The human civilisation is becoming ever more urban. With the growing densification in our cities, open, green spaces are put under pressure. As a person living and commuting between the Austrian and Slovak capital, I see the increasing number of built, non-permeable surfaces (such as asphalt and concrete) increase. Occasional and sudden events such as overflowing streets of Vienna after a heavy rain or snow melting down, an overheated square in central Bratislava during the summer period are a result of continuous, reckless paving of our cities. This is not climate change. This is visionless urban planning.
