Building inclusive cities is a protracted process which involves considering both the human dimension and the natural environment. Chapter 1, which introduces the book on inclusivity and the city, starts by giving an overview of the key concepts that underpin the discourse. This is done by giving the various definitions of inclusive cities and the anchors on which they rest. Hence, the social, economic and physical aspects of inclusivity are presented to some detail. These are drawn from the UN-Habitat with a focus on the urban agenda and are supported by narratives that revolve around sustainability. These are discussed in the context of the need to protect the natural environment in the face of climate change and with future generations in mind. At the centre of the discussion is the inclusion of vulnerable people who are always marginalised. Among them are immigrants who have to endure the pain of isolation in host societies. This, in reality, is the core of the book whose intention is to build cities that are inclusive of immigrants. The book discusses this in the context of selected Southern African countries and cities. Chapter 1 concludes by not only contextualising the topic but also setting the agenda for the whole book.
