Les poussières du Sahara qui remontent en Europe sont-elles radioactives du fait des essais nucléaires des années 1960 ?

Mi-octobre 2025, l’Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail alertait sur la pollution de l’air qui accompagne le déplacement – parfois sur plusieurs centaines, voire des milliers de kilomètres – des poussières de sable venues du Sahara.

De fait, le mois de mars 2022 avait connu un épisode de ce type particulièrement prononcé : un nuage de poussières venues du Sahara avait alors traversé l’Europe et teinté le ciel d’un voile orangé. Ce qui avait rapidement nourri la crainte d’un autre type de pollution. Ces poussières, qui semblent provenir du sud de l’Algérie, pourraient-elles avoir transporté des particules radioactives produites par les essais nucléaires français des années 1960 ? Une étude a répondu à cette question.


Plusieurs fois par an, le plus souvent au printemps et à l’automne, les tempêtes de poussières sahariennes transportent de grandes quantités de poussières du Sahara vers l’Europe.

Ces tempêtes sont de plus en plus intenses et de plus en plus fréquentes, selon le réseau Copernicus, ce qui suggère une incidence du changement climatique sur les schémas de circulations atmosphériques. À la mi-mars 2022, l’ouest du continent européen a ainsi connu un épisode exceptionnel – et fortement médiatisé – tant par sa durée que par la quantité de poussières déposées.

Or, au début des années 1960, la France a conduit des essais nucléaires en Algérie et a notamment déclenché l’explosion de quatre bombes atomiques atmosphériques entre 1960 et 1961. Une crainte, soulevée en 2022 par une association, était que les épisodes récurrents de poussières sahariennes puissent transporter avec elles vers l’Europe des substances radioactives provenant de ces essais nucléaires passés.

Dans notre recherche publiée en 2025, nous avons voulu évaluer la pertinence de cette hypothèse. Nous nous sommes appuyés sur le caractère exceptionnel de l’épisode de mars 2022 : la densité très élevée des dépôts survenus lors de celui-ci a facilité l’identification de l’origine des poussières et leur caractérisation.

Une origine compatible avec le sud de l’Algérie

Les poussières sahariennes qui arrivent en Europe peuvent provenir de différentes parties du désert du Sahara. La première question à laquelle nous avons voulu répondre était donc de savoir si les poussières de l’épisode de mars 2022 provenaient – ou non – de la zone géographique où ont été menés les essais nucléaires atmosphériques des années 1960.

Des analyses granulométriques, géochimiques et minéralogiques, menées sur 110 échantillons de poussières de 2022 collectés en Europe de l’Espagne à l’Autriche, ont permis de situer l’origine de celles-ci au sein d’une zone englobant notamment le sud de l’Algérie, où ont été menés des essais nucléaires dans les années 1960. Leur contenu en minéraux argileux (illite, kaolinite et palygorskite notamment), l’analyse des isotopes du plomb et du cortège des terres rares retrouvé dans les matières transportées ont été déterminants. Ces indices correspondent bien au profil typique des poussières provenant d’une zone qui inclut le sud de l’Algérie.

Par ailleurs, l’examen des images satellites et des données des stations de mesure de la qualité de l’air, combinées avec l’analyse a posteriori des trajectoires des masses d’air, ont permis de confirmer l’origine des poussières dans le sud de l’Algérie. D’autres recherches de modélisation indépendantes menées sur le même épisode confirment aussi l’origine sud algérienne des poussières.

Cette image satellitaire du 15 mars 2022 montre la présence des poussières de sable sur le sud-ouest de l’Europe.

L’origine des poussières de l’épisode de mars 2022 semble donc coïncider avec la zone où la France a effectué des essais nucléaires il y a plus de soixante ans. De quoi nourrir l’inquiétude des populations, d’autant plus que les épisodes de poussières sahariennes peuvent être très impressionnants : ils plongent les paysages dans une atmosphère jaunâtre.

Mais ces craintes sont-elles fondées ? Pour le savoir, nous avons analysé la quantité de césium radioactif (137Cs) contenue dans ces poussières en mars 2022.

Des niveaux de radioactivités négligeables pour la santé humaine

Au final nous observons de très faibles niveaux de césium 137 dans ces poussières, avec une médiane de 14 becquerels par kilogramme (Bq/kg). À titre de comparaison, la limite fixée par l’Union européenne pour la plupart des denrées alimentaires est de 1 000 Bq/kg. Dans les produits alimentaires destinés aux bébés, cette limite est de 400 Bq/kg.

Les effets résultants d’une ingestion accidentelle de ces particules sont donc négligeables, mais qu’en est-il de leur inhalation ? Nous avons calculé la quantité de césium radioactif en suspension dans l’air pendant cet épisode afin d’évaluer le débit de dose radioactif inhalé par les populations exposées pendant l’épisode de mars 2022. Celui-ci est 100 millions de fois inférieur au niveau autorisé par l’Union européenne.

Ces calculs sont rassurants: ils montrent que la radioactivité mobilisée par cet épisode de poussières a présenté un risque négligeable pour la santé humaine. Mais ils ne permettent pas, à eux seuls, de confirmer ou d’infirmer le lien éventuel avec les essais nucléaires des années 60. Pour en avoir le cœur net, il fallait aller plus loin.

Ce que révèle la signature isotopique de l’épisode

Nous avons vu précédemment que la zone source des poussières de mars 2022 est compatible avec la région de Reggane, au sud de l’Algérie. C’est dans cette région que la France a réalisé ses premiers essais nucléaires atmosphériques de 1960 à 1961. La zone de source est également compatible avec une région où la France a mené des essais souterrains dans des tunnels, et où deux fuites majeures ont été observées après les essais.

Pour mieux comprendre l’origine de la radioactivité – même très faible – contenue dans les poussières de mars 2022, nous avons analysé, en plus du césium 137, la signature de ces poussières en isotopes de plutonium 239 et plutonium 240.

Or, cette signature ne correspond pas à celle qui est attendue pour les retombées radioactives associées aux explosions des bombes nucléaires françaises. Au contraire, cette signature correspond plutôt au signal dit des « retombées globales », lié aux essais nucléaires réalisés par l’Union soviétique et par les États-Unis pendant les années 1950 et 1960, et qui ont marqué les sols du monde entier.

Notre étude permet ainsi de réfuter l’hypothèse selon laquelle les poussières sahariennes, telles que celles de l’épisode intense de mars 2022, ramèneraient en Europe des substances radioactives provenant des essais nucléaires menés par la France dans le Sahara.

Une recherche fondée sur la participation citoyenne

Ce travail a été rendu possible grâce à la collaboration des citoyens qui ont collecté des échantillons de poussières en réponse à une demande de chercheurs relayée sur les réseaux sociaux.

Nous avons ainsi pu obtenir un total de 110 échantillons de poussières sahariennes, provenant principalement d’Espagne (80 échantillons), de France (14) et d’Autriche (12). Cet échantillonnage spontané, mené à travers des milliers de kilomètres et en l’espace de quelques jours, aurait été impossible sans cette participation citoyenne.

