It’s 9am on a hot August morning and timed tickets to visit Barcelona’s emblematic Sagrada Família basilica have already sold out. Only a few years ago you could turn up and queue for maybe half an hour to get in but with the soaring numbers of visitors to the city (around 30 million last year) anyone who arrives on spec is likely to be disappointed.
Those who have tickets amuse themselves in the queue by taking selfies in front of the temple’s ornate nativity facade. Groups of tourists trail behind their lollipop-waving guides. Street vendors spread out their wares on the pavement – pirated designer sunglasses and tacky memorabilia - until a heavily-armed police patrol moves them on. At the stalls around the square you can buy soft toys, Gaudí ashtrays and Barça scarves.
Antoni Gaudí’s masterpiece was begun in 1882 and is due for completion in 2026. The work was intended to be funded by penitent sinners – but there are more tourists than repenters around these days (it is the city’s most popular destination, with 4.5 million visitors in 2016), so tourists are footing the bill.

At Casa Batlló, Gaudí’s apartment building in the busy Passeig de Gràcia, the queue snakes around the corner, and this is the queue for people who have bought advance tickets at €28.50. They wait behind a sign that says “Skip the Line”. The woman at the door says the wait for people with tickets is around 20 minutes. After a pause she shrugs: “OK, perhaps more like 40.”
Barcelona remains a beautiful city, one of the most attractive in Europe, huddled between the mountains and the sea, with a wonderful climate and wealth of architecture and history.

It used to pride itself on the quality of its design and was dubbed the capital of cool in the late 20th century. It is far from cool now though, and a day traipsing around the tourist hotspots reveals how it has become the home of tat, with the magic word “Barcelona” printed on any old junk, from straw hats and teddy bears to beach towels and coffee mugs. Not to mention all manner of ceramic creatures made in Gaudí’s trencadís style of broken tiles.

  • La Rambla … Barcelona’s most famous street is now its epicentre of overtourism
La Rambla is Barcelona’s most famous street but for residents it became its least-loved long ago, so crowded as to be virtually impassable for nine months of the year.
From the moment it was created in the 18th century La Rambla became a place where the wealthy could flaunt their finery and the poor could hustle and everyone could breathe, outside the walls of the crowded mediaeval city. It was never chic, indeed, it was always slightly edgy and marginal – but now there is nothing but souvenir shops, interspersed by McDonald’s and shabby restaurants serving kebabs and paella a startling shade of chrome yellow.

At all hours, young men invite you sotto voce to a “coffee shop” à la Amsterdam. This is something new. At night there are prostitutes, which isn’t new, except now most of the women have been trafficked.
Last year a consortium was appointed to come up with a plan to attract residents back to La Rambla. They have consulted widely and details of the plan are expected to be published soon, but they have their work cut out.
“La Rambla is above all a business,” says Fermín Villar, president of the Friends of La Rambla, which represents the street’s residential and commercial interests. “Every year more than 100 million people walk along this street. Imagine, if each person spends only one euro.”
Itziar González, the architect who heads the symposium, says the first task is to convince people that La Rambla can be saved. “It’s not just about changing things,” she says, “it’s about changing minds.”

It’s doubtful, however, whether the Boqueria food market on La Rambla can be saved. Once a mecca for cooks and foodies where you could buy everything from truffles to edible insects, the stallholders are one by one caving in to the force majeure of tourism, with fresh fish, meat and vegetables giving way to juice bars and assorted takeaways. The very reason for visiting la Boqueria – even as a tourist – will soon cease to exist.

Barcelona is one of Europe’s most densely populated cities, with few open spaces. So when the seafront at Barceloneta was opened up in time for the 1992 Olympic Games it gave the city breathing space, just as La Rambla had two centuries earlier. It became the new place to pasear, the evening or Sunday stroll that is such a part of Spanish life.

