ABSTRACT

Summary

Environmental risk-based land management requires the use of spatial information analysis tools, models for assessing values, and methods for decision-making support. Specialized spatial Decision Support Systems combine Geographic Information Systems (GIS) functionality with the Multi-Criteria Decision Analysis (MCDA) methods we have used earlier in this book. This chapter presents a case study on multi-criteria risk management for contaminated land resulting from the Chernobyl accident. Specifically, stakeholders are interested in reducing the level of internal radioactive doses to local inhabitants through bans of certain food items or reduction in radioactive contamination of agricultural produce.
