cities

While Europe looks at Ukraine, the US has sounded the alarms for Spain on a closer front: losing two autonomous cities

by

In July 2002, a handful of Moroccan soldiers landed on the islet of Perejil and raised a Moroccan flag there. The Spanish response came days later with a military operation so rapid and measured that it ended up becoming one of the diplomatic-military episodes strangest of the recent Mediterranean. What worries Spain. While Europe concentrates much of its military attention in Ukraine and the eastern flank of NATO, a much closer concern is growing in Spain: the south of the Strait. The problem is not just Morocco or the military balance in the Maghreb, but the change in the United States’ attitude toward the region. The appearance in Washington of official documents that describe Ceuta and Melilla like cities “under Spanish administration” in Moroccan territory has generated unprecedented alarm because it breaks a historical diplomatic taboo. For decades, the sovereignty of both cities was considered out of the question for Western allies. Now some American political sectors are beginning to treat her as an open dispute susceptible to future negotiation. US pressure. Spanish concern does not arise solely from a parliamentary report, but from the political context that surrounds it. Republican congressman Mario Diaz-Balartclose to Marco Rubio’s entourage and aligned with positions very favorable to Rabat, has not only publicly defended that Ceuta and Melilla are “in Moroccan territory”, but that the own report encourages the State Department to promote diplomatic talks about their status. All this coincides with the deterioration of the relationship between Donald Trump and the Spanish Government for military spendingNATO and the disagreements over Iran. In certain strategic Spanish sectors, the feeling is beginning to spread that Washington increasingly considers most useful to Morocco as a regional and less essential partner to Spain within its Mediterranean architecture. Morocco and the new balance. The most profound change may be occurring on the other side of the Strait. Morocco has been accelerating for years its military modernization through agreements with the United States, Israel, Türkiye and France, while also promoting its own arms industry. Since 2021, industrial projects linked to drones, weapons and advanced military production have multiplied. At the same time, Rabat has consolidated his diplomatic position in Washington after the American recognition of Western Sahara. For many Spanish analysts, the problem is no longer just migratory pressure or specific border crises, but the emergence of a regional power much more militarily connected to the West and increasingly secure in its strategic position. Spain is left out. The other big concern is that Spain seems have been left out of the new network of military alliances in the Maghreb. Italy has become the main strategic partner of Algeria in the Mediterranean, expanding defense agreements, industrial cooperation and military coordination with one of the most powerful armies in Africa. Morocco, meanwhile, close ties with Washington, Paris and Tel Aviv. Spain has managed to rebuild diplomatic relations with both neighbors, but it hardly has any relevant agreements on defense matters. This vacuum is beginning to be perceived as a serious problem in certain strategic circles, especially when linked reports to the Ministry of Defense they already admit that “South of the Strait of Gibraltar, military pressure is a reality.” Ceuta and Melilla as vulnerable points. That is why the reports of the Spanish Institute for Strategic Studies raise with increasing clarity the need to a specific plan defense for Ceuta and Melilla. The focus goes far beyond the military and includes logistics, cybersecurity, maritime surveillance, institutional resilience and protection of critical infrastructure. Fear does not necessarily point to an open conventional conflict, but rather to hybrid scenarios constant pressure: migration crises, diplomatic tensions, partial blockades or political attrition campaigns. Autonomous cities thus appear as especially sensitive enclaves due to their logistical dependence and geographical isolation. A brutal return: geography. If you like, all this reflects something broader: the return of geography as a central factor of European politics. For years, Spain observed the Maghreb mainly from a migratory and commercial perspective, while the greatest threats seemed to be far from the western Mediterranean. But the war in Ukraine has accelerated regional rearmament and has reorganized alliances throughout the area. And in the midst of this transformation, Spain begins to discover that one of its potentially most delicate fronts is not in the Baltic or in Eastern Europe, but just in the other side of the strait.

