. Category A, the cleanest kind, is safe to put under the water, so it can be used “nourish” the shrinking barene. Other muds, the more toxic Category B and C, can’t be put back into the lagoon, no matter how worthy the reasons, and have to be banished to the Tresse island. And God forbid all these muds should become mixed together. Burning the mud is an interesting proposal, but it’s hard to agree on where to put the ash.

Also, the Tresse at the moment is running out of space. There have already been discussions about enlarging it, but quantity and quality, as often happens, are in conflict. Decisions lag. Bureaucratic, legal, logistical issues keep bumping into each other. Cost must be in there too, somewhere. The Morphological Plan of the lagoon was shot down in 2022 and nothing has been heard of it since.

The Isola delle Tresse began in the 1930’s as Storage Tanks island, and was expanded in 1993 with a million cubic meters of mud and other material dredged for the benefit of the Port of Venice. This raised the island by nine meters (30 feet) and doubled it in size. Now it has been proposed to deposit as much as an additional four million cubic meters of mud, which would raise the island as high as 13 meters (43 feet). May I take just a moment to recall that when UNESCO designated Venice as a World Heritage Site in 1987 it also included the lagoon? Toxic mud doesn’t sound very World Heritage Sitey.

So, back to the dredging at hand: After weeks of hardy gouging and hauling, the mud’s permission to land, so to speak, has been revoked. The Department of You Should Have Seen This Coming isn’t answering its phone.

The barene (semi-solid mud) are beautiful and crucial to the whole ecosystem. But *motondoso*, or waves caused by the anarchy of motorboats, slices away at their soft soil. This goes on all year long, but especially in the summer. Note the distance between the wooden piling and the islet. They used to be much closer together. Shrinking barene aren’t good for the health of the lagoon as a whole.

Of course the plant roots help stabilize the soil, but they only go down so far. Soon the upper layer will collapse and slide into the water, filling up the channel. We need the barene and we also need the channels, but they do not play well together. Eventually there will be too much mud in the channel, and not enough island, and dredging will be called for. And perhaps expansion afterward. Not literally inconceivable.

To resist the waves gnawing at the barene, various defenses have been tried. Above is somebody’s idea of a breakwater. The barena is clearly not reacting as the planners intended. You can see here why it was hoped that the latest batches of dredged mud could enlarge shrinking bits of land, because more and/or larger barene would be a great thing for the ecosystem. Even if you don’t care about the ecosystem — I don’t judge — more barene would serve as barriers to slow the incoming tide, the way they always did before motondoso began to tear them apart.

This construction is not destined to last long; the team behind this project seems not to have observed what happens to wooden pilings in the water.

The lagoon loses 600,000 cubic meters of sediments every year, leaving an increasing wasteland behind. You can easily see the difference between the lagoon north of Malamocco (divided by the Canale dei Petroli, about which more below), and the southern lagoon. If too much mud in one place is a problem, too little mud in another isn’t any better. Fewer barene and fewer channels mean the water can rampage around and carry even more mud away with the tide, or deposit it unhelpfully elsewhere.

1901. We see lots of squiggly channels back then (which, like the barene, slowed down the tide, and the dislodging of sediments). You also see that the shoreline was squishier and more ragged, providing more space for the water to come and go, moving more slowly in the process. But too many channels were doomed, like the little one circled in red above.

1932. Look at the little channel (*ghebo*, in Venetian) circled in red again. You see that natural processes have caused it to begin to fill in, but it was still in good shape at least ten years later because Lino remembers it well. His father would take him out fishing in their little boat and they rowed along this canal on their way to the best spot to “dig” for canestrelli, or little lagoon scallops (*Aequipecten opercularis*). Note: The different colors indicate varying depths of the water. You’ll see that change over the decades too.

In the Thirties the Industrial Zone was being built; for Venice’s post-war economy it seemed like the greatest plan ever, and in many ways it was. In their great days (now past), the chemical refineries here were the largest in Italy. Oil and chemical industries require raw materials, and those require ships, and ships require reliable channels for passage. That broad, curving channel marked in yellow on the map above that enters the lagoon from Malamocco does not look like anything a big ship would want to navigate, and of course ships also need a waterway to reach the mainland port area. And so the Canale dei Petroli (“petroleum canal,” in honor of the expected tankers) was planned.

1970. The triumph of the shipping. The broad, curvy yellow channel (which also slowed the force of the tide) was bypassed in 1964-1968 by the digging of the channel that is straight as an airport runway: The Canale dei Petroli. The resulting tons of mud went to the shoreline, reshaping it by the formation of three longish islands (generically called *casse di* *colmata*) that were created along the flank of the mainland. They were intended as the land for the Third Industrial Zone, which was never built. Left to their own devices, they’ve become a sort of oasis, especially for birds.

