'Rhine 2040' programme adopted

13.02.2020 - The 16th Conference of Rhine Ministers was held in Amsterdam on 13 February 2020. It successfully adopted the 'Rhine 2040' programme, with its new and ambitious targets for biodiversity (the return of migratory fish), water quality (a reduction in micropollutants), climate change, flood defences and measures to deal with low water levels.

 
 
 

Plant protection products

High concentrations of plant protection

The "NAWA SPEZ 2017" study examined the impact of plant protection products in five small water courses. The study revealed that creeks are affected commonly in regions with intensive agriculture.

Water flow and flow regime

Water supply depends on natural factors and is influenced by hydropower production and climate change. The FOEN is monitoring the water flow and flow regime of Swiss bodies of water. 

Monitoring data and statistics

Current monitoring data on bodies of water, the possibility of obtaining data, information about extreme value statistics and data on the water withdrawn and returned

State of waterbodies

Despite the generally good quality of its water, residues from fertilizer and plant protection products, chemical residues from wastewater, as well as man-made structures and artificial obstacles damage surface and underground waters.

Ground water

Good quality groundwater is available in sufficient quantities almost everywhere in Switzerland. Traces of artificial, rather persistent substances are found mainly below cropland and in settlement areas.
