4th ICC City Lab

A previous post made it clear that a 15-minute city ideally consists of a 5-minute walking zone, a 15-minute walking zone, also a 5-minute cycling zone and a the 15-minute cycling zone. These three types of neighbourhoods and districts should be developed in conjunction, with employment accessibility also playing an important role.
 
In the plans for 15-minute cities in many places around the world, these types of zones intertwine, and often it is not even clear which type of zone is meant.  In Paris too, I miss clear choices in this regard.
 
The city of Melbourne aims to give a local lifestyle a dominant place among all residents. Therefore, everyone should live within at most 10 minutes' walking distance to and from all daily amenities.  For this reason, it is referred to as a 20-minute city, whereas in most examples of a 15-minute city, such as Paris, it is only about <strong>the round trip</strong>. The policy in Melbourne has received strong support from the health sector, which highlights the negative effects of traffic and air pollution.
 
In Vancouver, there is talk of a 5-minute city. The idea is for neighbourhoods to become more distinct parts of the city. Each neighbourhood should have several locally owned shops as well as public facilities such as parks, schools, community centres, childcare and libraries. High on the agenda is the push for greater diversity of residents and housing types. Especially in inner-city neighbourhoods, this is accompanied by high densities and high-rise buildings. Confronting this idea with reality yields a pattern of about 120 such geographical units (see map above).
 
Many other cities picked up the idea of the 15-minute city.  Among them: Barcelona, London, Milan, Ottawa, Detroit and Portland. The organisation of world cities C40 (now consisting of 96 cities) elevated the idea to the main policy goal in the post-Covid period.
 
All these cities advocate a reversal of mainstream urbanisation policies. In recent decades, many billions have been invested in building roads with the aim of improving accessibility. This means increasing the distance you can travel in a given time. As a result, facilities were scaled up and concentrated in increasingly distant places. This in turn led to increased congestion that negated improvements in accessibility. The response was further expansion of the road network.  This phenomenon is known as the 'mobility trap' or the Marchetti constant.
 
Instead of increasing accessibility, the 15-minute city aims to expand the number of urban functions you can access within a certain amount of time. This includes employment opportunities. The possibility of working from home has reduced the relevance of the distance between home and workplace. In contrast, the importance of a pleasant living environment has increased. A modified version of the 15-minute city, the 'walkable city' then throws high hopes. That, among other things, is the subject of my next post.

Powering the future
Sustainable solutions for our digital dependency

Cloud computing does not take place in the sky. Gigantic data centers are popping up all around us, home to new AI services and Bitcoin mining operations that consume more energy than the entire country of the Netherlands annually. Code using Python & Java (the most popular) can use up to 45x times as much energy as other programming languages. Whether you are a programmer or user, our dependence on all this processing power is creating a new energy competition between our homes / businesses and our digital lives. What are some examples for sustainable development? Join us April 18th where we talk to industry pioneers that are developing serious solutions to solve our addiction to energy.

AGENDA:
17:00 Welcome drinks - Welcome drinks to break the ice and network a bit with fellow attendees.
17:30 Opening and Welcome - Pinch / Appsterdam
17:35 Kick-off Speaker - Tom Moran - Technology and Sustainability Strategy Consultant. Tom has been working in sustainability for over 30 years and technology for over 20 years. Tom is going to talk about why “the cloud” is not more sustainable, carbon footprints don’t matter, net zero targets are meaningless and why you should be skeptical of the AI hype machine.
Tom will also talk about what IT people who care about the environmental impact of their work need to understand and do to make a difference.
18:15 Food is served
19:00 Luisa García Montoya - Product Manager DX at AMS-IX. Luisa is passionate about leveraging technology to drive meaningful change. Drawing from her experience interacting with a diverse array of ISPs, telecoms, cloud providers, content delivery networks, and other participants involved in the digital ecosystem, Luisa will delve into the urgency for more sustainable code. The rise of ChatGPT/AI has created significant challenges for energy consumption. Recent laws and regulations are beginning to enforce standards to counteract these challenges. What aspects will programming practices need to account for? In her talk, Luisa discusses these challenges and opportunities, sharing some hard realities and examples, such as how mutualized infrastructures and data sharing can help save energy and money while also encouraging creativity in programming.
20:00 Closing and networking drinks.

Mobiliteit staat voor vrijheid, maar zorgt ook voor ongelijke lasten. Tijdens deze sessie onderzoeken we samen in een interactieve simulatie een systeem dat met 'mobiliteitskrediet' werkt. Wat zijn de effecten voor de samenleving? Biedt het kansen voor een eerlijkere verdeling om maakt het de ongelijkheid alleen maar groter?

Deze avond is onderdeel van een studie van de TU Delft, in samenwerking met AMS Institute en gemeente Amsterdam. Let op: Om deel te nemen aan deze avond in Pakhuis de Zwijger, heb je een werkende smartphone nodig.

NB. Deelname aan de sessie wordt beloond met een VVV-bon ter waarde van 10-euro.

Aanmelden kan via de website van Pakhuis de Zwijger https://dezwijger.nl/programma/mobiliteit-als-schaars-goed

Wanneer: Dinsdag 23 april
Hoe laat: 19:30-21:30
Waar: Pakhuis de Zwijger, IJzaal (Piet Heinkade 179, 1019 HC Amsterdam)