Dredging the Canale dei Petroli created a channel 18 meters (60 feet) deep, 15 km (9 miles) long and 200 meters (656 feet) wide. If you had wanted to suck the sediments out of the lagoon, you could hardly have done better. But the wakes of the cargo ships also stir up the sediments and they don’t all reach the sea. Result: More dredging is needed periodically as the channel proceeds to silt up. Further result: The tide entered faster and with more force than ever before, and before you could say “Worst flood in Venice’s history, November 4, 1966” the city went under. Venetians weren’t slow to see a connection between the canal and the flood, but what was done was done.

And this is more or less the situation today.

Moving mud means moving water. These maps were made in 2009, so the situation may well have changed yet again since then. Looking at you, effects of MOSE. (On the right panel: This map was assembled for study use of the Committee of Public Health of Venice, from the pages published on the site https://www.istitutoveneto.it/flex/cm/pages/ServeBLOB.php/L/IT/IDPagina/1. Credit and rights to this work belong to Diego Tiozzo Netti. The indications of the tidal flows are by Umberto Sartori.)

We’re looking at tide patterns, otherwise known as the hydrostatic equilibrium of the tides in the lagoon over many centuries.

LEFT PANEL: The solid red lines show the tidal pathway from the inlet at San Nicolo’. The solid green is the water entering from Malamocco (Alberoni). The thin blue line across the center of the lagoon emphasizes what we can see where the arrows meet, the point where the two incoming tides form the spartiacque, or “division of the waters.” The dotted red lines show tidal flow before the landfills created by the Austro-Hungarians (who left in 1866) and Fascists (1922-1943). The dotted green lines show the tide before the landfills made by the post-war “democratic-clientele governments.” The dotted dark-blue lines are the principal zones of sediment deposits, which makes sense considering the movement of the tides.

RIGHT PANEL: The pattern of the rising tide in 2009. The solid red line shows the pattern of the tide entering the lagoon from the inlet at San Nicolo’. The solid green line shows the tide entering from Malamocco (and, obviously, along the track of the Canale dei Petroli.) This graphic shows the effect of losing the mudbanks, natural channels and barene, smoothing out the lagoon bottom that used to be naturally uneven and knobbly.

I think the tides and the mud matter more to many other creatures than they do to mere humans. This barena that was built next to the Certosa island is a haven for flamingoes, Eurasian oystercatchers, egrets, herons, common shelducks, and the now-ubiquitous sacred ibis. And undoubtedly more that I haven’t discovered yet.

The ibis (*Threskiornis aethiopicus*) love the mud.

Snowy egrets (*Egretta thula*) don’t particularly care about mud, per se, but they like the easy fishing when the water is shallow.

Curlews (*Numenius americanis*) absolutely love the mud, digging up worms and other little submerged treats.

The plover (*Pluvialis squatarola*) is another huge fan of mud.

The oystercatcher (*Haematopus ostralegus*) is really beautiful, unless you’re an oyster, obviously. They also wade around looking for mussels and earthworms.

The grey heron (Ardea cinerea) is the apex wader. Evidently he’ll eat almost anything.

Here the lagoon bottom is fairly firm when it’s exposed at low tide, but if you walk into the water you will sink into squishy mud up to your ankles. Pause to admire the tracks of the birds who have traversed this territory, snacking to their heart’s content.

The important thing is that the lagoon bottom isn’t perfectly flat.

This is evidently the perfect place for a feast. The shore is littered with clam and oyster shells, the casings of creatures that need the mud to live.

The mud doesn’t just feed the birds. There are indeed oysters in the lagoon and they are delectable. Lino spent one Christmas Eve afternoon out in the lagoon and brought home a batch of these for our dinner. These three clutched together, though, seem to have formed a sort of Wagnerian pact or something.

We sometimes find scallops, even though they’re not as plentiful as when Lino was a boy and would go home with a bucketful.

That was a good day out — lots of different types of clams (and this isn’t all of them, by any means). They may be pondering how unmuddy the world has suddenly become.

Regard the mud. The waves from some passing boats clearly show that the mudbank is just below the surface.

You see water, I see mud. The surface is smoother where the water is shallower as the tide rises or falls. If you’re out rowing and you see this, you have only yourself to blame if you run aground. You were warned.

If you want a lagoon, you have to want mud. Otherwise you might just as well look at your bathtub.

Problems, Venetian Problems

Meanwhile, in other news….

July 17, 2021 3 Comments

Now that the G20 has come and gone, the surface of life that was so agitated thereby has returned to its normal level of agitation. There are plenty of things to keep track of, to one degree or another. In some cases, to many degrees.

