Landscape architecture theory
Landscape architecture and garden design are separate arts with a shared and ancient heritage. The distinction is that gardens are usually enclosed and private. Landscape architecture is concerned with public goods and public spaces. Societies require landscape architectural policies for each land use category - to conserve what has value and and to create new public goods. See the policies for: urbanisation, greenways, cycling, forestry, mineral extraction, transport, water storage, river reclamation, new towns and green towns
