The second Evrotas Case Study Meeting of the European research project GlobAqua “Managing the effects of multiple stressors on aquatic ecosystems under water scarcity” (2014- 2019), took place in the Museum of the Olive and Greek Olive Oil in Sparta, Greece, on the 4th June 2015. The meeting was organised by the Institute of Marine Biological Resources and Inland Waters of the Hellenic Centre for Marine Research in collaboration with “ATHENA” (Greece) and “Alterra” (Holland) Research Centres.

The project GLOBAQUA (funded by the European Commission), with the full title Managing the effects of multiple stressors on aquatic ecosystems under water scarcity aims to identify the prevalence, interaction and linkages between stressors in multiple stressor situations and to assess their effects in the chemical and ecological status of water ecosystems in order to improve water management practice and policies by taking into consideration the influence of multiple stressors.

The main added value of GLOBAQUA project is the inclusion a multidisciplinary team of leading scientists in the fields of hydrology, chemistry, biology, ecology, geomorphology, economics and sociology. In Evrotas case study, important work is conducted in the fields of hydrological, biophysical and ecological modelling, socio-economics and governance science, knowledge brokerage and policy advocacy, in order to study the interaction of multiple stressors in freshwater ecosystems within the frame of strong pressure on water resources.

The workshop was successfully facilitated by Philippe Ker Rault and Joke Luttik, both members of Alterra, part of Wagenigen University & Research Centre. The aim of that participative workshop was to discuss with the local stakeholders the services provided by the natural ecosystem and to identify their value for the society.In total 28 local representatives of various agencies and public bodies attended the workshop. The concept of Ecosystem services was extensively discussed for the Evrotas river basin. Stakeholders also commented on potential scenario developed by the IPCC (International Panel on Climate Change) and adopted for the GlobAqua project.

Several questionnaires were filled-in by the stakeholders to gather local perception of benefits but also threats on ecosystem services. Data will be used to develop an opinion poll about environmental policies that will be conducted in the Evrotas wider area in 2016. All scientific results will be presented in 2017 within the frame of the second participative stakeholders workshop. These results are an opportunity to have a new way of implementing the WFD and to open-up public discussion regarding water management policies.