Here are a few of them:

REDENTORE: The annual feast of the Most Holy Redeemer is tonight and Sunday — the big waterborne festivities on Saturday, the races and big religious celebration on Sunday. Last year there were no fireworks, which left a huge hole in the festivities. This year there will be fireworks, but in a serious effort to prevent the hazardous clumping-together of crowds the city has imposed a limit of 18,000 people, total, and those persons have to have made a reservation. To reach the place or area they’ve booked, they have to show their printed ticket as well as their “Green Pass,” or other certificate of vaccination, OR a document that confirms that their swab was negative within the 48 preceding hours.

The obverse side shows my name, birth date, and a few other details not interesting to anyone but them and me. This document allows me to travel to other European countries without having to quarantine.

Barriers are being set up around the reservation-only zones. Here, this fence ought to keep the traffic lanes separated. If Carnival is any example, it won’t.

These barriers are intended to prevent people falling in the water, I suppose; maybe they should prevent people in boats trying to board somebody or put them ashore?

The rules are the ones that we all know so well by now: Masks and distancing. Tickets have been organized in sub-sectors. Redentore used to be a real let-it-all-fly sort of festa; a party now where everyone will have to behave like Captain Von Trapp’s children is going to be really different.

Boats obviously won’t be permitted to tie up to each other: social distancing afloat. No trying to pass from boat to boat. No dancing parties aboard (take that, you big floating discotheques). The watery areas are delimited according to size and the use of boat, and you have to show a printed “ticket” from your booking (on water as on land) to be permitted to enter the area. Once your boat has entered its appointed area, it is forbidden to exit, nor will it be permitted to put people ashore. Boat captains have to keep a complete list of passengers for 14 days. Also, wear your mask.

There are regulations for people booking space along the fondamentas to watch the fireworks, or to scarf their dinner, but I’m not going to go into all that. If you’ve booked a space, you already have the rules. If you haven’t booked, you’d better hop to. Preference is being given to Venetians, it says here.

Lino and I will not be there; it’s been years since we decided we couldn’t stand the mayhem of the motorboats in the dark, with their drunk drivers. We might walk up to the fondamenta dei Sette Martiri (where I didn’t see any signs of assigned places) if it’s not too crazy.

The little yellow slice, Area 5 Dogana, is the space allotted to traditional boats, either rowed or with a motor of maximum 9.9 hp. The other zones are organized for boats according to size and use (pleasure, work, etc.). No need to get into all the details. Note the white emergency exits. When Lino was a boy, the Giudecca Canal was so thickly covered with boats — all propelled by oars, of course — you could walk across them from one bank to another. And they were all massed in the Giudecca Canal to the west of the votive bridge, up toward the Molino Stucky. The Bacino of San Marco was just background decoration.

THE BIG SHIPS: Ship-haters rejoice: As of August 1, the biggest ships will no longer be permitted to pass through the city. These ships are defined as having at least one of the following characteristics: Gross tonnage above 25,000 tons; hull at the waterline longer than 180 meters; height of ship more than 35 meters, excluding ships that are motor- and sail-driven; use of fuel in maneuvering that has a percentage of sulfur equal or superior to 0.1 per cent. Like any other cargo vessel, the big cruise ships will be routed from Malamocco to Porto Marghera, one of many solutions that have been discussed since dinosaurs roamed the earth. But this is just a stopgap. The real solution is the offshore port, and that’s not happening tomorrow.

Seeing that neither Porto Marghera nor anywhere else will be ready this year, the MSC Orchestra or Magnifica and Costa Deliziosa (the only big ships on the dance card this summer) will be departing, respectively, from Monfalcone and Trieste, up along the northern Adriatic coast. Passengers arriving in Venice will be swabbed or otherwise health-checked at the Venice Maritime area, then loaded on buses and driven a few hours to their ships. So much for the thrill of cruising from Venice.

The offshore port project is going to take some time. Phase One, send in your proposals by December 31, 2021. Make sure your design can accommodate modern container ships as well as the biggest cruise ships, and make sure the port will be safe in stormy seas because there won’t be any lagoon to protect you anymore. Phase Two, five experts evaluate the proposals. Phase Three, choose the winner. That decision will be made by June 30, 2023, if all goes as planned. That’s a pretty big “if,” I feel compelled to add.

Seeing that creating the offshore port will take at least five to six years, Porto Marghera will have to be modified fairly quickly. Building the new passenger terminal there, deepening the channels and revising the current industrial docks will cost 157 million euros — a hefty sum for a temporary set-up. Then again, “temporary” has a flexible meaning here. The Accademia Bridge was built in 37 days in 1933 as a temporary structure while proposals for the real bridge were to be evaluated, and it’s still there.

