The source document for this Digest states: Biodiversity change is caused by a range of drivers. A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. A direct driver unequivocally influences ecosystem processes. An indirect driver operates more diffusely, by altering one or more direct drivers. Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.3, S7). No single measure or indicator represents the totality of the various drivers.
On average, for a 50% reduction in biodiversity, there will be a 10% â 20% loss of productivity. The productivity of a monocrop field is less than half that of a highly diverse field (Tilman, 2000). In part this may be due to a greater loss of nutrients from fields with low diversity than from more diversified plots.
