Dresden presents concept for climate adaptation

The city of Dresden wants to be better prepared for extreme weather. To this end, the municipality has presented a new "climate adaptation concept". It describes how to prepare for changing climatic conditions such as drought, heavy rainfall and heatwaves. "It was particularly important to us to focus on the health of all people in our city and to minimize the risks of damage to infrastructure and buildings," explained Eva Jähnigen (Greens), the mayor responsible for the environment.

Removing damage costs more than preventative measures

According to Jähnigen, the aim is to reduce climate-related risks for the local economy, infrastructure and buildings in the city. As a rule, repairing damage always costs more than prevention. The focus is on urban development measures. For example, green spaces are to be provided as cool recreational areas and corridors with better ventilation are to be created.

Dresden does not want to let water seep away as a sponge city

Dresden also wants to become a "sponge city". Roughly speaking, this means better handling of rainwater in order to reduce flooding during heavy rainfall, replenish groundwater, supply the city greenery and thus contribute to cooling. Rainwater should not simply disappear down the drain, but should be collected and stored in green spaces, on green roofs and on the ground wherever possible.

Climate in Dresden has already changed significantly

"The urban climate in Dresden has already changed significantly and the climate change trend clearly shows that it will continue to change significantly. The city's measurement data impressively reflects the global climate changes," it said. The effects can be seen in the form of rising temperatures, heat or extreme dry periods, such as in the period from the end of 2017 to 2023, as well as changing patterns in annual precipitation.

The data analysis shows which districts are more affected by heat or flooding. For example, Striesen, Leuben, Gruna, Johannstadt and Äußere Neustadt have the highest risk potential in terms of heat stress. In the case of flooding due to heavy rainfall, 13 districts are at the highest risk and 22 districts are at increased risk. For flooding, the figures are six and 20 districts respectively.