Ukraine has resurrected one of the oldest tactics of warfare. And he is isolating Russian cities without the need for soldiers

by

One of the many movie scenes that took place during the soviet blockade of berlin occurred in 1948, when the United States and its allies kept an entire city alive using an airlift that landed every few minutes with food, coal and medicine. The operation highlighted a lesson that military strategists never forgot: in any war, sometimes the most important thing is not to conquer a city, but to decide who can continue to supply it. A silent return. For centuries, sieges were one of the tools more brutal and effective of the war. Surrounding a city, cutting off supplies, and waiting for hunger, exhaustion, or lack of ammunition to do the job was a military logic as old as empires themselves. Ukraine is now recovering that same idea, but adapted to the drone era. The big difference is that you no longer need to physically surround a city or send thousands of soldiers to isolate it. It is enough to control the roads, monitor movements and constantly destroy everything that enters or leaves. What is happening around Mariupol It is beginning to look less like a traditional war and more like a medieval siege executed from the air and hundreds of kilometers away. Mariupol as a laboratory. After conquering Mariupol in 2022, Russia turned the city into one of the ggreat logistics centers of its southern front, using its roads and port to move fuel, ammunition, troops and equipment towards Donetsk and Zaporizhia. Ukraine has started to attack precisely that circulation network. Reconnaissance and attack drones patrol the main access routes to the city looking for tanker trucks, ammunition transports or logistical convoys. The logic is extremely simple and very old: There is no need to destroy a fortified position if you can prevent it from continuing to function. According to different military sources and published videos by Ukrainian units, some drones already operate up to 160 kilometers within of territory controlled by Russia, turning entire roads into permanent risk zones for any Russian military vehicle. Turn logistics into the new front. The most important transformation of this strategy is that the main objective is no longer necessarily soldiers, tanks or trenches. They are the supplies. Ukraine is exploiting a classic vulnerability: any army depends on fuel, food, ammunition and constant transportation to maintain positions. The drones greatly facilitate that job because logistics trucks are relatively easy targets: they follow predictable routes, have little protection and often transport extremely flammable or explosive material. Even small ammunition can destroy them completely. That explains why Ukraine is dedicating so many resources to chasing supply vehicles instead of directly attacking fortified positions that are much more difficult to neutralize. From Mariupol to Moscow. The same logic also appears behind the massive drone attacks against Moscow. They remembered in Insider that Ukraine no longer uses only small improvised FPVs near the front. Now deploy long-range platforms such as FP-1 Firepointthe RS-1 Bars or the new Bars-SM Gladiatorhybrid drones between a cruise missile and unmanned aircraft capable of traveling hundreds of kilometers and crossing one of the densest anti-aircraft networks in the world. The objective is not only to cause specific damage, but to force Russia to disperse defensesspending resources and living under constant pressure even far from the front. The attack with more than 120 drones on the Moscow region demonstrates the extent to which Ukraine attempts to transfer the logic of attrition and isolation far beyond the traditional battle lines. A battle for movement. What is really important is that Ukraine seems to be redefining a fundamental idea of modern warfare: it is no longer necessary to completely control the terrain to control the situation. Just control movement. If any road can be surveilled by drones, any convoy can be destroyed and any resupply can end up intercepted, maintaining a position begins to be much more difficult even if the enemy retains numerical superiority. There is no doubt, that profoundly changes traditional military logic. The future sieges They may no longer be represented with circles surrounding cities on a map, but with invisible networks of drones capable of slowly collapsing enemy logistics without the need for major ground offensives. The war in Ukraine is demonstrating precisely that: that today you can isolate a city, wear down an army and force it to abandon positions without moving practically a single soldier.

Spain’s problem is not the lack of buildable land. It is a huge land jam that blocks three million apartments in cities

