3.9 Protected areas (original) (raw)
This scenario defines the targeted protected share of natural land in each ecoregion by 2050. Depending on the historical distribution, this results in specifically defined amounts of protected forest and other natural land, which cannot be changed to another land type in the calculation process.
By default, two scenarios are defined: No change and PA expansion. No change keeps the protected area share constant at 2010 levels, based on the WDPA database. By default, PA expansion targets a protected share of at least 17% for each ecoregion by 2050. Ecoregions with a higher protected share in 2010 as well as ecoregions with a protected share below 5% are kept constant at 2010 levels. Using the resulting 2050 protected areas targets, targets for each time step are calculated depending on the selected implementation rate (cf. Implementation Rate).
