Now we are discovering reality

by

Passwords are a gain. Remembering them is an almost impossible mission, creating safe versions makes us entering several special symbols, and to top it off, we see leaks of these data from time to time. Therefore, the different technology companies seek a definitive solution to end them. One of the alternatives that is gaining more popularity is apparently simple and elegant: Enter the email or phone and receive a single -use code. But it is not completely safe. Large companies adopt the ‘Magic Link’. The login without password has been adopted by different companies such as Microsoft. The promise is clear: eliminate friction and risk of reused passwords in different services. However, what seems like an ingenious solution is becoming a security nightmare, a system that, in certain scenarios, can be even worse than the denoted passwords, as the expert Daniel Huang recognizes. And it is not a theoretical threat; It is already actively exploited. Introducing the email is the first step of deception. A priori seems like a simple and harmless system, and as users we are getting used to that If we receive a code you have to use it. But where? This is where a cyber of the intention finds a new reef for attacks of Phishing improperly effective. It all starts receiving an email or a SMS of Phishing Very convincing. It can be an irresistible offer or a security notice that attracts a lot of attention that is accompanied by access to a web page, which is a perfect clone to the original through which they are being passed in the SMS. This is where they ask that the phone or email be introduced, and it only remains to wait for the next step. Behind the screen is where the attacker is located. Where it is not seen, the hacker introduces the email or phone on the legitimate website, which makes the real service Send a six -digit code completely valid to the input tray or the mobile messages section. And here it is where the false website Ask that the verification code that has been received be introduced, taking advantage of the previous times where doing this had happened absolutely nothing. Here the damage is done. The code is received by the attacker who will use it on the Real website, starting session and changing all the login information as email or telephone to seize an account. And defense systems serve as little, since a password manager cannot self -model anything and as the code is legitimate and sent from a real service spam filters They will not jump either. A security problem that has already been exploited. This does not remain alone in theory, but has been put into practice. One of the most notorious examples is Microsoft’s login system for Minecraft accounts, as shown In the company forums either In Reddit threads. Many players point to how they lost access to the account of the morning due to this type of fraud. The employer was always the same: they received an email with some excuse about their Mojang account and following the steps delivered the hint access code in the silver tray. Classic access code or passwords. This is the great decision that must now be made by large companies. And one of the solutions that would guarantee have a safe password is A good password manager. In the event that it is of quality, access credentials are linked to a specific URL, and that is why if an illegitimate website will be accessed, the web address will not coincide and will not be self -realized. The best defense is common sense. With both access systems, 100% security is not achieved. In the past we have seen Very important password leaks, Like hackers They published very extensive files with credentialsthe robbery scams that have been reported either the strategies that are followed To make the robbery of credentials, Even in Chrome. That is why, as security councils, the most important thing is Check web addresses and distrust everything that can get out of the normal.

