The numbers of piracy incidents around the Horn of Africa and Gulf of Guinea in recent years have increased due to breakdown of good governance in onshore of Somalia, Nigeria and some other African countries. This paper examines the causes of piracy in the Nigerian maritime domain. It also appraises the impact of piratical activities on the economic development of the nation as well as governmental efforts to curb the scourge. It argues that the development of an effective business plan by pirates and the initial lackadaisical attitude of the Nigerian government to deal with the situation are major factors responsible for the increase in the criminal underworld of the Nigerian maritime domain. The paper recommends effective Surface Surveillance System, Bilateral Arrangement, Regional Maritime Awareness, among others as panacea to tackle the menace of piracy in Nigeria.enCriminalUnderworldMaritimeDomainTrans-boundary HarmsExegesisMaritimeChallengesBook chapter
