FP 7/ capacities/ research infrastructure Project idea : Development of a FRESHWATER OBSERVATORY NETWORK Summary Freshwater ecosystems provide a number of important ecosystem services including supply of drinking water, support of biotic diversity, transportation of commercial goods, and opportunity for recreation. Based on past trends it is likely that these and other services will come increasingly under stress in the future and may be magnified under the future climatic scenarios. These ecological systems are characterized by high spatial and temporal variability by non-linear dynamics and coupled with various physical/biological processes. Moreover, variability in ecological systems affects the general public and commands the attention of resource managers and policy makers. In order to understand this complexity and variability researchers must use multiple approaches, including modeling, comparative analyses, and longterm observations. The goal of a freshwater ecology observatory network is to build a scalable, persistent network of freshwater ecology observatories. Data will allow us to better understand key processes in freshwater ecosystems across different latitude , trophic … e.t.c. gradients in European countries aiming also at the implementation of the EU Water Framework Directive. Cutting-edge technologies will be used for real-time gathering of hydrological, physical, and chemical data while infrastructure for determining the ecological status should also be available. Besides serving as a resource to the greater scientific community through open access to data and opportunities for research projects that take advantage of the enhanced monitoring network, the Observatory also will provide outreach to policy makers and to the public, local communities e.t.c. in order to be realized the participatory management .