Notifications killed our concentration. Now they are kidnapping our mobiles

by

For more than and a half, the applications of our mobiles They are perfect machines to suck time that hook us with techniques such as Scroll infinite. We have ended with A generation that lives decentralized Even when we do not receive relevant notifications of work, school, friends or family. And that is precisely one of the big problems we face today: an enormous amount of useless, irrelevant notifications and in many absurd cases that kidnap our mobile. What’s happening. It is increasingly common to receive unwanted notifications on our mobile. And the pity is that, in the face of email, there is no Spam filter. The problem is that there are applications of banks, neoboncos, transport, electronic commerce, food at home or second -hand sale, for putting examples, which do not stop riding advertising notifications without relation to the reason why they are installed. The problem. The engineer and hacker Jaime Gómez-Obregón told Recently the behavior of some of the most popular applications you had installed on your iPhone. Blablacar sent him promotions notifications, despite having deactivated trade communications. Without authorizing offers, they arrived from Cabify, Uber or N26. His followers told him that the same thing happens with Revolution, Wallapop and Banks Applications such as BBVA. A server can talk about your experience with OpenBank: receive more promotional notifications than bizums, payments or transfers, despite having requested that they do not send me more advertising to your customer service by phone. When deactivating notifications as a final measure is dangerous. We talk about kidnapping because, although both in iOS and Android we can deactivate the notifications of the applications we choose, the important thing is what we lose in doing so. If I am waiting for the Uber driver to arrive, I can’t deactivate his applications. If I am waiting for a possible Wallapop buyer to respond to which I am interested in selling something quickly, I cannot deactivate notifications. The same happens if I am waiting for the notification of my payroll or a transfer in the bank or the message of a Blablacar driver for a journey that I cannot do with any other means of transport, and that of not seeing it, I risk not being able to reach a destination. In the end, it is similar to deactivating notifications in a WhatsApp group where a lot about important things are discussed. With the difference of our contacts they know that they can talk to us in private to let us know that something relevant is cooked and we have not heard. In Wallapop you can individually deactivate promotional notices. Without losing user messages notifications. The solution we expect and does not arrive (with exceptions). The rain of promotional notifications is easily solved, if applications developers want. In the APP notification settings it can be offered separately stop receiving notifications of direct messages, a public mention, or advertising. The problem of many applications is that everything gets into a sack, and you cannot deactivate only advertising, or not in an obvious way (without having to send mails, make calls, etc. In this sense, my partner Javier Lacort complained on Twitter a long time ago Wallapop behavior. Without defining the type of promotional message he was learning, Javier learned thanks to The response of a follower That Wallapop is one of the companies that incur this good proposed practice: it lets you deactivate the promotions separately. The general reality? Insufferable. Google is clear that it is wrong. Apple not so much. On its documentation website on developers, Google makes clear “When not using a notification“The reality is that with their services they send similar messages. Apple prohibited notifications with ads until 2020. Changed the rulesand now Send notifications promoting savings in tickets to see ‘F1’ In the portfolio application. Even so, in the Standard 4.5.4 They modified continue to mention the following: Push notifications should not be used for promotional or direct marketing purposes, unless customers have explicitly accepted to receive them through a consent text shown in the user interface of your application. This is how Google explains to developers the bad practices on promotional notifications. And when requesting the notification permit, Wallapop, for example, does not inform in any way that it will later send promotional messages (although in your case we can deactivate them separately). When asking for notifications, applications do not report that they can contain promotional content, as Apple establishes in their terms. In full era of AI, both Google and Apple could implement filters to detect notifications not requested by the user and whose relevance is very questionable. They could also provide the system of functions to filter keywords or list of words allowed and prohibited according to each application. It is just what he does Bullkill Notification Manager on Androidand its users mention being Very happy Just to combat promotions. Android offers control of notifications by category, but, again, it is something that the developer has to activate so that the user can choose what type of messages he wants according to the app. Image | Generated with chatgpt and Jonas Leupe in Unspash In Xataka | I have been following the advice of those who point to the mobile and its notifications such as the tobacco of the 21st century

In silence, Morocco is becoming a peculiar economic power: the "Türkiye" of the teeth

by

In recent years, Morocco is becoming a proper name in several sectors. His relevance in the geopolitical panorama, economic and energetic It is now out of any doubt, but also wants to do A elbow hole in the tourism sector. Rather, to bites, since a trend that has taken traction between tourists is to travel to Morocco to visit the country and return home with a new mouth. And has made Spanish dentists raise an eyebrow. All inclusive tooth tourism. When we travel, many opt for complete packages that guide the experience. What is happening in countries like Morocco is that travel agencies and dental clinics themselves offer all inclusive packages that combine everything we need to enjoy both the country and extra services. These packages include flights, cultural experiences and, to finish off, Dental treatment. If you have ever had to undergo some mouth treatment, you will know that they have been between previous analysis, the procedure itself and the reviews, but these clinics highlight their ability to perform the treatment in a few days. The goal is to arrive, receive medical attention, do tourism and return home. In Xataka The Canary Islands will tend an underwater cable to Morocco. If Morocco decides to extend it, Spain will have a problem Usual treatments. They make it clear that they have 3D scanners, CAD/CAM technology (scanning tools, virtual design and automated manufacturing thanks to 3D printers) and the specialized personnel necessary to carry out the procedures. Which is it? Well, some quite helped and “from here I catch you, here I kill you”, and others somewhat more complex: Aesthetic veneers. Dental implants. Crowns and complete reconstructions. Whitening Orthodontics. {“videoid”: “x8px49v”, “Autoplay”: True, “Title”: “Antibiotics are ceasing to be effective and the problem is superbacteria”, “Tag”: “Webedia-prod”, “Duration”: “327”} Price and record time. And, apart from the times, if you have had to touch your mouth you will know perfectly what it costs. Prices vary depending on what treatment we do, but the most common seems to be the veneers. They are what we can see with the naked eye in a smile and may, influenced by the media pressure and beauty standards With perfect smiles On television, Tiktok and InstagramIt is also the most popular. It is estimated that the prices of this procedure in Morocco are between 70 and 80% cheaper than in countries such as the United States or the United Kingdom. It all depends on the material (composite or porcelain veneers can be made, for example), but there are also couple offers with resin veneers composed of 1,250 euros per person … or 2,000 euros for two people. Not only Morocco. It must be said that Morocco It is not the only destination that we can see publicized in networks or the web if we want to make any touch -up. Türkiye (also popular for other aesthetic procedures) and Albania have been one of the Main destinations for dental tourism. The veneers, again, are the protagonists, with cheaper prices than in other markets. The arguments are exactly the same as we see in the case of Morocco: “A recklessness “. The big question is what Spanish dentists think. And the answer is evident: not very well. The General Council of Dentists published on July 1 a release On this type of tourism, recommending that we be cautious about this type of advertising. The main argument that wields against these dental treatments Express is that the necessary time is not dedicated to it. In Xataka There are young Spaniards earning $ 10,000 a month in the Australian coal mines. But everything that shines is not gold All treatment entails risks, and if the oral state of each person is not correctly evaluated, short and long -term inconveniences, such as dental sensitivity, gum problems and even dental loss may arise. Traveling to another country to undergo a health process is not an adventure, it is a recklessness, ”says Oscar Castro, president of the Council. In addition, it ensures that leisure and health cannot be mixed and that, if something happens with the pieces that the patient has put in Morocco, who is responsible.

