Issues which the lecture addresses

Over the last 30 years, GC have developed worldwide in cities in the global north and south. The expansion of this type of housing responds to structural causes, such as increasing inequality and a polarisation process, and also to individual preferences. In addition, GC have positive and negative impacts that can be analysed according to several dimensions: spatial, economic, political and social.

Short analysis of the above issues

The analysis of GC development is organised in three main areas: First, a discussion of the characteristics of GC. Second, an analysis of why GC have developed over the last 30 years. The causes include structural causes and subjective preferences. Third, an exploration of spatial, economic, social and political consequences of the expansion of GC, showing both the negative and positive effects of this type of residential development. Finally, the conclusion of the lecture addresses the implications of GC development for planning.

Propositions for addressing the issue

The discussion of the characteristics of GC is essential as there are several definitions and this has an impact on how we understand the phenomenon, and also on how planning frameworks can addressed their growth. There are some elements that create controversy in the definition of GC. * GC constitute the main type of housing development from the formal system (usually encouraged by the private sector, with the endorsement of the government). * There are important positive and negative impacts of the development of GC. In particular, it is important to consider them in relation to the type of cities we want to live in and in particular, on the relationship with SDG11 and the New Urban Agenda * Urban planning has a crucial role and should use some instruments to minimise the negative impacts of GC and maximise their positive impacts. All these points will be illustrated with examples.
