Boundaries and Conflict in the Mano River Region of West Africa
Silberfein, Marilyn; Conteh, Al-Hassan - In: Conflict Management and Peace Science 23 (2006) 4, pp. 343-361
The porous and contestable features of African boundaries are two interacting themes that are closely linked to the emergence and spread of conflict in Africa in the last decade. This study uses the Mano River Region—Sierra Leone, Guinea, Liberia, and Ivory Coast—to illustrate how...