I have the impression that the sudden decision on dealing with the big ships is linked somehow to the fact that UNESCO recently decided to designate the water entrance to Venice — Bacino of San Marco, Canale of San Marco and the Giudecca Canal a national monument. This is surprising in that UNESCO, when it listed Venice as a World Heritage Site in 1987, specifically included the lagoon. You wouldn’t know that by the savaging of the environment that has gone on since then, but anyway, I’d have considered the Bacino, etc. as part of the lagoon. Now it’s a national monument. Okay then.

Spare a thought, though, for the humans — 1,260 direct workers and 4,000 indirect workers — involved in what will be a radical restructuring of the whole shipping enterprise here. Many are fearing for their jobs.

Almost no workers believed that this decree would come so fast, and right in the middle of the season. The maritime agencies are also worried. Every shipping company is required by law to engage a maritime agency, but, says Michele Gallo, head of two agencies, “You can’t even think of having the same ships as before coming to the docks at Porto Marghera, using the same places as the commercial ships. This is a devastating decree.” Organizing the entry, passage and departure of so many ships through the inlet at Malamocco and along the Petroleum Canal (Canale dei Petroli) is going to be a job worthy of an air traffic controller.

By the way, all this increased traffic will make it even more important to keep the aforementioned channel dredged. However, the deeper the channel, the faster the tide enters and exits, and already this action removes millions of cubic meters of sediment from the lagoon every year. Everyone knows that the Canale dei Petroli has thus caused incalculable damage to the lagoon and its extraordinary ecosystems. Ironic that UNESCO decided to designate part of the lagoon as a national monument with the notion of protecting it, but they seem not to have taken into account the effect so much extra traffic will have in a channel that essentially behaves as if it were a water vacuum sucking the soil from the lagoon.

This was the lagoon’s circulatory system in 1901. Lots of arteries and veins and capillaries kept the lagoon biome thriving.

In 1932. Notice the large natural channel at the bottom of the picture — the inlet at Malamocco. Here it is the shape of an oxbow. Works fine for the lagoon, but wasn’t at all suitable for commercial traffic.

The oxbow was furloughed when the Canale dei Petroli was dug in 1964-68. The channel shoots straight from the inlet on the right to the shoreline, and was dug along the shoreline in order to allow the tankers and other big merchant ships to reach Porto Marghera in the upper left-hand corner. After only two years, the effect was evident. Today, in view of the cruise ships arriving, dredging the channel has already begun, and will continue for 12 months. A deeper channel means the tide will be faster than before. All the little canals that used to be there helped to slow the tide down, but as you see, the tide won.

On the left you can see the tide patterns before the Austrian domination (1814), while on the right the tide patterns in 2009. So by all means make all the big ships traverse the lagoon from Malamocco for however many years it will take for the offshore port to be built. I’d just avoid presenting myself as a defender of the lagoon at the same time.

FREE MARCO ZENNARO:

Marco Zennaro (veneziatoday.it)

The 46-year-old Venetian businessman, well-known and loved by many, has been in prison in Sudan for three months. He is the owner of a company that produces electric transformers that has been doing business in Sudan for years. He has been accused by a Sudanese company of fraud, but the situation is an utter tangle of claims and characters. However, the photograph of the cell in which he was kept for two months with 30 other men, at temperatures of 114 degrees F., was all too comprehensible. Yes, the Italian government has attempted to intervene; yes, money has been paid, but turns out someone wants still more.

Now he is on house arrest in a Sudanese hotel, awaiting the next hearing (August 9) in the string of court appearances that may finally resolve the problem. He has already been absolved of two accusations, but it’s hard to know who wants what at this point. Of course money is at the core of this. Marco is well-known in the Venetian world of sport — Venetian rowing, for one thing, as well as rugby. As it happens, Lino has known him since he (Marco) was a boy. Also, Lino taught his mother how to row.

This one is written in English, no less.

“We Support Marco.” Petitions and initiatives continue. On June 13, some 15 Venetian rowers conducted a 24-hour event in which they took turns rowing from the Rialto to the Salute and back a la valesana (one person with two oars). They continued from noon June 13 to noon June 14 to raise awareness of this situation and urge its resolution. But here we still are.

“Let’s get Marco back.” This banner has been posted around much of Italy by now, by a far-right “association of social promotion” called CasaPound. (lagazzettatorinese.it)

MOSE:

Are we heading back to this again? Oh boy.

Mose worked last winter (except for one time), so you might think all is well? You would think wrong. I’m starting to dread the winter again.

The plan was to complete all the work by June 30, and declare the project finished on December 31, 2021. But that timetable is now in tatters for various reasons, primarily money problems (as always). The refusal of some suppliers to continue without payment also slowed things down, and the work was officially suspended yesterday, July 16, even though it actually had been stopped for three months already.

