Causes - Global Changes Global Climate Change Land Use Change
Consequences - Environmental Invasive species are among the top drivers of environmental change globally (Sala et al. 2000). At risk: BiodiversityBiodiversity Ecosystem ServicesEcosystem Services Sustainable Development (SIDS)Sustainable Development (SIDS)
Consequences - Economic Losses to agriculture globally: $55-248 billion/year. Costs to U.S. estimated to be at least $100 billion/year (Pimentel et al. 2000). Introduced from Latin America as a high protein food source, the golden apple snail caused losses to Philippine rice crops during the 1980s of @ $1 billion (Naylor 1996).
Consequences - Human Health Disease epidemics Increased pesticide use Food and water shortages
Consequences - Political Barriers to international trade and economic growth Freight Solutions Intl. Invasive alien species could prevent governments and industries from: Selling some types of food products Selling some types of food products Selling living commodities Selling living commodities Using certain kinds of containers Using certain kinds of containers
Consequences - Political Biosecurity Deliberate attacks using biological agents Humans Humans Wildlife Wildlife Domestic animals and agriculture Domestic animals and agriculture
International Instruments Legally Binding For example: Convention on Biological Diversity (CBD; 1992) Article 8 (h): Prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats, or species. Guiding PrinciplesGuiding Principles Work PlanWork Plan There are more than 40 intl agreements, as well as numerous soft law tools that address invasive species.