by

The brick crisis at the beginning of the century may be left far behind in time; But the truth is that, almost 20 years after the bubble burst, the sector has not yet recovered from its hangover. And that has dragged it into a paradox: although the country drags a serious deficit residential (some 700,000 homes) and prices they don’t stop going upin Spain there is a huge amount of immobilized buildable land, plots that after the crisis have ended up in the hands of municipalities incapable of promoting housing on them or of groups, funds and companies that have not been able to develop them or have not considered it viable. It might seem like a minor issue if it weren’t for the fact that there are calculations who estimate that that ‘big traffic jam’ of land is costing the cities of Spain 2.9 million potential apartments. That is, houses that could be built on developed lots, but for one reason or another they still do not go beyond paper. Just over half (1.5 million) are also concentrated in the 15 main metropolises. One figure: 1.5 million. The data comes from a study published in the last notebook of the Civic Circle of Opinion by Ignacio Ezquiagaeconomist and expert in the real estate sector. In it he basically dedicates himself to reviewing the “pending planned housing” in the main urban areas of the country. These are apartments and houses that should be built on plots of land in an “advanced state of urban development” or sectorialized (endorsed by a plan and the corresponding city council), but that still do not go from paper to work. Why is it important? Because as Ezquiaga’s study recalls, that bag of land could accommodate millions and millions of new homes. To be precise, it speaks of about seven million properties, although a good part is located in rural areas where the gap between supply and demand is not as serious as in the capitals. If we focus on the 86 urban areas of Spain, we find vacant land with the potential to host 2.93 million of housing. If we refine the shot even further and limit ourselves to the 15 main metropolitan areas of Spain, the figure remains at around 1.51 million homes. Of these, half a million would be located in areas with already urbanized land. Madrid, in the lead. In your studioEzquiaga includes a table prepared with data from the Ministry of Housing that shows that the largest housing stock planned and pending execution is located in the Madrid area, at least if we talk about raw figures. There the potential is 351,000 properties, almost 15% of the total existing housing stock in 2021. The potential is equally high in Murcia (226,600 units), Seville (142,900) and Barcelona (142,900), although in general terms it adds up to thousands of homes in all areas of the country. The smallest is Palma, with almost 12,000. In “dead hands”. To understand part of this large pool of stuck housing we have to go back almost two decades ago, to the bursting of the real estate bubble and its subsequent hangover. When brick ceased to be the business of the century and many developers were forced to close, the plots that had recently hosted residential projects began to become an asset with an uncertain future. A part ended up in private hands. Another, from the town councils. Their casuistries are different, but in the end the result is the same: what Ezquiaga calls properties in “dead hands”parked plots, stuck despite having the potential to inject millions of homes into a market that, 20 years later, is once again tense. “Judging by its urban status, blocked for more than two decades in which many have remained vacant, these are not temporary but structural situations; that is why they remind us, overcoming the distance, of those owners who went down in history as dead hands,” reflect. Who controls that land? As remember The Country There are two major fronts. 30% has remained in the hands of municipal administrations that once received them from the developers as part of the land that they had to give up to carry out their real estate projects. The problem is that not all town councils have the capacity, will or simply the resources to take advantage of that land and convert it into public housing (VPO). The result is that it ends up blocked, up for sale or redirected towards other uses, such as endowment services. The remaining 70% of the land depends on private entities, but that does not guarantee that it will be exploited and converted into housing. The key is whether or not its development is profitable. And if they can finance it. This also explains that when city councils opt for public-private collaborations to take advantage of the land they control, they do not always find partners willing to embark on the projects. One of the keys is provided by Ezquiaga in your studio: The 15 main metropolitan areas in Spain have land with potential for a million and a half homes, but only a third are located in environments with already developed land. “Vacant land”. Last year, in another study published by the think tank Funcas on the Sareb, Ezquiaga I already warned of the complexity of the scenario: “With a development industry with lower capacities compared to previous decades, the original projects were discontinued. Thus, many of the still viable lands would not adapt to the regulatory changes or the new territorial needs, paralyzing them and contributing to a surplus of vacant lands with negative consequences on the valuation of Sareb’s portfolio and, above all, for the long-term generation of new residential supply.” He is not the only one who has drawn attention to the land with still pending potential in the cities of Spain. The Ministry of Housing itself has analyzed the main pockets of land available in Spain for new apartments, focusing above … Read more

