In a commons dilemma a collective opportunity,
or resource, exists from which all individuals may consume. This stylized
concept guides a lot of research in environmental science, social
psychology, economics and institutional science, for theoretical,
experimental and field research. Because of the large amount of
empirical information and the relevance for environmental management we
used this concept as a leading guide for a number of applications of the
consumat approach. We study how individual characteristics and behavioural
rules affect the long term dynamics of a common (renewable) resource. Our
studies show how uncertainty can stimulate imitation which promotes
over-harvesting. Increase of uncertainty leads to increase of
over-harvesting.
