International policy and strategy

Convention on Biological Diversity (CBD).  This convention arose from the UN Conference on Environment and Development held in Rio in 1992. Within the framework of the convention there are 15 Guiding Principles for the prevention, introduction and mitigation of impacts of alien species that threaten ecosystems, habitats or species. The principles provide an international framework for governments and other organisations to develop effective strategies to prevent introduction, control and eradicate invasive non-native species. Article 8(h) states that each Contracting Party shall prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species. Invasive alien species are also formally addressed in the Global Strategy on Plant Conservation.

2010 Target Contracting Parties to the CBD agreed to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level. In particular, one of the seven focal areas, area (c) refers to 'addressing the major threats to biodiversity, including those arising from invasive alien species, climate change, pollution, and habitat change'