Birds in cities are more afraid of women than men

by

Walking through a park and having a pigeon, a parrot and a sparrow fly away when we approach is quite an everyday occurrence, since they see us as a threat, probably due to our large size in comparison. But the truth is that we now know that this gesture It is more common when the human approaching is a womanas if it were a genre that scared him more. They have investigated it. This curiosity has been the conclusion reached by a published scientific study in British Ecological Society in which it is noted that birds escape sooner when women approach than when men approach. And to get here, the research team did not rely on a few observations, but designed an experiment that grouped 2,701 observations across five European countries and 37 different urban species. The results. If we look at specific figures, it has been seen that when the person approaching the birds is a woman, the flight distance is approximately one meter greater than when a man approaches. And here the question we can ask ourselves is whether this is a simple coincidence, but here the researchers have made it clear that this is not the case, since the conclusion that birds distinguish the sex of the human observer is statistically solid. And to ensure this accuracy, the researchers controlled multiple variables during the approaches, including initial distance, the size of the bird school, and surrounding tree cover. Because? Although the pattern of behavior is undeniable, the exact causes remain largely a mystery, with researchers pointing to a lack of a concrete explanatory mechanism. The theories that are mainly pointed out are related to different factors, such as differences in body shape between the woman and the mobile phone or even movement, since the way of walking can be a warning signal for animals. Furthermore, it is proposed that the smell that each of the genders has is a possible hypothesis to explain this anticipated flight reaction. But the truth is still a great mystery. Survival in evolution. The fact that birds pay so much attention to humans makes sense if we take into account the enormous evolutionary pressure that cities exert, since in a very short time birds have had to adapt to our presence and above all to the pressure of having us literally on top of them in part of their environment. And little by little we are learning that not all human beings have the same effect on them.

Wolves, bears and wild boars are dividing up the map of Spain and the real battle is between the rural world and the cities

by

Wolves, bears, vultures, cormorants, wild boars, lynxes… When, a few months ago, Christian Gortázar, professor at the University of Castilla-La Mancha, was asked about Spanish wildlife, his words were tremendously accurate: “the problem is everywhere.” And dozens of species are being redistributed throughout traditional territory while rural and urban society confront each other over something extremely basic: what the hell nature is and what it is for. Why are we talking about this? Complaints from the agricultural sector about wildlife have been with us for years. However, in recent months (and spurred by the African swine fever crisis) the “mismanagement” framework has been gaining weight in public debate. But the truth is that the idea that “there are many animals and no one controls them” is not innocent. It is, in reality, a ‘discursive umbrella’: an idea-force that brings together very heterogeneous demands (the cuts from the future CAP, the fears derived from the Mercosur treatybureaucratic burdens, rising costs, rural identity, etc.). That is the main reason why the political debate does not fit with the scientific one, but not the only one. How to survive the end of the field. Talking about Spain being emptied today is almost obvious: 62% of Spanish municipalities has lost population since the nineties. In Castilla y León and Asturias that figure is around 85%. For the urban population it is only a sociological question, for the rural population it is an existential question. And in that context, the wolf has expanded to the southeast, the bear has doubled its area of ​​influence and the wild boar has sneaked into towns and neighborhoods (causing a complete economic and health earthquake). Regardless of the real effect of conservation measures on the rural world, it is easy for the feeling of general abandonment to curdle into an aversion to this way of seeing the countryside. A legitimate debate. From an ecological point of view, species recovery makes sense (as long as it is done properly). Degraded ecosystems lose the ability to adapt and become much more fragile: recovering species is the simplest and most cost-effective strategy. But we must not forget that these species return to a world completely different from the one they left and that the gaps they left are now occupied by “de facto powers” and realities historically established in the countryside and that still survive. And those powers They maintain that the ‘intervention’ of cities In their world it is counterproductive. The debate, as I say, is legitimate (and even healthy). And then? The real problem is not the discussion about whether the resources allocated to recovery measures would be better invested in other policies. The problem is that in the public debate the data and arguments are missing; and everything has become a partisan quagmire that is very difficult to manage. But the wildlife is still there. And the farmers too. In fact, all the actors who have taken us here are still there. The fundamental question is whether there is a future that can be understood as a solution.

