Spatial conflicts among human activities as well as with conservation priority areas in Western Greek waters


This report is developed within the framework of the PORTODIMARE project that aims to create a common platform (Geoportal) for data and information related to coastal and marine areas of the Adriatic-Ionian Region, by integrating existing databases, portals and tools developed by previous EU-funded projects (e.g., SHAPE, ADRIPLAN), local and national administrations and other initiatives.

Questions this practice may help answer:

  • What are the cumulative effects of aquaculture, tourism and fisheries on key ecosystem components in the Western part of the Greek Sea?
  • Where are the hotspots of conflicts located in the Western part of the Greek Sea?

Implementation Context:

This report is the result of the testing activity T2.4 of the PORTODIMARE project which aims to assess and map cumulative effects of aquaculture, tourism, and fisheries, with a special focus on small scale fisheries (T1.11), on key ecosystem components, and to identify and map the spatial conflicts between human uses in the case study area.

Aspects / Objectives:

The main objective of this report is to compile data and map the conservation priority ecosystem components (Posidonia oceanica, Monachus monachus and Delphinus delphis), as well as the maritime activities, and then apply the CEA module to identify hotspots of conflict in the Western part of the Greek Seas.


The method used is explained in part 3 of the report, and as follows:

"The workflow adopted for the elaboration of the Greek Case Study is structured in three operational steps.

Step 1: Testing the Geoportal of the Adriatic-Ionian Region (GAIR) to create a knowledge framework: it includes updating necessary data and metadata and processing thematic maps required for MSP analysis within PORTODIMARE.

Step 2: Testing the Tools for MSP, considering the current condition in the case study area. In particular, the following analysis was performed: small-scale fisheries (SSF) and medium-scale fisheries (MSF) modules to estimate the fishing effort, analysis of cumulative effects assessment using CEA Module.

Step 3: Preliminary effort to integrate results from different modules".

Main Outputs / Results:

This report is dedicated to testing the module of the Cumulative Effects Assessment (CEA) in combination with the module on the SSF footprint in the Greek case study area, while special effort has been made to integrate outcomes with those from the module of the Allocated Zones for Aquaculture (AZA).

The Geoportal of the Adriatic-Ionian Region (GAIR) constitutes an ‘all-in-one toolbox’, that may provide significant feedback to be used by planners in MSP implementation.


Although this report is a study which focuses on the Western part of the Greek Sea and cannot be transferred to other regions, the method used can be taken as an example for different regions.
