When we think of Rome, we think of the Colosseum with its graceful arches and
Saint Peter’s Square, designed by Michaelangelo. We don’t often think of the
Eternal City’s oldest wonder: the Tiber River. But one American artist has. New
Yorker Kristin Jones creates public art that often focuses on nature and time. She
has found a muse in the trash-filled Tiber and wants to clean it up starting with a
small stretch. Nancy Greenleese reports from Rome:


Along the Tiber, it’s “pazzo,” or crazy. Motorscooters and cars whip by near a
bridge that spans the river. Kristin Jones stands here, gazing down at the far more
tranquil river below. She decides to head down the stairs:


“We’re descending 36 feet below the street level into the channel or the gully that is now
the Tiber.”


Grafitti covers the stone walls and trash bobs in the water. It’s dirty and secluded
and Jones wants to change that with the creation of a water-themed “piazza,” the
gathering places that dot Italian cities. Jones remembers when she first saw the Tiber.
It was 1983 and she’d just arrived in Rome on a Fulbright scholarship:


And as a New Yorker I said to myself, “Oh my God. There’s something parallel here?
What is this?”


And then it hit her like a vision from the nearby Vatican:


“This is like a Central Park. Central Park is such an abstract miracle, I mean, it’s really
nature in the middle of the city and you walk there and you see leafs tremble and you see
real grass and you see a real squirrel. You even can collect mushrooms in Central Park.”


Jones could collect an impressive collection of beer bottles here. Homeless people are
camped nearby and the stench of urine is overpowering. Italian have little love for the
Tiber. It used to frequently flood, prompting the construction in the 1800s of walls that
hold – and hide – the river below the streets. Jones, however, wants people to visit and
appreciate the Tiber:


“Well, if you think about it, perhaps you could consider it to be the most ancient
monument in Rome (laughs).”


The city was founded along its banks nearly 3000 years ago and water has flowed
through its history. The Roman Empire’s aqueducts revolutionized water transportation.
A flooded Colosseum once held mock sea battles. Today, Jones says tourists still come
for the water:


“The fountains in, throughout the historic city have always been a sort of showy element
of power and exuberance and fun and yet the main artery is completely neglected.”


Until now.

Locals and tourists stroll along the proposed piazza on a recent evening. Jones’ group
group Tevereterno, or Eternal Tiber, organized this event to promote the 600 meter
stretch. Supporters would like it to eventually host modern art exhibits and conferences
focused on water. Tonight, musicians perform and more than 1000 candles line the
river’s banks. Allegra Zapponi checks out the scene and reflects on what the Tiber means
to Italians:


“I think in the last 50 years of the last century, like the place for the rubbish. Everything
that you want to give away, you throw it in the river (laugh).”


But Kristin Jones and her supporters believe that the piazza would be a tributary for
getting people to the river and encourage its cleanup. However, arts advocate Luca
Bergamo, who has worked for two mayors, says Jones’ enthusiasm might not be enough
to get the project afloat:


“The biggest challenge is that you don’t find people investing in risky things in this
country. This is not risky but it’s unknown, not understood.”


Change is resisted in Italy, a country often strangled by its historic past. And politicians
can’t justify spending money on the Tiber when resources are scarce for more famous
monuments.


As couples at the party listen to an avante garde audio composition, attitudes might be
changing. The city has added the proposed renovation of this stretch of the Tiber, the
Piazza Tevere, to its new city plan. Jones says it’s time to hand the project over to
Italians:


“They’re all applauding me and trying to get me to keep doing it. And I keep trying to
step back and say, ‘It’s YOUR river. Hallelujah! See the potential, see the potential. I see
the potential.'”


She has agreed to plan next year’s celebration on the Tiber. In the meantime, there’s a
reminder of what could be. Jones has surreptitiously posted on the river’s embankment a
replica of the stone signs that mark Rome’s piazzas and streets. It says “Piazza Tevere.”

