4.  Modeling the Life Cycle of Soils

• a)  Can we ground truth the new models?
• b)  Can we delineate risk areas?
• c)  Can we define appropriate management measures
  to alleviate the threats (restoration measures)
  and achieve soil sustainability?

3
Available Models

• General Solute Circulation Models - processes
• Economic valuation (of soil function) models
• Meta-models for geomorphology
• Meta-models for decision/policy (lumped
  parameters, spatial aggregation)
• Detailed process models from molecular to
  catchment scale (discipline specific, analysis
  tools)

DPSIR Analysis of soils

• Drivers
• Natural
• Anthropogenic

• Pressures
• Soil loss
• Biodiversity
• Quality
• Fertility
• Toxicity
• Pollution

• Response
• Scenario evaluation by LCA
• Regulation
• Fiscal
• Market forces
• Social/behavioral

• State
• Function
• Asset value

• Impact
• Economic
• Ecosystem services
• On other systems

5
Driver Pressure models

• CLORPT (Climate, organisms, relief, parent
  material and time)
• Soil development (Baseline)
• Landscape development
• Soil Evolution Evaluate Deviation
• From base line due to anthropogenic influences
  (present state)

6
State Impact models (need to be developed)

• Soil profile Catchment Continental Scale
• Soil profile impacts Eco-services
• Catchment impacts Other systems (anthropogenic,
  Hydro)
• Continental impacts Economic
• Other scientific gaps Parameters needed to
  assess soil critical zone system?
• Observatory design

7
Response models

• LCA (Life Cycle Analysis Models) Assessment
  Management
• Socio - economic valuation methods
• Social costs/benefits
• Health costs/benefits
• Commercial Impacts
• Energy needs

8
European Soil Observatories

• Several sites being considered
• Observatories and Satellites
• Advise from US colleagues
• Unified data collection strategy
• Unified data management strategy
