In recent periods, West Africa has emerged as a hot spot for criminal activities, especially drug smuggling, human trafficking and international terrorism. Its geographical location on the Atlantic Ocean makes this region a transit hub between Africa, Europe and the Americas. Hence, improving security in this area is not only a matter of regional, but also global interest. Implemented by INTERPOL with funding from the European Union, the West Africa Police Information System (SIDAO/WAPIS) Programme aims at strengthening information exchange and coordination among the region’s law enforcement agencies (Police, Gendarmerie, Customs, Immigration Services, etc.) in the 15 ECOWAS Member States, Mauritania and Chad, supporting their efforts in preventing and combating transnational organised crime and terrorism.
