Almería

In 1850, Almería inaugurated one of the largest hydraulic works in 19th century Spain. It was a complete disaster

by

It is May 8, 1850, Níjar (Almería). Although the promoters have been trying for months, finally the inauguration of the Isabel II reservoir will not have the physical presence of the Queen which gives it its name. But they are not going to let that ruin the moment, their moment. We talk about what may be the largest hydraulic work of the Andalusian 19th century and one of the most ambitious on the peninsula: 35 meters of stonework built at will by more than a thousand private investors that culminate the old dream of the Duchess of Abrantes, to build a dam along the Rambla del Carrizal. A dam doomed to failure. Money in abundance. In 1821, in the heat of the mining boom in the Sierra Almagrera of Almería, Diego María Madollel He created ‘Irrigation of Níjar’ and obtained tax exemptions from the crown. The idea was simple: build a stone structure 44 meters long and 35 meters high with the idea of ​​irrigating more than 18,000 hectares in Campo de Níjar and Campohermoso. Over the next 40 years, Madollel would learn that there are many ways to fail. The first was almost immediate. The second took almost twenty years and the third, in 1842, with the constitution of the Níjar Reservoir Company, seemed to be the good one. The businessman gathered more than a thousand shareholders from Almería, Murcia, Málaga, Madrid and Valencia (people who had become rich from the mines, wanted to invest, but did not know much about the matter) and got the state to declare the project a ‘public utility’; but, five years later, the project could not get off the ground. It wouldn’t have started, but In 1848 the drought began. A persistent, sharp and prophetic drought… but that promoted the construction of the swamp. Madollel saw his opportunity and began selling water rights. The construction moved forward, the Murcian Jerónimo Ros took control of the construction and by 1857 not only the dam was finished, but also a very complex system of irrigation canals and pipes. Madollel had built a hydrological Ferrari: but the road was not in condition to go more than 20 kilometers per hour. How much everything goes wrong. Despite the very long development, the promoters did almost everything wrong. To begin with, they did not carry out hydrological studies of the area and that prevented them from realizing that the riverbed did not have enough flow to fill the reservoir or to irrigate 18,000 hectares. Furthermore, they did not realize that the regime of the boulevard was ‘torrential’: when it rains, it does so torrentially and that causes enormous amounts of sediment to be washed away. By 1871, the reservoir was completely blocked. The failure was enormous. Or almost. Because, although it is true that today the prey is a relic for hikersthe truth is that Madollel did have some vision. Today the Campo de Níjar is the epicenter of one of the largest seas of plastics in the country. The hydrological pressures are the same or worse, but this shows that it doesn’t matter how many times the climate twists our hand, the man is there to try again.

There is a corner of Spain that God has taken a liking to: Alicante, Murcia and Almería

by

“In Murcia there has to be a tarp or something, it’s not normal.” It José Montiel said while looking at a map with the rain that is going to fall in Spain in the coming days and the truth is that it is difficult to disagree. In the last few hours, we have had the combination of a trough and a river of humidity that have produced a squall line over the peninsula, leaving in its wake intense winds, considerable rains and many storms. Everywhere, less in the southeast. What happens in Alicante, Murcia and Almería? Strictly speaking, nothing new happens. The southeastern corner of the peninsula has been recording national minimums throughout the modern period. It is enough to look at the stations around Cabo de Gata to discover that the annual accumulations are very low (around 200mm/year) and if we go a little further inland, to Tabernas for example, the figures are only about 50mm higher. Although with enormous irregularity, yes. It is not surprising, therefore, that desertification is devouring that corner of Spain. Nor does the Köppen-Geiger classification indicate that these are the most arid climates in the country (rivaling only some areas of the Canary Islands). But why? There are three fundamental reasons that explain why the southeast of the country receives so little water. The Azores anticyclone: The great Atlantic plug affects a large part of the country, it is true. We must not forget that, according to the latest studies, Spain faces the driest climate in its last 1,200 years and the progressive strengthening of that anticyclone is to blame. However, due to the trajectory of the winds in the northern hemisphere, not all parts of the territory are affected equally. You just have to compare the climate regime of Galicia with that of Murcia. The Betic mountain ranges: Although we sometimes tend to forget it, in the south of Spain there are a series of really high mountain ranges. The highest mountain on the peninsula, in fact, is in the Baetic mountain ranges. These constitute a true orographic wall that intercepts humidity and generates a very long rainfall shadow over the southeastern coast. Come on, the water stays west of the mountains. Evapotranspiration totally uncontrolled: We are talking about an area with very high insolation and very high evapotranspiration. It’s not just that it rains little, it evaporates a lot and that generates a “deserted” terrain that is unable to take advantage of the rains when they arrive. And that, in an area where DANAs are key, is a problem. Everything is getting worse. We might think that all this is normal and yet it is not. We are inserted in a time of changes and IPCC forecasts are gloomy: to the Mediterranean as it is one of the places in the world where the reduction in precipitation is most directly linked to warming. It is estimated a drop of 4% for each degree more in the central and northern Mediterranean. The best example is this same 2025. Despite the historic rains that have occurred this yearthe balance of the southeast will be bad. And, while illegal water trafficking schemes continue to grow, There are initiatives to continue building transfers that they bring to the region the liquid that does not fall from the sky. The problem is that, whether we want to see it or not, we need more far-reaching changes than what we currently seem to be able to assume.

