Maritime security

Maritime security in the Gulf of Guinea consists of 18 sovereign states. Multiple institutional mandates address maritime security in the Gulf of Guinea: The Economic Community of West African States (ECOWAS) and the Economic Community of Central African States (ECCAS). Additionally, maritime security in the Gulf of Guinea is also addressed by the Gulf of Guinea Commission (GGC). Maritime security in the Gulf of Guinea is characterised not only by piracy but by a myriad of maritime crimes despite piracy often dominating the conversation on maritime security. According to the ‘Priority Paper for the Danish Efforts to Combat Piracy and Other Types of Maritime Crime 2019-2022’ piracy and maritime crime are defined as follows:

''Piracy'' can be defined as any illegal act of violence, detention or depredation committed for private ends at high seas against another ship or aircraft.Ministry of Foreign Affairs of Denmark. (2019). Priority paper for the Danish efforts to combat piracy and other types of maritime crime 2019-2022. Copenhagen: Ministry of Foreign Affairs of Denmark. Maritime crime may include armed robbery at sea, trafficking of humans or smuggling of illicit goods, drugs and weapons,
illegal fishing Illegal, unreported and unregulated fishing (IUU) is an issue around the world. Fishing industry observers believe IUU occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries. Illegal fishing takes p ...
, fuel theft and more.

The other notable crimes in the Gulf of Guinea are illegal fishing, kidnap for ransom, drug trafficking and oil-bunkering.Ministry of Foreign Affairs of Denmark. (2018). Gulf of Guinea Maritime Security Programme, 2019-2021. Copenhagen: Ministry of Foreign Affairs of Denmark. Illegal oil-bunkering consists of the attacking of vessels transporting oil and transferring the oil to the thieves’ own vessel. After which the oil is sold in local and international markets. Kidnapping for ransom is one of the most prevalent maritime crimes in the region. Between 2018 and 2019, the number of crew members that were kidnapped in the Gulf of Guinea increased by 50%, leading the region to account for 90% of global kidnappings at sea.
