Maritime security is an umbrella term informed to classify issues in the maritime domain that are often related to national security, marine environment, economic development, and human security. This includes the world's oceans but also regional seas, territorial waters, rivers and ports, where seas act as a “stage for geopolitical power projection, interstate warfare or militarized disputes, as a source of specific threats such as piracy, or as a connector between states that enables various phenomena from colonialism to globalization”. The theoretical concept of maritime security has evolved from a narrow perspective of national naval power projection towards a buzzword that incorporates many interconnected sub-fields. The definition of the term maritime security varies and while no internationally agreed definition exists, the term has often been used to describe both existing, and new regional and international challenges to the maritime domain. The buzzword character enables international actors to discuss these new challenges without the need to define every potentially contested aspect of it. Maritime security is of increasing concern to the global shipping industry, where there are a wide range of security threats and challenges. Some of the practical issues clustered under the term of maritime security include crimes such as piracy, armed robbery at sea, trafficking of people and illicit goods, illegal fishing or marine pollution. War, warlike activity, maritime terrorism and interstate rivalry (such as the Territorial disputes in the South China Sea or conflict in the Strait of Hormuz) are also maritime security concerns. While a concern throughout history for nation states, maritime security has evolved significantly since the early 2000s, when in particular concerns over terrorist attacks on port facilities sparked interest in security in the maritime domain and led to the creation of the International Ship and Port Facility Security Code. The ISPS Code is enforced through Chapter XI-2 of the SOLAS Convention. Most littoral states and international organisations have also outlined maritime security strategies. It is in particular piracy in Southeast Asia, off the coast of Somalia and in West Africa which has triggered recognition for the detrimental effects of maritime insecurities for economic development, human security as well as the environment. Maritime security is often transnational and goes beyond the maritime domain itself (see liminality). It is characterized as being cross-jurisdictional and/or highly jurisdictionally complex.
History of maritime security Historically, the sea has been subject to different concepts of law and power. The term mare nostrum (our sea in Latin) was coined by the Romans in 30 BC to 117 AD as a term to describe its control of the Mediterranean Sea. From this concept of the sealing of a sea, the legal concept of mare clausum (closed sea in legal Latin) was developed during the age of discovery between the 15th and 17th century. The sea became a restricted space, organised between Portugal and Spain. Maritime activity was exclusively reserved for the enhancement of national security through naval military. In 1609, Hugo Grotius, a Dutch philosopher and jurist, published the book mare liberum where he introduced the concept of the free sea (mare liberum is translated to free sea in legal Latin). In his book, Grotius laid out the foundation of the freedom of navigation at sea. The sea was seen as international territory, where every nation was free to conduct trade. Grotius’ concept of the free sea was superseded by the United Nations Convention on the Law of the Sea (UNCLOS). This international agreement first came into effect in 1958 as the Convention on the High Seas (UNCLOS I). The most recent agreement is UNCLOS III, which is active since 1994. It now includes various zones and jurisdictions, including internal, territorial, and archipelagic waters. It further defines the exclusive sovereign waters of a state called contiguous zone, and the exclusive economic zones (EEZs) in which a state has the sole exploitation rights of resources like oil and fish. The latter can be extended by the continental shelf, a natural prolongation of the territory of the respective state. Maritime security has until then been mostly concerned with interstate naval conflicts and piracy at sea.
