collapse

the controversial measures with which we have shielded the network a year after the collapse

by

Next April 28 will mark exactly one year to the day that Spain and Portugal faded to black. An unprecedented “zero energy” in the last two decades that left nearly 60 million citizens without electricity, without internet, without traffic lights and with the banking system paralyzed for up to 16 hours. As they reflect in the magazine freenthat day we suddenly discovered that something we take for granted—electricity—is the fragile foundation on which our entire modern life rests. One year after the event, the initial shock has given way to data. We no longer ask ourselves only if such a blackout can happen again, but how much it is costing us to avoid it and if we have really learned our lesson. D-day is about to arrive. Twelve months later, we finally have the “official autopsy.” The European Network of Network Operators (ENTSO-E) published a comprehensive report of 472 pages where he concludes that there was no single cause, but rather a “perfect cocktail” of multiple factors. A sudden surge originating in Spain triggered instability that the system was unable to stop. As we have already explained in Xatakathe failure can be defined as “operational blindness.” The renewable plants operated with a fixed power factor; They did not know how to read the network surge and, for safety reasons, they disconnected suddenly, causing a rebound effect. Besides, as he adds BBClocal generator voltage controls were not fully aligned with operator requirements. The crisis required millisecond reflexes, but tension control was done manually. In fact, if Europe did not fall like a house of cards, it was due to an almost miraculous technicality: a relay in the Hernani substation (Gipuzkoa) acted like a “fusilazo”, cutting the connection with France in milliseconds to shield the continent. Ironically, just ten minutes later, it was that same interconnection that served as assisted breathing to resuscitate the system. The big question: what has Spain done differently? The fear of a new blackout has changed the rules of the game, but at a high price for the citizen. Electrical Network has imposed a “reinforced model” of operations. This means that they prioritize safety over cost, keeping more expensive and stable backup plants on, such as gas combined cycles. The result? The Spanish They have been paying an extra cost of 666 million euros In these eleven months only in “adjustment services”, which have shot up 43%. In the legislative sphere, the Government has approved the Royal Decree-Law 7/2026 to streamline bureaucracy through the “Renewable Acceleration Zones” (ZAR). However, experts warn thatSince there is still no structured capacity market, investing in the necessary storage systems (batteries) continues to be a financial risk for developers. There’s more shielding going on. The collapse not only left us in the dark, but it left us cut off, although in a very uneven way. While some completely lost the signal, others managed to maintain it thanks to the logistical efforts of some operators. To avoid this coverage lottery, the CNMC has proposed that Telefónica, Vodafone and MásOrange offer a “national roaming” plan in case of emergency. If your operator’s network goes down, your mobile phone would automatically connect to the competition, based on the Swedish model. Added to this is the request to make the alert system (ASA) mandatory in cars with digital radio (DAB+), to send warnings to the population immediately even if the internet is down. The false culprit and the new energy guzzler. After the collapse, many were quick to blame green energy, but the reality is different. As explained from freenthe problem is not that Spain has a lot of solar and wind energy, but that the electrical grid is still stuck in the 20th century, designed for fossil power plants and not for a decentralized system. In fact, Spain is a fascinating laboratory. According to EUObserverthe country has managed the recent price crisis caused by the Third Gulf War much better than its European neighbors thanks to its enormous solar shield. However, the trauma of the blackout has caused an absurd side effect: operators are so afraid of overloading the grid that they force solar and wind farms to disconnect more frequently. Curtailment (clean energy generated that is thrown away) has gone from 2% to 7%. And if that were not enough, the saturated network assumes the imminent arrival of a new energy-consuming giant: the massive data centers for Artificial Intelligence. The exchange of accusations is served. In the offices the short circuit has only just begun. As detailed Financial Times, The National Markets and Competition Commission (CNMC) has opened formal investigations. Red Eléctrica (REE) faces proceedings for “very serious” infractions, while giants such as Iberdrola, Naturgy, Endesa and Repsol face possible fines of up to 60 million euros for “serious” infractions. Besides, as accounted Public, up to twenty open sanctioning files. REE defends itself by ensuring that the opening of the file does not prove its guilt. Meanwhile, a Senate report promoted by the PP directly blames the Government, REE and the CNMC for ignoring known vulnerabilities, according to Reuters. And the tension reaches the limit: electricity companies like Endesa and Iberdrola They have demanded a judge access more than 8,000 calls and emails from REE executives during the hours of the blackout, after the leak of audios where technicians warned of the danger 15 days before. An electric heart that remains at risk. Spain is “a gold mine without a road”, as defined by Patxi Callejadirector of Iberdrola. We have the sun, the wind and the technical capacity. But the great lesson of this last year is that true energy independence is no longer played at the national level, but at the local level, where factories and homes install their own batteries and hybrid panels so as not to depend on the fragile central system. We survived the blackout and avoided another one by reaching for our wallets and operating defensively. But as long as the line procedures last a decade, mass storage … Read more

