CLIMATE CRISIS

Italy must learn to cope with drought-inducing weather: minister

Italy's long-running drought is caused by climate change and the country must adjust to this new reality, Italy's agriculture minister said in an interview published on Monday.

After heavy rain following another spell of drought resulted in deadly flooding in northern Italy last week, Agriculture Minister Francesco Lollobrigida said Italy must adapt its infrastructure to cope with the changing climate – but said CO2-reduction measures would be too damaging to Italian industry.

Lollobrigida told news agency Reuters Italy needed to build more reservoirs to hold water reserves, urgently patch up leaky pipelines, repair dams, and consider moving some types of crops away from increasingly arid areas.

“The drought is not a [one-off] emergency, it is linked to climate change,” said Lollobrigida, a senior member of the ruling, far-right Brothers of Italy party.

Italy suffered its most severe drought in 70 years in 2022, and a dry winter has raised fears that 2023 could be even worse.

“We must consume water better in agriculture, invest in research, use new drip irrigation methods and underground irrigation, and be organised to use every drop of water in the best way without any dispersion,” Lollobrigida told Reuters.

He said leaky pipes were a major problem, with 41.2 percent of water lost from the national network on average before reaching the taps. By comparison, Germany had a water dispersion rate of 6.5 percent, the minister said.

Another solution would be to repair dozens of Italy’s nearly 530 dams that had fallen into disrepair, he said, estimating that 30 percent of the country’s dams were obstructed.

“We have a water catchment of just 11 percent and therefore we do not keep rainwater,” he said.

He added that precipitation had not radically decreased, but came in shorter, sharper bursts, as happened last week, when heavy rain caused severe flooding which left two people dead in the Emilia Romagna region.

Severe rainfall meant rivers in the region overflowed, causing damage to property and agriculture. About 450 people were evacuated from their homes.

The violent storms, far from bringing relief from the drought, worsened the situation as flood water damaged vineyards and farmland, according to the Coldiretti agricultural association.

Despite acknowledging that drought was caused by climate change, the minister reportedly brushed aside criticism that the government had sought to block EU efforts to cut carbon emissions.

In recent months, Italy has been pushing the European Union to weaken a directive aimed at improving the energy efficiency of buildings, and has questioned a push to reduce industrial emissions.

The Italian government has also pushed back against plans to phase out diesel and petrol cars by 2035, with ministers saying Italy is too far “behind” in the transition to electric vehicles to be able to meet this deadline.

“I think we need to be more pragmatic and less ideological,” Lollobrigida told Reuters, suggesting CO2-reduction measures such as those proposed at an EU level run the risk of turning Italian industry “into a desert”.

In April, the government appointed a commissioner to lead a drought task force of senior officials from various ministries.

The Italian government has not yet announced any concrete measures to tackle droughts and the other effects of the increasing number of extreme weather events hitting Italy.

VENICE

Italian scientists predict parts of Venice will be underwater by 2150

New research by Italian scientists estimated that large areas of Venice including the famous Saint Mark’s Square will be submerged by 2150 due to rising sea levels and the city’s sinking foundations.

Italian scientists predict parts of Venice will be underwater by 2150

A new study carried out by scientists at Italy’s National Institute of Geophysics and Volcanology (INGV) found that tide levels in the Venetian lagoon are rising at a rate of approximately half a centimetre per year on average. 

Researchers predicted that the rise will result in some areas of the main island being permanently underwater by 2150, with Saint Mark’s Square forecast to be constantly submerged by 70 centimetres of water. 

The exact increase rates weren’t the same across the lagoon, with figures ranging from 4.22 millimetres at the Venice Lido to nearly 6 millimetres in Chioggia, in the southern section of the lagoon.

The study, which combined records from Venice’s tidal centre with satellite data on land subsidence, also concluded that the western side of the city, which includes the Santa Croce, San Polo and Dorsoduro districts, will be among the worst-affected areas.

INGV researchers pointed to rising sea levels in the Venetian lagoon as being emblematic of a wider phenomenon registered across the entire Mediterranean sea, whose levels have increased by some 18 centimetres since the beginning of the 20th century.  

“Sea level increase, particularly if accelerated locally by subsidence, is leading to increasingly severe and widespread coastal erosion, beach retreat and marine flooding with very significant environmental and socioeconomic impacts for populations,” INGV researcher Marco Anzidei said.

Venice has experienced increasingly frequent severe flooding in recent years as the city was hit by some 58 high tides (acque alte) of 110 centimetres or more between 2019 and 2023 – more than twice the number recorded between 2009 and 2013.

A 187-centimetre acqua alta – the second-highest tide in Venice’s history – caused the death of two people and hundreds of millions of euros in damage in November 2019.

A long-planned system of mobile barriers aimed at protecting the city from high tides became operational in late 2020 and has since been activated on over 80 occasions. 

But the MOSE sluice gates, which are placed at the lagoon’s main entry points and raised whenever high tides hit, have long been criticised by experts as just a short-term fix to rising sea levels.

A 2021 report from the Intergovernmental Panel on Climate Change predicted a rise in the mean regional sea level of 28-55 centimetres by 2100 in their most optimistic scenario, and 63-101 centimetres in the worst-case scenario.

Experts have forecast that, in either case, the barriers will have to be raised so frequently that they will endanger the survival of Venice’s port industry and the lagoon will gradually turn into a marsh, which may ultimately result in the loss of many local wildlife species.
