Book excerpt: "For a number of years, the Sahel has been faced with a series of threats, the most emblematic of which are Islamist terrorism, illegal trafficking and organized crime. These threats have contributed to the destabilization of the region and accentuated the weakness of certain States. This situation aggravates the climate of insecurity and further accentuates the risks of instability, which hardly promotes the socio-economic development of Sahelian countries. In this environment, Jihadist groups and organized crime networks flourish. These networks develop with the complicity or participation of local actors, who profit from illicit traffics in these areas where State presence is limited and States have difficulty controlling their own borders ... Through a multidisciplinary approach taking account of socio-political and economic aspects, this study seeks to clarify the nature of the relationships between organized crime and terrorism and to analyse the impact of their activities on States and local communities in a context of major political and social upheaval in the Sahel"--Back cover.