A year ago, the blackout caused the Spanish data network to collapse. The CNMC believes it has the solution

by

In April 2025 Spain suffered a zero energy of which, precisely now, we are going to begin to pay some of its consequences. I remember quite clearly being cut off, not being able to call or send messages via data connection. However, when I changed locations and arrived at my relatives’ houses, some of them could do it. The fall of telecommunications It was uneven in Spainand the CNMC has published a document with preventive measures in case a similar situation occurs again. What happened. The energy blackout that left Spain plunged into darkness resulted in a large part of the population being cut off from communication. However, some operators They managed to keep their mobile network active for hours. Backup generators, generating sets moved to each area, backup systems… The challenge for operators to maintain coverage in Spanish territory was a titanic challenge, quite dependent on internal logistics, the state of the reserve batteries (some of them run on fuel), and the network infrastructure itself They were variables that influenced such unequal conditions to be experienced. A single network. In its statement, the CNMC proposes that the four giants of the Spanish territory put roaming plans at the service of the population in emergency cases. The experience of other countries shows that it is viable to incorporate roaming plans between operators in case of emergency. In this way, in areas where this was necessary due to the unavailability of service in an operator’s mobile network, the networks could be prepared to quickly enable the basic telecommunications services of the affected users through roaming in the networks of other operators. According to the regulator, this is an “ideal measure to strengthen resilience”, but it is not so easy to apply. Yes, but. What the CNMC proposes is a cross-roaming service between Telefónica, Vodafone and MásOrange, something that requires coordination and agreement between the three giants. The best example is Sweden where, after two years of preparation, any mobile phone can connect to any operator. Go deeper. In addition to this proposal, the CNMC requests the mandatory nature of the alert system HANDLE in those cars with DAB+ radio receivers (the evolution of FM radio). Although DAB+ works via antenna (like AM and FM radio), its signal is digitally encoded. The ASA system allows you to automatically activate a DAB+ radio connected to power, being able to quickly launch alerts. At the moment, there is a distance from proposal to fact.

The California peach industry has suffered an unprecedented collapse. But it will be repeated, it will be repeated a lot, it will be repeated all over the world

by

Richard Lial He lived peacefully in his little house in Escalonnorthern California. He had acres and acres of productive almond trees that he had been exploiting for the last decade. But three years ago, just when costs began to become unsustainable, Del Monte (one of the largest fruit and vegetable companies in the world) made him an offer. A 20-year contract for Lial to exchange its almond trees for the peaches that the company’s large cannery in Modesto needed. Del Monte’s move put on the table some 550 million over the next few years and a business of tens of thousands of tons per season. The problem is that on July 1, 2025, Del Monte Food Corp declared bankruptcythe Modesto plant has closed and, with it, the entire Californian peach industry has collapsed. What exactly happened? Del Monte accumulated a debt of 1,245 million dollars on the day they filed the bankruptcy petition. And the reason is simple: in recent years, the company had been going into debt to make certain purchases in a sector that was in full decline. Today, the world consumes less canned goods and Del Monte executives believed that the only way to survive was to grow and ensure margins. The problem is that, with the rate increase in the months prior to the bankruptcy declaration, interest had doubled to the point of eating into the operating margin (a margin already quite affected by things like Trump’s tariffs that had made cans more expensive). The chaos has lasted for many months, but on February 6 the courts approved the sale of the company in parts. Peach growers breathed easy until they discovered that none of the buyers wanted the plant of Modesto. And why is that plant so important? Well, because Del Monte did not ask farmers to plant the peach they wanted. They were asked to plant the clingstone variety: a peach that simply has no fresh market. The pulp of the clingstone adheres to the bone and makes direct consumption uncomfortable. That is, it is a variety whose only destination is processors. In this case, the Modesto plant consumed 35% of the production of this stone fruit, about 50,000 tons in 2026. They are, to be honest, 50,000 tons that are now almost impossible to place anywhere. But the problem transcends 2026… Because the contracts that Del Monte I was signing Until a few months before the bankruptcy, they forced farmers to make investments of around $8,000 per acre in exchange for the peace of mind that comes with a 20-year contract. They went into debt for it. Many made the transition in 2023. So there are about 140 Californian farmers fgame era and some 1,200 jobs will be lost. But the impact is deeper. And it is not that talking about ‘sector cataclysm’ is not justified, it is that the central issue is the structural dependency that the dynamics of the primary sector are pushing the economy towards. …and that transcends even the peach. Because it doesn’t matter what product we look at: the consequences of financialization are there. It is enough to remember that in 2015 there were only 45 funds specialized in ‘agrobusiness’ in the world; Today they exceed 1,000 and move an enormous amount of money that is radically changed the way everything is managed. The rresult is as simple as it is tragic: Capital arrives, exploits the land as if there were no tomorrow, exhausts the territory’s resources, abuses the local socio-productive fabric and leaves. One day we will realize that there will be nothing left.

