ALANex brings together lighting engineers, practitioners, and experts from ecological and social sciences to reduce the negative impacts of artificial light at night while still meeting human lighting needs.

In this WSL Biodiversity Centre Postdoc project, we will investigate the relationships between woody encroachment, habitat diversity and plant species diversity. Modelled vegetation height based on historical aerial stereo images, covering 40 years of woody encroachment and forest expansion, will be combined with existing biodiversity data. This allows for a spatially explicit assessment of the relationship between woody encroachment and the dynamics of habitat and plant species diversity.

Das Projekt quantifiziert Auswirkungen von künstlichem Nachtlicht auf Bodenarthropoden (bodenbewohnende Gliederfüsser). Die Ergebnisse ermöglichen es, Herausforderungen im Zusammenhang mit der Aussenbeleuchtung und deren Einflüsse auf die Nachtbiodiversität zu entschärfen.

The spatio-temporal DGVM LPJ-GM is extended with modules for dynamics and spread of interacting species and tested in case studies with different interactors

The project investigates, to what extent residents' interactive involvement in river restoration planning enhances their understanding of biodiversity in local river areas as well as their sense of ownership, and which consequences this has on their support for local river restorations.

Urbanisation is a main driver of biodiversity and ecological change, but how the process affects biodiversity is not well understood. This project on urban ecology monitors the impact of urbanisation and establishes an Urban Living Lab (ULL) for sustainable city development.

Our project will evaluate effects of different forms of interactive involvement in river restoration projects on involved residents’ social learning and their psychological ownership and investigate whether this enhances acceptance of the river restoration projects.

Spotlight leverages options to mitigate negative impacts on the ecological environment while meeting human needs for safety and well-being. With an interdisciplinary consortium of lighting engineers, ecologists, and social scientists, we contribute to an evidence-based debate on light pollution.
