Acknowledgment

This new version of the model SWAP was made possible with financial support from 2 projects:

1. The Watervision project, a Dutch project with a large group of financers: STOWA (Applied Research of the Water Boards), Ministry of Infrastructure and Environment, ACSG (Advisory Commission for Damage related to Groundwater), provinces Utrecht and Zuid-Holland, ZON (Zoetwatervoorziening Oost- Nederland), Water companies Vitens and Brabant Water, VEWIN, LTO and the Ministry of Economic Affairs (project KB-14-001-046). The Waterwise project supported extensive testing and documenting of the soil hydrology and crop growth relations with a focus on The Netherlands (Kroes et al., 2017; see References)
2. The SIGMA-project (EU SIGMA project Stimulating Innovation for Global Monitoring of Agriculture), financed by the EU Research Framework programme (FP7) under grant agreement No 603719. Within the SIGMA project the C and N modules were developed, tested and described, with an international focus (Groenendijk et al., 2017; see References)