The US wants China to become addicted to Nvidia chips. His problem is that his greatest rival is not for the work

by

The administration led by Donald Trump has realized that her predecessor and herself have made a very serious mistake. SANCTION PACKAGES that have deployed during the last three years To prevent China from doing with the most advanced semiconductor manufacturing equipment, and also with avant -garde chips for artificial intelligence (AI), have forced the Government of Xi Jinping to become independent of foreign technologies. The Chinese industry of the integrated circuits has advanced a lot during the last five years, and will surely continue to do so. It is very likely that in 2026 Chinese manufacturers have their own extreme ultraviolet lithography equipment (UVE). And currently Huawei, Moore Threads and other Chinese companies have GPU for some scenarios They compete with the Nvidia and AMD chips. The independence of the Chinese semiconductor industry is underway. The best output given this juncture for the US is none other than to deliver to China in a controlled way advanced chips for AI, but less powerful than the most capable that design Nvidia, AMD or brains. In this way this Asian country may relax a bit its ambition for development and independence. This is exactly what the Trump administration is doing by allowing Nvidia to give back to its Chinese clients Your GPU for IA H20as Chris Miller holdsthe author of ‘The chips war’in his Newsletter. China is getting out of Nvidia The future of Nvidia in China is largely in the hands of the administration of the cyberspace of China, known as CAC for its English denomination (Cyberspace Administration of China). This institution is the main Internet regulatory body in China and is thoroughly investigating NVIDIA H20 GPU Because it suspects that this chip could incorporate a back door of difficult location by Chinese experts. If so, the possibility of China to use this GPU could be possible. David reber Jr., Nvidia Security Director, published last week An article in the blog of this company entitled “There are no rear doors in the Nvidia chips. There are no deactivation switches. There are no spy software” in an obvious attempt to defend the company’s reputation and appease the growing distrust to which he faces in China. There is a lot at stake. If the final resolution of the CAC turns out to be unfavorable with all probability NVIDIA will lose a good part of the income currently obtained in this country. The Chinese government is urging Chinese companies that are dedicated to the development of large models of the use in their Chinese chip servers However, this is not all. Whatever the CAC verdict is a fact that the Chinese government He is urging Chinese companies that are dedicated to the development of large models of AI to use in their servers integrated circuits of Chinese origin. In this scenario their best bazas are now Huawei and Moore Threads. The first of these companies has lists its own GPU for iathe chips ascend AI, for more than five years. During this period of time it has been refining them and increasing their abilities with the purpose of matching or even overcoming the performance of the chips A100 and H100 of Nvidia. His most ambitious proposal right now is the chip Ascend 910dwhich seeks to overcome the performance of the H100 GPU. However, this Chinese company has also recently presented its chip Ascend 920a solution that is clearly destined to occupy in the Chinese market The H20 GPU space. This proposal will enter large -scale production during the second half of 2025 using 6 NM integration technology that have presumably developed elbow with Huawei elbow and SMIC. On the other hand, Moore Threads He has developed several GPU for AI applications that, on paper, rivaize some of the advanced solutions that have placed in the Nvidia, AMD or Huawei market. The MTT S4000 and MTT S3000 cards are its most interesting proposals right now, although, curiously, in its porpholio the MTT S80 card, a proposal for games and content creation that, according to Moore Threads itself, has a 14.4 TFLOPS calculation capacity also appears in Floating Coma operations of simple precision. It doesn’t impress, but it’s not bad at all.

