Good land use is expressed in functional, ecologically healthy and visually attractive landscapes.  This can reduce the risks of natural disaster, protect the natural diversity of the landscape, and create visually satisfying and spiritually uplifting settings for human endeavour.

The scope of the landscape architect's work covers the whole range of human modification of the land, from the broadest outlines of regional planning through to the detailed design of home gardens and courtyards.

The landscape architect's holistic approach to the natural environment and to aesthetics complements the technical skills of other land development professionals, and produces projects which are more environmentally sensitive and have greater visual appeal.
