6. ACKNOWLEDGEMENTS 
The case studies of the Württembergisches Allgäu and of the 
“Kraichgau” were investigated within the Graduiertenkolleg 
GRK 259 “Mitigation Strategies for the Emission of 
Greenhouse Gases and Environmentally Toxic Agents from 
Agriculture and Land Use“. The case study of the Rur- 
Watershed was investigated within the CRC TR 32 “Patterns in 
Soil-Vegetation-Atmosphere-Systems. Monitoring, Modelling 
and Data Assimilation”. All three projects were/are funded by 
the German Research Foundation (DFG). We thank the German 
Aerospace Center (DLR) for the provision of data from the 
RapidEye Science Archive and Geobasis NRW for the 
provision of the ATKIS-Basis-DLM. Additionally, we thank the 
Landwirtschaftskammer NRW for the supply of the ‘Feldblock’ 
data.
