Resumen:
This paper provides an overview of what the Millennium Assessment calls
indirect and direct drivers of change in ecosystem services. The MA
definition of 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. The categories of global driving forces
are: demographic, economic, sociopolitical, cultural and religious, science and
technology, and physical and biological. Drivers in all categories other than
physical and biological are considered indirect. Important direct drivers
include changes in climate, plant nutrient use, land conversion, and diseases
and invasive species. This paper does not discuss natural drivers such as
climate variability, extreme weather events and volcanic eruptions.
