The current #water crisis in Iran is the most severe on the planet at the moment, threatening not just the people but the legitimacy of the government. www.theguardian.com/world/2025/n...

My daughter is going to check it out now. She loves this stuff.

One of Iran’s greatest exports is water experts. Some are cited in this article about the water crisis unfolding there today. www.nbcnews.com/world/iran/i...

Is it ever nice to see the sign for the airport. My brother-in-law figured out how to cycle there to catch a flight, but taking the train is far more practical. 😁

I'm so happy they mentioned Trois-Rivières as having invested in green infrastructure to reduce overflows! Here's our paper in collaboration with Trois-Rivières: iwaponline.com/bgs/article/...

Nice. Félicitations à Yoshua!

I missed it by a day. Spectacular. Too much cloud cover in Montréal tonight

Today in the globe and mail

Extremely enjoying reading "The Big Road" by Earl Swift about the creation of US's interstate system which (good) replaced dangerous intercity highways & (bad) destroyed entire city neighbourhoods and urban way of life for millions of people. Montreal still healing from urban "autoroutification".

It cost tens of millions of dollars to get autoroute runoff out of our drinking water. It should never have been built that way in the first place. So much bad design from that era that later needed fixing.

I went to Catherine McKenna’s book launch at @joiedelivresmtl.bsky.social last week. She mentioned this podcast if I remember correctly. I’ll check it out.

Terrible idea.

Despite all the universities in Montreal, « the percentage of residents ages 25 to 64 in Montreal with a university degree rose from 33 per cent a decade ago to 43 per cent in 2024. But in Toronto and Vancouver, it rose to more than 50 per cent, catching up to the rate in the U.S. cities »

We had some fun comparing Ontario and Québec source water protection approaches for microbial risks in a transboundary river. repository.tudelft.nl/file/File_3f...

This is Ontario’s source water protection legislation. There is room for improvement, but it needs to be done right. I’m somewhat skeptical given the Ford government’s track record.

Je ne connaissais pas cette histoire. C’est mieux maintenant, même si notre système de CÉGEP actuel empêche de nombreuses personnes qualifiées de continuer en sciences.

Avec mon collègue Sébastien Sauvé. Nous avons étudié les cyanotoxines au Petit lac Saint-François. Il n'y a pas un excès de cas de SLA en Estrie, mais de nombreuses questions demeurent pour les familles touchées. www.frontiersin.org/journals/wat... ici.radio-canada.ca/tele/enquete...

Bonne nouvelle! La petite Yoshi a retrouvé sa famille. Merci pour vos partages.

This clip begins with the people marching behind the Eötvös Loránd banner. My father-in-law is one of them. He later fled Hungary with Béla Király and a few other men, crossing the Austrian border (walking backwards) where his cousin was a border guard.

Une EXCELLENTE nouvelle! On va la prendre.

La famille du chien n’a toujours pas été trouvée. Malheureusement pas de micropuce.

Ensemble Montréal proposing to remove bike lanes in Parc-Extension. That’s exactly the kind of thing I’m worried about: sabotaging up-and-coming bike-friendly neighbourhoods.

Un petit chien perdu se promenait dans la rue seul dans Outremont sans collier ni laisse. Il est extrêmement mignon et gentil, et veut retrouver sa famille. Il est en sécurité chez nous en attendant. Signalé à la SPCA de Montréal.

Les couleurs de ce matin. #Outremont

⚡️ « Le constat : le système d’éducation du Québec tend à exacerber les inégalités alors qu’il devrait contribuer à les réduire. » —Mylène Drouin, directrice régionale de Santé publique à Montréal

Céline Forget's volunteers knocked on my door on Saturday. It motivated me to write this piece on sustainable transportation for all children in Outremont before advance polls open next Sunday. Hornet's nest kicked. Election Day is November 2nd. Vote. medium.com/@sarahdorner...

Québec's Ministry of Economy, Innovation and Energy invited Philippe Aghion to give a talk to researchers. I was grateful for the invitation. Fascinating stuff. I hope he doesn't mind that I recorded a few seconds - here he introduces his model for which he won the Nobel Prize.

The Economist's correspondent stood on a street corner on Montreal's rue Saint-Denis street and counted bicycles.

Un niveau d'eau faible par dessus une prise d'eau potable peut nuire au pompage, mais c'est typiquement la demande qui a une plus grande influence sur la vulnérabilité.

One of our projects with a small community uses smart street lights to send data on well water levels to monitor sustainable water use, so I pay attention to other kinds of smart systems.

Smart traffic lights are in Projet Montréal’s platform. I couldn’t find it in Ensemble Montréal’s. projetmontreal.org/nouvelles/de...

Dismantling old dams & restoring natural ecosystems. "Démantèlements de vieux barrages au Québec " www.lapresse.ca/actualites/e...

Victoriaville recently removed the dam on the Bulstrode river that flows through the town. Fun fact: In 1875, the Bulstrode River and the Nicolet River were recognized as one of the best rivers for salmon, which weighed an average of 18 to 24 pounds. Then came the dams and it was bye-bye salmon.

Quelque part dans mes vieux dossiers, il y a une demande de subvention (non financée) pour étudier le démentèlement de barrages au Massachusetts.

A bit of positive news for your friday — my colleague @enveco.bsky.social explains how Canada's electricity sector flipped the switch on emissions. @climateinstitute.bsky.social #ClimateChange #Emissions #NetZero

As a Montrealer, this makes me so proud! 🙌 “Though other cities offer bike-sharing programs, “Montreal revolutionized the trend,” TIME wrote, calling Bixi’s technology “the backbone” of bike-sharing services in cities including London and New York.” montrealgazette.com/news/bixi-bi...

La @villedemontreal.montreal.ca rayonne par son réseau cyclable & @biximontreal.com 🚲✨ " #Montreal ’s bike boom [...] is highly energy-efficient, costs almost nothing, reduces congestion and pollution, and obviates the need for huge car parks" #bikemtl #velomtl #urbanism #polmtl #biximtl #mtlpoli

A must read thread responding to the most bizarre “critique” I’ve ever seen of wealth taxes. The article reads pretty much like a verbatim copy of @patmillscanada.bsky.social ‘s central messaging, while telling us to cut a check to the government and to shut up 🤷🏼

📢📢📢

En tout cas, il y en a un au MBAM, à côté d'autres inventions de Michel Dallaire, si je me souviens bien Mais ça fait vraiment longtemps que je n'ai pas visité le MBAM

Je ne suis pas allée récemment, mais est-ce qu'il y a un bixi au Musée des sciences et de la technologie du Canada?

Though bike lanes take up less than 2% of road space in Montreal (cars get 80% and pedestrians the balance), they are a hot issue in its mayoral election on November 2nd. Soraya Martinez Ferrada, the leading opposition candidate, wants to pause new bike lanes and remove some if the cause anxiety 4/

Forget EVs. Cycling is revolutionising transport This week we have a change of pace in the International pages of @economist.com we have a great piece by @dlknowles.bsky.social where he takes a look at how pedal power is booming around the world, but also spinning up a new culture war. 1/
