In environmental modeling, biologists or agricultural scientists are often able to describe a process quite well, but find it difficult to construct a mathematical model. One such a problem is the modeling of alteration in wildlife-habitat quality caused by climate change, pollution, new management methods in agriculture, etc. A further example is the calculation of agricultural yield for different management strategies under changing climate conditions. Such problems often involve uncertainties. Fuzzy-set modeling can help one to cope with this uncertainty.
Fuzzy-set theory and fuzzy-set control theory provide methods to describe:
• the input ranges for the model;
• the output ranges for the model;
• a method for defuzzification.
These methods will be further explained. To use fuzzy-set models for environmental modeling a method must be provided to enable use of these models in a spatial context. This can be done as part of a geographic information system (GIS) or with a special software toolbox like the Matlab fuzzy toolbox or the open source software SAMT.