The world has been fascinated by the collapse of the Mayans for decades. In reality, almost everything we thought we knew was wrong.

by

They cultivated fields, raised livestock, built some of the most amazing buildings on the planet, developed a rich culture that included advanced astronomical knowledge that still intrigue today to the experts. The Mayans are one of the most fascinating civilizations on the planet. And rightly so. Without it it is impossible to tell the history of Central America. However, little by little and as technology allows us to delve into their secrets, we begin to understand something: much of what we thought we knew about the Mayans was wrong. And that includes its collapse. What happened to the Mayans? The question is very simple. His answer not so much anymore. As our knowledge of the Mayan civilization has expanded (thanks to resources such as LiDAR technology) has also mutated the idea that historians had of its decline. I remembered it recently in Guardian Marcus Haraldsson remembering what we know about Tikalone of the largest urban centers of the Mayans, located in what is now Guatemala. “Sudden and disastrous”? The most recent stele located at the site dates back to the year 869 ADwhich leaves the question of what happened in Tikal from that date on. For a time historians assessed the possibility of a “sudden and disastrous” collapse that marked its fate; But today that explanation seems increasingly distant. Now experts are leaning towards another option: a broad period of decline of around 200 years during which farmers moved north and south and powerful urban centers were abandoned in favor of settlements such as Chichén Itzá, Uxmal or Mayapán, towards the north of the Yucatán Peninsula. There is even talk of the period Classic Terminalwhich goes from the years 750 to 1050. Changing perspective. This perspective has been adapted over the decades and goes beyond the period of decline of the Mayan civilization. “We are no longer really talking about collapse, but about decline, transformation and reorganization of society, as well as a continuity of culture,” comment to Guardian Kenneth E. Seligson, associate professor of archeology at California State University (CSU). “There have been several similar changes in places like Rome. (But) we rarely talk about the great Roman collapse anymore because they re-emerged in various forms, just like the Mayans.” But… What happened? What exactly happened for many of the main Mayan settlements (not all) to begin to collapse towards the 9th and 10th centuries It remains a complex and highly discussed topic. Today the authors point out a combination of factors including changes in trade routes, adverse weather, severe and prolonged droughts and wars, among others. The truth is that in the middle of 2026, researchers continue collecting clues that helps us clear up unknowns about that period. The importance of water. You don’t have to go far back to read new discoveries that tell us precisely about the collapse of the Mayan civilization. Last August a group of scientists published a article in which they basically emphasized the “important role” that “prolonged droughts” played in the Mayan decline. For their study, the researchers analyzed a stalagmite located in a cave in the Yucatan, a true geological and archaeological treasure if its oxygen isotopes are analyzed. The examination revealed a series of periods of severe drought between 871 and 1021, during the Terminal Classic, stages marked by water shortages during which the Mayans found it “extremely difficult” to grow their crops. It may seem exaggerated, but the study revealed eight droughts during the rainy season that lasted at least three years. Not only that. The longest drought lasted about 13 years. Other previous studies, carried out from sediments collected in the Chichankanab lagoon or stalactites rescued in Belizehad already suggested the role that climate played in the Mayan collapse. Question of droughts (and something else). Months after that study, in November, Benjamin Gwinneth, from the Université de Montréal (UdeM), published another that helps complete the ‘photo’. The Canadian institution recalls that between 750 and 900 AD the population of the Mayan lowlands suffered “a significant demographic and political decline” that coincided with “episodes of intense drought.” What Gwinneth’s work questions is whether this collapse is explained only by the lack of water. Curiously, their research is also based on the analysis of sediment samples dating back to around 3,300 years ago. And what exactly did he do? Gwinneth dedicated himself to analyzing samples taken from Laguna Itzán, in present-day Guatemala, near an archaeological site Maya. To be precise, they focused on three “geochemical indicators” that reveal the evolution of fires, vegetation and population density in the area (something they estimate thanks to fecal stanols) for thousands of years. The first conclusion they obtained is that the first settlements appeared in the area 3,200 years ago and for centuries the Mayans cultivated, burned to clear forests and used the ashes as natural fertilizer. It also gradually increased the population of the area. Over time they even changed their “agricultural strategy”, dispensing with fire. A “stable” climate. The second conclusion (and this is the interesting part) is that, unlike Mayan populations located further north that did suffer “devastating droughts”, in Itzán the climate was relatively “stable” thanks in part to its geographical location, near the Cordillera. Curiously, that did not free Itzán from the crisis that they suffered in other areas of the Mayan world. The question is obvious: Why? If it kept raining there, what dragged them into the crisis? “Although there was no drought in the area, the population decreased during the Terminal Classic period. Indicators show a drastic drop, traces of agriculture disappear and the site was abandoned,” Gwinneth points out.which recalls that some archaeologists place the beginning of the Mayan collapse in the Itzán area. Why is it important? Because it suggests that drought (no matter how stubborn) is not enough on its own to explain the Mayan decline. “The answer lies in the interconnection of Mayan societies,” reflects the expert. “Cities did not exist in isolation. They formed a complex network of commercial ties, … Read more

