Interception and evaporation limit the amount of summer precipitation reaching forest soils. As a result, beech and spruce trees are dominantly transpiring precipitation originating from the winter half of the year. Sufficient soil water storage is key during extended summer dry periods.

Swiss cities are more likely to accept densification when densification projects provide affordable housing and green spaces compared to densification that is implemented through reduced regulations for housing construction. By prioritizing a socio-ecological densification, extensive planning procedures and delays might be minimized. This is shown in a report from the D-BAUG Chair of Spatial Development and Urban Policy.