Cette étude a aussi été rendue possible suite à l’interaction entre plusieurs laboratoires de recherche publics et grâce à l’utilisation de données produites et rendues accessibles par plusieurs agences climatiques et environnementales, comme le réseau Copernicus. À l’heure où certains pays, comme les États-Unis, désinvestissent de telles agences et compliquent l’accès aux données climatiques, cela rappelle l’importance des structures scientifiques publiques pour répondre aux préoccupations de la société.

Raila Odinga mastered the art of political compromise for the good of Kenya

Source: The Conversation – Africa (2) – By Westen K Shilaho, International Relations Scholar, University of the Witwatersrand

One of the markers of Kenyan statesman Raila Odinga was not just his courage in challenging the establishment but his ability to fortify it when circumstances demanded. An example was his willingness in 2007 to set aside his ambition at having been robbed of the presidency in a rigged election by agreeing to a coalition government with his opponent, President Mwai Kibaki.

Odinga espoused compromise and never squandered the political moment. Thus he ceded political ground for the greater national good and stability. This is how he helped to quell violence following disputed presidential elections in 2007. To his admirers this showed political maturity and astuteness.

This was not always interpreted as courageous, however. Some detractors labelled it as political weakness and betrayal. Despite numerous compromises, his detractors hardly ceded ground.

Just before his death, some of his detractors had labelled him the ultimate betrayer for solidifying his relationship with President William Ruto. Odinga worked with Ruto under what they termed broad-based government, formed at the height of mass protests to oust Ruto. Odinga propped up the embattled government under pressure over a controversial taxation bill and other problems. The nomination and sebsequent appointment of party members to the beleaguered government immediately deflated the protests. This demonstrated Odinga’s unmatched influence in Kenya’s politics.

I am a scholar of politics who has studied Kenya’s transition from authoritarianism to more democratic forms of politics. My 2018 book Political Power and Tribalism in Kenya examined the salience of ethnicity in the country’s multiparty politics.

It’s my view that Odinga employed compromise to integrate Kenya and hopefully live to fight another day. He had either official or informal working arrangements with all of Kenya’s five presidents bar one. He was therefore party to top decision making in the country without the benefit of executive power.

Had he thrown his weight behind the protest movement in 2024, it is highly likely that Kenya would have dissolved into chaos, as witnessed after disputed elections in 2007. He held that the mass protests in 2025 could have resulted in state collapse and bloodletting had he not intervened.

Through chutzpah and guile, Odinga escaped all attempts by his detractors to reduce him to an ethnic leader. Instead, he built alliances and connected with the working-class and rural poor, especially young Kenyans, who identified with his courage in Kenya’s human rights and democracy struggle.

Odinga: The bogeyman of Kenya’s establishment

A former Kenyan vice president, Michael Wamalwa Kijana, once described Odinga’s relationship with Kenyans as either Railamania or Railaphobia – people either passionately liked or irrationally feared him.

He commanded fanatical support among his co-ethnics and across Kenya, especially in his strongholds. But a section of Kenyan society opposed him, especially the clique that has controlled executive power and economic privileges since 1963.

Although Odinga was part of the establishment and rose to the position of prime minister (2008-2013), the only second Kenyan to occupy the post, he was treated with suspicion and disdain especially over the male circumcision rite that his community did not traditionally practise. His father, the founding vice president of Kenya who became the doyen of opposition politics, Jaramogi Oginga Odinga, suffered the same fate.

Raila Odinga’s detractors, among the elite and populace, mocked him while he was sick and irreverently celebrated his death.

This grouping, opposed to a capable welfare state based on inclusivity and egalitarianism, showed almost irrational antipathy towards Odinga. The establishment consistently schemed against him. His mass appeal, socialist orientation and populist politics posed a threat to the most reactionary cohort of the Kenyan political elite. Odinga’s uncompromising stance against the one-party dictatorship which earned him nine years of detention without trial, and implicated him in an abortive coup in 1982, did not endear him to all.

Odinga’s capacity to reinvent himself politically was astounding. Despite losing presidential elections five times, on several occasions because of state instigated fraud, he was undiminished. He was widely known in diplomatic circuits across Africa and globally. Memorably he mediated the Ivorian conflict following violently disputed elections in 2010. Thus, Odinga was among the pantheon of Kenya’s greats, a pan-Africanist and an internationalist.

Kenya’s moment of introspection

His death affords Kenyans an opportunity to reflect on the state of the Kenyan nation. He personified Kenya’s contradictions. Odinga’s long political career exhibited hope and despair for his supporters. In a country hamstrung by the ideology of ethnicised politics, there could not have been a more opportune moment for introspection.

Some of Odinga’s political moves turned out to be miscalculations. For instance, the grand coalition government formed in the wake of the 2007-2008 post-election maelstrom stabilised Kenya but did not address long term historical injustices.

Although it was the most inclusive since independence, it was bloated and mired in corruption, and perpetrated human rights violations. This rapprochement sealed his fate because it gave his opponents room to regroup. They regained the political initiative and eventually locked him out of the presidency forever.

His relationship with Ruto appeared to be more trusting than earlier ones, but Odinga still seemed to be the outsider in Kenya’s political matrix. Odinga’s shortcomings humanised him. Giants can have feet of clay.

Odinga bows out as the people’s president; the president that Kenya never had.

« Pas dans ma cour » : Les deux faces du NIMBYisme québécois

Au Québec, les citoyens disposent d’un pouvoir municipal rare au Canada : celui de bloquer par référendum des projets d’urbanisme dans leur quartier. Ce mécanisme de démocratie directe, inscrit dans la Loi sur l’aménagement et l’urbanisme depuis les années 1970, est à double tranchant : il permet une implication citoyenne forte, mais peut aussi paralyser des initiatives nécessaires pour lutter contre la crise du logement.

Les référendums municipaux s’inscrivent dans une tradition de participation citoyenne ancrée dans la culture politique québécoise. On remarque néanmoins que la participation à ces scrutins est souvent faible, tandis que le pouvoir de blocage est puissant.

En tant que spécialiste des études canadiennes, je m’intéresse depuis ma thèse de science politique aux procédures de participation citoyenne, et tout particulièrement à la tension entre démocratie participative et démocratie directe.

Cet article fait partie de notre série Nos villes d’hier à demain. Le tissu urbain connaît de multiples mutations, avec chacune ses implications culturelles, économiques, sociales et – tout particulièrement en cette année électorale – politiques. Pour éclairer ces divers enjeux, La Conversation invite les chercheuses et chercheurs à aborder l’actualité de nos villes.

Tourisme et démocratie locale : la leçon de Petite-Rivière-Saint-François

En 2022, la municipalité de Petite-Rivière-Saint-François, dans Charlevoix, a organisé un référendum local visant l’assouplissement de deux règlements de zonage relatifs aux résidences de tourisme.

Le résultat a été sans appel, puisque plus de 70 % des électeurs ont voté contre l’assouplissement des règles qui aurait permis d’accueillir davantage de chalets locatifs près du Massif. Le message des citoyens était clair : préserver la qualité de vie et le caractère du territoire face à une pression touristique jugée excessive.

