This program looks at the development of Barcelona, a city dating to pre-Christian times, which grew slowly until the advent of the Industrial Revolution. After World War II, growth began to accelerate, the inner city became more crowded, the wealthier people moved to the suburbs, and real estate speculation and exploitation were rampant. Then the government moved in and planning began. The goal was to make urban life more pleasant: old, disused buildings were torn down, green spaces opened, advantage taken of the natural landscape of mountains, beaches, and the Mediterranean. These are luxuries that third-world cities cannot afford. Nevertheless, there are minimum standards of livability, and the program shows how the results of research can be applied to improve the allocation of scarce resources in housing, transportation, fuel consumption, air quality control, and waste disposal.
