Analysis of agricultural and environmental measures in the context of agricultural water conservation and of the EU Water Framework Directive
Project
Project code: TI-LR-02-PID984
Contract period: 01.10.2005
- 31.12.2014
Purpose of research: Inventory & Assessment
Diffuse nutrient pollution from agriculture is a major reason that the objectives of the EU Water Framework Directive (WFD) for the water quality in many regions of Germany are not expected to be achieved. In various 'AGRUM subprojects', we examine measures of agricultural water conservation using an agro-economic and hydrological model network. The main goal is to evaluate how these measures effect on the water quality and what costs are to be expected. The various 'AGRUM subprojects' use the same model approaches but differ in terms of study region, runtime and client.
With the coupling of the models RAUMIS, GROWA, DENUZ / WEKU and MONERIS, we managed to create a model system that is suitable to illustrate the nutrient status of an entire river basin, both realistic and differentiated - in terms of large areas as well as by pathways and necessary actions and to analyze options for appropriate action. We have also made sure that the models can be transferred with relative ease to other river basins (with available data bases). In addition, the composite model is suitable to analytically accompany the action programs of the catchment areas. Over the last 15 years we have seen that nutrient balance surpluses are reduced. According to the model calculations, this will continue until 2015. Caused by the residence times of nutrients in the soil and groundwater system, the time needed for improved conditions can differ between the regions. However, in a projection until 2015 under status quo conditions (baseline), if one takes into account delayed effects, neither the goals for groundwater nor for surface water could be achieved for the two studied nutrients, nitrogen and phosphorus.