The disaster was such that for 40 years it was silenced

by

Spy stories And authentic paws weather will be many, and we are sure that we do not know a good number of them. However, few can approach what happened in one of the most famous and majestic mountains on our planet. There a peculiar excursion took place several decades. Everything that could go wrong, went worse. In fact, Plutonium is still there. For those who do not know what we are talking about, NANDA DEVI It is the Second High Mountain in India and the twentieth third in the world, with a height of 7,816 meters. It is not just any peak, since it has a deep cultural and spiritual meaning, especially in the Uttarakhand region, where it is considered sacred. The area surrounding Nanda Devi has been recognized for its unique biodiversity as a World Heritage by UNESCO. The park protects a variety of species and is an example of the wealth of Himalayas. In addition to its natural and cultural importance, the enclave has been a symbol of adventure and mountaineering. Since his first ascent in 1936, it is a challenge for mountaineers around the world. On the other hand, its ecological fragility has restricted the region to protect its environment. This last point, as we will see next, was not always the case. Hopefully nature is not vindictive … The first nuclear test Not far from the mountain, in October 1964, the First nuclear test in China In the immediate vicinity of Lap Nur Lake, a region that bordered the Kuruk-Tagh mountains. This test was followed by several tens and put on the US on alert. The CIA investigated how far the Chinese were advancing. Two years before, China had defeated India’s army and those first evidence were an example of power and strength. The American agency concluded that they were staying behind in the nuclear race in a delicate context such as the cold war. And not only USA, India felt inferior after its border defeat. The alliance between the two countries soon arrived. What did they do? In an era where there was no satellite espionage technology like the current one, both nations signed A secret pact to combine efforts and spy on Asians. As? Literally, sending secret agents to the field “battle”. In other words, sending spies to the confines of the world, to some of the most imposing mountains on the planet where Chinese nuclear tests were being carried out. If the idea seems somewhat movie, it is because it is. The proposal of both nations consisted of using some of the mountains of India from which to see what they were doing from the Chinese side. It may seem naif, or even innocent, that the espionage agencies of both countries watched with good guy watch another nation thousands of kilometers for the simple fact of being in one of the “peaks” of the planet, but history shows that it was so, and In 1965 the “Master” plan was given green light. The CIA begins to search and recruit the spies that would bring the plan to fruition. One of them was Robert SchallerMedicine student in Seattle to which a proposal worthy of a Hollywood film is sent. They needed A doctor in Himalayas With experience in electronics and mountaineering, a combination of requirements that took them to the student, the first on the list that was filled. When the team had formed, intense training in a secret enclave began for months. Together with Schaller there were a large number of celebrities who were going to become citizen spies like him. For example, the famous Yosemite climber, Tom Frost, or the one who was going to be the captain of the expedition and famous mountaineer for the expeditions to Everest, Mohan Singh Kohli. Others were not so well known, but they were elites, researchers or teachers whose knowledge in nuclear technology put them at the service of the secret alliance between the US and India. We are not talking about normal training, of course. After the first tests the level was raised for several months with jumps from a helicopter, or demolishing objectives with explosivesthey even managed Experimental Atomic Energy Hardware that had been developed exclusively for the mission. Last and not least, the team had to prepare for the ascent crawling next to the mission material by the Alaska cliffs. A year after the first Chinese nuclear test, this team of intrepid citizens turned to spies is ready. All are found in the sanctuary, a kind of natural strength of the summits that surround the Nanda Devi, the final objective. A detail nothing trivial: until then, only six people had managed to make a summit in the peak, and of those six, only three had managed to go down alive. Be that as it may, the plan continued with an unexpected partner. It had not been revealed until then, but the team had to ascend with an extremely heavy surveillance package, a monitoring system that required atomic energy to work. We talk about An artifact containing a 19C Snap generator which converted the heat of the plutonium into electricity, which subsequently allowed monitoring possible nuclear activity (in this case, of China). Climbing with plutonium If up a mountain with the right material is a complicated activity, with an atomic artifact of extremely heavy motorization was a matter of faith. In addition, we talk about types that came from very different fields, many very poorly prepared for such a physical mission, no matter how much they were training for months. Therefore, during the day the artifact made their lives impossible and advanced up the ramps as turtles. However, at night the thing changed, and The device was able to provide extra heat to spies. And, inside the generator, there was enough plutonium to feed the surveillance system for more than a thousand years, which for practical purposes would mean that both USA and India could monitor the Chinese for centuries.