Le scrutin a eu un effet immédiat avec le rejet des règlements, stoppant ainsi un projet de développement.

À Québec, un vote favorable à la ville compacte

Deux ans plus tard, à Québec, dans l’arrondissement de Charlesbourg, le projet Maria-Goretti a connu une issue inverse.

Près de la moitié des électeurs de la zone concernée se sont déplacés pour voter, et cette fois, la majorité a approuvé le projet résidentiel soumis à approbation référendaire.

L’administration municipale a salué le résultat comme un signe d’adhésion à une densification maîtrisée, alors que les opposants y voyaient un précédent inquiétant pour le patrimoine local.

Au Québec, l’urbanisme passe aussi par les urnes

Ces deux exemples illustrent la vitalité – mais aussi les tensions – de la démocratie urbaine au Québec.

Contrairement à la plupart des provinces canadiennes, où les projets d’urbanisme sont décidés par les conseils municipaux sans recours direct aux électeurs, le Québec conserve des mécanismes d’approbation référendaire hérités de la Loi sur l’aménagement et l’urbanisme (LAU).

Les citoyens qui s’estiment lésés par un projet peuvent demander l’ouverture d’un registre, recueillir des signatures, et si le seuil requis est atteint, déclencher un vote.

Participation ou paralysie ? Le dilemme des référendums d’urbanisme au Québec

Ce dispositif, qui remonte aux années 1970, repose sur une idée forte : permettre à ceux qui habitent un quartier de participer à la décision sur son avenir. Mais il est aujourd’hui au cœur d’un débat : favorise-t-il réellement la démocratie, ou crée-t-il des zones de veto locales capables de bloquer toute initiative de densification ?

Le paradoxe tient à la fois dans la mobilisation et dans la portée.

Lorsqu’un vote a lieu, la participation dépasse rarement 50 %. Pourtant, un petit nombre d’électeurs peut décider du sort d’un projet d’intérêt collectif. En 2017, le gouvernement du Québec a tenté de moderniser ces procédures avec le projet de loi 122, qui visait à donner plus d’autonomie aux municipalités et à encourager d’autres formes de participation.

Plusieurs villes ont alors remplacé les référendums par des consultations publiques plus ouvertes, misant sur la pédagogie et le dialogue.

L’Office de consultation publique de Montréal

C’est le cas de Montréal, où l’Office de consultation publique (OCPM) organise régulièrement des audiences sur les grands projets urbains.

La consultation plutôt que le référendum

À Boisbriand, la municipalité a choisi de multiplier les consultations plutôt que de déclencher des votes formels, afin d’éviter que quelques dizaines de signatures ne suffisent à bloquer un règlement.

Mais le référendum local conserve une charge symbolique forte.

Dans un contexte de méfiance croissante envers les promoteurs immobiliers, il apparaît comme le dernier rempart pour protéger les citoyens contre des décisions jugées opaques.

Le NIMBYisme à la québécoise : entre défense du cadre de vie et justice sociale

Cette défiance s’exprime aussi face aux élus municipaux, souvent perçus comme trop proches des intérêts privés. Le « non » devient alors une manière de reprendre le contrôle du territoire, de ralentir un rythme de transformation jugé trop rapide.

Ce réflexe de défense du cadre de vie est parfois associé au NIMBYisme, acronyme de « Not In My Backyard ».

L’expression désigne ceux qui soutiennent les politiques publiques en général, mais refusent leur application à proximité de chez eux. On parle souvent de NIMBYs « de droite », attachés à la valeur foncière de leur propriété et hostiles à la densification.

Mais le Québec voit émerger une autre forme de contestation, un NIMBYisme « de gauche », ancré dans la critique de la spéculation immobilière et de l’embourgeoisement. Les opposants ne défendent plus seulement leur jardin, mais aussi le droit au logement, la mixité sociale et la préservation du patrimoine collectif.

Référendums, NIMBYisme et crise du logement : un équilibre impossible ?

Ces deux visages du NIMBYisme se croisent et s’affrontent souvent dans les débats municipaux.

Un même projet peut être rejeté pour des raisons très différentes : les uns craignent la hausse du trafic ou la perte d’intimité, les autres redoutent l’arrivée de condominiums de luxe chassant les locataires modestes. La frontière entre conservatisme local et résistance progressiste devient floue, et le référendum en est le miroir.

Dans un contexte de crise du logement, cette ambivalence devient un enjeu politique majeur. Les gouvernements municipaux et provinciaux doivent arbitrer entre la participation et l’efficacité. Trop de recours citoyens peuvent ralentir des projets nécessaires, tandis que trop peu de recours risquent de creuser le fossé entre élus et habitants.

Les maires, eux, se retrouvent pris entre deux feux : on leur reproche à la fois de céder aux promoteurs et de ne pas aller assez vite pour répondre à la demande.

Sortir de l’impasse

Plusieurs villes expérimentent des dispositifs de co-construction : jurys citoyens, laboratoires urbains, consultations hybrides.

Ces formes de participation ne remplacent pas le vote, mais cherchent à l’enrichir. Elles permettent d’impliquer les habitants dès la conception d’un projet, avant que les positions ne se figent dans un « oui » ou un « non ». L’enjeu n’est pas de supprimer la démocratie directe, mais de la rendre plus délibérative, moins défensive.

Les référendums municipaux québécois rappellent que la démocratie locale n’est jamais acquise. Ils traduisent à la fois une volonté d’autonomie citoyenne et une peur de perdre le contrôle face à des transformations urbaines rapides. Dans une époque où les villes se densifient, où le logement devient un bien rare, cette tension est inévitable.

Plutôt que de l’opposer, il s’agit d’en faire le moteur d’un nouveau pacte urbain où la parole des habitants pèse sans pour autant paralyser l’action collective.

Quand la Constitution québécoise ignore les peuples autochtones

Source: The Conversation – in French – By Karine Millaire, Professeure adjointe en droit constitutionnel et autochtone, Université de Montréal

La Coalition avenir Québec (CAQ) projette non seulement d’imposer une Constitution du Québec aux Premières Nations et Inuit, mais en plus le projet de loi s’inscrit en contradiction avec les droits des Autochtones garantis par la Constitution canadienne. Adopter une telle approche en 2025 ignore des droits constitutionnels bien reconnus, reproduit la vieille approche coloniale et constitue une grave erreur juridique comme historique.

Il y a plus de 40 ans, on enchâssait dans la Constitution canadienne l’article 35 de la Loi constitutionnelle de 1982. Cette disposition garantit les droits des peuples autochtones issus de traités et leurs droits ancestraux. Le projet de Constitution de la CAQ en fait complètement fi. Aucune disposition du projet de loi déposé ne traite des droits constitutionnels autochtones. Plus encore, les quelques mentions des Premières Nations et Inuit au préambule du projet de loi 1, Loi constitutionnelle de 2025 sur le Québec, sont de nature à minimiser des droits pourtant clairement reconnus.

