Invasive Species In Asia: A Management Challenge to Sustainable Crop Production Wai-Hong LOKE, CABI SEA Invasive Species Presentation • • • • • • Introduction to invasive species (IS) and context Invasive species - a management challenge Effects and consequences Addressing the problem About CABI and IAS Summary 1. Introduction to Invasive Species Invasive species are plants, animals or micro-organisms that are not native to a specific ecosystem and whose introduction threatens biodiversity, food security, health or economic development. 55 Global / Regional Context • • • • • • • • • • Occur in all major taxonomic groups of biological organisms One of greatest threats to ecological and economic well-being of planet Direct and indirect effects are serious and often irreversible Serious problems in many economic and health sectors Trade-related IS problem to market access vis-à-vis WTO IS cost > $1 trillion per annum (nearly 5% global GDP) Increasing – travel, trade, transport, tourism Exacerbation by climate change Lack of biosecurity planning against IS Global in scope and requires international cooperation to supplement actions at national and local levels International Regulatory Framework No more trade restriction than necessary Plant Protection IPPC LMOs identified as pests CP WTO-SPS Trade Protecting wild flora CBD Trade while protecting biodiversity LMOs Protecting biological diversity Some of the Asia’s Worst IS 1. Banana bunchy top virus 2. Papaya ring-spot virus 3. Water hyacinth (Eichhornia crassipes) 4. Giant mimosa (Mimosa pigra) 5. Golden apple snail (Pomacea canaliculata) 6. Sweet potato whitefly (Bemisia tabaci / argentifolii) 7. Fruit Flies (Bactrocera spp.) 8. Rice planthoppers (Nilaparvata, Nephotettix) Serious management challenges 2. IS – A Management Challenge General Traits/Characteristics of a Successful IAS • • • • • Large reproductive output Rapid growth rate Efficient dispersal capabilities No / lack of natural enemies Broad environmental tolerance An Important Management Consideration “Pathways” the means by which an invasive species is moved “The 4 T’s” • • • • Trade (expanded) Travel (faster) Transport (further) Tourism (increased) TRADE Packing materials Planting materials Cut-flowers TRAVEL TRANSPORTATION rising temperature, air humidity, CO2, N2O, CH4., rainfall, fire risks Pest complex Crop Weed community changes in soil water / nutrient dynamics Effect of higher temperatures on crop yields 20 -10 -20 -30 -40 -50 Rice Maize Wheat Rice Maize Wheat -60 Temperate 0 } } Tropics % Yield change 10 5 4 3 2 1 o mean local temperature change ( C) adapted by Norgrove from IPCC (2007), summarising 69 studies < 3 oC increase > 3 oC increase Any increase higher yields in temperate zones lower yields in temperate zones lower yields in tropics Predicted crop yield declines in the Tropics Furthermore, ● Climate change will alter pest / crop / soil dynamics ● Ranges of some pests may expand to higher altitudes & latitudes ● More extreme climatic disturbances will create opportunities for pest colonisation and establishment 3. Effects of IS • Competition with native taxa of flora and fauna • Hybridization with genetically close species • Changes in physical & chemical characteristics of soil • Modification of natural and semi-natural habitats • Disruption of ecosystem services • Propagation of pests and diseases Consequences: Environmental Waterhyacinth Introduced from Latin America as ornamental plant, has eliminated more than 10 native aquatic plant species and more than 15 native freshwater fishes in Lake Rawapening, Indonesia (Soerjani, 1982, 1996) Consequences – Environmental One of top drivers of environmental change Great threat to species composition of ecosystems Second to habitat loss in biodiversity disruption Cascading effect on biological systems / food chains Deplete natural resources, e.g. water Disrupt ecosystem services One of most serious environmental challenges Consequences: Economic Golden Apple Snail Introduced from Latin America as a high protein food source, the golden apple snail caused losses to Philippine rice crops during the 1980’s of $1 billion (Naylor 1996) Consequences – Economic Significant damage / losses in key economic sectors, e.g. agriculture, forestry Impact on food security Barriers to sustainable development Impediments to trade Significant costs in control operations / inputs Issues of compensation in quarantine situations 4. Addressing the Problem Goals: • Prevention • Early Detection • Eradication • Control • Restoration Addressing the Problem Processes: Risk Assessment and Management Research Monitoring Publicity and Education Policy and Regulation Information Management Measure Accomplishments Multi-agency / stakeholder cooperation, collaboration and capacity building are essential Addressing the Problem Scientific Challenges: • Complexity • Uncertainty • Mobility (both invaders and pathways) • Time lags Addressing the Problem Political Challenges: • • • • • • Lack of awareness Mustering resources Lack of coordination Speed of operations Conflicting policies, policy gaps High costs / financial issues Addressing the Problem Ethical Challenges: • • • • Animal rights Risks of pesticides Risks of biological control GMOs Ten Strategic Responses to Manage IS Element 1 Element 2 Element 3 Element 4 Element 5 Element 6 Element 7 Element 8 Element 9 Element 10 Build management capacity Build research capacity Promote sharing of information Develop economic policies and tools Strengthen national, regional and international legal and institutional frameworks Institute system of environmental risk analysis Build public awareness and engagement Prepare national strategies and plans Build IAS issues into global change initiatives Promote regional/international cooperation to deal with the problems of invasive alien species 5.