Without regular tests, without personnel from the companies involved, without some degree of ongoing maintenance, it’s not certain the gates will even rise when needed. Broken elements haven’t been replaced, parts are deteriorating because there is still no air conditioning in the underground gallery. There is severe corrosion that has been reported for years, to the frames of the underwater tensioners as well as the hinges of the gates. Encrustation of barnacles and other crud will certainly make the gates heavier. The gates at San Nicolo’ have been underwater for eight years now.

Bids have been solicited for a maintenance program budgeted at 64 million euros, even though some estimates maintain that at least 100 million euros will be needed for this every year. (Personal note: Lino has never batted an eye at the titanic construction costs. His refrain has always been simply “And the cost of the maintenance?”)

A Venetian deputy in Parliament, Orietta Vanin, has written to Enrico Giovannini, the Minister of Public Works, saying “A plan is missing for the launch of the work and the completion of the machinery. When is Mose going to be tested? What is the risk to the city in view of autumn? At what point are the interventions for the security of the Piazza San Marco? We’ve asked several times but have never had a response.”

TOURISM:

Not exactly a horde at 9:00 AM on a Saturday morning. I did see a group of about 15 people being guided around the Rialto Market.

The infamous hordes are not yet swarming the streets; tourists there are, many of them still day-trippers, but not insupportable numbers, by any means. We could probably use a good horde or two right now. Happily for everyone, American travelers are finally permitted to fly to Venice (I presume also to the rest of Italy). Delta Airlines has non-stop flights from Atlanta and New York, and the other day 200 passengers from the USA disembarked to great, if silent, applause. That’s just a drop, however, as the Venice airport is currently handling 15,000 “passages” a day, a mere third of their daily pre-pandemic total.

Still, no coherent plans for managing the eventual masses have yet been proposed. The secretary of the artisans’ association, Gianni De Cecchi, says “The pandemic has passed in vain.” So stand by for the usual complaints, protests, and laments to come forth again. Probably toward the end of next summer, if forecasts can be trusted. Stay tuned.

I like these tourists. Too bad there aren’t enough of them to keep Venice afloat.

I hang the sheets out to dry, he raises his sail. The life, she goes on.

Petition to halt the Canale Contorta “Solution”

August 27, 2014 No Comments

This is one view of what a lagoon looks like, especially when the tide is going out and the clams are just waking up.

This is an unusual step for me, but I think it’s worth it. Even though I don’t place much trust in the power of petitions, maybe this time it will be different.

In any case, I’d like to inform you of one which has gone from 700 to 20,000 signatures and counting in about ten days. I think that means something.

“Gruppo 25 aprile” is a new group of Venetians and Venice-lovers which is concentrating its efforts on stopping the digging of the “Canale Contorta.” Its reasons are shared by many scientific and environmental experts, not to mention a huge percentage of everyday Venetians.

Once the subject of the big cruise ships and their potential to damage Venice became one of the hottest debates and power struggles of the year, the need for finding an alternate route from the Adriatic to Venice obviously became paramount. My own opinion is that any “cure” they find will be worse than the “disease” (i.e., the ships in the Bacino of San Marco) — or, as the Venetians put it, el tacon xe pezo del buso (the patch is worse than the hole).

Many solutions have been proposed, but only one had the political muscle behind it to get itself officially considered by the “Comitatone” (“Big Committee”) in Rome, which had the power to decide yes or no. That “solution” is the dredging of the Canale Contorta.

Sorry it's in Italian. The red line shows the current route by which cruise ships enter and leave Venice. (www.corriere.it). — Sorry it’s in Italian. The red line shows the current route by which cruise ships enter and leave Venice. The solid yellow line is the Petroleum Canal. The dotted yellow line is the Canale Contorta, which already exists in a simple, primitive, shallow way. Changing that will change a whole lot besides. (www.corriere.it).

Thanks to a calculated maneuver by its promoters, the meeting at which the decision was to be made was held in August. (“August” is Italian for “vacation.”)

As Marco Gasparinetti, the coordinator of Gruppo 25 aprile, explains (translated by me from the Gazzettino):

“The decision of the Comitatone on August 8 was a summer blitz with which they hoped to surprise a city on vacation. But the city is fed up with being expropriated from the decisions which concern it, and this time is going to make its voice heard.”

The political vacuum in Venice since the government fell on June 4 has at least one positive aspect, and that is that finally there seems to be some possibility that the voices of Venetians might be heard somewhere beyond their living rooms and favorite bars. Yes, there is chaos in almost every aspect of daily life here now, but the fact that essentially only one man is in charge — Vittorio Zappalorto, the Commissario who is temporary governor — means that the city is less strangled by the political and bureaucratic tentacles of the past 20 years. It’s as if — to try another metaphor — a colossal dose of drain cleaner has ripped through the city’s emotional and civic pipes.

