Jena shines in the heat check: top placement despite the area seal

Jena. A new study by German environmental aid shows how cities are prepared in climate change, especially with regard to heat development.

positive surprise for Jena

In a nationwide comparison of 190 cities for sealing area and the green volume, Jena did surprisingly well. Despite the often high temperatures and the annual heat warnings, the city shows calm, green oases and measured sealing of 37.16 percent. This could be an important incentive for other cities that fight with similar climatic challenges.

The criterion of area sealing

The examination of the DUH attaches particular importance to the area sealing, that is, how much of the city area is covered with concrete or asphalt. Area seal is problematic because it minimizes natural cooling through evaporation and shadow. Jena achieves a comparatively low seal rate with 37.16 percent. For comparison: Ludwigshafen has the highest degree of sealing with 57.75 percent

The concept of card evaluation

The cities are assessed via a map system: A red card indicates an alarming level of sealing (over 50 percent), while a yellow card means 45 to 50 percent. Jena receives a green card because the seal remains below the nationwide average.

green volume as an important criterion

Another aspect of the examination is the green volume, which describes the amount of trees and plants in the city with climate -regulating potential. Jena generates a value of 4.36, which shows that the city relies on sufficient greening to regulate the air temperature and improve the city climate.

The influence on urban quality of life

A good performance in this examination is not only a success for urban planning, but also has a positive effect on the quality of life of the citizens. With a combination of less sealed areas and a good green volume, Jena has the potential to better deal with heat and protect its citizens from the health risks of extreme temperatures.

a powerful pioneer

Thanks to such comparisons, Jena may become a model for other cities. The findings could serve to invest in urban development projects that withstand the high-temperature conditions of climate change. With a more conscious handling of surface sealing and more green space, municipalities can also ensure the quality of life of their residents in the long term.
