Water shortage in Germany - New ideas for long-term security

People and countries worldwide are facing more droughts, more heat and growing water shortages. Even in Germany a sufficient supply of water cannot be taken for granted everywhere. The hope now is to secure that supply with new - and old - ideas.

Some regions have had an acutely dry last few years, and groundwater levels have plummeted. The causes are not just more drought periods but also soil sealing - and higher pollutant levels in the water have also become a problem.
The search for solutions has many facets. Günther Westenhoff has spent years using his divining rod to track down water sources for drilling companies. Increasing aridity means they have to bore deeper and deeper. While he cannot explain how his divining rod works, he shows us that it produces results.
