From treatment plants to hot showers, emissions from water use in the U.S. are equal to 50 million cars driving around for a year. In The Washington Post, staff writer Tik Root consults different experts to learn about ways to reduce our water consumption. He also speaks with Leiden environmental scientist…

Netherlands and China can learn from each other to handle household and livestock wastewater more sensibly. In the FOREWARD project, scientists from Leiden, Wageningen, and China are working together with local partners on feasible solutions that advance the environment, health, and economy.

In supermarkets, consumers are drowning in a sea of sustainability labels. Confusing for them, but also farmers can't see the forest for the trees. Obtaining these labels demands an enormous amount of time and effort. Berent Baris is investigating ways to simplify this process, benefiting both farmers…

In 2011, the Udhruh Archaeological Project was launched, bringing together teams of Jordanian and Dutch archaeologists to investigate the region and reconstruct ancient water harvesting techniques in the extremely arid landscape of Udhruh. Access to fresh water remains one of the most pressing global…

The coal-power energy sector is using enormous amounts of fresh water which is projected to negatively affect lives and the ecological balance of the surrounding region. This is the conclusion of the new report The Unquenchable Thirst of Energy Production, published by Greenpeace Bulgaria and Leiden…

About 15 km to the south of the ancient city of Petra, archaeologists from the University of Leiden have discovered an impressive network of ancient water conservation measures and irrigated field systems.

How can we make agricultural production systems more sustainable as the worldwide demand for healthy, safe food continues to grow? How can we develop healthy new food crops that have higher yields while requiring fewer harmful chemicals?

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…
