Resource evaluation: land

The resource of land – especially semi-natural land of sufficient size – is a scarce commodity, especially in densely populated countries and regions. However, a large number of plants and animals are dependent on the presence and availability of this semi-natural land.The specific protection goal of the land use indicator is based on its semi-natural characteristics.
Three significant factors can be derived here to determine the semi-natural state and the biodiversity of the land.
Land size [m²], useful life [a] and land quality [semi-natural state]. As the land quality indicator has not yet been finalised, the land utilisation is shown only as a life cycle inventory parameter – “land x time”.

The hemeroby levels taken from landscape ecology (naturalness class) could be utilised in future to illustrate the semi-natural state of the land. It is classified into seven naturalness classes from I “natural” (i.e. no human influence, e.g. virgin forest) to VII “not natural” (i.e. long-term built-up, sealed or devastated areas).
