||Aggregation is the joining of more or less equivalent elements.
Aggregation can take place across different scale-dimensions, leading to different resolutions on
these scales. The most relevant scale dimensions in environmental assessment are: temporal scale
(e.g. diurnal; seasonal; annual; century), spatial scale (e.g. local; regional; continental; global), and
systemic scales (e.g. individual plants; ecosystems; terrestrial biosphere).|
||Aggregation error arises from the scaling up or scaling down of variables to meet a required aggregation
level. In cases of non-additive variables the scaling-up or scaling-down relations
are always to a certain degree arbitrary.|
||Assessment is a process that connects knowledge and action (both directions) regarding a problem.
Assessment comprises the analysis and review of knowledge for the purpose of helping someone in
a position of responsibility to evaluate possible actions or think about a problem.
Assessment usually does not mean doing new research. Assessment means assembling, summarizing,
organizing, interpreting, and possibly reconciling pieces of existing knowledge, and communicating
them so that they are relevant and helpful to an intelligent but inexpert policy-maker or other actor
involved in the problem at hand. |
