Development of a Methodology for the Assessment of Cumulative Effects of Marine Activities Using Liverpool Bay as a Case Study (2002)
Former Countryside Council for Wales (CCW) and now Natural Resources Wales (NRW), encourages good practice in undertaking Environmental Impact Assessments (EIAs) for developments and activities, including those located in Welsh Territorial waters (up to 12 nm offshore). Experience has shown that EIAs carried out in the marine environment often address impacts of the development in isolation from other similar developments or other developments having similar impacts. A review of environmental statements produced for offshore oil and gas developments found that none addressed cumulative impacts over the projects lifetime or with regards to adjacent existing or proposed developments. It can therefore be said that cumulative impacts from marine activities have seldom been adequately addressed in EIAs for offshore projects.
The purpose of this data capture is to:
- Review current understandings of potential cumulative effects from offshore industries and develop a proposed methodology for cumulative effects assessment of offshore industries from a nature conservation and landscape / seascape perspective;
- Produce a GIS database and analysis tool for offshore Cumulative Effects Assessment (CEA);
- Identify current and predict likely future cumulative effects from offshore industries in Liverpool Bay on habitats and species of importance; and
- Identify data gaps, and recommend further data and research requirements for undertaking CEA for offshore activities.
