Published by ODI/ALNAP, this Good Practice Review is structured into four chapters. Chapter 1, on context, sets the scene. It describes ways of seeing the city (there are many; this section presents three). The chapter then discusses four particular threats: naturally-triggered disasters, climate change, conflict and violence. The next sections look at urban displacement and vulnerability – cities are homes to extremes of wealth and poverty, and the poorest are almost always the most vulnerable. The chapter ends with a discussion of actors in the urban space associated with the humanitarian ecosystem.
