Ecosystem Condition accounts Ecosystem condition • Ecosystem condition: quality of an ecosystem measured in terms of its abiotic and biotic characteristics. [...] • Key role is integrating data • Ecosystem condition is often defined by measuring the similarity (or the distance) of a current ecosystem to a reference state, such as minimally impacted by people or a historical state Condition accounts • SEEA EA: a three-stage approach to account for ecosystem condition. [...] > Outputs at each stage are relevant for policy and decision making > The primary spatial units are ecosystem assets and these are expected to be delineated such that they are reasonably homogeneous in terms of their main characteristics • Ecosystem condition indicators are rescaled versions of ecosystem condition variables • The simplest conversion uses two reference levels to reflect a high or l. [...] Variable account Reference levels • A reference level is the value of a variable at the reference condition, against which it is meaningful to compare past, present or future measured values of the variable • A reference condition is the condition against which past, present and future ecosystem condition is compared to in order to measure relative change over time. [...] CONDITIONS ACCOUNTS:The SEEA-EA condition is a metric that captures, through a set of key indicators, the state and functioning of the ecosystem in relation to both its ecological condition and its capacity to provide ecosystem services.