On y mentionne en effet les Autochtones pour affirmer qu’ils « existe[nt] au sein du Québec ». On ne reconnaît pas qu’il s’agit de « peuples », contrairement à la Déclaration des Nations unies sur les droits des peuples autochtones de 2007, mais plutôt de simples « descendants des premiers habitants du pays ». On désigne même nos nations sous des appellations coloniales francisées, rappelant le processus d’effacement des noms de nos ancêtres.

Le projet de loi affirme l’« intégrité territoriale » ainsi que la « souveraineté » culturelle et parlementaire du Québec. Les Autochtones ne pourraient selon ce projet de Constitution que « maintenir et développer leur langue et leur culture d’origine ». Autrement dit, les droits territoriaux et de gouvernance garantis en vertu de l’article 35 de la Loi constitutionnelle de 1982 sont complètement ignorés, voire niés.

L’imposition coloniale des « droits collectifs » de la « nation québécoise » sur les droits collectifs et fondamentaux des peuples autochtones est également affirmée par des dispositions d’interprétation spécifiques. Alors que les droits des Premières Nations et Inuits sont réduits, on précise que ceux de la nation québécoise « s’interprètent de manière extensive ».

De plus, on propose la création d’un Conseil constitutionnel ayant pour mandat d’interpréter la Constitution du Québec. Or, les facteurs explicitement précisés dont devrait tenir compte ce Conseil ne portent que sur les droits et « caractéristiques fondamentales du Québec », son « patrimoine commun », son « intégrité territoriale », ses « revendications historiques », son « autonomie » et son « économie ». Pas une seule mention ici de l’existence des peuples autochtones ou de leurs droits.

Les Wendat, Kanien’keháka (Mohawk), Attikamekw, Anishinaabe, Cris (Eeyou Istchee), Abénakis, Mi’kmaq, Innus, Naskapis, Wolastoqiyik et Inuit n’existent pas sur un territoire « appartenant » au Québec. C’est le Québec qui existe sur les territoires dont ces nations sont les gardiennes et pour lesquels nous avons une responsabilité commune. Nos droits ne sauraient être effacés à nouveau en 2025 par ce projet de Constitution du Québec.

La Cour suprême et les tribunaux du Québec comme d’ailleurs au pays reconnaissent de façon constante que les peuples autochtones ont une souveraineté préexistante à celle imposée historiquement par la Couronne, c’est-à-dire une souveraineté qui existait bien avant les débats sur l’autonomie du Québec au Canada. Cette souveraineté existe toujours et doit être réconciliée avec celle de l’État dans un esprit de « justice réconciliatrice ».

Il en découle des droits concrets en matière de consultation, de consentement, d’autonomie gouvernementale. Aucune dérogation à ces droits n’est possible, contrairement aux droits et libertés visés par la clause dérogatoire de l’article 33 de la Charte canadienne des droits et libertés.

Or, la CAQ souhaite mettre à l’abri de contestations constitutionnelles toute disposition législative qui « protège la nation québécoise ainsi que l’autonomie constitutionnelle et les caractéristiques fondamentales du Québec » en interdisant toute contestation judiciaire d’un organisme qui utiliserait pour ce faire des fonds publics du Québec. Fort nombreuses sont les organisations qui reçoivent des fonds publics, incluant celles ayant justement la mission publique de protéger la société contre les actions illégales ou délétères de l’État. Il s’agit d’un des fondements de l’État de droit.

Du point de vue autochtone, cette interdiction rappelle l’époque coloniale où il était interdit aux Premières Nations de contester les actions illégales de l’État qui avaient pour but de les déposséder de leurs terres, de nier leurs droits et de les assimiler. Cette mesure a participé au génocide des peuples autochtones au Canada.

Le projet de loi sur le régime forestier est un important recul pour les droits des Autochtones


Un projet de loi qui s’ajoute à d’autres violations de droits par Québec

Ce projet de Constitution du Québec s’ajoute à plusieurs autres atteintes claires aux droits autochtones. Pensons à la contestation de Québec de la loi fédérale reconnaissant le droit inhérent des peuples autochtones de mettre en place leurs propres politiques familiales et de protection de la jeunesse. La Cour suprême lui a donné tort et a confirmé la constitutionnalité de la loi fédérale.

La CAQ a aussi refusé d’exclure les étudiants autochtones des règles de renforcement de la Charte de la langue française (projet de loi 96), alors que les langues autochtones ne menacent pas le français. Cette décision accroît les obstacles aux études supérieures et limite les droits de gouvernance en éducation des peuples autochtones. La contestation de la constitutionnalité de la loi québécoise est en cours.

Enfin, pensons au récent projet de loi 97 visant à réformer le régime forestier, lequel avait été sévèrement critiqué. Celui-ci proposait un retour en arrière et rappelait l’approche préconisée au début de la colonisation du territoire, alors que l’industrie jouait un rôle accru en matière de gouvernance du territoire. Le projet de loi a finalement été abandonné fin septembre, mais il aura fallu que les peuples autochtones se battent à nouveau pour faire respecter leurs droits.

Moderniser la Constitution du Québec pour respecter les droits des Autochtones

Le contexte n’est plus le même qu’à la fondation du pays en 1867 ou lors des discussions des années 1980 ayant précédé le rapatriement de la Constitution. En 2025, il ne serait ni légal, ni légitime, d’adopter une Constitution du Québec ignorant les droits des Autochtones.

Une Constitution québécoise doit minimalement reconnaître les mêmes droits ancestraux et issus de traités que ceux protégés par la Constitution canadienne et les décisions des tribunaux en la matière. Cela inclut des droits de gouvernance notamment quant au territoire.

De plus, la Charte des droits et libertés de la personne est silencieuse sur les droits autochtones. L’article 10 garantissant le droit à l’égalité devrait être modifié pour indiquer que l’identité et le statut autochtone sont des motifs de discrimination spécifiquement prohibés au Québec. Cette Charte devrait également reconnaître expressément le droit à la sécurité culturelle afin que toute personne autochtone ait accès aux services publics de façon équitable. Ces changements permettraient qu’un mandat conséquent soit donné à la Commission des droits de la personne pour agir afin d’enrayer cette discrimination.

Le Québec doit également mettre en œuvre la Déclaration des Nations unies sur les droits des peuples autochtones. Le Canada fait partie de nombreux pays qui se sont engagés à le faire et nos tribunaux ont commencé à s’y référer. La Déclaration exige de construire avec les peuples autochtones les politiques qui touchent à leurs droits, de respecter leur consentement et leur autonomie ainsi que le droit d’avoir accès aux services publics sans discrimination, à l’instar du Principe de Joyce.

Le projet de Constitution de la CAQ ne correspond en rien à ce qu’un véritable processus constituant doit faire. Ni les Québécois ni les peuples autochtones ne participent à cette démarche. Une Constitution devrait être pensée pour au moins les sept prochaines générations, comme nous l’enseignent les Aînés, et non en vue de la prochaine élection.

