    EU external borders : Irregular crossings drop by 20% in first 5 months of 2025

    https://visionscarto.neocities.org/00-images-seenthis-CDB/IBC_simplified_2025_05.prop_750x.8ee421b87a.png

    Irregular border crossings into the European Union dropped by 20% in the first five months of 2025, totalling 63 700, according to preliminary data collected by Frontex*.

    With over 3 300 officers stationed along the EU’s external borders Frontex is working together with national authorities to safeguard borders and save lives at sea.

    Key Highlights:

    - Central Mediterranean remains the busiest route this year, accounting for one of every three arrivals into the EU.

    - Western Balkans sees the steepest decline in arrivals between January and May (-56%).

    - Most frequently reported nationalities: Bangladeshi, Afghan, and Malian.

    In the Central Mediterranean, 22 700 irregular crossings were recorded in the first five months of 2025, reflecting a slight increase (+7%) compared to the same period last year.

    Libya remains the main country of exit for migrants on this route, with a significant increase this year offsetting an almost 90% decline in departures from Tunisia, as the Tunisian authorities are stepping up their efforts to curb irregular migration.

    The Eastern Mediterranean was the second most active route in January-May, with 15 600 irregular crossings, representing a 30% drop compared to 2024.

    On the Western African route, the number of arrivals fell by a third to almost 11 100. The main nationalities on this corridor were Malian, Senegalese and Guinean.

    This significant drop can be attributed to multiple factors: stronger border controls and migration policies in Mauritania, poor weather conditions, and enhanced cooperation between the EU and countries of departure. Joint Spanish-Moroccan patrols have also played a key role in disrupting smuggling activities near the Canary Islands.

    Many risk their lives to reach Europe, embarking on the perilous journey across the Mediterranean in unseaworthy boats. The International Organization for Migration estimates that in just the first five months of this year alone, 651 people lost their lives at sea.

    On the Channel route, the number of migrants attempting to cross into the United Kingdom increased by 17% compared to last year to 25 540.

    Recent months have seen an uptick in Channel crossings. Smuggling networks operating in the area are adapting, using simultaneous departures to increase the number of successful crossings. This tactic puts more lives at risk in an already dangerous stretch of water as it hinders the search and rescue efforts of the national authorities.

    The City and the City and the City

    https://visionscarto.neocities.org/00-images-seenthis-CDB/dalal-12-city.jpg

    A mapping workshop with refugees from Homs, Syria, illuminates the complexity of rebuilding after war.

    https://visionscarto.neocities.org/00-images-seenthis-CDB/dalal-13-city-1536x1060.jpg https://visionscarto.neocities.org/00-images-seenthis-CDB/dalal-15-city.jpg

    “Homs was a very beautiful city,” said an older man, nicely dressed in a blazer and white shirt. He had left Syria for Berlin in the 1990s, two decades before I did. At tables around the room, my colleagues sat with others who had fled violence. As music by the Lebanese singer Fairuz played in the background, this man remembered the canals, the palm trees on Ghouta street, the rhythmic sound of the New Clock Tower, the cannon stuffed with clothes that announced the breaking of the fast in Ramadan. Memories poured forth, generating an image of the city that was recognizable, but different from the one I grew up in. I mapped the stories he told.

    This was 2017, and the Syrian civil war was in its seventh year. Neither his Homs nor mine existed any longer. The last rebel neighborhood had been evacuated, and the city was controlled by Bashar al-Assad’s forces. Large areas had been leveled by mortar shells, and there were mass graves amid the rubble. In Berlin, I met with refugees to record memories of the city they had left behind. I wanted to understand how loss and trauma shaped their perceptions.

    In 2024, the war ended abruptly with the collapse of al-Assad’s government. Transition leaders now talk of reconstruction. But whose Homs do they want to rebuild? As I listen to architects and planners imagine the future, I remember the lessons of that mapping workshop. Which spatial claims have power? Whose visions of the city will be realized? These questions form the foundation of urban studies, but in Syria for more than a half century they were not discussed.

    Now we face the impossible challenge of reconstituting a country without understanding the different worldviews — indeed the different spatial realities — inhabited by the many sects and social groups. If we do not acknowledge these differences, we risk repeating the injustices that led to war in the first place.

    Under the Assad regime (father and son) that ruled Syria starting in 1971, analysis of the social composition of cities was forbidden. Any research or documentary project would need official permission that could not be obtained. Simply asking the wrong questions could lead to imprisonment. Knowledge was something to be feared. The city grew rapidly during this period, and the population tripled, but many residents — new and old — did not have a strong sense of its cultural geography outside the borders of their own experience. We lived together, but we did not see the city through one another’s eyes.

    At the start of the war, Homs was the third largest city in Syria, home to about 800,000 people. In my mind’s map, 1 there is an Old City in the center inhabited by a Sunni majority and some Christians living near the covered market streets. To the west is an affluent district planned during the French Mandate after World War I, inhabited mostly by Sunni urban elites. And west of that is the wide valley of the Orontes River, where I grew up, in a neighborhood of apartment buildings established in the 1980s, with a mixed, working-class population. Directly north of the Old City, a public square connects the “Old Clock” at the edge of the market with the “New Clock,” donated by an expatriate who moved to Brazil. Known for its cubic form and white-and-black stone cladding — imitating the city’s traditional architecture — the New Clock is a widely recognized symbol of Homs, the center of our shared geography.

