44.0% of the 821 terrestrial ecoregions (excluding Antarctica, rock and ice) meet the target of at least 17% of their area included within protected areas, but 5.6% of ecoregions still have less than 1% protected area coverage, or no protection at all. As of 2019, over half (50.4%) of the world’s 232 nearshore marine ecoregions have at least 10% of their area protected. This is also true of marine realms (75%) and marine provinces (61.3%). Unfortunately, only 13.5% of pelagic provinces are meeting the 10% coverage target, as these areas are primarily in areas beyond national jurisdiction.
Between 2016 and 2018, 382 terrestrial ecoregions saw their coverage increase and 148 terrestrial ecoregions saw their coverage decrease. Significant positive changes have taken place in the protection of marine ecoregions over the period 2016-2018, including in the high seas. There has also been a notable decrease in the number of marine ecoregions that have less than 1% protected area coverage. Yet, in 2018 24.3% of provinces still had less than 1% of their total area protected.
Percentages of terrestrial and marine biogeographical units meeting the coverage element of Aichi Target 11 in 2016, 2018 and 2019.
The level of protection to freshwater ecosystems at the global level remains low, with various estimates having been made using different methodologies.Explore