Belgrade’s “liquid trees” are the fascinating biotechnological solution to clean the air in cities

by

Today, the city of Belgrade has a significant problem in terms of air quality, which is already something quite typical of large cities. The situation here, the truth is, is quite critical, with some areas where the limits recommended by the WHO are exceeded by up to 5 times, and to solve it, the idea that we can have in mind is need to plant more treesbut the reality is that there is little space available to plant them, so they have had to choose to install what they have called liquid trees. The solution. Under the name of LIQUID 3this project has been operating since 2021 in front of the Stari Grad City Hall in the Serbian capital, and to the surprise of many it is not shaped like a tree, but is a simple glass tank that is filled with 600 liters of water inhabited by local microalgae. But just because it doesn’t have the shape of a tree doesn’t mean it doesn’t work as such, since it literally uses photosynthesis to absorb carbon dioxide from the environment and release pure oxygen into the environment, and the truth is that they are very efficient, since a single tank of LIQUID3 is equivalent to the absorption capacity of two 10-year-old trees or 200 square meters of grass. How is it possible? That a simple tank surpasses an adult tree when it comes to ‘purifying’ the air, the truth is that it seems strange, but biotechnology has achieved something incredible. Specifically, science has seen how microalgae have the ability to capture carbon dioxide and fix it between 10 and 50 times faster than land plants under controlled conditions. In fact, studies indicate that these algae can fix approximately 1.8 grams of CO₂ for every gram of biomass generated, achieving CO₂ removal efficiencies close to 50%. And designed for the city. Being in the center of a city is not easy, and that is why scientists have had to use strains of Serbian freshwater microalgae that grow with simple tap water and withstand extreme temperature fluctuations. And here the research indicates that these species are ready for the most hostile environments. And another positive point they have is that they hardly require maintenance, since it is limited to the fact that the biomass generated must be extracted every month and a half, and in addition, water and fresh minerals are added. The positive here is also that biomass can be used as a great natural fertilizer. More than a lung. The LIQUID3 is not just a laboratory experiment that has taken to the streets, but has been designed as multifunctional urban furniture, since, in addition to purifying the air, the structure functions as a bench to sit on and even adds solar panels to charge your cell phone or provide night lighting. It is not definitive. Although it seems incredible, the truth is that we must put our feet on the ground in the face of technological enthusiasm. Although right now the figures are very good, there is still a lack of studies that can validate the impact it has in the long term and measure whether they are really giving good results, and above all that they are real. But the most important nuance here is that these systems do not replace traditional trees or forests, which logically must remain where they are and promoting their implementation. In this way, we are left with the fact that this technology has been designed for dense and highly polluted urban areas where traditional planting is logistically impossible. Where the asphalt does not give an inch to the roots, the liquid trees rise like a high-tech green oasis, giving the city’s lungs a break.

