Two workshops brought together 20 participants to investigate why primary production remains constant despite phosphorus reduction in lakes.

The goal of this interdisciplinary project is to better understand the changes in primary production following the reduction of nutrients inputs in large lakes. To reach this goal, the Limnology Center organized two workshops in 2019:

  • On 24th and 25th January, the goals of the workshop were to identify gaps and interfaces between the different partners, as well as to sharpen the research questions. The 21 participants discussed about 6 different themes in groups and then in plenum. The participants managed to establish links, and to define a clear way forward for the future collaborations within this large project.
  • On 12th November, the 2nd workshop was dedicated to the current results of the different groups. Among the 23 participants, 12 speakers presented their preliminary results, that were followed by open discussions. These promising results gave new insights on the primary productivity of three larges lakes in Switzerland.

The project, launched in 2018, is led by a consortium from EPFL, University of Lausanne, University of Geneva, University of Applied Sciences and Arts of Southern Switzerland, Eawag and University of Constance.
