Environmental riskbased land management requires implementation of tools for spatial information analysis, problemoriented models for assessment of risk values, and computer systems for decision making support. A new Decision Support System (DSS) DECERNS (Decision Evaluation in Complex Risk Network Systems) has been developed to address this class of problems. DECERNS is a webbased Spatial DSS (WebSDSS) for multicriteria analysis of a wide range of spatiallydistributed alternatives within the problems on risk management and landuse planning. This paper provides a brief overview of methods and tools used in DECERNS; application of DECERNS for a case study on multicriteria risk management for contaminated land resulting from Chernobyl is presented.
