S4 Ep46: Designing cities in developing countries

As cities grow and spread, the uses to which land is put, and the value of that land, will also change. The challenges of urban planning, construction and renewal are complicated.

Vernon Henderson and Maisy Wong of University of Pennsylvania explain to Tim Phillips how cities adapt, change and grow – and how that affects the lives and prospects of the people who live in them.
