Aim

The COEXIST – sea uses conflict analysis tool was developed during ADRIPLAN project. The tool is based on a methodology developed for the FP7 COEXIST Project and has the aim to (1) support MSP process through reallocation of maritime uses, (2) creation of collaborative conflict scores analysis; (3) iteration of the analysis over different time periods trough integration of new conflict scores and geospatial datasets on sea uses, (4) sea use scenario analysis and (5) overlay analysis.

The stepwise methodology implemented in the COEXIST – sea uses conflict analysis can be described as follows (see also Figure 1):

Step 1:

Identification and collection of relevant sea use datasets.

Step 2:

Normalization of use layers on a 1 km2 grid size using the European Environmental Agency Reference Grid (EEA, 2012).

Step 3:

Expert based definition of spatial and temporal attributes (vertical domain; activity spatial domain; activity temporal domain; mobility) and calculation of “conflict score” for sea use pairs located in the same cell.

Step 4:

Geospatial visualization of spatial conflict scores, representing the potential spatial and temporal conflict between sea uses.

Outputs

The main outputs of the tool are the following:

• Quantification and visualization of overlapping sea uses by considering current and future sea use scenarios.
• Generation of statistical outputs (plots and tables) to inform on sea use contribution to conflict scores.
• Analysis of data gaps in terms of data availability, quality and geospatial extent based on data availability maps and statistical outputs.
