Researchers have created an inexpensive hydrogel that can filter phosphorus from contaminated surface waters, drinking water supplies or wastewater streams to reduce phosphorus pollution and reuse the phosphorus for agricultural and industrial applications. In addition to efficiently capturing and releasing phosphorus, the hydrogels can be reused multiple times – making them cost-effective.

The Covid-19 pandemic, Russia’s war on Ukraine, geopolitical tensions, climate change and other events highlight our growing exposure to complex, interconnected, and intertwining risks. In view of this development, the focus of risk research has shifted towards the comprehensive analysis of interconnected and mutually interactive risk sources and crises. In a review article published in the  International Journal of Disaster Risk Science Huan Liu (Kyoto University) and Ortwin Renn (Research Institute for Sustainability, RIFS) offer an overview of the current state of research on polycrises and systemic risks.
