Post-Conflict Security Sector Governance in Sierra Leone: Deficits as Inhibitors of National Development

Supervisors: Professor Stefan Wolff and Professor Paul Jackson

Research Group: British Politics Research Group

Solomon CaulkerSolomon’s research examines how security and development have interacted as a mutually-reinforcing nexus in Sierra Leone’s post-conflict political history.  Through the analytical lens of the security-development ‘nexus’, it is an exploration into how the security sector has/has not supported national socio-economic development while it has been consistently situated in post-conflict development and poverty reduction policy. While there is ample scholarly agreement on the normative interlinkages between the two concepts as well as being a widely-utilised policy approach, it is also argued that the two concepts are not seen to be working concertedly in practice; that there is inadequacy of evidence to provide it theoretical entrenchment. The study seeks to explore the nexus as the two concepts interact at policy, practice and scholarly research domains. Using Sierra Leone as a case study with particular utilisation of ‘process tracing’ to manifest co-variation and causal inferences, it juxtaposes the security and development realms in Sierra Leone through the exploration of the history of violent conflict, with particular examination of the role and governance of the security sector post-independence through to present time, bringing out the relationship between security and development policy and how the ‘securitization’ of development in the post-conflict era has manifested itself.
