Figure 1.
In green wetland areas (including lakes and areas with partial wetland cover) from the Global Lakes and Wetland Database (from Lehner and Döll, [27]).
Figure 2.
Proximate and underlying drivers of wetland conversion.
Figure 3.
Number of times proximate causes of wetland conversion are documented in the 105 analyzed case-studies.
Figure 4.
Most frequent occurring combinations of proximate causes and underlying forces of wetland conversion.
Agricultural development includes pasture expansion. For each proximate cause at least the two most important underlying forces are indicated, and for each underlying force at least two associated proximate causes indicated.
Figure 5.
Number of times underlying forces of wetland conversion are documented in the 105 analyzed case-studies.
Figure 6.
Probability of conversion of wetland areas and converted and non-converted wetland sites (data set 4).
Grey areas are non-wetland areas. Wetland areas are defined based on the Global Lakes and Wetland Database [27].