    East of the center things get hazy. A 1943 map shows the urban development of east Homs contained to a one-kilometer band between the Old City and the historic mosque Khaled Ibn Al-Waleed. Sometime later in the century, under the Assad regime, the land around the villages of Zaidal and Fairuza filled in, sometimes haphazardly, with Alawaite migrants from the coast and Christians and Sunnis from rural areas. A United Nations report found twelve informal settlements occupying 59 percent of the city’s area. 2 The Sunni elites who lived west of the center did not have detailed knowledge of this new geography, but they understood the Alawites as a threat to their sovereignty — a sectarian division planned and enforced by the regime. 3

    In the years leading up to the war, and perhaps a precipitating cause of it, this threat materialized in the form of a neoliberal urban development project known as “The Dream of Homs.” In 2007, Mayor Eyad Ghazal announced his intention to spur economic growth through flagship architecture, similar to the reconstruction of Beirut’s Central District in the 1990s or Amman’s Abdali in the 2000s. 4 Eventually, the “Dream” morphed into a Haussmannian effort to beautify main streets and remake parts of the inner city without the involvement or consent of Sunni and Christian merchants, who would be evicted so that buildings could be demolished and the street plan rewritten. (As a recent graduate in architecture and urban planning, I joined a transnational office that worked on adjacent projects, including an ecotourism plan for Palmyra and public parks in Homs.)

    The few community meetings to discuss this plan did not allay the sense of injustice among people in the city center, and thousands gathered around the New Clock to call for an end to the Assad regime. 5 Later, when violence broke out, government forces targeted the urban poor in Sunni parts of Homs, leaving migrant neighborhoods alone. 6 Half of the city was destroyed and half of its people displaced. The plan to rewrite the streets of the Old City was unfinished, but the evacuation of its people was complete.

    Over more than a decade of war, 14 million refugees fled the country or were internally displaced. By 2020, at least 800,000 Syrians were living in Germany, including about 60,000 in Berlin. 7

    Sixteen men showed up to the Homs mapping workshop in 2017, the first in a series that I helped organize as a doctoral student. 8 We began by talking about prints of the city’s famous landmarks and spaces — the Old and New Clock Towers, the Citadel, the Khaled Ibn al-Waleed mosque, the City Center building, al-Hamediyyah Souq. We paired the participants by how close they had lived back home, and we found that most were Sunni from areas near the Old City or in west Homs. They did not know one another, or at least not well. We asked each pair to draw a map of their neighborhood as they remembered it, bridging the space between their two residences.

    Later, these maps were shared with the larger group. One pair, an older and a younger man, with different generational perspectives, presented their work. A third man interrupted, eagerly: “So, where were the military checkpoints located?” It must have been liberating to discuss something we could not speak about openly in Syria. “Here!” came the answer. “I drew eyes on the Military Security Building because they are watching us!”

    In another exercise, my colleagues and I spread out a blank writing surface, larger than one square meter. At the center we placed a drawing of the New Clock Tower. We asked the participants, “Starting from the Clock Tower, what do you remember of Homs? Can you re-draw the city from memory?” This was a difficult question to ask this group; some of the men were children when they left home. We encouraged everyone to draw and write freely, without holding back.

    The center of the map was a contested place. Some participants argued about the location of features. “No, no, this was here.” “Are you sure?” Others confidently drew the corners of the city they knew best, adding personal memories. “I had my first kiss here.” “My father died with a missile here.” “From here they [the military] dragged me like a dog.”

    Syria is known for its mosaic of ethnic and religious groups, which makes its cities culturally rich but also challenging to govern. During the workshop, I asked a colleague to draw a map of the sectarian composition of Homs neighborhoods. A few days later she sent a map marked up with colored hatches but no legend. Her voicemail was nonsensical: “Red is us, you know. Yellow is them. Blue are our friends,” and so on. I struggled to decode it, even as somebody who grew up there.

    The strategy of the Assad regime was to prohibit the expression of social identities, and to use urban planning to enforce the domination, control, or marginalization of certain groups, before and during the war. 9 People were allowed to say what sect they belonged to or where they lived, but they did not discuss how their identities impacted urban space and the built environment. 10 So this workshop was the first time many of the participants had compared their experiences or perceptions with others. Nobody had intimate knowledge of the informal settlements that made up the majority of the city’s land, and they left those areas unmapped.

    Toward the end of the day, we gathered around a satellite image of Homs, one that included those settlements, and we asked participants to place colored stickers indicating their emotions. One man added many dots to an area in the far west that seemed empty, so I asked him about it. “There is a Shi’a village here,” he said, “and they helped al-Assad in the war, so they deserve a black dot.” Although he was wrong about the location of the village, his anger was an undeniable fact.

    Resentments like this contradict the false ideal of national unity that was enforced in the old Syria, and that is too easily assumed as officials plan its reconstruction. “One, one, one. We are all one,” I heard protestors chanting in Berlin, on the day the Assad regime collapsed. Even architects and planners — people deeply attuned to the built environment — do not recognize the fractures in the pluralist city. They are trained to ignore those fractures, perhaps believing that doing so serves a greater good. But the sectarian divisions are real.

