Measuring cities’ fragility: an interactive mapping tool.

Launched in 2016 World Economic Forum in Davos from Igarapé Institute in collaboration with the World Economic Forum, the United Nations University, 100 Resilient Cities, XSeer and Canada’s Global Affairs, fragile cities  is an interactive tool that allows to visualize cities in terms of their fragility. The platform includes information on over 2,100 cities with populations of 250,000 or more. Cities were graded across 11 variables at the urban scale including population growth, inequality, unemployment, access to electricity, pollutions, exposure to terrorism, homicide rates and reported conflict events.and given a score between 1 (low fragility) and 4 (high fragility).

Besides, the evolution of urban fragility parameters in the period 2000-2015, and projections for the future, can be reconstructed by clicking on the dots.Below you can see, for example, the evolution of the fragility index for Lausanne:

Albeit cities’ fragility can be argued to be a much more multidimensional and complex concept, fragile cities is an interesting exploratory tool which could be useful to address issues of urban resilience.

Further information can be accessed here.

Transitflow: visualizing public transport routes in space and time

Columbia University student Will Geary created an instrument to visualize public transport flows through the 24 hours of the day.

For example, below you can see an example of visualization for the San Francisco Bay Area, in which small colored dots represent each a different mean of public transport (bus, subway, train, ferry..)

Want to know more?

Here you can get detailed information on how these maps where made and get the tools to create your own visualization for the city you’re interested in.

An incredible map of which countries e-mail each other, and why?

The Internet was supposed to let us bridge continents and cultures like never before. But after analyzing more than 10 million e-mails from Yahoo! mail, a team of computer researchers noticed an interesting phenomenon: E-mails tend to flow much more frequently between countries with certain economic and cultural similarities.

see the paper in Washington Post

ORBIS: the Stanford Geospatial Network Model of the Roman World

The system calculates the distance from a city to another one, according to faster path, or lower cost.

https://orbis.stanford.edu/

Go to “Mapping ORBIS”, It draws the path and create many different maps and graphs (in “Map gallery”). It’s a pity that the Emperors did not have this system 🙂

Art and Geography

Three years ago, a friend of mine who is a genius artist (Catherine Bolle), asked me to do geography on her biography. She told me many things about her life, during some few sundays afternoon in the Beaurivage Hotel in front of the lake in Lausanne. It took one year to build the data and think about the pictures to produce. Then to build them and interpret with a nice text.
