Priority list (with regard to UNCLOS) MSP at an early stages: (between 2001‐2006) High  Safety and efficiency of shipping   Defining the actual state of National and international uses contracts [e.g. pipelines, cables] Shipping & Pipelines, Cables, Mariculture, Military Features Sediment, Platforms  Protection of the marine  Ascertain priorities of environment  National/Alliance defence different uses Others   Set priorities regarding Resources national and international  Scientific research Nature Conservation Offshore Wind Farms  Wind farming “dependencies”.© B.

Multi-use ideas to maximize the 1. Ecologybenefit of an offshore area: - Creating MPA‘s (nursery, sustainable fisheries…) - Set-up artificial reefs 2. Tourism 3. Additional energy resources 4. Offshore Aquaculture 5. Bio-Remediation / Bio-Extraction 6. Use of fouling organismsImage taken from Barry Costa‐Pierce© B. H. Buck 2012 - MSP-Symposium 2012

Key Issues: 1. Multi-use concepts ease MSP 2. Multi-use will have a better acceptance for both stakeholders and would save costs. 3. Multi-Use concepts will have economic benefits • Quick procedure • Combined EIA • Shared vessels/personal Prof. Dr. Bela H. Buck • training • Additional biomass Bela.H.Buck@awi.de • etc.© B. H.
