Le rendez vous bi-hebdomadaire qui interviewe des chercheurs, des décideurs politiques et des praticiens pour mieux comprendre le métabolisme de nos villes et comment réduire leur impact environnemental d’une manière juste et contextualisée.Je suis Aristide Athanassiadis de Metabolism of Cities et dans cet épisode nous allons parler d’une thématique qui passe sous la majorité des radars mais qui relie des enjeux fondamentaux des villes l’alimentation d’un côté et l’assainissement des eaux de l’autre. Vous allez voir qu’aujourd’hui nous faisons du grand n’importe quoi au niveau des flux d’azote et de phosphore alors même que nous avons dépasser les limites planétaires qui permettent un futur sûr pour le futur de l’humanité. Si vous ne connaissez aux flux d’azote et de phosphore et pourquoi ceci sont fondamentaux pour les villes, ne vous inquiétez pas on a un invité qui arrive à vulgariser ces thématiques en seulement quelques minutes.Aujourd’hui, mon invité est Fabien Esculier, chercheur au Laboratoire Eau Environnement et Systèmes Urbains, une équipe de recherche commune à l’École des Ponts ParisTech et à l’Université Paris-Est Créteil. Il est Ingénieur des Ponts, des Eaux et des Forêts et a défendu sa thèse de doctorat en 2017 intitulée « Le système alimentation/excrétion des territoires urbains : régimes et transitions socio-écologiques ». Depuis 2015, il est le coordinateur du projet OCAPI ou Optimisation des cycles Carbone, Azote et Phosphore en ville.Dans cet épisode, nous parlons des trajectoires socio-écologiques des villes et comment le bouclage des flux d'azote et de phosphore et un enjeu différentes typologies de relations villes-campagnes, le rôle des acteurs publics et privés dans celles-ci mais aussi donnons plusieurs exemples concrets.Profitez de cet épisode et aidez nous à améliorer ce podcast en le partageant avec vos proches ou collègues, abonnez vous sur votre plateforme de podcast préférée (Youtube, iTunes, Spotify, Deezer or Stitcher) et laissez nous un commentaire 📝.👀 Youtube: https://youtu.be/nXeKUM8V2Xg👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg Hébergé par Acast.

Environmental Injustices of the Circularity Rift (Prof. Joan Martinez-Alier - UAB) - Circular Metabolism Podcast #40

📺 Welcome to the Circular Metabolism podcast 📺. Hello everyone and Welcome to the Circular Metabolism podcast, the bi-weekly meeting where we have in-depth discussions with thinkers, researchers, activists, policy makers and practitioners to better understand the metabolism of our cities and how to reduce their environmental impact in a socially just and context-specific way.Today we celebrate the 40th episode of the Circular Metabolism Podcast by covering an important topic which will confront the promises and imaginary of the circular economy with the ecological conflicts happening in the commodity extraction and waste disposal frontiers. Today, we will discuss about the entropic character of the industrial economy, about the circularity gap or rift, the environmentalism of the poor and about the world movement or movements of environmental justice. To talk about these topics, we have Joan Martinez Alier, an Economist that researched and published numerous articles and books on agrarian studies, ecological economics and political ecology. In 2017 he was awarded the prestigious Leontief Prize for Advancing the Frontiers of Economic Thought for his groundbreaking theoretical and applied contribution integrating ecological approaches with developmental and justice-oriented ones. In 2020, he received the Balzan Prize for Environmental Challenges research for his research on the world environmental justice movement (or movements) that can be illustrated by EJAtlas, a large and growing database of over 3,350 “ecological distribution conflicts” built up at ICTA UAB since 2012 (ejatlas.org).Enjoy this episode and before you go, please help us improve our podcast by subscribing to your favourite app including Youtube, iTunes, Spotify, or Stitcher and leave us a comment 📝 with your thoughts.👀 Youtube: https://youtu.be/n6ijVy977kg👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg#environmentalinjustice #circulareconomy #ecologicaleconomics Hébergé par Acast.

The Business of Less (Prof. Roland Geyer - UCSB) - Circular Metabolism Podcast #39

📺 Welcome to the Circular Metabolism podcast 📺. Hello everyone and Welcome to the Circular Metabolism podcast, the bi-weekly meeting where we have in-depth discussions with thinkers, researchers, activists, policy makers and practitioners to better understand the metabolism of our cities and how to reduce their environmental impact in a socially just and context-specific way.On today’s episode I will be discussing a topic that I’m not too familiar. It is loosely connected with consumption, companies and the pursuit of eco-efficiency or the win-win paradigm which assure us that companies can maximise profits and still protect the environment. As we will see this win-wins and sustainable business are a perhaps a pipe dream and that there might not be no such thing as green product. However, there is still a lot that we can do both at a company and a household level to reduce net environmental impact. To discuss about this topic I have Roland Geyer, Professor at the Bren School of Environmental Science and Management, University of California at Santa Barbara. Prior to joining the Bren School he held research positions at the Centre for Environmental Strategy (University of Surrey, UK), the Centre for the Management of Environmental Resources (INSEAD, France), working with top industrial ecologist. Roland has also recently published “The Business of Less: The role of companies and Households on a Planet in Peril” (show boo) which will make the basis of our conversation.Enjoy this episode and before you go, please help us improve our podcast by subscribing to your favourite app including Youtube, iTunes, Spotify, or Stitcher and leave us a comment 📝 with your thoughts.👀 Youtube: https://youtu.be/n6ijVy977kg👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg#business #ecoefficiency #industrialecology Hébergé par Acast.