is not to collapse the road

Although each mega-construction that occurs always represents a technical challenge, doing so on one of the busiest points in Spain makes the process even more difficult. The one of Sales Park aims to build a park of more than 16,000 square meters on 16 traffic lanes at the point with the highest vehicle intensity in Spain. Hence the challenge, since the operation must advance without collapsing Madrid. Night operations. Raising a 197-meter structure supported by 128 pillars on the M-30 is complex, but feasible. Just like they count From El Mundo, the truly complicated thing is to do it without paralyzing the traffic of a city of more than three million inhabitants. Javier Nájera, head of the City Council’s structures service, told the media that working on that stretch during the day could cause traffic jams of up to 14 hours a day. That is why they decided to concentrate the most critical works in summer, when traffic intensity drops by 40%, and carry out the most delicate operations at night. Technical challenge. At night, two cranes weighing more than 500 tons take position on the M-30 to advance the construction process. According to counted Nájera in the middle, nothing more than the assembly of these cranes requires about four hours, but they are very useful for lifting concrete beams of up to 200 tons and 40 meters in length. The structure requires 96 of these beams, and at six in the morning of each day worked, everything must be collected as if nothing had happened so as not to hinder traffic. Huge beams that force a plant to close. The beams arrive from factories in Rivas Vaciamadrid and Seville. According to what they tell the media, this is because the Community of Madrid does not have more production capacity for this type of structural elements. Manufacturing a single beam of these characteristics requires the complete closure of an industrial plant. Nájera tells El Mundo that transportation from Andalusia is more expensive, but it would be unfeasible to produce them in a single factory for the pace they need. Rehabilitation. During the initial excavation, pools of water appeared on the hard ground that were not foreseen in the geotechnical studies, Nájera told the outlet. The work had to be readjusted on the fly. Unforeseen events are common in this type of construction, but when working on the main traffic artery in Spain, each day of delay multiplies their impact. In fact, the start of construction on the last day of June coincided with several accidents that caused significant delays, a brief reminder of how tight the margin of error can be. Prepare the land for 1,060 trees. The future platform will support 110,031 tons, including permanent loads and intended uses. Najera account that would resist even the passage of tanks crossing from one side to the other. For the park to function, a triple layer of waterproofing will be installed with asphalt sheets, anti-root meshes and a system of aeration cells so that the trees can grow and develop without problems. The same method was also used in Madrid Río. Eight walkways to save centuries-old cedars. The intention is to connect both banks of the M-30 through eight pedestrian walkways that will meander to avoid damaging the ancient cedars. These walkways will connect the Quinta de la Fuente del Berro park with the green area of ​​Ciudad Lineal, a corridor that would benefit more than 140,000 residents. The lanes are now open, but a lot of work remains. The M-30 recovered all its lanes operational a month and a half in advance of what was planned. Traffic effects are now limited to nighttime hours, although speed is still limited to 50 km/h on this stretch. Of the 128 piles that will support the roof, 73 have already been installed, and the first transverse beams began to be placed at the end of November. With an investment of 78.9 million euros, the project is scheduled to be completed by spring 2027. What comes next. Once the main structure is completed, the installation of the garden areas, playgrounds, calisthenics elements, a small outdoor auditorium, kiosks and LED lighting systems will begin. Of course, until the park shows its first trees, there is still work to do.