Keeping Invasive Species Out

Harbors in the United States risk biological pollution every time a foreign ship comes into port. The ships often carry foreign aquatic animals that can cause environmental and economic damage. Lester Graham reports the problem is known, acknowledged, and still the government has not taken the measures needed to stop the problem:


Ships use water for ballast to keep the ship balanced and level. But taking up ballast water in a foreign port also takes up aquatic hitch-hikers, such as zebra mussels.


Most cargo ships on the Great Lakes are American or Canadian and just travel within the lakes. Ships from overseas only make up a small fraction of the cargo traffic to ports in the Great Lakes, but those ships have brought in dozens of invasive species that have hurt the ecology of the lakes. Some invasives eat the eggs of native fish. They compete for food. They cause disruptions that have led to massive die-offs of fish and waterfowl such as seagulls, loons, and terns.


It has also cost industry, and ultimately you. For example, it costs to clean out zebra mussels from water intake pipes, and some fish have become more scarce.


Jennifer Nalbone is with the environmental organization Great Lakes United. She says it’s a real problem.


“One of the greatest tensions that exists in the Great Lakes today is between commercial navigation development and the invasive species that are being brought into the region by a small subset of ships that are operating on the Great Lakes.”


Nalbone says government agencies could require ships from overseas to install filters or treatment systems that would stop the aquatic nuisances from being brought on board. But those agencies have not done anything. They say Congress hasn’t instructed them to do anything.


And Jennifer Nalbone says many in Congress don’t understand much about invasive species and ballast water.


“It’s very difficult to get things done in D.C. when key federal leaders and committees are not from the Great Lakes region, and they want their own projects advanced first.”


You can imagine if you’re a Congressman from Oklahoma, or Idaho, or Arizona, invasive species from ballast water likely are not at the top of your to-do list.


The only thing that is required is overseas ships have to exchange their ballast water with ocean water once they’re at sea. The idea is to flush out the invasives. It’s not been entirely effective because new invasive species have been brought into the Great Lakes since the policy went into effect.


Allegra Cangelosi is a senior policy analyst with the Northeast-Midwest Institute. She’s been working on the Great Lakes Ballast Technology Demonstration Project for a decade now, trying to find solutions to the ballast treatment problem.


Cangelosi says since the ballast water exchange policy was put into effect, not much else has been done. She says the hold up now is because some government officials don’t want to do anything until a perfect standard is set for ballast treatment. Cangelosi says it doesn’t have to be perfect.


“No, I mean, I’ve been in this business, I’ve been following this issue since 1989 and this is the worst stalemate I’ve ever experienced on this issue area. And, I think what we need to do is just get real and start to require ships to use treatments that are available. So, if we can get ships to use even an imperfect treatment system that is better than what we’re doing now, that’s the road to getting to the perfect treatment system, and it’s the road to improving prevention in the near term.”


The overseas shipping industry says it’s working on the problem. The International Maritime Organization has set a standard for ballast water treatment, but, it’s voluntary. Almost no foreign ships have volunteered because they don’t want to choose a system that might not meet the standard the U.S. government will someday set.


Adolph Ojard is the Executive Director of the Duluth, Minnesota Seaway Port Authority. He says ballast treatment will happen, eventually.


“I don’t have a timeline right now, but I tell you what, we know the problem is contained within the ballast tank of a ship. So, it’s identified. I would think within the next few years we would have a system that is effective, and then we’ll go through an implementation phase.”


But those who are concerned about damage to the Great Lakes fishery and the entire ecological system say right now more invasives are being introduced by foreign ships every year.


Jennifer Nalbone with Great Lakes United says those foreign organisms have caused enough damage already.


“We certainly have enough information to take action. We know that there are tremendous impacts. So, we don’t need to have yet another species come into the lakes before we say ‘let’s do something now.'”


The U.S. Environmental Protection Agency has been ordered by a judge to treat ballast water like pollution. It’s unclear whether the EPA will accept or challenge that ruling. Meanwhile, quietly, some economists and others are wondering if the price the invasives cost the economy is worth the commerce that the relatively few foreign ships bring to Great Lakes ports.
