Groundwater is the largest accessible source of freshwater and is of critical importance for humans and the environment. Irrigation is by far the largest user of groundwater worldwide and accounts for 17% of the global cropland area and 40% of the global food production. Currently groundwater is overused in various regions around the world and negative impacts are experienced. To reduce and prevent negative impacts of groundwater overuse, groundwater must be used more sustainably. At the same time, global food demands will rise and crop production has to increase to secure adequate food supply worldwide. A daunting global challenge lies ahead in how to use groundwater sustainable while at the same time sufficient crop production, to support regional and global food security, should be maintained.  In GROW we advance global groundwater and agricultural modelling to improve our understanding of sustainable groundwater availability and its role in supporting food production under current and future conditions.

Development of new version of the model VIC-WUR. Aiming for efficient coding and coupling of model components and modules, efficient writing of data, running in parallel etc. 

people involved: Karun Datadien, Sida Liu, Lisanne Nauta, Inge de Graaf.

current developments and plans:

• downscale to 5-arcminutes global resolution

• calibrate using MPR techniques

• rewrite the model with modular setup in Julia

Run time: 2023-2027

What is the impact of agricultural practices on groundwater quality? What is the contribution of groundwater to water quality in rivers, lakes and wetlands? How will groundwater quality change on future under climate change, increases in population and shifts in land use changes? 

This are the type of questions we try to answer in this project. In this project we will integrate estimates of groundwater quality to groundwater quantity at the global scale to asses current and future groundwater quality and related impacts.

• with this project we are involved in the ISIMIP water quality sector

COPERNICUS run time: 2025-2028

We are involved in the Copernicus seasonal forecast projects (funded by the European Commission, and implemented by ECMWF). In previous calls, we were involved in the European forecast. In the new call we will be involved in the European and Global forecasts (more details will follow).  

• some outputs of our contribution are discussed in the 'easy reads'
