Journal article (peer-reviewed)abstract
- Agricultural management practices are among the major drivers of agricultural nitrogen (N) loss. Legislation and management incentives for measures to mitigate N loss should eventually be carried out at the individual farm level. Consequently, an appropriate scale to simulate N loss from a scientific perspective should be at the farm scale. A data set of more than 4000 agricultural fields with combinations of climate, soils and agricultural management which overall describes the variations found in the Baltic Sea drainage basin was constructed. The soil-vegetation-atmosphere model Daisy (Hansen et al. 2012) was used to simulate N loss from the root zone of all agricultural fields in the data set. From the data set of Daisy simulations, we identified the most important drivers for N loss by multiple regression statistics and developed a statistical N loss model. By applying this model to a basin-wide data set on climate, soils and agricultural management at a 10 x 10 km scale, we were able to calculate root-zone N losses from the entire Baltic Sea drainage basin and identify N loss hot spots in a consistent way and at a level of detail not hitherto seen for this area. Further, the root-zone N loss model was coupled to estimates of nitrogen retention in catchments separated into retention in groundwater and retention in surface waters allowing calculation of the coastal N loading.

Introduction, the Science-Policy-Stakeholder Interface
- 2010
-
In: Science, Policy and Stakeholders in Water Management. - London : Earthscan. - 9781844079193 ; , s. 1-13
-
Book chapter (other academic/artistic)abstract
- One of the major problems facing practitioners and scientists working with water management is how to integrate knowledge and experiences from scientific, policy and stakeholder perspectives. In this book this science-policy-stakeholder interface (SPSI) is examined both analytically and through the description of practical experiences from river basins in Europe, India and South-East Asia. These include the Tungabhadra (India), Sesan (Vietnam/Cambodia), Tagus (Spain/Portugal) and Glomma (Norway), which particularly highlight issues associated with pollution, severely altered river flows and transboundary conflicts.Following two chapters which lay the framework for the book the authors describe how SPSI was managed in the case study basins and how stakeholder participation and scenarios were used to integrate different perspectives, and to facilitate the communication of different forms of knowledge. Four important aspects of water management and SPSI are then discussed; these are water pollution, land and water interaction, environmental flow and transboundary water regimes. Short descriptions of the case study rivers are provided together with analyses of how SPSI was managed in water management in these basins and policy recommendations for the basins.The book concludes by providing a series of recommendations for improving the science-policy-stakeholder interface in water management. It represents a major step forward in our understanding of how to implement integrated water resources management.

STRIVER in the context of IWRM
- 2010
-
In: Integrating Water Resources Management. - London : IWA. - 9781843393252
-
Book chapter (other academic/artistic)abstract
- The concept of integrated water resources management (IWRM) has been around for some60 years. It was rediscovered by some in the 1990s. While at a first glance, the concept of IWRM looksattractive, a deeper analysis brings out many problems, both in concept and implementation, especiallyfor meso- to macro-scale projects. The definition of IWRM continues to be amorphous, and there is noagreement on fundamental issues like what aspects should be integrated, how, by whom, or even if suchintegration in a wider sense is possible. The reasons for the current popularity of the concept areanalyzed, and it is argued that in the real world, the concept will be exceedingly difficult to be madeoperational.
