590 cities population data visualization


The stack flow above by Barcelona design concern Bestiario depicts the 590 most populated cities sorted column by their population between 1950 and 2010 in 5 year intervals, and projected for 2015, 2020, 2025. Cities’s colors are generated from their geographic coordinates, with the hue varying with longitude, as the below image shows (cirlces areas are proportional to cities population in 2010). The interactive version is quite a data dump – I wish you could isolate just one city and turn off the rest.

E. chromi – color-coded bacteria

E. chromi is a collaboration between designers and scientists in the new field of synthetic biology. In 2009, seven Cambridge University undergraduates spent the summer genetically engineering bacteria to secrete a variety of coloured pigments, visible to the naked eye. They designed standardised sequences of DNA, known as BioBricks, and inserted them into E. coli bacteria.

Each BioBrick part contains genes selected from existing organisms spanning the living kingdoms, enabling the bacteria to produce a colour: red, yellow, green, blue, brown or violet. By combining these with other BioBricks, bacteria could be programmed to do useful things, such as indicate whether drinking water is safe by turning red if they sense a toxin. E. chromi won the Grand Prize at the 2009 International Genetically Engineered Machine Competition (iGEM).

London Low Emission Zone

Low Emission ZONE

News to me: besides having a Congestion Charge zone, London also has a Low Emission Zone

The Low Emission Zone (LEZ) was introduced in 2008 to encourage the most polluting heavy diesel vehicles driving in the Capital to become cleaner. The LEZ covers most of Greater London. To drive within it without paying a daily charge these vehicles must meet certain emissions standards that limit the amount of particulate matter (a type of pollution) coming from their exhausts.

The low emission zone started operating on 4 February 2008 with phased introduction of an increasingly stricter regime until 3 January 2012, and as shown below, covers pretty much all of metropolitan London (the congestion charge zone is shaded orange).

The LEZ is monitored using Automatic Number Plate Reading Cameras to record number plates checking vehicles against the records of the Driver and Vehicle Licensing Agency to enable Transport for London to pursue owners of vehicles for which the charge has not been paid.

It would come as little surprise to my reader that I am a proponent of the London Low Emission Zone; much like the congestion zone, the low emission zone prices (ever so bluntly) an externality: particulate matter which is being dumped into the air by commercial vehicles. A charge both prices in this externality and will drive innovation to reduce vehicle emissions.

I also love the graphic sensibility of the advertising and communication on their website and in collateral, examples shown below.

Flyover Farm by Fresh & Local

Flyover Farm Sketch

Via Mumbai Boss, comes the story of Flyover Farm by Fresh & Local which is aiming to add farms on top of existing Mumbai buildings, and they have a Kickstarter:

Fresh & Local is a movement to facilitate urban farming in Mumbai. We started in the spring of 2010, in reaction to the lack of fresh and organic produce, and the lack of resources and support for urban farming in the city. We research and develop best practices, design gardens and garden products, host gardening workshops and work in partnership with NGOs and individuals to set up kitchen gardens across the city.

Fresh and Local’s Flyover Farm project is a natural progression and culmination of the work currently being carried out.

Flyover Farm Existing

This is all really interesting, but seeing the existing building stock which is generally of poor construction and knowing how much soil is required to grow fruit and vegetable plants, I fear that not many building can support the weight of these roof farms. I applaud the project, since we have lots of roof space in Mumbai, and the quality of vegetables will undoubtably be better than the ones grown on the sides of the suburban railways.
