Soil use is becoming increasingly intensive. From use for agriculture and housing construction to recreation and infrastructure. At the same time, we also depend on the soil-watersystem for a healthy living environment, restore biodiversity, countering climate change, energy transition, absorption of rainwater and keeping groundwater clean.
