Boretto, province of Reggio Emilia, northern Italy. Below the bridge on the entrance to town the river is nearly invisible. The concrete foundations of the pillars, that are often below water, are hanging. The place Italy’s longest river, the Po, as soon as flowed, there may be now a big seashore. The place there was as soon as a riverbed, girls and boys now enterprise on foot. A pair walks with a canine and throws sticks into the space. The animals rush to retrieve them and fortunately discover an space that’s usually off-limits.
It’s April 2023. Not a single drop of rain has fallen for 2 and a half months. The river’s move has fallen dramatically, elevating fears of a repeat of what occurred in 2022, when the Po reached its lowest move in historical past. “The river is at a particularly low stage for this season,” confirms engineer Alessio Picarelli of the Interregional Company for the Po River (Aipo).
The company, headquartered in Boretto, conducts hydrographic surveys. The meatori – the employees liable for checking the depth of the river – depart from right here and the seven different stations each day. The company then points a bulletin to report on navigability situations. It’s a privileged observer of the so-called skinny: the durations by which the Po suffers.
The shortage of rain, mixed with the absence of snow within the mountain ranges, is placing nice stress on Italy’s largest river. The snow now not falls on the identical tempo and the Alpine glaciers, reservoirs of fossil water, are shrinking. Furthermore, if it doesn’t rain, your complete system will enter a disaster. It is a scenario that may doubtless develop into extra widespread within the close to future.
“These flows are usually recorded in August,” Picarelli stated. ‘However with a further reality: in the summertime water is used for agriculture.’ In different phrases, if farmers pump water for irrigation, the issue will develop into even worse. ‘For years, predictive local weather fashions have been telling us about the potential for the Po Valley drying up. That is taking place earlier than our eyes. That is the pattern. However in fact the present scenario can change at any time.’
And that certainly occurred. In mid-Might 2023, an uncommon quantity of rain fell on a number of components of the Po Valley, inflicting a number of rivers and streams to overflow their banks. The Po finally remained inside its banks, however lots of its tributaries overflowed, with catastrophic penalties and a heavy human toll: 16 deaths and 23,000 displaced.

An absence of imaginative and prescient
The Po is a litmus check for the more and more obvious penalties of the local weather disaster in Italy. Within the middle of the Mediterranean, the nation is a local weather hotspot, the place the consequences of world warming are most pronounced. Rising temperatures, along with a succession of utmost climate occasions, are placing stress on the realm.
Based on the European Extreme Climate Database, Italy skilled 3,192 excessive climate occasions in 2022; About 2,766 have already been registered within the first 9 months of 2023. That is an astronomical determine, because the quantity not often exceeded 100 between 2000 and 2010.
“In Italy and all through the Mediterranean, world warming is having a particular impact: not solely is the typical temperature rising, the extremes are additionally rising as a result of the circulation of the ambiance is altering,” explains atmospheric physicist Antonello Pasini. ‘We was once used to the excessive atmospheric stress that at all times got here from west to east, particularly because of the well-known anticyclone of the Azores. This anticyclone was a buffer of steady air and guarded us from the climate disturbances in Northern Europe, but in addition from the African warmth. Now, anthropogenic world warming has precipitated the tropical equatorial circulation to develop northward. This modification implies that African anticyclones, beforehand completely current within the Sahara, enter the Mediterranean Sea and attain Italy. After they lastly withdraw, chilly currents transfer in and meet the previous heat and moist air, creating an enormous thermal distinction. And that is how excessive climate occasions occur.”
Fluctuations between alarmingly low water ranges and catastrophic flooding appear to be the brand new pattern on the Po, as on a number of different Italian rivers. The 2022 drought was the worst in 200 years, inflicting agricultural yields and hydropower manufacturing to plummet. Based on Italy’s largest agricultural affiliation, Coldiretti, water shortages precipitated a ten p.c drop in Italian agricultural manufacturing, with farmers estimated to have misplaced round six billion euros. This 12 months was not significantly better: the succession of droughts and excessive occasions precipitated large harm on an analogous scale.
‘We’ve got to name issues by their names: we’re in the midst of a local weather disaster.’ Giuliano Landini, born and raised within the space, is the residing reminiscence of the river. He’s the captain of the Stradivari, Italy’s longest inland cruise ship. On the helm of his ship, anchored within the port of Boretto, he’s desolate. He seems on the river and shakes his head.
The captain has complained for years a few lack of imaginative and prescient for Italy’s largest river. ‘The present local weather state of affairs clearly exhibits us the weak spot of the system. Both we cry as a result of the Po is dry, or we reside in concern of floods. The very fact is that the river has been left to itself. I at all times ask myself: why do the Seine, the Danube, the Elbe – all the most important European rivers – stay navigable whereas the Po suffers?”
For Landini, the answer is obvious: to kissor basinization. This plan would include dams with hydroelectric energy stations and locks. ‘This implies the river is at all times navigable and no water is wasted when there may be ample water. As a riverman, like my father and grandfather, I can guarantee you that we’ll not get out of this till we handle the water as soon as and for all by means of dams on the Po.’