AEMET confirms a collapse and snow at 1,000 meters to start Christmas

by

If you thought you had too much of a coat this week, now you’re going to have to think twice. After a few marked days due to unusually mild temperatures for mid-Decemberthe weather is going to change radically with the arrival of the peak days of Christmas. A thermal collapse. So far, the month of December has seen some really warm days where you could easily be out in the sun without a jacket. This is something that has been seen especially in parts of the Mediterranean, Almería and even in the Cantabrian Sea with thermometers that have reached to touch 20 degrees. However, it already has an expiration date. Starting on December 21, coinciding with the official start of astronomical winter, a notable thermal drop is expected. According to AEMET itself This change will not be gradual, but will feel like a drastic collapse in thermometers by this polar jet that arrives from the north that will leave minimum temperatures in the negative and that in general will cause a thermal drop of 3-5ºC. Precipitation map for Sunday, December 21 | Source: AEMET Rain and snow. Before the great drop in temperatures, we will see abundant rains in our territory due to the entry of a new front from the Atlantic. This will mean that this weekend we will see abundant rain in a good part of the peninsula, with special emphasis on northern Spain where significant storms are expected for next Sunday. The Galician coasts are where we will have to keep a close eye, as these precipitations will be accompanied by very strong gusts of wind, which will lead to the appearance of waves that can exceed seven meters in height. Appearance of snow. With the drop in temperature, rain can end up turning into snow in part of the peninsula. In this case, the snow level is expected to drop to 1,000-1,200 meters in the northern third. The most affected areas They will be the communities of Galicia, Asturias, Cantabria, La Rioja, Castilla y León, the Community of Madrid and Castilla – La Mancha. This is bad news, except for lovers of a Christmas under a layer of white. And just this weekend a new operation begins, coinciding with the start of the Christmas holidays. This is something that can cause significant traffic delays in the northern third of the country. Christmas week. We already have Christmas Eve almost here, and there are many eyes on to the weather forecast. For now, the progress that the AEMET has given us after the front on the 21st is that we will have a cold environment with significant night frosts across the peninsula and widespread, although not extreme, rainfall, which will be present especially in the south of the peninsula. But this is something that will not affect the Canary Islands, which will maintain stable weather and normal conditions for the time in which we find ourselves. An extreme change. There is a climate prediction coming from Europe that sees a much more extreme and unusual scenario that may or may not occur. Specifically, the ECMWF points out that there may be heavy snowfall in the province of Seville, Huelva and the south of Badajos on Christmas Eve. This would be something historic, since snow is a strange event to see in Seville, where there has not been a solid snowfall since 1954. That is why this European prediction is really crazy, which logically can change as the days go by, leaving the chances of snow in Seville a disappointment, despite the fact that the low temperatures are going to continue.

Spain fears a major collapse during the August 2026 eclipse, so it is already starting to design emergency plans

by

Spain has activated the machinery to prepare for one of the most anticipated natural phenomena with the greatest logistical impact: the total eclipse that we will experience next August 12, 2026. A phenomenon that will cross the north of the country and that will make Spain the focus of all lovers of these phenomena that nature gives us, and it is logical, since it is the first total solar eclipse visible from continental Europe since 1999. The challenge of having thousands of people gathered together looking at the sky, and also added to the large number of tourists who will arrive in the country, makes the Government has asked the autonomous communities to prepare security and mobility plans. Something that can be similar, for example, to the organization of a soccer World Cup, but concentrated in a few hours. In order to manage the logistics of this important date, the central government activated an inter-ministerial commission that recently had a second meeting with the regional representatives. The objective is to be able to have a joint response to the massive influx of visitors mainly to the north of Spain. And it is no wonder, since in experience we have in mind the ‘Great American Eclipse‘ of 2024 where thousands of people ended up collapsing parks and roads, even where the eclipse was partial. And we want to avoid as much as possible that this ends up being chaos in Spain. The estimate. We are not talking about a few thousand people interested in these phenomena, but the Government proposes that millions of people can move to follow the strip of totality that will diagonally cross 13 autonomies and at least 27 provinces from Galicia to Aragon, passing through Castilla y León, Cantabria, Navarra and La Rioja. The eclipse will occur just at sunset, with the Sun going completely dark for a few minutes while the Moon blocks its disk, peaking at 20:28. The zone of total darkness will also cross a part of northern Portugal, the extreme west of Iceland and an unpopulated strip of Greenland, but Spain will be the only country where it can be observed with full guarantees and from inhabited places. And in the case of Spain in particular, the truth is that it is something historic, since It will be the first to be seen from the Iberian Peninsula in more than a century. What is requested. The central government wants to anticipate problems that may arise, such as an emergency, which is likely when we talk about a mass of people at a specific point. But in addition to this, contingency plans must also be prepared on roads due to the large number of trips that can occur in a very short period of time. The problem here is that we are in a country that is not centralized in a single administration, and that is why the cooperation of all the autonomous communities is essential. The Ministry of Science emphasize which, in addition to guaranteeing safety and mobility, seeks to promote correct scientific dissemination and avoid risks such as the use of non-approved solar glasses, an aspect highlighted by Cigudosa to prevent damage or fraud in eye protection during observation. The problems. Among those they want to address is undoubtedly the possibility of having accidents on roads, kilometer-long traffic jams and blocked access to cities. This adds to the possible overload of the infrastructures of emptied Spain, since many observation points are located in rural areas or coastal areas with limited resources. This means that it can be very easy for secondary roads to collapse, mobile coverage towers to be saturated, and for there to not be enough fuel or food for all the spectators of this historic event in our country. Although we must also highlight the possibility of a greater number of forest fires due to bad human practices and precisely at a time of maximum risk. Those that are to come. The 2026 eclipse is just the starting signal for a ‘trio of eclipses’ that can be seen from Spain. The specific agenda we have is the following: August 12, 2026: the great northern eclipse, at sunset, which is total. August 2, 2027: Just one year later, another total eclipse will cross the southern tip of Spain. It will be visible from Cádiz, Málaga, Ceuta and Melilla. Unlike the first, this one will be in the morning and will be one of the longest of the century, with a total that will exceed 4 and a half minutes in the Strait. January 26, 2028: an annular eclipse (where the Moon does not completely cover the Sun, leaving a bright circle) will cross the south of the peninsula, visible from areas such as Seville or Granada. In this way, the Government has the task of preparing for three different events in a range of three years that will attract a large number of national and international curious people. In Xataka | Between 2026 and 2028 Spain will become an eclipse paradise. And we have new maps to know where they will look best

