• The Problem
• Human actions affect multiple ecosystem services
• No single model can capture all stressor effects

MODES

• Philosophy
• Modular different models for different suites
  of eco services
• Process-Based link effects to stressors (GCC,
  land use)
• Simple few parameters drivers
• Broad Applicability ag, forest, grassland,
  tundra
• Flexible Scales plots ? watersheds, days ?
  centuries
• Regulatory Planning Goals
• Best Management Practices balancing multiple
  eco services
• Water Quality nutrients, contaminants
• Water Quantity too little, too much
• Greenhouse gases CO2, N2O, NOx
• Habitat Wildlife effects of land use toxics