The City as a Resource: the case of Earth (Anton Maertens) - Circular Metabolism Podcast #38

📺 Welcome to the Circular Metabolism podcast 📺. Hello everyone and Welcome to the Circular Metabolism podcast, the bi-weekly meeting where we have in-depth discussions with thinkers, researchers, activists, policy makers and practitioners to better understand the metabolism of our cities and how to reduce their environmental impact in a socially just and context-specific way.On today’s episode I want to switch gears a bit and leave theory and come back down to earth, pun intended. Ok bad pun aside, today I want to focus on a great initiative in Brussels that transforms excavated earth of construction sites into building materials. As such, they use probably one of the biggest waste flows of cities, which is by the way a local resource, and reduce the need for construction materials. To let us know more about this fascinating initiative I have Anton Maertens the Business developer at BC Materials.On this episode, we talk about how earth can be a local, low-tech, circular and carbon-neutral construction material. We learn how BC Materials went from a crazy idea to an urban manufacturing company making Brussels more circular. We learn about the challenges that they are facing as well as their vision for a future construction sector that would enable staying under the 1.5°C.Enjoy this episode and before you go, please help us improve our podcast by subscribing to your favourite app including Youtube, iTunes, Spotify, or Stitcher and leave us a comment 📝 with your thoughts.👀 Youtube: https://youtu.be/b4I1AhAnj68👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg#lowtech #circulareconomy #construction Hébergé par Acast.

Quelles relations villes-campagnes ? (Laëtitia Verhaeghe - Univ Paris 1 Panthéon Sorbonne) - Circular Metabolism Podcast ep.37

📺 Bienvenu.e au 37ème épisode du podcast Circular Metabolism: Quelles relations villes-campagnes avec Laëtitia Verhaeghe 📺.Bonjour et Bienvenu au Podcast Circular Metabolism. Le rendez vous bi-hebdomadaire qui interviewe des chercheurs, des décideurs politiques et des praticiens pour mieux comprendre le métabolisme de nos villes et comment réduire leur impact environnemental d’une manière juste et contextualisée.Je suis Aristide Athanassiadis de Metabolism of Cities et dans cet épisode nous allons parler d’un sujet fondamental pour le fonctionnement des villes. Comme nous allons le souligner plus tard dans notre discussion les villes sont loin d’être autonomes et autosuffisantes. Elles ont en effet besoin de s’approvisionner de ressources et traiter les pollutions tant solides, liquides qu’atmosphériques. Pour le faire elles ont besoin de territoires plus ou moins proches pour les aider. C’est précisément cette relation entre les villes et les campagnes que nous allons explorer aujourd’hui avec Laëtitia Verhaeghe.Laëtitia est doctorante ET bientôt docteure en Aménagement et Urbanisme à Université Paris 1 Panthéon-Sorbonne. Elle étudie les relations villes-campagnes portant sur les flux de matières et d’énergie renouvelable en France dans le cadre de la transition socio-écologique. On a pu échanger plusieurs fois lors de mon séjour de recherche dans son labo il y a maintenant 5 ans et je suis très curieux d’en apprendre plus sur ce sujet fascinant.Dans cet épisode, nous parlons des différentes typologies de relations villes-campagnes, le rôle des acteurs publics et privés dans celles-ci mais aussi donnons plusieurs exemples concrets.Profitez de cet épisode et aidez nous à améliorer ce podcast en le partageant avec vos proches ou collègues, abonnez vous sur votre plateforme de podcast préférée (Youtube, iTunes, Spotify, Deezer or Stitcher) et laissez nous un commentaire 📝.👀 Youtube: https://youtu.be/qWjBRyWymDQ👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg Hébergé par Acast.

