Discussion: Climate Change and Water Policy (2004) • What do we know about climate change scenarios for Europe and its various regions? • How is this likely to affect water resources, river flow and river basin management? • What are the impacts on biogeochemical cycles and contaminant cycling? • What are the impacts to ecological functioning, biodiversity, fish dynamics and stocks. Conference JRC & Estonia
