In 2010, Parties to the Convention on Biological Diversity (CBD) adopted a Strategic Plan for Biodiversity 2011-2020, including its 20 Aichi Biodiversity Targets, in order to address biodiversity loss, ensure the sustainable use of natural resources, and equitable sharing of benefits. The Protected Planet Report 2018 provides an update of progress towards Aichi Biodiversity Target 11 at the global scale. Each chapter of the report examines a specific element of Target 11. The findings in the report are based on data held in the World Database on Protected Areas (WDPA) as of July 2018. For the first time, the printed Protected Planet Report is complemented by an online version, regularly updated with all the latest data, which can be explored at the following address: www.livereport.protectedplanet.net. Since the Strategic Plan was adopted, there has been significant progress towards achieving elements of Aichi Target 11, particularly in terms of land and sea coverage. However, significant efforts are needed to achieve other elements of the target.
