Workshop on detection of human impact in the Göta River estuary
Hotell Arken, Göteborg, Sweden
This workshop will follow directly after a NMA-funded PhD course called "Marine Ecotoxicology – from Gene to Ocean"
August 26-29, 2007
Organised by Göran Dave, Plant and Environmental Sceiences, Göteborg University.
Participation: Participation by invitation.
This workshop has now taken place Read the workshop report.
to be held at Kristineberg Research Station August 19-25 2007. Workshop participants will be selected among recognized international experts and local experts from academia and environmental authorities. Altogether 15 experts and 5 PhD students will be invited to participate.
The Göta River divides about 30 km before it reaches the Kattegat. The southern branch, also called Göta älv passes a major city, Göteborg. The northern branch, called Nordre älv, has almost no human impact. This is a unique example of a locally impacted river and estuary with it own reference nearby.
The aim of the workshop is to make a state of the art report on the present knowledge on environmental impact assessment in large systems, and to define import gaps in knowledge on the separation of human impact from point sources in Göteborg and diffuse sources from the entire watershed. The report is also intended to be the starting point for a research project proposal to be part of the recently established research platform “Ecotoxicology - From Gene to Ocean” at Göteborg University in co-operation with international experts.
