Why are civil society organizations so often unable to make a difference during the transition to peace? I argue that the contributions of local civil society organizations and women's organizations to postconflict peacebuilding should be understood in terms of the networks that emerge during the peacebuilding process. Horizontal network conditions are essential for successful postconflict reconstruction. Yet external actors often implement policies that strengthen hierarchical links at the expense of such horizontal networks. To explore the types of networks that emerge in postconflict reconstruction, I use semistructured interviews conducted in Liberia. The evidence suggests that emerging horizontal networks are more robust in areas where local communities and women have a tradition of organizing. However, these networks remain fairly unstable. The assistance is mostly channeled centrally, strengthening hierarchical ties and leading to distortions in the distribution of resources.
