In the last lecture we will discuss a few themes that capture the dynamics of city building process in contemporary times. In the previous lectures we have seen how urban design is a product of societal forces as well as conscious planning activity. The different considerations behind the city building process, as Paul Knox points out, have varied from mythology, religion, military strategy, national identity, public health, economic efficiency and sustainability. In contemporary times an important theme that emerges is the development of the city as a site of consumption. The cities have changed from sites of production to consumption and they have got increasingly divided between the gentrified sections and the unplanned quarters. In this lecture we talk about the themes of consumption and social exclusion. The contemporary transformation of Mumbai following the logic of the second-circuit of capital will also be discussed here.