This cool 3D map of light pollution turns cities into mountains of light

by

This 2026 is the year that opens a fantastic period to enjoy astronomical milestones, since the first of the three eclipses planned between 2026 and 2028: it will be next August 12, it will be a historic event in these latitudes (it has been more than a century since the Iberian Peninsula has witnessed a total solar eclipse) and not everyone will be able to see it: It will only be total in a strip. Being in the right place at the right time is only the first step: the next thing to be able to enjoy both the solar eclipse and any astronomical event, or simply to be able to see the stars well and distinguish constellations is total darkness. Or at least, try to be in a place free of light pollution. Getting away from the big cities is the first step as they tend to be the main sources of light, but not the only one: there are many infrastructures that can spoil the experience. Our recommendation if you plan to see the solar eclipse is that you do not leave it to improvisation and be clear about where to go to enjoy it better and here in addition to the map of the National Geological Institute To follow it, it is worth having on hand a good light pollution map. Where the solar eclipse will be seen: areas where it will be total and areas where it will be partial. IGN But does a light bulb next to you bother you so much to see the sky?? Yes, essentially because it is never usually just a light bulb. In fact, it’s not even just too much light. An example: when you approach a city with your car and it is getting dark or it is night, you can see a glow of the sky (skyglow) fruit of the rebound of light against dust particles, humidity and aerosols in the atmosphere, returning as a luminous veil that destroys astronomical observation. The underlying problem is the increase in the brightness of the sky: a star or a nebula does not compete against darkness, but against that background. If the background is brighter, the contrast drops (excepting the distances, it is like cheap TVs with bad backlighting scheme). The heavens are measured by the Bortle scalewhich goes from 1 to 9 where a class 1 sky is the darkest possible, practically a miracle in continental Europe (most medium-sized cities are around 7 – 9). With a class 9 sky you can barely see the brightest stars and the moon. Where not to see the solar eclipse of August 2026 And it does not only affect large cities (in Madrid it can be seen from quite a few kilometers away), but also industrial areas and ports. In these cases, it is also usually permanent lighting without any control. Also the road networks. A picture is worth a thousand words: the map by cartographer and geospatial developer Jacob Wasilkowski and Petrichor Studio called Earth at Night. Earth at night. JWasilGeo & Petrichor Studio This map combines several sources: night light data comes from NASA (Suomi-NPP satellite, VIIRS sensor) and background satellite mapping is provided by Earthstar Geographics along with other commercial providers integrated into Esri’s World Imagery service. The technological infrastructure to render it in 3D is also from Esri, a Californian company specialized in GIS software. Wasilkowski is the one who has put it all together to convert luminosity into topography. Simply put: It has converted the luminosity of NASA’s nighttime images into elevation, so that cities are mountains. The bigger the city, generally the bigger and higher the mountain will be. Note that there are areas, such as northern Italy or the German border with Belgium, that are real garlands. In the Iberian Peninsula, the Mediterranean coast, the Portuguese coast and a point in the middle of everything stand out: Madrid. These are the areas to escape from if we want to see the sky well. Earth at night. JWasilGeo & Petrichor Studio And just the opposite, the valleys are the most interesting areas to observe the eclipse or any other astronomical milestone: they are the dark areas. Although its controls are intuitive, you have options to switch to the satellite layer, you can zoom, pan and rotate. The map is a few years old now, but for those of us who like to observe the sky it is a good idea to always have it at hand. Furthermore, when this map was launched a decade ago it had a great impact on the cartographic community, winning the award GOLD from the KANTAR Information is Beautiful Awards 2019 in the category “Maps, Places and Spaces”, under the name “Earth at Night, Mountains of Light”. And why not say it: it is evocative. After all, it uses real light captured from space to re-sculpt the Earth, letting it be human activity that defines its topography.

The great battle of the Ebro is not between Murcia and Aragón, it is between the headwaters of the rivers, the large cities and the delta

by

The image is straight out of a movie: a team of divers diving into the cold waters of the Arija reservoir to dredge more than three meters of silt accumulated in front of its floodgates. It’s not a whim, It’s the only way to remove them.: that is, the consequence of having hundreds of infrastructures that have not been thoroughly maintained for decades. But, above all, the most striking symptom of a very deep problem: the sediments are killing, at the same time, the reservoirs and the rivers. Reservoirs due to loss of capacity (Mequinenza has lost since its opening more capacity than the sum of the last three reservoirs put into operation), rivers because deltas need sediment to stay alive. The Ebro, without going any further, needs 1.2 million tons per year. And the authorities know it. In fact, since 2003, the Ebro Hydrographic Confederation has been carrying out controlled floods in the lower section of the river to mobilize sediments towards Tortosa. The problem is that each controlled flood moves about 10,000 tons; that is, two orders of magnitude below what is necessary. It’s like emptying a swimming pool with a coffee spoon. So in the last few months, something has changed. Since November 2024, the CHE began a series of measures to try to fix it. Things like extending the discharge by two days, starting it from much higher up (El Grado in Huesca and Camarasa in Lleida) and draining Ribarroja more than usual to mobilize all the possible sediments. Will it solve the problem? It’s not clear, but it doesn’t seem like it. We have to take into account that, only in the Ebro basin, there are many reservoirs and that is an inevitable brake. Calculations say that of the five million tons that were brought to the Mediterranean before the reservoirs, only between 100,000 and 200,000 now arrive. It would take around 100 floods to reach the appropriate figures. And no, we don’t have enough water for that. So? That is the big problem, seeing what we do. We must not forget that the Ebro delta supports 20,000 hectares of rice fieldstens of thousands of inhabitants and is a biosphere reserve. The loss of wetlands and their salinization have a direct impact on agriculture, fishing and tourism. Come on: the interests are crossed and they confront people hundreds of kilometers away. We are entering a new era of hydrological wars in which we are all against each other.