    I remember a Sunni friend feeling afraid as we entered a restaurant in an Alawite area in east Homs. “Who are these people, and why are they dressed like that?” he said. The rest of us laughed at his discomfort, but now I see in this memory a warning of the violence that would overtake the country.

    In Beirut, I interviewed a middle-aged Alawite man, who told me, “Of course I remember Homs. … Our dad used to take us to the souq in the Old City. When we’d walk there, people would laugh at us and treat us badly. They always considered us outsiders and villagers. They would say, Who are these people who are coming to our city?”

    Scars like these need to be addressed before Homs can be rebuilt, which means the reconstruction cannot be led by designers alone. We will need the involvement of historians, sociologists, anthropologists, political scientists, ecologists, and tradespeople and homemakers of every kind. We will need to make space for memorials and reconciliation efforts that recognize the places where people were oppressed, mistreated, and stigmatized.

    In June 2025, a billboard went up in the center of Homs, promising a grand urban reconstruction project, “The Boulevard of Victory.” It appeared to be a residential complex on destroyed land. 11 But who owned that space? And who had the right to reinscribe it? Public spaces, infrastructures, and cultural landmarks do not belong to one group alone. They are interwoven with the lives and losses of Sunnis, Alawites, Christians, Shi’a, Druze, Kurds, Ismailis, Yazidis, Palestinians, Bedouins, and others who built and inhabited the city across generations and were part of the city-making processes. A just and inclusive reconstruction must confront the sectarian and class-based ruptures that the old urban form helped conceal.

    A few weeks ago, the Boulevard project was cancelled — a hopeful sign for the future. 12 Rebuilding in a way that is just and inclusive will be a slow process that starts with sharing our memories and perceptions of the city and the way we lived within it. This is not compatible with a neoliberal planning model that recognizes only economic growth. 13 We have to learn to see the city in the ways that others see it, drawing maps and inviting others to draw with us, starting from the places we know best and filling in the spaces between, through careful negotiation. The physical rebuilding cannot go at a faster pace than the social reconciliation, or we will be hardening lines that lead to further violence and grief.

    How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
    ▻https://laurenleek.substack.com/p/how-google-maps-quietly-allocates

    https://substackcdn.com/image/fetch/$s_!sPnJ!,w_1200,h_600,c_fill,f_jpg,q_auto:good,fl_progressive:steep,g_auto/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F65709628-04f8-4288-b0c0-7f933fab17c3_1893x753.png

    London’s restaurant scene is no longer organised by taste alone. It is organised by visibility that compounds, rent that rises when discovery arrives, and algorithms that allocate attention long before consumers ever show up. What looks like “choice” is increasingly the downstream effect of ranking systems.

    For policy, that shifts the frame. If discovery now shapes small-business survival, then competition, fairness, and urban regeneration can no longer ignore platform ranking systems. Councils can rebuild streets and liberalise licensing all they like - but algorithmic invisibility can still leave places economically stranded. Platform transparency and auditability are no longer niche tech debates; they are quietly becoming tools of local economic policy. At minimum, ranking algorithms with this much economic consequence should be auditable. We audit financial markets. We should audit attention markets too.

    Squaring the nation - two strange Hungarian cartograms from 1902
    The first equal square mosaic tile maps.
    Attila Bátorfy
    Dec 08, 2025

    This article was originally published in IMCoS Map Journal in 2023. Republished with permission. Recommended citing: Bátorfy, Attila 2023. “Squaring the Nation: Two Strange Hungarian Cartograms from 1902.” IMCoS Map Journal No. 172 (March 2023), pp. 6–15. This online version contains a few minor changes and a new paragraph at the end.

    Two of the twenty-two map appendices in Pál Balogh’s book A népfajok Magyarországon (The Ethnic Species of Hungary), published in 19021, which runs to more than one thousand and thirteen pages, are remarkable for the way they present the ethnicities and religions of Hungary (Figs 1ab & 2). The graphic method used to produce them is variously known as as equal square/area grid map, or tilegram, or mosaic map, and it has been suggested that they may be the first examples of maps employing this method2. The two maps, designed by Pál Balogh and drawn by Sándor Kocsárd Proff are well known in Hungarian map history, especially within ethnic cartography.3 Balogh’s work is also a frequently cited source in the Hungarian historical demographic literature. But the now popular method of the maps4 or ‘anamorphic cartograms’5 is worth a closer look.

    Who was the forgotten artist and theorist Emily Noyes Vanderpoel? - South London Gallery
    ▻https://www.southlondongallery.org/journal/who-was-the-forgotten-artist-and-theorist-emily-noyes-vanderpoel

    https://www.southlondongallery.org/wp-content/uploads/2025/11/color-problems.jpg

    In 1902, American artist and writer Emily Noyes Vanderpoel published Color Problems: A Practical Manual for the Lay Student of Color. This surprisingly modern book, given the date it was published, combines science with art. Vanderpoel used gridded diagrams to analyse the colour composition of everyday objects, from ceramics and carpets to flowers and paintings. Each study broke its subject into a structured, geometric form. The results look shockingly similar to modern abstraction and contemporary data visualisation. Despite being made decades before, her work reminds us of Piet Mondrian and Josef Albers.

    Entre les cartes mentales réalisées par des élèves et les chorèmes hérités de la géographie structuraliste, il semble n’y avoir aucun pont possible : d’un côté le vécu, l’intime, l’esquisse hésitante ; de l’autre, le modèle, la structure, l’abstraction.

