Sustainablelandscapesparadigm Haines-Young (2000) suggested a new paradigm for landscape ecology based on the concept of natural capital: sustainable landscapes. It reflects the increased human influence on landscapes and the increasing demand to reveal the human population as part of the landscape. current landscape models are mainly science-based and these models cannot define in any complete sense an optimal or sustainable landscape. He argues that in order to deal with landscape sustainability we must recognise that in any situation there is a whole set of landscapes that are more or less sustainable, in terms of the outputs of goods and services that are important to people.
Design with Nature Isn’t the Sustainable paradigm one step back?
Canwebasethe ‚sustainablelandscapes‘ idea on thepatch-matrixconcept?
Landscape functions (individual layers) Spatialapproach: building on theobjects(here: raster cells) ‚sustainability value‘ Balance value for each cell Includingneighbouring effect
.. aggregated to spatial units (e.g. raster) ‚cost‘ calculation Infrastructure (e.g. streets, pipes, etc.) political borders topography Spatial data ..
