People perceive and represent the environment that surrounds them through physical, psychological, and cultural filters, which enables them to understand the scenarios and environmental changes that occur in their environment. Many of these changes, however, can be interpreted as potentially adverse situations, that is, as risks. The analysis of risk perception can be a very useful tool in ethnobiological studies, in the search for a better understanding of environmental problems perceived and faced locally. Different methods and techniques can be used in the collection and analysis of environmental risk perception data. In this chapter, we present the interview, the stimulus with drawings, participatory risk mapping and the richness indexes and risk sharing perceived as resources that can be used to evaluate the environmental risks perceived by a particular social group.
