As climate change escalates, the Berlin-Brandenburg region faces new challenges. Climate change-induced extreme events are expected to cause new conflicts to emerge and aggravate existing ones. To guide future research, we co-develop a list of key questions on climate and water challenges in the region. Our findings highlight the need for new research approaches. We expect this list to provide a roadmap for actionable knowledge production to address climate and water challenges in the region.

Understanding water balance in lakes is complex. We studied Lake Groβ Glienicke in Germany, using an innovative method that combines isotope measurements and a hydrological model to improve estimates of water inflow and evaporation. Our findings show a high correlation between the two approaches, leading to better predictions of lake water dynamics. This research offers a reliable way of evaluating the model outputs.

Short summary
This paper applies a coupled 3D surface–subsurface model to a degraded fen peatland using long-term field data on evapotranspiration, groundwater, vegetation, and ditch water levels. By explicitly representing layered peat degradation and vegetation-controlled evapotranspiration, it enables consistent quantification of all water-balance components. The results provide process-based insights relevant for peatland rewetting under climate variability.