But Barceloneta has become another no-go zone for residents as it has degenerated into a sort of urban Lloret de Mar. Lie on the crowded beach and every few minutes a vendor will offer you beer or water or a mojito, a massage, a henna tattoo and sometimes weed. Rickshaws ply the waterfront while shirtless young men whizz by on electric scooters.

The saddest thing about all this is the city is rapidly losing its identity and becoming like everywhere else. A new word has been coined to describe this apparently unstoppable process: parquetematización – the act of becoming a theme park. Barcelona has become an imitation of itself.

Since you’re here…

… we have a small favour to ask. More people are reading the Guardian than ever but advertising revenues across the media are falling fast. And unlike many news organisations, we haven’t put up a paywall – we want to keep our journalism as open as we can. So you can see why we need to ask for your help. The Guardian’s independent, investigative journalism takes a lot of time, money and hard work to produce. But we do it because we believe our perspective matters – because it might well be your perspective, too.
The Guardian is editorially independent, meaning we set our own agenda. Our journalism is free from commercial bias and not influenced by billionaire owners, politicians or shareholders. No one edits our Editor. No one steers our opinion. This is important because it enables us to give a voice to the voiceless, challenge the powerful and hold them to account. It’s what makes us different to so many others in the media, at a time when factual, honest reporting is critical.
If everyone who reads our reporting, who likes it, helps to support it, our future would be much more secure. For as little as £1, you can support the Guardian – and it only takes a minute. Thank you.

El dia del «sobregir»: quan la Terra ja no ens pot mantenir

Hem exhaurit els recursos naturals que el nostre planeta pot regenarar durant un any més aviat que mai

El dia del "sobregir" s'ha avançat. Ha estat més aviat que mai. El 1970 era el desembre, però cada vegada s'avança més. El 1992 va ser el 13 d'octubre i el 2000, l'u de novembre. Però entre el 2009 (25 de setembre) i el 2010 (21 d'agost) es va accelerar. I, enguany, s'ha avançat un dia: s'esperava el dos d'agost.

Som set mil cinc-cents milions de persones al món, només per això ja generem una enorme pressió sobre el planeta i sobre els altres animals amb qui el compartim. Amb la nostra presència i les nostres activitats, el planeta necessita més d'un any i mig per regenerar el que consumim en un any.

Hem exhaurit els recursos naturals que la Terra pot regenerar durant un any. Per suportar el nostre nivell de consum com actuem avui, necessitaríem 1,7 terres –segons dades de la Xarxa Global per la Petjada Ecològica (Global Footprint Network).

La Petjada Ecològica és un indicador que avalua l'impacte de la demanda de les nostres accions sobre la biosfera. Es mesura en "hectàrees globals". En dades de 2014, els tres primers llocs els ocupen la Xina (5.200 milions d'hectàrees globals i 1.400 milions d'habitants), Estats Units (2.670 milions d'hectàrees globals i 319 milions d'habitants) i l'Índia (1.450 milions d'hectàrees globals i 1.247 milions d'habitants). Espanya ocupa el lloc vint-i-u (176 milions d'hectàrees globals i 46,6 milions d'habitants).

L'empremta ecològica també es pot calcular per persona. El 2014, els habitants de Qatar van necessitar 15,7 hectàrees globals per càpita. A Espanya hem consumit 3,8 hectàrees globals (l'any anterior van ser 3,9, i el 2007 –abans de la crisi– gairebé 6!); és a dir, necessitem tres països com el nostre per a produir el que consumim i absorbir el que rebutgem. Les hectàrees globals requerides per habitant en els països mencionats abans són els Estats Units (9,9), La Xina (3,7) i l'Índia (1,1).

Només tenim un planeta, però consumim com si tinguéssim l'equivalent a més d'un i mig. Fem servir més recursos ecològics dels que la natura pot regenerar i emetent més diòxid de carboni a l'atmosfera que els ecosistemes poden absorbir. Cal reconsiderar la sobrepesca, la sobreexplotació dels boscos; si seguim així, el 2050 consumirem com si tinguéssim dos planetes i mig.