Spanish cities are collapsed because they were not designed to go “from the periphery to the periphery”

by

For decades, commuting to work in large Spanish cities had a clear logic: workers lived on the outskirts of large cities and They traveled every morning towards the center to their jobs. It was a fairly stable urban model, reinforced by transportation networks designed to take workers to the large office districts of the urban area. However, in recent years this pattern has been changing as the price of land in the center has skyrocketed and companies have also had to move to the periphery. As and as it portrays The Countrythe problem is that cities are not designed to move from periphery to periphery, and that movement has become in a daily mousetrap for millions of employees. In recent years, many companies have chosen to move your offices to peripheral areas where land is cheaper and there is space to build large office complexes. This movement has made it possible to build huge business campuses that would be unviable in the urban centers of large cities with high demand for land such as Madrid or Barcelona. In Madrid, the north of the city has become one of the main destinations for this type of projects. An example is the Telephone Districtlocated in Las Tablas, which occupies about 22 hectares and concentrates more than 12,000 workers in a single business complex. The records of the Residence-Work Mobility Atlas of the Community of Madrid show that districts such as Fuencarral-El Pardo (where the Telefónica District is located) are already among the areas with the highest concentration of employment in the region. Barcelona experienced a similar process with the development of 22@ technological district in Poblenou, where numerous technology companies and corporate headquarters have been setting up shop in the last two decades. The transformation of this old industrial neighborhood created a new employment center outside the historic center of the city. Employment is moving, but so are prices The problem with this migration of companies to the periphery of urban centers is that when thousands of workers begin to concentrate in a specific area, the real estate market usually reacts quickly. Proximity to work centers increases the value of neighborhoods nearby, which ends up raising rental and housing prices. This increase, in turn, forces employees to move to municipalities even further away from the city center and the offices where they work. The result is a constant increase in daily trips within the metropolitan area. In Madrid this phenomenon is reflected in the labor mobility figures. According to the recorded data According to the Mobility Atlas of the Community of Madrid, every day 1.2 million people enter the capital from other municipalities to work, compared to the 790,000 who did so in 2016. Something similar is happening in the city of Barcelona, which after the growth of 22@ has attracted workers from numerous municipalities in the metropolitan area, congesting the northern and southern access roads and the city’s ring roads due to the traffic generated by these employees at peak hours, such as and how collect traffic congestion report of Inrix of 2025. All these congestion problems have their origin in the fact that the large transport infrastructures (metros, trams, Cercanías, bus lines, etc.) of the large Spanish cities have been designed for decades with a radial structure. They were planned to connect the peripheral neighborhoods with the city center, which was where most of the employment was concentrated. When new business centers began to grow outside the center, that structure began to show its limitations. Many workers no longer need to go to the urban area, but rather travel between peripheral areas that are not directly connected by public transport. A very clear example of this is the demand of the residents of Tres Cantos for an axis that connects them with… The A-6, not with the center of Madrid. This requires long journeys or several transfers, something that often makes the car faster. Even if it means getting stuck every day on the way to work. Furthermore, public transportation in many cities has become a lottery with constant delays and breakdownswhich generates uncertainty when considering alternatives to the private car. The increase in long trips to work and dependence on the car is clearly reflected in traffic data. According to the TomTom Traffic IndexMadrid registered an average congestion level of 38% in 2025, which is 3.6 percentage points more than the previous year. That level of traffic means that traveling 10 kilometers during rush hour can take about 34 and a half minutes, at average speeds. close to 17.5 km/h. The report also estimates that Madrid drivers lose around 98 hours a year in traffic jams during rush hours. When daily journeys are long, the accumulated time can multiply and reach up to 500 hours per year per person lost in traffic jams. Barcelona faces a similar situationwith a level of congestion in its urban center and access roads of 41.1%, which is one of the highest figures in Europe.

