The difference between the two arts is that one is concerned with private space and one with public space.
Most countries now have professional associations concerned with landscape architecture.
In addition to a limited amount of garden design work, landscape architects work on roads, reservoirs, river reclamation, quarries, forests, housing development, industrial estates, urbanisation and many other types of project. The term landscape architecture was first used in a book published by Gilbert Laing Meason in 1828. It was on the Landscape Architecture of the Great Painters of Italy and provided information on a special type of architecture which could be seen in the landscape painting of the great painters of Italy. Many of Meason's examples show Italian buildings in verdant countryside. John Claudius Loudon was taken with the term Landscape Architecture, praised it in the Gardener's Magazine and cited Deepdene as an English example.
