Studenteropgave: Semesterprojekt


This project aims to examine the impact of the future climate change on nitrogen leaching in Denmark. The study is based on modelled climate data extracted from two catchment areas, Nissum Fjord and Karrebæk Fjord and the relation between data of run off and N-leaching. The catchments are chosen as they represent two extremities of Denmark. It then discusses existing methods used to assess climate change impact on nitrogen leaching, as well as the uncertainties associated with it. It concludes an increase in the total diffuse nitrogen leaching to marine waters by 15.7% and 22.4% respectively from Nissum - and Karrebæk Fjord catchment area. A comparison of the results of the calculation and results of the existing methods is made. The different results in increase total diffuse nitrogen leaching can be explained through the variables used and the underlying climate scenario. Moreover, it is concluded that in order to minimize the uncertainty in modelling the future nitrogen leaching as many factors as possible must be included.
