The Blue Economy development presupposes the rational and sustainable exploitation of marine resources and maritime space. The starting point is of course the existing situation: which activity exploits what resources, where and when?
However, answers are still very incomplete and rather inadequate: not only is little information available, but much of this information is provided by the users themselves, with the level of detail that suits them. It is often quite limited.
Thus, even if public access to AIS data is wider, these data are provided voluntarily (AIS can be stopped at any time, or false positions can be injected in, …) and often incomplete: at best, they indicate the presence of a vessel and its type, but its complete description of the activity is usually not provided (the vessel is simply in transit, fishing, if so with what gear?).
SML has developed and continues to develop with her partners within the framework of its “SESAM” project, monitoring information analysis services that enable detailed mapping of activities (nature, spatio-temporal density, etc.). The system can use virtually any data (active or passive radar, AIS, GSM trajectography, etc.).
The analysis of maritime activities has many applications: regulatory compliance monitoring, management of maritime and security risks, defence and safety, cumulative impact assessment, etc.). SML is focusing efforts on using this information to support integrated approaches, including MSP.
In collaboration with the Université de Bretagne Occidentale (UBO/IUEM), and within the framework of the CIFRE scheme, SML is conducting a doctoral thesis (2017-2019). Its aim is to study and evaluate how the mapping of maritime activities, based on the analysis of surveillance information, can contribute to the implementation of Maritime Spatial Planning and its related policies.
This research aims to contribute to the improvement of spatialised knowledge of maritime activities and methodological advances useful for decision-making at sea.
Two main work phases have been identified at this stage:
- A global inventory of the mobilization of the representation of maritime activities in the framework of the Maritime Spatial Planning, in order to identify the potential contributions of the use of surveillance data in this context, and
- The analysis of the positions of the main stakeholders, both promoters of the approach (institutions, project leaders) and sea users regarding a mapping of activities based on observed information – and no longer actors’ declarations