From Steady State to Ecological Economics (Prof. Herman Daly) - Circular Metabolism Podcast #35

📺 Welcome to the Circular Metabolism podcast 📺. Hello everyone and Welcome to the Circular Metabolism podcast, I am your host, Aristide from Metabolism of Cities. In this podcast we interview thinkers, researchers, activists, policy makers and practitioners to better understand the metabolism of our cities and how to reduce their environmental impact in a socially just and context-specific way.On today’s episode I am very fortunate to receive one researcher that has helped laying the foundation for most of my colleagues and people we have received on this podcast work. He has co-develop and used two essential analogies that are essential for doughnut economics, post-degrowth, and even circular economy. These analogies are Steady State Economics and Ecological Economics. My guest today is Herman Daly which is emeritus Professor at the University of Maryland and was a senior economist at the World Bank for 6 years. He was the author of the book Steady-State Economics and the editor of the all-star anthology Toward a Steady-State Economy including authors such as Georgescu-Roegen, Boulding, Schumacher, Meadows and many others. He was also the co-founder and associated editor of the academic journal Ecological Economics. He received countless awards for his work.On this episode, we talk about how steady-state economics could be applied and helped to kickstart ecological economics but also about the controversial topic of population regulation (what is your opinion on that?).Enjoy this episode and before you go, please help us improve our podcast by subscribing to your favourite app including Youtube, iTunes, Spotify, or Stitcher and leave us a comment 📝 with your thoughts.👀 Youtube: https://youtu.be/91M622cvrLg👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg#ecologicaleconomics #steadystateeconomics #hermandaly Hébergé par Acast.

Heated Debates & Misconceptions about Degrowth (Timothée Parrique) - Circular Metabolism Podcast #34

📺 Welcome to the Circular Metabolism podcast 📺. Hello everyone and Welcome to the Circular Metabolism podcast, I am your host, Aristide from Metabolism of Cities. In this podcast we interview thinkers, researchers, activists, policy makers and practitioners to better understand the metabolism of our cities and how to reduce their environmental impact in a socially just and context-specific way.On today’s episode I want to go back to a topic that we briefly covered previously and get a bit more technical or encyclopedical. This concept is getting more and more popular although it is still very badly understood or used. I’m talking about the concept of Degrowth. To clarify some misconceptions about this topic I’ve invited Timothée Parrique, a researcher that holds a PhD from the University of Clermont Auvergne and the Stockholm resilience centre entitle “The political economy of degrowth”. Timothée is very active online where he collects and digests most work on degrowth but he also responds to media articles that cover degrowth both positively and negatively.On this episode, we talk about numerous facets of #degrowth, why this concept has created numerous heated debates and why it is stool widely misunderstood.Enjoy this episode and before you go, please help us improve our podcast by subscribing to your favourite app including Youtube, iTunes, Spotify, or Stitcher and leave us a comment 📝 with your thoughts.👀 Youtube: https://youtu.be/1-fuJYvJ7Sk👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg Hébergé par Acast.

The Metabolism of MegaCities (Chris Kennedy - UVic) - Circular Metabolism Podcast ep.33

📺 Welcome to the Circular Metabolism podcast 📺. Hello everyone and Welcome to the Circular Metabolism podcast, I am your host, Aristide from Metabolism of Cities. In this podcast we interview thinkers, researchers, activists, policy makers and practitioners to better understand the metabolism of our cities and how to reduce their environmental impact in a socially just and context-specific way.With today’s episode we will go amongst others back to the topic that we hold dearest to our hearts, urban metabolism. If you have ever explored this topic, one of the first pieces of information that you will encounter is the article “The changing metabolism of Cities” which quantified the energy, materials, water and waste flows from 8 cities co-authored by today’s guest Chris Kennedy. In fact, Chris has been one of the main driving forces for the renaissance of the urban metabolism field in the late 2000s. Chris is a Professor and the Director of Industrial Ecology Program at the University of Victoria. He has worked for over 20-years on strategies for addressing global climate change, drawing upon economics, technology, policy and industrial ecology perspectives. His research helped the development of a standard approach for city-wide greenhouse inventorying – as well as mitigation strategies. Holding qualifications in civil engineering, economics and business, he has conducted consulting work on sustainable infrastructure and cities for several national governments, as well as the World Bank and others. He previously served as President of the International Society for Industrial Ecology and author of The Evolution of Great World Cities: Urban Wealth and Economic Growth.On this episode, we talk about the renaissance of the urban metabolism field, on why Chris dedicated more than 10 years on this topic, what were some of the learnings he encountered and what are his current research interests.Enjoy this episode and before you go, please help us improve our podcast by subscribing to your favourite app including Youtube, iTunes, Spotify, Deezer or Stitcher and leave us a comment 📝 with your thoughts.👀 Youtube: https://youtu.be/5qfo8EXbtvE👂 iTunes: https://podcasts.apple.com/be/podcast/circular-metabolism-podcast/id1455115320👂 Stitcher: https://www.stitcher.com/show/circular-metabolism-podcast👂 Spotify: https://open.spotify.com/show/13qH9Oj4b0yF0dBidGAdFR👂 Google: https://podcasts.google.com/feed/aHR0cHM6Ly9mZWVkcy5hY2FzdC5jb20vcHVibGljL3Nob3dzLzYwMWMyYzNlODg4NzQ3NjIyYmY5MzRlNg Hébergé par Acast.