Silicon Valley prefers to buy herself rather than invest in the future

by

Great American technology They swim in money in cash but to a large extent they are preferring to spend it repurchase their own actions rather than invest. How the mechanism works. A shares is simple: the company uses its cash to buy its own market shares and withdraws them. If a company has 1,000 million shares and repurchase 100 million, there are 900 million. The trick is in arithmetic. If the benefits are the same but there are fewer actions, the benefit per action Go up. A company that earned 10,000 million with 1,000 million shares showed 10 dollars of benefit per share. With 900 million shows $ 11.11. The metric goes up even if the company has not improved at all. Executives charge on actions on actions. Your compensation increases. The funds see the value of their portfolios without waiting for years to mature real investments. The company avoids the risk of investing in projects that can fail .. It is capitalism without capitalism: financial returns without real value creation. Why is it important. The further reason towards the tendency to an increasing repurchase of actions can be inferred: fear. The American political climate has become especially complex for large industrial investments. Bureaucracy, regulations. It is safer to return money to shareholders than to risk building something real. Meta tried to expand his campus in Menlo Park next to a plan to create affordable homes and He crashed into years of bureaucracy. The project has been in pause for some time. Amazon He left his plan to open a second headquarters in New York for the strong political protests that unleashed his announcement. Intel has been trying to open factories. And seeing how China ends them in a couple of years. The financial refuge. Act repurchases have become the bunker where technological ones hide their cash. In 2025 They will exceed the billion dollarshistorical record. Warren Buffett himself, nothing suspicious of anti -capitalist, has once said that Many repurchases are “stupid”. Explained that they benefit more than paid executives in Stock Options (Actions options) than long -term shareholders. The context. The repurchases They were illegal in the United States until 1982when under the presidency of Ronald Reagan they were authorized. Until then they considered a form of market manipulation. They are now the main way to give back shareholders. They exceed traditional dividends. A Study of the Roosevelt Institute of 2018 He showed that S&P 500 companies then spent 94% of their benefits on repurchases and dividends, leaving barely margin for productive investment. And now what. In the United States, some Democratic senators proposed a couple of years ago a 4% tax on repurchase programs to discourage them. What came from the hand of Biden It was 1% that has not had a great effect. For Europe, which depends technologically on the United States, this trend is worrying. If Silicon Valley prefers financial engineering to real, vulnerability against Chinese advance increases. In Xataka | The agreement with the US seemed to pave the way to Nvidia in China.

The most self -sufficient countries on the planet at the food level, gathered in a surprising graphic

