Decision makers commonly have to deal with interest groups holding different views of the environment. For example, fishing interests may be primarily concerned with maintaining high aquatic biodiversity and view the region this way:
Hikers and birdwatchers may be most interested in preserving areas of intact forest:
Still others may be most concerned about dealing with urban sprawl and population growth:
The maps show little or no overlap between areas of greatest concern, so the groups disagree on the locations where limited resources should be focused.
It may be possible to reach a compromise using the ReVA toolkit. The decision-maker might, for example, survey the three interest groups and ask them to rate various factors:
(Check one column for each row.)
Based on these results, the decision maker can produce a map identifying areas of greatest concern to all three interest groups. Try several different combinations to see how it changes the map.
