Marine Ecosystem Dynamics and Indicators for North Africa
MEDINA Overall objectives:
-To contribute to the assessment of coastal ecosystem status in North African countries;
-To enhance the monitoring capacity in the region.
-To feedback MEDINA ’s scientific contribution within the EU regulatory framework.
-To ensure the optimal exploitation of the GEOSS
Common Infrastructure (GCI) in supporting on going monitoring&assessment
Project supported by the EC under FP7-ENV-2011-1 n ° 282977

Marine Ecosystem Dynamics and Indicators for North Africa
MEDINA ’s key features:
-Driver-Pressure-State-Impact-Response conceptual framework for on-going monitoring and assessment.
-Use of models (biogeochemical, Species Distribution,
Food Web etc ….) for relating Drivers/Pressures to
State/Impacts.
-Fusion of remotely-sensed and in-situ observation, through modelling, for monitoring optimization.

MeI: stage of development
-The basic structure of the reference catalogue for the Medina e-Infrastructure (MeI) has been defined;
-The MeI is operational and is being populated ;
- Pilot cases: an Architecture Implementation Pilot has been developed (Species Distribution Model for Posidonia oceanica): see video.

The Medina e ‐ Infrastructure viewer is designed to improve visualisation and analysis of spatial data through tools such as: zoom in and out, pre ‐ defined selection of areas, a tool for adjust layers transparency.

The GEOSS searching tool allows the user to look for specific environmental topics among the GEOSS Data
Catalogue and the Medina catalogue, thereby assuring the exploitation of the GEOSS GCI resources.

The MeI data catalogue groups the indicators within three categories: Ecological Objectives and DPSIR, Modelling
Outputs and Earth Observations

MEDINA contribution to the implementation of UNEP-MAP EcAp
Project supported by the EC under FP7-ENV-2011-1 n ° 282977

Marine Ecosystem Dynamics and Indicators for North Africa
Progress towards ECAP entails important challenges for all Mediterranean countries: The approach is complex and a huge monitoring effort is required to assess the ecosystem status in relation to GES for all the 11 EcOs.
MEDINA will focus on 3 EcOs that are relevant for the area and can be addressed (fully or partially) by remotely sensed EO and modelling :
EcO1 Biodiversity
EcO5 Eutrophication
EcO9 Contaminant

Species Distribution Model (or Habitat
Suitability Model, HSM) are often used to integrate or extrapolate sparse occurrence data
(Elith & Leathwick, 2009).
The application of the Posidonia DM provides an estimate of the potential extension of the
Posidonia habitat, thus allowing the estimation of one key UNEP-MAP operational objective and related indicators, namely, OO 1.4 (Key coastal and marine habitats are not being lost)

Next steps
- The MeI will be populated with the results of the regional ecosystem assessement and those concerning five test areas (Pilot Cases)
-The MeI will be presented to monitoring agencies and stakeholders at four National workshops, to be held in Algeria, Egypt,
Morocco and Tunisia in May-June 2014.
Meetings will be focused on EcAp implementation.