by

Humanity has eaten what it played For thousands of years. With globalizationhe has started eating what he wants and that, together with the population increase, It has consequences. Not being able to meet the demand of some foods, Import is a necessity. But it turns out that there is a unique country in the world, a completely self -sufficient one if we talk about food. Guyana The All-Star of Self-sufficiency. In the upper graph, prepared by Visual Capitalistwe can see the 50 most self -sufficient countries in the world at the food level. It reflects seven food groups: Fruit. Vegetables. Legumes. Starchy foods such as flours or rice. Meat. Fish. Dairy. And the only country that not only complies, but exceeds the production of what its population of each of these groups needs is Guyana. It is a small country of about 815,000 inhabitants located in northern South America that has shot your GDP These last years. Partly, thanks to discovery Of great oil reserves in 2015, but before that boom, their agricultural and mining industry were the ones that pulled the car. Closing the podium. So much that it is, as we say, the only one that produces its own food in all groups, highlighting in one that does not usually highlight: starchy foods. Closing the podium, we must look at Asia. Vietnam and China are two other countries that meet in six of the seven groups. The common strong point is the production of meat and fish (Meritory in the case of China, but At the expense of half -world folders). The weak is that of dairy products. It is common in Asia, with cases as dramatic as Indonesia, Thailand, Tonga, Laos or Philippines, which satisfy 0% of their dairy consumption with the national product. To the tail … On the other side of the balance we have Armenia, Thailand and Greece. The three countries are in the group of those that meet in the production of four categories (where the vast majority of countries are found), but with low percentages in general in almost all groups and a total dependence on dairy and vegetables in the case of Thailand, starchy and, curiously, fish in the case of Greece and legumes and fish in the case of Armenia. Europe and the fruits that come through those who come out. Taking an eye on the panorama of the member countries of the European Union (Greece is an example), we see that some falter, others stand out. And vice versa. The north, for example, does not get along with the Fruit culturesomething that does stand out in the countries of the South. The key in this case is the Single market Agricultural that allows food products to circulate freely between member countries, without regulatory tariffs or barriers. More than 70% of EU’s food products is carried out between member countries, being something that ensures balance and supply even in cases of local productive problems.

Despite drought and climate change, Andalusia is today greener than in the 90s. It is not as positive as it seems

by

A few months ago we count that Spain was getting greener. We did not refer to renewablesbut to the spectacular effects of a spring Exceptionally rainy that He moved the ghosts of the past. The problem was what would happen after those rains and If the drought would call back to the door. Now we are in a totally different scenario: heat waves and, Like every summer of recent years, The fight against fires. In spite of everything, and to climate change, NASA shows that Andalusia is today more “green” than in the 90s. And it is not to be too excited. Short. Spain is a country with drastic microclimal changes on which the flora depends. In the south of the peninsula, they are the Mediterranean forests Those who occupy 26% of Andalusia and the conditions of much of the soil have made pines and holm oaks are the dominant speciesS, since they adapt well to areas without plant cover. Andalusia is a good study scenario because climate change clearly draws its effects, such as upward temperature, decline rains and increased aridity. And, as we see in Physa team of researchers has published in Ecological Indicators How these forests have responded during the last 30 years. Tools. For the analysis, the researchers used more than 5,000 satellite images captured between 1994 and 2021 obtained Thanks to Landsat 5 and Landsat 7NASA. In total, they analyzed 2,358 plots that compared with data from Google Earth Engine and created an “greenery” index measured by Ndvi. They are the acronym of ‘Standardized Difference Vegetation Index ”, a way of quantifying, through satellite images or remote sensors, how much living vegetation there is in an area. In short, it is something that indicates the amount and vigor of the vegetation, being a tool widely used in studies of agriculture, natural resources management or those associated with climate change. Black squares represent 2,358 farms analyzed. In the most dependent areas of agriculture, the effects are much more limited What do we see. In general, except red eucalyptus, all species have shown an increase in this NDVI value, something that points to sustained revergeration. In trees such as holm oaks, cork oaks and pines, the maximum moment of activity is concentrated in the soft winter months, falling in the summers. And the chestnut, which is the only deciduous species of the study, operates on the contrary. The Effects of climate change And aridity have a decisive role in these cycles, extending the activity period of the Carrasco pine and the resin in the driest places and shortening that of other pine species, such as the wild, and that of the wild olive tree. Between 1994 and 2005, the growth of these species was evident, and followed its course from 2005 to 2021, although at a more moderate speed. ¿Because? The result is that, the green territory is now greener and the conclusion is that many species have maintained or increased its green coverage. There are several explanations, and very diverse. Carrasco or Encina pine are designed to support heat and droughtwhich allows them to remain active when other species lower the activity. Here the policies of natural reforestation and regeneration have played a role, as well as global factors such as the increase in Atmospheric co₂ that would act as fertilizer. There are also factors directly related to human activity, such as a progressive abandonment of farmland in certain areas that has favored the natural regeneration of the forest, as well as changes in land use, such as the decrease in livestock pressure that reduces the degradation of the undergrowth. We have also influenced the contrary, as with a cork oak, which we extract cork periodically, limiting the regeneration of the tree. Nuances. The study is very useful to see the current situation of the Andalusian Mediterranean forest, but also to observe which are the most resilient species and those that best adapt to changing conditions and a rampant aridity. And the conclusion of the study is that things are not going well, but due to that resilience of some species and, despite the continuous increase in annual average temperatures, most species did not demonstrate a relationship between phenological metrics and that temperature increase. And, perhaps, the most important thing is that the greenest does not equals a healthier vegetation, since various factors (natural and human) intervene and we see that this revergence is nothing uniform, with a south and this drier in which the vegetation is hardly growing. But well, as researchers point out, see what species are more resistant and adapt better is something that allows you to find the best options for adequate reforestation policies, Not how we are doing in many places in Europe. Before we talked about that rainy spring that moved the ghost of drought and that summer was returning to reality. And the Recent restrictions in Galicia They are a sad sign of this.