    L’Atlante italiano dei morti e feriti gravi in bicicletta. Perché gli “scontri” non sono numeri

    https://craft.dastu.polimi.it/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6ODA4LCJwdXIiOiJibG9iX2lkIn19--37dbd6657c9e486dbf1104c422acbc5ef24fdf0a/Screenshot%202025-09-04%20alle%2014.55.58.png?locale=it

    Nell’incidente stradale si conosce quando la macchina è stata immatricolata, la cilindrata, chi guidava e dove. Delle collisioni in bicicletta, invece, non si sa praticamente nulla. Il progetto di ricerca curato dal Politecnico di Milano colma per la prima volta questo vuoto, mappando la diffusione e la gravità degli incidenti in bici in Regioni, Province e città. Ne abbiamo parlato con gli autori.

    Dal 2014 al 2023 in Italia ci sono stati un milione e mezzo di incidenti stradali totali, di cui più di 160.000 hanno coinvolto persone in bicicletta. Ma tutto questo non può rimanere “solo” una fredda statistica. Ecco perché il Centro di competenze territori antifragili (Craft) del Dipartimento DAStU del Politecnico di Milano, ha deciso di analizzare e indagare in modo specifico e approfondito gli eventi, a partire dalla totalità dei dati sugli incidenti stradali pubblicati ogni anno dall’Istituto nazionale di statistica (Istat). Dando così corpo all’Atlante italiano dei morti e feriti gravi in bicicletta.

    Il gruppo di ricerca coordinato dal professor Paolo Bozzuto, e formato da Emilio Guastamacchia, Fabio Manfredini e Shidsa Zarei, ha pubblicato infatti a ottobre 2025 la più dettagliata mappatura dell’incidentalità ciclistica mai realizzata in Italia, sintetizzata in cinque dashboard consultabili gratuitamente sul sito del Politecnico, per osservare la consistenza e la distribuzione geografica degli incidenti e dei loro livelli di gravità e mortalità nelle città, Province e Regioni italiane.

    L’idea è nata alla fine del 2022 dopo la morte di Davide Rebellin, ciclista professionista travolto da un camion in provincia di Vicenza. Nello stesso anno gli incidenti in bici sono stati 17.065 e le manifestazioni per ricordare le vittime sono aumentate.

    Dalle mappe interattive emerge che, a livello regionale, tra il 2014 e il 2023 il numero più elevato di incidenti in bici si è registrato in Lombardia (41.502), Emilia-Romagna (30.447), Veneto (23.139) e Toscana (16.472). Nelle città il podio è detenuto da Milano (10.372), Roma (3.457) e Padova (3.132). Tuttavia, come ricorda ad Altreconomia Emilio Guastamacchia, co-autore della ricerca, “che ci siano tanti incidenti in valore assoluto, come in questo caso, non vuol dire che la Regione è la peggiore, perché probabilmente è anche il territorio in cui c’è più popolazione che si muove in bicicletta”.

    Osservando quindi l’incidentalità ciclistica e la quota modale, cioè la percentuale di viaggi effettuati con un certo mezzo di trasporto sul totale dei viaggi, emerge che nel 2022 le Regioni dove si utilizza maggiormente la bici sono Trentino-Alto Adige (7,25%), Veneto (6,63%) ed Emilia-Romagna (6,25%). A specchio, l’incidentalità ciclistica (percentuale di scontri che coinvolgono biciclette sul totale degli incidenti stradali) è più alta in Trentino (18,81%), Emilia-Romagna (18,56%) e Veneto (18,15%). Con questi dati la Lombardia è quarta, con una quota modale di spostamenti in bici pari al 4,32% e un’incidentalità ciclistica del 14,44%.

    Anche il numero dei morti è più alto nel Nord Italia, dove la bicicletta si utilizza di più. Tuttavia il tasso di mortalità, ovvero il rapporto tra il numero di ciclisti morti e il numero di incidenti ciclistici, si concentra nelle Regioni del Sud e nello specifico in Calabria, Molise, Campania e Basilicata. “Significa che ci sono più incidenti al Nord ma il livello di pericolosità è più concentrato al Sud. Questo -spiega Guastamacchia- può essere probabilmente dovuto all’assenza di infrastrutture ciclabili. Al Nord, tutto sommato, la presenza di piste ciclabili, anche se progettate male o non a rete, mette più in sicurezza il ciclista”.

    Oltre ai filtri geografici, le mappe dell’Atlante permettono di selezionare il genere delle persone coinvolte negli incidenti e, in alcuni casi, anche la loro età e l’orario in cui sono avvenuti gli scontri.

    Nell’incidente stradale si conosce quando la macchina è stata immatricolata, quale cilindrata possiede, chi guidava e dove si trovava. Delle collisioni in bicicletta, invece, non si sa praticamente nulla. Gli unici dati che Istat fornisce sono l’orario dell’impatto e se si tratta di una bicicletta normale o a pedalata assistita. “Mancano però informazioni più puntuali -fa notare il ricercatore-, in che condizioni di manutenzione si trovava il mezzo, un conto è guidare una bicicletta con un impianto frenante e un conto è andare con una che non ha i freni; qual era il motivo dello spostamento, professionale, turistico o per uso quotidiano. Questi dati, che ad oggi Istat non fornisce, permetterebbero una lettura più fine del fenomeno, che potrebbe aiutare anche a pianificare interventi infrastrutturali per rendere la viabilità più sicura”.

