After 30 years of debate and testing, work began on the 'Moses' flood barriers
in 2003. The massive construction project, due to be completed in 2012, is
expected to cost 3.5 billion euros .
But in the wake of widespread concern among Venetians and environmentalists over
the impact of Moses on the lagoon, Mayor Massimo Cacciari called on Monday for a
"review" of the project .
A measure approved later by the city council called for a pause for thought and
"the possibility to test simpler and less costly solutions" to Venice's
perennial flooding problems .
Cacciari pointed out that ultimately the government - which is footing most of
the bill - will have the final say on whether Moses continues to be built and,
if so, in what form .
He argued that first of all studies should be carried out to gauge whether the
environmental impact of Moses is sustainable and whether it can be reduced in
any way . An assessment on the impact of Moses in 1998 came to negative conclusions, he
noted .
At the same time alternatives to the metal barriers could be looked at to see
whether they offered a better - and possibly cheaper - solution .
Work done until now was "not to be thrown away", he said, adding: "It's a
question of continuing in a way which is compatible with whatever comes out of
the review" .
Supporters of Moses saw the mayor's move as a strategy to stop construction work
and eventually block the project altogether .
"This is senseless. Its environmental bigotry against the defence of Venice and
its monuments," said art critic and former culture undersecretary Vittorio
Sgarbi .
Moses consists of 79 barriers, which would lie on the seabed at the three
entrances to the Venice lagoon for most of the time. Thanks to compressed air
pumped into them, they would rise up when high tides were forecast and so stop
seawater entering the lagoon from the Adriatic Sea .
Flooding is a constant problem for Venice and the picturesque St Mark's Square
is covered with water dozens of times every year .
The previous centre-right government in Rome adopted Moses as one of the jewels
in its nationwide crown of major infrastructural projects but the attitude of
the new centre-left government - of which the Greens are a member - has still to
emerge .
According to experts, Venice is increasingly subject to flooding for three
reasons: the lagoon floor is rising because of incoming silt; the extraction of
methane gas in the sea off Venice causes its islands to sink; and sea levels are
rising in general because of global warming .
Moses is opposed by environmentalists worried about the impact of the system on
the lagoon's ecosystem and by many Venetians who argue that the money could be
spent on cheaper, less damaging solutions .
The European Commission opened infringement procedures against Italy earlier
this year in connection with the environmental impact of the flood barriers .
The European Court of Justice has already found Italy guilty of breaking a 2000
EU nature directive by failing to set aside protected areas for the birds who
live around the lagoon .
The mayor is in an awkward position because he was voted into office last year
partly on the back of promises to 'review' the flood barrier project. But not
all his allies in city hall agree with the idea of slowing down or halting
construction .
With Cacciari's supporters divided and opposition councillors keen to continue
building, it was unclear what the outcome of Monday's concil meeting would be .
Cacciari said he wasn't proposing dropping the Moses project altogether, but
doing a series of tests and studies to see whether its environmental impact
could be lessened and its effectiveness improved .
