The sponge city concept
We work with sponge city concepts to improve rainwater management in cities and agriculture. The idea behind the concept of the sponge city is to absorb water like a sponge, store it and release it back into the environment when needed. A nature-based concept for a sustainable, livable and innovative future.
The central and current problems
The central problems of cities include the high degree of land sealing, outdated rainwater management and the increasing, noticeable consequences of climate change, such as rising temperatures and water shortages on the one hand, and floods on the other.
The climate is changing significantly, which is particularly noticeable in cities and agriculture. Higher temperatures, a redistribution of summer and winter precipitation, and an intensification and increase of extreme events.
Currently, the precipitation is not used, but only discharged via the canal. Due to a lack of infiltration, the groundwater supply decreases and the risk of flooding increases. A lack of precipitation storage for the irrigation of green spaces is compensated for by the use of important drinking water.
Yields in agriculture
Climate change, extreme events and a decline in soil quality are leading to declining yields. At the same time, farmers are being restricted by ever stricter requirements, so that there are hardly any opportunities to secure yields.
