Figure 5. Methodological approach of the
energy-information-structure model (see Annex B ): a)Graph model of the interlinked energy carriers flowing in an
agroecosystem. b) From the graph model, we can calculate the
energy investment (E ), the energy information (I ), and the
energy ‘imprint’ in the landscape structure (L ). c) The
resulting mathematical model allows to calculate a three-dimensional
relationship among E , I and L (as an example five
land-cover typologies are represented), conforming a particular
human-transformed landscape.
