Project Title: REFRESH- Adaptive Strategies to Mitigate the Impacts of Climate Change on European Freshwater Ecosystems
Project Information
REFRESH is an EU funded project which was built on EU FP6 Project, Euro-limpacs. The main concern of the project is to generate a scientific understanding of the future status of freshwater ecosystems that is dependent on changes in land-use, pollution loading, and water demand. It has been recognized that the measures that need to be taken to restore freshwater ecosystems to good ecological health or to sustain priority species as required by EU Directives need to be designed either to adapt to future climate change or to mitigate the effects of climate. In addition, REFRESH aimed to push forward the science of integrated catchment modeling.
Duration: 02/2010- 01/2014
Funded by: European Union, funded under FP7-ENVIRONMENT, Grant agreement ID: 244121, Budget: € 9 895 943,67
Project partners: The list of all partners is available on REFRESH-partners link of the project website. METU as a project partner conducted long term mesocosm experiments under "Water management and climate change impacts in lakes and reservoirs" (WP3) task. Prof.Dr. Meryem Beklioğlu was lead the experiment carried out in METU. For detailed information about the REFRESH project, please visit the project website at http://www.refresh.ucl.ac.uk/.

Project Title: MARS- Managing Aquatic Ecosystems and Water Resources Under Multiple Stress
Project Information
MARS is a research project and supports European policies, such as the Water Framework Directive, and the Blueprint to Safeguard Europe's Water Resources. The target of the Project was water managers assessing and restoring rivers and lakes, and policymakers drafting and implementing policies related to water. The main objects of the Project were to understand the effects of multiple stressors on surface waters and groundwaters, their biota, and the services they provide to humans, to understand how ecological status and ecosystem services, to advise river basin management how to restore multiply stressed rivers and lakes, to advise the revision of the Water Framework Directive on new indicators for ecological status and ecosystem services to develop methods and software for the Programmes of Measures.