A earlier marketing campaign within the space required 5 dams. Just one was constructed, on Isola Serafini within the province of Piacenza, with a basin and a hydroelectric energy station. The opposite plans have been placed on maintain. And it was determined to let the river move freely.
Basinization just isn’t an answer shared by everybody – and positively not by environmentalists, who concern too radical a change in ecosystems. However a part of Landini’s argument is indeniable: the Po is a forgotten space. What was as soon as a vibrant place, with its personal tradition and financial system, is now on the margins, ignored by politicians and even those that reside alongside its banks.
Overused and undervalued
“No one likes to speak concerning the Po,” Landini continues. ‘But the water is helpful for everybody: for agriculture, business, power manufacturing and extra.’ It’s the gigantic Italian paradox. A 3rd of the nation’s inhabitants reside within the Po Valley, the Po Valley. It generates 40 p.c of the nationwide GDP, 35 p.c of agricultural manufacturing and 55 p.c of hydropower manufacturing. But the Po is handled as an impediment and never a useful resource. And even worse: as a reservoir to attract water for the numerous industrial farms within the valley, to gather gravel or to make use of as a sewer for industrial wastewater.
‘The world is overexploited. It’s no secret that it’s the most polluted area in Europe,” stated Paolo Pileri, professor of Territorial and Spatial Planning on the Polytechnic College of Milan. He explains that the floods in Emilia-Romagna final Might had such disastrous penalties as a result of the realm had been made weak by human exercise. ‘Between 2020 and 2021, Emilia-Romagna would be the area with the third highest land consumption in Italy. In only one 12 months, some 658 hectares had been landfilled, equal to 10.4 p.c of the nationwide complete. In just some years, the area’s waterproof floor has reached 8.9 p.c, in comparison with a nationwide common of seven.1 p.c. We all know very nicely that water doesn’t filter by means of asphalt, however flows shortly from it, accumulating in amount and power and inflicting harm and casualties.’
It’s virtually as if the Po and its tributaries, made invisible by human exploitation, are taking again the area stolen from them. ‘The Po is sort of a wounded large. It swells and dries at will. It turns into widespread with water when agriculture is thirstiest. And it causes hardship and distress for the residents who turned their backs on him,” Landini says poetically.
Confronted with these erratic river tendencies, the numerous stakeholders who use the Po’s waters are attempting to provide you with options. ‘Information from latest years exhibits that drought is changing into a structural downside. The challenges of local weather change impose a brand new actuality by which we can not blame irrational use of the useful resource,” stated Francesco Vincenzi, an agricultural entrepreneur and president of the Nationwide Affiliation of Land and Irrigation Water Administration. Agricultural organizations are lively in proposing options to an issue that’s important to them. “To deal with the rising water scarcity, it’s essential to launch an infrastructure plan to adapt irrigation canals and the safety of the water provide,” Vincenzi added.
The Nationwide Restoration and Resilience Plan, the financing instrument adopted by the European Union after the Covid-19 pandemic, allocates 880 million euros, exactly with the goal of creating the irrigation system extra environment friendly and constructing retention basins. ‘These mini-reservoirs will make it potential to avoid wasting water in a multifunctional perspective, each for agriculture and for power. Provided that we retain solely 11 p.c of water right this moment, it’s pressing to hold out these works.’
Everybody appears to agree on the necessity to preserve a useful resource that’s changing into scarcer each day. “However additionally it is essential to query the agricultural mannequin that’s dominant within the Po Valley,” Pileri provides. ‘Farmers complain about an ecosystem that has develop into out of steadiness, however it’s the identical farmers who partly precipitated this. To present an instance: within the central a part of the Po there are enormous expanses of corn fields, a crop that requires lots of water. This corn just isn’t used for human consumption, however to feed pigs on intensive farms and to make biogas. Does it make sense to make use of water for the manufacturing of meals and power as an alternative of merchandise for human consumption?’
Based on Pileri, the one resolution is to rethink the event mannequin: that will imply stopping land consumption, altering manufacturing paradigms and rethinking our relationship with ecosystems. However his reasoning doesn’t discover a lot help. Regardless of the repeated disasters and intensive harm to folks and property, the battle in opposition to the local weather disaster just isn’t on the high of the Meloni authorities’s agenda.
Italy is among the few European international locations that doesn’t have a nationwide local weather change adaptation plan. A draft plan has been ready on the Ministry of Housing, Spatial Planning and the Setting since 2017, awaiting an analysis that by no means materialized. Some members of the governing coalition have repeatedly stated that world warming is an overrated downside.
The Po Valley’s strategy mirrors that of the Italian authorities to the local weather disaster as a complete. Till the following drought or catastrophic occasion, when indifference will quickly give technique to counting the prices and lamenting an ‘inevitable’ and ‘unpredictable’ misfortune.
