The first primary objective of EUROHARP is to provide end-users (national and international European environmental policy-makers) with a thorough scientific 
evaluation of the nine contemporary quantification tools and their ability to estimate diffuse nutrient (N, P) losses to surface freshwater systems and coastal 
waters. Thereby facilitate the   
implementation of the EC Water Framework Directive.   
   
The second primary objective is to develop an electronic decision support system (tool-box) for the identification of benchmarking methodologies with 
respect to both costs and benefits, for the quantification of diffuse nutrient losses under different environmental conditions across Europe.    
   
EUROHARP will contribute substantially to improved comparability, transparency and reliability of the quantification of nutrient losses from diffuse 
sources, and thereby to improved efficiency of abatement strategies related to the implementation of e.g. the Nitrates Directive and the Water Framework 
Directive.
