Academic sins

This is probably the most common sin committed by academicians. Let me emphasize it: "Impenetrable Fog"! (I saw it at Drunkeynesian).

Huge Chinese internal migration

The Economist magazine has posted a very nice video on Chinese internal migration: The largest migration in history.




I keep trying to identify some similarities to the Brazilian case (here and here). A first moment with rapid and spatially concentrated urbanization/industrialization driving long-distance migration -  predominantly rural-to-urban migration patterns (1920s to 1990s). I would say China is now going under a similar process.

A second moment with: highly urbanized country, relative geographic dispersion of economic activities (although still highly concentrated ), a consolidated urban system with short-distance migration -  predominantly urban-to-urban migration patterns (1990s onwards).  I wonder if (and when) China will start to follow the same trajectory.....

We already have famous 'Laws of Migration' and a not so famous (international) migration transition theory. There must be somewhere a similar theory about internal migration ... If anyone knows more about it, please let us know!

Polycentric project for Moscow

The City Hall of Moscow has approved extending the city's borders to the south-west by 2014. According to the plan, the city territory will more than double. It seems they are seriously considering a more polycentric orientation (via Peter Gordon).

It is a curious remedy since Moscow is not highly monocentric when compared to other cities.

Simulations from the Early Days



Michel Batty has gathered some really interesting Early Animations of Urban Models.

One of these videos shows Jack Dangermond (co-founder of Esri) and Allan Schmidt* talking about the 'Harvard Laboratory for Computer Graphics and Spatial Analysis'. (more videos on GIS history here.)




*Allan Schmidt was responsible for what is probably the earliest "movie" of urban expansion. A SYMAP time lapse movie depicting growth of Lansing, MI 1850-1965.

AfriPop Project

AfriPop: demography aims to produce detailed and freely-available population distribution maps for the whole of Africa . It provides "detailed gridded spatial population datasets showing age composition by 5-year groupings and gender." (via devcondata). 

obs. I have just added this project to our Online Databases List, on the right of this page.
