Global biodiversity targets requires both sufficiency and efficiency

With the adoption of the 2011–2020 Strategic Plan of the Convention on Biological Diversity (CBD), 196 nations agreed to achieve ambitious biodiversity related targets. These targets encompass conservation inputs, for example increasing the amount of financial resources invested in biodiversity conservation (Target 20), conservation outputs, for example protecting areas of particular importance for biodiversity and ecosystem services (Target 11), and conservation outcomes, for example preventing the extinction of threatened species (Target 12). The evidence to date reveals limited progresses in achieving these targets, especially those related to conservation outcomes, and an alarming disparity between the rate of biodiversity decline and the rate at which conservation actions take place (Tittensor et al. 2014)
