Halo Habib, my key points on these concepts:

Land evaluation: land assessment and may be physical and/or human depending on selected criteria.

Land Allocation: The selection and apportioning of land (parcels) for specific use or to be conserved or preserved.

Land use: the actual use to which land is put.

Land cover: the materials that overlay any given piece of land, may be grasses, impervious materials, or soil fractions.
