crescita delle aree protette tra il 1990 e il 2010 (Percentuale)
Per esempio, ci sono solo 588 siti Alliance for Zero Extinction
(Azes) che sostengono l’ultima popolazione restante di una o
più specie altamente minacciata. Il 51% di questi siti critici
sono totalmente privi di tutela, così come lo sono il 49% dei
10.993 Important Bird Areas (IBA).
Solo il 22% degli Azes e il 28% delle IBA sono completa-
mente tutelati tramite l’istituzione di aree protette.

Reduce biodiversity loss, achieving, by 2010, a significant reduction in the rate of loss

No marine area
By 2010, protected areas covered 12.7 per cent of the
world’s land area, but such protection extended to only
1.6 per cent of the total ocean area.
Since 1990, protected areas have increased in number
by 58 per cent, and in their extent by 48 per cent. But
growth has varied widely across countries and territories.
Terrestrial protection doubled between 1990 and 2010
in 59 of 228 countries with available data, and marine
protection doubled in 86 of 172 countries with available
data. In contrast, growth of less than 1 per cent, or no
growth at all, occurred in the terrestrial protected area
system of 54 countries, and in the marine protected area
system of 35 countries.
Despite their relatively small extent, marine protected
areas have expanded at a faster pace than those on
land. The extent of protection increased especially in
costal waters out to 12 nautical miles—from 3.1 per cent
in 1990 to 7.2 per cent in 2010.

Note:
Data refer to 10,993 Important Bird Areas and 588 Alliance
for Zero Extinction sites.
New research has confirmed that appropriately located
protected areas can reduce declines in status of species.
But despite an increase in these areas, half of the world’s