Almería has been the great “plastic sea” of Europe for years. Now he wants to be another sea: that of solar panels

by

During the First Andalusian Congress on Agriculture, Energy and Water held at the University of Almería, a path that begins to materialize today was already glimpsed. In that meeting, Professor Ángel Carreño He stressed that the use of photovoltaic plates In greenhouses, intensive agriculture could revolutionize. “With just 1% shadow with solar panels on the roof, the energy needs of a greenhouse could be covered,” he said. Seven years later, this forecast is specified in a pioneering project that aims to make a qualitative leap to the Almeria agricultural model: Dynamic Aquasave. From the plastic sea to the energy sea. The scenario of this innovation cannot be more unique. NASA confirms that the “plastic sea” Almeria is one of the few human constructions visible from space. According to the BBCunder its 32,000 hectares of white plastic, about four million tons of foods are produced every year to export them to Europe, generating about 5.1 billion dollars annually, which represents 40% of the GDP of the province. It is in this context where Dynamic Aquasave arises, with the promise that the plastic sea can be transformed into an energy sea, capable of producing not only food, but also electricity. How will it be? The University of Almería, together with Barre greenhouses, the Technalia Technology Center, the Uual-Anecoop Foundation and with CDTI financing, leads this project. The contract was signed in November 2024 and was ratified in February 2025 In the official act of the Department of Engineering of the UAL. The system consists of installing transparent or semi -transparent solar panels on the greenhouse cover, which are automatically oriented thanks to an algorithm. These panels fulfill a double function: they act as a dynamic shade to control excessive radiation and, at the same time, generate electricity. As He explained Professor Diego Luis Valera to Diario de Almería, “integrates, in the same system, photovoltaic generation and dynamic shadow governed by algorithms, something that does not exist in the market with the parameters required by a greenhouse adapted to the southeast of Spain.” The planned benefits are clear: up to 30% water savings, less needy need, a more stable microclimate, energy for self -consumption or sale and better working conditions within greenhouses. Forecasts The Dynamic Aquasave prototype will be installed at the Uual-Anecoop Foundation, where a greenhouse will also be enabled to compare yields. The experimentation phase is scheduled for the fall of 2025 and will last at least two agricultural campaigns. The project also has the collaboration of the University of Córdoba, which develops specific software and hardware for the control of the orientable panels. The combination of agricultural engineering, artificial intelligence and renewable energy makes it a unique proposal in the international scene. The digital layer. Dynamic Aquasave is not just solar energy. According to has detailed Valera to Diario de Almería, also seeks to provide the field of an artificial intelligence layer. With sensors and automatic learning algorithms, the system can predict dates and kilos of harvest before cutting, adjusting irrigation and nutrient supply in real time, and reducing the water and carbon footprint. In addition, the equipment works in passive microclimate systems: low -cost solutions that allow regulating temperature and humidity without spending energy, favoring biological pest control and reducing inputs. The project also supports international research and transfer networks, which seek that these innovations do not stay in laboratories, but arrive as soon as possible to real farms. Although the problems are not going to go. The European garden also drags criticism. Technology can relieve some challenges, but not solve them all. No algorithm can, by itself, reverse the overexploitation of aquifers or the social problems of the Almeria field. On the one hand, academic investigations cited by the British environment They remember that growth has been sustained thanks to the overexploitation of underground aquifers, some in deficit for more than two decades, and that 30,000 tons of plastic waste are generated every year. On the other hand, The newspaper El Salto The other face denounces: migrant workers living in precarious settlements, with low salaries and marathon days. Although Dynamic Aquasave represents a technological leap, but the Almeria model also needs to face its social and environmental side. A challenge beyond energy. Although We have already explained in Xataka As solar panels can be an improvement for crops, the challenge, however, goes beyond engineering. The key will be that the plastic sea not only becomes a sea of ​​solar panels, but an agricultural space that combines innovation with social justice and environmental sustainability. Only then, Almería may go from being a green miracle to become a world agriculture model of the future.