Iran has spent decades excavating its “missile cities.” Satellite images have just revealed that they are a death trap

by

For years, Iran has shown the world tunnel videos endless tunnels dug under mountains, with military trucks circulating between missiles lined up as if they were cars in an underground subway. It was understood that many of these facilities extend kilometers underground and are part of one of the military fortification programs. most ambitious in the Middle East. What almost no one knew until now is to what extent this gigantic hidden labyrinth could become a key piece of the current conflict. The cities, but with missiles. Yes, for decades, Iran has excavated an extensive underground base network known as “missile cities”, complexes hidden under mountains and hills intended to protect its enormous ballistic arsenal against air attacks and guarantee the regime’s retaliation capacity even in the event of open war. There are numerous videos Officials released in recent years where we could see long tunnels illuminated by artificial lights, windowless corridors and convoys of trucks loaded with missiles ready to move to the surface, an entire military architecture designed to hide thousands of short and medium range projectiles away from spy satellites and enemy bombers. Some installations even incorporate silos dug into the rock or mechanical systems on rails to move missiles within underground galleries, a perfectly assembled choreography reflecting a strategic project conceived to ensure arsenal survival Iranian in a protracted conflict. The images that reveal the paradox. However, the war has begun to show the unexpected reverse of that strategy. Recent images from space have revealed Smoldering remains of destroyed launchers and missiles near the entrances to several underground complexes, a sign that systems hidden underground are becoming extremely vulnerable at the moment when they must go outside to shoot. It makes sense. American and Israeli surveillance planes, armed drones and fighters They patrol constantly over the areas where these facilities are located, observing the entrances to the tunnels and attacking the launchers as soon as they appear on nearby roads or canyons. In other words, what for years was a system designed to hide mobile weapons It thus becomes a relatively predictable pattern: tunnel entrances, exit roads and deployment areas that can be monitored from the air and destroyed as soon as activity is detected. From strategic refuge to death trap. They remembered in the wall street journal A few hours ago this change has revealed a structural problem in the very concept of missile cities. Underground complexes are very difficult to destroy from the air, but they are also fixed installations whose location is known by Western intelligence services. In practice, this means that much of the arsenal remains stored in specific places while enemy planes continually fly over the airspace, waiting for the moment when the launchers come out to act. Many military analysts summarize the dilemma in a simple way: What was previously a mobile and difficult to locate system is now concentrated in fixed points, which facilitates its surveillance and reduces its capacity for surprise. Commercial satellite images themselves show destroyed launchers As soon as they left the mouths of the tunnels, fires were caused by leaked fuel and access to facilities bombed with heavy ammunition.

As the first week of war approaches, the military campaign has begun to focus increasingly on these infrastructures. They told Reuters that the first phase of the attacks focused on destroying visible launchers and surface systems capable of firing at Israel or US bases in the region, while the second stage aims straight to the bunkers and buried warehouses where missiles and equipment are stored. Israeli aviation, with American support, has attacked hundreds of positions and has managed to drastically reduce the number of launches, while an almost constant air offensive that hits targets continues. both in Iran and Lebanon during the same missions. The stated objective is to progressively degrade Iran’s ability to launch ballistic missiles and drones until it is completely neutralized. Missile base north of Kermanshah in Iran. The image on the left belongs to February 28, on the right it belongs to March 3 A gigantic arsenal underground. The actual scope of these facilities remains difficult to determine. There are military estimates that place the Iranian arsenal before the war between about 2,500 and up to 6,000 missilesstored in different facilities throughout the country, many of them excavated under mountains or in remote areas of the territory. Despite the attacks, Iran has managed to launch more than 500 missiles against Israel, US bases and targets in the Gulf since the start of the conflict, although many have been intercepted and the pace of salvos has decreased rapidly. That drop suggests that attacks on launchers and storage centers are beginning to erode the country’s ability to respond. The strategic dilemma. The result is a strategic paradox that is just beginning to become visible. Missile cities were designed to protect the core of Iranian military power and ensure its ability to retaliate, but in a scenario where the enemy dominate the air and watch constantly the entrances to these complexes can become choke points for the arsenal itself. Iran has spent decades excavating these underground bases with the intention of making its missiles invisible. But satellite images of the war are showing something very different: that this labyrinth of tunnels, designed as a shelter, can become one of its greatest vulnerabilities when the launchers are forced to surface under the look constant flow of planes, drones and satellites.
