Bois de Jussy is managed to maximise the biodiversity, and to welcome the public for walks, jogging and biking to relax, cool off, reconnect with nature by observing ponds.
Freshwater ecosystems in the Swiss plateau are threatened by multiple stressors that deteriorate water quality and hydromorphology. This is the result of channelization, dams, wastewater, and agriculture, among other causes. To restore these ecosystems and stop the biodiversity decline, multiple management measures will be implemented over the next decades. We propose methods for prioritising the location and timing of restoration measures to maximise their effectiveness, considering many sectors and multiple societal objectives.
15 large ponds (5000m2 to 30’000m2) as well as many medium and small sized ponds have been created between 1970 and 2018. Some ponds have been dug to rehabilitate and recreate natural habitats in brownfields and others to create recreational activities such as swimming and fishing. They depict the multiple roles a pondscape can play.
The objective of the spatial delimitation of these pond uses is to promote simultaneously the protection of pond biodiversity and the delivering of numerous NCPs.
By 2100, under a high greenhouse emissions scenario, the temperature is projected to increase by about 4.5 ºC in comparison to the 1990s. This means that every second summer will be as hot or even hotter than the temperatures reached during the 2003 heat wave which caused severe loss of life across Europe. Extreme precipitation events are likely to increase in frequency and severity. Green roofs were found to offer opportunities to combine energy saving, climate change mitigation and adaptation, and biodiversity objectives. In densely built-up areas where providing extensive parks and...
