      abstract     = {In this paper, we outline several recent insights for the
                      priorities and challenges for future research for reducing
                      phosphorus (P) based water eutrophication in the
                      agricultural landscapes of Northwest Europe. We highlight
                      that new research efforts best be focused on headwater
                      catchments as they are a key influence on the initial
                      chemistry of the larger river catchments, and here many
                      management interventions are most effectively made. We
                      emphasize the lack of understanding on how climate change
                      will impact on P losses from agricultural landscapes.
                      Particularly, the capability to disentangle current and
                      future trends in P fluxes, due to climate change itself,
                      from climate driven changes in agricultural management
                      practices and P inputs. Knowing that, future climatic change
                      trajectories for Western Europe will accelerate the release
                      of the most bioavailable soil P. We stress the ambiguities
                      created by the large varieties of sources and
                      storage/transfer processes involved in P emissions in
                      landscapes and the need to develop specific data treatment
                      methods or tracers able to circumvent them, thereby helping
                      catchment managers to identify the ultimate P sources that
                      most contribute to diffuse P emissions. We point out that
                      soil and aqueous P exist not only in various chemical forms,
                      but also in range of less considered physical forms e.g.
                      dissolved, nanoparticulate, colloidal and other
                      particulates, all affected differently by climate as well as
                      other environmental factors, and require bespoke mitigation
                      measures. We support increased high resolution monitoring of
                      headwater catchments, to help verify not only the
                      effectiveness of catchments mitigation strategies, but add
                      research data to develop new water quality models (e.g.
                      those include Fe-P interactions) and can deal with climate
                      and land use change effects within an uncertainty framework.
                      We finally conclude that there is a crucial need for more
                      integrative research efforts to deal with our incomplete
                      understanding of the mechanisms and processes associated
                      with the identification of critical source areas, P
                      mobilization, delivery and biogeochemical processing, as
                      otherwise even high-intensity and high-resolution research
                      efforts will only reveal an incomplete picture of the full
                      global impact of the terrestrial derived P on downstream
                      aquatic and marine ecosystems.},