La conversación docente: no pregunte a la IA lo que puede hacer por usted

La frase de nuestro título: “No pregunte a la IA qué puede hacer por usted…”, además de parafrasear a Kennedy, apunta a una cuestión básica respecto al papel de la inteligencia artificial en la educación: entender en qué nos ayuda y en qué nos perjudica su uso. Hoy traigo perspectivas nuevas y propuestas concretas, como siempre, para usar en la clase, tanto de secundaria como de universidad.

La IA llegó al panorama educativo con la promesa de personalizar el aprendizaje, facilitando de esta manera el rendimiento de los estudiantes más rezagados. Pero una reciente investigación de María Luisa Fanjul Fernández, Francisco José Pradana Pérez y Joaquín Pérez Martín de la Universidad Europea ha comprobado que esta tecnología no reduce la brecha entre estudiantes “buenos” o “malos”. Los que ya tienen buenos hábitos de estudio son los que consiguen profundizar en los contenidos, mejorar su comprensión y desarrollar nuevas competencias gracias a la IA. El resto piensa sobre todo en ahorrar tiempo: algunos para mejorar productividad (aunque no las notas) y otros simplemente por esforzarse menos.

“De esta manera, lejos de igualar oportunidades, esta herramienta puede ampliar la brecha educativa. Por ejemplo, hemos visto que entre los estudiantes con mejor rendimiento, el 72 % asegura revisar o contrastar siempre la información generada por la IA. Entre los de peor rendimiento, solo el 28 % lo hace”, advierten los autores.

La mente humana adora los atajos. Está en nuestro ADN. Que los universitarios no prioricen aprender más y mejor es un problema de actitud y objetivos. Aquellos que se apoyen demasiado en la inteligencia artificial, aunque saquen el grado, no saldrán igual de preparados. ¿Qué pasa en secundaria? Las mentes de los adolescentes están en pleno crecimiento, y hay tareas escolares que precisamente contribuyen a ese desarrollo cognitivo. ¿Qué hacemos para convencerles de que no les compensa, y para demostrarles cómo sí pueden hacerlo bien?Por ejemplo: leer un libro y resumirlo. En su artículo, Esther Nieto Moreno de Diezmas de la Universidad de Castilla-La Mancha, explica lo que aporta esta tarea escolar al cerebro desde el punto de vista cognitivo, pero también emocional y metacognitivo. Ahorrar tiempo está muy bien cuando tenemos encima una fecha de entrega, pero, advierte esta experta, “conviene pararse a analizar en qué estamos ahorrando exactamente y cuáles son las contrapartidas”.

Coinciden con ella Jorge Chauca García, de la Universidad de Málaga, que ofrece ejemplos concretos de qué sí se puede hacer con la inteligencia artificial en la asignatura de Historia en secundaria y Bachillerato; y Luis Daniel Lozano Flores, de la Universidad de Guadalajara México, que insiste en esta idea: la tecnología potencia nuestras capacidades, pero para que no acabe sustituyéndolas, tenemos que ser estratégicos. Resumiento: no es lo que puede hacer por nosotros la IA, es lo que nosotros podemos hacer con ella.

Otros temas de interés de esta quincena tienen que ver con la diferencia entre enseñar y adoctrinar, estudiar un grado o máster en otro idioma, y cómo fomentar la autoconfianza de las niñas en matemáticas para reducir la brecha de género en esta disciplina. Espero que los disfruten. Para quienes viven en Madrid (o también para los que no, porque estará disponible en streaming), no quiero dejar pasar la oportunidad de animarles a acudir a nuestro encuentro en el Espacio Telefónica con el experto en neuroeducación David Bueno. Hablaremos del bienestar digital de los niños y los adolescentes, del papel que puede o debería tener la tecnología en el aprendizaje, y de cómo puede mejorar la enseñanza aplicando lo que sabemos del desarrollo cognitivo infantil y adolescente.

Woven baskets aren’t just aesthetically pleasing – materials science research finds they’re sturdier and more resilient than stiff containers

People have been using flat, ribbonlike materials, such as reed strips, to make woven baskets for thousands of years. This weaving method has reemerged as a technique for engineers to create textile and fabric structures with complex geometry. While beautiful and intricate, these baskets can also be surprisingly strong.

We are a team of structures and materials scientists at the University of Michigan. We wanted to figure out how basketlike structures that use traditional weaving techniques can be so sturdy, load-bearing and resilient.

To explore the resilience of baskets, we designed a series of small woven units that can be assembled into larger structures. These woven designs provide almost the same stiffness as nonwoven structures, such as plastic bins. They also do not fracture and fail when bent and twisted the way nonwoven, continuous systems (made out of a continuous sheet material) do.

Our basketlike woven structures have many potential applications, including tiny robots that are very damage resilient – these robots can be run over by a car and still do not fail. We could also make woven clothes to help protect people from severe impacts such as car crashes. We made these woven structures using Mylar (a type of polymer material), wood and steel.

Testing woven baskets

Early humans made baskets by weaving slender strips of bark or reeds, and some Indigenous societies use these techniques today. Basket weaving was an efficient way to turn one-dimensional strips into three-dimensional containers.

This geometric benefit is a direct motivation for basket weaving, but in our study published in August 2025 in Physical Review Research, we wanted to find out whether basket weaving can provide more than aesthetic value in modern science and engineering.

In our experiment, we compared woven and nonwoven containers that had the same overall shape and were fabricated using the same amount and type of materials.

The “ribbons” we used were 10 millimeters wide and two-tenths of a millimeter thick. They were always woven in the same over/under/over/under pattern. We wove baskets from the flat ribbons and then created models using 3D scans of these woven containers that helped us examine the underlying similarities and differences between the woven and continuous structures.

We found that these containers had similar stiffness to containers not made from woven materials, and they also went back to their initial shape after we bent or twisted them.

A figure with three panels, the first shows two nearly identical boxes, one woven and one continuous (non-woven). The second panel shows both boxes being twisted and squished. The third shows both structure afterwards. The woven has retained its shape while the continuous looks squished and twisted.
When comparing rectangular boxes made of woven sheets of Mylar polyester ribbons and a continuous sheet of the same material, the woven structure could still bear a load after undergoing compression (axial buckling) and twisting (torsional buckling), while the continuous sheet could not. These structures are made of Mylar (a type of polymer material).
Tu & Filipov, 2025

When you place a heavy object on a woven structure, the ribbons are mainly being stretched instead of bent. This stretching makes them stiff because ribbons are much stiffer when they are stretched compared to bent. On top of that, the ribbons are not rigidly connected in woven structures, which gives them their extraordinary resilience.

By harnessing basket-weaving techniques, engineers can potentially create better materials for cars, consumer devices such as smartwatches, and soft robots, which are robots made from soft materials instead of rigid ones. Essentially, these techniques could improve any device when the material needs to be stiff and resilient.

What’s next

Our research team is still exploring a few big, unanswered questions about these woven baskets.

First, we want to understand how the geometry of the woven baskets determines their stiffness and resilience, and create an analytical or numerical model to describe this relationship. We’d then like to use that model to design woven structures that fit a target stiffness and resilience. Most woven baskets are handmade because their geometry is complex and difficult for a machine to manufacture.

