Description:
Due to the climate change the emission of nutrients from soils may change, Also the retention in the surface water will be affected. This possibly will hamper the realization of the ecological WFD-goals. In this study these effects will be estimated and policy implications will be described.
Research objectives:
First the climate change affected factors that influence the nutrient cycle in soils will be identified. Then the final work plan will be written. Existing data and methods will be used as much as possible. Important decision is how the effects of climate change have to be estimated: reference events, climate periods (30 year periods), stochastic events or other methods. Probably the emissions from soil, the emissions from urban area s and the retention in surface water need other methods because of the specific scales in time and space. Then special attention is required to integrate the results.
Dependent on the needed methods existing data, models an instruments have to be selected, adapted and coupled. With the operational instruments the emission and retention in both the current situation and a Dutch climate scenario will be calculated. Results will be checked, reliability will be checked, and effects will be analyzed to estimate effects of climate change on the emission of nutrients from soils and from urban area s and to estimate effects of climate change on the retention of nutrients in the surface water. Effects will be translated to conclusions an policy advices.
Results and products:
The results and conclusions in the report can be to improve national policy and to adapt the regional implementation of the WFD. |
