Worksh shop op 28./ ./29. 29.11. 1. BalticBoost Case Studies in MV CONCLUSION generally, loss from construction, dredging and dumping is very low on a broad scale

Worksh shop op 28./ ./29. 29.11. 1. BalticBoost Case Studies in MV CONCLUSION do not waste resources in trying to get better data for our assessment unit

Worksh shop op 28./ ./29. 29.11. 1. BalticBoost Case Studies in MV CONCLUSION sand extraction is an underestimated „big player“, more discussion is needed: How much area exactly? Is it really loss?

Worksh shop op 28./ ./29. 29.11. 1. BalticBoost Case Studies in MV CONCLUSION different picture on the small scale environmental agencies are probably doing a good job on the small scale
