|Description=For the “Rethinking global biodiversity strategies” scenario study on future biodiversity developments, a set of policy options was designed and implemented (see [[ten Brink et al., 2010]]).
In the absence of additional  forest policies, the area of productive plantations is assumed to increase only slightly in the baseline between 2000 and 2050 (from 1.1 to 1.2 million km2). As a result, the total forest area in use for wood production increases from 9.5 to 14.5 million km2 (see  left panel figure ). In 2050, just over a third of the global forest area will be in use for production. As a consequence of the increasing area for forestry, the area of primary and restored (=unused) forest decreases with more than 6 million km2, starting from almost 30 million km2 in 2000.

|Example=Two different ambitions for introducing improved forest management were implemented, analysed, and compared to the baseline (see figures 1 and 2 below):
# a moderate ambition option (“FM-Low”) with partial substitution of conventional selective logging in tropical forests by RIL practices, and plantation establishment targeted at 25% of global wood demand;
# a high ambition option (“FM-High”) with full substitution of conventional selective logging by [[hasAcronym::RIL]] practices and plantation establishment targeted at 40% of global wood demand. This still represents a plausible development for future plantation growth (Brown, 2000). Application of RIL measures is implemented immediately in 2010, while plantation establishment continues up to 2050.
The ambitious implementation of improved forest management (SFM-H) results in considerable less land-use for forestry by 2050. The globally required forest area increases by only 0.5 million km2 between 2000 and 2050, and now a total of about 10 million km2 will be in use (two thirds compared to the baseline). With such a reduced forest use, and the assumed positive effects from applying RIL, the biodiversity loss through forestry is lower. For the less ambitious option, the gains are of course smaller, with an expansion of the forestry area of well over 3 million km2, and less avoided biodiversity loss. See figure 1,  Prevented loss is measured in [[hasAcronym::MSA]], see Biodiversity component.
