Pilotprojekt zur Beobachtung der Erosion bei Kulturen, um vorbeugende Maßnahmen zu ergreifen
Soil erosion decreases the yield capacity of soils by the loss of soil on the surface. Außerdem kann sie Bodenwasser mit Sedimenten, Nährstoffen oder Schadstoffen kontaminieren. However, erosion problems are generally not considered as priorities and measures taken to fight against them are often insufficient. In addition, it is difficult for the cantonal services to observe in the field all situations that actually induce erosion and to be able to propose appropriate measures. New technologies, such as the use of aerial images taken by drones or low cost Unmanned Aerial Vehicule (UAV) coupled with radar precipitation data, offer new possibilities for documenting these situations and proposing preventive measures.
The Swiss Federal Office for Environment wants to exploit these new technologies in order to see whether it is possible to highlight erosion traces after an important rain event with the help of aerial images taken by an UAV. Dieses Projekt ist Teil der Fortsetzung des Projekts Agrovision, das die Entwicklung von Bildbeschaffungsmethoden ermöglichte. The objectives of this research project are:
- To document erosion events by field measurements and aerial images
- To document cultural practices leading to erosion events
- To compare field measurements and image analysis
- To analyze aerial images to calculate the volume of erosion channels
- To develop a prevention and non-control tool