Second, we’d like to figure out how to create a machine that can fabricate woven baskets autonomously. Automated machines can produce two-dimensional woven fabrics, but we’d like to learn how to modernize and digitalize the ancient craft of three-dimensional basket weaving.

Third, we want to understand how to integrate electronic materials into three-dimensional basket weaving to create next-generation robotic textiles. These robotic textiles could sense, actuate, move around, bear a load, stay resilient to accidental overload and safely interact with humans at the same time.

Basket-weaving research and applications

Ours isn’t the only study exploring the complex geometry of basket weaving and the potential of applying basket-weaving techniques to architectural design.

For example, researchers teamed up with an artist to tweak a popular basket-weaving approach, finding ways to weave the ribbons and produce any curvature they desired. Later, the same research team used this methodology to fabricate woven domes. They found that they could tune the stiffness and stability of woven domes by varying the curvature of the ribbons.

In another relevant study, researchers built algorithms that optimized the size, shape and curvature of ribbons, then used those ribbons to weave together a geometrically sophisticated structure.

Our new work and these other teams’ work is putting a modern spin on technology that has likely been around since the dawn of humanity.

The Trump administration’s anti-immigrant housing policy reflects a long history of xenophobia in public housing

Source: The Conversation – USA – By Rahim Kurwa, Associate professor of Sociology, University of Illinois Chicago

The U.S. housing market has been ensnared in a growing affordability crisis for decades.

The problem has gotten dramatically worse in recent years. Since 2019, home prices are up 60% nationwide. A record-high 22 million renters are “cost-burdened” – spending more than 30% of their income on housing.

Meanwhile, stagnant wages, limited housing supply and lagging federal assistance have helped leave more than 770,000 Americans homeless.

Despite these varied reasons, Vice President JD Vance has blamed the housing affordability crisis on undocumented immigrants. In August 2025, he attributed rising housing costs to immigration: “You cannot flood the United States of America with … people who have no legal right to be here, have them compete against young American families for homes, and not expect the price to skyrocket.”

Deportations, he argued, would lower housing prices. “Why has housing leveled off over the past six months? I really believe the main driver is … negative net migration.”

Despite Vance’s claims, research shows that immigration is not a substantial cause of unaffordable housing. In fact, studies have found that deportations exacerbate housing shortages through reductions in the construction workforce, which lead to lower production of housing units and higher prices.

From this perspective, its hard to see the administration’s deportation policy as a real effort to solve the housing crisis. Rather, it is using the housing crisis as a way to justify mass deportations to the public.

The current administration’s anti-immigrant housing policy reflects a long history of xenophobia in housing. As a sociologist of housing, I’ve traced the history of racial segregation in housing in Los Angeles County. I have found that the same far-right groups that sought to defeat public housing construction and maintain racially restrictive agreements in post-World War II Los Angeles also advocated to ban immigrants from U.S. housing programs.

Earlier anti-immigrant housing plans

Among the leaders of these efforts was the far-right politician and activist Gerald L.K. Smith. Described in 1976 by historian John Morton Blum as “the most infamous American fascist,” Smith helped bridge the American right’s 1940s conspiratorial and isolationist America First era and its 1960s anti-civil rights era.

Smith traveled the country advocating a Christian nationalist vision for American society, offering a religious justification for anti-communism and opposition to civil rights. He also ran for president unsuccessfully in 1944, 1948 and 1956.

After settling in Los Angeles in 1953, Smith led Red Scare campaigns – driven by hostility to communism – across the country.

In my research, I found that Smith was an early proponent of anti-immigrant housing policy. His 10 principles included a call to “Stop immigration in order that American jobs and American houses may be safeguarded for American citizens.” Elsewhere he called to “Release housing units occupied by aliens in order that they may be occupied by veterans and other American citizens.”

Smith wasn’t alone. His efforts were part of a broader environment in which public officials and local media worked to stop construction of public housing in Los Angeles in the 1950s, accusing its proponents of communism.

Recent anti-immigrant policy in housing

State and federal policymakers have also incorporated anti-immigrant stances into American housing policy over the past half-century.

The 1980 Housing and Community Development Act was the first federal legislation to specifically bar undocumented immigrants from public housing programs. Welfare reform in 1996 further restricted public housing assistance to only legal permanent residents and those with asylum or refugee status.

Echoing the alien land laws of the late 1800s that prohibited foreign property ownership, policymakers in the 2000s in states such as Pennsylvania and Texas passed laws forcing landlords to check immigration status as a condition of rental – though this was struck down by the courts.

Today, immigrant tenants experience fewer housing rights than citizens. These inequalities fall particularly hard on unauthorized immigrants who experience high rates of housing cost burden, crowding and poor housing conditions.

The Trump administration aims to expand restrictions on immigrants in public housing even further. The Department of Housing and Urban Development is in the process of adopting rules that will evict entire families if even one member is ineligible for assistance based on immigration status. Current law allows those families to live in public housing, while prorating their benefits to account for an ineligible member.

From Smith to Vance, anti-immigrant housing policies have been cast as a way for citizens to get more housing. But they fail to prevent or solve the housing shortage driving the crisis.

For example, the Trump administration’s effort to evict mixed status families from public housing will affect roughly 25,000 households. Setting aside the fact that those families may then be made homeless, that number is only one-tenth the amount of housing that the U.S. has lost due to the defunding and demolishing of public housing since 1990.

Indeed, many of the Trump administration’s immigration and economic policies are likely to exacerbate the housing crisis. The Trump administration has made deportation a priority and has significantly increased deportation rates compared to recent years, while instituting historically high tariffs on imports.

Deportations reduce the housing construction workforce, lowering the number of units built and increasing costs. And tariffs raise prices on building materials such as lumber, steel and aluminum. The National Association of Home Builders estimates that recent tariffs have raised building costs by US$10,900 per home.

In early 2025, the Department of Government Efficiency canceled or delayed a series of HUD grants for housing assistance programs. And the Trump administration has announced plans for more cuts to the nation’s already insufficient housing assistance budget.

Vance, like Smith before him, presents the issue like a pie, where citizens can get a larger slice only by deporting immigrants. But the reality is that the pie can be bigger: The government can fully fund the housing needs of all Americans for less than it has spent on its other priorities. The recently passed “big, beautiful bill,” for example, allocates more funding to border and interior enforcement per year than key rental assistance programs, public housing and Housing Choice Vouchers allocate for housing.

In Smith’s time, everyday Americans resisted this gambit, speaking out to protest his views. Today, as Smith’s anti-immigration housing ideas have ascended to the national stage, the housing justice community is speaking out against anti-immigrant housing policy and offering an alternative vision of how the U.S. can provide housing for all.

Despite naysayers and rising costs, data shows that college still pays off for students – and society overall

No industry has perhaps felt the negative effect of a radical shift in federal policy under the second Trump administration more than higher education.

Many American colleges and universities, especially public institutions, have experienced swift and extensive federal cuts to grants, research and other programs in 2025.

