In order to engage with members, offer new learning experiences and maintain online the much loved “LUCI Family” atmosphere of our in person events, the LUCI Coffee Bre@ks were created. These short 30-minute regular online rendezvous sessions are an opportunity for members to stay in touch and hear from experts on a variety of urban lighting topics. Members then have access to replays on the LUCI Hub, our dedicated knowledge exchange platform.
The next LUCI Coffee Bre@k takes place on:
Thursday, 15th June 2023 at 10:00 a.m. CEST

Topic: Skyglow and light pollution in aquatic ecosystems: cause, impact and mitigation strategies
Humans traditionally live close to freshwaters and where humans are there is light. Thus, aquatic ecosystems like rivers and lakes can experience high levels of light pollution. In this talk, Andreas Jechow (IGB Berlin) will give some background information on skyglow and light pollution as well as provide an overview of its extent and some impacts focusing on freshwaters. Finally, he will also provide some information towards possible mitigation solutions.
Speaker: Andreas Jechow, Researcher at Leibniz Institute for Freshwater Ecology and Inland Fisheries
Andreas Jechow is an interdisciplinary physicist with a broad expertise in photonics, the science of light. Andreas received a PhD in laser physics from the University of Potsdam, Germany. As PostDoc he was part of the team to image the “shadow of an atom” and subsequently worked in quantum microscopy.
Since 2015, Andreas applies his knowledge on light in environmental sciences at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). His main research interest is measuring and assessing the impact of ecological light pollution, but he also co-developed environmentally friendly lighting systems. He mainly works on aquatic ecosystems from algae over zooplankton to fish, but also with bats and insects in the terrestrial realm. His hunt for dark places brought him from the winter at the polar circle to the cloudy savannah during African summer.
