Objective: understanding interactions between different maritime activities and between maritime activities and the marine enviromnent.

This sub-component will develop and test tools designed in order to support MSP processes, providing assessments of main conflicts to be addressed, improving stakeholders and decision makers understanding of the spatial distribution of the main issues.

Tools and methods to support the MSP process, will in particular take into account the need to cormect Maritime Spatial Plamring with the assessment of cumulative impacts on areas. In line with C1.l. and Cl.3.2, geo-referencing and functional tools to support the definition, the analysis of condition and the size of marine areas will be applied.

C Interaction between uses and between uses and environment, including cumulative impacts

North Atlantic region show specificities regarding at stake activities and enviromnental features: Important fishing and aquaculture sector, aggregate extraction, Zostera sea grasses meadows, Maërl beds, protected species (to be precised with regard to the initial assessment). A better understanding of what interaction could occur between these prior features is crucial to support the
planning process.

A review of knowledge about interactions between maritime sectors and about effect of activities on marine environment will be performed though a desk analysis gathering local or national studies and summarizing them through operational tool such as interaction matrices. This action would especially benefit from MFSD and OSPAR work regarding effects of human activities on the environment.

Then, an operational method will be designed to effectively assess and localize interactions and overlapping issues within the area of interest. This to support the planning steps throughout the overall process. This action will propose a step by step method aiming at identifying and commrmicating on interaction issues (between activities and between activities and environment). Will be described for each step (locating activities and environment features, locating maritime sectors and environment area of interest, locating major overlapping area and issues associated…) technical aspects (data required, data processing…) and the way that these steps can be integrated within the planning process (conrrnunication, dialogue with stakeholders and decision makers). Coordination will be done with methods developed within others projects supported by the commission (SIMCelt, Mediterranean and future other calls).

Then a practical test of interaction assessment will be performed on a limited area to be defined (see below C1.3.6)