    Conoscere gli orari in cui avviene la maggior parte degli incidenti, sulla base territoriale, permette comunque di iniziare un lavoro di “radiografia” del ciclista perché dà delle informazioni su quando viene utilizzata la bici. Nel caso della provincia di Cremona, per esempio, il livello degli incidenti è molto diffuso in settimana e nel corso dell’intera giornata; quindi, è ipotizzabile che si tratti di lavoratori e city user. A Milano è particolarmente elevato negli orari di punta, al mattino e alla sera. Nel caso della provincia di Lecco, al contrario, si rileva una connotazione più turistica, con incidenti meno distribuiti durante la settimana e più concentrati il sabato mattina.

    “Oggi quello che possiamo dire è che la maggior parte degli incidenti avviene in ambito urbano piuttosto che extraurbano. Sicuramente questo è perché in città ci si muove di più. Tuttavia, l’incidente in bici che avviene fuori dalle città è più pericoloso, nel senso che ha degli esiti più gravi. Questo ci suggerisce che, essendo la velocità media nelle zone extraurbane maggiore di quella urbana, una delle questioni su cui lavorare è sicuramente quella della velocità di percorrenza delle strade. Più si riduce la velocità, più ci sono possibilità di abbassare il tasso di incidentalità ciclistica e pedonale -aggiunge il ricercatore-. Il caso del Comune di Bologna, che un anno fa ha imposto in ambito urbano la velocità massima di 30 chilometri all’ora, ha ridotto in modo significativo il numero di incidenti complessivo. Questo è un tema da cui partire”.

    Come conferma Guastamacchia, questi primi dati della ricerca sono l’inizio di un lavoro più ampio che i ricercatori del Craft continueranno a portare avanti con nuovi indicatori per avere più informazioni da mettere a disposizione dei cittadini e per la pianificazione di possibili soluzioni urbane. Un cambiamento necessario però deve avvenire anche a livello culturale. Alla pubblicazione delle cinque dashboard dell’Atlante, sulle pagine social del Politecnico sono apparsi commenti violenti come: “La prossima volta che vedo un ciclista lo metto sotto”.

    In città come Milano l’automobile privata è ancora tra le modalità privilegiate di trasporto: il 30% degli spostamenti interni alla città avviene in macchina, mentre solo il 6% in bicicletta.

    Per il momento -commenta Guastamacchia- la reazione che la ricerca sta ricevendo proviene principalmente dal basso, da associazioni o singoli utenti interessati a capire il fenomeno. “Dalle istituzioni c’è stato qualche primo contatto ma non in modo strutturato”.

    Intanto la mobilitazione di associazioni e cittadini che hanno aderito alla campagna di Città delle persone continua. Con la loro lettera aperta hanno chiesto al sindaco di Milano una rete di infrastrutture ciclabili continue e sicure, denunciando che ad oggi il 22% di quelle dichiarate sono controviali promiscui dove non è stato fatto alcun intervento strutturale; un aumento quantitativo e qualitativo del trasporto pubblico e una maggiore intolleranza nei confronti della sosta irregolare.

    “Il lavoro del Politecnico di Milano va nella direzione della messa a disposizione di maggiori dati e informazioni su questo fenomeno, ma le domande aperte rimangono tante e il percorso, purtroppo, è ancora lungo -commenta Giovanni Mandelli, portavoce di Città delle persone-. Noi lavoriamo principalmente a Milano dove ci sono ancora troppe automobili e velocità elevate, se compariamo il tasso di motorizzazione e il limite di velocità di altre grandi città europee. La domanda da porsi allora è: vogliamo vivere in una città dove lo spazio pubblico è progettato per le persone o per le automobili? E nel caso delle bici penso che sia fuorviante utilizzare la parola ‘incidente’ perché questa allude a circostanze incontrollabili. Invece, sappiamo tutti che stiamo parlando di eventi che avvengono regolarmente e che sono imputabili a precisi comportamenti scorretti e pericolosi: distrazione, eccesso di velocità, guida in stato alterato. Non incidenti ma ‘scontri stradali’”.

      La ricerca mira ad approfondire la conoscenza sul fenomeno dell’incidentalità ciclistica, indagando i fattori di rischio e le molteplici criticità (condizioni spaziali, dotazioni infrastrutturali, pratiche d’uso della strada, ecc.) che, nei contesti metropolitani, urbani ed extraurbani italiani continuano a causare morti e feriti tra le persone che decidono di impiegare il mezzo a pedali per una molteplicità di pratiche d’uso della città e del territorio: dagli spostamenti sistematici, allo svago, allo sport (amatoriale e agonistico).
      La percezione diffusa di un rischio evidente nell’uso della bicicletta lungo le strade italiane – e la conseguente scarsa propensione all’uso del mezzo a pedali da parte delle persone – costituisce uno dei principali fattori critici che oggi minano radicalmente le prospettive di sviluppo della mobilità attiva (e sostenibile) in Italia.

