For the purpose of this assessment, drivers are defined as the factors that, directly or indirectly influence the sustainability of use of wild species, by changing the abundance or distribution of species in use, altering demand on and consumption of wild species, products derived from wild species and/or changing the (nature, scale, and/or intensity of) interactions with wild species in use (practices). It is recognized that the same factor may influence different components of the system (wild species, practices, Nature’s contributions to people); and the interactions among these factors vary across time and space, which can have negative or positive effects on sustainability.
