We show that biochar can activate peroxydisulfate to eliminate widespread persistent and mobile organic contaminants from urban stormwater. Our laboratory-based investigation provides the basis for future studies towards the practical implementation of biochar and peroxydisulfate for stormwater treatment.

The authors analysed 22 case studies of biodiversity-enhancing societal processes and projects in Germany to identify barriers and success factors, as well as features that support transformative change towards sustainability and the mainstreaming of biodiversity. They identified 16 features that support transformative change for biodiversity, many relevant beyond Germany. 

The authors simulated seasonal and long-term changes in the spatio-temporal patterns of water storage dynamics and groundwater–surface water interactions in lowland tributary of the Spree catchment. After several major droughts, groundwater stores are depleted and stream flows intermittent. This shows the importance of integrated land and water management in NE Germany.