Back to the Canale Contorta. It may not be too late to stop it. Therefore Gruppo 25 aprile has created a petition addressed to Prime Minister Matteo Renzi, as well as all the ministers concerned (Environment, Infrastructure and Transport, Culture, etc.) urging them to withdraw the hasty approval of what it (and I) regard as a catastrophic move, the last nail in the coffin of the lagoon after the drastic effects of the MOSE floodgates, not to mention the Canale dei Petroli (“Petroleum Canal”), dug in 1969.

A drawing from the 1980's shows the network of canals, or "ghebi," in the lagoon. In 2002, a NASA satelite shows the same area, pretty much leveled and smoothed out by the terrific suction of the Petroleum Canal over the years. — A drawing from the 1980’s shows the network of canals, or “ghebi,” in the lagoon. In 2002, a NASA satelite shows the same area, pretty much leveled and smoothed out by the terrific suction of the Petroleum Canal over the years. (Umberto Sartory, 6/29/2006, venicexplorer.net).

The page connected to the link above shows a map (left) from the 1980’s which outlines the major and some minor natural channels (ghebi) which used to cross and re-cross the lagoon. It represents a complex biological realm which the effects caused by the Canale dei Petroli, in 40 years, has done much to destroy, as shown by the NASA satellite image made in 2002 (right). Do you see ghebi? I see just a broad, anonymous stretch of bottom. That’s what the fish see, too.

Lagoons are rich, meaty environments. The sea is also nice, but not like this. I believe the difference is easy to see.

Here is a section of a brief but pointed piece by Tom Spencer, reader in coastal ecology and geomorphology at the University of Cambridge, and director of the Cambridge Coastal Research Unit:

Coastal lagoons are transitional environments between fully terrestrial and fully marine conditions; in the absence of direct human intervention, their long-term tendency is to infill with sediments. Over the centuries, the Venetian Republic was instrumental in maintaining this vital yet delicate land/sea balance, starting with the huge undertaking to divert the main rivers in the 16th century and stop the region from silting up altogether.

Since that time, however, historical and near contemporary records of changing patterns of lagoonal topography and water depth; tidal currents; and sediment transport from the lagoon to the sea all show unequivocally that the current lagoon is moving in the opposite direction, becoming a downward-eroding, sediment-exporting system. It is thus on a trajectory that will turn it into a fully marine bay. That this process is well underway is evidenced by the appearance of plant and animal species in the lagoon that are characteristic of marine environments.

We may argue about the velocity of this trajectory but the evidence for such a trend, clearly related to a whole series of human interventions from the late 18th century to the present, is not in doubt. As wave height and tidal flows are strongly influenced by water depth, such a shift has critical importance for the sustainability of the historic core of Venice itself. If we drill down into the detail behind this general trend, it is clear that the excavation of two large canals (Canale Vittorio Emanuele, around 1925, and Canale Malamocco Marghera, around 1969) produced strong transversal currents across the original tidal network, with consequent siltation of channels and erosion of adjacent shallows.

There is one simple question that needs to be answered. Can we be assured that the large-scale excavation of the Canale Contorta will not have the same effect and not give the Venice lagoon a further shove in the direction of yet more environmental degradation and urban vulnerability?

The petition asks the national government to reconsider all the proposals. That seems like an extremely modest request.

The petition can be signed online. Here is the link explaining their position, with the possibility of signing. (“Firma” means “signature.”)

Or, you can copy and paste:

If anyone might be tempted to suppose that Venice can be happy and healthy in the middle of a maimed and deformed lagoon, that person should consider this: That the water through the Canale Contorta will enter or leave the lagoon with a force and a quantity that will endanger the city to a degree that the biggest cruise ship could never dream of.

The lagoon is loaded with egrets, who might like to be considered in the great scheme of things. — The lagoon is loaded with egrets who might like to be considered in the great scheme of things.

Venetian Problems

Taking a closer look at New Year’s Eve

January 5, 2014 2 Comments

The Piazza is big, but it's not THAT big. I still don't grasp how 80,000 people got in there. Or got out. — The Piazza is big, but it’s not THAT big. I still don’t grasp how 80,000 people got in there. Or got out.

Probably nobody is thinking about New Year’s Eve anymore, no matter where they spent it. But here in Venice it’s not over yet, as the papers continue to publish a cascade of ever-more-detailed articles, personal stories, and editorials on how things went.

In a word: Badly.

So I’m going to back up from my earlier post and try this report again. Because in case you don’t know, the three most beautiful words in the English language are not “I love you” (though they’re not the worst, either).

Nope. The three MOST beautiful words are “You were right.” And in my case, its close cousin: “I was wrong.”

I admit that I felt uneasy writing that sunny little post about New Year’s Eve. Even as I wrote it, I had the strange feeling that I was unaccountably speaking in some unknown language from the planet where life is beautiful all the time.