    Mapmen »We are the men, and here is the map!«

    Die Karten lügen nie. Außer natürlich, es sind Landkarten. Dann lügen sie immer. Mindestens ein bisschen, etwa bei der Straßenführung (wer schon einmal in einem Sumpf feststeckte, von dem die Karte hartnäckig behauptete, hier verlaufe ein gut ausgebauter Wanderweg, kennt das). Oft etwas mehr, etwa bei der Lage oder Größe von Ländern (dazu hat Frankreich einiges zu erzählen). Und gelegentlich werden auch Staaten oder ganze Kontinente einfach erfunden – oder verschwinden im Nirwana. Für die beiden Geographieenthusiasten Jay Foreman und Mark Cooper-Jones stets ein gefundenes Fressen, das sie als »Map Men« mit Leidenschaft und einer Riesenportion britischen Humors in kurzen Videos auf Youtube verwursten (englischsprachig). Seit Mitte September läuft bereits die fünfte Staffel. Ganz aktuell gibt es das Ganze auch sehr unterhaltsam in Buchform – »This Way Up: When Maps Go Wrong (And Why It Matters)« –, aber an die Sketche kommt der 384-Seiten-Klopper natürlich nicht ran.

    Pixel prison

    ▻https://www.visionscarto.net/pixel-prison

    Texte et photos : Richard Pereira de Moura, géographe

    Les espaces carcéraux ont longtemps échappé aux études géographiques, qui se sont beaucoup plus intéressées à leur répartition qu’à leurs spatialités internes. Ce projet s’inscrit dans une approche élargie de la cartographie appréhendée à travers le prisme des arts visuels : non plus comme outil de représentation ou d’analyse, mais comme expérience sensible, critique et narrative des
    espaces.

    Si la géographie est l’étude des espaces habités, la prison en est à l’évidence un terrain d’exploration privilégié. Quiconque expérimente la détention — qu’il s’agisse du détenu, du visiteur, du fonctionnaire ou, dans mon cas, de l’artiste intervenant en détention — ne peut ignorer, à des degrés évidemment divers, le poids de l’espace architectural et géographique sur le corps et l’imaginaire.

    The Strange History of Why North Is Always Up
    Published: Oct 26, 2025written by Juan Sebastián Gómez-García, MA in Dance Knowledge, Practice and Heritage

    South-up maps are challenging traditional views of the Earth—and the political and cultural beliefs that go with them.
    Inverted world map with globe alongside it

    For centuries, world maps have been designed under a widely accepted spatial convention: the “north” goes up, and the “south” goes down. With this perspective largely uncontested, imagining other ways of representing the world might seem irrational or even unscientific. Yet, unquestionable trust in how the world is taught is a barrier to understanding that the purportedly objective activity of map-making has long been influenced by different historical and cultural conjunctures and undertaken for specific geopolitical purposes.

    Nos cartes personnelles

    Une réflexion sur la cartographie sensible, ou expérientielle offerte par The Times of India

    ▻https://timesofindia.indiatimes.com/the-maps-our-lives/articleshowprint/124821506.cms

    N’y a-t-il pas quelque chose de magnifique dans une carte ? Souvenez-vous du plaisir d’ouvrir un grand atlas de « cartographie traditionnelle » et de contempler ses splendides représentations de la Terre : d’immenses continents au milieu d’océans bleus tourbillonnants, des États-nations aux frontières précises, des montagnes majestueuses, de vastes déserts, des enchevêtrements denses de jungle, des îles grandes comme des mouchoirs, reliées entre elles par des réseaux commerciaux, de chemins de fer, de lignes aériennes et maritimes, jusqu’aux tracés du transport public qui nous mènent vers (et depuis) les lieux d’activité.

    Ces cartes révèlent aussi d’immenses richesses terrestres : là où se trouvent les diamants, l’or et l’argent, quels pays cultivent le blé doré et ondoyant, quelles strates géologique recèlent le pétrole, le charbon ou la tourbe — et qui en a le contrôle.

    Mais à quoi ressemblerait votre propre carte ? la carte qui raconte votre propre vie ? Que traceriez-vous sur ses axes ? le lieu où vous êtes né, l’école que vous avez fréquentée, le grand arbre sur lequel vous grimpiez, le trajet de bus vers l’université, votre trajet quotidien vers le travail, votre dispensaire et votre club, les maisons de vos amis, vos magasins préférés, voire les endroits risqués que vous évitez soigneusement ?

    La cartographie traditionnelle, élaborée au fil des siècles à mesure que le colonialisme se développait (et pour le servir), avide de toujours plus de sources de capital à exploiter, reste grandiose, mais elle passe à côté des aspects ordinaires de nos vies.

    Et cela est important au-delà de la seule émotion : car nos existences sont en réalité tramées et quadrillées selon des histoires dont beaucoup sont encore bien vivantes. Pensez à la manière dont des millions de personnes communiquent en anglais dans le monde entier, utilisent le dollar, exploitent les combustibles fossiles et perpétuent sans y penser le spécisme et l’extraction des ressources.

    C’est que nos vies ont été cartographiées par ces processus plus vastes et plus profonds, qui se sont entremêlés à nos cultures et à nos visions du monde, ouvrant une nouvelle voie où beaucoup d’entre nous sont devenus de simples observateurs, la consommation étant notre principale forme de participation. C’est l’une des raisons pour lesquelles le leg bien réel et brutal du colonialisme et du capitalisme — le changement climatique — reste bien présent sans être remis en question.

