The 2010 biodiversity target, to “significantly reduce the rate of biodiversity loss”, agreed by parties to the Convention on Biological Diversity (CBD) in 2002, has not been met. However, only 28% of land is covered by binding local land use plans and many individual construction permits are issued on a case-by-case basis (OECD, 2011). To prevent encroachment on protected areas, including national parks, protected area administrations carry the burden of proof: they must show that development would have detrimental environmental effects.
