1 Ecological-social-economic conditions Environmental measures
Gerald Oder (Szczecin) Lagoon Conceptual model Gerald: Ecological-social-economic conditions Landscape conditions Spatial planning Legal frameworks Local acceptance Water quality targets Effects on birds & fish Fisheries Tourism Bathing water quality Scenarios Number, location, size, depth, intensity, structure & combination of environmental measures Conceptual model Nutrients (N,P) Mussels Mussel farming Zooplankton Phytoplankton Cost-revenue model Nutrient loads Detritus N-Fixation Mussel harvest Environmental measures Mussel farming Macrophyte stocks Groin systems Oxygen Denitrification Nutrient removal Sediment Sediment resuspension Water transparency Cost-effectiveness Cost-benefit models Weather Currents Salinity Temperature Macrophytes/groins Society & Governance 3D Flow- & Ecosystem model Assessment Ecosystem Service evaluation & sustainability indicator analysis

2 Cost-revenue model - mussel farm
Cost-benefit (CBA) model Cost-revenue model - mussel farm Oder (Szczecin) Lagoon Economic conceptual model Macrophyte stocks Mussel farm Cost module Transport/distance Water depth Hydrodynamic Structure Locations Species Establishment & maintenance costs Effects on birds & fish Fisheries Nature protection Effects on birds Fish & fisheries Tourism Bathing water quality Nature protection Capital costs Maintenance Investment Harvesting/labour Laboratory analysis Gerald: General ESE scenarios Variables that link ecology & economy Specific economic scenarios Yield module Nutrition Water depth Hydrodynamic Groin sytems Mussel harvest Substrate Farm structure Growing period Care & handling N & P removal Water transparency ESE conceptual model Sales module Market capacity Transport costs Treatment/storage Fresh mussels Cost-effectiveness (CEA) model (of measures to reach pre-defined targets) Poultry & pig farm Fish aquaculture Pet food & Zoos Mussel farms Macrophyte stocks Groin sytems Combined measures River basin measures Mussel meal Compensation, subsidies & funding mechanisms Nutrition Fertilizer Mussel shells

3 Oder (Szczecin) Lagoon Social conceptual model
Mussel harvest Cost-benefit (CBA) model Oder (Szczecin) Lagoon Social conceptual model N & P removal Macrophyte stocks Mussel farm Water transparency Johanna: Groin sytems Variables that link ecology & economy Regional identification/Quality of life/Attractivity of the region Cross-border cooperation Fisheries Tourism Bathing water quality Regional/Local products and services Diversification of tourism/leisure opportunities Extension of tourism season Regional development Other uses Education & awareness Acceptability Spatial & use conflicts General ESE scenarios Water quality (macrophytes, tranparency) Ecological impacts (composition of fish species) Regional/Local products and services Diversification of business (jobs, income, second mainstay for fishermen) ESE conceptual model Regional development
