Since often aforementioned conversion activities are virtually
irreversible, the term land loss is also used. From 1990 to 2000,
of open space were consumed in the U.S.
In Germany, land is being consumed at a rate of more than every day (~ per 10 years).
In European Union, land take is estimated approximately about to 1.2 million hectares in 21 EU countries over the period 1990–2006.
Land loss can also happen due to natural factors, like