    Nous vivons sous les nuages de l’histoire, blottis le long des lignes de base de ses cartes.

    Pour faire face à ces héritages d’inégalités, nous, les peuples, devrions être placés au centre de la carte. Maintenant que le monde et sa grandeur géographique sont largement connus, il est essentiel de passer à une cartographie plus radicale, qui représente les enjeux du quotidien — la pollution, les discriminations de genre, la perte des habitats naturels. Une grande partie de ce qui a été infligé à notre monde au nom du progrès industriel et des normes sociales demeure dans les hautes sphères intellectuelles, toujours contrôlée par les pouvoirs traditionnels.

    En cartographiant ces réalités avec clarté, couleur et franchise, nous pouvons en discuter, en comprendre les effets et imaginer des solutions plus efficaces.

    La beauté cachée des cartes

    ►https://www.visionscarto.net/la-beaute-cachee-des-cartes

    L’ami Jean-Luc Arnaud nous a confié quelques extraits de son dernier livre, La beauté cachée des cartes, que nous présentons sur visionscarto.

    « Une belle carte, c’est presque un pléonasme tant elles sont le plus souvent considérées comme des documents à haute valeur esthétique. Ce livre associe des textes et des extraits de documents cartographiques pour le plaisir mais pas seulement. Sa préparation a été guidée par la recherche d’un lieu de rencontre entre imagination et connaissance. L’auteur le présente ici avec, en fin d’article, une galerie d’extraits de « belles cartes ».

    Kriegskarte der Schlacht bei Kunersdorf (Ausschnitt)

    Die ungewöhnlich reichhaltige Sammlung von Kriegskarten in der Kartenabteilung der Staatsbibliothek zu Berlin verteilt sich neben einem kleineren Bestand von ca. 2.500 Manöverkarten vorwiegend auf zwei große Sammlungen unterschiedlicher Provenienz.
    Die Königliche Bibliothek selbst sammelte kontinuierlich kartographische Darstellungen von militärischen Operationen - im Kern Feldzugs- und Schlachtenkarten (Signaturengruppe Kart. V). Sie enthält ca. 12.000 vorwiegend gedruckte Kartenblätter zur Militärgeschichte vom 16. Jahrhundert bis nach dem 1. Weltkrieg.
    Mit der Übernahme der Kartensammlung des aufgelösten Großen Preußischen Generalstabs im Jahr 1920 kamen dessen Bestände hinzu, wobei die Kriegskarten bis heute als separater Sammlungsteil erhalten blieben. In ihr befinden sich zahlreiche handgezeichnete Originale und Kopien, die wahrscheinlich für die Ausbildung im Kartenzeichnen, aber auch für die Schulung in Taktik, Strategie und Kriegsgeschichte angefertigt wurden. Diese Sammlung mit ca. 9.000 Blatt betrifft vorwiegend die Zeitspanne von 1700 bis 1900.
    Die ebenfalls in großer Zahl vorhandenen Karten von Kriegsschauplätzen, die nur die räumlichen Gegebenheiten, nicht aber die Ereignisse selbst darstellen, befinden sich überwiegend in den regional geordneten Sammlungsteilen.

    Derzeit sind nur die Karten der Bibliothekssammlung online recherchierbar. Für die Bestände des Generalstabs kann im Kartenlesesaal recherchiert werden. Beide Sammlungen sind nach dem Datum der Ereignisse geordnet.

    Diese Sammlung umfasst 23500 Objekte.

    (Teil-)Digitalisiert: Ja
    Thema: Kartographie, Neuere Geschichte (1789-1914), Militärgeschichte
    Sprache: Deutsch, Französisch
    Region: Deutschland, Frankreich, Polen, Russland, Übergreifend

    Erkenntnisgewinn: Warum geografisches Wissen im Zeitalter von Google Maps unverzichtbar bleibt
    ▻https://www.telepolis.de/features/Erkenntnisgewinn-Warum-geografisches-Wissen-im-Zeitalter-von-Google-Maps-u

    KI-generierte Illustration

    17.10.2025 von Christoph Jehle - Wer sich nur navigieren lässt, begreift die Welt nicht mehr und verliert das Gespür für Raum und Wirklichkeit. Kartenlesen bleibt eine Kulturtechnik der Erkenntnis.

    Geografie beschäftigt sich sowohl mit den natürlichen Grundlagen, als auch mit dem, was der Mensch daraus gemacht hat.

    Dabei kann man grundsätzlich Alles betrachten, was in der Fläche größer als ein Einzelgrab ist. Google Maps ist hingegen ein mehr oder weniger sinnvolles Navigationssystem, das weniger auf Erfahrung als auf online erreichbaren Daten aufbaut.

    Anders als das auf Mobilität hin optimierte Navigationssystem kann die Geografie einen kritischen Blick auf die dargestellten Realitäten bieten und ermöglicht die Kartierung von Themen, die in kommerziellen Diensten unterrepräsentiert sind, wie soziale Ungerechtigkeiten oder lokale Unsicherheiten.
    Der größere Reichtum

    Während Google Maps auf der globalen, oft anonymisierten Darstellung von Daten basiert, nutzt geografische Kartografie die Fähigkeit des Menschen, den Raum durch direkte Erfahrung, Wahrnehmung und kritische Analyse zu erschließen und so ein tieferes Verständnis für den lokalen Kontext zu entwickeln.

