For wetlands about 40 publications were found relating biodiversity intactness to catchment land use intensity. About 15 of these studies could be used for quantitative MSA calculations. A linear regression showed an average 0.8 % MSA loss per % land use in the catchment.
For riverine wetlands GLOBIO-Aquatic includes the change in hydrological regime as a pressure factor. The hydrological alteration is expressed in three disturbance levels. The data were fitted by linear mixed-effect models.
