4 JRC Ispra - IES Carré & Montanarella EUROPEAN SOIL BUREAU NETWORK Soil data

5 JRC Ispra - IES Carré & Montanarella DSM basic principles European soil context How DSM can help the European policies Who are we? DSM basic principles

6 JRC Ispra - IES Carré & Montanarella To provide quantitative soil data, producible at low cost and easy-to-interpret-and-use (for other scientists and policy makers) Core - for mapping; To elaborate quantitative methods : How? - for estimating associated accuracy; Using easily accessible indirect soil information (auxiliary data) DSM basic principles

7 JRC Ispra - IES Carré & Montanarella uncertainty DSM outputs vs traditional maps Soil type map

8 JRC Ispra - IES Carré & Montanarella DSM principles Soil observations Auxiliary data Soil inference system (spatial, attribute) Soil attributes Soil classes Spatial accuracy

9 JRC Ispra - IES Carré & Montanarella 1142 samples over 3700 km 2 : contents of Cu, Pb, Ni, Zn Point observations

11 JRC Ispra - IES Carré & Montanarella Auxiliary data

15 JRC Ispra - IES Carré & Montanarella Soil attribute map

16 JRC Ispra - IES Carré & Montanarella DSM basic principles European soil context How DSM can help the European policies? Who are we? European soil context

17 JRC Ispra - IES Carré & Montanarella The European Soil Context Make a sustainable use of soil Main target Main Political frames The new Soil Thematic Strategy The Reform of the Common Agricultural Policy The UN Conventions on Climate Change, Desertification & Biodiversity To preserve soil functions against threats To solve the dilemma producing food while preserving the environment (air, water, soil) To fight against soil desertification & to preserve biodiversities To limit greenhouses gases

18 JRC Ispra - IES Carré & Montanarella The European Soil Thematic Strategy It is based on the fundamental that soil is a non renewable resource The objectives are for the EU countries to adopt specific measures for protecting soil functions against soil degradations It is been adopted by the EU Commission the 22 nd of September 06 The specific measures are addressed in a 10 years agenda It is built to fill the gaps in terms of soil protection between existing soil related politics -Basics-

19 JRC Ispra - IES Carré & Montanarella The European Soil Thematic Strategy -Functions against Threats- Biomass production Storage, filtration & transformation of nutrients, substances and water Physical and Cultural medium Source of raw material Carbon pool Geologic & archaeologic heritage Biodiversity pool Recognized functions EC (COM231/2006) Erosion Compaction Salinisation Landslide Contamination Recognized threats EC (COM231/2006) OM decline Sealing Flooding (COM179/2002) Agricultural threats

20 JRC Ispra - IES Carré & Montanarella The European Soil Thematic Strategy -Obligations for EU states- Integration into sectorial politics Precautionary measures Preventing contaminations Measures to limit and avoid soil sealing Identification of risk areas for the agricultural threats- 5 yrs Identification of contaminated sites - 25 yrs Program of Measures National Remediation Strategy PREVENTION IDENTIFICATION ACTION DSM

21 JRC Ispra - IES Carré & Montanarella DSM basic principles European soil context How DSM can help the European policies? Who are we? How DSM can help the European policies?

22 JRC Ispra - IES Carré & Montanarella Soil threats Soil observationsAuxiliary data Soil inference system (spatial, attribute) Soil attributes Soil classes Spatial accuracy Soil functions Scenario testing/ risk assessment Market / society Environment Soil processes PREVENTION MEASURES Policies requirements Delineations Preventions DSM Soil data requirements Digital Soil Assessment

23 JRC Ispra - IES Carré & Montanarella Example of applications Soil threats Soil observationsscorpan layers Soil inference system (spatial, attribute) Soil attributes Soil classes Spatial accuracy Soil functions Modelling potential erosion in Europe Use for forecasting the soil erosion dynamics

24 JRC Ispra - IES Carré & Montanarella Modelling changes in soil erosion during one decade Soil threats Soil observations scorpan layers Soil inference system (spatial, attribute) Soil attributes Soil classes Spatial accuracy Soil functions Climate (WorldClim) Biomass (NDVI from MODIS) Relief (SRTM) PESERA Model Potential erosion European Soil Database Soil crusting Time ( )

25 JRC Ispra - IES Carré & Montanarella Changes in soil erosion between 1990 and 2000 Work done by S. Selvaradjou

26 JRC Ispra - IES Carré & Montanarella Conclusions For Europe All the threats have to be delineated at the European scale and by EU countries In order to take precautionary measures against soil degradation, research should be done on - Soil functions modelling (Working Group) - Scenario modelling with necessary time series soil data acquisition For the World Big effort for delivering maps of soil properties at 90 m resolution The soil properties should be then used for modelling threats and functions Consortium of Global Digital Soil Mapping (initiative of ISRIC)

27 JRC Ispra - IES Carré & Montanarella Thank you for your interest! Unity in diversity
