“Natural and artificial lakes are a main characteristic of the Alpine Space and belong, with their catchment areas, to the European heritage. During the last decades, authorities in charge of lakes management worked to preserve and restore this heritage and its natural resources. They now have to anticipate climate change impacts. SILMAS, by exchanging good practices and testing new methods, will supply its 15 partners with efficient tools for reaching goals of the framework directives (Water and Natura 2000) and the Alpine Convention:
- creation of a virtual laboratory, to define current ecological state of the lakes and anticipate changes due to climatic and biological dynamics,
- assessment of existing governance tools dealing with regulation of land/resources and conflicts solving, then testing decision-making instruments in different lakes sites,
- production of information and education tools for sustainable lakes management and uses, dedicated to decision makers, stakeholders and the young public.”

|Climate scenarios for study sites Lake Constance, Wörthersee, Lago di Viverone , Climate Change Impacts on Alpine Lakes (Part 1), pg. 87ff||data||EN||Scientists||Small variations in the climate conditions have remarkable effects. The results of HCILS can be used to assess a lake actual state, and they show what can be expected in the future. The water balance and residence time in alpine lakes are very sensitive to changes in air temperature and precipitation. A temperature increase of 1.4 °C until 2050 produces reductions in lake water renewal of 12 to 23 % of the annual mean (summer change is much higher with partly > 81 %. The superposition with only small decreases in precipitation (5 %) produces important reductions of lake water renewal up to more than 40 % annual mean, summer change is even higher with partly > 117 %). Land use changes (p.e. reforestation) can increase significantly these water losses (future research demand). Consequently the fill up time and mean residence time of lake water are increasing. Small lakes with small catchment areas are more sensitive to climate change. The mean residence time of lake water is not in accordance with the water renewal (or fill up) time of lakes. Its work of the limnologists to interpret the impact of these changes on the ecological and quality conditions of lakes. more about climate scenarios for study sites|

Outcomes and Impacts
Not recognised synergies
- It will be necessary to maintain databases and websites on the internet even after the project period.
- Many of the practitioner-oriented outputs seem to be useful but are not accessible anymore.
Achievements that could be further implemented
- Not only providing better access to the research results, but proactively informing potential stakeholders.
- There are no other major gaps (apart from the bad data accessibility and missing practitioner orientation).
- If supporting SSD is a major goal, then the result's usefulness should be better underlined. At the moment there is a strong focus on purely scientific outputs.