Meanwhile, new restrictive immigration policies have prevented many international students from enrolling in public and private universities. Universities and colleges are also facing other various other challenges – like the threat to academic freedom.

These shifts coincide with the broader, increasingly amplified argument that getting a college degree does not matter, after all. A September 2025 Gallup poll shows that while 35% of people rated college as “very important,” another 40% said it is “fairly important,” and 24% said it is “not too important.”

By comparison, 75% of surveyed people in 2010 said that college was “very important,” while 21% said it was “fairly important” and 4% said it is “not too important.”

Still, as a scholar of education, economic development and social issues, I know that there is ample and growing evidence that a college degree is still very much worth it. Graduating from college is directly connected to higher entry-level wages and long-term career success.

A growing gap

Some people argue that a college degree does not matter, since there might not be enough jobs for college graduates and other workers, given the growth of artificial intelligence, for example. Some clear evidence shows otherwise.

An estimated 18.4 million workers with a college degree in the U.S. will retire from now through 2032, according to Georgetown University’s Center on Education and the Workforce. This is far greater than the 13.8 million workers who will enter the workforce with college degrees during this same time frame.

Meanwhile, an additional 700,00 new jobs that require college degrees – spanning from environmental positions to advanced manufacturing – will be created from now through 2032.

The gap between those expected to leave and enter the workforce with college degrees creates a serious problem. One major question is whether there will be enough people to fill the available jobs that require a college degree.

In 2023, foreign-born people made up 16% of registered nurses in the U.S., though that percentage is higher in certain states, like California. But restrictions on immigration could limit the number of potential nurses able to fill open positions.

Nursing and teaching are two fields expected to grow over the next few decades, and they will require more workers due to retirements.

Other fields, like accounting, engineering, law and many others, are also expected to have more college-educated workers retire than there are new workers to fill their positions.

Worth the cost

The average annual salary of a college graduate from the class of 2023 was US$64,291 in 2024, according to the National Association of Colleges and Employers.

The overall average salary for this graduation class one year after they left school marked an increase from the average $60,028 that the class of 2022 earned in 2023, equivalent to $63,850 today.

While there is not available data that offers a direct comparison, full-time, year-round workers ages 25 to 34 with a high school diploma earned $41,800 in median annual earnings in 2022, or $46,100 today.

Overall lifetime earnings for those with college degrees is about about $1.2 million more than people with a high school make, according to the recent Georgetown findings.

People who earn more generally have more money to support their families and contribute to their immediate communities. Their higher taxes also contribute to the U.S. economy, supporting needed services like education, public safety and health care.

People with college degrees are also more likely than those who are not college graduates to vote, volunteer and make charitable donations to help others in need.

College matters for individuals, but it clearly also helps improve the economy.

With 64 public colleges across the state, the State University of New York system is the largest post-secondary network of higher education schools in the country. For every $1 the state of New York invests in SUNY, the SUNY system returns $8.70 to the state in terms of economic growth, according to 2024 findings by the Rockefeller Institute, an independent public policy research organization affiliated with SUNY. And that is only one state.

A new way forward

It isn’t likely that the expected number of college-educated people who will soon retire will suddenly decrease, or that the anticipated number of people entering the workforce will unexpectedly increase.

There are practical reasons why some people do not want to go to college, or cannot attend. Indeed, the percentage of young people enrolled as college undergraduates fell almost 15% from 2010 through 2022.

For one, tuition and fees at private colleges have increased about 32% since 2006, after adjusting for inflation. And in-state tuition and fees at public universities have also grown about 29% since 2006.

The total of federal student loan debt for college has also tripled since 2007. It stood at about $1.84 trillion in 2024.

I believe that in order to ensure enough college-educated people can fill the anticipated work openings in the future, universities and the government should embrace needed changes to increase both enrollment and completion rates.

Artificial intelligence will transform work worldwide, for example, and that shift should be incorporated into higher education curriculum and degrees. Soft skills – like problem-solving, collaboration, presentation and writing skills – will become more important and should be prioritized in the learning process.

I believe that universities should also prioritize experiential education, including paid internships that offer students academic credit. This can help students gain experience that is both accredited and is connected to direct career pathways.

Universities and high schools could also expand how much they offer microcredentials – or short, focused learning programs that offer practical skills in a specific area – so students can connect their education with clear career pathways.

These reforms aren’t easy. They require a commitment to change, and all of this work will require deep partnerships with the government. While that might be a heavy lift currently at the federal level, it is both possible and achievable to make advances on these and other changes at the state level.

American universities and colleges have always been key to preparing the workforce for economic opportunity. At the end of World War II, for example, Columbia University and IBM worked together to help create the academic discipline now called computer science.

This action did more than help one university or one employer. It fueled change across higher education and across private companies and the government, leading to massive economic growth.

Universities have made countless other contributions to strengthen and expand the economy. Considering solutions to some of the challenges that stop students from going to college could help ensure that more students see the value in a college education – and a tangible way for them to connect it to a future career.

AI is changing who gets hired – what skills will keep you employed?

Source: The Conversation – USA (2) – By Murugan Anandarajan, Professor of Decision Sciences and Management Information Systems, Drexel University

The consulting firm Accenture recently laid off 11,000 employees while expanding its efforts to train workers to use artificial intelligence. It’s a sharp reminder that the same technology driving efficiency is also redefining what it takes to keep a job.

And Accenture isn’t alone. IBM has already replaced hundreds of roles with AI systems, while creating new jobs in sales and marketing. Amazon cut staff even as it expands teams that build and manage AI tools. Across industries, from banks to hospitals and creative companies, workers and managers alike are trying to understand which roles will disappear, which will evolve and which new ones will emerge.

I research and teach at Drexel University’s LeBow College of Business, studying how technology changes work and decision-making. My students often ask how they can stay employable in the age of AI. Executives ask me how to build trust in technology that seems to move faster than people can adapt to it. In the end, both groups are really asking the same thing: Which skills matter most in an economy where machines can learn?

To answer this, I analyzed data from two surveys my colleagues and I conducted over this summer. For the first, the Data Integrity & AI Readiness Survey, we asked 550 companies across the country how they use and invest in AI. For the second, the College Hiring Outlook Survey, we looked at how 470 employers viewed entry-level hiring, workforce development and AI skills in candidates. These studies show both sides of the equation: those building AI and those learning to work with it.

AI is everywhere, but are people ready?

More than half of organizations told us that AI now drives daily decision-making, yet only 38% believe their employees are fully prepared to use it. This gap is reshaping today’s job market. AI isn’t just replacing workers; it’s revealing who’s ready to work alongside it.

Our data also shows a contradiction. While many companies now depend on AI internally, only 27% of recruiters say they’re comfortable with applicants using AI tools for tasks such as writing resumes or researching salary ranges.

In other words, the same tools companies trust for business decisions still raise doubts when job seekers use them for career advancement. Until that view changes, even skilled workers will keep getting mixed messages about what “responsible AI use” really means.

