The NamTip members from the University of Potsdam were actively involved in the Tropentag 2025 conference, held in Bonn from 9-12 September 2025. The event began with a pre-conference workshop co-organized by Dr. Thomas Bringhenti and PhD student Lisa-Maricia Schwarz . The workshop, open to all participants and interested attendees, was titled "Tipping Points in Social-Ecological Systems: Challenges and Insights Across Diverse Contexts of Land Management" (Fig. 1). The session brought together researchers from multiple disciplines to explore tipping points in social-ecological systems across a range of landscapes, including rangelands, forests, and agricultural systems. Expert presentations by NamTip scientists and invited guests fostered cross-project dialogue within the GlobalTip research network. The workshop concluded with a lively discussion on the drivers, early-warning signals, and impacts of tipping points. Participants reflected on the shared insights, highlighting both conceptual and methodological challenges, such as data limitations, uncertainty, and the integration of social and ecological perspectives.
But the involvement of NamTip members in Tropentag 2025 extended well beyond the pre-conference workshop. Throughout the main conference sessions, University of Potsdam scientists presented their latest research findings and chaired discussions across multiple thematic areas.
Dr. Thomas Bringhenti chaired a session on "Rangelands and Forage", where Lisa-Maricia Schwarz presented results on how drought and intensive grazing influence rangeland productivity, and how land-use history affects the ecosystem’s response to these pressures (Fig. 2). In addition, Lisa-Maricia Schwarz chaired an online poster session on "Biodiversity". Finally, Dr. Thomas Bringhenti presented a poster on his PhD research examining the water use of macadamia trees in South Africa, which was awarded as one of the best five posters of the entire conference (Fig. 3).
