Drought in Switzerland: 80% of groundwater at risk (cross-border guide)

Context

In short

• Drought threatens Switzerland's water supply, with 80% of drinking water coming from underground sources.
• Experts propose monitoring, renaturalization of watercourses and territorial planning.
• Collaboration between the Confederation, Cantons and user sectors is essential to manage the crisis.

Key facts

• What: Drought in Switzerland, risk for groundwater
• When: Not yet specified
• Where: Switzerland, with focus on the Jura and the Alps
• Who: Swiss Academy of Natural Sciences (SCNAT)
• Amount: 150 cubic kilometers of groundwater in Switzerland

Drought is becoming a recurring challenge in Switzerland, putting at risk 80% of the country's drinking water, which comes from underground sources. The Swiss Academy of Natural Sciences (SCNAT) is sounding the alarm: groundwater levels are falling and springs are drying up, especially in the Jura and the Alps. This situation can cause water shortages for families, agriculture and industry, as well as threatening water quality with higher concentrations of pollutants.

Measures proposed by experts

Experts propose various measures to address the crisis: systematic monitoring of water withdrawals, replenishment of aquifers through the removal of soil sealing and renaturalization of waterways. These solutions should be integrated into spatial planning.

SCNAT highlights the importance of close collaboration between the Confederation, cantons, municipalities, distribution companies, the agricultural sector and other user groups for effective responses. The impact of drought varies from region to region: the large aquifers of the Plateau can act as a buffer, while in the Jura and the Alps the sources can run out quickly.

Impact of drought on the economy and society

Drought in Switzerland is not only an environmental problem, but also has significant economic and social implications. Agriculture, which is highly dependent on water resources, could suffer significant losses, impacting food production and prices of agricultural products.

Sectors affected

• Agriculture: Reduction of crops and increase in irrigation costs.
• Industry: Increase in energy and production costs due to water scarcity.
• Families: Possible rationing and increase in water tariffs.

Water quality is another critical aspect. As groundwater levels decline, pollutants can concentrate, making water undrinkable without additional treatment. This could increase costs for distribution companies and, consequently, household bills.

Long-term solutions

Renaturalizing waterways and removing soil sealing are long-term solutions that can help restore ecosystems and ensure a sustainable water supply. However, these measures require significant investments and careful planning.

Collaboration between various levels of government and use sectors is crucial. The Confederation, cantons and municipalities must work together to implement effective policies and ensure that water resources are managed sustainably. To better understand the economic impact of the drought, it is useful to analyze economic data and price trends, for example by consulting the costo della vita in Svizzera.

Key points

Concrete actions to address drought

To address drought effectively, concrete measures need to be taken at individual, municipal and national levels. Here are some steps that can be taken:

At the individual level

• Water saving: Reduce water consumption in the home and garden.
• Monitoring: Report any waste or losses to the competent authorities.
• Information: Keep up to date on the measures adopted at local and national level.

At the municipal level

• Planning: Integrate water management measures into territorial planning.
• Investments: Financing renaturalization projects and removal of soil sealing.
• Collaboration: Working with citizens and businesses to promote sustainable practices.

Nationwide

• Legislation: Implement laws and regulations for sustainable water management.
• Funding: Allocate funds for research and innovation projects in the water sector.
• Education: Promote awareness campaigns on the importance of saving water.

To best manage water resources, it is essential to adopt a holistic approach that involves all levels of society. Switzerland has the opportunity to become a model of sustainable water management, ensuring a secure future for generations to come. To learn more about the economic implications of the drought, it is useful to consult the costo della vita in Svizzera and the price trends of agricultural and industrial products.