France and Morocco have allied to flood Europe with green ammonia. And compete directly with Spain

by

In December 2022, in full energy crisis and with the intention of stop depending on gas and oil from Russia, Spain, Portugal and France joined To define the H2Med green hydrogen corridor. The idea was to start producing green hydrogen for electricity generation, something that Spain can contribute thanks to its reserves and Great surplus of renewable. In April 2024, Europe approved the two axes planned in Spainbut a few months later, France reached a parallel agreement with Morocco. This is the Chbika project, and is as ambitious as controversial. Chbika. Europa presumes being a Power in renewablessomething that has been revealed in recent months, but also wants import a huge amount of energy directly from Africa. According to Europe, it is “essential to meet the objectives of the European green pact And to reinforce energy security ”, and within these agreements is the signed between France and Morocco. In October 2024, taking advantage of the visit of the French president Emmanuel Macron to Morocco, and with the presence of King Mohammed VI, an ambitious plan for the industrial production of green hydrogen and ammonia was signed. Goals. This project is driven For a European consortium formed by TE H2, a Joint-Venture of the French groups Total Energies and Eren, but also with the Danes Copenhagen Infrastructure Partners and AP Moller Capital. Their goals are: Build wind and solar infrastructure on land with 1 GW capacity. Green hydrogen production using the electrolysis technique thanks to Desalinated seawater. Use hydrogen to get 200,000 tons of annual green ammonia, mainly for the European market. Green ammonia. Apart from green hydrogen, which is used to generate electricity, the Green ammonia It is a compound formed by nitrogen and hydrogen that is achieved by electrolysis that uses renewable energies. The traditional process to achieve ammonia implies natural gas, so the use of renewables in the process makes it a process without CO₂ emissions. The main use of ammonia is as agricultural fertilizer, but it can also be used as a hydrogen bearer. It has a high energy density and is easier to transport than hydrogen (not needing cooling as extreme as H2), which makes it an energy vector to export hydrogen at long distances. In search of treasure. This agreement seeks not only to strengthen cooperation between Europe and Africa in energy matters, but also consolidates the position of Morocco as a key supplier of clean energy to the European Union. And it is aligned with the Repowereu program that intends to import 10 million tons of green hydrogen before 2030. Although the pact was signed in autumn last year, a few weeks ago the confirmation of land rights in which the plant will be built and advances in technical and legal agreements that settle the bases of the operations that will come below were made. Controversy. Now, the Chbika project is not exempt from controversy. On the one hand, it has been indicated as a Moroccan maneuver to strengthen its position in green hydrogen within Europe, competing directly against Spain. On the other hand, part of the territory destined for the project, in the Guelmim-Oed Noun region, is considered by agencies such as the UN as border or superimposed with areas of the Western Saharaoccupied by Morocco. Activist organizations They denounce that many of these energy projects in Morocco are building On occupied Saharawi territoriesand what is it about *Greenwashing operations* Through clean energy while they continue to oppress the Saharawi people. Spanish plans. Meanwhile … What does Spain do? Well, some of its companies, such as acting or cepsa, They have also signed with Morocco. The objective of the African country is that renewables represent 52% of their installed capacity for 2030 and green hydrogen is a means to achieve it. And, for this, a Moroccan government committee selected five consortiums to develop six green hydrogen projects with the intention of producing ammonia, steel and industrial fuel. Problem? Apart from the competition with Spanish projects, they will be developed in the aforementioned Guelmim-Oed Noun, as well as in Dakhla-Rio de Oro and LaAyoune-Sakia el Hamra, also occupied territories, which can increase diplomatic tensions With Spain and the Sahara.
