“…WCED, 1987), and are used as indicators of progress in the protection of biological diversity by a number of international agreements, including the Convention on Biological Diversity (CBD) Analyses of progress towards Target 1.1 have to date tended to measure protected area coverage (Chape et al, 2005, Coad et al, 2008, Spalding et al, 2008, Coad et al, 2009a, Coad et al, 2009b, Jenkins and Joppa, 2009 and ecological representativeness (Rodrigues et al, 2004, Spalding et al, 2007, Schmitt et al, 2009, Herbert et al, 2010 facilitated by the availability of open-access global datasets on protected area locations (e.g. The World Database on Protected Areas -WDPA) and global frameworks of ecological regions and key areas for biodiversity (Olson et al, 2001, Eken et al, 2004. In terms of global protected area coverage, Parties have made significant progress towards achieving Target 1.1 for terrestrial biodiversity: over 50 per cent of terrestrial ecoregions have 10 per cent or more of their area within protected areas, although marine ecosystems are still severely under-represented (Spalding et al, 2008, Coad et al, 2009b.…”