An earthquake has shaken the coast of Almeria. And Middle Andalusia has learned thanks to Google

by

An earthquake of magnitude 5.5 located in Almeria waters has shaken multiple locations Andalusians in Almería, Granada, Jaén and areas of the Spanish Levante such as Murcia. Along with it, thousands of Android mobile users have received an unknown notification to date: a directly related to the detection of farms. The earthquake. According to information from National Geographic Instituteat 7:13 a.m. on July 14, there has been an earthquake of magnitude 5.4 to two kilometers deep in the corporal of sticks, having special incidence in populations of the Andalusian coast. The consequent replicas have lasted until 8:49, with intensities of 3.4 and 2.7. Local media They report that at the moment there have been no consequences of gravity, ensuring the 112 that “no damage to the region has been notified by the earthquake.” The message. Virtually immediately, Android phones have issued an automatic notification to thousands of phones through Google Play services. This alert is framed within the Google seismic detection system, Shakealert. In it, the estimated magnitude of the earthquake is noticed as well as recommended practices to keep us safe in earthquake cases. Through a map, both the time and distance from the earthquake are shown, with the possibility of consulting the latest updates through the same section. How it works. Google’s Seísos alert System It is more than curious. In the United States (California, Washington and Oregon) uses a network of 1675 seismic sensors to detect tremors and earthquakes. Outside these territories, the seismographs are our own phones through the accelerometer. If a phone detects movement changes that can be interpreted as an earthquake, send a signal to the Google server. At that time, the server combines this signal with that of other phones to try to find out if an earthquake is taking place. In case of determining what is taking place, an alert is sent on two levels. The key to using this system is that it works predictively. In fact, Google warns that these notifications can reach even before the earthquake occurs. The alerts. The network of more than 2,000 million Android devices, according to Google, acts as a minisismographers front capable of giving precise data on the earthquake. In the event that the alert is of 4.5 or higher scale (in MMI scale, no Richter, here is measured in surface perceived, not energy released from the epicenter), a strong sound alarm is sent ignoring the modes not to disturb and lighting the screen. If the alert is of lower magnitude, such as the one lived today, only an informative notification is sent. What about Es-alert. The doubts that have assaulted upon receiving the alarm have to do with the alternative system we have in Spain: Es-alert. Here we have a system with three levels of alert and civil protection as in charge of sending the notification through Cell Broadcast (radio emission without having active mobile data). System Who detects Who sends the alert How the alert is sent You need Internet connection Android Earthquake Alerts System Android phones themselves, through their sensors Google Push notifications Yeah es-alert National Geographic Institute (IGN) Civil defense Radio emission (Cell Broadcast) No In this case, Es-Alert has not worked. The system is active, working, and detecting cases Like fire in Tarragonabut it is Civil Protection who determines the supposed severity of the phenomenon and whether or not notification is to be sent. The legal framework. A Law 17/2015, of July 9, of the National Civil Protection System determines that only the competent authorities can issue official alerts: Civil Protection, Aemet, IGN or the communities and municipalities themselves. Private companies cannot issue official alerts … but they can send private notifications that do not violate any law. That Android informs you about a possible earthquake It does not differ too much than the time app I inform you that it is raining in your area. Google notices do not supply these official notification systems, act as an informative complement to the official framework. Here the debate enters into the own responsibility of a private company to alert the population of a gravity event as an “unofficial” earthquake. One that clashes with the slowness (or direct inactivity according to circumstances) of national systems in specific cases like this.

While reservoirs from all over the country reach record figures, Spain still has a black dot of the drought: Almería

