A Land Equivalent Ratio LER greater than 1 indicates that the mixed tree-crop agroforestry system produces more total output per unit of land than would be obtained by growing the same components as separate sole crops monocultures on an equivalent total area, reflecting a productivity advantage from combining components on the same land.

Question

In agroforestry system evaluation, the Land Equivalent Ratio (LE

R is used to compare the productivity of a mixed tree-crop system against growing the same components as separate monocultures. An LER value greater than 1 for a given agroforestry system indicates that:

A The system produces more total output per unit of land compared with growing the components as separate sole crops

B The system is less productive than growing the components separately

C The system requires more land than growing the components as separate sole crops to achieve the same total output

D The system is equally productive as separate monocultures

E The system has no measurable yield advantage or disadvantage
