Seminário NOVAFRICA: Oliver Vanden Eynde, Paris School of Economics — “Cooperação entre exércitos nacionais: evidências das regiões fronteiriças no Sahel”

Evidência de um estudo na região do Sahel mostra como a cooperação militar transfronteiriça influencia a dinâmica de conflitos em regiões frágeis.

“Cooperation between National Armies: Evidence from the Border Regions in the Sahel.”

Abstract

The effectiveness of security operations often depends on cooperation between national armies. Such cooperation can be particularly important when international borders are porous and armed groups can operate across borders. We investigate how the creation of an international armed force that could operate across international borders (the G5-Sahel Joint Force), together with improved communication between national armies, affected conflict dynamics in the Sahel region. Relying on a regression discontinuity design, we find that the G5 mission lowered the intensity of conflict locally in its zone of operation, especially along border segments more porous due to their geographical features or ethnic composition. Further analysis of geographical conflict propagation patterns indicates that the G5-Sahel force facilitated security operations in border areas.
