2
PEGASO project – FP7 ENV.2009-1
PEGASO : European project aiming at building on existing capacities to develop common novel approaches and practices for sustainable development and environmental protection of coastal zones in the Mediterranean and Black Seas
3
10 ICZM Collaborative Application SitES (CASES)
CASE Bouches du Rhône
PEGASO CASES
4
CASE Bouches du Rhône
Rhone river
200 m
Berre lagoon(excluded)FOS industry
harbourcomplex
Camargue delta
Côte Bleue
Marseille area
CASE extent 120 km
Ligurian current
4 very distinct entities
5
ICZM CASE Bouches du RhôneMain drivers (EEA DPSIR framework)
Conserve (semi-)natural ecosystems, marine habitats, wetlands, water quality. Considered as important for population well being
Development of tourism and recreational activities
Preserve traditional professional fishing activities
Urban, peri urban and industrial development
1962 -> 1999 BdR population +47% (2 times France pop. increase rate)
Marseille urban community management plan (SCOT): + 80000 to 100000 inhabitants (+5%) expected in 2030
Harbor extension
6
Several local level management plans in the area
Côte Bleue
Marseille city& harbour
Camargue Natural Regional Park
7
Focus on the interactions between the 4 distinct entities
Consider relationship between coastal environment quality and socio-economic activities
1st step : territorial diagnosis (requires discussions with stake-holders)
Question:
Assess the impacts of current trends and management choices on the marine and coastal uses
Method :
Consider a baseline scenario and several variants of this trend scenario
Distinguish trends independent from local decisions (national policies, industrial strategies...) and trends resulting from local decisions
Characterize the elements of the baseline scenario by quantitative indicators
CASE Bouches du RhônePEGASO project approach
8
CASE Bouches du RhôneIndicators
Sea side limits based on WFD water masses
Land side, territorial unit limits base on administrative communes
• Select a – reduced - set of indicators applicable at local scale regarding :
- ecosystem status - pressures - economic data
• Historical analysis
• Consider :
- Agriculture - Urban areas - Industry - Natural protected
areas - Harbours - Tourism/recreative
activities - Aquaculture and
fishing
9
Land use indicators
Corine land cover base (data since 1975 in the coastal strip)
Carte : Observatoire du littoral
10
Indicators based on INSEE statistics
Source : Observatoire du Littoral
11
Marine environment quality
Camargue FOS
Mercury in sediment, 1995-2005
Bathing water quality : 22 monitoring stations in Bouches du Rhône
12
Bouches du Rhone/Marseille – Example of data set : Marine benthic habitats
Pas de séries historiques
13
Exemples of indicators
Number of marinas
Number of moorings
Number of diving clubs
Hotel capacities
Tourism and recreational activities
14
Availability of harmonized socio-economic indicators at local scale
Consideration of transport issues
Key points at this stage
Trafic routier entre Aix et Marseille+84% en 16 ans
15
Use conflicts -> field approach
Key points at this stage
