China is diverting its largest rivers thousands of kilometers away. The price to pay is a huge environmental mystery

Water in China has a basic geographical problem, since the south of the country floods very frequently while the north is in a drought situation. To solve it, the Asian giant has spent decades running which is probably the most ambitious hydraulic engineering project in the history of humanity, since they are literally moving nature. Making history. If there is a country capable of altering the face of the Earth to guarantee its economic and demographic survival, it is China. The premise is as simple to understand as it is pharaonic to execute, since what they are doing is transferring water from the rich Yangtze River basin in the south to the arid plains in the north, where a large part of the country’s population, agriculture and industry is concentrated, but barely 20% of its water resources. The result of this It is the ‘South-North Water Transfer Project’ that has a colossal network of canals, pipelines and pumping stations that are defying geography. The figures of a titanic work. To estimate the size of this project, it is enough to go to official sources, since, according to the latest updates from China’s Ministry of Water Resources, the infrastructure is unparalleled in the world. Specifically, to date, the system has managed to transfer more than 70,000 million cubic meters of water through its central and eastern route. From a hydrological perspective, as detailed in CEDEX technical schemes on platforms such as Hispagua, this is equivalent to moving entire rivers artificially. The beneficiaries There have been 150 million people who have seen how this water injection It has even allowed an “ecological replenishment”, recovering the water table in northern areas that had been depleted for decades. But massive intervention on the ground always has a “B side.” The rivers. As China redraws its water map, an alarming fact emerged, as official censuses revealed that tens of thousands of rivers appeared to have disappeared in the country in just a few decades. Here the specialist media have raised great global concern about this phenomenon, since it is not known if this transfer was drying out the country at an unprecedented rate. The answer. It was given to us by an article published in 2019 that pointed out that the massive “disappearance” of the channels was not due to the fact that they had evaporated overnight due to dams or climate change, but rather to a problem of cartographic methodology. That is, historically, censuses included what scientists call ‘pseudo-rivers’ and used counting criteria that were not supported. Now that they have applied a much better and more consolidated hydraulic classification, the number of these “lost” rivers has been drastically reduced. The ecological cost. The fact that rivers are not disappearing en masse from the maps does not mean that the megaproject is free, since modifying the flow of some of the most important basins on the planet entails risks that scientific literature has been monitoring for years. Already in 2009, a classic review published in Wiley by researcher Zhang Quanfa warned of the profound Yoenvironmental implications of the transfer. Here he proposes that extracting such massive volumes from the south irreparably alters the Yangtze basin, causing an alteration of the southern aquatic ecosystem, or it has even been seen that as less fresh water reaches the mouth of the Yangtze, sea water penetrates inland, threatening the local supply and agriculture of the delta. The demographic cost. Added to these environmental warnings is the institutional analysis of experts such as Mark Wang and Chen Li who point out the governance challenges and the enormous political and social friction generated. Here different critical organizations point out that the authorities have forced the resettlement of hundreds of thousands of people and have required multimillion-dollar investments in treatment plants to prevent contaminated water from the south from ruining the reserves in the north.

In the middle of the chaos because of the environmental badges, the DGT has shown the red label to Spain. It’s excellent news

Spain has just taken the most important step to date in relation to the legal framework for the circulation of automated vehicles. The DGT has announced the Safety and Technology Evaluation Framework Program of Automated Vehicles (ES-AV Program), The new regulatory framework under which all those operations related to Automated vehicles On traffic open. The red label. In the next few days, it is more than likely to start listening to the new “red label.” It is one that has nothing to do with the system of DGT environmental labelsready of suffering modifications by the government. Soon you will begin to see on the windshield of all that automated vehicle that wants to perform open road tests. It will be the way we will have to recognize that a vehicle, be it prototype, in pre-homologation phase or driven remotely It is moving autonomously. In the face of cameras and agents of the authority, it is the legal proof that said vehicle has the necessary authorization to circulate without physical supervision. The new legal framework. The ES-AV program is a national code that regulates how, where and under what conditions you can test with autonomous cars in Spain, without the need for human supervision on board. In it, vehicles with levels of autonomy are reflected SAE 2 A SAE 5as well as those driven remotely. There will be a total of three access and authorization systems, under the umbrella of the General Sub -Directorate of Mobility Management of the DGT itself. EEE Recognition System: Recognition of tests already authorized in other countries of the European Economic Space. Special system: independent evaluation in Spain. External evaluation system: Exceptional tests for vehicles have already obtained authorization in countries external to the EU. The test phases. The DGT establishes three test phases in its program, depending on technological maturity and the range of open road operations. Each of these phases establishes what will be the minimum requirements to be met, and it will be those responsible for the autonomous vehicles that will have to inform about which phase they want to participate. Phase 1, controlled: operational environment of up to three vehicles, not admitted vehicles with level 2 SAE of automation, mandatory that there is always a safety operator on board, restricted circulation space. Phase 2, extensive: simultaneous operation of up to 10 vehicles, operator always aboard, without restricting space. Phase 3, pre-despleger: simultaneous operation of more than 10 vehicles, optional on board, remote operator, exceptionally, it can be circulated with definitive plates from the EU. Sae 2 vehicles admitted. Transparency in data. Since the entry into force of this new legislative framework, the DGT will reflect on its website the data with the ongoing tests. In the same way, it establishes the obligation to the testers to deliver periodic reports of the operations carried out, not having detailed on the website the data that it will require in them. On the DGT website, we can observe some of the tests already carried out in Spain, as well as some that are currently underway at the hands of ALSA and the Ctag (Galicia Automotive Technology Center). A pioneer regulation. Spain has been one of the first EU countries, together with Germany and Francein creating a clear legal framework for the circulation of autonomous vehicles in test phases. However, it is important to point out that the regulatory framework supervises pre-commercial phase operations, does not authorize the use of completely autonomous vehicles. In Spain, the autonomous circulation of levels 3 and 4 is not yet regulated, and in Europe it is taking its first steps in authorized trials and restricted areas. Outside Europe there is no clear consensus. In fact, Waymo has just announced his arrival from his taxis to New York … Operated with human supervisionsince state law still does not allow the operation open to traffic of a vehicle in a 100% autonomous way. Other cities, such as California, They allow robotaxis to be operated to which we have come to. Countries like China They have advanced to the United States in this race, with Baidu announcing that their service Apollo Go has completed 11 million tripsin front of the 10 million reported by Waymo. At the moment, the step taken by Spain is not a victory, but one of the most important advances to date in this area.

