The maps picture the combined effect of habitat loss and decreasing quality.
Security First features a large conversion of natural into agricultural
land. By 2032, this conversion is in full motion, especially in the Southern
Hemisphere. The Markets First scenario sees a strong decrease of the quality
of nature in most regions. In some regions agricultural land is taken
out of production and presumed to be reconverted into natural area. However,
in biodiversity terms this reconverted land is of low quality during the
first decades or longer. Policy First and Sustainability First show roughly
comparable results in the scenario period. But their trends by 2032 are
different, with Sustainability First moving towards a sharp decrease in
pressures.
Note
These maps show the change in pressure between 2002 and 2032, relative
to the 2002 situation. The development of the biodiversity situation in
absolute terms is shown in the regional bar charts. For example, the increases
in pressures in Australia and New Zealand are large in relative terms
because the pressures in 2002 are small. The reverse applies to West Asia.