I must have inadvertently disconnected my internal smoke-detector, because the news is demonstrating, in ever more lurid detail, why I will never go near the Piazza San Marco on the night of Saint Sylvester. And how inexplicably incapable the city is of organizing big events in some reasonable manner. And when I refer to the organization of big events, I have some small experience elsewhere; for example, the Fiesta of San Fermin at Pamplona, which I have attended twice. And I’d go back again, no matter how much I hate crowds, and one of many reasons is because it is organized and maintained in the most dazzlingly intelligent and diligent manner for nine solid days and nights. And a mere twelve hours drives Venice to its knees.

From 9:30 PM, rivers of young people arriving by train filled the streets heading toward the Piazza, smashing bottles and setting off firecrackers as they went.

Far from being a scene of frolic and light-hearted conviviality, as the night dragged on the Piazza San Marco (and Piazzale Roma, whence thousands tried eventually to depart the most beautiful city in the world) resembled a war zone, or a frat party of intercontinental dimensions. Words such as “assault,” “devastation,” and “outrage” highlight the reports of the night, and the morning after.

Piles of shattered glass bottles and pools of biological fluids from either or both ends of homo stupidus prostratus were only some of the abundant remains. There were also the bodies of comatose sleeping revelers scattered around the streets, lying where they fell when the fumes ran out.

People are fascinated by the damage water can do to the Piazza, but somehow the maxi-posters and the maxi-mobs have slowly come to seem normal. The water is normal, too, and has been normal for longer than there's been a city here. — People are obsessed by the damage that water can do to the Piazza, but somehow the maxi-posters and the maxi-mobs have come to seem normal. So millions have been spent to control the water, but virtually nothing to resolve what in fact should be much easier to deal with. I don’t get it.

The story in figures:

80,000 partyers, 10,000 more than the past two years. Most of the yobbos weren’t Venetian, but from everywhere else — what in New York are called “bridge and tunnel” people. I’ve seen them there at the St. Patrick’s Day parade, and it’s not lovely. It’s no lovelier here.

50 interventions by the 45 emergency medical personnel from the Green Cross, Civil Protection, and SUEM, the ambulance entity; most crises related to alcohol drunk, alcohol spilled (rendering the already wet pavement dangerously slippery), cuts by the broken glass of bottles blindly hurled into the air, blows to the head, and panic attacks caused by the mob and the explosions of firecrackers at close quarters.

100,000 euros ($135,868) the estimated cost to the city, excluding fireworks. This approximate number comprises: 60,000 euros for the collection and removal of 135 cubic meters (4,732 cubic feet)of garbage, of which 20 cubic meters (706 cubic feet) were of glass; 15,000 euros for the 60 Municipal Police agents on security duty. And the cost, not yet quantified, of the extra transport personnel (50 bus drivers and an unspecified number of vaporetto pilots). And the fuel required by the 20 garbage barges.

60 extra buses coming into Venice from the mainland; 123 extra buses between midnight and 7:00 AM from Venice to the mainland. Does this sound like a lot? Au contraire; the ACTV, in its wisdom, put on extra vaporettos, which worked well, but reduced the basic number of bus runs on a holiday eve. Because it’s, you know, a holiday, and the drivers want to be at home. New Year’s Eve in Venice, with reduced bus service. Explain this to the masses of tired, cold, exasperated people who were trying to get back home, who even overwhelmed the relatively few taxis in Piazzale Roma. Explain it to anybody, if you can. And I still can’t figure out how 50 extra bus drivers were sent to work if there were fewer buses. Or were they put to work scrolling the “Out of service” sign onto the buses’ forefronts?

The story in voices:

“It was hard, if not impossible, to move. Funky air, a mix of piss and drugs, the pavement “mined” with bottles, cans, and every sort of garbage…The Piazza was a disaster. Electronic music at full volume incited the crowd that was already drunk and out of control. A great number of young people had taken over, armed with every type of alcohol…the center of the Piazza was an inferno. Not just fireworks, but young people, Italian and foreign, were competing in a new entertainment: the launching of bottles…I didn’t see any security agents that would have forbidden this behavior…The day after, the marks remained on our city, heritage of humanity, devastated by barbarism.” (Margherita Gasco)

“According to a recent international survey, the night between the last and first of the year shows Venice to be among the principal capitals of the festivities on the planet. This shouldn’t prevent us from … reflecting critically on how these events are carried out — if they’re worth the trouble, if they still have their original sense.” (Gianfranco Bettin, the assessore for the Environment).