Apple does not know how to meet their environmental goals, so they have started planting trees crazy

The Big Tech are in the middle of a change. Not that of artificial intelligence –that too-but that of Achieve carbon neutrality. On this path to decarbonization with Objectives for 2030 and 2050Apple is one of the companies that have the most interest in users to know that they care about the environment. In fact, in the presentation event of the iPhone 15 and of Apple Watch Series 9being one of the most important technological events of the year, the company shared a Fun video. In it, their mandamases met with the representation of the Earth to inform about their progress in reducing emissions, the installation of Solar panels in California and the increase in recycled materials on its devices. But renewables are not enough to achieve those objectives, and Apple has made the decision to plant tens of thousands of trees. He is doing it in Brazil with the aim of reconverting grasslands in forests that catch carbon, but everything that shines is not gold. A two times bigger forest than Manhattan There is a trend among companies that we are seeing in recent years. To reduce carbon emissions, it is not enough to install more renewable, reduce the consumption in your data centers and optimize transport. In Fast Company We read that these actions are not enough to reach the objectives and that the secret is in the direct capture of CO₂ (and there are controversy about it about its effectiveness). We are seeing how there are companies that are investigating the creation of buildings that capture carbon dioxide, but also experiments to discover What kind of trees They are the ones who catch the most. Apple ha reduced Emissions in 60% compared to 2015 and expect to reach 75% of a 2030. The problem is to exceed that figure and reach 100% in the face of 2050. Chris Busch is the Director of Environmental Initiatives of Apple and comments that they do not have “a clear line of vision of how to avoid these broadcasts today.” It seems that they have reached a point where the use of renewables is not enough and you have to move on to a new approach. “And that’s where nature comes to play a role,” says Busch. In 2021, Apple destination 200 million dollars to a fund to help in the creation of environmental and carbon elimination projects, something for which it promised additional 200 million dollars in 2023. During these last two years, different associations with the support of this member of the Big Tech have replanted more than 10,000 hectares in an area southwest of Brazil. The idea is to reconvert areas for grazing and livestock in forests that not only recover trees to capture CO₂, but also the return of local fauna such as rabbits and pumas to an ecosystem that had been very damaged by other types of activities. It is an effort part of a major program that seeks to restore almost 300,000 hectares of degraded land in Brazil, Uruguay and Chile. Apple is not only helping financially, but also at the technological level. And, obviously, this is not selfless. “What we intend is to generate financial performance as a investor in these projects,” says Busch. This yield will be in the form of lower payments for their CO₂ emissions and the manager also comments that the global objective is shared. “We have to reduce emissions as soon as possible, but also put an end to deforestation and increase carbon elimination to maintain within 1.5 degrees”He said. And this is not just about planting trees. The Cupertino are technologically supporting project monitoring, such as the measurement of the trees’s trunk diameter, but they are not the only ones. Google, goal or Microsoft have also created coalitions To plant trees and compensate for their greenhouse gas emissions, and companies that are not within that select group also have reforestation initiatives. It is not planting by planting Now, you have to be careful with the type of trees that are planted in these reforestation programs. And with other factors. In Fast Company they point to a controversy in this concrete reforestation because they are planting eucalyptus. They are trees with potential to evolve in punished terrain, such as ancient animals for animals, and grow rapidly absorbing large amounts of co₂. The problem is that reforestation reduces rainfall and eucalyptus, precisely, need water, so critics point out that these plantations will do will end underground water reserves. Also Questionable actions have been produced. In Pakistan, mass reforestation programs came into conflict with the practices of nomadic communities, something that has also occurred in places in China or Brazil itself. We must not go so far: in Europe we are reforesting huge areas with trees that are suitable for that reforestation, but that They may not reach 2100. The reason? They are species that or are not native or, even if they are planting without taking into account possible future pests or the effects of climate change. Research has also been carried out that the effectiveness of these projects is limited. As they comment on The Guardianmost of these projects do not generate real climatic benefits and there are areas that are being reforested in which there was no real risk of deforestation. The point by which some actions have been undertaken is due to the overestimation of the emissions avoided. And the study does not point to 10 or 20% of these reforestation actions, but 90% of them. As much as it may be, planting trees is positive whenever it is done with the head, but as Forrest Fleishman, an expert in mass plantation of trees, rather than planting trees, must be made.
