It is not strange that in December talk about lights. In recent years some cities in Spain have launched a crazy race for displaying millions of LEDs along its streets or raising the tallest luminous Christmas tree in the country. What is less common is that people talk about the lights that decorate the bed of a river, which is precisely what has been worrying environmentalists and residents of Madrid for days. To be more precise it worries them the City Council’s initiative to activate 61 projectors in Manzanares.
For the City Council, these lights are a success that will “more attractive” the riverbank and will reinforce its security. For neighbors and environmentalists, it is a mistake that will generate something very different: “light pollution.”
What has happened? That Manzanares is news. And not because of the “renaturalization” process that began years ago, of which they stick out their chest the Madrid City Council and the neighbors and (among other things) has helped recover its fauna.
The key in this case is quite different: the lighting system installed in a 560-meter stretch of the river, around Dam 6, between the districts of Arganzuela and Latina. Although the spotlights were installed there more than a year ago They were not activated until a few days agocoinciding with the on of Christmas lights. The problem is that what for the City Council is a cause for celebration for residents and environmentalists is a problem.
Why’s that? Because the opinions regarding the Manzanares lights could not be more different. If you ask the City Council, it is an initiative “sustainable and respectful” with the environment that will benefit the neighbors and attract tourists. “It will make this city environment more attractive for residents and visitors, also offering more security to pedestrians,” claims José Luis Martínez-Almeida’s team in the statement in which he celebrated the commissioning of the lights, last Saturday the 22nd.
“The 61 LED projectors will project a blue light to boost the attractiveness of the area and realize the central construction,” abounds the City Council before stating that the lights are part of a “pilot project” and are here to stay. For now, they will continue to operate beyond Christmas, on Fridays, Saturdays and Sundays, adapting their operating hours to sunset.
What do the critics say? They talk about “light pollution” and a measure that has been deployed “despite citizen and scientific rejection.” Among those who have spoken out most vigorously against the 61 river projectors are: Ecologists in Action and the Corridor Verde-Imperial Neighborhood Associationgroups that put forward various arguments, such as that the new outbreaks will negatively affect the ecosystem or that they only seek to attract visitors.
“It is unnecessary and harmful, it is not justified by any reason of general or public interest and it only responds to the arbitrary whim of the City Council in its desire to continue touristifying the city in general and Madrid Río in particular”, regrets Ecologists. However, the greatest emphasis is placed on the impact that LEDs will have on fauna, something that has already earned them “scientific rejection.”
Will it affect the river ecosystem? It depends on who you ask. For the environmental group there are no doubts. “You cannot subject the fauna of Manzanares to an eternal day, not only the birds, but also the insects, which are a crucial part of the ecosystem,” warns in The Confidential Erika González, biologist.
“Fauna, like human beings, also need darkness for their life cycle (…) It is difficult for us to understand why the City Council, the same one that decided to successfully renaturalize Manzanares and dedicates a budget for maintenance, now decides to attack the ecosystem.”
Things are quite different for the local government, which in the same statement in which he reports on the switching on of the projectors, he emphasizes that the system has been designed applying environmental criteria. “It has been developed using solutions that minimize light pollution. The spotlights are located in a pocket of the river, limiting light emissions to the sky.”
Is it the only disagreement? No. Another idea in which the City Council and the neighbors clash is the convenience and necessity of the lights. From the City Hall they argue that the lights will improve “safety” around the river, but residents question whether that is necessary. “There is no insecurity problem and if there were, the logical thing is that lights be installed on the street, not in the river bed,” reasons Susana de la Higuera, from the Pasillo Verde-Imperial Neighborhood Association.
The controversy surrounding the Manzanares lights dates back a few months. In fact, the City Council installed them in 2024 with a view to Christmas of that year, but his critics took the issue to the courts and requested precautionary measures. Although the process is not resolved, the judge handling it denied a few months ago the temporary stay that kept the lights disconnected.
Ecologists in Action regrets In any case, the City Council has turned them on with the contentious appeal still open. Their discomfort (like that of the neighbors) has already moved to the street with a protest on friday.
