The torment of our great river Po. But will we do something to save him? – Corriere.it

From Gian Antonio Stella

The current water crisis will not be temporary. In Italy, in a century, water availability has fallen by 19% and the outlook is not good. From the US to China, the problem affects everyone

How many sacrifices are we willing to make to save the Greater Salt Lake? ask her on The New York Timesfollowing a disturbing investigation published by the same newspaper (a story I’m ashamed to admit has escaped my personal radar) Nobel Prize winner Paul Krugman, who brushes up on his most important topic and replies: If we are already on the edge of the abyss, why is humanity not yet determined to respond immediately and seriously to contain the disaster?

Good question for us too: How many sacrifices are we willing to make to save Po? The pictures on the first pages are enough to understand the agony. I haven’t seen such shoals since 52. That was the year after the flood of November 51, when the flood of the river, orchestrated for centuries by Venice and built for the Lord’s sake, overshadowed everything, and widened its disastrous width over the centuries. The largest surface of Lake Geneva. It was not necessary, dry, for the Paulsane who had already taken the road to Turin, as if they wanted to remain bound by the river …

The data released these days, starting with the data of Meuccio Berselli, Secretary of the Basin Authority, are known. Water crisis in more than 125 municipalities, movement of tankers in Piedmont and Lombardy, accelerated water flow from 450 cubic meters per second to just over 300 cubic metersthe salty wedge that brings with the tide sea water to enter the river more and more, the collapse of 40% of the GDP of agriculture and 55% of the incoming energy production, fishermen in crisis also because of the parallel the arrival of the voracious blue crab aggression from the Americas, the fear of overheating and the consequent On it from the infestation of large algae that can suffocate the clam …

Will he pass the night? The danger many deceive that this shoals may be temporary. It is set to be chased, sooner or later, by the return of absent rain for more than four months (minus 42% of expected rain) and as a result in areas like Piedmont, as Luca Mercalli recalls, only 94 mm of rain fell from December through May for a value Normal 376 mm. Maybe it rained! In fact, Stefano Mariani from Ispra explains, the situation has been getting worse for some time. Between the thirty years 1920-1950 and the thirty years in which we live, for example, the drought increased so severe that the water available in Italy decreased by 19%. And it risks getting worse in the future. So much so that in the most pessimistic hypothesis of scientists, the water flow could be reduced by 90% in 2100. A nightmare. Moreover, in a country like ours, which is blessed with little abundance, 5.2 billion cubic meters out of the 9 (!) are wasted for civilian use because it is unable to manage much good. Which could be in short supply in the near future. It suffices to mention one of the current figures of the Po Basin Authority: the current flow rate in Pontelagoscuro is less than 90%. goosebumps.

Will for talking about a surprise. Although water is strictly dependent on water infrastructures, it has been on the sidelines of our public investments for far too long, as Mario Tosi deplores in the preface to the disturbing book Italy waterWritten by Erasmo de Ingles. A sacred condemnation of demagogues, cunning, and profiteers as if water were an asset to be managed without costs and problems could be solved with a magic wand. And let’s get back to the topic: Since it is necessary to change everything by taking a part of the responsibility, what sacrifices are we willing to make: immediately? It applies to us, it applies to America, it applies to everyone…

Not too little time, says Krugman: too little. Last summer, as The New York Timesthe water level in Great Salt Lake It’s at an all-time low and is likely to fall further this year. The surface of the lake that covered it at the end of the eightiesUSGS About 5310 km (14 times Lake Garda), reduced to less than 1609: less than three times Garda) and the deterioration can be exacerbated with serious consequences for deposits of arsenic, antimony, copper, zirconium … countless times, nature to draw rivers and lakes. A few generations is enough to destroy everything. Think Owen Lake, on the edge of California, where, a century ago, Los Angeles fetched the water it needed to develop. Covered over 100 square miles: dead. Its poisons kill today’s population.

There are a lot of dead or dying lakes. Russia’s mighty Aral ship, half the Adriatic, but drained and killed by Soviet industrial adventurism while fishing boats (I’ve been fishing for two tons a day, Kalig Abzamy told Maurizio Cerrici) was swallowed up by the sand. Lake Coruña, near Thessaloniki, which used to be about the width of Lake Lugano but today can be crossed on foot. Lake Chad, on its shores 22 million people from Chad, Cameroon, Nigeria and Niger live in perpetual conflict: it was the fourth largest freshwater basin in Africa after Lakes Victoria, Tanganyika and Nyasa … yes narrow, compared to the vast expanses of distant times (400 thousand km: more From the Caspian Sea), to the disputed pond: 1350 km. Three times the size of the Venetian lake.

Not to mention the disasters caused by the Great March of Industrialization in China. It suffices to mention the disappearance that he narrated timesAmong the 28,000 streams that have disappeared from the maps of the Asian giant. Where in the same period, let’s say for about forty years here, 243 or so lakes have disappeared as well, according to the Nanjing Institute of Geography and Lacology. Among them, Lake Poyang, China’s largest freshwater lake, has decreased by more than 90%: from more than 3,000 km to less than 200 km.

Disasters resulting from neglect, superficiality and indifference to environmental issues that today Pope Francis denounces every day.
. Disasters that can still be contained at the last minute: What happens to Great Salt Lake rather ugly. But what I found really frightening is what the report says about the lack of an effective response to the lake crisis and our ability to respond to the broader, and already existing, threat of climate change. Quoting a very senior banker who said a month ago in an official letter, who cares if Miami will sink six meters underwater in 100 years? The pursuit of short-term profits or political opportunity is, in a sense, a betrayal of humanity.

Certainly, he admits, global climate change has helped reduce snow cover, which is why Great Salt Lake diminished. M.
The problem lies in domestic water consumption; If this consumption can be curbed, then Utah need not worry that its efforts will be thwarted by the Chinese or alternativeOmani Rial. The threatened region would have to accept modest sacrifices, some of them little more than inconvenience, to avoid imminent disaster. But that doesn’t seem to happen to us. What if we can’t save a file Great Salt LakeWhat is our chance to save the planet?

In short, everyone does their part. Starting with those who make the laws. It must impose a turning point. Moreover, since we were distressed by the war in Ukraine, we must remember that water crises, according to the latest UN reports on Water development in the worldled to the dramatic proliferation of wars over water, which recently rose to 263. That was not enough, adds Erasmo d’Angeles, A study by the World Bank warns that at least 143 million climate migrants will start working by 2050, as a result of drought, water shortages, hunger, famine, epidemics and drying up agricultural areas..
