Berlin Citizens Use Open Source App to Water City Trees

Thousands of residents in Berlin are using an open-source application to adopt and water local trees during repeated summer heatwaves, Good News Network reported. The application, named Gieß den Kiez, translates to water your neighborhood. It displays a map containing roughly 900,000 street trees across the city. [1]

According to Good News Network, the platform uses colored indicators to guide community efforts. Trees that require water appear as orange or red dots on the map. The application also provides specific locations for citizen-accessible streetside water taps and pumps to assist residents in retrieving water. [1]

Good News Network noted that urban trees across Europe are increasingly viewed as vital municipal infrastructure rather than decorative features. By encouraging citizens to care for local trees like pets, the initiative aims to maintain urban green spaces during periods of extreme heat. [1]