by

For eighth consecutive week, Spanish reservoirs have risen again. It was to be expected: the same rains that have “bitter” vacations to many during Holy Week are now becoming good water news. For the first time in many years, Spain has exceeded the 75% barrier in reservoir water. And yet, this enthusiasm does not reach a very specific area of ​​the country: The Southeast. Where the rains do not arrive. If we see an autonomous map of the country’s water reserves, we will see all of Spain in blue (light, medium or dark). All except Murcia; That, at 36.49% of its capacity, it can only appear in colors close to orange or red. And, although Reservations have grown a lotthe safe basin is still very touched with 10 points less than the historical average. For more Inri, it cannot be said that it is a management problem (although the management of the basin has always been a controversial issue). It is something that extends, as I say, to all southeast. The province of Alicante is at 31.75%. That is to say, above the terrible data last yearbut without reaching the average of the last decade. And then there is Almeria. Almería? What happens in Almeria? That hides among the excellent data from Andalusia (60.59%) and the more than good of the Andalusian Mediterranean basins (55.54%), The province of Almería has a huge problem: its reserves are 11.16%. Slightly better than a year ago, but still below Lbetter 2024 data. Almería’s problem with water is not new. That’s true. If we look, the historical average of the last 10 years in The province is 13.13%. Very slightly above the current figures. And we talk about a place with a huge weight of water intensive industries (agriculture and tourism); one that, in addition, is suffering like nobody Desertification problems and overexploitation (and pollution) of aquifers. As They said a few weeks ago from Ecologists in Action“Seeing Llover away the ghost of drought”, but in areas like Almeria that drought has been anywhere. It is a false impression that only management can difficulty. Lose the water war. At least there are three Almeria regions in which drought not only persists, but It is completely chronified: Níjar, Sierra de los Fizodes and El Levante. And that we talk about the Spanish province that adds the greatest number of rafts of different sizes and characteristics (27,000according to the latest estimates). In 1987, “the first reports on the deterioration of the aquifers of the Dalías field were announced, the point where intensive agriculture was born.” And the problem has only increased: “Every year, Almería starts its agricultural campaign with a structural deficit of around 200 cubic hectometers.” The story is simple, too simple. Almería wanted to become the great laboratory against desertification, but has become a battle territory. A battle that little by little We are losing.

The future of Murcia and Almería is to become great deserts. And that of much of Spain too

by

The droughts arrive and pass by leaving behind greater or lower ravages. Also the drought that chronicly ravages Spain will have more or less intense moments, but perhaps the normality that is behind it is not like the previous one. The reason is the existence of a tendency towards long -term aridity, Aridification of the territory. A good part of the Peninsula is classified based on its aridity index as semi -arid areas, “one step” of this classification as a arid zone, according to the data of the EEENS itself. Where this process is going to advance. It is one of the points that have transcended ““B of the Higher Council for Scientific Research of the CSIC. Where do we come from. Almería, Murcia and the Canary Islands archipelago have traditionally been the areas where Spanish arid areas were concentrated. It is therefore not striking that the two provinces of the southeast peninsular are where the aridification process has had greater impact. At least until now. And it is that a good part of the Peninsula is classified based on its aridity index as semi -arid areas, “one step” of this classification as a arid zone, according to the data of the EENS itself. Potential for desertification. According to The Ministry for Ecological Transitionthe extension of these arid and semi -arid areas, to which the dry subhummedas should be added, delimits the area where the risk of desertification It must be seriously considered. According to the most recent data in the Ministry, areas with high or very high desertification risk, although they are distributed throughout the country, cover a more significant portion of the provinces of the Levant and the Southeast peninsular (In addition to the Canary Islands). The “very high” risk areas are particularly notable in provinces such as Almería, Murcia, Alicante, Granada and even Cuenca, and slightly less noticeable in some of the border provinces. Risk of desertification in Spain. Ministry for ecological transition and demographic challenge. A long -term trend. There are numerous factors that help explain why we are facing this situation. The first is the lack of rains. Beyond the current drought, the last decades have been relatively dry in Spain. Climate change is expected to aggravate this, with less rainfall on average, but more concentrated. Precedents. 2023 and 2024 were not only anomally dry: also especially warm. The increase in temperatures implies an increase in the evaporation of the water that comes to us, both from rivers and swamps and from the same soil: in spring this year the moisture of the soil was of about 0% In most of the Peninsula. Finally, water use should be mentioned. Population growth, tourism and an agriculture increasingly dependent on irrigation bring each time More pressure on reservoirs and aquifers. The latter In a limit situation. No solution to sight The combination of all these factors makes the solution difficult. Spain has a vast network of desalination plant, but the energy and ecological limitations they present prevent (at least for now) a use at sufficient scale. An example of this is the situation in Catalonia, where drought has not been able to be stopped with desalists working 100% of their abilities. Greater efficiency in water use could help complement these new sources, but here the limitations are also important: approximately three quarters of the water consumed in Spain are used by the agriculture and livestock sector according to Aquae data. The precarious situation of the sector and the recent protests do not invite to think that there is a margin of action on this front. In Xataka |The droughts are going to more.
