- Direct Use Value
(of Ecosystems) The economic or social value of the goods or benefits derived from the services provided by an ecosystem that are used directly by an economic agent. These include consumptive uses (e.g., harvesting goods) and non-consumptive uses (e.g., enjoyment of scenic beauty). Agents are often physically present in an ecosystem to receive direct use value.
- Drivers of Change
(Direct & Indirect) Any natural or human-induced factor that directly or indirectly causes a change in the structure or function of an ecosystem. A direct driver of change unequivocally influences ecosystem structure or processes and can therefore be identified and measured to differing degrees of accuracy. An indirect driver operates by altering the strength of impact of one or more direct drivers.
