RESUMO
The EU Project AquaTerra generates knowledge about the river-soil-sediment-groundwater system and delivers scientific information of value for river basin management. In this article, the use and ignorance of scientific knowledge in decision making is explored by a theoretical review. We elaborate on the 'two-communities theory', which explains the problems of the policy-science interface by relating and comparing the different cultures, contexts, and languages of researchers and policy makers. Within AquaTerra, the EUPOL subproject examines the policy-science interface with the aim of achieving a good connection between the scientific output of the project and EU policies. We have found two major barriers, namely language and resources, as well as two types of relevant relationships: those between different research communities and those between researchers and policy makers.

Phosphorus (P) is the key limiting nutrient in most UK freshwater systems. With increased legislation controlling point source inputs, dissolved (DP) and particulate P (PP) derived from diffuse sources are making a more significant contribution to the total P loading of surface waters. Recent research has focused on pathways linking diffuse sources to the fluvial system and sub-surface field drains have been shown to transport both sediment and P rapidly to watercourses. Preliminary results are presented from an ongoing study using environmental tracers to identify the source of the drain sediment and its potential as a carrier of PP. These results suggest that the majority of sediment in drains is topsoil derived, but the significance of P loss via this pathway in a regional or UK context has yet to be evaluated. A protocol to study the potential problem at a regional/national scale is discussed and initial data presented.