    Wo Google Maps die Erde nur zweidimensional mit dem Ziel abbildet, den Betrachter möglichst schnell von A nach B zu bringen, enthalten Karten deutlich mehr Informationen, die heute jedoch immer weniger Menschen lesen können, da sie ihre Informationen lieber aus Wikipedia und YouTube beziehen.

    Google entscheidet für den Betrachter anhand seiner Such-Historie, was ihm dargestellt wird und was nicht. Dabei ist den meisten Nutzern wohl gar nicht klar, was sie übersehen und was ihnen gar nicht angeboten wird.

    Somit können sich die von Google gewählten Darstellungen entsprechend den Nutzern unterscheiden und stellen keine Voraussetzung für eine Sachdiskussion zwischen zwei Nutzern dar.
    Karten zeigen für jeden Betrachter das Gleiche

    Die Darstellung in Karten werden vom Ersteller der Karten bestimmt und bieten für jeden Betrachter die gleichen Voraussetzungen dafür, was er auf der Karte sehen kann. Er muss es dann nur interpretieren.

    Bis vor wenigen Jahrzehnten konnte man Karteninterpretation noch studieren und anhand von Messtischblättern das Staatsexamen in Geographie erfolgreich meistern.

    Messtischblätter sind die allgemein bekannten Topographischen Karten im Maßstab 1:25.000, die auf Grundlage einer unmittelbaren Aufnahme im Gelände mittels Messtisch und Kippregel erstellt wurden. Messtischblätter im Maßstab 1:25.000 werden auch als 4-cm-Karten bezeichnet, weil vier Zentimeter auf der Karte einem Kilometer in der Realität entsprechen.

    Mittels Isohypsen – Linien, die Punkte mit gleicher Höhe verbinden und so als Höhenlinien auf topografischen Karten verwendet werden – wird auf topografischen Karten das Relief dargestellt, wobei der Abstand der Linien die Steilheit des Geländes anzeigt. Enge Linien bedeuten steiles Gelände, weite Linien flaches Gelände.
    In Google Maps fehlen die Perspektiven und die geschichtlichen Zusammenhänge

    Google Maps stellt als Instrument der aktuellen Navigation ein gutes Navigationsinstrument dar, was den Kompass weitgehend ersetzt hat. Es besitzt jedoch oft eine hegemoniale, konsumorientierte Sicht auf die Welt und blendet dabei soziale, wirtschaftliche und kulturelle Nischen und Fragestellungen aus, die dann aufwendig aus anderen Quellen beschafft werden müssen.

    Google basiert stark auf durch Nutzer und andere Quellen generierten Daten, die zwar für die Navigation nützlich sind, aber soziale Realitäten wie Diskriminierung, Gentrifizierung oder Überwachung nicht abbilden. Da sich Google meist an der Suchhistorie des Nutzers orientiert, besteht das Risiko einer Blasenbildung.
    Auch Karten zeigen nur einen Ausschnitt der Realität

    Anhand von Karten und den darin dargestellten Höhenlinien lassen sich noch heute frühere Nutzungen darstellen, ohne dass dafür ein Begleittext benötigt würde. Ehemalige Bahntrassen und aufgelassene Fabriken, welche man noch anhand damit verbundener Schornsteine leicht identifizieren kann, erzählen viel mehr über die betrachtete Landschaft, als es Google je darstellen könnte.

    In ihrer Generalisierung geben Karten oft nur einen bestimmten Ausschnitt der Realität wieder. So werden christliche Kirchen üblicherweise mit einem Kreuz-Symbol markiert, Moscheen oder Gebäude anderer Glaubenseinrichtungen jedoch häufig nicht, was als kartografisches Schweigen bezeichnet wird.

    In der Auswahl der Symbole zeigt sich oftmals der kulturelle Hintergrund des Erstellers. Geographen können ein tieferes, kontextualisiertes Verständnis von Orten entwickeln, das über die bloße Navigation hinausgeht. Die Geographie kann in der Folge auch kritische Fragen stellen und verborgene Aspekte des Raumes beleuchten, die in einer standardisierten Karte nicht sichtbar sind.
    Historische Karten haben bis heute Bedeutung

    Welche Bedeutung auch historische Karten bis heute haben können, lässt sich beispielhaft am Beispiel von Amerika zeigen. Zu einem Zeitpunkt, als der Kontinent von den Europäern nur ansatzweise bekannt war, hat der Kartograf Martin Waldseemüller aus dem heute zu Schallstadt zählenden Ort Wolfenweiler während seiner Anstellung als Kartograph im Gymnasium Vosagense in St. Dié in Lothringen auf einer Karte den neuen Kontinent nach Amerigo Vespucci mit dem Namen „America“ bezeichnete.

    Wie auf dieser Karte die Westküste Amerikas weitgehend korrekt wiedergegeben werden konnte, obwohl kein Europäer soweit vorgestoßen war, ist bis heute unbekannt.

    Das letzte erhaltene Original der Waldseemüllerkarte wurde 2001 für zehn Millionen US-Dollar mit einer Sondergenehmigung der Bundesrepublik Deutschland und des Landes Baden-Württemberg in die USA verkauft.
