Citizens can take on a symbolic sponsorship for trees and actively participate in the watering of urban trees using mobile apps. An app tells them how to water the tree. Linked with other sensors, such as weather and soil sensors, more precise analyses of the soil's absorption capacity can be taken into account. With the help of sensor data, the idea of "tree sponsorship" can thus be further developed. This will optimize irrigation in a decentralized, resource-saving manner. Open-source approaches already exist for this solution, which can be implemented very cost-effectively for cities.
In order to create globally sustainable structures, the member states of the United Nations have set themselves 17 goals by 2030, which are set out in the 2030 Agenda for Sustainable Development.
