This new version of the model Swap was made possible with financial support from 2 projects :
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)
2. The SIGMA-project (Stimulating Innovation for Global Monitoring of Agriculture), financed by the ECís 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, 2016)
