“Scientific Basis“

risk based land management
Risk Based Land Management
  • Risk:potential or actual adverse environmental (and socio-economic) effects
    • Human health
    • Ecological health
      • As related to human landuse (agriculture,gardens, parks)
      • Nature, wildlife
      • Hydrological cycle (spreading to groundwater and surface waters)
      • Buildings
  • Land
    • spatial soil management unit
  • Management
    • Manager: industrial owner, municipality, province
    • Decisions: clean up, landuse restrictions, monitoring, spatial planning, aftercare, and other issues
key issues in decision making
Key issues in decision making
  • The time frame
    • Assessment of risks and priorities
    • Longer term effects of particular choices
  • The choice of solution
    • Assessment of overall benefits, costs and environmental side effects
    • Value and circumstances of the land
    • Community views and other issues
  • Objectives
    • Fitness for use
    • Protection of the environment
    • Long-term care
the nunspeet workshop
The “Nunspeet” workshop
  • Initiated by CLARINET
  • Comparison of approaches
    • USA: wildlife oriented
    • EU: soil resource oriented
    • Assessment of chemicals vs. assessment of soil
  • Common ground
    • A tiered approach
    • Toolboxes
  • Informal ecorisk network
    • Focal points CONSOIL and SETAC meetings
  • LIBERATION and NOMIRACLE projects
concluding remark be careful with eu harmonization
Concluding remark:“Be careful with EU harmonization”
  • Contaminated land management differs from environmental “anti pollution” policies
    • Legacies from the past
    • Finite clean up programs versus permanent care in other environmental policies
  • Various stages of completion in EU-MS
    • Decision making criteria may vary accordingly
  • A complete inventory is not feasible in a reasonable number of years, action cannot wait for inventory based priority setting
    • Spatial planning becomes the driving force in most clean ups
