SoilCritZone – Soil Sustainability in

Europe

WithMankasingh U., Stamati F., Banwart S., Leake J., Gaillardet J., Novak

M., van Gaans P., Rousseva S., Blum W., Aagaard P., White T. and

Brantley S.

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?

Maintaining the Soil Life

Cycle

• 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)

Drivers•Natural

•Anthropogenic

Pressures•Soil loss

•Biodiversity•Quality•Fertility•Toxicity•Pollution

State•Function

•Asset value

Impact•Economic

•Ecosystem services•On other systems

Response•Scenario evaluation by

LCA•Regulation

•Fiscal•Market forces

•Social/behavioral

DPSIR Analysis of soils

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)

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

Response models

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

European Soil Observatories

• Several sites being considered– Observatories and Satellites

• Advise from US colleagues• Unified data collection strategy• Unified data management

strategy
