Information Sources

• Comprehensive summaries of information
• CABI Crop Protection Compendium

  due to
• Rapid changes in events
• Country specific information required
• Some data are incomplete or vary, e.g. trade
  pathways
• Inevitable uncertainties, e.g. climate change,
  markets, future crop production practices

Uncertainty

• In exercise book identify uncertainties
• Where information is missing may need to make
  assumptions
• With assumptions come uncertainty
• Think how risk may change with less uncertainty
