What is the Science of Cities and how does it relate to scaling?

The Science of Cities is a research framework led by experts like Luís Bettencourt and Geoffrey West that views urban environments as biological entities. By applying principles of biological scaling, researchers investigate whether cities follow predictable rules of growth similar to living organisms. This approach suggests that as a city expands, it doesn't just get larger; it follows specific mathematical patterns that govern how energy and resources are used by the population.

How does Kleiber’s Law apply to urban growth and infrastructure?

Kleiber’s Law is a biological principle stating that larger organisms are more energy-efficient, a concept known as sublinear scaling. In the context of the Science of Cities, this means that as a city doubles in size, it does not require a double amount of infrastructure. Instead, it becomes more efficient, requiring fewer resources like gas stations per person because the increased density allows for shared utility and closer proximity.

Who are the key researchers behind the study of city scaling?

The foundational research into the scaling and growth of cities was led by Luís Bettencourt and Geoffrey West starting around 2007. They moved beyond viewing cities as mere collections of buildings, instead analyzing them through the lens of biological scaling. Their work compares the metabolic rates of animals, such as mice and elephants, to the functional efficiency of major metropolitan areas like New York and San Francisco.

What is sublinear scaling in the context of city efficiency?

Sublinear scaling refers to the phenomenon where a system becomes more efficient as it grows in size. In biology, if you double a mammal's size, it only needs about 75% more food to survive. The Science of Cities applies this to urban growth, finding that infrastructure like roads and utilities scales sublinearly, meaning larger cities actually save on energy and resources per capita compared to smaller ones.

Input question

I would like to about the study of Bettencourt, Lobo, Helbing, Kuhnert & West, “Growth, innovation, scaling, and the pace of life in cities” fra PNAS i 2007 and possible other studies confirming this or rejecting it.
