Worrying insights into the chemicals in plastics

ETH Zurich researchers examined chemicals in plastics worldwide. They found an unexpectedly high number of substances of potential concern intentionally used in everyday plastic products. A lack of transparency limits management of these chemicals.

A check-up for the ground

Intense agricultural use is causing soil degradation in many areas. Now researchers at ETH Zurich have developed a rapid test for measuring soil quality on site. This should allow farmers to monitor the health of their land themselves in the future.

Juggling with constant change

A cultural landscape reflects the combined activity of nature and humans. Where has the equilibrium of this union been lost? And how can we restore the balance?

Updating the self-sufficiency ratio

The level of self-sufficiency indicates the extent to which agricultural performance ensures food security. But it’s not geared to the challenges that confront agriculture today, says Roman Hüppi.

“We have to ask some uncomfortable questions”

All human activities affect the landscape and ecology, even if we stop using nuclear energy and rely on renewable energy. Astrid Björnsen led the joint Energy Change Impact research programme of WSL and Eawag. It provides accurate data on the potential and availability of renewable energy in the country.

Skewed perceptions in climate policy

The benefits of strict climate policies are often underestimated in public debate, while the costs are generally overestimated, says Lucas Bretschger. Climate protection does not have a negative impact on economic development.
