[...] > 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. [...] I = (V – VL) / (VH – VL) where I is the value of the indicator, V is the value of the variable, VH is the high condition score and VL is the low condition score. [...] 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.