El punto de no retorno para llegar a un apocalipsis abrasador en la Tierra está cada vez más cerca, según un grupo de científicos

El punto de no retorno para llegar a un apocalipsis abrasador en la Tierra está cada vez más cerca. Eso es, al menos, lo que opina un grupo de científicos que se plantea un futuro en el que el cambio climático ha transformado nuestro planeta y ha hecho casi imposible la vida.
Lo llaman la "Tierra invernadero", un lugar en el que las temperaturas globales habrían aumentado en torno a los 4 ó 5 grados centígrados respecto a la era preindustrial y en el que el nivel de los océanos sería de entre 10 y 60 metros más alto que hoy en día, tal y como detallan en su artículo titulado Las 9 principales maneras del fin de la Tierra, publicado en la revista Proceedings of the National Academy of Sciences.
En ese escenario, que sitúan alrededor del año 2300, la climatología del planeta se habría vuelto más extrema, con huracanes capaces de arrancar rascacielos del suelo, y en el que las sequías y los incendios forestales durarían años enteros. De hecho, paradójicamente, el último refugio del ser humano serían los polos que hoy se derriten sin remisión.

Si la temperatura global aumenta dos grados podría significar un punto de no retorno

Aunque suene algo apocalíptico, lo cierto es que los efectos de un aumento global de las temperaturas son tan impredecibles como temibles.
Por eso, la Unión Europea al completo y 179 países en total firmaron en 2016 el Acuerdo de París, a través del cual se comprometieron a luchar contra el cambio climático y, en concreto, a impedir que la temperatura global suba por encima de los 2 grados centígrados respecto a los niveles preindustriales.
Una referencia de temperatura (2 grados centígrados) que para los científicos que firman el artículo puede significar un punto de no retorno en la Tierra hacia un futuro en el que el ecosistema natural del planeta sea incapaz de autorregularse y termine por convertir nuestra casa en un horno insoportable.
El problema es que, con la salida en 2017 de EE.UU. del tratado, el incumplimiento del mismo por parte de China en determinados aspectos y que de momento no hay evidencias de grandes avances en la disminución de las emisión de carbono, parece que la raza humana está condenada a presenciar los efectos de su participación en el cambio climático.

La evidencia de la acción humana en el cambio climático

Por increíble que parezca, hasta hace relativamente poco no se ha producido un consenso científico respecto a la implicación del ser humano en la aceleración del cambio climático.
Se debe, principalmente, a que la época en la que vivimos ─llamada Holoceno─ representa un período natural de desglaciación en la Tierra. Esto significa que desde hace 12.000 años aproximadamente nuestro planeta ha iniciado un ciclo cálido que ha sucedido a la anterior glaciación, conocida comúnmente como edad de hielo.
Estos ciclos se llevan produciendo desde los inicios de los tiempos de forma natural, independientemente de la acción humana. Sin embargo, las evidencias científicas respecto al aumento de las temperaturas globales en los últimos 150 años, el aumento del nivel del mar y la desaparición de especies animales y vegetales, han terminado por constatar los efectos de la acción humana en ese cambio climático natural.
Las emisiones de carbono, las de gases de efecto invernadero, la destrucción de la capa de ozono ─que, a pesar de su reciente mejoría, sigue suponiendo un peligro, especialmente en el Antártico─ o la contaminación de los océanos son algunas de esas acciones que están transformando la Tierra, tal y como denuncia Greenpeace.
Por eso, algunos efectos ya visibles como la rápida deforestación de algunos países tradicionalmente verdes, como en el caso de España, empiezan a preocupar seriamente a la comunidad científica, la cual continúa advirtiendo sobre las consecuencias catastróficas de no cambiar nuestro estilo de vida consumista. Por suerte, aún estamos a tiempo.
