Arguably the least discussed root cause of internal displacement, harmful practices are a prevalent concern in many African societies. The explicit mention of harmful practices is one of the many innovations of the Kampala Convention and reinforce its forward-looking, context-specific focus on Africa. This article argues that the convention has an absolute prohibition of harmful practices. This is an important starting point from which to discuss the content of states’ obligation to set measures for preventing harmful practices. However, in the event that displacement occurs due to these practices, it is important that protection, humanitarian assistance and durable solutions are provided. This article argues that states must set measures for ensuring that non-state actors are held accountable in the event that they orchestrate harmful practices. In fostering compliance, this article argues that there is an important role for institutions beyond the state, particularly those emphasized under article 14 of the convention.

The scholarly discourse on social norms in the tradition of Thomas Schelling (1960) often makes a sharp distinction between social norms and social conventions. In attempting to apply that distinction to actual practices and to teach it to practitioners and students I encountered frequent difficulties and confusions, and finally concluded that it is untenable. I recommend a return to some version of Ullman-Margalit’s (1977) distinction between social norms of cooperation and social norms of coordination. Social norms, I say, are distinguished by beliefs in a relevant group that the rule is typical among them and approved of among them. I describe four ways that social norms of coordination, including conventions of social meaning, are influenced by social approval and disapproval. I contend that the effort by Southwood and Eriksson (2011) to show that social conventions and social norms are essentially different breaks down because their conception of social norms is overly moralized. I present a more social conception of social norms that does without the regnant distinction between “social norm” and “social convention” and instead allows for social norms of cooperation, social norms of coordination, and other kinds of social norms.
