Land consumption as part of human resource consumption is the conversion of land with healthy soil and intact habitats into areas for industrial agriculture, traffic (road building) and especially urban human settlements. More formally, the EEA  has identified three land consuming activities:
Since often aforementioned conversion activities are virtually irreversible, the term land loss is also used. From 1990 to 2000, 1.4 million hectares (3.5×106 acres) of open space were consumed in the U.S.. In Germany, land is being consumed at a rate of more than 70 hectares (170 acres) every day (~250 thousand hectares (620,000 acres) 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 erosion or desertification - nevertheless most of those can also eventually be tracked back to human activities. Another slightly different interpretation of the term is the forced displacement or compulsory acquisition of a native people or settlers from their original land due to land grabbing, etc.. Again, in most cases, this will be due to economic reasons like search for profitable investment and commodification of natural resources.
Even though global land loss progresses at an alarming rate, the land footprint, the area required by some Western countries can a lot larger than the land actually used or even available in the country itself.
While land prices have surged in the first few years of the 21st century, land consumption economy still lacks environmental full-cost accounting to add the long-term costs of environmental degradation.
The major effects of land conversion for economic growth are:
Nationally, 1.4 million ha of open space was lost, and the amount lost in a given city was correlated with population growthCS1 maint: multiple names: authors list (link)
About 60 per cent of the land used to meet European demand is located outside the EU. This makes Europe the continent that is most dependent on land beyond its borders to sustain its lifestyle, its agricultural industry and its hunger for energy.
The European Union uses more than its fair share of global land. In 2010, the amount of land used to satisfy our consumption, solely of agricultural goods and services, amounted to 269 million hectares – that’s 43% more agricultural land than is available within the EU itself and an area almost the size of France and Italy used outside of our borders.
