Best Practices: Maritime Domain Awareness

Effective knowledge production about activities at sea, also known as Maritime Domain Awareness (MDA), is one of the backbones of successful maritime security governance on both national and regional levels. Establishing a centre that integrates data on maritime activity and analyses it is a priority. Such centres share information between agencies on both national and regional levels. In many countries, a national centre also integrates search and rescue, as well as the monitoring of fisheries.

MDA implies monitoring activities at sea, fusing information provided by different agencies and analysing this data in order to identify patterns, trends, anomalies and suspicious activities. This knowledge is not only important for policy formulation, but also to increase the efficacy of maritime operations, preventive patrols and inspections and to improve responsiveness to maritime incidents. Quick reaction capabilities are vital in the marine environment to prevent environmental disasters and in search and rescue situations, and to ensure the timely arrest of maritime crime suspects.

MDA has also been identified as one of the means to create a culture of cooperation between maritime security agencies. MDA can nurture trust and confidence between agencies that have divergent organisational interests and cultures, but also different habits of addressing issues. Trust is both an outcome of and precondition for successful MDA. To develop trust, MDA centres need to facilitate the frequent everyday interactions between agencies and prove that their work makes a recognisable difference.




MDA is often primarily understood as a high-tech challenge of installing and integrating sensors such as radar stations, developing databases and anomaly-detection algorithms, or visualising data. Human dimensions and analytical capacities are equally vital, however. Data can be collected from human sources rather than sensors, whether from informants of the broader maritime community such as fishermen, or from public sources like social media or the news. High-tech systems are not only expensive, but tend to come with high maintenance costs. Developing MDA capabilities therefore needs to identify the right mix between high- and low-tech.

A model that has been successfully introduced by several countries is that of an MDA centre that fuses data from sensors and human sources through a central database and is staffed with seconded personnel from each maritime agency. Developing the right standard operating procedures is key to overcome the barriers of information sharing (see box above). Such centres can also contribute to public awareness and cooperation between all users of the sea, for example through newsletters, frequent events that bring together the broader maritime security community, or coastal community engagement programmes.