They are the last hope of an ecosystem on the brink of collapse

by

Under the waters of the Mar Menor, a tiny army has just deployed on a pyramid of biodegradable clay bricks. There are 55,000 flat oysters —Ostrea edulis— born in a hatchery of the Spanish Institute of Oceanography (IEO-CSIC) and today converted into hope to filter and regenerate a system on the brink of collapse. The operation, carried out by the IEO team and the Association of Southeastern Naturalists (ANSE) with the logistical support of the WWF solar boat, It is the first experimental reef native oyster from the Mar Menor. A deep project. The project is called RemediOS-2, and it doesn’t come out of nowhere. Its first phase, RemediOS-1demonstrated in 2022 that it was possible to produce oyster seed from native specimens of the Mar Menor. In just four months, the IEO hatchery in Lo Pagán produced 60 million larvae from just 36 broodstock. Now, the second phase makes the leap to the open sea. The idea is simple, but ambitious: oysters are natural biofilters. A single oyster can filter five to ten liters of water a day, removing organic matter and nutrients. The researchers estimate that a well-established culture will retain up to 20% of the nitrogen that enters the lagoon each year, and that the entire oyster population would be able to filter the entire Mar Menor in just 23 days. But how does it work? The experimental reef is located near Isla del Barón, one of the most sensitive areas of the Mar Menor. There, 175 blocks of biodegradable clay designed by the company Oyster Heaven were anchored. Larvae settled on them, which now grow feeding on excess nutrients in the water. Each block functions as a “temporary home”: the material slowly degrades while the oysters attach themselves to the bottom and form their own natural reef. In total, the system occupies about 12 square meters of seabed, but represents a key experiment in ecological restoration. Scientific monitoring is carried out by ANSE under the direction of the IEO-CSIC. Technicians analyze the survival, growth and stress level of the oysters, in addition to measuring their sexual maturation and the accumulation of contaminants such as bacteria. E.coli or marine biotoxins. An extra help. To monitor this entire process they need even more hands. So the project counts too with technological support from the Polytechnic University of Cartagena (UPCT). Its researcher Francisco López Castejón used a remote underwater vehicle (ROV) to inspect the reef and see how this technology can monitor underwater habitats where diving is difficult. With science and technology working together underwater, the next question is inevitable. Why oysters in the Mar Menor? For decades, this sea has suffered from the accumulation of nitrates and phosphates from intensive agriculture. These nutrients feed an excess of phytoplankton that clouds the water and depletes oxygen, causing massive episodes of anoxia and death of fauna. The goal of RemediOS-2, in the words of the Department of the Environment of the Region of Murciais that the flat oyster acts as a natural regeneration tool. Its filtering helps reduce eutrophication and its shells, rich in calcium carbonate, contribute to carbon storage, an added benefit in the face of climate change. Beyond restoration. The project is also a test bed for a new blue economy. According to the Pleamar Program, The project aims to involve the local fishing sector, organize marine spaces for future restoration actions and demonstrate that regenerative aquaculture can be compatible with environmental recovery. The third phase of the project will include genetic studies to check whether local oysters are better adapted to climate change, with the aim of producing resistant “seeds” that can be reintroduced both into the lagoon and the Mediterranean. Forecasts. For now, oysters continue to grow under the gaze of researchers and underwater robots. The third part of RemediOS is already in planning. Perhaps these 55,000 oysters alone cannot save the Mar Menor, but they can demonstrate that environmental restoration can start with a mollusk, a handful of biodegradable bricks and a simple idea: let nature repair itself.

