For many years now, nitrate concentrations have exceeded the trigger value of 50 milligrams per liter at nearly one-fifth of the groundwater sampling sites in Germany. Apart from impairing the ecosystem by, for example, causing eutrophication of water bodies, nitrate-polluted drinking water also...

The effects of the climate crisis are worsening water shortages, not only in the Global South but also in Europe, for example in the Berlin-Brandenburg region. Due to inadequate pricing of surface and groundwater abstraction and a lack of regulatory instruments, water overuse is occurring in...