In the Data Integrity & AI Readiness Survey, this readiness gap showed up most clearly in customer-facing and operational jobs such as marketing and sales. These are the same areas where automation is advancing quickly, and layoffs tend to occur when technology evolves faster than people can adapt.

At the same time, we found that many employers haven’t updated their degree or credential requirements. They’re still hiring for yesterday’s resumes while, tomorrow’s work demands fluency in AI. The problem isn’t that people are being replaced by AI; it’s that technology is evolving faster than most workers can adapt.

Fluency and trust: The real foundations of adaptability

Our research suggests that the skills most closely linked with adaptability share one theme, what I call “human-AI fluency.” This means being able to work with smart systems, question their results and keep learning as things change.

Across companies, the biggest challenges lie in expanding AI, ensuring compliance with ethical and regulatory standards and connecting AI to real business goals. These hurdles aren’t about coding; they’re about good judgment.

In my classes, I emphasize that the future will favor people who can turn machine output into useful human insight. I call this digital bilingualism: the ability to fluently navigate both human judgment and machine logic.

What management experts call “reskilling” – or learning new skills to adapt to a new role or major changes in an old one – works best when people feel safe to learn. In our Data Integrity & AI Readiness Survey, organizations with strong governance and high trust were nearly twice as likely to report gains in performance and innovation. The data suggests that when people trust their leaders and systems, they’re more willing to experiment and learn from mistakes. In that way, trust turns technology from something to fear into something to learn from, giving employees the confidence to adapt.

According to the College Hiring Outlook Survey, about 86% of employers now offer internal training or online boot camps, yet only 36% say AI-related skills are important for entry-level roles. Most training still focuses on traditional skills rather than those needed for emerging AI jobs.

The most successful companies make learning part of the job itself. They build opportunities to learn into real projects and encourage employees to experiment. I often remind leaders that the goal isn’t just to train people to use AI but to help them think alongside it. This is how trust becomes the foundation for growth, and how reskilling helps retain employees.

The new rules of hiring

In my view, the companies leading in AI aren’t just cutting jobs; they’re redefining them. To succeed, I believe companies will need to hire people who can connect technology with good judgment, question what AI produces, explain it clearly and turn it into business value.

In companies that are putting AI to work most effectively, hiring isn’t just about resumes anymore. What matters is how people apply traits like curiosity and judgment to intelligent tools. I believe these trends are leading to new hybrid roles such as AI translators, who help decision-makers understand what AI insights mean and how to act on them, and digital coaches, who teach teams to work alongside intelligent systems. Each of these roles connects human judgment with machine intelligence, showing how future jobs will blend technical skills with human insight.

That blend of judgment and adaptability is the new competitive advantage. The future won’t just reward the most technical workers, but those who can turn intelligence – human or artificial – into real-world value.

Trump’s ‘golden age’ economic message undercut by his desire for much lower interest rates – which typically signal a weak jobs market

President Donald Trump seems to want to have it both ways on the U.S. economy.

On the one hand, he recently said the economy is in its “golden age” and referred to the U.S. as the “hottest country anywhere in the world.”

Yet at the same time, he has outright demanded that the Federal Reserve sharply slash interest rates to fuel economic activity. And his recently handpicked governor, Stephen Miran, has led the charge in pushing for a bigger cut than preferred by his new colleagues at the Fed.

When an economy is strong, central banks typically don’t cut interest rates and may even raise them to avoid spurring inflation. And so to support his argument for large cuts, Miran has played up “downside risks” to the economy and a weakening labor market, contrasting with Trump’s talk of a “golden age.”

Trump and Miran also seem to be ignoring the problem of inflation, which the president has said “has been defeated” and Miran considers close enough to the Fed’s target of 2%. Yet, inflation remains high and has been picking back up in recent months – one of the core reasons the Fed has taken a gradual approach to lowering interest rates.

I’m a macroeconomist, which means I study big-picture factors affecting an economy, such as interest rates.

It’s well known that lower rates spur faster growth, and of course all presidents want a stronger economy on their watch. But the Fed’s job when it sets interest rates is to deal with whatever reality the data shows – and make decisions accordingly.

Is the economy hot or not?

In the simplest terms, the Fed raises interest rates when the economy is “hot,” or inflation is above the Fed’s 2% target, and lowers them when there are concerns about unemployment.

At its most recent meeting, in September, the Fed lowered rates a quarter of a point, citing slowing jobs growth, and increased economic uncertainty. Trump nominee Miran was the only one of the 12 members of the Fed’s policy-setting committee to instead vote for a more aggressive half-point cut.

The only credible rationale for that large of an interest rate cut, in the face of still-high inflation, is by believing the labor market is incredibly weak. According to the Fed’s preferred measure, the personal consumption expenditures index, inflation has been accelerating all summer and was 2.7% at the end of August, well above the Fed’s 2% target.

There’s no doubt jobs growth has slowed considerably in recent months, but enough to completely ignore the risk of driving inflation higher? At this point at least, the Fed doesn’t think so.

And if the economy were in fact running hot, as the president claims, the Fed would have little choice but to keep rates flat or raise them, especially given elevated inflation.

Risks of following political whims

This situation gets at the heart of why central bank independence matters.

Trump’s efforts to influence the Federal Reserve have not been subtle and break with Congress’ intention to insulate the Fed from political manipulation. Besides pressing for big rate cuts, he has tried to fire a member of the Board of Governors over questionable allegations and mused about removing Fed Chair Jerome Powell.

The risks of following the wishes of a president in the face of what the data shows were starkly demonstrated in 2021, when Turkey’s president, Recep Tayyip Erdogan, fired the head of the country’s central bank. The central banker was pushing rates higher to tame inflation, which was at about 20%, but Erdogan demanded they be lowered. In response, Turkey’s lira plunged to record lows and inflation soared to over 70% in 2022.

Something similar could happen in the U.S. if Trump continues down the same path of meddling with the Fed. As a sign of how much Wall Street worries about this risk, a recent study estimated that if Trump followed through on his threat to fire Powell, the stock market could lose an estimated US$1 trillion as a result.

That’s because the Fed’s credibility rests on its ability to make decisions driven by economic evidence, not political expedience. That independence means policymakers must weigh data on inflation, jobs and growth rather than election cycles or partisan demands.

Justifying deeper rate cuts

Looking ahead to the Fed’s next meeting Oct. 28-29, policymakers face a delicate balancing act. With inflation still running above target and signs of slowing jobs growth, it needs to lower rates enough to prevent a downturn but not so low that inflation spirals out of control.

Traders are putting near-100% odds of two more quarter-point cuts this year, one on Oct. 29 and another in December. This would bring the Fed’s benchmark interest rate to a range of 3.5%-3.75% by the end of 2025, down from 4%-4.25% now.

Based on Miran’s own interest rate projections, he’s likely to again push for a larger cut of a half-point or more at both meetings, as he believes the Fed’s benchmark rate should be below 3% by the end of the year.

To me, as an economist, the only way a Fed acting independently could reasonably justify such a significant cut in rates in the next few months is if the unemployment rate begins rising steadily, with the economy clearly at risk of slipping into a recession.
