This week in class, we talked about the layout of a city as
well as the many systems within a city and how they resemble very closely the
systems that occur naturally in nature. We discussed the spatial structure of a
city. This includes the spatial distribution of the population, the
distribution of real estate prices, and the distribution of wages and incomes
over space. We looked at how the population was distributed throughout a city
and the reasons behind this distribution. The primary reason being that density
gradients flatten with income. This
means that the majority of the people in any major city live just a few
kilometers from the city center due to the fact that land rent values increase
toward the center of a highly urbanized area. A paper that discusses many of these
points can be found at http://alain-bertaud.com/AB_Files/Spatia_%20Distribution_of_Pop_%2050_%20Cities.pdf

Another subject of our class discussions this week was urban
ecology or a field that deals with the interaction between organisms in an
urbanized community and the community itself. We talked about how cities are
similar in many ways to nature in the sense that the flow of matter and energy
through the ecosystem is comparable to the way that they move through a city or
urban community. A blog dedicated to urban ecology and learning about and
education residents about their community and their physical environment can be
found at http://blog.urbanecology.org/
