Agricultural Land Lost to Urban Sprawl

In Canada, urban expansion almost always takes place on agricultural land and Class 1 land at that. Urban sprawl is directly related to loss of prime farmland. Population growth and urban density drive the rate or urban expansion out to the year 2100.

The total Canadian agricultural area is taken from 2006 data and the total pasture and cropland figures are from 1996. All are taken as constants with no allowance for climate change or soil degradation.