“Such a high number of people wasn’t predicted, nor predictable,” said Angela Vettese, the assessore of Culture and Tourism Development. (It wasn’t predictable? Does she not read tourism surveys?). “In the future, more prudence is necessary to protect the Piazza, and to invest in more surveillance, so that the police can check, count, and keep access to the Piazza within a determined limit. Furthermore, it’s necessary to organize only high-quality events, with spectacles that involve the public (more involved than they already were?), maintaining greater tranquillity.” She’s still new on the job, or she wouldn’t be talking like that; all these things have been said before, and before, and even before that.

Social network comments were divided between those who think New Year’s Eve in the Piazza is the greatest thing ever, and those who think the care and protection of the already fragile city is more important; those who insist it was just a normal night of festivity, and those who characterize is as another example of sheer lunacy.

“I urge the church to make itself heard, seeing that the civil authorities don’t feel any special need to safeguard the Piazza San Marco…Can we imagine an event like last Tuesday in the Piazza San Pietro in Rome?” (Franco Miracco, art historian).

“San Marco can’t be the only stage for events” (Mons. Antonio Meneguolo, diocese of Venice). “It’s not the number of people which creates bad behavior,” he said. “We can increase the security but it would be better to organize other activities elsewhere, and remove the emphasis of the publicity for “New Year’s in the Piazza,” seeing how the event ends up.”

“Venice continues to be seen as a city to exploit touristically down to the bone,” said Lidia Fersuoch, president of Italia Nostra. “More than limit access to the Piazza, it’s necessary to limited access to the city itself, because it’s impossible to contain more than a certain number of visitors.”

“Certainly, if we take as the limit the Pink Floyd concert of 1989, anything even just barely below that is considered tolerable…But hurling bottles, explosion of firecrackers, people who urinate and vomit in the streets, are these part of the normal course of public socializing? For some people, yes, but for us, no. Especially if it happens in the Piazza San Marco, which isn’t just any piazza, but a monumental area, as it was defined when concerts were stopped (because they have an excessive impact on the Piazza itself)… But why no to concerts, and yes to New Year’s Eve? We speak of “outrage” precisely because it’s a monumental area; you can’t remain indifferent seeing people climbing up the 16th-century columns of the Loggetta of Sansovino at the feet of the campanile. The piazza has always been the place for socializing, for events. But what events?” (Davide Scalzotto)

I think the Piazza looks wonderful like this. It's not that I'm anti-social, but on days like this it looks peaceful, and clean, and safe. I don't mean I feel safe, I mean it looks safe from us. — I think the Piazza looks wonderful like this. It’s not that I’m anti-social, but on days like this it looks peaceful, and clean, and safe. I don’t mean I feel safe, I mean it looks safe from us.

Here is what I ask myself and anyone who might be listening: There is a Superintendency of architecture, of art, of treasures. There is the Polizia di Stato, the carabinieri, the municipal police, the Guardia di Finanza. There are ordinances forbidding almost every dangerous and tumultuous form of behavior and the hazardous objects associated with them. Why is there no evident point at which any of these elements meet? The behavior and objects are at Point A, and any uniformed persons authorized to intervene are at Points Q, X, and Z. All told, there may have been more garbage collectors than anybody else at work in the Piazza, which seems backwards, to me.

In theory, if there were more agents of public order on duty, there would be less need for the First Aid stations, not to mention the ambulances and garbagemen.

But let me move on to a much more distressing thought.

Venice is a UNESCO World Heritage Site, which, unlike many of the 981 sites on their list, is a real place where real people live and move and have their being. This presents special problems which nobody seems able to anticipate, or resolve. I am at a loss to say why, except that with ten fingers per city councilor, there’s plenty for pointing at other people.

There are 49 UNESCO sites in Italy, more than any other country on earth. So far, none is marked as being “in danger.” I think Venice should be. I cannot conceive of shenanigans such as New Year’s Eve in the Piazza San Marco being tolerated in Angkor, or Machu Picchu, or the Alhambra, or the Red Fort Complex, or the Etruscan Necropolises, or the Potala Palace, or the Galapagos Islands. And this is not the first time. And yet, it goes on.

And I’ll say one more thing, as long as I’m on the subject: Of all the “properties” on UNESCO’s list of World Heritage Sites, only two, so far, have been de-listed. The reasons are given on this page of their website.

Between the catastrophes visited upon Venice under the ever-fresh rubber stamp of the Superintendency of Architectural Treasures (the tormented issue of the maxi-posters in the San Marco area has only been moderately resolved, among other things), and the continued abuse of the lagoon, which is also part of the World Heritage designation (from the Canale dei Petroli to MoSE and now to the imminent approval of the digging of the Contorta canal), I don’t think it’s inconceivable that eventually Venice could see itself de-listed from the UNESCO panoply.

This is not the most improbable scenario I’ve ever come up with. Except that I’d love to be able to say “I was wrong.”
