Visualising the Impact of Gentrification

UK housing construction volume.UK housing construction volume.

Graphic designer Herwig Scherabon has developed a book visualizing the impacts of gentrification in a number of cities in the United States and United Kingdom. Combining public access data and research with crisp visuals, Scherabon illustrates the spatial distribution of gentrification and examines the different issues at play.

Geography of Microbiomes

(a) Configuration of sampling site in Flagstaff office 1. This configuration was similar to those set up in all offices. Signs on the wall adjacent to wall sampling plate describe the project, as request that the materials not be touched. (b) Diagram of single sampling plate illustrating nine sampling swatches (circles) of three different materials, one row for tracking equilibrium relative humidity of the materials (Row #1), one row for infrequent sampling (Row #2), and one row for frequent sampling (Row #3). (c) Samples were collected from rows 2 and 3 of all sampling plates from three offices in each of our three cities in four intensive sampling periods over the course of one year. Coloring of sampling swatches in this figure illustrates the change in bacterial Phylogenetic Diversity over the year.(a) Configuration of sampling site in Flagstaff office 1.

Researchers have determined that geography seems to be the most influential factor in determining what kinds of microbial life would be found in a variety of local office settings.

Mapping the Consequences of American Urbanization and Stream Burial

A study has found that much of the area of urban America ­ particularly in the Great Lakes region (8.3% of urban area), the Arizona Sun Corridor (7.1%), and Northern California (10.9%) but elsewhere all over the United States (6.2% total) ­ are “urban stream deserts” in which a city is “riverless… due to the effects of human development and population growth”.
