LAB for sustainable IT solutions

The Green Blue LAB is a team of solution architects, who is able to implement sustainable and green IT solutions for cities and municipalities. We use Open Source code and Open Data to build applications that help preserving the green-blue infrastructure of cities but also enable citizen participation. We are a small team having many years of experience in participation projects and IT projects. We have gained a lot of insight through our work on Gieß den Kiez (Water the neighborhood) resp. Leipzig gießt (Leipzig waters). Our team is coordinated by the non-profit foundation “Ecken wecken” and is currently still in the start-up phase.

Water City Trees with an App

Several prolonged periods of drought and the effects of climate change are now also making Several prolonged years of drought and the effects of climate change are now also making themselves visible in our cities: green spaces are more yellow than green and many a tree crown is already bare in early summer. These effects put a lot of pressure on city administrations and green space agencies since they have to raise the watering frequencies and amounts significantly to prevent trees from dying and requiring expensive replanting. However, with the help of a participatory watering app, citizen:s can be motivated to water along and help the city trees. Watering apps like Gieß den Kiez from CityLAB Berlin and Leipzig gießt from Leipzig can help cities, to engage their citizens to fill the gaps in providing the trees with enough water. The GreenBlueLab team consists of actors from both apps and has set itself the goal of using open source and open data to help the urban trees of all German cities.

Screenshot of Liepzig gießt: All city trees are visualized on an interactive map. Users can adopt trees and mark them within the app when they have watered a tree.

Example functions and Views

All trees in a city are available via a map. The color of a tree/circle shows its current water demand.

Citizens can adopt trees and enter their watering quantities. Further information about ‘their’ tree also strengthens identification.

Motivation to pour increases when pouring becomes a community event.

Various statistics make it possible to track the effect of a casting app.

At the end of 2022, Leipzig gießt was awarded the Saxon Digital Prize 2022 and took 1st place in the “Open Source” category.

An App doesn’t water a Tree on its own

Complementary to the app development, we offer the following services to communicate with and support citizens in watering trees:

  • Providing ideas and templates for for events, actions and accompanying projects, examples: Tonnen an Fallrohre (barrels on downspouts), KiTa-Kinder gießen Straßenbäume (Kindergarten children watering street trees), Schwammstadt macht Schule (sponge city makes a precedent)
  • Editorial support for blogs or social media channels. Examples: Blog, instagram, facebook
  • Design and production of logos, flyers, stickers, tree stickers, etc.
  • Organizing the distribution of supporting resources, e.g., watering bags, watering cans, etc.

With our expertise in the development of the application, the rich communication, but also in citizen participation formats on the ground, we help other cities and municipalities to implement the casting app in their own city.