“Circular financing” between Nvidia and Openai can be the genius of the century … or collapse

by

Nvidia has announced A “strategic investment” of up to 100,000 million dollars in Openai. But it is an investment with trap: Openai will use that money to buy Nvidia chips. The semiconductor manufacturer thus becomes the financier of its own most important client. Why is it important. This maneuver dangerously reminds the “circular financing” schemes that characterized the end of the 2000 Puntocom bubble. Companies like Lucent, Nortel and Cisco financed operators as Global Crossing to buy them equipment. We are not the first to see this simile At this stage of AI. When the bubble exploded, both suppliers and customers sank into a spiral of debts and overcapacity. The agreement will allow OpenAI to build data centers with a joint capacity of 10 gigawatts, equivalent to about 10 nuclear reactors. Jensen Huang, CEO of Nvidia, has acknowledged that this represents between 4 and 5 million GPUS: “double those we distributed last year.” Brutal scale In figures. The numbers are astronomical. According to Huang himself in August, creating a 1 Gigavatio data center costs between 50,000 and 60,000 million dollars, of which about 35,000 million are destined for Nvidia chips. With that logic, the 10 projected gigawatts would cost more than 500,000 million dollars. The bags have reacted with euphoria: Nvidia shares rose almost 4%, adding 170,000 million dollars to their stock market capitalization. Jensen Huang Broza’s company is already 4.5 billion dollars of valuation. Yes, but. Parallelism with the ‘Puntocom’ bubble is disturbing. These same schemes of ‘Financing vendor‘We already saw them in the final stage of the 2000 technological bubble. They did not end well for any of the parties. The difference is that current numbers are much larger, even adjusting for inflation. The key is whether the productivity profits of the generative AI will compensate for the spent money. Between bambalins. The agreement explains the current situation in the AI ​​ecosystem: OpenAi desperately needs computing capacity to maintain its competitive advantage over the 700 million weekly users of their products. But infrastructure costs are so high that it needs constant external financing. Nvidia, on the other hand, seeks to ensure the future demand of its most advanced chips. The agreement guarantees mass orders while consolidating its dominant position against competitors such as AMD and Intel. “It is a closed cycle: Nvidia gives OpenAi money, and OpenAi uses it to buy Nvidia products,” Summary Summary Javier Pastor. The threat. Anti -Ponopoopoly experts are already arched eyebrows. Andre Barlow, a lawyer specialized in competition, explained to Reuters that “the agreement could change the economic incentives of NVIDIA and OpenAI, potentially blocking the Nvidia chips monopoly with OpenAi software leadership.” The structure creates extra barriers so that competitors such as AMD in OpenAi chips or rivals in AI models can climb their operations. They paint basts. In perspective. The story is full of similar schemes that ended badly. Global Crossing, the telecommunications operator that broke in 2002it was funded precisely by the same suppliers that sold equipment. When it was discovered that the real demand was much lower than the projected, both Global Crossing and its financiers lost thousands. The key question is whether the demand for AI services will be sufficient to justify this billionaire investment, or if we are faced with the recreation of the same speculative pattern with even more exorbitant figures. As Stacy Rasgon concludesBernstein analyst: “On the one hand, Openai helps meet very ambitious infrastructure objectives. On the other hand, it will further feed concerns about ‘circular’ financing.” Outstanding image | In Xataka | Openai estimates that it will enter 200,000 million dollars in 2030. The figure, like everything in OpenAi, is extremely ambitious

