Land is a primary input for all agricultural production. 33% of the world’s land is used for agriculture, and 1/3 of that is used for crop production. Efficient land use is a top priority and concern for agricultural producers, and because the world’s population is increasing and there are competing demands for land use (urban areas, forestry, natural areas, etc), efficient land use to produce crops is an important measure of sustainability.

The land-use efficiency indicator is the simplest of the four Canadian Field Print Calculator indicators. It estimates the amount of land required to produce a unit of crop. Instead of measuring tonnes produced per hectare, land use efficiency measures the number of hectares required to produce a tonne of crop.

Provincial Averages

In the 2013 crop year on Field 1 your yield was 56 bu/ac (3.14 tonne/ha), so you used 0.319 hectares to produce each tonne of canola. The 2013 provincial average for Alberta was 0.4 ha/tonne, based on an average yield of 2.50 tonne/ha (higher than the three-year average of 2.20 tonne/ha). The chart above shows the Land Use Efficiency of your 2013 crop on Field 1 in relation to the long-term provincial trend for canola in Alberta. A low LUE indicates relatively more sustainable production.