of inflationary threat to historical price collapse

For months, the world feared a reissue of The 2007-08 food crisisWhen the rice exceeded $ 1,000 per ton and caused disturbances from Haiti to Bangladesh. At the beginning of 2024, Thai rice for 5% – referring in Asia— ton $ 650 per tonits maximum in ten years, promoted by the child, protectionism and panic purchases. And yet, in August of this year the opposite has happened: the international price slid towards minimums, driven by historical crops and yields that do not stop improving. It is the silent victory of productivity: more rice with almost the same land. International prices in free fall. In recent months, rice has been drastically cheaper. According to Financial Times5% Thai party white rice is negotiated at $ 372.5 per ton, its lowest level in eight years, after a 26% decrease since the end of last year. The United Nations Food and Agriculture Organization (FAO) Confirm the trend: Its global rice price index (FARPI) was reduced by 13% so far this year, and in July another 1.8% monthly fell, standing 22% below the previous year. Abundant supply, absent demand. In an extensive report by the Financial Times They have pointed out That, on the side of the offer, India – the largest exporter – in September last year the restrictions on external sales, while reached the market with a record harvest in 2023/24 and public stocks that reached 60 million tons in May, up to 15 million more than the average of recent years. Part of those surpluses even went to ethanol to release space before the new campaign. In addition, good campaigns were added in Thailand and Vietnam, which brought world production to a record level. On the side of the demand, Indonesia advanced purchases last year and withdrew from the market, while the Philippines forbade imports until October to protect its main harvest. “It’s that simple: there are no buyers,” summarized Samarndu Mohanty, director of the Center for Studies of Agriculture and Sustainable Development of the State Agricultural University of Telangana, cited by FT. The result is easy to define: there are plenty of stocks and lack of buyers, and, therefore, prices collapse. An exception: Japan. While global prices collapse, Japan suffers the opposite scenario. According to Bloombergthe country lives an extreme heat summer and drought in key producing regions such as Tohoku and Hokuriku. Kazunuki Ohizumi, Professor Emeritus at the University of Miyagi, has anticipated the environment: “Ris -of yields and distribution volumes will almost certainly fall.” To contain the crisis, the Japanese government released hundreds of thousands of tons of reserves and allowed to expand the culture surface. However, the measures were insufficient. In May of this year, As my partner has pointed out for XatakaJapan took an unprecedented step in 25 years: import rice from South Korea. Shortly after, the Aeon chain announced the sale of American rice Calrose, 10% cheaper than El Nacional. Social and political pressure has been enormous: surveys show a collapse in the approval of Prime Minister Shigeru Ihiba, and the controversy was fueled after unfortunate statements of the Minister of Agriculture. In addition, the Japanese country maintains a strict protectionist policy: only 770,000 tons annually enter tariff, and outside that fee the rate amounts to 341 yen/kg (about 2.30 dollars). Even in a context of world abundance, its consumers paid up to 50% more than a year earlier, According to Bloomberg. The productivity lever. The global price collapse has a historical background. According to Javier Blas in his column for Bloombergrice yields have gone from 2.4 t/ha in 1975 to about 4.7 t/ha in 2025, thanks to the massive use of fertilizers, pesticides, irrigation and improved seeds. The global rice surface has barely varied since the 80s, but the production has doubled, until reaching an expected record harvest of 541 million tons in 2025/26, According to FAO. The “monsoon proof” resilience. In particular, India has become an example of resilience. As Financial Times explained, The country has almost universal irrigation systems in the main rice regions, guaranteed minimum prices and state bonuses that protect farmers. This allows you to hold record crops even with erratic monsoons. The minimum guaranteed prices (MSP) and state bonuses ensure a mattress against international volatility. In addition, farmers buy new seeds every season, which increases yields and expands the surface. In this way, the result has been a leftover offer that New Delhi channels both the domestic and international market, and even industrial uses such as ethanol. Winners and losers. For consumers and importing countries, decrease is good news: less inflationary pressure in the basic basket. For producers, especially in Asia, it is the opposite: with increasingly expensive supplies and depressed international prices, margins narrow dangerously. Rice also becomes a stability factor or political instability. Blas Remember that in Asiawhere rice is central in the diet, a price rebound can overthrow governments. Japan is now experiencing it: the internal basis has tensioned to the administration of ISHIBA. What to wait for the future? The base scenario indicates that prices will remain weak. Analysts consulted by the Financial Times They foresee a possible additional drop of 10% if shocks do not occur as a new extreme climate episode or commercial restrictions. Blas in your column Calculate that world rice production of 2025-26 will be the largest in history, which will maintain the bearish pressure. But Japan remembers that climate change can decoupling internal markets from the global trend: a summer too hot is enough to transform world abundance into a domestic crisis. The grain that measures stability. Rice is, perhaps like no other food, the measure of our ability to feed the world. Today their prices sink because humanity has learned to produce more with less land, not because the weather has given a permanent truce. For millions of families, that means a more affordable table; For millions of farmers, the threat of an income in fall. The challenge is clear: to extend the benefits of productivity without leaving behind … Read more
